DETAILED DESCRIPTION

[0030] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0031] First embodiment

[0032] like Figure 1-Figure 3 As shown, the driving device of the golf cart of the first embodiment of the utility model comprises:

[0033] Frame 1;

[0034] The traveling mechanism includes traveling components arranged on both sides of the frame 1, and the traveling components include at least two wheels 2 distributed along the length direction of the frame 1 and a driving unit that drives the wheels 2 to rotate on the frame 1 around their own axis.

[0035] A power source 11 is also fixed on the frame 1, and the power source 11 is used to supply power to the driving source 3, so that the driving source 3 can drive the wheel 2 to rotate around its own axis to realize the driving function of the device.

[0036] Compared with the prior art, the utility model provides two travel components, and the driving sources 3 in the two travel components are independent of each other, and are respectively used to drive the corresponding wheels 2 to rotate, so as to realize the travel of the device. When the two driving sources 3 drive the wheels 2 on both sides to rotate at the same speed, the frame 1 can move straight, and when the two driving sources 3 drive the wheels 2 on both sides to rotate at different speeds, the frame 1 can turn. In particular, when the driving sources 3 can drive the wheels 2 on both sides to rotate in different directions, the device can turn sharply, greatly reducing the turning radius, thereby reducing the size requirements for the travel site, and at the same time, the shortening of the turning path can improve the travel efficiency of the golf cart.

[0037] A further improvement is that the travel assembly includes two wheels 2. Specifically, the number of wheels 2 in the travel assembly is two, which are respectively located at the two ends of one side of the frame 1. The two wheels 2 in the travel assembly are respectively the front wheel and the rear wheel. After adopting the above design, the number of wheels 2 is reduced, the cost is reduced, and the overall load of the travel device is reduced, which is conducive to improving the endurance.

[0038] A further improvement is that the drive unit includes a drive source 3, a driving wheel 4, a driven wheel 5 and a track 6, the drive source 3 is arranged on the frame 1 and the output end is connected to the driving wheel 4 by transmission, the driving wheel 4 and the driven wheel 5 are respectively connected to the coaxial centerline of the two wheels 2, and the driving wheel 4 is connected to the driven wheel 5 by transmission through the track 6.

[0039] Specifically, the driving source 3 includes a motor, the output end of the motor is fixedly connected to the driving wheel 4 and the front wheel coaxially, the driven wheel 5 is annular, and a transmission bearing 51 is arranged inside, the inner ring of the transmission bearing 51 is fixedly connected to the frame 1, and the outer ring is connected to the driven wheel 5 and the rear wheel coaxially through a concentric shaft 52. In this way, when the driving source 3 drives the driving wheel 4 to rotate, the driving wheel 4 drives the driven wheel 5 to rotate through the track 6 under the support of the transmission bearing 51, so that the rear wheel rotates, that is, in the traveling component, the driving source 3 can drive the two wheels 2 to rotate at the same time.

[0040] A further improvement is that the crawler belt 6 is a synchronous belt, and the driving wheel 4 and the driven wheel 5 are both I-shaped wheels. After adopting the above improvement, the stable transmission between the driving wheel 4, the driven wheel 5 and the crawler belt 6 can be guaranteed.

[0041] Second embodiment

[0042] like Figure 4-Figure 7As shown, the driving device of the golf cart according to the second embodiment of the utility model is based on the first embodiment, but differs in that it further comprises a tensioning assembly, and the tensioning assembly applies pressure on the crawler track 6 to tension the crawler track 6 .

[0043] By tensioning the crawler track 6 through the tensioning assembly, stable transmission between the driving wheel 4, the driven wheel 5 and the crawler track 6 can be ensured, so that the two wheels 2 in the traveling assembly rotate simultaneously.

[0044] Specifically, the tensioning assembly applies pressure to the circumferential outer wall of the crawler 6 from the outer side of the crawler 6. Since the crawler 6 is a synchronous belt, it is more convenient to apply pressure to the crawler 6 from the outer side of the crawler 6 to ensure the tension of the crawler 6, compared with applying pressure to the inner side of the crawler 6 to tension the crawler 6.

[0045] More specifically, the tensioning assembly includes a pressure member 7 and an adjusting unit 8. The pressure member 7 abuts against the track 6 and is connected to the vehicle frame 1 through the adjusting unit 8. The adjusting unit 8 is used to adjust the position of the pressure member 7 to tension the track 6. The position of the pressure member 7 is adjusted by the adjusting unit 8 so that the pressure member 7 abuts against the outer surface of the track 6, thereby tensioning the track 6.

[0046] In order to reduce the friction between the pressure member 7 and the track 6, the pressure member 7 includes a pressure wheel 71 abutting against the track 6, the axis of the pressure wheel 71 is consistent with the width direction of the track 6, and the pressure wheel 71 is rotatable around its own axis. The pressure member 7 also includes a pressure frame 72, and the pressure wheel 71 rotates on the pressure frame 72 and the circumferential outer edge is in contact with the outer surface of the track 6. The pressure wheel 71 abuts against the upper surface of the track 6. In this way, while the pressure wheel 71 abuts against the outer surface of the track 6, the friction between it and the track 6 can be reduced through its own rotation.

[0047] A further improvement is that the adjustment unit 8 includes an adjustment screw 83 that rotates on the frame 1 around its own axis and a screw sleeve 84 that is threadedly connected to the adjustment screw 83 . The screw sleeve 84 slides on the frame 1 along its own axis and is connected to the pressure member 7 .

[0048] Specifically, Figure 6 and Figure 7As shown, the adjusting unit 8 includes an inverted U-shaped adjusting frame 81, and the outer sides of the two ends of the adjusting frame 81 are integrally connected with extension plates, which are fixed to the frame 1 by fixing bolts 82; a through hole is provided at the top of the adjusting frame 81, and an adjusting bearing 85 is provided on the inner side of the through hole, and an adjusting screw 83 whose axial direction is parallel to the vertical direction is provided on the inner side of the adjusting bearing 85, the outer ring of the adjusting bearing 85 is fixedly connected to the adjusting frame 81, and the inner ring is fixedly connected to the adjusting screw 83, a screw sleeve 84 is provided on the inner side of the adjusting frame 81, and the screw sleeve 84 is threadedly connected to the lower part of the adjusting screw 83, and a cross plate 841 is provided at the bottom of the screw sleeve 84, and the two ends of the cross plate 841 are fitted with the inner walls of the two sides of the adjusting frame 81, and a sliding mouth 811 extending along the vertical direction is provided on the two side walls of the adjusting frame 81, and a slider 842 is slid on the inner side of the sliding mouth 811, and the slider 842 is integrally connected with the cross plate 841, and the pressure frame 72 is fixed below the cross plate 841.

[0049] After adopting the above structure, the adjusting screw 83 is rotated under the support of the adjusting bearing 85, so that the adjusting screw 83 acts on the screw sleeve 84 through the thread, and under the sliding cooperation of the slider 842 and the sliding mouth 811, the screw sleeve 84 and the cross plate 841 move in the vertical direction, and then the height position of the pressure wheel 71 is changed through the pressure frame 72, so that the pressure wheel 71 can abut against the upper surface of the track 6, and pressurize the track 6 to tighten the track 6, thereby ensuring its stable transmission with the driving wheel 4 and the driven wheel 5.

[0050] Third embodiment

[0051] like Figure 8 and Fig. 9 As shown, the driving device of the golf cart in the third embodiment of the utility model is based on the second embodiment, and the difference is that the tensioning assembly includes an adjusting screw 83 and a bearing seat 86. Among the two wheels 2, the axis line position of one wheel 2 is fixed, and the other is connected to the bearing seat 86. The bearing seat 86 slides on the frame 1 along the distribution direction of the two wheels 2. The axial direction of the adjusting screw 83 is parallel to the sliding direction of the bearing seat 86. The adjusting screw 83 is threadedly connected to the frame 1 and abuts against the bearing seat 86.

[0052] Specifically, in this embodiment, the axis line position of the front wheel is fixed, and the transmission bearing 51 corresponding to the rear wheel is connected to the bearing seat 86; the rear part of the frame 1 is provided with a square tube 12 extending along the width direction of the frame 1, and both sides of the bearing seat 86 are provided with a sliding base 13, the sliding base 13 is fixedly connected to the square tube 12, and a strip opening extending along the length direction of the frame 1 is provided on the sliding base 13.

[0053] 131, the bearing seat 86 slides inside the strip opening 131, the adjusting screw 83 is located between the front wheel and the bearing seat 86, and the axial direction is parallel to the length direction of the frame 1, one end of the adjusting screw 83 is located in the square tube 12, and the other end passes through the square tube 12 and abuts against the bearing seat 86, and the adjusting screw 83 is threadedly connected to the square tube 12.

[0054] After adopting the above structure, one end of the adjusting screw 83 away from the bearing seat 86 is hidden in the square tube 12, and the other end is abutted against the bearing seat 86. By rotating the adjusting screw 83, the pressure on the bearing seat 86 is increased, so that the bearing seat 86 is moved away from the front wheel along the strip opening 131, thereby driving the rear wheel away from the front wheel and tightening the track 6, thereby achieving the same technical effect as the second embodiment. Compared with the second embodiment, the tensioning assembly structure is more compact.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
