Description

Technical Field

[0001] This utility model relates to the field of power supply box housing technology, and more specifically, to an automotive anti-collision power supply box housing. Background Technology

[0002] The automotive power distribution box, also known as the fuse box, houses various relays and safety devices. To facilitate troubleshooting during assembly and maintenance, modern cars typically integrate these relays and safety devices into a single distribution box, also called a central distribution box.

[0003] For example, the patent with publication number CN212062362U discloses a waterproof fuse box for automobiles. While this type of waterproof fuse box is beneficial for the vehicle to operate normally in harsh environments, ensuring driving safety, and is more convenient to install and remove than other waterproof boxes of the same level, saving time and effort, in actual use, the fuse box cover is installed on the fuse box base through an interference fit between the fastener and the wedge-shaped base. This means that the cover only serves to seal the fuse box base, resulting in the lack of impact protection when the fuse box is subjected to impact. Consequently, the relays inside the fuse box are easily damaged by the impact, and therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive anti-collision power supply box housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0029] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0030] Combination Figures 1-6As shown, an automotive anti-collision power supply box housing in this embodiment includes a box body 200, a cavity 201 with an upper opening inside the box body 200, and a cover 100 at the opening of the cavity 201; the cover 100 extends downward around its perimeter to form an anti-collision part 103 that fits against the box body 200, and an energy-absorbing cavity 501 is provided inside the anti-collision part 103; a fixing plate 202 is provided on the opposite side wall at the opening of the cavity 201; a chamber 500 is provided inside the cover 100 at its upper end, and slots 400 for inserting corresponding fixing plates 202 into the chamber 500 are provided on the bottom wall of the chamber 500; a positioning hole 203 is provided on the fixing plate 202, and a locking component is provided inside the chamber 500. The locking component is inserted into the corresponding positioning hole 203 to fix the cover 100 on the box body 200; a mounting component for installing a relay is provided inside the cavity 201.

[0031] In practical use, the enclosure 200 is bolted to the anti-collision beam of the car, allowing the power supply box housing to be installed on the vehicle. The mounting components allow the relay to be installed inside the cavity 201. Specifically, a wiring hole 301 communicating with the cavity 201 is provided on the side wall of the enclosure 200 at its lower end. A notch 401 aligned with the wiring hole 301 is provided on the side wall of the cover 100. The wiring hole 301 allows the vehicle's wiring to be connected to the relay located inside the cavity 500. The notch 401 allows the wiring to be opened without disconnecting the wiring, facilitating practical use.

[0032] In actual use, the cover 100 is adapted to the box body 200, so that the box body 200 can be completely covered inside the box body 200. At the same time, the side wall of the box body 200 can slide against the corresponding side wall of the cover 100, so that the cover 100 will not shake on the box body 200, thus allowing the cover 100 to be better fixed on the box body 200.

[0033] In this way, by fastening the cover 100 onto the housing 200, the fixing plate 202 can be inserted into the chamber 500 through the slot 400. By setting the locking component, the locking component is inserted into the corresponding positioning hole 203, so that the cover 100 can be fixedly installed on the housing 200, thereby better protecting the relay in the chamber 201.

[0034] The energy-absorbing cavity 501 is designed so that when a vehicle collides and impacts the cover 100, the anti-collision part 103 can deform through the energy-absorbing cavity 501, thereby better absorbing the energy brought by the impact and thus better protecting the relays inside the housing 200.

[0035] Specifically, multiple reinforcing ribs 102 are evenly provided on the outer side wall of the anti-collision part 103. By setting the reinforcing ribs, the strength of the anti-collision part 103 can be increased, thereby improving the anti-collision effect of the box cover 100.

[0036] Combination Figures 5-6 As shown, in this embodiment, a T-shaped groove 503 is provided on the bottom wall of the chamber 500 along the width direction of the cover 100; the locking assembly includes a slider 504 that is disposed opposite to and slidable within the groove 503, and a locking rod 507 that can be inserted into the corresponding positioning hole 203 at one end of the slider 504; an abutment plate 506 is also provided inside the chamber 500, and the locking rod 507 is disposed through the abutment plate 506. A first spring 508 for pushing the slider 504 to reset is sleeved on the locking rod 507 located between the abutment plate 506 and the slider 504; the locking assembly also includes a driving member, which is used to drive the slider 504 to drive the locking rod 507 to insert into the corresponding positioning hole 203.

[0037] In actual use, the slider 504 is driven by the driving component to slide along the slide groove 503, so that the slider 504 can drive the locking rod 507 to move and compress the first spring 508, so that the locking rod 507 can be inserted into the positioning hole 203 on the corresponding fixing plate 202, thereby allowing the box cover 100 to be fixedly installed on the box body 200. At the same time, when the driving component cancels the driving of the slider 504, the first spring 508 can push the slider 504 to reset under the action of the first spring 508, so that the locking rod 507 can disengage from the corresponding positioning hole 203, thereby releasing the box cover 100 from the box body 200.

[0038] In actual use, to prevent the first spring 508 from causing the locking rod 507 to disengage from the abutment plate 506 when pushing the slider 504 to reset, thus affecting the next use, a first limiting groove 601 is provided on the outer wall of the locking rod 507 along its axial direction, and a first limiting block 602 is provided on the abutment plate 506 for sliding into the first limiting groove 601. With the setting of the first limiting groove 601 and the first limiting block 602, when the first spring 508 pushes the slider 504 to reset the locking rod 507, the first limiting block 602 can slide in the first limiting groove 601. When the first limiting block 602 slides to abut against the corresponding side wall of the first limiting groove 601, the first spring 508 stops pushing the slider 504 to reset. At this time, the locking rod 507 will not disengage from the abutment plate 506, so that the locking rod 507 can always be aligned with the corresponding positioning hole 203, without affecting the next use.

[0039] The slide groove 503 is adapted to the slider 504, so that the slider 504 can be slidably installed in the chamber 500;

[0040] Combination Figures 5-6As shown, in this embodiment, a first inclined surface is provided at the other end of the slider 504; the driving member includes a driving block 505, and a second inclined surface adapted to the first inclined surface is provided on the opposite side wall of the driving block 505. A driving rod extending out of the chamber 500 is vertically provided on the upper side wall of the driving block 505. A second spring 502 is provided on the driving rod located between the driving block 505 and the upper side wall of the chamber 500. The second spring 502 is used to push the driving block 505 down.

[0041] In actual use, in the initial state, the second spring 502 pushes the drive block 505 downward, so that the second inclined surface can fit against the first inclined surface. At this time, the second spring 502 continues to push the drive block 505 downward, so that the second inclined surface can slide and press the first inclined surface, so that the first inclined surface can drive the slider 504 to move along the slide groove 503 and drive the locking rod 507 to move, and compress the first spring 508, so that the locking rod 507 can be inserted into the corresponding positioning hole 203, so that the box cover 100 can be fixedly installed on the box body 200. When the drive rod is lifted, the drive rod can drive the drive block 505 upward and compress the second spring 502, so that the second inclined surface can disengage from the first inclined surface, and then the slider 504 is reset under the action of the first spring 508. At this time, the locking rod 507 disengages from the positioning hole 203, thereby releasing the box cover 100 from the box body 200.

[0042] In actual use, in order to ensure that the second inclined plane can be aligned with the first inclined plane, in this embodiment, a second limiting groove 600 is provided on the drive rod along its axial direction, and a second limiting block is provided on the upper side wall of the chamber 500, which slides into the second limiting groove 600; by setting the second limiting groove 600 and the second limiting block, the drive rod will not rotate, so that the second inclined plane can always be aligned with the first inclined plane;

[0043] The second spring 502 is designed such that its upper end abuts against the upper side wall of the chamber 500 and its lower end abuts against the upper side wall of the drive block 505. This allows the second spring 502 to continuously push the drive block 505 downward, thereby ensuring that the drive block 505 remains in the state where the drive slider 504 drives the locking rod 507 to insert into the positioning hole 203. This ensures that the cover 100 remains fixed on the box body 200.

[0044] In this embodiment, to facilitate the operator in lifting the drive rod, a pull post 101 is provided at the end of the extended end of the drive rod. The pull post 101 facilitates the operator in lifting the drive rod.

[0045] Combination Figure 3As shown, in this embodiment, the mounting assembly includes mounting plates 204 disposed on opposite sidewalls of the cavity 201. Multiple U-shaped mounting brackets 205 are provided between the opposite mounting plates 204 along the length of the housing 200. Multiple threaded holes for mounting relays are provided on the mounting brackets 205.

[0046] In actual use, the mounting plate 204 is fixedly mounted on the corresponding side wall of the cavity 201 by screws, and the mounting bracket 205 is fixedly mounted between the opposite mounting plates 204 by screws, so that the mounting bracket 205 can be installed in the cavity 201. Through the setting of the threaded hole, the relay can be fixedly mounted on the mounting bracket 205 by screws, so that the relay can be installed on the mounting bracket 205, thereby allowing the relay to be installed in the cavity 201.

[0047] Multiple ventilation holes 300 are evenly distributed on the side wall of the housing 200 and the corresponding side wall of the cover 100. The ventilation holes 300 allow the air inside the cavity 201 to be ventilated and cooled.

[0048] In practical use, the housing 200 is first fixed to the car's anti-collision beam with screws. Next, the relay is installed on the mounting bracket 205. Then, the lifting column 101 is raised, causing the drive rod to move the drive block 505 upwards and compress the second spring 502, allowing the second inclined surface to disengage from the first inclined surface. This allows the first spring 508 to drive the slider 504 to reset. Finally, the housing cover 100 is placed over the housing 200, allowing the fixing plate 202 to pass through the corresponding slot 400 and insert into the chamber 50. At this point, the pull column 101 is released, causing the second spring 502 to push the drive block 505 down, so that the second inclined surface can fit against the first inclined surface. At this time, the second spring 502 continues to push the drive block 505 down, so that the second inclined surface can slide and squeeze the first inclined surface, so that the first inclined surface can drive the slider 504 to move along the slide groove 503 and drive the locking rod 507 to move, and compress the first spring 508, so that the locking rod 507 can be inserted into the corresponding positioning hole 203, so that the box cover 100 can be fixedly installed on the box body 200.

[0049] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
