[0002] The vehicle controller mainly includes functions such as vehicle power-on / off, control mode judgment and driving control, vehicle network management, brake energy feedback control, vehicle energy management and optimization, fault diagnosis and handling, and vehicle status monitoring and display. The circuit board mounting structure of the vehicle controller usually needs to have good mechanical stability to cope with mechanical stresses such as vibration and impact generated during vehicle operation.

[0003] Currently, the circuit boards of vehicle controllers (such as vehicle controllers, motor controllers, etc.) are generally fixed with standard fasteners. Specifically, the circuit board is rigidly connected to the housing of the vehicle controller by multiple screws to achieve stable fixation.

[0004] However, disassembly requires loosening each screw individually, which is tedious and time-consuming. Especially when the controller is highly integrated, the internal installation space is narrow and tool operation is limited, increasing the difficulty of disassembly. Moreover, frequent disassembly and assembly can easily lead to stripped screws or damaged threaded holes, affecting the reliability of the fixation. Utility Model Content

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Please refer to Figures 1 to 5This invention provides a quick-release circuit board structure applied to the housing 100 of a vehicle controller. The quick-release structure includes a protruding post 200, a mounting post 300, and a U-shaped elastic element 400. The protruding post 200 is disposed on the housing 100, and has a positioning groove 210 in its middle. The outer wall of the positioning groove 210 has opposing clamping grooves 211 that penetrate the side wall of the positioning groove 210 and communicate with the central hollow area of ​​the positioning groove 210. The upper end of the mounting post 300 is used to connect the circuit board, and the lower end of the mounting post 300 is inserted into the positioning groove 210. The elastic straight arms 410 on both sides of the U-shaped elastic element 400 are respectively embedded in the two clamping grooves 211, and the elastic curved arm 420 in the middle of the U-shaped elastic element 400 is detachably disposed on the housing 100.

[0031] When assembling the circuit board, firstly, the elastic curved arm 420 in the middle of the U-shaped elastic element 400 is assembled onto the housing 100. Then, the elastic straight arms 410 on both sides of the U-shaped elastic element 400 are inserted into the clamping groove 211. At this time, the elastic straight arms 410 expand and deform outward along the axial direction of the positioning groove 210. The elastic force generated by the expansion and deformation of the elastic straight arms 410 makes the elastic straight arms 410 tightly clamp the inner wall of the clamping groove 211, thereby preventing the elastic straight arms 410 from loosening. Then, the lower end of the mounting post 300 is inserted into the positioning groove 210. At this time, the positioning groove 210 presses the elastic straight arms 410 on both sides of the U-shaped elastic element 400 radially outward, so that the elastic straight arms 410 on both sides further expand and deform outward along the axial direction of the positioning groove 210. The elastic force generated by the expansion and deformation of the elastic straight arms 410 makes the elastic straight arms 410 tightly clamp the outer wall of the mounting post 300, but the elastic straight arms 410 are always limited within the clamping groove 211. When you need to remove the circuit board, simply pull it outwards.

[0032] To increase the friction between the mounting post 300 and the elastic straight arm 410, and to increase the friction between the outer wall of the mounting post 300 and the inner wall of the positioning groove 210, in some optional embodiments, the mounting post 300 is an elastic structure. When the elastic straight arm 410 presses the outer wall of the mounting post 300 axially inward, the mounting post 300 will undergo radial deformation. The deformed mounting post 300 presses the inner wall of the positioning groove 210. At the same time, the contact point between the radially deformed mounting post 300 and the elastic straight arm 410 is no longer a point contact, but a larger area of ​​surface contact, thereby increasing the friction.

[0033] In some alternative embodiments, to maintain a stable clamping state between the resilient straight arm 410 and the mounting post 300, such as Figure 2 , Figure 3 , Figure 5As shown, a limiting groove 212 is provided on the inner side wall of the positioning groove 210, and a protrusion 310 is provided on the mounting column 300. After the limiting groove 212 and the protrusion 310 are engaged, the mounting column 300 inserted in the positioning groove 210 cannot rotate axially.

[0034] In some alternative embodiments, to facilitate the replacement of a failed U-shaped elastic element 400, the elastic arm 420 in the middle of the U-shaped elastic element 400 is detachably mounted on the housing 100. Figure 2 , Figure 3 As shown, the housing 100 is provided with an elastic arm 110. The elastic arm 110 and the outer wall of the protrusion 200 form a slot 500 for engaging the elastic curved arm 420. During assembly, the elastic curved arm 420 is pressed into the slot 500 from the opening of the slot 500. When removing it, the elastic curved arm 420 is pulled outward with force.

[0035] In some alternative embodiments, such as Figure 1 , Figure 4 As shown, the housing 100 also includes a cover 600, which is detachably disposed on the housing 100. The cover 600 and the housing 100 cooperate to form a closable accommodating cavity, which is used to accommodate the circuit board. The quick-release structure of the circuit board is disposed in the accommodating cavity.

[0036] In some optional embodiments, to further reduce the probability of the elastic crank arm 420 popping out of the slot 500, an elastic sleeve (not shown in the figures) is provided inside the slot 500 to wrap the elastic crank arm 420. The elastic sleeve has protrusions (not shown in the figures) distributed on it, and the side wall of the slot 500 has concave points (not shown in the figures) that mate with the protrusions. By providing the elastic sleeve and the mate between the protrusions and concave points, the friction between the elastic crank arm 420 and the inner wall of the slot 500 can be increased, and the impact of vibrations and impacts generated during vehicle operation on the clamping relationship between the slot 500 and the elastic crank arm 420 can be reduced.

[0037] In some alternative embodiments, such as Figure 1 , Figure 4 As shown, the housing 100 is provided with a guide block 120, and the cover 600 is provided with a guide groove 610 that cooperates with the guide block 120. The length of the guide groove 610 is greater than the length of the guide block 120. When assembling the cover 600, the guide block 120 is inserted into the guide groove 610. Since the length of the guide groove 610 is greater than the length of the guide block 120, the guide block 120 can slide left and right within the guide groove 610. In this way, the relative position between the housing 10 and the cover 600 only needs to be adjusted in one dimension. Thus, through the cooperation of the guide block 120 and the guide groove 610, the relative position between the cover 600 and the housing 100 can be quickly and accurately positioned.

[0038] In some optional embodiments, to prevent the mounting post 300 from axially shifting due to vibrations and impacts generated during vehicle operation, such as... Figure 4 As shown, a pressing rod 620 is provided on the cover 600. When the cover 600 closes the housing 100, the pressing rod 620 presses against the mounting post 300, which can ensure that the elastic straight arm 410 and the mounting post 300 maintain a stable clamping state.

[0039] In addition, this utility model also provides a vehicle controller that uses the aforementioned quick-release circuit board structure.

[0040] In addition, this utility model also provides a vehicle that uses the aforementioned vehicle controller.
