The automobile bumper assembly includes the bumper body, mounting parts, elastic holders, decorative parts, and reinforcement structures. The bumper body is usually made of materials such as plastic, fiberglass or metal. Its shape and design match the overall shape of the car. When the vehicle collides, it can directly withstand and disperse the impact force to protect the vehicle body structure and passenger safety.

[0003] With the improvement of automobile intelligence, a variety of electronic devices are installed on the bumper body, such as cameras, millimeter-wave radars, laser radars, etc. These electronic parts are of high value, so new standards are also proposed for the protection capabilities of automobile bumpers. In some low-speed collision scenes, such as following a car, parking in a parking space, changing lanes, etc., once a squeeze collision occurs, due to the slow speed, small collision amplitude, and a certain toughness of the bumper body, the bumper body is only slightly damaged from the outside, but the electronic equipment is mostly rigidly connected to the bumper body. Under the impact of the collision, the electronic equipment may be damaged due to the collision, and the cost of the electronic equipment is much higher than that of plastic parts such as the bumper body, which results in a higher maintenance cost.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1-12A high-protection automobile bumper assembly provided by an embodiment of the present invention includes a bumper body 1, an anti-collision steel beam 3 and an electronic installation assembly 2, wherein 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 portion, wherein the outer sleeve 22 is fixedly installed on the anti-collision steel beam 3 through the bracket 21, one end of the inner sliding sleeve 23 is slidably inserted in the outer sleeve 22, and the other end of the inner sliding sleeve 23 protrudes to the outside of the bumper body 1, and the electronic component 24 is slidably connected in the inner sliding sleeve 23, and the release mechanism 25 is used to fix the inner sliding sleeve 23 and the electronic component 24, and 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 synchronously displaced 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 portion, so that the electronic component 24 is separated from the inner sliding sleeve 23.

[0019] In the embodiment of the present invention, when the inner sliding sleeve 23 is squeezed, the inner sliding sleeve 23 will be displaced along its axial direction, and the inner sliding sleeve 23 will apply a pressure to 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 be displaced synchronously with the inner sliding sleeve 23. As the squeezing intensifies, the inner sliding sleeve 23 continues to be displaced 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 is disengaged from the inner sliding sleeve 23 under the elastic force of the elastic part. When squeezed or impacted, the electronic component 24 is actively disengaged from the inner sliding sleeve 23 to reduce the damage to it. The original integrated rigid connection structure is transformed into a split structure that can be actively disengaged, which can maximize the protection of the electronic component 24 and reduce the subsequent repair cost.

[0020] In the embodiments of the present invention, please refer to Figure 3 and 5 In the embodiment, a limiting plate 231 is disposed at the end of the inner sliding sleeve 23 , the limiting plate 231 abuts against the bumper body 1 , and an inner fixing block 232 is disposed inside the inner sliding sleeve 23 .

[0021] The end of the inner sliding sleeve 23 passes through the bumper body 1. Under the extrusion of the release mechanism 25, the limit plate 231 also contacts 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, the inner sliding sleeve 23 will be squeezed first, and then a certain displacement will occur. When the end of the inner sliding sleeve 23 is flush with the bumper body 1, it is in the release position. At this position, the release mechanism 25 is unlocked to ensure that the electronic component 24 can be separated.

[0022] In the embodiments of the present invention, please refer to Figure 3 and 5 The elastic part includes an end cover 241 and a first elastic member 242. The end cover 241 is fixedly mounted on the outside of the electronic component 24. The first elastic member 242 is mounted on the end cover 241. The other end of the first elastic member 242 abuts against the inner fixed block 232. The first elastic member 242 applies a thrust toward the bumper body 1 to the inner sliding sleeve 23.

[0023] The end cover 241 is fixedly mounted on the electronic component 24, and the first elastic member 242 is mounted on the end cover 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 fixed 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 apply a thrust to the electronic component 24 in the direction of the bumper body 1. In a normal state, due to the limitation of the release mechanism 25, the rebound force 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. In the unlocked 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.

[0024] In the embodiments of the present invention, please refer to Figure 3 and 5 A positioning ring 243 is disposed in the middle of the electronic component 24 , and the first elastic member 242 passes through the positioning ring 243 .

[0025] The positioning ring 243 is used to limit the radial direction of the first elastic member 242 so that the first elastic member 242 can be moved along its own axial direction when being extended or retracted, thereby reducing the difficulty of assembling the first elastic member 242 .

[0026] In the embodiments of the present invention, please refer to Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig.10 , Fig.11 The release mechanism 25 includes a T-shaped rod 251, a flip 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 on the outside of the T-shaped rod 251, the flip sleeve 252 is sleeved on the outside of the T-shaped rod 251, and the stop block 254 is fixed on the flip sleeve 252.

[0027] The anti-collision steel beam 3 is provided with an escape opening 31 , and the position of the escape opening 31 corresponds to the position of the electronic installation assembly 2 .

[0028] Since the T-shaped rod 251 is in a T-shape, 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 flip sleeve 252. The second elastic member 253 applies a thrust to the flip sleeve 252 in the direction of the inner sliding sleeve 23. Under the elastic force of the second elastic member 253, the stop block 254 is pressed against the end surface of the inner sliding sleeve 23 and the electronic component 24, so that the limit plate 231 provided on the inner sliding sleeve 23 squeezes The inner sliding sleeve 23 is pressed on the bumper body 1. In this way, under normal use, the position of the inner sliding sleeve 23 is ensured to be stable under the extrusion of the bumper body 1 and the stopper 254. Similarly, the electronic component 24 is respectively subjected to the extrusion from the stopper 254 and the first elastic member 242. The electronic component 24 is also fixed in the inner sliding sleeve 23. When subjected to collision and extrusion, the inner sliding sleeve 23 will move toward the direction where the release mechanism 25 is located. During the displacement process, the stopper 254 will move under the pressure. To resist the elastic force generated by the second elastic member 253, the stop block 254 and the flip sleeve 252 are synchronously displaced, and the second elastic member 253 is compressed. During the displacement of the flip sleeve 252, the position of the guide shaft 2522 relative to the T-shaped rod 251 remains unchanged, while the position of the guide shaft 2522 in the track groove 2521 changes. The guide shaft 2522 applies a torsion force to the track groove 2521, so that the flip sleeve 252 is synchronously flipped during the displacement process. In this way, the release mechanism 25 moves to After the unlocking position, the stop block 254 will be disengaged 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 the electronic component 24 will move toward the direction of the anti-collision steel beam 3 under the action of the elastic force. A clearance opening 31 is opened at the anti-collision steel beam 3 corresponding to the moving path of the electronic component 24. 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.

[0029] A buffer layer may be provided at the position of the avoidance opening 31 to reduce the impact of the electronic component 24 during the movement.

[0030] In another embodiment of the present invention, after being hit, the bumper body 1 may not be damaged or only slightly damaged due to its own toughness. When the car owners negotiate to resolve the problem, the status of the internal electronic equipment is not taken into consideration. After the accident is handled, the problems of the internal electronic equipment are gradually exposed. Not only does the car owner need to bear the subsequent maintenance costs, but in today's highly intelligent automobiles, damage to the electronic components 24 may also cause safety accidents. In the present invention, as long as the collision and squeezing occur to a certain extent, the electronic components 24 will detach from the inner sliding sleeve 23. When negotiating to resolve the problem, the car owner can judge the impact intensity of the electronic installation assembly 2 by observing whether the electronic components 24 are in the inner sliding sleeve 23. As long as the electronic components 24 are detached, it will inevitably involve subsequent maintenance issues. In this way, this problem needs to be taken into consideration during the negotiation to fully protect the interests of the car owner and improve the safety risk warning, so that the car owner temporarily stops using the vehicle's assisted driving and other intelligent functions.

[0031] In the embodiment of the present invention, the thrusts applied by the first elastic member 242 and the second elastic member 253 to the electronic component 24 are in opposite directions.

[0032] Through the joint action of the first elastic member 242 and the second elastic member 253, the electronic component 24 can be fixed to ensure the stability of the electronic component 24 during normal use, and only axial displacement but no rotation can occur between the inner sliding sleeve 23 and the outer sleeve 22 to ensure the stability of the electronic component 24 after the inner sliding sleeve 23 is installed.

[0033] In an embodiment of the present invention, the elastic member further comprises a rotation-stopping groove 233 , the rotation-stopping groove 233 is provided in the outer sleeve 22 , and the end cover 241 is matched with the rotation-stopping groove 233 .

[0034] The anti-rotation groove 233 is used to make way for the end cover 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 laterally but not rotate in the inner sliding sleeve 23, so as to ensure the stability of the electronic component 24 in the inner sliding sleeve 23.

[0035] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. 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.
