Abstract
Description
Technical Field
[0001] This application relates to the field of window regulators, and particularly to a window regulator with an anti-jerk mechanism, a car door, and an automobile. Background Technology
[0002] Currently, in rainy or snowy weather, users may experience a slight shaking of the car window when raising or lowering it, especially when lowering the window. This jerking sensation arises because rain and snow can cause raindrops to enter the glass guide channel, or snow to fall into the guide channel and melt into water over time. This causes fluctuations in the sliding resistance of the door glass guide channel. In a cable-driven window regulator, when the glass needs to be lowered, the user operates a switch to trigger a command, powering the regulator motor. The motor's output shaft rotates, driving a steel cable. The end of the steel cable compresses a lower spring, and the regulator slider connected to the lower spring also moves downwards. Since the door glass is fixed to the regulator slider, it moves downwards with the slider, achieving the glass descent. The lower spring acts as a shock absorber. However, under normal circumstances, the direction of the glass's gravity and the motor's driving force is downwards throughout the descent. Since the glass's gravity alone is sufficient to maintain the system's mechanical balance, the motor's driving force is relatively small. When water enters the door glass guide channel, the sliding resistance fluctuates, causing instability in the compression force of the lower spring and fluctuations in the lower spring's contraction amplitude. When the lower spring is pressed down, the fluctuation in the contraction amplitude of the lower spring is fed back to the wire rope plug. This causes the wire rope plug and the slider of the lifting device to move asynchronously when the glass descends, resulting in a jerky feeling when the glass descends. Summary of the Invention
[0003] This application provides a window regulator, a car door, and a car with an anti-jerk mechanism to solve the problem in the related art where a jerky sensation occurs when the glass descends when water enters the glass guide channel of the car door.
[0004] In a first aspect, embodiments of this application provide a window regulator with an anti-jerk mechanism, comprising:
[0005] A lifting slider is provided, a steel wire rope is connected to the lifting slider, a steel wire rope plug is connected to the steel wire rope, and a lower spring for shock absorption is provided between the steel wire rope plug and the lifting slider.
[0006] An anti-slipping mechanism is connected to the wire rope plug to ensure that the wire rope plug and the lifting device slider move synchronously.
[0007] In some embodiments, the anti-stuttering mechanism includes a lifting plate fixed to the top of the wire rope plug, an electromagnet fixedly disposed at the bottom of the lifting plate, and metal blocks vertically spaced at the bottom of the electromagnet. The electromagnet is used to drive the lifting plate to move toward the metal blocks.
[0008] In some embodiments, the sidewall of the lifting plate is provided with a slide rail along the moving direction of the lifting plate.
[0009] In some embodiments, the vertical distance between the electromagnet and the metal block is the same as the compression distance of the lower spring.
[0010] In some embodiments, the lifting plate is an elastic metal sheet.
[0011] In some embodiments, the diameter of the end of the wire rope plug is larger than the diameter of the lower spring.
[0012] In some embodiments, the wire rope plug has a "T" shaped structure, one end of the lower spring touches the wire rope plug, and the wire rope plug extends into the lower spring.
[0013] In some embodiments, both the electromagnet and the metal block are cylindrical structures, and both the end edge of the electromagnet near the end edge of the metal block and the end edge of the metal block near the end edge of the electromagnet are provided with arc-shaped chamfers.
[0014] Secondly, embodiments of this application provide a car door, including the aforementioned window regulator with an anti-jerk mechanism.
[0015] Thirdly, embodiments of this application provide an automobile, including the aforementioned door.
[0016] The beneficial effects of the technical solution provided in this application include:
[0017] This application provides a window regulator, a car door, and a car with an anti-jerk mechanism. The window regulator with the anti-jerk mechanism includes a regulator slider and an anti-jerk mechanism. A steel wire rope is connected to the regulator slider, and a steel wire rope plug is connected to the steel wire rope. A lower spring for shock absorption is provided between the steel wire rope plug and the regulator slider. The anti-jerk mechanism is connected to the steel wire rope plug and is used to keep the steel wire rope plug and the regulator slider moving synchronously.
[0018] In a cable-driven window regulator, when the glass needs to be lowered, the user activates a switch to power the regulator motor. The motor drives a steel cable, which in turn moves the regulator slider to lower the glass. During this process, the steel cable pushes down a spring via a cable plug to absorb shock. However, normally, the weight of the glass and the driving force of the motor are both downwards during the descent. Since the weight of the glass is generally sufficient to maintain the system's mechanical balance, the motor's driving force during descent is relatively small. When water enters the door glass guide channel, the sliding resistance within the channel fluctuates, causing fluctuations in the compression force of the lower spring and its contraction amplitude. When the cable plug presses down on the lower spring, these fluctuations in spring contraction amplitude are fed back to the cable plug, causing a missynchronization between the cable plug and the regulator slider during descent, resulting in a jerky or abrupt drop in the glass's descent. Because of the anti-jerk mechanism connected to the wire rope plug, the anti-jerk mechanism can keep the wire rope plug and the lifting slider moving synchronously. Even if water enters the door glass guide channel and the sliding resistance of the glass fluctuates when it descends, causing fluctuations in the contraction amplitude of the lower spring, the anti-jerk mechanism can still ensure that the wire rope plug and the lifting slider move synchronously, preventing the glass from jerking when it descends.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] This application provides a window regulator, a car door, and a car with an anti-jerk mechanism, which can solve the problem in the related art where a jerky feeling occurs when the glass descends when water enters the glass guide channel of the car door.
[0026] See Figure 1 and Figure 2 As shown, in one aspect, this application provides a glass lifter with an anti-jerk mechanism, including a lifter slider and an anti-jerk mechanism. A steel wire rope 6 is connected to the lifter slider, and a steel wire rope plug 4 is connected to the steel wire rope 6. A lower spring 5 for shock absorption is provided between the steel wire rope plug 4 and the lifter slider. The anti-jerk mechanism is connected to the steel wire rope plug 4 and is used to keep the steel wire rope plug 4 and the lifter slider moving synchronously.
[0027] In a rope-driven window regulator, when the glass needs to be lowered, the user activates a switch to power the regulator motor. The motor drives the steel cable 6, causing the regulator slider to lower the glass. During this process, the steel cable 6 drives the steel cable plug 4 to press down the lower spring 5 for shock absorption. However, normally, the direction of the glass's gravity and the motor's driving force is downward throughout the descent. Since the glass's gravity alone is sufficient to maintain the system's mechanical balance, the motor's driving force during descent is relatively small. When water enters the door glass guide channel, the sliding resistance within the channel fluctuates, causing fluctuations in the compression force of the lower spring 5 and its contraction amplitude. When the steel cable plug 4 presses down on the lower spring 5, these fluctuations in contraction amplitude are fed back to the steel cable plug 4, causing a missynchronization between the steel cable plug 4 and the regulator slider during descent, resulting in a jerky feeling during the glass's descent. Because of the anti-jerk mechanism connected to the wire rope plug 4, the anti-jerk mechanism can keep the wire rope plug 4 and the window regulator slider moving synchronously. Even if water enters the door glass guide channel and the sliding resistance of the glass fluctuates when it descends, causing the contraction amplitude of the lower spring 5 to fluctuate, the anti-jerk mechanism can still ensure that the wire rope plug 4 and the window regulator slider move synchronously, preventing the glass from jerking when it descends.
[0028] In some alternative embodiments, the anti-stuttering mechanism includes a lifting plate 1 fixed to the top of the wire rope plug 4, an electromagnet 2 fixedly disposed at the bottom of the lifting plate 1, and metal blocks 3 vertically spaced at the bottom of the electromagnet 2. The electromagnet 2 is used to drive the lifting plate 1 to move toward the metal blocks 3.
[0029] When power is supplied to the window regulator motor, the motor drives the steel cable 6, causing the window regulator slider to lower the glass. At this time, the steel cable 6 drives the steel cable plug 4 to press down the lower spring 5 for shock absorption. However, normally, the direction of the glass's gravity and the motor's driving force is downward throughout the descent. Since the glass's gravity alone is sufficient to maintain the system's mechanical balance, the motor's driving force during glass descent is relatively small. When water enters the door glass guide channel, the sliding resistance within the channel fluctuates, causing fluctuations in the compression force of the lower spring 5 and its contraction amplitude. When the steel cable plug 4 presses down on the lower spring 5, these fluctuations in the spring 5's contraction amplitude are fed back to the steel cable plug 4, causing a missynchronization between the steel cable plug 4 and the window regulator slider during descent, resulting in a jerky feeling during the glass's descent. Therefore, in actual use, the glass drops with a jerky feeling. The root cause is that the force compressing the lower spring 5 fluctuates, causing the contraction amplitude of the lower spring 5 to fluctuate.
[0030] The anti-jerk mechanism includes a lifting plate 1 fixed to the top of the wire rope plug 4, an electromagnet 2 fixedly installed at the bottom of the lifting plate 1, and metal blocks 3 vertically spaced at the bottom of the electromagnet 2. The electromagnet 2 is used to drive the lifting plate 1 to move towards the metal blocks 3. In actual use, if water enters the door glass guide channel, this mechanism is used to prevent the glass from jerking during descent. The anti-jerk mechanism can be activated. Specifically, after the electromagnet 2 is energized, it generates magnetic force. Metal blocks 3 are vertically spaced at the bottom of the electromagnet 2. After the electromagnet 2 generates magnetic force, it will attract the metal blocks 3. The metal blocks 3 are fixed to the fixed seat inside the glass lifter. The attraction between the electromagnet 2 and the metal blocks 3 will cause the electromagnet 2 to move towards the metal blocks 3. Since the electromagnet 2 is fixed to the lifting plate 1, the movement of the electromagnet 2 will drive the lifting plate 1 to move downward. The lifting plate 1 is fixed to the top of the wire rope plug 4, which in turn causes the wire rope plug 4 to move downward. The bottom of the wire rope plug 4 is provided with a lower spring 5. Therefore, under the action of the wire rope plug 4, the lower spring 5 can be pressed down and retract normally.
[0031] This anti-jerk mechanism ensures the normal contraction of the lower spring 5. Even if water enters the door glass guide channel and the sliding resistance in the door glass guide channel fluctuates, the compression force of the lower spring 5 will not fluctuate, thus avoiding fluctuations in the contraction amplitude of the lower spring 5. The movement of the wire rope plug 4 will also not be interfered with by the lower spring 5. The wire rope plug 4 and the window regulator slider maintain synchronous movement, preventing a jerky feeling when the glass descends when water enters the door glass guide channel.
[0032] Once the glass has descended, the power supply to electromagnet 2 is cut off, the attraction between electromagnet 2 and metal block 3 disappears, and the normal glass-raising operation can then proceed.
[0033] When the glass needs to be raised, the motor drives the steel cable 6 to move, so that the slider of the lifter can lift the glass. At this time, the driving force of the motor is relatively large because it needs to overcome the weight of the glass. When water enters the door glass guide channel, the fluctuation of the sliding resistance in the door glass guide channel has no significant impact on the glass's rising state, and the glass will not have a jerking sensation.
[0034] In some optional embodiments, the side wall of the lifting plate 1 is provided with a slide rail along the moving direction of the lifting plate 1. The slide rail ensures the normal lifting and lowering of the lifting plate 1, and facilitates the lifting plate 1 to move downward and rise and reset under the drive of the electromagnet 2.
[0035] In some alternative embodiments, the vertical distance between the electromagnet 2 and the metal block 3 is the same as the compression distance of the lower spring 5. This ensures the reliability of the compression of the lower spring 5.
[0036] In some alternative embodiments, the lifting plate 1 is an elastic metal sheet, which enables the lifting plate 1 to have a certain shock absorption effect and buffering when it drives the wire rope plug 4 to press down the spring 5.
[0037] In some alternative embodiments, the diameter of the end of the wire rope plug 4 is larger than the diameter of the lower spring 5. The wire rope plug 4 has a "T"-shaped structure, with one end of the lower spring 5 abutting against the wire rope plug 4, and part of the wire rope plug 4 extending into the lower spring 5. This ensures the reliability of the wire rope plug 4 abutting against the lower spring 5.
[0038] In some optional embodiments, both the electromagnet 2 and the metal block 3 are cylindrical structures, with rounded chamfers at the end edges of both the electromagnet 2 and the metal block 3 near the end edges of the electromagnet 2. The cylindrical structure of both the electromagnet 2 and the metal block 3 reduces the space occupied by them, improving the rationality of the structural arrangement. Furthermore, the rounded chamfers at the end edges of both the electromagnet 2 and the metal block 3 near the end edges of the electromagnet 2 prevent mutual rubbing when they come into contact, thus avoiding damage to the components.
[0039] In summary, the anti-jerk mechanism includes a lifting plate 1 fixed to the top of the wire rope plug 4, an electromagnet 2 fixedly mounted at the bottom of the lifting plate 1, and metal blocks 3 vertically spaced at the bottom of the electromagnet 2. The electromagnet 2 is used to drive the lifting plate 1 to move towards the metal blocks 3. In actual use, if water enters the door glass guide channel, this mechanism is used to prevent the glass from jerking during descent. The anti-jerk mechanism can be activated. Specifically, after the electromagnet 2 is energized, it generates magnetic force. Metal blocks 3 are vertically spaced at the bottom of the electromagnet 2. After the electromagnet 2 generates magnetic force, it will attract the metal blocks 3. The metal blocks 3 are fixed to the fixed seat inside the glass lifter. The attraction between the electromagnet 2 and the metal blocks 3 will cause the electromagnet 2 to move towards the metal blocks 3. Since the electromagnet 2 is fixed to the lifting plate 1, the movement of the electromagnet 2 will drive the lifting plate 1 to move downward. The lifting plate 1 is fixed to the top of the wire rope plug 4, which in turn causes the wire rope plug 4 to move downward. The bottom of the wire rope plug 4 is provided with a lower spring 5. Therefore, under the action of the wire rope plug 4, the lower spring 5 can be pressed down and retract normally.
[0040] This anti-jerk mechanism ensures the normal contraction of the lower spring 5. Even if water enters the door glass guide channel and the sliding resistance within the guide channel fluctuates, the compression force on the lower spring 5 will not fluctuate, preventing fluctuations in the contraction amplitude of the lower spring 5. Furthermore, the movement of the wire rope plug 4 will not be interfered with by the lower spring 5. The wire rope plug 4 and the window regulator slider maintain synchronized movement, preventing a jerky feeling when the glass descends when water enters the door glass guide channel. Of course, the anti-jerk mechanism can be implemented in various forms, not limited to the above embodiments.
[0041] See Figure 1 and Figure 2 As shown, in a second aspect, embodiments of this application provide a car door, including the aforementioned window regulator with an anti-jerk mechanism.
[0042] In actual use, when the window regulator motor is powered, the motor drives the steel cable 6 to move, allowing the window regulator slider to lower the glass. At this time, the steel cable 6 drives the steel cable plug 4 to press down the lower spring 5 for shock absorption. However, under normal circumstances, the direction of the glass's gravity and the motor's driving force is downward throughout the entire descent process. Since the glass's gravity alone is sufficient to maintain the system's mechanical balance, the motor's driving force during glass descent is relatively small. When water enters the door glass guide channel, the sliding resistance within the guide channel fluctuates, causing fluctuations in the compression force of the lower spring 5 and the amplitude of its contraction. When the steel cable plug 4 presses down on the lower spring 5, the fluctuations in the contraction amplitude of the lower spring 5 are fed back to the steel cable plug 4, causing the movement of the steel cable plug 4 and the window regulator slider to be asynchronous during glass descent, resulting in a jerky feeling during the glass's descent. Therefore, in actual use, the glass drops with a jerky feeling. The root cause is that the force compressing the lower spring 5 fluctuates, causing the contraction amplitude of the lower spring 5 to fluctuate.
[0043] The anti-jerk mechanism includes a lifting plate 1 fixed to the top of the wire rope plug 4, an electromagnet 2 fixedly installed at the bottom of the lifting plate 1, and metal blocks 3 vertically spaced at the bottom of the electromagnet 2. The electromagnet 2 is used to drive the lifting plate 1 to move towards the metal blocks 3. In actual use, if water enters the door glass guide channel, this mechanism is used to prevent the glass from jerking during descent. The anti-jerk mechanism can be activated. Specifically, after the electromagnet 2 is energized, it generates magnetic force. Metal blocks 3 are vertically spaced at the bottom of the electromagnet 2. After the electromagnet 2 generates magnetic force, it will attract the metal blocks 3. The metal blocks 3 are fixed to the fixed seat inside the glass lifter. The attraction between the electromagnet 2 and the metal blocks 3 will cause the electromagnet 2 to move towards the metal blocks 3. Since the electromagnet 2 is fixed to the lifting plate 1, the movement of the electromagnet 2 will drive the lifting plate 1 to move downward. The lifting plate 1 is fixed to the top of the wire rope plug 4, which in turn causes the wire rope plug 4 to move downward. The bottom of the wire rope plug 4 is provided with a lower spring 5. Therefore, under the action of the wire rope plug 4, the lower spring 5 can be pressed down and retract normally.
[0044] Because the car door includes a window regulator with an anti-jerk mechanism, the anti-jerk mechanism ensures the normal contraction of the lower spring 5. Even if water enters the door glass guide channel and the sliding resistance in the door glass guide channel fluctuates, the force compressing the lower spring 5 will not fluctuate, thus avoiding fluctuations in the contraction amplitude of the lower spring 5. The movement of the wire rope plug 4 will also not be interfered with by the lower spring 5. The wire rope plug 4 and the regulator slider maintain synchronous movement, preventing a jerky feeling when the glass descends when water enters the door glass guide channel.
