Technical Field

[0001] This utility model relates to the technical field of golf cart batteries, specifically a battery protection structure for golf carts. Background Technology

[0002] During the use of golf carts, a protective structure needs to be installed inside, and the battery should be placed inside the protective structure to protect the battery and reduce potential hazards to the golf cart. However, the existing battery installation process requires first positioning the battery inside the protective structure using a pin or other structure, and then connecting the battery to the internal circuitry of the protective structure using wires. Obviously, there are significant inconveniences in these two steps. Therefore, we propose a battery protection structure for golf carts. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-4 This utility model provides a technical solution: a battery protection structure for golf carts, including a protective shell 1 and multiple battery bodies 11. The protective shell 1 is fixedly installed inside the golf cart body. The multiple battery bodies 11 are arranged and inserted into the inner cavity of the protective shell 1. The inner cavity of the protective shell 1 has symmetrically arranged positioning holes 13 on both sides. Positive external wiring 2 and negative external wiring 21 are fixedly installed on both sides of the outer end of the protective shell 1, respectively. The positive external wiring 2 and negative external wiring 21 are interconnected with the electrical components inside the golf cart through wires. First electrical connecting pieces 22 are fixedly installed in the positioning holes 13 on both sides. The first electrical connecting pieces 22 on both sides are electrically connected to the positive external wire 2 and the negative external wire 21 through wires. Positioning pins 131 that are inserted into the positioning holes 13 on both sides are slidably installed on the upper end of the battery body 11. Threaded rods 15 that are threaded to the positioning pins 131 on both sides are rotatably installed on the upper side of the battery body 11. Second electrical connecting pieces 23 that are inserted into the first electrical connecting pieces 22 on both sides are installed at the outer ends of the positioning pins 131 on both sides.

[0024] Working principle: When installing the battery body 11, insert the battery body 11 into the protective shell 1. When the positioning pin 131 and the positioning hole 13 are aligned, rotate the threaded rod 15 on the upper side of the battery body 11. Through the threaded engagement between the threaded rod 15 and the positioning pins 131 on both sides, the positioning pins 131 on both sides can be driven to move outward, so that the positioning pins 131 are inserted into the positioning hole 13, thus completing the positioning of the battery body 11.

[0025] Furthermore, when the positioning socket 13 moves to the point where it is fully inserted, the first electrical connecting piece 22 and the second electrical connecting piece 23 come into contact with each other, thereby electrically connecting the battery body 11 to the protective shell 1.

[0026] Example 2

[0027] The inner walls of the protective shell 1 are fixedly installed with mutually symmetrically arranged limiting rails 12, and each battery body 11 has a limiting slot 121 at both ends that can be inserted into the limiting rails 12 on both sides.

[0028] By engaging the limiting rail 12 and the limiting slot 121, the movement direction of the battery body 11 can be restricted within the protective shell 1, ensuring that the positioning pin 131 is aligned with the positioning hole 13.

[0029] Example 3

[0030] The lower end faces of the positioning pins 131 on both sides are respectively fixedly installed with limiting sliders 132 that fit against the upper end face of the battery body 11. The end faces of the two limiting sliders 132 are respectively fixedly installed with third electrical connecting pieces 25 that are electrically connected to the second electrical connecting piece 23 through wires. The upper end face of the battery body 11 is fixedly installed with mutually symmetrically arranged limiting rotating seats 14. The threaded rod 15 is rotatably installed between the two limiting rotating seats 14. The outer end faces of the two limiting rotating seats 14 are respectively fixedly installed with fourth electrical connecting pieces 24 that are electrically connected to the battery body 11 through wires. The four fourth electrical connecting pieces 24 on both sides are respectively electrically connected to the three third electrical connecting pieces 25 on both sides through wires.

[0031] The limit rotating seat 14 can restrict the movement direction of the threaded rod 15. The limit slider 132, through its contact with the battery body 11, can restrict the movement direction of the positioning pin 131 at the upper end of the battery body 11. Thus, the rotating threaded rod 15 can drive the positioning pins 131 on both sides to move towards or away from each other through the threaded engagement between the threaded rod and the positioning pins 131 on both sides.

[0032] By providing a third electrical connecting piece 25 and a fourth electrical connecting piece 24, the battery body 11 can be electrically connected to the second electrical connecting pieces 23 on both sides.

[0033] Example 4

[0034] The inner end face of the two side limit rotating seats 14 is provided with positioning tooth grooves 31, and the outer sides of the threaded rod 15 are provided with positioning tooth sleeves 3. The two side positioning tooth sleeves 3 are respectively inserted into the two side positioning tooth grooves 31. The threaded rod 15 is provided with a limit sliding cavity 32 in the middle. The inner end face of the two side positioning tooth sleeves 3 is fixedly installed with movable plates 33 that are inserted into the limit sliding cavity 32, and the limit sliding cavity 32 is provided with springs 34 at both ends that are fixedly connected to the two side movable plates 33 respectively.

[0035] When it is necessary to adjust the position of the positioning pin 131, the positioning tooth sleeves 3 on both sides can be pressed towards the center from the periphery of the threaded rod 15 by the movable plate 33, so that the positioning tooth sleeves 3 and the positioning tooth groove 31 are separated from each other, thereby releasing the positioning effect of the threaded rod 15 between the two limit rotating seats 14, so that the threaded rod 15 can be rotated.

[0036] After the positioning pin 131 is adjusted, the movable plate 33 is released. Under the action of the spring 34 restoring its deformation, the positioning tooth sleeves 3 on both sides can be driven to reset outward, so that the positioning tooth sleeves 3 and the positioning tooth grooves 31 can be inserted into each other. The threaded rod 15 can be positioned between the two limit rotating seats 14, thereby positioning the positioning pin 131 to prevent it from loosening and ensuring the connection effect between the positioning pin 131 and the positioning hole 13 and between the second electrical connecting piece 23 and the first electrical connecting piece 22.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
