[0040] Please refer to Figure 1 , Figure 2 and Figure 3 . The handle assembly 100 of the present application is used in an energy storage power supply 1000, which includes a housing 1001, and the handle assembly 100 is rotatably arranged on the housing 1001. The handle assembly 100 includes a handle shaft 10, a handle body 20, and a compression member 30. The handle shaft 10 includes a first limiting portion 11. The handle body 20 is rotatably arranged on the housing 1001 through the handle shaft 10. The compression member 30 is compressibly sleeved on the handle shaft 10, and a first end 31 of the compression member 30 is fixed to the first limiting portion 11. During rotation of the handle shaft 10, the reaction force generated by compression of the compression member 30 acts on the housing 1001 or the handle body 20 along the axial direction of the handle shaft 10, so that rotation damping is generated when the housing 1001 and the handle body 20 rotate relative to each other.

[0041] In the handle assembly 100 of the present application, since the first end 31 of the compression member 30 is fixed to the first limiting portion 11, the first limiting portion 11 can limit the position of the compression member 30 during rotation of the handle shaft 10, so that the compression member 30 can rotate together with the handle shaft 10. This can prevent relative sliding between the compression member 30 and the handle shaft 10, thereby preventing vibration of the compression member 30 and further preventing noise generation of the handle assembly 100 during use.

[0042] In addition, during rotation of the handle shaft 10, the reaction force generated by compression of the compression member 30 acts on the housing 1001 or the handle body 20 along the axial direction of the handle shaft 10, thereby generating rotation damping. This rotation damping can effectively reduce the free rotation of the handle assembly 100 when it is not subjected to artificial force, improve the stability of the handle assembly 100, and prevent disordered swinging of the handle assembly 100 due to vibration or collision during handling.

[0043] Specifically, the handle assembly 100 as a whole can be in a U-shaped structure or other shaped structure, which is not limited herein. In the energy storage power supply 1000, the handle assembly 100 can facilitate the user to carry or move the energy storage power supply 1000.

[0044] The energy storage power supply 1000 is a device capable of storing and releasing electric energy when needed. The energy storage power supply 1000 can be a collection of battery packs, super capacitors and other energy storage elements, and the shell 1001 of the energy storage power supply 1000 is used to protect the internal energy storage elements.

[0045] It can be understood that in the related art, the handle in the energy storage power supply 1000 is arranged separately from the shell 1001, which requires more material control and maintenance costs, and increases the risk of idle materials. In this regard, the handle assembly 100 of the present embodiment can be rotatably arranged on the shell 1001. That is, the handle assembly 100 can be integrally arranged with the shell 1001 at this time, which can reduce the use of materials for manufacturing the energy storage power supply 1000, reduce the material control and maintenance costs, and reduce the risk of idle materials.

[0046] The handle shaft 10 can serve as the center shaft of the handle main body 20 rotation, so that the handle main body 20 can be flexibly rotated on the shell 1001. For example, when the user exerts force to rotate the handle main body 20, the handle shaft 10 bears the torque of rotation and ensures the smooth rotation of the handle main body 20. The handle shaft 10 can be made of stainless steel, aluminum alloy or other metal materials, which have good strength and corrosion resistance, and can ensure the performance stability of the handle shaft 10 in the long-term use process. The handle shaft 10 can also be made of plastic material. The handle shaft 10 can be integrally formed by injection molding process to ensure the overall continuity and structural strength of the handle shaft 10.

[0047] The handle shaft 10 can be cylindrical or other shapes to ensure that the handle shaft 10 is rotatably connected with the shell 1001 and the handle main body 20, which is not specifically limited herein.

[0048] The handle main body 20 can be a hollow structure, which can realize lightweight and effectively save materials for manufacturing the handle assembly 100, thereby reducing the manufacturing cost.

[0049] In the assembly process, the compression member 30 is first compressibly sleeved on the handle shaft 10, and then the handle main body 20 is rotatably arranged on the shell 1001 through the handle shaft 10, thereby realizing the assembly process of the handle assembly 100 rotatably arranged on the shell 1001.

[0050] It can be understood that the damping effect of the handle of the energy storage power supply 1000 in the related art needs to be additionally matched with a damping sheet, and the assembly of the handle of the energy storage power supply 1000 is relatively complex and has a high cost.

[0051] The handle assembly 100 of the energy storage power supply 1000 in the utility model embodiment does not need to be additionally configured with a damping sheet, and only through compression of the compression member 30, the reaction force generated is associated with the shell 1001 or the handle main body 20, and then the reaction force is converted into the damping force required when the shell 1001 and the handle main body 20 rotate relative to each other, so that the damping effect of the handle assembly 100 is realized. Therefore, the assembly of the handle assembly 100 of the energy storage power supply 1000 in the utility model embodiment is simple and has a low cost.

[0052] The handle assembly 100 compresses the compression member 30, the reaction force generated by the compression member 30 is associated with the shell 1001 or the handle main body 20, and then the reaction force is converted into the damping force required when the shell 1001 and the handle main body 20 rotate relative to each other, so that the damping effect of the handle assembly 100 is generated, and the handle assembly 100 will not have a physical irreversible phenomenon, and can always maintain the damping effect and will not have a damping degradation phenomenon with the extension of time, thereby improving the user experience.

[0053] In addition, the damping degree caused by the torsion of the compression member 30 in the energy storage power supply 1000 in the utility model embodiment can be uniformly maintained, and the user experience is better. Since the reaction force generated by compression of the compression member 30 can realize the damping effect of the handle assembly 100, the compression member 30 can be directly sleeved on the handle shaft 10, and a large number of parts are not needed to fix the compression member 30 on the handle shaft 10, so that the labor input for assembling the handle plug and the handle silica gel can be reduced, the assembly process of the handle assembly 100 is optimized, and the assembly efficiency of the handle assembly 100 is improved.

[0054] The compression member 30 can be an elastic member, such as a spring, a rubber ring or other elastic components, and can be compressed to generate a reaction force, which is not limited herein.

[0055] The first limiting portion 11 can be a welding portion, an adhesive portion or a riveting portion, etc. The compression member 30 can be fixed to the first limiting portion 11 by welding, adhesive or riveting, etc. For example, the first limiting portion 11 is coated with a structural adhesive, and the compression member 30 can be adhered to the first limiting portion 11 by the structural adhesive.

[0056] The first limiting portion 11 can also be a protrusion, a groove, a threaded hole, etc. to fix the first end 31 of the compression member 30 to the first limiting portion 11 by clamping or using a bolt, a screw, etc. For example, the first limiting portion 11 is provided with a threaded hole, and the first end 31 of the compression member 30 is correspondingly provided with a threaded hole. The compression member 30 is fixed to the first limiting portion 11 by using a screw, so that the compression member 30 can rotate together with the handle shaft 10 during rotation of the handle shaft 10.

[0057] It can be understood that, during rotation of the handle shaft 10, if the compression member 30 is not fixed, the compression member 30 can not rotate with the handle shaft 10, so that relative sliding occurs between the compression member 30 and the handle shaft 10. In the case of high rotation speed, the compression member 30 can even vibrate, causing the compression member 30 to hit the handle shaft 10, thereby generating a large noise.

[0058] By fixing the first end 31 of the compression member 30 to the first limiting portion 11, the compression member 30 can rotate together with the handle shaft 10 during rotation of the handle shaft 10. In this way, relative sliding does not occur between the compression member 30 and the handle shaft 10, so that vibration of the compression member 30 is eliminated, thereby eliminating noise generated during use of the handle assembly 100.

[0059] Please refer to Figure 3 In some embodiments, the first limiting portion 11 is provided with a first limiting groove 110, and the first end 31 of the compression member 30 is embedded in the first limiting groove 110.

[0060] In this way, the first limiting groove 110 not only can be used to limit the position of the first end 31 of the compression member 30, but also can reduce the consumption of materials during manufacturing of the handle shaft 10, thereby reducing the manufacturing cost of the handle shaft 10. In addition, embedding the first end 31 of the compression member 30 in the first limiting groove 110 helps to improve the installation precision of the compression member 30. During production, the first limiting groove 110 can serve as a reference datum to ensure the correct installation position and direction of the compression member 30.

[0061] Specifically, the first limiting groove 110 is a groove-shaped structure provided on the first limiting portion 11 and used to embed the first end 31 of the compression member 30. The first limiting groove 110 can be a circular groove, a square groove, etc. and can be adaptively provided according to the shape of the first end 31 of the compression member 30. When the handle shaft 10 rotates rapidly, the first limiting groove 110 can tightly clamp the first end 31 of the compression member 30, thereby eliminating the possibility of the compression member 30 sliding out or vibrating due to centrifugal force, etc.

[0062] The embedding can be implemented in various ways. For example, an interference fit can be used, in which the first end 31 of the compression member 30 is slightly larger than the size of the first limiting groove 110, and the first end 31 of the compression member 30 is pressed into the first limiting groove 110 by applying a certain pressure. A buckle structure can also be used, in which the first end 31 of the compression member 30 is provided with a clamping block, and the first limiting groove 110 is provided with a corresponding clamping groove, and the clamping block is clamped into the clamping groove to achieve embedding.

[0063] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the housing 1001 is provided with a mounting hole 1002, and the handle body 20 is provided with a shaft hole 1003 at a position corresponding to the mounting hole 1002. The handle shaft 10 passes through the mounting hole 1002 and the shaft hole 1003, so that the handle body 20 is rotatably mounted on the housing 1001.

[0064] In this way, the handle body 20 and the housing 1001 can be connected by aligning and passing the handle shaft 10 through the mounting hole 1002 and the shaft hole 1003, without the need for complex alignment or fixing operations. The handle body 20 is rotatably mounted on the housing 1001, so that the handle assembly 100 and the housing 1001 are relatively rotatable, and the handle assembly 100 and the housing 1001 are integrally arranged, thereby reducing the use of materials for manufacturing the energy storage power supply 1000, reducing the management and maintenance cost of materials, and reducing the risk of idle materials.

[0065] Specifically, the diameter of the mounting hole 1002 can be the same as that of the shaft hole 1003, and the mounting hole 1002 can correspond to the position of the shaft hole 1003.

[0066] The depth of the shaft hole 1003 can be adapted to the length of the handle shaft 10 inserted therein. For example, the depth of the shaft hole 1003 can be greater than or equal to half the length of the handle shaft 10, without limitation.

[0067] During assembly, the handle shaft 10 can first pass through the mounting hole 1002 and the shaft hole 1003, so that the handle body 20 is rotatably mounted on the housing 1001. In detail, the handle shaft 10 can first pass through the mounting hole 1002 on the housing 1001, and then the handle shaft 10 is inserted into the shaft hole 1003 of the handle body 20, so that the handle body 20 is rotatably mounted on the housing 1001, thereby realizing the relative rotation between the handle assembly 100 and the housing 1001.

[0068] Please refer to Figure 7In some embodiments, the handle shaft 10 is first inserted through the mounting hole 1002 and then is interference-fitted with the shaft hole 1003, or the handle shaft 10 is first inserted through the shaft hole 1003 and then is interference-fitted with the mounting hole 1002.

[0069] In this way, by interference-fitting the handle shaft 10 with the mounting hole 1002 or the shaft hole 1003, the connection between the handle shaft 10 and the housing 1001 or the handle body 20 can be made more closely and firmly. The friction and mechanical resistance generated by the interference fitting can effectively prevent the handle shaft 10 from loosening or falling off during use, thereby improving the structural stability of the handle assembly 100. Even if a larger vibration or impact is encountered during transportation, the handle assembly 100 can remain stable and ensure its normal function.

[0070] It can be understood that in different energy storage power supplies 1000, due to the differences in size and weight of the handle assembly 100, the force arm of rotation is different, and the damping effect is inconsistent. The embodiments of the present application can make the handle assemblies 100 of different energy storage power supplies 1000 achieve the same damping effect by adjusting the different compression amounts of the compression member 30.

[0071] Please refer to Figure 7 In some embodiments, the handle shaft 10 is first inserted through the mounting hole 1002 and then is interference-fitted with the shaft hole 1003.

[0072] In detail, in one embodiment, the handle shaft 10 includes an abutting portion 13 and a plug-in portion 12. The plug-in portion 12 is interference-fitted with the shaft hole 1003, and the compression member 30 abuts against the abutting portion 13 and generates a reaction force acting on the housing 1001.

[0073] That is, the handle shaft 10 can be interference-fitted with the handle body 20, the handle shaft 10 is clearance-fitted with the housing 1001, and the handle shaft 10 is rotatably connected relative to the housing 1001, at this time the reaction force of the compression member 30 can act on the housing 1001 to generate rotational damping.

[0074] Please refer to Figure 7 In some embodiments, the handle shaft 10 is first inserted through the shaft hole 1003 and then is interference-fitted with the mounting hole 1002.

[0075] In detail, in another embodiment, the handle shaft 10 includes an abutting portion 13 and a plug-in portion 12. The plug-in portion 12 is interference-fitted with the mounting hole 1002, and the compression member 30 abuts against the abutting portion 13 and generates a reaction force acting on the handle body 20.

[0076] That is, the handle shaft 10 can be in clearance fit with the handle body 20, the handle shaft 10 is in interference fit with the shell 1001, and the handle body 20 is rotatably connected to the handle shaft 10, at this time, the reaction force of the compression member 30 can act on the handle body 20 to generate rotary damping.

[0077] In some embodiments, the compression amount of the compression member 30 changes with the size and weight of the handle shaft 10. In this way, the handle assembly 100 of the energy storage power supply 1000 of the present application can achieve different damping effects of damping force by adjusting the compression amount of the compression member 30.

[0078] In addition, since the compression amount of the compression member 30 can be adjusted, the energy storage power supply 1000 of the present application can adjust the damping force of the handle assembly 100 of different weights and sizes to the same, achieving the same damping effect.

[0079] For handle shafts 10 of different sizes, different compression members 30 with different compression amounts can be provided. For example, when the first handle shaft is large in size and heavy in weight, the compression amount of the first compression member sleeved with the first handle shaft can also be set to a large compression amount; when the second handle shaft is small in size and light in weight, the compression amount of the second compression member sleeved with the second handle shaft can also be set to a large compression amount, so that the large handle assembly formed by the first handle shaft and the second compression member and the small handle assembly formed by the second handle shaft and the second compression member can achieve the same damping effect of damping force.

[0080] Please refer to Figure 3 In some embodiments, the abutting portion 13 is provided at one end of the insertion portion 12 and is provided with the first limiting portion 11; the compression member 30 includes a connecting section 32 connecting the first end 31 of the compression member 30; the insertion portion 12 is in interference fit with the shaft hole 1003, the connecting section 32 abuts against the abutting portion 13 and generates a reaction force acting on the shell 1001; or the insertion portion 12 is in interference fit with the mounting hole 1002, the connecting section 32 abuts against the abutting portion 13 and generates a reaction force acting on the handle body 20.

[0081] In this way, the interference fit of the insertion portion 12 with the shaft hole 1003 or the mounting hole 1002 can achieve firm connection of the handle shaft 10 with the handle body 20 or the shell 1001, ensuring the stability of the handle shaft 10 when bearing load. The abutting portion 13 serves as a support point of the compression member 30, and through interaction with the connecting section 32 of the compression member 30, a reaction force is generated to achieve the effect of rotary damping. At the same time, since the abutting portion 13 is provided at one end of the insertion portion 12, the first limiting portion 11 is provided on the abutting portion 13, which is conducive to the machining of the first limiting portion 11.

[0082] Specifically, the connecting section 32 interacts with the abutting portion 13 of the handle shaft 10 to generate a reaction force on the housing 1001 or the handle body 20 during rotation of the handle shaft 10, thereby achieving a rotation damping effect. The compression member 30 can be a one-piece structure, and the connecting section 32 can be a portion of the compression member 30 for abutting with the abutting portion 13.

[0083] Please refer to Figure 7 In some embodiments, the end of the insertion portion 12 of the handle shaft 10 is reserved a preset distance d from the end of the shaft hole 1003 or the mounting hole 1002.

[0084] In this way, by reserving the preset distance d, after the compression member 30 is sleeved on the handle shaft 10 and the handle shaft 10 sleeved with the compression member 30 is assembled with the handle body 20, the handle shaft 10 can be further screwed into the reserved space of the preset distance d, so as to adjust the compression amount of the compression member 30 to be larger.

[0085] Alternatively, after the compression member 30 is sleeved on the handle shaft 10 and the handle shaft 10 sleeved with the compression member 30 is assembled with the handle body 20, the handle shaft 10 can be further screwed out by a certain distance, so as to adjust the compression amount of the compression member 30 to be smaller.

[0086] Alternatively, after the compression member 30 is sleeved on the handle shaft 10 and the handle shaft 10 sleeved with the compression member 30 is assembled with the handle body 20, the handle shaft 10 can be further screwed out by a certain distance, so as to adjust the compression amount of the compression member 30 to be smaller.

[0087] 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 herein. Alternatively, the end of the insertion portion 12 of the handle shaft 10 is reserved a preset distance d from the end of the mounting hole 1002.

[0088] Please refer to Figure 7 and Figure 8 In some embodiments, the housing 1001 is provided with at least one reinforcing rib 1004. The reinforcing rib 1004 is arranged at a contact position of the housing 1001 and the handle shaft 10, and the handle shaft 10 is provided with at least one reinforcing barb 14, which is in gapless or interference fit with the reinforcing rib 1004.

[0089] Specifically, the shell 1001 is provided with at least one reinforcing bone site 1004, and the handle shaft 10 is provided with at least one reinforcing barb 14. That is to say, the shell 1001 can be provided with one reinforcing bone site 1004, or can be provided with a plurality of reinforcing bone sites 1004. The handle shaft 10 can be provided with one reinforcing barb 14, or can be provided with a plurality of reinforcing barbs 14. When the shell 1001 is provided with only one reinforcing bone site 1004, the handle shaft 10 is correspondingly provided with only one reinforcing barb 14, so that one reinforcing bone site 1004 and one reinforcing barb 14 are arranged in cooperation. When the shell 1001 is provided with a plurality of reinforcing bone sites 1004, the handle shaft 10 is correspondingly provided with a plurality of reinforcing barbs 14, so that the plurality of reinforcing bone sites 1004 and the plurality of reinforcing barbs 14 are arranged in cooperation.

[0090] The cooperation mode between the reinforcing barb 14 and the reinforcing bone site 1004 includes two modes of gapless cooperation and interference fit. When the cooperation mode between the reinforcing barb 14 and the reinforcing bone site 1004 is gapless cooperation, the cooperation between the handle shaft 10 and the shell 1001 can be stable. When the cooperation mode between the reinforcing barb 14 and the reinforcing bone site 1004 is interference fit, the cooperation between the handle shaft 10 and the shell 1001 can be more stable. The reinforcing barb 14 can be a reverse triangular shape, or can be other shapes, which are not limited here.

[0091] That is to say, the interference fit between the reinforcing barb 14 of the handle shaft 10 and the reinforcing bone site 1004 of the shell 1001 can solve the problem of the falling of the handle shaft 10 due to failure, and form the second protection of the handle assembly 100.

[0092] Please refer to Figure 7 In some embodiments, the handle body 20 or the shell 1001 is provided with an exhaust groove 101, which is arranged at a position corresponding to the plug-in part 12. The exhaust groove 101 is used to exhaust air in the shaft hole 1003 or the mounting hole 1002 when the plug-in part 12 is inserted into the shaft hole 1003 or the mounting hole 1002.

[0093] In this way, when the handle shaft 10 is inserted into the shaft hole 1003 or the mounting hole 1002 to a certain depth, the air in the shaft hole 1003 or the mounting hole 1002 of the handle body 20 is not easy to be exhausted out of the energy storage power supply 1000, which is easy to cause the air in the energy storage power supply 1000 to be unable to come out, so that compressed air exists in the shaft hole 1003. The compressed air can cause the shaft hole 1003 to have a reverse thrust on the handle shaft 10, which is easy to cause the handle assembly 100 to be bad, and affect the user experience.

[0094] When the insertion part 12 of the handle shaft 10 is inserted into the shaft hole 1003 or the mounting hole 1002 of the handle body 20, the air vent groove 101 provided on the handle body 20 or the shell 1001 can vent the air in the shaft hole 1003 or the mounting hole 1002, thereby avoiding the phenomenon of compressed air existing in the shaft hole 1003 or the mounting hole 1002, avoiding causing the handle assembly 100 to be defective, and affecting the user experience.

[0095] Specifically, each side of the two end portions of the handle body 20 facing each other is provided with a shaft hole 1003. In other embodiments, the shaft hole 1003 can have a taper along a first direction, which is the depth direction of the shaft hole 1003. That is, the diameter of the shaft hole 1003 gradually decreases along the first direction, and the hole wall of the shaft hole 1003 can have a draft angle in the first direction.

[0096] When the handle shaft 10 is interference-fitted with the shaft hole 1003 of the handle body 20, the air vent groove 101 can be provided on the handle body 20. When the handle shaft 10 is interference-fitted with the mounting hole 1002 of the shell 1001, the air vent groove 101 can be provided on the shell 1001.

[0097] In addition, since there may be a small amount of unevenness or sharp protrusions at the two ends of the compression member 30, which directly contact the shell 1001 plastic of the shell 1001, under the interaction of the rotating force and the compression direction force, the compression body has a certain risk of being stuck to the shell 1001 plastic of the shell 1001, causing the handle assembly 100 of the energy storage power supply 1000 to fail in damping. Therefore, by providing the air vent groove 101, the risk of damping failure can be reduced.

[0098] In some embodiments, the handle shaft 10 and the handle body 20 are fixed by cold pressing the shaft through a cold pressing shaft process.

[0099] It can be understood that when the handle shaft 10 and the handle body 20 are fixed as a whole by processes such as sleeving and hot melting, thermal stress is easily generated due to the heating and cooling processes of the handle shaft 10. Thermal stress is stress generated due to the inconsistent thermal expansion or contraction of each part caused by uneven temperature distribution inside the handle shaft 10. When this stress exceeds the strength limit of the handle shaft 10, the handle shaft 10 will crack or be damaged.

[0100] The cold-pressing rotation shaft process generates plastic deformation between the handle rotation shaft 10 and the handle body 20 by applying high pressure, so as to realize cold-pressing fixation. By fixing the handle rotation shaft 10 and the handle body 20 through the cold-pressing rotation shaft process, since the cold-pressing process is performed at room temperature and the handle rotation shaft 10 does not need to be heated, the generation of thermal stress is fundamentally avoided, thereby solving the problem of thermal stress generated by fixing the handle rotation shaft 10 and the handle body 20 through the sleeve plating and hot melting process, and avoiding the cracking of the handle rotation shaft 10.

[0101] Please refer to Figure 3 In some embodiments, the compression member 30 is a spring or a compression spring.

[0102] It can be understood that the damping effect of the handle of the energy storage power supply 1000 in the related art needs to be additionally matched with a damping sheet, and the assembly of the handle of the energy storage power supply 1000 is relatively complex and has a high cost. Therefore, the damping effect realized by the spring or the compression spring can reduce the cost.

[0103] It can be understood that since the damping sheet does not need to be additionally configured, only by compressing the compression member 30, the reaction force generated is associated with the shell 1001 or the handle body 20, and then the reaction force is converted into the damping force required when the shell 1001 and the handle body 20 rotate relative to each other, thereby realizing the damping effect of the handle assembly 100. The assembly of the handle assembly 100 of the energy storage power supply 1000 is simple and has a low cost.

[0104] Specifically, during the rotation of the handle rotation shaft 10, the spring is compressed to generate a reaction force, which acts on the shell 1001 or the handle body 20 to realize the rotation damping effect. Similarly to the spring, the compression spring is compressed during the rotation of the handle rotation shaft 10 to generate a reaction force, which acts on the shell 1001 or the handle body 20 to realize the rotation damping effect.

[0105] Please refer to Figure 3 and Figure 7 In some embodiments, the handle assembly 100 further includes a gasket 40, the gasket 40 including a gasket body 41 and a second limiting portion 42, the gasket body 41 being sleeved on the handle rotation shaft 10, a first side 43 of the gasket body 41 abutting against the compression member 30, a second side 44 of the gasket body 41 abutting against the handle body 20 or the shell 1001, the second limiting portion 42 being arranged on the first side 43 of the gasket body 41, and the second end 33 of the compression member 30 being fixed in the second limiting portion 42.

[0106] In the process of rotating the handle shaft 10, relative sliding between the gasket 40 and the handle shaft 10, the gasket 40 and the compression member 30, and the compression member 30 and the handle shaft 10 can occur, and in the process of relative sliding, the gasket 40 can also vibrate. Therefore, by fixing the second end 33 of the compression member 30 to the second limiting portion 42, the second limiting portion 42 can limit the position of the compression member 30 in the process of rotating the handle shaft 10, so that the gasket 40, the handle shaft 10, the gasket 40, the compression member 30, and the compression member 30 and the handle shaft 10 can rotate together, which can prevent relative sliding between the gasket 40, the handle shaft 10, the gasket 40, the compression member 30, and the compression member 30 and the handle shaft 10, thereby preventing the compression member 30 and the gasket 40 from vibrating, and further preventing the handle assembly 100 from generating noise in the process of use.

[0107] In addition, the gasket 40 is sleeved between the compression member 30 and the shell 1001, which can reduce the damage of the compression member 30 to the plastic of the shell 1001 when the compression member 30 is rotated in use, and prolong the service life of the handle assembly 100.

[0108] Specifically, the shape of the gasket body 41 can be circular, and the size of the gasket body 41 can match the handle shaft 10 and the compression member 30. For example, the inner diameter of the gasket body 41 should be slightly larger than the diameter of the handle shaft 10, and the outer diameter should be slightly smaller than the diameter of the mounting hole 1002 on the handle body 20 or the shell 1001.

[0109] The second limiting portion 42 can be a welding portion, an adhesive portion, or a riveting portion, etc. The compression member 30 can be fixed to the second limiting portion 42 by welding, adhesion, or riveting, etc. For example, the second limiting portion 42 is coated with structural adhesive, and the compression member 30 can be adhered to the second limiting portion 42 by the structural adhesive.

[0110] The second limiting portion 42 can also be a protrusion, a groove, a threaded hole, etc. structure, so as to fix the second end 33 of the compression member 30 to the second limiting portion 42 by clamping or using bolts, screws, etc. fasteners. For example, the second limiting portion 42 is provided with a threaded hole, and the second end 33 of the compression member 30 is correspondingly provided with a threaded hole, and the compression member 30 is fixed to the second limiting portion 42 by using a screw, so that the compression member 30 can rotate together with the handle shaft 10 in the process of rotating the handle shaft 10.

[0111] Please refer to Figure 3 In some embodiments, the second limiting portion 42 includes a plurality of protrusions 420, and a second limiting groove 421 is defined between adjacent two protrusions 420, and the second end 33 of the compression member 30 is embedded in the second limiting groove 421.

[0112] Thus, the second limiting groove 421 can be used to limit the position of the second end 33 of the compression member 30. In addition, embedding the second end 33 of the compression member 30 in the second limiting groove 421 helps to improve the installation accuracy of the compression member 30. During production, the second limiting groove 421 can serve as a reference datum to ensure the correct installation position and direction of the compression member 30. For the gasket 40, the forming block 420 is relatively simple, and thus defining the second limiting groove 421 by the block 420 can reduce manufacturing costs.

[0113] In particular, the second limiting portion 42 can be protruded from the first side 43 of the gasket body 41. The block 420 can be a protruding part on the gasket body 41 for forming the second limiting groove 421 to fix the second end 33 of the compression member 30. The block 420 can be circular, square or other shapes. The number of blocks 420 can be two, three, four or even more. By forming the second limiting groove 421 with the space between adjacent blocks 420, an embedded position is provided for the second end 33 of the compression member 30, ensuring the stable fixation of the compression member 30 during the rotation of the handle shaft 10, thereby eliminating the vibration of the compression member 30.

[0114] Please refer to Figure 3 , Figure 9 and Figure 10 . In some embodiments, the plurality of blocks 420 are arranged at intervals along the circumference of the gasket 40 and are arranged around the handle shaft 10, and at least part of the compression member 30 abuts between the two sides of the handle shaft 10 and the adjacent blocks 420.

[0115] Thus, the plurality of blocks 420 arranged at intervals along the circumference of the gasket 40 provide a plurality of assembly positions for the compression member 30. This allows the compression member 30 to be quickly and accurately installed in any assembly position during production without the need for complex alignment and adjustment. This flexibility greatly improves the efficiency of assembly and reduces production time and cost. The blocks 420 are arranged around the handle shaft 10 and cooperate with the compression member 30 to form a circular ring structure. This structure can uniformly wrap around the compression member 30, providing all-around support and constraint for the compression member 30 during rotation, thereby helping to reduce the distortion of the compression member 30 during rotation.

[0116] Specifically, the second limiting groove 421 is a groove-shaped structure provided on the second limiting portion 42 and formed by two adjacent protrusions 420, and is used for embedding the second end 33 of the compression member 30. The second limiting groove 421 can be a circular groove, a square groove, or the like, and can be adaptively arranged according to the shape of the second end 33 of the compression member 30. The second limiting groove 421 formed by two adjacent protrusions 420 is a through groove, which enables the second limiting groove 421 to adapt to compression members 30 of different lengths. When the handle shaft 10 is rapidly rotated, the second limiting groove 421 can tightly clamp the second end 33 of the compression member 30, thereby preventing the compression member 30 from sliding out or vibrating due to centrifugal force and the like.

[0117] The embedding can be achieved in various ways. For example, an interference fit can be used, so that the second end 33 of the compression member 30 is slightly larger than the size of the second limiting groove 421, and the second end 33 of the compression member 30 is pressed into the second limiting groove 421 by applying a certain pressure. A buckle structure can also be used, in which the second end 33 of the compression member 30 is provided with a clamping block, and the second limiting groove 421 is provided with a corresponding clamping groove, and the clamping block is clamped into the clamping groove to achieve embedding.

[0118] The gasket 40 can be made of plastic. In some embodiments, the gasket 40 is made of polyoxymethylene material.

[0119] It can be understood that, for a handle shaft 10 made of metal material, if the gasket 40 is also made of metal material, the noise generated during rotation of the handle shaft 10 is relatively large, and therefore the gasket 40 made of polyoxymethylene material has relatively small noise. In addition, compared with metal materials, the gasket 40 made of polyoxymethylene material has relatively small cost. In addition, compared with other metal materials, the gasket 40 made of polyoxymethylene material has good wear resistance and relatively low cost.

[0120] The energy storage power supply 1000 of the embodiment of the utility model comprises the handle assembly 100 of any one of the above embodiments.

[0121] Since the energy storage power supply 1000 comprises the handle assembly 100 described above, at least all the beneficial effects of the handle assembly 100 described above are included, and details are not repeated here.

[0122] Please refer to Figure 2 and Figure 4 . Among them, Figure 2 Fig. 1 shows one state of the energy storage power supply 1000 after assembly. Figure 4One state of the energy storage power supply 1000 is shown in the process of assembly. In the process of assembling the energy storage power supply 1000, the handle body 20 of the handle assembly 100 is first sleeved on the shell 1001. Then the first end 31 of the compression member 30 is embedded into the first limiting groove 110 of the handle shaft 10, and the second end 33 of the compression member 30 is embedded into the second limiting groove 421 of the gasket 40. After that, the handle shaft 10 of the assembled compression member 30 and the gasket 40 is inserted through the mounting hole 1002 of the shell 1001 until the handle shaft 10 is inserted into the shaft hole 1003 of the handle body 20. Finally, the handle shaft 10 and the handle body 20 are cold-pressed and fixed together by the cold-pressing shaft process, and the assembly is completed.
