Description

Technical Field

[0001] The present invention relates to the technical field of energy storage, and particularly to an energy storage power supply. Background Art

[0002] In order to facilitate the handling of the energy storage power supply, a rotatable handle structure is usually provided on the housing of the energy storage power supply. In order to facilitate the handle structure to stay at a designated position when rotated to that position for convenient hand-holding by the user, a damping structure is usually provided on the rotating shaft of the handle structure. The damping effect of this damping structure depends on the interference fit between the rotating shaft and the silicone gasket. However, the tolerance range and the difference in soft hardness of the silicone gasket will significantly affect the stability and consistency of the damping. In addition, the existing silicone gaskets are often arranged inside the housing of the energy storage power supply. The rotating shaft is inserted into the housing through a through hole provided on the housing to cooperate with the silicone gasket. The through hole causes the interior of the housing to be directly connected to the outside, increasing the risk of water ingress. The inventor has realized that a new structure is needed that can both ensure the waterproof performance of the energy storage power supply and maintain the damping characteristics of the handle structure. Summary of the Invention

[0003] The first object of the present invention is to provide an energy storage power supply, the handle of which can achieve a smooth and stable damping effect, solve the problem of unstable traditional damping, improve the user experience, and the energy storage power supply has good waterproof performance.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] The present invention discloses an energy storage power supply, including: a housing, on which a blind hole is provided; a handle body, which has a mounting hole; a rotating shaft, which passes through the mounting hole and includes a first shaft section and a second shaft section, the second shaft section passes out of the mounting hole and is used to connect with the blind hole; a gasket and an elastic pad, the gasket and the elastic pad are arranged on the second shaft section and are clamped between the first shaft section and the handle body.

[0006] In some embodiments, the mounting hole includes a first hole and a second hole, the second hole is used to accommodate the second shaft section, the first hole is used to accommodate the first shaft section, a step surface is formed at the connection of the first hole and the second hole, and the gasket and the elastic pad are clamped between the step surface and the first shaft section.

[0007] In some embodiments, a threaded portion is provided at one end of the rotating shaft passing out of the mounting hole, the blind hole is provided with threads, and the threaded portion is threadedly connected to the blind hole.

[0008] In some specific embodiments, a stop plane is provided at the starting end of the threaded portion, and the stop plane is used to stop against the housing.

[0009] In some embodiments, the handle structure further includes a sealing gasket, which is sleeved on the rotating shaft and clamped between the handle body and the housing.

[0010] In some specific embodiments, the sealing gasket is attached to the handle body, and the handle body and the housing clamp and compress the sealing gasket.

[0011] In some embodiments, there is a fitting gap between the outer sidewall of the rotating shaft and the inner sidewall of the mounting hole, and the handle body is rotatable relative to the rotating shaft.

[0012] In some embodiments, the handle body includes a handle portion and two connecting portions. The two connecting portions are respectively connected to both ends of the handle portion, and each connecting portion is provided with a mounting hole.

[0013] In some embodiments, the elastic gasket is an arc-shaped washer, which contacts the handle body, and the gasket contacts the first shaft segment.

[0014] In some embodiments, a rotating groove is provided on the housing, and the handle body is rotatably connected in the rotating groove.

[0015] Advantageous effects of the energy storage power supply of the present invention: During the actual working process, the gasket and the elastic gasket provided on the handle body act as damping structures. The rotating shaft and the gasket apply pressure to the elastic gasket. When the handle body rotates, friction is generated between the gasket, the elastic gasket and the rotating shaft, hindering the rotation of the rotating shaft to form damping; the elastic gasket provides elastic force to ensure the stability of the damping force at different rotation angles. When the user operates, force needs to be applied to overcome the damping force to rotate the handle. After the external force disappears, the damping force keeps the handle in place. The gasket, the elastic gasket and the rotating shaft cooperate to generate resistance, promoting the friction between the handle body and related components, achieving a smooth and stable damping effect. Using the gasket and the elastic gasket as damping structures, the design solves the problem of unstable traditional damping and improves the user's operation experience. In addition, since the structure on the housing that cooperates with the rotating shaft is a blind hole, the phenomenon of external water vapor entering the interior of the housing is prevented, thereby improving the waterproof performance of the energy storage power supply in this embodiment.

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all the structures.

[0025] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0027] The present invention discloses an energy storage power supply. Refer to Figure 1 - Figure 2As shown in the figure, the energy storage power supply includes a handle structure 100 and a housing 200. A blind hole 220 is provided on the housing 200. The handle structure 100 includes a handle body 110, a rotating shaft 120, a gasket 130 and an elastic pad 140. The handle body 110 has a mounting hole 1121. The rotating shaft 120 passes through the mounting hole 1121 and includes a first shaft section 121 and a second shaft section 122. The second shaft section 122 passes out of the mounting hole 1121 and is used to connect with the blind hole 220. The gasket 130 and the elastic pad 140 are arranged on the second shaft section 121 and are clamped between the first shaft section 122 and the handle body 110. It can be understood that during the actual working process, the gasket 130 and the elastic pad 140 act as a damping structure. The rotating shaft 120 and the gasket 130 apply pressure to the elastic pad 140. When the handle body 110 rotates, a frictional force is generated between the gasket 130, the elastic pad 140 and the rotating shaft 120, hindering the rotation of the rotating shaft 120 to form damping. The elastic pad 140 provides elastic force to ensure the stability of the damping force at different rotation angles. When the user operates, a force needs to be applied to overcome the damping force to rotate the handle. After the external force disappears, the damping force keeps the handle in place. The gasket 130, the elastic pad 140 and the rotating shaft 120 cooperate to generate resistance, pushing the handle body 110 and related components to rub, achieving a smooth and stable damping effect. Using the gasket 130 and the elastic pad 140 as the damping structure, the design solves the problem of unstable traditional damping and improves the user's operation experience. In addition, since the structure on the housing 200 that cooperates with the rotating shaft 120 is a blind hole 220, the phenomenon of external water vapor entering the interior of the housing 200 is prevented, thereby improving the waterproof performance of the energy storage power supply in this embodiment.

[0028] Optionally, the elastic pad 140 is an arc-shaped washer. The arc-shaped washer contacts the handle body 110, and the gasket 130 contacts the first shaft section 121. It can be understood that choosing the arc-shaped washer as the elastic pad 140 and contacting the handle body 110 can give the rotating shaft 120 sufficient damping force during the rotation of the rotating shaft 120 and ensure the stability of the damping force at different rotation angles, thereby ensuring that the handle body 110 can be fixed in a specified position.

[0029] Reference Figure 4As shown, the mounting hole 1121 includes a first hole 11211 and a second hole 11212. The second hole 11212 is used to accommodate the second shaft segment 122, and the first hole 11211 is used to accommodate the first shaft segment 121. A stepped surface 11213 is formed at the connection of the first hole 11211 and the second hole 11212. The gasket 130 and the elastic pad 140 are clamped between the stepped surface 11213 and the first shaft segment 121. It can be understood that since the mounting hole 1121 forms a stepped hole, the first shaft segment 121 being received in the first hole 11211 can prevent the end of the rotating shaft 120 away from the housing 200 from protruding out of the handle body 110, thereby avoiding the housing 200 of the energy storage power supply having a protruding structure on its surface. While improving the aesthetic degree of the energy storage power supply, it can also prevent the user from being injured by the protruding structure. Clamping the gasket 130 and the elastic pad 140 between the stepped surface 11213 and the first shaft segment 121 can ensure that sufficient damping force is given to the rotating shaft 120 during the rotation process of the rotating shaft 120, and ensure that the damping force is stable at different rotation angles, thereby ensuring that the handle body 110 can be fixed at a designated position.

[0030] Optionally, referring to Figure 4 As shown, a threaded portion 123 is provided at the end of the rotating shaft 120 passing through the mounting hole 1121. The blind hole 220 is provided with threads, and the threaded portion 123 is threadedly connected to the blind hole 220. It can be understood that during assembly, the threaded portion 123 of the rotating shaft 120 is accurately screwed into the blind hole 220 through the mounting hole 1121 of the handle body 110. Using this simple and efficient connection method of threaded connection to realize the connection between the rotating shaft 120 and the housing 200 of the energy storage power supply not only realizes quick installation and disassembly, but also enables the rotating shaft 120 to bear the weight of the whole machine, demonstrating strong mechanical support performance with a simple structure, which is beneficial to improving the reliability of the entire energy storage power supply. In addition, it should be supplemented that in the prior art, a structure in which the rotating shaft is directly integrally formed with the handle by cold pressing or the like is used. This structure is extremely prone to plastic cracking due to stress concentration during the manufacturing process, seriously affecting the product quality and service life. In this embodiment, separating the rotating shaft 120 from the handle body 110 and manufacturing them separately is convenient for the manufacturing of the rotating shaft 120 and the handle body 110 on the one hand, and beneficial to improving the strength of the handle body 110 and extending its service life on the other hand. Of course, in other embodiments of the present invention, the blind hole 220 being provided with threads can be directly setting the blind hole 220 as a threaded hole, or embedding a nut in the blind hole 220.

[0031] Optionally, referring to Figure 4As shown, the handle structure 100 further includes a gasket 150. The gasket 150 is sleeved on the rotating shaft 120 and clamped between the handle body 110 and the housing 200. It can be understood that the main function of setting the gasket 150 between the handle body 110 and the housing 200 is to prevent dust and moisture from entering the housing 200, protect the housing 200 in all directions, ensure that its internal precision structure is not eroded, so as to facilitate the energy storage power supply to meet the IP66 standard of waterproof and dustproof.

[0032] Further optionally, the gasket 150 is attached to the handle body 110, and the handle body 110 and the housing 200 clamp and compress the gasket 150. It can be understood that after compressing the gasket 150, it can better prevent dust and moisture from entering the housing 200, protect the housing 200 in all directions, ensure that its internal precision structure is not eroded, so as to facilitate the energy storage power supply to meet the IP66 standard of waterproof and dustproof.

[0033] Further optionally, a stop plane is provided at the starting end of the threaded portion 123. The stop plane is used to abut against the housing 200. In the actual design process, through reasonable mechanical design, when the thread of the threaded portion 123 of the rotating shaft 120 is screwed into a preset depth, the limit mechanism is triggered (that is, the stop plane abuts against the side wall of the housing 200). At this time, the handle body 110 can apply a pre-pressure to the silicon gasket 150, so that the gasket 150 is tightly squeezed with the housing 200, and an efficient and reliable waterproof barrier can be constructed to effectively prevent moisture from invading.

[0034] Optionally, refer to Figure 1 As shown, a recess 1122 is provided on the side of the handle body 110 facing the housing 200, and the gasket 150 is installed in the recess 1122. It can be understood that installing the gasket 150 in the recess 1122 of the handle body 110 can make the side of the handle body 110 facing the housing 200 abut against the housing 200. This abutment is beneficial to improving the connection sealing performance between the handle body 110 and the housing 200, thereby further preventing external dirt from entering the housing 200 from the connection gap between the handle body 110 and the housing 200.

[0035] Optionally, there is a fitting gap between the outer side wall of the rotating shaft 120 and the inner side wall of the mounting hole 1121, and the handle body 110 is rotatable relative to the rotating shaft 120. It can be understood that the fitting gap between the rotating shaft 120 and the mounting hole 1121 can effectively prevent the handle body 110 from driving the rotating shaft 120 to rotate during the rotation process, thereby avoiding the loosening of the threaded portion 123 on the rotating shaft 120 during the rotation of the handle body 110.

[0036] Optionally, refer to Figure 1As shown, the handle body 110 includes a handle portion 111 and two connecting portions 112. The two connecting portions 112 are respectively connected to both ends of the handle portion 111, and each connecting portion 112 is provided with a mounting hole 1121. It can be understood that the handle body 110 includes a handle portion 111 and two connecting portions 112 connected in a U shape. On the one hand, it can improve the connection stability between the handle body 110 and the housing 200, ensuring that the handle body 110 can rotate stably relative to the housing 200. On the other hand, it is convenient for users to hold to carry the energy storage power supply.

[0037] Optionally, referring to Figure 3 As shown, the housing 200 is provided with a rotating groove 210, and the handle body 110 is rotatably connected in the rotating groove 210. It can be understood that the handle body 110 is rotatably connected in the rotating groove 210. When the handle structure 100 is not in use, the handle body 110 is accommodated in the rotating groove 210, making it integrated with the housing 200, which is beneficial to improving the aesthetic degree of the energy storage power supply. In addition, during actual use, the rotating groove 210 also limits the rotation space of the handle body 110, avoiding the phenomenon that the threaded portion 123 of the rotating shaft 120 becomes loose or the handle body 110 is damaged due to excessive rotation of the handle body 110.

[0038] Optionally, referring to Figure 3 As shown, the rotating groove 210 has a first arc-shaped side wall 211, and the surface of the handle body 110 facing the first arc-shaped side wall 211 is formed as a second arc-shaped side wall 1123. It can be understood that during the actual working process, when the user rotates the handle body 110, the second arc-shaped side wall 1123 can rotate relative to the first arc-shaped side wall 211. On the one hand, it facilitates the smooth rotation of the handle body 110. On the other hand, it is beneficial to reduce the wear between the handle body 110 and the housing 200, thereby extending the service life of the handle body 110 and the housing 200.

[0039] The advantages of the energy storage power supply of the present invention are as follows:

[0040] First, the independently designed T-shaped rotating shaft 120 is connected to the housing 200 by means of threaded connection, avoiding the stress concentration problem caused by cold-pressing an integrated rotating shaft, and effectively solving the plastic cracking caused by stress problems;

[0041] Second, the application of the high-performance gasket 150 makes the joint between the handle body 110 and the housing 200 meet the waterproof and dustproof IP66 standard, effectively extending the service life of the equipment and broadening the application scenarios of the product;

[0042] Thirdly, a frictional force is generated between the spacer 130, the elastic pad 140 and the rotating shaft 120 to hinder the rotation of the rotating shaft 120 to form damping; the elastic pad 140 provides elastic force to ensure the stability of the damping force at different rotation angles, replacing the conventional silicone damping and avoiding the problems of early-stage rebound and late-stage damping disappearance.

[0043] Fourthly, the installation and disassembly processes of the handle structure 100 are greatly simplified, the maintenance cost and time cost are reduced, and the maintainability and upgradability of the energy storage power supply are improved.

[0044] The installation process of the handle structure 100 of the present invention is as follows:

[0045] Firstly, the sealing gasket 150 (silicone waterproof gasket) is respectively pasted on the connecting portion 112 of the handle body 110 and arranged around the mounting hole 1121.

[0046] Secondly, the handle body 110 with the sealing gasket 150 is placed in the rotating groove 210 of the housing 200, and the mounting hole 1121 is made to correspond to the nut embedded in the housing 200.

[0047] Thirdly, the elastic pad 140 and the spacer 130 are sequentially sleeved on the first shaft section 121 of the rotating shaft 120, and the elastic pad 140 abuts against the second shaft section 122.

[0048] Fourthly, the rotating shaft 120 with the elastic pad 140 and the spacer 130 is inserted into the mounting hole 1121, and the rotating shaft 120 is rotated to lock the threaded portion 123 of the rotating shaft 120 with the nut to complete the assembly.
