[0033] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] This embodiment provides a portable energy storage device, which includes an energy storage module and at least two handle assemblies. The handle assemblies are rotatably mounted on the outer wall of the energy storage module so that the user can lift the energy storage module.

[0036] like Figures 1-7 As shown, the handle assembly includes a handle housing 3, a soft rubber part 1, and an adhesive sheet 2. The handle housing 3 includes a crossbar 31 and two connecting parts 32 respectively connected to both ends of the crossbar 31. The crossbar 31 and the two connecting parts 32 together form a U-shaped structure. The adhesive sheet 2 is installed on the inside of the crossbar 31 of the handle housing 3. The soft rubber part 1 and the adhesive sheet 2 are bonded together with 3M adhesive or glue.

[0037] Furthermore, such as Figure 2 , Figures 4-7 As shown, the handle housing 3 is set as a hollow structure, and the inner side of the handle housing 3 is provided with multiple hollow grooves 34. The soft rubber part 1 is provided with a connecting cavity 11 for accommodating the adhesive piece 2. The inner wall of the connecting cavity 11 is provided with a first adhesive structure, and the side of the adhesive piece 2 away from the handle housing 3 is provided with a second adhesive structure. The first adhesive structure and the second adhesive structure are bonded together by adhesive.

[0038] The bottom is provided with a first bonding surface 12, the side of the adhesive sheet 2 away from the handle shell 3 is provided with a second bonding surface 21, the first bonding surface 12 and the second bonding surface 21 are bonded by adhesive, and the first bonding surface 12 and the second bonding surface 21 are provided as mutually adapted arc surface structures.

[0039] Specifically, the portable handle assembly provided by the embodiment is provided with the soft glue piece 1 for the user to hold when lifting the portable energy storage device, and the soft glue piece 1 provides a good grip. The adhesive sheet 2 is arranged between the soft glue piece 1 and the handle shell 3, and the soft glue piece 1 is bonded to the adhesive sheet 2 through the bonding between the first bonding structure and the second bonding structure, so as to indirectly connect the soft glue piece 1 and the handle shell 3. The arrangement of the adhesive sheet 2 not only avoids the integral molding of the second bonding structure and the handle shell 3, simplifies the mold complexity, but also is more conducive to controlling the structure and size of the second bonding surface 21 during molding, and also makes the soft glue piece 1 and the adhesive sheet 2 have sufficient bonding area. On the premise of ensuring bonding reliability, on the one hand, the handle shell 3 is provided as a hollow structure, which reduces the material cost of the handle shell 3, reduces the weight of the handle shell 3 and the overall weight of the portable handle assembly, thereby reducing the overall weight of the portable energy storage device and improving portability. On the other hand, the connection cavity 11 is arranged in the soft glue piece 1, and the material cost of the hollow structure is also reduced compared with the thicker solid structure, so the overall cost of the portable handle assembly is reduced.

[0040] For example, the first bonding structure includes the first bonding surface 12, and the second bonding structure includes the second bonding surface 21. The first bonding surface 12 and the second bonding surface 21 are provided as mutually adapted arc surface structures. Since the first bonding surface 12 and the second bonding surface 21 are provided as mutually adapted arc surface structures or corrugated surface structures, the contact area and the stress area of the bonding between the soft glue piece 1 and the adhesive sheet 2 are increased, and the fit is improved, so that the bonding firmness is significantly improved. Also, the use of exposed screws to directly lock the soft glue piece 1 to the handle shell 3 is avoided, and the appearance consistency is ensured.

[0041] In other embodiments, the first bonding surface 12 and the second bonding surface 21 can be provided as mutually adapted corrugated surface structures. The corrugated surface structure refers to a surface structure with a wave shape or a snake shape in the longitudinal or transverse cross section. Compared with the arc surface structure, the corrugated surface structure has a larger surface area, can accommodate more and more uniform adhesive, and has higher bonding reliability.

[0042] In the embodiment, as shown in Figures 4-7 The first bonding structure further includes a third bonding surface 13, and the second bonding structure further includes a fourth bonding surface 22. The third bonding surface 13 is arranged at the bottom of the connection cavity 11, and the third bonding surface 13 and the fourth bonding surface 22 are bonded by adhesive. The third bonding surface 13 and the fourth bonding surface 22 are both provided as planar structures, so as to facilitate molding control and reduce production difficulty.

[0043] Exemplarily, the soft glue piece 1 and the adhesive sheet 2 are both provided in a strip structure, and two first adhesive surfaces 12 and two second adhesive surfaces 21 are respectively arranged correspondingly, the two first adhesive surfaces 12 are distributed on the left and right sides of the third adhesive surface 13 in the length direction, and the two second adhesive surfaces 21 are distributed on the left and right sides of the fourth adhesive surface 22 in the length direction. During the glue coating, the planar structure of the third adhesive surface 13 and the fourth adhesive surface 22 is beneficial to the accumulation of the adhesive, and the overflow part can also overflow to the first adhesive surfaces 12 and the second adhesive surfaces 21 on both sides, so as to increase the actual amount of glue used, and further improve the adhesive effect.

[0044] Of course, the adhesive sheet 2 and the connecting cavity 11 are both provided with vertical side wall structures, and the side wall structures of the two can also be bonded by adhesive, so as to further increase the bonding area and improve the bonding reliability.

[0045] Exemplarily, as shown in Figure 3 , the outer surface of the soft glue piece 1 is provided with a plurality of second grooves 14, the second grooves 14 are arranged along the width direction of the soft glue piece 1, and the plurality of second grooves 14 are arranged at intervals along the length direction of the soft glue piece 1. Specifically, the arrangement of the second grooves 14 can increase the friction when the user holds it, and play a role of anti-skid.

[0046] Exemplarily, the adhesive sheet 2 is made of plastic. Specifically, the adhesive sheet 2 is made by injection molding.

[0047] Exemplarily, the soft glue piece 1 is made of silicone material. Of course, in other embodiments, the soft glue piece 1 can also be made of other soft materials such as rubber.

[0048] Exemplarily, the side of the adhesive sheet 2 facing the soft glue piece 1 is provided with a first groove 23, the first groove 23 is arranged in the second adhesive surface 21, and the first groove 23 can accommodate adhesive. Further, the first groove 23 is provided with a plurality of first grooves 23, the first grooves 23 are arranged along the width direction of the adhesive sheet 2, and the plurality of first grooves 23 are arranged at intervals along the length direction of the adhesive sheet 2.

[0049] The arrangement of the first groove 23 has two aspects: first, during the bonding operation, the first groove 23 can store adhesive to increase the actual amount of glue used and improve the bonding effect between the soft glue piece 1 and the adhesive sheet 2; on the other hand, during the injection molding of the adhesive sheet 2, the protrusion corresponding to the first groove 23 on the injection mold reduces the flow rate of the molten glue, so that the air in the mold has enough time to escape, greatly reducing the amount of residual air in the mold and improving the yield of the adhesive sheet 2.

[0050] Exemplarily, as shown in Figure 2 and Figure 5As shown, the adhesive sheet 2 is provided with two connecting through holes 24, and the inner side of the handle shell 3 is correspondingly provided with two threaded holes, and two fastening screws 4 are respectively screwed through the corresponding connecting through holes 24 and threaded holes to be connected with the handle shell 3, and the soft rubber piece 1 is covered on the fastening screws 4 and the connecting through holes 24. On the one hand, the threaded connection ensures the installation reliability between the adhesive sheet 2 and the handle shell 3, and on the other hand, the soft rubber piece 1 shields the fastening screws 4 and the connecting through holes 24, so that the user has a better grip feeling when holding, and the appearance consistency is not affected.

[0051] For example, the bottom of the adhesive sheet 2 is provided with an installation step 25 extending along the circumference thereof, the upper end of the installation step 25 carries and limits the bottom of the soft rubber piece 1, and the lower end of the installation step 25 is pressed against the hand-held handle during installation. The installation step 25 plays a role of installation and limiting, and can also block the adhesive in the connecting cavity 11 from overflowing.

[0052] For example, the handle shell 3 is made of plastic. Specifically, the handle shell 3 is made by injection molding. Since the handle shell 3 is provided in a hollow structure, the wall thickness of the handle shell 3 is greatly reduced, and the wall thickness of the handle shell 3 is more uniform, thereby eliminating problems such as shrinkage and excessive holding time caused by excessive wall thickness during molding.

[0053] Embodiment Two:

[0054] As shown in the embodiment one, on the basis of the embodiment one, another hand-held handle assembly is provided, which is different from the embodiment one in that: Figure 8 The bottom of the connecting cavity 11 is only provided with a first adhesive surface 12, and the connecting cavity 11 is not provided with a third adhesive surface 13, and the first adhesive surface 12 is provided as an arc surface structure penetrating through the bottom of the connecting cavity 11. Correspondingly, the side of the adhesive sheet 2 away from the handle shell 3 is also only provided with a second adhesive surface 21, and the adhesive sheet 2 is not provided with a fourth adhesive surface 22, and the second adhesive surface 21 is also provided as an arc surface structure penetrating through the top surface of the adhesive sheet 2. This setting simplifies the molding die, and also has the effect of increasing the stress area and adhesive area between the soft rubber piece 1 and the adhesive sheet 2, improving the fitting degree, thereby significantly improving the adhesive effect.
