Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle controller technology, and in particular to an electric motorcycle controller with a heat dissipation structure. Background Technology

[0002] As the core control component of an electric motorcycle, the controller is responsible for regulating the motor's speed, torque, and energy recovery. Its performance directly affects the electric motorcycle's power output, range, and operational safety. Because the controller generates a significant amount of heat during high-frequency, high-current operation, if this heat cannot be dissipated in time, the temperature of the internal components will rise, affecting its stability and lifespan. Therefore, controllers with heat dissipation structures are standard equipment on electric motorcycles.

[0003] A search revealed that Chinese announcement number CN222692153U discloses an electric motorcycle controller with a heat dissipation structure, belonging to the technical field of electric motorcycle controllers. This controller includes a controller housing, a water-cooling plate, and a cover plate. The water-cooling plate is fitted into the slot of the controller housing and fixed with bolts. The front of the water-cooling plate has several mounting holes for fixing electronic components, and the back of the water-cooling plate has cooling channel grooves. The side of the water-cooling plate has an inlet and an outlet end communicating with the cooling channel grooves. The cover plate covers the cooling channel grooves and is fixed to the water-cooling plate with screws. The water-cooling plate is used to mount electronic components; therefore, it can absorb heat immediately. The continuously flowing coolant within the water-cooling plate rapidly cools it, preventing the controller from overheating during operation, resulting in more stable output power and extending the lifespan of the electronic components inside the controller housing.

[0004] However, in actual use, while the controller housing is well-sealed and not easily infiltrated by water and dust, the messy wiring harness lacks fixation and organization. During the operation of the electric motorcycle, it will rub against the controller housing, frame, or other components. The outer insulation layer of the wiring harness is easily worn and scratched, resulting in exposed internal wires that come into contact with other metal parts, causing short circuits and circuit failures. If the short circuit occurs on a high-voltage line, it will also generate electric sparks and may even ignite nearby flammable materials. To address the above problems, an electric motorcycle controller with a heat dissipation structure is proposed. Utility Model Content

[0030] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0031] Reference Figures 1 to 3 This utility model provides a technical solution: an electric motorcycle controller with a heat dissipation structure, including a controller body 1. The controller body 1 is the core of the entire controller, responsible for receiving control signals from the electric vehicle and controlling the motor 41 according to the signal commands to ensure the normal operation of the electric motorcycle. Multiple mounting through holes 2 are provided on the outer right side of the controller body 1. The main function of the mounting through holes 2 is to provide a channel for the electric motorcycle's wiring harness to pass through, allowing the wiring harness to enter the controller body 1 in an orderly manner and connect with electronic components, avoiding the wiring harness from becoming tangled and facilitating later inspection and maintenance. Multiple wiring harness organizing mechanisms 3 are fixedly connected to the outer right side of the controller body 1, and a mounting mechanism 4 is fixedly connected to the outer bottom of the controller body 1. The mounting mechanism 4 includes a motor 4. 1. The motor 41 serves as the power source for the mounting mechanism 4, providing stable driving force. By rotating forward and backward, it drives the drive rod 42 to rotate, thereby enabling the extension and retraction of the positioning mounting plate 47 to adapt to the installation size requirements of different frames. The outer bottom end of the motor 41 is fixedly connected to the bottom of the controller body 1. The drive end of the motor 41 is fixedly connected to the drive rod 42. The main function of the drive rod 42 is to transmit the rotational motion of the motor 41 to the rotating plate 43. It is an intermediate component for power transmission, ensuring that the driving force of the motor 41 can be efficiently transmitted to the subsequent moving parts. The drive rod 42 is fixedly connected to the rotating plate 43, which converts the rotational motion of the drive rod 42 into the swing motion of the follower plate 44. The follower plate 44 is driven to move synchronously through the shaft holes at both ends, realizing the transmission of force and the conversion of direction.

[0032] Both the left and right sides of the rotating plate 43 are rotatably connected to follower plates 44, which further convert the rotational motion of the rotating plate 43 into the linear reciprocating motion of the sliding plate 45, thereby driving the support rod 46 and the positioning mounting plate 47 to extend and retract. The other end of the follower plate 44 is fixedly connected to the sliding plate 45, which converts the swinging motion of the follower plate 44 into the linear motion of the support rod 46, thereby driving the positioning mounting plate 47 to move and adjust the installation position. The bottom outer end of the sliding plate 45 is fixedly connected to the support rod 46, which converts the swinging motion of the follower plate 44 into the linear motion of the support rod 46, thereby driving the positioning mounting plate 47 to move and adjust the installation position. The bottom outer end of the support rod 46 is fixedly connected to the positioning mounting plate 47. The main function of the strut 46 is to connect the sliding plate 45 and the positioning mounting plate 47, transmit the movement of the sliding plate 45 to the positioning mounting plate 47, and provide support for the positioning mounting plate 47 to ensure that the positioning mounting plate 47 can move smoothly and bear the weight of the controller. Multiple heat dissipation fins 5 are fixedly connected to the outside of the controller body 1. The main function of the heat dissipation fins 5 is to increase the contact area between the controller body 1 and the air. When the controller is working, the heat generated by the internal electronic components will be transferred to the heat dissipation fins 5 through the controller body 1, and then the heat will be dissipated to the surrounding environment through heat exchange between the fins and the air, thereby reducing the operating temperature of the controller, preventing the electronic components from being damaged due to overheating, and ensuring the stable operation and service life of the controller.

[0033] The wire harness organizing mechanism 3 includes four fixing rods 31. The main function of the fixing rods 31 is to provide stable installation support for the upper clamping plate 36 and the lower clamping plate 35. Through their own rigid structure, they connect the upper and lower clamping plates 35 into a whole, ensuring that the wire harness organizing mechanism 3 maintains structural stability under vehicle vibration environment and providing a reliable installation foundation for subsequent wire harness fixing components. The upper clamping plate 36 is externally fixed to the top fixing rod 31. The upper clamping plate 36 and the lower clamping plate 35 correspond vertically to each other, forming a clamping space for the wire harness. The semi-circular groove at the bottom can fit against the outer surface of the wire harness. With the cooperation of the rotating clamping plate 34, it achieves the initial fixing of the wire harness and prevents the wire harness from shifting laterally during the organizing process. Connecting brackets 32 are fixedly connected to both the front and rear sides of the outer side of the clamping plate 36. The main function of the connecting brackets 32 is to provide mounting points for the connecting shaft 33 and the rotating clamping plate 34, ensuring that the rotating clamping plate 34 can rotate flexibly around the connecting shaft 33. At the same time, the rigid structure of the connecting brackets 32 bears the clamping force transmitted by the rotating clamping plate 34, ensuring that the rotating clamping plate 34 will not deform when pressure is applied to the wire harness. The connecting shaft 33 is rotatably connected inside the connecting brackets 32. The connecting shaft 33 serves as the rotation center of the rotating clamping plate 34, providing stable rotational support for the rotating clamping plate 34, allowing the rotating clamping plate 34 to swing freely around its axis, thereby realizing the clamping and releasing action of the wire harness and ensuring that the rotation process is smooth and without jamming.

[0034] A rotating clamping plate 34 is rotatably connected to the outside of the connecting shaft 33. The rotating clamping plate 34 can rotate downward around the connecting shaft 33 under external force. When it rotates to contact the lower clamping plate 35, the groove at its bottom engages with the slot of the upper clamping plate 36, firmly clamping the wire harness in the middle. The rubber anti-slip pad increases the friction with the wire harness and prevents the wire harness from slipping. The lower clamping plate 35 is fixedly connected to the outside of the bottom fixing rod 31. The lower clamping plate 35 serves as the lower support component for wire harness arrangement. It works with the upper clamping plate 36 and the rotating clamping plate 34 to form a complete wire harness clamping structure. The slot at its top provides a lower support surface for the wire harness. A telescopic rod 37 is fixedly connected inside the lower clamping plate 35. The main function of the telescopic rod 37 is to provide guide support for the installation spring 38, ensuring that the installation spring 38 can only extend and retract in the vertical direction, avoiding lateral bending of the spring under force. At the same time, it restricts the movement trajectory of the retaining ring 39, allowing the retaining ring 39 to accurately contact the wire harness and extend and retract. The main function of the rod 37 is to provide guide support for the mounting spring 38, ensuring that the mounting spring 38 can only extend and retract in the vertical direction, avoiding lateral bending of the spring when under force, and limiting the movement trajectory of the retaining ring 39 so that the retaining ring 39 can accurately contact the wire harness. The mounting spring 38 is sleeved on the outside of the telescopic rod 37. When the wire harness is put into the slot, the mounting spring 38 will automatically adjust the compression amount according to the diameter of the wire harness, providing upward elastic pressure to the wire harness, so that the wire harness fits tightly in the slot of the upper plate 36 and the groove of the rotating plate 34, enhancing the firmness of the wire harness fixation. The retaining ring 39 is fixedly connected to the outside of the telescopic rod 37, and the positioning component 310 is slidably connected to the outside of the lower plate 35. The positioning component 310 includes a sliding clamping rod 3101. When the rotating plate 34 clamps the wire harness, the wedge-shaped clamping head of the sliding clamping rod 3101 can be inserted into the preset positioning hole of the rotating plate 34 to lock the rotating plate 34 in the clamping position and prevent it from springing back.

[0035] The sliding lever 3101 is externally slidably connected to the outside of the lower clamping plate 35. The lower clamping plate 35 has a cavity 3102 inside. The inner wall of the cavity 3102 is smoothed to reduce frictional resistance when the limiting plate 3103 slides, and also guides the sliding of the sliding lever 3101, ensuring its precise movement trajectory. The limiting plate 3103 is slidably connected inside the cavity 3102, limiting the sliding stroke of the sliding lever 3101 and preventing it from completely disengaging from the lower clamping plate 35. It also serves as a return spring 31. 04 provides a force fulcrum, evenly transmitting the spring force to the sliding lever 3101. A return spring 3104 is sleeved on the outside of the sliding lever 3101. When the sliding lever 3101 is pulled to disengage from the rotating plate 34, the return spring 3104 is compressed and stores elastic potential energy. After the pull ring is released, the return spring 3104 releases its potential energy, pushing the limit plate 3103 and the sliding lever 3101 to automatically reset, so that the head of the sliding lever 3101 re-engages into the positioning hole of the rotating plate 34, realizing the automatic locking function of the positioning component 310.

[0036] Reference Figures 2 to 4 Limit blocks 48 are fixedly connected to the four corners of the bottom of the controller body 1. The main function of the limit blocks 48 is to precisely limit the sliding trajectory of the sliding plate 45. When the sliding plate 45 moves left and right under the drive of the follower plate 44, the groove on the inner side of the limit block 48 will constrain the movement direction of the sliding plate 45 to prevent it from shifting up or down or tilting. The outer side of the sliding plate 45 is slidably connected to the outside of the limit block 48. The inner side of the limit plate 3103 is fixedly connected to the outside of the sliding rod 3101. The outer side of the sliding rod 3101 is slidably connected to the inside of the cavity 3102. The upper plate 3... The outer bottom end of 6 contacts the outer top end of the lower clamping plate 35, and the outer bottom end of the top clamping ring 39 contacts the outer top end of the bottom clamping ring 39. One end of the return spring 3104 is fixedly connected to the outside of the limiting plate 3103, and the other end of the return spring 3104 is fixedly connected to the inside of the cavity 3102. When the sliding clamping rod 3101 is released, the return spring 3104 will release elastic potential energy, pushing the limiting plate 3103 and the sliding clamping rod 3101 to move closer to the rotating clamping plate 34, so that the sliding clamping rod 3101 can automatically engage in the positioning hole of the rotating clamping plate 34.

[0037] Working principle: When tidying up the wire harness, by pulling the sliding lever 3101, the sliding lever 3101 slides inside the cavity 3102 through the limiting plate 3103. Then, the outside of the limiting plate 3103 can squeeze the return spring 3104, which in turn can deform the return spring 3104. Then, the sliding lever 3101 slides, which allows the rotating plate 34 to be pulled out from the lower plate 35. Then, the wire harness can be tidyed up by the retaining ring 39. At this time, by locking the rotating plate 34 with the lower plate 35, and then by releasing the sliding lever 3101, the return spring 3104 rebounds, which allows the rotating plate 34 to lock with the sliding lever 3101, thus achieving the clamping and tidying up of the wire harness.

[0038] When installing the controller body 1, the drive motor 41 drives the drive rod 42 to rotate, which in turn drives the rotating plate 43 to rotate. The rotating plate 43 then drives the follower plate 44 to rotate, which in turn drives the sliding plate 45 to slide inside the limit block 48. The sliding plate 45, through the support rod 46, drives the limit block 48 to be fixed in the designated position of the controller body 1, thus enabling the installation of the controller body 1.
