Description

Technical Field

[0001] This utility model relates to the field of automotive window technology, and in particular to an anti-pinch lifting device for automotive window glass. Background Technology

[0002] Car windows are an important part of the car body. They not only provide passengers with a view and ventilation, but also have an important impact on the vehicle's safety, comfort, and aesthetics. They also provide drivers and passengers with a view inside and outside the vehicle, making it easier for drivers to observe traffic conditions, pedestrians, and the surrounding environment. Good visibility is crucial for driving safety. The transparency, shape, and position of the car window glass all directly affect the range and clarity of the field of vision.

[0003] Currently, car windows are raised and lowered via electric lifting mechanisms, which consist of a motor, reducer, wire or toothed belt drive, guide rail, and slider. The motor transmits power to the drive unit through the reducer, causing the window to move up and down along the guide rail. The advantages of electric lifting mechanisms are strong power, ease of operation, and the ability to perform multiple functions through control circuits. However, if a hand or arm is placed on top of the window during the window raising or lowering process and the window button is accidentally pressed, the window may pinch the hand or arm. The existing solution is to add an anti-pinch device for protection. However, anti-pinch devices can misjudge situations, such as misinterpreting small foreign objects on the window track as obstacles and triggering the anti-pinch function. During vehicle movement, road bumps can cause foreign objects in the window track to move, triggering the anti-pinch function and preventing the window from closing properly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-pinch lifting device for automobile windows, which aims to improve the problem in the prior art where, during vehicle operation, road bumps cause foreign objects in the window track to move, triggering the anti-pinch function and preventing the window from closing properly.

[0007] The disassembly mechanism includes two limiting shells. The adjacent sides of the two limiting shells are respectively fixedly connected to the left and right sides of the rear outer shell. The inner bottom wall of the limiting shell is rotatably connected to a threaded rod. The outer wall of the threaded rod is threadedly connected to a displacement plate. The top end of the threaded rod is fixedly connected to a knob. The left and right sides of the front outer shell are both connected to protective shells. One side of the inner wall of the protective shell is fixedly connected to a locking shell. The top wall of the locking shell has a locking groove. The bottom of the displacement plate engages with the locking groove.

[0008] As a further description of the above technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an anti-pinch lifting device for automotive windows, comprising two housings 1 and two multi-hole nozzles 9. A miniature fan 3 is fixedly connected to the front left end of the front housing 1. Activation of the miniature fan 3 causes it to draw air through an extraction housing 5. An extraction pipe 4 is connected to the top right side of the miniature fan 3, and the right end of the extraction pipe 4 is connected to the extraction housing 5. The connection between the miniature fan 3 and the extraction housing 5 is achieved through the extraction pipe 4. Filter plates 6 are connected to the upper and lower front ends of the extraction housing 5, thereby filtering out larger particles in the air. The particles are filtered by the filter plate 6. An adsorption sponge plate 7 is fixedly installed on the left side of the inner wall of the extraction shell 5. Under the adsorption of the adsorption sponge plate 7, the water vapor in the air is adsorbed. The bottom right side of the micro fan 3 is connected to the conveying pipe 8. The rear end of the conveying pipe 8 is connected to the front side of the multi-hole nozzle 9. Thus, the multi-hole nozzle 9 completes the conveying of airflow. The two multi-hole nozzles 9 are fixedly connected to the bottom side of the corresponding shell 1 on opposite sides. The bottom walls of the two multi-hole nozzles 9 are connected by the connecting pipe 11, thus the connecting pipe 11 achieves the effect of installation and disassembly.

[0032] Sponge filter plates 10 are fixedly connected to the middle of adjacent sides of the two outer shells 1. The sponge filter plates 10 block particles. An inclined groove 12 is opened in the middle of one side of the outer shell 1. A glass plate 18 is arranged between the two adjacent outer shells 1. Anti-pinch lifting devices 19 are fixedly installed on the left and right sides of the bottom of the glass plate 18. The anti-pinch lifting devices 19 drive and prevent the glass plate 18. The left and right sides of the rear outer shell 1 are provided with disassembly mechanisms 2. The disassembly mechanisms 2 are used to improve the disassembly efficiency of the device. A rubber ring 17 is fixedly installed on the right end of the outer wall of the extraction tube 4. The rubber ring 17 protects the right end connection of the extraction tube 4. The outer wall of the rubber ring 17 is fixedly connected to the left side of the extraction shell 5. Connecting seats 15 are fixedly connected to the left and right sides of the front outer shell 1. An installation groove 16 is opened on the front side of the connecting seat 15. The device is completed and fixed by the connecting seat 15 and the installation groove 16.

[0033] Reference Figure 1 and Figure 5 The disassembly mechanism 2 includes two limiting shells 201. The adjacent sides of the two limiting shells 201 are fixedly connected to the left and right sides of the rear outer shell 1, respectively. A threaded rod 202 is rotatably connected to the inner bottom wall of the limiting shell 201. Rotation of the threaded rod 202 drives the displacement plate 203. The outer wall of the threaded rod 202 is threadedly connected to the displacement plate 203, allowing the displacement plate 203 to rise and fall. A knob 204 is fixedly connected to the top of the threaded rod 202. Protective shells 206 are connected to both the left and right sides of the front outer shell 1, allowing the locking shell 2 to be locked. For the fixing of 07, a locking shell 207 is fixedly connected to one side of the inner wall of the protective shell 206. The top wall of the locking shell 207 is provided with a locking groove 208, which is used to lock and separate from the displacement plate 203, thereby achieving the purpose of locking or disassembling the two shells 1. The bottom of the displacement plate 203 is engaged with the locking groove 208. The disassembly mechanism 2 also includes multiple protrusions 205. The fixing of multiple protrusions 205 improves the anti-slip effect of the knob 204. One side of each of the multiple protrusions 205 is fixedly connected to the outer wall of the corresponding knob 204.

[0034] Reference Figure 1 , Figure 2 and Figure 4A control switch 14 is fixedly connected to the top right side of the front outer shell 1. The control switch 14 is electrically connected to the micro fan 3 and the two anti-pinch lifting devices 19. The control switch 14, which is electrically connected to the micro fan 3 and the two anti-pinch lifting devices 19, enables the control switch 14 to turn the equipment on and off. Multiple arc-shaped grooves 13 are opened on the top of adjacent sides of the two outer shells 1. The opening of multiple arc-shaped grooves 13 increases the airflow delivery area. The multiple arc-shaped grooves 13 are all equally spaced. The top wall of the glass plate 18 is designed to be smooth, thereby improving the pressure resistance of the glass plate 18. The rear side of the extraction shell 5 is fixedly connected to the middle of the front side of the front outer shell 1.

[0035] Working principle: When in use, the glass plate 18 is driven and anti-pinch function is completed by the start of the anti-pinch lifting device 19. Then, the micro fan 3 is started, which draws air through the extraction shell 5. The air passes through the filter plate 6 to filter out larger particles and impurities, and is dried by the adsorption sponge plate 7. The filtered and dried air is then transported through the delivery pipe 8. Under the spray of the multi-hole nozzle 9, foreign objects in the window track are output, achieving the effect of blowing away and cleaning foreign objects. At the same time, the sponge filter plate 10 effectively reduces the possibility of foreign objects falling and interfering with the anti-pinch lifting device 19.

[0036] Furthermore, by rotating the knob 204, the threaded rod 202 is rotated. Simultaneously, the rotation of the threaded rod 202 drives the displacement plate 203 to rise and fall under the restriction of the rotation of the limiting shell 201. This causes the bottom of the displacement plate 203 to separate or engage with the locking groove 208 inside the locking shell 207, pulling one side of the outer shell 1 to achieve the purpose of connecting and disassembling the two outer shells 1, thereby improving the efficiency of internal maintenance and cleaning of the device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
