Description

Technical Field

[0001] The utility model relates to the technical field of gear shifters, in particular to a P gear short-distance unlocking and locking solenoid valve structure. Background Art

[0002] With the improvement of automobile comfort and safety, major automobile OEMs are pursuing smaller shift angles based on ergonomic simulation. At the same time, to increase the safety of the entire vehicle, the shifter has an N gear lock function. As a result, the PR shift stroke is short and the structural space is limited, causing the solenoid valve spindle to not fully return from P gear to R gear, making it impossible to achieve the purpose of unlocking. Summary of the invention

[0003] In view of the problems existing in the above-mentioned prior art, the purpose of the present application is to provide a P gear short-distance unlocking and locking solenoid valve structure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A P-position short-distance unlocking and locking solenoid valve structure comprises a shift lever and a solenoid valve, the solenoid valve comprises a valve body and a solenoid valve main shaft, the shift lever is fixed with a pin shaft, a locking arm is rotatably mounted on the pin shaft, the locking arm is provided with a locking groove that can be clamped with the solenoid valve main shaft; a compression spring is mounted on the pin shaft, one end of the compression spring is fixedly connected to the shift lever, and the other end of the compression spring is pressed against the locking arm.

[0006] Wherein, the end of the locking arm is provided with an R-arc surface.

[0007] Wherein, the shift lever is provided with a bracket for lifting the locking arm.

[0008] Wherein, the pin shaft is fixedly installed in the bracket.

[0009] Wherein, a yielding inclined surface is arranged on one side of the locking groove close to the pin shaft.

[0010] In summary, the P-position short-distance unlocking and locking solenoid valve structure improves the problem that the P-position cannot be designed with an unlocking and locking structure when the shifter has a short shifting stroke from P-position to R-position and a small space arrangement. It improves the space utilization rate in the shifter design process and provides a more efficient P-position unlocking and locking solution for OEMs. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of a P gear short-distance unlocking and locking solenoid valve structure described in the utility model. DETAILED DESCRIPTION

[0012] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0013] like Figure 1 As shown, a P-position short-distance unlocking and locking solenoid valve structure includes a shift lever 1 and a solenoid valve 4, wherein the solenoid valve 4 includes a valve body 6 and a solenoid valve main shaft, the shift lever 1 is fixed with a pin shaft 2, and a locking arm 5 is rotatably mounted on the pin shaft 2, and the locking arm 5 is provided with a locking groove that can be clamped with the main shaft of the solenoid valve 4; a compression spring 3 is installed on the pin shaft 2, one end of the compression spring 3 is fixedly connected to the shift lever 1, and the other end of the compression spring 3 is pressed tightly on the locking arm 5.

[0014] 1. Unlocking from P gear to R gear:

[0015] P gear solenoid valve status:

[0016] The locking arm 5 is provided with a locking groove, that is, the locking arm 5 is arranged in a hook-shaped structure, and a rotatable part is formed by the pin shaft 2. Under the action of the compression spring 3, the main shaft of the solenoid valve 4 is limited (the bracket groove on the shift lever serves as a limiting structure to prevent the locking arm from colliding with the main shaft of the solenoid valve), thereby achieving the purpose of locking the solenoid valve in the P gear.

[0017] After the P gear solenoid valve is activated, the PR gear 2 / 3 stroke position status:

[0018] The locking arm 5 has left the position where the solenoid valve main shaft is reset. At this time, the solenoid valve is powered off and returns to its original position after the unlocking delay time.

[0019] R gear solenoid valve status:

[0020] The locking arm 5 has completely disengaged from the main shaft of the solenoid valve 4, reaching the R gear position. At the same time, the main shaft of the solenoid valve has achieved the purpose of fully returning to its original position.

[0021] The entire PR shift stroke is controlled within 8.5mm.

[0022] 2. Locking from R gear to P gear:

[0023] At this time, the solenoid valve main shaft is in the power-off return state, and the R-arc surface at the front end of the locking arm 5 is in contact with the solenoid valve main shaft. During the gear shifting process, the R-arc surface of the locking arm 5 slides on the solenoid valve main shaft. At the same time, the locking arm 5 will be lifted around the pin shaft 2 under the condition of force, and after a short stroke, it will be hung on the solenoid valve main shaft.

[0024] This application improves the structure that the P gear position cannot be designed to unlock and lock when the shift stroke from P gear to R gear is short and the space is small. It improves the space utilization rate in the design process of the shifter and provides a more efficient P gear solution for the OEM.

[0025] When the user needs to unlock the P gear from the P gear to the R gear, the user steps on the brake to transmit the unlocking signal to the solenoid valve 4, so that the main shaft of the solenoid valve 4 is stimulated to retreat into the valve body 5. At this time, the user manipulates the shift lever 1 to pull out the P gear (without considering the mechanical unlocking of the hand ball). At the same time, the shift lever 1 drives the locking arm 5 to shift out of the P gear, realizing the function of unlocking the P gear solenoid valve.

[0026] When the user needs to shift from R to P gear and lock it in R gear, he only needs to operate the shift lever 1 (without considering the mechanical unlocking of the hand ball) to directly shift into P gear, thereby realizing the function of locking the P gear.

[0027] During specific implementation, the end of the locking arm is provided with an R-arc surface to avoid hard collision with the main shaft of the solenoid valve; the shift lever is provided with a bracket for lifting the locking arm, which is convenient for supporting and limiting the locking arm; the pin shaft is fixedly installed in the bracket to facilitate the installation of the locking arm; the locking groove is provided with a yielding inclined surface on the side close to the pin shaft to provide better space.

[0028] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
