Description

Technical Field

[0001] This utility model belongs to the field of solar panel charger technology, and relates to a buffer device for the outer shell of a solar panel charger. Background Technology

[0002] A solar panel charger is a device that uses electricity generated by solar energy to charge equipment. The main components of a solar panel charger include a solar panel, a control circuit board, and a battery. Solar panel chargers are widely used for charging outdoor devices such as mobile phones, tablets, cameras, and flashlights, especially in the wild or in environments where there are no other charging methods.

[0003] The solar panel charger housing is the external mounting shell of the solar panel charger. Existing solar panel charger housings lack cushioning devices. During outdoor activities such as hiking and camping, the solar panel charger may fall due to careless operation or unstable placement. Without cushioning devices, the housing cannot effectively absorb energy when subjected to impact, which can easily lead to damage to internal components. Therefore, we have made improvements to this issue and proposed a solar panel charger housing cushioning device. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the existing solar panel charger casing lacks a cushioning device. During outdoor activities such as hiking and camping, the solar panel charger may fall due to careless operation or unstable placement. The casing, lacking a cushioning device, cannot effectively absorb energy when subjected to impact, which can easily lead to damage to the internal components.

[0005] The present invention relates to a solar panel charger housing buffer device, comprising a first housing and a second housing. The bottom of the first housing and the second housing are connected to a connecting component. An elastic band is fixed to the inner side of both the first housing and the second housing. Two snap-fit ​​slots are formed on the top of the first housing. Snap-fit ​​components are installed at the two snap-fit ​​slots of the first housing. Snap-fit ​​rods are connected inside the snap-fit ​​slots. The ends of the two snap-fit ​​rods away from the first housing are installed on the same second housing. Two side buffer components are respectively installed on the outer sides of the first housing and the second housing.

[0006] The connecting assembly includes multiple connecting blocks, with two connecting blocks forming a group. Each group of connecting blocks has a hinge connected to its bottom via a first bolt. The three hinges are rotatably connected to the same rotating shaft. Rubber blocks are installed at both ends of the rotating shaft, and the same counterweight lead block is installed at the bottom of the two rubber blocks.

[0007] The snap-fit ​​assembly includes two snap-fit ​​blocks, the bottoms of which are mounted on the top of the same first housing. Each snap-fit ​​block has a sliding groove, and the same connecting rod is slidably connected within the two sliding grooves. Each end of the connecting rod is equipped with a return spring, and the other end of the return spring is fixed within the sliding groove.

[0008] The connecting rod is U-shaped, and two snap-fit ​​balls are installed at both ends of the snap-fit ​​rod.

[0009] The side buffer assembly includes mounting rods, four of which are mounted on the outer sides of the first and second housings. Four sliding cylinders are mounted on the mounting rods, and sliding sleeves are slidably connected to the sliding cylinders. Shock-absorbing springs are mounted on the sliding cylinders, with the end of the shock-absorbing spring away from the sliding cylinder mounted on the sliding sleeve. The same protective plate is mounted on the four sliding sleeves.

[0010] Sealing gaskets are installed on the first and second outer shells, and retrieval grooves are respectively opened on the outer sides of the first and second outer shells.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the device combines multiple functions such as drop protection, impact resistance, self-protection, stable fixation and side cushioning, so that it can provide reliable protection in various outdoor environments.

[0012] When the device is dropped, the counterweight leads cause it to fall downwards, reducing the impact on the non-counterweight end. This is because the counterweights better absorb and disperse the impact force upon landing. The rubber blocks on the counterweights provide an additional cushioning layer, further reducing damage to the device's internal components. The elastic band allows the device to automatically close after being impacted and opening, protecting the internal contents from damage. The snap-fit ​​assembly design allows the snap-fit ​​rod to slide into the snap-fit ​​groove when the device closes, achieving a secure snap-fit ​​fixation through the snap-fit ​​ball and return spring. This design not only improves the device's stability but also ensures that the outer shell will not easily open upon impact. The side cushioning components provide additional side protection; when the device tilts to the side, these components absorb the impact force, reducing damage to the outer shell or internal items.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Example 1

[0026] like Figures 1-6As shown, a solar panel charger housing buffer device includes a first housing 1 and a second housing 2. Connecting components are connected to the bottom of the first housing 1 and the second housing 2. Elastic bands 8 are fixed to the inner sides of both the first housing 1 and the second housing 2. Two snap-fit ​​slots 15 are formed on the top of the first housing 1. Snap-fit ​​components are installed at the two snap-fit ​​slots 15. Snap-fit ​​rods 14 are connected inside the snap-fit ​​slots 15. The ends of the two snap-fit ​​rods 14 away from the first housing 1 are installed on the same second housing 2. Two side buffer components are respectively installed on the outer sides of the first housing 1 and the second housing 2. The connecting components include multiple connecting blocks 3, with two connecting blocks 3 forming a group. A hinge 4 is connected to the bottom of each group of connecting blocks 3 via a first bolt 5. The same rotating shaft 23 is rotatably connected to the three hinges 4. Rubber blocks 6 are installed at both ends of the rotating shaft 23. A counterweight lead block 7 is installed at the bottom of the two rubber blocks 6. The weight of the counterweight lead block 7 is proportional to the weight of the first housing 1 and the second housing 2. The two outer shells 2 have the same weight. The snap-fit ​​assembly includes two snap-fit ​​blocks 9. The bottom of the two snap-fit ​​blocks 9 is installed on the top of the same first outer shell 1. The snap-fit ​​blocks 9 have sliding grooves 10. The same connecting rod 12 is slidably connected in the two sliding grooves 10. The two ends of the connecting rod 12 are respectively equipped with return springs 13. The other end of the return springs 13 is fixed in the sliding grooves 10. The connecting rod 12 is set in a U-shape. When the first outer shell 1 is separated from the second outer shell 2, only the connecting rod 12 needs to be pulled. The connecting rod 12 drives the snap-fit ​​ball 11 to release the snap-fit ​​rod 14. The weight of the second outer shell 2 and the first outer shell 1 is used to unfold the shell. The two ends of the snap-fit ​​rod 14 are equipped with two snap-fit ​​balls 11. The first outer shell 1 and the second outer shell 2 are equipped with sealing gaskets 16. The hinge 4 and the rotating shaft 23 in the connecting assembly allow the first outer shell 1 and the second outer shell 2 to form a V-shaped structure when falling. This structure can better disperse the impact force and reduce the shell cracking or damage.

[0027] During operation, if the device falls, since the counterweight 7 has the same weight as the first outer shell 1 and the second outer shell 2, the falling direction changes to one end of the counterweight 7 falling downwards. In mid-air, the first and second outer shells 1 and 2 rotate on the drive shaft via the hinge 4 on the connecting assembly, forming a V-shape. Upon impact with the ground, the counterweight 7 contacts the ground first, and the rubber block 6 connected to it provides initial cushioning. The impact force causes the first and second outer shells 1 and 2 to open rapidly and at a large angle via the hinge 4. This large-angle opening of the first and second outer shells 1 and 2 tightens the elastic band 8. The tightened elastic band 8, using its elasticity, closes the first and second outer shells 1 and 2. When shell 2 is closed with the first outer shell 1, the two snap-fit ​​rods 14 on the second outer shell 2 slide into the snap-fit ​​groove 15 on the first outer shell 1. Since one end of the snap-fit ​​rod 14 is arc-shaped when it enters the snap-fit ​​groove 15, it presses the two snap-fit ​​balls 11 on the snap-fit ​​assembly. This causes the snap-fit ​​balls 11 to drive the connecting rod 12 to slide upward in the sliding groove 10 while pressing the return spring 13. When the snap-fit ​​rod 14 has finished entering the snap-fit ​​groove 15, the connecting rod 12 moves the snap-fit ​​balls 11 downward through the elastic force of the return spring 13 in the moving groove and snaps them onto the snap-fit ​​rod 14. This fixes the first outer shell 1 and the second outer shell 2 when they are closed. After the first outer shell 1 and the second outer shell 2 are closed and fixed, the device tilts to the side, causing the first outer shell 1 or the second outer shell 2 to contact the ground. At this time, the side buffer on the first outer shell 1 or the second outer shell 2 provides side buffering.

[0028] When the device falls, the counterweight 7 causes it to tend to fall downwards at one end, which helps reduce the impact on the non-counterweight end. This is because the counterweight 7 can better absorb and disperse the impact force upon landing. The rubber block 6 on the counterweight 7 provides an additional buffer layer, further reducing the impact damage to the inside of the device. The elastic band 8 allows the device to automatically close after being impacted and opening, thus protecting the internal items from damage. The design of the snap-fit ​​assembly allows the snap-fit ​​rod 14 to slide into the snap-fit ​​groove 15 when the device is closed, and achieves a stable snap-fit ​​fixation through the action of the snap-fit ​​ball 11 and the return spring 13. This design not only improves the stability of the device, but also ensures that the outer shell will not easily open when impacted. The side buffer assembly provides additional side protection. When the device tilts to the side, these components can absorb the impact force, reducing damage to the outer shell or the internal items.

[0029] Example 2

[0030] like Figures 3-6As shown, the side buffer assembly includes mounting rods 17. Four mounting rods 17 are mounted on the outside of the first housing 1 and the second housing 2. Four sliding cylinders 18 are mounted on the mounting rods 17. Sliding sleeves 19 are slidably connected to the sliding cylinders 18. Shock-absorbing springs 20 are mounted on the sliding cylinders 18. The shock-absorbing springs 20 not only absorb the impact, but also help the device return to its original state after the impact, maintaining the stability of the device and its ability to continue working. The end of the shock-absorbing spring 20 away from the sliding cylinder 18 is mounted on the sliding sleeve 19. The same protective plate 21 is mounted on the four sliding sleeves 19. Retrieval slots 22 are respectively opened on the outside of the first housing 1 and the second housing 2.

[0031] During operation, the device tilts to the side, causing either the first outer shell 1 or the second outer shell 2 to contact the ground. The protective plate 21 is the first to be impacted, and the impact causes the protective plate 21 to drive the sliding sleeve 19 to slide on the sliding cylinder 18. This sliding action allows the device to have a certain deformation space, thereby initially absorbing the impact energy. At the same time, the shock-absorbing spring 20 inside the sliding sleeve 19 is compressed, further absorbing and dispersing the impact force, reducing the impact energy transmitted to the first outer shell 1 and the second outer shell 2. Through the combined action of the sliding sleeve 19 and the shock-absorbing spring 20, the side buffer assembly can significantly reduce the impact force on the outer shell, effectively reducing damage to the outer shell and internal components.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
