Description
Technical Field
[0001] The utility model relates to the technical field of automobile chassis, in particular to an automobile chassis with an anti-collision buffer structure. Background Art
[0002] An automobile chassis is composed of four parts: a powertrain, a running gear, a steering system, and a braking system. The function of the chassis is to support and install the automobile engine and its various components and assemblies, form the overall shape of the automobile, and receive the power of the engine to make the automobile move and ensure normal driving.
[0003] When an automobile is running, the impact and vibration directly transmitted from the chassis to the ground will be transmitted to the interior of the vehicle, affecting the comfort of the passengers in the automobile. Especially when driving on an unpaved road, once the chassis bottoms out, the force will be directly transmitted to the frame and the body, not only affecting the comfort, but also resulting in high repair costs. Summary of the Utility Model
[0004] The utility model provides an automobile chassis with an anti-collision buffer structure to solve the problems that the impact and vibration directly transmitted from the automobile chassis to the ground will be transmitted to the interior of the vehicle, affecting the comfort of the passengers in the automobile, and the chassis will be damaged, resulting in high repair costs.
[0005] To achieve the above object, the utility model adopts the following technical scheme: an automobile chassis with an anti-collision buffer structure, including a chassis body. A front connecting piece is fixedly connected to one side of the chassis body, and a rear connecting piece is fixedly connected to the other side of the chassis body. An auxiliary buffer device for protecting and buffering the bottom of the chassis is arranged at the bottom of the chassis body. The auxiliary buffer device includes an airbag and a protection plate.
[0006] The effects achieved by the above components are as follows: By setting the airbag, when the airbag is inflated, the airbag will expand, and the protection plate will move downward under the action of the expansion of the airbag. The protection plate can block the bottom of the chassis, which is beneficial to preventing the collision between the chassis of the vehicle and the ground when the vehicle is running, reducing the damage suffered by the chassis body, and the inflated airbag can offset most of the vehicle body vibration caused by the collision, improving the riding comfort and reducing the maintenance cost.
[0007] Preferably, an auxiliary groove is formed at the bottom of the chassis body. One side of the airbag is fixedly connected to the inner wall of the auxiliary groove. A blower is arranged on one side of the inner wall of the auxiliary groove. The output end of the blower is communicated with the inner wall of the airbag. The other side of the airbag is fixedly connected to a protection plate. The shape of the protection plate is adapted to the shape of the chassis. The protection plate is made of ferroalloy. Two magnetic blocks are symmetrically fixedly connected to one side of the inner wall of the airbag. The protection plate is magnetically attracted by the two magnetic blocks.
[0008] The effects achieved by the above components are as follows: By setting the auxiliary groove, in the normal state, both the airbag and the protection plate are on the inner wall of the auxiliary groove, and the two magnetic blocks will attract the protection plate, which can play a role in limiting the airbag and the protection plate. When the fan gradually inflates the airbag, the airbag will gradually expand, causing the protection plate to move away from the magnetic block and creating a certain distance between the protection plate and the chassis body. Therefore, when the chassis body is bumped, the airbag can absorb most of the external force and reduce the vibration received by the chassis body and the vehicle body.
[0009] Preferably, a plurality of limiting rings are fixedly connected to the inner wall of the airbag, and the limiting rings are made of rigid metal materials.
[0010] The effects achieved by the above components are as follows: By setting the limiting rings, the rigid limiting rings are not easily deformed, which can limit the deformation of the airbag and is beneficial to preventing the problem that the airbag expands excessively in the horizontal direction, resulting in the inconvenience of normal driving of the vehicle.
[0011] Preferably, an auxiliary component is arranged inside the airbag. The auxiliary component includes four springs, and the four springs are respectively arranged at the four corners inside the airbag. Both ends of the springs are fixedly connected to both sides of the inner wall of the airbag.
[0012] The effects achieved by the above components are as follows: By setting the springs, when the airbag inflates and expands under the action of the fan, it will drive the springs to deform. At the same time, when the airbag deflates and shrinks under the action of the fan, the deformed springs lose the support of the airbag and will drive the protection plate connected to the airbag to reset under the joint action of the two magnetic blocks, causing the protection plate to enter the auxiliary groove, thereby preventing the protection plate from having a negative impact on the vehicle when the vehicle is driving on a normal road section.
[0013] Preferably, a round rod and a cylinder are arranged inside the spring. The outer surface of the round rod is slidably connected to the inner wall of the cylinder, and one ends of the cylinder and the round rod are respectively fixedly connected to both sides of the inner wall of the airbag.
[0014] The effects achieved by the above components are as follows: By setting the round rod and the cylinder, when the spring deforms and resets, it will drive the round rod to slide synchronously on the inner wall of the cylinder, which can play a role in limiting the spring and prevent the spring from bending during the deformation process.
[0015] Preferably, a detachable device is arranged on one side of the protection plate. The detachable device includes a rubber plate, and the rubber plate is arranged at the bottom of the protection plate.
[0016] The effects achieved by the above components are as follows: By setting a rubber plate at the bottom of the chassis, the rubber plate can shield the protection plate, improve the shock absorption ability of the protection plate and reduce the damage suffered by the protection plate without affecting the strength of the protection plate itself. Moreover, the cost of the rubber plate is much lower than that of the protection plate made of metal material, which can further reduce the cost required for maintenance.
[0017] Preferably, two clamping blocks are symmetrically and fixedly connected to both sides of the protection plate, clamping grooves are symmetrically formed on both sides of the rubber plate, and the outer surface of the clamping block is inserted into the inner wall of the clamping groove.
[0018] The effects achieved by the above components are as follows: By setting the clamping block and the clamping groove and inserting the clamping block into the inner wall of the clamping groove, the positioning between the rubber plate and the protection plate can be realized, which is convenient for the subsequent installation process of the rubber plate.
[0019] Preferably, a pressing plate is arranged on one side of the clamping block, a bolt is inserted into the inner wall of the pressing plate, the outer surface of the bolt is threadedly inserted into the inner wall of the clamping block, and one side of the pressing plate abuts against one side of the rubber plate.
[0020] The effects achieved by the above components are as follows: By setting the pressing plate, inserting the bolt into the inner wall of the pressing plate and rotating the bolt so that the bolt enters the inner wall of the clamping block until one side of the pressing plate abuts against one side of the rubber plate, the rubber plate and the protection plate can be fixed, and at the same time, the rubber plate is detachable, which is convenient for the separate maintenance and replacement of the rubber plate.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0028] Example 1, refer to Figures 1-3 As shown, this example discloses an automobile chassis with an anti-collision buffer structure, including a chassis body 1. A front connecting piece 2 is fixedly connected to one side of the chassis body 1, and a rear connecting piece 3 is fixedly connected to the other side of the chassis body 1. An auxiliary buffer device 4 for protecting and buffering the bottom of the chassis is arranged at the bottom of the chassis body 1. The auxiliary buffer device 4 includes an airbag 41 and a protection plate 42. By setting the airbag 41, when the airbag 41 is inflated, the airbag 41 will expand, and the protection plate 42 will move downward under the action of the expansion of the airbag 41. The protection plate 42 can shield the bottom of the chassis, which is beneficial to preventing the chassis of the vehicle from colliding with the ground when the vehicle is driving, reducing the damage suffered by the chassis body 1, and the inflated airbag 41 can offset most of the vehicle body vibrations caused by collisions, improving the riding comfort and reducing the maintenance cost
[0029] Refer to Figure 2 and Figure 3As shown, an auxiliary groove 43 is formed at the bottom of the chassis body 1. One side of the airbag 41 is fixedly connected to the inner wall of the auxiliary groove 43. A blower 44 is arranged on one side of the airbag 41. The blower 44 is arranged on one side of the inner wall of the auxiliary groove 43. The output end of the blower 44 is communicated with the inner wall of the airbag 41. The other side of the airbag 41 is fixedly connected to a protection plate 42. The shape of the protection plate 42 is adapted to the shape of the chassis body 1. The protection plate 42 is made of ferroalloy. Two magnetic blocks 45 are symmetrically and fixedly connected to one side of the inner wall of the airbag 41. The protection plate 42 is magnetically attracted by the two magnetic blocks 45. By providing the auxiliary groove 43, in the normal state, both the airbag 41 and the protection plate 42 are on the inner wall of the auxiliary groove 43. The two magnetic blocks 45 will attract the protection plate 42, which can play a role in limiting the airbag 41 and the protection plate 42. When the blower 44 gradually inflates the airbag 41, the airbag 41 will gradually expand, causing the protection plate 42 to move away from the magnetic blocks 45 and creating a certain distance between the protection plate 42 and the chassis body 1. Thus, when the chassis body 1 is bumped, the airbag 41 can absorb most of the external force and reduce the vibration received by the chassis body 1 and the vehicle body. A number of limiting rings 46 are fixedly connected to the inner wall of the airbag 41. The limiting rings 46 are made of rigid metal. By providing the limiting rings 46, the rigid limiting rings 46 are not easily deformed, which can limit the deformation of the airbag 41 and help prevent the problem that the airbag 41 expands excessively in the horizontal direction, making it difficult for the vehicle to drive normally.
[0030] Referring to Figure 2 and Figure 3 As shown, an auxiliary component 47 is arranged inside the airbag 41. The auxiliary component 47 includes four springs 471. The four springs 471 are respectively arranged at the four corners inside the airbag 41. The two ends of the springs 471 are respectively fixedly connected to both sides of the inner wall of the airbag 41. By providing the springs 471, when the airbag 41 inflates and expands under the action of the blower 44, it will drive the springs 471 to deform. At the same time, when the airbag 41 deflates and shrinks under the action of the blower 44, the deformed springs 471 lose the support of the airbag 41 and will drive the protection plate 42 connected to the airbag 41 to reset under the combined action of the two magnetic blocks 45, causing the protection plate 42 to enter the auxiliary groove 43, thereby preventing the protection plate 42 from having a negative impact on the vehicle when the vehicle is driving on a normal road section. A round rod 472 and a cylinder 473 are arranged inside the spring 471. The outer surface of the round rod 472 is slidably connected to the inner wall of the cylinder 473. One end of the cylinder 473 and the round rod 472 are respectively fixedly connected to both sides of the inner wall of the airbag 41. By providing the round rod 472 and the cylinder 473, when the spring 471 deforms and resets, it will drive the round rod 472 to slide synchronously on the inner wall of the cylinder 473, which can play a role in limiting the spring 471 and prevent the spring 471 from bending during the deformation process.
[0031] Referring to Figure 2and Figure 4 As shown, a detachable device 5 is provided on one side of the protection plate 42. The detachable device 5 includes a rubber plate 51. The rubber plate 51 is arranged at the bottom of the protection plate 42. By arranging the rubber plate 51 at the bottom of the chassis, the rubber plate 51 can shield the protection plate 42, improve the shock absorption capacity of the protection plate 42 and reduce the damage suffered by the protection plate 42 without affecting the strength of the protection plate 42 itself. Moreover, the cost of the rubber plate 51 is much cheaper than that of the protection plate 42 made of metal material, which can further reduce the cost required for maintenance.
[0032] Referring to Figure 2 and Figure 4 As shown, two clamping blocks 52 are symmetrically and fixedly connected to both sides of the protection plate 42. Slots 53 are symmetrically formed on both sides of the rubber plate 51. The outer surface of the clamping block 52 is inserted into the inner wall of the slot 53. By providing the clamping block 52 and the slot 53 and inserting the clamping block 52 into the inner wall of the slot 53, the positioning between the rubber plate 51 and the protection plate 42 can be achieved, thus facilitating the subsequent installation process of the rubber plate 51. A pressing plate 54 is arranged on one side of the clamping block 52. A bolt 55 is inserted into the inner wall of the pressing plate 54. The outer surface of the bolt 55 is threadedly inserted into the inner wall of the clamping block 52. One side of the pressing plate 54 abuts against one side of the rubber plate 51. By providing the pressing plate 54, inserting the bolt 55 into the inner wall of the pressing plate 54 and rotating the bolt 55 so that the bolt 55 enters the inner wall of the clamping block 52 until one side of the pressing plate 54 abuts against one side of the rubber plate 51, the fixing between the rubber plate 51 and the protection plate 42 can be achieved, and at the same time, the rubber plate 51 can be detached, thus facilitating the separate maintenance and replacement of the rubber plate 51.
[0033] Working principle: Under normal conditions, both the airbag 41 and the protection plate 42 are on the inner wall of the auxiliary groove 43. The two magnetic blocks 45 will attract the protection plate 42, which can limit the airbag 41 and the protection plate 42. When the blower 44 gradually inflates the airbag 41, the airbag 41 will gradually expand, causing the protection plate 42 to move away from the magnetic block 45 and creating a certain distance between the protection plate 42 and the chassis body 1. Thus, when the chassis body 1 is bumped, the airbag 41 can absorb most of the external force, reducing the vibration received by the chassis body 1 and the vehicle body. At the same time, when the airbag 41 deflates and shrinks under the action of the blower 44, the deformed spring 471 loses the support of the airbag 41 and will drive the protection plate 42 connected to the airbag 41 to reset under the combined action of the two magnetic blocks 45, causing the protection plate 42 to enter the auxiliary groove 43, thereby preventing the protection plate 42 from having a negative impact on the vehicle when the vehicle is driving on normal roads; when installing the rubber plate 51, insert the block 52 into the inner wall of the card slot 53 and insert the bolt 55 into the inner wall of the pressing plate 54. Rotate the bolt 55 so that the bolt 55 enters the inner wall of the block 52 until one side of the pressing plate 54 abuts against one side of the rubber plate 51, then the rubber plate 51 and the protection plate 42 can be fixed. The rubber plate 51 can shield the protection plate 42, improving the shock absorption capacity of the protection plate 42 and reducing the damage received by the protection plate 42 without affecting the strength of the protection plate 42 itself. Moreover, the cost of the rubber plate 51 is much cheaper than that of the metal protection plate 42, which can further reduce the maintenance cost.
