Description

Technical Field

[0001] The utility model relates to the technical field of automobile hatches, in particular to an anti-collision frame for automobile hatches. Background Art

[0002] With the rapid development of the automobile industry, the level of process technology is increasing day by day. The balance between performance improvement and lightweight has become a key issue to promote the progress of the automobile industry. One of the important parameters in vehicle design is how to more safely protect the driver and passengers from collision during vehicle collision and reduce the head, rib and pelvic injuries of the driver and passengers during side collision.

[0003] Based on the above, the existing method of increasing the anti-collision ability of automobile hatches is mainly to increase the material thickness of the door outer panel, thereby increasing the door's own stiffness, thereby improving the overall anti-collision ability. However, this will greatly increase the overall weight of the hatch, and the hatch can only absorb the force generated by the impact through the deformation of its own internal frame, and the anti-collision ability is poor. Utility Model Content

[0004] 1. Technical Problems to be Solved by the Utility Model

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anti-collision frame for a car door, which has the function of increasing the anti-collision ability of the car door.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] The invention discloses an anti-collision frame for a car door, which comprises a door shell and a door frame. The door shell is internally connected to the door frame which can support and reinforce the door shell.

[0009] As an optimization, the door frame includes a reinforcing rod, an anti-collision beam and a buffer mechanism. The reinforcing rod and the anti-collision beam are installed on the side of the door frame close to the door outer shell. The outer sides of the reinforcing rod and the anti-collision beam are in contact with the door outer shell. The inner sides of the reinforcing rod and the anti-collision beam are connected to the buffer mechanism, and the bottom of the buffer mechanism is connected to the door frame.

[0010] As an optimization, the buffer mechanism includes a base plate, a hydraulic buffer, a contact plate, a deceleration member and a buffer airbag. Hydraulic buffers are installed on both sides of the top of the base plate. The tops of the two hydraulic buffers are connected to contact plates. The tops of the contact plates are in contact with the reinforcing rods and anti-collision beams. A deceleration member is installed between the contact plate and the base plate. The deceleration member is symmetrically arranged in two groups. A buffer airbag connected to the base plate is installed between the two groups of deceleration members.

[0011] As an optimization, a support plate is installed inside the contact plate, and the support plate is a triangular structure with an equidistant array.

[0012] As an optimization, the deceleration component includes a connecting seat, a push rod, a push block, a push rod, a deceleration cylinder and a limit strip. A push rod is rotatably engaged with the connecting seat through a rotating shaft. The other end of the push rod is connected to the push block. The front end of the push block is connected to a push rod. The other end of the push rod is slidably engaged with the deceleration cylinder. There are limit strips slidably engaged on both sides of the push block.

[0013] As an optimization, a plurality of rubber pads are arranged in an equidistant array inside the reduction cylinder.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] (1) The utility model is an anti-collision frame for a car door. By installing a reinforcing rod and an anti-collision beam on the door frame and contacting the door shell, the support strength of the door frame can be increased. When the door shell is hit, it will first contact the reinforcing rod and the anti-collision beam to bear the impact force generated.

[0017] (2) The utility model is an anti-collision frame for a car door. A buffer mechanism in contact with a reinforcing rod and an anti-collision beam is installed on the door frame. The contact plate is squeezed and moves downward to squeeze the hydraulic buffer in contact with the reinforcing rod. The hydraulic damping in the hydraulic buffer can buffer the contact plate, so that the impact force will not be further transmitted downward to cause damage to the door frame.

[0018] (3) The utility model provides an anti-collision frame for a car hatch. When the contact plate is pressed downward, the connecting seat connected to it will be driven to move downward together. The connecting seat drives the push rod to move and push the push block forward. The push rod at the front end of the push block contacts the rubber pad in the reduction cylinder. The elasticity of the rubber pad slows down the movement of the contact plate. At the same time, because the push rod contacts the buffer airbag when pressed downward, the buffer airbag and the rubber pad cooperate to play a double buffering and deceleration role for the downward movement of the contact plate, which can better buffer and unload the impact force on the hatch, thereby protecting the service life of the hatch frame.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] See also Figure 1-Figure 6 A collision-proof frame for a car door comprises a door shell 1 and a door frame 2. The door shell 1 is internally connected to the door frame 2 for supporting and reinforcing the door shell 1.

[0029] In this embodiment, the door frame 2 includes a reinforcing rod 31, an anti-collision beam 32 and a buffer mechanism 33. The reinforcing rod 31 and the anti-collision beam 32 are installed on the side of the door frame 2 close to the door shell 1. The outer sides of the reinforcing rod 31 and the anti-collision beam 32 are in contact with the door shell 1, which can increase the supporting strength of the door frame 2. When the door shell 1 is hit, it will first contact the reinforcing rod 31 and the anti-collision beam 32 to bear the impact force generated. The inner side of the reinforcing rod 31 and the anti-collision beam 32 is connected to the buffer mechanism 33, and the bottom of the buffer mechanism 33 is connected to the door frame 2. The buffer mechanism 33 can buffer the reinforcing rod 31 and the anti-collision beam 32.

[0030] In this embodiment, the buffer mechanism 33 includes a base plate 11, a hydraulic buffer 12, a contact plate 13, a deceleration member 14 and a buffer airbag 15. Hydraulic buffers 12 are installed on both sides of the top of the base plate 11. The tops of the two hydraulic buffers 12 are connected to the contact plates 13. The tops of the contact plates 13 are in contact with the reinforcing rod 31 and the anti-collision beam 32. The deceleration member 14 is installed between the contact plate 13 and the base plate 11. The deceleration member 14 is symmetrically arranged in two groups. A buffer airbag 15 connected to the base plate 11 is installed between the two groups of deceleration members 14. The buffer airbag 15 can buffer the deceleration member 14 when the deceleration member 14 moves downward due to impact force.

[0031] In this embodiment, a support plate 131 is installed inside the contact plate 13. The support plate 131 is an equidistant array triangular structure. The triangular structure has the characteristics of high strength and stability, which can increase the strength of the contact plate 13 and make the contact plate 13 less likely to break after being squeezed and impacted by the reinforcing rod 31 and the anti-collision beam 32.

[0032] In this embodiment, the speed reducer 14 includes a connecting seat 21, a push rod 22, a push block 23, a push rod 24, a speed reduction cylinder 25 and a limit strip 26. The top of the connecting seat 21 is connected to the contact plate 13. The connecting seat 21 is rotatably equipped with a push rod 22. The other end of the push rod 22 is connected to the push block 23. The front end of the push block 23 is connected to a push rod 24. The other end of the push rod 24 is slidably engaged with the speed reduction cylinder 25. The speed reduction cylinder 25 is connected to the hydraulic buffer 12. The two sides of the push block 23 are slidably engaged with the limit strips 26. The limit strips 26 are located on the bottom plate 11, which can limit the movement of the push block 23 and prevent the push block 23 from shifting during movement.

[0033] In this embodiment, there are a number of rubber pads 251 arranged at equal distances inside the reduction cylinder 25. The rubber pads 251 can contact the push rod 24 due to the elasticity of the rubber material. When the push rod 24 moves forward driven by the push rod 22 and the push block 23, it will contact the number of rubber pads 251, and the elasticity of the rubber pads 251 will slow down the movement of the push rod 24.

[0034] Working principle: When the vehicle door is hit during driving, the reinforcing rod 31 and the anti-collision beam 32 on the door frame 2 can increase the supporting strength of the door frame 2 by contacting the door shell 1. When the vehicle door is hit, it will first contact the reinforcing rod 31 and the anti-collision beam 32 to bear the impact force. When the reinforcing rod 31 and the anti-collision beam 32 are hit, they will squeeze the contact plate 13 inwardly. After being squeezed, the contact plate 13 will move downward to squeeze the hydraulic buffer 12 in contact with it. With the help of the hydraulic damping in the hydraulic buffer 12, the contact plate 13 can be buffered, so that the impact force will not be further transmitted downward to cause damage to the door frame 2.

[0035] When the contact plate 13 is pressed downward, it will drive the connecting seat 21 connected to it to move downward together, and drive the push rod 23 to move together through the connecting seat 21. With the help of the downward movement of the push rod 23, the push block 23 is pushed forward. The push rod 24 located at the front end of the push block 23 will contact several rubber pads 251 inside the reduction cylinder 25 when it is pushed forward. The elasticity of the rubber pads 251 can slow down the movement of the push rod 24. At the same time, because the push rod 22 will contact the buffer airbag 15 when it is pressed downward, the rubber pad 251 and the buffer airbag 15 can play a double buffering and deceleration role on the downward movement of the contact plate 13, which can better buffer and unload the impact force exerted on the cabin door.
