In the present application, the battery cell may include a lithium ion secondary battery, a lithium ion primary battery, a lithium sulfur battery, a sodium lithium ion battery, a sodium ion battery, a magnesium ion battery, or the like, which is not limited in the embodiments of the present application. The battery cell may be a cylinder, a flat body, a rectangular parallelepiped, or other shapes, which is not limited in the embodiments of the present application. The battery cells are generally divided into three types in an encapsulation manner: the cylindrical battery monomer, the square battery monomer and the soft package battery monomer are not limited in the embodiment of the application.

Reference to a battery in embodiments of the present application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery referred to in the present application may include a battery module or a battery pack, etc. Batteries generally include a case for enclosing one or more battery cells. The box body can prevent liquid or other foreign matters from influencing the charging or discharging of the battery cells.

The battery monomer comprises an electrode assembly and electrolyte, wherein the electrode assembly comprises a positive plate, a negative plate and an isolating membrane. The battery cell mainly depends on metal ions moving between the positive plate and the negative plate to work. The positive plate comprises a positive current collector and a positive active substance layer, wherein the positive active substance layer is coated on the surface of the positive current collector, the current collector which is not coated with the positive active substance layer protrudes out of the current collector which is coated with the positive active substance layer, and the current collector which is not coated with the positive active substance layer is used as a positive electrode lug. Taking a lithium ion battery as an example, the material of the positive electrode current collector may be aluminum, and the positive electrode active material may be lithium cobaltate, lithium iron phosphate, ternary lithium, lithium manganate, or the like. The negative pole piece includes negative current collector and negative pole active substance layer, and the negative pole active substance layer coats in the surface of negative current collector, and the mass flow body protrusion in the mass flow body of coating the negative pole active substance layer of uncoated negative pole active substance layer, the mass flow body of uncoated negative pole active substance layer is as negative pole utmost point ear. The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon, silicon, or the like. In order to ensure that the fuse is not fused when a large current is passed, the number of the positive electrode tabs is multiple and the positive electrode tabs are stacked together, and the number of the negative electrode tabs is multiple and the negative electrode tabs are stacked together. The material of the diaphragm can be PP or PE, etc. In addition, the electrode assembly may have a winding structure or a lamination structure, and the embodiment of the present application is not limited thereto.

The applicant found that: when the small-sized battery needs to be manually carried in the application of battery replacement and the like, and the battery is changed in direction and position, an attempt is made to provide a structure which is favorable for manual carrying on the box body, for example, a groove for hand grasping is formed on the box body. However, the applicant has found that when the battery is inside the electric device, it is difficult to remove the battery from the electric device by gripping the grooves provided on the case with both hands due to the shielding of other mechanisms. The applicant has found through research that if the direction and position of the battery in the battery replacement application are to be changed, it is necessary to be able to pull the battery from two directions simultaneously. In view of the above, the present application solves the above technical problem by providing a handle that can pull a battery from two directions.

The technical scheme described in the embodiment of the application is applicable to various devices using batteries, such as mobile phones, portable devices, notebook computers, battery cars, electric toys, electric tools, electric vehicles, ships, spacecrafts and the like, and the spacecrafts comprise airplanes, rockets, space shuttles, spacecrafts and the like.

It should be understood that the technical solutions described in the embodiments of the present application are not limited to be applied to the above-described devices, but may also be applied to all devices using batteries, and for brevity of description, the following embodiments are all described by taking an electric vehicle as an example. As shown in fig. 1, which is a schematic structural diagram of a vehicle 1 according to an embodiment of the present disclosure, the vehicle 1 may be a fuel-oil vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid electric vehicle, or an extended range vehicle. A drive motor 2 is mounted on the front axle of the two front wheels of the vehicle 1. Further, the vehicle 1 is equipped with a controller 3 and a battery 10. As is well known to those skilled in the art, the controller 3 and the battery 10 are typically disposed at appropriate locations on the primary axle of the vehicle 1 to control the operation of the various components of the vehicle 1 and to provide driving power for the vehicle 1.

Fig. 2 and 3 are schematic perspective views and exploded views of a battery 10 according to an embodiment of the present disclosure. The battery 10 includes a case 11 having a substantially rectangular parallelepiped shape, and at least one battery cell (not shown in the drawings) is housed in the case 11.

In order to meet different power requirements, a plurality of battery cells may be accommodated in the box 11, wherein the plurality of battery cells may be connected in series or in parallel or in series-parallel, and the series-parallel refers to a mixture of series connection and parallel connection. Battery 10 may also be referred to as a battery pack. Alternatively, a plurality of battery cells may be connected in series or in parallel or in series-parallel to form a battery module, and a plurality of battery modules may be connected in series or in parallel or in series-parallel to form the battery 10. That is, a plurality of battery cells may directly constitute the battery 10, or a battery module may be first constituted and then the battery 10 may be constituted.

The cabinet 11 includes a front wall 111, a rear wall 113, a top cover 112, a bottom wall (obscured by other walls in the drawing), and two opposite side walls. It should be noted that the terms "front wall", "rear wall", and the like as used herein are determined based only on the placement direction of the cabinet 11 shown in fig. 2 and 3, and do not uniquely correspond to a certain wall surface of the cabinet 11.

The receiving portions are formed on at least two adjacent surfaces of the front wall 111, the rear wall 113, the top cover 112, the bottom wall, and the two side walls, based on the direction in which the battery 10 needs to be pulled in practical use. In the embodiment shown in fig. 2 and 3, the case 11 is formed with the accommodating portions on both the surface of the top cover 112 as the first surface and the surface of the front wall 111 as the second surface. However, it is obvious to those skilled in the art that the accommodating parts may be formed on the surface of the top cover 112, the surface of the front wall 111, the surface of the bottom wall and the surface of the rear wall 113, or the accommodating parts may be formed on the surface of the top cover 112, the surface of at least one side wall and the surface of the bottom wall, etc. according to the actual requirement. Such variations should be readily apparent to one of ordinary skill in the art.

As shown in fig. 3, the receiving portion includes a first receiving groove 121 formed on a surface of the front wall 111 and a second receiving groove 122 formed on a surface of the top cover 112. Alternatively, the first receiving groove 121 and the second receiving groove 122 are formed along the substantial center lines of the front wall 111 and the top cover 112. The first and second receiving

grooves

121, 122 are optionally flat strip-like grooves sized to receive a handle 13 made, for example, of a single woven or other strip-like element. In the case where the first receiving groove 121 and the second receiving groove 122 are located approximately at the center of the front wall 111 and the top cover 112, the first receiving groove 121 and/or the second receiving groove 122 may be partially expanded outward into an arc-shaped portion 124, so that an operator can insert a palm into the first receiving groove 121 and/or the second receiving groove 122 and firmly hold the handle 13 received therein. In addition, the depth of the second receiving groove 122 formed on the surface of the top cover 112 may be slightly greater than the depth of the first receiving groove 121 formed on the surface of the front wall 111 in consideration of the thickness of the top cover 112. Of course, other accommodating parts may be employed instead of the first and second

accommodating grooves

121, 122. All such modifications are intended to be included within the scope of this application.

At other positions of the top cover 112 where the second receiving groove 122 is not provided, for example, at a certain corner position, an interface 123 is formed for electrically connecting the battery cells received in the case 11 with a cable leading to the outside.

With continued reference to fig. 3, handle 13 mounted to case 11 will now be described.

Handle 13 includes a first end portion 131, a second end portion 132, and a flexible body portion 130 connecting first end portion 131 and second end portion 132. The first end portion 131 includes a first fixing portion 133, and the first fixing portion 133 is used for fixing the first end portion 131 to a first surface of the case 11, for example, a surface of the top cover 112 of the case 11. Similarly, the second end 132 includes a second fixing portion 134, and the second fixing portion 134 is used for fixing the second end 132 to a second surface of the box 11, for example, a surface of the front wall 111 of the box 11. The flexible body portion 130 may alternatively be a band, such as a band made of a single strap, webbing, or other suitable flexible material, so long as it is of suitable strength and of reasonable cost. The flexible body portion 130 has suitable elasticity and ductility and is capable of bending at the interface of two adjacent surfaces of the housing 11.

A rubber sleeve 135 may also be fitted to handle 13 for an operator to hold when lifting battery 10. Optionally, a rubber sleeve 135 is disposed in the flexible body portion 130 at a location corresponding to the curved portion 124 to cooperate with the curved portion 124 to facilitate gripping of the handle 13 by the palm of the operator's hand.

In addition, the handle 13 optionally includes at least one limiting portion 136, and the limiting portion 136 passes through a limiting groove 1361 opened in the box body 11 to limit at least a portion of the limiting portion 136 in the limiting groove 1361.

Referring to fig. 1, 4 and 6, a first fixing portion 133 and a second fixing portion 134 surrounded by circles a and C in fig. 1 are shown. In this example, the first fixing portion 133 is used to fix the first end portion 131 of the handle 13 to an upper portion of the box 11, and the second fixing portion 134 is used to fix the second end portion 132 of the handle 13 to a lower portion of the box 11. It can be understood by those skilled in the art that the replacement of the fixing positions of the first and second fixing

portions

133 and 134 with each other or the replacement of one or both of the first and second fixing

portions

133 and 134 with other fixing structures should be considered to fall within the scope of the present application.

It can be seen that the flexible main body portion 130 fixes the first end portion 131 to the surface of the top cover 112 of the housing 11 through the first fixing portion 133 in the area surrounded by the circle a shown in fig. 4. The first fixing portion 133 includes a generally L-shaped insert 1331, the L-shaped insert 1331 being configured to be inserted into a corresponding slot 1335 provided on the case 11 and fixed to the case 11 by means of a fastener 1336. As shown in fig. 4, L-shaped tab 1331 is an integral part of a first tab portion 1332 parallel to the surface of top cover 112 and a second tab portion 1333 perpendicular to the surface of top cover 112.

The first tab portion 1332 is formed with a slit 1334 into which the flexible main body portion 130 can be inserted, and one end of the flexible main body portion 130 can be fixed to the first tab portion 1332 of the L-shaped tab 1331 in such a manner as to pass through the slit 1334 and be wound around the first tab portion 1332.

The second tab portion 1333 is adapted to be inserted into a corresponding slot 1335 provided in the case 11. Strictly speaking, the insertion groove 1335 includes a recess formed at one end of the second receiving groove 122 of the top cover 112, and the recess and the edge of the rear wall 113 of the case 11 together form the insertion groove 1335. At least one, optionally a pair of screw holes are formed on the second insert portion 1333, and at least one, optionally a pair of mating screw holes are also formed on the rear wall 113 of the box body 11. The dimensions of the mating screw holes on the rear wall 113 and the screw holes on the second tab portion 1333 are adapted to each other such that at least one, and optionally a pair of, fasteners 1336 can pass through the screw holes to secure the second tab portion 1333 in the slot 1335, thereby allowing the flexible body portion 130 to secure the first end portion 131 to the surface of the top cover 112 of the case 11 via the first securing portion 133.

Similarly, in the area surrounded by circle C shown in fig. 6, the flexible main body portion 130 fixes the second end portion 132 to the surface of the front wall 111 of the case 11 by the second fixing portion 134. Unlike the first fixing portion 133 in fig. 4, the second fixing portion 134 includes an insertion piece 1341, and the insertion piece 1341 is configured to be inserted into a corresponding insertion slot 1345 provided on the case 11 and fixed to the case 11 by a fastener 1346. As shown in fig. 6, the straight insertion piece 1341 is formed by a flat metal sheet parallel to the surface of the front wall 111 of the box 11, the straight insertion piece 1341 is formed with a slit 1344 into which the flexible main body 130 can be inserted, and the flexible main body 130 can be fixed to the straight insertion piece 1341 by passing through the slit 1344 and winding on the straight insertion piece 1341.

The first receiving groove 121 formed on the surface of the front wall 111 of the case 11 has an angle iron piece 1342 welded thereto at a position interfacing with the bottom wall of the case 11. One end of the angle piece 1342 is welded to the bottom wall, and the other end and the first accommodating groove 121 together form an inserting groove 1345. The straight insertion piece 1341 is formed with at least one, optionally a pair of screw holes, and the angle iron piece 1342 is also formed with at least one, optionally a pair of matching screw holes. The dimensions of the mating screw holes on the angle iron 1342 and the screw holes on the in-line plate 1341 are adapted to each other such that at least one, and optionally a pair of fasteners 1346 can pass through these screw holes to secure the in-line plate 1341 in the slot 1345, thereby enabling the flexible body portion 130 to secure the second end portion 132 to the surface of the front wall 111 of the case 11 via the second securing portion 134. The angle steel piece 1342 is arranged, the straight insertion piece 1341 and the angle insertion piece 1342 are fixedly connected, so that holes in the box body 11 can be avoided, and the air tightness of the box body 11 is guaranteed while the handle is fixed on the surface of the front wall 111 of the box body 11.

Alternatively, the angle piece 1342 welded to the bottom wall as described above may be replaced with a straight steel piece welded to the front wall 111 of the cabinet 11, such replacement should be readily apparent to one of ordinary skill in the art.

Referring to fig. 1, 5 and 7, the position-limiting portion 136 surrounded by the circle B in fig. 1 and the position-limiting groove 1361 opened in the box 11 are shown.

The position of the limiting portion 136 on the flexible main body portion 130 corresponds to the boundary between two adjacent surfaces of the case 11, so that the limiting portion can pass through the limiting groove 1361 provided in the case 11 to limit at least a part of the limiting portion 136 in the limiting groove 1361. The stop portion 136 is optionally made of a hard material, such as rubber, to facilitate its more secure retention in the stop slot 1361. In this example, the stopper 136 includes a stepped portion 1362 that is snap-fitted with the stopper groove 1361.

With continued reference to fig. 5 and 7, the restraint slot 1361 is configured as an inverted T-shaped slot. This design has the following two advantages: on the one hand, to facilitate insertion of the flexible body portion 130 into the restraint slot 1361; and on the other hand facilitates abutting and secure retention of flexible body portion 130 against step 1362. Specifically, the operator first applies a force locally to the flexible main body portion 130 to stretch the flexible main body portion 130 having elasticity and extensibility. Next, at least a portion of the flexible main body portion 130 other than the portion where the stopper 136 is provided is bent along a center line thereof and then inserted into the stopper groove 1361, and then the bent portion is unfolded and laid flat in the stopper groove 1361. Thereafter, the force applied to the flexible main body portion 130 is stopped, and since the flexible main body portion 130 itself has elasticity and ductility, the flexible main body portion 130 will tend to return to its original state, causing the stepped portion 1362 as the stopper portion 136 to move toward the inverted T-shaped stopper groove 1361, and finally to be fitted and firmly held in the stopper groove 1361.

While an embodiment of the battery 10 according to the present application has been specifically described above, it will be apparent to those skilled in the art that various modifications may be made to the battery 10 based on the embodiment, and such modifications are intended to fall within the scope of the present application.

For example, fig. 8 to 11 show another alternative of the first and second fixing

portions

233 and 234 of the handle 13. This alternative introduces an inverted T-shaped slot for the spacing groove into the fixation section to replace the fastener-type fixation structure employed in the previous embodiment. Thus, when handle 13 is assembled to battery 10, time for fastening the fastener can be saved, thereby improving the assembly efficiency of handle 13.

Specifically, referring to fig. 1, 8 and 9, there is shown a first fixing portion 233 for fixing one end of the flexible body portion 130 to an upper portion of the case 11; referring to fig. 1, 10 and 11, a second fixing portion 234 for fixing the other end of the flexible body portion 130 to a lower portion of the case 11 is shown, wherein the first and second fixing

portions

233 and 234 are substantially identical in structure.

As shown in fig. 1, 8, 9 and 11, one end of flexible body portion 130 is wrapped around and secured to a catch 2331, which is typically made of metal or other hard material. Latch 2331 optionally has a generally C-shape, in other words, latch 2331 is made in the form of a rectangular loop having first and second long sides with and without notches that are generally parallel to each other and first and second short sides that are generally parallel to each other. The length of the second long side of retainer 2331 without a notch is defined as "insertion length L1 of retainer 2331". Insertion length L1 of catch 2331 should be no less than or slightly greater than the width of flexible body portion 130, thereby allowing flexible body portion 130 to wrap around the second long side of catch 2331.

Alternatively, the first fixing portion 233 or the second fixing portion 234 may further include a flexible sleeve portion 2332 integrally formed at one end of the flexible body portion 130.

Referring to fig. 9 and 11, a locking groove 2333 is formed in the top of the rear wall 112 of the case 11, and the locking length L2 of the locking groove 2333 along the case 11 is shorter than the insertion length L1 of the locking piece 2331. With the above design, an operator can insert latch 2331 into latch groove 2333 by tilting it at a first angle and return latch 2331 to a second angle parallel to latch groove 2333 or rear wall 112 of case 11 after insertion. Since the insertion length L1 of the locking piece 2331 is longer than the locking length L2 of the locking groove 2333, that is, the length of the side of the locking piece 2331 abutting against the case 11 is longer than the locking length L2 of the locking groove 2333, the locking piece 2331 cannot be withdrawn out of the case 11 through the locking groove 2333 and is fixed to the surface of the case 11. Compared with the previous embodiment, the embodiment avoids the operations of bolt connection, welding and the like, and improves the assembly efficiency of the battery.

To accommodate catch 2331 into housing 11, a punch 2334 is formed in housing 11 to accommodate catch 2331. This punch-bag structure 2334 can be clearly seen in fig. 11, as previously described, the size of the punch-bag structure 2334 is entirely dependent on the size of the catch 2331 and the height of the catch slot 2333 from the edge of the rear wall 113 of the case 11.

It can be understood by those skilled in the art that in the handle 13 used in the battery 10 according to the present application, both the first and second fixing

portions

133 and 134 may be designed as the fastener type fixing structure used in the specific embodiment, the first and second fixing

portions

233 and 234 may be designed as the snap type fixing structure used in the alternative manner, and one of the two fixing portions may be designed as the fastener type fixing structure and the other as the snap type fixing structure. It is within the scope of the present application to provide any one of the above structures for the fixing portion according to different requirements.

In addition, fig. 12 and 13 also show various alternatives for the

stop portions

236 and 336.

For example, a stopper groove 1361 formed in the case 11 may be provided in the top cover 112 of the case 11. As shown in fig. 12, a T-shaped groove into which the flexible main body portion 130 can be inserted is formed at a substantially central position of at least one edge of the top cover 112, and the T-shaped groove serves as an upper limit groove 2361 for limiting the flexible main body portion 130.

Alternatively, as shown in fig. 13, a T-shaped groove may be formed at the lower edge of the case 11 as a lower limit groove 3361 for limiting the flexible main body 130.

Fig. 14 is an exploded view of a battery according to another embodiment of the present application, and fig. 15 is a partial view of a receiving portion on a first surface of a case. It can be seen that the case is fitted with a handle 13 for the battery 10, comprising a housing formed at least on the front wall 111 and on the rear wall 113 of the case, the flexible body portion 130 of the handle 13 being configured to surround the case and be housed in the housing. The case also includes at least one upper retention slot 2361 that traps at least a portion of the flexible body portion 130 in the receptacle to enable the battery 10 to be pulled in two directions.

More specifically, a pair of upper limiting grooves 2361 are provided on opposite edges of the top cover 112 of the battery 10, and receiving parts are provided on the front wall 111 and the rear wall 113 of the battery 10, wherein the receiving part formed on the front wall 111 is the first receiving groove 121 and the receiving part formed on the rear wall 113 is the second receiving groove 122. Thus, the flexible body portion 130 of the handle 13 can pass through the upper limiting groove 2361 and be received in the first receiving groove 121 and the second receiving groove 122 on the front wall 111 and the rear wall 113. Compared with the previous embodiment, the handle 13 of this embodiment adopts a four-side surrounding design, and is limited by the top cover 112, the first receiving groove 121 and the second receiving groove 122, so that the structure is simpler.
