Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, it relates to an automotive electronic gear shifting mechanism. Background Technology

[0002] The gear shifter is a crucial component of a car. Early gear shift mechanisms were all mechanical, primarily used in automatic transmission vehicles. With the rapid development of automotive electronics technology and the increasing demand for personalization from drivers, electronic gear shifters have become widely used in luxury and new energy vehicles to further enhance their sense of luxury and technology. In recent years, the market penetration rate of electronic gear shifters has been rapidly increasing. Under the increasingly stringent cost control measures of OEMs, more and more complex mechanical components are being replaced by electronic ones. Adopting electronic shifting, while saving costs, allows for the elimination of some mechanical structures by transmitting shift information via electrical signals, freeing up space in the center console for storage.

[0003] In existing electronic gear shift mechanisms: 1. The baffle plate and circuit board are separate, and the connection between the baffle plate and the shift mechanism body is that it is inserted into a groove on the shift mechanism body. This structure has the following defects: The silicone pad baffle plate is not fixed in the Z-direction. After it loosens, it cannot reliably restrict the silicone pad in the Z-direction. After pressing the unlock button (UNLOCK button) repeatedly, the nickel particles on the silicone pad may no longer contact the gold fingers on the circuit board, resulting in the gear shift lever being unable to unlock; 2. During the assembly process of the existing structure, the silicone pad baffle plate may fall off. Initially, the electrical test cannot identify it. As the product enters the market, with users pressing the UNLOCK button and vibrations during vehicle operation, the silicone pad and the gold fingers on the circuit board gradually become misaligned until they can no longer conduct properly, affecting product reliability.

[0004] Existing technology includes a protective cover for an electronic gear shift display, titled "A Protective Cover for an Automotive Gear Shift Display," with publication number CN211259612U. This technology discloses a protective cover for an electronic gear shift display, comprising a panel, a clamping plate installed inside the panel, a circuit board laid inside the panel, and an electronic display protective cover placed above the circuit board. A sealing strip is installed inside the electronic display protective cover, and fixing bolts are inserted into the cover. A gear shift sign is snapped onto the top of the panel, and a button is embedded inside the gear shift sign. This invention, by setting a baffle erected on the main body of the cover, surrounds the LED lights on the circuit board, and a sealing strip is fixed to the top of the baffle. The sealing strip adheres tightly to the circuit board, effectively preventing light leakage. Simultaneously, by encasing the circuit board in the electronic display protective cover, it prevents liquid from seeping into the circuit board and causing a short circuit, greatly improving the protective performance of the device.

[0005] However, this technology does not address the technical issues and solutions of this application. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an automotive electronic gear shifting mechanism that, in view of the shortcomings of the prior art, ensures the Z-axis limiting of the silicone pad after the baffle and circuit board are installed, reduces the probability of unlocking failure, and prevents the baffle from falling off after the baffle and circuit board are fixed and assembled into the lower housing, thereby improving the overall performance.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] This utility model is an electronic gear shifting mechanism for automobiles, including a gear shifting mechanism body, a baffle, a circuit board, and a positioning post. The gear shifting mechanism body is provided with a groove, the baffle is connected to the circuit board, the circuit board is provided with a circuit board positioning hole and a circuit board bolt hole, the groove is provided with a groove positioning hole and a groove threaded hole, and the gear shifting mechanism body is provided with an unlock button.

[0009] The baffle is fixedly connected to the circuit board by screws, and the baffle and circuit board are configured to be snapped into the groove.

[0010] A silicone pad is provided on the side of the baffle, and the silicone pad is connected to the unlock button.

[0011] The circuit board has a circuit board positioning hole at one end near the baffle and another circuit board positioning hole at the other end away from the baffle.

[0012] A groove positioning hole is provided on the end of the groove near the baffle, and another groove positioning hole is provided on the end of the circuit board away from the baffle.

[0013] The circuit board has threaded holes on each side near the baffle and on each side away from the baffle.

[0014] The groove portion is provided with threaded holes on each side near the baffle, and the circuit board is provided with threaded holes on each side away from the baffle.

[0015] The gear shifting mechanism body includes a lower housing and an upper housing, with a groove located inside the lower housing and the upper housing fastened to the lower housing.

[0016] The circuit board has a folded edge on one side, a baffle is attached to the folded edge, and screws pass through the folded edge to connect to the baffle.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] The automotive electronic gear shifting mechanism described in this utility model improves upon some aspects of its structure. The shifting mechanism includes a shifting mechanism body, a baffle, a circuit board, and a positioning post. An unlock button is provided on the shifting mechanism body. Pressing the unlock button unlocks the gear shifting mechanism. A recessed portion is provided on the shifting mechanism body, and the baffle is fixedly connected to the circuit board, possibly via screws. The circuit board has positioning holes and bolt holes, while the recessed portion has positioning holes and threaded holes. When installing the circuit board, the positioning post passes through the positioning holes and the recessed portion to position the circuit board within the recessed portion. Then, bolts pass through the bolt holes and the threaded holes to secure the circuit board within the recessed portion. The fixed connection between the baffle and the circuit board ensures the baffle's position is fixed, reliably limiting the silicone pad and preventing it from loosening after repeated presses of the unlock button. Because the silicone pad remains secure, the reliable connection between the nickel particles on the silicone pad and the gold fingers on the circuit board is effectively guaranteed, ensuring the reliable performance of the shifting mechanism. The structure of this utility model solves two problems. On the one hand, the baffle and the circuit board are fixed together with screws. Because the circuit board is fixedly installed, the baffle is fixed. The baffle can reliably restrict the Z-axis of the silicone pad, ensuring that the nickel particles on the silicone pad are reliably connected to the gold fingers on the circuit board. On the other hand, the baffle and the circuit board are first connected together and then assembled into the groove on the lower housing. In this way, the circuit board and the baffle are no longer assembled separately, and the situation of the baffle falling off during installation will not occur. Attached Figure Description

[0023] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:

[0024] As attached Figure 1 -Appendix Figure 2 As shown, this utility model is an electronic gear shifting mechanism for automobiles, including a gear shifting mechanism body 6, a baffle 4, a circuit board 5, and a positioning post 7. The gear shifting mechanism body 6 has a groove 8. The baffle 4 connects to the circuit board 5. The circuit board 5 has a circuit board positioning hole 9 and a circuit board bolt hole 10. The groove 8 has a groove positioning hole and a groove threaded hole. An unlock button 2 is provided on the gear shifting mechanism body 6. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In terms of structural design, the local structure of the gear shifting mechanism is improved. The gear shifting mechanism includes a gear shifting mechanism body 6, a baffle 4, a circuit board 5, and a positioning post 7. An unlock button 2 is provided on the gear shifting mechanism body 6. The connection relationship of the electronic gear shifting mechanism described in this utility model is as follows: the UNLOCK button is connected to a silicone pad, and the nickel particles of the silicone pad are connected to the gold fingers of the circuit board. To prevent frequent pressing of the UNLOCK button from causing the silicone pad to move in the Z-direction, leading to a circuit malfunction, a baffle 4 is provided on the silicone pad 3. The function of the baffle 4 is to prevent the silicone pad 3 from loosening or moving away from the unlock button 2 in the Z-direction. Pressing the unlock button 2 unlocks the gear shift mechanism. The gear shift mechanism body 6 has a recessed section 8, and a baffle 4 is fixedly connected to the circuit board 5, possibly via screws. The circuit board 5 has a circuit board positioning hole 9 and a circuit board bolt hole 10. The recessed section 8 has a recessed section positioning hole and a recessed section threaded hole. When the circuit board needs to be installed, the positioning pin 7 passes through the circuit board positioning hole 9 and the recessed section positioning hole to position the circuit board 5 within the recessed section. Then, the bolt 12 passes through the circuit board bolt hole 10 and the recessed section threaded hole to fix the circuit board 5 within the recessed section 8. Since the baffle 4 is fixedly connected to the circuit board 5, the position of the baffle 4 is fixed, reliably limiting the silicone pad 3 and preventing the silicone pad 3 from loosening after multiple presses of the unlock button 2. Because the silicone pad 3 does not loosen, the reliable connection between the nickel particles on the silicone pad 3 and the gold fingers on the circuit board 5 is effectively guaranteed, ensuring the reliable performance of the gear shift mechanism. This invention addresses two key issues. First, the baffle 4 and circuit board 5 are fixed together with screws. Because the circuit board 5 is fixedly installed, the baffle 4 is also fixed, reliably restricting the Z-axis movement of the silicone pad and ensuring reliable connection between the nickel particles on the silicone pad 3 and the gold fingers on the circuit board 5. Second, the baffle 4 and circuit board 5 are first connected together and then assembled into the recessed area on the lower housing. This eliminates the separate assembly of the circuit board and baffle, preventing the baffle 4 from falling off during installation. The automotive electronic shifting mechanism described in this invention has a simple structure. After the baffle and circuit board are installed, the Z-axis limitation of the silicone pad is ensured, reducing the probability of unlocking failures. Furthermore, the baffle is fixed to the circuit board before being assembled into the lower housing, preventing it from falling off and improving overall performance.

[0025] The baffle 4 is fixedly connected to the circuit board 5 by screws. The baffle 4 and circuit board 5 are configured to snap into the groove 8. In this structure, the baffle and circuit board are fixedly connected, and installation is a single step. The fixed installation of the circuit board ensures the baffle's position is fixed. The baffle reliably limits the position of the silicone pad, preventing it from loosening and effectively ensuring reliable performance.

[0026] A silicone pad 3 is provided on the side of the baffle 4, and the silicone pad 3 is connected to the unlock button 2. In the above structure, when the unlock button is pressed, the unlock button acts on the silicone pad, and the nickel particles on the silicone pad 3 are reliably connected to the gold fingers on the circuit board 5, so as to reliably realize the unlocking function.

[0027] The circuit board 5 has one circuit board positioning hole 9 near the baffle 4 at one end, and another circuit board positioning hole 9 at the other end away from the baffle 4. The recessed portion 8 has one recessed portion positioning hole near the baffle 4 at one end, and another recessed portion positioning hole at the other end of the circuit board 5 away from the baffle 4. The circuit board 5 has a circuit board threaded hole 10 on each side near the baffle 4 at one end, and another on each side away from the baffle 4 at one end. The recessed portion 8 has a recessed portion threaded hole on each side near the baffle 4 at one end, and another on each side of the circuit board 5 away from the baffle 4 at one end. With this structure, when installing the circuit board 5, the positioning pins reliably achieve precise positioning of the circuit board in the recessed portion, and then the bolts reliably fix the circuit board 5.

[0028] The gear shifting mechanism body 6 includes a lower housing 1 and an upper housing. A groove 8 is disposed inside the lower housing 1, and the upper housing is fastened to the lower housing 1. In the above structure, the groove 8, the unlock button 2, the silicone pad 3, the baffle 4, and the circuit board 5 are all disposed on the lower housing. After the silicone pad 3, the baffle 4, and the circuit board 5 are installed in place, the upper housing and the lower housing are fastened together.

[0029] The circuit board 5 has a folded edge 11 on one side, and a baffle 4 fits against the folded edge 11. Screws pass through the folded edge 13 to connect the baffle 4. In this structure, the circuit board body is horizontal, and the folded edge is vertical, which facilitates the screws passing through the folded edge 11 to screw the baffle on. Furthermore, the baffle 4 is always fitted against the folded edge, effectively achieving a fixed connection between the baffle and the circuit board.

[0030] The automotive electronic gear shifting mechanism of this utility model features improvements to its partial structure. The shifting mechanism includes a shifting mechanism body 6, a baffle 4, a circuit board 5, and a positioning post 7. An unlock button 2 is provided on the shifting mechanism body 6. Pressing the unlock button unlocks the gear. A recessed portion 8 is provided on the shifting mechanism body 6. The baffle 4 is fixedly connected to the circuit board 5, possibly via screws. The circuit board 5 has a circuit board positioning hole 9 and a circuit board bolt hole 10. The recessed portion 8 has a recessed portion positioning hole and a recessed portion threaded hole. When installing the circuit board, the positioning post 7 passes through the circuit board positioning hole 9 and the recessed portion positioning hole to position the circuit board 5 within the recessed portion. Then, a bolt passes through the circuit board bolt hole 10 and the recessed portion threaded hole to fix the circuit board 5 within the recessed portion 8. The fixed connection between the baffle 4 and the circuit board 5 ensures the baffle 4 remains in a fixed position, reliably limiting the silicone pad 3 and preventing the silicone pad 3 from loosening after repeated pressing of the unlock button 2. Because the silicone pad 3 will not loosen, it effectively ensures a reliable connection between the nickel particles on the silicone pad 3 and the gold fingers on the circuit board 5, thus effectively ensuring the reliable performance of the shifting mechanism. This invention solves two problems: First, the baffle 4 and the circuit board 5 are fixed together with screws. Because the circuit board 5 is fixedly installed, the baffle 4 is also fixed, and the baffle 4 reliably restricts the Z-axis of the silicone pad, ensuring a reliable connection between the nickel particles on the silicone pad 3 and the gold fingers on the circuit board 5. Second, the baffle 4 and the circuit board 5 are first connected together, and then assembled into the groove 8 on the lower housing 1. This eliminates the possibility of the circuit board 5 and the baffle 4 being assembled separately, preventing the baffle 4 from falling off during installation.

[0031] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
