Technical Field

[0001] This utility model relates to the field of motor control technology, specifically to a motor controller. Background Technology

[0002] A motor controller is a device or system used to control the operation of an electric motor. It typically includes a series of electronic components, sensors, and software to monitor the motor's operating status, adjust its speed, direction, and torque, and ensure that the motor operates within a safe and efficient range. Motor controllers can be applied to various types of electric motors, including DC motors, AC motors, and stepper motors. In industries such as industrial applications, transportation, and household appliances, motor controllers play a crucial role, enabling precise control and regulation of motor operation, thereby improving equipment performance and efficiency.

[0003] A motor controller disclosed in the China Patent Network authorized announcement number (CN104780736B) uses phase change material to absorb heat, which slows down the temperature rise and gives the outer surface of the casing more time to dissipate heat.

[0004] In this application, when the motor controller is used for a long time, the electronic components inside the motor controller are easily damaged (due to aging), and the internal electronic components need to be repaired. However, it is inconvenient for staff to disassemble the motor controller, and the disassembly is cumbersome and inconvenient for personnel to operate. Therefore, a motor controller is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a motor controller to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a motor controller, comprising a housing and a base plate, wherein four sets of blind holes are provided at the front and rear edges of the bottom of the housing, and a locking post fixed to the upper surface of the base plate is fitted in each set of blind holes. Two sets of limiting grooves are provided between adjacent sets of blind holes along the length direction of the base plate, and two sets of locking strips are slidably provided in each set of limiting grooves. A locking slot is provided at the position where the locking post contacts the locking strip. Springs are fixed to the ends of the two sets of locking strips, and a handle extending to the outside of the housing is fixed to the outer wall of each set of locking strips.

[0007] As a preferred technical solution, the front surface of the box is fixed with two sets of locking components. The locking components include a connecting cylinder fixedly connected to the front surface of the box. A base rod fixed to the front surface of the box is provided above the connecting cylinder. Two sets of connecting arms are rotatably sleeved on the outer wall of the base rod. A plate arc plate located on the end face of the connecting cylinder is fixed on the outer wall of each set of connecting arms.

[0008] As a preferred technical solution, the connecting cylinder is fitted with a wire harness that connects to the electronic components inside the box, and one end of the wire harness located inside the connecting cylinder is connected to a terminal block.

[0009] As a preferred technical solution, a torsion spring is installed at the contact position between the connecting arm and the outer wall of the base rod, and the two sets of connecting arms are symmetrically arranged about the axis of the base rod.

[0010] As a preferred technical solution, the two sets of plate arc plates form a ring on the outer wall of the wire harness, and the inner wall diameter of the ring is smaller than the outer wall diameter of the terminal on the end face of the wire harness.

[0011] As a preferred technical solution, the front and rear surfaces of the box body are provided with a sliding groove that communicates with the limiting groove, and two sets of handles fixed to the outer wall of the card strip are slidably provided in the sliding groove.

[0012] As a preferred technical solution, the upper surface of the box body is provided with four sets of threaded holes, which are distributed at the top of the box body near the external corner.

[0013] In summary, the present invention has the following main advantages:

[0014] This utility model, through the cooperation of the locking posts and locking strips, makes the disassembly of the box and the base plate quick and easy, and facilitates the manual disassembly of the controller for maintenance work. At the same time, under the protection of the locking components, the wiring harness of the controller connected to the outside circuit is secure, can withstand a certain amount of external force and will not fall off, so that the motor controller can monitor and adjust the motor at all times.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A motor controller, such as Figures 1 to 5 As shown, the box includes a box body 100 and a bottom plate 110. Four sets of blind holes 150 are opened at the bottom of the box body 100 at the front and rear edges. Each set of blind holes 150 is fitted with a locking post 130 fixed to the upper surface of the bottom plate 110. Two sets of limiting grooves 151 are opened between two adjacent sets of blind holes 150 along the length of the bottom plate 110. Two sets of locking strips 140 are slidably arranged in each set of limiting grooves 151. A locking slot 131 is opened at the position where the locking post 130 contacts the locking strip 140. Springs 142 are fixed to the ends of the two sets of locking strips 140. A handle 141 extending to the outside of the box body 100 is fixed to the outer wall of each set of locking strips 140.

[0024] Two sets of locking components 120 are fixed on the front surface of the box body 100. The locking components 120 include a connecting cylinder 121 fixedly connected to the front surface of the box body 100. A base rod 122 fixed to the front surface of the box body 100 is provided above the connecting cylinder 121. Two sets of connecting arms 123 are rotatably sleeved on the outer wall of the base rod 122. A plate arc piece 124 located on the end face of the connecting cylinder 121 is fixed on the outer wall of each set of connecting arms 123.

[0025] The inner sleeve of the connecting tube 121 is provided with a wire harness 160 that connects to the electronic components inside the box 100. One end of the wire harness 160 located inside the connecting tube 121 is connected to a terminal block.

[0026] A torsion spring is fitted at the contact position between the connecting arm 123 and the outer wall of the base rod 122, and the two sets of connecting arms 123 are symmetrically arranged about the axis of the base rod 122.

[0027] When repairing the electrical components inside the box 100, apply external force to the two sets of retaining strips 140 on the front and rear surfaces of the box 100 simultaneously with both hands. At this time, the retaining strips 140 slide in a straight line relative to each other in the limiting groove 151, and the ends of the retaining strips 140 will fall out from the blind hole 150 and no longer engage with the retaining slot 131. At this time, the locking effect on the retaining post 130 has been released. Then, apply external force to the side of the box 100 away from the bottom plate 110 with both hands, and the box 100 can be removed from the top of the bottom plate 100, so that the internal electronic components can be repaired conveniently.

[0028] When connecting the wire harness 160 to the electronic components inside the housing 100, the two sets of connecting arms 123 need to be swung outwards to both sides. The connecting arms 123 rotate around the axis of the base rod 122, compressing the torsion spring between them. The plate arc sheet 124 will then be in an unfolded state, as shown in the instruction manual. Figure 5 As shown, the terminal at the end of the wire harness 160 can be inserted into the connecting cylinder 121 to connect the circuit with the internal electronic components. When the external force applied to the connecting arm 123 is removed, the torsion spring will restore the connecting arm 123 and the plate arc 124, thereby wrapping around the outer wall of the wire harness 160 and constraining the terminal so that it can withstand a certain external force, thereby ensuring that the motor controller can detect the motor at all times.

[0029] Please refer to this carefully. Figure 2 and Figure 5 The two sets of plate arc plates 124 form a ring on the outer wall of the wire harness 160, and the inner wall diameter of the ring is smaller than the outer wall diameter of the terminal on the end face of the wire harness 160.

[0030] It can wrap the end of the terminal away from the box 100, withstand a certain external tension, and make the connection between the wire harness 160 and the box 100 firm.

[0031] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The front and rear sides of the box body 100 are provided with a sliding groove that communicates with the limiting groove 151, and two sets of handles 141 fixed to the outer wall of the card strip 140 are slidably provided in the sliding groove.

[0032] Applying a relatively close external force to the two sets of handles 141 with your hand will bring the two sets of locking strips 140 closer together, thus separating the box body 100 and the base plate 110.

[0033] Please refer to this carefully. Figure 1 and Figure 2 The upper surface of the box 100 has four sets of threaded holes, which are distributed at the top of the box 100 near the external corner.

[0034] The bolts can be screwed into the threaded holes to fix the motor controller on the support, enabling it to monitor and regulate the motor.

[0035] When using the box 100, to repair the electrical components inside, apply external force to the two sets of retaining strips 140 on the front and rear surfaces of the box 100 simultaneously with both hands. At this time, the retaining strips 140 slide in a straight line relative to each other in the limiting groove 151, and the ends of the retaining strips 140 will fall out from the blind hole 150 and no longer engage with the retaining slot 131. At this time, the locking effect on the retaining post 130 has been released. Then, apply external force to the side of the box 100 away from the bottom plate 110 with both hands, and the box 100 can be removed from the top of the bottom plate 100, so that the internal electronic components can be repaired conveniently.

[0036] When connecting the wire harness 160 to the electronic components inside the housing 100, the two sets of connecting arms 123 need to be swung outwards to both sides. The connecting arms 123 rotate around the axis of the base rod 122, compressing the torsion spring between them. The plate arc sheet 124 will then be in an unfolded state, as shown in the instruction manual. Figure 5 As shown, the terminal at the end of the wire harness 160 can be inserted into the connecting cylinder 121 to connect the circuit with the internal electronic components. When the external force applied to the connecting arm 123 is removed, the torsion spring will restore the connecting arm 123 and the plate arc 124, thereby wrapping around the outer wall of the wire harness 160 and constraining the terminal so that it can withstand a certain external force, thereby ensuring that the motor controller can detect the motor at all times.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
