Description

Technical Field

[0001] The present invention relates to the technical field of vehicle engineering, and in particular to an H-speed sequential gear switching device. Background Art

[0002] A Chinese invention patent application with application number 202110559605.4, entitled "A Vehicle Shifting Device with High Reliability," discloses a shifting device that can switch between H gear and sequential gear. A faceplate is provided on a fixed seat, and the faceplate is provided with an integrated gear slot that can be used for both H gear and sequential gear. The gear lever slides with the integrated gear slot via a support rod. A first positioning member is provided on the fixed seat, and the first positioning member cooperates with the positioning platform of the rotating seat to fix the rotating seat. The gear lever can only swing in one direction, thereby achieving switching from H gear mode to sequential gear mode. This patent uses a universal faceplate to switch from H gear mode to sequential gear mode by limiting the rotation of the gear lever and the gear lever. The advantages of this gear mode switching method are simple structural design, convenient disassembly and assembly, and easy repair, maintenance, and replacement of components. However, after frequent mode switching and long-term use, the gear shifting structure, faceplate structure, and gear mode switching structure are severely worn, which not only affects the gear shifting accuracy, smoothness, and operating feel, but also has high repair and replacement costs for components. Summary of the Invention

[0006] The base is provided with an H-grade faceplate;

[0007] The H-gear faceplate is provided with a through hole, the directional block is movably embedded in the through hole, and the directional block is provided with a sequence gear directional groove;

[0008] The elastic member is connected to the base and the orientation block respectively;

[0009] The pressing piece abuts against the orientation block.

[0010] Furthermore, the orientation block is slidably arranged in the through hole along an axis, the orientation block is provided with a guide column along a direction parallel to the axis, and the base is provided with a guide hole plugged with the guide column.

[0011] Furthermore, the elastic member is arranged in the guide hole, and the elastic member is connected to the base and the guide column respectively.

[0012] Furthermore, the orientation block is provided with a support column, and the pressing member abuts against a free end of the support column.

[0013] Furthermore, the number of the support columns is two, the number of the pressing members is two groups, and the free ends of the support columns are provided with supporting spherical surfaces that abut against the pressing members.

[0014] Furthermore, the orienting block is provided with a limiting platform, and the limiting platform is clamped with the base.

[0015] Furthermore, the middle portion of the pressing member is rotatably connected to the base, and one end of the pressing member abuts against the directional block.

The raising and lowering of the positioning block in the H-gear disc is controlled by a pressing member and an elastic member. One situation is: when the pressing member does not apply force to the positioning block, the positioning block extends from the through hole of the H-gear disc under the elastic force of the elastic member, and the gear engagement mode is the sequential gear mode. When the pressing member applies force to the positioning block, the positioning block retracts into the through hole of the H-gear disc under the pressing action, and the H-gear disc cooperates with the gear lever, and the gear engagement mode is the H-gear mode. Another situation is that when the pressing member does not apply force to the positioning block, the positioning block is hidden in the through hole of the H-gear disc under the elastic force of the elastic member. At this time, the gear mode is the H-gear mode.

[0028] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0029] The present invention provides an H-speed sequential gear switching device, which is applied to a vehicle gear shifting device.

[0030] Please refer to Figures 1 to 6 , an H-speed sequential gear switching device, comprising a base 1, a pressing member 2, a directional block 3 and an elastic member 4;

[0031] The pressing member 2 is movably arranged on the base 1;

[0032] The base 1 is provided with an H-grade faceplate 11;

[0033] The H-gear faceplate 11 is provided with a through hole 12, and the orientation block 3 is movably embedded in the through hole 12. The orientation block 3 is provided with a sequence gear orientation slot 31;

[0034] The elastic member 4 is connected to the base 1 and the orientation block 3 respectively;

[0035] The pressing member 2 abuts against the orientation block 3 .

[0036] As can be seen from the above description, the present invention provides an H-shift sequential shifting device. Based on an H-shift faceplate 11 disposed on a base 1, a directional block 3 is designed to be raised and lowered within the H-shift faceplate 11. The directional block 3 includes a sequential shift directional slot 31, which restricts the movement of the shift lever in one direction, acting as a shift position slot for the sequential shift. The raising and lowering of the directional block within the H-shift faceplate 11 is controlled by a pressing member 2 and an elastic member 4. In one embodiment, when the pressing member 2 does not apply force to the directional block, the directional block extends from the through hole 12 of the H-shift faceplate 11 under the elastic force of the elastic member 4, and the shift mode is the sequential shift mode. When the pressing member 2 applies force to the directional block, the directional block retracts into the through hole 12 of the H-shift faceplate 11 under the pressure, and the H-shift faceplate 11 cooperates with the shift lever, and the shift mode is the H-shift mode. Another situation is that when the pressing member 2 does not apply force to the positioning block, the positioning block is hidden in the through hole 12 of the H-gear disc 11 under the elastic force of the elastic member 4. At this time, the gear mode is the H-gear mode. When the pressing member 2 applies force to the positioning block, the positioning block extends from the through hole 12 of the H-gear disc 11 under the action of the pressing force. At this time, the sequential gear directional groove 31 cooperates with the gear lever, and the gear mode is the sequential gear mode. The above two situations need to be flexibly selected according to the structural layout of the gear shifting device. The H-gear sequential gear switching device provided by the present invention changes the universal faceplate into a split faceplate, and selects and uses the corresponding gear shifting groove form in different gear shifting modes. Compared with the traditional method of using fasteners to limit the rotation of the gear shifting mechanism to achieve gear shifting mode switching, even if the gear shifter frequently switches modes or is used for a long time, it will not cause serious wear of the gear shifting structure and the faceplate structure, thereby ensuring the gear shifting accuracy, smoothness and operating feel, and saving the cost of repairing and replacing components.

[0037] In an optional embodiment, the orientation block 3 is slidably arranged in the through hole 12 along an axis, the orientation block 3 is provided with a guide column 32 along a direction parallel to the axis, and the base 1 is provided with a guide hole 13 that is plugged into the guide column 32.

[0038] As can be seen from the above description, the guide block 3 is guided and positioned by the cooperation between the guide column 32 and the guide hole 13, thereby ensuring the stable movement of the gear shifting component, thereby improving the gear shifting accuracy and reducing wear.

[0039] In an optional embodiment, the elastic member 4 is disposed in the guide hole 13 , and the elastic member 4 is connected to the base 1 and the guide column 32 , respectively.

[0040] As can be seen from the above description, the elastic member 4 is received in the guide hole 13 and sleeved outside the guide column 32, saving space. The elastic member 4 applies a pulling / supporting force to the guide column 32, causing the positioning block to translate relative to the base 1.

[0041] In an optional embodiment, the orientation block 3 is provided with a support column 33 , and the pressing member 2 abuts against a free end of the support column 33 .

[0042] As can be seen from the above description, the pressing member 2 applies force to the support column 33 , thereby driving the positioning block to move relative to the base 1 , and controlling the positioning groove to expose or retract the through hole 12 .

[0043] In an optional embodiment, the number of the support columns 33 is two, the number of the pressing members 2 is two groups, and the free ends of the support columns 33 are provided with supporting spherical surfaces that abut against the pressing members 2 .

[0044] From the above description, it can be seen that there are two support columns 33 and two pressing parts 2, which is beneficial to improving the movement accuracy and stability of the positioning block. The design of the spherical support pressing part 2 can improve the response speed of the gear mode switching, improve the efficiency of the gear mode switching, facilitate the transmission of force, and reduce component wear.

[0045] In an optional embodiment, the orientation block 3 is provided with a limiting platform 34 , and the limiting platform 34 is engaged with the base 1 .

[0046] As can be seen from the above description, the limit platform 34 limits the orientation block 3, controls the height of the positioning block extending from the through hole 12 of the H-speed disc 11 under the elastic force of the elastic member 4, or prevents the pressing member 2 from overpressing the orientation block 3.

[0047] In an optional embodiment, the middle portion of the pressing member 2 is rotatably connected to the base 1 , and one end of the pressing member 2 abuts against the orientation block 3 .

[0048] As can be seen from the above description, the pressing member 2 can be installed on the base 1 according to the lever principle, which makes it easier to switch gear modes and saves effort and improves efficiency.

[0049] In an optional embodiment, a cam 5 is further included. The cam 5 is rotatably disposed on the base 1 , and the cam 5 abuts against the pressing member 2 .

[0050] From the above description, it can be seen that the cam 5 is used to press against the pressing member 2. When the high surface of the cam 5 abuts against the pressing member 2, the pressing member 2 applies a force to the directional block 3. When the low surface of the cam 5 abuts against the pressing member 2, the pressing member 2 does not apply a force to the directional block 3. Rotating the cam 5 can switch whether the cam 5 applies a force to the directional block 3, thereby switching the gear mode.

[0051] In an optional embodiment, a push rod 6 is further included, and the number of the pressing members 2 is two groups. The two ends of the push rod 6 are respectively connected to the two groups of pressing members 2, and the middle part of the push rod 6 abuts against the cam 5. The push rod 6 is perpendicular to the rotation axis of the cam 5.

[0052] From the above description, it can be seen that when there are two groups of pressing members 2, in order to ensure the consistency of the movement of the two groups of pressing members 2 and to improve the efficiency and accuracy of the gear mode switching, the two pressing members 2 are connected by a push rod 6, and the push rod 6 is pressed against the side wall of the cam 5. When the cam 5 is rotated, the push rod 6 is lifted or lowered, thereby switching the gear mode.

[0053] In an optional embodiment, a knob 7 is further included. The knob 7 is rotatably disposed on the base 1 , and the knob 7 is coaxially connected to the cam 5 .

[0054] As can be seen from the above description, the knob 7 plays a role in facilitating the driver's twisting. When the knob 7 is turned, the cam 5 is driven to rotate, thereby switching whether the cam 5 applies force to the directional block 3 and switching to the corresponding gear mode.

[0055] The basic principle of this invention is to apply opposing forces to the positioning block via the pressing member 2 and the elastic member 4, controlling the positioning slot on the positioning block to be retracted into or exposed from the surface of the through hole 12 of the faceplate, thereby enabling smooth switching between sequential and H gears. During operation, the driver rotates the knob 7, which in turn transmits the force to the positioning block via the cam 5, the push rod 6, and the pressing member 2, thereby controlling the positioning block's movement along the through hole 12.

[0056] Please refer to Figures 1 to 6 , Embodiment 1 of the present invention is: an H-speed sequential gear switching device, comprising a base 1, a pressing member 2, a directional block 3 and an elastic member 4;

[0057] The pressing member 2 is movably arranged on the base 1;

[0058] The base 1 is provided with an H-grade faceplate 11;

[0059] The H-gear faceplate 11 is provided with a through hole 12, and the orientation block 3 is movably embedded in the through hole 12. The orientation block 3 is provided with a sequence gear orientation slot 31;

[0060] The elastic member 4 is connected to the base 1 and the orientation block 3 respectively;

[0061] The pressing member 2 abuts against the orientation block 3 .

[0062] The directional block 3 is slidably disposed within the through hole 12 along an axis. A guide post 32 is provided on the directional block 3 in a direction parallel to the axis, and the base 1 is provided with a guide hole 13 that engages with the guide post 32. The guide post 32 is a bolt. The elastic member 4 is disposed in the guide hole 13 and is connected to the base 1 and the guide post 32, respectively. The elastic member 4 is a spring that abuts the tail end of the bolt. The directional block 3 is provided with a support post 33, and the pressing member 2 abuts the free end of the support post 33. There are two support posts 33, and there are two sets of pressing members 2. The free end of each support post 33 is provided with a supporting spherical surface that abuts the pressing member 2. The directional block 3 is provided with a limit plate 34 that is snap-fitted to the base 1. The middle portion of the pressing member 2 is rotatably connected to the base 1, and one end of the pressing member 2 abuts the directional block 3. It also includes a cam 5, which is rotatably mounted on the base 1 and abuts against the pressing member 2. The rotation axis of the cam 5 is perpendicular to the axis. It also includes a push rod 6. The pressing members 2 are provided in two groups, and the two ends of the push rod 6 are respectively connected to the two groups of pressing members 2. The middle portion of the push rod 6 abuts against the cam 5, and the push rod 6 is perpendicular to the rotation axis of the cam 5. The push rod 6 is perpendicular to the axis. It also includes a knob 7, which is rotatably mounted on the base 1 and coaxially connected to the cam 5.

[0063] In summary, the present invention provides an H-gear sequential gear switching device. On the basis of an H-gear faceplate provided on the base, a directional block that can be raised and lowered in the H-gear faceplate is designed. The directional block is provided with a sequential gear directional groove. The sequential gear directional groove limits the gear lever to move in one direction, which is equivalent to the gear position slot of the sequential gear. The raising and lowering of the positioning block in the H-gear faceplate is controlled by a pressing member and an elastic member. One situation is: when the pressing member does not apply force to the positioning block, the positioning block extends from the through hole of the H-gear faceplate under the elastic force of the elastic member, and the gear engagement mode is the sequential gear mode. When the pressing member applies force to the positioning block, the positioning block retracts into the through hole of the H-gear faceplate under the action of the pressing force, and the H-gear faceplate cooperates with the gear lever, and the gear engagement mode is the H-gear mode. Another situation is that when the pressing member does not apply force to the positioning block, the positioning block is hidden in the through hole of the H-gear disc under the elastic force of the elastic member. At this time, the gear mode is the H-gear mode. When the pressing member applies force to the positioning block, the positioning block extends from the through hole of the H-gear disc under the action of the pressing force. At this time, the sequential gear directional groove cooperates with the gear lever, and the gear mode is the sequential gear mode. The above two situations need to be flexibly selected according to the structural layout of the gear shifting device. The H-gear sequential gear switching device provided by the present invention changes the universal faceplate into a split faceplate, and selects and uses the corresponding gear shifting groove form in different gear shifting modes. Compared with the traditional method of using fasteners to limit the rotation of the gear shifting mechanism to achieve gear shifting mode switching, even if the gear shifter frequently switches modes or is used for a long time, it will not cause serious wear of the gear shifting structure and the faceplate structure, thereby ensuring the gear shifting accuracy, smoothness and operating feel, and saving the cost of repairing and replacing components.
