This application is based on and claims priority to CN application No. 201811510502.3, filed on Dec. 11, 2018, the disclosure of which is hereby incorporated by reference in its entirety.
The present disclosure relates to the field of logistics and delivery technology, in particular to an unmanned vehicle chassis and an unmanned vehicle.
To adapt to different cargo quantities and cargo volumes, an unmanned delivery vehicle usually needs to be equipped with cargo boxes of different sizes. The cargo boxes need to be carried by chassis, so chassis of different sizes need to be designed and developed for the cargo boxes of different sizes. The cost of developing and manufacturing chassis of different sizes is relatively high.
An object of the present disclosure is providing an unmanned vehicle chassis and an unmanned vehicle to meet the requirement or carrying cargo boxes or different sizes.
A first aspect of the present disclosure provides an unmanned vehicle chassis, which includes at least two chassis units, the at least two chassis units being spliced to form the unmanned vehicle chassis.
In some embodiments, the unmanned vehicle chassis includes at least two different chassis units.
In some embodiments, the at least two chassis units are spliced in a horizontal direction.
In some embodiments, the chassis unit includes a chassis unit body and wheels arranged on the underside of the chassis unit body.
In some embodiments, the chassis unit body has connecting surfaces configured to connect with adjacent other chassis unit bodies; and the chassis unit further includes connecting portions provided on the connecting surfaces of the chassis unit body, and the connecting portions are configured to connect adjacent two chassis unit bodies.
In some embodiments, the connecting portions include magnetic bodies.
In some embodiments, the connecting surfaces include protrusions located on two ends thereof respectively, and magnetic bodies are attached to the protrusions.
In some embodiments, the unmanned vehicle chassis includes a controller, which is coupled with the at least two chassis units to control the at least two chassis units to move synchronously.
In some embodiments, the chassis unit includes a communication module and a control module, the communication module being configured to receive a control signal from the controller and transmit the signal to the control module.
In some embodiments, the chassis unit includes wheels, a driving motor configured to drive the wheels to travel, and a steering motor configured to control the steering of the wheels, and the control module is configured to control operation of the driving motor and the steering motor.
A second aspect of the present disclosure provides an unmanned vehicle, which includes the unmanned vehicle chassis of any paragraph of the first aspect of the present disclosure.
In some embodiments, the unmanned vehicle includes a sensor assembly and a controller, the sensor assembly being configured to monitor the surrounding environment, the controller being configured to receive monitoring information sent by the sensor assembly and control movement of the unmanned vehicle chassis according to the monitoring information.
In some embodiments, the unmanned vehicle further includes a cargo box provided on the unmanned vehicle chassis, and the unmanned vehicle chassis formed by splicing at least two chassis units is matched in size to the cargo box.
Based on the technical solution provided in the present disclosure, the unmanned vehicle chassis includes at least two chassis units, the at least two chassis units being spliced to form the unmanned vehicle chassis. The unmanned vehicle chassis of the present disclosure is formed by splicing at least two chassis units, so unmanned vehicle chassis of different sizes can be formed by splicing different numbers of chassis units to carry cargo boxes of different sizes, without the need to specially design and develop different chassis for cargo boxes of different sizes, thereby reducing the research and development cost.
Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings.
Drawings described here are used to provide a further understanding of the present disclosure and form a part of the present application. Illustrative embodiments of the present disclosure and description thereof are used for explaining the present disclosure, but do not improperly limit the present disclosure. In the drawings:
Technical solutions in the embodiments will be described below clearly and completely in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative, and in no way serves as any limitation to the present disclosure and its application or use. Based on the embodiments in the present disclosure, all of other embodiments obtained by a person of ordinary skill in the art without creative work should fall into the protection scope of the present disclosure.
Unless specifically stated otherwise, the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure. Furthermore, it should be understood that, for ease of description, the sizes of various parts shown in the drawings are not drawn in accordance with actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the related art may be not discussed in detail, but where appropriate, the technologies, methods, and device should be regarded as part of the specification as granted. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of an exemplary embodiment may have different values. It should be noted that similar reference numerals and letters denote similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
For ease of description, spatially relative terms such as “above . . . ”, “over . . . ”, “on an upper surface of . . . ” and “upper” may be used here to describe spatial positional relationship between one device or feature and other devices or features as shown in the figures. It should be understood that a spatially relative term is intended to encompass different orientations in use or operation other than the orientation of a device described in a figure. For example, if the device in the figure is inverted, then the device described as “above other devices or structures” or “over other devices or structures” will be positioned “below other devices or structures” or “under other devices or structures”. Thus, the exemplary term “above . . . ” may include both orientations of “above . . . ” and “below . . . ”. The device may also be positioned in other different ways (rotated by 90 degrees or in other orientations), and the relative spatial description used here is explained accordingly.
