Description

Technical Field

[0001] The utility model relates to the technical field of brushless motor controllers, in particular to a brushless motor controller which is easy to repair. Background Art

[0002] A brushless motor controller is an electronic device used to control and drive the operation of a brushless motor. It uses electrical signals to control the motor's speed, direction, start and stop, and other operations. It is widely used in automobiles, drones, industrial automation and other fields.

[0003] like Figure 1 As shown, the brushless motor controller in the prior art usually includes a housing 1, a controller chip (not shown in the figure) arranged in the housing 1, and an end cover 10 arranged at the end of the housing 1. The end cover 10 and the housing 1 are usually connected and fixed by multiple screws 3. When the controller chip fails, the end cover 10 needs to be disassembled. When disassembling, multiple screws 3 need to be unscrewed, and the operation is relatively cumbersome. In order to improve the efficiency of disassembling the screws 3, the staff usually uses an electric screwdriver 3 to disassemble, which is prone to thread slippage. Therefore, it is necessary to improve the design of the connection method between the housing 1 and the end cover 10 of the brushless motor controller. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a brushless motor controller which is easy to repair.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a brushless motor controller that is easy to repair, comprising a shell, a cover body that cooperates with the shell and forms a box-shaped structure, and a controller chip arranged in the shell, the shell and the cover body are jointly provided with a quick-release connection component, the quick-release connection component comprises two fixed plates fixed on the outer wall of the cover body and arranged in a group, a cylinder body hinged between the two fixed plates, a fixed block fixed on the outer wall of the shell and corresponding to the position of the cylinder body, a positioning block fixed to a side of the fixed block away from the cylinder body, a sliding plate that slidably cooperates with the inner wall of the cylinder, a movable rod fixed to the side wall of the sliding plate close to the fixed block, and a sleeve mounted on the movable rod and The cam is an angular channel that is formed between a pair of camshafts and a pair of camshafts, and the camshafts are connected to a pair of camshafts which are connected to a pair of camshafts, wherein the camshafts are connected to a pair of camshafts and a pair of camshafts.

[0006] By adopting the above technical solution, when the shell and the cover body form a box-shaped structure, under the elastic force of the spring, the side of the positioning column close to the fixed plate is pressed against the inner wall of the side of the positioning hole close to the fixed plate, and the positioning column cooperates with the positioning hole to ensure the stability of the connection between the shell and the cover body. When the controller chip fails, the staff only needs to pull the positioning column through the operating member, and the positioning column pulls the movable plate through the movable rod and compresses the spring. When the positioning column is completely moved out of the positioning hole, the staff only needs to push the operating member to the side away from the shell so that the movable rod moves out from the second notch and the first notch. In this process, the cylinder rotates around the hinge axis between it and the fixed plate, releasing the locking effect between the shell and the cover body, so that the staff can disassemble the cover body to inspect the controller chip, thereby ensuring the normal use of the brushless motor controller. The present application changes the method of fixing the shell and the cover body with multiple screws in the traditional technology, improves the efficiency of disassembling the cover body and repairing the controller chip, avoids the phenomenon that the shell and the cover body are difficult to fix due to screw slippage, and reduces unnecessary trouble.

[0007] Furthermore, the side of the operating member close to the fixing plate is in the shape of a round rod, and the side of the operating member away from the fixing plate is in the shape of a sphere with a diameter larger than the round rod segment.

[0008] By adopting the above technical solution, the shape of the operating member is restricted, which reduces the difficulty for the staff to pull the positioning column toward the side away from the fixed plate through the operating member, which is conducive to the staff to quickly disassemble the cover body.

[0009] Furthermore, the cylinder body comprises a cylinder hinged to two fixed plates arranged in a group and a round cover threadedly connected to one end of the cylinder close to the fixed block.

[0010] By adopting the above technical solution, the round cover and the cylinder are threadedly connected, so that the staff can install the spring and the sliding plate in the cylinder.

[0011] Furthermore, a plurality of anti-slip strips are evenly fixed on the outer wall of the round cover.

[0012] By adopting the above technical solution and providing the anti-slip strip, the probability of slipping occurring when the staff rotates the round cover is reduced.

[0013] Furthermore, the shell and the cover are both U-shaped plate structures, and the box-shaped structure formed by the shell and the cover is in the shape of a rectangular parallelepiped with a hollow interior.

[0014] Furthermore, the quick-release connection components are provided in four groups and are distributed in a rectangular array with respect to the box-shaped structure composed of the shell and the cover.

[0015] By adopting the above technical solution, the side wall of the shell and the side wall of the cover are fitted to each other, and the two together form a hollow rectangular box-shaped structure inside, so that the staff can quickly disassemble the cover after pulling the positioning column out of the positioning hole through the operating member. The four sets of quick-release connection components are distributed in a rectangular array, which enhances the stability of the connection between the cover and the shell.

[0016] Furthermore, one end of the shell is provided with a wire outlet hole for a wire group electrically connected to the controller chip to pass through.

[0017] By adopting the above technical solution, the arrangement of the wire outlet hole makes it easier for the wire group to pass through.

[0018] Furthermore, a transverse plate is fixed on the outer wall of one end of the shell near the bottom of the shell, and two strip-shaped mounting holes are penetrated through the transverse plate.

[0019] By adopting the above technical solution, the arrangement of the horizontal plate and the strip-shaped mounting holes makes it easy for the staff to fix the brushless motor controller by means of bolts and nuts.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the present application, when the controller chip fails, the staff only needs to pull the positioning column through the operating member, and the positioning column pulls the movable plate through the movable rod to compress the spring. When the positioning column is completely moved out of the positioning hole, the staff only needs to push the operating member to the side away from the shell, so that the movable rod moves out from the second notch and the first notch. During this process, the cylinder rotates around the hinge axis between it and the fixed plate, releasing the locking effect between the shell and the cover body, thereby facilitating the staff to disassemble the cover body, so as to overhaul the controller chip and ensure the normal use of the brushless motor controller;

[0022] 2. In the present application, the restriction on the shape of the operating member reduces the difficulty for the staff to pull the positioning column toward the side away from the fixed plate through the operating member, which is conducive to the staff to quickly disassemble the cover body.

The fixed plate 41 is fixed to the outer wall of the cover 2, and two fixed plates 41 are provided and symmetrically arranged. The cylinder 42 includes a cylinder 421 hinged to the two fixed plates 41 arranged in a group and a round cover 422 threadedly connected to one end of the cylinder 421 close to the fixed block 43. The fixed block 43 is a rectangular block structure, which is fixed on the outer wall of the shell 1 and at a position corresponding to the cylinder 42. The positioning block 44 is a round block structure, and the side wall of one side thereof is fixed to the side of the fixed block 43 away from the cylinder 42. The sliding plate 45 is a circular plate structure, which is slidably installed in the cylinder 42 and slidably cooperates with the inner wall of the cylinder 42. The movable rod 46 is a round rod-shaped structure, one end of which is fixed to the side wall of the sliding plate 45 near the fixed block 43, and the movable rod 46 penetrates the side wall of the end cover near the fixed block 43 and slides with the end cover. The spring 47 is sleeved on the movable rod 46 and located in the cylinder 42, and the two ends of the spring 47 are respectively pressed against the inner wall of the cylinder 42 near the fixed block 43 and the side wall of the sliding plate 45 near the fixed block 43. The positioning column 48 is a cylindrical structure, one end of which is fixed to the end of the movable rod 46 away from the sliding plate 45.

The side of the operating member 49 close to the fixed plate 41 is in the shape of a round rod, and the side of the operating member 49 away from the fixed plate 41 is in the shape of a ball with a diameter larger than the round rod segment. When the shell 1 and the cover 2 form a box-shaped structure, under the elastic force of the spring 47, the side of the positioning column 48 close to the fixed plate 41 is pressed against the inner wall of the side of the positioning hole 441 close to the fixed plate 41, and the positioning column 48 cooperates with the positioning hole 441 to ensure the stability of the connection between the shell 1 and the cover 2. When the controller chip 11 fails, the staff only needs to pull the positioning column 48 through the operating part 49, and the positioning column 48 pulls the movable plate through the movable rod 46 to compress the spring 47. When the positioning column 48 is completely moved out of the positioning hole 441, the staff only needs to push the operating part 49 to the side away from the shell 1, so that the movable rod 46 moves out from the second notch 442 and the first notch 431. During this process, the cylinder 42 rotates around the hinge axis between it and the fixed plate 41, releasing the locking effect between the shell 1 and the cover body 2, thereby facilitating the staff to disassemble the cover body 2 for inspection and maintenance of the controller chip 11, thereby ensuring the normal use of the brushless motor controller.The present application changes the conventional method of fixing the shell 1 and the cover 2 with a plurality of screws 3, thereby improving the efficiency of disassembling the cover 2 and repairing the controller chip 11, avoiding the difficulty in fixing the shell 1 and the cover 2 due to thread slippage of the screws 3, and reducing unnecessary trouble.
