The vehicle chassis of the present invention is described below with reference to fig. 1 to 3.

As shown in fig. 1, an embodiment of the present invention provides a vehicle chassis, which includes a chassis base 10, a telescopic assembly 20, a shock absorbing device 30, a working platform 40, and wheels 50. Wherein, four wheels 50 are in a group two by two, and two wheels 50 in the same group are connected through a wheel frame 51. The two telescopic assemblies 20 are arranged corresponding to the two wheel frames 51 one by one, one end of each telescopic assembly 20 is rotatably connected with the corresponding wheel frame 51, and the other end of each telescopic assembly 20 is rotatably connected with the chassis base 10. Each wheel 50 is connected to the chassis base 10 by a shock absorbing device 30. The working platform 40 includes a fixing plate 41 and a display plate 42, the fixing plate 41 is fixed to the chassis base 10, and the display plate 42 is rotatably connected to the fixing plate 41.

As shown in fig. 1 to 3, four wheels 50 are connected to the chassis base 10, wherein two wheels 50 form a group, and two wheels 50 in the same group are connected through a wheel frame 51. The two wheel frames 51 are connected to the chassis base 10 via a respective telescopic assembly 20. When the telescopic assembly 20 is extended and retracted, the two wheel frames 51 are driven to move close to or away from each other, so as to adjust the height of the chassis base 10. Optionally, the telescopic assembly 20 comprises a hydraulic telescopic rod, and when the hydraulic telescopic rod is at the longest length, as shown in fig. 1 and 2, the chassis base 10 is in a low chassis state; when the hydraulic telescopic rod is at the shortest length, as shown in fig. 3, the chassis base 10 is in a high chassis state. The switching between the high chassis state and the low chassis state is achieved by the telescoping of the telescoping assembly 20.

Each wheel 50 is connected to the chassis base 10 through a shock absorbing device 30, and both ends of the shock absorbing device 30 are rotated with respect to the connecting members when the height of the chassis base 10 is adjusted, so as to accommodate adjustment of the chassis height.

As shown in fig. 1, the working platform 40 includes a fixing plate 41 and a display plate 42, and the fixing plate 41 is fixedly mounted on the chassis base 10. For example, the fixing plate 41 is integrally formed with the chassis base 10 or bolted thereto. The display board 42 is rotatably mounted on the fixing board 41, and when the size of the working platform 40 needs to be increased, as shown in fig. 2, the display board 42 is unfolded relative to the fixing board 41, so as to support more objects. When not needed, the display board 42 is folded with respect to the fixing board 41, as shown in fig. 1 and 3, so that the display board 42 is in a stored state and the working platform 40 is in a small-sized state.

In the vehicle chassis provided by the embodiment of the invention, the fixed plate 41 and the display plate 42 can be rotatably connected and can be in a folded or unfolded state, so that the size of the working platform 40 is adjusted; the distance between the two wheel frames 51 is adjusted by means of the extension and contraction of the telescopic assembly 20, so that the ground clearance of the chassis base 10 is adjusted to adapt to different road conditions. Therefore, the vehicle chassis has a plurality of forms and a wide application range.

Wherein, both ends of the wheel frame 51 are respectively rotatably connected with a rotating frame 52, and the wheel 50 is connected with the rotating frame 52. The wheel frame 51 is provided with a rotary driving member 53 for driving the rotary frame 52 to rotate relative to the wheel frame 51, and the rotary frame 52 is provided with a traveling driving member 54 for driving the wheel 50 to advance or retreat.

Alternatively, the rotary drive 53 and the travel drive 54 are both rotary motors. Specifically, a walking driving member 54 is fixedly mounted on the rotating frame 52, and the wheel 50 is in transmission connection with the walking driving member 54 through a coupling. The wheels 50 are rotated by the travel drive 54 to effect forward or reverse travel. The rotary driving member 53 drives the rotary frame 52 to rotate and simultaneously drives the wheel 50 to synchronously rotate, so that the wheel 50 is turned.

When the height of the chassis base 10 from the ground is adjusted, the rotary driving member 53 drives the rotary frame 52 to rotate relative to the wheel frame 51, so as to adjust the direction of the wheel 50, and the walking driving member 54 drives the wheel 50 to move forward, so that the wheel 50 cooperates with the telescopic assembly 20 to complete the height adjustment of the chassis base 10. Specifically, during the process of switching the chassis base 10 from the high chassis state to the low chassis state, the rotary driving member 53 drives the two wheels 50 at the front end of the chassis base 10 to rotate inward and move toward the middle of the chassis base 10 under the action of the walking driving member 54, and the telescopic assembly 20 is shortened, thereby cooperatively completing the state switching. The process of switching the chassis base 10 from the low chassis state to the high chassis state is similar to the above, and will not be described again.

In use, the wheel 50 can be driven to reverse in situ by rotating the drive member 53 to adjust the direction of travel of the vehicle in a confined space. For example, as shown in fig. 1, the wheel 50 moves forward or backward along the length direction of the chassis base 10, and the rotary driving member 53 drives the rotary frame 52 to rotate 90 ° relative to the wheel frame 51, so that the wheel 50 moves forward or backward along the width direction of the chassis base 10, as shown in fig. 2.

According to the vehicle chassis provided by the embodiment of the invention, the height of the chassis base 10 is adjusted by matching the rotary driving piece 53 and the walking driving piece 54 which are arranged on the wheel 50 with the telescopic assembly 20, so that the hard friction between the wheel 50 and the ground is reduced, and meanwhile, the wheel 50 can be driven to change direction in situ through the rotary driving piece 53, so that the reversing requirement of a narrow space is met.

On the basis of the above embodiment, as shown in fig. 1 and fig. 2, the wheel frame 51 is provided with a connector 55 at the end, the rotating frame 52 is rotatably connected with the connector 55, and the connector 55 is rotatably connected with the damping device 30.

As shown in fig. 1, the connection head 55 is cylindrical, and has two first connection lugs on its outer surface, one of the first connection lugs is used for connecting the damping device 30, and the other first connection lug is used for connecting the wheel frame 51. The end of the connecting head 55 is provided with a second connecting lug, and the second connecting lug is rotatably connected with the rotating frame 52. The rotary driving member 53 is fixed on the second connecting lug and is in driving connection with the rotary frame 52. The rotating frame 52 rotates relative to the connecting head 55 under the driving of the rotary driving member 53.

In one embodiment of the present invention, as shown in fig. 1, one end of the shock absorbing device 30 is rotatably connected to the chassis base 10 through a first locking assembly 31, and the other end is rotatably connected to the wheel frame 51 through a second locking assembly 32.

As shown in fig. 1, the shock absorbing device 30 is disposed between the chassis base 10 and the wheel frame 51, and one shock absorbing device 30 is disposed for each wheel 50. During the state switching process of the chassis base 10, the first locking assembly 31 and the second locking assembly 32 are in the unlocked state, and the two ends of the shock absorbing device 30 can rotate relative to the wheel frame 51 and the chassis base 10, so as to cooperate with the telescopic assembly 20 to realize the height adjustment of the chassis base 10. After the state of the chassis base 10 is switched to the state of locking the chassis base 10, the first locking assembly 31 and the second locking assembly 32 are in a locking state, so that the two ends of the shock absorbing device 30 are respectively in a relatively fixed connection state with the chassis base 10 and the wheel frame 51.

The vehicle chassis provided by the embodiment of the invention ensures that the state of the chassis base 10 after adjustment can be locked by controlling the connection relation between the end part of the damping device 30 and the wheel frame 51 and the chassis base 10 through the first locking assembly 31 and the second locking assembly 32.

The first locking assembly 31 and the second locking assembly 32 are identical in structure. As shown in fig. 1 and 4, the first locking assembly 31 includes a locking driving member 311, a first bracket 312, a second bracket 313 and a piston 314.

The first bracket 312 is fixed on the chassis base 10, the second bracket 313 is fixed on the first bracket 312, and the piston 314 is installed between the first bracket 312 and the second bracket 313. The second bracket 313 is provided with a first fixing plate 315 and a second fixing plate 316, the first fixing plate 315 and the second fixing plate 316 are clamped on the chassis base 10 and the rotation shaft of the damping device 30, and the piston 314 abuts against the first fixing plate 315. Under the driving of the locking driving member 311, the piston 314 pushes the first fixing piece 315 to move towards the second fixing piece 316, so as to clamp on the rotating shafts of the chassis base 10 and the damping device 30, and the chassis base 10 and the damping device 30 are kept relatively fixed by virtue of the friction force provided by clamping, thereby realizing locking. When the rotation is required, the piston 314 moves reversely, so that the first fixing plate 315 and the second fixing plate 316 are in an unlocked state, and the rotating shafts of the chassis base 10 and the shock absorbing device 30 can rotate between the first fixing plate 315 and the second fixing plate 316.

Alternatively, the locking driving member 311 is a hydraulic device, which pushes the piston 314 to move through the hydraulic joint 317, thereby pushing the first fixing plate 315 and the second fixing plate 316 on the second bracket 313 to approach each other. With the release of the hydraulic pressure, the first fixing plate 315 and the second fixing plate 316 move away from each other, and unlocking is achieved. It should be noted that the first locking assembly 31 and the second locking assembly 32 may be driven by the same locking driving member 311, or may be provided with a locking driving member separately, which is not limited in this embodiment of the present invention.

In the above embodiment, the opposite ends of the fixing plate 41 are provided with extension shafts, and the ends of the extension shafts are fixedly connected to the connecting plate 43. The shock absorbing devices 30 located at the same side ends of the two wheel frames 51 are connected to the opposite ends of the connecting plate 43 in a one-to-one correspondence.

The extension shaft extends in the longitudinal direction of the wheel frame 51. As shown in fig. 1 to 3, the connecting plate 43 is a diamond-shaped plate, and two opposite corners of the connecting plate 43 are connected to the shock absorbing devices 30 on the same side ends of the two wheel frames 51 in a one-to-one correspondence. Thereby, the indirect connection of the damper device 30 and the chassis base 10 is achieved. In an alternative embodiment, the connecting plate 43 is secured in place over the end of the extension shaft. In yet another alternative embodiment, the connecting plate 43 is fastened to the end of the extension shaft by bolts.

According to the vehicle chassis provided by the embodiment of the invention, the damping device 30 positioned at the same side end of the wheel frame 51 is connected with the extension shaft on the fixing plate 41 through the connecting plate 43, so that the size of the fixing plate 41 can be conveniently distributed as required, and the indirect connection between the damping device 30 and the chassis base 10 can be realized.

Optionally, as shown in fig. 1 and 2, the vehicle chassis further includes a connecting shaft 33, one end of the connecting shaft 33 is connected to the connecting plate 43 through the first locking assembly 31, and the other end is fixedly connected to the damping device 30.

During the switching state of the chassis base 10, the connecting shaft 33 and the shock absorbing device 30 are relatively fixed, and the first locking assembly 31 is used for realizing the locking and unlocking of the rotatable connection between the connecting shaft 33 and the connecting plate 43. After the state of the chassis base 10 is switched to the right position, the first locking assembly 31 and the second locking assembly 32 are both in the locking state, so that the whole chassis base 10 is stabilized in the switched state.

In the vehicle chassis provided by the embodiment of the invention, the connecting plate 43 is connected with the damping device 30 through the connecting shaft 33, and the damping device 30 is convenient to mount through the connecting shaft 33.

In an embodiment of the present invention, the display plates 42 include two display plates 42, and the two display plates 42 are rotatably mounted on opposite sides of the fixing plate 41.

As shown in fig. 2, one display board 42 is mounted on each of the opposite sides of the fixing board 41 in the width direction. Wherein, the display board 42 is rotatably connected with the fixing board 41 through a rotating shaft. The two display boards 42 are identical in size and are each half of the fixing board 41. When the two display plates 42 are in the folded state, the two display plates 42 are arranged on the top of the fixing plate 41 in a pair and pressed together. When the two display boards 42 are in the unfolded state, the two display boards 42 extend outwards along two opposite sides of the fixing board 41, so that the whole workbench is kept symmetrical relative to the middle of the chassis base 10.

In an alternative embodiment, as shown in fig. 1, the fixing plate 41 is provided with a driving device 44, and the driving device 44 is used for driving the display plate 42 to rotate relative to the fixing plate 41. Optionally, the rotating shaft is fixedly connected to the display board 42 and rotatably connected to the fixing plate 41, and a driving end of the driving device 44 is connected to the rotating shaft to drive the rotating shaft to rotate, so as to turn the display board 42. Specifically, the drive device 44 is a rotary motor or other rotary drive mechanism. It will be appreciated that two of the drive devices 44 are provided for each of the two panels 42.

As shown in fig. 1 to 3, the camera 63 is fixedly disposed at the front end of the chassis base 10 and is used for taking road condition pictures in the traveling direction of the vehicle. The control box 62 is arranged on the chassis base 10, and the camera 63 and the height monitor 61 are both in communication connection with the control box 62. When the chassis base 10 is in the low chassis posture, if the height of the chassis base 10 needs to be increased according to the road condition picture, the telescopic assembly 20 is controlled to be contracted until the ground clearance detected by the height monitor 61 reaches the target height. Of course, the height of the chassis base 10 can also be determined by the telescopic stroke of the telescopic assembly 20.
