Description

Technical Field

[0001] The utility model relates to the technical field of power supply, in particular to an impact-resistant power supply structure. Background Art

[0002] The power structure is the physical structure of the power supply. Different power structures can be selected according to actual needs. Different power structures have their own advantages and disadvantages. Users can choose a suitable power structure according to the use environment and actual needs of the appliance. The power structure provides power to electronic devices to ensure their normal operation. However, due to the limitations of the traditional installation method of the power structure, the power structure is inconvenient to disassemble and assemble, affecting the normal use of users.

[0003] The Chinese authorized announcement number is CN 209402192 U. An anti-collision mobile power supply. When the mobile power supply falls to the ground, the rubber clamping block and the metal sheet on the rubber clamping block contact the ground, the metal sheet and the rubber clamping block deform, thereby extending the impact time of the battery pack and reducing the impact on the battery pack.

[0004] However, this patent still has certain shortcomings when in use. The traditional power supply structure adopts an integrated molding structure. When the internal battery components are damaged and need to be replaced, it is not easy to disassemble and replace, which affects the normal use of the user. In addition, the existing power supply structure often uses metal gaskets to prevent impact. Although the metal sheet can have a buffering effect, it is easy to cause damage to the metal sheet after long-term use. It needs to be inspected regularly during use to prevent the metal sheet from breaking and failing to protect the power supply structure. Utility Model Content

At this time, the third spring is stretched, and the force generated by the rebound and the pressure generated by the second anti-collision plate offset each other, thereby achieving the effect of reducing the impact.

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, limiting holes 2 are provided on both sides of the protective shell 1, and a protective cover assembly 3 is provided on the top of the protective shell 1. The protective cover assembly 3 includes a protective cover body 301 located on the top of the protective shell 1, and a threaded hole 302 is provided on the side of the protective cover body 301. A bolt 303 is connected to the inner thread of the threaded hole 302, and a rubber pad 304 is fixedly connected to the bottom of the protective cover body 301.

[0028] Among them, the power supply structure is detachable by setting a protective shell 1, a limiting hole 2 and a protective cover assembly 3. Under normal conditions, the protective shell 1 and the protective cover body 301 are connected by bolts 303, and the bolts 303 and the protective cover body 301 are threadedly connected. The bolts 303 are screwed into the limiting holes 2 on the side of the protective shell 1 to fix the protective shell of the power supply structure. When the internal components need to be disassembled and replaced, the bolts 303 are screwed outward, the protective cover body 301 is moved up, and the first anti-collision plate 403 is moved around respectively, so that the power supply element 7 can be detached, thereby improving practicality.

[0029] In this embodiment, Figure 2 , Figure 4 and Figure 5 As shown, the first protective assembly 4 includes a fixed block 401 located inside the protective shell 1, a buffer chamber 402 is provided inside the fixed block 401, a piston rod 404 is slidably connected inside the buffer chamber 402, a second spring 406 is provided on the side of the piston rod 404, one end of the second spring 406 is elastically connected to the inner wall of the buffer chamber 402, the other end of the second spring 406 is elastically connected to the side of the piston rod 404, a first damping rod 407 is provided inside the second spring 406, a first spring 405 is provided outside the piston rod 404, one end of the first spring 405 is elastically connected to the fixed block 401, the other end of the first spring 405 One end is elastically connected to the first anti-collision plate 403, and the side of the piston rod 404 is fixedly connected to the first anti-collision plate 403. The second protective component 5 includes two sliders 501 slidably connected to the inner bottom wall of the protective shell 1, and the tops of the two sliders 501 are rotatably connected to the rotating blocks 502, and the tops of the rotating blocks 502 are rotatably connected to the rotating seat 503, and the tops of the rotating seat 503 are fixedly connected to the second anti-collision plate 504.

[0030] Among them, by providing the rubber pad 304, the first protection component 4 and the second protection component 5, the protection of the power supply structure is achieved. When there is a horizontal impact, the first anti-collision plate 403 provided inside the protective shell 1 is squeezed, so that the first spring 405 and the second spring 406 are squeezed by the first anti-collision plate 403, and the piston rod 404 slides in the buffer chamber 402. At the moment of squeezing, the rebound force generated by the first spring 405 and the second spring 406 respectively supports the first anti-collision plate 403 and the piston rod 404, thereby minimizing the impact received by the power supply element 7. When subjected to a vertical impact, the power supply element 7 moves downward, and the second anti-collision plate 504 also generates pressure downward, thereby driving the rotating block 502 to rotate, and driving the two sliders 501 to move in opposite directions in the sliding groove 6. At this time, the third spring 506 is stretched, and the force generated by the rebound and the pressure generated by the second anti-collision plate 504 offset each other, thereby achieving the effect of reducing the impact. When the power supply element 7 moves upward, the rubber pad 304 buffers the power supply element 7.

By screwing the bolt 303, it is stuck in the limiting hole 2 on the side of the protective shell 1, thereby achieving the fixation of the protective shell of the power supply structure. When it is necessary to disassemble and replace the internal components, the bolt 303 is screwed outward, and the protective cover body 301 is moved up, and then the first anti-collision plate 403 is respectively moved around, thereby achieving the detachability of the power supply component 7. When there is a horizontal impact, the first anti-collision plate 403 arranged inside the protective shell 1 is squeezed, so that the first spring 405 and the second spring 406 are affected by the first anti-collision plate 403. The squeezing force of the collision plate 403 and the piston rod 404 slide in the buffer chamber 402. At the moment of squeezing, the rebound force generated by the first spring 405 and the second spring 406 respectively supports the first anti-collision plate 403 and the piston rod 404, thereby minimizing the impact received by the power supply element 7. When subjected to a vertical impact, the power supply element 7 moves downward, and the second anti-collision plate 504 also generates downward pressure, thereby driving the rotating block 502 to rotate, and driving the two sliders 501 to move in opposite directions in the sliding groove 6. At this time, the third spring 506 is stretched, and the force generated by the rebound and the pressure generated by the second anti-collision plate 504 offset each other, thereby achieving the effect of reducing the impact. When the power supply element 7 moves upward, the rubber pad 304 buffers the power supply element 7.
