This application is based on and claims priority to and benefits of Chinese Patent Applications No. 202311285539.1, 202322663835.2 and 202322681460.2, filed on Sep. 28, 2023. The entire contents of the aforementioned patent documents are incorporated by reference for all purposes.
The present disclosure relates to the field of vehicles, and specifically relate to a step device and a vehicle having the same.
It is inconvenient for people to enter and exit vehicles with large ground clearances, such as off-road vehicles and buses. Therefore, steps are usually mounted on the vehicles to facilitate people to step thereon so as to enter and exit the vehicles. However, the traditional step still has the problem of poor practical convenience. For example, for vehicles with large ground clearances, the height of the traditional step is too low or too high, which affects the convenience of use and applicability to different vehicles.
In some aspects, a step device for a vehicle according to some embodiments of a first aspect of the present technology includes a mounting frame; a fixed step mounted on the mounting frame; a retractable mechanism mounted to one of the mounting frame and the fixed step; and a retractable step mounted on the retractable mechanism so that the retractable mechanism drives the retractable step to move between an extended position and a retracted position. In the extended position, at least a part of the retractable step extends outward beyond the fixed step from underneath the fixed step so that the retractable step and the fixed step form two steps; and, in the retracted position, the retractable step retracts to a position underneath the fixed step.
The step device for a vehicle according to some embodiments of the present technology has the advantages having a compact structure, providing an improved convenience for a user to embark and disembark to/from a high-clearance vehicle using the step device, a low level of difficulty to mount and detach from the vehicle (e.g., installation), and a high level of efficiency when mounting and detaching, and being highly applicable to a wide variety of vehicles, particularly those with large ground clearance heights (e.g., ground to floor of vehicle interior).
In some aspects, a vehicle according to some embodiments of a second aspect of the disclosed technology includes a vehicle body, a vehicle door, and a step device of the present technology. In some embodiments of the step device, the mounting frame of the step device can be mounted on the vehicle body.
The vehicle according to the embodiments of the present disclosure has the advantages of a low assembly and disassembly difficulty and a high assembly and disassembly efficiency.
Hereinafter, embodiments of the present disclosure will be described in detail, and examples of the embodiments are illustrated in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are illustrative and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.
For convenience of description, in the description of the embodiments of the present disclosure, a front-rear direction refers to a front-rear direction of a vehicle after a step is mounted on a vehicle body. After the step is mounted on the vehicle body, a direction toward the inside of the vehicle body is inward and a direction toward the outside of the vehicle body is outward.
Presently, for existing vehicle step devices, the step device that is mounted on the vehicle is usually fixed, and the height of the fixed step from the ground is fixed, so that the applicability and convenience are poor. Moreover, for conventional vehicle step devices, it is typically required to install a retractable step on the vehicle. When in use, the retractable step extends from underneath the vehicle, and when not in use, the retractable step retracts to a position underneath the vehicle.
However, for a vehicle with a large ground clearance (between the ground and the floor of the vehicle), the fixed step and the retractable step may have the problems of high height and inconvenience of use, particularly for shorter individuals, elderly, and/or children to embark and disembark from the vehicle. Therefore, it is proposed to provide a vehicle step apparatus with a fixed step and the retractable step to be mounted on the vehicle, so that the retractable step forms a second step with the fixed step for the vehicle step apparatus when extended outward, thus improving the convenience and safety of use and the applicability for different vehicles.
However, for existing vehicle step devices in the related art, either a fixed step and a retractable step is mounted under the vehicle, lacking ability to accommodate high ground clearance and/or different heights and stepping abilities of various users to easily and conveniently get in and out of the vehicle. Moreover, having the fixed step and the retractable step respectively mounted under the vehicle, leads to a complicated mounting structure and a time-consuming and laborious assembly (and disassembly) for installation and/or repair. Moreover, due to the limited space under a chassis of the vehicle, both mounting difficulties and operation difficulties of the fixed step and the retractable step are further increased. In addition, in such conventional vehicle step devices, the retractable step is located completely under the vehicle in a retracted position, which will adversely affect the trafficability of the vehicle.
In addition, in the related art, the number of the retractable steps mounted on the vehicle is determined in advance, and a control system for the retractable steps has a number of interfaces equal to the number of the retractable steps. When the user wants to increase the number of the retractable steps (for example, when a user wants to add the retractable step at the tailgate of the vehicle), the whole control system needs to be replaced, resulting in a high cost, an inconvenient refitting, and a poor user experience.
The present technology solves at least some of the above technical problems to some extent.
As shown in
The retractable mechanism 12 is mounted on one of the mounting frame 51 and the fixed step 31, and the retractable step 11 is mounted on the retractable mechanism 12 so that the retractable mechanism 12 drives the retractable step 11 to move between an extended position and a retracted position. At the extended position, at least a part of the retractable step 11 extends outward beyond the fixed step 31 from underneath the fixed step 31, so that the retractable step 11 and the fixed step 31 form two steps. In the retracted position, the retractable step 11 is retracted to a position underneath the fixed step 31.
According to some embodiments of the step device 10, by mounting both the fixed step 31 and the retractable mechanism 12 on the mounting frame 51 or by mounting the retractable mechanism 12 on the fixed step 31 and mounting the fixed step 31 on the mounting frame 51, the step device 10 can be assembled into a whole, so that the step device 10 can be mounted or detached simply by mounting the mounting frame 51 to a vehicle body 21 or detaching the mounting frame 51 from the vehicle body 21.
That is, before mounting the step device 10 to the vehicle body 21 of the vehicle 1, the fixed step 31, the retractable step 11, the retractable mechanism 12 and the mounting frame 51 can be assembled together. Therefore, it is possible to reduce the difficulties of mounting the step device 10 to the vehicle body 21 and detaching the step device 10 from the vehicle body 21, thus improving the efficiency of mounting the step device 10 to the vehicle body 21 and detaching the step device 10 from the vehicle body 21.
Moreover, by retracting the whole or at least most of the retractable step 11 to be below the fixed step 31 without retracting it to be below the vehicle body 21 or at least without retracting the whole retractable step 11 to be below the vehicle body 21, the space between the chassis of the vehicle 1 and the ground will not be significantly occupied, so that the distance between the chassis of the vehicle 1 and the ground is ensured, thereby ensuring the trafficability of the vehicle 1. In the extended position, the fixed step and the retractable step form multi-stage steps, which is especially beneficial for a vehicle with high ground clearance, thus providing a good applicability and a wide application range.
Therefore, the step device 10 of the embodiments of the present disclosure has the advantages of a compact structure, a low mounting and detaching difficulty, a high mounting and detaching efficiency, and the like.
As shown in
The step device 10 includes a mounting frame 51, a fixed step 31, a retractable step 11, and a retractable mechanism 12. The mounting frame 51 may be mounted to the vehicle body 21.

That is, the first side plate 511 and the second side plate 512 are connected together by each of the outer beam 513, the inner beam 514 and the middle beam 515.
The inner beam 514 is located on an inner side of the outer beam 513, and the middle beam 515 is located between the inner beam 514 and the outer beam 513. The fixed step 31 is connected with the outer beam 513 and the middle beam 515 through a connector, and the retractable mechanism 12 is connected with the inner beam 514 and the outer beam 513 through a connector. Thus, the fixed step 31 and the retractable mechanism 12 can be more stably mounted on the mounting frame 51.
The inner beam 514 is an inner transverse plate lying horizontally. That is, the inner beam 514 is generally plate-shaped, and the inner beam 514 is horizontally arranged, i.e., a thickness direction of the inner beam 514 is consistent with an up-down direction.
The outer beam 513 includes a first outer transverse plate 5131 lying horizontally and a second outer transverse plate 5132 standing vertically. In other words, each of the first outer transverse plate 5131 and the second outer transverse plate 5132 is generally plate-shaped, the first outer transverse plate 5131 is horizontally arranged, i.e., a thickness direction of the first outer transverse plate 5131 is consistent with the up-down direction, and the second outer transverse plate 5132 is vertically arranged, i.e., the thickness direction of the second outer transverse plate 5132 is consistent with a horizontal direction. An upper edge of the second outer transverse plate 5132 is connected with the first outer transverse plate 5131.
The middle beam 515 includes a first middle transverse plate 5151 standing vertically and a second middle transverse plate 5152 standing vertically. That is, each of the first middle transverse plate 5151 and the second middle transverse plate 5152 is generally plate-shaped, and both of them are vertically arranged, i.e., a thickness direction of the first middle transverse plate 5151 is consistent with the horizontal direction, and a thickness direction of the second middle transverse plate 5152 is consistent with the horizontal direction. The first middle transverse plate 5151 and the second middle transverse plate 5152 are arranged at intervals in an inner-outer direction.
The fixed step 31 is connected with the first outer transverse plate 5131 and the first middle transverse plate 5151, and the retractable mechanism 12 is connected with the inner transverse plate (the inner beam 514) and the second outer transverse plate 5132. The lower surface of the inner transverse plate is higher than the upper surface of the first outer transverse plate 5131. The connection position between the fixed step 31 and the first middle transverse plate 5151 and the second middle transverse plate is higher than the upper surface of the first outer transverse plate 5131. Therefore, the structures of the mounting frame 51 and the step device 10 can be more easily made.

A first end of the first horizontal plate 1211 is connected with the third side plate 1213, a second end of the first horizontal plate 1211 is connected with the fourth side plate 1214, a first end of the first vertical plate 1212 is connected with the third side plate 1213, and a second end of the first vertical plate 1212 is connected with the fourth side plate 1214. That is, the third side plate 1213 and the fourth side plate 1214 are connected together by each of the first horizontal plate 1211 and the first vertical plate 1212.
The first horizontal plate 1211 and the inner beam 514 are connected by a bolt. Specifically, the first horizontal plate 1211 has a first through hole, and the inner beam 514 has a second through hole, and the bolt passes through the first through hole and the second through hole to connect the first horizontal plate 1211 with the inner beam 514.
The first vertical plate 1212 and the second outer transverse plate 5132 are connected by a bolt. Specifically, the first vertical plate 1212 has two third through holes, and the second outer transverse plate 5132 has two fourth through holes. One bolt passes through one of the third through holes and one of the fourth through holes to connect the first vertical plate 1212 with the second outer transverse plate 5132, and the other bolt passes through the other third through hole and the other fourth through hole to connect the first vertical plate 1212 with the second outer transverse plate 5132.
In some embodiments, the distance between the one of the third through holes and the third side plate 1213 in the length direction of the fixed step 31 is approximately equal to the distance between the other third through hole and the fourth side plate 1214 in the length direction of the fixed step 31. For example, the third side plate 1213 and the fourth side plate 1214 are symmetrically arranged with respect to a first straight line (a first vertical plane), and the two third through holes are also symmetrically arranged with respect to the first straight line (the first vertical plane).
One of the fourth through holes is adjacent to the first side plate 511 in the length direction of the fixed step 31, and the distance between the other fourth through hole and the first side plate 511 in the length direction of the fixed step 31 is approximately equal to the distance between the other fourth through hole and the second side plate 512 in the length direction of the fixed step 31. That is, the other fourth through hole is located in the middle of the first side plate 511 and the second side plate 512.

A length direction of the inner tube 3131 coincides with the length direction of the vehicle body 21, and a length direction of the outer tube 3132 coincides with the length direction of the vehicle body 21. There are a plurality of reinforcing tubes 3134, which are arranged at intervals along the length direction of the inner tube 3131 (the outer tube 3132). An inner end of each reinforcing tube 3134 is connected with the inner tube 3131, and an outer end of each reinforcing tube 3134 is connected with the outer tube 3132.

In some embodiments, in the retracted position, at least a part of the surface of the retractable step 11 is flush with the surface of the fixed step 31. Therefore, the accommodating groove 311 can better protect the retractable step 11, further prolonging the service life of the retractable step 11 and the step device 10 and making the structure of the step device 10 more compact.
A bottom surface of the fixed step 31 includes a first inclined surface portion 3122 that is inclined downward from outside to inside, and a bottom surface 111 of the retractable step 11 includes a first flat surface portion 1111 that is horizontal at the extended position and a second inclined surface portion 1112 that is inclined downward from outside to inside. In other words, the bottom surface 111 of the retractable step 11 includes the first flat surface portion 1111 and the second inclined surface portion 1112. The first flat surface portion 1111 of the retractable step 11 at the extended position is located on a horizontal plane, that is, the first flat surface portion 1111 of the retractable step 11 in the extended position is horizontally arranged, and the second inclined surface portion 1112 of the retractable step 11 in the extended position is obliquely arranged. When the retractable step 11 is in the extended position, an inner edge of the second inclined surface portion 1112 is connected with an outer edge of the first flat surface portion 1111, and the inner edge of the second inclined surface portion 1112 is located below an outer edge of the second inclined surface portion 1112.
In the retracted position, the second inclined surface portion 1112 is flush with the first inclined surface portion 3122, and an outer side surface 112 of the retractable step 11 is opposite an outer side wall surface 3111 of the accommodating groove 311. Therefore, the accommodating groove 311 can better protect the retractable step 11 and further prolong the service life of the retractable step 11 and the step device 10.
In some embodiments, in the retracted position, a gap between the outer side surface 112 of the retractable step 11 and the outer side wall surface 3111 of the accommodating groove 311 is greater than or equal to zero and less than or equal to 5 mm. Therefore, the external foreign matter such as sand and gravel can be further prevented from entering the accommodating groove 311, that is, the external foreign matter such as sand and gravel can be further prevented from entering to be between the fixed step 31 and the retractable step 11 located in the retracted position, so that the retractable step 11 can be better protected, and the service life of the retractable step 11 and the step device 10 can be further improved.
Each retractable step 11 is mounted on a corresponding retractable mechanism 12. The step device 10 further includes a motor 13, which is connected with the corresponding retractable mechanism 12, and the motor 13 is used for driving the corresponding retractable mechanism 12 to drive the corresponding retractable step 11 to move between the extended position and the retracted position.
In some embodiments, the motor 13 is a brushless motor. The brushless motor has the advantages of a small size, a simple control program, an accurate position and a speed control of the retractable step 11, and a small impact, and can stop the retractable step 11 at any position between the extended position and the retracted position.
In some embodiments, the whole of the fixed step 31 is located at an outer side of the vehicle body 21. Or, a distance between an innermost point of the fixed step 31 and an outer side surface of the vehicle body 21 is less than 20 mm, that is, the distance between the innermost point of the fixed step 31 and the outer side of the vehicle body 21 in the inner-outer direction is less than 20 mm. Therefore, the whole or most of the fixed step 31 can be located at the outer side of the vehicle body 21, so that it is convenient for the user to get on (enter) and get off (exit) the vehicle by stepping on the fixed step 31, and thus the user can enter and exit the vehicle more easily.
In some embodiments, in the retracted position, the whole of the retractable step 11 is located on the outer side of the vehicle body 21. Or, a distance between an innermost point of the retractable step 11 and the outer side surface of the vehicle body 21 is less than 30 mm, that is, the distance between the innermost point of the retractable step 11 and the outer side surface of the vehicle body 21 in the inner-outer direction is less than 30 mm. Therefore, when the retractable step 11 moves from the retracted position to the extended position, the retractable step 11 can be extended from the vehicle body 21 by a large distance, so that it is convenient for the user to enter and exit the vehicle by stepping on the retractable step 11, and thus the user can enter and exit the vehicle more easily.
In some example embodiments, the step device 10 further includes a controller 14 having a plurality of interfaces 141. The retractable step device includes at least one retractable step 11, and each retractable step 11 is mounted on a corresponding retractable mechanism 12. The motor 13 has a one-to-one correspondence with the retractable mechanism 12. Each motor 13 is connected with a corresponding retractable mechanism 12 to drive the corresponding retractable mechanism 12 to drive the corresponding retractable step 11 to move between the extended position and the retracted position. In other words, the motor 13 can drive the retractable step 11 mounted on the retractable mechanism 12 to extend and retract through the corresponding retractable mechanism 12. The number of the interfaces 141 is greater than that of the retractable steps 11, and one motor 13 driving one retractable mechanism 12 corresponding to each retractable step 11 is connected to one interface 141.
In some example embodiments, the step device 10 further includes a controller 14 having a plurality of interfaces 141. The retractable step device includes at least one retractable step 11, and each retractable step 11 is mounted on at least one of a plurality of corresponding retractable mechanisms 12. The motor 13 has a one-to-one correspondence with the retractable mechanism 12. Each motor 13 is connected with the corresponding retractable mechanism 12 to drive the corresponding retractable mechanism 12 to drive the corresponding retractable step 11 to move between the extended position and the retracted position. In other words, the motor 13 can drive the retractable step 11 mounted on the retractable mechanism 12 to extend and retract through the corresponding retractable mechanism 12. The number of the interfaces 141 is greater than that of the retractable steps 11, and a plurality of motors 13 driving a plurality of retractable mechanisms 12 corresponding to the same retractable step 11 are connected to the same interface 141.
According to some example embodiments of the step device of the present technology, a controller with the plurality of interfaces is arranged, and the number of the interfaces is greater than the number of the retractable steps, so that at least one retractable step can be controlled only by using only one controller. Therefore, the cost of the controller and the step device can be reduced, the diversity of mounting positions of the controller can be saved, the difficulty of installing and mounting the controller can be reduced, and the integration of the step device can be improved.
Since the number of the interfaces is greater than the number of the retractable steps, even if the user adds the retractable steps later, there is no need to arrange new controllers. That is to say, the controller has a reserved interface to connect the motor driving the additional retractable steps, thus enabling the user to change the number of the retractable steps as required. Moreover, when the step device is used in different vehicle models, the user can increase or decrease the number of the retractable steps according to the vehicle models, without additionally arranging new controllers or detaching the controllers already arranged.
In the present disclosure, “the number of the interfaces is greater than the number of the retractable steps” means that the number of the interfaces of the controller is greater than the number of the initial retractable steps of the step device, so that the redundant interfaces can be used as reserved interfaces, and thus the number of the retractable steps of the step device can be expanded. It can be understood that the number of the interfaces can be equal to the number of retractable steps after the number of the retractable steps is subsequently expanded. For example, when the step device is sold in the factory or mounted on the vehicle by a vehicle manufacturer, two retractable steps are provided, and the controller has three interfaces, one of which is used as the reserved interface. When the user or the vehicle manufacturer expands the number of the retractable steps of the step device to three according to the customer's requirements, the motor driving the added retractable step is connected with the reserved interface. The specific difference in value between the number of the interfaces and the number of the retractable steps can be set according to specific needs. In some embodiments, the number of the interfaces is set to be greater than or equal to the maximum number of the retractable steps that can be mounted to the vehicle.
Therefore, the step device of the embodiments of the present disclosure has the advantages of a low cost, a low mounting difficulty, a high integration, a wide application range, and suitability for various vehicle models.
In some embodiments, the fixed step 31 has a plurality of mounting positions, and the number of the mounting positions is greater than that of the retractable mechanisms 12, that is, the number of the mounting positions is greater than that of the retractable steps 11. Therefore, the fixed step 31 has a reserved mounting position, so that it is more convenient to add the retractable mechanism 12 and the retractable step 11.
Each retractable step 11 is mounted on a corresponding retractable mechanism 12. As shown in

In some embodiments, the step device 10 further includes an extension and retraction control switch (not shown), and the controller 14 allows or prohibits the retractable step 11 from moving between the extended position and the retracted position according to a switching position of the extension and retraction control switch.
The extension and retraction control switch has a plurality of switching positions, and the controller 14 allows the retractable steps 11 whose number corresponds to the switching position to move between the extended position and the retracted position according to the switching position of the extension and retraction control switch.
For example, the vehicle 1 has a left door, a right door and a tailgate. When the extension and retraction control switch is in a 0 switching position, all the retractable steps 11 are prohibited from moving. When the extension and retraction control switch is in a 1 switching position, only the retractable step 11 corresponding to the left door is allowed to move. When the extension and retraction control switch is in a 2 switching position, only the retractable steps 11 corresponding to the left door and the right door are allowed to move. When the extension and retraction control switch is in a 3 switching position, the retractable steps 11 corresponding to the left door, the right door and the tailgate are allowed to move.
For example, the vehicle 1 has a left front door 221, a left rear door 222, a right front door, a right rear door and a tailgate. The extension and retraction control switch can have four switching positions. When the extension and retraction control switch is in a 0 switching position, all the retractable steps 11 are prohibited from moving. When the extension and retraction control switch is in a 1 switching position, only the retractable step 11 corresponding to the left front door 221 and the retractable step 11 corresponding to the left rear door 222 are allowed to move. When the extension and retraction control switch is in a 2 switching position, only the retractable step 11 corresponding to the right front door and the retractable step 11 corresponding to the right rear door are allowed to move. When the extension and retraction control switch is in a 3 switching position, the retractable steps 11 corresponding to the left front door 221, the left rear door 222, the right front door, the right rear door and the tailgate are allowed to move.
The extension and retraction control switch can also have six switching positions. When the extension and retraction control switch is in a 0 switching position, all retractable steps 11 are prohibited from moving. When the extension and retraction control switch is in a 1 switching position, only the retractable step 11 corresponding to the left front door 221 is allowed to move. When the extension and retraction control switch is in a 2 switching position, only the retractable step 11 corresponding to the left front door 221 and the retractable step 11 corresponding to the left rear door 222 are allowed to move. When the extension and retraction control switch is in a 3 switching position, only the retractable steps 11 corresponding to the left front door 221, the left rear door 222 and the right front door are allowed to move.

Of course, the step device 10 and the vehicle 1 of the embodiments of the present disclosure are not limited to the above control modes, and the corresponding control modes can be selected according to the habits of the user.
In some embodiments, there are a plurality of retractable steps 11, and the plurality of retractable steps 11 can move between the extended position and the retracted position independently of each other. Therefore, it is only necessary to extend and retract the retractable step 11 corresponding to the door where a user enters or exits the vehicle, so that the structure of the step device 10 can be more convenient.
In some embodiments, the vehicle door includes a left door and a right door, and the step device includes a left step device mounted on the left side of the vehicle body 21 and a right step device mounted on the right side of the vehicle body 21. Either one of the retractable steps 11 of the left step device and the retractable steps 11 of the right step device can independently move between the extended position and the retracted position.
