Description

Technical Field

[0001] This utility model relates to the field of motor technology for golf carts, specifically a motor for golf carts that is easy to maintain. Background Technology

[0002] A golf cart is a lightweight, electric or fuel-powered vehicle designed specifically for golf courses, primarily used to transport players and golf equipment.

[0003] The drive motor of an electric golf cart typically consists of a motor body and an end cap, which are bolted together. After prolonged use, the motor may require maintenance due to issues such as carbon brush wear and bearing aging, necessitating the removal of the end cap. Maintenance requires complete removal of the bolts to separate the end cap from the motor body. Reinstallation necessitates precise alignment of the mounting holes, requiring operators to repeatedly adjust the position and manually stabilize the end cap. Even slight misalignment can lead to displacement, necessitating realignment and extending maintenance time. During installation, the end cap lacks any auxiliary positioning structure and relies solely on manual support. If the operator releases their grip or experiences external interference (such as tool impact), the end cap can easily shift or even fall, damaging internal components. Utility Model Content

[0004] The purpose of this invention is to provide a convenient-to-maintain motor for golf carts, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor for golf carts that is easy to maintain, comprising a motor body and an end cover, wherein the surfaces of the motor body and the end cover are provided with pre-connection components and movable components;

[0006] The pre-connected component includes:

[0007] Ring 1 is used to mate with Ring 2.

[0008] The socket is used to connect to the fixing post;

[0009] The slot is used to engage with the card plate to stabilize the motor body and the end cover;

[0010] Transmission components are used to drive the synchronous movement of various mechanisms.

[0011] Preferably, the first ring is fixed to the surface of the motor body, and the second ring is fixed to the surface of the end cover. The surface of the first ring has an insertion hole, and the inner side of the insertion hole has a slot. A fixing post is fixed to the side of the second ring near the first ring. The fixing post has a cavity inside, and a circular plate is rotatably connected to the inner wall of the cavity. A connecting hole is formed on the surface of the circular plate, and a circular rod abuts against the inner wall of the connecting hole. A clamping plate is fixed to the end of the circular rod away from the circular plate, and the end of the clamping plate away from the circular rod passes through the fixing post, with the clamping plate slidably connected to the fixing post. The pre-connection assembly includes a transmission component. The fixing post is installed into the insertion hole. Through the transmission component, the circular rod, the connecting hole, and the circular plate, the clamping plate enters the slot, thus limiting the mutual positioning of the first and second rings, and simultaneously limiting the positioning of the motor body and the end cover. At this point, it can be normally fixed with bolts without requiring prolonged manual handling, and there is no risk of accidental misalignment. This facilitates installation after maintenance and improves installation efficiency.

[0012] Preferably, the transmission component includes a rotating rod, which is fixed to the side of the circular plate away from the clamping plate. The end of the rotating rod away from the circular plate passes through a fixed post and a second ring, and the rotating rod is rotatably connected to the fixed post and the second ring. A first gear passes through and is fixed to the end of the rotating rod away from the circular plate. A second gear is rotatably connected to the side of the second ring away from the fixed post. A fixed ring is fixed to the side of the second ring away from the fixed post. The first gear meshes with the second gear. A spiral spring is fixed to the inner side of the fixed ring. The end of the spiral spring away from the fixed ring is fixed to the outer surface of the second gear. When the circular plate rotates, it drives the rotating rod, the first gear, and the second gear to rotate synchronously.

[0013] Preferably, the movable component includes a fixed rod, which is fixed to the surface of the second gear. The fixed rod passes through and is slidably connected to a sliding plate. A spring is fixed to the side of the sliding plate away from the second gear. The end of the spring away from the sliding plate is fixed to the surface of the fixed rod away from the second gear. An insert rod is fixed to the side of the sliding plate near the second ring. A slot is provided on the side of the second ring away from the fixed post. The insert rod is inserted into the slot to limit the movement of the second gear and prevent accidental contact that could affect stability.

[0014] Preferably, the connecting hole is arc-shaped, which can drive the round rod and the clamping plate to move radially synchronously when the round plate rotates, making it easy to separate the clamping plate from the clamping slot.

[0015] Preferably, the end of the card plate away from the round rod is set as an inclined surface, which can drive the card plate into the cavity when it is pressed, without affecting the docking.

[0016] Compared with the prior art, this utility model provides a convenient-to-maintain motor for golf carts, which has the following advantages:

[0017] 1. This golf cart uses a maintenance-friendly motor. Through pre-connected components, during installation, the fixing post is inserted into the socket. The inner wall of the socket abuts against the inclined surface of the locking plate. The round rod, connecting hole, and round plate drive the rotating rod, gear one, and gear two to rotate. A spiral spring causes the locking plate to enter the slot, thus mutually limiting the movement of ring one and ring two, simultaneously limiting the motor body and end cover. At this point, it can be normally fixed with bolts without prolonged manual operation, preventing accidental misalignment and facilitating installation after maintenance, improving installation efficiency.

[0018] 2. This golf cart uses a motor that is easy to maintain. Through the set movable components, when the first ring and the second ring are mutually limited, the insert rod enters the slot, which can limit the second gear. This avoids accidentally touching the second gear during installation, which would affect the limiting stability between the motor body and the end cover. Attached Figure Description

[0025] like Figures 1-5As shown, this utility model provides a technical solution: a motor for golf carts that is easy to maintain, including a motor body 1 and an end cover 2. The surfaces of the motor body 1 and the end cover 2 are provided with a pre-connection assembly 3 and a movable assembly 4. The pre-connection assembly 3 includes: a first ring 30, a second ring 31, an insertion hole 32, a slot 33, a fixing post 34, a cavity 35, a circular plate 36, a connecting hole 37, a circular rod 38, a clamping plate 300, a transmission component 39, a rotating rod 390, a first gear 391, a fixing ring 392, a spiral spring 393, and a second gear 394.

[0026] Ring 1 30 is fixed to the surface of motor body 1, and ring 2 31 is fixed to the surface of end cover 2. Ring 1 30 has an insertion hole 32 on its surface, and a slot 33 is formed on the inner side of the insertion hole 32. A fixing post 34 is fixed to the side of ring 2 31 near ring 1 30. A cavity 35 is formed inside the fixing post 34. A circular plate 36 is rotatably connected to the inner wall of the cavity 35. A connecting hole 37 is formed on the surface of the circular plate 36. A circular rod 38 abuts against the inner wall of the connecting hole 37. A clamping plate 300 is fixed to the end of the circular rod 38 away from the circular plate 36. One end of rod 38 passes through fixed post 34, and clamping plate 300 is slidably connected to fixed post 34. Pre-connection assembly 3 includes transmission component 39, which includes rotating rod 390. Rotating rod 390 is fixed to the side of circular plate 36 away from clamping plate 300. The end of rotating rod 390 away from circular plate 36 passes through fixed post 34 and ring 2 31, and rotating rod 390 is rotatably connected to fixed post 34 and ring 2 31. Gear 1 391 passes through and is fixed to the end of rotating rod 390 away from circular plate 36. Gear 2 is rotatably connected to the side of ring 2 31 away from fixed post 34. A retaining ring 392 is fixed to the side of the second ring 31 away from the retaining post 34. Gear 1 391 meshes with gear 2 394. A spiral spring 393 is fixed to the inner side of the retaining ring 392. The end of the spiral spring 393 away from the retaining ring 392 is fixed to the outer surface of gear 2 394. The connecting hole 37 is arc-shaped. The end of the clamping plate 300 away from the round rod 38 is set as an inclined surface. The retaining post 34 is installed into the insertion hole 32. The inner wall of the insertion hole 32 abuts against the inclined surface of the clamping plate 300. The clamping plate 300 moves into the cavity 35 and passes through the round rod 38. 8. The connecting hole 37 and the circular plate 36 drive the rotating rod 390, gear one 391, and gear two 394 to rotate, causing the spiral spring 393 to retract. When the position of the clamping plate 300 is parallel to the clamping groove 33, the spiral spring 393 releases. At this time, gear two 394, gear one 391, rotating rod 390, and circular plate 36 reverse. Through the connecting hole 37, the circular rod 38 drives the clamping plate 300 to reset, allowing the clamping plate 300 to enter the clamping groove 33. This allows the circular ring one 30 and circular ring two 31 to mutually limit each other, thus synchronously limiting the motor body 1 and the end cover 2. At this point, it can be normally fixed with bolts without the need for personnel to hold it for a long time, and it will not cause accidental contact that could lead to displacement. This facilitates installation after maintenance and improves installation efficiency.

[0027] The active component 4 includes a fixing rod 40, which is fixed to the surface of the second gear 394. The fixing rod 40 passes through and is slidably connected to a sliding plate 41. A spring 42 is fixed to the side of the sliding plate 41 away from the second gear 394. The end of the spring 42 away from the sliding plate 41 is fixed to the surface of the end of the fixing rod 40 away from the second gear 394. An insert rod 43 is fixed to the side of the sliding plate 41 near the second ring 31. A slot 44 is opened on the side of the second ring 31 away from the fixing post 34. The insert rod 43 enters the slot 44 to limit the second gear 394, so as to avoid accidentally touching the second gear 394 during installation and affecting the limiting stability between the motor body 1 and the end cover 2.

[0028] When it is necessary to install the motor body 1 and the end cover 2, the first ring 30 and the second ring 31 are fitted together, and the sliding plate 41 is pulled to disengage the insertion rod 43 from the slot 44. At this time, the fixing post 34 is installed into the insertion hole 32. The inner wall of the insertion hole 32 abuts against the inclined surface of the clamping plate 300. The clamping plate 300 moves into the cavity 35, which drives the round rod 38 to move. The surface of the round rod 38 abuts against the inner wall of the connecting hole 37, which drives the round plate 36 to rotate clockwise. At the same time, the round plate 36 drives the rotating rod 39. 0. Gear 1 391 and Gear 2 394 rotate, and the spiral spring 393 winds up. When the position of the clamping plate 300 is parallel to the clamping groove 33, the spiral spring 393 is released. At this time, Gear 2 394, Gear 1 391, rotating rod 390 and circular plate 36 reverse. Through the connecting hole 37, the circular rod 38 drives the clamping plate 300 to reset, so that the clamping plate 300 enters the clamping groove 33. This allows the circular ring 1 30 and circular ring 2 31 to limit each other, and simultaneously limit the motor body 1 and the end cover 2. Simultaneously, the slide plate 41 is released, and the spring 42 drives the slide plate 41 and the insert rod 43 into the slot 44, which limits the gear 2 394. This prevents accidental contact with the gear 2 394 during installation, which would affect the stability of the limit between the motor body 1 and the end cover 2. At this time, it can be fixed normally by bolts without the need for personnel to hold it for a long time, and there will be no accidental contact that could cause displacement. This facilitates installation after maintenance and improves installation efficiency. When maintenance is required, the bolts are removed, and the slide plate 41 is pulled again to disengage the insert rod 43 from the slot 44. This allows the fixing rod 40 to be pulled to rotate the gear 2 394, which in turn drives the gear 1 391, the rotating rod 390, and the circular plate 36 to rotate synchronously. This, in turn, drives the circular rod 38 and the clamping plate 300 to move radially synchronously through the connecting hole 37, which in turn drives the clamping plate 300 to disengage from the clamping slot 33 and release the limit. At this time, the end cover 2 and the motor body 1 can be separated normally, and maintenance can be performed inside the motor body 1.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
