[0036] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0037] The present utility model provides an electric control handle base structure assembly, as Figures 1 to 14 shown.

[0038] An electric control handle base structure assembly includes a handle bracket 1, a handle pressing ring 2 with a Z-shaped groove, a handle connecting rod 3, an angle sensor 12, a connecting bracket 7, a torsion spring 8, and a microswitch assembly. The handle pressing ring 2 is installed on the upper end surface of the handle bracket 1, the angle sensor 12 is fixedly arranged on the connecting bracket 7, and a Z-shaped groove corresponding to the handle pressing ring 2 is opened on the upper end surface of the handle bracket 1.

[0039] The handle connecting rod 3 includes a joystick 31 and an inverted U-shaped connecting base 32 fixedly arranged at the bottom thereof, and a connecting hole is correspondingly opened on the U-shaped connecting base 32.

[0040] The connecting bracket 7 is set as an L-shaped plate. The L-shaped plate includes a main connecting plate 71 arranged vertically and a horizontal plate fixedly arranged at the bottom thereof for fixedly connecting with a circuit board 10, and extension arms 72 for connecting with the inverted U-shaped connecting base 32 are also arranged on both sides of the main connecting plate 71.

[0041] During installation, the torsion spring 8 is sleeved on the joystick 31, and the handle connecting rod 3 and the connecting bracket 7 are assembled by sequentially passing a pin shaft through the extension arm 72 of the connecting bracket 7, the connecting hole of the inverted U-shaped connecting base 32, and the torsion spring 8.

[0042] A disc spring 5, a limit plate 6, and a nylon sleeve 4 are also assembled between the handle bracket 1 and the connecting bracket 7. The nylon sleeve 4 is arranged on both sides of the main connecting plate 71 and sleeved on the angle sensor 12 respectively. The limit plate 6 is in contact with and fixedly sleeved on the angle sensor 12 above the microswitch assembly to rotate synchronously with it. One side of the disc spring 5 is attached to the vertical plate of the handle bracket 1, and the other side is in contact with the limit plate 6. The limit plate 6 needs to be a metal limit plate.

[0043] In this embodiment, the nylon sleeve close to the handle connecting rod 3 is denoted as the first nylon sleeve, and a limit retaining ring 13 is also arranged on the outer side thereof. The limit retaining ring 13 is also a metal retaining ring. Both the first nylon sleeve and the limit retaining ring 13 are sleeved on the large diameter section of the angle sensor 12. The nylon sleeve close to the disc spring 5 is denoted as the second nylon sleeve. The disc spring 5, the limit plate 6, the second nylon sleeve, and the connecting bracket 7 are sequentially coaxially sleeved on the small diameter section of the angle sensor 12 and fixed axially by corresponding long bolts.

[0044] For convenient installation and cooperation, the limit plate 6 is set as a disc-shaped structure, and a fan-shaped area is opened on the outer edge thereof.

[0045] During operation, the handle connecting rod 3 moves back and forth, driving the connecting bracket 7, which in turn drives the angle sensor 12 fixed on the connecting bracket 7 to rotate. The angle sensor 12 drives the limit plate 6 sleeved on the angle sensor 12 to rotate, and the rotation of the limit plate 6 presses the microswitch 11; when a part outside the fan-shaped area of the limit plate contacts the microswitch, the microswitch is pressed to close, and within the fan-shaped area, the microswitch is in an open state; the sensor can collect signals and output corresponding electronic control signals according to the sensor characteristics, thereby controlling the traveling speed of the vehicle; and the connecting bracket adjusts the resistance of the handle connecting rod back and forth through the locking of the disc spring and the damping sleeve to meet the requirements of different operators for the operating force. At the same time, the torsion spring applies torque to the handle connecting rod in the middle position to reset the switch.

[0046] More specifically, the handle pressing ring 2 is fixedly connected to the handle bracket 1 by four countersunk head screws; the microswitch 11 is welded to the circuit board 10 to form a microswitch assembly. The angle sensor 12 is fixedly connected to the connecting bracket 7 by screws; secondly, the assembled microswitch assembly is fixedly connected to the connecting bracket 7 on which the angle sensor has been installed by screws, and then the nylon sleeve 4 and the metal limit retaining ring 13 are sleeved on the large-diameter end of the angle sensor 12 in sequence. The small-diameter end of the angle sensor 12 is also sleeved with the metal limit plate 6, the nylon sleeve 4, the disc spring 5 and the handle bracket 1 with the handle pressing ring 2 installed in sequence. Except for the corresponding center holes, the positioning small holes on both sides of the center holes also need to correspond one by one, and are fixedly connected at one time through the provided long bolts, thereby forming a semi-finished handle bracket.

[0047] Subsequently, the torsion spring 8, the handle connecting rod 3 and the semi-finished handle bracket that has been assembled are fixedly connected by the pin shaft 9. During the fixing process, it is necessary to make the central axis of the handle connecting rod 3 parallel to the main connecting plate 71 of the connecting bracket 7 by compressing the torsion spring 8. At this time, the handle connecting rod 3 is just in the center hole of the stroke of the handle bracket 1, and the pin shaft is tightened to complete the overall assembly.

[0048] Among them, a Z-shaped groove structure is made on the handle bracket 1, and the handle connecting rod 3 can move in the Z-shaped groove. While realizing the forward and backward rotation of the handle connecting rod, the left and right rotation of the handle connecting rod 3 is also realized. A disc spring 5 and a nylon sleeve 4 are installed between the handle bracket 1 and the connecting bracket 7. The friction force of the damping sleeve 4 is adjusted through the elasticity of the disc spring 5, so that the handle connecting rod 3 has a forward and backward degree of freedom to realize the damping function and meet the requirements of different vehicle models.

[0049] When the handle connecting rod 3 moves back and forth, it drives the connecting bracket 7, which in turn drives the angle sensor 12 fixed on the connecting bracket 7 to rotate. This further drives the limit plate 6 sleeved on the angle sensor 12 to rotate. The rotation of the limit plate 6 squeezes the microswitch 11 to close (the microswitch can be squeezed to close only when the part outside the fan-shaped area of the limit plate contacts the microswitch. Within the fan-shaped area, the microswitch is in an open state). The sensor can collect signals and output corresponding electronic control signals according to the sensor characteristics, thereby controlling the traveling speed of the vehicle.

[0050] In addition, the connecting bracket realizes the resistance adjustment of the handle connecting rod back and forth through the locking of the disc spring and the damping sleeve, adapting to the requirements of different operators for the use force. The torsion spring gives the handle rod in the middle position a torsion force to reset the switch.

[0051] For the overall structure of the electronic control handle base, the operating rod and the inverted U-shaped connecting base are integrally formed into the handle connecting rod 3, and are connected to the connecting bracket 7 through a pin shaft. The disc spring, the limit plate, the second nylon sleeve and the connecting bracket are coaxially sleeved on the small diameter section of the angle sensor in sequence, and are axially fixed by the corresponding long bolts, making the installation and disassembly more convenient. At the same time, the adoption of the nylon sleeve washer ensures a certain wear resistance.
