Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicles, in particular to a chassis assembly for a vehicle and a vehicle. BACKGROUND

[0002] Vehicle rollover is a common traffic accident, which can cause serious damage to vehicles and people. Vehicle rollover is due to the centrifugal force generated by the vehicle when changing direction at high speed. The chassis of the vehicle will tilt under the action of the centrifugal force, and the vehicle will roll over when the centrifugal force is large enough.

[0003] The higher the center of gravity of the vehicle, the greater the lateral roll moment generated by the centrifugal force, so reducing the center of gravity of the vehicle can make the vehicle less likely to roll over when turning at high speed. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, one object of the present application is to propose a chassis assembly. According to the chassis assembly of the present application, by providing a first lifting member and a second lifting member, the first lifting member or the second lifting member can be moved towards the lower side of the chassis body to reduce the risk of vehicle rollover, and by providing a driving member, the driving member can correspondingly drive the first lifting member or the second lifting member to move towards the lower side of the chassis body when the chassis body tilts.

[0036] Embodiments of the present application are described in detail below with reference to the attached drawings, wherein the same or like reference numerals in the drawings and the description below indicate the same or like elements or components having the same or similar function. The embodiments described below are exemplary only, and are not to be construed as limiting the present application.

[0037] In the related art, the higher the center of gravity of the vehicle, the greater the lateral roll moment generated by the centrifugal force, and thus lowering the center of gravity of the vehicle can make the vehicle less likely to roll over when turning at high speed.

[0038] Reference will be made to the drawings Figures 1-9 A chassis assembly according to an embodiment of the present application is described.

[0039] As Figures 1-3 shown, the chassis assembly 1 according to the present application is used for a vehicle, the chassis assembly 1 comprising a chassis body 11, a first lifting member 12, a second lifting member 13 and a driving member 14, the first lifting member 12 being movably arranged on one side of the chassis body 11 in the width direction of the vehicle; the second lifting member 13 being movably arranged on the other side of the chassis body 11 in the width direction of the vehicle; the driving member 14 being movably arranged on the chassis body 11 and connected with the first lifting member 12 and the second lifting member 13 respectively; wherein the chassis body 11 is inclined towards one side in the width direction, the driving member 14 moves towards the first lifting member 12 to drive the second lifting member 13 to move downwards relative to the chassis body 11; or, the chassis body 11 is inclined towards the other side in the width direction, the driving member 14 moves towards the second lifting member 13 to drive the first lifting member 12 to move downwards relative to the chassis body 11.

[0040] The chassis assembly 1 according to the present application, when the chassis body 11 is inclined towards one side in the width direction, the second lifting member 13 moves downwards relative to the chassis body 11; when the chassis body 11 is inclined towards the other side in the width direction, the first lifting member 12 moves downwards relative to the chassis body 11. By arranging the first lifting member 12 and the second lifting member 13, when the chassis body 11 is inclined towards one side or the other side in the width direction, the first lifting member 12 or the second lifting member 13 on the side opposite to the direction in which the chassis body 11 is inclined can move downwards relative to the chassis body 11, which lowers the center of gravity of the chassis assembly 1 and makes the position of the center of gravity relative to the ground deviate towards the moving direction of the first lifting member 12 or the second lifting member 13, so that the gravity of the chassis assembly 1 can counteract the centrifugal force generated by the turning of the vehicle, thereby reducing the risk of the vehicle rolling over.

[0041] The chassis assembly 1 according to the present application, when the chassis body 11 is inclined towards one side in the width direction, the driving member 14 can move towards one side in the width direction to drive the second lifting member 13 to move downwards relative to the chassis body 11; when the chassis body 11 is inclined towards the other side in the width direction, the driving member 14 can move towards the other side in the width direction to drive the first lifting member 12 to move downwards relative to the chassis body 11. By arranging the driving member 14, the first lifting member 12 or the second lifting member 13 can move downwards when the chassis body 11 is inclined.

[0042] Therefore, the chassis assembly 1 of the present application, by setting the first lifting piece 12 and the second lifting piece 13, the first lifting piece 12 or the second lifting piece 13 can be moved towards the bottom of the chassis body 11 to reduce the risk of vehicle rollover, and by setting the driving piece 14, the driving piece 14 can correspondingly drive the first lifting piece 12 or the second lifting piece 13 to move towards the bottom of the chassis body 11 when the chassis body 11 is inclined.

[0043] According to some embodiments of the present application, as Figures 5-8As shown, the first lifting member 12 and the second lifting member 13 are respectively provided with a first sliding part 121 and a second sliding part, and the driving member 14 is provided with a third sliding part 141 and a fourth sliding part which are matched with the first sliding part 121 and the second sliding part respectively; wherein one of the first sliding part 121 and the third sliding part 141 is configured as a first sliding groove 121a, and the other of the first sliding part 121 and the third sliding part 141 is configured as a first sliding block 141b; one of the second sliding part and the fourth sliding part is configured as a second sliding groove, and the other of the second sliding part and the fourth sliding part is configured as a second sliding block; the first sliding groove 121a and the second sliding groove are inclined upwards from the driving member 14. The first sliding part 121 and the third sliding part 141 can slide relative to each other to make the driving member 14 slide relative to the first lifting member 12. The first sliding block 141b can slide in the first sliding groove 121a to make the driving member 14 slide relative to the first lifting member 12. By configuring the first sliding groove 121a to be inclined upwards from the driving member 14, the sliding of the first sliding block 141b in the first sliding groove 121a can generate a pressure or a support force on the first lifting member 12 to make the first lifting member 12 move towards the bottom chassis body 11 or move from the bottom chassis body 11 towards the bottom chassis body 11. Specifically, when the bottom chassis body 11 is inclined towards the other side, the driving member 14 moves towards the other side of the bottom chassis body 11; the first sliding block 141b can be arranged on the driving member 14, and the first sliding block 141b is inclined upwards in the first sliding groove 121a to make the first lifting member 12 move towards the bottom chassis body 11; the first sliding block 141b can also be arranged on the first lifting member 12, and the first sliding block 141b is inclined downwards in the first sliding groove 121a to make the first lifting member 12 move towards the bottom chassis body 11. When the bottom chassis body 11 recovers from the inclination towards the other side to the balanced state, the driving member 14 moves towards one side of the bottom chassis body 11 until it returns to the starting position; the first sliding block 141b can be arranged on the driving member 14, and the first sliding block 141b is inclined downwards in the first sliding groove 121a to make the first lifting member 12 move from the bottom chassis body 11 towards the bottom chassis body 11, and the first lifting member 12 is recovered to keep the bottom chassis body 11 in the balanced state; the first sliding block 141b can also be arranged on the first lifting member 12, and the first sliding block 141b is inclined upwards in the first sliding groove 121a to make the first lifting member 12 move from the bottom chassis body 11 towards the bottom chassis body 11, and the first lifting member 12 is recovered to keep the bottom chassis body 11 in the balanced state. Therefore, by arranging the first sliding block 141b and the first sliding groove 121a, the driving member 14 can drive the first lifting member 12 to move towards the bottom chassis body 11 or move from the bottom chassis body 11 towards the bottom chassis body 11. The second sliding part and the fourth sliding part are the same, and are not described here.

[0044] According to some embodiments of the present application, as shown in Figures 5-8 The third sliding part 141 is formed with a first sliding hole 141a extending in the height direction, the first sliding hole 141a is formed with a first sliding block 141b, the first sliding part 121 is movably accommodated in the first sliding hole 141a and the first sliding part 121 is formed with a first sliding groove 121a matched with the first sliding block 141b; the fourth sliding part is formed with a second sliding hole extending in the height direction, the second sliding hole is formed with a second sliding block, the second sliding part is movably accommodated in the second sliding hole and the second sliding part is formed with a second sliding groove matched with the first sliding block 141b. The first sliding part 121 can slide in the first sliding hole 141a, so the first sliding hole 141a can limit the sliding path of the first sliding part 121, keep the first sliding part 121 sliding in the first sliding hole 141a and improve the reliability. The first sliding hole 141a extends in the height direction, so the first sliding part 121 can move in the height direction, thereby enabling the first lifting part 12 to move towards the bottom of the chassis body 11 or move from the bottom of the chassis body 11 towards the chassis body 11. By arranging the first sliding block 141b in the first sliding hole 141a and arranging the first sliding groove 121a on the first sliding part 121, the first sliding part 121 can be accommodated in the first sliding hole 141a while the first sliding block 141b matches the first sliding groove 121a, so that the first sliding part 121 can move in the first sliding hole 141a, saving assembly procedures and facilitating processing. The second sliding part and the fourth sliding part are the same, and will not be described here.

[0045] According to some embodiments of the present application, as shown in Figures 6-8 The first sliding groove 121a and the first sliding block 141b are configured as a plurality of one-to-one corresponding arrangements in the width direction of the chassis body 11; the second sliding groove and the second sliding block are configured as a plurality of one-to-one corresponding arrangements in the width direction of the chassis body 11. By configuring the first sliding groove 121a and the first sliding block 141b as a plurality of one-to-one corresponding arrangements, the plurality of first sliding grooves 121a and the plurality of first sliding blocks 141b are arranged one-to-one to realize synchronous movement of the plurality of first sliding blocks 141b, so that when the first sliding block 141b and the first sliding groove 121a are matched and slid, the pressure or support force on the first lifting part 12 increases, and the first lifting part 12 can move in time and quickly to resist the centrifugal force generated by the vehicle turning when the chassis body 11 is tilted. The plurality of first sliding grooves 121a and the plurality of second sliding grooves are arranged in the width direction of the chassis body 11, so that the pressure or support force on the first lifting part 12 in the width direction is uniform, thereby enabling the first lifting part 12 to move smoothly and reliably towards the bottom of the chassis body 11 or move from the bottom of the chassis body 11 towards the chassis body 11. The second sliding groove and the second sliding block are the same, and will not be described here.

[0046] According to some embodiments of the present application, as shown in Figure 6 The first sliding part 121 is configured in multiple and arranged at intervals in the length direction of the chassis body 11. The second sliding part is configured in multiple and arranged at intervals in the length direction of the chassis body 11. By configuring the first sliding part 121 in multiple, the multiple first sliding parts 121 are respectively matched with the multiple third sliding parts 141 of the driving part 14, so that the first sliding part 121 and the third sliding part 141 are matched and slid to increase the pressure or support force on the first lifting part 12, so that the first lifting part 12 can move in time and quickly to resist the centrifugal force generated by the vehicle turning when the chassis body 11 is tilted. The multiple first sliding parts 121 are arranged at intervals in the length direction of the chassis body 11, so that the pressure or support force on the first lifting part 12 in the length direction is uniform, so that the first lifting part 12 can move smoothly and reliably towards the lower part of the chassis body 11 or move from the lower part of the chassis body 11 to the chassis body 11. The second sliding part is the same, which will not be described here.

[0047] According to some embodiments of the present application, as shown in Figure 3 and Figure 5As shown, the chassis body 11 is formed with a first limiting groove 111 and a second limiting groove 112 on both sides in the width direction, the driving member 14 is arranged between the first limiting groove 111 and the second limiting groove 112, and the first lifting member 12 and the second lifting member 13 are arranged in the first limiting groove 111 and the second limiting groove 112 respectively; the chassis assembly 1 further comprises a first reset member 15 and a second reset member, the first reset member 15 is arranged between the first lifting member 12 and the inner wall of the first limiting groove 111; and the second reset member is arranged between the second lifting member 13 and the inner wall of the second limiting groove 112. By arranging the first limiting groove 111 and the second limiting groove 112, the first limiting groove 111 can limit the lateral movement of the first lifting member 12, and the second limiting groove 112 can limit the lateral movement of the second lifting member 13, so that the first lifting member 12 and the second lifting member 13 can only move towards the lower side of the chassis body 11 or move from the lower side of the chassis body 11 towards the chassis body 11, thereby improving the reliability. The first reset member 15 is used to reset the first lifting member 12 after the first lifting member 12 moves towards the lower side of the chassis body 11, and the second reset member is used to reset the second lifting member 13 after the second lifting member 13 moves towards the lower side of the chassis body 11, so that when the chassis body 11 recovers from the inclined state to the balanced state, the first sliding part 121 slides relative to the third sliding part 141 to reset the first lifting member 12, or the second sliding part slides relative to the fourth sliding part to reset the second lifting member 13. By arranging the first reset member 15 and the second reset member, the first reset member 15 can generate a force to make the first sliding part 121 slide relative to the third sliding part 141, and the second reset member can generate a force to make the second sliding part slide relative to the fourth sliding part, so that the first lifting member 12 and the second lifting member 13 can be reset when the chassis body 11 recovers to the balanced state. The first reset member 15 is arranged between the first lifting member 12 and the inner wall of the first limiting groove 111, the first reset member 15 can be arranged between the first lifting member 12 and the top wall of the first limiting groove 111, and the first reset member 15 can generate a pulling force on the first lifting member 12 to reset the first lifting member 12; the first reset member 15 can also be arranged between the first lifting member 12 and the side wall of the first limiting groove 111, and push or pull the first sliding part 121 to make the first sliding part 121 and the third sliding part 141 slide relative to each other when the first lifting member 12 is reset. The second reset member is the same, which is not described here. Specifically, the first reset member 15 and the second reset member can be springs.

[0048] According to some embodiments of the present application, as Figure 9As shown, the driving member 14 includes a mass block 142, a first linkage rod 143 and a second linkage rod 144. The mass block 142 is movably arranged on the chassis body 11 and moves with the chassis body 11 to tilt. The first linkage rod 143 and the second linkage rod 144 are arranged on two sides of the mass block 142 in the width direction and are linked with the first sliding part 121 and the second sliding part respectively. By arranging the mass block 142, the mass block 142 can move with the chassis body 11 to tilt to move to one side of the chassis body 11. The driving member 14 can move under the action of its own gravity, so that the driving member 14 can spontaneously move to one side or the other side of the chassis body 11 in the width direction according to the different tilting directions of the chassis body 11, and the automation level is high, and the first lifting member 12 and the second lifting member 13 can respond in time when the chassis body 11 tilts. By arranging the first linkage rod 143 and the second linkage rod 144, the first linkage rod 143 and the second linkage rod 144 move with the movement of the mass block 142. The first linkage rod 143 is linked with the first sliding part 121, and the second linkage rod 144 is linked with the second sliding part. Specifically, the first linkage rod 143 is slidably connected with the first sliding part 121, and the second linkage rod is slidably connected with the second sliding part. When the first linkage rod 143 moves in the direction of the first sliding part 121, that is, the chassis body 11 tilts to one side in the width direction, the first linkage rod 143 slides relative to the first sliding part 121, and the first sliding part 121 does not move. The second linkage rod 144 pulls the second sliding part to move synchronously to make the second sliding part slide relative to the fourth sliding part, and the second lifting member 13 moves toward the lower side of the chassis body 11. The same is true when the chassis body 11 tilts to the other side in the width direction. By arranging the first linkage rod 143 and the second linkage rod 144, when the chassis body 11 tilts, the mass block 142 can transmit power to the side opposite to the tilting direction through the first linkage rod 143 and the second linkage rod 144, so as to realize the movement of the first lifting member 12 or the second lifting member 13 toward the lower side of the chassis body 11.

[0049] According to some embodiments of the present application, as Figure 4As shown, a limiting shell 113 is formed on the chassis body 11, and a containing space suitable for accommodating the mass block 142 is formed in the limiting shell 113. The limiting shell 113 is provided with a first guide portion 113a and a second guide portion 113b on both sides in the width direction, which are matched with the first linkage rod 143 and the second linkage rod 144 respectively. The first guide portion 113a matched with the first linkage rod 143 can make the first linkage rod 143 move in the width direction of the chassis body 11, and restrict the movement of the first linkage rod 143 in other directions. Specifically, the first guide portion 113a can be a through hole extending in the width direction of the chassis body 11, and the first linkage rod 143 passes through the through hole, so that the first linkage rod 143 can only move along the extension direction of the through hole, so as to realize that the first linkage rod 143 can only move in the width direction of the chassis body 11. The second guide portion 113b is matched with the second linkage rod 144 in the same way, which will not be described here.

[0050] In some embodiments of the present application, a third guide portion is formed in the limiting shell 113 and matched with the mass block 142. The third guide portion matched with the mass block 142 can make the mass block 142 move in the width direction of the chassis body 11, and restrict the movement of the mass block 142 in other directions. Specifically, the third guide portion can be connected to the inner wall of the limiting shell 113 at both ends and extend in the width direction of the chassis body 11, and the mass block 142 is formed with a guide hole penetrating in the width direction of the chassis body 11, and the guide rod 113c passes through the guide hole to make the mass block 142 only move in the width direction of the chassis body 11.

[0051] According to some embodiments of the present application, as Figure 6 As shown, the bottom surfaces of the first lifting piece 12 and the second lifting piece 13 are respectively configured as arc shapes protruding towards the bottom surface of the chassis. By configuring the bottom surfaces of the first lifting piece 12 and the second lifting piece 13 as arc shapes protruding towards the bottom surface of the chassis, the distance through which the air flows through the bottom surfaces of the first lifting piece 12 or the second lifting piece 13 can be prolonged, the air flow on the bottom surfaces is accelerated to reduce the pressure generated by the air on the bottom surfaces of the first lifting piece 12 and the second lifting piece 13, and the counteraction of the gravity of the chassis assembly 1 to the centrifugal force generated by the vehicle turning is further promoted, and the risk of vehicle rollover is further reduced.

[0053] The vehicle according to the present application includes the chassis assembly 1 in any one of the above embodiments. Since the vehicle according to the present application includes the chassis assembly 1 in any one of the above embodiments, the first lifting piece 12 or the second lifting piece 13 can move downward when the chassis body 11 inclines to enhance the stability of the chassis assembly 1, the risk of vehicle rollover is low, and the safety is high.
