[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0030] In addition, the terms "first", "second" and similar words do not indicate any order, quantity or importance, but are only used to distinguish different technical features. The term "plurality" and similar words mean two or more, unless otherwise expressly limited.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 The battery provided by the embodiment of the present utility model includes a battery body 1 and a shell. The shell includes a bottom plate 21 and a side plate 22 connected to the bottom plate 21. The side plate 22 and the bottom plate 21 form a first accommodating cavity. The top of the shell is provided with an opening 23 opposite to the bottom plate 21. The opening 23 is connected to the first accommodating cavity. The battery body 1 is arranged in the first accommodating cavity, wherein an elastic member is provided between the battery body 1 and the bottom plate 21, and the elastic member is in a compressed state.

[0032] It can be understood that the elastic member is compressed and connected between the battery body 1 and the bottom plate 21 of the shell. When a pulling force is provided to pull the battery body 1 out of the shell along the length direction of the battery body 1, the elastic member can assist in pushing the battery body 1 out, thereby reducing the pulling force to pull the battery body 1 out of the shell along the length direction of the battery body 1.

[0033] In this embodiment, the elastic member can provide a thrust to assist in pulling out the battery body 1 , thereby reducing the pulling force required to pull out the battery body 1 and making it easier to pull out the battery body 1 .

[0034] The technical solution of this application is now described in conjunction with specific embodiments.

[0035] In one embodiment, see Figure 2 、 Figure 3 , the ratio of the elastic force of the elastic member to the weight of the battery body 1 is in the range of 1.5 to 2.

[0036] The ratio of the elastic force of the elastic member to the weight of the battery body 1 can be any one of 1.5, 1.7, 1.9, and 2. The greater the elastic force of the elastic member, the easier it is to remove the battery, further reducing the removal force of the battery.

[0037] It can be understood that when the elastic force of the elastic member is the same, the compression amount of the elastic member is also related to the yield strength of the elastic member. Selecting an elastic member with a smaller yield strength can increase the compression amount of the elastic member, thereby reducing the distance between the battery body 1 and the bottom plate 21 of the shell, thereby making the overall size of the battery along the length direction smaller and improving the portability of the battery.

[0038] It should be noted that when the ratio of the elastic force of the elastic part to the weight of the battery body 1 is greater than 2, the battery body 1 is pushed too hard by the elastic part and is prone to falling off. When the ratio of the elastic force of the elastic part to the weight of the battery body 1 is less than 1.5, the battery body 1 is pushed too hard by the elastic part and the effect of the elastic part in assisting the battery removal is not obvious.

[0039] In this embodiment, by limiting the range of the ratio of the elastic force of the elastic member to the weight of the battery body 1 , the battery body 1 can be prevented from falling off while further improving the effect of the elastic member in assisting the battery removal.

[0040] In one embodiment, see Figure 6 The bottom plate 21 of the shell is provided with an ejection hole 24 , one end of the elastic member abuts against the ejection hole 24 , and the other end of the elastic member abuts against the battery body 1 .

[0041] The battery body 1 is further provided with an ejection portion 13 on one side of the surface facing the bottom plate 21 , which is matched with the ejection hole 24 .

[0042] One end of the elastic member is fixedly connected to the ejection portion 13 , and the other end of the elastic member is located in the ejection hole 24 .

[0043] The ejection hole 24 may be a circular hole, and the size of the elastic member is smaller than that of the circular hole, so that the elastic member can be accommodated in the circular hole after being compressed.

[0044] The ejection portion 13 may be a cylindrical structure. The size of the ejection portion 13 is smaller than the size of the ejection hole 24 , and the ejection portion 13 may be partially accommodated in the ejection hole 24 .

[0045] It is understandable that the ejection hole 24 can limit the elastic member, preventing the end of the elastic member that abuts the bottom of the shell from deviating, resulting in the failure of the elastic member to assist the battery body 1 in ejecting.

[0046] In this embodiment, an ejection hole 24 for limiting the elastic member is provided on the bottom plate 21 of the housing, so that the elastic member is not easily deflected when under pressure, thereby improving the yield rate of the elastic member assisting the ejection of the battery body 1.

[0047] In one embodiment, the elastic member is a linear spring.

[0048] The linear spring refers to a spring in which the relationship between the compression amount of the elastic member and the elastic force of the elastic member changes linearly.

[0049] It is understandable that the linear spring is more conducive to regulating the elastic force of the elastic member so that the elastic force of the elastic member can satisfy a ratio of the elastic force to the weight of the battery body 1 within a range of 1.5 to 2.

[0050] In one embodiment, see Figure 3 A groove is provided on the outer side surface of the battery body 1 along the circumference of the battery body 1, and a gap is formed between the outer side surface of the battery body 1 and the inner side surface of the side plate 22 of the shell; wherein a waterproof ring 4 is provided in the groove, and the waterproof ring 4 seals the gap.

[0051] The waterproof ring 4 surrounds the outer side surface of the battery body 1 along the circumferential direction.

[0052] The outline of the battery body 1 can be any one of a cuboid, a cube or a cylinder.

[0053] The circumference of the battery body 1 refers to a circle perpendicular to the length direction of the battery body 1 .

[0054] The waterproof ring 4 is made of elastic material or buffer material. During the squeezing process between the outer side surface of the battery body 1 and the inner side surface of the side plate 22 of the shell, the waterproof ring 4 seals the gap.

[0055] It is understandable that partially setting the waterproof ring 4 in the groove can fix the waterproof ring 4 and prevent the waterproof ring 4 from being abnormally offset during the relative movement of the battery body 1 and the shell, resulting in waterproof failure.

[0056] It should be noted that the gap between the battery body 1 and the shell is easily invaded by water vapor. This gap is inevitably generated during the assembly process. By providing at least one circle of waterproof ring 4 on the outer side of the battery body 1, the channel for water vapor to invade through the gap can be cut off, preventing water vapor from invading the interior of the battery.

[0057] In this embodiment, the waterproof ring 4 is provided to seal the gap that is easily invaded by water vapor, thereby preventing the battery from being invaded by water vapor and becoming ineffective.

[0058] In one embodiment, see Figure 3 The waterproof ring 4 is arranged close to the side of the battery body 1 away from the bottom plate 21 of the shell.

[0059] In one embodiment, the waterproof ring 4 may include a plurality of sub-waterproof portions arranged along the length direction of the battery body 1 .

[0060] The outer side surface of the battery body 1 may be provided with multiple circles of grooves, and the grooves are provided in a one-to-one correspondence with the sub-waterproof parts.

[0061] It is understandable that by providing multiple circles of waterproof parts, the waterproof effect can be enhanced. When any sub-waterproof part fails, the other sub-waterproof parts can play a waterproof role and prevent water vapor from invading the inside of the battery along the gap.

[0062] In this embodiment, by providing multiple circles of waterproof parts along the length direction of the battery body 1, the waterproof effect can be enhanced.

[0063] In one embodiment, the waterproof ring 4 includes a first part located in the groove and a second part protruding from the outer side surface of the battery body 1; in the direction from the center of the battery body to the outer side surface of the battery body, the thickness of the second part in a natural state is d1, and the width of the gap is d2, wherein, when the second part of the waterproof ring is accommodated in the gap, the compression rate of the waterproof ring in the direction from the center of the battery body to the outer side surface of the battery body is S, S = (d1-d2) / d1, and the value range of S is 15% to 25%.

[0064] The value of S may be any one of 15%, 20%, and 25%.

[0065] Wherein, d1>d2 and the difference between d1 and d2 ranges from 0.2 mm to 0.5 mm.

[0066] Wherein, d1>d2 and the difference between d1 and d2 can be any one of 0.2 mm, 0.3 mm, 0.4 mm, and 0.5 mm.

[0067] The natural state in the present application refers to the normal state of the waterproof ring 4 when it is not subject to external forces.

[0068] It is understandable that by setting the thickness of the second portion protruding from the outer side of the battery body 1 to be larger, the second portion will be deformed during the squeezing process by the side plate 22 of the shell, and the squeezed waterproof ring 4 will have a better sealing effect.

[0069] It should be noted that when d1>d2 and the difference between d1 and d2 is less than 0.2 mm, the extrusion of the waterproof ring 4 is not obvious, resulting in poor sealing effect. When d1>d2 and the difference between d1 and d2 is greater than 0.5 mm, the static friction force formed by the extrusion between the waterproof ring 4 and the side plate 22 of the shell is too large, which will cause the extraction force of the battery body 1 to increase, which is not conducive to the extraction of the battery.

[0070] In this embodiment, by ensuring that the difference between the thickness of the second portion of the waterproof ring 4 extending beyond the groove and the gap is within a range of 0.2 mm to 0.5 mm, on the one hand, the waterproof ring 4 is squeezed to enhance the sealing and waterproofing effect, and on the other hand, the static friction between the waterproof ring 4 and the side plate 22 of the outer shell is small, which is conducive to the battery body 1 being ejected from the outer shell.

[0071] In one embodiment, along the length direction of the battery body 1, the length of the groove is d3, and the length of the waterproof ring 4 in the natural state is d4, wherein d3>d4 and the difference between d3 and d4 ranges from 0.05 mm to 0.2 mm.

[0072] Wherein, d3>d4 and the difference between d3 and d4 can be 0.05 mm, 0.1 mm, or 0.2 mm.

[0073] It is understandable that, since the waterproof ring 4 will be compressed along the circumferential direction, it is necessary to reserve some space for the groove relative to the waterproof ring 4 along the length direction of the battery body 1 so that the squeezed waterproof ring 4 can be accommodated by the groove.

[0074] It should be noted that when d3>d4 and the difference between d3 and d4 is less than 0.05 mm, the space reserved for the waterproof ring 4 is too small, and along the length direction of the battery body 1, it is not enough to accommodate the squeezed waterproof ring 4. When d3>d4 and the difference between d3 and d4 is greater than 0.2 mm, the waterproof ring 4 is easy to fall off from the groove, resulting in poor sealing effect of the waterproof ring 4.

[0075] In this embodiment, along the length direction of the battery body 1, by making the difference between the length of the groove and the length of the waterproof ring 4 range from 0.05 mm to 0.2 mm, on the one hand, it is beneficial for the groove to better accommodate the waterproof ring 4 after being squeezed, and on the other hand, it can also prevent the waterproof ring 4 from falling off from the groove, thereby improving the sealing effect of the waterproof ring 4.

[0076] In one embodiment, see Figure 4 、 Figure 5 A card slot 26 is provided at the edge of the shell near the opening 23, and the battery body 1 is provided with a boss 15. The card slot 26 is engaged with the boss 15, and the card slot 26 of the shell and the boss 15 of the battery body 1 are interference fitted.

[0077] It can be understood that along the length direction of the battery body 1, the battery body 1 is subjected to the thrust of the elastic member, and is also subjected to the static friction between the waterproof ring 4 and the side plate 22 of the outer shell. When the thrust of the elastic member is greater than the static friction between the waterproof ring 4 and the side plate 22 of the outer shell, the slot 26 and the boss 15 prevent the battery body 1 from being pushed out by the elastic member and falling off.

[0078] In this embodiment, the battery body 1 and the housing are engaged with each other through the slot 26 and the boss 15 , and the slot 26 and the boss 15 are interference fit, which can further prevent the battery from falling off.

[0079] In one embodiment, a handle is provided at one end of the battery body 1 away from the bottom plate 21 of the housing.

[0080] When the battery body 1 needs to be removed from the housing, the handle needs to be manually pulled to provide a pulling force along the length direction of the battery body 1, so that the engagement between the slot 26 and the boss 15 is invalidated, and the battery body 1 is ejected using the pushing force of the elastic member.

[0081] In one embodiment, the elastic member in any of the above embodiments may be a spring.

[0082] There is at least one elastic member, and specifically, there can be two elastic members, and the two elastic members are evenly arranged between the battery body 1 and the bottom plate 21 of the shell.

[0083] Wherein, the two elastic members are symmetrically arranged.

[0084] In one embodiment, the battery body 1 includes an upper cover 11 and a lower cover 12 . The upper cover 11 and the lower cover 12 are connected to each other to form a second accommodating cavity. At least one electrode assembly is disposed in the second accommodating cavity.

[0085] The electrode assembly includes a first electrode plate, a second electrode plate, and a diaphragm located between the first electrode plate and the second electrode plate.

[0086] In one embodiment, the upper cover 11 is further provided with a charging and discharging port 7 and a Type-C charging port, and the battery further includes an adapter plate 5 , which is connected to the charging and discharging port 7 .

[0087] Among them, the Type-C charging port is used to achieve mobile charging and discharging.

[0088] In one embodiment, see Figure 3 、 Figure 6 The inner side of the bottom plate 21 of the shell is also provided with an anti-fool column 25, and the side surface of the upper cover 11 facing the bottom plate 21 is also provided with an anti-fool hole 14, and the anti-fool column 25 is assembled and matched with the anti-fool hole 14.

[0089] Among them, the anti-fool column 25 and the anti-fool hole 14 are engaged with each other to achieve the effect of anti-fool fixing.

[0090] In one embodiment, a light sticker 6 and a light strip are further provided on the surface of the upper cover 11 facing the bottom plate 21 , and the light sticker 6 covers the light strip.

[0091] Among them, the light bar is used to display functions, for example: the light bar can display the battery power.

[0092] The light sticker 6 is used to cover the light bar, protecting the light bar below from damage by external forces, and at the same time preventing water vapor from invading the light bar below.

[0093] The light bar may include LED lights.
