Description

Technical Field

[0001] This utility model belongs to the field of sunroof motor technology, and particularly relates to a lightweight direct-drive L-type sunroof motor. Background Technology

[0002] The sunroof motor is the core driving component of the automotive sunroof system. It mainly controls the opening, closing, and tilting of the sunroof glass or sunshade through forward and reverse rotation of the motor. Traditional sunroof motors rely on gear transmission to achieve power transmission, while the direct-drive L-type sunroof motor breaks through this mode by adopting a design that directly drives the load with the motor, eliminating the intermediate transmission device and significantly improving energy efficiency and reliability.

[0003] Traditional L-shaped sunroof motors often employ a flat design (such as a right-angled stator and rotor) to compress space, and are mostly enclosed structures. Their heat dissipation area is relatively smaller than that of traditional motors. If the sunroof is frequently opened and closed (such as in summer when ventilation requirements are high) or is kept in a fully open state for a long time (with the motor kept in a brake-locked state), the temperature of the wiring harness may accumulate and exceed the insulation limit, triggering overheat protection shutdown or aging and short circuit of the enameled wire, thereby affecting the reliability and durability of the motor. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a lightweight direct-drive L-type sunroof motor, which solves the problems of existing L-type sunroof motors, which often adopt a flat design to compress space and are mostly enclosed structures, resulting in a smaller heat dissipation area compared to traditional motors, which can easily lead to overheating protection shutdown or short circuits due to aging of the enameled wire.

[0005] This utility model is implemented as follows: a lightweight direct-drive L-shaped sunroof motor includes a fixed housing, a wiring harness disposed inside the fixed housing, and a movable housing detachably disposed on one side thereof, and further includes:

[0006] The groove is formed on the outer wall of the movable shell;

[0007] A breathable filter element is provided inside the groove so that, after the fixed housing and the movable housing are installed as one unit, the internal air and the external air can circulate, and the dust in the air can be filtered.

[0008] A limiting component is installed between the movable housing and the breathable filter element to lock the position of the breathable filter element.

[0009] As a preferred embodiment of the present invention, the breathable filter element includes an embedded frame adapted to the shape of the groove, and a filter screen is provided on the inner side of the embedded frame.

[0010] As a preferred embodiment of this utility model, the limiting component includes an insertion hole opened on the outer wall of the breathable filter element, and a T-shaped rod is slidably provided on the inner wall of the movable housing.

[0011] In a preferred embodiment of this invention, the diameter of the end of the T-shaped rod near the breathable filter element is the same as the inner diameter of the insertion hole, and the end of the T-shaped rod away from the breathable filter element extends to the outside of the movable housing.

[0012] As a preferred embodiment of this utility model, the end of the T-shaped rod near the air-permeable filter element is provided with an inclined surface, and a reset element is provided between the outer wall of the T-shaped rod and the inner wall of the movable housing.

[0013] As a preferred embodiment of the present invention, a snap-fit ​​assembly is provided between the fixed housing and the movable housing, the snap-fit ​​assembly being used to quickly install the movable housing onto one side of the fixed housing.

[0014] As a preferred embodiment of this utility model, the snap-fit ​​assembly includes elastic rods disposed on the outer wall of the movable housing, and the number of elastic rods is not less than two. An L-shaped groove is provided on the outer wall of the fixed housing, and the number of L-shaped grooves is adapted to the number of elastic rods. A triangular locking block is provided at the end of the elastic rod away from the movable housing.

[0015] As a preferred embodiment of this utility model, the inclination angle A between the shortest side of the triangular block and the side of the elastic rod is greater than 90°, and an extrusion groove is formed on the outer wall of the elastic rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] After the fixed housing and the movable housing are assembled, the ventilation filter of this utility model forms an internal and external air convection channel, allowing relatively cool external air to enter and carry away the heat generated by the wiring harness inside the fixed housing due to frequent switching or braking, preventing the temperature from accumulating and exceeding the insulation limit. At the same time, the ventilation filter can also filter out dust in the incoming air to prevent it from contaminating the interior. The limiting component ensures that the ventilation filter is firmly held in the groove, ensuring the long-term effectiveness of the heat dissipation channel. Attached Figure Description

Detailed Implementation

[0025] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0026] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the lightweight direct-drive L-shaped sunroof motor provided in this embodiment of the present invention includes a fixed housing 100, a wiring harness 200 fixedly installed inside the fixed housing 100, and a movable housing 300 detachably installed on one side thereof.

[0028] Traditional L-shaped sunroof motors often employ a flat design (such as a right-angled stator and rotor) to compress space, and are mostly enclosed structures. Their heat dissipation area is relatively smaller than that of traditional motors. If the sunroof is frequently opened and closed (such as in summer when ventilation requirements are high) or is kept in a fully open state for a long time (with the motor in a brake-locked position), the temperature of the wiring harness 200 inside the fixed housing 100 may accumulate and exceed the insulation limit, triggering overheat protection shutdown or short circuit due to aging of the enameled wire, thereby affecting the overall reliability and durability of the motor.

[0029] Specifically, both the fixed housing 100 and the movable housing 300 are made of lightweight materials, preferably aluminum alloy, which has low density, high strength, and excellent thermal conductivity (suitable for scenarios with high heat dissipation requirements).

[0030] This utility model also includes: a groove 400 formed on the outer wall of the movable housing 300; a breathable filter element 500 detachably installed inside the groove 400, used to fix the housing 100 and the movable housing 300 together, so that the internal air and the external air can circulate and filter dust in the air; and a limiting component 600 installed between the movable housing 300 and the breathable filter element 500, used to lock the position of the breathable filter element 500.

[0031] Specifically, after the fixed housing 100 and the movable housing 300 are assembled, the ventilation filter 500 forms an internal and external air convection channel, allowing relatively cool external air to enter and carry away the heat generated by the internal wiring harness 200 of the fixed housing 100 due to frequent switching or braking, preventing the temperature from accumulating and exceeding the insulation limit. At the same time, the ventilation filter 500 can also filter out dust in the incoming air, preventing it from contaminating the interior. The limiting component 600 ensures that the ventilation filter 500 is firmly held in the groove 400, ensuring the long-term effectiveness of the heat dissipation channel, thereby significantly improving the working stability and service life of the motor under high temperature or high load conditions.

[0032] Reference Figure 2 and Figure 3 The breathable filter element 500 includes an insert frame 501 that is adapted to the shape of the groove 400, and a filter screen 502 is welded or integrally formed on the inner side of the insert frame 501.

[0033] Specifically, the embedded frame 501 has symmetrical slots on the upper and lower sides of its side closest to the outside. Figure 2 As shown in the figure (but not labeled), it is convenient to grasp the insert frame 501 and place it in the groove 400 when installing the entire breathable filter element 500.

[0034] Reference Figure 2 and Figure 3 The limiting component 600 includes an insertion hole 601 opened on the outer wall of the breathable filter 500, and a T-shaped rod 602 slidably disposed on the inner wall of the movable housing 300; the diameter of the end of the T-shaped rod 602 near the breathable filter 500 is the same as the inner diameter of the insertion hole 601, and the end of the T-shaped rod 602 away from the breathable filter 500 extends to the outer side of the movable housing 300; a slope 603 is opened at the end of the T-shaped rod 602 near the breathable filter 500, and a reset member 604 is connected between the outer wall of the T-shaped rod 602 and the inner wall of the movable housing 300.

[0035] Specifically, the reset member 604 is preferably a spring or metal sheet that can withstand pressure, and the reset member 604 can be compressed in the radial direction of the breathable filter 500.

[0036] Specifically, during the process of placing the embedded frame 501 into the groove 400, the embedded frame 501 first presses the inclined surface 603, causing the inclined surface 603 to push the T-shaped rod 602 to move away from the embedded frame 501 and compress the reset member 604. After the embedded frame 501 is completely placed into the groove 400, under the elastic action of the reset member 604, the T-shaped rod 602 extends out again and inserts into the insertion hole 601 on the breathable filter 500 to restrict the axial movement of the breathable filter 500.

[0037] Specifically, when it is necessary to disassemble the embedded frame 501 to clean the filter screen 502 or replace the entire breathable filter element 500, simply pull the T-shaped rod 602 outward to disengage it from the insertion hole 601. In this way, the entire breathable filter element 500 can be removed from the groove 400 without any additional auxiliary tools.

[0038] Reference Figure 1 A snap-fit ​​assembly 700 is installed between the fixed housing 100 and the movable housing 300. The snap-fit ​​assembly 700 is used to quickly install the movable housing 300 onto one side of the fixed housing 100.

[0039] Reference Figure 3 and Figure 5 The snap-fit ​​assembly 700 includes elastic rods 701 that are fixedly installed or welded to the outer wall of the movable housing 300, and the number of elastic rods 701 is not less than two. An L-shaped groove 702 is provided on the outer wall of the fixed housing 100, and the number of L-shaped grooves 702 is adapted to the number of elastic rods 701. A triangular locking block 703 is integrally formed and connected to the end of the elastic rod 701 away from the movable housing 300. The inclination angle A between the shortest side of the triangular locking block 703 and the side of the elastic rod 701 is greater than 90°. An extrusion groove 704 is provided on the outer wall of the elastic rod 701.

[0040] Specifically, during initial alignment, the elastic rod 701 of the movable housing 300 is aligned with the L-shaped groove 702 of the fixed housing 100. The vertical section (entrance end) of the L-shaped groove 702 guides the insertion of the triangular locking block 703. At this time, the triangular locking block 703 is squeezed by the side wall of the L-shaped groove 702, causing the elastic rod 701 to deform slightly. When the triangular locking block 703 completely passes the step, the elastic rod 701 returns to its original position under its own elastic force. The triangular locking block 703 is embedded in the horizontal section of the L-shaped groove 702. At this time, the shortest side of the triangular locking block 703 is engaged with the groove wall, forming a lateral limit to prevent the movable housing 300 from axially separating.

[0041] Specifically, because the sides of the triangular locking block 703 are all inclined, it does not have a single precise "locking" point like a traditional right-angle locking block. Instead, its inclined design allows the triangular locking block 703 to more effectively and widely contact and press against the groove wall of the L-shaped groove 702 during the reset process. This inclined structure provides a "wedge" or "filling" effect. The inclined design allows the triangular locking block 703 to more tightly "fill" the space of the L-shaped groove 702 after reset, reducing local gaps caused by tolerances or assembly deviations (preventing the movable housing 300 from loosening after being installed on one side of the fixed housing 100).

[0042] Specifically, when it is necessary to disassemble the fixed housing 100 and the movable housing 300, press the compression groove 704 on the elastic rod 701 to cause it to deform and bend, thereby causing the triangular locking block 703 to move away from the groove wall of the L-shaped groove 702, so that the elastic rod 701 can be disengaged from the L-shaped groove 702, thereby achieving quick disassembly.

[0043] The working principle of this utility model:

[0044] First, align the elastic rod 701 with the L-shaped groove 702. The vertical section (entrance end) of the L-shaped groove 702 guides the insertion of the triangular locking block 703. At this time, the triangular locking block 703 is squeezed by the side wall of the L-shaped groove 702, causing the elastic rod 701 to deform slightly. After the triangular locking block 703 completely passes the step, the elastic rod 701 returns to its original position under its own elastic force, and the triangular locking block 703 is embedded in the horizontal section of the L-shaped groove 702, completing the installation between the fixed housing 100 and the movable housing 300. Then, grasp the embedding frame 501 and place it in the groove 400. The embedding frame 501 first squeezes the inclined surface 603, causing the inclined surface 603 to push the T-shaped rod 60. 2. Move away from the embedded frame 501 and compress the reset member 604. After the embedded frame 501 is fully placed in the groove 400, under the elastic action of the reset member 604, the T-shaped rod 602 extends out and re-inserts into the insertion hole 601 on the breathable filter 500 to restrict the axial movement of the breathable filter 500. Finally, the present invention is installed in the mounting slot in the car. The setting of the breathable filter 500 forms an internal and external air convection channel, allowing relatively cool external air to enter and carry away the heat generated by the wiring group 200 inside the fixed housing 100 due to frequent switching or braking lock, preventing the temperature from accumulating and exceeding the insulation limit.
