For electric vehicles, battery technology is an important factor in their development.

[0003] The battery shell includes a shell and an end cap, and the end cap covers the opening of the shell. When installing the battery, the end cap needs to be connected to the shell. In the related art, the staff presses the end cap and the shell together, but the manual installation speed is slow and the battery production efficiency is low. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems in the background technology. To this end, one purpose of the present application is to provide a battery housing installation device and a battery manufacturing device to increase the installation speed of the battery housing and improve the production efficiency of the battery.

[0005] An embodiment of the first aspect of the present application provides a battery shell installation device, the battery shell includes a shell and an end cover, the battery shell installation device includes: a support mechanism; a base mechanism, connected to the support mechanism, the base mechanism is configured to place the end cover and the shell, the end cover covers the opening of the shell; a press-fitting mechanism, connected to the support mechanism, when the battery shell is located on the base mechanism, the press-fitting mechanism and the base mechanism are located on opposite sides of the battery shell along a first direction, and the press-fitting mechanism is configured to provide pressure to the end cover toward the shell or to provide pressure to the shell toward the end cover so that the end cover is connected to the shell.

[0006] In the technical solution of the embodiment of the present application, when using the battery casing installation device provided in the embodiment of the present application, the end cover and the shell are placed on the base mechanism, and the end cover covers the opening of the shell, and then the pressing mechanism is controlled to provide pressure to the end cover toward the shell or to provide pressure to the shell toward the end cover, so that the end cover is connected to the shell, and mechanical pressing is achieved. The pressing speed is fast, which improves the efficiency of battery casing installation, that is, improves the production efficiency of the battery.

[0007] In some embodiments, the press-fitting mechanism includes: a sliding assembly slidably connected to the support mechanism, the sliding direction of the sliding assembly being the same as the first direction; a pressure assembly connected to the sliding assembly, the pressure assembly being located between the sliding assembly and the base mechanism; wherein the sliding assembly is configured to push the pressure assembly to apply pressure to the battery housing under the action of pressure. The sliding of the sliding assembly can be controlled to drive the pressure assembly to move, so that the pressure assembly can apply pressure to the battery housing, which is more convenient.

[0008] In some embodiments, the pressure assembly includes: a pressure seat, connected to the sliding assembly; an elastic element, movably and elastically connected to the pressure seat, the movable direction of the elastic element is the same as the first direction; a locking element, connected to the pressure seat; wherein, when the elastic force of the elastic element is less than the first preset elastic force value, one end of the elastic element toward the base mechanism is against the locking element, and when the elastic force of the elastic element is greater than or equal to the first preset elastic force value, the locking element moves along the second direction, so that the elastic element moves toward the base mechanism along the first direction and provides pressure to the battery housing, and the first direction intersects with the second direction. In the related art, the battery housing is manually pressed by the staff, and the pressure applied to the battery housing by the staff during the pressing process cannot be guaranteed to be consistent, resulting in poor pressing effect. In an embodiment of the present application, through the pressure seat, the elastic element and the locking element, the elastic element applies an impact force along the first direction to the battery housing under the action of the elastic force, so that the shell and the end cover are connected. That is, the pressure applied to the battery casing comes from the elastic force of the elastic element. The elastic force of the elastic element is certain. During the press-fitting process, the pressure applied by the pressure component to the battery casing is less different, and the press-fitting effect is better and the uniformity is better.

[0009] In some embodiments, the pressure seat includes: a first mounting plate connected to the sliding assembly; a second mounting plate stacked with the first mounting plate, and the second mounting plate is located on the side of the first mounting plate away from the sliding assembly; a first connecting shaft extending along a first direction, one end of the first connecting shaft fixedly connected to the second mounting plate, and the other end of the first connecting shaft movably connected to the first mounting plate; a first elastic element sleeved on the first connecting shaft, and the opposite ends of the first elastic element respectively abut against the first mounting plate and the second mounting plate; wherein the elastic element is connected to the first mounting plate, and the locking element is connected to the second mounting plate, and both the elastic element and the locking element are located between the first mounting plate and the second mounting plate. The pressure seat provided in the embodiment of the present application can realize automatic reset after the housing and the end cover are installed, and it is more convenient without manual reset.

[0010] In some embodiments, the elastic element includes: an elastic block; a second connecting shaft extending along the first direction, one end of the second connecting shaft being fixedly connected to the elastic block, and the other end of the second connecting shaft being movably connected to the first mounting plate; a second elastic element located between the elastic block and the first mounting plate, and the opposite ends of the second elastic element being in contact with the first mounting plate and the elastic block respectively; wherein, when the elastic force of the second elastic element is less than the first preset elastic force value, the elastic block and the locking element are offset. The elastic force of the second elastic element drives the elastic block to apply an impact force along the first direction to the second mounting plate, so that the shell and the end cover are pressed together under the pressure of the second mounting plate, that is, the elastic force of the second elastic element is converted into pressure on the battery shell, and the pressing effect is good.

[0011] In some embodiments, the locking element includes: a locking seat connected to the second mounting plate, the locking seat having a mounting groove; a third elastic element located in the mounting groove; a locking block, at least partially located in the mounting groove, the third elastic element abuts against the portion of the locking block located in the mounting groove, the end of the locking block away from the third elastic element can be movably extended out of the opening of the mounting groove, and the movable direction of the locking block is the same as the second direction; wherein, the end of the locking block away from the third elastic element has a first inclined surface, the first inclined surface faces the first mounting plate, the first inclined surface intersects with the second direction and is not perpendicular, and the end of the elastic block facing the locking element has a second inclined surface, and when the elastic force of the second elastic element is less than the first preset elastic force value, the first inclined surface fits with the second inclined surface. By setting the structure of the locking element and cooperating with the structure of the elastic block, the automatic resistance of the locking element to the elastic block can be achieved, which can reduce labor input and save labor costs.

[0012] In some embodiments, the first elastic element is configured to push the first mounting plate to move toward a side away from the second mounting plate when the elastic force of the first elastic element is greater than or equal to a second preset elastic force value. During the press-fitting process, since the first elastic element is compressed, the first elastic element will restore its deformation after the press-fitting is completed, and the first mounting plate will be pushed to move in a direction away from the second mounting plate under the action of the elastic force of the first elastic element, so that the pressure seat returns to its initial state, which is more convenient without manual reset.

[0013] In some embodiments, the locking block has a third inclined surface at one end away from the third elastic element, the third inclined surface is connected to the first inclined surface, the third inclined surface faces the second mounting plate, the third inclined surface intersects with the second direction and is not perpendicular, the first angle α between the first inclined surface and the second direction is less than the second angle β between the third inclined surface and the second direction, and the elastic block has a fourth inclined surface at one end facing the locking element, the fourth inclined surface is connected to the second inclined surface; when the first elastic element pushes the first mounting plate to move toward the side away from the second mounting plate, the fourth inclined surface moves in contact with the third inclined surface. The locking element provided in the embodiment of the present application can automatically return to the initial state after the press-fitting is completed, and will not prevent the pressure seat and the elastic element from automatically returning to the initial state, so that the entire pressure assembly can automatically return to the initial state, and it is more convenient without manual reset.

[0014] In some embodiments, the first angle α is greater than 5° and less than 35°, and / or the second angle β is greater than 40° and less than 80°. If the first angle α is too small, a large thrust is required to push the locking block, which may make the elastic block unable to push the locking block to move; if the first angle α is too large, a very small thrust can push the locking block to move, which will cause the elastic block to move toward the second mounting plate when the elastic force of the second elastic element on the elastic block is small, so that the second mounting plate applies less pressure to the battery shell, and the shell and the end cover may not be pressed together. Setting the first angle α in the above range can enable the elastic block to push the locking block to move, and the second mounting plate can apply enough pressure to the battery shell to press the shell and the end cover together. If the second angle β is too small, a large thrust is required to push the locking block, which may make the elastic block unable to push the locking block to move, and automatic reset cannot be achieved; if the second angle β is too large, it is inconvenient to manufacture. Setting the second angle β in the above range can achieve automatic reset and is convenient to manufacture.

A step is formed between the first sub-mounting groove and the second sub-mounting groove, and the protrusion of the locking block abuts against the step, so that the locking block will not be pushed out of the mounting groove by the third elastic element.

[0017] In some embodiments, the support mechanism has a guide rail extending along a first direction, and the sliding assembly includes: a sliding seat, which is slidably connected to the guide rail, and a pressure assembly connected to the sliding seat; a pressure handle, one end of which is hinged to the support mechanism; and a hinge rod, one end of which is hinged to the middle of the pressure handle, and the other end of which is hinged to the sliding seat.

[0018] In some embodiments, the sliding assembly further includes: a nitrogen spring, the opposite ends of the nitrogen spring are respectively hinged to the support mechanism and the sliding seat, and the nitrogen spring is configured to provide a force toward the pressure assembly to the sliding seat when the sliding seat moves toward the pressure assembly, and / or to provide a supporting force to the sliding seat when the sliding seat is in a set position. When the sliding seat moves toward the pressure assembly, the nitrogen spring provides a force toward the pressure assembly to the sliding seat, which is more labor-saving. When the sliding seat is in a set position, the nitrogen spring provides a supporting force to the sliding seat, which can ensure the stability of the sliding seat.

[0019] In some embodiments, the sliding assembly further includes: a buffer, connected to the support mechanism, and the buffer is located on opposite sides of the sliding seat along the first direction. The sliding seat will contact and abut against the buffer during the movement along the first direction X.

Figure 1The battery housing includes a shell 100 and an end cover 200. The shell 100 has a housing cavity 101, and a battery cell can be placed in the housing cavity 101. The end cover 200 refers to a component that covers the opening of the housing cavity 101 of the shell 100 to isolate the internal environment of the battery from the external environment. Without limitation, the shape of the end cover 200 can be adapted to the shape of the shell 100 to match the shell 100. Optionally, the end cover 200 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cover 200 is not easily deformed when it is squeezed and collided, so that the battery can have a higher structural strength and the safety performance can also be improved. Functional components such as poles 201 can be provided on the end cover 200. The pole 201 can be used to electrically connect with the battery cell for outputting or inputting the electrical energy of the battery cell. In some embodiments, the end cover 200 can also be provided with a pressure relief mechanism 202 for releasing the internal pressure when the internal pressure or temperature of the battery cell reaches a threshold.

[0073] The present application embodiment provides a battery housing installation device, Figure 2 This is a schematic diagram of the structure of a battery casing installation device according to some embodiments of the present application. Figure 3 This is a left side view of the battery housing installation device of some embodiments of the present application. Figure 2 and Figure 3 The battery housing installation device includes a support mechanism 10, a base mechanism 20 and a press-fitting mechanism 30. The base mechanism 20 and the press-fitting mechanism 30 are both connected to the support mechanism 10, and the base mechanism 20 is configured to place the end cap 200 and the shell 100, and the end cap 200 covers the opening of the shell 100. When the battery housing is located on the base mechanism 20, the press-fitting mechanism 30 and the base mechanism 20 are located on opposite sides of the battery housing along the first direction X, and the press-fitting mechanism 30 is configured to provide pressure to the end cap 200 toward the shell 100 or to provide pressure to the shell 100 toward the end cap 200 so that the end cap 200 is connected to the shell 100.

[0074] In the embodiment of the present application, the support mechanism 10 provides support for the base mechanism 20 and the press-fitting mechanism 30 to ensure the stability of the base mechanism 20 and the press-fitting mechanism 30 during use.

[0075] Exemplarily, the support mechanism 10 may be a support frame or a support table.

[0076] In the drawings of the embodiments of the present application, the end cover 200 is blocked by the base mechanism 20 and is not shown. The positional relationship between the end cover 200 and the housing 100 is shown in FIG. Figure 1 .

[0077] The end cap 200 and the housing 100 are interference fit, see Figure 1 The end cover 200 has a circle of end cover protrusions 203, which face the opening of the shell 100. The size of the end cover protrusions 203 is slightly larger than the size of the opening of the shell 100. The end cover protrusions 203 enter the accommodating cavity 101 under the action of pressure, thereby achieving an interference fit between the end cover 200 and the shell 100.

[0078] In the embodiment of the present application, the base mechanism 20 is used to place the end cap 200 and the housing 100 to ensure the stability of the end cap 200 and the housing 100 during use. The end cap 200 covers the opening of the housing 100, and the end cap 200 and the housing 100 can be assembled together when pressure is applied to the end cap 200 or the housing 100.

[0079] Illustratively, the base mechanism 20 may include a support plate.

[0080] In an embodiment of the present application, the press-fitting mechanism 30 is used to provide pressure, wherein the end cap 200 can be located between the shell 100 and the press-fitting mechanism 30, and the press-fitting mechanism 30 provides pressure on the end cap 200 toward the shell 100 during the press-fitting process; or the shell 100 is located between the end cap 200 and the press-fitting mechanism 30, and the press-fitting mechanism 30 provides pressure on the shell 100 toward the end cap 200 during the press-fitting process.

[0081] Exemplarily, the press-fitting mechanism 30 may include a driving assembly and a driving plate, and the driving assembly may push the driving plate to move so that the press-fitting mechanism 30 can provide pressure. For example, the driving assembly may include a cylinder or a motor.

[0082] In an embodiment of the present application, the end cap 200 and the shell 100 are arranged along a first direction X, the press-fitting mechanism 30 and the base mechanism 20 are located on opposite sides of the battery housing along the first direction X, and the pressure provided by the press-fitting mechanism 30 to the end cap 200 or the shell 100 has a component along the first direction X, that is, the end cap 200 or the shell 100 moves toward the base mechanism 20, and due to the obstruction of the base mechanism 20, the press-fitting mechanism 30 can provide pressure to the end cap 200 or the shell 100.

[0083] When using the battery casing installation device provided in the embodiment of the present application, the end cap 200 and the shell 100 are placed on the base mechanism 20, and the end cap 200 covers the opening of the shell 100, and then the pressing mechanism 30 is controlled to provide pressure to the end cap 200 toward the shell 100 or to provide pressure to the shell 100 toward the end cap 200, so that the end cap 200 is connected to the shell 100, and mechanical pressing is achieved. The pressing speed is fast, the efficiency of the battery casing installation is improved, and the production efficiency of the battery is improved.

[0084] According to some embodiments of the present application, see Figure 2 and Figure 3 The press-fitting mechanism 30 includes a sliding assembly 31 and a pressure assembly 32. The sliding assembly 31 is slidably connected to the support mechanism 10, and the slidable direction of the sliding assembly 31 is the same as the first direction X. The pressure assembly 32 is connected to the sliding assembly 31, and the pressure assembly 32 is located between the sliding assembly 31 and the base mechanism 20. The sliding assembly 31 is configured to push the pressure assembly 32 to apply pressure to the battery housing under the action of pressure.

[0085] In an embodiment of the present application, a slide rail may be provided on the support mechanism 10, and a slider may be provided on the sliding assembly 31; or a slider may be provided on the support mechanism 10, and a slide rail may be provided on the sliding assembly 31, the slide rail extends along the first direction X, and the slide rail is slidably connected to the slider, thereby realizing a slidable connection between the sliding assembly 31 and the support mechanism 10.

[0086] In the embodiment of the present application, since the sliding direction of the sliding component 31 is the same as the first direction X, when the sliding component 31 drives the pressure component 32 to move along the first direction X, the pressure component 32 can provide pressure to the battery housing.

[0087] In an embodiment of the present application, when placing the battery casing, the battery casing can be placed closer to the pressure assembly 32, so that when the sliding assembly 31 subsequently drives the pressure assembly 32 to move, the pressure assembly 32 only needs to move a short distance to contact the battery casing and provide pressure to the battery casing.

[0088] In the embodiment of the present application, the sliding of the sliding component 31 can be controlled to drive the pressure component 32 to move, so that the pressure component 32 can apply pressure to the battery housing, which is more convenient.

[0089] According to some embodiments of the present application, Figure 4 This is a schematic diagram of the structure of the pressure assembly of some embodiments of the present application. Figure 5 This is a left side view of a pressure assembly according to some embodiments of the present application. Figure 6 For this application Figure 5 Cross-section view of the AA plane. Figures 4 to 6 The pressure assembly 32 includes a pressure seat 321, an elastic element 322 and a locking element 323. Figures 2 to 6 The pressure seat 321 is connected to the sliding assembly 31, the elastic element 322 is movably elastically connected to the pressure seat 321, the movable direction of the elastic element 322 is the same as the first direction X, and the locking element 323 is connected to the pressure seat 321. Wherein, when the elastic force of the elastic element 322 is less than the first preset elastic force value, the end of the elastic element 322 facing the base mechanism 20 abuts against the locking element 323, and when the elastic force of the elastic element 322 is greater than or equal to the first preset elastic force value, the locking element 323 moves along the second direction Y, so that the elastic element 322 moves toward the base mechanism 20 along the first direction X and provides pressure to the battery housing, and the first direction X intersects with the second direction Y.

[0090] In the embodiment of the present application, both the elastic element 322 and the locking element 323 are connected to the pressure seat 321, and the pressure seat 321 provides support for the elastic element 322 and the locking element 323. Exemplarily, the pressure seat 321 may be a support frame or a support table.

[0091] In the embodiment of the present application, the pressure seat 321 is connected to the sliding assembly 31 , and can drive the pressure seat 321 to move along the first direction X when the sliding assembly 31 slides.

[0092] In the embodiment of the present application, when the press-fitting is not performed, the elastic force of the elastic element 322 is relatively small, and at this time, one end of the elastic element 322 facing the base mechanism 20 abuts against the locking element 323 . When the sliding assembly 31 drives the pressure seat 321 to move toward the battery shell along the first direction X, the pressure seat 321 will also drive the elastic element 322 to move toward the battery shell. Since the end of the elastic element 322 toward the base mechanism 20 is against the locking element 323, the end of the elastic element 322 away from the base mechanism 20 moves toward the battery shell, so that the compression of the elastic element 322 increases, and the elastic force of the elastic element 322 increases. When the elastic force of the elastic element 322 increases to be greater than or equal to the first preset elastic force value, the locking element 323 moves along the second direction Y, that is, the locking element 323 is released from resisting the end of the elastic element 322 toward the base mechanism 20. Under the action of the elastic force, the locking element 323 will quickly move toward the battery shell and apply an impact force along the first direction X to the battery shell, so that the shell 100 and the end cover 200 are pressed together.

[0093] In the related art, the battery shell is manually pressed by the staff. During the pressing process, the pressure applied by the staff to the battery shell cannot be guaranteed to be consistent, resulting in a poor pressing effect. In the embodiment of the present application, through the pressure seat 321, the elastic element 322 and the locking element 323, the elastic element 322 applies an impact force along the first direction X to the battery shell under the action of the elastic force, so that the shell 100 and the end cover 200 are assembled. That is, the pressure applied to the battery shell comes from the elastic force of the elastic element 322, and the elastic force of the elastic element 322 is certain. During the pressing process, the pressure applied by the pressure assembly 32 to the battery shell is less different, and the pressing effect is better and the uniformity is better.

[0094] According to some embodiments of the present application, see Figures 4 to 6 The pressure seat 321 includes a first mounting plate 3211, a second mounting plate 3212, a first connecting shaft 3213 and a first elastic element 3214, and the second mounting plate 3212 is stacked with the first mounting plate 3211. Figures 2 to 6, the first mounting plate 3211 is connected to the sliding assembly 31, the second mounting plate 3212 is located on the side of the first mounting plate 3211 away from the sliding assembly 31, the first connecting shaft 3213 extends along the first direction X, one end of the first connecting shaft 3213 is fixedly connected to the second mounting plate 3212, and the other end of the first connecting shaft 3213 is movably connected to the first mounting plate 3211, the first elastic element 3214 is sleeved on the first connecting shaft 3213, and the opposite ends of the first elastic element 3214 are respectively against the first mounting plate 3211 and the second mounting plate 3212. Among them, the elastic element 322 is connected to the first mounting plate 3211, the locking element 323 is connected to the second mounting plate 3212, and the elastic element 322 and the locking element 323 are both located between the first mounting plate 3211 and the second mounting plate 3212.

[0095] In an embodiment of the present application, the first mounting plate 3211, the second mounting plate 3212, the first connecting shaft 3213 and the first elastic element 3214 form a frame-like structure, and the opposite ends of the first elastic element 3214 are respectively against the first mounting plate 3211 and the second mounting plate 3212. Under the action of the elastic force of the first elastic element 3214, a space is created between the first mounting plate 3211 and the second mounting plate 3212, and the elastic element 322 and the locking element 323 are both located in the space.

[0096] In an embodiment of the present application, since one end of the first connecting shaft 3213 is fixedly connected to the second mounting plate 3212, the other end of the first connecting shaft 3213 is movably connected to the first mounting plate 3211, and the first connecting shaft 3213 extends along the first direction X, the first mounting plate 3211 can move along the first direction X.

[0097] In the embodiment of the present application, when the press-fitting is not performed, the base mechanism 20 and the press-fitting mechanism 30 can be adjusted so that the second mounting plate 3212 contacts the battery housing. When the sliding assembly 31 moves toward the battery housing along the first direction X, the first mounting plate 3211 moves toward the second mounting plate 3212 following the sliding assembly 31. Since the second mounting plate 3212 is blocked by the battery housing and cannot move, the first elastic element 3214 is compressed. The elastic element 322 will follow the first mounting plate 3211 to move toward the second mounting plate 3212. The locking element 323 is connected to the second mounting plate 3212 and cannot move either, so that the elastic element 322 is compressed and the elastic force of the elastic element 322 increases. When the elastic force of the elastic element 322 increases to be greater than or equal to the first preset elastic force value, the locking element 323 moves along the second direction Y. The elastic element 322 will quickly move toward the second mounting plate 3212 under the action of the elastic force and exert an impact force along the first direction X on the second mounting plate 3212, so that the second mounting plate 3212 presses the battery casing, thereby pressing the shell 100 and the end cover 200 together. At the same time, since the first elastic element 3214 is compressed, the first elastic element 3214 will restore its deformation, and under the action of the elastic force of the first elastic element 3214, the first mounting plate 3211 is pushed to move away from the second mounting plate 3212. The first mounting plate 3211 also drives the elastic element 322 to move, so that the pressure seat 321 and the elastic element 322 return to their initial state, which is more convenient without manual reset.

[0098] See also Figures 4 to 6 The pressure seat 321 also includes a first shaft end baffle 3215, which passes through the through hole on the first mounting plate 3211 and is fixedly connected to the first mounting plate 3211. The first connecting shaft 3213 passes through the first shaft end baffle 3215. During the movement of the first mounting plate 3211, the friction between the first mounting plate 3211 and the first connecting shaft 3213 is reduced, the possibility of damage to the first mounting plate 3211 is reduced, and the stability of the battery housing mounting device is improved. Exemplarily, the end of the first connecting shaft 3213 away from the second mounting plate 3212 has a circle of protrusions, which are against the first shaft end baffle 3215, so that the first connecting shaft 3213 and the first mounting plate 3211 will not be separated.

[0099] In some embodiments of the present application, the first elastic element 3214 may be a spring, a torsion spring, or other elastic components.

[0100] See also Figure 6The first mounting plate 3211 has a first mounting hole 32111 on one side facing the sliding component 31, and the sliding component 31 has a threaded hole on one side facing the first mounting plate 3211. Bolts pass through the first mounting hole 32111 and are connected to the threaded hole to achieve connection between the first mounting plate 3211 and the sliding component 31.

[0101] The pressure seat 321 provided in the embodiment of the present application can be automatically reset after the housing 100 and the end cover 200 are installed, which is more convenient without the need for manual reset.

[0102] According to some embodiments of the present application, see Figures 4 to 6 The elastic element 322 includes an elastic block 3221, a second connecting shaft 3222, and a second elastic element 3223. The second connecting shaft 3222 extends along the first direction X, one end of the second connecting shaft 3222 is fixedly connected to the elastic block 3221, and the other end of the second connecting shaft 3222 is movably connected to the first mounting plate 3211. The second elastic element 3223 is located between the elastic block 3221 and the first mounting plate 3211, and the opposite ends of the second elastic element 3223 are in contact with the first mounting plate 3211 and the elastic block 3221, respectively. In the case where the elastic force of the second elastic element 3223 is less than the first preset elastic force value, the elastic block 3221 and the locking element 323 are offset.

[0103] In an embodiment of the present application, when the sliding assembly 31 moves toward the battery housing along the first direction X, the first mounting plate 3211 will follow the sliding assembly 31 to move toward the second mounting plate 3212. Since the locking element 323 is connected to the second mounting plate 3212, the locking element 323 cannot move, and at this time the elastic block 3221 is against the locking element 323, and the elastic block 3221 cannot move either, so that the second elastic element 3223 between the first mounting plate 3211 and the elastic block 3221 is compressed, and the elastic force of the second elastic element 3223 increases. When the elastic force of the second elastic element 3223 increases to be greater than or equal to the first preset elastic force value, the locking element 323 moves along the second direction Y, and the elastic block 3221 will quickly move toward the second mounting plate 3212 under the action of the elastic force of the second elastic element 3223, and exert an impact force along the first direction X on the second mounting plate 3212, so that the second mounting plate 3212 applies pressure to the battery housing to press the shell 100 and the end cover 200 together.

[0104] When the elastic block 3221 moves rapidly toward the battery casing under the action of the elastic force, it will also drive the second connecting shaft 3222 to move toward the battery casing. Since the first mounting plate 3211 moves a distance toward the second mounting plate 3212, in the second direction Y, the second connecting shaft 3222 is at a distance from the first mounting plate 3211. When the elastic block 3221 moves toward the second mounting plate 3212, the first mounting plate 3211 will not block the second connecting shaft 3222 from moving toward the second mounting plate 3212, so that more elastic force is applied to the second mounting plate 3212, and the second mounting plate 3212 can provide greater pressure to the shell 100 and the end cover 200.

[0105] See also Figures 4 to 6 The elastic element 322 also includes a second shaft end baffle 3224, which passes through the through hole on the first mounting plate 3211 and is fixedly connected to the first mounting plate 3211. The second connecting shaft 3222 passes through the second shaft end baffle 3224. During the movement of the first mounting plate 3211, the friction between the first mounting plate 3211 and the second connecting shaft 3222 is reduced, the possibility of damage to the first mounting plate 3211 is reduced, and the stability of the battery housing mounting device is improved. Exemplarily, the end of the second connecting shaft 3222 away from the second mounting plate 3212 has a circle of protrusions, which abut against the second shaft end baffle 3224, so that the second connecting shaft 3222 and the first mounting plate 3211 will not be separated.

[0106] In some embodiments of the present application, the second elastic element 3223 may be a spring, a torsion spring, or other elastic components.

[0107] See also Figure 6 The first mounting plate 3211 has a first groove 32112 on one side facing the elastic block 3221, and the elastic block 3221 has a second groove 32213 on one side facing the first mounting plate 3211. The opposite ends of the second elastic element 3223 are respectively located in the first groove 32112 and the second groove 32213 to improve the stability of the second elastic element 3223.

[0108] In an embodiment of the present application, the elastic force of the second elastic element 3223 is used to drive the elastic block 3221 to apply an impact force along the first direction X to the second mounting plate 3212, so that the shell 100 and the end cover 200 are pressed together under the pressure of the second mounting plate 3212, that is, the elastic force of the second elastic element 3223 is converted into pressure on the battery shell, and the pressing effect is good.

[0109] According to some embodiments of the present application, Figure 7 This is a schematic diagram of the structure of the locking element of some embodiments of the present application. Figure 8 This is a partial cross-sectional view of a locking element according to some embodiments of the present application. Fig. 9 For this application Figure 8 Cross-section view of the BB plane. Figures 7 to 9 The locking element 323 includes a locking seat 3231, a third elastic element 3232 and a locking block 3233. Figures 4 to 9 The locking seat 3231 is connected to the second mounting plate 3212, and the locking seat 3231 has a mounting groove 32311; the third elastic element 3232 is located in the mounting groove 32311; at least a portion of the locking block 3233 is located in the mounting groove 32311, the third elastic element 3232 is abutted against a portion of the locking block 3233 located in the mounting groove 32311, and one end of the locking block 3233 away from the third elastic element 3232 is movably extended out of the opening of the mounting groove 32311, and the movable direction of the locking block 3233 is the same as the second direction Y. Among them, the locking block 3233 has a first inclined surface 32331 at one end away from the third elastic element 3232, the first inclined surface 32331 faces the first mounting plate 3211, the first inclined surface 32331 intersects with the second direction Y and is not perpendicular, and the elastic block 3221 has a second inclined surface 32211 at one end facing the locking element 323. When the elastic force of the second elastic element 3223 is less than the first preset elastic force value, the first inclined surface 32331 fits with the second inclined surface 32211.

[0110] In the embodiment of the present application, the locking seat 3231 is used to install the third elastic element 3232 and the locking block 3233 to ensure the stability of the third elastic element 3232 and the locking block 3233 during operation.

[0111] In an embodiment of the present application, the locking seat 3231 and the second mounting plate 3212 may be connected by bolts, or the locking seat 3231 and the second mounting plate 3212 may be bonded.

[0112] In the embodiment of the present application, the locking block 3233 can move along the depth direction of the installation groove 32311, and during the movement of the locking block 3233, the third elastic element 3232 is compressed or stretched.

[0113] In some embodiments of the present application, the first direction X and the second direction Y may be perpendicular to each other.

[0114] In the embodiment of the present application, the third elastic element 3232 exerts an elastic force on the locking block 3233 along the second direction Y, and the second elastic element 3223 exerts an elastic force on the elastic force block 3221 along the first direction X. Since the first inclined surface 32331 intersects with the second direction Y and is not perpendicular to it, the elastic force of the third elastic element 3232 on the locking block 3233 has a component along the second direction Y, and the elastic force of the second elastic element 3223 on the elastic force block 3221 also has a component along the second direction Y. The components of the two components are balanced in the initial state, so that the first inclined surface 32331 and the second inclined surface 32211 are offset. As the second elastic element 3223 is squeezed, the elastic force of the second elastic element 3223 on the elastic block 3221 increases, and the component of the elastic force of the second elastic element 3223 on the elastic block 3221 along the second direction Y also increases. When the elastic force of the second elastic element 3223 on the elastic block 3221 increases to be greater than or equal to the first preset elastic force value, the elastic block 3221 pushes the locking block 3233 to move along the second direction Y, thereby releasing the resistance of the locking block 3233 to the elastic block 3221.

[0115] In the embodiment of the present application, by setting the structure of the locking element 323 and cooperating with the structure of the elastic block 3221, the locking element 323 can automatically resist the elastic block 3221, which can reduce manual input and save labor costs.

[0116] In other embodiments of the present application, the locking element 323 can also be moved along the second direction Y through other structures. For example, the locking element 323 includes a driving member and a stopper. The driving member has a telescopic shaft extending along the second direction Y. The stopper is connected to the telescopic shaft. A sensor is provided on the stopper, and the sensor is used to detect the extrusion force exerted on the stopper. In the initial state, the stopper and the elastic block 3221 are against each other, and the extrusion force detected by the sensor is small. As the elastic force of the elastic element 322 increases, the extrusion force of the elastic block 3221 on the stopper increases. When the extrusion force detected by the sensor is greater than the preset pressure value, the stopper is controlled to move along the second direction, and the stopper is released from resisting the elastic block 3221.

[0117] According to some embodiments of the present application, the first elastic element 3214 is configured to push the first mounting plate 3211 to move toward a side away from the second mounting plate 3212 when the elastic force of the first elastic element 3214 is greater than or equal to a second preset elastic force value.

[0118] In an embodiment of the present application, during the press-fitting process, since the first elastic element 3214 is compressed, the first elastic element 3214 will restore its deformation after the press-fitting is completed. Under the action of the elastic force of the first elastic element 3214, the first mounting plate 3211 is pushed to move away from the second mounting plate 3212, so that the pressure seat 321 returns to its initial state, which is more convenient without the need for manual resetting.

[0119] According to some embodiments of the present application, Figure 6 and Fig. 9 The end of the locking block 3233 away from the third elastic element 3232 has a third inclined surface 32332, the third inclined surface 32332 is connected to the first inclined surface 32331, the third inclined surface 32332 faces the second mounting plate 3212, the third inclined surface 32332 intersects with the second direction Y and is not perpendicular, the first angle α between the first inclined surface 32331 and the second direction Y is smaller than the second angle β between the third inclined surface 32332 and the second direction Y, and the end of the elastic block 3221 facing the locking element 323 has a fourth inclined surface 32212, the fourth inclined surface 32212 is connected to the second inclined surface 32211. When the first elastic element 3214 pushes the first mounting plate 3211 to move toward the side away from the second mounting plate 3212, the fourth inclined surface 32212 moves in contact with the third inclined surface 32332.

[0120] In the embodiment of the present application, the third inclined surface 32332 and the first inclined surface 32331 may be connected by an arc surface.

[0121] Since the first angle α between the first inclined surface 32331 and the second direction Y is smaller than the second angle β between the third inclined surface 32332 and the second direction Y, when the first inclined surface 32331 is subjected to a force F1 perpendicular to the first inclined surface 32331 and the third inclined surface 32332 is subjected to a force F2 perpendicular to the first inclined surface 32331, and F1 is equal to F2, the component of F2 along the second direction Y will be greater than the component of F1 along the second direction Y.

[0122] In the embodiment of the present application, after the press-fitting is completed, the locking block 3233 will return to its initial state under the elastic force of the third elastic element 3232, and the first elastic element 3214 will restore its deformation, and under the elastic force of the first elastic element 3214, the first mounting plate 3211 will be pushed to move in the direction away from the second mounting plate 3212, and the first mounting plate 3211 will drive the elastic block 3221 to move. At this time, the fourth inclined surface 32212 is in contact with the third inclined surface 32332. Since the second angle β between the third inclined surface 32332 and the second direction Y is larger, the elastic block 3221 provides a smaller thrust to the locking block 3233, which will push the locking block 3233 to move. After the elastic block 3221 moves to the initial position, the locking block 3233 returns to its initial state again, that is, the entire pressure assembly 32 can automatically return to its initial state, which is more convenient without manual reset.

[0123] The locking element 323 provided in the embodiment of the present application can automatically return to its initial state after the press-fitting is completed, and will not prevent the pressure seat 321 and the elastic element 322 from automatically returning to their initial state, so that the entire pressure assembly 32 can automatically return to its initial state without manual resetting, which is more convenient.

[0124] According to some embodiments of the present application, the first angle α is greater than 5° and less than 35°, and / or the second angle β is greater than 40° and less than 80°.

[0125] In an embodiment of the present application, the first angle α is greater than 5° and less than 35°, and / or the second angle β is greater than 40° and less than 80°, which can be characterized as: the first angle α is greater than 5° and less than 35°; or the second angle β is greater than 40° and less than 80°; or the first angle α is greater than 5° and less than 35°, and the second angle β is greater than 40° and less than 80°.

[0126] Exemplarily, the first angle α may be equal to 30°, and the second angle β may be equal to 60°.

[0127] In the embodiment of the present application, if the first angle α is too small, a large thrust is required to push the locking block 3233, which may make the elastic block 3221 unable to push the locking block 3233 to move; if the first angle α is too large, a small thrust can push the locking block 3233 to move, which will cause the elastic force of the second elastic element 3223 on the elastic block 3221 to be small, and the elastic block 3221 will move toward the second mounting plate 3212, so that the second mounting plate 3212 applies less pressure to the battery shell, and the shell 100 and the end cover 200 may not be pressed together. Setting the first angle α in the above range can enable the elastic block 3221 to push the locking block 3233 to move, and the second mounting plate 3212 can apply enough pressure to the battery shell to press the shell 100 and the end cover 200 together. If the second angle β is too small, a large thrust is required to push the locking block 3233, which may make the elastic block 3221 unable to push the locking block 3233 to move, and automatic reset cannot be achieved; if the second angle β is too large, it is inconvenient to manufacture. Setting the second angle β in the above range can achieve automatic reset and is convenient for manufacturing.

[0128] According to some embodiments of the present application, see Fig. 9The locking seat 3231 has a threaded hole 32312, which passes through the bottom surface of the mounting groove 32311 along the second direction Y and is connected to the mounting groove 32311. The locking element 323 also includes a push block 3234 and an adjusting bolt 3235. The push block 3234 is located in the mounting groove 32311. The opposite ends of the third elastic element 3232 are respectively in contact with the locking block 3233 and the push block 3234. The adjusting bolt 3235 is threadedly connected with the threaded hole 32312 and passes through the threaded hole 32312 to contact the push block 3234.

[0129] In the embodiment of the present application, one end of the third elastic element 3232 that contacts the pushing block 3234 can be sleeved on the pushing block 3234 .

[0130] In the embodiment of the present application, the greater the first preset elastic force value, the greater the impact force of the elastic block 3221 on the second mounting plate 3212, and the greater the pressure applied by the second mounting plate 3212 to the battery housing. The third elastic element 3232 has an elastic force on the locking block 3233 along the second direction Y. When the component of the elastic force of the second elastic element 3223 on the elastic block 3221 along the second direction Y is greater than the component of the elastic force of the third elastic element 3232 on the locking block 3233 along the second direction Y, the locking block 3233 can be pushed to move. The first preset elastic force value can be adjusted by adjusting the elastic force of the third elastic element 3232 on the locking block 3233.

[0131] In some embodiments of the present application, the third elastic element 3232 may be a spring, a torsion spring, or other elastic components.

[0132] In an embodiment of the present application, the position of the push block 3234 in the mounting groove 32311 can be adjusted by screwing the adjusting bolt 3235, thereby adjusting the deformation of the third elastic element 3232, and thereby adjusting the elastic force of the third elastic element 3232 on the locking block 3233, that is, adjusting the first preset elastic force value, thereby adjusting the pressure applied by the second mounting plate 3212 to the battery casing.

[0133] See also Figure 8 and Fig. 9 The locking element 323 also includes a locking nut 3236, which is located outside the mounting groove 32311 and is threadedly connected to the adjusting bolt 3235. The locking nut 3236 abuts against the outer side wall of the locking seat 3231 to improve the stability of the adjusting bolt 3235.

[0134] According to some embodiments of the present application, see Figure 8The mounting groove 32311 includes a first sub-mounting groove 32313 and a second sub-mounting groove 32314 which are arranged along the second direction Y and connected to each other. The orthographic projection of the first sub-mounting groove 32313 on the first plane is located within the orthographic projection of the second sub-mounting groove 32314 on the first plane and do not overlap. The first plane is perpendicular to the second direction Y. A step is formed between the first sub-mounting groove 32313 and the second sub-mounting groove 32314. The end of the locking block 3233 facing the third elastic element 3232 has a protrusion 32333 facing the outside of the locking block 3233, and the protrusion 32333 is against the step.

[0135] In the embodiment of the present invention, the first sub-mounting groove 32313 is close to the opening of the mounting groove 32311 , and the second sub-mounting groove 32314 is close to the bottom surface of the mounting groove 32311 .

[0136] The orthographic projection of the first sub-mounting groove 32313 on the first plane indicates that the projection lines passing through the first sub-mounting groove 32313 are parallel to each other, and the projection lines are perpendicular to the first surface.

[0137] In the embodiment of the present application, a step is formed between the first sub-mounting groove 32313 and the second sub-mounting groove 32314 , and the protrusion 32333 of the locking block 3233 abuts against the step, so that the locking block 3233 will not be pushed out of the mounting groove 32311 by the third elastic element 3232 .

[0138] Combination Figure 7 and Fig. 9 The locking seat 3231 includes a locking shell 32315 and a locking top cover 32316. The mounting groove 32311 is located in the locking shell 32315. After the third elastic element 3232, the locking block 3233 and the adjusting push block 3234 are installed into the mounting groove 32311, the locking top cover 32316 covers the locking shell 32315 and is connected to the locking shell 32315 to realize the installation of the locking seat 3231.

[0139] According to some embodiments of the present application, see Figure 2 The support mechanism 10 has a guide rail 11 extending along a first direction X. Fig.10 This is a schematic diagram of the structure of the sliding assembly of some embodiments of the present application. Fig.11 This is a left side view of the sliding assembly of some embodiments of the present application. Figure 2 , Figure 3 , Fig.10 and Fig.11The sliding assembly 31 includes a sliding seat 311, a pressure handle 312 and a hinged rod 313. The sliding seat 311 is slidably connected to the guide rail 11, the pressure assembly 32 is connected to the sliding seat 311, and one end of the pressure handle 312 is hinged to the support mechanism 10. One end of the hinged rod 313 is hinged to the middle of the pressure handle 312, and the other end of the hinged rod 313 is hinged to the sliding seat 311.

[0140] In the embodiment of the present application, the shape of the sliding seat 311 can be set according to requirements and is not limited to the structure shown in the drawings of the present application.

[0141] In the embodiment of the present application, the pressure handle 312 can be operated to move the sliding seat 311 along the guide rail 11 , thereby enabling the sliding seat 311 to drive the pressure assembly 32 to move.

[0142] According to some embodiments of the present application, Figure 2 , Figure 3 , Fig.10 and Fig.11 The sliding assembly 31 further includes a nitrogen spring 314. The opposite ends of the nitrogen spring 314 are respectively hinged to the support mechanism 10 and the sliding seat 311, and the nitrogen spring 314 is configured to provide a force toward the pressure assembly 32 to the sliding seat 311 when the sliding seat 311 moves toward the pressure assembly 32, and / or provide a supporting force to the sliding seat 311 when the sliding seat 311 is in a set position.

[0143] In the embodiment of the present application, the number of nitrogen springs 314 is not limited and can be set according to requirements.

[0144] In an embodiment of the present application, the nitrogen spring 314 can realize at least one of the following functions: providing a force toward the pressure assembly 32 to the sliding seat 311 when the sliding seat 311 moves toward the pressure assembly 32; and providing a supporting force to the sliding seat 311 when the sliding seat 311 is in a set position.

[0145] Exemplarily, the set position can be the position of the sliding seat 311 when the pressure assembly 32 is not in contact with the battery housing and the base assembly. It can also be understood that the position of the sliding seat 311 when the battery housing mounting device is not in use.

[0146] In the embodiment of the present application, the nitrogen spring 314 provides a force to the sliding seat 311 toward the pressure assembly 32 when the sliding seat 311 moves toward the pressure assembly 32, which is more labor-saving. When the sliding seat 311 is in a set position, the nitrogen spring 314 provides a supporting force to the sliding seat 311, which can ensure the stability of the sliding seat 311.

[0147] According to some embodiments of the present application, see Fig.10and Fig.11 The sliding assembly 31 also includes a buffer 315, combined with Figure 2 , Figure 3 , Fig.10 and Fig.11 The buffer member 315 is connected to the supporting mechanism 10 , and the buffer member 315 is located on two opposite sides of the sliding seat 311 along the first direction X.

[0148] In the embodiment of the present application, the buffer members 315 located on both sides of the sliding seat 311 along the first direction X can be connected to the support mechanism 10 through the buffer mounting seats 316. The shapes of the two buffer mounting seats 316 can be the same or different.

[0149] For example, in combination Figure 3 and Fig.11 The buffer mounting seat 316 located above the sliding seat 311 along the first direction X has more installation space, and the buffer mounting seat 316 can be set larger to improve the stability of the buffer mounting seat 316; the buffer mounting seat 316 located below the sliding seat 311 along the first direction X has a smaller installation space, and the buffer mounting seat 316 can be set smaller to avoid other components.

[0150] In the embodiment of the present application, the sliding seat 311 contacts and abuts against the buffer 315 during the movement along the first direction X. The buffer 315 can limit the range of movement of the sliding seat 311 to prevent the sliding seat 311 from moving too much and colliding with other components. At the same time, the buffer 315 can reduce the collision between the sliding seat 311 and the buffer 315 during the sliding process, thereby improving the stability of the sliding seat 311.

[0151] Exemplarily, the buffer 315 may include a spring.

[0152] See also Figures 3 to 5 The pressure assembly 32 also includes a buffer baffle 324, which is connected to the first mounting plate 3211. The buffer baffle 324 corresponds to the buffer member 315 located below the sliding seat 311 along the first direction X, which can reduce the collision between the buffer member 315 and the pressure assembly 32 and improve the stability of the pressure assembly 32.

When a different battery cell needs to be replaced, it is only necessary to disassemble the first sub-base plate 222 and the first base plate 21, and it is more convenient not to disassemble the entire base mechanism 20.

[0160] According to some embodiments of the present application, see Fig.15 The base mechanism 20 further includes a fourth elastic element 23 and a round pin 24.
