[0002] Nowadays, the application of EPB switch function in automotive gear shift combination switches is quite widespread. The EPB button is usually integrated into the button structure inside the combination switch handle, so that pressing the button can trigger the EPB switch at the same time.

[0003] The common structural solution for these designs is to set up separate PCB boards for the button and EPB button, and then connect the two PCB boards with wire harnesses or FPCs. The connecting wire harnesses are electrically connected by plug-in, soldering or other methods, and then combined / merged and electrically connected to the body of the shift switch, so as to achieve functional synchronization of the button and EPB button.

[0004] However, the connection method between the two PCBs in the existing design is complex in structure and assembly, has many circuit nodes, a high probability of failure, and is also relatively expensive. Utility Model Content

[0005] In view of this, it is necessary to provide a combination switch handle for EPB and P gear synchronization to solve the problems of complex and high failure rate of existing EPB and synchronization mechanisms.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0032] In existing technologies, automotive gear shift switches integrating EPB functionality typically employ a separate PCB structure. The button 300 and the EPB switch are housed on independent circuit boards, physically connected via wiring harnesses or flexible circuit boards. This design requires additional components and soldering processes to achieve electrical signal transmission, resulting in a cumbersome assembly process. Multiple circuit nodes increase the risk of poor contact, potentially leading to signal attenuation or open circuits during long-term use.

[0033] This embodiment describes a synchronous combination switch handle for EPB and P gear, which relates to the field of combination switch technology. It integrates the switch and EPB onto the same FPC and uses the same button for triggering, which can achieve synchronous on / off switching of the two, simplify the structure, and reduce the failure rate and cost.

[0034] Please see Figures 1 to 7 This embodiment of a synchronous combination switch handle for EPB and P positions includes: a handle body 100, a circuit board assembly 200, and a button 300. The handle body 100 provides a structural foundation and effective support for the circuit board assembly 200 and the button 300. The circuit board assembly 200 integrates the switch and EPB, simplifying the structure. When manually pressed, the button 300 can simultaneously turn the switch and EPB on and off.

[0035] A circuit board assembly 200 is disposed on the handle body 100. The circuit board assembly 200 includes a sensing FPC 210, on which a first switch 211 for activating the EPB and a gold finger 212 for switching are integrated. Integrating the two triggering elements onto a single flexible circuit board simplifies the structure, reduces the number of circuit connection nodes, lowers the failure rate, and reduces assembly difficulty. A button 300 is slidably mounted in the handle body 100. The button 300 has a first abutment part 310 and a second abutment part 320. The first abutment can trigger the first switch 211, and the second abutment part 320 can trigger the gold finger 212. The button 300 can simultaneously drive the first abutment part 310 and the second abutment part 320 to move relative to each other, thereby synchronously triggering the first switch 211 and the gold finger 212, realizing the simultaneous conduction of vehicle and EPB signals.

[0036] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 7 Both the first switch 211 and the gold finger 212 are positioned relative to the button 300, with a height difference between them. The first switch 211 and the gold finger 212 are on different planes. The first abutment portion 310 and the second abutment portion 320 are respectively adapted to the heights of the first switch 211 and the gold finger 212. The heights of the first abutment portion 310 and the second abutment portion 320 are complementary to those of the first switch 211 and the gold finger 212, allowing the gold finger 212 to interact with the second abutment portion when the first switch 211 contacts the first abutment portion 310, thus enabling them to open and close synchronously. Since the interaction between the first switch 211 and the gold finger 212 and the button 300 occurs on different planes, uneven force between them and the button 300 can be avoided, preventing situations where the button is suspended and not activated.

[0037] In some embodiments, please refer to Figure 3 The circuit board assembly 200 also includes an FPC connector 213, which is integrated with the sensing FPC 210 via the FPC, eliminating the need for cable soldering, resulting in good integration, fewer solder joints, and a low failure rate.

[0038] In practical implementation, FPC plug 213 refers to the connection port at the end of the flexible printed circuit board. The sensing FPC 210 and FPC plug 213 are continuously formed using the same flexible substrate, eliminating the need for physical connection through soldering or inserts.

[0039] Specifically, the sensing FPC210 and FPC plug 213 are manufactured as a single flexible circuit board, directly connected by a pre-set conductive line. During assembly, when the FPC plug 213 is inserted into an external connector, the first switch 211 and gold fingers 212 on the sensing FPC210 can transmit signals through the integrated circuit. This integrated connection structure eliminates the wiring harness connection between two independent PCBs in traditional solutions, allowing the circuit board assembly 200 to form a complete signal path.

[0040] Compared to existing technologies, traditional solutions require separate manufacturing of the EPB switch PCB and the button 300 PCB, followed by wiring harness connection via soldering or plug-in, increasing assembly steps and introducing the risk of poor soldering. This solution integrates the signal transmission path onto a single flexible circuit board using an integrated FPC structure, reducing the number of physical interfaces between circuit boards and avoiding contact problems caused by connector plugging and unplugging.

[0041] In some embodiments, please refer to Figure 3 The first switch 211 is a micro switch. The first switch 211 is electrically connected to the sensing FPC 210. It can switch the switch under very small pressing action, making the first switch 211 more accurate and more sensitive, thereby transmitting signals with the help of the sensing FPC 210.

[0042] The pins of the micro switch are soldered to the inductive FPC210, so that the contacts of the micro switch and the conductive lines of the inductive FPC210 are directly connected.

[0043] Specifically, the micro switch is integrated on the surface of the sensing FPC210. ​​When the button 300 is subjected to external force, the first abutment part 310 pushes the trigger mechanism of the micro switch to generate displacement, causing the internal contacts to close and form an electrical signal. Since the micro switch is directly connected to the circuit layer of the sensing FPC210, the signal transmission does not need to go through an additional wiring harness or intermediate connector, and the signal path is shortened to a line extension within a single conductive layer.

[0044] Compared with existing technologies, traditional solutions require a separate PCB board for the EPB function switch and connection via wiring harness. However, this solution directly places the micro switch on the sensing FPC210, which not only eliminates the assembly process of a separate PCB board, but also avoids the risk of poor contact caused by wiring harness soldering or plug-in connection.

[0045] In some embodiments, please refer to Figure 4and Figure 7 A silicone button 330 is provided between the gold finger 212 and the second abutment 320. The second abutment 320 can drive the silicone button 330 to trigger the gold finger 212. The silicone button 330 can provide the button 300 force value feel and signal.

[0046] In practical implementation, the silicone button 330 refers to the elastic button 300 made of silicone material. Specifically, it can be made of soft silicone material, which has good resilience and wear resistance. When pressed, it transmits the pressing force through deformation, while avoiding wear problems caused by rigid contact.

[0047] Specifically, when button 300 is pressed, the second abutment part 320 pushes the silicone button 330 towards the gold finger 212. Due to elastic deformation, the silicone button 330 displaces, and its bottom conductive layer or conductive contact comes into contact with the surface of the gold finger 212, forming a conductive circuit and triggering the function. The elastic properties of the silicone button 330 allow it to automatically reset after pressure is released, preventing poor contact due to residual deformation. Furthermore, the insulating properties of the silicone button 330 isolate direct friction between metal parts, reducing circuit failures caused by metal oxidation or wear.

[0048] In some embodiments, please refer to Figure 3 and Figure 7 The circuit board assembly 200 also includes a reinforcing plate 220, which is connected to the back of the sensing FPC 210. The reinforcing plate 220 can sense the FPC 210 to form effective support, significantly improving the bending resistance of key parts.

[0049] In some embodiments, the reinforcing plate 220 may be made of PI plastic and bonded to the non-conductive surface of the inductive FPC 210 by adhesive bonding. The reinforcing plate 220 increases structural rigidity, preventing excessive bending deformation of the flexible circuit board during assembly or use.

[0050] The back connection of the sensing FPC210 refers to the reinforcing plate 220 being placed on the side opposite to the circuit component arrangement surface of the flexible circuit board, which neither affects the circuit layout nor hinders the effective support.

[0051] Specifically, during assembly, the reinforcing plate 220 is fixed to the non-working surface of the sensing FPC 210, forming a composite layered structure. When the handle body 100 is subjected to external pressure or vibration, the reinforcing plate 220 prevents local deformation of the flexible circuit board by dispersing stress. This structural design is particularly suitable for applications with sliding components, such as when the button 300 reciprocates within the assembly cavity 122. The reinforcing plate 220 can effectively absorb the mechanical impact transmitted by the button 300's movement, preventing misalignment when the gold finger 212 contacts the second abutment part 320.

[0052] Compared to existing technologies, traditional solutions expose the flexible circuit board directly to mechanical motion, making it prone to fatigue fracture over long-term use. This solution, by adding a reinforcing plate 220, maintains the support strength of key parts of the circuit board while preserving the flexibility of the FPC, facilitating FPC fixation and spatial arrangement.

[0053] Existing technologies typically require additional mounting brackets to secure circuit boards, while this solution achieves a self-supporting structure for the circuit board assembly 200 through the cooperation of the reinforcing plate 220 and the frame slot 121.

[0054] In some embodiments, please refer to Figure 2 and Figure 6 The handle body 100 includes a housing 110 and a mounting frame 120. The mounting frame 120 is disposed within and detachably connected to the housing 110. The circuit board assembly 200 and the buttons 300 are both disposed within the mounting frame 120. The mounting frame 120 serves as a support structure, supporting the circuit board assembly 200 and the buttons 300. The housing 110 encapsulates and protects the mounting frame 120 and the circuit board assembly 200.

[0055] Please note: Please refer to [link / reference]. Figure 2 The outer casing 110 includes a housing 111, a rear cover 112, and a decorative ring 113. The assembly frame 120 is snapped into the housing 111. The rear cover 112 is snapped into the side of the housing 111 to further secure the assembly frame 120. The end of the decorative ring 113 is snapped into the assembly frame 120. The assembly frame 120 and the decorative ring 113 are locked and connected by a snap fastener to form the outer casing 110. This simplifies the assembly process of the outer casing 110 and improves production efficiency.

[0056] As a further embodiment, the assembly frame 120 is provided with a frame slot 121 in the middle. The frame slot 121 is set perpendicular to the axis of the handle body 100. The reinforcing plate 220 is snapped into the frame slot 121. The frame slot 121 can position and limit the reinforcing plate 220, so that the reinforcing plate 220 is fixed in the assembly frame 120, thereby fixing the circuit board assembly 200 and ensuring that the circuit board assembly 200 can withstand the pressure impact from the button 300.

[0057] In practical implementation, the skeleton slot 121 refers to the groove structure opened in the middle of the assembly skeleton 120, whose extension direction is perpendicular to the axis of the handle body 100. Specifically, the groove can be formed on the assembly skeleton 120 by injection molding process to accommodate the reinforcing plate 220 and restrict its displacement. The reinforcing plate 220 is embedded into the skeleton slot 121 by a snap-fit ​​or protrusion structure. Specifically, it can be fixed by elastic snap-fit ​​or positioning boss, and the mechanical snap-fit ​​method prevents the reinforcing plate 220 from loosening under vibration.

[0058] Specifically, the assembly frame 120 serves as the internal support structure of the handle body 100. Its frame slot 121 is perpendicular to the handle's axis, allowing the reinforcing plate 220 to form a stable planar contact with the frame after being inserted laterally. After the reinforcing plate 220 is connected to the back of the sensing FPC 210, it is fixed in the frame slot 121 via a snap-fit ​​mechanism, thus preventing FPC misalignment due to assembly errors or external impacts. During assembly, the reinforcing plate 220 can be directly pushed into the frame slot 121 in a direction perpendicular to the handle's axis to complete the fixation, without the need for additional fasteners or adhesive bonding.

[0059] The assembly frame 120 has an assembly cavity 122 at one end relative to the button 300. The assembly cavity 122 is arranged along the axis of the handle body 100 and is connected to the frame slot 121. The button 300 is slidably engaged in the assembly cavity 122 and can move along the assembly cavity 122 to trigger the sensing FPC 210 located on the frame slot 121, thereby realizing signal transmission.

[0060] In the specific implementation process, the assembly cavity 122 refers to the cavity structure set inside the assembly frame 120 to accommodate the button 300. Specifically, it can be realized by injection molding process to form a cavity structure that communicates with the frame slot 121, and its axial direction is consistent with the extension direction of the handle body 100.

[0061] The button 300 and the assembly cavity 122 are limited to linear movement through the cooperation of the guide groove and the protrusion. Specifically, a slide rail structure with lateral limiting ribs can be used to achieve this, so that the button 300 maintains a stable movement trajectory during the pressing process.

[0062] Specifically, the assembly cavity 122 extends along the axis of the handle body 100, forming a communicating space with the frame slot 121. The reinforcing plate 220 is fixed in the frame slot 121, while the button 300 is embedded in the assembly cavity 122 by a sliding snap-fit ​​method. When the button 300 is pressed, its movement direction is parallel to the axis of the handle body 100, and the first abutment part 310 and the second abutment part 320 respectively trigger the corresponding switch and the gold finger 212. Since the assembly cavity 122 is connected to the frame slot 121, the mating space between the circuit board assembly 200 and the button 300 is integrated into a continuous structure, avoiding the assembly errors caused by the splicing of independent cavities in traditional designs.

[0063] In some specific embodiments, the sidewall of the assembly cavity 122 may be provided with a groove, and corresponding ribs may be provided on both sides of the button 300, so that the ribs of the button 300 are engaged in the groove of the sidewall of the assembly cavity, thereby effectively limiting the button. In addition, a limiting stop may be provided at the opening end of the assembly cavity 122 to prevent the button 300 from excessively displacing and detaching from the cavity.

[0064] Workflow: The handle body 100 serves as the main structural support, with an internal frame 120 providing a mounting position for the circuit board. The flexible sensing circuit board, reinforced by a reinforcing plate 220, is then inserted into the frame slot, ensuring effective positioning and fastening of the switch and the gold finger 212. When the button 300 slides axially, the first abutment part 310 presses down, triggering the micro switch and simultaneously causing the second abutment part 320 to contact the gold finger 212. Both trigger actions are completed through the same button 300 travel, and the circuit signal is directly transmitted through the integrated flexible circuit board, eliminating the need for cross-circuit board connections.

[0065] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the present utility model.
