Description

Technical Field

[0001] This utility model relates to the field of controller housing technology, specifically to a protective housing for an automotive controller. Background Technology

[0002] With the increasing use of automobiles, cars provide us with a comfortable driving environment. The simple and quick operation of the car while driving also provides great convenience. The car controller is a master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0003] Chinese patent CN221081716U discloses a controller housing and an automobile controller. The upper housing and the integrated fixing frame and the lower housing are all independent components, which can be manufactured with only one mold, saving the mold opening cost. The setting of the fixing frame makes it convenient and flexible to install the housing in the designated position. At the same time, the bolt connection ensures the stability of the connection between the upper housing and the lower housing.

[0004] The above solution uses bolts to connect and fix the split upper and lower shells. Although bolts can achieve a stable connection between the two shells, multiple bolts need to be disassembled sequentially during subsequent maintenance, which takes a long time. Furthermore, after repeated installation, the bolts are prone to loosening due to wear of the bolt holes, affecting the stability of the shells.

[0005] Therefore, this utility model provides a protective housing for an automotive controller to solve the above-mentioned problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the prior art, this utility model provides a protective housing for an automotive controller to solve the problem that the housing is connected by bolts, which requires the sequential disassembly of multiple bolts during subsequent maintenance, taking a long time to disassemble and assemble. Furthermore, after repeated installation, the bolts are prone to loosening due to wear of the bolt holes, affecting the stability of the housing.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A protective housing for an automotive controller includes a base plate and an upper housing. A lower housing is fixedly connected to the base plate. The upper housing has a receiving cavity and is inserted into the lower housing through the receiving cavity. A limiting hole is provided on the lower housing.

[0009] A rotating rod is rotatably connected to the upper housing, and a rotating plate is fixedly connected to the rotating rod. Both ends of the rotating plate are hinged to hinge rods, and a linkage plate is hinged to the end of the hinge rod away from the rotating plate. A limit rod is fixedly connected to the linkage plate, and the connection between the lower housing and the upper housing is completed by inserting the limit rod into the limit hole. A guide seat is fixedly connected to the upper housing, and the limit rod is slidably connected to the guide seat.

[0010] Preferably, a fixing ring is fixedly connected to the limiting rod, and a first spring is sleeved on the limiting rod, with the two ends of the first spring abutting against the fixing ring and the guide seat, respectively.

[0011] Preferably, the lower housing has cable inlet / outlet ports and heat dissipation holes, and the base plate has mounting holes.

[0012] Preferably, a screw block is fixedly connected to the end of the rotating rod away from the rotating plate, and the screw block is located above the upper housing.

[0013] Preferably, an installation ring is fixedly connected to the upper housing, and a shielding dish is threadedly connected to the installation ring, with the screw block located inside the shielding dish.

[0014] Preferably, a limiting groove is provided on the screw block, a storage tube is fixedly connected to the upper housing, a positioning rod is slidably connected to the storage tube, and one end of the positioning rod is inserted into the limiting groove.

[0015] Preferably, a slider is slidably connected inside the storage tube, one end of the positioning rod is fixedly connected to the slider, and a second spring is provided inside the storage tube, with the two ends of the second spring abutting against the slider and the upper shell respectively.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By coordinating the rotating rod, rotating plate, hinge rod, linkage plate, limiting hole, and limiting rod, the rotating rod drives the rotating plate to rotate, which in turn causes the hinge rod to move the linkage plate. This allows for synchronous control of the two sets of limiting rods, thus enabling the limiting rods to move within the limiting hole. The housing can be quickly disassembled and assembled by simply rotating a single screw block, avoiding the tedious process of disassembling multiple bolts sequentially in traditional methods. This significantly shortens the disassembly and assembly time and improves maintenance efficiency.

[0018] 2. By setting the first spring to support the fixing ring, the limiting rod can be firmly inserted into the limiting hole, which increases the stability of the connection between the upper and lower shells. By connecting the shielding dish to the upper shell with the mounting ring, additional protection is provided, which not only avoids damage to the rotating mechanism from external collisions, but also prevents unauthorized personnel from operating it by mistake. The design of the positioning rod and the storage tube can lock the screw block when not in operation, further preventing accidental contact or unnecessary rotation, thus improving the safety and reliability of the overall structure.

[0025] The following will refer to the attached reference. Figures 1 to 5 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0026] A protective housing for an automotive controller, such as Figures 1 to 5 As shown, the device includes a base plate 1 and an upper housing 3. A lower housing 2 is fixedly connected to the base plate 1. The lower housing 2 has inlet / outlet ports and heat dissipation holes. The controller chip needs to be installed inside the lower housing 2. The inlet / outlet ports are used to connect the chip to external electrical components and to supply power to the chip. The heat dissipation holes ensure that the air inside the lower housing 2 can be exchanged with the outside air, thereby ensuring heat dissipation for the chip. The base plate 1 has mounting holes, which facilitate the fixing of the base plate 1 inside the vehicle body. The upper housing 3 has a receiving cavity 4, and the upper housing 3 is inserted into the lower housing 2 through the receiving cavity 4. The upper housing 3 is inserted into the top of the lower housing 2 in a covering manner through the receiving cavity 4. The lower housing 2 has a limiting hole 21.

[0027] The upper housing 3 is rotatably connected to a rotating rod 5, and a rotating plate 6 is fixedly connected to the rotating rod 5. Both ends of the rotating plate 6 are hinged to hinge rods 7, and the end of the hinge rod 7 away from the rotating plate 6 is hinged to a linkage plate 8. By rotating the rotating rod 5, the rotating plate 6 can move closer to and further away from the two linkage plates 8 through the hinge rods 7. A limit rod 10 is fixedly connected to the linkage plate 8, and the lower housing 2 and the upper housing 3 are connected by inserting the limit rod 10 into the limit hole 21. When the linkage plate 8 moves, it can perform two actions: inserting the limit rod 10 into the limit hole 21 and pulling the limit rod 10 out of the limit hole 21. This can achieve the limiting and releasing of the lower housing 2 and the upper housing 3. A guide seat 9 is fixedly connected to the upper housing 3, and the limit rod 10 is slidably connected to the guide seat 9. The guide seat 9 guides the movement of the limit rod 10.

[0028] In this embodiment, a fixing ring 11 is fixedly connected to the limiting rod 10, and a first spring 12 is sleeved on the limiting rod 10. The two ends of the first spring 12 abut against the fixing ring 11 and the guide seat 9, respectively. The elasticity of the first spring 12 itself supports the fixing ring 11, which can ensure the stability of the limiting rod 10 when inserted into the limiting hole 21.

[0029] A screw block 13 is fixedly connected to the end of the rotating rod 5 away from the rotating plate 6, and the screw block 13 is located above the upper housing 3. The rotating rod 5 can be easily rotated and adjusted by the screw block 13.

[0030] The upper housing 3 is fixedly connected to an installation ring 14, and a shielding dish 15 is threadedly connected to the installation ring 14. The screw block 13 is located inside the shielding dish 15. The shielding dish 15 is installed on the installation ring 14 to shield the screw block 13 and prevent the screw block 13 from being damaged due to collision inside the vehicle body.

[0031] In this embodiment, a limiting groove 16 is provided on the screw block 13, and a storage tube 17 is fixedly connected to the upper housing 3. A positioning rod 20 is slidably connected to the storage tube 17. One end of the positioning rod 20 is inserted into the limiting groove 16. The screw block 13 is rotated and limited by inserting the positioning rod 20 into the limiting groove 16.

[0032] A slider 18 is slidably connected inside the storage tube 17. One end of the positioning rod 20 is fixedly connected to the slider 18. A second spring 19 is provided inside the storage tube 17. The two ends of the second spring 19 abut against the slider 18 and the upper housing 3, respectively. When it is necessary to rotate and adjust the screw block 13, the positioning rod 20 needs to be pushed out from the limiting groove 16, that is, the positioning rod 20 is stored in the storage tube 17. At this time, the positioning rod 20 will drive the slider 18 to move in the storage tube 17, thereby squeezing the second spring 19. The second spring 19 in the squeezed state will quickly reset when the positioning rod 20 needs to be inserted into the limiting groove 16.
