Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to an automotive relay and its mounting bracket. Background Technology

[0002] Automotive relays may vibrate during operation, especially when switching on and off high currents. The bracket needs to provide sufficient mechanical strength and fixing force to prevent the relay from loosening, falling off, or making poor contact. The snap-fit ​​design or specific screw fixing is to enhance stability.

[0003] A search revealed a car relay mounting structure disclosed in patent application publication number CN106252159B, comprising: a relay housing and a relay mounting bracket; the relay mounting bracket includes: a support part, a limiting and fixing part, and a force-adjusting part; the support part has a U-shaped structure, and the limiting and fixing parts are symmetrically arranged at both ends of the support part; when disassembling the car relay, the force-adjusting part is pressed inward to separate the limiting and fixing part from the car sheet metal.

[0004] The aforementioned patent replaces the traditional screw sheet metal fixing with a U-shaped buckle. Although this can solve the problem of inconvenient disassembly of automotive relays in enclosed spaces, the U-shaped buckle is fixed to the top of the relay. When the U-shaped buckle is inserted into the mounting hole of the sheet metal, if the position of the terminal connector at the bottom of the relay does not match the automotive part to be connected, and the direction of the U-shaped buckle cannot be changed, it may not only affect the installation effect, but also affect the stability of the circuit connection. Utility Model Content

[0005] The purpose of this utility model is to provide an automotive relay and mounting bracket that can adjust the direction of the latch and make the installation more stable, so as to solve the problem mentioned in the background art where the external latch structure of the automotive relay is directly fixed to the relay housing. When the position of the bottom terminal connector of the relay is not compatible with the automotive part to be connected, and the direction of the U-shaped latch cannot be changed, the installation effect is affected.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mounting bracket, comprising an inner shell and an outer shell fixed with buckles, wherein the outer wall of the outer shell is further provided with two sets of arc-shaped buckles that can form a three-point fixation with the buckles; a rotating structure capable of adjusting the angle of the outer shell is provided between the top of the outer wall of the inner shell and the top of the inner cavity of the outer shell; and a positioning structure capable of positioning the adjusted outer shell is provided on the outer wall of the outer shell.

[0007] The positioning structure includes a pressing rod that passes through the outer shell and is slidably connected to the outer shell. The top of the outer shell is provided with a locking structure that locks the pressing rod after it is pressed.

[0008] Preferably, the snap-fit ​​structure includes a slot for inserting a pressing rod, the slot being located at the top of the inner shell, and a locking groove being provided on the inner wall of the slot. The locking groove is configured in two sets, upper and lower, with a sliding groove between the two sets of locking grooves, the sliding groove being located on the inner wall of the slot.

[0009] Preferably, the snap-fit ​​structure further includes a locking ring integrally formed on the outer wall of the pressing rod, the locking ring being snapped into the slot.

[0010] Preferably, the top of the pressing rod has an opening that facilitates lifting the pressing rod, the opening penetrates the outer wall of the pressing rod, and the end of the arc-shaped buckle away from the outer shell is provided with an integrally formed clip.

[0011] Preferably, the rotating structure includes a fixing rod integrally formed on the top of the inner cavity of the outer shell, and the top of the inner shell has a slot for inserting the fixing rod. The slot is fitted with a bearing, the outer ring of the bearing is fixedly connected to the inner wall of the slot, and the inner wall of the bearing inner ring is fixedly connected to the outer wall of the boss.

[0012] Preferably, the buckle is U-shaped, and both ends of the U-shaped end of the buckle are provided with extended edges for the sheet metal mounting groove to be inserted. The extended edges are U-shaped, and one end of the extended edge is provided with an integrally formed arc edge, one end of which is fused to the outer wall of the shell.

[0013] An automotive relay, installed in a mounting bracket as described above, includes a relay body, which is fixed to an inner housing by screws. The bottom end of the inner housing is open, and a terminal is fixed to the bottom end of the relay body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a rotating structure, allows the outer shell, which is fixed with the buckle and the arc-shaped buckle, to rotate 360° relative to the inner shell that fixes the relay body. When the position of the terminal connector at the bottom of the relay does not match the direction of the automotive component to be connected, such as the wiring harness socket, there is no need to change the position of the relay body in the inner shell or forcibly twist the wiring harness. Simply rotating the outer shell can adjust the direction of the buckle and the arc-shaped buckle, making them precisely aligned with the mounting holes on the vehicle body sheet metal, thus improving the compatibility of installation.

[0016] 2. The three-point fastening system, combining the two curved clips on both sides, works together to secure the relay to the vehicle body sheet metal. Compared to a single U-shaped clip or traditional screw fixing, this three-point fixing provides a more stable relay installation. It is especially suitable for relays with high current switching capabilities, reducing the risk of relay loosening, falling off, or poor contact, and ensuring long-term reliability of the electrical connection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an installation bracket, including an inner shell 1 and an outer shell 3 with a buckle 2 fixed thereon. The outer wall of the outer shell 3 is also provided with two sets of arc-shaped buckles 4 that can form a three-point fixation with the buckle 2. A rotating structure 5 that can adjust the angle of the outer shell 3 is provided between the top of the outer wall of the inner shell 1 and the top of the inner cavity of the outer shell 3. The outer wall of the outer shell 3 is provided with a positioning structure 6 that can position the adjusted outer shell 3.

[0024] The positioning structure 6 includes a pressing rod 601, which penetrates the outer shell 3 and is slidably connected to the outer shell 3. The top of the outer shell 3 is provided with a locking structure 602 that locks the pressing rod 601 after it is pressed.

[0025] By setting the arc-shaped buckle 4, the relay body 7 installed in the inner shell 1 can be positioned at three points by the main top fastening and the auxiliary side fastening, which can improve the installation stability of the relay body 7.

[0026] The snap-fit ​​structure 602 includes a snap-fit ​​groove 6021 for inserting a pressing rod 601. The snap-fit ​​groove 6021 is located on the top of the inner shell 1. The inner wall of the snap-fit ​​groove 6021 is provided with a locking groove 6022. The locking groove 6022 is configured in two sets, upper and lower. A sliding groove 6023 is provided between the two sets of locking grooves 6022. The sliding groove 6023 is located on the inner wall of the snap-fit ​​groove 6021.

[0027] The snap-fit ​​structure 602 also includes a locking ring 6024 integrally formed on the outer wall of the pressing rod 601, which is snapped into the slot 6021.

[0028] The pressing rod 601 can slide up and down along the outer shell 3. Initially, the locking ring 6024 at the bottom of the pressing rod 601 engages with the locking groove 6022 at the top of the inner shell 1. The outer shell 3 can be manually rotated to adjust the angle. When locked: Pressing down the pressing rod 601 causes the locking ring 6024 to disengage from the upper locking groove 6022 and enter the lower locking groove 6022. At this time, the bottom end of the pressing rod 601 presses against the top of the inner shell 1, increasing the friction with the inner shell 1, thus braking the outer shell 3 and preventing it from rotating, completing the locking process. Figure 4 As shown.

[0029] When unlocking: Pull up the pressing rod 601 to make the locking ring 6024 enter the upper sliding groove. At this time, the bottom end of the pressing rod 601 is separated from the inner shell 1 and does not contact the inner shell 1, so that the outer shell 3 can rotate.

[0030] The top of the pressing rod 601 has an opening 6025 to facilitate lifting the pressing rod 601. The opening 6025 penetrates the outer wall of the pressing rod 601. The arc-shaped buckle 4 has an integrally formed clip 6026 at the end away from the outer shell 3.

[0031] By providing opening 6025, when it is difficult to apply force to the upward pressing rod 601, the rope can be inserted through opening 6025 to perform the upward pulling operation. The structure of the clamp 6026 is as follows: Figure 2 As shown, it is a horizontally placed frustum with a slot on the side wall, which allows it to deform and be inserted into the mounting hole of the sheet metal. The large-diameter end of the clip 6026 is pressed against the back of the sheet metal plate to achieve locking.

[0032] The rotating structure 5 includes a fixing rod 501 integrally formed on the top of the inner cavity of the outer shell 3. The top of the inner shell 1 has a slot 503 for inserting the fixing rod 501. A bearing 504 is installed in the slot 503. The outer ring of the bearing 504 is fixedly connected to the inner wall of the slot 503, and the inner wall of the inner ring of the bearing 504 is fixedly connected to the outer wall of the boss.

[0033] When the outer casing 3 is rotated, the inner and outer rings of the bearing 504 rotate relative to each other, causing the outer casing 3 to freely adjust the direction of the buckle 2 and the arc buckle 4, while the inner casing 1 and the fixed relay body 7 remain stationary to adapt to the direction of the wiring harness socket and avoid forcibly twisting the circuit.

[0034] The buckle 2 is U-shaped, and both ends of the U-shaped end of the buckle 2 are provided with an extension edge 201 for the sheet metal mounting groove to be inserted. The extension edge 201 is U-shaped, and one end of the extension edge 201 is provided with an integrally formed arc edge 202. One end of the arc edge 202 is fused to the outer wall of the outer shell 3.

[0035] The clip 2 structure is the same as the clip 2 structure in the automotive relay mounting structure disclosed in patent application publication number CN106252159B, and serves as the main positioning point of the relay body 7.

[0036] An automotive relay, mounted in a mounting bracket as described above, includes a relay body 7, which is fixed to an inner housing 1 by screws. The bottom end of the inner housing 1 is open, and a terminal 8 is fixed to the bottom end of the relay body 7. The terminal 8 at the bottom of the relay body 7 is used to connect to an automotive wiring harness socket.

[0037] When using, first adjust the angle of the relay body 7 according to the direction of the car wiring harness socket. Specifically: Initial state: Press the locking ring 6024 at the bottom of the lever 601 into the locking groove 6022 at the top of the inner shell 1, and manually rotate the outer shell 3 to adjust the angle.

[0038] Locking after adjustment: Press down the pressing rod 601 to disengage the locking ring 6024 from the upper locking groove 6022 and into the lower locking groove 6022. At this time, the bottom end of the pressing rod 601 presses against the top of the inner shell 1, increasing the friction with the inner shell 1, thus braking the outer shell 3 and preventing it from rotating, completing the locking process. Figure 4 As shown;

[0039] Align the buckle 2 and the two arc-shaped buckles 4 with the mounting slots on the sheet metal plate, and apply a force toward the sheet metal plate to the outer shell 3, inner shell 1 and relay body 7 as a whole, so that the buckle 2 and the clip head 6026 are snapped into the sheet metal plate to achieve installation.

[0040] Compared to the traditional clip-on mounting, this automotive relay and mounting bracket can achieve three-point mounting, improving installation stability. At the same time, the position of clip-on 2 is adjustable to adapt to the wiring harness socket in the car.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
