Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a car window swivel drive motor. Background Technology
[0002] In today's automotive industry, power windows have become standard equipment in passenger vehicles. As a core component of power window systems, the market demand for window regulator motors continues to grow. With consumers' increasing demands for vehicle comfort and convenience, the application of window regulator motors is becoming more widespread, further driving market demand.
[0003] When installing existing drive motors, mounting holes are usually reserved on the car door. By setting them on the reduction mechanism, the electric window body can drive the window swing device to operate stably through the reduction mechanism, and the electric window body can also be installed more securely.
[0004] However, due to the different door structures of different car models on the market, the installation space for the drive motor also varies. This means that other parts of the car may interfere with the installation of the drive motor, making it impossible to install the drive motor correctly and greatly increasing the difficulty of installation.
[0005] To address the aforementioned issues, a convenient window regulator motor, as disclosed in patent document CN217643033U, already exists on the market. This patent includes a housing, a fixed blade, an outer casing, a positioning mechanism, and a transmission device. It solves the problem of existing window regulator motors being fixed with special adhesive, requiring a special device to separate the outer casing and the housing during disassembly, resulting in cumbersome operations. By incorporating a positioning mechanism and a transmission device, the housing and outer casing are positioned using a locking block and slot, and then secured with bolts. The transmission device, driven by the motor body, operates a worm gear, worm wheel, transmission rod, and gear set, making installation and disassembly more convenient and improving the device's stability and operating efficiency.
[0006] However, the patent still needs improvement in its structural design. Specifically, the proposed technical solution has several flaws in the snap-fit structure design of the locking block and slot: First, high alignment accuracy is required during installation. If the housing and outer shell are not fully aligned, the locking block may not be able to snap into the slot smoothly, increasing the installation difficulty. Second, it relies on a torsion spring to provide the locking force. After long-term use, the spring is prone to fatigue and loosening, leading to a decrease in the reliability of the snap-fit and the risk of loosening. Third, the fit between the locking block and slot has strict manufacturing tolerance requirements. Improper tolerance control can result in an overly tight fit that is difficult to install or an overly loose fit that is impossible to lock. A large separation force is required during disassembly, which can easily cause mechanical wear on the locking block and slot, affecting the service life of repeated disassembly and assembly. Overall, this snap-fit structure is insufficient in terms of installation convenience, long-term reliability, and durability.
[0007] Therefore, there is an urgent need for a drive motor that can adapt to the door structure of different car models, has a quick positioning and fixing function, and can effectively reduce vibration during operation. In addition, its installation process should be more convenient to improve installation efficiency, reduce installation difficulty, and meet consumers' demand for high-quality automotive parts. Utility Model Content
[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automotive window rolling drive motor that can solve the existing problems.
[0009] To achieve the above objectives, the technical solution of this utility model is as follows: A motor for driving a car window retractor includes: a power window drive assembly; a worm gear reduction mechanism disposed on the power window drive assembly; a motor mounting bracket connected to the worm gear reduction mechanism for fixing the motor to a door panel mounting surface; and an adjustment assembly disposed on the worm gear reduction mechanism for adjusting the mounting angle of the motor mounting bracket. The adjustment assembly includes: an arc-shaped adjustment guide rail disposed on the worm gear reduction mechanism; a T-shaped adjustment slider slidably disposed on the arc-shaped adjustment guide rail and connected to the motor mounting bracket; a locking screw passing through the T-shaped adjustment slider; and a locking plate connected to the locking screw, which is adjusted by rotation. Tightening the locking screw allows the locking plate to engage with the locking slot on the worm gear reducer, thereby fixing the position of the T-shaped adjusting slider. A pre-positioning component, mounted on the motor mounting bracket, is used to pre-position the motor before final tightening. The pre-positioning component includes: a positioning slot mounted on the door sheet metal mounting surface; a quick-positioning block mounted on the motor mounting bracket and matching the positioning slot; a spring-loaded pin located inside the quick-positioning block; and a positioning latch, elastically ejected by the spring-loaded pin, for engaging with a latch fixing hole on the door sheet metal mounting surface when the quick-positioning block is inserted into the positioning slot.
[0010] Furthermore, the locking plate is movably disposed within the locking plate compartment inside the T-shaped adjusting slider, and guide pillars are symmetrically arranged between the locking plate compartment and the locking plate to achieve precise docking with different locking slots.
[0011] Furthermore, the locking screw is threadedly connected to the locking plate, and the end of the locking screw is rotatably connected to the inner wall of the locking plate compartment via a bearing, so that the extension amount and locking force of the locking plate can be precisely controlled when the locking screw is rotated.
[0012] Furthermore, the locking slots are provided in multiple ways. Each locking slot is located on the worm gear reduction mechanism and is arranged along the circumferential direction of the arc-shaped adjustment guide. The end shape of each locking slot matches that of the locking plate, and the spacing between each locking slot is equal, so as to provide multiple discrete and stable installation angle adjustment positions.
[0013] Furthermore, the quick positioning insert has a top pin mounting cavity inside, the positioning pin is movably disposed in the top pin mounting cavity, and the spring top pin is symmetrically disposed between the top pin mounting cavity and the positioning pin to achieve automatic engagement during the insertion process.
[0014] Furthermore, the protruding end of the positioning pin has a wedge-shaped structure, and the shape of the pin fixing hole on the door sheet metal mounting surface matches the wedge-shaped structure of the positioning pin.
[0015] Furthermore, an unlocking lever is connected to the positioning pin, and the unlocking lever passes through a through hole in the side wall of the quick positioning block and extends outward.
[0016] Furthermore, the outer end of the unlocking lever is provided with a shock-absorbing rubber pad.
[0017] Furthermore, the motor mounting bracket is symmetrically provided with bolt through holes for final fixing to the door sheet metal mounting surface. After the initial alignment is completed by the pre-positioning component, a fastening bolt can be used to pass through the bolt through hole and engage with the threaded hole on the door sheet metal mounting surface to achieve final rigid fixing.
[0018] Compared with the prior art, the beneficial effects of this utility model include: 1. When installing the power window drive assembly, in order to adapt to the doors of different car models, the staff controls the T-shaped adjusting slider to slide to the appropriate position in the arc-shaped adjusting guide rail according to the installation position in the door space. Then, by turning the locking screw, the locking plate can be driven into the locking slot to fix the position of the motor mounting bracket. This allows the position of the power window drive assembly to be adjusted, so that the power window drive assembly can be installed in the optimal position, which can effectively avoid interference between the power window drive assembly and other components. 2. To quickly install the power window drive assembly onto the door sheet metal mounting surface, the operator aligns the quick-positioning insert with the positioning slot and inserts it. At this time, the bevel on the positioning pin facilitates the positioning pin's engagement into the pin fixing hole, and the elasticity of the spring top pin ensures that the positioning pin is firmly engaged in the pin fixing hole, thus achieving pre-positioning of the power window drive assembly and facilitating the operator's quick fixation of the power window drive assembly.

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.
[0023] like Figure 1 - Figure 6 As shown, this utility model provides an automotive window control motor, including an electric window drive assembly 1, a worm gear reduction mechanism 2, a motor mounting bracket 5, and a door sheet metal mounting surface 3.

After the initial alignment is completed by the pre-positioning component, a fastening bolt can be passed through the bolt through hole 18 and engaged with the threaded hole on the door sheet metal mounting surface 3 to achieve final rigid fixation.
[0026] In one embodiment of this utility model, the adjustment assembly further includes two sets of motor mounting brackets 5 symmetrically arranged on the T-shaped adjustment slider 4, and the T-shaped adjustment slider 4 is movably disposed within the arc-shaped adjustment guide rail 13. It can be understood that the position of the motor mounting brackets 5 can be adjusted by the cooperation of the T-shaped adjustment slider 4 and the arc-shaped adjustment guide rail 13.
[0027] Meanwhile, a locking plate compartment 16 is provided in the middle of the T-shaped adjusting slider 4, and the locking plate 6 is movably disposed in the locking plate compartment 16. Two sets of guide pillars 17 are symmetrically arranged between the locking plate compartment 16 and the locking plate 6 to achieve precise docking with different locking slots (12). It can be understood that the guide pillars 17 can limit the movement direction of the locking plate 6.
[0028] It should be noted that, based on the above technical concept: 1. When the T-shaped adjusting slider 4 slides within the arc-shaped adjusting guide rail 13, it facilitates the adjustment of the position of the motor mounting bracket 5 by the operator, so that the electric window drive assembly 1 can be installed in the appropriate position. 2. When the motor mounting bracket 5 is moved to the designated position, the locking screw 15 can be turned to drive the locking plate 6 into the locking slot 12, thereby locking the position of the motor mounting bracket 5. 3. By inserting the quick positioning plug 8 into the positioning slot 7, the electric window drive assembly 1 can be pre-positioned. Then, by the elastic force of the spring top pin 20, the positioning pin 11 can be driven into the pin fixing hole 14 to achieve the initial fixation of the electric window drive assembly 1.
[0029] In one embodiment of this utility model, a locking screw 15 is provided in the middle of the locking plate 6, and the locking screw 15 passes through the locking plate 6. One side of the locking screw 15 is located inside the locking plate compartment 16, and the end of the locking screw is rotatably connected to the inner wall of the locking plate compartment through a bearing. It can be understood that by turning the locking screw 15, the locking plate 6 can be moved, and the extension amount and locking force of the locking plate 6 can be precisely controlled when rotating the locking screw 15.
[0030] The worm gear reducer 2 has multiple locking slots 12 corresponding to the locking plate 6. Each locking slot 12 matches the shape of the end of the locking plate 6, and the spacing between the locking slots 12 is equal to provide multiple discrete and stable installation angle adjustment positions. It can be understood that the locking slots 12 and the locking plate 6 cooperate to fix the position of the motor mounting bracket 5.
[0031] In one embodiment of this utility model, the pre-positioning component further includes a quick-positioning insert 8 that matches the positioning slot 7. A top pin mounting cavity 19 is provided inside the quick-positioning insert 8, and a positioning pin 11 is movably disposed within the top pin mounting cavity 19. Two sets of spring top pins 20 are symmetrically arranged between the top pin mounting cavity 19 and the positioning pin 11 to achieve automatic engagement during insertion. It can be understood that the cooperation between the quick-positioning insert 8 and the positioning slot 7 enables pre-positioning of the electric window drive assembly 1.
[0032] In one embodiment of this utility model, a locking hole 14 is provided in the positioning slot 7 corresponding to the positioning pin 11. The protruding end of the positioning pin 11 has a wedge-shaped structure, and the positioning pin 11 matches the locking hole 14. It can be understood that the initial fixation of the position of the drive assembly 1 can be achieved through the cooperation of the positioning pin 11 and the locking hole 14.
[0033] In one embodiment of this utility model, when the T-shaped adjusting slider 4 slides within the arc-shaped adjusting guide rail 13, guide wheels can be provided at both ends of the arc-shaped adjusting guide rail 13 to guide the movement direction of the T-shaped adjusting slider 4. Simultaneously, in a specific implementation, reinforcing ribs can be provided within the locking plate compartment 16, with the reinforcing ribs evenly distributed along the circumference of the locking plate compartment 16, thereby enhancing the structural strength of the locking plate compartment 16.
[0034] Meanwhile, to enhance the structural strength of the motor mounting bracket 5, reinforcing ribs are preferably provided on the motor mounting bracket 5, and the reinforcing ribs are evenly distributed along the circumference of the motor mounting bracket 5. Furthermore, since aluminum alloy has good thermal conductivity and corrosion resistance, it is suitable for use in the automotive environment; therefore, the motor mounting bracket 5 is preferably made of aluminum alloy. Thus, through the above design, the automotive window regulator drive motor provided in this embodiment adopts multiple reinforcement designs in its structure, including the design of reinforcing ribs, guide pillars 17, and locking plate compartment 16, to ensure the stability and durability of the motor during use.
[0035] In the specific implementation of this embodiment: When the electric window drive assembly 1 needs to be installed on the door sheet metal mounting surface 3, since the installation space of the door sheet metal mounting surface 3 varies for different car models, the operator adjusts the angle of the motor mounting bracket 5 by controlling the T-shaped adjusting slider 4 to slide within the arc-shaped adjusting guide rail 13 according to the installation position of the door sheet metal mounting surface 3. This allows for adjustment of the installation position of the electric window drive assembly 1. When the motor mounting bracket 5 is adjusted to the appropriate position, the locking plate 6 and the corresponding locking slot 12 are aligned. Then, by turning the locking screw 15, the locking plate 6 can be driven into the locking slot 12, thus fixing the position of the motor mounting bracket 5. Then, the operator controls the quick positioning insert 8 to be inserted into the positioning slot 7. Because one side of the positioning pin 11 has a certain bevel, it can... This allows the positioning pin 11 to be pressed into the top pin mounting cavity 19 during the process of the quick positioning insert 8 being inserted into the positioning slot 7. After the quick positioning insert 8 is inserted into the positioning slot 7, the positioning pin 11 is aligned with the pin fixing hole 14. At this time, the elastic force of the spring top pin 20 can drive the positioning pin 11 to be inserted into the pin fixing hole 14, thus achieving the initial fixation of the electric window drive assembly 1. This facilitates the subsequent fixation of the electric window drive assembly 1 by the staff. When the positioning pin 11 is inserted into the pin fixing hole 14, the bolt through hole 18 is aligned with the mounting hole on the motor mounting bracket 5, so that the staff can fix the motor mounting bracket 5 to the door sheet metal mounting surface 3 with bolts. The anti-vibration rubber pad 10 can reduce the generation of vibration when the electric window drive assembly 1 is working.
[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
