Generally, the anti-collision beam of the side door is deformed by the impact and is repaired by sheet metal or a new anti-collision beam is directly used. The anti-collision beam after the secondary repair will have certain safety hazards when used, and the new anti-collision beam needs to be ordered according to different models and wait for a long time before it can be installed. It cannot be repaired and installed in a short time. Therefore, an anti-collision structure for a vehicle side door is proposed to solve the above problem. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an anti-collision structure for a vehicle side door, which has the advantages of easy installation and a wide range of applications. It solves the problem that the anti-collision beam of the side door is deformed by impact and must be repaired by sheet metal or a new anti-collision beam is directly used. The anti-collision beam after the secondary repair will have certain safety hazards when used, and the new anti-collision beam needs to be ordered according to different vehicle models and waits for a long time before it can be installed, and it cannot be repaired and installed in a short time.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A collision prevention structure for a vehicle side door comprises a side door body, two mounting holes are provided on the left and right sides of the front face of the side door body, two collision prevention bars are arranged on the front face of the side door body, a connecting threaded rod is threadedly connected between the two collision prevention bars, a rotating positioning block is sleeved on the connecting threaded rod and fixedly connected to the two collision prevention bars, the rotating positioning block is located between the two collision prevention bars, uniformly distributed reinforcement cavities are provided inside the two collision prevention bars, positioning blocks are fixedly connected on the left and right sides of the rotating positioning block, uniformly distributed positioning support rods are fixedly connected on the sides of the two positioning blocks away from the rotating positioning blocks, one end of the positioning support rod away from the positioning block extends to the inside of the reinforcement cavity and is slidably connected to the inner wall of the reinforcement cavity, a protective absorption sleeve is sleeved between the two collision prevention bars, and the two collision prevention bars pass through the two collision prevention bars. The rotation positioning block is fixedly connected by four mounting holes respectively through bolts, the front view shape of the rotation positioning block is a cross, the shape of the two positioning blocks is C-shaped, the opposite sides of the two positioning blocks are engaged with the rotation positioning block, four fixing pins are inserted on the two positioning blocks, the bottom ends of the four fixing pins pass through the rotation positioning block and the positioning block in turn and extend to the inside of the rotation positioning block, the two positioning blocks are fixedly connected to the rotation positioning block through the fixing pins, the protective absorption sleeve includes an anti-collision absorption plate, the back of the anti-collision absorption plate is fixedly connected with a fixed plate by bolts, the two anti-collision rods and the rotation positioning block are both located between the anti-collision absorption plate and the fixed plate, and the anti-collision absorption plate and the fixed plate are both integrally formed with two limiting plates on the side opposite to the fixed plate, and the four limiting plates are respectively located on the front and back sides of the opposite sides of the two positioning blocks.

[0007] Preferably, the anti-collision absorption plate has an arc shape in a top view, and a plurality of absorption cavities are provided on the anti-collision absorption plate.

[0008] Preferably, a rubber absorption pad is fixedly connected to the back side of the fixing plate.

[0009] Preferably, the ends of the two anti-collision rods that are away from each other are each provided with a strip groove.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] 1. This scheme measures the position spacing of the anti-collision beams installed on the side door of the vehicle, and then rotates the rotating positioning block to drive the two connecting threaded rods to rotate and adjust the spacing between the two anti-collision bars, and then allows the rotating positioning block to be in a fixed position. After the distance adjustment is completed, the two positioning blocks are pulled out from one end of the anti-collision bar and fixed with the rotating positioning block. The sliding connection between the positioning support rod and the reinforcing cavity is used to limit the rotation of the rotating positioning block, thereby fixing the position between the two anti-collision bars, and the two anti-collision bars are used to play the role of anti-collision beams, and the reinforcing cavity improves the impact resistance of the anti-collision bar. The positioning support rod and the connecting threaded rod are used to increase the strength of the connection between the two anti-collision bars, and then the protective absorption sleeve is used to further protect the connection between the two anti-collision bars. The protective absorption sleeve can absorb and buffer most of the impact force to improve the deformation resistance of the anti-collision structure. Through its adjustable nature, it can be adjusted according to the size of the vehicle side door to be installed, so as to facilitate installation and use, with a wider range of applications. The maintenance point can be pre-stored so that it can be used directly, and the side door of the repaired vehicle can be repaired and used in time, which is suitable for popularization and use.

[0012] 2. In this solution, the engagement of the positioning block with the rotating positioning block can limit the rotation of the rotating positioning block, thereby preventing the rotation of the connecting threaded rod from causing a change in the distance between the two anti-collision rods.

[0013] 3. In this solution, four fixing pins are used to insert and fix the positions of the two positioning blocks and the rotating positioning block, so as to avoid the positioning blocks and the rotating positioning blocks from falling off due to the sliding connection between the positioning support rod and the reinforcing cavity and fail to play a limiting effect.

[0014] 4. In this solution, the front anti-collision absorption plate can first come into contact with the impact of the outside of the vehicle, thereby buffering and absorbing the impact force to form a first protective layer, which can protect the connection between the two anti-collision bars to a certain extent. When the first protective layer is broken, the anti-collision bar and the fixed plate are used to support the anti-collision bar to form a second protective layer, which can effectively reduce the impact during the collision, thereby avoiding the overall deformation of the side door from compressing the interior of the vehicle. The four limiting plates can limit the positions of the anti-collision absorption plate and the fixed plate on the two anti-collision bars to avoid the failure of the anti-collision effect due to misalignment.

[0015] 5. In this solution, the arc-shaped anti-collision absorption plate has a better effect of buffering and absorbing impact force, and the impact absorption effect of the anti-collision absorption plate can be further improved by using the absorption cavity.

[0016] 6. In this solution, the rubber absorption pad can isolate the fixing plate from the side door body. When the fixing plate is deformed, the rubber absorption pad can have a certain damping effect.

[0017] 6. This solution facilitates the installation and use of the anti-collision rod and the side door body through the strip groove. BRIEF DESCRIPTION OF THE DRAWINGS

By measuring the position spacing of the anti-collision beam installed on the vehicle side door, the rotating positioning block 5 is rotated to drive the two connecting threaded rods 4 to rotate and adjust the spacing between the two anti-collision bars 3, and then the rotating positioning block 5 is placed in a fixed position. After the distance adjustment is completed, the two positioning blocks 7 are pulled out from one end of the anti-collision bar 3 and fixed with the rotating positioning block 5. The sliding connection between the positioning support rod 8 and the reinforcing cavity 6 is used to limit the rotation of the rotating positioning block 5, so as to fix the position between the two anti-collision bars 3, and the two anti-collision bars 3 play the role of anti-collision beams, and the reinforcing cavity 6 improves the impact resistance of the anti-collision bar 3. 8 and the connecting threaded rod 4 increase the strength of the connection between the two anti-collision rods 3, and then the protective absorption sleeve 9 further protects the connection part between the two anti-collision rods 3, and the protective absorption sleeve 9 can absorb and buffer most of the impact force to improve the deformation resistance of the anti-collision structure, and through its adjustable nature, it can be adjusted according to the size of the side door of the vehicle to be installed, so as to facilitate installation and use, and has a wider range of applications. It can repair the side door of the maintenance vehicle in time and is suitable for promotion and use. The front view shape of the rotating positioning block 5 is a cross shape, and the shape of the two positioning blocks 7 is C-shaped. The opposite sides of the two positioning blocks 7 are engaged with the rotating positioning block 5, and the engagement of the positioning block 7 with the rotating positioning block 5 can limit the rotation. The rotation of the dynamic positioning block 5 prevents the spacing between the two anti-collision bars 3 from changing due to the rotation of the connecting threaded rod 4. Four fixing pins 10 are inserted into the two positioning blocks 7. The bottom ends of the four fixing pins 10 sequentially penetrate the rotating positioning block 5 and the positioning block 7 and extend to the inside of the rotating positioning block 5. The two positioning blocks 7 are fixedly connected to the rotating positioning block 5 through the fixing pins 10. The positions between the two positioning blocks 7 and the rotating positioning block 5 are plugged and fixed by the four fixing pins 10 to prevent the positioning block 7 and the rotating positioning block 5 from falling off due to the sliding connection between the positioning support rod 8 and the reinforcing cavity 6. The protective absorption sleeve 9 includes an anti-collision absorption plate 901. The back of the anti-collision absorption plate 901 is fixedly connected to a fixing plate 902 by bolts.The two anti-collision rods 3 and the rotating positioning block 5 are both located between the anti-collision absorption plate 901 and the fixed plate 902. The anti-collision absorption plate 901 and the fixed plate 902 are both integrally formed with two limiting plates 903 on the opposite side. The four limiting plates 903 are respectively located on the front and back sides of the two positioning blocks 7. The anti-collision absorption plate 901 on the front side can first contact the impact of the outside of the vehicle, thereby buffering and absorbing the impact force to form a first protective layer, which can protect the connection between the two anti-collision rods 3 to a certain extent. When the first protective layer is broken, the anti-collision rod 3 and the fixed plate 902 are used to support the anti-collision rod 3 to form a second protective layer, which can effectively reduce the impact during the collision, thereby avoiding the overall deformation of the side door from compressing the interior of the vehicle. The four limiting plates 903 can limit the positions of the anti-collision absorption plate 901 and the fixed plate 902 on the two anti-collision rods 3 to avoid the failure of the anti-collision effect due to misalignment.

[0031] Furthermore, the top view shape of the anti-collision absorption plate 901 is arc-shaped, and a plurality of absorption cavities 11 are provided on the anti-collision absorption plate 901. The arc-shaped anti-collision absorption plate 901 has a better effect of buffering and absorbing impact force. The absorption cavity 11 can further improve the impact absorption effect of the anti-collision absorption plate 901.

[0032] Furthermore, a rubber absorption pad 12 is fixedly connected to the back of the fixing plate 902. The rubber absorption pad 12 can isolate the fixing plate 902 from the side door body 1. When the fixing plate 902 is deformed, the rubber absorption pad 12 can have a certain damping effect.

[0033] Furthermore, a strip groove 13 is formed at one end of the two anti-collision bars 3 which are far away from each other, and the strip groove 13 facilitates the installation and use of the anti-collision bars 3 and the side door body 1.

[0034] Working principle: by measuring the position spacing of the anti-collision beam installed on the vehicle side door, the rotating positioning block 5 is rotated to drive the two connecting threaded rods 4 to rotate and adjust the spacing between the two anti-collision bars 3, and then the rotating positioning block 5 is placed in a fixed position. After the distance adjustment is completed, the two positioning blocks 7 are pulled out from one end of the anti-collision bar 3. The engagement of the positioning block 7 and the rotating positioning block 5 can limit the rotation of the rotating positioning block 5 to avoid the spacing between the two anti-collision bars 3 changing due to the rotation of the connecting threaded rod 4. The sliding connection between the positioning support rod 8 and the reinforcing cavity 6 is used to limit the rotation of the rotating positioning block 5, thereby fixing the position between the two anti-collision bars 3. The positions between the two positioning blocks 7 and the rotating positioning block 5 are plugged and fixed by four fixing pins 10 to avoid the positioning block 7 and the rotating positioning block 5 falling off due to the sliding connection between the positioning support rod 8 and the reinforcing cavity 6. The two anti-collision bars 3 are used to play the role of anti-collision beams, and the reinforcing cavity 6 improves the impact resistance of the anti-collision bar 3. The strength of the connection between the two anti-collision bars 3 is increased. The front anti-collision absorption plate 901 can first contact the impact of the outside of the vehicle, so as to buffer and absorb the impact force to form a first protective layer, which can protect the connection between the two anti-collision bars 3 to a certain extent. When the first protective layer is broken, the anti-collision bar 3 and the fixing plate 902 are used to support the anti-collision bar 3 to form a second protective layer, which can effectively reduce the impact during the collision, thereby avoiding the overall deformation of the side door from compressing the interior of the vehicle. The four limiting plates 903 can limit the positions of the anti-collision absorption plate 901 and the fixing plate 902 on the two anti-collision bars 3 to avoid the failure of the anti-collision effect due to misalignment. The protective absorption sleeve 9 can absorb and buffer most of the impact force to improve the deformation resistance of the anti-collision structure. The scheme can be adjusted according to the size of the vehicle side door to be installed through its adjustable nature, so as to facilitate installation and use. It has a wider range of application and can repair the side door of the maintenance vehicle in time, which is suitable for promotion and use.

[0035] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
