Description

Technical Field

[0001] This application relates to the technical field of batteries, and in particular to a battery baking tooling and a battery baking device. Background Art

[0002] New energy batteries are increasingly widely used in life and industries. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also increasingly used in the energy storage field and so on.

[0003] In the process of manufacturing new energy batteries, it is necessary to perform processes such as formation and grading on the new energy batteries, and these processes require heating and cooling of the new energy batteries. In related technologies, during the heating or cooling process of new energy batteries, the new energy batteries are fixed in a heating device, and a heat conduction medium is introduced into the heating device, or an electric heating wire is arranged in the heating device, etc., to heat up the heating device, so as to heat the new energy batteries. This way of heating the new energy batteries not only easily causes the leaked heat conduction medium to spill on the new energy batteries, but also the heating device cannot contact all surfaces of the new energy batteries, so it is easy to heat the new energy batteries unevenly, thus affecting the heating efficiency of the new energy batteries. Utility Model Content

[0004] This application provides a battery baking tooling and a battery baking device, which can improve the baking efficiency of batteries.

[0005] In the first aspect of this application, a battery baking tooling is provided. The battery baking tooling includes: a bottom bracket and a limiting component; wherein, a guiding member is provided on the bottom bracket; the limiting component includes a plurality of pressing plates arranged side by side, and the plurality of pressing plates are arranged on the guiding member along the extending direction of the guiding member, and a clamping space for clamping the battery is formed between two adjacent pressing plates; a heat exchange channel is provided on the pressing plate, and the heat exchange channel penetrates through the pressing plate in the vertical direction for circulating heat exchange air flow.

[0006] For the battery baking tooling provided by this application, due to the provision of a bottom bracket and a guiding member provided on the bottom bracket, the limiting component composed of a plurality of pressing plates can be arranged on the bottom bracket through the guiding member. And a clamping space is formed between two adjacent pressing plates, and the battery can be placed into the clamping space, so that the battery can be clamped and fixed between two adjacent pressing plates. At the same time, a heat exchange channel is provided on the pressing plate. By blowing hot air flow onto the bottom bracket, the hot air flow can directly blow onto the surface of the battery that does not abut against the pressing plate, so as to heat a part of the surface of the battery; the contact area between the hot air flow and the pressing plate can also be increased through the heat exchange channel, so as to quickly heat the pressing plate, and thus the surface of the battery that abuts against the pressing plate can be heated through the pressing plate, so that all surfaces of the battery can be heated, and further the baking efficiency of the battery can be improved.

[0007] In a possible implementation of the present application, the pressing plate includes a clamping member and a sliding member that are detachably connected; a sliding groove matching the guiding member is provided on the sliding member, and the sliding member is slidably connected to the guiding member through the sliding groove; the heat exchange channel is provided on the clamping member, and the clamping member is used to clamp the battery.

[0008] In the technical solution of the present application, since the pressing plate is set to include a clamping member and a sliding member that are detachably connected, and a sliding groove is provided on the sliding member, clamping members matching each type of battery can be set according to different batteries. Thus, according to the size, structural shape, etc. of the battery that needs to be heated or cooled, a suitable clamping member can be selected, and then the clamping member can be connected to the sliding member, which can achieve rapid clamping member type change and is beneficial to improving the device flexibility of the pressing plate. At the same time, by arranging the heat exchange channel on the clamping member, the clamping member can be quickly heated or cooled, and thus the battery clamped by the clamping member can be heated or cooled.

[0009] In a possible implementation of the present application, there are at least two heat exchange channels on the clamping member, and the extending direction of the guiding member is perpendicular to the vertical direction.

[0010] In the technical solution of the present application, since there are at least two heat exchange channels on the clamping member, it can not only provide more flow space for the hot air flow or cold air flow, but also increase the surface area of the clamping member and reduce the thickness of each part of the clamping member, so as to effectively increase the contact area between the hot air flow or cold air flow and the clamping member, thereby improving the heat exchange efficiency between the clamping member and the hot air flow or cold air flow. At the same time, setting the extending direction of the guiding member to be perpendicular to the vertical direction can reduce the influence of the bottom bracket and other structural members in the pressing plate on the air flow, enable the air flow to directly blow onto the surface of the battery that is not in contact with the clamping member, and enable more air flow to directly blow onto the clamping member, thereby increasing the heating or cooling speed of the clamping member.

[0011] In a possible implementation of the present application, a heat exchange structure is provided on the wall surface of the heat exchange channel.

[0012] In the technical solution of the present application, since a heat exchange structure is provided on the wall surface of the heat exchange channel, the surface area of the heat exchange channel can be increased, thereby increasing the contact area between the air flow and the clamping member, which is beneficial to improving the heat exchange efficiency between the air flow and the clamping member.

[0013] In a possible implementation of the present application, along the extending direction of the guiding member, limiting protrusions are provided on the clamping surface of the clamping member, and the shape of the limiting protrusions matches that of the battery and is used to limit the position of the battery on the clamping member.

[0014] In the technical solution of the present application, since a limiting protrusion is provided on the clamping member, during the process of clamping the battery on the pressing plate, the battery can not only be supported by the limiting protrusion, but also the clamping position of the battery on the pressing plate can be limited by the limiting protrusion.

[0015] In a possible implementation manner of the present application, along the extending direction of the guiding member, a heat conducting member is provided on the clamping surface of the clamping member, and the battery abuts against the clamping member through the heat conducting member.

[0016] In the technical solution of the present application, since a heat conducting member is provided on the clamping surface of the clamping member, the contact area between the battery and the clamping surface can be increased through the heat conducting member. At the same time, the heat conducting member can be made of a material with a relatively high heat conduction coefficient, so as to improve the heat exchange efficiency between the clamping member and the battery.

[0017] In a possible implementation manner of the present application, along the vertical direction, one side of the clamping member has a positioning block, and the positioning block abuts against the bottom bracket to limit the movement of the clamping member relative to the bottom bracket along the vertical direction.

[0018] In the technical solution of the present application, since a positioning block is provided on the clamping member, the position of the clamping member relative to the bottom bracket along the vertical direction can be limited by the positioning block, so that the limiting protrusions, heat conducting members, etc. on two adjacent clamping members can correspond to each other respectively, which is beneficial to improving the accuracy and stability of clamping the battery by two adjacent pressing plates, and thus the risk of damaging the battery during the clamping process can be reduced.

[0019] In a possible implementation manner of the present application, one of the clamping member and the sliding member is provided with a clamping groove formed along the vertical direction, and the other of the clamping member and the sliding member is provided with a clamping protrusion matching the clamping groove, and the clamping member and the sliding member are detachably connected through the clamping groove and the clamping protrusion.

[0020] In the technical solution of the present application, since a clamping protrusion and a clamping groove are respectively provided on the clamping member and the sliding member, the clamping member can be slidably clamped on the sliding member along the vertical direction, so as to facilitate the quick installation of the clamping member on the sliding member or the disassembly and separation of the clamping member and the sliding member.

[0021] In a possible implementation manner of the present application, one of the clamping member and the sliding member is provided with a positioning protrusion, and the other of the clamping member and the sliding member is provided with a positioning groove matching the positioning protrusion, and the positioning protrusion is connected to the positioning groove to limit the movement of the clamping member relative to the sliding member along the vertical direction.

[0022] In the technical solution of the present application, since a positioning protrusion and a positioning groove are respectively provided on the clamping member and the sliding member, during the process of slidably connecting the clamping member and the sliding member, it is convenient to limit the installation position of the clamping member relative to the sliding member along the vertical direction through the positioning protrusion and the positioning groove.

[0023] In a possible implementation manner of the present application, the guiding member includes at least two guiding rods that satisfy a parallel relationship, and the sliding groove is located on a side of the sliding member away from the clamping member.

[0024] In the technical solution of the present application, since the guiding member on the bottom bracket is set in the structural form of a guiding rod, and the sliding groove on the sliding member in the pressing plate is set in the structural form of a groove, the pressing plate can slide along the guiding rod through the sliding groove, so as to facilitate adjusting the position of each pressing plate on the bottom bracket according to the thickness of the battery, and adjusting the width of the clamping space along the extending direction of the guiding member.

[0025] In a possible implementation manner of the present application, along the extending direction of the guiding member, a connecting protrusion is provided on one side of the sliding member, and a connecting groove matching the connecting protrusion is provided on the other side of the sliding member; two adjacent pressing plates are detachably connected through the connecting protrusion and the connecting groove.

[0026] In the technical solution of the present application, since along the extending direction of the guiding member, a matching connecting protrusion and connecting groove are respectively provided on both sides of the sliding member, two adjacent sliding members can be detachably connected through the connecting protrusion and the connecting groove, so as to facilitate detachably connecting two adjacent pressing plates, and a clamping space with a determined width can also be formed between two adjacent pressing plates through the connecting protrusion and the connecting groove.

[0027] In a possible implementation manner of the present application, the battery baking tooling further includes a locking member, and along the extending direction of the guiding member, the locking member is provided at one end of the bottom bracket for limiting the movement of the pressing plate relative to the bottom bracket.

[0028] In the technical solution of the present application, since a locking member is provided on the bottom bracket, the movement of the pressing plate relative to the bottom bracket can be restricted through the locking member. Thus, when an acting force along the extending direction of the guiding member is applied to the pressing plate to apply a pressing force to the battery, the position of the pressing plate relative to the bottom bracket can be locked and restricted through the locking member, so as to facilitate enabling the battery to continuously receive the required pressing force, thereby reducing the risk of deformation of the battery due to thermal expansion.

[0047] At present, new energy batteries are increasingly used in life and industry. New energy batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0048] In the process of producing new energy batteries, some production processes require that the new energy batteries be placed in a higher temperature environment, while some production processes require that the new energy batteries be placed in a lower temperature environment. For example, in the process of forming lithium batteries, it is usually necessary to keep the battery cells in an ambient temperature of about 50 degrees; in the case of high temperature tests on battery cells, it is usually necessary to keep the battery cells in an ambient temperature of about 55 degrees; in the case of low temperature tests on battery cells, it is usually necessary to keep the battery cells in an ambient temperature of about -20 degrees.

[0049] In the process of heating or cooling the battery cell, a tooling that matches the battery cell is usually required to clamp the battery cell through the tooling and heat or cool it. In the related art, in the process of heating or cooling the battery cell through the tooling, the battery cell is clamped in the tooling, and then the tooling is heated by electric heating wire or heat-conducting liquid to transfer the heat of the tooling to the battery cell through the surface where the tooling abuts the battery cell. However, some surfaces on the battery cell are provided with protruding parts, such as poles protruding from the top cover surface of the battery cell, and the contact area between the battery cell and the tooling cannot be increased by clamping the top cover, which will affect the efficiency of heating the battery cell.

[0050] The present application embodiment provides a battery baking tool, referring toFigure 1 , Figure 2 and Figure 3 , Figure 1 shows an exploded structural schematic diagram of the battery baking tooling provided by the present application, Figure 2 shows an assembled structural schematic diagram of the battery baking tooling provided by the present application, Figure 3 shows a structural schematic diagram of the limiting component in the battery baking tooling provided by the present application. For the convenience of description and illustration, the following takes a square shell battery as an example to describe the battery baking tooling provided by the embodiments of the present application, but it does not limit that the battery baking tooling can only be used for heating and baking the square shell battery. The battery baking tooling provided by the embodiments of the present application can be used for performing required heating, heat preservation or cooling treatment on any applicable battery or parts and components in the battery.

[0051] The battery baking tooling provided by the embodiments of the present application includes: a bottom bracket 1 and a limiting component; wherein, the bottom bracket 1 is provided with a guiding member 11; the limiting component includes a plurality of pressing plates 2 arranged side by side, and the plurality of pressing plates 2 are arranged on the guiding member 12 along the extending direction C of the guiding member 11, and a clamping space for clamping the battery 3 is formed between two adjacent pressing plates 2; a heat exchange channel 211 is arranged on the pressing plate 2, and the heat exchange channel 211 penetrates through the pressing plate 2 in the vertical direction F for circulating heat exchange air flow.

[0052] In the embodiments of the present application, the bottom bracket 1 is used to provide installation and support for the limiting component, and the limiting component can be installed on the bottom bracket 1. And the limiting component can be installed on the bottom bracket 1 in a movable connection manner so as to be able to adjust the position of the limiting component on the bottom bracket 1 according to the size of the battery 3, etc., so as to facilitate clamping the battery 3 through the limiting component.

[0053] Exemplarily, as Figure 1 shown, the bottom bracket 1 can be set to a structural form including an end plate 13 and a guiding member 12. Among them, the guiding member 12 can be in the structural form of a planar frame, that is, the guiding member 12 is formed by cross-connecting a plurality of cross beams and longitudinal beams; an end plate 13 can be fixed at each end of the guiding member 12 to form the main structure of the bottom bracket 1. The guiding member 11 can also be arranged on the bottom bracket 1, such as arranging the guiding member 11 between the two end plates 13.

[0054] In the embodiments of the present application, as Figure 1 and Figure 2 shown, the limiting component can be set to a structural form including a plurality of pressing plates 2. A plurality of pressing plates 2 can be arranged side by side on the bottom bracket 1 along the extending direction C of the guiding member 11, and the plurality of sequentially arranged pressing plates 2 form the limiting component.

[0055] Exemplarily, a certain gap can be reserved between two adjacent pressing plates 2, so that a clamping space can be formed between the two adjacent pressing plates 2, and the battery 3 can be accommodated in the clamping space, thereby fixing the battery 3 on the limiting component.

[0056] Another example is as Figure 3 shown. A heat exchange channel 211 can be provided on each pressing plate 2 in the limiting component to form a gas flow path on the pressing plate 2 through the heat exchange channel 211, so that the surface area of the pressing plate 2 can be increased, thereby increasing the contact area between the gas and the pressing plate 2. For example, the heat exchange channel 211 can be set in the structural form of a through hole, such as a through hole in the shape of a rectangle, a circle, a triangle, etc.

[0057] It should be noted that the vertical direction F can be the flow direction of the gas when it flows through the battery baking tooling. The clamping direction of the pressing plate 2 clamping the battery 3 can be the direction in which the pressing plate 2 applies a force to the battery 3, that is, the pressing plate 2 can move relative to the bottom bracket 1 along the extension direction C of the guiding member 11 to adjust the distance between two adjacent pressing plates 2, so as to determine the magnitude of the force applied to the battery 3. The extension direction C of the guiding member 11 can have an included angle with the extension direction (vertical direction F) of the heat exchange channel 211. For example, the extension direction C of the guiding member 11 can be perpendicular or nearly perpendicular to the extension direction of the heat exchange channel 211, or the included angle between the extension direction C of the guiding member 11 and the extension direction of the heat exchange channel 211 can be set to other included angles greater than 0 degrees and less than 90 degrees.

[0058] In this way, during the process of heating, insulating or cooling the battery 3 by using the battery baking tooling, hot air or cold air can be blown to the battery baking tooling clamping the battery 3, so that the hot air or cold air can directly blow to the surface of the battery 3 that is not in contact with the pressing plate 2, and heat or cool the surface of the battery 3 that is not in contact with the pressing plate 2. At the same time, the hot air or cold air can blow to the pressing plate 2 and flow through the heat exchange channel 211 on the pressing plate 2, so as to heat or cool the pressing plate 2, thereby heating or cooling the surface of the battery 3 in contact with the pressing plate 2 through the pressing plate 2, and thus all surfaces of the battery 3 can be heated or cooled.

[0059] The battery baking tooling provided by the embodiments of the present application is provided with a bottom bracket 1, and a guiding member 11 is arranged on the bottom bracket 1. A limiting component composed of a plurality of pressing plates 2 can be arranged on the bottom bracket 1 through the guiding member 11. And a clamping space is formed between two adjacent pressing plates 2, and a battery can be placed into the clamping space, so that the battery can be clamped and fixed between two adjacent pressing plates 2. At the same time, a heat exchange channel 211 is arranged on the pressing plate 2. By blowing hot air flow onto the bottom bracket 1, the hot air flow can directly blow onto the surface of the battery that does not abut against the pressing plate 2, so that a part of the surface of the battery 3 can be heated; the contact area between the hot air flow and the pressing plate 2 can also be increased through the heat exchange channel 211, so that the pressing plate 2 can be quickly heated, and thus the surface of the battery that abuts against the pressing plate 2 can be heated through the pressing plate 2, so that all surfaces of the battery can be heated, and further the baking efficiency of the battery can be improved.

[0060] In addition to improving the baking efficiency of the battery through the above structure of the battery baking tooling, the structural components in the battery baking tooling can also be flexibly set, so that the battery baking tooling can adapt to wider production requirements and improve the baking efficiency of the battery. The following will be described in conjunction with embodiments and drawings.

[0061] In some possible embodiments of the present application, as Figure 3 shown, the pressing plate 2 includes a detachable clamping member 21 and a sliding member 22. A sliding groove 221 matching the guiding member 11 is arranged on the sliding member 22, and the heat exchange channel 211 is arranged on the clamping member 21, and the clamping member 21 is used for clamping the battery.

[0062] In the embodiments of the present application, as Figure 3 shown, the pressing plate 2 can be configured in a structural form including a clamping member 21 and a sliding member 22, and the clamping member 21 and the sliding member 22 are detachably connected.

[0063] Exemplarily, the clamping member 21 and the sliding member 22 can be connected in a snap-fit manner. For example, the clamping member 21 is set as a cubic plate-shaped structure, and a sliding member 22 is detachably installed at each of the two ends of the plate-shaped clamping member 21 parallel to the vertical direction F. A sliding groove 221 matching the guiding member 11 can be arranged on the sliding member 22, so that the pressing plate 2 can move along the guiding member 11 of the bottom bracket 1 through the sliding member 22. For example, the sliding groove 221 can be set as a U-shaped groove. In this way, the sliding member 22 can be first installed on the guiding member 11, and then the clamping member 21 can be installed on the two opposite sliding members 22.

[0064] In another example, a structure matching the battery 3 can be provided on the clamping member 21, so as to clamp and fix the battery 3 on the battery baking tooling through the clamping member 21. The heat exchange channel 211 can be arranged on the clamping member 21, so that the clamping member 21 can be quickly heated or cooled, and thus the battery 3 can be heated or cooled. Both the clamping member 21 and the sliding member 22 can be made of materials such as aluminum, copper, and alloys.

[0065] In the above embodiment, since the pressing plate 2 is set to include a clamping member 21 and a sliding member 22 that are detachably connected, and a sliding groove 221 is arranged on the sliding member 22, clamping members 21 matching each type of battery 3 can be set according to different batteries 3. Thus, according to the size and structural shape of the battery 3 that needs to be heated or cooled, a suitable clamping member 21 can be selected, and then the clamping member 21 is connected to the sliding member 22, which can realize the quick type change of the clamping member 21 and is beneficial to improving the device flexibility of the pressing plate 2. At the same time, arranging the heat exchange channel 211 on the clamping member 21 can quickly heat or cool the clamping member 21, so that the clamped battery 3 can be heated or cooled through the clamping member 21.

[0066] In some possible embodiments of the present application, there are at least two heat exchange channels 211 on the clamping member 21, and the extending direction C of the guiding member 11 and the vertical direction F satisfy a perpendicular relationship.

[0067] In the embodiments of the present application, as Figure 3 shown, a plurality of heat exchange channels 211 can be arranged on the clamping member 21, and the heat exchange channels 211 can be arranged in the structural form of through holes penetrating the clamping member 21.

[0068] Exemplarily, when the clamping member 21 is set to be cubic in shape, the size of the clamping member 21 can be set according to the size of the battery 3. For example, the size of the clamping member 21 is set to be able to clamp two batteries 3. For example, in the vertical direction F, the width of the clamping member 21 matches the width of the battery 3, and in the length direction of the clamping member 21, the length of the clamping member 21 is greater than the length of two batteries 3, and two batteries 3 can be clamped side by side between the clamping members 21.

[0069] In another example, the extending direction of the heat exchange channel 211 can be set to be perpendicular or nearly perpendicular to the extending direction C of the guiding member 11. In this way, a plurality of through holes can be arranged on the clamping member 21 in a direction perpendicular to the extending direction C of the guiding member 11. For example, the heat exchange channel 211 is set as a square through hole, and a plurality of adjacent square through holes penetrate the clamping member 21.

[0070] In the above embodiments, since at least two heat exchange channels 211 are provided on the clamping member 21, it is possible not only to provide more flow space for hot air flow or cold air flow, but also to increase the surface area of the clamping member 21 and reduce the thickness of each part of the clamping member 21, so as to effectively increase the contact area between the hot air flow or cold air flow and the clamping member 21, thereby improving the heat exchange efficiency between the clamping member 21 and the hot air flow or cold air flow. At the same time, setting the extension direction C of the guiding member 11 and the vertical direction F to satisfy the perpendicular relationship can reduce the influence of other structural members in the bottom bracket 1 and the pressing plate 2 on the air flow, enable the air flow to directly blow onto the surface of the battery 3 that is not in contact with the clamping member 21, and enable more air flow to directly blow onto the clamping member 21, thereby increasing the heating or cooling speed of the clamping member 21.

[0071] In some possible embodiments of the present application, a heat exchange structure is provided on the wall surface of the heat exchange channel 211.

[0072] In the embodiments of the present application, the extension direction of the heat exchange channel 211 is set to be consistent with the vertical direction F. During the process of the air flow passing through the heat exchange channel 211, the flow direction of the air flow is parallel to the extension direction of the wall surface of the heat exchange channel 211. Although the air flow can quickly pass through the heat exchange channel 211, the contact time between the air flow and the wall surface enclosing the heat exchange channel 211 is reduced.

[0073] Exemplarily, protrusions and grooves can be provided on the wall surface of the heat exchange channel 211 of the clamping member 21, so that the wall surface enclosing the heat exchange channel 211 is an uneven surface, and these protrusions and grooves are used as the heat exchange structure on the heat exchange channel 211. In this way, the heat exchange structure can increase the surface area of the heat exchange channel 211.

[0074] In the above embodiments, since a heat exchange structure is provided on the wall surface of the heat exchange channel 211, the surface area of the heat exchange channel 211 can be increased, thereby increasing the contact area between the air flow and the clamping member 21, which is beneficial to improving the heat exchange efficiency between the air flow and the clamping member 21.

[0075] In some possible embodiments of the present application, refer to Figure 4 , Figure 4 shows an exploded structural schematic diagram of the pressing plate in the battery baking tooling provided by the present application. Along the extension direction C of the guiding member 11, a limiting protrusion 213 is provided on the clamping surface 212 of the clamping member 21, and the shape of the limiting protrusion 213 matches that of the battery 3, and is used to limit the position of the battery on the clamping member 21.

[0076] In the embodiments of the present application, a limiting protrusion 213 matching the battery can be provided on the clamping member 21, so as to facilitate limiting the clamping position of the battery on the clamping member 21 through the limiting protrusion 213.

[0077] Exemplarily, along the extension direction C of the guide member 11, a limit projection 213 may be provided on the clamping surface 212 of the clamping member 21. For example, the limit projection 213 may be arranged in a structure form of a semi-circular rib that is approximately U-shaped, or the limit projection 213 may be arranged as two opposite right-angled ribs that are approximately L-shaped, and the semi-circular rib or the right-angled rib extends from the clamping surface 212 in a direction away from the center of the clamping member 21. And at least two semi-circular limit projections 213 may be provided on one clamping surface 212. In this way, at least two batteries 3 can be supported by the semi-circular rib, and the position of the battery 3 on the clamping member 21 can be restricted.

[0078] In another example, along the extension direction C of the guide member 11, limit projections 213 may be provided on both of the two opposite clamping surfaces 212 of the clamping member 21. As Figure 1 and Figure 2 shown, a plurality of pressing plates 2 may be installed on the bottom bracket 1. In this way, at least two batteries 3 can be clamped and fixed between two adjacent clamping members 21, and the same battery 3 can be supported and restricted by two opposite limit projections 213 on two adjacent clamping members 21.

[0079] In the above embodiments, since the limit projection 213 is provided on the clamping member 21, during the process of clamping the battery on the pressing plate 2, not only can the battery be supported by the limit projection 213, but also the clamping position of the battery on the pressing plate 2 can be defined by the limit projection 213.

[0080] In some possible embodiments of the present application, along the extension direction C of the guide member 11, a heat conducting member 23 is provided on the clamping surface 212 of the clamping member 21, and the battery abuts against the clamping surface 212 through the heat conducting member 23.

[0081] In the embodiments of the present application, as Figure 3 and Figure 4 shown, a heat conducting member 23 may be provided on the clamping member 21 to increase the contact area between the battery 3 and the clamping surface 212 of the clamping member 21 through the heat conducting member 23.

[0082] Exemplarily, a heat conducting member 23 may be provided in each limit projection 213 on each clamping surface 212. For example, two heat conducting members 23 are provided on each clamping surface 212. The heat conducting member 23 may be selected from materials with a higher heat conduction coefficient than that of the clamping member 21. For example, the heat conducting member 23 may be selected from materials such as heat conducting silica gel, heat conducting silicone grease, heat conducting gel, and heat conducting plastic that have a certain elasticity.

[0083] In another example, as Figure 4As shown, heat conduction holes 217 can be provided on the clamping surface 212, and the heat conduction holes 217 communicate with the heat exchange channel 211. Correspondingly, heat conduction posts 231 matching the heat conduction holes 217 can be provided on the heat conduction member 23. In this way, not only can the heat conduction member 23 and the clamping member 21 be fixedly connected through the heat conduction posts 231 and the heat conduction holes 217, but also the contact area between the heat conduction member 23 and the air flow can be increased to improve the heating or cooling efficiency of the heat conduction member 23.

[0084] In the above embodiment, since the heat conduction member 23 is provided on the clamping surface 212 of the clamping member 21, the contact area between the battery 3 and the clamping surface 212 can be increased through the heat conduction member 23. At the same time, the heat conduction member 23 can be made of a material with a relatively high thermal conductivity, so as to improve the heat exchange efficiency between the clamping member 21 and the battery 3.

[0085] In some possible embodiments of the present application, on the vertical direction F, one side of the clamping member 21 has a positioning block 214, and the positioning block 214 abuts against the bottom bracket 1 to limit the movement of the clamping member 21 relative to the bottom bracket 1 in the vertical direction F.

[0086] In the embodiments of the present application, as Figure 3 and Figure 4 shown, on the vertical direction F, the position of the sliding member 22 relative to the bottom bracket 1 can be restricted by the guiding member 11 and the sliding groove 221. The clamping member 21 and the bottom bracket 1 are connected through the sliding member 22, and on the vertical direction F, the clamping member 21 may move relative to the bottom bracket 1. Then, a positioning block 214 adapted to the bottom bracket 1 can be provided on the clamping member 21 to limit the movement of the clamping member 21 relative to the bottom bracket 1 in the vertical direction F through the positioning block 214.

[0087] Exemplarily, as Figure 1 shown, the guiding member 12 in the bottom bracket 1 can be used as a structural member to limit the movement of the clamping member 21 relative to the bottom bracket 1 in the vertical direction F. Correspondingly, as Figure 3 shown, a positioning block 214 can be provided on the side of the clamping member 21 facing the guiding member 12. For example, the positioning block 214 can be set as a convex block extending from the clamping member 21 in the direction facing the guiding member 12. Two convex blocks serving as the positioning block 214 can be provided on each clamping member 21, and through holes or grooves can be provided on the convex block to increase the surface area of the positioning block 214.

[0088] In the above embodiments, since the positioning block 214 is provided on the clamping member 21, the position of the clamping member 21 relative to the bottom bracket 1 in the vertical direction F can be restricted by the positioning block 214, so that the limiting protrusions 213, heat conducting members 23, etc. on two adjacent clamping members 21 can correspond to each other respectively, which is beneficial to improving the accuracy and stability of clamping the battery 3 by two adjacent pressing plates 2, and thus the risk of damaging the battery 3 during the clamping process of the battery 3 can be reduced.

[0089] In some possible embodiments of the present application, a clamping groove 222 formed along the vertical direction F is provided on one of the clamping member 21 and the sliding member 22, and a clamping protrusion 215 matching the clamping groove 222 is provided on the other of the clamping member 21 and the sliding member 22. The clamping member 21 and the sliding member 22 are detachably connected through the clamping groove 222 and the clamping protrusion 215.

[0090] In the embodiments of the present application, in order to facilitate the detachable connection between the clamping member 21 and the sliding member 22, the clamping member 21 and the sliding member 22 can be detachably connected in a sliding clamping manner.

[0091] Exemplarily, as Figure 3 shown, in the vertical direction F, a clamping groove 222 can be provided on the sliding member 22. Correspondingly, a clamping protrusion 215 extending along the vertical direction F can be provided at each end of the clamping member 21, and the clamping protrusion 215 matches the clamping groove 222 on the sliding member 22. Alternatively, a clamping protrusion can also be provided on the sliding member 22, and a clamping groove matching the clamping protrusion can be provided on the clamping member 21. Then, the clamping protrusion 215 can be slidably connected with the clamping groove 222 along the vertical direction F to insert the clamping member 21 into two sliding members 22 along the vertical direction F.

[0092] In the above embodiments, since the clamping protrusion 215 and the clamping groove 222 are respectively provided on the clamping member 21 and the sliding member 22, the clamping member 21 can be slidably clamped on the sliding member 22 along the vertical direction F, so as to facilitate the rapid installation of the clamping member 21 on the sliding member 22 or the disassembly and separation of the clamping member 21 from the sliding member 22.

[0093] In some possible embodiments of the present application, referring to Figure 5 , Figure 5 shows the structural schematic diagram of the pressing plate in the battery baking tooling provided by the present application Figure 2 . A positioning protrusion 216 is provided on one of the clamping member 21 and the sliding member 22, and a positioning groove matching the positioning protrusion 216 is provided on the other of the clamping member 21 and the sliding member 22. The positioning protrusion 216 is connected with the positioning groove to restrict the movement of the clamping member 21 relative to the sliding member 22 in the vertical direction F.

[0094] In the embodiments of the present application, during the process of slidingly clamping the clamping member 21 and the sliding member 22, in order to limit the movement position of the clamping member 21 relative to the sliding member 22, a matching positioning structure can be provided between the clamping member 21 and the sliding member 22.

[0095] Exemplarily, as Figure 4 and Figure 5 shown, a positioning protrusion 216 can be provided on the clamping member 21, and a positioning groove matching the positioning protrusion 216 can be provided on the sliding member 22. Alternatively, a positioning groove can be provided on the clamping member 21, and a positioning protrusion matching the positioning groove can be provided on the sliding member 22. For example, the positioning protrusion 216 can be set in the structural form of a buckle, and the positioning groove can be set as a card slot matching the buckle. For example, a buckle is provided on the clamping protrusion 215 of the clamping member 21, and a card slot is provided in the card slot 222 of the sliding member 22, and the buckle can be set as an elastic buckle. In this way, during the process of slidingly connecting or disassembling the clamping member 21 and the sliding member 22, it is convenient for the buckle to be inserted into the card slot and for the buckle to be separated from the card slot.

[0096] In the above embodiments, since the positioning protrusion 216 and the positioning groove are respectively provided on the clamping member 21 and the sliding member 22, during the process of slidingly connecting the clamping member 21 and the sliding member 22, it is convenient to limit the installation position of the clamping member 21 relative to the sliding member 22 along the vertical direction F through the positioning protrusion 216 and the positioning groove.

[0097] In some possible embodiments of the present application, the guiding member 11 includes at least two guiding rods that satisfy a parallel relationship, and the sliding groove 221 is located on the side of the sliding member 22 away from the clamping member 21.

[0098] In the embodiments of the present application, as Figure 1 shown, the guiding member 11 in the bottom bracket 1 can be set as a rod-shaped guiding rod. Correspondingly, as Figure 3 shown, the sliding groove 221 on the sliding member 22 can be set as a groove matching the guiding rod.

[0099] Exemplarily, the guiding rod can be set as a cylindrical long rod, and the sliding groove can be set as a U-shaped groove matching the cylindrical long rod, that is, the bottom of the sliding groove 221 can be in close contact with the circumferential side surface of the cylindrical long rod. For example, eight guiding rods are provided in the bottom bracket 1, and two sliding grooves 221 are provided on each sliding member 22. Among them, every two guiding rods correspond to one sliding member 22, and these two guiding rods are parallel or nearly parallel to each other. That is, every four guiding rods are a group, and then two columns of limiting components can be installed on the bottom bracket 1 through two groups of guiding rods. Each column of limiting components includes at least two pressing plates 2.

[0100] In the above embodiments, since the guiding member 11 on the bottom bracket 1 is set in the structural form of a guiding rod, and the sliding groove 221 on the sliding member 22 in the pressing plate 2 is set in the structural form of a groove, the pressing plate 2 can slide along the guiding rod through the sliding groove 221, so as to facilitate adjusting the position of each pressing plate 2 on the bottom bracket 1 according to the thickness of the battery 3, and adjusting the width of the clamping space along the extending direction C of the guiding member 11.

[0101] In some possible embodiments of the present application, along the extending direction C of the guiding member 11, a connecting protrusion 223 is provided on one side of the sliding member 22, and a connecting groove 224 matching the connecting protrusion 223 is provided on the other side of the sliding member 22. Two adjacent pressing plates 2 are detachably connected through the connecting protrusion 223 and the connecting groove 224.

[0102] In the embodiments of the present application, as Figure 3 shown, in order to facilitate connecting two adjacent pressing plates 2 and also make there be a clamping space with a determined width between two adjacent pressing plates 2, two matching connecting structures can be provided on the pressing plate 2 to detachably connect two adjacent pressing plates 2 through these two connecting structures.

[0103] Exemplarily, along the extending direction C of the guiding member 11, a connecting protrusion 223 can be provided on one side of the sliding member 22, and a connecting groove 224 can be provided on the other side of the sliding member 22. For example, the connecting protrusion 223 can be a convex block, and the connecting groove 224 can be a groove matching the convex block. If the convex block is set in the structural form with a T-shaped cross-section, correspondingly, the groove is set as a T-shaped groove.

[0104] In the above embodiments, since along the extending direction C of the guiding member 11, a matching connecting protrusion 223 and connecting groove 224 are respectively provided on both sides of the sliding member 22, two adjacent sliding members 22 can be detachably connected through the connecting protrusion 223 and the connecting groove 224, so as to facilitate detachably connecting two adjacent pressing plates 2, and a clamping space with a determined width can also be formed between two adjacent pressing plates 2 through the connecting protrusion 223 and the connecting groove 224.

[0105] In some possible embodiments of the present application, the bottom bracket 1 includes a locking member. Along the extending direction C of the guiding member 11, the locking member is provided at one end of the bottom bracket 1 for limiting the movement of the pressing plate 2 relative to the bottom bracket 1.

[0106] In the embodiments of the present application, a locking member can be provided on an end plate 13 of the bottom bracket 1 to limit the position of the pressing plate 2 on the bottom bracket 1 through the locking member.

[0107] Exemplarily, the locking member can be a bolt, and threaded holes matching the bolt can be provided on the end plate 13. The threaded holes are through holes. For example, a bolt can be provided at a position on the end plate 13 corresponding to each row of pressing plates 2. By screwing the bolt, the bolt can extend into the space between the two end plates 13. In this way, after installing a plurality of pressing plates 2 on the bottom bracket 1, the battery 3 can be clamped between two adjacent pressing plates 2. Then, by applying a clamping force to the pressing plate 2 along the extension direction C of the guide member 11, the battery 3 can be subjected to the required pressing force. Then, the bolt is screwed until it abuts against the clamping member 21 or the sliding member 22, so as to limit the movement of each pressing plate 2 relative to the bottom bracket 1 and provide a continuous pressing force to each battery 3.

[0108] In the above embodiment, since a locking member is provided on the bottom bracket 1, the movement of the pressing plate 2 relative to the bottom bracket 1 can be restricted by the locking member. Thus, when applying a force to the pressing plate 2 along the extension direction C of the guide member 11 to apply a pressing force to the battery 3, the position of the pressing plate 2 relative to the bottom bracket 1 can be locked and restricted by the locking member, so that the battery 3 can continuously receive the required pressing force, thereby reducing the risk of deformation of the battery 3 due to thermal expansion.

[0109] In addition, an embodiment of the present application further provides a battery baking device, which includes: a box body and the battery baking tooling provided in any one of the above embodiments; wherein, the box body encloses to form a baking cavity; and the battery baking tooling is installed in the baking cavity.

[0110] In the embodiment of the present application, the box body can be a closed structural form with heat preservation performance, and a baking cavity can be formed inside the box body.

[0111] Exemplarily, an air conveying device can be provided inside the box body. The air conveying device can be a device capable of generating hot air with a relatively high flow rate (such as the air flow temperature is greater than 60 degrees) or cold air (such as the air flow temperature is lower than minus 20 degrees), or a device capable of generating an air flow with a temperature between 60 degrees and minus 20 degrees and a relatively high flow rate. The embodiment of the present application does not limit the temperature of the air flow generated by the air conveying device.

[0112] Another example, the air conveying device can be set to a structural form including a heating source, a cooling source and a fan. The heating source is used to heat the air flow, the cooling source is used to reduce the temperature of the air flow, and the fan is used to accelerate the air flow. The fan can be located inside the box body.

[0113] In another example, a carrying device can be arranged on the cavity wall of the baking cavity of the box body. The carrying device can be in a structural form with multiple carrying brackets. For example, a plurality of supporting members for carrying the battery baking tooling can be arranged on the inner wall of the box body, and at least two opposite supporting members form a carrying bracket, and each carrying bracket can place and support a bottom bracket 1. And the multiple carrying brackets can be arranged along the flowing direction of the air flow generated by the air conveying device. In this way, when a plurality of battery baking toolings are placed on the carrying brackets, the air flow can flow through the plurality of battery baking toolings in sequence, so as to facilitate heating, heat preservation or cooling of the batteries clamped in each battery baking tooling.

[0114] The battery baking device provided by the embodiment of the present application, because a box body is provided and a baking cavity is enclosed inside the box body, hot air flow can flow in the baking cavity. At the same time, it includes the battery baking tooling provided by the above embodiment, and all surfaces of the battery clamped in the battery baking tooling can be heated by hot air flow, so that the baking efficiency of the battery can be improved.

In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
