In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0029] The following will be described in combination with Figures 1 to 5 The electric sliding saddle mechanism and the sliding adjusting method thereof are described.

[0030] One embodiment of the present application provides an electric sliding saddle mechanism, referring to Figure 1 As shown in the figure, it comprises two parallel slide rails 1, a moving support 2, a saddle body 3 and a driving mechanism 4, and a plurality of locking grooves 11 are uniformly arranged on the slide rails 1; the moving support 2 is slidingly installed on the slide rails 1, and a locking device is arranged on the moving support 2, which is adapted to switch between a locking state and an unlocking state, in the locking state, the locking device cooperates with the locking grooves 11 to form a lock; in the unlocking state, the locking device is separated from the locking grooves 11; the saddle body 3 is fixed to the moving support 2; the driving mechanism 4 is connected to the moving support 2 and is adapted to drive the moving support 2 to slide on the slide rails 1.

[0031] In combination with Figure 2As shown, it can be understood that the electric sliding saddle mechanism of the embodiment can drive the moving support 2 and the saddle body 3 to move forward and backward on the slide rail 1 through the driving mechanism 4. The moving support 2 and the saddle body 3 can be locked at any time during the movement on the slide rail 1 through the locking device cooperating with the locking groove 11, so that the moving support 2 and the saddle body 3 are at the required position. The operator can control the driving mechanism 4 and the locking device to adjust the position of the sliding saddle, so as to adjust the mounting position of the sliding saddle on the whole vehicle. The electric sliding saddle mechanism of the embodiment can adjust the position of the saddle body 3 on the slide rail 1 at any position, which is simple and convenient, and only one operator is needed to complete the whole adjustment process, so that the precise adjustment of the sliding saddle is realized.

[0032] In some examples, the two ends of the two slide rails 1 are connected through the cross beams 7 respectively. It can be understood that the sliding saddle will reduce the torsional strength of the whole vehicle due to the lack of left and right connecting members. In the example, the two ends of the two slide rails 1 are connected through the two cross beams 7 respectively, which strengthens the torsional effect of the overall structure.

[0033] In some embodiments of the electric sliding saddle mechanism of the application, in combination with Figure 3 and Figure 4 As shown, the slide rail 1 is a T-shaped slide rail, the moving support 2 includes a sliding part 21 and a connecting part 22, the sliding part 21 is provided with a T-shaped groove 211 at the bottom, the T-shaped groove 211 is suitable for cooperating with the slide rail 1 for installation, and the locking device is arranged on one side of the T-shaped groove 211; the connecting part 22 is located at the top of the sliding part 21 and is used for fixedly connecting the saddle body 3.

[0034] It can be understood that the moving support 2 is connected with the slide rail 1 through the T-shaped groove 211 at the bottom of the connecting part 22, so that the moving support 2 can slide along the slide rail 1. The locking device arranged on one side of the T-shaped groove 211 can cooperate with the locking groove 11 on the slide rail 1 for locking, the connecting part 22 of the moving support 2 is used for fixing the saddle body 3, and the saddle body 3 can be locked at the required position through the cooperation of the locking device and the locking groove 11.

[0035] In some embodiments of the electric sliding saddle mechanism of the application, the locking device includes a locking shaft 23, a plurality of locking blocks 24 and a locking motor 25, the locking shaft 23 is rotatably arranged on one side of the T-shaped groove 211; the plurality of locking blocks 24 are fixedly sleeved on the locking shaft 23, the interval between adjacent two locking blocks 24 is consistent with the interval between adjacent two locking grooves 11 on the slide rail 1; and the locking motor 25 is connected to the locking shaft 23 and drives the locking shaft 23 to deflect, so that the locking blocks 24 move towards or away from the locking groove 11.

[0036] It can be understood that the embodiment mainly provides a specific implementation structure of the locking device, in combination with Figure 2 andFigure 3 As shown, the locking motor 25 drives the locking shaft 23 to deflect. Multiple locking blocks 24 are fixedly mounted on the locking shaft 23. The spacing between the locking blocks 24 is the same as the spacing between the locking grooves 11, allowing the locking blocks 24 to insert into the locking grooves 11. When the movable support 2 moves to the desired position on the slide rail 1, the locking motor 25 is activated to drive the locking shaft 23 to deflect. The locking shaft 23 drives the locking blocks 24 to deflect and enter the locking grooves 11, thus locking the movable support 2 on the slide rail 1. When unlocking is required, the locking motor 25 is activated to drive the locking shaft 23 to deflect in the opposite direction. The locking shaft 23 drives the locking blocks 24 to disengage from the locking grooves 11, thus unlocking the movable support 2 and the slide rail 1.

[0037] In some embodiments of the electric sliding saddle mechanism of the present invention, combined with Figure 2 and Figure 3 As shown, the sliding part 21 is provided with a threaded hole 212 that passes through the sliding part 21. The drive mechanism 4 includes a gearbox 41, a drive motor 42 and a lead screw 43. The gearbox 41 is fixed to one end of the slide rail 1. The drive motor 42 is connected to the gearbox 41 and is used as the power input of the gearbox 41. The lead screw 43 passes through the threaded hole 212 and is connected to the gearbox 41 to obtain rotational power.

[0038] It is understandable that the drive motor 42 outputs power, which drives the lead screw 43 to rotate through the gearbox 41. The lead screw 43 passes through the threaded hole 212 of the movable support 2. As the lead screw 43 rotates, the rotation of the lead screw 43 can be converted into the sliding of the movable support 2 on the slide rail 1, thereby adjusting the forward and backward movement position of the saddle body 3.

[0039] Furthermore, a speed reduction and torque amplification structure is provided within the gearbox 41. It's important to understand that speed reduction and torque amplification is a common mechanical transmission principle. By reducing the rotational speed, torque is increased, thereby achieving precise control and efficient transmission of mechanical equipment. In mechanical transmission systems, gears, belts, sprockets, and other transmission devices are commonly used to achieve speed reduction and torque amplification. Among these, gear transmission is the most widespread form. By using gear sets of different sizes, speed reduction and torque amplification can be achieved. When the input gear's rotational speed is high, the output gear's rotational speed will decrease accordingly, but the output gear's torque will increase accordingly, achieving speed reduction and torque amplification. In this embodiment, the speed reduction and torque amplification structure can employ gear sets of different sizes and forms, which can reduce the required output torque of the drive motor 42.

[0040] In some examples, the other end of the slide rail 1 is provided with a screw fixing block 5 for supporting the screw rod 43, and the fixing hole of the screw fixing block 5 is equipped with a bearing 51 and a rubber support ring 52. It can be understood that the screw rod 43 is rotatably arranged between the screw fixing block 5 and the gear box 41, and the fixing hole of the screw fixing block 5 is equipped with a bearing 51 and a rubber support ring 52. The bearing 51 can reduce wear and improve transmission efficiency; the screw rod 43 is stationary, the saddle body 3 is fixed, and a larger impact will be transmitted to the screw rod 43 during the operation of the vehicle. The locking device locks the position of the saddle body 3, reducing the impact on the screw rod 43, and the rubber support ring 52 on the screw fixing block 5 can also reduce the impact of the saddle body 3 on the screw rod 43, reducing damage to the screw rod 43 and improving the service life.

[0041] Based on the structure of the above several embodiments, in another embodiment of the electric sliding saddle mechanism of the present application, the electric sliding saddle mechanism further comprises a central control display screen for controlling the locking device and the driving mechanism 4. It can be understood that the control part of the electric sliding saddle mechanism of the present embodiment is integrated in the central control display screen, and the central control display screen can be in the central control system of the vehicle. By realizing the control and adjustment of the locking device and the driving mechanism 4 on the central control display screen, one operator can complete the entire adjustment process of the electric sliding saddle mechanism, and the purpose of accurate adjustment is achieved.

[0042] Specifically, in some examples, the moving support 2 is also provided with a position sensor 6 which is electrically connected with the central control display screen. The position sensor 6 can be used for zero calibration and moving distance calibration of the moving support 2, and can real-time master the moving position of the moving support 2. For details, please refer to the sliding adjustment method of the electric sliding saddle mechanism described later.

[0043] In some embodiments, the method for adjusting the sliding of the electric sliding saddle mechanism comprises the following steps: zero calibration and swing angle calibration of the locking device, determination of the initial state of the locking device in the unlocked state and the swing angle amplitude of switching to the locked state, and recording of the data on the central control display screen; driving the mobile support 2 to slide to one end of the slide rail 1, locking the locking device with the locking groove 11 on the slide rail 1, and using the position sensor 6 to calibrate the zero position of the mobile support 2 and record the calibration data on the central control display screen; unlocking the locking device and the locking groove 11 on the slide rail 1, driving the mobile support 2 to slide to the other end of the slide rail 1, and calibrating the moving distance during the sliding process and recording the calibration data on the central control display screen; adjusting the mobile support 2 to slide to the required position on the slide rail 1 based on the zero calibration data and the moving distance calibration data of the mobile support 2 through the central control display screen; and adjusting the locking device to lock or unlock the mobile support 2 based on the zero calibration and swing angle calibration data of the locking device through the central control display screen.

[0044] It can be understood that after the electric sliding saddle mechanism is installed, the zero calibration and swing angle calibration of the locking motor 25 are first performed, the locking motor 25 drives the locking shaft 23 to rotate, the locking block 24 is deflected, the locking block 24 and the locking groove 11 on the slide rail 1 are separated, and the locking motor 25 corresponding to the deflection angle of the locking block 24 from the separation to the locking position is calibrated to zero.

[0045] After the zero calibration and swing angle calibration of the locking motor 25 are completed, the mobile support 2 is pushed to the rear end, the locking motor 25 drives the locking block 24 to lock the mobile support 2, at this time the saddle body is locked and fixed, the position sensor 6 at the front end of the mobile support 2 is used to calibrate the zero position of the mobile support 2, after the zero position calibration of the mobile support 2 is completed, the locking device and the locking groove 11 on the slide rail 1 are unlocked, the mobile support 2 is pushed to the front end, and the moving distance is calibrated according to the moving distance.

[0046] The control part of the electric sliding saddle mechanism is integrated in the central control display screen of the vehicle, and the above-mentioned calibration data need to be stored and recorded in the central control display screen. After the overall calibration is completed, the driver can adjust the front and rear positions of the saddle body 3 through the central control function of the central control display screen. The adjustment unit range depends on the installation interval of the locking block 24, and the locking of the saddle body 3 needs to rely on the locking of the locking block 24. The length that the driver can adjust when operating the saddle body 3 to move must be an integer multiple of the installation interval of the locking block 24, otherwise it cannot be correctly locked. Specifically, the adjustment distance can be displayed on the central control display screen, and each adjustment distance is an integer multiple of the installation interval of the locking block 24. It should be understood that when the adjustment function is abnormal, the locking of the locking device of the electric sliding saddle mechanism is prior to unlocking, so as to ensure that the saddle body 3 will not slide, and at the same time, a function abnormality prompt will be given to the driver for checking.

[0047] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
