Description

Technical Field

[0001] This invention relates to the field of shifting structure technology, and more specifically, to a shifting core with a lever locking structure. Background Technology

[0002] Traditional shift core control lever structures include an actuator assembly and a shift core assembly. The control lever is located in the shift core assembly. When the control lever automatically rises with the shift core assembly, the control lever needs to be locked. However, existing ones do not have a locking structure for the control lever. Summary of the Invention

[0003] The purpose of this invention is to provide a shifting core with a joystick locking structure to solve the problem of automatic locking when the joystick is raised in the prior art.

[0004] To achieve the above objectives, the present invention provides a shift core with a lever locking structure, comprising:

[0005] An actuator assembly, the actuator assembly including a first housing, the first housing having a mounting hole, a guide groove and a first connecting groove on one outer surface;

[0006] A shift core assembly includes a control lever, a locking slider, and a second housing. The second housing is rotatably mounted in a mounting hole, and the control lever is rotatably mounted inside the second housing. The second housing has a second connecting groove, and the control lever extends a connecting rod from the second connecting groove. The actuator assembly has a connecting hole corresponding to the first connecting groove, and the connecting hole connects to the connecting rod. Rotating the control lever transmits rotational motion to the actuator assembly through the connecting hole and the connecting rod, causing the actuator assembly to generate a shift signal. The second housing has a guide rail and a sliding groove. The control lever has a locking protrusion, and the locking slider is slidably mounted on the guide rail. The locking slider has a column and a locking groove, and the locking groove cooperates with the locking protrusion to lock the control lever. The vertical rod extends from the sliding groove into the guide groove. The rod slides within the guide groove as the second housing rotates. The lower end of the control lever is provided with an elastic reset member. A reset surface is provided within the second housing to cooperate with the elastic reset member. When the elastic reset member is at the lowest point of the reset surface, the control lever is reset and the locking slider is aligned with the locking groove. The guide groove is an arc-shaped groove, and the center of the guide groove coincides with the center of the mounting hole. The guide groove includes a locking section and a movable section. The radius of the locking section is larger than the radius of the movable section. When the rod slides into the locking section, the locking slider slides up the guide rail, thereby placing the locking protrusion in the locking groove to lock the control lever. When the rod slides into the movable section, the locking slider slides down the guide rail and releases the locking control lever.

[0007] Optionally, an arc-shaped transition connection is used between the locking section and the moving section.

[0008] Optionally, the length of the movable trajectory of the column within the guide rail is greater than or equal to the radius difference between the locking section and the moving section.

[0009] Optionally, the length of the movable trajectory of the column in the sliding groove is greater than or equal to the radius difference between the locking section and the moving section.

[0010] Optionally, the reset surface is a symmetrically arranged inclined surface or a circular arc surface.

[0011] Optionally, the control lever includes a reset groove, the elastic reset member is installed in the reset groove, the elastic reset member includes a reset rod and a spring, one side of the spring abuts against the bottom surface of the reset groove, and the other side abuts against the reset rod, the reset rod includes a round head extending out of the reset groove, the round head abutting against the reset surface.

[0012] Optionally, the actuator assembly further includes a rotating ring, and the connection hole is formed by extending outward from the rotating ring.

[0013] Optionally, the outer wall of the rotating ring is provided with a gear portion.

[0014] As described above, applying the technical solution of this invention, the present invention provides a shift core with a lever locking structure. The shift core assembly is rotatably mounted on the actuator assembly. The lever is disposed inside the shift core assembly. When the shift core assembly is rotated until the column slides into the locking section, the locking slider automatically slides upward along the guide rail under the constraint of the guide rail. After sliding upward, the locking slider can cooperate with the locking protrusion on the lever to form a limit, thereby locking the lever. When the shift core assembly is rotated until the column slides into the moving section, the locking slider automatically slides downward along the guide rail under the constraint of the guide rail. The sliding block, after sliding down, can disengage from the locking protrusion, thereby unlocking the lever. Therefore, the above structure allows the lever to automatically lock when it rises with the shift core assembly and automatically unlock when it falls. After unlocking during the falling action, the lever can be rotated. The rotational motion is transmitted to the actuator assembly through the connection structure between the lever and the actuator assembly. The actuator assembly is equipped with an angle sensor, which identifies the rotational motion transmitted to the actuator assembly and generates a corresponding shift signal based on the rotational motion.

[0024] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention will be presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a deep understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description.

[0025] like Figures 1 to 7 The shift core shown includes a lever locking structure, comprising:

[0026] Actuator assembly 1, the actuator assembly 1 includes a first housing 11, and a mounting hole 111 and a guide groove 112 are provided on one outer surface of the first housing 11;

[0027] The shift core assembly 2 includes a control lever 21, a locking slider 22, and a second housing 23. The second housing 23 is rotatably mounted in a mounting hole 111. The control lever 21 is mounted inside the second housing 23. The second housing 23 has a guide rail 231 and a sliding groove 232. The control lever 21 has a locking protrusion 212. The locking slider 22 is slidably mounted on the guide rail 231. The locking slider 22 has a column 221. The column 221 extends from the sliding groove 232 into a guide groove 112. The column 221 slides within the guide groove 112 as the second housing 23 rotates. The guide groove 112 includes a locking section 1122 and a moving section 1121. Figure 2 As shown, the guide groove 112 is an arc-shaped groove, and the center of the guide groove 112 coincides with the center of the mounting hole 111. The radius of the locking section 1122 is larger than the radius of the movable section 1121. That is, the guide groove 112 is an arc-shaped groove formed by connecting multiple arc-shaped segments. The sliding trajectory of the locking slider 22 in the second housing 23 is restricted by the guide rail 231 and the sliding groove 232, so that the locking slider 22 can only slide up and down along the guide rail 231 or along the sliding groove 232. The length of the movable trajectory of the column 221 in the guide rail 231 is greater than or equal to the length of the locking section 1122 and the movable section 1121. The radius difference of 121, or in other words, the length of the movable trajectory of the column 221 in the sliding groove 232 is greater than or equal to the radius difference between the locking section 1122 and the moving section 1121. The column 221 slides into the locking section 1122, causing the locking slider 22 to slide up along the guide rail 231 and cooperate with the locking protrusion 212 to lock the control lever 21. The column 221 slides into the moving section 1121, causing the locking slider 22 to slide down along the guide rail 231 and release the locking control lever 21. Thus, the control lever 21 can automatically lock when it rises with the shift core assembly 2 and automatically unlock when it falls.

[0028] like Figure 2 As shown, the locking section 1122 and the movable section 1121 are connected by an arc-shaped transition, and the column 221 is also cylindrical, which facilitates the sliding of the column 221 in the guide groove 112 and makes the sliding transition between the locking section 1122 and the movable section 1121 smoother.

[0029] like Figure 4As shown, the locking slider 22 is provided with a locking groove 222. The locking groove 222 cooperates with the locking protrusion 212 to lock the operating lever 21. When the locking slider 22 slides up, the locking protrusion 212 is housed in the locking groove 222, thereby locking the position of the operating lever 21 and preventing the operating lever 21 from being rotated.

[0030] like Figure 5 and Figure 6 As shown, the control lever 21 is rotatably mounted in the second housing 23. The lower end of the control lever 21 is provided with an elastic reset member 211. The second housing 23 is provided with a reset surface 233 in cooperation with the elastic reset member 211. When the elastic reset member 211 is at the lowest point of the reset surface 233, the locking slider 22 is positioned opposite to the locking groove 222.

[0031] This embodiment provides a more preferred solution, wherein the reset surface 233 is a symmetrically arranged inclined surface or arc surface.

[0032] like Figure 5 As shown, the control lever 21 includes a reset groove 213, and the elastic reset member 211 is installed in the reset groove 213. The elastic reset member 211 includes a reset rod 2111 and a spring 2112. One side of the spring 2112 presses against the bottom surface of the reset groove 213, and the other side presses against the reset rod 2111. The reset rod 2111 includes a round head 21111 extending out of the reset groove 213, and the round head 21111 presses against the reset surface 233.

[0033] The reset structure allows the joystick 21 to automatically reset after completing the operation, and its reset position can automatically cooperate with the locking structure of the locking slider 22 to automatically lock the joystick 21.

[0034] In summary, this application provides a locking structure for a shift core control lever 21. The shift core assembly 2 is rotatably mounted on the actuator assembly 1. The control lever 21 is located inside the shift core assembly 2. When the shift core assembly 2 is rotated so that the column 221 slides into the locking section 1122, the locking slider 22 automatically slides upward along the guide rail 231 under the constraint of the guide rail 231. After sliding upward, the locking slider 22 can cooperate with the locking protrusion 212 on the control lever 21 to form a limit, thereby locking the control lever 21. When the shift core assembly 2 is rotated so that the column 221 slides into the moving section 1121, the locking slider 22 automatically slides downward along the guide rail 231 under the constraint of the guide rail 231. After sliding downward, the locking slider 22 can release the cooperation with the locking protrusion 212, thereby unlocking the control lever 21. Therefore, the above structure enables the control lever 21 to automatically lock when it rises with the shift core assembly 2 and automatically unlock when it falls.

[0035] like Figures 1 to 7 As shown, a first connecting groove 113 is also provided on one outer surface of the first housing 11. The first connecting groove 113, the mounting hole 111, and the guide groove 112 are all located on the same outer surface of the first housing 11. A second connecting groove 234 is provided on the second housing 23. The control lever 21 extends a connecting rod 214 from the second connecting groove 234. The actuator assembly 1 is provided with a connecting hole 121 at the position corresponding to the first connecting groove 113. The position of the second connecting groove 234 corresponds to the position of the first connecting groove 113, so that the connecting hole 121 can be connected to the connecting rod 214. Rotating the control lever 21 transmits the rotational action to the actuator assembly 1 through the connecting hole 121 and the connecting rod 214, so that the actuator assembly 1 generates a shift signal.

[0036] like Figure 7 As shown, the actuator assembly 1 also includes a rotating ring 12, and the connecting hole 121 is formed by extending outward from the rotating ring 12. An angle sensing device is provided inside the actuator assembly 1. The angle sensing device identifies the rotational action transmitted to the rotating ring 12 and generates a corresponding shift signal based on the rotational action.

[0037] This embodiment provides a more preferred solution, wherein the outer wall of the rotating ring 12 is provided with a gear part 122, and the rotation action of the rotating ring 12 can be transmitted through the gear part 122 and amplified by other gears (i.e., the rotation angle is amplified), so that the angle sensing device can more easily identify and generate a corresponding shift signal based on the rotation action.

[0038] In summary, the embodiments provided above are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
