Description

Technical Field

[0001] This invention relates to the field of anti-collision beam technology, and more specifically to an anti-collision beam assembly and its vehicle. Background Technology

[0002] A crash beam is a device used to absorb collision energy when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can effectively absorb collision energy when a vehicle is involved in a low-speed collision, minimizing the damage to the longitudinal beams of the vehicle body from the impact force. This is how it plays its role in protecting the vehicle.

[0003] For example, the invention patent disclosed in publication number CN209795397U discloses a front bumper beam assembly structure and its vehicle. The front bumper beam assembly structure includes a front bumper beam body and an energy-absorbing box. The front bumper beam body has a left side portion, a right side portion, and a central part with an arc shape. The left side portion and the right side portion extend along the tangential direction at both ends of the central part. The inner wall of the left side portion and the inner wall of the right side portion are connected to the front end face of the energy-absorbing box, and the connecting surface formed is a flat inclined surface.

[0004] Although the aforementioned anti-collision beams can perform protective energy absorption operations during vehicle collisions, when a vehicle encounters a minor or moderate collision, if the front of the anti-collision beam is crumpled and damaged, the entire anti-collision beam needs to be replaced, resulting in significant losses. At the same time, the installation of a single anti-collision beam is insufficient in terms of overall protection for the vehicle, reducing the vehicle's safety performance. Therefore, there is an urgent need for an anti-collision beam assembly to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a crash beam assembly and its vehicle, which provides good protection for the vehicle and is easy to replace and maintain.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A crash beam assembly includes a buffer device for cushioning and absorbing energy, a protective limiting device fixedly installed at the front of the buffer device for protection, and a detachable protective device disposed on the inner end face of the protective limiting device for cushioning.

[0008] A detachable protective device is fixedly snapped onto the inner end face of the protective limiting device. The detachable protective device includes an outer anti-collision beam housing for support. The inner end face of the outer anti-collision beam housing is provided with positioning slots that are evenly spaced vertically. A rubber protective pad is fixedly provided on the front end face of the outer anti-collision beam housing.

A connecting base for connection is fixedly installed on the rear end face of the energy-absorbing box housing, and a mounting plate for positioning is slidably engaged on the inner end face of the energy-absorbing box housing. Three sets of guide slide shafts are symmetrically arranged on the inner end face of the mounting plate, and two sets of positioning slides for guidance are arranged on the side of the inner end face of the mounting plate. A spring retainer is arranged on the inner end face of the positioning slide and coaxial with the guide slide shaft.

[0010] Preferably, the protective limiting device includes a hexagonal locking plate rotatably engaged at the center of the rear end face of the inner anti-collision beam housing, and a bidirectional screw symmetrically arranged on the outer end face of the hexagonal locking plate. A limiting slot for limiting is formed at the center of the front end face of the inner anti-collision beam housing, and a fixing groove for positioning is symmetrically formed on the outer end face of the inner anti-collision beam housing. The upper and lower parts of the inner anti-collision beam housing are slidably engaged with the limiting plates, and plug-in locking shafts are evenly and equidistantly arranged on the upper end face of the limiting plates. A spring guide ring is arranged on the lower end face of the limiting plates at the coaxial position with the plug-in locking shafts. A threaded slide is fixedly installed at the center of the inner end face of the limiting plates.

[0011] Preferably, the outer anti-collision beam housing is adapted to the limiting slot, and the detachable protective device is slidably engaged with the inner end face of the inner anti-collision beam housing through the adaptation of the outer anti-collision beam housing to the limiting slot.

[0012] Preferably, the bottom of the spring guide ring is fixedly connected to the bottom wall of the fixed slide groove, the plug-in pin is adapted to the positioning slot, and the limiting plate is fixedly engaged with the outer anti-collision beam housing through the plug-in pin and the positioning slot.

[0016] Compared with the prior art, the present invention provides a crash beam assembly and its vehicle, which adopts a dual protection design of a detachable protective device and a protective limiting device. At the same time, the detachable protective device and the protective limiting device are quick-removable, which can not only improve the external protection performance of the vehicle, but also facilitate the selective replacement of the detachable protective device and the protective limiting device according to the degree of damage in the vehicle collision, thereby improving the economic practicality of the crash beam assembly.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 As shown, the present invention provides two technical solutions:

[0029] Example 1:

[0030] A crash beam assembly includes a buffer device 2 for buffering and energy absorption, a protective limiting device 3 fixedly installed at the front of the buffer device 2 for protection, and a detachable protective device 1 disposed on the inner end face of the protective limiting device 3 for buffering.

[0031] The detachable protective device 1 is fixedly snapped onto the inner end face of the protective limiting device 3. The detachable protective device 1 includes an outer anti-collision beam housing 12 for support. The inner end face of the outer anti-collision beam housing 12 is provided with positioning slots 11 that are evenly spaced from top to bottom. A rubber protective pad 13 is fixedly provided on the front end face of the outer anti-collision beam housing 12. Protective partitions 14 are evenly spaced on the outer end face of the rubber protective pad 13.

[0032] The buffer device 2 includes an energy-absorbing box housing 26 for buffering. A connecting base 25 for connection is fixedly installed on the rear end face of the energy-absorbing box housing 26, and a mounting plate 22 for positioning is slidably engaged on the inner end face of the energy-absorbing box housing 26. Three sets of guide slide shafts 23 are symmetrically arranged on the inner end face of the mounting plate 22. Two sets of positioning slides 24 for guidance are arranged on the side of the inner end face of the mounting plate 22, and a spring retainer 21 is arranged on the inner end face of the positioning slide and coaxial with the guide slide shaft 23.

[0033] The protective limiting device 3 includes a hexagonal locking plate 39 rotatably engaged at the middle of the rear end face of the inner anti-collision beam housing 31, and a bidirectional screw 35 symmetrically arranged on the outer end face of the hexagonal locking plate 39. A limiting slot 37 for limiting is opened at the center of the front end face of the inner anti-collision beam housing 31, and a fixing groove 36 for positioning is symmetrically opened on the outer end face of the inner anti-collision beam housing 31. Limiting plates 32 are slidably engaged at both the upper and lower parts of the inner anti-collision beam housing 31. Insertion pins 33 are evenly and equidistantly arranged on the upper end face of the limiting plates 32. A spring guide ring 38 is arranged on the lower end face of the limiting plates 32 and coaxially with the insertion pins 33. A threaded slide block 34 is fixedly installed at the center of the inner end face of the limiting plates 32.

[0034] The outer anti-collision beam housing 12 is adapted to the limiting slot 37, and the detachable protective device 1 is slidably engaged with the inner end face of the inner anti-collision beam housing 31 by adapting the outer anti-collision beam housing 12 to the limiting slot 37, which can effectively improve the accuracy and stability of the subsequent alignment and connection between the detachable protective device 1 and the protective limiting device 3.

[0035] The bottom of the spring guide ring 38 is fixedly connected to the bottom wall of the fixed slide groove 36, and the plug-in pin 33 is adapted to the positioning slot 11. The limiting plate 32 is adapted to the positioning slot 11 through the plug-in pin 33 and then fixedly engaged with the outer anti-collision beam housing 12. The spring guide ring 38 can provide the limiting plate 32 with the spring force to reset, preventing it from disengaging when the threaded slide 34 and the bidirectional screw 35 are completely disengaged.

[0036] The inner end face of the connecting base 25 is slidably engaged with the mounting plate 22 via the guide slide shaft 23, and the top face of the spring retainer 21 is fixedly connected to the inner wall of the connecting base 25. The three sets of guide slide shafts 23 can ensure axial displacement of the detachable protective device 1 and the protective limiting device 3 when impacted, thereby improving the stability of impact buffering. At the same time, the three sets of spring retainers 21 can not only improve the stability of buffering, but also facilitate the subsequent reset of the detachable protective device 1 and the protective limiting device 3.

[0037] The hexagonal clamping plate 39 is adapted to the threaded slide block 34 via the bidirectional screw 35 and then threadedly connected to the limiting clamping plate 32. This allows the hexagonal clamping plate 39 to simultaneously drive the two sets of limiting clamping plates 32 to rise or fall via the two sets of bidirectional screws 35, thereby improving the stability of the positioning and limiting of the outer anti-collision beam shell 12.

[0038] Working principle: When in use, if the vehicle is subjected to an external collision, it is necessary to replace the detachable protective device 1 or the protective limiting device 3. At this time, the user can position the wrench on the outside of the hexagonal clamp 39, and then rotate the hexagonal clamp 39 with the external wrench. At this time, the hexagonal clamp 39 can drive the two sets of bidirectional screws 35 on the upper part to rotate. The two sets of bidirectional screws 35 can be connected to the threaded slide 34 through the thread, and simultaneously drive the two sets of limiting clamps 32 to move outward, thereby releasing the limiting of the insertion clamp 33 on the positioning slot 11. This makes it convenient for the user to quickly replace the outer anti-collision beam housing 12 and the rubber protective pad 13. At the same time, the user can use external tools to disassemble the connecting piece between the inner anti-collision beam housing 31 and the mounting clamp 22, which facilitates the subsequent replacement of the protective limiting device 3. The dual protection of the detachable protective device 1 and the protective limiting device 3 can effectively improve the safety of the front of the vehicle.

[0039] Example 2:

[0040] A vehicle includes a connecting seat for connecting to a connecting base 25. The connecting seat is fixedly connected to the connecting base 25 by fixing bolts. The connecting seat can be connected to the connecting base 25 by bolts or other connecting parts, which facilitates quick positioning and disassembly.
