Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, and in particular to a heat dissipation device for a motor controller housing. Background Technology

[0002] Existing motor controllers include a housing with a heat sink, and a capacitor module, inverter module, main control module, and junction box module installed inside the housing. The housing includes a box, a top cover, and a heat sink. The motor controller is an integrated circuit that actively controls the motor to work according to a set direction, speed, angle, and response time. The motor controller generates heat during operation. If the motor controller cannot be cooled in time, it will affect the use of the motor controller.

[0003] For example, the controller with publication number "CN219761792U" provides a fast heat dissipation controller. This device uses a motor to drive the fan blades to dissipate the heat from the heat sink along the protective mesh, thereby achieving a fast heat dissipation effect and preventing the internal components of the controller from experiencing prolonged high temperatures.

[0004] However, the above-mentioned device still has the following problems in the implementation process: Since the fan is fixedly connected to the outer casing, the air can only blow directly onto the internal circuit board during the heat dissipation process. The contact time with the circuit board is very limited, which greatly reduces the efficiency of removing heat from the circuit board and affects the heat dissipation effect in the motor controller. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a heat dissipation device for the housing of a motor controller to solve the technical problem of poor heat dissipation in the prior art.

[0006] This utility model provides a heat dissipation device for a motor controller housing, comprising: a support block, a controller housing, an angle adjustment component, a baffle plate, and a fan;

[0007] The support block is fixed to the motor housing; the controller housing is fixed to the upper surface of the support block, and the motor's controller circuit board is located inside the controller housing; the fan is vertically installed on one side of the controller housing, blowing air into the controller housing to ventilate and cool the controller circuit board; the angle adjustment component is installed on the controller housing; the baffle is installed inside the controller housing, and the baffle is connected to the adjustable end of the angle adjustment component. The angle adjustment component changes the angle of the baffle inside the controller housing, thereby changing the direction of the airflow blowing the control circuit board.

[0008] Furthermore, the angle adjustment assembly includes: a slider, a rack, a gear, and a connecting shaft; a slot penetrating the controller housing is provided on the controller housing along the air inlet direction; the slider is engaged in the slot and can be controlled to move within the slot to change its fixed position; the rack is disposed within the controller housing along the air inlet direction, with its bottom connected to the slider and moving with the slider; the gear is vertically disposed within the controller housing relative to the rack tooth surface and meshes with the rack; the connecting shaft is connected to the gear along the central axis of the gear and rotates with the gear; one end of the baffle is sleeved on the connecting shaft and rotates with the connecting shaft to change the airflow direction of the purging control circuit board.

[0009] Furthermore, the heat dissipation device of the motor controller housing also includes a filter screen; the filter screen is disposed on the controller housing at the front end of the fan and is arranged parallel to the fan.

[0010] Furthermore, the heat dissipation device of the motor controller housing also includes: a connecting rod and a cleaning rod; the filter screen has grooves extending through it along the height direction on both sides of the screen surface; one end of the connecting rod slides along the groove; the connecting rod is horizontally positioned, or the end of the connecting rod in the groove is inclined downwards at a higher position; the cleaning rod is mounted between the other ends of the two connecting rods, and moves along the height direction of the filter screen with the connecting rod to clean the dust accumulated on the surface of the filter screen.

[0011] Furthermore, the sweeping rod includes: a connecting rod, a limiting block, a sweeping block, and a torsion spring; the sweeping block is strip-shaped with an isosceles trapezoidal side section; the connecting rod extends through the top of the trapezoidal sweeping block along its extension direction, and is mounted between the two connecting rods, allowing the sweeping block to rotate around the connecting rod as an axis; the torsion spring is sleeved at both ends of the connecting rod, providing a rebound force to the sweeping block; the limiting block is located at one end of the connecting rod, limiting the rebound angle of the sweeping block.

[0012] Furthermore, the heat dissipation device of the motor controller housing also includes: an elastic cloth; one side of the elastic cloth is connected to the lower edge of the fan, and the opposite side is connected to one end of the connecting rod in the slide groove. The elastic cloth unfolds or retracts with the movement of the connecting rod to block the dust from the cleaning filter.

[0013] Furthermore, the heat dissipation device of the motor controller housing also includes a collection box; the bottom of the controller housing between the fan and the filter screen is recessed downward to form a groove, and the collection box is removably installed in the groove to collect the dust from cleaning the filter screen.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses an angle adjustment component to change the angle of the baffle, thereby obstructing the airflow from the fan and further increasing the contact time between the flowing air and the circuit board. This allows for more thorough heat exchange between the circuit board and the air, improving heat dissipation efficiency.

[0016] This invention improves safety during filter cleaning by raising the elastic cloth to further prevent dust from drifting onto the circuit board and causing damage. Furthermore, the dust collected in the collection box is centrally processed, reducing the impact on the controller housing during cleaning and facilitating dust removal for staff, thus enhancing the practicality of this heat dissipation structure.

[0017] This invention, by moving upwards to clean the filter screen and downwards to clean the heat dissipation mesh, further allows the cleaned dust to enter the collection box more effectively, preventing dust from scattering in the air during the cleaning process. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The present invention will be further illustrated below with reference to specific embodiments. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Modifications to the present invention in various equivalent forms all fall within the scope defined by the appended claims.

[0028] Example 1:

[0029] like Figure 1-6 As shown, the present invention provides a heat dissipation structure for a motor controller housing, comprising: a motor component 1, a connecting block 3 fixedly connected to the outer surface of the motor component 1, a controller housing 2 fixedly connected to the upper end face of the connecting block 3, a through slot opened on the end surface of the controller housing 2, a filter screen 4 fixedly connected to the wall of the slot, and a controller circuit board 15 fixedly connected to the inner wall of the controller housing 2, a mounting bracket 8 fixedly connected to the inner wall of the controller housing 2 near the filter screen 4, a fan 10 fixedly connected to the inner wall of the mounting bracket 8, and the fan 10 being fixedly connected to the surface of the controller circuit board 15 via a wire.

[0030] More specifically, in this embodiment: during use, the power supply components in the controller circuit board 15 provide power to the rotation of the fan 10, and then the rotation of the fan 10 further drives the internal airflow, thereby carrying away the heat generated in the controller circuit board 15, thus avoiding the possibility of the controller circuit board 15 burning out due to high temperature during long-term operation.

[0031] Example 2:

[0032] Based on Embodiment 1, in this embodiment: a sliding groove 6 extending into the interior is provided on the upper end face of the controller housing 2. A sliding column 20 is slidably connected to the groove wall of the sliding groove 6. A sliding disk 5 is fixedly connected to the upper end face of the sliding column 20. The lower end face of the sliding disk 5 is slidably connected to the upper end face of the controller housing 2. A sliding plate 7 is fixedly connected to the lower end face of the sliding column 20. The upper end face of the sliding plate 7 is slidably connected to the inner upper end face of the controller housing 2. A straight tooth row 19 is fixedly connected to the side end face of the sliding plate 7. The side of the straight tooth row 19 is slidably connected to the inner wall of the controller housing 2. A toothed ring 16 is also meshed with the toothed surface of the straight tooth row 19. A rotating rod 18 is fixedly connected to the inner wall of the toothed ring 16. The end face of the rotating rod 18 is rotatably connected to the inner wall of the controller housing 2. A wind baffle 17 is also fixedly connected to the surface of the rotating rod 18.

[0033] More specifically, in this embodiment: during use, by pushing the sliding disk 5 to move, the sliding column 20 is further driven to slide in the sliding groove 6, thereby driving the sliding plate 7 to move. During the movement of the sliding plate 7, the straight tooth row 19 is driven to move, which in turn drives the toothed ring 16 to drive the rotating rod 18 to rotate, thereby changing the angle of the baffle 17, obstructing the wind blown by the fan 10, further increasing the contact time between the flowing air and the controller circuit board 15, so that the heat exchange between the controller circuit board 15 and the air is more thorough and the heat dissipation efficiency is improved.

[0034] Example 3:

[0035] Based on Embodiments 1 and 2, in this embodiment: a sliding groove 22 is provided on the side of the filter screen 4, and a sliding post 21 is slidably connected to the groove wall of the sliding groove 22. An elastic cloth 14 is fixedly connected to the end face of the sliding post 21 inside the controller housing 2, and the end of the elastic cloth 14 away from the sliding post 21 is fixedly connected to the inner wall of the controller housing 2.

[0036] More specifically, in this embodiment: by setting the elastic cloth 14, the elastic cloth 14 is raised during the dust cleaning process, further preventing the dust swept down from drifting onto the controller circuit board 15 and causing damage to the controller circuit board 15, thereby improving the safety when cleaning the dust on the filter screen 4.

[0037] Example 4:

[0038] Based on embodiments one to three, in this embodiment: a trough 12 is provided below the elastic cloth 14, a collection box 13 is provided below the trough 12, a handle 11 is fixedly connected to the outer surface of the collection box 13, and the upper end face of the collection box 13 is slidably connected to the lower end face of the controller housing 2.

[0039] More specifically, in this embodiment, the dust swept off will fall into the collection box 13 for centralized processing, thereby reducing the impact on the controller housing 2 during the dust cleaning process, and also making it easier for staff to clean the dust, further improving the practicality of this heat dissipation structure.

[0040] Example 5:

[0041] Based on embodiments one to four, in this embodiment: a connecting post 27 is fixedly connected to the end face of the sliding post 21 away from the elastic cloth 14; a connecting plate 9 is fixedly connected to the end face of the connecting post 27 away from the sliding post 21; a fixing block 26 is fixedly connected to the end face of the connecting plate 9 facing the filter screen 4; a through groove is opened on the end face of the fixing block 26; a fixing rod 29 is fixedly connected to the wall of the through groove; a trapezoidal cleaning block 24 is rotatably connected to the surface of the fixing rod 29; a limiting plate 28 is fixedly connected to the surface of the trapezoidal cleaning block 24; the surface of the limiting plate 28 abuts against a limiting plate 23; the surface of the limiting plate 23 is also fixedly connected to the surface of the fixing block 26; a torsion spring 25 is also fixedly connected to the surface of the fixing block 26; and the other end of the torsion spring 25 is fixedly connected to the end face of the trapezoidal cleaning block 24.

[0042] More specifically, in this embodiment: the connecting plate 9 drives the connecting column 27 to move, further causing the sliding column 21 to slide within the sliding groove 22, thereby driving the trapezoidal cleaning block 24 to move upward. During the upward movement of the trapezoidal cleaning block 24, since the end of the trapezoidal cleaning block 24 facing the filter screen 4 is inclined, it will rotate counterclockwise around the fixed rod 29 as an axis due to the pressure from the filter screen 4, thereby causing the torsion spring 25 to deform. At this time, the trapezoidal cleaning block 24 does not clean the filter screen 4 and drives the filter... When the filter screen 4 rises, the trapezoidal cleaning block 24 rotates under the action of the torsion spring 25. Due to the action of the first limiting plate 28 and the second limiting plate 23, the trapezoidal cleaning block 24 rotates clockwise within a limited range, so that the lower end of the trapezoidal cleaning block 24 abuts against the surface of the filter screen 4, thereby cleaning the filter screen 4. By moving upward without cleaning the filter screen 4 and moving downward to clean the filter screen 4, the cleaned dust can be better collected into the collection box 13, preventing the dust from flying in the air during the cleaning process.

[0043] The working principle of this utility model in a specific embodiment is as follows:

[0044] In use, the power supply components within the controller circuit board 15 provide power to the fan 10, which in turn drives the internal airflow, carrying away the heat generated within the controller circuit board 15. This movement of the sliding disc 5 further moves the sliding column 20 within the sliding groove 6, causing the sliding plate 7 to move. During this movement, the straight toothed rack 19 moves, causing the toothed ring 16 to rotate the rotating rod 18, thus changing the angle of the baffle 17 and obstructing the airflow from the fan 10. This further increases the contact time between the flowing air and the controller circuit board 15, resulting in more thorough heat exchange between the controller circuit board 15 and the air. When cleaning the filter 4, the connecting plate 9 moves the connecting column 27, causing the sliding column 21 to slide within the sliding groove 22, thereby moving the trapezoidal cleaning block 24 upwards. As the trapezoidal cleaning block 24 moves upward, its end facing the filter screen 4 is inclined. When moving upward, it is squeezed by the filter screen 4 and rotates counterclockwise around the fixed rod 29, causing the torsion spring 25 to deform. At this time, the trapezoidal cleaning block 24 does not clean the filter screen 4 and instead lifts it up. When moving downward, the trapezoidal cleaning block 24 rotates under the action of the torsion spring 25. Due to the action of the limiting plate 28 and the limiting plate 23, the trapezoidal cleaning block 24 rotates clockwise within a limited range, causing its lower end to contact the surface of the filter screen 4, thus cleaning the filter screen 4. The cleaned dust, blocked by the elastic cloth 14, falls into the collection box 13 for centralized processing, reducing the impact on the controller housing 2 during cleaning and facilitating dust removal by staff. Finally, staff collect the dust from the collection box 13.

[0045] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the appended claims.
