Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to a battery. Background Technology

[0002] With the development of battery technology, portable batteries are being used more and more widely, and their capacity is becoming larger and larger. As a result, their weight is also increasing, which makes it more inconvenient to carry portable batteries. Therefore, portable batteries with handles have begun to appear.

[0003] Portable batteries typically operate in both horizontal and vertical positions, and a single handle is insufficient for handling them in both configurations. Therefore, portable batteries are usually equipped with two handles on adjacent surfaces of the casing, allowing for the selection of the appropriate handle based on the battery's operating position.

[0004] However, adding two handles increases the size of the battery, making it unsuitable for smaller spaces and limiting its usage scenarios. Utility Model Content

[0005] In view of this, this application provides a battery to solve the problem that setting two handles on the battery will increase the size of the battery, making it unable to fit into a small space and limiting the battery's usage scenarios.

[0006] This application provides a battery, which includes a housing, a handle, and a connector. The housing has a sliding groove, and the connector passes through the handle and the sliding groove. The handle is rotatable around the connector, and the connector is slidable within the sliding groove, so that the handle can move between a first position and a second position.

[0007] When the handle is in the first position, a portion of the handle protrudes relative to the housing along a first direction;

[0008] When the handle is in the second position, a portion of the handle protrudes relative to the housing along a second direction, the first direction intersecting the second direction.

[0009] Preferably, the sliding groove extends along the first direction, and the groove wall of the sliding groove includes a first abutting surface and a second abutting surface facing each other in the first direction;

[0010] When the handle is in the first position, the connector abuts against the first contact surface;

[0011] When the handle is in the second position, the connector abuts against the second contact surface.

[0012] Preferably, the housing further includes a locking element that can lock the handle or the connector when the handle is in the second position.

[0014] When the handle is in the first position, the connector abuts against the first contact surface;

[0015] When the handle is in the second position, the connector abuts against the second contact surface.

[0016] Preferably, the outer shell includes a housing, the housing includes a first plate portion, and the first plate portion has the sliding groove;

[0017] The battery also includes fasteners located inside the housing and connected to the connector. The fasteners are at least partially capable of abutting against the side of the first plate facing the interior of the housing.

[0018] Preferably, the housing further includes a surrounding member located inside the housing and connected to the first plate portion. The surrounding member and the first plate portion enclose a receiving cavity, and the fastener is located inside the receiving cavity.

[0019] Preferably, there are two first plate portions and two connectors. The two first plate portions are arranged at intervals along a third direction. The two connectors correspond to the two sliding grooves respectively. The connectors pass through the handle and the sliding grooves corresponding to the connectors. The third direction intersects the plane determined by the first direction and the second direction.

[0020] Preferably, a plane passing through the center of gravity of the battery and perpendicular to the second direction is defined as the first plane, and a plane passing through the center of gravity of the battery and perpendicular to the first direction is defined as the second plane;

[0021] When the handle is in the first position, the axis of the connector is located on the first plane;

[0022] When the handle is in the second position, the axis of the connector is located on the second plane.

[0023] Preferably, the handle includes a rubber-coated portion, a lifting portion, and two connecting portions. The lifting portion is connected to the two connecting portions at its two ends in the third direction, and the two connecting portions are respectively passed through by the two connecting members.

[0026] The battery of this application includes a casing, a handle, and a connector. The casing has a sliding groove, and the connector passes through the handle and the sliding groove. The handle can rotate around the connector, and the connector can slide within the sliding groove, allowing the handle to move between a first position and a second position. When handling the battery in an upright position, the handle can be in the first position, where a portion of the handle protrudes relative to the casing in a first direction, allowing the operator to lift the battery. When handling the battery in a horizontal position, the handle is rotated to the second position, where a portion of the handle protrudes relative to the casing in a second direction, allowing the operator to lift the battery. Thus, a single handle can meet the handling needs of batteries in both upright and horizontal positions. The overall size of the battery is small, allowing it to fit into smaller spaces and thus expanding its application scenarios. Attached Figure Description

Detailed Implementation

[0037] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0038] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0039] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0040] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0041] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0042] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0043] The terminology used herein is for the purpose of describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0044] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0045] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0046] The following will combine Figures 1 to 8 Describe the battery, in Figures 1 to 8 In the diagram, the first direction L1 intersects with the second direction L2, and the third direction L3 intersects with the plane defined by the first direction L1 and the second direction L2. Preferably, the intersection is perpendicular. The following description of the battery will be based on the example of the first direction L1, the second direction L2, and the third direction L3 being perpendicular to each other.

[0047] like Figures 1 to 8 As shown, the battery includes a casing 1, a handle 2, and a connector 3. The casing 1 has a sliding groove 123. The connector 3 passes through the handle 2 and the sliding groove 123. The handle 2 can rotate around the connector 3, and the connector 3 can slide within the sliding groove 123, allowing the handle 2 to move between a first position and a second position. When handling the battery in an upright position, the handle 2 can be in the first position, where a portion of the handle 2 protrudes relative to the casing 1 along a first direction L1. The operator can lift the handle 2 to move the battery. When handling the battery in a horizontal position, the handle 2 is rotated to the second position, where a portion of the handle 2 protrudes relative to the casing 1 along a second direction L2. The operator can lift the handle 2 to move the battery. Thus, a single handle 2 can meet the handling needs of the battery in both upright and horizontal positions. The overall size of the battery is small, allowing it to fit into smaller spaces, thereby enriching the battery's usage scenarios. Furthermore, using the handle for handling in both upright and horizontal positions improves the utilization rate of the handle.

[0048] Furthermore, when the battery is in a vertical position, the first direction L1 is parallel to the direction of gravity; when the battery is in a horizontal position, the second direction L2 is parallel to the direction of gravity.

[0049] like Figure 2 and Figure 3 As shown, the outer casing 1 includes a box body 12, a cover 13, and a bottom plate 11. The box body 12 includes two first plate portions 121 and two second plate portions 122. The two first plate portions 121 are arranged at intervals along a third direction L3, and the two second plate portions 122 are arranged at intervals along a second direction L2. For any one first plate portion 121, both ends of the first plate portion 121 in the second direction L2 are respectively connected to the two second plate portions 122. The entire box body 12 is rectangular. The box body 12 has two openings that are opposite to each other in the first direction L1. The bottom plate 11 covers one opening, and the cover 13 covers the other opening.

[0050] A first plane is defined as the plane passing through the battery's center of gravity and perpendicular to the second direction L2, and a second plane is defined as the plane passing through the battery's center of gravity and perpendicular to the first direction L1. When the handle 2 is in the first position, the axis of the connector 3 lies on the first plane; when the handle 2 is in the second position, the axis of the connector 3 lies on the second plane. In other words, whether the handle 2 is in the first or second position, the axis of the connector 3 can lie on the plane containing the battery's center of gravity, which ensures the stability of battery handling.

[0051] It should be noted that the first plane and the second plane mentioned above are only for the purpose of illustrating the position of the connector 3. In the actual battery, the first plane and the second plane do not exist.

[0052] Optionally, the sliding groove 123 may extend along the first direction L1, or the sliding groove 123 may include two parts: a first groove portion 1231 and a second groove portion 1232.

[0053] In Example 1, as Figures 1 to 5 In the first plate portion 121, a sliding groove 123 is provided, extending along a first direction L1. When switching the handle 2 from the first position to the second position or from the second position to the first position, the handle 2 can be rotated 90 degrees and pushed to move, causing the connecting member 3 to slide within the sliding groove 123, thereby achieving the switching of the handle 2's position. Since the connecting member 3 can slide within the sliding groove 123, a smaller handle 2 can meet the handling requirements in both states, thus reducing the cost of the handle 2.

[0054] Optionally, such as Figure 5As shown, the wall of the sliding groove 123 includes a first abutting surface S1, a second abutting surface S2, and two limiting surfaces S3. The first abutting surface S1 and the second abutting surface S2 face each other in a first direction L1, and the two limiting surfaces S3 face each other in a second direction L2. The first abutting surface S1 and the second abutting surface S2 can be curved surfaces, and the limiting surface S3 can be a plane. The first abutting surface S1 is located on the side closer to the cover 13, and the second abutting surface S2 is located on the side closer to the bottom plate 11. When the handle 2 is in the first position, the connecting piece 3 abuts against the first abutting surface S1. When switching the handle 2 to the second position, the handle 2 can be rotated 90 degrees and pushed to move, so that the connecting piece 3 slides in the sliding groove 123. When the connecting piece 3 abuts against the second abutting surface S2, the handle 2 is switched to the second position.

[0055] In this embodiment, as Figure 4 As shown, the battery also includes a fastener 4, which is located inside the housing 12. The fastener 4 is connected to the connector 3, and at least a portion of the fastener 4 can abut against the side of the first plate 121 facing the inside of the housing 12. Thus, by providing the fastener 4, the position of the connector 3 can be limited to prevent it from falling off, thereby ensuring the stability of the handle 2.

[0056] Optionally, the connector 3 can be a screw and the fastener 4 can be a nut. In this case, the connector 3 and the fastener 4 are fixed by a threaded connection. The nut can be a structure with equal outer diameters, in which case the outer diameter of the nut is larger than the size of the sliding groove 123 in the second direction L2; the nut can also include two parts with unequal outer diameters, in which case only one part needs to have an outer diameter larger than the size of the sliding groove 123 in the second direction L2.

[0057] like Figure 4 and Figure 5 As shown, the outer casing 1 also includes a surrounding member 124, which is located inside the housing 12 and connected to the first plate portion 121. The surrounding member 124 and the first plate portion 121 enclose a receiving cavity, in which the fastener 4 is located. Thus, when the connector 3 slides within the sliding groove 123, the fastener 4 slides within the receiving cavity. The surrounding member 124 can isolate the fastener 4 from the battery cell located in the housing 12, thereby preventing the fastener 4 from damaging the battery cell inside.

[0058] Optionally, the size of the surrounding member 124 in the first direction L1 is larger than the size of the sliding groove 123 in the first direction L1, so as to ensure that the fastener 4 always slides within the receiving cavity.

[0059] Preferably, the size of the surrounding member 124 in the first direction L1 is equal to the size of the first plate portion 121 in the first direction L1.

[0060] Preferably, there are two connectors 3, each corresponding to one of the two sliding grooves 123. The connectors 3 pass through the handle 2 and the corresponding sliding grooves 123. Each connector 3 is provided with a fastener 4, and the two fasteners 4 are located in the two receiving cavities. In this way, both ends of the handle 2 are connected to the housing 12, which can improve the uniformity of force on the housing 12 when handling the battery, thereby improving the stability of the battery handling process.

[0061] Preferably, the two surrounding parts 124 and the box body 12 can be integrally formed, the bottom plate 11 and the box body 12 can be fixed with screws, and the cover 13 and the box body 12 can also be fixed with screws.

[0062] In Embodiment 2, the sliding groove 123 is in the same form as the sliding groove 123 in Embodiment 1. In Embodiment 2, the battery also includes a locking member 5. When the handle 2 is in the second position, the locking member 5 can lock the handle 2 or the connecting member 3, which can prevent the handle 2 from shifting during battery transportation, thereby improving the stability of battery transportation.

[0063] Optionally, the form of the locking element 5 can be selected according to requirements, for example, such as... Figure 6 As shown, the locking element 5 can be a rubber plate, which is fixed to the first plate portion 121 by screws. When the hand 2 is in the second position, the rubber plate is stretched, causing part of the connecting member 3 to enter the hole in the rubber plate, thereby locking the connecting member. Alternatively, the locking element 5 can include a locking plate and a rotating shaft. The locking plate is connected to the first plate portion 121 via the rotating shaft and can rotate around the rotating shaft. When the handle 2 is in the second position, rotating the locking plate causes it to engage with the connecting member 3, thereby locking the connecting member 3.

[0064] In Example 3, as Figure 7 and Figure 8As shown, the sliding groove 123 may include two parts: a first groove portion 1231 extending along a first direction L1 and a second groove portion 1232 extending along a second direction L2. The end of the first groove portion 1231 near the bottom plate 11 is connected to the second groove portion 1232, that is, the entire sliding groove 123 is "L" shaped. The groove wall of the first groove portion 1231 includes a first abutting surface S1 and a connecting surface S4 facing each other in the first direction L1. The first abutting surface S1 is located on the side near the cover 13, and the connecting surface S4 is located on the side near the bottom plate 11. The second groove portion 1232 is connected to the end of the first groove portion 1231 where the connecting surface S4 is located. The groove wall of the second groove portion 1232 includes a second abutting surface S2 facing the first groove portion 1231 in the second direction L2. When the handle 2 is in the first position, the connecting member 3 abuts against the first abutting surface S1. When switching handle 2 to the second position, handle 2 can be rotated 90 degrees and pushed to allow connector 3 to slide along the first direction L1 within the first groove 1231. Then, push handle 2 to allow connector 3 to slide along the second direction L2 within the second groove 1232. When connector 3 abuts against the second contact surface S2, handle 2 is switched to the second position. Thus, when handle 2 is in the second position, the second groove 1232 can limit handle 2 to prevent it from shifting in the first direction L1, thereby improving the stability of battery handling.

[0065] Optionally, in this embodiment, the shape of the surrounding member 124 is adapted to the shape of the sliding groove 123 to ensure that the fastener 4 connected to the connector 3 always moves within the receiving cavity enclosed by the surrounding member 124 and the first plate portion 121.

[0066] In the above embodiments one to three, the handle 2 includes a lifting portion 21 and two connecting portions 22. Both the lifting portion 21 and the connecting portions 22 are plate-like structures. The two ends of the lifting portion 21 in the third direction L3 are respectively connected to the two connecting portions 22, and the two connecting portions 22 are respectively passed through by two connecting pieces 3. When the handle 2 is in the first position, as... Figure 2 As shown, the lifting part 21 protrudes relative to the outer shell 1 along the first direction L1. The lifting part 21 and the cover 13 are located on the same side of the first direction L1, and the lifting part 21 and the cover 13 are spaced apart along the first direction L1. When the handle 2 is in the second position, as... Figure 3 As shown, the lifting part 21 protrudes relative to the outer casing 1 along the second direction L2. The lifting part 21 and a second plate part 122 are located on the same side, and the lifting part 21 and the second plate part 122 are spaced apart. Thus, when the handle 2 is in the first position and the second position, the lifting part 21 can protrude relative to the outer casing 1, and the operator can carry the battery by holding the lifting part 21.

[0067] Preferably, the entire handle 2 is integrally formed.

[0068] Furthermore, the handle 2 also includes a rubber-coated portion 23, which covers at least a portion of the lifting portion 21. When handling the battery, the operator can hold the battery by gripping the rubber-coated portion 23, which improves the stability of the operator's grip and prevents the battery from slipping during handling.

[0069] Optionally, the overmolded portion 23 may cover only the middle part of the lifting portion 21, or it may cover the entire lifting portion 21.

[0070] In addition, such as Figure 4 As shown, a first mounting groove 131 is formed on the side of the cover 13 facing away from the base plate 11. When the battery is not being transported, a portion of the lifting part 21 can be placed in the first mounting groove 131, which reduces the space occupied by the battery when it is not being transported. When a portion of the lifting part 21 is placed in the first mounting groove 131, the connector 3 is located at the middle position of the sliding groove 123 in the first direction L1.

[0071] Optionally, the cover 13 has a second mounting groove 132 formed on both sides in the second direction L2, and the two ends of the first mounting groove 131 are respectively connected to the two second mounting grooves 132.

[0072] When the battery in Example 1 is not moved, such as Figure 1 As shown, part of the lifting part 21 is placed in the first mounting groove 131. When the battery is in a vertical position, the first direction L1 is parallel to the direction of gravity. When it needs to be moved, the handle 2 is pushed along the first direction L1 until the connector 3 abuts against the first contact surface S1. At this time, as shown... Figure 2 As shown, handle 2 is in the first position, and the lifting part 21 protrudes from the outer shell 1 along the first direction L1. The battery can then be moved by gripping the rubber-coated part 23. After the battery is moved, push handle 2 so that part of the lifting part 21 is placed in the first mounting groove 131, thus completing the reset of handle 2. When the battery is in a horizontal position, the second direction L2 is parallel to the direction of gravity. When it needs to be moved, push handle 2 along the first direction L1 until the connecting member 3 abuts against the first contact surface S1. Then rotate handle 2 90 degrees and push handle 2 along the first direction L1 until the connecting member 3 abuts against the second contact surface S2. At this time, as... Figure 3 As shown, the handle 2 is in the second position, and the lifting part 21 protrudes from the outer shell 1 along the second direction L2. Then, the battery can be moved by holding the rubber-coated part 23. After the battery is moved, the handle 2 is pushed along the first direction L1 until the connector 3 abuts against the first contact surface S1. Then, the handle 2 is rotated 90 degrees and pushed along the first direction L1 until the part of the lifting part 21 is placed in the first placement groove 131, thereby completing the reset of the handle 2.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
