Description

Technical Field

[0001] The present invention relates to the technical field of golf carts, and more particularly to an adjustable roof fixing device for a golf cart. Background Art

[0002] A golf cart is an important means of transportation on a golf course. It is mainly used to help players carry club bags and other equipment on the course, thereby improving playing efficiency and reducing physical exertion. It is labor-saving and fast, suitable for long-distance movement and heavy object carrying. Some high-end models are also equipped with additional facilities such as massage seats to provide a more comfortable riding experience.

[0003] The Chinese patent with the publication number CN118304627A discloses an electric golf cart, including a linkage shaft, a motor, a frame, an output shaft and a transmission structure. The transmission structure and the motor are installed on the frame. The motor drives the transmission structure to rotate. The transmission structure and the output shaft are linked so that the motor can drive the output shaft to rotate. The linkage shaft includes a straight section and a universal bending section so that the linkage shaft can output torque in different circumferential directions. The output shaft can be directly or indirectly connected to the straight section of the linkage shaft in a detachable manner to achieve transmission. The universal bending section is directly or indirectly connected to other electric golf carts in a detachable manner to achieve transmission. The linkage shaft is used to achieve transmission between two electric golf carts, so that driving any one of the carts can drive the other cart to move at the same time, which can ensure that the front car and the rear car maintain a certain distance. It is safer than traditional rope dragging. The use of the linkage shaft can have a strong off-road performance and has a great advantage on uneven roads such as ups and downs, and is suitable for driving on golf courses.

[0028] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are only examples. The adjustable roof fixing device of a golf cart involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] Reference Figure 1 and Fig.10 The present invention provides an adjustable roof fixing device for a golf cart, comprising a body 1, a base 2 is fixedly connected to the top of the body 1, two sets of slide rail mechanisms 3 are arranged at the upper edge of the base 2, a luggage box 4 is slidably arranged between the two sets of slide rail mechanisms 3, a driving mechanism 6 is arranged on the base 2, a box cover 401 is arranged on the upper side of the luggage box 4, a plurality of slots 403 are fixedly connected to the inner wall of the luggage box 4, a plurality of partitions 404 are detachably connected in the slots 403, and a linkage support mechanism 5 is arranged between the luggage box 4 and the two sets of slide rail mechanisms 3; Each set of slide rail mechanisms 3 includes a slide rail body 301, a first slide groove 302, a second slide groove 303, a first slider 304, a reinforcement 305, an arcuate slide groove 306 and a second slider 307. The slide rail body 301 is fixedly connected to the top of the base 2. The first slide groove 302 and the second slide groove 303 are both opened on the side of the slide rail mechanism 3 close to the luggage box 4. The first slider 304 is slidably connected in the first slide groove 302. The reinforcement 305 is fixedly connected to the side of the first slider 304 close to the driving mechanism 6. One end of the slider 307 is slidably connected to the second slide groove 303, the top of the car body 1 is fixedly connected to the base 2, two sets of slide rail mechanisms 3 are arranged at the upper edge of the base 2, a luggage box 4 is slidably arranged between the two sets of slide rail mechanisms 3, a driving mechanism 6 is arranged on the base 2, a box cover 401 is arranged on the upper side of the luggage box 4, a plurality of slots 403 are fixedly connected to the inner wall of the luggage box 4, a plurality of partitions 404 are detachably connected to the slots 403, and a linkage support mechanism 5 is arranged between the luggage box 4 and the two sets of slide rail mechanisms 3.

[0030] In this embodiment, it is necessary to specifically explain that: the base 2 is fixed to the top of the vehicle body 1 by bolts, and is mainly used to support the luggage box 4. The base 2 and the slide rail mechanism 3 are both made of aluminum alloy. Aluminum alloy is lighter than other metals such as manganese steel, which makes the load on the vehicle body of the aluminum alloy roof luggage rack relatively small after the luggage is loaded, which helps to improve the economy and driving stability of the vehicle. It has high strength and durability and can withstand a large weight and impact. The luggage box 4 is made of PC+ASA material. The PC+ASA mixed material has higher strength and aging resistance, and better flexibility. In the initial state, the luggage box 4 is located on the upper side of the base 2. When it is necessary to take out or place items, the luggage box 4 can be controlled to move along the first slide groove 302 and rotate a certain angle along the arc-shaped slide groove 306 to move the luggage box 4 to one side of the vehicle body 1, and the luggage box 4 can be opened to store items. The main difference between this embodiment and the prior art is that in this embodiment, the driving mechanism 6 and the slide rail mechanism 3 are used to automatically control the movement of the luggage box 4. Specifically, the output end of the servo motor 601 drives the first gear 602 to rotate. Under the meshing action of the first gear 602 and the second gear 605, the second gear 605 drives the ball screw 604 to rotate, and the ball screw 604 drives the screw sleeve 608 to move, and then the linkage sleeve 607 and the reinforcement rod 606 follow the screw sleeve 608 to move, thereby driving the two reinforcement members 305 moves synchronously, at this time, the linkage shaft 501 and the damping sleeve 502 move with the reinforcement rod 606, and under the limiting effect of the slide rail body 301, the luggage box 4 is driven to move linearly, and the second slider 307 moves with the luggage box 4. When the first slider 304 moves to the maximum distance, the second slider 307 enters the arc-shaped slide groove 306, and the arc-shaped slide groove 306 and the linkage shaft 501 are concentric structures. At this time, the luggage box 4 can rotate with the linkage shaft 501 as the center of the circle to adjust the luggage box 4 to flip to one side of the vehicle body 1, such as Figure 3 As shown, at this time, the luggage box 4 is opened and items can be stored. After the items are stored, the luggage box 4 is controlled to return to a horizontal state, and the servo motor 601 can be driven to rotate in the opposite direction to control the luggage box 4 to return to its original position. In this solution, there is no need to stand on the vehicle when storing and retrieving items. The luggage box 4 can be controlled to flip to one side of the vehicle body 1, which greatly reduces the difficulty of storing items. In addition, the servo motor 601 is connected to the vehicle power supply of the vehicle body 1, and the driver can control the position of the luggage box 4 in the driving position, especially when storing some heavy items, which makes it easier to store and retrieve items, avoids certain safety hazards, and reduces the possibility of items falling when stored. Preferably, a plurality of partitions 404 are provided in the suitcase 4. The partitions 404 are inserted into the slots 403 to change the spatial layout inside the suitcase 4. The spatial layout can be flexibly adjusted according to the needs, and the internal space can be used more efficiently to ensure that all necessities can be put in in an orderly manner, thereby avoiding hasty sorting before departure or after arrival at the destination, thereby saving time. Reasonable layout can reduce the shaking of items during transportation and avoid damage caused by collision between items, especially for fragile or sensitive items, which can greatly reduce the risk of damage; The above structure is the main structure of this embodiment, which solves the problem of difficulty in fixing roof luggage, and the movement and flipping of the luggage box 4 is an existing structure. The specific structure and connection method of the second slider 307 are not described in detail in this embodiment. In addition, the servo motor 601 controlling the rotation of the servo motor 601 also belongs to the existing technology. Therefore, this application does not make detailed limitations.

[0033] Reference Figure 4-6The driving mechanism 6 includes a servo motor 601, a first gear 602, a mounting plate 603, a ball screw 604, a second gear 605 and a follower assembly. The servo motor 601 is fixedly connected to the top of the base 2. The first gear 602 is fixedly connected to the output end of the servo motor 601. Two mounting plates 603 are provided, which are respectively embedded and fixed to the inner wall of the base 2. The ball screw 604 is rotatably connected between the two mounting plates 603. The second gear 605 is fixedly connected to the ball screw 604. The second gear 605 is meshed with the first gear 602 on the circumferential surface; the follower assembly includes a reinforcement rod 606, a linkage sleeve 607 and a screw sleeve 608, the screw sleeve 608 is threadedly connected to the circumferential surface of the ball screw 604, the reinforcement rod 606 is fixedly connected between the two reinforcement members 305, one end of the linkage sleeve 607 is fixedly connected to the circumferential surface of the reinforcement rod 606, and the other end of the linkage sleeve 607 is fixedly connected to the screw sleeve 608, and a group of limit assemblies 7 are arranged on both sides of the screw sleeve 608.

[0034] In this embodiment, it is necessary to specifically explain that: the servo motor 601 is powered by the on-board power supply of the vehicle body 1, the mounting plate 603 is embedded in the inner wall of the base 2, and is used to support the rotation of the ball screw 604, the second gear 605 and the ball screw 604 are an integral structure, the screw sleeve 608 and the linkage sleeve 607 are an integral structure, and the first gear 602 is driven to rotate by the output end of the servo motor 601 during operation, and under the meshing action of the first gear 602 and the second gear 605, the second gear 605 drives the ball screw 604 to rotate, the ball screw 604 drives the screw sleeve 608 and the linkage sleeve 607 to move, and the reinforcement rod 606 moves with the screw sleeve 608, thereby driving the two reinforcement members 305 to move synchronously, and at this time, the linkage shaft 501 and the damping shaft sleeve 502 move with the reinforcement rod 606, and under the limiting action of the slide rail body 301, the luggage box 4 is driven to move linearly on the base 2 to adjust the position of the luggage box 4.

[0035] Reference Figure 5 Each set of limiting components 7 includes a straight rod 701 and a sliding sleeve 702. The straight rod 701 is fixedly connected between the two mounting plates 603. One end of the sliding sleeve 702 is slidably connected to the circumferential surface of the straight rod 701, and the other end of the sliding sleeve 702 is fixedly connected to the screw sleeve 608.

[0036] In this embodiment, it is necessary to specifically explain that: between the two straight rods 701 of the ball screw 604, the sliding sleeve 702 is fixed on both sides of the screw sleeve 608. When the screw sleeve 608 moves, the sliding sleeve 702 moves with the screw sleeve 608. Under the limiting action of the straight rod 701, the sliding sleeve 702 and the screw sleeve 608 are ensured to move in a straight line, limiting the moving range of the screw sleeve 608, avoiding damage or accidents caused by mechanical overtravel and skewness, and extending the service life.

[0038] In this embodiment, it is necessary to specifically explain that: the lock buckle 407 is used to close and lock the suitcase lid 401, the compression belt 405 can compress the items to prevent the items from accidentally falling during transportation or storage, the partition 404 can be inserted into the slot 403 from top to bottom, and the partition 404 can be inserted into the slot 403 at different positions according to needs, thereby changing the internal space layout of the vehicle body 1, and maximizing the use of the capacity of the suitcase and reducing space waste. The partition 404 limits the movement range of the items, which can reduce the shaking of the luggage during transportation, avoid damage caused by collision between items, and greatly reduce the risk of damage.

[0039] Reference Figure 7 The arc-shaped slide groove 306 is connected to the second slide groove 303 , and the second slider 307 can slide from the second slide groove 303 into the arc-shaped slide groove 306 .

[0040] In this embodiment, it should be specifically explained that: the arc range of the arc groove 306 is within 90 degrees, and the arc groove 306 is at the same height as the center of the linkage shaft 501. The linkage shaft 501 can be moved to a position concentric with the arc groove 306. At this time, the suitcase 4 can rotate with the linkage shaft 501 as the center.

[0041] Reference Figure 4 A sunshade 8 is fixedly connected to one side of the base 2 close to the driving mechanism 6 , and an arc surface 201 is provided on the other side of the base 2 .

The curved surface 201 is a smooth transition, which can adapt to the rotation of the suitcase 4, ensuring that the rotation of the suitcase 4 will not be blocked, and the structure is more stable.

[0043] Working principle of the present invention: The main problem solved by this embodiment is: the movement of the luggage box 4 is limited by the slide rail mechanism 3, and the driving mechanism 6 drives the luggage box 4 to move to the side of the vehicle body 1, so that the overall position of the luggage box 4 can be flexibly adjusted, which solves the problem of the high position of fixed items on the roof. There is no need to stand on the vehicle to store items, which makes it easier to store large items, reduces safety hazards, and makes storage and retrieval more convenient. In addition, the partition 404 can be inserted into the slot 403 to change the internal space layout of the luggage box 4. It can be flexibly adjusted according to needs, and the internal space can be used more efficiently, thereby saving time. Reasonable layout can reduce the shaking of items during transportation and avoid damage caused by collision between items. In particular, for fragile or sensitive items, the risk of damage can be greatly reduced.

[0044] The specific steps are as follows: Step 1: Adjusting the position: Control the output end of the servo motor 601 to drive the first gear 602 to rotate. Under the meshing action of the first gear 602 and the second gear 605, the second gear 605 drives the ball screw 604 to rotate, and the ball screw 604 drives the screw sleeve 608 to move, and then the linkage sleeve 607 and the reinforcement rod 606 follow the screw sleeve 608 to move, thereby driving the two reinforcement members 305 to move synchronously. At this time, the linkage shaft 501 and the damping shaft sleeve 502 follow the reinforcement rod 606 to move. Under the limiting action of the slide rail body 301, the luggage box 4 is driven to move linearly, and the second slider 307 follows the luggage box 4 to move. When the first slider 304 moves to the maximum distance, the second slider 307 enters the arc-shaped slide groove 306. The arc-shaped slide groove 306 and the linkage shaft 501 are concentric structures. At this time, the luggage box 4 can rotate with the linkage shaft 501 as the center of the circle to adjust the luggage box 4 to flip to one side of the vehicle body 1; Step 2: storing and retrieving items: At this time, the luggage box 4 is opened through the lock buckle 407, the items are stored in the luggage box 4, and then the box cover 401 is closed and locked; Step 3: Reset: Control the suitcase 4 to return to the horizontal state, and then control the output end of the servo motor 601 to drive the first gear 602 to rotate in the opposite direction. From step 1, it can be seen that the ball screw 604 rotates in the opposite direction to make the screw sleeve 608 move in the opposite direction, and then the linkage sleeve 607, the screw sleeve 608, the reinforcement 305, and the linkage shaft 501 move in the opposite direction. Finally, the suitcase 4 moves to the original position in the direction of the servo motor 601 to achieve automatic reset.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
