TECHNICAL FIELD

[0001] The present application relates to the field of mechanical switches, in particular to a multifunctional integrated mechanical switch of an automobile seat. BACKGROUND

[0002] At present, with the improvement of people's living standards, users' demand for driving and riding comfort is increasingly strong, which makes the functional integration of automotive interior components become an important development trend. Today, the functions of automobile seats are extremely rich, covering front and rear adjustment, backrest pitch adjustment, ventilation, heating, massage and other function modules.

[0003] In related technologies, the industry usually uses independent button type switch groups to solve the problem of function control of automobile seats, that is, each function corresponds to an independent button, and there are special buttons for functions such as seat forward and backward movement, backrest angle adjustment, ventilation, heating, massage, etc. When people use the car, they click the corresponding button according to the actual needs, and then start the corresponding function module.

[0004] For the related technologies in the above, the following defects exist: In the car, the setting of each independent button needs to occupy a certain space, multiple independent buttons are set in the car at the same time, the line is complex, and the sand tower is formed, which occupies a large space together, reduces the effective utilization space in the car. SUMMARY

[0005] In order to improve the space utilization in the car, the present application provides a multifunctional integrated mechanical switch of an automobile seat.

[0006] The multifunctional integrated mechanical switch of an automobile seat provided by the present application adopts the following technical scheme:

[0007] A multifunctional integrated mechanical switch of an automobile seat, comprising a shell, a reset swing rod and a plurality of self-reset transmission mechanisms, the first end of the reset swing rod is arranged on the inner side of the shell, the second end of the reset swing rod is arranged on the outer side of the shell, and the first end of the reset swing rod is hinged to the shell bottom;

[0008] The self-reset transmission mechanism is arranged on the inner side of the shell, and a plurality of self-reset transmission mechanisms are distributed along the circumference of the reset swing rod;

[0009] The self-reset transmission mechanism comprises a switch unit, a transmission assembly and a sliding block, the switch unit is fixedly arranged on the shell bottom, the sliding block is arranged between the reset swing rod and the switch unit, the reset swing rod is connected with the sliding block through the transmission assembly, and the reset swing rod pushes the sliding block to move back and forth between the reset swing rod and the switch unit through the transmission assembly.

[0010] By adopting the technical scheme, the shell protects the internal components of the entire mechanical switch. The plurality of switch units are in one-to-one correspondence with components for functions such as front and rear adjustment, backrest pitch adjustment, ventilation, heating, massage, and the like. The switch units select a normally open pressure switch or a self-locking button switch according to the operation requirements of the corresponding components. For example, components that need to be operated for a short time, such as front and rear adjustment and backrest pitch adjustment, can select a normally open pressure switch, and components that need to be continuously operated for a long time, such as ventilation, heating, and massage, can select a self-locking button switch. When the switch unit is started, the self-resetting transmission mechanism can be triggered by swinging the reset swing lever. The transmission assembly pushes the sliding block to reciprocate between the reset swing lever and the switch unit, and then the sliding block triggers the switch unit or moves away from the switch unit. In summary, the present application can adjust the swing angle of the reset swing lever to trigger the functions of each switch unit. Compared with the prior art, the plurality of keys are reduced to one reset swing lever, and the space utilization in the car is improved.

[0011] Preferably, the self-resetting transmission mechanism further comprises a sliding rail, which is arranged radially on the side of the reset swing lever and connected with the shell bottom; and the sliding block is arranged in the sliding groove of the sliding rail.

[0012] The switch unit and the transmission assembly are both mounted on the sliding rail.

When the transmission assembly is running, the reset swing lever rotates to push the swing support to rotate. The swing support pushes the sliding block towards the switch unit through the connecting support until the sliding block triggers the switch unit. When the reset swing lever is released, the reset swing lever resets itself. At this time, under the elastic force of the reset spring, the swing support resets, and the sliding block moves away from the switch unit.

When both ends of the insertion rod are located within the guide hole, the locking of the ball head can be released. The straight tube connects to the ball head, forming the main body of the reset lever, facilitating user operation and enabling adjustment of seat-related functions.

[0031] Preferably, the insertion rod is connected to the inner wall of the middle part of the straight tube by a first reset elastic element;

[0068] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0069] This application discloses a multi-functional integrated mechanical switch for automotive seats.

[0070] Reference Figure 1 , Figure 2 and Figure 3 A multi-functional integrated mechanical switch for automotive seats includes a housing 1, a reset lever 2, and multiple self-resetting transmission mechanisms 3. The housing 1 protects the internal components of the entire mechanical switch. The first end of the reset lever 2 is located inside the housing 1, and the second end of the reset lever 2 is located outside the housing 1. The first end of the reset lever 2 is hinged to the bottom 11 of the housing 1.

[0071] Reference Figure 2 , Figure 3 and Figure 4 The self-resetting transmission mechanism 3 is located inside the outer casing 1, and multiple self-resetting transmission mechanisms 3 are distributed along the circumference of the reset lever 2.

[0072] Reference Figure 3 and Figure 5 The self-resetting transmission mechanism 3 includes a switch unit 30, a transmission component 33, and a slider 32. The switch unit 30 is fixed to the bottom of the housing 11. The slider 32 is located between the reset rocker arm 2 and the switch unit 30. The reset rocker arm 2 is connected to the slider 32 through the transmission component 33, and the transmission component 33 pushes the slider 32 to reciprocate between the reset rocker arm 2 and the switch unit 30.

[0073] Reference Figure 3 and Figure 5In this embodiment, the outer casing 1 protects the internal components of the entire mechanical switch. Multiple switch units 30 are connected one-to-one with components corresponding to various functions such as fore-and-aft adjustment, backrest tilt adjustment, ventilation, heating, and massage. The switch unit 30 selects either a normally open pressure switch or a self-locking push-button switch based on the operational requirements of the corresponding component. For example, components requiring short-term operation, such as fore-and-aft adjustment and backrest tilt adjustment, can use normally open pressure switches, while components requiring long-term continuous operation, such as ventilation, heating, and massage, can use self-locking push-button switches. When the switch unit 30 is activated, the self-resetting transmission mechanism 3 is triggered by swinging the reset lever 2. The transmission component 33 pushes the slider 32 to reciprocate between the reset lever 2 and the switch unit 30, thereby causing the slider 32 to either trigger the switch unit 30 or move away from the switch unit 30. In summary, this application can achieve the function of triggering each switch unit 30 separately by adjusting the swing angle of the reset lever 2. Compared with the prior art, multiple buttons are reduced to a single reset lever 2, improving the space utilization within the vehicle.

[0074] Reference Figure 3 and Figure 5 The self-resetting transmission mechanism 3 also includes a slide rail 31, which is radially disposed on the side of the reset lever 2 and connected to the bottom of the housing 11; the slider 32 is disposed in the slide groove 3101 of the slide rail 31. The switching unit 30 and the transmission assembly 33 are both mounted on the slide rail 31. The transmission assembly 33 includes a swing bracket 330 and a connecting bracket 334. The first end of the swing bracket 330 is hinged to the slide rail 31 and is also connected to the slide rail 31 with a reset torsion spring 331; the second end of the swing bracket 330 is used to contact the reset lever 2; one end of the connecting bracket 334 is hinged to the swing bracket 330 and the other end is hinged to the slider 32.

[0075] Reference Figure 3 and Figure 5 In this embodiment, the slide rail 31 provides a stable sliding path for the slider 32, making the movement of the slider 32 more accurate and smooth. Integrating the slider 32, the switch unit 30, and the transmission assembly 33 onto the slide rail 31 achieves integrated integration of all components of the self-resetting transmission mechanism 3, which helps to reduce the overall size, improve space utilization, and facilitate the integration of more functions into a compact mechanical switch, thereby reducing assembly difficulty and cost during production. When the transmission assembly 33 is running, the reset lever 2 rotates, pushing the swing bracket 330 to rotate. The swing bracket 330 pushes the slider 32 toward the switch unit 30 through the connecting bracket 334 until the slider 32 triggers the switch unit 30. Releasing the reset lever 2 causes it to reset automatically. At this time, under the elastic force of the reset spring, the swing bracket 330 resets, and the slider 32 moves away from the switch unit 30.

[0076] Reference Figure 3 andFigure 5 The second end of the swing bracket 330 is provided with a pressure member 333 pointing towards the reset swing rod 2, and the pressure member 333 is provided with a positioning groove 3301 that is directly opposite to the reset swing rod 2. In this embodiment of the application, the swing bracket 330 and the reset swing rod 2 can better cooperate, accurately respond to the operation, and improve the accuracy and reliability of the switch operation.

[0077] Reference Figure 3 and Figure 5 A limiting member 332 is provided on the side of the swing bracket 330 away from the slider 32. The limiting member 332 is arranged along the axial direction of the reset swing rod 2 and is connected to the slide rail 31. In this embodiment, the limiting member 332 can limit the rotation angle of the swing bracket 330, so that the swing bracket 330 swings within a reasonable range, ensuring the stable and reliable operation of the self-resetting transmission mechanism 3.

[0078] Reference Figure 3 and Figure 5 A pressing rod 34 is provided between the slider 32 and the switch unit 30, extending along the length of the slide rail 31. The pressing rod 34 is connected to the slider 32. A limiting tube 35, connected to the slide rail 31, is fitted onto the pressing rod 34. In this embodiment, the pressing rod 34 can move along the length of the slide rail 31 with the slider 32 and trigger the switch unit 30 to complete the function switching; the limiting tube 35 is fitted onto the pressing rod 34 to restrict the movement position of the pressing rod 34, ensuring its movement direction is stable and accurate, and improving the overall stability and reliability of the mechanical switch.

[0079] Reference Figure 1 A coaxial reset elastic horn tube 20 is sleeved on the reset lever 2. The smaller diameter end of the reset elastic horn tube 20 is connected to the second end of the reset lever 2, and the larger diameter end of the reset elastic horn tube 20 is connected to the top 12 of the outer casing 1. In this embodiment, the reset elastic horn tube 20, sleeved on the reset lever 2 and connected to the top 12 of the outer casing 1, provides elastic restoring force after the reset lever 2 swings, allowing it to quickly return to its initial position, ensuring the repeatability and stability of the switch operation. Simultaneously, this connection method also provides a certain degree of dustproof and protective function, preventing external dust and debris from entering the switch and affecting its normal operation, thus extending the switch's service life.

[0080] Reference Figure 2The top of the housing 12 is provided with multiple guide grooves 101 radially disposed on the side of the reset lever 2, and the multiple guide grooves 101 are distributed circumferentially along the reset lever 2. Each guide groove 101 corresponds to a different slide rail 31, and the guide grooves 101 are connected to the end facing the reset lever 2. In this embodiment, the multiple radial guide grooves 101 distributed circumferentially along the reset lever 2 on the top of the housing 12 can provide guidance for the swing of the reset lever 2. Simultaneously, the fact that the guide grooves 101 correspond to the slide rails 31 and are connected to the end facing the reset lever 2 makes the swing of the reset lever 2 more stable, improving the accuracy and reliability of the switch operation.

[0081] Reference Figure 4 The reset lever 2 includes a base 21, a ball head 22, and a straight tube 23. The base 21 is mounted on the bottom of the housing 11 and has a spherical groove 2101 and a coaxial insertion hole 2102. The ball head 22 is located inside the spherical groove 2101 and has a guide hole 2201 coaxial with the insertion hole 2102. A coaxial insertion rod 221 is located inside the guide hole 2201 and is slidably connected to the ball head 22 along the axial direction of the guide hole 2201. One end of the insertion rod 221 is located inside the guide hole 2201, and the other end is located inside the insertion hole 2102. The straight tube 23 is coaxially located at the end of the guide hole 2201 away from the base 21, and the first end of the straight tube 23 is connected to the ball head 22.

[0082] Reference Figure 4 In this embodiment, the base 21 is mounted on the bottom of the housing 11, providing a stable support foundation for the reset lever 2. The spherical groove 2101 and the insertion hole 2102 provide accurate installation positions and movement guidance for the ball head 22 and the lever 221. The ball head 22 is located in the spherical groove 2101, allowing the reset lever 2 to rotate flexibly and expanding the operating angle range. The guide hole 2201 provides a path for the sliding of the lever 221, ensuring that the lever 221 can smoothly slide and connect with the ball head 22 in the axial direction of the guide hole 2201. The sliding of the lever 221 within the guide hole 2201 can meet different adjustment requirements. When one end of the lever 221 is located in the guide hole 2201 and the other end is located in the insertion hole 2102, the relative positions of the base 21 and the ball head 22 can be locked. When both ends of the lever 221 are located within the guide hole 2201, the locking of the ball head 22 can be released. The straight tube 23 is connected to the ball head 22 to form the main body of the reset lever 2, which is convenient for users to operate and adjust the seat-related functions.

[0083] Reference Figure 4From the first end to the second end of the straight tube 23, a first support member 24 and a second support member 25 are sequentially installed inside the straight tube 23. The first support member 24 is connected to the insertion rod 221 by a first reset elastic member 241, and the first support member 24 is provided with a first rope hole 2401. The second support member 25 is provided with a second rope hole 2501 and a third rope hole 2502, and the third rope hole 2502 is coaxial with the straight tube 23. The reset swing rod 2 also includes a pressure rod 26 and a pull rope 27. The pressure rod 26 is coaxially spaced within the third rope hole 2502, and the first end of the pressure rod 26 is provided with a connector 261 located between the first support member 24 and the second support member 25. The first end of the pull rope 27 is connected to the insertion rod 221, and the second end of the pull rope 27 passes through the first rope hole 2401, the second rope hole 2501 and the third rope hole 2502 in sequence before being connected to the connector 261. The second end of the pressure rod 26 is provided with a pressing head 262 extending to the outside of the straight tube 23. A guide tube 264 is provided between the pressing head 262 and the second support member 25, which is sleeved on the pressure rod 26 and connected to the straight tube 23.

[0084] Reference Figure 4 In this embodiment, the reset lever 2 adopts a unique structure including a base 21, a ball head 22, a straight tube 23, and a plug 221. Combined with a first support member 24, a second support member 25, a first reset elastic member 241, a pull rope 27, and a pressure rod 26, it achieves coordinated control of the movement of the plug 221 and the pressure rod 26. Pressing the pressing head 262 at the end of the pressure rod 26 can drive the pull rope 27 to pull the plug 221, thus moving the plug 221. The first reset elastic member 241 also enables the automatic reset function of the plug 221. The guide tube 264 ensures the stability of the movement of the pressure rod 26 and optimizes the user experience of the switch. By combining the outer shell 1, reset lever 2, multiple self-resetting transmission mechanisms 3, slide rail 31, pressure-bearing component 333, limiting component 332, pressure bar 34, limiting tube 35, reset elastic horn tube 20, guide groove 101 and other structures, a multi-functional integrated control of the car seat is realized. A single switch can realize the switching of multiple seat functions, reduce the space occupied by the control panel, reduce the complexity of the wiring harness and production costs, and the mechanical design improves reliability and ease of operation.

[0085] Reference Figure 4 A second reset elastic element 265 is connected between the guide tube 264 and the pressing head 262. An elastic cover 263 covering the pressing head 262 is installed at the second end of the straight tube 23.

[0086] Reference Figure 4 Figure 4In this embodiment, the second reset elastic element 265 enables the pressing head 262 to reset after being pressed, ensuring the smoothness and stability of multiple pressing operations of the reset lever 2; the elastic cover 263 can protect the pressing head 262, prevent dust, debris and other contaminants from entering, and improve the service life of the pressing head 262 and the reliability of the entire mechanical switch.

[0087] The implementation principle of a multi-functional integrated mechanical switch for a car seat according to an embodiment of this application is as follows:

[0088] Multiple switch units 30 are connected one-to-one to components corresponding to multiple functions such as fore-and-aft adjustment, backrest tilt adjustment, ventilation, heating, and massage. The switch unit 30 selects a normally open pressure switch or a self-locking push button switch according to the operating requirements of the corresponding component. For example, components that need to operate briefly, such as fore-and-aft adjustment and backrest tilt adjustment, can select a normally open pressure switch, while components that need to operate continuously for a long time, such as ventilation, heating, and massage, can select a self-locking push button switch.

[0089] When the switch unit 30 is activated, pressing the pressing head 262 at the end of the pressing rod 26 first drives the pull rope 27 to pull the insertion rod 221, thus moving the insertion rod 221 out of the insertion hole 2102, releasing the lock on the ball head 22, and allowing the ball head 22 and the straight rod to swing freely. Then, swinging the reset lever 2 triggers the self-resetting transmission mechanism 3. The reset lever 2 pushes the swing bracket 330 to rotate. The swing bracket 330 pushes the slider 32 towards the corresponding switch unit 30 through the connecting bracket 334, until the slider 32 triggers the switch unit 30. The reset torsion spring 331 then causes the swing bracket 330 to return to its initial position when the reset lever 2 resets, at which point the slider 32 also moves away from the switch unit 30.

[0090] When the switch unit 30 is not needed, releasing the pressure on the pressing head 262 allows the reset elastic horn tube 20 to provide elastic restoring force after the reset lever 2 swings, quickly returning it to its initial position. The first reset elastic element 241 also enables the automatic reset function of the insertion rod 221, allowing it to be reinserted into the insertion hole 2102, thus locking the ball head 22 and the straight rod.
