Description

Technical Field

[0002] With the improvement of the intelligence level of new energy vehicles, the number of electronic control devices installed on the body is increasing, and the requirements for body integration are also getting higher and higher. At the same time, in order to increase the storage space of the vehicle and avoid electronic control devices occupying the storage box space of the vehicle, more electronic control devices are integrated and arranged at the lower end of the vehicle's storage box, such as high and low voltage charging system assemblies, active stabilizer bar controllers, high and low voltage converters, air suspension compressors, etc. Based on this design, higher requirements are placed on the vehicle's collision safety performance.

[0003] In traditional vehicles, from the outside to the inside, the vehicle is composed of structures such as the bumper assembly, the lower body anti-collision beam, the storage box assembly, and the subframe. The electronic control devices integrated at the lower end of the body storage box have limited protection when the vehicle is hit. There is a lack of energy-absorbing structure between the electronic control devices and the anti-collision beam, which is not conducive to the transmission of force. After being hit and squeezed, the electronic control devices are easily deformed, damaged, or fail, and even cause major safety accidents.

[0004] Therefore, it is necessary to provide an improved device protection apparatus to solve some or all of the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0041] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0043] like Figure 1 and Figure 2As shown, the device protection apparatus of the present application includes a connector 1 and an energy absorbing member 2. The connector 1 is provided with a device fixing portion 11 for mounting a device 10, and the energy absorbing member 2 is positioned adjacent to the device fixing portion 11. The energy absorbing member 2 has a first collision state and a second collision state. When the energy absorbing member 2 is in the first collision state, it absorbs energy and collapses. When the energy absorbing member 2 is in the second collision state, it moves toward the device fixing portion 11 to knock the device 10 off.

[0044] With such a configuration, when the device protection device is hit, on the one hand, the energy absorbing member 2 absorbs energy and collapses to reduce the impact force and reduce the degree of damage to the device 10; on the other hand, the energy absorbing member 2 moves to knock down the device 10, preventing the device 10 from being directly hit by external components such as the anti-collision beam and being squeezed and damaged, greatly reducing the maintenance cost of the device 10 and allowing the device 10 to be recycled.

[0045] In some embodiments, the energy absorbing member 2 is connected to the connector 1. When the energy absorbing member 2 is in the second collision state, the energy absorbing member 2 is separated from the connector 1 and moves toward the device fixing portion 11. The second collision state occurs after the first collision state. With this arrangement, the energy absorbing member 2 is first used to withstand the external impact force to absorb energy and collapse, preventing the energy absorbing member 2 from directly moving and knocking off the device 10 under the impact of a smaller impact force. At the same time, the energy absorbing member 2 absorbs energy and collapses, thereby reducing the impact force and minimizing damage to the device 10.

[0046] In some other embodiments, the first and second collision states occur simultaneously. Specifically, when the device protection device is impacted, the energy absorber 2 collapses while absorbing energy and simultaneously moves toward the device securing portion 11. This arrangement allows the device 10 connected to the device securing portion 11 to quickly fall off, thereby preventing other components, such as the anti-collision beam, from directly impacting the device 10 after the energy absorber 2 collapses and fails.

[0047] Further integration Figure 3 As shown, the connector 1 may further include a guide plate 12. The guide plate 12 is bent from the side of the device-mounting portion 11 facing away from the energy-absorbing member 2 and is used to guide the device 10 away from the device-mounting portion 11. To enhance the guiding effect of the guide plate 12, the angle A between the guide plate 12 and the device-mounting portion 11 is an obtuse angle.

[0048] Connector 1 includes an energy-absorbing member fixing portion 13 and multiple positioning shafts 14. Energy-absorbing member fixing portion 13 is located on the side of device fixing portion 11 facing away from guide plate 12 and is used to mount energy-absorbing member 2. Multiple positioning shafts 14 are provided on device fixing portion 11 and energy-absorbing member fixing portion 13, respectively. The positioning shafts 14 on device fixing portion 11 penetrate device 10, while the positioning shafts 14 on energy-absorbing member fixing portion 13 penetrate energy-absorbing member 2. This improves the efficiency of mounting device 10 and energy-absorbing member 2 on connector 1.

[0049] Further integration Figures 4 to 7 As shown, in some embodiments, the energy absorbing member 2 includes an energy absorbing box body 21, reinforcing vertical ribs 22, reinforcing horizontal ribs 23, and a reinforcement frame 24. The energy absorbing box body 21 is fixed to the energy absorbing member fixing portion 13 and includes a mounting portion 211, a connecting bracket 212, an upper side plate 213, a lower side plate 214, a left side plate 215, and a right side plate 216.

[0050] At least a portion of the mounting portion 211 is located on the upper side panel 213 of the energy absorbing box 21 and engages with the connector 1. Specifically, the mounting portion 211 engages with the energy absorbing member's fixed portion 13, and the positioning axis 14 located on the energy absorbing member's fixed portion 13 extends through the mounting portion 211. A connecting bracket 212 is secured to the lower side panel 214 of the energy absorbing box 21 and can be connected to the vehicle's bumper. A left side panel 215 and a right side panel 216 are both connected between the upper side panel 213 and the lower side panel 214, and are spaced apart along the left-right direction of the energy absorbing box 21.

[0051] It is worth noting that when the device protection device of the present application is installed on a vehicle, the up, down, left and right directions described in the device protection device are consistent with the up, down, left and right directions conventionally determined for a vehicle.

[0052] The mounting portion 211 includes a mounting hole 2111 and a relief cavity 2112. The mounting hole 2111 extends through the upper side plate 213 of the energy absorbing box body 21, while the relief cavity 2112 extends through the lower side plate 214 of the energy absorbing box body 21 and extends upward to the upper side plate 213 of the energy absorbing box body 21. The relief cavity 2112 communicates with the mounting hole 2111. To facilitate connection between the mounting portion 211 and the connector 1, the relief cavity 2112's projection overlaps the projection of the mounting hole 2111 along the vertical direction of the energy absorbing box body 21.

[0053] The mounting portion 211 is preferably connected to the connector 1 via a combination of bolts and nuts. Specifically, the positioning shaft 14 located on the energy absorber's fixing portion 13 passes through the mounting hole 2111 and the escape cavity 2112. The nut component is located within the escape cavity 2112 and is connected to the positioning shaft 14. Of course, the mounting portion 211 and connector 1 can also be connected via fasteners such as screws and rivets.

[0054] In order to reduce the friction noise between the mounting part 211 and the connecting part 1 and avoid the wear and failure of the mounting part 211, the device protection device can also include a seal 3 and a pressure ring 4, wherein the seal 3 is arranged around the mounting hole 2111, and the seal 3 is attached between the upper side plate 213 of the energy absorption box body 21 and the connecting part 1, and the pressure ring 4 is clamped on the inner wall of the mounting hole 2111.

[0055] Specifically, the seal 3 is a sealing foam, and a through hole is provided in the middle of the seal 3 to avoid the mounting hole 2111. When the energy absorbing box body 21 is fixed to the connector 1, the seal 3 is squeezed to reduce the friction noise between the energy absorbing box body 21 and the connector 1. The pressure ring 4 is preferably made of metal, and the fasteners used to fix the mounting portion 211 and the connector 1 pass through the pressure ring 4. This arrangement avoids direct contact between the fasteners and the inner wall of the mounting hole 2111, thereby preventing the mounting portion 211 from being worn and failing, and at the same time reduces the torque attenuation caused by the different materials of the energy absorbing box body 21 and the connector 1.

[0056] To facilitate the installation of the seal 3 on the mounting portion 211, the mounting portion 211 includes an inner convex ring 2113 and an outer convex ring 2114. The inner convex ring 2113 protrudes from the upper plate 213, and the mounting hole 2111 communicates with the inner convex ring 2113, with the projection of the mounting hole 2111 coinciding with the projection of the inner hole of the inner convex ring 2113. A portion of the pressure ring 4 is secured within the inner convex ring 2113. The outer convex ring 2114 protrudes from the upper plate 213 and surrounds the inner convex ring 2113. The seal 3 is sleeved within the inner convex ring 2113 and positioned within the outer convex ring 2114.

[0057] Two mounting portions 211 are provided. One mounting portion 211 has a circular mounting hole 2111 serving as a primary positioning hole, while the other mounting portion 211 has a waist-shaped mounting hole 2111 serving as a secondary positioning hole. The two mounting portions 211 of the energy absorbing box body 21 enhance the connection stability between the energy absorbing member 2 and the connector 1. Furthermore, the mounting holes 2111 improve the efficiency of the installation between the energy absorbing member 2 and the connector 1.

[0058] In some other embodiments, the mounting portion 211 may also be a snap-fit ​​structure such as a claw or a buckle protruding from the upper side plate 213 , and the energy absorbing box body 21 may be snap-fitted to the connector 1 .

[0059] Further integration Figure 8 and Figure 9 As shown, in some embodiments, vertical reinforcement ribs 22 and transverse reinforcement ribs 23 are connected to the inner wall of the energy absorption box body 21, and the vertical reinforcement ribs 22 and transverse reinforcement ribs 23 are arranged crosswise. Specifically, the vertical reinforcement ribs 22 are connected between the upper side panel 213 and the lower side panel 214, and the transverse reinforcement ribs 23 extend from the left side panel 215 to the right side panel 216 and can be connected to the vertical reinforcement ribs 22, the left side panel 215, and the right side panel 216 respectively. Along the vertical direction of the energy absorption box body 21, the avoidance cavity 2112 partially penetrates the vertical reinforcement ribs 22 and transverse reinforcement ribs 23.

[0060] Multiple vertical reinforcing ribs 22 and transverse reinforcing ribs 23 are provided, with the multiple vertical reinforcing ribs 22 spaced apart along the left-right direction of the energy absorbing box 21. Multiple transverse reinforcing ribs 23 are spaced apart along the top-bottom direction of the energy absorbing box 21. The thickness B of some vertical reinforcing ribs 22 is greater than the thickness C of the transverse reinforcing ribs 23. This arrangement improves the overall strength of the energy absorbing member 2 while achieving a lightweight design. In other embodiments, the thickness C of the transverse reinforcing ribs 23 may be greater than or equal to the thickness B of the vertical reinforcing ribs 22.

[0061] A reinforcement frame 24 is located within the energy-absorbing box 21 and is connected to the vertical and horizontal reinforcement ribs 22 and 23, respectively, to enhance the overall strength of the energy-absorbing element 2. Specifically, the reinforcement frame 24 is preferably constructed of metal or a high-strength composite material and arranged in a grid pattern. The energy-absorbing box 21, the vertical and horizontal reinforcement ribs 22, and the horizontal reinforcement ribs 23 are constructed of plastic to ensure that the energy-absorbing element 2 can easily collapse and absorb energy.

[0062] In some embodiments, the energy absorbing member 2 may further include a front side portion 25 and a rear side portion 26. When the energy absorbing member 2 is in the first collision state, the front side portion 25 is first collided and collapses by absorbing energy. When the energy absorbing member 2 is in the second collision state, the energy absorbing member 2 moves toward the device fixing portion 11, the rear side portion 26 contacts the device 10, and the rear side portion 26 collapses by absorbing energy, thereby reducing the probability of the device 10 being damaged by the collision. If the impact force is too large, the rear side portion 26 will knock the device 10 away from the device fixing portion 11 to protect the device 10, so that the device 10 can be recycled again, reducing the high maintenance cost of the device 10. It is worth noting that the strength of the rear side portion 26 is less than the strength of the outer shell of the device 10.

[0063] The energy absorbing member 2 may further include an escape groove 27. The escape groove 27 is located at the rear side portion 26 and extends through the energy absorbing box body 21 in the vertical direction. The escape groove 27 is used to escape the fasteners on the connecting member 1 to prevent the fasteners from interfering with the energy absorbing member 2 during installation.

[0064] like Figures 10 to 13 As shown, the present application also provides a vehicle comprising a crash beam 5, a bumper 6, a device 10, and the device protection apparatus described above. Device 10 is secured to a device securing portion 11, and a connector 1 is secured to the vehicle bottom. Energy absorbers 2 are positioned between device 10 and crash beam 5 in the vehicle's front-to-rear direction.

[0065] The vehicle of the present application is provided with a device protection device. When the vehicle collides, the energy absorbing part 2 can collapse to absorb energy and move to knock down the device 10 to avoid the device 10 being damaged by direct collision with the anti-collision beam 5. At the same time, it also reduces the occurrence of short circuit and fire of the device 10, improves the safety of the passenger compartment, and thus improves the safety performance of the entire vehicle.

[0066] In some embodiments, the energy absorbing box 21 is spaced apart from the device 10 to improve the efficiency of the installation of the energy absorbing member 2 and the device 10 to the connector 1 and prevent interference. During assembly of the device protection device, the energy absorbing member 2 and the device 10 are first installed to the connector 1, and then the connector 1 is installed on the vehicle bottom. This arrangement effectively reduces the number of assembly stations and man-hours.

[0067] To increase the vehicle's storage space, a connector 1 is mounted on the outer bottom surface of the vehicle's storage box. To facilitate the separation of device 10 from device fixing portion 11 in the event of a collision, the side of device fixing portion 11 facing away from energy absorber 2 is no higher than the side adjacent to energy absorber 2 along the vehicle's height. A portion of energy absorber 2 is positioned above device 10, and a guide plate 12 is bent downward from device fixing portion 11.

[0068] Preferably, the connector 1 is tilted, meaning the side of the device fixing portion 11 facing away from the energy absorbing member 2 is lower than the side of the device fixing portion 11 adjacent to the energy absorbing member 2. In the event of a vehicle collision, if the energy absorbing member 2 strikes the device 10, the device 10 can slide toward the ground and fall off, guided by the tilt of the connector 1. This prevents the device 10 from striking other components on the underside of the vehicle, thereby achieving rapid and protected release of the device 10. Furthermore, a guide plate 12 is bent downward from the side of the device fixing portion 11 facing away from the energy absorbing member 2, further guiding the device 10 for rapid release.

[0069] Of course, the connector 1 can also be arranged horizontally, that is, the device fixing portion 11 is arranged parallel to the ground. In the event of a vehicle collision, when the energy absorber 2 strikes the device 10, the device 10 can slide toward the ground and fall off under the guidance of the guide plate 12, thereby preventing the device 10 from striking other components on the bottom of the vehicle. This ensures that the device 10 falls off the device fixing portion 11 and protects the device 10.

[0070] Bumper 6 covers the anti-collision beam 5 and is fixedly connected to the connecting bracket 212. Compared to the original bumper installation method, the connecting bracket 212 provides a mounting point for bumper 6, reducing the development of the original bumper mounting points and saving manufacturing costs. Device 10 can be a high-voltage or low-voltage charging system assembly, a high-voltage or low-voltage converter, an air suspension compressor, and other mechanisms, which will not be detailed here.

[0071] It is worth noting that the bumper 6 can be the front bumper or the rear bumper of the vehicle. Correspondingly, the device protection device can be provided at the front part or the rear part of the vehicle floor, which will not be elaborated herein.

[0072] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
