Description

Technical Field

[0001] This utility model relates to the field of golf cart design, and in particular to the rear seat structure of a quick-assembly golf cart. Background Technology

[0002] Golf carts are environmentally friendly passenger vehicles designed and developed specifically for golf courses. They are mainly used to transport equipment on golf courses and to serve players. They can also be used in resorts, villa areas, garden hotels, tourist attractions, and other similar locations.

[0003] In existing golf carts, if a rear seat needs to be installed, it is usually fixed by welding. However, there is a technical problem that the rear seat cannot be disassembled after welding, which makes it inconvenient to use. Some golf carts use bolts to lock the rear seat, but as the vehicle is driven, the bolts are prone to vibration and falling off, resulting in poor installation security. Once the bolts fall off, the entire rear seat may separate from the frame, posing a safety hazard.

[0004] Therefore, it is necessary to design a quick-installation golf cart rear seat structure to solve the technical problem of easy loosening when using bolt installation. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] A quick-release golf cart rear seat structure includes a main beam, a frame, and an assembled rear seat, wherein the frame is fixedly mounted on top of the main beam, and the assembled rear seat is detachably mounted on the rear end of the main beam. The rear end of the main beam is fixedly installed with a tail frame, and right-angle frames are fixedly installed at both ends of the bottom side of the tail frame. U-shaped frames are welded and installed on the inner side of the right-angle frames. Two square tubes are fixedly installed on the bottom side of the assembled rear seat, and the front ends of the square tubes are inserted into the U-shaped frames at both ends of the tail frame with a gap fit. The front end of the square tube is equipped with a positioning bolt, and the front end of the square tube is fixedly installed in the U-shaped frame by the positioning bolt. The bottom surface of the tail frame and the upper surface of the U-shaped frame are separated from each other vertically. A silicone gasket is tightly installed between the tail frame and the U-shaped frame. A nut is provided at the upper end of the positioning bolt, and the silicone gasket presses against the nut of the positioning bolt.

[0007] Furthermore: the upper and lower sides of the U-shaped frame are formed with first bolt holes, and the front end of the square tube is formed with a second bolt hole that passes through it. The positioning bolt is installed through the first bolt hole and the second bolt hole.

[0008] Furthermore: the length of the positioning bolt is greater than the distance between the bottom surface of the tailstock and the upper surface of the U-shaped frame, and the tailstock has through holes formed therein, through which the positioning bolt is installed in the first bolt hole and the second bolt hole.

[0009] Furthermore, a positioning plug is formed on the upper side of the silicone pad, and the positioning plug is fitted into the through hole with a clearance fit.

[0010] Furthermore: the front end of the square tube has at least two second bolt holes, the U-shaped frame has at least two first bolt holes, and the first bolt holes and second bolt holes are arranged vertically to each other. The front end of the square tube has at least two positioning bolts.

[0011] Furthermore: the bottom side of the silicone pad is formed with a recessed groove, and a metal ring is embedded and fixed in the recessed groove.

[0025] like Figure 1-5 As shown, the quick-assembly golf cart rear seat structure of this utility model includes a main beam 1, a frame 2, and an assembled rear seat 3. The frame 2 is fixedly installed on the top of the main beam 1, and the assembled rear seat 3 is detachably installed on the rear end of the main beam 1. The rear end of the main beam 1 is fixedly installed with a tail frame 4. Right angle frames 5 are fixedly installed on both the left and right ends of the bottom side of the tail frame 4. U-shaped frames 6 are welded and installed on the inner side of the right angle frames 5. Two square tubes 7 are fixedly installed on the bottom side of the assembled rear seat 3. The front ends of the square tubes 7 are inserted into the U-shaped frames 6 at both ends of the tail frame 4 with a gap fit. The front end of the square tube 7 is equipped with a positioning bolt 8. The front end of the square tube 7 is fixedly installed in the U-shaped frame 6 by the positioning bolt 8. The bottom surface of the tail frame 4 and the upper surface of the U-shaped frame 6 are separated from each other. A silicone gasket 9 is tightly installed between the tail frame 4 and the U-shaped frame 6. A nut 10 is provided at the upper end of the positioning bolt 8. The silicone gasket 9 presses against the nut 10 of the positioning bolt 8. The principle is as follows: the square tube 7 is installed inside the U-shaped frame 6 using a positioning bolt 8. The silicone gasket 9 presses down on the nut 10 at the upper end of the positioning bolt 8, ensuring that the positioning bolt 8 always penetrates the U-shaped frame 6 and the square tube 7. Even if the nut 18 that locks the positioning bolt 8 loosens and falls off, the positioning bolt 8 will not detach from the square tube 7 and the U-shaped frame 6. Therefore, when the nut 10 falls off, the assembled rear seat 3 of this utility model will shake to remind the user to check the status of the positioning bolt 8. However, the assembled rear seat 3 will always be connected to the U-shaped frame 6 and will not fall off on its own, thus avoiding safety hazards. In addition, when disassembling the assembled rear seat 3, the silicone gasket 9 needs to be manually removed to effectively remove the positioning bolt 8, achieving quick installation and disassembly and enabling the golf cart to achieve the technical effect of multi-purpose use.

[0026] Furthermore: the upper and lower sides of the U-shaped frame 6 are both formed with first bolt holes 11, and the front end of the square tube 7 is formed with a second bolt hole 12 that passes through it. The positioning bolt 8 is installed through the first bolt hole 11 and the second bolt hole 12. The positioning bolt 8 can pass through the U-shaped frame 6 and the square tube 7 through the first bolt hole 11 and the second bolt hole 12. After the silicone gasket 9 is installed, the positioning bolt 8 can always be in the state of passing through the U-shaped frame 6 and the square tube 7, ensuring that it is firmly installed and will not fall off on its own.

[0027] Furthermore, the length of the positioning bolt 8 is greater than the distance between the bottom surface of the tailstock 4 and the upper surface of the U-shaped frame 6. The tailstock 4 has a through hole 13 formed therein, and the positioning bolt 8 is installed in the first bolt hole 11 and the second bolt hole 12 through the through hole 13. This facilitates the installation and use of the positioning bolt 8. When disassembling the positioning bolt 8, the silicone gasket 9 must be removed first, and then it can be taken out through the through hole 13. This effectively prevents the positioning bolt 8 from falling off by itself. Even if the silicone gasket 9 falls off, because the positioning bolt 8 is longer than the distance between the tailstock 4 and the U-shaped frame 6, the positioning bolt 8 will still be stuck in the first bolt hole 11 and the second bolt hole 12 when it is not aligned with the through hole 13. This effectively prevents the positioning bolt 8 from falling off by itself and reduces safety hazards.

[0028] Furthermore, a positioning plug 14 is formed on the upper side of the silicone pad 9, and the positioning plug 14 is fitted into the through hole 13 with a clearance fit; this ensures the stable installation of the silicone pad 9, and after installation, it can be locked in the through hole 13, preventing the silicone pad 9 from falling off on its own.

[0029] Furthermore: at least two second bolt holes 12 are provided at the front end of the square tube 7, at least two first bolt holes 11 are provided on the U-shaped frame 6, and the first bolt holes 11 and the second bolt holes 12 are arranged vertically and vertically to each other, and at least two positioning bolts 8 are provided at the front end of the square tube 7; making the installation of the square tube 7 in the U-shaped frame 6 more stable.

[0030] Furthermore, the bottom side of the silicone gasket 9 is formed with a recessed groove 15, and a metal ring 16 is embedded and fixed in the recessed groove 15. The inner ring of the metal ring 16 is formed with an internal hexagonal groove 17. The nut 10 at the upper end of the positioning bolt 8 is fitted with the internal hexagonal groove 17 of the metal ring 16 with clearance. This allows the bottom side of the silicone gasket 9 to engage with the nut 10 of the positioning bolt 8, facilitating the installation and removal of the nut 18.

[0031] Furthermore: the lower end of the positioning bolt 8 is screwed with a nut 18, which is locked onto the lower surface of the U-shaped frame 6; the positioning bolt 8 can securely lock the square tube 7 into the U-shaped frame 6 through the nut 18, ensuring the stable assembly of the assembled rear seat 3.

[0032] Furthermore: the upper end of the right-angle frame 5 is installed on the bottom side of the tail frame 4 by screws, and the right-angle frame 5 and the tail frame 4 are welded and fixed to each other; the screws can provide the right-angle frame 5 with a pre-position before welding, ensuring the accurate assembly of the right-angle frame 5, and then the welding method is used for reinforcement to ensure the installation strength of the right-angle frame 5.

[0033] Furthermore: the assembled rear seat 3 includes a seat cushion bracket 19, a foot pad bracket 20, and a positioning armrest 21, which are fixedly installed on the square tube 7 from front to back; this can form the relevant structure of the assembled rear seat 3, which is convenient for actual use.

[0034] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
