Description

Technical Field

[0001] The utility model relates to the technical field of window ripple anti-pinch, in particular to a four-door window ripple anti-pinch structure. Background Technique

[0002] At present, the anti-pinch of electric sunroofs and doors and windows is mainly based on the following two schemes: the Hall sensor scheme and the motor current ripple scheme. In the commutation process of a brushed DC motor, current ripple will be generated. The number of ripples is proportional to the motor speed and the number of commutator segments. Therefore, if the current ripple can be extracted, the position information of the window movement can be obtained. At the same time, when an obstacle is encountered during the movement of the door and window, the current will increase, and the anti-pinch judgment can be made according to the magnitude of the current. This is the principle of the anti-pinch scheme based on ripple. Compared with the Hall anti-pinch scheme, the scheme based on current ripple does not require a dedicated Hall sensor, eliminating the cost of installing magnetic rings, Hall sensors and wiring harnesses. In addition, a single controller can be used to control four doors simultaneously, saving the controller cost and improving the vehicle integration. The anti-pinch scheme based on motor ripple can greatly reduce the cost and is the future development trend of electric door and window anti-pinch. When the window body in the ripple anti-pinch structure is damaged, it needs to be replaced. In the prior art, when replacing the window body, external tools are mostly required, and the steps are relatively cumbersome. Content of the Utility Model

A shell is fixedly connected to the top of the ripple anti-pinch mechanism main body. A threaded component and a plurality of groups of limiting rods are connected between the side walls at the front and rear ends of the inner cavity of the shell. The threaded component is symmetrically and threadedly connected with long plates, and the long plates are slidably arranged on the limiting rods. A plurality of groups of clamping plates are symmetrically and equally angularly fixedly connected to the tops of the two long plates, and the window main body is located between a plurality of groups of symmetrically arranged clamping plates. A toothed plate is fixedly connected to the threaded component. Mounting plates are symmetrically and fixedly connected to the front end of the shell, and fastening components that are slidably arranged on the side walls of the mounting plates and are mutually engaged with the toothed plate are provided.

[0005] Based on the above technical features: When the window main body needs to be replaced, first, remove the outer shell of the door frame main body to expose the inner cavity of the door frame main body. Then, pull the two sets of fastening components symmetrically arranged in a direction away from the toothed plate, so that the fastening ends of the fastening components are separated from the toothed plate, thereby releasing the limit fixation of the fastening components on the toothed plate and the threaded component. Then, rotate the threaded component, and the symmetrically arranged long plates move in opposite directions along the thread direction of the threaded component. The arranged long plates drive the clamping plates to move in a direction away from the window main body, thereby releasing the fixed clamping operation of the clamping plates on the window main body. Then, the window main body can be removed for replacement.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a four-door ripple anti-pinch structure for vehicle windows through improvement. The technical solution of the present utility model is as follows:

[0029] As Figures 1-6 shown, a four-door ripple anti-pinch structure for vehicle windows includes a door frame main body 1, a ripple anti-pinch mechanism main body 2 and a vehicle window main body 3. The ripple anti-pinch mechanism main body 2 is installed at the bottom of the inner cavity of the door frame main body 1. A housing 4 is fixedly connected to the top of the ripple anti-pinch mechanism main body 2. A threaded component 5 and a plurality of groups of limiting rods 6 are connected between the front and rear end side walls of the inner cavity of the housing 4. Long plates 7 are symmetrically threadedly connected to the threaded component 5, and the long plates 7 are slidably arranged on the limiting rods 6. A plurality of groups of clamping plates 8 are symmetrically and equally angled fixedly connected to the tops of the two groups of long plates 7, and the vehicle window main body 3 is located between the plurality of groups of symmetrically arranged clamping plates 8. A toothed plate 9 is fixedly connected to the threaded component 5. Mounting plates 10 are symmetrically and fixedly connected to the front end of the housing 4. A fastening component 11 that is slidably engaged with the toothed plate 9 is slidably arranged on the side wall of the mounting plate 10.

[0030] Furthermore, the fastening component 11 includes a sliding rod 111 slidably arranged on the side wall of the mounting plate 10. A round plate 112 is fixedly connected to the rod body of the sliding rod 111. A spring 113 is wound around the rod body of the sliding rod 111, and the spring 113 is connected between the round plate 112 and the mounting plate 10. A toothed block 114 that is engaged with the toothed plate 9 is fixedly connected to the side of the sliding rod 111 close to the toothed plate 9. When the vehicle window main body 3 needs to be replaced, first, the outer shell of the door frame main body 1 is disassembled to expose the inner cavity of the door frame main body 1. Then, the two groups of symmetrically arranged sliding rods 111 are pulled to move away from the toothed plate 9, and the arranged sliding rods 111 drive the toothed block 114 to move.

[0031] Among them, a pull ring 12 is fixedly connected to the side of the sliding rod 111 away from the toothed plate 9. The arranged pull ring 12 facilitates pulling the sliding rod 111 to slide. The sliding rod 111 is made of stainless steel material, which extends the service life of the sliding rod 111.

[0032] Further, the threaded assembly 5 includes a bidirectional lead screw 51 rotatably connected between the front and rear end side walls of the inner cavity of the housing 4. One side of the bidirectional lead screw 51 located outside the housing 4 is fixedly connected with a wrench 52. The tooth block 114 is separated from the toothed plate 9, thereby releasing the limit fixation of the tooth block 114 on the toothed plate 9 and the bidirectional lead screw 51. During this process, the provided spring 113 is compressed under force. Subsequently, the worker rotates the wrench 52, and the provided wrench 52 drives the bidirectional lead screw 51 to rotate. The symmetrically arranged long plates 7 move away from each other along the thread direction of the bidirectional lead screw 51. The provided long plates 7 drive the clamping plates 8 to move away from the window body 3, thereby releasing the fixed clamping operation of the clamping plates 8 on the window body 3. Subsequently, the window body 3 can be removed and replaced.

[0033] In addition, anti-slip pads are provided on the sides of the clamping plates 8 close to the window body 3, and the provided anti-slip pads increase the friction between the clamping plates 8 and the window body 3.

[0034] Working principle: When the window body 3 needs to be replaced, first, the outer shell of the door frame body 1 is disassembled to expose the inner cavity of the door frame body 1. Subsequently, the two groups of symmetrically arranged sliding rods 111 are pulled to move away from the toothed plate 9. The provided sliding rods 111 drive the tooth block 114 to move, causing the tooth block 114 to be separated from the toothed plate 9, thereby releasing the limit fixation of the tooth block 114 on the toothed plate 9 and the bidirectional lead screw 51. During this process, the provided spring 113 is compressed under force. Subsequently, the worker rotates the wrench 52, and the provided wrench 52 drives the bidirectional lead screw 51 to rotate. The symmetrically arranged long plates 7 move away from each other along the thread direction of the bidirectional lead screw 51. The provided long plates 7 drive the clamping plates 8 to move away from the window body 3, thereby releasing the fixed clamping operation of the clamping plates 8 on the window body 3. Subsequently, the window body 3 can be removed and replaced. When the device in this application replaces the window body 3, external tools are not required, and the steps are relatively simple. This action improves the convenience to a certain extent when replacing the window body 3.
