Description

Technical Field

[0001] The present disclosure relates to the field of vehicle technology, and in particular to a chassis, a vehicle and a car-changing device. Background Art

[0002] With the continuous development of urban planning, urban functional sectors are continuously centralized and functionalized. The daily maintenance and services of various functional parks in the city mainly include three main aspects: transportation services, logistics services, and cleaning services. Considering that the park area is usually large, the above services usually need to be equipped with corresponding vehicles. Different vehicles need to have different structures on the carriage to meet different service needs. For example, to meet the cleaning requirements, it is necessary to connect water tanks and nozzles to the carriage. In related technologies, the vehicle chassis and the carriage are fixedly connected, which makes it impossible to quickly replace the carriage. Therefore, in order to meet the above three different services, it is usually necessary to pair three corresponding vehicles, resulting in high vehicle procurement and subsequent maintenance costs.

DETAILED DESCRIPTION

[0035] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, directional words such as "horizontal, longitudinal, vertical" are used based on Figure 1 The XYZ coordinate system in the specification is defined, specifically, the X direction refers to the horizontal direction, the Y direction refers to the longitudinal direction, and the Z direction refers to the vertical direction, and corresponds to the up and down directions, and the side indicated by the arrow is the upper side, and the opposite is the lower side. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element, and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.

[0037] In an exemplary embodiment of the present disclosure, a chassis is provided, referring to Figures 1 to 5As shown, the chassis includes a chassis body 1, a conveying structure 2 and a locking mechanism 4 arranged on the chassis body 1. A mounting groove 11 extending longitudinally is provided on the chassis body 1. The chassis body 1 is used for sliding connection with the carriage 3 through the mounting groove 11. The conveying structure 2 is used for driving the carriage 3 to slide along the mounting groove 11. The locking mechanism 4 is used for selectively locking the chassis body 1 and the carriage 3 together.

[0038] Through the above technical solution, different functional requirements of the vehicle can be met by setting different carriages 3. For example, by replacing the carriage 3 configured as a passenger compartment 32 on the chassis, the passenger carrying function of the vehicle can be realized, by replacing the carriage 3 configured as a cargo compartment 33 on the chassis, the cargo transportation function of the vehicle can be realized, and by replacing the carriage 3 configured as a cleaning compartment 34 on the chassis, the environmental cleaning function of the vehicle can be realized. Specifically, when the carriage 3 needs to be replaced, the locking connection between the chassis body 1 and the carriage 3 is released by the locking mechanism 4, and then the conveying structure 2 drives the carriage 3 to slide along the installation groove 11 to one side in the longitudinal direction, so that the original carriage 3 is separated from the chassis body 1, and the original carriage 3 is disassembled. Then the conveying structure 2 drives the new carriage 3 to slide along the installation groove 11 to the other side in the longitudinal direction. Finally, the locking connection between the chassis body 1 and the carriage 3 is realized by the locking mechanism 4, and the assembly of the new carriage 3 and the chassis is realized. At this time, the carriage 3 and the chassis are fixed together by the locking mechanism 4, so the stability of the vehicle is better. In this way, the chassis of the present invention can be detachably connected to the carriage 3, and the carriage 3 can be quickly replaced. Therefore, when the chassis of the present invention is actually used, different functions of the vehicle can be realized by replacing different types of carriages 3. Therefore, only one chassis and multiple different types of carriages 3 are needed to meet the various service needs of the park, reducing procurement and later maintenance costs.

[0039] In the specific implementations provided in the present disclosure, the locking mechanism 4 can be designed in any suitable manner according to actual needs. Figure 1 and Figure 2As shown, the locking mechanism 4 may include a positioning pin 41, which is telescopically mounted on the chassis body 1 in the vertical direction to selectively lock and connect with the carriage 3. During the sliding installation of the carriage 3 and the chassis body 1, the positioning pin 41 may be retracted to avoid interference with the carriage 3. When the sliding installation of the chassis body 1 and the carriage 3 is completed, the positioning pin 41 extends and plugs into the carriage 3 to achieve a locking connection between the carriage 3 and the chassis body 1, and simultaneously achieves the positioning of the carriage 3. The selective locking of the carriage 3 and the chassis body 1 can be achieved by the positioning pin 41 in the vertical telescopic direction. The structure is simple and easy to implement. The specific plug-in structure of the positioning pin 41 and the carriage 3 in use can select any appropriate design according to actual conditions. For example, a positioning hole is provided at the corresponding position of the positioning pin 41 at the bottom of the carriage 3 to achieve selective plug-in. The present disclosure does not impose specific restrictions on this. Among them, the number of positioning pins 41 can be multiple, and multiple positioning pins 41 are arranged around the circumference of the chassis body 1. By setting multiple positioning pins 41, the locking effect between the car body 3 and the chassis body 1 and the positioning effect of the car body 3 are further improved. At the same time, the use of multiple positioning pins 41 can also prevent the car body 3 from sliding during use, making the connection between the car body 3 and the chassis body 1 more stable.

When the carriage 3 needs to be replaced, the multiple rollers 21 in each row of rollers 21 rotate clockwise to achieve the gradual separation of the carriage 3 from the chassis body 1. When the carriage 3 is installed with the chassis body 1, the multiple rollers 21 in each row of rollers 21 rotate counterclockwise, and the rollers 21 abut against the carriage 3 to drive the carriage 3 to slide along the installation groove 11 to complete the installation with the chassis body 1. In specific use, the conveying structure 2 can also be set as a gear rack structure, and the gear can be rotatably arranged on the chassis body 1 around the rotation axis extending in the transverse direction, and the rack extends in the longitudinal direction and is used to abut against the carriage 3, and the rack can be provided with a connecting piece that cooperates with the carriage 3.
