Description

Technical Field

[0001] This utility model belongs to the field of automotive parts assembly technology, specifically, it relates to an anti-leakage assembly mechanism for automotive headlight components. Background Technology

[0002] The Electronic Control Unit (ECU) is the core electronic control unit in a vehicle, responsible for monitoring, managing, and regulating the operation of various vehicle systems. It's essentially the "brain" of the car, collecting data through sensors, processing information, and controlling actuators. Modern cars typically have multiple ECUs, each managing different subsystems, working together to ensure efficient and safe vehicle operation. Modern intelligent headlights (such as adaptive headlights and matrix LED headlights) are usually controlled by independent ECU submodules, used to adjust the beam angle, brightness, and automatically switch between high and low beams.

[0003] The ECU is externally composed of a rectangular cross-section upper cover and a lower heatsink, which protect the internal integrated components. During assembly, eight rectangular claws at the four corners of the upper cover engage with locking blocks at the four corners of the lower heatsink, thus securing the upper cover and lower heatsink together.

[0004] In practical applications, to maintain airtightness between the upper cover and the lower shell and prevent damage to internal components, a rubber sealing ring needs to be installed at the joint between the upper cover and the lower shell. This is combined with adhesive to further enhance airtightness and achieve high corrosion and moisture resistance. When assembling the upper cover and lower shell, the upper cover needs to be pressed firmly so that the rectangular clips on the upper cover pass over the locking blocks on the lower shell, thus engaging the clips and blocks. The drawback of this method is that the force required during assembly causes the upper cover to compress the sealing ring on the upper part of the lower shell. After the clips and blocks engage, the rings rebound due to elasticity. Therefore, the airtightness of the sealing ring is reduced, and the sealing effect of the encapsulating adhesive is also affected, resulting in the airtightness between the upper cover and the lower shell failing to meet the required performance. Utility Model Content

[0005] To address the technical problem in the prior art where, during the assembly of the upper cover plate and the lower bottom shell, the sealing ring rebounds after being over-pressurized, resulting in a deterioration in the sealing effect of the sealing ring and adhesive, thus affecting the quality of the ECU product, this utility model provides an anti-leakage assembly mechanism for automotive headlight components.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An anti-leakage assembly mechanism for automotive headlight components includes an upper base plate and a lower base shell. Rectangular buckles are fixedly connected to the four sides of the upper base plate. Clamping blocks are fixedly connected to the four sides of the lower base shell. The mechanism also includes a lower base plate disposed directly above the upper base plate. The rectangular buckles are all outwardly folded onto the upper base plate. The upper part of the clamping blocks is inclined. A corresponding hinge block is fixedly connected to the lower base plate at the position of the rectangular buckle. A hinge rod is fixedly connected to the hinge block. A top block is rotatably connected to the hinge rod. The upper part of the top block is connected to a thrust spring, causing its lower part to shift inward. A pressure block is fixedly connected to the lower end of the top block. The outer side of the pressure block is inclined, and the inner side has a protruding structure.

[0008] Furthermore, an upper substrate is disposed above the lower substrate; a floating plate is disposed between the upper substrate and the lower substrate; and guide posts are disposed at the four corners between the upper substrate and the lower substrate.

[0009] Furthermore, the upper and lower ends of the guide post are fixedly connected to the upper substrate and the lower substrate, respectively, and the guide post is slidably connected to the floating plate.

[0010] Furthermore, a return spring is sleeved between the guide post and the lower substrate, so that the floating plate slides on the guide post and moves away from the lower substrate when no force is applied, and the floating plate moves closer to the lower substrate under the push of the cylinder.

[0011] Furthermore, a fixing plate is fixedly installed on the lower surface of the floating plate corresponding to the position of the top block; limit blocks are fixedly connected to both ends of the fixing plate corresponding to the positions of the top block.

[0012] Furthermore, the limiting block is a right-angled triangle, and its inclined surface is arranged facing the inclined surface of the upper part of the top block.

[0013] Furthermore, the latch and the pressure block slide on the inclined surface above the latch under the force applied by the top block, forcing the latch and the pressure block to shift outward.

[0014] Furthermore, the cylinder pushes the floating plate to move downward on the guide post, causing the inclined surface of the limiting block to exert a force on the inclined surface of the top block. The lower part of the top block begins to shift outward, thereby causing the pressure block to shift outward and completely disengage from the locking block.

[0015] Furthermore, the cylinder pushes the upper base plate to move towards the upper bottom plate, so that the floating plate and the lower base plate move towards the upper bottom plate simultaneously, and the pressure block abuts against the inner side of the outwardly folding rectangular buckle provided on the upper bottom plate; the lower base plate moves downward towards the upper bottom plate, and the top block causes the pressure block to shift inward under the action of the thrust spring, and the pressure block continuously applies force to the buckle, and the buckle contacts the buckle.

[0016] Furthermore, the buckle loses the reaction force applied by the inclined surface of the buckle block and loses its abutting state. Under its elastic deformation, the buckle immediately returns to its original position, thereby locking the buckle block onto the buckle and completing the fixation between the upper cover plate and the lower bottom shell.

[0017] The beneficial effects of this utility model are:

[0018] 1. In this utility model, during the engagement process of the buckle and the block, the upper cover plate does not need to actively press down excessively to ensure that the buckle and the block are engaged. It only needs to passively complete the engagement with the block when the buckle passes the lower part of the block, so that the buckle loses its reaction force. This avoids excessive pressing that could damage the sealing ring and glue between the upper cover plate and the lower bottom shell, resulting in reduced air tightness and air leakage, thus improving the quality of the ECU components.

[0019] 2. This utility model uses a cylinder to push a floating plate downward on a guide post, causing the inclined surface of the limiting block to apply a force to the inclined surface of the top block. When the applied force is greater than the force applied by the thrust spring to the top block, the lower part of the top block begins to shift outward, thereby causing the pressure block to shift outward, ensuring that the pressure block is completely disengaged from the locking block, and preventing the ECU component from being lifted when the upper base plate, floating plate and lower base plate are lifted in the future, which would affect subsequent operations.

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.

[0030] Please see Figure 1 - Figure 7 As shown, an anti-leakage assembly mechanism for automotive headlight components includes an upper base plate 1, a lower base plate 3, and a floating plate 2 located between the upper base plate 1 and the lower base plate 3. Guide posts 4 are provided at the four corners between the upper base plate 1 and the lower base plate 3, and the upper and lower ends of the guide posts 4 are fixedly connected to the upper base plate 1 and the lower base plate 3, respectively. The guide posts 4 are slidably connected to the floating plate 2. A return spring 5 is sleeved between the guide posts 4 and the floating plate 2 and the lower base plate 3, which allows the floating plate 2 to slide on the guide posts 4 and move away from the lower base plate 3 when no force is applied. The floating plate 2 moves closer to the lower base plate 3 under the push of a cylinder.

[0031] Please refer to it again. Figures 1-4 As shown, an upper base plate 10 and a lower base shell 12 are arranged sequentially below the lower base plate 3; rectangular buckles 11 with outward turning and symmetrical arrangement are fixed to the four sides of the upper base plate 10; and locking blocks 13 are fixed to the four sides of the lower base shell 12. The upper part of the locking block 13 is inclined. The buckles 11 and the locking blocks 13 cooperate to realize the connection and fixation between the upper base plate 10 and the lower base shell 12.

[0032] Please refer to it again. Figures 5-7 As shown, a hinge block 6 is fixedly connected to the lower base plate 3 at the position corresponding to the rectangular buckle 11; a hinge rod 7 is fixedly connected to the hinge block 6; a top block 8 is rotatably connected to the hinge rod 7, and the upper part of the top block 8 is connected to the thrust spring so that its lower part is offset inward; a pressure block 9 is fixedly connected to the lower end of the top block 8, and the outer side of the pressure block 9 is inclined, and the inner side is a protruding structure.

[0033] Please refer to it again. Figure 7 As shown, a fixing plate 14 is fixedly installed on the lower surface of the floating plate 2 at the position corresponding to the top block 8; limiting blocks 15 are fixedly connected to both ends of the fixing plate 14 at the positions corresponding to the top block 8. The limiting blocks 15 are right-angled triangles, and their inclined surfaces are facing the inclined surfaces of the upper part of the top block 8.

[0034] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0035] S1: Place the upper base plate 10 naturally on the lower base shell 12, and then use the cylinder to push the upper base plate 1 to move to the upper base plate 10, so that the floating plate 2 and the lower base plate 3 move closer to the upper base plate 10 at the same time, until the pressure block 9 abuts against the inside of the outwardly folding rectangular buckle 11 provided on the upper base plate 10.

[0036] S2: Continue to move downwards through the lower base plate 3 and approach the upper base plate 10. At this time, because the top block 8 causes the pressure block 9 to shift inwards under the action of the thrust spring, the pressure block 9 will continue to apply force to the buckle 11 until the buckle 11 contacts the buckle block 13.

[0037] S3: Under the force applied by the top block 8, the buckle 11 and the pressure block 9 slide on the inclined surface of the upper part of the buckle block 13. Therefore, the buckle 11 has a rib-like structure with elastic deformation capability, which forces the buckle 11 and the pressure block 9 to shift outward until the buckle 11 slides to the bottom of the buckle block 13.

[0038] S4: Because the buckle 11 loses the reaction force applied by the inclined surface of the buckle block 13, it loses the abutting state. Therefore, the buckle 11 immediately returns to its original position under its elastic deformation, thereby locking the buckle block 13 onto the buckle 11 and completing the fixation between the upper cover plate and the lower bottom shell 12.

[0039] In this design, during the engagement of the latch 11 and the latch block 13, the upper cover does not need to actively press down excessively to ensure that the latch 11 and the latch block 13 are engaged. Instead, the latch 11 only needs to pass the lower part of the latch block 13 so that it loses its reaction force and passively engages with the latch block 13. This avoids excessive pressing that could damage the sealing ring and adhesive between the upper cover and the lower bottom shell 12, leading to reduced air tightness and air leakage, thus improving the quality of the ECU components.

[0040] In step S3, in order to ensure that the pressure block 9 is completely detached from the card block 13 and to prevent the ECU assembly (specifically referring to the upper cover plate, lower bottom shell 12 and internally integrated electronic components) from being lifted when the upper base plate 1, floating plate 2 and lower base plate 3 are lifted in the future, thus affecting subsequent operations, the following steps are also performed.

[0041] S5: The floating plate 2 is pushed down on the guide post 4 by the cylinder, so that the inclined surface of the limiting block 15 applies a force to the inclined surface of the top block 8. When the applied force is greater than the force applied to the top block 8 by the thrust spring, the lower part of the top block 8 begins to shift outward, which in turn causes the pressure block 9 to shift outward, ensuring that the pressure block 9 is completely disengaged from the locking block 13.

[0042] S6: Move the upper base plate 1, floating plate 2 and lower base plate 3 upward as a whole, so that they are far away from the upper cover plate and lower bottom shell 12 of the ECU.

[0043] S7: Stop applying force to the floating plate 2 through the cylinder, so that the floating plate 2 moves upward under the action of the return spring 5, thereby restoring the top block 8 to its original vertical state.

[0044] S8: After the ECU under the lower substrate 3 is moved away, continue to assemble other ECU components.
