[0028] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the following embodiments will specifically describe the present invention in conjunction with the accompanying drawings. And it is defined that Figure 4 the direction from top to bottom shown in the paper surface is the direction from back to front in this embodiment.

[0029] Embodiment 1,

[0030] Referring to Figure 1 and Figure 2 shown in, the joystick with control functions provided in this embodiment is applied to a riding mower. The riding mower has a mowing disc 7, traveling wheels 6, and a drive assembly for controlling the traveling speed and traveling direction of the traveling wheels 6. The joystick includes:

[0031] A tubular rod body 1, the first end of which is used to be assembled into the riding lawn mower and is connected to the driving assembly, and the second end is cut into an annular installation section 11, and the tubular rod body 1 has a channel 13 for routing and passing through both ends, and the outer diameter of the annular installation section 11 is smaller than the outer diameter of the main part of the tubular rod body 1;

[0032] The knob control module 2 is sleeved on the outer circumference of the annular mounting section 11, and the signal transmission line of the knob control module 2 extends into the channel 13;

[0033] The button control module 3 has its electrical connection end inserted into the channel 13 from the second end;

[0034] In addition, the signal transmission line of the knob control module 2 and the electrical connection end 31 of the button control module 3 are extended through the wire along the channel 13 to the main control module in the riding lawn mower, and the button control module 3 is used to control the lifting and lowering of the mowing disc 7, the knob control module 2 is used to control the driving speed of the walking wheel 6, and the forward and backward pushing and pulling action of the tubular rod body 1 is used to control the driving direction of the walking wheel 6.

[0035] Based on the above technical solution, the joystick with control function includes a tubular rod body 1, a knob control module 2, and a button control module 3, which are respectively used to control the driving direction and driving speed of the traveling wheels 6 in the riding lawn mower, and the lifting and lowering of the mowing disc 7 in the riding lawn mower, making the control of the riding lawn mower more convenient, without the need to specially design a pedal for driving speed control at the footrest position of the vehicle body, freeing the user's legs and feet, making the control more centralized and convenient, and providing a better user experience.

[0036] In a preferred embodiment, the knob control module 2 is in the shape of an annular cylinder as a whole, and includes an inner cylinder ring 21 tightly mounted on the outer periphery of the annular mounting section 11 and an outer cylinder ring 22 rotatably mounted on the outer periphery of the inner cylinder ring 21, and the circumferential displacement of the outer cylinder ring 22 relative to the inner cylinder ring 21 is used as an electrical signal to control the travel speed of the walking wheel 6. Further, the peripheral wall of the annular mounting section 11 also has a through hole for passing the signal transmission line. Further, the outer periphery of the tubular rod body 1 is also engraved with an indicating arrow 12, and the outer peripheral wall of the outer cylinder ring 22 is engraved with a travel speed scale 24, which is used as a mechanical speedometer. Specifically, the riding lawn mower also has a display screen to indicate the current travel speed, and for the riding lawn mower, the general travel speed will not exceed 20 yards. For this solution, the walking wheel 6 can also be driven to move in the opposite direction by rotating the outer cylinder ring 22 in the opposite direction, which can be achieved by setting the program in the main control module (whether it can travel in the opposite direction) and driving the motor in the drive assembly. Conventionally, a limiter is designed on the rotation path of the outer cylinder ring 22 corresponding to the 0 vehicle speed to limit the possibility of further reverse rotation. When the forward rotation exceeds the position corresponding to the 0 vehicle speed, it corresponds to the state that the vehicle body starts and travels forward. On the contrary, when the reverse rotation exceeds the position corresponding to the 0 vehicle speed, it corresponds to the state that the vehicle body starts and travels reversely. That is, the marked position of the 0 vehicle speed is the start and stop control position of the drive motor.

[0037] In a preferred embodiment, the button control module 3 has a button 32 at one end away from the electrical connection end 31, which is used as a signal input component for controlling the lifting of the mowing disc 7. Furthermore, in the assembled state, the plane where the button is located on the outside is flush with the plane where the knob control module 2 is located on the outside, so that the overall structure is more compact.

[0038] As a further preferred embodiment, the tubular rod body 1 is in a "7" shape as a whole, and the upper bent portion thereof constitutes the second end of the tubular rod body 1, so as to facilitate user manipulation. Figure 2 As shown in FIG, a plurality of paddle structures 23 are protruded in an annular array on the outer peripheral wall of the outer cylinder ring 22 to facilitate the user to rotate the outer cylinder ring 22 .

[0039] Embodiment 2:

[0040] See also Figures 3 to 5 As shown in the figure, the riding lawn mower provided in this embodiment includes a body 4, two running wheels 6 distributed on both sides of the body 4, two drive assemblies for controlling the travel speed and travel direction of the running wheels 6 respectively, a mowing disc 7 arranged at a position below the body 4, and a main control module fixed in the body 4, and two joysticks with control functions as described in the above embodiment 1, and the joysticks can control the travel speed and travel direction of the running wheels 6, and control the lifting and lowering of the mowing disc 7.

[0041] This makes the operation of the riding mower more convenient, eliminating the need to specifically design a pedal for controlling the traveling speed at the footrest position of the vehicle body, freeing the user's legs and feet, making the operation more concentrated and convenient, and providing a better user experience.

[0042] In a preferred embodiment, the two joysticks are mirror - arranged and assembled on the main body 4 of the vehicle, and the first end of each joystick is respectively传动连接 (drivably connected) to a drive assembly. Specifically, the two joysticks respectively control the motor components of the two drive assemblies. Different pushing strokes (angles) of the joysticks cause different rotational speeds of the motors, thereby controlling straight - ahead, left - turn, right - turn, and reverse. This is mainly achieved through sensors. It should be noted that the control of the walking wheels 6 by pushing and pulling the joystick back and forth belongs to the prior art and is well - known to those skilled in the art, so the operating logic thereof is omitted here. The main technical point of this solution is to integrate the control switches originally arranged on the side console of the riding mower onto the joystick. In practical applications, the button control modules 3 of the two joysticks can respectively serve as the on - off switches for the motors corresponding to the mowing disc 7 and as the on - off switches for the motors in the two drive assemblies. However, one of the button control modules 3 on the joystick can also be used alone as the trigger for controlling the lowering of the mowing disc 7, and the other as the trigger for controlling the raising of the mowing disc 7 to make its lifting operation more convenient. At the same time, the rotational movement of the knob control module 2 includes the on - off control of the drive motor, but it is not limited to this.

[0043] As a further preferred embodiment, in combination with Figure 3 and Figure 5 as shown in, the main body 4 of the vehicle includes a seat 5 and a scissor - type lifting mechanism 41 arranged below the seat 5 and used to promote the lifting of the seat 5. The scissor - type lifting mechanism 41 forms two parallel support rods extending in the front - to - back direction, and chutes extending in the front - to - back direction are formed on the support rods. Two slide rails 42 adapted to the chutes are arranged below the seat 5, and a downward - facing toothed structure 43 is also arranged on one side of the slide rails 42. A "冂"-shaped lever 45 is horizontally arranged on the main body 4 of the vehicle, and two perforated plates 44 adapted to the toothed structure 43 are mirror - arranged on the lever 45 to unlock and lock the slide rails 42 by moving the lever 45 up and down.

[0044] Specifically, the main body 4 of the vehicle also has a spring or a tension spring for promoting the reset of the lever 45, and the middle of the lever 45 is hinged into a lever structure. By pulling up the lever 45 of the locking mechanism, the toothed structure 43 is disengaged from the perforated plate 44, allowing the seat 5 to move back and forth on the slide rails 42. When the lever 45 is released, under the action of the reset member (spring or tension spring), the toothed structure 43 is engaged with the perforated plate 44, and the seat 5 is locked at the current position on the slide rails 42.

[0045] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
