Description

Technical Field

[0001] This utility model relates to the field of power supply device technology, and more specifically, to a vehicle-mounted power supply device. Background Technology

[0002] Flatbed trucks are frequently used to transport building materials during construction in mountainous areas. Since these trucks may carry equipment that requires electricity, such as lighting fixtures, surveillance cameras, and communication devices, batteries are installed at the bottom of the trucks to provide power for normal operation. In specific situations, the power supply device at the bottom of the flatbed truck can be used as a temporary power station. For example, during field operations, temporary activities, or emergencies, the flatbed truck can provide power to other equipment or tools to meet temporary power needs.

[0003] However, existing vehicle-mounted power supply devices are usually installed under the vehicle to avoid collision damage when the flatbed truck is transporting building materials. However, due to the special nature of the usage scenario, if the power supply device is exposed when the flatbed truck is transporting in mountainous areas, dust and dirt will adhere to the power supply device, making it look dirty. In severe cases, dirt may even enter the power supply device through the charging and discharging interface, rendering it unusable. Therefore, in order to address the above technical problems, a vehicle-mounted power supply device is proposed here. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle-mounted power supply device that can better protect the power supply device installed under the flatbed truck, prevent it from getting dirty, ensure its safety and service life, and make it easy to open and use when charging and discharging, only exposing the charging and discharging interface and not exposing the rest of the parts. In addition, the charging cable connected to the interface can be firmly clamped by the spring, reducing the occurrence of falling off.

[0005] This utility model is achieved through the following technical solution:

[0006] A vehicle-mounted power supply device includes a flatbed truck. A battery is fixedly connected to the bottom of the flatbed truck.

The pull rope passes through the bottom of the flatbed truck and is fixedly connected to the first baffle and the second baffle respectively. A fixing plate is fixedly connected to the bottom of the flatbed truck. A telescopic rod and a spring are fixedly connected to one side of the fixing plate, and the spring is sleeved on the outside of the telescopic rod. The telescopic rod and the spring are fixedly connected to the first baffle and the second baffle respectively.

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.

[0026] Please see Figure 1-8This utility model proposes a vehicle-mounted power supply device, including a flatbed 1. A battery 2 is fixedly connected to the bottom of the flatbed 1. A first baffle 4 and a second baffle 5 are slidably connected to the bottom of the flatbed 1, and the second baffle 5 is slidably connected to the first baffle 4. The battery 2 is located in the internal space between the first baffle 4 and the second baffle 5. An arc-shaped groove 6 is opened on the outside of the first baffle 4 and the second baffle 5. A cavity 9 is opened inside the flatbed 1. A rotating column 10 is rotatably connected inside the cavity 9. A pull rope 12 is fixedly connected to the outside of the rotating column 10. The pull rope 12 passes through the bottom of the flatbed 1 and is fixedly connected to the first baffle 4 and the second baffle 5 respectively. A fixing plate 14 is fixedly connected to the bottom of the flatbed 1. A telescopic rod 15 and a spring 16 are fixedly connected to one side of the fixing plate 14. The spring 16 is sleeved on the outside of the telescopic rod 15. The telescopic rod 15 and the spring 16 are fixedly connected to the first baffle 4 and the second baffle 5 respectively.

[0027] An interface 3 is provided on one side of the battery 2, and the position of the interface 3 is adapted to the position of the arc-shaped groove 6. The charging cable connected to the interface 3 can be firmly clamped through the arc-shaped groove 6.

[0028] The size of the second baffle 5 is slightly larger than that of the first baffle 4, and the first baffle 4 can be slidably connected to the inside of the second baffle 5. The first baffle 4 and the second baffle 5 can cooperate with each other to completely protect the battery in the internal space.

[0029] The bottom of the flatbed 1 is provided with a sliding groove 7. The upper sides of the first baffle 4 and the second baffle 5 are fixedly connected with sliders 8, and the sliders 8 are slidably connected to the sliding groove 7. The first baffle 4 and the second baffle 5 are slidably connected to the flatbed 1 through the sliding groove 7 and the sliders 8.

[0030] The flatbed 1 has a screw 11 on its external rotating connection, and the screw 11 is fixedly connected to the rotating column 10. The bottom of the flatbed 1 is fixedly connected to a guide 13, and the pull rope 12 is fixedly connected to the first baffle 4 and the second baffle 5 respectively through the guide 13 and the fixing plate 14. The guide 13 has the function of guiding the pull rope 12.

[0031] The bottom of the flatbed trolley 1 is fixedly connected to a pulley 17, and the outside of the flatbed trolley 1 is fixedly connected to a connector 18. By pulling the connector 18 and the pulley 17, the flatbed trolley 1 can be moved to transport building materials.

[0032] The working principle of a vehicle-mounted power supply device based on an embodiment is as follows: by setting a first baffle 4 and a second baffle 5, which are of different sizes and can slide and connect with each other, the battery 2 can be fully wrapped, thus providing good protection for the battery 2 installed under the flatbed truck 1, preventing mud contamination, and ensuring its safety and service life. When the battery 2 needs to be charged or discharged, the screw 11 is rotated, which causes the rotating column 10 to rotate, driving the pull rope 12 to pull the first baffle 4 and the second baffle 5 and separate them, and compressing the spring 16, so that the arc-shaped groove 6 can be connected to form a circular groove, only exposing the charging and discharging interface 3, and preventing it from being completely exposed. With the remaining parts exposed, connect the charging cable to interface 3, then loosen the screw 11. Under the action of spring 16, the arc-shaped groove 6 will tightly clamp the charging cable, covering the excess exposed parts of the battery 2. This prevents other parts of the battery 2 from being exposed and getting dirty during use, and also prevents the charging cable from falling off. At the end of use, turn the screw 11 again to separate the first baffle 4 and the second baffle 5. At this time, the corresponding plug wires can be unplugged. Then loosen the screw 11 again. The spring 16 will provide a pushing force to reset the first baffle 4 and the second baffle 5, completing the overall closure of the battery 2 for protection.
