[0001] The utility model relates to the technical field of batteries, in particular to a battery handle structure and a battery. Background Art

[0002] To facilitate the grabbing of the battery, the battery is usually provided with a handle. In the prior art, there are two main types of battery handle structures for Ebike (Electric Bicycle) in the industry:

[0003] The first type is a non-hidden fixed handle on the battery casing. The handle is fixed in a fixed position and cannot be moved. It has certain disadvantages: the handle usually needs to be higher than the battery body, which takes up extra space; the handle is easily damaged during battery use (falling), thereby damaging the battery casing and posing a safety hazard to the battery.

[0004] The second type is to install a hidden handle without rotation limit on the outside of the battery shell, which also has shortcomings: the handle has no rotation limit, the handle state is uncontrollable and easy to be damaged, the user experience is not good, and there are safety hazards. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the present invention is to provide a battery handle structure and a battery to solve the problems in the above background technology that the handle requires additional space and the handle state is uncontrollable and easy to be damaged.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is a battery handle structure, comprising:

[0007] The end cover comprises a connecting portion and a receiving portion, wherein the connecting portion is protruding along a first direction and the receiving portion is arranged on the outer side of the connecting portion.

[0008] The handle is provided on the side of the end cover where the connecting portion is provided along the first direction, and is movably connected to the connecting portion at both ends along the second direction, so as to enable the handle to rotate circumferentially relative to the end cover and switch between a locked state and an open state. The first direction is perpendicular to the second direction, and the circumference surrounds the second direction.

[0009] The locked state includes the handle being in contact with the receiving portion.

[0010] The open state includes the handle being separated from the receiving portion.

[0011] A push pin assembly is used to attach the handle to the receiving portion when in the locked state.

[0012] The battery handle structure provided by this utility model features an end cap that can be used as the top cover of the battery. The handle is rotatably connected to the end cap, rather than being integrally formed with the battery housing, eliminating any impact on the housing. Furthermore, when locked, the handle and top cover are secured together via a push pin, making the handle's position controllable and eliminating the need for additional space for the handle, thus improving the user experience.

[0013] In some embodiments, the end cover further includes a step portion, which is provided at a connection between the connecting portion and the receiving portion along the second direction, and is configured to abut against the handle to limit position in the open state.

[0014] By adopting the above technical solution, when in the open state, the handle is separated from the receiving part and can rotate circumferentially. After abutting against the handle, the position of the handle is perpendicular to the end cover, which is convenient for users to grab and improve the user experience.

[0015] In some embodiments, the handle includes a driving portion, a first movable portion, and a second movable portion. The driving portion is disposed above the connecting portion, and the first movable portion and the second movable portion are disposed at opposite ends of the connecting portion along the second direction, respectively, and both extend along a third direction. Connecting assemblies are symmetrically disposed at the bottoms of the first movable portion and the second movable portion, and are connected to the connecting portion, with the first direction, the second direction, and the third direction being perpendicular to each other.

[0016] By adopting the above technical solution, the handle can be switched between the locked state and the open state by rotating the driving part. In the locked state, the driving part, the first movable part and the second movable part are all attached to the receiving part.

[0017] In some embodiments, the ejector assembly includes an ejector post. The ejector post extends in a third direction and has a telescopic ball head disposed on its top. The telescopic ball head is capable of elastically extending and retracting in the third direction. The top of the connecting portion is provided with an ejector pin holder for plugging and securing the ejector post.

[0018] The ejector pin assembly further includes an ejector pin mating groove and an abutment block. The ejector pin mating groove is provided at the bottom of the driving portion and extends along the first direction, and is configured to slidably engage with the telescopic ball head when the handle rotates. The abutment block is provided on the side of the driving portion facing the connecting portion and is disposed in correspondence with the ejector pin mating groove to close the ejector pin mating groove.

[0019] By adopting the above technical solution, in the locked state, the telescopic ball head is placed in the ejector pin matching groove and abuts against the abutment block to limit the position, thereby fixing the handle to the end cover.

[0020] In some embodiments, the connecting assembly includes a nut and a torsion spring. A nut compartment and a torsion spring positioning hole are provided on both sides of the connecting portion along the second direction. The nut compartment is provided near the step portion and is configured to be plugged and fixed with the nut. The torsion spring includes a positioning post and a limiting post. The positioning post is provided at the end of the torsion spring and extends along the third direction, configured to be plugged and fixed with the torsion spring positioning hole. The limiting post is provided at the rear end of the torsion spring and extends along the first direction.

[0021] Using the above technical solution, the torsion spring is a coil spring, and the positioning column at the end of the torsion spring is fixed to the connecting part. When the handle rotates circumferentially, the torsion spring generates a rotational force, which can pull the handle back to the initial position. The initial position is that the handle abuts against the step part to limit the position.

[0022] In some embodiments, the connecting assembly further comprises a torsion spring compartment, a bolt head compartment, a bolt, and a mounting through-hole. The torsion spring compartment is disposed on the side of the connecting assembly facing the drive portion along the second direction, and the torsion spring is disposed within the torsion spring compartment. The bolt head compartment is disposed on the other side of the connecting assembly along the second direction. The mounting through-hole extends along the second direction and connects the torsion spring compartment and the bolt head compartment, allowing the bolt to pass through the torsion spring compartment, the mounting through-hole, the bolt head compartment, and the torsion spring along the second direction to threadably connect to the nut.

[0023] In some embodiments, the torsion spring magazine is provided with a limiting groove, which is used to correspond to the position of the limiting column and be clamped and fixed when the handle abuts against the step portion.

[0024] By adopting the above technical solution, when the handle is in the initial position, the limiting groove corresponds to the position of the limiting column and is fixedly engaged, so that the torsion spring can return to the initial position after rotating with the handle.

[0025] In some embodiments, the driving unit further includes an anti-slip strip, which is provided on the top of the driving unit.

[0026] By adopting the above technical solution and providing an anti-slip strip, the user can be prevented from sliding when grasping, thereby improving the user experience.

[0027] In some embodiments, another technical solution employed by the present invention is a battery comprising a battery body, a housing, and a battery handle structure as described in the various embodiments above. The battery body is disposed within the housing, which extends along a first direction and has an opening at one end. The end cap of the battery handle structure is sealed to the opening, and the handle is disposed away from the battery body along the first direction.

[0028] By adopting the above technical solution, after the battery handle is provided, the battery can be grabbed by holding the battery handle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0036] refer to Figures 1 to 4 , Figure 1 A three-dimensional diagram of a battery handle structure 1 and a battery provided by an embodiment of the present invention is shown, wherein the handle 3 is in an open state; Figure 2 A perspective view of a battery handle structure 1 and a battery mid-handle 3 provided in an embodiment of the present utility model is shown; Figure 3 The structure diagram of a battery handle structure 1 and a battery provided by an embodiment of the utility model is shown. Figure 1 , wherein the state of the handle 3 is the open state; Figure 4 The structure diagram of a battery handle structure 1 and a battery provided by an embodiment of the utility model is shown. Figure 2 , wherein the state of the handle 3 is a locked state.

[0037] like Figures 1 to 4 As shown, the technical solution provided by this application is a battery handle structure 1, including an end cover 2, a handle 3 and a top pin assembly, wherein the end cover 2 includes a connecting portion 20 and a receiving portion 21. The connecting portion 20 is along a first direction ( Figure 1 The receiving portion 21 is provided on the outside of the connecting portion 20. The handle 3 is provided on the side of the end cover 2 where the connecting portion 20 is provided along the first direction, and is provided along the second direction ( Figure 1 The two ends of the handle 3 are movably connected to the connecting portion 20, so as to make the handle 3 relative to the end cover 2 along the circumferential direction ( Figure 1 The handle 3 rotates (indicated by the θ direction) and switches between a locked state and an open state. The first direction is perpendicular to the second direction and circumferentially surrounds the second direction. The locked state includes the handle 3 abutting against the receiving portion 21, while the open state includes the handle 3 separating from the receiving portion 21. The ejector pin assembly is used to attach the handle 3 to the receiving portion 21 in the locked state.

[0038] In the battery handle structure 1 provided herein, the end cap 2 can be used as the top cover of the battery. The handle 3 is rotatably connected to the end cap 2, rather than being integrally formed with the battery housing 60, thereby eliminating any interference with the housing 60. Furthermore, when locked, the handle 3 and the top cover are fixed together as a whole via a push pin, making the position of the handle 3 controllable and eliminating the need for additional space for the handle 3, thereby improving the user experience.

[0039] In some embodiments, reference Figures 1 to 4 The end cover 2 further includes a step portion 22. The step portion 22 is provided at the connection between the connecting portion 20 and the receiving portion 21 along the second direction, and is used to abut against the handle 3 to limit position when in the open state.

[0040] For example, in the open state, the handle 3 is separated from the receiving portion 21 and can rotate circumferentially. After abutting against the handle 3, the position of the handle 3 is perpendicular to the end cover 2, which is convenient for the user to grab and improve the user experience.

[0041] In some embodiments, reference Figures 1 to 4 In this embodiment, the handle structure is described in the locked state (eg Figure 1 As shown), the handle 3 includes a driving portion 30, a first movable portion 31 and a second movable portion 32. The driving portion 30 is provided above the connecting portion 20, and the first movable portion 31 and the second movable portion 32 are respectively provided at both ends of the connecting portion 20 along the second direction, and both move along the third direction ( Figure 1The bottom of the first movable portion 31 and the bottom of the second movable portion 32 are symmetrically provided with connecting components 5, which are connected to the connecting portion 20. The first direction, the second direction, and the third direction are perpendicular to each other.

[0042] For example, the handle 3 can be switched between the locked state and the open state by rotating the driving portion 30. In the locked state, the driving portion 30, the first movable portion 31 and the second movable portion 32 are all attached to the receiving portion 21.

[0043] In some embodiments, reference Figures 1 to 4 The ejector assembly includes an ejector post 40. The ejector post 40 extends in a third direction and is provided with a telescopic ball head 41 at its top. The telescopic ball head 41 is capable of elastically extending and retracting in the third direction. The top of the connecting portion 20 is provided with an ejector pin hopper 33 for plugging and securing the ejector post 40.

[0044] The ejector pin assembly also includes an ejector pin engaging groove 42 and an abutment block 43. The ejector pin engaging groove 42 is located at the bottom of the drive portion 30 and extends in a first direction, slidably engaging with the telescopic ball 41 when the handle 3 rotates. The abutment block 43 is located on the side of the drive portion 30 facing the connecting portion 20 and corresponds to the ejector pin engaging groove 42, thereby closing the ejector pin engaging groove 42.

[0045] For example, in the locked state, the telescopic ball head 41 is positioned within the ejector pin fitting groove 42 and abuts against the abutment block 43 to secure the handle 3 to the end cap 2. When switching from the locked state to the open state, the telescopic ball head 41 contacts and presses downward against the abutment block 43. After the abutment block 43 completely passes through the telescopic ball head 41, the handle 3 is in the open state, and the telescopic ball head 41 elastically recovers. When switching from the open state to the locked state, the telescopic ball head 41 contacts and presses downward against the abutment block 43. After the abutment block 43 completely passes through the telescopic ball head 41, the telescopic ball head 41 elastically recovers and abuts against the abutment block 43 to secure the handle 3. The handle 3 is in the locked state.

[0046] In some embodiments, reference Figures 1 to 4 The connecting assembly 5 includes a nut 50 and a torsion spring 51. Nut compartments 23 and torsion spring positioning holes 24 are provided on both sides of the connecting portion 20 along the second direction. The nut compartments 23 are located near the step 22 and are used for plugging and fixing with the nut 50. The torsion spring 51 includes a positioning post 52 and a limiting post 53. The positioning post 52 is provided at the end of the torsion spring 51 and extends along the third direction, and is used for plugging and fixing with the torsion spring positioning hole 24. The limiting post 53 is provided at the tail end of the torsion spring 51 and extends along the first direction.

[0047] Exemplarily, the torsion spring 51 is a coil spring, and the positioning column 52 at the end of the torsion spring 51 is fixed to the connecting portion 20. When the handle 3 rotates in the circumferential direction, the torsion spring 51 generates a rotational force, which can pull the handle 3 back to the initial position. The initial position is that the handle 3 is in contact with the step portion 22 and is limited. When switching from the locked state to the open state, the rotational force generated by the torsion spring 51 can quickly pull the handle 3 back to the initial position, which is convenient for the user to grab and improve the user experience.

[0048] In some embodiments, reference Figures 1 to 4 The connecting assembly 5 further includes a torsion spring compartment 54, a bolt head compartment 55, a bolt 56, and a mounting through-hole 57. The torsion spring compartment 54 is located on the side of the connecting assembly 5 facing the driving unit 30 along the second direction, and the torsion spring 51 is disposed within the torsion spring compartment 54. The bolt head compartment 55 is located on the other side of the connecting assembly 5 along the second direction. The mounting through-hole 57 extends along the second direction and connects the torsion spring compartment 54 and the bolt head compartment 55, allowing the bolt 56 to pass through the torsion spring compartment 54, the mounting through-hole 57, the bolt head compartment 55, and the torsion spring 51 in the second direction and be threadedly connected to the nut 50.

[0049] In some embodiments, reference Figures 1 to 4 The torsion spring bin 54 is provided with a limiting groove 58 for corresponding to the position of the limiting column 53 and being fixed when the handle 3 abuts against the step portion 22.

[0050] For example, when the handle 3 is in the initial position, the limiting groove 58 corresponds to the limiting column 53 and is fixedly engaged therewith, so that the torsion spring 51 can return to the initial position after rotating with the handle 3 .

[0051] In some embodiments, reference Figures 1 to 4 The driving unit 30 further includes an anti-slip strip 34 . The anti-slip strip 34 is provided on the top of the driving unit 30 .

[0052] For example, by providing the anti-slip strip 34 , the user can be prevented from sliding when grasping, thereby improving the user experience.

[0053] In some embodiments, reference Figures 1 to 4 Another technical solution provided by this application is a battery comprising a battery body, a housing 60, and a battery handle structure 1 as described in the aforementioned embodiments. The battery body is disposed within the housing 60, which extends along a first direction and has an opening at one end. The end cap 2 of the battery handle structure 1 is sealedly connected to the opening, and the handle 3 is disposed away from the battery body along the first direction.

[0054] For example, after the battery handle 3 is provided, the battery can be grabbed by holding the battery handle 3. For example, when the battery is used in an electric bicycle and needs to be replaced, the battery needs to be exposed and then the battery can be removed from the electric bicycle by holding the handle 3, thereby improving the user experience.

[0055] The above implementation methods are only for illustrating the technical concept and features of the utility model. Its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the scope of protection of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the scope of protection of the utility model.
