Description

Technical Field

[0001] This application relates to the field of sensors, and more particularly to a fast shift sensor. Background Technology

[0002] The gear shift mechanism is a key component of a vehicle's transmission system, primarily used for gear control. Its design and operation have a significant impact on vehicle performance and driving experience.

[0003] The utility model patent with announcement number CN223242035U proposes a quick shifting mechanism, including a pull rod and a sleeve; the sleeve has a hollow cavity, a retaining sleeve is fixed at the upper end of the sleeve, a mounting base is fixed on the outside of the sleeve, a circuit board is fixed on the mounting base, and a Hall element is provided on the circuit board; the pull rod passes through the retaining sleeve, and the lower end of the pull rod is inserted into the cavity and fixed with a magnet; the pull rod is provided with a spring reset assembly, which provides elastic force in the up and down direction, and resets the pull rod after the external force is removed.

[0004] In one of the aforementioned quick-shifting mechanisms, the elastic element is located between the upper and lower helical spring seats. The distance between the upper and lower helical spring seats is limited by the support part. However, the support part is sleeved on the elastic element, and the elastic element is squeezed and deformed during compression, which easily causes friction with the side wall of the support part, resulting in a reduced service life. Utility Model Content

[0005] To address the aforementioned issues, this application provides a fast gear shift sensor.

[0006] The fast shift sensor provided in this application adopts the following technical solution:

[0007] A quick-shift sensor includes a housing and a pull rod. The housing and pull rod are provided with a spring-loaded assembly for resetting the pull rod. The spring-loaded assembly includes an end cap fixedly connected to one end of the housing. The pull rod is located inside the housing and one end passes through the end cap. A helical compression spring is sleeved on the pull rod. A first impact piece and a second impact piece are fixedly connected to both ends of the helical compression spring, respectively. An annular groove is formed on the inner wall of the housing. The first impact piece is located within the annular groove and one sidewall is in contact with the end cap. An annular limiting groove is formed on the inner wall of the housing at the location of the helical compression spring. One sidewall of the second impact piece is in contact with one end sidewall of the annular limiting groove. A fixing block is fixedly connected to the pull rod and is in contact with the second impact piece. A protrusion is provided on the sidewall of the pull rod, and the protrusion is slidably disposed within the end cap, with one sidewall in contact with the first impact piece.

[0008] By adopting the above technical solution, during use, pulling the lever causes the fixed block to move, pushing the second impact piece to move in the annular limiting groove and approach the first impact piece, compressing the spiral spring. When released, the spiral spring rebounds and resets the lever. Alternatively, pushing the lever causes the protrusion to push the first impact piece to move in the annular groove and approach the second impact piece, compressing the spiral spring. During the compression process of the spiral spring, the annular limiting groove maintains a certain distance between the outer wall of the spiral spring and the inner wall of the outer shell, preventing deformation of the spiral spring during contraction and friction with the side wall of the outer shell. This minimizes the problem of elastic elements being squeezed and deformed during compression, which could easily cause friction with the side wall of the support and reduce service life.

[0009] Preferably, a magnet is fixedly connected to one end of the pull rod inside the housing, a rubber sleeve is fixedly connected to one side wall of the housing, a circuit board is installed on the side wall of the rubber sleeve near the housing, and a linear displacement sensor for detecting the displacement of the magnet is installed on the circuit board.

[0010] By adopting the above technical solution, the lever is connected to the pedal. When the driver presses or pulls the shift pedal, the lever moves. The movement of the lever moves the magnet. The linear displacement sensor converts the magnetic field displacement caused by the movement of the magnet into a signal output required by the whole vehicle to shift gears.

[0011] Preferably, the end of the housing away from the pull rod has a threaded hole for easy connection.

[0012] By adopting the above technical solution, the outer casing can be easily installed and fixed to external equipment through the threaded hole.

[0013] Preferably, the side wall of the pull rod away from the housing has an external thread, and a protective sleeve is fitted on the pull rod.

[0014] By adopting the above technical solution, the pull rod can be easily connected to the vehicle pedal through the external thread, and the external thread on the pull rod can be protected during storage through the protective sleeve.

[0015] Preferably, the diameter of the annular groove is larger than the diameter of the annular limiting groove.

[0016] By adopting the above technical solution, the first impact piece is prevented from slipping out of the annular groove and into the annular limiting groove when it moves in the annular groove.

[0017] Preferably, a sealing ring is provided between the end cap and the outer shell.

[0018] By adopting the above technical solution, the sealing ring increases the airtightness between the end cap and the outer shell, preventing debris, moisture, etc. from seeping in through the gap between the outer shell and the end cap.

[0019] Preferably, a certain gap is left between the first impact piece and the second impact piece and the outer shell.

[0020] By adopting the above technical solutions, the first and second impact plates are prevented from contacting the outer shell during movement, thereby reducing friction during operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application utilizes the cooperative arrangement of a first impact piece, a second impact piece, and an annular limiting groove. During use, pulling the lever moves the fixed block, pushing the second impact piece within the annular limiting groove, bringing it closer to the first impact piece and compressing the spiral spring. When released, the spiral spring rebounds, resetting the lever. Alternatively, pushing the lever causes the protrusion to push the first impact piece within the annular groove, bringing it closer to the second impact piece and compressing the spiral spring. During compression, the annular limiting groove maintains a certain distance between the outer wall of the spiral spring and the inner wall of the outer shell, preventing deformation during spring contraction and friction with the side wall of the outer shell. This minimizes the risk of deformation of the elastic element during compression, which could lead to friction with the side wall of the support and reduced service life.

[0023] 2. By connecting the lever to the pedal, when the driver presses or pulls the shift pedal, the lever moves, which in turn moves the magnet. The linear displacement sensor converts the magnetic field displacement caused by the magnet's movement into a signal output required by the vehicle to shift gears. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] Embodiment 1 of this application discloses a fast gear shift sensor.

[0031] Reference Figure 1 and Figure 2 A quick shift sensor includes a housing 1 and a pull rod 2. The housing 1 and the pull rod 2 are provided with a spring-loaded assembly for resetting the pull rod 2. The spring-loaded assembly includes an end cap 3, a helical compression spring 4, a first impact piece 5, a second impact piece 6, an annular groove 7, an annular limiting groove 8, a fixing block 9, and a protrusion 10.

[0032] One end of the end cap 3 is inserted into one end of the outer shell 1 and forms a threaded connection. The pull rod 2 is located inside the outer shell 1 and one end passes through the end cap 3. The spiral spring 4 is sleeved on the pull rod 2. The first impact piece 5 and the second impact piece 6 are sleeved on the pull rod 2 and are fixedly connected to both ends of the spiral spring 4, respectively. The annular groove 7 is opened on the inner wall of the outer shell 1. The first impact piece 5 is located in the annular groove 7 and one side wall is in contact with the end cap 3. The annular limiting groove 8 is opened on the inner wall of the outer shell 1 and is located at the spiral spring 4. One side wall of the second impact piece 6 is in contact with one end side wall of the annular limiting groove 8. The fixing block 9 is sleeved on the pull rod 2 and forms a fixed connection. The fixing block 9 is in contact with the second impact piece 6. The protrusion 10 is provided on the side wall of the pull rod 2. The protrusion 10 is slidably disposed in the end cap 3 and one side wall is in contact with the first impact piece 5.

[0033] Reference Figure 1 and Figure 2 A magnet 11 is fixedly connected to one end of the lever 2 located inside the housing 1. A rubber sleeve 12 is fixedly connected to one side wall of the housing 1. A circuit board 13 is installed on the side wall of the rubber sleeve 12 near the housing 1. A linear displacement sensor 14 for detecting the displacement of the magnet 11 is installed on the circuit board 13. By connecting the lever 2 to the pedal, when the driver presses or pulls the shift pedal, the lever 2 moves. The movement of the lever 2 causes the magnet 11 to move. The linear displacement sensor 14 converts the magnetic field displacement caused by the movement of the magnet 11 into a signal output required by the whole vehicle to shift gears.

[0034] Reference Figure 1 and Figure 2 The end of the outer casing 1 away from the pull rod 2 is provided with a threaded hole 15 for easy connection. The end of the outer casing 1 away from the pull rod 2 can also be provided as a threaded post. The threaded hole 15 facilitates the installation and fixation of the outer casing 1 to external equipment.

[0035] Reference Figure 2 The pull rod 2 has an external thread 16 on the side wall away from the outer casing 1, and a protective sleeve 17 is fitted on the pull rod 2. The external thread 16 facilitates the connection between the pull rod 2 and the vehicle pedal, while the protective sleeve 17 protects the external thread 16 on the pull rod 2 during storage.

[0036] Reference Figure 2 The diameter of the annular groove 7 is larger than the diameter of the annular limiting groove 8 to prevent the first impact piece 5 from sliding out of the annular groove 7 and into the annular limiting groove 8 when it moves in the annular groove 7.

[0037] Reference Figure 2 A sealing ring 18 is provided between the end cap 3 and the outer shell 1. The sealing ring 18 increases the sealing between the end cap 3 and the outer shell 1, preventing debris, moisture and other substances from seeping in through the gap between the outer shell 1 and the end cap 3.

[0038] Reference Figure 2 A certain gap is left between the first impact piece 5 and the second impact piece 6 and the outer shell 1 to prevent the first impact piece 5 and the second impact piece 6 from contacting the outer shell 1 when they move, thereby reducing friction during movement.

[0039] The implementation principle of a quick shift sensor in Embodiment 1 of this application is as follows: In use, the lever 2 is first connected to the pedal. When the driver presses or hooks the shift pedal, the lever 2 moves. The movement of the lever 2 causes the magnet 11 to move. The linear displacement sensor 14 converts the magnetic field displacement caused by the movement of the magnet 11 into a signal output required by the whole vehicle to shift gears. At the same time, when the lever 2 moves, it causes the fixing block 9 to move, pushing the second impact piece 6 to move in the annular limiting groove 8 and approach the first impact piece 5, so that the spiral spring 4 is compressed. When released, the spiral spring 4 rebounds and resets the lever 2, or the protrusion 10 pushes the first impact piece 5 to move in the annular groove 7 and approach the second impact piece 6, so that the spiral spring 4 is compressed. During the compression process of the spiral spring 4, the annular limiting groove 8 keeps a certain distance between the outer wall of the spiral spring 4 and the inner wall of the outer shell 1, preventing the spiral spring 4 from deforming when it contracts and rubbing against the side wall of the outer shell 1. This avoids the elastic element being squeezed and deformed during compression, which could easily cause friction with the side wall of the support and reduce its service life.

[0040] Example 2

[0041] The difference from Example 1 is that;

[0042] Reference Figure 3 and Figure 4 One end of the end cap 3 has an annular receiving groove 19, and multiple fixing rods 20 are provided in the annular receiving groove 19. One end of the fixing rod 20 is fixedly connected to a moving plate 21, and the other end of the fixing rod 20 passes through the annular receiving groove 19 and forms a sliding arrangement. One end of the outer shell 1 has multiple fixing holes 22 that are adapted to the fixing rods 20. An annular push block 23 is slidably arranged in the annular receiving groove 19. The end of the annular push block 23 near the moving plate 21 is set as a guide slope. One end of the end cap 3 has a cover plate 24. A threaded ring 25 is fixedly connected to one side wall of the cover plate 24. The threaded ring 25 is located in the annular receiving groove 19 and forms a threaded connection.

[0043] Springs 26 are fixedly connected to one side wall of the movable plate 21 on both sides of the fixed rod 20. The end of the spring 26 away from the movable plate 21 is fixedly connected to the side wall of the annular receiving groove 19. When the movable plate 21 is pushed to insert the fixed rod 20 into the fixed hole 22, the spring 26 is compressed. When the annular push block 23 is removed, the spring 26 rebounds, making it easy to move the fixed rod 20 out of the fixed hole 22 and remove the end cover 3 from the outer shell 1.

[0044] The implementation principle of Embodiment 2 of this application is as follows: By inserting the end cap 3 into the outer shell 1, the fixing rods 20 are aligned with the fixing holes 22 respectively. By inserting the annular push block 23 into the annular receiving groove 19, the guide slope of the annular push block 23 contacts the moving plate 21, and the moving plate 21 is squeezed and pushed, so that the moving plate 21 pushes the fixing rods 20 into the fixing holes 22. Then, by screwing the threaded ring 25 into the annular receiving groove 19, the threaded ring 25 abuts against the annular push block 23 to prevent the annular push block 23 from moving and to fix the moving plate 21. At the same time, when the threaded ring 25 rotates slightly, the annular push block 23 always remains in contact with the moving plate 21 to prevent the fixing rods 20 from moving out of the fixing holes 22, so that the end cap 3 is stably connected to the outer shell 1, avoiding the problem that the end cap 3 may rotate under the force, causing the end cap 3 to move and reducing the limiting effect.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
