[0002] Fuel engines all have fuel supply control devices to change the fuel supply according to the engine's workload and engine speed, commonly known as manual throttles. However, existing manual throttles have the following defects: 1. They are prone to short circuits. The existing manual throttles have a circle of rotary dials and generally use potentiometers to read the gear position. Since the vehicle operating environment is relatively diverse and sometimes it is exposed to rain, the traditional manual throttle is prone to short circuits; 2. There is no intermediate limit. The existing manual throttle has the same feel within the effective operating range (between the highest gear and the lowest gear). If different feel is required within the effective operating range of the throttle gear to remind the driver whether the throttle is within a custom range, the traditional throttle cannot meet the requirements. Summary of the invention
[0003] In order to overcome the defects of the prior art, the present invention proposes a hand throttle with an intermediate limit.

DETAILED DESCRIPTION
[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.
[0017] like Figure 1-2As shown, in the embodiment, a hand throttle with an intermediate limit is provided, including a shell 1, a main shaft 2, a throttle lever 3, a MAX limit stop 4, a MIN limit stop 5, a limit stop damping adjustment member 6, a throttle damping adjustment member 7 and a throttle controller 8. The shell 1 is rotatably connected to the main shaft 2, and the throttle lever 3, the MAX limit stop 4 and the MIN limit stop 5 are sequentially arranged on the main shaft 2 along the axial direction, and the shell 1 is located between the MAX limit stop 4 and the MIN limit stop 5, and the limit stop damping adjustment member 6 is arranged on the side where the MAX limit stop 4 and the MIN limit stop 5 are away from each other. The limit stop damping adjustment member 6 includes a baffle 61, a fixing screw 62 and an auxiliary adjusting screw 63. The baffle 61 is sleeved on the main shaft 2, and the baffle 61 is connected to the shell 1 through the fixing screw 62 and the auxiliary adjusting screw 63. The throttle damping adjustment member 7 is connected to one end of the main shaft 2, and the throttle controller 8 is connected to the other end of the main shaft 2. In this embodiment, the main shaft 2 is arranged horizontally, and the throttle lever 3 is fixedly connected to the main shaft 2, which can drive the main shaft 2 to rotate synchronously. The MAX limit stop 4 and the MIN limit stop 5 are both rotationally connected to the main shaft 2, so that when the main shaft 2 rotates, the MAX limit stop 4 and the MIN limit stop 5 will not rotate. The limit stop damping adjustment member 6 is used to adjust the rotation damping of the MAX limit stop 4 and the MIN limit stop 5, wherein screw holes are provided at both ends of the baffle 61, and the fixing screw 62 and the auxiliary adjustment screw 63 are respectively located in one of the screw holes, and the fixing screw 62 is used to fix one end of the baffle 61 to the housing 1, and the auxiliary adjustment screw 63 can control the baffle 61 to squeeze the MAX limit stop 4 or the MIN limit stop 5 to form an operation damping, and by screwing the auxiliary adjustment screw 63, the damping size of the MAX limit stop 4 or the MIN limit stop 5 can be adjusted to change the operation feel. When in use, the user can move the MAX limit gear 4 and the MIN limit gear 5 to the required area. When the throttle lever 3 moves between the two limit gears, the damping is fixed. If the throttle gear is always raised, when it hits the MAX limit gear 4, the throttle lever 3 will drive the MAX limit gear 4 to move forward together. During operation, the user can clearly feel the feeling of damping superposition, that is, a clear sense of resistance. The effect of the throttle lever 3 hitting the MIN limit gear 5 when moving backward is the same. The throttle damping adjustment member 7 is set to adjust the rotational damping of the throttle lever 3, and the throttle damping adjustment member 7 and the limit gear damping adjustment member 6 cooperate with each other. When the throttle gear exceeds or is lower than the custom gear, a clear sense of resistance can be felt, thereby meeting different hand feel requirements. The throttle controller 8 is set to detect the rotation angle of the main shaft 2, and then control the acceleration or deceleration of the vehicle to realize the throttle control function.
[0018] Specifically, friction pads 9 are provided on both sides of the throttle lever 3, the MAX limit stop 4 and the MIN limit stop 5. In this embodiment, the friction pads 9 provided can protect the throttle lever 3, the MAX limit stop 4 and the MIN limit stop 5 from wear and tear, and are easy to replace when the friction pads 9 are damaged, thereby reducing maintenance costs. In addition, the friction pads 9 can also increase the friction force of the throttle lever 3, the MAX limit stop 4 and the MIN limit stop 5, thereby improving the damping effect.
[0019] Specifically, the throttle damping adjustment member 7 includes a main adjustment screw 71 and a wave washer 72. The main adjustment screw 71 is threadedly connected to the main shaft 2, and a wave washer 72 is arranged between the main adjustment screw 71 and the throttle stop lever 3. In this embodiment, the main adjustment screw 71 can control the squeezing of the wave washer 72, so that the throttle stop lever 3 and the stop plate 61 are pressed tightly to form operational damping, and by screwing the main adjustment screw 71, the damping size of the throttle stop lever 3 can be adjusted to change the operational feel. The wave washer 72 is an annular structure, and the wave washer 72 is sleeved on the main shaft 2. The wave washer 72 can prevent the main adjustment screw 71 from loosening under severe vibration conditions, resulting in a decrease in the operating force.
[0020] Specifically, the throttle controller 8 includes a permanent magnet 81 and a PCBA board 82, wherein the permanent magnet 81 is connected to the main shaft 2, and the PCBA board 82 is fixed on the housing 1. In the present embodiment, the permanent magnet 81 is embedded in the end of the main shaft 2 and can rotate synchronously with the main shaft 2. A Hall sensor is integrated on the PCBA board 82, which can accurately detect the rotation angle of the permanent magnet 81, and then obtain the rotation angle of the main shaft 2, so as to achieve precise control of the throttle. The PCBA board 82 is independent of other structures and is placed in an independent protective shell. Through the encapsulation manufacturing process, the main body of the PCBA board 82 is isolated from the outside world, thereby ensuring that the circuit board has no risk of short circuit due to contact with water, and the connector led out of the PCBA board 82 is also a waterproof connector to eliminate the risk of short circuit of the external wires of the circuit board.
[0021] Specifically, a bushing 10 is provided on the main shaft 2, and a retaining spring 11 is fixed on the main shaft 2 for locking the bushing 10. In this embodiment, the main shaft 2 is connected to the rotary hole on the housing 1 through the bushing 10. Retaining springs 11 are provided on both sides of the bushing 10 for limiting the axial freedom of the bushing 10 along the main shaft 2 and connecting the bushing 10 and the main shaft 2 as a whole.
