[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing trolley case battery pack, comprising a shell, a support plate fixedly connected to the inner wall of the shell, a shock-absorbing mechanism provided at the bottom of the support plate, a battery module provided at the top of the support plate, an inverter fixedly connected to the middle of the top of the battery module, handles fixedly connected to both sides of the top of the battery module, an adjustment mechanism provided on the left side surface of the shell, a cover hinged to the top of the shell, and limiting members provided at the four corners of the battery module, the limiting members being fixedly connected to the bottom of the shell; The shock absorption mechanism includes a sliding rod, which is slidably connected to both sides of the bottom of the housing. A universal wheel is fixedly connected to the bottom of the sliding rod. A spring is sleeved on the surface of the sliding rod. A fixing ring is provided at the bottom of the spring. The fixing ring is fixedly connected to the surface of the sliding rod. A connecting rod is fixedly connected between the two sliding rods.
[0006] Preferably, a mounting bracket is slidably connected to the surface of the sliding rod, and the mounting bracket is fixedly connected to the bottom of the housing. The sliding rod can slide inside the mounting bracket, providing a vertical movement track for the sliding rod.
[0007] Preferably, a mounting plate is fixedly connected to the surface of the sliding rod, a groove is formed in the mounting plate, a vertical plate is slidably connected in the groove, a fixing member is fixedly connected to the bottom of the vertical plate, and the fixing member is fixedly connected to the bottom of the housing. The cooperation of the mounting plate, the groove and the vertical plate further restricts the movement trajectory of the sliding rod, prevents it from tilting or twisting during vertical movement, and disperses the pressure on the sliding rod, thus extending the service life of the shock absorption mechanism.
[0008] Preferably, a fixing frame is fixedly connected to the top of the vertical plate, and the fixing frame is fixedly connected to the inner wall of the shell. A connecting plate is fixedly connected inside the fixing frame. The fixing frame enhances the support strength of the vertical plate and prevents the vertical plate from deforming due to the sliding pressure of the mounting plate.

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.
[0017] This utility model provides a technical solution: Example

The shock absorption mechanism 2 includes a sliding rod 27, which is slidably connected to both sides of the bottom of the housing 1. A universal wheel 201 is fixedly connected to the bottom of the sliding rod 27. A spring 24 is sleeved on the surface of the sliding rod 27. A fixing ring 22 is provided at the bottom of the spring 24. The fixing ring 22 is fixedly connected to the surface of the sliding rod 27. A connecting rod 26 is fixedly connected between the two sliding rods 27.
[0019] Furthermore, a mounting bracket 25 is slidably connected to the surface of the sliding rod 27. The mounting bracket 25 is fixedly connected to the bottom of the housing 1. The sliding rod 27 can slide inside the mounting bracket 25, providing a vertical movement track for the sliding rod 27.
[0020] Furthermore, a mounting plate 202 is fixedly connected to the surface of the sliding rod 27. A groove is provided in the mounting plate 202, and a vertical plate 23 is slidably connected in the groove. A fixing member 29 is fixedly connected to the bottom of the vertical plate 23. The fixing member 29 is fixedly connected to the bottom of the housing 1. The cooperation of the mounting plate 202, the groove and the vertical plate 23 further restricts the movement trajectory of the sliding rod 27, prevents it from tilting or twisting when moving vertically, and disperses the pressure on the sliding rod 27, thus extending the service life of the shock absorption mechanism 2.
[0021] Furthermore, a fixing frame 21 is fixedly connected to the top of the vertical plate 23. The fixing frame 21 is fixedly connected to the inner wall of the housing 1. A connecting plate 28 is fixedly connected inside the fixing frame 21. The fixing frame 21 enhances the support strength of the vertical plate 23 and prevents the vertical plate 23 from deforming due to the sliding pressure of the mounting plate 202.
[0022] Example 2: See Figure 4 Furthermore, based on Embodiment 1, the adjustment mechanism 3 includes a slide rail 35, which is fixedly connected to the left side of the housing 1. A pull rod 37 is slidably connected inside the slide rail 35. Limiting blocks 31 are fixedly connected to both sides of the pull rod 37. Limiting grooves are opened on both sides of the slide rail 35. The limiting blocks 31 are slidably connected to the limiting grooves. The slide rail 35 provides a telescopic track for the pull rod 37. The limiting blocks 31 slide within the limiting grooves of the slide rail 35, limiting the range of motion of the pull rod 37.
[0023] Furthermore, a placement plate 34 is fixedly connected to the surface of the slide rail 35. The placement plate 34 is fixedly connected to the left side of the housing 1. A first positioning plate 33 is fixedly connected to the surface of the placement plate 34. A second positioning plate 36 is fixedly connected to the surface of the pull rod 37. A cylinder 32 is fixedly connected between the first positioning plate 33 and the second positioning plate 36. The automatic adjustment of the pull rod 37 is achieved by the extension and retraction driving force of the cylinder 32, eliminating the need for manual stretching and improving ease of use. At the same time, the cylinder 32 can stably maintain the extension length of the pull rod 37, preventing it from retracting on its own.
[0024] Furthermore, two cylinders 32 are provided, which are symmetrically arranged on both sides of the pull rod 37. They provide driving force synchronously, ensuring that the pull rod 37 is evenly stressed on both sides, avoiding tilting or jamming of the pull rod 37 due to stress on one side, and improving the stability and service life of the adjustment mechanism 3.
[0025] In actual operation, when this device is used, the battery module 9 is first placed inside the housing 1 by the handle 6. At this time, the limiting member 5 is located at the four corners of the battery module 9, which can limit the battery module 9. After the battery module 9 is installed, the cover 4 can be closed to protect the battery. When it is necessary to pull the battery module 9, the cylinder 32 can be activated according to the user's height. Under the action of the cylinder 32, the pull rod 37 can be driven to slide inside the slide rail 35, so as to adapt to users of different heights and achieve the purpose of portability. When the device is moving, the pressure applied by the battery module 9 causes the sliding rod 27 to slide continuously at the bottom of the housing 1, and the vertical plate 23 slides continuously inside the groove opened in the mounting plate 202. Under the elastic potential energy of the spring 24, the bumps generated during the journey can be reduced, thereby achieving the purpose of shock absorption and preventing the battery pack from vibrating and malfunctioning during the carrying process, thus improving the safety performance of the pull rod 37 and the battery pack.
