Description

Technical Field

[0001] This invention belongs to the field of automotive glass and screen lifting technology, specifically an automotive glass and screen control lifting device. Background Technology

[0002] Window regulators are the devices used to raise and lower car windows, and they are mainly divided into two categories: electric window regulators and manual window regulators. Many cars now use electric window regulators.

[0003] Structurally, electric window regulators can be broadly classified into boom-type electric window regulators and flexible electric window regulators. Boom-type electric window regulators employ a cantilever support structure and a gear and toothed plate mechanism, resulting in higher working resistance. The transmission mechanism of boom-type electric window regulators is a gear and toothed plate meshing transmission. Except for the gears, its main components are plate structures, which are easy to manufacture and have low cost, making them commonly used in vehicles.

[0004] During vehicle use, it's sometimes necessary to open windows for ventilation to maintain driving comfort. However, insects, catkins, and even sand can enter the car, affecting the driving experience and safety. The traditional solution is to install window screens. Current screens are generally embedded in the inner edge of the window or fixed in a way that covers the entire window area. These screens cannot be easily adjusted in height, meaning they cannot be switched between simultaneous or separate raising and lowering of the glass and screen, making them impractical. Furthermore, switching between using and not using the screen requires frequent removal and installation, which can easily lead to damage and reduced lifespan. This frequent removal and installation is cumbersome and inconvenient, significantly diminishing the driving experience. Summary of the Invention

[0005] To address the problems of car window screens not being able to be freely raised and lowered, resulting in poor practicality, and the need for frequent disassembly and reassembly of the screen when switching between in-use and out-of-use states, leading to reduced screen lifespan and cumbersome operation, this invention provides a car window and screen control lifting device.

[0006] This invention is achieved through the following technical solution:

[0007] A car window and screen control lifting device includes a servo motor and a window lifting assembly and a screen lifting assembly for controlling the window and screen respectively. The window lifting assembly and screen lifting assembly include a screen lifting gear plate and a window lifting gear plate coaxially mounted. It also includes a shift gear mechanism and a knob mechanism capable of controlling the axial movement of the shift gear mechanism. The shift gear mechanism includes a shift gear shaft driven by the servo motor and a screen lifting drive gear and a window lifting drive gear mounted on the shift gear shaft. By driving the shift gear mechanism to move axially through the knob mechanism, it is possible to achieve a state where the screen lifting drive gear and the screen lifting gear plate are engaged individually, a state where the window lifting drive gear and the window lifting gear plate are engaged individually, and a state where the screen lifting gear plate and the window lifting gear plate are engaged simultaneously with the screen lifting drive gear and the window lifting drive gear respectively.

[0008] A further improvement of the present invention is that a drive gear is mounted on the output shaft of the servo motor, and a driven gear that meshes with the drive gear is mounted on the shift gear shaft.

[0009] A further improvement of the present invention is that the driven gear is a window lifter drive gear.

[0010] A further improvement of the present invention includes that the thicknesses of the screen window lift drive gear and the window lift drive gear are respectively times the thicknesses of the screen window lift tooth plate and the window lift tooth plate, and the screen window lift tooth plate and the window lift tooth plate have the same thickness; when the screen window lift tooth plate and the window lift tooth plate are simultaneously engaged with the screen window lift drive gear and the window lift drive gear, respectively, the screen window lift tooth plate engages with the side of the screen window lift drive gear away from the window lift drive gear, and the window lift tooth plate engages with the side of the window lift drive gear away from the screen window lift drive gear; when the screen window lift drive gear and the screen window lift tooth plate are engaged individually, the screen window lift tooth plate engages with the side of the screen window lift drive gear close to the window lift drive gear; when the window lift drive gear and the window lift tooth plate are engaged individually, the window lift tooth plate engages with the side of the window lift drive gear close to the screen window lift drive gear.

[0011] A further improvement of the present invention is that the knob mechanism includes a knob disk positioned and installed on the interior panel of the door, a knob screw that rotates and is axially limited with the knob disk, and a nut that is screwed to the knob screw and can move axially. A nut limiting block is provided on the side of the nut away from the knob disk, and a shift limiting block that can engage with the nut limiting block is provided on the shift gear shaft.

[0012] A further improvement of the present invention is that a knob is provided at the end of the knob screw away from the nut.

[0013] A further improvement of the present invention is that the knob is provided with an arc-shaped groove, and the knob is provided with a slide rod that slides in conjunction with the groove.

[0014] A further improvement of the present invention is that a limit block can be detachably connected and installed at the end of the slide bar near the nut.

[0015] A further improvement of the present invention is that the outer ring of the knob is provided with anti-slip protrusions.

[0016] A further improvement of the present invention is that both the glass lifting assembly and the screen window lifting assembly adopt a cross-arm lifting structure.

[0017] As can be seen from the above technical solutions, the beneficial effects of the present invention are:

[0018] The rotary mechanism drives the shift gear mechanism to move axially (inwards and outwards), enabling individual engagement of the screen window lift drive gear and the screen window lift gear plate, thus achieving independent lifting and lowering of the glass lifting assembly (glass) by the servo motor; it can also achieve individual engagement of the glass lift drive gear and the screen window lift gear plate, thus achieving independent lifting and lowering of the screen window lifting assembly (screen) by the servo motor; or it can achieve simultaneous engagement of the glass lift gear and the screen lift drive gear, thus achieving synchronous lifting and lowering of both the glass and screen window components by the servo motor. This allows for flexible and convenient lifting and lowering adjustment of the screen and glass, offering good practicality and eliminating the need for frequent disassembly and assembly of the screen, ensuring its lifespan. The overall structure is simple, easy to use, and highly practical. Attached Figure Description

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] like Figure 1-7As shown, an optional embodiment of the present invention discloses an automotive window and screen control lifting device, including a servo motor 5 positioned and installed in the door assembly, and a window lifting assembly and a screen lifting assembly for controlling the window and screen respectively. The window lifting assembly and the screen lifting assembly are arranged in parallel and each includes a screen lifting gear plate 3 and a window lifting gear plate 4 coaxially mounted. Both the screen lifting gear plate 3 and the window lifting gear plate 4 are sector gear structures with transmission teeth on their arc edges, and the window lifting gear plate 4 is located outside the screen lifting gear plate 3. The automotive window and screen control lifting device also includes a shift gear mechanism 2 and a knob mechanism 1 capable of controlling the axial (inward and outward) movement of the shift gear mechanism 2. The shift gear mechanism 2 includes a shift gear shaft 203 (the shift gear shaft 203 can be guided to move axially inward and outward through the door assembly) and a screen lifting gear mounted on the shift gear shaft 203. The system includes a screen lifter drive gear 202 and a window lifter drive gear 204. A knob mechanism 1 drives a shift gear mechanism 2 to move axially (inwards and outwards). This allows for individual engagement between the screen lifter drive gear 202 and the screen lifter toothed plate 3, enabling the servo motor 5 to independently lift the glass component (glass). Alternatively, it can achieve individual engagement between the glass lifter drive gear 204 and the screen lifter toothed plate 4, and the screen lifter toothed plate 3, again enabling the servo motor 5 to independently lift the screen component (screen). Furthermore, it can simultaneously engage the glass lifter toothed plate 4 with both the screen lifter drive gear 202 and the screen lifter drive gear 204, achieving synchronous lifting of both components. This allows for flexible and convenient adjustment of the screen and glass, offering excellent practicality and eliminating the need for frequent screen disassembly and assembly, thus extending the screen's lifespan. The overall structure is simple, easy to use, and highly practical.

[0030] The screen window lifting assembly includes a screen window frame that can position the edges of the screen window, facilitating the overall lifting and lowering of the screen window and achieving flexibility and reliability in its use.

[0031] The servo motor 5 has a drive gear mounted on its output shaft, and the shift gear shaft 203 has a driven gear that meshes with the drive gear. The drive gear on the servo motor 5 drives the driven gear, which in turn drives the shift gear shaft 203, the screen window lift drive gear 202, and the glass lift drive gear 204 to rotate, thereby enabling flexible and convenient lifting and lowering adjustment of the screen and glass (individual adjustment of the screen and glass, or synchronous adjustment of the screen and glass).

[0032] Another optional embodiment of the present invention discloses an automotive window and screen control lifting device, including a servo motor 5 positioned and installed within a door assembly, and a window lifting assembly and a screen lifting assembly for controlling the window and screen respectively. The window lifting assembly and the screen lifting assembly are arranged in parallel and each includes a screen lifting gear plate 3 and a window lifting gear plate 4 coaxially mounted. Both the screen lifting gear plate 3 and the window lifting gear plate 4 are sector gear structures with transmission teeth on their arc-shaped edges, and the window lifting gear plate 4 is located outside the screen lifting gear plate 3. The automotive window and screen control lifting device also includes a shift gear. The mechanism includes mechanism 2 and a knob mechanism 1 capable of controlling the axial (inner and outer) movement of the shift gear mechanism 2. The shift gear mechanism 2 includes a shift gear shaft 203 (which can be axially guided by the door assembly) connected to the servo motor 5, and a screen window regulator drive gear 202 and a window regulator drive gear 204 mounted on the shift gear shaft 203. The driven gear is the window regulator drive gear 204, meaning that the driven gear and the window regulator drive gear 204 are combined into one gear for meshing with the drive gear and the window regulator toothed plate 4, which can reduce design costs and overall weight. The thickness of the screen window regulator drive gear 202 and the window regulator drive gear 204 are twice the thickness of the screen window regulator toothed plate 3 and the window regulator toothed plate 4, respectively, and the screen window regulator toothed plate 3 and the window regulator toothed plate 4 have the same thickness. The width of the drive gear is three times the width of the window regulator drive gear 204. When the screen window regulator toothed plate 3 and the window regulator toothed plate 4 are simultaneously engaged with the screen window regulator drive gear 202 and the window regulator drive gear 204, respectively, the screen window regulator toothed plate 3 is engaged with the inner half of the screen window regulator drive gear 202, and the window regulator toothed plate 4 is engaged with the outer half of the window regulator drive gear 204, while the window regulator drive gear 204 is engaged with the middle part of the drive gear. When the screen window regulator drive gear 202 and the screen window regulator toothed plate 3 are engaged individually, the screen window regulator toothed plate 3 is engaged with the outer half of the screen window regulator drive gear 202, and the window regulator drive gear 204 is engaged with the middle part of the drive gear. Gear 204 does not mesh with the window regulator gear plate 4. The window regulator drive gear 204 is located inside the window regulator gear plate 4 and meshes internally with the drive gear. When the window regulator drive gear 204 and the window regulator gear plate 4 are engaged alone, the inner half of the window regulator gear plate 4 meshes with the inner half of the window regulator drive gear 204. The screen window regulator gear plate 3 and the screen window regulator drive gear 202 do not mesh. The screen window regulator drive gear 202 is located outside the screen window regulator gear plate 3, and the window regulator drive gear 204 meshes externally with the drive gear. By controlling the axial movement of the shift gear mechanism 2, individual lifting and lowering operations of the screen and glass, as well as synchronous lifting and lowering operations of the screen and glass, can be achieved, realizing flexibility and convenience in use.

[0033] The knob mechanism 1 includes a knob disk 102 positioned and mounted on the door trim panel, a knob screw 103 that rotatably engages with and axially limits the knob disk 102, and a nut 104 screwed onto and axially movable to the knob screw 103. A nut limiting block 105 is provided on the outer side of the nut 104, and a shift limiting block 201 that engages with the nut limiting block 105 is provided on the shift gear shaft 203. The shift limiting block 201 includes two limiting plates positioned and mounted on the shift gear shaft 203. The nut limiting block 105 is fork-shaped and positioned between the two limiting plates, engaging with the shift gear shaft 203. The axial movement of the nut 104 is achieved by rotating the knob screw 103, and the nut limit block 105 engages with the shift limit block 201, which enables the transmission of axial push and pull force to the shift gear mechanism 2, thereby achieving flexible axial movement of the shift gear mechanism 2. This allows for individual lifting and lowering operations of the screen and glass, as well as synchronous lifting and lowering operations of the screen and glass, thus achieving flexibility and convenience in use.

[0034] The knob 101 is located at the inner end of the knob screw 103, and the outer ring of the knob 101 has anti-slip protrusions. The knob 101 with anti-slip protrusions makes it easy to rotate the knob screw 103, thereby enabling flexible switching between various states.

[0035] The knob disk 102 has an arc-shaped sliding groove, and the knob 101 has a sliding rod that slides in conjunction with the sliding groove. A limit block is detachably connected to the outer end of the sliding rod. The sliding rod and the sliding groove guide and limit the rotation of the knob 101 (forward and reverse extreme positions). When the knob 101 is rotated to the left end of the sliding groove, the screen window is raised and lowered independently. When the knob 101 is rotated to the right end of the sliding groove, the glass is raised and lowered independently. When the knob is rotated to the middle position of the sliding groove, the screen window and the glass are raised and lowered synchronously. A synchronous control indicator is set in the middle of the sliding groove for easy identification and operation. The limit block limits the axial movement of the knob disk 102 on the knob 101 and the knob screw 103, ensuring that they only rotate and do not undergo axial displacement.

[0036] Both the glass lifting assembly and the screen window lifting assembly adopt a cross-arm lifting structure. The cross-arm glass lifter has a larger support width, smoother movement, and a wider range of applications.

[0037] This automotive window and screen control device, through a knob mechanism 1 driving a shift gear mechanism 2 to move axially (inward and outward), can achieve the following states: the screen lift drive gear 202 can be individually engaged with the screen lift gear plate 3, enabling the servo motor 5 to independently drive the glass lifting assembly (glass); the window lift drive gear 204 can be individually engaged with the window lift gear plate 4 and the screen lift gear plate 3, enabling the servo motor 5 to independently drive the screen lifting assembly (screen); the window lift gear plate 4 can be simultaneously engaged with both the screen lift drive gear 202 and the window lift drive gear 204, enabling the servo motor 5 to synchronously drive both the glass and screen lifting assemblies (screen). This allows for flexible and convenient adjustment of the screen and glass, offering good practicality and eliminating the need for frequent screen disassembly and assembly, thus ensuring the screen's lifespan. The overall structure is simple, easy to use, and highly practical.
