[0035] See also Figures 1 to 7 The embodiment of the utility model provides a stationary device for soft-pack battery cells; comprising: a support frame 3; an inclined carrier plate 1, arranged on the support frame 3 and / or below the support frame 3, for stationary soft-pack battery cells, wherein the surface for supporting the battery cells is an inclined surface A inclined relative to the horizontal plane; a limiter 2, arranged at the bottom end of the inclined carrier plate 1, and the working surface of the limiter 2 is perpendicular to the inclined surface A, for limiting the movement of the soft-pack battery cells; a pressurizing component 4, the working surface of the pressurizing component 4 is perpendicular to the inclined surface A of the inclined carrier plate 1 and is arranged at the top of the inclined carrier plate 1, for squeezing the soft-pack battery cells along the inclined surface A.

[0036] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, it should be noted that the support frame 3, as the basic structure of the entire stationary device, plays the role of fixing and supporting other components to ensure the stability and structural integrity of the entire device. In this application, it is used to fix and support the inclined load plate 1, the limiter 2 and the pressure component 4. Figure 3As shown, the inclined carrier plate 1 can be arranged on the support frame 3 or below the support frame 3. It can be understood that the inclined carrier plate 1 is arranged below the support frame 3 and can be placed on the horizontal ground. In order to achieve the purpose of placing as many battery cells as possible, in the embodiment of the present application, it is preferred to place the inclined carrier plate 1 on the support frame 3 and on the horizontal ground below the support frame 3 at the same time. The limiter 2 is installed at the bottom end of the inclined carrier plate 1, and its working surface is perpendicular to the inclined surface A of the inclined carrier plate 1. Its main function is to limit the movement of the soft-pack battery cell on the inclined carrier plate 1, prevent the battery cell from slipping or shifting due to external factors during the static process, and ensure the stability and safety during the static process. The working surface of the pressurizing component 4 is perpendicular to the inclined surface A of the inclined carrier plate 1, and is installed on the top of the inclined carrier plate 1. Its main function is to squeeze the soft-pack battery cell along the inclined surface A. Through the squeezing of the soft-pack battery cell by the pressurizing component 4, the various components inside the soft-pack battery cell are more closely fitted, thereby improving the energy density and performance of the battery cell. At the same time, pressurization can also reduce the gaps inside the battery cell to prevent problems such as expansion or deformation during subsequent use.

[0037] In the above embodiment, the support frame 3 can be installed with the inclined carrier plate 1, and the surface of the inclined carrier plate 1 for carrying the battery cell is an inclined surface A inclined relative to the horizontal plane, which can be used to place the battery cell. In actual use, since the inclined carrier plate 1 is provided with an inclined surface A at an inclined angle to the horizontal plane on the horizontal plane, a stable triangular structure is formed with the horizontal plane, wherein the inclined surface A is the longest side of the triangular structure. The limiter 2 is placed at the bottom end of the inclined carrier plate 1, and the working surface of the limiter 2 is kept perpendicular to the inclined surface A. The limiter 2 is fixed to the support frame 3 by bolts to ensure that the limiter 2 and the inclined carrier plate 1 do not move. Since the limiter 2 is perpendicular to the inclined surface A, when placing the battery cell, the battery cell at the bottom end of the inclined carrier plate 1 has one side in contact with the limiter 2 and the other side in contact with the inclined surface A. The battery cells can be placed vertically relative to the inclined surface A. Since the working surface of the limiting member 2 is in contact with the battery cells located at the bottom end of the inclined carrier plate 1, it can limit the movement of the battery cells and ensure that the battery cells will not fall when they are stationary. Therefore, the battery cells can be placed on the inclined carrier plate 1. Compared with the prior art that uses a bottom plane to directly place the battery cells for stationary placement, a larger number of battery cells can be placed in the same space. In the process of large-scale production of battery cells, it is beneficial to expand the scale of battery cell stationary placement. The overall structure of the stationary device is simple, which is conducive to large-scale stationary placement of battery cells and has a lower cost than existing battery cell stationary devices.

[0038] like Figure 3 , Figure 4 As shown, in one embodiment, the support frame 30 includes multiple support rods 31 and multiple layers of horizontal supports 32; the multiple support rods 31 are arranged parallel to each other and are respectively vertically connected to the multiple layers of horizontal supports 32, and a placement surface is provided on the horizontal support 32 for placing the inclined carrier plate 1 and the limit member 2.

[0039] In the above embodiment, the support frame 3 includes a plurality of support rods 31 and a plurality of horizontal supports 32, wherein the support rods 31 are arranged parallel to each other and are respectively connected vertically to the plurality of horizontal supports 32. Specifically, a plurality of horizontal supports 32 are bolted to a plurality of adjacent support rods 31. After connection, a horizontal layer is formed between the horizontal supports 32. A placement surface is arranged on the horizontal layer for installing the inclined carrier 1. The inclined carrier 1 is installed on the plane of the placement surface, and then the stopper 2 is installed at the bottom end of the inclined carrier 1, and the working surface of the stopper 2 is kept perpendicular to the inclined surface A of the inclined carrier 1. Since the support rods 31 are vertically connected to the horizontal supports 32 and the support rods 31 are arranged parallel to each other, when the support rods 31 are placed on the ground, the support frame 3 formed by the vertical connection with the plurality of horizontal supports 32 can support the inclined carrier 1 placed on the placement surface forming the horizontal layer between the horizontal supports 32 and the battery cells placed on the inclined surface A of the inclined carrier 1. When placing the battery cells, the battery cells to be stationary are placed sequentially from the bottom end to the upper end of the inclined carrier 1. It is understandable that by adjusting the height of the support rod 31, more horizontal placement surfaces can be formed in the vertical direction, so that the vertical space can be utilized and more battery cells can be placed when the battery cells are stationary.

[0040] like Figure 5 As shown, in one embodiment, the inclined carrier plate 1 includes a carrier plate 30 and support plates 34 arranged in parallel below the carrier plate 30 , and the support plates 34 are fixedly connected by a plurality of reinforcing ribs 35 .

[0041] In the above embodiment, the inclined carrier plate 1 includes a carrier plate 30 and a support plate 34 arranged in parallel below the carrier plate 30, and the support plates 34 are fixedly connected by a plurality of reinforcing ribs 35, wherein the carrier plate 30 is mainly used to carry the battery cells in the static process, and the support plate 34 is used to strengthen the structure of the carrier plate 30, to ensure that the carrier plate 30 is not deformed or damaged in the process of the static battery cells, to avoid the deformation of the carrier plate 30 in the process of the static battery cells, resulting in insufficient fit between the battery cells, the existence of gaps, etc., and further damage to the battery cells, and the support plates 34 are connected by a plurality of reinforcing ribs 35, which can effectively enhance the stability of the entire structure. The arrangement of the support plate 34 and the reinforcing ribs 35 can provide more support and rigidity for the carrier plate 30, avoid deformation or damage when carrying weight, and ensure that the carrier plate 30 can carry more battery cells. Specifically, when the support plate 34 is connected to the reinforcing ribs 35, it can be connected by bolts and threads.

[0042] like Figure 1 , Figure 5 As shown, in one embodiment, the limiting member 2 is a right-angled wedge-shaped or right-angled trapezoidal structure, and a mounting surface is provided on the side opposite to the working surface of the limiting member 2 for fixed connection with the support rod 31 .

[0043] In the above embodiment, the limit member 2 is used to prevent the battery cell from escaping from the inclined surface A of the inclined loading plate 1 when the battery cell is stationary. The shape of the limit member 2 is a right-angled wedge or a right-angled trapezoidal structure, which can ensure that the working surface of the limit member 2 is perpendicular to the inclined surface A of the inclined loading plate 1, and the working surface of the limit member 2 can fit with the battery cell to prevent the battery cell from escaping from the inclined surface A of the inclined loading plate 1. At the same time, it can also form a pressure-maintaining structure with the pressurizing component 4 to maintain the pressure when the battery cell is pressurized; at the same time, the other side opposite to the working surface of the limit member 2 is a mounting surface at an angle to the working surface of the limit member 2, which is used to be fixedly connected to the support frame 3. When connected, due to the action of the mounting surface, it can ensure that the working surface of the limit member 2 and the inclined surface A of the inclined loading plate 1 are perpendicular to each other, thereby avoiding uneven force or deformation or damage to the battery cell during pressurization. Specifically, the limit member 2 and the support frame 3 can be connected by bolts and threads.

[0044] like Figure 5 As shown, in one embodiment, the inclined carrier plate 1 further includes a mounting plate 36 , and the mounting plate 36 is respectively fixedly connected to the carrier plate 30 and the support plate 34 , and is used to be fixedly connected to the support frame 3 .

[0045] In the above embodiment, a mounting plate 36 is further provided at one side of the upper end of the inclined carrier plate 1, and the mounting plate 36 is respectively fixedly connected to the carrier plate 30 and a plurality of parallel support plates 34, so as to enhance the stability of the entire inclined carrier plate 1, and at the same time, the mounting plate 36 is provided with holes for being fixedly connected to the support frame 3. It is understandable that, in the process of the battery cell being stationary, in order to avoid external factors such as collisions, etc., which may cause the inclined carrier plate 1 to fall, or shake, and further cause the stationary battery cell to fall, it is necessary to fix the inclined carrier plate 1, and the fixing method thereof may be to fix the mounting plate 36 to the support frame 3, and specifically, when connected, it may be fixedly connected by bolts and threads.

[0046] like Figure 4 As shown, the support frame 3 includes multiple support rods 31 and multiple layers of inclined brackets 33 inclined relative to the horizontal plane; the multiple support rods 31 are arranged parallel to each other, wherein two support rods 31 are respectively connected to the two ends of the inclined bracket 33 to form a single-sided bracket 5, and adjacent single-sided brackets 5 are combined in pairs to form a placement surface between two inclined brackets 33 at the same position and in the same inclined state of the two single-sided brackets 5, for placing the inclined carrier plate 1 and the limit member 2.

[0047] In the above embodiment, the support frame 3 includes a plurality of support rods 31 and a plurality of inclined brackets 33 inclined relative to the horizontal plane. The plurality of support rods 31 are arranged parallel to each other, wherein two support rods 31 are respectively connected to the two ends of the inclined bracket 33 to form a single-sided bracket 5. For example, see Figure 4, an inclined bracket 33 is arranged between the two support rods 31 of each unilateral bracket 5. It can be understood that multiple inclined brackets 33 can be arranged between the two support rods 31 of a unilateral bracket 5, and the multiple inclined brackets 33 do not contact each other to form a layered structure. The inclination state of the multiple inclined brackets 33 can be inclined in the same direction, or the multiple inclined brackets 33 can be regularly or irregularly inclined in different directions. Adjacent unilateral brackets 5 can be combined in pairs to form a placement surface between two inclined brackets 33 at the same position and in the same inclination state of the two unilateral brackets 5, and the placement surface is used to place the inclined carrier plate 1 and the limit member 2. Since the two adjacent unilateral brackets 5 are not directly connected, a stable support frame 3 structure cannot be formed. Therefore, in actual use, the two adjacent unilateral brackets 5 can be firmly connected by a horizontal bracket 32; for example, Figure 4 As shown, the inclined carrier plate 1 can also be placed on the placement surface formed by the inclined bracket 33, and then the inclined carrier plate 1 is fixed to the inclined bracket 33 by fasteners, such as bolts. At this time, the two single-sided brackets 5 are fixedly connected by the inclined carrier plate 1 to form a stable support frame 3 structure, and then the limiter 2 is installed at the bottom end of the inclined carrier plate 1, and the working surface of the limiter 2 is kept perpendicular to the inclined surface A of the inclined carrier plate 1, and the battery cells to be placed can be placed from the bottom end of the inclined carrier plate 1 along the inclined surface A to the top. It can be understood that a plurality of inclined brackets 33 are arranged between the two support rods 31 of the single-sided bracket 2. When adjacent single-sided brackets 5 are combined in pairs, a multi-layer placement surface is formed between the inclined brackets 33 of the two single-sided brackets 5 at the same position and in the same inclined state, so that a high degree of space utilization is achieved, and more battery cells can be placed when the battery cells are at rest.

[0048] like Figure 6 , Figure 2 As shown, the pressurizing assembly 4 is detachably connected to the support frame 3 , and the working surface of the pressurizing assembly 4 is perpendicular to the inclined surface A of the inclined carrier plate 1 and is arranged on the top of the inclined carrier plate 1 , and is used to squeeze the soft-pack battery cell along the inclined surface A.

[0049] In the above embodiment, the pressurizing component 4 is arranged at the top position of the inclined loading plate 1, and the working surface of the pressurizing component 4 is perpendicular to the inclined surface A of the inclined loading plate 1, which can ensure that when the pressurizing component 4 is pressurized, the battery cell is squeezed along the inclined surface A. At the same time, the pressurizing component 4 and the support frame 3 are detachably connected, which is convenient for replacement and maintenance. Specifically, the connection can be bolted and threaded. It is understandable that when the battery cell is stationary, some self-discharge reactions will occur inside the battery cell, resulting in the loss of charge inside the battery cell. By pressurizing, the rate of this self-discharge can be slowed down and the storage life of the battery cell can be extended.

[0050] like Figure 6 , Figure 7As shown, in one embodiment, the pressurizing assembly 4 is provided with a connecting plate 40 , both ends of the connecting plate 40 are provided with inclined surfaces 402 , and the connecting plate 40 is detachably connected to the supporting frame 3 via the inclined surfaces 402 .

[0051] In the above embodiment, the connecting plate 40 is used for fixed connection between the pressurizing component 4 and the support frame 3. The inclined surface 402 is provided for adjusting the pressurizing direction of the pressurizing part on the pressurizing component 4. Specifically, it can be provided according to the degree of inclination of the inclined carrier plate 1 and the horizontal plane to ensure that the working surface of the pressurizing component 4 is perpendicular to the inclined surface A of the carrier plate 30, so as to avoid uneven force or deformation and damage of the battery cells during the pressurization process. Bolts are used when the inclined surface 402 is connected to the support frame 3.

[0052] like Figure 6 , Figure 7 As shown, in one embodiment, the pressure component 4 is provided with a pressure plate 41 and a sliding rod 43, and a plurality of fastening holes 410 are provided on one side of the pressure plate 41, and the fastening holes 410 are fixedly connected to the sliding rod 43 on the other side by bolts, wherein the sliding rod 43 passes through the connecting plate 40 and is slidably arranged relative to the connecting plate 40.

[0053] Specifically, a plurality of fastening holes 410 are provided at the center of the plate surface of the pressure plate 41 and on both sides of the center of the plate surface. The fastening holes 410 on both sides of the center of the plate surface of the pressure plate 41 are fixedly connected to the sliding rod 43 on the other side by bolts, wherein the sliding rod 43 passes through the connecting plate 40 and is slidably arranged relative to the connecting plate 40.

[0054] In the above embodiment, the pressurizing assembly 4 is provided with a pressurizing plate 41 and a slide bar 43. A plurality of fastening holes 410 are provided at the center of the plate surface of the pressurizing plate 41 and on both sides of the center of the plate surface. The fastening holes 410 located on both sides of the center of the plate surface of the pressurizing plate 41 are mainly used for fixed connection with the slide bar 43 on the side opposite to the working surface of the pressurizing plate 41. Specifically, when connected, the bolts can be passed through the fastening holes 410 and fixedly connected with the internal threaded holes in the slide bar 43. It can be understood that after the pressurizing plate 41 is connected to the slide bar 43, the slide bar 43 passes through the connecting plate 40. When the pressurizing plate 41 squeezes the battery cell, the connecting plate 40 is fixed, and the slide bar 43 is slidably arranged relative to the connecting plate 40. During the process of squeezing the battery cell, the pressurizing plate 41 slides relative to the connecting plate 40 to squeeze the battery cell.

[0055] like Figure 6 , Figure 7 As shown, in one embodiment, the pressurizing assembly 4 is provided with a pressure sensor 42, which is arranged between the pressurizing plate 41 and the connecting plate 40, and is fixed to the pressurizing plate by bolts passing through a fastening hole 410 located at the center of the plate surface of the pressurizing plate 41.

[0056] In the above embodiment, the pressure plate 41 is fixedly connected to the pressure sensor 42 by bolts passing through the fastening holes 410. Since the fastening holes 410 are located at the center of the pressure plate 41, the pressure plate 41 can be subjected to a relatively uniform extrusion force. This helps to ensure that the applied extrusion force can be evenly distributed on the entire surface of the battery cell, achieving a balanced pressurization effect. At the same time, the fastening hole 410 in the center of the pressure plate 41 is connected to the pressure sensor 42 by bolts, which can ensure that the center of gravity of the pressure plate 41 coincides with the center of gravity of the pressure sensor 42, thereby ensuring the overall structural stability and safety of the pressure assembly 4. Specifically, the working surface of the pressure plate 41 abuts against the battery cell during pressurization. It can be understood that the battery cell can withstand limited pressure during the production process. In order to accurately control the pressure and avoid excessive pressure during the process of the pressure plate 41 squeezing the battery cell, it is necessary to use a pressure sensor 42 to control the pressurization pressure.

[0057] like Figure 6 , Figure 7 As shown, in one embodiment, the pressure assembly 4 is provided with a pressure rod 44, and a screw hole part for threaded connection with the pressure rod 44 is provided at the center of the plate surface of the connecting plate 40, and a plurality of bearings 400 for sliding connection with the sliding rod 43 are provided on both sides of the center of the plate surface of the connecting plate 40, and the connecting plate 40 and the pressure plate 41 are slidably connected through the sliding rod 43, and the pressure rod 44 abuts against the pressure sensor 42.

[0058] In the above embodiment, the pressure rod 44 is slidably connected with the connecting plate 40 through the slide bar 43. Since the connecting plate 40 is fixedly connected with the support frame 3 through the inclined surface 402, the pressure plate 41 can slide relative to the connecting plate 40 through the slide bar 43. At the same time, the pressure rod 44 is connected through the threaded member 401 at the center of the plate surface of the connecting plate 40. After the connection, the pressure rod 44 can be moved to abut against the pressure sensor 42. It can be understood that the pressure rod 44 can be a threaded rod. When connected with the threaded member 401, the function of squeezing the pressure sensor 42 can be achieved by rotating the threaded rod. Since the working surface of the pressure plate 41 is in contact with the cell surface on the inclined carrier 1, the side opposite to the working surface of the pressure plate 41 is fixedly connected with the pressure sensor 42. Under the action of the slide bar 43, the function of squeezing the cell can be achieved by twisting the threaded rod. In addition, when the threaded connection is made, the state of the threaded rod and the threaded member 401 can remain unchanged for a certain period of time without rotation, which has the effect of maintaining pressure.

[0059] In summary, the utility model provides a stationary device for soft-pack battery cells, including a support frame 3; an inclined loading plate 1, arranged on the support frame 3 and / or below the support frame 3, for stationary soft-pack battery cells, wherein the surface for supporting the battery cells is an inclined surface A inclined relative to the horizontal plane; and a limit member 2, arranged at the bottom end of the inclined loading plate 1, and the working surface of the limit member 2 is perpendicular to the inclined surface A, for limiting the movement of the soft-pack battery cells; a pressurizing component 4, the working surface of the pressurizing component 4 is perpendicular to the inclined surface A of the inclined loading plate and is arranged at the top of the inclined loading plate 1, for extruding the soft-pack battery cells along the inclined surface A. The utility model installs an inclined carrier plate 1 on a support frame 3, and the surface of the inclined carrier plate 1 for carrying the battery cell is an inclined surface A inclined relative to the horizontal plane, so that the battery cell can be placed. At this time, since the inclined carrier plate 1 is provided with an inclined surface A at an inclined angle to the horizontal plane on the horizontal plane, a stable triangular structure is formed with the horizontal plane, wherein the inclined surface A is the longest side of the triangular structure. The inclined carrier plate 1 is installed on the support frame 3, and then the limiting member 2 is installed at the bottom end of the inclined carrier plate 1, and the working surface of the limiting member 2 is perpendicular to the inclined surface A, so that the battery cell can be placed vertically, so that the working surface of the limiting member 2 fits the battery cell and plays a role. In order to limit the movement of the battery cells, the battery cells can be placed on the inclined surface A of the inclined carrier plate 1, and more battery cells can be placed than on the bottom plane. At the same time, a pressure component is provided on the upper end of the inclined plate to squeeze the battery cells along the inclined surface, thereby ensuring that the battery cells maintain good physical stability during static state and preventing the battery cells from shifting when static. The inclined plate component and the pressure component are both detachably connected to the support frame, which enables more flexible assembly, convenient maintenance and easier replacement of wearing parts, and the support frames can be combined in various forms, which is conducive to scale expansion in the large-scale production of battery cells and has lower overall cost.
