Description

Technical Field

[0001] The present invention relates to the technical field of automotive bumpers, and specifically to a high-protection automotive bumper assembly. Background Art

[0002] When a vehicle collides, the bumper assembly can absorb and disperse most of the impact energy, reduce the impact force on the vehicle body structure and passengers during the collision, thereby protecting the safety of the people inside the vehicle and reducing the occurrence of casualty accidents. The automotive bumper assembly includes a bumper body, mounting parts, elastic card seats, decorative parts, and strengthening structures. Among them, the bumper body part is usually made of materials such as plastic, fiberglass, or metal. Its shape and design match the overall shape of the vehicle. It can directly bear and disperse the impact force during a vehicle collision, protecting the vehicle body structure and passenger safety.

[0003] With the improvement of vehicle intelligence, a variety of electronic devices are correspondingly installed on the bumper body, such as cameras, millimeter-wave radars, lidars, etc. These electronic components are of high value. Therefore, new standards are also proposed for the protection ability of automotive bumpers. In some low-speed collision scenarios, such as following a vehicle, parking in a parking space, and lane change, once a squeezing collision occurs, due to the low speed, small collision amplitude, and the bumper body having a certain toughness, from the outside observation, the bumper body is only slightly damaged. However, most of the electronic devices are rigidly connected to the bumper body. Under the impact of the collision, the electronic devices may be damaged due to the collision, and the cost of the electronic devices is much higher than that of plastic parts such as the bumper body, resulting in a relatively high maintenance cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-protection automotive bumper assembly to solve the deficiencies in the above-mentioned prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-protection automotive bumper assembly includes a bumper body, a collision avoidance steel beam, and an electronic installation assembly. The electronic installation assembly includes a bracket, an outer sleeve, an inner sliding sleeve, an electronic component, a release mechanism, and an elastic part. The outer sleeve is fixedly installed on the collision avoidance steel beam through the bracket. One end of the inner sliding sleeve is slidably inserted into the outer sleeve, and the other end of the inner sliding sleeve protrudes outside the bumper body. The electronic component is slidably connected in the inner sliding sleeve. The release mechanism is used to fix the inner sliding sleeve and the electronic component. The release mechanism has an unlocking position. After the inner sliding sleeve is squeezed, the inner sliding sleeve and the electronic component are displaced synchronously and squeeze the release mechanism to the unlocking position. The release mechanism is unlocked, and the electronic component moves under the elastic force of the elastic part so that the electronic component disengages from the inner sliding sleeve.

[0006] Preferably, a limiting disk is arranged at the end of the inner sliding sleeve, the limiting disk abuts against the bumper body, and an inner fixing block is arranged inside the inner sliding sleeve.

[0007] Preferably, the elastic part includes an end cover and a first elastic member. The end cover is fixedly installed outside the electronic component, the first elastic member is installed on the end cover, and the other end of the first elastic member abuts against the inner fixing block. The first elastic member exerts a thrust force on the inner sliding sleeve towards the bumper body.

[0008] Preferably, a positioning ring is arranged in the middle of the electronic component, and the first elastic member passes through the positioning ring.

[0009] Preferably, the release mechanism includes a T-shaped rod, a flipping sleeve, a second elastic member, a stop block, a track groove and a guide shaft. The T-shaped rod is fixedly installed at the end of the outer sleeve, the second elastic member is movably sleeved outside the T-shaped rod, the flipping sleeve is sleeved outside the T-shaped rod, and the stop block is fixed on the flipping sleeve.

[0010] Preferably, the thrust forces exerted by the first elastic member and the second elastic member on the electronic component are in opposite directions.

[0011] Preferably, the elastic member part further includes a rotation prevention groove, the rotation prevention groove is formed in the outer sleeve, and the end cover is adapted to the rotation prevention groove.

[0012] Preferably, an avoidance opening is formed in the anti-collision steel beam, and the position of the avoidance opening corresponds to the position of the electronic installation assembly.

[0013] In the above technical solution, for a high-protection automobile bumper assembly provided by the present invention, when being squeezed, first, the inner sliding sleeve and the electronic component move synchronously and squeeze the stop block. During the displacement of the stop block, it is flipped passively, and the stop block will disengage from the electronic component. Under the elastic force of the elastic part, the electronic component will disengage from the inner sliding sleeve. In this way, when being squeezed and collided, the original integral rigid connection structure is changed into a split structure that can be actively disengaged. Through the active disengagement of the electronic component, the electronic component is maximally protected to reduce the subsequent repair cost. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figure 1-12 , a highly protective automobile bumper assembly provided by an embodiment of the present invention includes a bumper body 1, a crash beam 3, and an electronic installation assembly 2. The electronic installation assembly 2 includes a bracket 21, an outer sleeve 22, an inner sliding sleeve 23, an electronic component 24, a release mechanism 25, and an elastic part. The outer sleeve 22 is fixedly installed on the crash beam 3 through the bracket 21. One end of the inner sliding sleeve 23 is slidably inserted into the outer sleeve 22, and the other end of the inner sliding sleeve 23 protrudes to the outside of the bumper body 1. The electronic component 24 is slidably connected in the inner sliding sleeve 23. The release mechanism 25 is used to fix the inner sliding sleeve 23 and the electronic component 24. The release mechanism 25 has an unlocking position. After the inner sliding sleeve 23 is squeezed, the inner sliding sleeve 23 and the electronic component 24 are displaced synchronously and squeeze the release mechanism 25 to the unlocking position. The release mechanism 25 is unlocked, and the electronic component 24 moves under the elastic force of the elastic part so that the electronic component 24 disengages from the inner sliding sleeve 23.

[0030] In the embodiment of the present invention, when the inner sliding sleeve 23 is squeezed, the inner sliding sleeve 23 will perform a displacement along its axial direction. The inner sliding sleeve 23 will exert a pressure on the release mechanism 25, and the release mechanism 25 will move synchronously with the inner sliding sleeve 23. At this time, under the elastic force of the elastic part, the electronic component 24 will also perform a displacement synchronously with the inner sliding sleeve 23. As the squeezing intensifies, the inner sliding sleeve 23 continues to displace so that the release mechanism 25 moves to the unlocking position. At the unlocking position, the release mechanism 25 is unlocked, and the electronic component 24 disengages from the inner sliding sleeve 23 under the elastic force of the elastic part. When being squeezed or impacted, the electronic component 24 actively disengages from the inner sliding sleeve 23 to reduce the damage it receives. The original integral rigid connection structure is transformed into a split structure that can actively disengage, which can maximize the protection of the electronic component 24 and reduce the subsequent repair cost.

[0031] In the embodiment of the present invention, please refer to Figure 3 and 5 , a limiting disk 231 is provided at the end of the inner sliding sleeve 23, the limiting disk 231 abuts against the bumper body 1, and an inner fixing block 232 is arranged inside the inner sliding sleeve 23.

[0032] The end of the inner sliding sleeve 23 penetrates through the bumper body 1. Under the extrusion of the release mechanism 25, the limit disc 231 also abuts against the inner wall of the bumper body 1 to ensure that the inner sliding sleeve 23 is in a stable state. When a collision occurs, first, the inner sliding sleeve 23 will be extruded, and then a certain displacement will be generated. When the end of the inner sliding sleeve 23 is flush with the bumper body 1, it is exactly at the release position. At this position, the release mechanism 25 is unlocked to ensure that the electronic component 24 can be separated.

[0033] In an embodiment of the present invention, please refer to Figure 3 and 5 The elastic part includes an end cap 241 and a first elastic member 242. The end cap 241 is fixedly installed outside the electronic component 24. The first elastic member 242 is installed on the end cap 241. The other end of the first elastic member 242 abuts against the inner fixing block 232, and the first elastic member 242 exerts a thrust force on the inner sliding sleeve 23 towards the bumper body 1.

[0034] The end cap 241 is fixedly installed on the electronic component 24, and the first elastic member 242 is installed on the end cap 241. When the electronic component 24 is inside the inner sliding sleeve 23, the other end of the first elastic member 242 will abut against the inner fixing block 232. After the electronic component 24 is installed in the inner sliding sleeve 23, the first elastic member 242 will be compressed. Therefore, the first elastic member 242 will exert a thrust force on the electronic component 24 towards the direction of the bumper body 1. Under normal conditions, due to the restriction of the release mechanism 25, the resilience of the first elastic member 242 is not enough to resist the pressure provided by the release mechanism 25. Therefore, the first elastic member 242 will be in a compressed state. And at the unlocking position, since the release mechanism 25 is separated from the electronic component 24, the first elastic member 242 will rebound to separate the electronic component 24 and the inner sliding sleeve 23.

[0035] In an embodiment of the present invention, please refer to Figure 3 and 5 A positioning ring 243 is provided in the middle of the electronic component 24, and the first elastic member 242 penetrates through the positioning ring 243.

[0036] The setting of the positioning ring 243 is used to limit the radial direction of the first elastic member 242, so that the first elastic member 242 expands and contracts along its own axial direction, reducing the assembly difficulty of the first elastic member 242.

[0037] In an embodiment of the present invention, please refer to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 10 、 Figure 11, the release mechanism 25 includes a T-shaped rod 251, a flipping sleeve 252, a second elastic member 253, a stop block 254, a track groove 2521, and a guide shaft 2522. The T-shaped rod 251 is fixedly installed at the end of the outer sleeve 22. The second elastic member 253 is movably sleeved outside the T-shaped rod 251. The flipping sleeve 252 is sleeved outside the T-shaped rod 251. The stop block 254 is fixed on the flipping sleeve 252.

[0038] A clearance opening 31 is formed on the anti-collision steel beam 3, and the position of the clearance opening 31 corresponds to the position of the electronic installation assembly 2.

[0039] Since the shape of the T-shaped rod 251 is set to be T-shaped, the end of the second elastic member 253 can abut against the end of the T-shaped rod 251, and the other end of the second elastic member 253 abuts against the flipping sleeve 252. The second elastic member 253 exerts a thrust on the flipping sleeve 252 in the direction towards the inner sliding sleeve 23. Under the elastic force of the second elastic member 253, the stop block 254 presses against the end faces of the inner sliding sleeve 23 and the electronic component 24, so that the limiting disc 231 provided on the inner sliding sleeve 23 presses against the bumper body 1. In this way, in the normal use state, through the pressing action of the bumper body 1 and the stop block 254, the stability of the position of the inner sliding sleeve 23 is ensured. Similarly, the electronic component 24 is respectively subjected to the pressing forces from the stop block 254 and the first elastic member 242, and the electronic component 24 is also fixed in the inner sliding sleeve 23 synchronously. When being collided and pressed, the inner sliding sleeve 23 will displace in the direction towards the release mechanism 25. During the displacement process, under the pressure, the stop block 254 will resist the elastic force generated by the second elastic member 253, and the stop block 254 and the flipping sleeve 252 will displace synchronously, and the second elastic member 253 will be compressed. During the displacement process of the flipping sleeve 252, the position of the guide shaft 2522 remains unchanged compared with the T-shaped rod 251, but the position of the guide shaft 2522 changes in the track groove 2521. The guide shaft 2522 will exert a torsion force on the track groove 2521, so that the flipping sleeve 252 will perform a synchronous flip during the displacement process. In this way, after the release mechanism 25 moves to the unlocking position, the stop block 254 will disengage from the end of the electronic component 24. At this time, without the obstruction of the stop block 254, the first elastic member 242 will rebound, and under the elastic force, the electronic component 24 will move in the direction towards the anti-collision steel beam 3. A clearance opening 31 is formed at the corresponding position of the anti-collision steel beam 3 for the moving path of the electronic component 24, and the electronic component 24 will smoothly enter the clearance opening 31. The hardness of the anti-collision steel beam 3 is much greater than that of the bumper body 1, which can play a better protective role.

[0040] A buffer layer can be provided at the position where the clearance opening 31 is located to reduce the impact when the electronic component 24 enters.

[0041] In another embodiment of the present invention, after being impacted, the bumper body 1 may not be damaged or only slightly damaged due to its strong toughness. When negotiating a settlement among car owners, the state of the internal electronic devices is not considered. After the accident handling is completed, problems with the internal electronic devices gradually emerge. Not only do the subsequent repair costs need to be borne by the car owner himself, but in today's highly intelligent cars, damage to the electronic component 24 may also cause safety accidents. In the present invention, as long as the collision and extrusion reach a certain degree, the electronic component 24 will disengage from the inner sliding sleeve 23. When negotiating a settlement, the car owner can judge the impact intensity suffered by the electronic installation assembly 2 by observing whether the electronic component 24 is inside the inner sliding sleeve 23. As long as the electronic component 24 disengages, it will necessarily involve subsequent inspection problems. Therefore, this problem needs to be considered during the negotiation to fully protect the interests of the car owner himself and improve the safety risk warning, so that the car owner can temporarily stop using intelligent functions such as assisted driving of the vehicle.

[0042] In an embodiment of the present invention, the thrust directions applied by the first elastic member 242 and the second elastic member 253 to the electronic component 24 are opposite.

[0043] Through the combined action of the first elastic member 242 and the second elastic member 253, the fixation of the electronic component 24 can be achieved to ensure the stability of the electronic component 24 during normal use. Moreover, only axial displacement can occur between the inner sliding sleeve 23 and the outer sleeve 22, and rotation is not allowed, so as to ensure the stability of the electronic component 24 after the inner sliding sleeve 23 is installed.

[0044] In an embodiment of the present invention, the elastic member portion further includes an anti-rotation groove 233, which is opened in the outer sleeve 22, and the end cap 241 is adapted to the anti-rotation groove 233.

[0045] The anti-rotation groove 233 is used to make way for the end cap 241 so that the electronic component 24 can be smoothly inserted into the inner sliding sleeve 23. And through the setting of the anti-rotation groove 233, the electronic component 24 can only move horizontally but not rotate inside the inner sliding sleeve 23, so as to ensure the stability of the electronic component 24 inside the inner sliding sleeve 23.

[0046] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
