Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a window glass lifting switch. Background Technology

[0002] Currently, window regulator switches, as an important component of automotive electronic control systems, are widely used in various passenger and commercial vehicles. Most existing window regulator switches employ a button-type structure, where the button and circuit board typically trigger the window raising / lowering signal through direct contact. In this structure, the force transmission between the button and the touch switch is relatively simple. When the driver operates the switch frequently, problems such as unresponsive button feedback, trigger position misalignment, and unstable switch contact can easily occur, leading to delays or even failures in the window raising / lowering control process.

[0003] The installation methods for existing window regulator buttons are generally quite complex. Some structures rely solely on screws or single-point clips for fixation, resulting in low installation efficiency and insufficient stability. Over long-term use, the buttons are prone to loosening or shifting, affecting the driver's operating experience. Furthermore, improper matching between the button and the base can easily cause the button to wobble or misalign during operation, further reducing its overall lifespan.

[0004] Safety function buttons in existing designs often employ a simple plug-in structure, lacking reliable guiding and limiting mechanisms. This makes them prone to detachment or jamming during repeated use, affecting the timely triggering of safety functions. Furthermore, in terms of button surface design, some products fail to consider special operating environments such as wet or slippery driver hands or vehicle vibrations, leading to a risk of slippage during operation.

[0005] In summary, existing window lift switches generally suffer from problems such as unresponsive button operation, unstable installation and positioning, insufficient reliability of safety button triggering, and poor ease of operation. Utility Model Content

[0021] A second guide groove is provided on the opposite surfaces of the two limiting plates;

[0022] When installing the window lift button onto the button base, align the second guide groove with the positioning post and apply downward pressure so that the positioning post passes through the second positioning hole.

[0023] Limit seats are provided on both sides of the bottom of the button base. The limit seats are arc-shaped, and the two sides of the glass lifting button rest against the limit seats.

[0028] Furthermore, the safety button is symmetrically and fixedly connected with guide strips inside, and the guide strips are engaged in the first guide grooves opened at both ends of the base;

[0029] The safety button has limit slots at both ends, and the base has claws at both ends that extend into the limit slots.

[0030] Furthermore, the upper surface of the base is arrayed with supporting bosses, which abut against the lower surface of the circuit board component.

[0032] Furthermore, both sides of the outer shell are provided with first locking protrusions, which engage with the inner panel of the door when the outer shell is installed.

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] By setting up a circuit board component inside the housing and arranging a glass touch switch and a safety touch switch on the circuit board component, and inserting a base at the bottom of the housing for support, the problem of complex structure and inconvenient installation of existing car window lift switches is solved. This allows the circuit board component to maintain stable force during operation and improves the reliability of the overall structure.

[0035] By setting a linkage mechanism between the window lift button and the window touch switch, which consists of a steel ball and a spring, the force applied by the button can be stably transmitted to the window touch switch. This solves the problems of insensitive button feedback, trigger position offset and unstable switch contact in traditional switches, thereby achieving sensitive triggering and long-term stable use of the window lift operation.

[0036] By setting positioning posts on both sides of the button base and setting a limiting plate and a second positioning hole inside the glass lifting button, the limiting structure of the first positioning hole and the second guide groove is combined to ensure the accurate positioning and stable limiting of the glass lifting button during installation. This solves the problems of complex button assembly and easy loosening and displacement in the prior art, and improves installation efficiency and operation stability.

[0037] By setting an arc-shaped limiting seat at the bottom of the button base and setting an isolation plate between the two button bases, the glass lifting buttons are prevented from swinging laterally and interfering with each other during operation. This solves the problem of buttons easily shaking during use in the prior art, thus ensuring the stability and accuracy of operation.

[0038] By setting a pressing post, guide strip, first guide groove, and a locking structure between the safety button and the base, the safety button can maintain stable vertical linear movement during operation and avoid falling off. This solves the problems of inaccurate positioning, easy shaking, and unstable operation of existing safety buttons, and improves the reliability of safety function triggering.

[0055] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0056] Example 1:

[0057] See Figure 1-9 A vehicle window lift switch includes a housing 1 installed on the inside of a vehicle door. The housing 1 is engaged with the inner panel of the door via a first locking protrusion 11 to ensure the stability of the overall structure. A circuit board component 3 is disposed inside the lower part of the housing 1. The circuit board component 3 integrates electrical circuitry for controlling window lifting and safety protection, and can receive button operation signals and drive the window motor. A glass touch switch 31 and a safety touch switch 32 are disposed on the upper surface of the circuit board component 3. The glass touch switch 31 receives trigger signals from a window lifting button 4, and the safety touch switch 32 receives trigger signals from a safety button 5. A base 2 is inserted into the bottom of the housing 1, and the base 2 and the housing 1 are engaged via a second locking protrusion 21 and a positioning groove 12. For stable installation, the base 2 provides reliable support for the bottom of the circuit board component 3. The top of the housing 1 is equipped with a window lift button 4 and a safety button 5. The window lift button 4 cooperates with the glass touch switch 31 through a linkage mechanism 6, and the safety button 5 cooperates with the safety touch switch 32 through a pressing column 51, thereby realizing the lifting control of the car window and the triggering of the safety function, respectively. A linkage mechanism 6 is provided between the window lift button 4 and the glass touch switch 31. The linkage mechanism 6 includes a cooperative structure of steel ball 61 and spring 62, which is used to stably transmit the force applied by the window lift button 4 to the glass touch switch 31, so as to ensure that the sensitive operation effect can still be maintained under frequent use, and solve the problems of unstable button feedback and trigger delay in the prior art.

[0058] See Figure 1-6The linkage mechanism 6 includes a steel ball 61, which displaces and transmits pressure when the window lifting button 4 is pressed. A spring 62 is provided at the bottom of the steel ball 61, which provides elastic restoring force after the steel ball 61 is displaced by force, ensuring that the window lifting button 4 can be reset after operation and the glass touch switch 31 can be turned off, thereby avoiding the problem of circuit damage caused by prolonged contact of switch contacts. The cooperation between the steel ball 61 and the spring 62 not only enhances the stability of button operation, but also improves the durability and service life of the structure.

[0059] See Figure 3 , Figure 7 and Figure 8 The top of the outer casing 1 is provided with a button base 14, which is used to install the window lift button 4 and ensure the positioning accuracy of the window lift button 4 after installation. The button base 14 is provided with a plug groove 143, and the linkage mechanism 6 is located in the plug groove 143, so that the steel ball 61 and the spring 62 can work stably in a limited space. The bottom of the window lift button 4 is provided with a touch rod 44. When the touch rod 44 is subjected to force, it abuts against the linkage mechanism 6, thereby driving the steel ball 61 to press down the glass touch switch 31. The top of the linkage mechanism 6 abuts against the touch rod 44, and the bottom of the linkage mechanism 6 abuts against the glass touch switch 31, thereby ensuring that the driver's pressing action can be smoothly transmitted to the glass touch switch 31, realizing the stable triggering of the window lift function and solving the problem of force offset caused by improper installation in the prior art.

[0060] See Figure 3 , Figure 7 and Figure 8 Positioning pins 141 are provided on both sides of the button base 14. The positioning pins 141 play a precise limiting role during assembly. The glass lifting button 4 has first positioning holes 41 on both sides. When the glass lifting button 4 is installed on the button base 14, the positioning pins 141 extend into the first positioning holes 41 to ensure that the installation position of the glass lifting button 4 is fixed and does not shift, thereby improving the stability of operation and avoiding the failure problem caused by button loosening in the prior art.

[0061] See Figure 3 , Figure 7 and Figure 8The internal mirror image of the glass lift button 4 is provided with a limiting plate 42. A second positioning hole 421 is provided through the limiting plate 42. The axis of the second positioning hole 421 is collinear with the axis of the first positioning hole 41 to ensure positioning accuracy. A second guide groove 422 is provided on the opposite surface of the two limiting plates 42. The second guide groove 422 is aligned with the positioning post 141 during assembly to provide guidance during installation. When installing the glass lift button 4 onto the button base 14, the second guide groove 422 needs to be aligned with the positioning post 141 and pressure applied downwards. The positioning pin 141 passes through the second positioning hole 421 and the first positioning hole 41 to ensure that the button is stably limited in the vertical direction. Limiting seats 142 are provided on both sides of the bottom of the button seat 14. The limiting seats 142 are set in an arc shape. The two sides of the glass lifting button 4 rest against the limiting seats 142 to prevent the button from wobbling left and right during operation. An isolation plate 13 is provided between the two button seats 14. The isolation plate 13 is used to separate the two glass lifting buttons 4 to avoid operational interference between adjacent buttons, thereby improving the safety and accuracy of use.

[0062] See Figure 7-8 The top of the window lift button 4 is provided with anti-slip texture 43. The anti-slip texture 43 increases the friction to improve the grip stability of the driver when operating. It can prevent the button from slipping when the driver's hands are wet or the vehicle is in a bumpy environment, thus solving the problem of inconvenient operation in the prior art.

[0063] See Figure 3-7 The top of the outer casing 1 is provided with a base 15, which is used to install the safety button 5 and ensure that the safety button 5 maintains stable guidance during operation. The safety button 5 is movably inserted into the base 15, and a positioning hole 151 is provided through the base 15. A pressing post 51 is fixedly connected to the bottom center of the safety button 5. The pressing post 51 passes through the positioning hole 151 and corresponds to the safety touch switch 32. When the driver presses the safety button 5, the pressing post 51 drives the safety touch switch 32 to open, ensuring that the safety function can be quickly triggered in an emergency, thus solving the problem of insensitive triggering of the safety button in the prior art.

[0064] See Figure 3-7 The safety button 5 is symmetrically fixedly connected to a guide bar 52 inside. The guide bar 52 is engaged in the first guide groove 152 opened at both ends of the base 15, so that the safety button 5 maintains a stable and linear guide when moving up and down. Both ends of the safety button 5 are provided with limit grooves 53, and both ends of the base 15 are provided with hooks 153. The hooks 153 extend into the limit grooves 53 to limit the range of motion of the safety button 5, so as to prevent the safety button 5 from falling off or getting stuck during long-term use and ensure the reliability of the safety control function.

[0065] See Figure 5The upper surface of the base 2 is arrayed with supporting protrusions 22, which abut against the lower surface of the circuit board component 3 to ensure that the circuit board component 3 will not be displaced when subjected to operating force. The base 2 is symmetrically provided with second locking protrusions 21 on both sides, and the outer shell 1 is provided with positioning grooves 12 corresponding to the second locking protrusions 21 on both sides. The positioning grooves 12 engage with the second locking protrusions 21 to form a firm connection between the base 2 and the outer shell 1, which solves the problem of loose connection between the base and the outer shell in the prior art.

[0066] See Figure 3 Both sides of the outer casing 1 are provided with first locking protrusions 11. When the outer casing 1 is installed, the first locking protrusions 11 are engaged with the inner panel of the door, so that the entire window glass lifting switch assembly is firmly fixed to the inner panel of the door, thereby improving the overall device's vibration resistance during vehicle use.

[0067] Example 2:

[0068] See Figure 1-9 This embodiment provides a vehicle window lift switch. During vehicle installation, the outer casing 1 is engaged with the slots on the inner door panel via first locking protrusions 11 on both sides, ensuring a tight fit between the outer casing 1 and the inner door panel surface and guaranteeing the stability of the device within the overall door structure. A base 2 is inserted into the bottom of the outer casing 1. Second locking protrusions 21 are provided on both sides of the base 2, engaging with the positioning grooves 12 on both sides of the outer casing 1 to form an integral fixed structure between the outer casing 1 and the base 2. Supporting protrusions 22 are arrayed on the upper surface of the base 2, abutting against the lower surface of the circuit board component 3, providing uniform support and preventing warping or deformation due to single-point stress. The circuit board component 3 integrates electronic circuitry for controlling the window lift. A glass touch switch 31 and a safety touch switch 32 are fixedly mounted on the upper surface of the circuit board component 3, corresponding to the control of the window lift function and the safety protection function, respectively.

[0069] In actual use, when the driver presses the window lift button 4 on the top of the housing 1, the touch lever 44 of the window lift button 4 moves downward and abuts against the linkage mechanism 6. The linkage mechanism 6 consists of a steel ball 61 and upper and lower springs 62. The steel ball 61 moves downward under the action of the touch lever 44 and transmits the force to the glass touch switch 31 by compressing the lower spring 62, causing the glass touch switch 31 to conduct the circuit. After receiving the trigger signal, the circuit board component 3 drives the window motor to work, realizing the window glass lifting operation. When the driver releases the window lift button 4, the elastic force of the upper spring 62 pushes the steel ball 61 back to its original position, and the glass touch switch 31 disconnects the circuit, thus completing a complete window lifting operation cycle. In this embodiment, the setting of the steel ball 61 and the spring 62 ensures the sensitivity and elasticity of the button operation, solving the problem of unstable button feedback in the background art.

[0070] During the assembly of the window lift button 4, the button base 14 serves as a support and limiter. Positioning posts 141 are provided on both sides of the button base 14, which can be inserted into the first positioning holes 41 on both sides of the window lift button 4. A limit plate 42 is mirrored inside the window lift button 4. The second positioning hole 421 on the limit plate 42 is coaxial with the first positioning hole 41. The positioning posts 141 pass through the second positioning hole 421 and the first positioning hole 41 sequentially, ensuring precise vertical positioning of the window lift button 4. Second guide grooves 422 are provided on the opposite surfaces of the two limit plates 42. The second guide grooves 422 cooperate with the positioning posts 141 to provide guidance, making the installation process simple and efficient. Limit seats 142 are provided on both sides of the bottom of the button base 14. The limit seats 142 have an arc-shaped groove structure, which effectively limits the lateral swing of the window lift button 4, preventing shaking during operation. An isolation plate 13 is also provided between the two button bases 14 to separate different buttons and prevent interference during operation. The top of the window lift button 4 is provided with anti-slip texture 43, which can provide friction when the driver's hands are wet or the vehicle is bumpy, ensuring smooth operation.

[0071] When the driver needs to activate the safety function, they press the safety button 5 on the top of the housing 1. The safety button 5, through the pressing post 51, passes through the positioning hole 151 on the base 15 and contacts the safety touch switch 32, triggering the switch. After receiving the trigger signal, the circuit board component 3 executes the corresponding safety protection measures. In this embodiment, guide strips 52 are symmetrically fixedly connected inside the safety button 5. The guide strips 52 are embedded in the first guide grooves 152 at both ends of the base 15, so that the safety button 5 maintains stable linear guidance when moving up and down. Limiting grooves 53 are provided at both ends of the safety button 5. The hooks 153 at both ends of the base 15 extend into the limiting grooves 53 to form a limiting engagement, thereby preventing the safety button 5 from falling off during repeated operation and ensuring the long-term stable use of the safety function.

[0072] Through the above-described structural combination, the window glass lifting switch of this embodiment can achieve sensitive coordination between the button and the switch during use, ensuring the smooth lifting of the window glass; at the same time, the structural improvement of the safety button improves the triggering stability of the safety function; the overall installation method of the outer shell 1, base 2 and circuit board component 3 improves the vibration resistance and service life of the device, effectively solving the problems of unstable installation, insensitive operation and easy detachment of the safety button in the background technology.

[0073] The working principle of this utility model is as follows:

[0074] In use, the entire device is first fixedly installed on the inner panel of the car door by the outer shell 1. The first locking protrusions 11 on both sides of the outer shell 1 engage with the inner panel of the car door to make the outer shell 1 stably positioned. The bottom of the outer shell 1 is inserted into the base 2. The second locking protrusions 21 on both sides of the base 2 cooperate with the positioning grooves 12 on the outer shell 1. The support boss 22 at the upper end of the base 2 abuts against the lower end face of the circuit board component 3, thereby achieving stable support for the circuit board component 3.

[0075] When the driver needs to control the window operation, pressing the window control button 4 causes the touch lever 44 of the button to press downwards. This pressure is transmitted through the linkage mechanism 6. The linkage mechanism 6 includes a steel ball 61 and a spring 62 located at the lower end of the steel ball 61. When pressed, the steel ball 61 moves up and down under the elastic action of the spring 62, pushing the window touch switch 31 to open the window, thus controlling its movement. When the window control button 4 is released, the spring 62 returns to its original shape, the steel ball 61 returns to its original position, and the window touch switch 31 closes, completing one control cycle.

[0076] During the installation of the window lift button 4, the button base 14 provides the installation position. The positioning pins 141 on both sides of the button base 14 are inserted into the first positioning holes 41 on both sides of the window lift button 4. The limiting plate 42 inside the window lift button 4 is aligned with the positioning pins 141 through the second positioning hole 421. The second guide groove 422 on the limiting plate 42 is aligned with the positioning pins 141 and pressed downward, so that the positioning pins 141 pass through the second positioning hole 421 and the first positioning hole 41 in sequence, thereby achieving accurate positioning and guidance of the button. The limiting seats 142 at the bottom of both sides of the button base 14 are arc-shaped to limit the left and right swing of the window lift button 4 and keep it stable during operation. The isolation plate 13 between the button bases 14 separates the buttons on both sides to avoid mutual interference. The top of the window lift button 4 is provided with anti-slip texture 43 to provide friction when the driver's fingers operate it and prevent slippage.

[0077] When the safety control function needs to be triggered, the driver presses the safety button 5. The pressing pin 51 of the safety button 5 moves downward through the positioning hole 151 on the base 15, triggering the corresponding safety touch switch 32 to activate the safety function. A guide strip 52 is fixed inside the safety button 5. The guide strip 52 engages with the first guide grooves 152 at both ends of the base 15, ensuring the safety button 5 maintains stable linear movement. The limiting through grooves 53 at both ends of the safety button 5 cooperate with the hooks 153 of the base 15 to prevent the safety button 5 from falling off during use.

[0078] In summary, the glass lifting button 4 and the linkage mechanism 6 work together to achieve accurate control of the glass touch switch 31; the safety button 5 works together with the pressing column 51, the guide bar 52 and the hook 153 to achieve stable triggering of the safety touch switch 32; and the coordinated support structure of the housing 1, the base 2 and the circuit board component 3 ensures the overall stable installation and reliable use of the vehicle window lifting switch.

[0079] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
