[0026] 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. Example

[0027] Please see Figures 1 to 5 A golf cart device with a lithium battery assembly includes a golf cart 1, a trunk 2, and club barrels 3. The trunk 2 has an internal mounting mechanism 4, which includes a mounting frame 41 fixed inside the trunk 2. A sliding frame 45 is slidably connected inside the mounting frame 41, and a moving groove 411 matching the sliding frame 45 is provided on the inner side of the mounting frame 41. Support arms 46 and rotating rods 47 are rotatably connected to both sides of the sliding frame 45, and a support plate 412 for placing the battery is rotatably connected to the other end of the support arms 46 and the rotating rod 47. A mechanism for restricting the movement of the support plate 412 is fixedly connected to the support arms 46. The limiting rod 48 and the placement frame 41 are provided with a sliding groove 49 that matches the limiting rod 48, so that the moving slide frame 45 drives the support arm 46 to slide inside the sliding groove 49. The support plate 412 is pulled out from the inside of the placement frame 41 and lifted by rotating the support arm 46 and the rotating rod 47, which facilitates the disassembly and maintenance of the battery. The end of the placement frame 41 near the sliding groove 49 is provided with a limiting hole 410 to prevent the support plate 412 from slipping. The support plate 412 is fixedly connected with a movable groove 413, and the battery assembly 6 is movably connected to the support plate 412 through the movable groove 413. The placement frame 41 is also provided with a pop-out mechanism 5.

[0028] The battery assembly 6 includes an assembly plate 61, on which multiple sets of batteries 62 are detachably connected. The assembly plate 61 is matched with the movable slot 413 so that the assembly plate 61 can slide out from the support plate 412. The side of the placement rack 41 is rotatably connected to a protective plate 42 for protection via a hinge 44. Two plugs 43 are fixedly connected to the protective plate 42. A fixing block 414 matching the plugs 43 is provided above the placement rack 41. The inside of the fixing block 414 is movably connected to a limiting tenon 415 matching the plugs 43 via an elastic component 416 so that the protective plate 42 and the placement rack 41 can be opened and fixed. The side of the sliding frame 45 is provided with an annular groove 417 matching the limiting rod 48 to limit the displacement distance of the support plate 412 into the placement rack 41.

[0029] Firstly, when the battery 62 needs to be disassembled and repaired, the operator manually pulls the support plate 412. Since the two sides of the sliding frame 45 are rotatably connected to the support arm 46 and the rotating rod 47 respectively, and the other end of the support arm 46 is rotatably connected to the support plate 412 used to place the battery, and the limiting rod 48 fixedly connected to the support arm 46 is located in the sliding groove 49 opened inside the placement frame 41, when the sliding frame 45 moves, it will drive the support arm 46 to slide synchronously in the sliding groove 49. During this process, the support arm 46 and the rotating rod 47 will rotate around their respective connection points, thereby gradually... As the support plate 412 is gradually pulled out and raised from the placement frame 41, the limiting rod 48 moves with the support arm 46 to the limiting hole 410 near the end of the slide groove 49 on the placement frame 41. The limiting hole 410 effectively prevents the support plate 412 from accidentally slipping off. At this time, maintenance personnel can easily inspect, repair, or replace the battery assembly 6 movably connected to the support plate 412 via the movable groove 413. If the battery 62 in the battery assembly 6 needs to be further disassembled, the assembly plate 61 can simply be slid off the support plate 412 along the movable groove 413. However, the installation process is performed in the reverse order of disassembly. The assembly plate 61 is slid back into the movable groove 413 and secured. Then, the support plate 412 is pushed back into the placement frame 41, restoring the support arm 46 and rotating rod 47 to their initial positions. Finally, the sliding frame 45 is reset. The two bolts 43 fixedly connected to the protective plate 42 engage with the limiting tenon 415 controlled by the elastic component 416 within the fixing block 414 above the placement frame 41, achieving a tight closure and fixation between the protective plate 42 and the placement frame 41, preventing external dust and debris from entering. Moisture and potential impacts can damage the battery assembly 6 inside the placement rack 41. When it is necessary to operate inside the placement rack 41, simply press the elastic component 416 to disengage the limiting tenon 415 from the plug 43, and the protective plate 42 can be easily opened. The annular groove 417 on the side of the sliding frame 45, which matches the limiting rod 48, can limit the excessive displacement of the support plate 412 into the placement rack 41, ensuring the stability and reliability of the entire structure during operation and preventing structural damage or interference with the normal installation and disassembly of the battery assembly 6 due to unexpected situations. Example

[0030] Please see Figures 1 to 5 This embodiment provides a technical solution based on embodiment one: the pop-out mechanism 5 includes a fixed frame 51 fixed inside the placement frame 41, an irregularly shaped airbag 52 is provided between the fixed frame 51 and the placement frame 41, a detector for early warning of battery combustion is provided inside the fixed frame 51, and the electronic controller inside the irregularly shaped airbag 52 is electrically connected to the detector, the end of the irregularly shaped airbag 52 is connected to a pop-out bladder 53, and a limiting ring 54 matching the pop-out bladder 53 is fixedly connected on the fixed frame 51, and the placement frame 41 is also provided with a wire groove 55 to facilitate wire connection;

[0031] Under normal operating conditions, the detector inside the mounting bracket 51 continuously monitors various operating parameters of the battery, such as temperature, voltage, and current, to determine whether the battery is in normal working condition. Once the detector detects an abnormal or dangerous situation such as battery combustion, it immediately sends a trigger signal to the electronic controller inside the irregularly shaped airbag 52. Upon receiving the signal, the electronic controller quickly initiates the inflation program, causing the irregularly shaped airbag 52 to inflate rapidly. As gas continues to fill, the gas inside the irregularly shaped airbag 52 further expands through the ejection bladder 53 connected to its end. A limiting ring that matches the ejection bladder 53 is fixedly connected to the mounting bracket 51. Under the guidance and restraint of 54, the ejection bladder 53 will generate an outward thrust, pushing the battery assembly 6 in the placement frame 41 to quickly eject outward, thereby quickly separating the battery assembly 6 from the placement frame 41 and surrounding components that may cause secondary accidents, effectively avoiding more serious consequences such as fire or explosion caused by battery combustion, and minimizing safety risks. Throughout the process, the wire groove 55 opened on the placement frame 41 can ensure that the wires connected to the battery assembly 6 remain smoothly connected, without tangling, pulling or other situations that affect the normal operation and signal transmission of the ejection mechanism 5, ensuring that the ejection mechanism 5 can play a timely and effective role in an emergency.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: During operation, if the battery assembly 6 needs to be disassembled and repaired, push the sliding frame 45 to slide along the moving groove 411. The sliding frame 45 drives the support arm 46 to move in the sliding groove 49. The support arm 46 and the rotating rod 47 rotate to pull the support plate 412 out from the placement frame 41 and lift it to the limit hole 410 to prevent it from slipping. At this time, the battery assembly 6 can be operated. If the battery 62 needs to be further disassembled, slide the assembly plate 61 out from the moving groove 413 of the support plate 412. The installation is the opposite. In the pop-out mechanism 5, the detector in the fixing frame 51 monitors the battery under normal conditions. If an abnormal combustion is detected, a signal is sent to the electronic controller of the irregular airbag 52. The airbag is inflated, and the gas causes the pop-out bladder 53 to expand. Under the action of the limit ring 54, the battery assembly 6 is pushed out and separated. The wire groove 55 ensures smooth wire connection. The protective plate 42 is opened and closed and fixed by the bolt 43 and the limit tenon 415 in the fixing block 414. The annular groove 417 of the sliding frame 45 restricts the displacement of the support plate 412.
