Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and particularly relates to a handle assembly of an energy storage power supply and an energy storage power supply. Background Art

[0002] As a mobile small power supply station, the energy storage power supply is widely used. To facilitate the handling and transfer of the energy storage power supply, a movable handle is usually provided on the energy storage power supply. The movable handle of the energy storage power supply includes a handle main body and a handle rotating shaft. One end of the handle rotating shaft is inserted into the handle main body, and the other end passes through the box body of the energy storage power supply to realize the connection between the movable handle and the energy storage power supply. When transferring the energy storage power supply, the handle rotating shaft bears a certain weight.

[0003] When using the movable handle, it is necessary to rotate the movable handle to lift it. Among them, during the process of rotating the movable handle, in order to provide a better experience for users, the movable handle needs to have a certain damping effect, so that the movable handle will not directly fall during the rotation process, causing inconvenience.

[0004] However, the current handles are usually made of metal, plastic or other materials. After long-term use, these materials may age due to oxidation, wear, corrosion and other reasons, resulting in changes in the damping performance of the handle, thus presenting a damping degradation phenomenon and affecting the user experience.

[0010] In some embodiments, the compression member is a spring or a compression spring.

[0011] In some embodiments, a preset distance is reserved between the end of the plugging portion of the handle rotating shaft and the end of the rotating shaft hole or the mounting hole.

[0012] In some embodiments, an exhaust groove is provided on the handle body or the housing. The exhaust groove is provided at a position corresponding to the plugging portion.

[0035] The embodiments of the present utility model will be described in detail below.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0036] Please refer to Figures 1 to 3, this application provides a handle assembly 10 for an energy storage power supply 100. The energy storage power supply 100 includes a housing 20, and the handle assembly 10 is rotatably arranged on the housing 20. The handle assembly 10 includes a handle body 11, a compression member 12, and a handle rotating shaft 13. The handle body 11 is rotatably arranged on the housing 20 through the handle rotating shaft 13, and the compression member 12 is compressibly sleeved on the handle rotating shaft 13. During the rotation of the handle rotating shaft 13, the reaction force generated by the compression of the compression member 12 acts on the housing 20 or the handle body 11 along the axial direction of the handle rotating shaft 13, so as to generate rotational damping when the housing 20 and the handle body 11 rotate relative to each other.

[0037] Specifically, the overall handle assembly 10 can be in a U-shaped structure or a structure of other shapes, which is not limited herein.

[0038] It can be understood that in the related art, the handle in the energy storage power supply is separately arranged from the housing, which requires more material management and maintenance costs and increases the risk of dead stock.

[0039] In response to this, the handle assembly 10 of this application is rotatably arranged on the housing 20. That is, at this time, the handle assembly 10 can be integrally arranged with the housing 20, which can reduce the use of materials for manufacturing the energy storage power supply 100, reduce the material management and maintenance costs, and reduce the risk of dead stock. In addition, this application integrates the handle assembly 10 onto the housing 20, reducing the use of manufacturing materials for the energy storage power supply 100 and reducing the material management and maintenance costs.

[0040] In detail, for the energy storage power supply 100 of this application, the compression member 12 is first compressibly sleeved on the handle rotating shaft 13, and then the handle body 11 is rotatably arranged on the housing 20 through the handle rotating shaft 13, so as to realize the assembly process of rotatably arranging the handle assembly 10 on the housing 20. The handle body 11 with a hollow structure can achieve lightweight and effectively save the materials for manufacturing the handle assembly 10.

[0041] The compression member 12 is compressibly sleeved on the handle rotating shaft 13. The compression member 12 can be an elastic member, such as a spring or other elastic components, as long as it can be compressed to generate a reaction force, which is not limited herein.

[0042] It can be understood that in the related art, the damping effect of the handle of the energy storage power supply requires additional use of damping sheets, and the assembly of the handle of the energy storage power supply is relatively complex and costly.

[0043] The handle assembly 10 of the energy storage power supply of the present application does not require an additional damping sheet. Only by compressing the compression member 12, the generated reaction force is associated with the housing 20 or the handle body 11, and then the reaction force is converted into the damping force required when the housing 20 and the handle body 11 rotate relative to each other, achieving the damping effect of the handle assembly 10. The assembly of the handle assembly 10 of the energy storage power supply 100 is simple and the cost is low.

[0044] The handle rotating shaft 13 can be made of plastic material. In other embodiments, the handle rotating shaft 10 can also be made of other materials, which is not specifically limited herein. The handle rotating shaft 13 can be integrally formed by an injection molding process to ensure the overall continuity and structural strength of the handle rotating shaft 13.

[0045] The handle rotating shaft 13 can be cylindrical or other shapes, so as to ensure that the handle rotating shaft 13 is rotatably connected to the housing 20 and the handle body 11, which is not specifically limited herein.

[0046] Thus, the handle assembly 10 of the energy storage power supply 100 of the present application compresses the compression member 12, and the reaction force generated by the compression member 10 is associated with the housing 20 or the handle body 11, and then the reaction force is converted into the damping force required when the housing 20 and the handle body 11 rotate relative to each other, thereby generating the damping effect of the handle assembly 10, and the handle assembly 10 will not have physical irreversible phenomena, can always maintain the damping effect, and will not show damping degradation phenomena over time, improving the user experience.

[0047] Please refer to Figure 4 and Figure 5 , in some embodiments of the present application, the housing 20 is provided with a mounting hole 21, and a rotating shaft hole 111 is provided at a position corresponding to the mounting hole 21 on the handle body 11. The handle rotating shaft 13 passes through the mounting hole 21 and the rotating shaft hole 111 so that the handle body 11 is rotatably mounted on the housing 20. Among them, Figure 5 is Figure 4 the enlarged schematic view of the dashed part in

[0048] Among them, the diameters of the mounting hole 21 and the rotating shaft hole 111 can be the same, and the positions of the mounting hole 21 and the rotating shaft hole 111 correspond to each other.

[0049] The depth of the rotating shaft hole 111 is adapted to the length of the insertion of the handle rotating shaft 13. The depth of the rotating shaft hole 111 can be, for example, greater than or equal to half of the length of the handle rotating shaft 13, which is not limited herein.

[0050] For example, in one example, the handle rotating shaft 13 first passes through the mounting hole 21 and the rotating shaft hole 111, so that the handle body 11 is rotatably mounted on the housing 20. Specifically, the handle rotating shaft 13 can first pass through the mounting hole 21 on the housing 20, and then insert the handle rotating shaft 13 into the rotating shaft hole 111 of the handle body 111, so that the handle body 11 is rotatably mounted on the housing 20, thereby realizing the relative rotation between the handle assembly 10 and the housing 20.

[0051] In this way, the energy storage power supply 100 of the present application can be provided with a mounting hole 21 on the housing 20, and a rotating shaft hole 111 is provided at a position corresponding to the mounting hole 21 on the handle body 11. The handle rotating shaft 13 passes through the mounting hole 21 and the rotating shaft hole 111, so that the handle body 11 is rotatably mounted on the housing 20, thereby realizing the relative rotation between the handle assembly 10 and the housing 20, and at the same time realizing the integrated setting of the handle assembly 10 and the housing 20, thereby reducing the material use for manufacturing the energy storage power supply 100, reducing the control and maintenance costs of the materials, and reducing the risk of dead stock.

[0052] In some embodiments, the handle rotating shaft 13 first passes through the mounting hole 21 and then has an interference fit with the rotating shaft hole 111.

[0053] Specifically, please refer to Figure 5 , in one embodiment, the handle rotating shaft 13 includes a resisting portion 131 and a plugging portion 132. The plugging portion 132 has an interference fit with the rotating shaft hole 111, and the compression member 12 resists the resisting portion 131 and generates a reaction force acting on the housing 20.

[0054] That is to say, the handle rotating shaft 13 can have an interference fit with the handle body 11, and a clearance fit between the handle rotating shaft 13 and the housing 20. The handle rotating shaft 13 is rotatably connected relative to the housing 20. At this time, the reaction force of the compression member 12 can act on the housing 20 to generate rotational damping.

[0055] Alternatively, the handle rotating shaft 13 first passes through the rotating shaft hole 111 and then has an interference fit with the mounting hole 21.

[0056] Specifically, in another embodiment, the handle rotating shaft 13 includes a resisting portion 131 and a plugging portion 132. The plugging portion 132 has an interference fit with the mounting hole 21, and the compression member 12 resists the resisting portion 131 and generates a reaction force acting on the handle body 11.

[0057] That is to say, the handle rotating shaft 13 can have a clearance fit with the handle body 11, and an interference fit between the handle rotating shaft 13 and the housing 20. The handle body 11 is rotatably connected relative to the handle rotating shaft 13. At this time, the reaction force of the compression member 12 can act on the handle body 11 to generate rotational damping.

[0058] Understandably, among different energy storage power supplies 100, due to differences in the size and weight of the handle assembly 10, the force arms for rotation are different, resulting in inconsistent damping effects. In this application, by adjusting the compression amounts of the compression members 12 differently, the handle assemblies 10 of different energy storage power supplies 100 can achieve damping effects with the same damping force.

[0059] In some embodiments, the compression amount of the compression member 12 changes with the size and weight of the handle rotating shaft 13. Thus, for the handle assembly 10 of the energy storage power supply 100 in this application, by adjusting the compression amount of the compression member 12, damping effects with different damping forces can be achieved.

[0060] In addition, since the compression amount of the compression member 12 can be adjusted, the energy storage power supply 100 in this application can adjust the damping forces of handle assemblies 10 with different weights and sizes to be the same, achieving the same damping effect.

[0061] For example, when the size and weight of the handle rotating shaft A1 are relatively large, the compression amount of the compression member A2 sleeved on the handle rotating shaft A1 can also be set to a relatively large value; when the size and weight of the handle rotating shaft B1 are relatively small, the compression amount of the compression member B2 sleeved on the handle rotating shaft B1 can also be set to a relatively large value, so that the large handle assembly A composed of the handle rotating shaft A1 and the compression member A2 and the small handle assembly B composed of the handle rotating shaft B1 and the compression member B2 can achieve damping effects with the same damping force.

[0062] As Figure 5 shown, in some embodiments, a preset distance d is reserved between the end of the insertion portion 132 of the handle rotating shaft 13 and the end of the rotating shaft hole 111. The length of the preset distance d can be, for example, 0.5 cm, 0.6 cm, 0.8 cm, 1 cm, 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm or 1.6 cm, which is not limited here. Alternatively, a preset distance d is reserved between the end of the insertion portion 132 of the handle rotating shaft 13 and the end of the mounting hole 111.

[0063] Understandably, in the handle assembly 10 of this application, a certain distance is reserved between the handle rotating shaft 13 and the end of the handle assembly 10. By reserving the preset distance d, after the compression member 12 is sleeved on the handle rotating shaft 13 and the handle rotating shaft 13 sleeved with the compression member 12 is assembled with the handle body 11, the handle rotating shaft 13 can be screwed into the reserved space of the preset distance d, thereby increasing the compression amount of the compression member 12.

[0064] Alternatively, after the compression member 12 is sleeved on the handle rotating shaft 13, and after the handle rotating shaft 13 sleeved with the compression member 12 is assembled with the handle body 11, the handle rotating shaft 13 can be screwed out a certain distance, so as to adjust the compression amount of the compression member 12 to become smaller.

[0065] Please refer to Figure 6 and Figure 7 , at least one strengthening rib position 22 is provided on the housing 20. The strengthening rib position 22 is arranged at the contact part between the housing 20 and the handle rotating shaft 13. At least one strengthening barb 133 is provided on the handle rotating shaft 13. There is no clearance fit or interference fit between the strengthening barb 133 and the strengthening rib position 22. Among them, Figure 7 is Figure 6 an enlarged schematic view of the dotted line part in

[0066] Specifically, at least one strengthening rib position 22 is provided on the housing 20, and at least one strengthening barb 133 is provided on the handle rotating shaft 13. That is to say, one strengthening rib position 22 can be provided on the housing 20, or multiple strengthening rib positions 22 can be provided. As Figure 7 shown, one strengthening barb 133 can be provided on the handle rotating shaft 13, or multiple strengthening barbs 133 can be provided. When only one strengthening rib position 22 is provided on the housing 20, correspondingly, only one strengthening barb 133 is provided on the handle rotating shaft 13, so that one strengthening rib position 22 and one strengthening barb 133 are arranged in a matching manner. When multiple strengthening rib positions 22 are provided on the housing 20, correspondingly, multiple strengthening barbs 133 are also provided on the handle rotating shaft 13, so that multiple strengthening rib positions 22 and multiple strengthening barbs 133 are arranged in a matching manner.

[0067] The matching methods between the strengthening barb 133 and the strengthening rib position 22 include two methods: clearance fit and interference fit. When the strengthening barb 133 and the strengthening rib position 22 are in a clearance fit manner, the cooperation between the handle rotating shaft 13 and the housing 20 can be made firm. When the strengthening barb 133 and the strengthening rib position 22 are in an interference fit manner, the cooperation between the handle rotating shaft 13 and the housing 20 can be made more firm. The strengthening barb 133 can be an inverted triangle or other shapes, which is not limited here.

[0068] That is to say, the interference fit between the strengthening barb 133 of the handle rotating shaft 13 and the strengthening rib position 22 of the housing 20 in this application can solve the problem of the handle rotating shaft 13 falling off due to failure, and form the second protection of the handle assembly 10.

[0069] Please refer to Figure 8 and Figure 9, an exhaust groove 112 is provided on the handle body 11 or the housing 20. The exhaust groove 112 is disposed at a position corresponding to the insertion portion 132. The exhaust groove 112 is used to discharge the air in the rotation shaft hole 111 or the mounting hole 21 when the insertion portion 132 is inserted into the rotation shaft hole 111 or the mounting hole 21. Among them, Figure 9 is Figure 8 an enlarged schematic view of the dashed part in

[0070] Specifically, the handle body 11 may be in a U-shaped structure or other shapes, which is not limited herein. Rotation shaft holes 111 are provided on one sides of the two ends of the handle body 11 facing each other. In other embodiments, the rotation shaft hole 111 may have a taper in a first direction, and the first direction is the depth direction of the rotation shaft hole 111. That is, the diameter of the rotation shaft hole 111 gradually decreases in the first direction, and the hole wall of the rotation shaft hole 111 may have a draft angle in the first direction. The handle rotation shaft 13 includes an insertion portion 133, and the insertion portion 133 is inserted into the rotation shaft hole 111 to realize the connection between the handle rotation shaft 13 and the handle body 11.

[0071] It can be understood that when the handle rotation shaft 13 is inserted into the rotation shaft hole 111 or the mounting hole 21 and pressed to a certain depth, the air in the rotation shaft hole 111 or the mounting hole 21 of the handle body 11 is not easily discharged outside the energy storage power supply 100, and it is easy to cause the air in the energy storage power supply 100 not to come out, resulting in a phenomenon that there is compressed air inside the rotation shaft hole 111. The compressed air will cause a reverse thrust on the handle rotation shaft 13 in the rotation shaft hole 111, which is likely to cause defects in the handle assembly 10 and affect the user experience.

[0072] When the insertion portion 132 of the handle rotation shaft 13 is inserted into the rotation shaft hole 111 or the mounting hole 21 of the handle body 11, the exhaust groove 112 provided on the handle body 11 or the housing 20 can discharge the air in the rotation shaft hole 111 or the mounting hole 21, thereby avoiding the phenomenon of compressed air existing in the rotation shaft hole 111 or the mounting hole 21 and avoiding causing defects in the handle assembly 10 and affecting the user experience. Figure 8 In

[0073] That is to say, when the handle rotation shaft 13 and the rotation shaft hole 111 of the handle body 11 are in interference fit, an exhaust groove 112 can be provided on the handle body 11. When the handle rotation shaft 13 and the mounting hole 21 of the housing 20 are in interference fit, an exhaust groove 112 can be provided on the housing 21.

[0074] In addition, since there may be a small amount of unevenness or sharp protrusions at the closed ends of both ends of the compression member 12, such as direct contact with the housing plastic of the housing 20, under the interaction of the rotational force and the compression direction force, there is a certain risk that the compression body gets stuck in the housing plastic of the housing 20, resulting in damping failure of the handle assembly 10 of the energy storage power supply 100.

[0075] In addition, the damping force caused by the torque of the compression member 12 in the energy storage power supply 100 of the present application can be uniformly maintained, providing a better user experience. Since the damping effect of the handle assembly 10 can be achieved by using the reaction force generated by the compression of the compression member 12, the compression member 12 can be directly sleeved on the handle rotating shaft 13 without using a large number of parts to fix the compression member 12 on the handle rotating shaft 13. Therefore, the labor input for assembling the handle insert and the handle silicone can be reduced, the assembly process of the handle assembly 10 is optimized, and the assembly efficiency of the handle assembly 10 is improved.

[0076] Therefore, please refer to Figure 2 、 Figure 4 and Figure 5 In some embodiments of the present application, the handle assembly 10 may further include a washer 14. The washer 14 is sleeved on the handle rotating shaft 13. One side of the washer 14 abuts against the spring, and the other side of the washer 14 abuts against the handle body 11 or the housing 20. The washer 14 may be a flat washer in the shape of a Figure 2 as shown in the figure.

[0077] In the present application, a washer 14 is sleeved between the compression member 12 and the housing 20, which can reduce the damage to the housing plastic of the housing 20 caused by the rotation of the compression member 12 during use and extend the service life of the handle assembly 10.

[0078] In some embodiments of the present application, the handle rotating shaft 13 and the handle body 11 are cold-pressed and fixed by a cold-pressed rotating shaft process.

[0079] It can be understood that when the handle rotating shaft 13 and the handle body 11 are fixed together by processes such as sleeve-pressing and hot melting, since it involves the heating and cooling processes of the handle rotating shaft 13, thermal stress is easily generated. Thermal stress is the stress generated due to the uneven internal temperature distribution of the handle rotating shaft 13, resulting in inconsistent thermal expansion or contraction of each part. When this stress exceeds the strength limit of the handle rotating shaft 13, the handle rotating shaft 13 will crack or be damaged.

[0080] In the present application, the handle rotating shaft 13 and the handle body 11 are fixed by a cold-pressed rotating shaft process. Since the cold-pressing process is carried out at room temperature and does not require heating of the handle rotating shaft 13, the generation of thermal stress is fundamentally avoided, thereby solving the thermal stress problem generated by fixing the handle rotating shaft 13 and the handle body 11 by sleeve-pressing and hot melting processes, and thus avoiding the phenomenon of cracking of the handle rotating shaft 13.

[0081] The present application also provides an energy storage power supply 100. The energy storage power supply 100 includes the handle assembly 10 of any one of the above embodiments. The structure of the handle assembly 10 is as described above and will not be elaborated here.

[0082] Specifically, please combineFigures 1 to 3 In one embodiment, when assembling the energy storage power supply 100, first, the handle body 11 of the handle assembly 10 is sleeved on the housing 20, and then the handle rotating shaft 13 is inserted through the compression member 12 and the washer 14. After that, the handle rotating shaft 13 of the assembled compression member 12 and washer 14 is passed through the mounting hole 21 of the housing 20 until the handle rotating shaft 13 is inserted into the rotating shaft hole 111 of the handle body 11. Finally, the handle rotating shaft 13 and the handle body 11 are cold-pressed and fixed together through the cold-pressing rotating shaft process, and the assembly is completed.

[0083] In this way, the handle assembly 10 of the energy storage power supply 100 of the present application compresses the compression member 12, and the reaction force generated by the compression member 10 is associated with the housing 20 or the handle body 11, and then the reaction force is converted into the damping force required when the housing 20 and the handle body 11 rotate relative to each other, thereby generating the damping effect of the handle assembly 10, and the handle assembly 10 will not have physical irreversible phenomena, can always maintain the damping effect, and will not show damping degradation over time, improving the user experience.
