Description

Technical Field

[0001] This application relates to the field of agricultural implement design and manufacturing technology, specifically to a goji berry cart throttle control handle. Background Technology

[0002] Traditional handles use a two-axis cross design, which cannot achieve master-slave control when shifting between forward / backward and left / right gears. That is, while controlling the vehicle's forward or backward movement, it cannot control the vehicle's left and right rotation. In the application scenario of goji berry picking vehicles, this cannot meet the complex work requirements and also has some limitations in terms of flexibility and multi-functionality.

[0003] Traditional handles perform poorly when handling fine adjustments (such as small angle adjustments), which can affect the precise control of vehicle speed and working components, especially in agricultural machinery applications that require high-precision operation.

[0004] Traditional levers lack an effective locking mechanism, which may lead to accidental switching from forward to reverse gear during actual operation, increasing operational risks and safety hazards. Utility Model Content

[0005] In view of this, the main purpose of this application is to provide a throttle control handle for a goji berry vehicle, which helps to solve the problems of existing handles being unable to achieve master-slave control, having poor accuracy in small-angle adjustment, and lacking an effective locking mechanism, resulting in inconvenience in operation and safety hazards.

[0006] This application provides a goji berry-flame accelerator control handle, which includes:

[0007] The guide base is equipped with a first Hall sensor, a thin-walled bearing and a first rotation damper. A guide groove is provided at the upper end of the guide base. Locking structures are provided on both sides of the guide groove along its arc. Two throttle brackets are provided on the outer wall of the guide base. The two throttle brackets are located outside the guide groove.

[0008] The throttle linkage includes an upper connecting part located at its upper end, a transmission part located in the middle, and a lower connecting part located at its lower end. The lower connecting part is assembled inside the guide base and is connected to a first Hall sensor, a thin-walled bearing, and a first rotation damper, respectively. The transmission part extends out of the guide groove and is provided with a wire groove. The wire groove is equipped with a wire groove cover plate.

[0009] The reverse gear locking lever is sleeved on the transmission part. The upper end of the reverse gear locking lever is provided with a protrusion, and a spring is installed inside the protrusion. The spring abuts against the transmission part. The lower end of the reverse gear locking lever is provided with a locking block. When the throttle linkage slides along the guide groove to the top of the guide base, the locking block is locked in the locking structure under the action of the spring.

[0010] The handle body includes a self-locking button, a button front cover, a handle knob, and a handle crossbar. The self-locking button is mounted at the center of the button front cover. One side of the handle knob is fitted onto the button front cover, and the other side of the handle knob is fitted onto the handle crossbar. The handle crossbar is equipped with a second Hall sensor, a button bracket disc, an upper connecting part, and a second rotation damper. The button support is sequentially mounted on the mounting ring plate, button bracket disc, upper connecting part, handle knob, and button front cover inside the handle crossbar.

[0011] As described above, by employing a first Hall sensor and a second Hall sensor to achieve non-contact angle detection, more accurate position feedback can be provided. The first Hall sensor detects the rotation angle of the throttle linkage, while the second Hall sensor detects the rotation angle of the handle knob, providing precise angular position feedback for the vehicle's forward, reverse, and left / right rotation, thereby improving operational accuracy and the precision of small-angle adjustments. The handle knob is assembled with the handle crossbar, allowing the operator to rotate the handle knob with their thumb and forefinger while simultaneously controlling forward and reverse movement, thus controlling the vehicle's left and right yaw. This enables the throttle control handle of the vehicle to be used for master-slave control. Furthermore, a self-locking button is provided for the handle knob; when the self-locking button is pressed, the handle knob... The angle of rotation is required for it to function, providing double insurance and improving safety. The cable groove on the throttle linkage guides the cable of the second Hall sensor and the cable of the self-locking button to the lower end, where they converge and connect to the vehicle's control terminal. The cooperation between the reverse gear locking lever and the locking structure effectively prevents the operator from accidentally sliding from forward gear into reverse gear. The spring in the protrusion allows the locking block to automatically lock in the position of the locking structure, preventing safety hazards caused by misoperation. The first and second rotation dampers achieve mechanical damping positioning for the throttle linkage and the handle knob, respectively, allowing the throttle linkage and the handle knob to be locked to their respective positions, facilitating analog quantity control of vehicle movement and harvesting operations.

[0012] Optionally, the guide base includes: a base with a first notch in a 180° fan-shaped structure on one side of its opening, and a sliding groove in a 90° fan-shaped structure on the first notch; a base side cover with a locking groove at its top. After the base and the base side cover are fixedly connected from left to right, the first notch forms a guide groove for the guide base, and the sliding groove and the locking groove form a locking structure.

[0013] As shown above, the guide groove formed by the first notch provides a clear guide path for the movement of the throttle linkage. The locking structure formed by the sliding groove and the locking groove enables the throttle linkage to be mechanically locked at a specific position (such as the middle position between forward and reverse gears), preventing misoperation and improving the safety of operation.

[0014] Optionally, the lower connecting part is connected to the first Hall sensor, the thin-walled bearing, and the first rotation damper, and further includes: a first annular structure provided on one side of the lower connecting part is sleeved on the central axis of the first Hall sensor; the outer wall of the second annular structure provided on the other side of the lower connecting part is sleeved on the inner ring of the thin-walled bearing, and the first rotation damper is assembled in the inner wall groove of the second annular structure.

[0015] As described above, the first annular structure is fitted onto the central axis of the first Hall sensor, ensuring that the throttle linkage can directly and accurately transmit rotational position information to the first Hall sensor to provide precise angular position feedback; the use of a thin-walled shaft provides smoother operation for the throttle linkage, enabling it to rotate smoothly and stably; the first rotation damper ensures that the handle bar and throttle linkage can obtain appropriate resistance at different angles during the pushing process, which not only improves the operator's feel but also helps the operator to make better fine adjustments.

[0016] Optionally, the outer ring of the thin-walled bearing is fixed to the inner wall of the base.

[0017] As shown above, the thin-walled bearing is fixed on the inner wall of the base to ensure smooth sliding of the throttle linkage.

[0018] Optionally, an annular mounting plate is provided at the center of the inner groove of the base, and the first disk of the first rotation damper is fixedly mounted on the annular mounting plate, while the second disk of the first rotation damper is fixed in the inner wall groove of the second annular structure.

[0019] As shown above, the two discs of the first rotary damper are fixed to the base (stationary part) and the lower connecting part (moving part) respectively. When the handle body is operated to drive the throttle linkage to rotate, the two discs rotate relative to each other, thereby exerting a damping effect and giving the handle body a good feel during operation.

[0020] Optionally, the handle crossbar is equipped with a second Hall sensor, a button bracket disc, an upper connecting part, and a second rotation damper. It also includes: one side of the second Hall sensor is fixed to a mounting ring plate inside the handle crossbar, and the button bracket disc, the upper connecting part, and the second rotation damper are sequentially sleeved on the central axis of the other side of the second Hall sensor; the third disc of the second rotation damper is fixed to one side of the upper connecting part, and the fourth disc of the second rotation damper is fixed inside the handle knob.

[0021] As described above, the second Hall sensor can accurately sense the rotation angle of the handle knob, thereby enabling precise control of the vehicle; the second slewing damper provides appropriate resistance to help prevent the handle knob from changing position due to accidental collisions, increasing operational safety.

[0022] Optionally, the lower end of the reverse gear locking lever is hollow and sleeved on both sides of the lower end of the transmission part; a locking block is provided on the front side of the lower end of the reverse gear locking lever, the locking block includes a first locking block and a second locking block, the first locking block cooperates with the locking groove, the second locking block cooperates with the sliding groove, and the length of the second locking block is greater than the length of the first locking block; the mounting through holes provided on the front side of the lower end of the reverse gear locking lever are rotatably connected to the corresponding positions at the lower end of the transmission part through a movable shaft.

[0023] As shown above, the length of the second locking block is greater than that of the first locking block, so that when the throttle linkage is pushed forward, the second locking block can slide inside the slide groove, and the first locking block can slide along the outer wall of the base side cover; according to the limitation of the movable shaft set at the corresponding position of the transmission part, the reverse gear locking lever can rotate up and down around the transmission part with the movable shaft as the center.

[0024] Optionally, an annular groove is provided on the front cover of the button, and a damping O-ring is fitted inside the annular groove.

[0025] As mentioned above, the damping O-ring can enhance the seal between the button front cover and the handle knob.

[0026] Optionally, a fixing plate is provided inside the handle crossbar, and the second Hall sensor is mounted on the fixing plate.

[0027] Therefore, the second Hall sensor is installed on the fixed plate inside the handle crossbar to ensure that the position of the second Hall sensor remains fixed and will not shift due to vibration or rotation during operation.

[0028] Optionally, the first Hall sensor is mounted on a side cover mounting plate inside the base side cover via a sensor mounting plate.

[0029] As described above, by fixing the sensor to the side cover mounting plate inside the base side cover through the sensor mounting plate, it can be ensured that the first Hall sensor can remain fixed during use, and the position of the first Hall sensor will not be shifted due to operational vibration or mechanical movement.

[0030] In summary, the throttle control lever for the wolfberry vehicle provided in this application has a 180° fan-shaped guide groove on the guide base, which provides a clear guide path for switching between forward and reverse gears on the throttle linkage. At the midpoint between forward and reverse gears, i.e., at the top of the guide base, a slot is provided on one side of the top of the guide base, and a 90° fan-shaped sliding groove is provided on the other side. The slot and the sliding groove constitute the locking structure of the guide base. The slot corresponds to the first locking block at the lower end of the reverse gear locking lever, and the sliding groove corresponds to the second locking block at the lower end of the reverse gear locking lever. When the first and second locking blocks slide to the top position of the guide base, they cooperate with the locking structure under the action of the spring in the upper protrusion of the reverse gear locking lever, preventing the throttle lever from accidentally sliding from forward to reverse gear. Furthermore, the second locking block remains within the sliding groove. This design provides dual protection for the locking mechanism to ensure the connecting block can smoothly fall into the locking structure. The first Hall sensor and the second Hall sensor detect the rotation angle of the throttle linkage and the handle knob, respectively, providing precise angular position feedback for the vehicle's forward, backward, and left / right rotation, thereby improving the accuracy of operation and the precision of small-angle adjustments. When the operator holds the handle bar, the handle knob is located on the thumb side, and the self-locking button is located on the side of the handle knob. When the operator holds the handle bar and pushes the throttle linkage forward or backward, the thumb and forefinger can simultaneously rotate the handle knob, and after rotating a certain angle, the thumb presses the self-locking button to complete the precise small-angle adjustment. The rotation damper provides mechanical damping positioning for the rotation of the throttle linkage and the handle knob, enabling the throttle linkage and the handle knob to be locked to their respective positions.

[0056] Figure 1-2 This application provides an overall structural and internal structural view of a goji berry-flavored vehicle throttle control handle; the application provides a goji berry-flavored vehicle throttle control handle, which includes:

[0057] The guide base 1 is equipped with a first Hall sensor 13, a thin-walled bearing 14 and a first rotation damper 15. The upper end of the guide base 1 is provided with a guide groove 1101. Locking structures are provided on both sides of the guide groove 1101 along its arc. Two throttle brackets 16 are provided on the outer wall of the guide base 1. The two throttle brackets 16 are located outside the guide groove 1101.

[0058] The throttle linkage 2 includes an upper connecting part 21 located at its upper end, a transmission part 22 located in the middle, and a lower connecting part 23 located at its lower end. The lower connecting part 23 is assembled inside the guide base 1 and is connected to the first Hall sensor 13, the thin-walled bearing 14, and the first rotation damper 15 respectively. The transmission part 22 extends out of the guide groove 1101 and is provided with a wire groove 2201. The wire groove 2201 is equipped with a wire groove 2201 cover plate.

[0059] The reverse gear locking lever 3 is sleeved on the transmission part 22. The upper end of the reverse gear locking lever 3 is provided with a protrusion 31, and a spring is installed inside the protrusion 31. The spring abuts against the transmission part 22. The lower end of the reverse gear locking lever 3 is provided with a locking block. When the throttle linkage 2 slides along the guide groove 1101 to the top of the guide base 1, the locking block is locked in the locking structure under the action of the spring.

[0060] The handle body 4 includes a self-locking button 41, a button front cover 42, a handle knob 43, and a handle crossbar 44. The self-locking button 41 is mounted at the center of the button front cover 42. One side of the handle knob 43 is fitted onto the button front cover 42, and the other side of the handle knob 43 is fitted onto the handle crossbar 44. The handle crossbar 44 is equipped with a second Hall sensor 45, a button bracket disc 47, an upper connecting part 21, and a second rotation damper 46. The button support rod 48 is sequentially mounted on the mounting ring plate 4401, the button bracket disc 47, the upper connecting part 21, the handle knob 43, and the button front cover 42 inside the handle crossbar 44.

[0061] Specifically, by employing a first Hall sensor 13 and a second Hall sensor 45 to achieve non-contact angle detection, more accurate position feedback can be provided. The first Hall sensor 13 detects the rotation angle of the throttle linkage 2, and the second Hall sensor 45 detects the rotation angle of the handle knob 43, providing precise angular position feedback for the vehicle's forward, reverse, and left / right rotation, thereby improving operational accuracy and the precision of small-angle adjustments. The handle knob 43 is assembled with the handle crossbar 44, allowing the operator to rotate the handle knob 43 with their thumb and forefinger while simultaneously manipulating forward and reverse movement, thus controlling the vehicle's left and right yaw. This enables the throttle control handle of the vehicle to be used for master-slave control. Furthermore, a self-locking button is provided for the handle knob 43; when the self-locking button 41 is pressed, the handle knob 43... The angle of rotation is required for it to function, providing double insurance and improving safety. The wire groove 2201 on the throttle linkage 2 guides the cable of the second Hall sensor 45 and the cable of the self-locking button 41 to the lower end, where they converge with the cable of the second Hall sensor 45 and connect to the vehicle's control terminal. The cooperation between the reverse gear locking lever 3 and the locking structure can effectively prevent the operator from accidentally sliding from forward gear to reverse gear. The spring in the protrusion 31 allows the block to automatically lock in the position of the locking structure, preventing safety hazards caused by misoperation. The first rotation damper 15 and the second rotation damper 46 respectively achieve mechanical damping positioning of the throttle linkage 2 and the handle knob 43, which can lock the throttle linkage 2 and the handle knob 43 to their respective positions, facilitating analog quantity control of vehicle movement and harvesting operations.

[0062] Optionally, the guide base 1 includes: a base 11, on one side of which is provided a first notch with a 180° fan-shaped structure, and a sliding groove 1102 with a 90° fan-shaped structure is provided on the first notch; a base side cover 12, on the top of which is provided a locking groove 1201. After the base 11 and the base side cover 12 are fixedly connected from left to right, the first notch forms the guide groove 1101 of the guide base 1, and the sliding groove 1102 and the locking groove 1201 form a locking structure.

[0063] Specifically, the guide groove 1101 formed by the first notch provides a clear guide path for the movement of the throttle linkage 2. The locking structure formed by the slide groove 1102 and the locking groove 1201 enables the throttle linkage 2 to be mechanically locked at a specific position (such as the middle position between forward and reverse gears), preventing misoperation and improving the safety of operation.

[0064] Optionally, the first Hall sensor 13 is mounted on the side cover mounting plate 1202 inside the base side cover 12 via the sensor mounting plate 1301.

[0065] Specifically, by fixing the sensor 13 to the side cover mounting plate 1202 inside the base side cover 12 using the sensor mounting plate 1301, it can be ensured that the first Hall sensor 13 can remain fixed during use, and the position of the first Hall sensor 13 will not shift due to operational vibration or mechanical movement.

[0066] Optionally, the lower connecting part 23 is connected to the first Hall sensor 13, the thin-walled bearing 14 and the first rotation damper 15 respectively, and further includes: a first annular structure 2301 provided on one side of the lower connecting part 23 is sleeved on the central axis of the first Hall sensor 13; the outer wall of the second annular structure 2302 provided on the other side of the lower connecting part 23 is sleeved on the inner ring of the thin-walled bearing 14, and the first rotation damper 15 is assembled in the inner wall groove of the second annular structure 2302.

[0067] Specifically, the first annular structure 2301 is sleeved on the central axis of the first Hall sensor 13, ensuring that the throttle linkage 2 can directly and accurately transmit the rotational position information to the first Hall sensor 13 to provide precise angular position feedback; the use of a thin-walled shaft provides a smoother operation for the throttle linkage 2, enabling the throttle linkage 2 to rotate smoothly and stably; the first rotation damper 15 ensures that the handle bar 44 and the throttle linkage 2 can obtain appropriate resistance at different angle positions during the pushing process, which not only improves the operator's operating feel, but also helps the operator to make better fine adjustments.

[0068] Optionally, the outer ring of the thin-walled bearing 14 is fixed to the inner wall of the base 11.

[0069] Specifically, the thin-walled bearing 14 is fixed on the inner wall of the base 11 to ensure smooth sliding of the throttle linkage 2.

[0070] Optionally, an annular mounting plate 1103 is provided at the center of the inner circular groove of the base 11. The first disk 1501 of the first rotation damper 15 is fixedly mounted on the annular mounting plate 1103, and the second disk 1502 of the first rotation damper 15 is fixedly mounted in the inner wall circular groove of the second annular structure 2302.

[0071] Specifically, the two discs of the first rotation damper 15 are fixed to the base 11 (stationary part) and the lower connecting part 23 (moving part) respectively. When the handle body 4 operates and drives the throttle linkage 2 to rotate, the two discs rotate relative to each other, thereby playing a damping role and giving the handle body 4 a good feel during operation.

[0072] [Specific Embodiment of Guide Base 1]

[0073] The guide base 1 is generally in the shape of a horizontally arranged cylinder, and the guide base 1 includes a base 11 (such as...). Figures 3a-3b The base structure shown) and the base side cover 12 (as shown) Figures 4a-4b The base 11 is cylindrical, with a semi-circular first notch on one side of the opening. A 90° fan-shaped sliding groove 1102 is provided on the first notch. A slot 1201 is provided at the top of the base side cover 12. The base 11 and the base side cover 12 are placed side to side and spliced ​​to form a 180° fan-shaped guide groove 1101. The slot 1201 and the sliding groove 1102 respectively receive the first locking block 32 and the second locking block 33 on both sides of the lower end of the reverse gear locking lever 3. When the throttle linkage 2 slides along the guide groove 1101 to its top, the second locking block 33 is blocked when it slides along the sliding groove 1102 to its top. The first locking block 32 is locked in the slot 1201 under the downward pressure of the spring. When reverse gear is needed, the operator lifts the protrusion 31 with his finger, and the two locking blocks also lift upward, thereby disengaging from the sliding groove 1102 and the slot 1201. Then the operator can hold the handle body 4 to reverse gear.

[0074] The outer ring of the thin-walled bearing 14 is secured to the inner circular wall of the base 11; screw holes are provided on the side below the first notch of the base 11, and corresponding through holes are also provided on the side below the base side cover 12. When the base 11 and the base side cover 12 are placed side to side, they can be fixed together by screws; large through holes are symmetrically provided on the lower outer wall of the base 11, and large through holes are also symmetrically provided on the lower outer wall of the base side cover 12. After the two are fixed together, the large through holes can be used to install two throttle brackets 16 (see...). Figure 5 ).

[0075] The first Hall sensor 13 measures the angular position of the throttle linkage 2. The first Hall sensor 13 is fixed to the side cover mounting plate 1202 of the base side cover 12 by the sensor mounting plate 1301. The sensor mounting plate 1301 can be fixed by bolts or screws. The first Hall sensor 13 is set through the base side cover 12. The central axis of one side of the first Hall sensor 13 is inserted into the central hole of the first annular structure 2301 of the lower connecting part 23 of the throttle linkage 2.

[0076] When the operator pushes or pulls the throttle linkage 2, the first Hall sensor 13 senses the change in the position of the throttle linkage 2 and outputs a corresponding voltage signal based on the change in the position of the throttle linkage 2. This voltage signal is proportional to the displacement of the throttle linkage 2. The electrical signal emitted by the first Hall sensor 13 is sent to the vehicle's control system and performs precise position feedback according to the PID algorithm, so that the operator can operate the throttle control lever well.

[0077] [Specific Implementation of Throttle Link 2]

[0078] like Figures 6a-6b As shown, the throttle linkage 2 includes an upper connecting part 21, a transmission part 22 located in the middle, and a lower connecting part 23. The upper connecting part 21 and the lower connecting part 23 are generally circular. The top of the upper connecting part 21 is provided with a through hole for wiring. The transmission part 22 has a long strip-shaped wire groove 2201 cut from top to bottom. The length of the wire groove 2201 is on the same straight line as the center of the upper connecting part 21 and the lower connecting part 23. The upper and lower sides of the wire groove 2201 are provided with through holes for wiring, namely signal wires and power wires. The wire groove 22 is mounted on the wire groove 2201. 01. The cover plate and the wire groove 2201 are provided with corresponding mounting holes on the same side to fix them. A first annular structure 2301 is provided on one side of the lower connecting part 23, and the central shaft of the first Hall sensor 13 is inserted into the first annular structure 2301. A second annular structure 2302 is provided on the other side of the lower connecting part 23. The second annular structure 2302 is sleeved on the inner ring of the thin-walled bearing 14. The inner wall groove of the second annular structure 2302 in the lower connecting part 23 is provided with stepped holes to support the first rotation damper 15.

The lower front of the reverse gear locking rod 3 is provided with a first locking block 32 and a second locking block 33. The first locking block 32 cooperates with the slot 1201 at the top of the base side cover 12, and the second locking block 33 cooperates with the slide groove 1102 on the base 11. The length of the second locking block 33 is greater than the length of the first locking block 32, so that when the throttle linkage 2 is pushed forward, the second locking block 33 can slide inside the slide groove 1102, and the first locking block 32 can slide along the outer wall of the base side cover 12.

[0084] Optionally, the handle crossbar 44 is internally equipped with a second Hall sensor 45, a button bracket disc 47, an upper connecting part 21, and a second rotation damper 46. It also includes: one side of the second Hall sensor 45 is fixed on a mounting ring plate 4401 provided inside the handle crossbar 44, and the button bracket disc 47, the upper connecting part 21, and the second rotation damper 46 are sequentially sleeved on the central axis of the other side of the second Hall sensor 45; the third disc 4601 of the second rotation damper 46 is fixed on one side of the upper connecting part 21, and the fourth disc 4602 of the second rotation damper 46 is fixed inside the handle knob 43.

[0085] Specifically, the second Hall sensor 45 can accurately sense the rotation angle of the handle knob 43, thereby enabling precise control of the vehicle; the second slewing damper 46 provides appropriate resistance to help prevent the position of the handle knob 43 from changing due to accidental collisions, thus increasing operational safety.

[0086] Optionally, a fixing plate is provided inside the handle crossbar 44, and the second Hall sensor 45 is mounted on the fixing plate.

[0087] Specifically, the second Hall sensor 45 is installed on a fixed plate inside the handle crossbar 44 to ensure that the position of the second Hall sensor 45 remains fixed and that the position of the second Hall sensor 45 will not shift due to vibration or rotation during operation.

[0088] Optionally, an annular groove 4201 is provided on the button front cover 42, and a damping O-ring 49 is fitted inside the annular groove 4201.

[0089] Specifically, the damping O-ring 49 enhances the seal between the button front cover 42 and the handle knob 43.

[0090] [Specific Implementation of Handle Body 4]

[0091] The handle body 4 includes a self-locking button 41, a button front cover 42, a handle knob 43, and a handle crossbar 44.

[0092] The self-locking button 41 is fixedly mounted at the center of the button front cover 42. Symmetrical through holes are provided at both ends of the central through hole in the button front cover 42. An annular groove 4201 is provided on the button front cover 42, and a damping O-ring 49 is fitted inside the annular groove 4201. One side of the handle knob 43 is fitted onto the button front cover 42 where the damping O-ring 49 is located. The damping O-ring 49 enhances the sealing between the handle knob 43 and the button front cover 42. The other side of the handle knob 43 is fitted onto the handle crossbar 44, and the handle knob 43 is positioned such that when the operator grips the handle crossbar 44, it... The operation position should be between the thumb and forefinger, and the rotation action is achieved by the thumb and forefinger working together. The position of the self-locking button 41 corresponds to the thumb side. When the thumb and forefinger rotate the handle knob 43 to a certain angle, the thumb presses the self-locking button 41, the electrical signal is triggered and transmitted to the control system of the goji berry picking vehicle. The PID algorithm controls the rotation angle of the handle knob 43 after the self-locking button 41 is pressed, so that the front wheel of the vehicle can turn left and right. A scale can also be set around the front cover 42 of the button for reference angle when the handle knob 43 is rotated.

[0093] like Figure 8As shown, the handle crossbar 44 is a hollow cylinder. On the handle crossbar 44, near the handle knob 43, there is a notch to allow the transmission part 22 of the throttle linkage 2 to extend into the handle crossbar 44. A mounting ring plate 4401 is provided inside the handle crossbar 44 near the notch. The mounting ring plate 4401 has symmetrical through holes around its periphery to connect the button bracket disc 47 and the upper connecting part 21 of the throttle linkage 2. The through holes on the mounting ring plate 4401 correspond to the through holes of the button bracket disc 47 and the upper connecting part 21 of the throttle linkage 2. The second Hall sensor 45 passes through the center hole of the mounting ring plate 4401, the center hole of the button bracket disc 47, and the center hole of the upper connecting part 21 of the throttle linkage 2 in sequence, and the second Hall sensor 45 is fixedly installed on the mounting ring plate 4401 inside the handle crossbar 44.

[0094] The handle crossbar 44 is equipped with a second Hall sensor 45, a button bracket disc 47, a button support rod 48, an upper connecting part 21 of the throttle linkage 2, and a second rotation damper 46; the second Hall sensor 45 measures the angular position of the handle knob 43.

[0095] like Figure 12 As shown, one end of the second Hall sensor 45 is provided with a stepped shaft with concentric circles. The upper connecting part 21 of the throttle linkage 2 and the second rotation damper 46 are sequentially mounted on the two stepped shafts. The diameter of the stepped shaft with the upper connecting part 21 is larger than the diameter of the stepped shaft with the second rotation damper 46. The upper connecting part 21 of the throttle linkage 2 is provided with a plurality of symmetrically distributed through holes. The through holes of the upper connecting part 21 correspond to the through holes on the button bracket disc 47. Two symmetrically distributed through holes are used for the two button support rods 48 to pass through, and the other through holes are used to fix the button bracket disc 47 and the upper connecting part 21 together. The mounting ring plate 4401 inside the handle crossbar 44 is also provided with through holes corresponding to the upper connecting part 21 and the button bracket disc 47, and two symmetrically distributed through holes are used for the two button support rods 48 to pass through, as can be seen from... Figure 2 and Figure 11 The structure shown includes other through holes for fixing the mounting ring plate 4401, the button bracket disc 47, and the upper connecting part 21 together; one end of the button support rod 48 passes through the corresponding through holes in the mounting ring plate 4401, the button bracket disc 47, and the upper connecting part 21, and the other end of the button support rod 48 is inserted into the side through hole of the button front cover 42, and the button support rod 48 holds the button front cover 42 and the handle crossbar 44 together; one of the two button support rods 48 has an upward through hole at the position near the self-locking button 41, for transmitting the signal line, power line, and other cables of the self-locking button 41 through the button support rod 48 to one end of the second Hall sensor 45, and transmitting them together with the signal line and power line of the second Hall sensor 45 to the lower guide base 1.

[0096] like Figure 13 As shown, the third disc 4601 on one side of the second rotation damper 46 is fixed to the upper connecting part 21 by screws, and the fourth disc 4602 on the other side of the second rotation damper 46 is fixedly connected to the hollow disc on one side inside the handle knob 43 (see...). Figure 9 The second rotation damper 46 provides mechanical damping positioning for the rotation of the handle knob 43, and can lock the handle knob 43 to any position.

[0097] In summary, the throttle control handle for the wolfberry vehicle provided in this application has a 180° fan-shaped guide groove 1101 on the guide base 1, which provides a clear guide path for switching between forward and reverse gears on the throttle linkage 2. At the midpoint between forward and reverse gears, i.e., at the top of the guide base 1, a slot 1201 is provided on one side of the top of the guide base 1, and a 90° fan-shaped sliding groove 1102 is provided on the other side of the top of the guide base 1. The slot 1201 and the sliding groove 1102 constitute the locking structure of the guide base 1. The slot 1201 corresponds to the first locking block 32 at the lower end of the reverse gear locking lever 3, and the sliding groove 1102 corresponds to the second locking block 33 at the lower end of the reverse gear locking lever 3. When the first locking block 32 and the second locking block 33 slide to the top position of the guide base 1, they cooperate with the locking structure under the action of the spring in the upper protrusion 31 of the reverse gear locking lever 3, preventing the throttle handle from accidentally sliding from forward gear into reverse gear. The lever 1102 slides continuously within the groove, providing double protection for the locking block to fall smoothly into the locking structure. The first Hall sensor 13 and the second Hall sensor 45 detect the rotation angle of the throttle linkage 2 and the handle knob 43 respectively, providing precise angular position feedback for the vehicle's forward, backward, and left / right rotation, thereby improving the accuracy of operation and the precision of small angle adjustments. When the operator holds the handle bar 44, the handle knob 43 is located on the thumb side, and the self-locking button 41 is located on the side of the handle knob 43. When the operator holds the handle bar 44 and pushes the throttle linkage 2 forward or backward, the thumb and forefinger can simultaneously rotate the handle knob 43, and after rotating a certain angle, the thumb presses the self-locking button 41 to complete the precise small angle adjustment. The rotation damper provides mechanical damping positioning for the rotation of the throttle linkage 2 and the handle knob 43, which can lock the throttle linkage 2 and the handle knob 43 to their respective positions.
