[0070] Embodiment 1

[0071] As shown in FIGS. 1-7, a foldable electric golf bag car, when folding the electric golf bag car, the connecting rods 5 on both sides of the frame 2 of the electric golf bag car and the wheels connected with the connecting rods 5 can be folded on both sides of the frame 2.

[0072] In this embodiment, the electric golf bag car is a four-wheel golf bag car.

[0073] Specifically, the four-wheel golf bag car includes a frame 2, two front wheels 3 installed at the front end of the frame 2 through a front wheel frame 4, connecting rods 5 arranged on both sides of the rear end of the frame 2, rear wheels 1 arranged at the outer end of the connecting rods 5, support wheels 26 arranged on the rear side of the frame 2, and a main pipe assembly arranged on the frame 2, the main pipe assembly including a lower main pipe 6 and an upper main pipe 7, and a handle 8 located at the top of the upper main pipe 7.

[0074] In order to realize the folding of the electric golf main pipe assembly, the connecting rods 5 on both sides of the frame 2 and the wheels connected with the connecting rods 5 are synchronously driven to fold on both sides of the frame 2.

[0075] Specifically, the lower main pipe 6 of the main pipe assembly is rotated forward to fold above the frame 2, synchronously driving the connecting rods 5 to rotate forward to fold on both sides of the frame 2 and the wheels connected with the connecting rods 5 to fold on the outer side of the corresponding connecting rods 5.

[0076] In this embodiment, when folding the lower main pipe 6, the connecting rods 5 connected with the rear wheels 1 are rotated forward to fold on both sides of the frame 2, and the two rear wheels 1 are folded on the outer side of the connecting rods 5 connected therewith.

[0077] As shown in FIGS. 2-3, in order to drive the folding of the connecting rods 5 by the folding of the lower main pipe 6, the lower main pipe 6 is linked with the connecting rods 5 through a gear.

[0078] Specifically, the lower end of the lower main pipe 6 is provided with a bevel gear I 9 on both sides, and the end of the connecting rod 5 towards the frame 2 is provided with a bevel gear II 10 engaged with the bevel gear I 9, and the other end of the connecting rod 5 and the wheel assembly connected thereto are hinged.

[0079] As shown in Figure 3, the rear side of the frame 2 is provided with a lower locking wrench 23, the inner side of the lower locking wrench 23 is provided with a locking plate 24 rotatably assembled in the frame, and the outer ring surface of the bevel gear I 9 is provided with two locking notches 25 capable of cooperating with the locking plate 24, and corresponding to the unfolded state and folded state of the electric golf bag vehicle respectively.

[0080] Corresponding arc-shaped through holes 34 are provided on the two locking plates 24, transverse locking pins 35 are provided in the two arc-shaped through holes 34, and the lower end of the lower main pipe 6 is provided with a locking bayonet 36 cooperating with the locking pin 35. When the electric golf bag vehicle is in the folded or unfolded state, the locking pin 35 is located in the locking bayonet 36 to limit the lower main pipe 6, ensuring the stability of the electric golf bag vehicle in the folded or unfolded state.

[0081] When operating the electric golf bag vehicle to unfold or fold, the user rotates the lower locking wrench 23 upward to drive the locking plate 24 away from the bevel gear I 9, at the same time, the locking plate 24 drives the locking pin 35 to move backward and out of the locking bayonet 36, at this time, the lower main pipe 6 can be rotated upward to unfold the electric golf bag vehicle, or rotated downward to fold the electric golf bag vehicle. After rotating in place, the lower locking wrench 23 is rotated downward, at this time, the locking plate 24 can be clamped in the corresponding locking notch 25, and the locking pin 35 can be clamped in the locking bayonet 36, so that the lower main pipe 6 can be locked, ensuring the stability of the electric golf bag vehicle in the unfolded or folded state.

[0082] Wherein, when rotating the locking plate 24, the arc-shaped through hole 34 can push the locking pin 35 to move, and the frame 2 on the outer side of the locking plate 24 is provided with a waist-shaped hole, the two ends of the locking pin 35 are fitted in the waist-shaped hole, and the waist-shaped hole guides the movement of the locking pin 35.

[0083] When the electric golf bag vehicle needs to be folded or unfolded, the user rotates the lower locking wrench 23 upward to drive the locking plate 24 away from the bevel gear I 9, at this time, the bevel gear I 9 can be rotated by the lower main pipe 6 to realize the synchronous folding or unfolding of the lower main pipe 6, the connecting rod 5 and the rear wheel 1; after unfolding or folding in place, the lower locking wrench 23 is rotated downward, at this time, the locking plate 24 can be clamped in the corresponding locking notch 25 to lock the bevel gear I 9, so that the lower main pipe 6 cannot be rotated, ensuring the stability of the electric golf bag vehicle in the unfolded or folded state.

[0084] The linkage structure between the lower main pipe 6 and the connecting rod 5 is not limited to the above-mentioned bevel gear cooperation mode.

[0085] In the embodiment, the wheel assembly is a rear wheel assembly.

[0086] In order to drive the movement of the electric golf bag vehicle, i.e. four-wheel golf bag vehicle, at least one wheel of the electric golf bag vehicle is internally provided with a wheel-embedded power system 11 for driving the electric golf bag vehicle.

[0087] The wheel-embedded power system 11 is installed in any at least one wheel, i.e. any at least one rear wheel 1, on both sides of the rear end of the vehicle frame 2.

[0088] The wheel-embedded power system 11, i.e. the power system is installed in the space D formed inside the corresponding wheel, but is not limited to the way that the power system is completely arranged in the space D, and a small part of the power system can be allowed to exceed the space D formed by the wheel.

[0089] In the embodiment, the wheel-embedded power system 11 is respectively installed in the two rear wheels 1 of the four-wheel golf bag vehicle, and the rear wheel assembly includes the rear wheel 1 and the wheel-embedded power system 11 located inside the rear wheel 1, and the wheel-embedded power system 11 is located inside the corresponding rear wheel 1, i.e. the side of the rear wheel 1 facing the vehicle frame 2.

[0090] Specifically, the wheel-embedded power system 11 includes a box body 11-1, the inner side of the box body 11-1 is provided with a connecting groove 11-2, and the outer end of the connecting rod 5 is hinged in the connecting groove 11-2, which can facilitate the folding of the two rear wheels 1 by the connecting rod 5 when the four-wheel golf bag vehicle is folded.

[0091] Preferably, in order to ensure the stability of the connection between the rear wheel assembly and the vehicle frame 2, two hinge rods 11-3 are arranged in the connecting groove 11-2, and the rear side of the connecting rod 5 is provided with an auxiliary connecting rod 12 parallel thereto, and the outer ends of the two are hingedly connected to the two hinge rods 11-3 in the connecting groove 11-2.

[0092] The bevel gear II 10 at the inner end of the connecting rod 5 cooperates with the bevel gear I 9 at the bottom of the lower main pipe 6, and the inner end of the auxiliary connecting rod 12 is directly hinged to the vehicle frame 2.

[0093] The wheel-embedded power system 11 can also be installed on the outer side of the corresponding rear wheel 1, i.e. the side of the rear wheel 1 away from the vehicle frame, in which case the connecting rod 5 cannot be connected to the box body 11-1, and in this case, the rear wheel assembly further includes a separate hinge seat 13 arranged on the inner side of the rear wheel 1, so as to be hingedly connected to the connecting rod 5 and the auxiliary connecting rod 12.

[0094] In the embodiment, the upper main pipe 7 and the lower main pipe 6 are hingedly connected to facilitate folding and unfolding of the two.

[0095] As shown in Fig. 4, in particular, three parallel arranged hinged plates I 14 are arranged on the connecting part I of the lower end of the upper main pipe 7, and two parallel arranged hinged plates II 15 are arranged on the connecting part II of the upper end of the lower main pipe 6, the two hinged plates II 15 are respectively matched in the gap between the adjacent two hinged plates I 14, and a connecting shaft 16 is arranged through the center, so that the hinged plates I 14 and the hinged plates II 15 are rotatably matched on the connecting shaft 16.

[0096] The outer side of the two hinged plates I 14 arranged on the outer side is provided with an annular segmented clamping groove, and a lock block 17 with a locking tooth surface on the inner side is rotatably arranged in the clamping groove. Due to the arrangement of the clamping groove, the lock block 17 cannot rotate relative to the hinged plate I 14. The outer side of the hinged plate II 15 is provided with a secondary tooth surface matched with the locking tooth surface, one end of the connecting shaft 16 is provided with a rotatable lower locking wrench 18, and the other end is threadedly connected with the lock block 17 on the side.

[0097] The outer side of the lock block 17 is respectively provided with a cover plate 19 fixedly connected therewith, and the cover plate 19 on the side where the lower locking wrench 18 is arranged is provided with a wrench limiting groove 20.

[0098] When folding the upper main pipe 7 and the lower main pipe 6, the lower locking wrench 18 is turned to make it in the axial direction of the connecting shaft 16, the connecting shaft 16 is rotated by the lower locking wrench 18 to move towards the side where the lower locking wrench 18 is arranged, so that the locking tooth surface on the lock block 17 is separated from the corresponding secondary tooth surface, and the hinged plate I 14 can rotate relative to the hinged plate II 15. At this time, the upper main pipe 7 can be rotated downward around the top of the lower main pipe 6 to be folded on the rear side of the lower main pipe 6, and when the lower main pipe 6 is folded forward above the vehicle frame 2, the upper main pipe 7 is above the lower main pipe 6. During the folding of the lower main pipe 6, the connecting rod 5 and the rear wheel 1 can be folded on both sides of the vehicle frame 2, so that the folding of the entire electric golf cart is completed.

[0099] When unfolding the golf cart, the connecting shaft 16 is moved to the end away from the lower locking wrench 18, and after the locking tooth surface is engaged with the corresponding secondary tooth surface, the lower locking wrench 18 is turned to be perpendicular to the axial direction of the connecting shaft 16 and is matched in the wrench limiting groove 20. At this time, the connection between the upper main pipe 7 and the lower main pipe 6 can be locked.

[0100] The folding mode of the upper main pipe 7 and the lower main pipe 6 is not limited to the above mode, and other folding modes can also be used, such as folding the upper main pipe 7 into the lower main pipe 6 in an extendable and retractable manner.

[0101] As shown in Figs. 5-6, in order to drive the rear wheel 1 to rotate by the wheel built-in power system 11, the wheel built-in power system 11 comprises a motor 11-4 and a worm gear 11-5 engaged with an output worm 11-6 of the motor 11-4, a core shaft 11-7 of the worm gear 11-5 is connected with a wheel hub of the wheel built-in power system 11.

[0102] The motor 11-4 is a brushless motor.

[0103] Compared with a brush motor with the same power, the brushless motor adopted in the present application has a smaller size, so that the structure of the whole wheel built-in power system 11 is more compact, and the wheel built-in power system 11 is more convenient to be built in the wheel.

[0104] In the present embodiment, in order to protect the worm gear 11-5 and the matching part of the output worm 11-6, the worm gear 11-5 is installed in a box 11-1. The core shaft 11-7 of the worm gear 11-5 is directly connected with the corresponding wheel hub of the rear wheel 1 by penetrating out of one side of the box 11-1. The core shaft 11-7 is matched with the box 11-1 through a bearing I 11-8. A side cover plate 11-9 is arranged on the side of the box 11-1 where the bearing I 11-8 is located, and the side cover plate 11-9 is connected with the box 11-1 through bolts. The worm gear 11-5 and the bearing I 11-8 can be conveniently installed by dismounting the side cover plate 11-9.

[0105] In the present embodiment, the motor 11-4 is installed on the upper side of the rear side of the box 11-1 through bolts, and the front end of the output worm 11-6 is matched with the box 11-1 through a bearing II 11-10.

[0106] A cover 11-11 is arranged on the front side of the box 11-1 and connected with the box 11-1 through bolts. The bearing II 11-10 can be conveniently installed by dismounting the cover 11-11.

[0107] Preferably, in order to achieve good heat dissipation of the motor 11-4, a heat dissipation cavity 11-12 is arranged outside the motor 11-4, a plurality of heat dissipation fins are arranged in the heat dissipation cavity 11-12, and a heat dissipation window 11-13 matched with the heat dissipation cavity 11-12 is arranged on the box 11-1.

[0108] Specifically, the box 11-1 comprises a cavity for accommodating the worm gear 11-5 and a support seat arranged on the rear side of the cavity for supporting the motor 11-4. The motor 11-4 is installed on the support seat, and the heat dissipation window 11-13 is arranged on the rear wall of the support seat.

[0109] The wheel built-in power system 11 disclosed in the present embodiment can be in a form without the heat dissipation cavity 11-12 or in a form with the heat dissipation cavity 11-12.

[0110] The wheel built-in power system 11 of the embodiment adopts the transmission mode of the output worm 11-6 and the worm wheel 11-5, which not only facilitates the connection of the entire wheel built-in power system 11 and the electric control system of the electric golf bag vehicle, thereby realizing the automatic control of the speed of the electric golf bag vehicle, but also enables the wheel built-in power system 11 to have a certain self-locking function, thereby avoiding the reverse rotation and ensuring the reliability of the transmission process and the safety of the electric golf bag vehicle during driving.

[0111] When the electric golf bag vehicle is descending, the speed of the vehicle can also be limited, that is, a descending speed is set, so that the speed of the vehicle will not exceed the set speed when descending on a slope with any slope, thereby effectively ensuring the safety of the electric golf bag vehicle.

[0112] Moreover, compared with the ordinary gear transmission deceleration assembly, the worm and worm wheel transmission deceleration mode has more excellent self-locking performance, thereby making the deceleration assembly of the embodiment have the following advantages:

[0113] First, once the transmission interface is powered off or has a mechanical failure, the deceleration assembly (that is, the cooperation of the worm and worm wheel) will be self-locked, effectively preventing the reverse rotation caused by external interference;

[0114] Second, the safety and reliability of the mechanical transmission can be ensured, and once a failure occurs, the transmission is immediately stopped, effectively avoiding the damage of the motor 11-4 and other components caused by mechanical damage.

[0115] Third, it also has good adjustment performance, and the output torque can be adjusted by changing the angle between the worm wheel 11-5 and the output worm 11-6.

[0116] In addition, compared with the hub motor, the wheel built-in power system 11 of the present application has a small overall volume and light weight, and adopts the cooperation of the output worm 11-6 and the worm wheel 11-5, which not only has small running noise, but also has a large reduction ratio, that is, has good deceleration function, can increase the driving torque through deceleration, and enables the electric golf bag vehicle to easily cope with uphill and other road conditions.

[0117] The wheel built-in power system 11 adopted in the embodiment has a small volume and light weight, and the torque can be transmitted to the corresponding wheel through the cooperation of the output worm 11-6 and the worm wheel 11-5, which has a simple and compact structure and good transmission effect.

[0118] Due to the ruggedness of the golf course, when the electric golf bag vehicle tilts backward and causes the front wheel 3 to be suspended when ascending, the supporting wheel 26 can support the electric golf bag vehicle to ensure its stability.

[0119] In the embodiment, the supporting wheels 26 are arranged at the rear side of the frame 2 through triangular supports 27, the two ends of the triangular supports 27 are hinged at the two sides of the rear end of the frame 2, and the supporting wheels 26 are installed at the rear end of the triangular supports 27.

[0120] In the embodiment, the battery cabin of the electric golf bag vehicle is arranged in the frame 2, the battery is an explosion-proof battery, and the battery is disassembled from the top of the frame 2.

[0121] As shown in FIG. 7, when the four-wheel golf bag vehicle of the embodiment is folded, the upper main pipe 7 rotates rearward and downward, so as to be folded with the lower main pipe 6, and the lower main pipe 6 rotates forward and downward, so as to be folded above the frame 2. When the lower main pipe 6 is folded, the connecting rod 5 rotates forward under the driving of the lower main pipe 6, so as to drive the rear wheels 1 connected thereto to be folded at the two sides of the frame 2, that is, the connecting rod 5 and the corresponding rear wheels 1 are attached to the side of the frame 2. The triangular support 27 is rotated downward and forward, so as to drive the supporting wheels 26 to be folded below the frame 2. This folding mode can effectively reduce the volume of the four-wheel golf bag vehicle after being folded, and is more convenient for moving and storing.

[0122] In the embodiment, the frame 2 is provided with a pad plate 33 at the rear side, which can cooperate with the two rear wheels 1. After the electric golf bag vehicle is folded, it is placed in a vertical manner, that is, the pad plate 33 and the two rear wheels 1 form a triangular support, so as to ensure the stability of the electric golf bag vehicle.

[0123] In the embodiment, the two rear wheels 1 of the four-wheel golf bag vehicle are provided with the wheel built-in power system 11. In addition, the wheel built-in power system 11 has the following arrangement modes:

[0124] (1) The wheel built-in power system 11 is installed in the single rear wheel 1;

[0125] (2) The wheel built-in power system 11 is installed in the single or double front wheels 3;

[0126] (3) The wheel built-in power system 11 is installed in the single front wheel 3 and the single rear wheel 1 (the same side front and rear wheels 1 or the non-same side front and rear wheels 1);

[0127] (4) The wheel built-in power system 11 is installed in the single front wheel 3 and the double rear wheels 1, or the double front wheels 3 and the single rear wheel 1;

[0128] (5) The wheel built-in power system 11 is installed in the double front wheels 3 and the double rear wheels 1.

[0129] Embodiment 2

[0130] As shown in Figs. 8-11, on the basis of Embodiment 1, this embodiment also provides a foldable electric golf bag vehicle, which has the same general structure as Embodiment 1, except that the folding and unfolding locking manner between the lower main pipe 6 and the vehicle frame 2 of the electric golf bag vehicle is different from that of Embodiment 1. Specifically,

[0131] In this embodiment, in order to achieve the unfolding locking of the lower main pipe 6, a pull locking assembly 37 is installed on the lower main pipe 6, and the vehicle frame 2 is provided with a locking hole 38 matched with the pull locking assembly 37, and the locking rod 37-1 of the pull locking assembly 37 extends into the corresponding locking hole 38 to lock the unfolded state of the lower main pipe 6.

[0132] The pull locking assembly 37 includes a pull handle 37-2, a locking rod 37-1 connected with the pull handle 37-2 and located at the bottom of the pull handle 37-2, and a lower reset spring 37-3 provided on the locking rod 37-1, and the lower end of the locking rod 37-1 can extend into the corresponding locking hole 38.

[0133] Specifically, the lower end of the lower main pipe 6 is provided with a mounting seat 39 at the matching position with the vehicle frame 2, and the pull handle 37-2 and the locking rod 37-1 are both mounted on the mounting seat 39, and the lower reset spring 37-3 is located in the mounting seat 39, and the lower end of the locking rod 37-1 extends from the bottom of the mounting seat 39.

[0134] During the unfolding process of the lower main pipe 6, the plane where the locking hole 38 is located will press the locking rod 37-1 upwards, and then compress the lower reset spring 37-3, until the locking rod 37-1 is opposite to the corresponding locking hole 38, at this time, the locking rod 37-1 will extend into the corresponding locking hole 38 under the elastic force of the lower reset spring 37-3, that is, the lower main pipe 6 can be locked so that it cannot be folded. If you need to fold the lower main pipe 6, you only need to pull the pull handle 37-2 upwards, and the locking rod 37-1 will move upwards with the pull handle 37-2 (this process will compress the lower reset spring 37-3), and then the locking rod 37-1 can be withdrawn from the corresponding locking hole 38, at this time, the lower main pipe 6 can be unlocked for rotating and folding operation.

[0135] In order to achieve the locking of the folded state of the lower main pipe 6, a pull locking assembly 37 is installed on the lower main pipe 6, and the vehicle frame 2 is provided with a locking hole 38 matched with the pull locking assembly 37, and the locking rod 37-1 of the pull locking assembly 37 extends into the corresponding locking hole 38 to lock the unfolded state of the lower main pipe 6.

[0136] The pull locking assembly 37 includes a pull handle 37-2, a locking rod 37-1 connected with the pull handle 37-2 and located at the bottom of the pull handle 37-2, and a lower reset spring 37-3 provided on the locking rod 37-1, and the lower end of the locking rod 37-1 can extend into the corresponding locking hole 38.

[0137] Specifically, the locking block 41-1 is in H-shaped structure, the push block 41-4 at the rear side of the locking wrench 41-2 is clamped in the notch at the bottom of the locking block 41-1, and the forward pushing of the locking wrench 41-2 can drive the lower end of the locking block 41-1 to rotate forward and upward. The front end of the frame 2 is provided with a protrusion 43 pointing forward, and the locking slot 42 is located at the bottom of the protrusion 43.

[0138] During the folding of the lower main pipe 6, the locking block 41-1 will move upward under the pushing of the protrusion 43 and compress the upper reset spring 41-3 until the locking block 41-1 rotates to the front side of the protrusion 43, at which time the locking block 41-1 is clamped in the locking slot 42 at the bottom of the protrusion 43 under the elastic force of the upper reset spring 41-3, that is, the lower main pipe 6 is locked and cannot be unfolded. If the lower main pipe 6 needs to be unfolded, only the upper end of the locking wrench 41-2 needs to be pushed, which will push the lower end of the locking block 41-1 to move forward and upward (this process will compress the upper reset spring 41-3), so that it is separated from the locking slot 42, at which time the lower main pipe 6 can be unlocked and unfolded.

[0139] Preferably, in order to facilitate the cooperation of the locking block 41-1 with the locking slot 42 during the folding of the lower main pipe 6, the lower end of the locking block 41-1 is in the shape of a front high-thick bottom inclined surface.

[0140] The unfolding and locking method disclosed in this embodiment is simple in structure and very convenient to operate.

[0141] As can be seen from the linkage mode of the rear wheel 1 and the lower main pipe 6 in Embodiment 1, when the lower main pipe 6 is unfolded, the connecting rod 5 can be used to unfold the rear wheel 1 at the same time, and when the lower main pipe 6 is folded, the connecting rod 5 can be used to fold the rear wheel 1 at the same time. Therefore, the locking of the lower main pipe 6 in this embodiment can also achieve the locking of the rear wheel 1 in the folded or unfolded state. In addition, the folding and unfolding locking between the lower main pipe 6 and the upper main pipe 7 adopts the mode in Embodiment 1.

[0142] Moreover, the electric golf bag car in this embodiment adopts the structure of the supporting wheel 26 and the assembly mode of the battery 45 in Embodiment 5.

[0143] Embodiment 3

[0144] As shown in FIGS. 12-13, on the basis of Embodiment 1, this embodiment also provides a foldable electric golf bag car, which has the same general structure as Embodiment 1, except that:

[0145] In order to improve the parking function of the wheel built-in power system 11 and ensure the safety of the electric golf bag car when parking, the wheel built-in power system 11 further comprises a parking assembly connected with the end of the output worm 11-6.

[0146] In order to realize the parking effect, the parking assembly comprises a friction plate 11-14 connected with the output worm 11-6, and a brake plate 11-15 capable of locking the friction plate 11-14.

[0147] When the electric golf bag car is running, the output worm 11-6 can drive the friction plate 11-14 to rotate synchronously, and when parking, the brake plate 11-15 moves towards the friction plate 11-14 and can lock the friction plate 11-14 to prevent it from rotating, so that the output worm 11-6 cannot rotate, achieving the purpose of parking.

[0148] Specifically, in order to realize the connection between the output worm 11-6 and the friction plate 11-14, the output worm 11-6 is provided with a pin hole 11-16, and the friction plate 11-14 is connected with the output worm 11-6 through a pin (not shown in the figure) installed in the pin hole 11-16.

[0149] Among them, the inner hole of the friction plate 11-14 has two accommodating notches 11-17 symmetrically arranged on the outer periphery and communicating with the inner hole, when the output worm 11-6 with the pin assembled is matched in the inner hole of the friction plate 11-14, the two ends of the pin are located in the two accommodating notches 11-17, and when the output worm 11-6 rotates, the pin can be used to drive the friction plate 11-14 to rotate synchronously.

[0150] In order to drive the brake plate 11-15 to lock the friction plate 11-14, the parking assembly further comprises a brake stator 11-18, the brake plate 11-15 is located on the inner side of the brake stator 11-18, the friction plate 11-14 is installed on the side of the brake stator 11-18 facing the brake plate 11-15, and the brake stator 11-18 is wound with a coil 11-19.

[0151] Specifically, the brake stator 11-18 is provided with an annular cavity, an annular groove-shaped support 11-20 with an outward opening is arranged in the annular cavity, and the coil 11-19 is wound in the annular groove-shaped support 11-20.

[0152] The end of the inner hole of the brake stator 11-18 facing the brake plate 11-15 is an installation cavity with a larger inner diameter than the inner hole, and the friction plate 11-14 is placed in the installation cavity.

[0153] When the coil 11-19 is energized, the brake stator 11-18 becomes a magnet with magnetic force, which attracts the brake pad 11-15, so as to clamp the friction plate 11-14 between the brake pad 11-15 and the brake stator 11-18, preventing the friction plate 11-14 from rotating with the output worm 11-6.

[0154] Preferably, the brake stator 11-18 is provided with a wire passing notch on the outer ring surface, so as to facilitate the end of the coil 11-19 to be led out and connected to the power supply.

[0155] In order to realize the inward movement of the brake pad 11-15 for resetting when the parking is released, the brake stator 11-18 is provided with a reset spring 11-21 on the side facing the brake pad 11-15.

[0156] Specifically, the brake stator 11-18 is provided with a mounting hole I on the side facing the brake pad 11-15, and the reset spring 11-21 is placed in the mounting hole I.

[0157] When the coil 11-19 is energized, the brake pad 11-15 moves towards the brake stator 11-18 and clamps the friction plate 11-14, which will compress the reset spring 11-21. After the coil 11-19 is de-energized, the brake stator 11-18 loses the magnetic force, and the brake pad 11-15 moves inwardly, i.e. moves away from the brake stator 11-18 under the elastic force of the reset spring 11-21, so as to reset and release the parking state.

[0158] In order to guide the movement of the brake pad 11-15, the brake stator 11-18 is provided with a guide pin 11-22 parallel to the output worm 11-6, and the brake pad 11-15 is provided with a guide notch 11-23 matched with the guide pin 11-22.

[0159] Specifically, the brake stator 11-18 is provided with a mounting hole II on the side facing the brake pad 11-15, and the guide pin 11-22 is mounted in the mounting hole II. When the parking is released or the brake pad 11-15 moves, the guide pin 11-22 can guide the movement of the brake pad 11-15.

[0160] At the same time, the guide pin 11-22 can also limit the brake pad 11-15 in the circumferential direction, avoiding the brake pad 11-15 from rotating with the friction plate 11-14 and the like.

[0161] In the embodiment, the parking assembly is arranged at the end of the box body 11-1 away from the motor 11-4, i.e. at the front end of the cavity of the box body 11-1. The output worm 11-6 is connected to the parking assembly at the end away from the motor 11-4, i.e. at the front end, through the brake pad 11-15 and the friction plate 11-14.

[0162] When the parking assembly is matched with the motor 11-4, the cover 11-11 can be removed to install the parking assembly, and the cover 11-11 can protect the parking assembly well.

[0163] The parking assembly is not limited to be installed at the front end of the output worm 11-6, but can also be installed at the tail of the motor 11-4 (similar to the mode in Embodiment 6), so as to be matched with the rear end of the output worm 11-6, and the parking effect can also be achieved.

[0164] The folding mode and folding process of the four-wheel ball bag vehicle disclosed in the embodiment are the same as those of the four-wheel ball bag vehicle in Embodiment 1.

[0165] Embodiment 4

[0166] As shown in FIGS. 14-15, on the basis of Embodiment 1, the embodiment further provides a foldable electric golf bag vehicle, which has the same general structure as that of Embodiment 1, and the difference is that:

[0167] The rear end of the vehicle frame 2 of the electric golf bag vehicle is provided with a battery assembly opening, and the battery 45 of the electric golf bag vehicle is assembled into the battery compartment in the vehicle frame 2 from the battery assembly opening.

[0168] In Embodiment 1, the battery 45 is assembled into the battery compartment from the top of the vehicle frame 2, and the battery 45 cannot be disassembled after the electric golf bag vehicle is folded, which is very inconvenient to use. In order to solve this problem, the embodiment provides an electric golf bag vehicle in which the battery 45 is assembled from the rear end of the vehicle frame 2.

[0169] Specifically, the position of the lower locking wrench 23 is the battery assembly opening, and after the lower locking wrench 23 is turned upward to be opened, the battery 45 in the battery compartment can be taken out or assembled into the battery compartment. Even if the electric golf bag vehicle is in a folded state, the disassembly and assembly of the battery 45 can still be realized, and the use is more convenient and simple.

[0170] In order to further reduce the size of the electric golf bag vehicle when it is folded, the rear side of the vehicle frame 2 of the electric golf bag vehicle is provided with a support wheel 26 which can be horizontally retracted into the bottom of the vehicle frame 2.

[0171] Specifically, the bottom of the vehicle frame 2 is provided with two insertion holes 28, the support wheel 26 is installed on a support wheel seat 29, the support wheel seat 29 is rotationally assembled on two parallel support wheel frames 30, and the support wheel frames 30 are correspondingly assembled in the two insertion holes 28.

[0172] The four-wheel golf bag car of the embodiment is folded in the same way as the four-wheel golf bag car of embodiment 1. The difference is only in the folding process at the support wheel 26, i.e. when folding the electric golf bag car, the support wheel seat 29 is turned downward, and the support wheel frame 30 is pushed forward, so that the support wheel 26, the support wheel seat 29 and the support wheel frame 30 are all located at the bottom of the frame 2.

[0173] When the electric golf bag car is in use, the support wheel seat 29 is turned to a position at the same height as the support wheel frame 30, so as to cooperate with the rear wheel 1 and the front wheel 3 to support the electric golf bag car.

[0174] When the battery 45 is disassembled in the unfolded state, the support wheel seat 29 needs to be turned downward first, and then the lower locking wrench 23 is turned upward to open the battery assembly opening. At this time, the battery 45 is inserted or extracted. And in this process, the support wheel frame 30 can also guide and support the insertion or extraction of the battery 45.

[0175] When the battery 45 is disassembled in the folded state, since the support wheel 26 is located at the bottom of the frame 2, the lower locking wrench 23 is turned upward to open the battery assembly opening, and the battery 45 can be disassembled.

[0176] Preferably, in order to facilitate the opening and closing of the battery 45, the lower locking wrench 23 is provided with a switch opening 31 for accommodating the switch 32 of the battery 45.

[0177] Embodiment 5

[0178] As shown in FIG. 16, based on embodiment 4, the embodiment also provides a foldable electric golf bag car, which is different in that:

[0179] The front side of the battery cabin is provided with a pop-out assembly 44 capable of pushing the battery 45 outward from the battery assembly opening.

[0180] The pop-out assembly 44 includes a pop-out cabin 44-1 provided on the front side of the battery cabin, a pop-out sleeve 44-2 with an open front end provided in the pop-out cabin 44-1, and a pop-out spring 44-3 provided in the pop-out sleeve 44-2.

[0181] The battery 45 is installed in the battery cabin in a way that the back end is higher than the front end, the back end of the battery 45 is provided with a battery locking block 45-1 extending from the top of the battery 45, the battery locking block 45-1 is provided with an upper lever 45-2 extending from the back end surface of the battery 45, the back end top of the battery cabin is provided with a battery 45 locking hole 38 matched with the battery locking block 45-1, and the bottom of the battery locking block 45-1 is provided with a locking spring (not shown in the figure).

[0182] In this embodiment, the folding and unfolding locking of the lower main pipe 6 is in the manner of embodiment 2, so there is no lower locking wrench 23 structure, and the rear end of the battery compartment, i.e. the battery assembly opening, is in an open state, and there is no lower locking wrench 23 shielding in embodiment 4.

[0183] When the battery 45 is installed in the battery compartment, the battery locking block 45-1 extends into the battery 45 locking hole 38 under the action of the bottom locking spring, and the ejection spring 44-3 is in a compressed state. When the battery 45 needs to be removed, the upper lever 45-2 on the battery locking block 45-1 is pushed down to make the battery locking block 45-1 exit from the battery 45 locking hole 38, at this time the battery 45 can be pushed backward by the ejection sleeve 44-2 under the action of the ejection spring 44-3, and the battery 45 can be extended from the battery assembly opening, and the battery 45 can be quickly and simply removed from the battery compartment.

[0184] In addition, the battery switch 32 for connecting or disconnecting the battery 45 and the electric golf bag vehicle is extended from the rear end of the battery 45, and when the battery 45 is connected to the electric golf bag vehicle, the power connection is connected to the golf bag connection at the bottom of the battery 45. If the battery 45 is to be removed, the battery switch 32 needs to be pushed up in advance to move the power connection of the battery 45 upward and separate it from the golf bag connection, and then the above-mentioned operation of removing the battery 45 can be performed. In this way, not only can the damage to the power connection be avoided, but also the removal of the battery 45 can be performed in a power-off state, which is safe.

[0185] In this embodiment, since the battery 45 is designed to be inclined with the front low and the rear high, the support wheel 26 will not interfere with the removal of the battery 45, so the support wheel seat 29 of this embodiment is directly fixed to the rear end of the support wheel frame 30, and does not need to be designed to rotate downward when the battery 45 is removed. Correspondingly, when the electric golf bag vehicle is folded, the support wheel frame 30 only needs to be moved forward and retracted into the bottom of the vehicle frame 2, and the operation is more simple.

[0186] Preferably, at least one support wheel frame 30 is provided with a positioning hole on the outer side near the front end and the rear end, and the vehicle frame 2 is provided with a positioning screw. When the support wheel 26 is extracted in place, the positioning screw can be automatically ejected into the positioning hole of the support wheel frame 30 near the front end to lock the support wheel 26, avoiding its random forward movement. Similarly, when the support wheel 26 is moved forward and retracted into the bottom of the vehicle frame 2, the positioning screw is automatically ejected into the positioning hole of the support wheel frame 30 near the rear end to lock the support wheel 26, avoiding its random backward movement.

[0187] Embodiment 6

[0188] As shown in FIGS. 17-18, on the basis of Embodiment 1, the present embodiment also provides a foldable electric golf bag vehicle, which is also a four-wheel golf bag vehicle, and two rear wheels 1 of the four-wheel golf bag vehicle are each provided with a wheel built-in power system 11.

[0189] The difference is that the wheel built-in power system 11 in the present embodiment adopts another structure.

[0190] Specifically, the wheel built-in power system 11 comprises a motor 11-4, and a speed reduction assembly in transmission connection with the motor 11-4, and the speed reduction assembly is connected with an axle 21 (in the present embodiment, the axle 21 of the rear wheel 1) of a wheel corresponding to the wheel built-in power system 11.

[0191] In the present embodiment, the motor 11-4 and the speed reduction assembly are both arranged in a box body 11-1, and the motor 11-4 is fixedly connected with the box body 11-1.

[0192] In the present embodiment, the hinged manner of the connecting rod 5 and the wheel built-in power system 11 is not limited to hinging the connecting rod 5 with the box body 11-1. In the case where the box body 11-1 is not arranged, the connecting rod 5 can be directly connected with the motor 11-4 by using a corresponding hinged structure, and the effect that the connecting rod 5 and the rear wheel 1 can follow the folding during the folding of the golf bag vehicle can also be achieved.

[0193] Specifically, the speed reduction assembly comprises a worm wheel 11-5 in meshing connection with an output worm 11-6 of the motor 11-4, and a gear set for transmitting the torque of the worm wheel 11-5 to the axle 21 of the corresponding wheel.

[0194] On the basis of Embodiment 1, the present embodiment adds a gear transmission in the wheel built-in power system 11, that is, the torque of the worm wheel 11-5 needs to pass through the gear set before being transmitted to the axle 21 of the corresponding wheel.

[0195] By arranging the gear set, the motor 11-4 can be installed in a biased manner, so that the structure of the entire wheel built-in power system 11 is more compact, and the application range of the motor type can also be increased.

[0196] In the present embodiment, the gear set comprises a main gear 11-24 and a sub gear 11-25 in meshing connection, wherein the main gear 11-24 and the worm wheel 11-5 are coaxially arranged, and the sub gear 11-25 is arranged on the axle 21 of the corresponding rear wheel 1.

[0197] During transmission, the output worm 11-6 of the motor 11-4 drives the worm wheel 11-5 to rotate, the main gear 11-24 rotates synchronously with the worm wheel 11-5, and the sub gear 11-25 rotates under the drive of the main gear 11-24, thereby driving the axle 21 and the corresponding rear wheel 1 to rotate.

[0198] The four-wheel golf bag vehicle of the present embodiment has the same folding mode and folding process as the four-wheel golf bag vehicle of Embodiment 1.

[0199] Embodiment 7

[0200] As shown in Figs. 19-20, based on Embodiment 6, the present embodiment also provides a foldable electric golf bag vehicle which has substantially the same structure as that of Embodiment 6, except that:

[0201] The wheel built-in power system 11 also comprises a parking assembly, i.e. the parking assembly is added to the wheel built-in power system 11 of Embodiment 6.

[0202] In the present embodiment, the parking assembly is located at the tail of the motor 11-4. The structure of the parking assembly, the connection mode with the output worm 11-6, and the working principle are all the same as those of the parking assembly of Embodiment 3.

[0203] The four-wheel golf bag vehicle of the present embodiment has the same folding mode and folding process as the four-wheel golf bag vehicle of Embodiment 1.

[0204] Embodiment 8

[0205] As shown in Fig. 21, based on Embodiment 6, the present embodiment also provides a foldable electric golf bag vehicle which is a three-wheel golf bag vehicle, and the wheel built-in power system 11 is installed in the front wheel 3.

[0206] The wheel built-in power system 11 of the present embodiment adopts the structure of Embodiment 6.

[0207] The wheel built-in power system 11 can be installed on either side of the front wheel 3, and the box 11-1 is connected to the front wheel frame 4 of the front wheel 3.

[0208] In the present embodiment, the front wheel frame 4 has a U-shaped structure with the opening facing downward, and the lower end of the front wheel frame 4 on the side where the wheel built-in power system 11 is located is fixedly connected to the box 11-1.

[0209] The structure of the three-wheel golf bag vehicle is similar to that of the four-wheel golf bag vehicle, except that the three-wheel golf bag vehicle has only one front wheel 3 on the front side of the frame 2.

[0210] In the present embodiment, the inside of the rear wheel 1 of the three-wheel golf bag vehicle is provided with an independent hinge seat 13 which rotates with the rear wheel 1, and the outer ends of the connecting rod 5 and the auxiliary connecting rod 12 are hingedly connected to the independent hinge seat 13, so that the connecting rod 5 and the rear wheel 1 can be folded in the same way as the four-wheel golf bag vehicle of Embodiment 1.

[0211] The wheel built-in power system 11 used in this embodiment is the one disclosed in Embodiment 6.

[0212] For a three-wheeled golf bag vehicle, the wheel built-in power system 11 can be installed in the front wheel 3, and in addition, the wheel built-in power system 11 can also be installed in the following ways:

[0213] (1) only in the rear wheel 1, i.e. single-sided rear wheel 1 installation or double-sided rear wheel 1 installation;

[0214] (2) in both the front wheel 3 and the rear wheel 1, i.e. front wheel 3 and single-sided rear wheel 1 installation, or front wheel 3 and double-sided rear wheel 1 installation.
