Vehicles include sensor pods connected to the vehicle. The sensor pods gather data and information, communicate with the vehicle, and may assist in navigating the vehicle. The sensor pods are connected to the vehicle by connecting assemblies. There remains a need for improved assemblies, systems, and methods for connecting sensor pods to vehicles. As described and shown herein, these may include, for example, a connecting assembly that reduces damage and debris in the event of a collision, a quick swap sensor pod, and/or a universal bracket or attachment.
In one aspect of the present disclosure, a sensor pod may flex back after an impact to reduce damage and debris after a collision. The connecting assembly may allow rotation on impact but is securely held with shear bolts to prevent vibration. In another aspect of the present disclosure, the quick swap sensor pod may be changed quickly, for example, in a few minutes. The connecting assembly allows for quick removal and/or install. Bolts are not required to initially mount the sensor pod to the vehicle.

In another aspect of the present disclosure, a sensor pod may be swapped by one individual without the need of additional support structures to manage the weight and positioning of the sensor pod.
In one aspect, the connecting assembly may include features to provide for alignment and position control of the sensor pod. For example, in a connecting assembly having a bracket and sensor pod arm, as discussed in more detail below, the sensor pod arm and bracket can be configured to provide for alignment and position control of the sensor pod when assembling the bracket and sensor pod arm. These features can reliably position the bracket and sensor pod arm such that they are in contact and/or in touching contact with each other, as described in more detail below. Various bracket and sensor pod arm contact configurations are contemplated, including one or more features to facilitate the alignment and/or contact. For example, in some examples, side surfaces of the bracket and sensor pod arms are in alignment with each other and may be in contact with each other. In some examples, raised portions of the bracket and the sensor pod arm are in alignment with each other and may be in contact with each other. Configurations that are compatible with manufacturing may be beneficial. The feature(s) and configurations can be configured, designed and/or manufactured to provide for reliable alignment and, in some examples, contact between the bracket and the sensor pod arm. The feature(s) can control a position of the sensor pod arm relative to the bracket and help align the connection between the sensor pod arm and the bracket. Details of the alignment, control, and in some examples, contact, are described in more detail to follow.

As mentioned, the sensor pod 12 may take many forms and may include a lidar 16, such as described, for example, in International Patent Application No. WO 2020/180707. The sensor pod 12 is illustrated blank for purposes of description, however, as mentioned, the sensor pod 12 may include mirrors, sensor, and the like. See, for example,

The sensor pod arm body 202 may include a sensor pod arm flange 234 extending laterally past the side surface 212 and having a side 209 (
Referring to
The first connection 102, the second connection 104, and the third connection 106 provide an anti-vibration system for the sensor pod 12. That is, the first connection 102, the second connection 104, and the third connection 106 connect the sensor pod 12 to the vehicle 10 in a manner that prevents or limits relative movement between the sensor pod 12 and the vehicle 10. As used herein, the terms “fix”, “fixate”, “fixed”, “rigid”, “rigidly” or the like refer to such a connection where relative movement is prevented or limited between two parts.
Accordingly, the first connection 102 fixates the sensor pod 12 about the first axis A1 to provide a first fixation point. The first fixation point limits movement between the sensor pod arm 200 and the bracket 300 in both a vertical direction V (due to the securing of the fastener 230 to the bracket pin 318) and in a lateral direction L (due to the interaction between the bracket pin 318 and the opening 226). The second connection 104 fixates the sensor pod 12 about the second axis A2 to provide a second fixation point and the third connection 106 fixates the sensor pod 12 about the third axis A3 to provide a third fixation point. Each of the second connection 104 and the third connection 106 limit movement between the sensor pod arm 200 and the bracket 300 in the rotational direction R about the first axis A1. Thus, the first fixation point, the second fixation, and the third fixation point create a rigid connection between the sensor pod arm 200 and the bracket 300 to prevent or limit relative movement in all directions between the sensor pod arm 200 and the bracket 300. Although three fixation points are illustrated and described, only two fixation points are required: the first fixation point and a second fixation point spaced apart from the first axis A1 (e.g., the second connection 104 or the third connection 106). Thus, the second fixation point may occur at either of the fasteners 238 extending through the opening 236 and the opening 330 or may occur at other locations spaced apart from the first axis A1 such that the second fixation point creates a moment through the fastening force between the arm 200 and the bracket 300 that counteracts any rotation of the sensor pod 12 about the first Axis A1. The placement of the second fixation point may preferably be perpendicular to the Axis A1 so that the predetermined loads for shear (as described below) may be along the axis of the second fixation point. The second fixation point may also be along an axis that has a perpendicular component to the first Axis A1. Thus, the second connection 104 or the third connection 106 may be optional and may be omitted. In some examples, a single fastener 238, a single opening 236, and a single opening 330 may be provided. In some examples, more than two fasteners 238, more than two openings 236, and more than two openings 330 may be provided such that more than two fixation points are provided about the rotational direction R.
The first fixation point, the second fixation point, and the third fixation point, refer to locations of fixation, but do not limit fixation to a single, finite point. As described previously, these fixation points are with respect to axes. The aforementioned fixation points prevent, limit, and/or reduce vibration of the sensor pod 12 since the sensor pod 12 is now rigidly connected to the vehicle 10 (e.g., rigid as in there is little, minimal or no relative movement between the sensor pod 12 and the vehicle 10). The rigidness resulting from the limiting or preventing of relative movement provides an anti-vibration system for the sensor pod 12 which, may reduce, limit, or prevent the negative impacts that vibration may cause on the sensor and/or the calibration of the sensors.

An opening 322, also referred to as a port 322, extends through the bracket 300. The opening 322 may extend from the side surface 314 through the bracket body 302 to an opposing surface 324, which is also referred to as a bracket face 324 (
Referring to
The bracket pin 318 provides a support axle extending from the bracket 300. The length of the support axle (e.g., the length of the bracket pin 318) and the depth of the respective opening 226 are sized (e.g., sized in length and diameter) to counteract the moment created by the weight of the sensor pod 12. This may allow for the sensor pod 12 to be easily, quickly, and efficiently installed and uninstalled. In some examples, this may be possible by a single operator. This is due to the load bearing hook that the bracket pin 318 provides, allowing a single person to lower the sensor pod 12 onto the bracket pin 318 which is already secured to the vehicle 10.
Referring to
The sensor pod arm 200c may have the upper side 202c and a lower side 204c formed to be weaker than a first lateral side 206c and a second lateral side 208c. The weaker sides form a crumple zone that allows the upper side 202c and the lower side 204c to fail, break, deteriorate, or bend, or combinations thereof, before the forward side 206c and the second lateral side 208c. The weaker upper side 202c and lower side 204c may be achieved through manufacturing, such as, for example, but limited to, weaker materials, machined or manufactured weak points, machined, or manufactured crumple zones, or combinations thereof. Weaker materials as described herein may be used in combination with any of the embodiments described and illustrated in this application.
As shown in
Any of the aforementioned connecting assemblies, or portions thereof, may be combined with other connecting assemblies without departing from the scope of the present disclosure.
With the structure of the connecting assembly 100 understood, installation, operation, and removal of the connecting assembly 100 is now set forth in
To install the sensor pod 12 on the vehicle 10 refers to the method or process of physically connecting the sensor pod 12 to the vehicle 10 by way of the connecting assembly 100 and physically connecting the one or more conduits extending from the vehicle 10 to the sensor pod 12. To uninstall or remove the sensor pod 12 from the vehicle 10 refers to the method or process of physically removing the sensor pod 12 from the vehicle 10 and physically disconnecting the one or more conduits from the sensor pod 12.
Briefly, to install the sensor pod 12 on the vehicle 10, the sensor pod arm 200 is located over the support axle (e.g., bracket pin 318) such that the opening 226 is aligned with the support axle. The sensor pod 12 and the sensor pod arm 200 are then lowered onto the support axle. Once lowered on, the support axle supports the weight of the sensor pod 12 and the sensor pod arm 200 in a manner that prevents the weight of the sensor pod 12 from causing the sensor pod 12 to fall once an operator is no longer supporting the sensor pod 12. The conduits are threaded through the opening 322 and the openings 214 on the connecting assembly 100 to be connected to the connection points. Once the conduits are connected, the sensor pod 12 may be secured to the bracket 300 with the fastener 230 and the fasteners 238. The connecting assembly 100, and in particular the support axle, allows for a single operator to install the sensor pod 12, even given the weight of the sensor pod 12 (e.g., the sensor pod 12 has significant weight due to the sensors and components therein, heavier than a conventional sideview mirror).
More specifically, to install the sensor pod 12 on a vehicle 10 (

At this point in the assembly, the connecting assembly 100 is secured in three directions. That is, the bracket 300 is fixedly secured to the sensor pod arm 200 and to the vehicle 10. The sensor pod 12 is prevented or limited in relative movement with respect to the bracket 300 and the vehicle 10 due to the connection. First, the connecting assembly 100 is secured against relative rotation in the direction 408 about the axis A1 such that the sensor pod 12 is secured against relative rotation with respect to the vehicle 10 (
Second, the connecting assembly 100 is secured against vertical movement in the direction 406 away from the bracket 300 such that the sensor pod 12 is secured against vertical movement with respect to the vehicle 10 (
Third, the connecting assembly 100 is secured against lateral movement in the direction 410 such that the sensor pod 12 is secured against lateral movement with respect to the vehicle 10 (
Continuing with assembly, and referring to
To remove the sensor pod 12 from the vehicle 10, a reverse procedure may be performed. That is, referring to
Referring again to
If desired, the bracket 300 may be removed from the vehicle 10 (
A method 600 of installing a sensor pod 12 is also set forth in
Accordingly, the connecting assembly 100 of the foregoing description provides a rigid and stable connection between the vehicle 10 and the sensor pod 12. The terms “rigid” and “stable” indicate that there is no relative motion between the sensor pod 12 and the vehicle 10 when the sensor pod 12 is affixed to the vehicle 10 with the connecting assembly 100. Thus, during operation of the vehicle 10, the sensor pod 12 will move in the same direction of travel as the vehicle 10. Such a rigid and stable connection allows for the sensor pod 12 to gather data and assist in navigation of the vehicle 10 with reduced or eliminated noise that is associated with relative motion of the sensor pod 12 with respect to the vehicle 10. As mentioned previously, the rigid connection provided by the connecting assembly 100 provides an anti-vibration system which results in the reduced or eliminated noise as there is minimal or no resonant vibration due to the sensor pod 12 moving with the vehicle 10. That is, the connecting assembly prevents or limits vibration of the sensor pod 12 with respect to the vehicle through the rigid connection of the connecting assembly 100, and in particular, due to the fixation points, as described previously. Reduction or prevention of vibration of the sensor pod 12 is important for the proper function of the sensor pod 12 and the sensors therein, which in turn is important to the proper operation of the vehicle 10. Vibration of the sensor pod 12 caused by an improperly or non-rigidly secured sensor pod 12 may affect the accuracy and precision of the sensors, which negatively impacts the operation of the sensor pod 12 and the vehicle 10.
With such a rigid connection, it is desirable to also provide the connecting assembly 100 with a design to minimize damage to the sensor pod 12, the vehicle 10, or other structures or vehicles that the vehicle 10 may contact, collide, or impact. That is, if the vehicle 10 collides with another object, which may be an inanimate or animate object, such as, for example, but not limited to, another vehicle, structure (e.g., building, lamppost, mailbox, etc.), or being (human or animals). The collision may be, for example, a head-on collision, sideswipe, etc. The collision may be caused by the vehicle 10 or the other object. In such collisions, the sensor pod 12 may be damaged, may damage the other object involved in the collision, or may damage the vehicle 10, or combinations thereof. If the connecting assembly 100 is maintained rigid during the entirety of the collision, the full force of the sensor pod may collide with the other object. Given the weight and size of the sensor pod 12, this may provide significant damage as previously noted.
In order to prevent, reduce, limit, eliminate, or otherwise mitigate the damage to the sensor pod, the vehicle 10, and/or the other object, the connecting assembly 100 is thus, designed to rigid during normal operating conditions (e.g., to provide no relative movement between the sensor pod 12 and the vehicle 10) as described previously, but also to weaken, fail, or flex at one or more predetermined points in the connecting assembly 100 such that relative movement of the sensor pod 12 is permitted with respect to the vehicle 10. In this situation, the sensor pod 12, when experiencing a predetermined force, may fold or flex inwards and rearwards toward the vehicle 10 (e.g., toward the vehicle doors).
The relative inward and rearward movement of the sensor pod 12 with respect to the vehicle 10 is achieved through the connecting assembly 100. The connecting assembly 100 is constructed to have a failure point at a predetermined force that allows the connecting assembly 100 to transition from the rigid construction discussed previously to a flexible construction which allows relative rotation of the sensor pod arm 200 with respect to the bracket 300 and the vehicle 10. The predetermined force is a force at which the connecting assembly transitions from the rigid construction to the flexible construction. In some examples, the predetermined force is the force at which the fasteners 238 (
Thus, when the sensor pod 12 is impacted with the predetermined force, the fasteners 238 (
Accordingly, the fasteners 238 (
Alternatives to a shear screw are contemplated to provide the transition from a rigid connecting assembly to a flexible connecting assembly. For example, a detent mechanism may be used. In some examples, the shear fastener 238 may be preferred. The sensor pod 12, with the sensors and hardware needed to support autonomous or semi-autonomous driving of the vehicle, are heavy. Indeed, the sensor pod 12, with the additional sensors and hardware, which may not be included on a conventional side view mirror, is comparatively heavier than the conventional side view mirror. A conventional side view mirror refers to a side view mirror that may include only mirrors and a housing and/or may include some sensors or cameras for assisting in side view or rear view, but does not include the additional sensors and hardware required to support autonomous driving (e.g., lidar and the like). Providing the shear fastener 238 assists in supporting the load of the sensor pod 12 and thus reduces vibrations experienced by the sensor pod 12 and assists in providing the rigid connection of the connecting assembly 100. Therefore, the fastener 238 is selected and/or designed to withstand the predetermined vibrational forces of the sensor pod 12, but also selected and/or designed to fail at a predetermined collision force that may act upon the sensor pod 12.
Furthermore, due to the removable connection between the sensor pod arm 200 and the bracket 300, the sensor pod 12 (whether involved in a collision or required to be updated, evaluated, repaired, or the like) may be removed for replacement, repairing, evaluation, etc. A new, different sensor pod 12 may be installed on the bracket 300 and/or the original sensor pod 12, once repaired, updated, or confirmed to be operational, may be installed on the bracket 300. Accordingly, the connecting assembly 100 provides a rigid connection, a flexible connection, and a removable connection. As long as the sensor pod 12 includes a sensor pod arm 200 that cooperates with and mates with the bracket 300 (e.g., with the side surface 314 and the bracket pin 318), any sensor pod 12 or other structure may be installed on the bracket 300.
As mentioned with respect to
Similarly, with respect to
Therefore, the connecting assembly of the present disclosure provides a rigid connection between a sensor pod and a vehicle during the normal operating conditions of the vehicle. Such a rigid connection prohibits, limits, reduces, or prevents relative motion between the sensor pod and the vehicle. The connecting assembly of the present disclosure further provides a flexible connection between the sensor pod and the vehicle when the sensor pod is acted upon by a predetermined force. The flexible connection allows relative movement between the sensor pod and the vehicle. Furthermore, the connecting assembly of the present disclosure provides a removable or detachable connection between the sensor pod and the vehicle 10 such that the sensor pod 12 may be easily and quickly removed, repaired, replaced, interchanged, or otherwise uninstalled and installed on the vehicle 10 at any location. That is, no relocation to a repair shop or manufacturing facility is required to install or uninstall the sensor pod.
Accordingly, the sensor pod of the present disclosure may be a quick swap sensor pod. That is, due to the connecting assembly, the sensor pod may be removed and installed on a vehicle in a quick manner by a single operator. In some examples, the sensor pod as a quick swap sensor pod includes a support axle. The support axle is formed to support the weight of the quick swap sensor pod before installation is complete (e.g., at a step of installation when the sensor pod is coupled to the bracket, but before the rigid connection is formed with the fasteners). The support axle may be formed with a depth, length, diameters, width, material, or combinations thereof to accomplish the support of the weight of the sensor pod. The support axle may also counteract a moment created by the weight of the sensor pod acting on the connecting assembly. That is, the weight of the sensor pod will provide a vertically downward force acting to rotate or bend the connecting assembly vertically downward. The support axle may counteract this bending moment, further achieving the aforementioned rigid connection which limits or prevents relative movement between the sensor pod and the vehicle.
In some examples, the support axle may be formed of the pin receiving opening and the pin. As discussed previously, the pin receiving opening may extend from one of the sensor pod arm or the bracket, with the pin extending from the other of the sensor pod arm or the bracket. The pin receiving opening may have a depth that correlates to a length of the pin. Both the depth of the pin receiving opening and the length of the pin are predetermined to counteract the bending moment and to support the weight of the quick swap sensor pod.
During installation of the quick swap sensor pod, the quick swap sensor pod is moved between an initial position (e.g.,
In some examples of the quick swap sensor pod, the depth of the pin receiving opening and/or the length of the pin is further selected to allow installation of the quick swap sensor pod by a single operator. Furthermore, the lower surface of the protrusion extending from the sensor pod arm rests on an upper surface of the protrusion of the bracket to support the weight of the quick swap sensor pod. Additionally, the length of the pin is selected to counteract a moment created by a weight of the quick swap sensor pod and the upper surface of the protrusion extending from the bracket is configured to support the weight of the quick swap sensor pod.
With the above configurations, the quick swap sensor pod may be installed and removed a plurality of times. The quick swap sensor pod may have a common arm that interacts with the bracket arm but may have a housing with different configurations of mirrors, sensors, or the like. In this manner, the quick swap sensor pod may be interchangeable with other quick swap sensor pods of the same or different configurations. Furthermore, in the event the quick swap sensor pod is needed to be removed due to damage, need for repair, need for calibration, software updating, hardware updating, etc., the quick swap sensor pod may be removed and reinstalled or removed and replaced with another quick swap sensor pod.
In some examples of the quick swap sensor pod, the support axle extends vertically between the sensor pod and the bracket. The quick swap sensor pod and the sensor pod arm rotate about the support axle and with respect to the bracket between the initial position and the final position, in the manner previously described. In both the initial position and the final position, a length of the support axle is selected to counteract a moment created by a weight of the quick swap sensor pod and to support the weight of the quick swap sensor pod. The support axle may extend from the sensor pod arm, the bracket, or both the sensor pod arm and the bracket. The support axle may include the pin receiving opening and the pin for installation in the pin receiving opening. As mentioned, the pin receiving opening may extend from the sensor pod arm and the pin may extend from the bracket. In another example, the pin receiving opening may extend from the bracket and the pin may extend from the sensor pod arm. The length of the support axle is further selected to allow installation of the quick swap sensor pod by a single operator and/or may allow installation and removal a plurality of times.
The connecting assembly of the present disclosure allows for connection of sensors within the sensor pod to be connected to the vehicle via one or more conduits. The conduits are connected to a conduit connector (e.g., 222 of
In some examples, the conduits may extend from the vehicle with extra length than is needed to reach from the vehicle to the conduit connector. This extra length is a slack length of the conduit. The extra length permits the conduits to be connected to the connection point in the pivoted position of
As mentioned previously, there may be a plurality of conduits and conduit connectors. Each connection of the conduit with the conduit connector forms a conduit connector point. A conduit may be a fluid conduit, such as a water conduit or air conduit, or may be an electrical conduit, allowing power and data signals to transfer therethrough.
The conduits may have connections for coupling to the conduit connectors in the sensor pod that are designed to interact with any number of sensor pods. In this manner, the sensor pods may be interchanged on the vehicle without having to remove and replace the conduits.
As discussed previously, a predetermined force, referred to interchangeably as a predetermined collision force, acting on the sensor pod may cause the connecting assembly to change from a rigid connection to a flexible connection. The predetermined force may be selected based on force simulations. The predetermined force may be a force that directly impacts the sensor pod. Small forces (e.g., forces below the predetermined force) on the sensor pod, such as, for example, but not limited to forces caused by normal operating conditions (e.g., rocks kicked up during road travel), may not affect the rigidness of the connecting assembly. That is, these forces may be below the predetermined force to shear the fasteners (or cause the crumple or spring compression).
The connecting assembly, or any part or combination of parts thereof, may be formed of metal, such as, for example, aluminum, composites, such as, for example, fiber glass, carbon fiber, or other known materials, or combinations thereof. The connecting assembly, or any part or combination of parts thereof, may be formed by casting, machining, molding, or other known manufacturing methods, or combinations thereof. The bracket arm pin may be formed of a chrome plated hardened steel or other known materials for providing a bearing surface.
The connecting assembly of the present disclosure provides both a rigid connection and a flexible connection between a sensor pod and a vehicle. The connecting assembly allows for a rigid assembly between the parts during the normal operation of the vehicle such that there is little or no relative movement between the sensor pod and the vehicle. If the sensor pod experiences a predetermined collision force, the connecting assembly becomes a flexible connection, allowing the sensor pod to move with respect to the vehicle out of the way of further collision, reducing damage or harm to the sensor pod, the vehicle, or the other object to the collision and reducing the amount of debris on the road caused by the collision. The connecting assembly of the present disclosure also provides a universal connection point that allows for a multitude of types of sensor pods to be installed, removed, or interchanged, etc. with the vehicle in a quick and efficient process that may occur anywhere, including outside of a manufacturing facility or repair shop.
The connecting assembly of the present disclosure further allows for a quick swap sensor pod and a universal bracket such that a multitude of sensor pods may be interchanged on the vehicle quickly and efficiently. The connecting assembly may allow for a rigid connection during operation that operates as an anti-vibration system to reduce extraneous vibration and noise to the sensor pod. The structure of the connecting assembly may support the weight of the sensor pod and counteract the moment acting on the connecting assembly by the weight of the sensor pod.
According to embodiments of the present disclosure, a sensor pod is connected to the truck frame with a universal bracket. The universal bracket has a planar face having at least three fixation points generally perpendicular to face. A port extends through the planar face for passing leads. The universal bracket includes a connecting mechanism to the sensor pod. The sensor pod has an arm extending from bracket, a housing supporting a plurality of sensors, and a plurality of lead connectors in the arm. The planar face is configured to connect to any one of a plurality of truck frames and the connecting mechanism is configured to connect to any one of a plurality of sensor pods.
According to embodiments of the present disclosure, a quick swap sensor pod for a truck includes an arm, a face on the arm having a post receiving hole having a depth and aligned vertically. The post receiving hole has enough depth for the hole to counteract a moment from the weight of the sensor pod at a distance of the arm and also to easily rotate sensor pod about the post receiving hole. The arm includes enough surface on the face to support the weight of the sensor pod and also to easily rotate the sensor pod about the post receiving hole. The quick swap sensor pod includes a connecting mechanism in the arm for connecting leads while the arm is at a first rotation angle. The quick swap sensor pod includes fixation holes aligned to affix the connecting mechanism.
According to embodiments of the present disclosure, an apparatus for reducing damage and debris from a hit to a sensor pod includes a bracket having a post for rotation of the sensor pod around post, an axle bolt to fix the sensor pod from backing off post, and a second frangible fixation point set away from the post configured to break apart when the sensor pod is struck with a force that would otherwise damage the sensor pod. According to embodiments of the present disclosure, a method for reducing damage includes a fixing step to stop backing off post, a rotating step to align second fixation alignment, and a tightening step to tighten a second fixation to a load less than is tension strength.
According to embodiments of the present disclosure, an apparatus for connecting sensors in a sensor pod to a truck includes connectors located on a sensor housing having a first shear strength when the connector is in tension, leads extending from the connectors to the truck having a second shear strength when the leads are in tension, the leads additionally having slack in their length. The first shear strength is less than second shear strength.
