Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive shifting mechanisms, and in particular to an automotive shifter. Background Technology
[0002] Cars are a common means of transportation in people's lives, and people's demands for car performance are getting higher and higher. Gear shift switches are also being used more and more, such as car gear shifters. The main task of a car gear shifter is to transmit power and change the gear ratio during power transmission to adjust or change the characteristics of the engine, while adapting to different driving requirements through gear changes.
[0003] In automotive gear shifters, the combination of a shift arm and a guide rail is a common structural design. For example, in the CN 219673259U automotive gear shifter structure, the shift arm is inserted into the shaft hole of the shift lever, and a guide rail and groove structure ensures vertical insertion guidance. This type of shift arm has significant drawbacks during movement: if the gap between the shift arm and the shaft hole wall is too small, the shift arm is prone to jamming, affecting the smoothness of shifting; if the gap is too large, the initial wobbling of the shift lever will be greater, reducing shifting accuracy and driving experience. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing an automotive gear shifter that improves the smoothness and stability of gear shifting.
[0005] The technical solution of this utility model is as follows: A car gear shifter includes a switch base and a gear shift handle pivotally connected to the switch base. The switch base has a track, and the gear shift handle has a sliding hole with an open lower end. A gear position pin is movably inserted into the sliding hole. The gear position pin abuts against the track under the action of an elastic element. The upper end of the gear position pin forms an interference fit with the inner wall of the sliding hole, and the upper end of the gear position pin has a slot along the vertical direction with an open upper end. An elastic arm is provided on the outer periphery of the lower end of the gear position pin, and the elastic arm abuts against the inner wall of the sliding hole.
[0006] By adopting the above technical solution, the upper end of the gear shift pin forms an interference fit with the inner wall of the sliding hole, which enhances the stability of the gear shift pin in the sliding hole of the gear shift handle and improves the shaking problem; at the same time, the setting of the slot hole allows the upper end of the gear shift pin to undergo extrusion deformation during gear shifting, avoiding gear shifting jamming and improving the smoothness of gear shifting operation.
[0007] In addition, the elastic arm on the outer periphery of the lower end of the gear shift pin abuts against the inner wall of the sliding hole. This design not only increases the stability of the gear shift pin in the sliding hole, but also allows the elastic deformation capability of the elastic arm to adapt to the shifting needs under different driving conditions, avoiding shifting jamming.
[0008] A further feature of this invention is that the stop pin has a hollow hole with an opening at the top, the slot is connected to the outer periphery of the hollow hole, and the hollow hole allows an elastic element to be inserted.
[0009] With the above-described further design, the shift pin has a hollow hole with an open top. This design not only facilitates the insertion of the elastic element but also makes the shift pin more structurally flexible. The slot is connected to the outer periphery of the hollow hole. This connection design allows the upper end of the shift pin to undergo compression deformation during shifting, further improving the smoothness of shifting.
[0010] A further feature of this invention is that the upper end of the stop pin has a protruding abutment portion on its outer periphery, wherein the abutment portion forms an interference fit with the sliding hole.
[0011] With the further configuration described above, the abutment portion enhances the friction between the gear shift pin and the sliding hole, thereby improving the stability of the gear shift pin during gear shifting. Simultaneously, the interference fit between the abutment portion and the sliding hole effectively prevents the gear shift pin from shaking or falling off during gear shifting, further ensuring the accuracy and reliability of gear shifting.
[0012] A further feature of this invention is that the lower end of the stop pin is provided with at least one pair of elastic arms, the inner end of each elastic arm is integrally connected to the stop pin, and the outer end is provided with a clamp. The clamps of the pair of elastic arms cooperate to form a clamping hole. A limiting block is provided on the inner wall of the sliding hole. The limiting block is located in the clamping hole and abuts against the clamps of the pair of elastic arms.
[0013] With the further modifications described above, the cooperation between the chuck and the limiting block provides stable support during gear shifting, making the shifting operation smoother and more reliable. The design of the elastic arm allows the gear shift pin to better adapt to minute changes in the inner wall of the sliding hole during gear shifting, enhancing the flexibility and adaptability of gear shifting.
[0014] A further feature of this invention is that the limiting block extends vertically, and the limiting block and the clamping hole form a vertically movable guiding fit.
[0015] With the aforementioned further design, the limiting block extends vertically and engages with the clamping hole, ensuring smoother movement of the shift pin within the sliding hole and preventing it from deviating from the predetermined path. This design not only improves the accuracy of gear shifting but also further enhances the stability and reliability of the shifting operation.
[0016] A further feature of this invention is that the clamps of the pair of elastic arms bend towards each other.
[0017] With the further design described above, the clamps of the pair of elastic arms bend closer together, allowing for more effective engagement with the limit block and enhancing clamping stability and force. During gear shifting, the clamps fit better against the limit block, reducing wobbling and resulting in more precise and smooth shifting. Furthermore, this design ensures the gear shifter maintains good working condition over long-term use, extending its service life.
[0018] A further feature of this invention is that the clamps of the pair of elastic arms are provided with a contacting plane, which forms a contacting engagement with the limiting block.
[0019] With the above-mentioned further design, the presence of the contact surface increases the contact area between the chuck and the limiting block, thereby enhancing the uniformity of force distribution on the shifter during shifting and reducing wear and malfunctions caused by uneven force distribution.
[0020] A further feature of this invention is that multiple pairs of elastic arms are evenly distributed circumferentially around the lower end of the stop pin.
[0021] With the further configuration described above, multiple pairs of elastic arms are evenly distributed circumferentially around the lower end of the gear shift pin. This layout not only improves the symmetry of the gear shifter structure but also enhances the overall stability of the gear shifter during gear shifting. Each pair of elastic arms can evenly distribute the force during gear shifting, effectively preventing excessive wear or damage to individual elastic arms due to force concentration.
[0022] A further feature of this invention is that the sliding hole has a square hole structure, and four limiting blocks are provided and distributed at the corners of the sliding hole.
[0023] With the above-mentioned further design, the sliding hole is designed as a square hole structure, and the limiting blocks are located at each corner of the sliding hole. This design not only enhances the stability of the shifter structure but also improves the accuracy and reliability of shifting. The square hole structure limits the offset of the shift pin during shifting, while the four limiting blocks can evenly bear the pressure from the shift pin, effectively preventing shaking and misalignment during shifting. This design not only extends the service life of the shifter but also provides users with a smoother and more stable shifting experience.
[0024] A further feature of this invention is that the limiting block has a triangular block structure.
[0025] With the above-mentioned further design, the limiting block is designed as a triangular block structure. This shape not only enhances the strength of the limiting block but also improves its fit with the edges of the sliding hole. The triangular block structure can better resist the pressure from the shift pin, reducing deformation during gear shifting, thereby further improving the stability and reliability of the gear shifter. In addition, the triangular block structure is easier to process and install, reducing production costs and improving production efficiency. This design not only optimizes the performance of the gear shifter but also provides users with a more reliable and durable gear shifter product. Attached Figure Description

[0030] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0031] like Figure 1-4As shown, this utility model discloses a car gear shifter, including a switch base 1 and a gear shift handle 2 pivotally connected to the switch base. The gear shift handle 2 is pivotally connected to the switch base via a rotating shaft, allowing the gear shift handle 2 to be moved back and forth. The switch base 1 has a rail 3 inside, which is fixed or integrally set in the switch base 1. The gear shift handle 2 has a sliding hole 21 with an opening at the lower end. A gear position pin 4 is movably inserted into the sliding hole 21, and the gear position pin 4 can move up and down within the sliding hole 21. Under the action of an elastic element 5, the gear position pin 4 abuts against the rail 3, and the lower end of the gear position pin 4 abuts against the rail 3. The upper end of the stop pin 4 abuts against the elastic element 5, which is a spring. The upper end of the stop pin 4 forms an interference fit with the inner wall of the sliding hole 21, and the upper end of the stop pin 4 has a slot 41 vertically. The upper end of the slot 41 is open. The "vertical" refers to the up-down direction. The stop pin 4 has a hollow hole 43 with an open upper end. The stop pin 4 has a cylindrical structure. The slot 41 is connected to the outer periphery of the hollow hole 43. The hollow hole 43 can accommodate the elastic element 5. The outer periphery of the upper end of the stop pin 4 has an integrally protruding abutment part 44, which forms an interference fit with the sliding hole 21. The slot has a "V" shaped hole structure, which gradually increases in size from bottom to top. At least one slot is provided on the circumference of the upper end of the stop pin 4.
[0032] The lower end of the stop pin 4 has an elastic arm 42 on its outer periphery, which abuts against the inner wall of the sliding hole 21. At least one pair of elastic arms 42 are provided on the lower end of the stop pin 4. The inner end of each elastic arm 42 is integrally connected to the stop pin 4, and the outer end has a clamp 421. The clamps of the pair of elastic arms cooperate to form a clamping hole 422. A limiting block 211 is provided on the inner wall of the sliding hole 21. The limiting block 211 is located within the clamping hole 422 and abuts against the clamps 421 of the pair of elastic arms. The limiting block 211 extends vertically and forms a vertically movable guide cooperation with the clamping hole 422. The clamps 421 of the pair of elastic arms 42 bend towards each other. The clamps 421 of the pair of elastic arms have a contact surface 4211, which forms a contact cooperation with the limiting block 211. Multiple pairs of elastic arms 42 are evenly distributed circumferentially on the lower end of the stop pin 4. The sliding hole 21 has a square hole structure, and four limiting blocks 211 are provided and distributed at the corners of the sliding hole 21. The limiting blocks 211 have a triangular block structure. The sliding hole 21 can also be circular or other shapes.
[0033] The switch base 1 of this invention serves as the base of the entire gear shifter, securely mounted on the vehicle and providing support for the gear shift lever 2. The gear shift lever 2 engages with the switch base 1 via a pivot mechanism, allowing the driver to easily shift gears. The track 3 is located inside the switch base 1, providing a precise movement path for the gear position pin 4, ensuring the accuracy and stability of gear shifting. The gear position pin 4 is a key component of the gear shifter; it is movably inserted into the sliding hole 21 of the gear shift lever 2 and, under the action of the elastic element 5, tightly abuts against the track 3. This design allows the gear position pin 4 to move smoothly within the track 3 during gear shifting while maintaining a stable contact force.
[0034] The upper end of the gear shift pin 4 forms an interference fit with the inner wall of the sliding hole 21, which enhances the stability of the gear shift pin 4 in the sliding hole of the gear shift handle and improves the shaking problem. At the same time, the setting of the slot 41 makes it easy for the upper end of the gear shift pin 4 to be squeezed and deformed when shifting gears, avoiding gear shifting jamming and improving the smoothness of gear shifting operation.
[0035] In addition, a pair of elastic arms on the outer periphery of the lower end of the gear shift pin abut against a limiting block on the inner wall of the sliding hole. This design not only increases the stability of the gear shift pin 4 in the sliding hole 21, but also allows the elastic deformation capability of the elastic arms 42 to adapt to the shifting needs under different driving conditions, avoiding shifting jamming.
