Description

Technical Field

[0001] The present application belongs to the technical field of battery production, and in particular, relates to a heating device and a battery processing system. Background Art

[0002] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor in their development.

[0003] During the production and processing of batteries, the batteries need to be heated to improve their reliability. When the battery heating device needs to heat batteries of different specifications, the battery-carrying plate needs to be replaced. The current heating device uses multiple bolts to fix the battery-carrying plate. When changing the type, multiple bolts need to be loosened and retightened after the plate is replaced, which is time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] In view of the above problems, the present application provides a heating device and a battery processing system, which simplify the mold change steps and improve the mold change efficiency.

[0005] In a first aspect, the present application provides a heating device for heating a battery, the heating device comprising:

[0006] Pedestal;

[0007] A carrier, used for carrying the battery, and the carrier is arranged on the base;

[0008] The base is provided with a self-locking structure for detachably locking the bearing member, and the bearing member is provided with an adapting structure adapted to lock with the self-locking structure.

[0009] In the technical solution of this embodiment, the self-locking structure cooperates with the adapter structure of the carrier to fix the carrier on the base. When the heating device needs to be replaced, it is only necessary to open the self-locking mechanism and close the self-locking structure after replacing the carrier. Compared with the method of loosening and tightening multiple nuts, this setting simplifies the replacement steps and improves the replacement efficiency.

[0010] In some embodiments, the self-locking structure includes a driving member disposed on a base and a clamping arm connected to the driving member, and the driving member is used to drive the clamping arm to press against the adapting structure.

[0011] The technical solution of this embodiment provides some specific structures of the self-locking structure, and the driving member drives the clamping arm to press the adapting structure to achieve the effect of locking the bearing member.

[0012] In some embodiments, the adapting structure includes a pressing portion connected to the carrier, and the pressing portion is disposed on a side of the carrier facing the base;

[0013] The clamping arm is used for pressing the pressing part.

[0014] In the technical solution of this embodiment, the pressing portion is arranged on the side of the carrier facing the base, that is, the pressing portion is arranged on the side of the carrier away from the battery cell; because the clamping arm is used to press the pressing portion on the driving member, the driving member and the clamping arm need to be on opposite sides of the pressing portion. Providing the pressing portion on the side of the carrier facing the base can reduce the situation where the clamping arm or the driving member protrudes from the carrier, thereby allowing the battery to be placed on the carrier more stably.

[0015] In some embodiments, the drive member is capable of driving the clamping arm to move between the first position and the second position;

[0016] When the clamping arm is in the first position, the clamping arm is pressed on the pressing portion, and the orthographic projection of the clamping arm on the base at least partially overlaps with the orthographic projection of the pressing portion on the base;

[0017] When the clamp arm is at the second position, the clamp arm is separated from the pressing portion, and the orthographic projection of the clamp arm on the base is offset from the orthographic projection of the pressing portion on the base.

[0018] In the technical solution of this embodiment, the clamping arm has a first position and a second position. The clamping arm can press the pressing part on the driving part in the first position to fix the carrier. The clamping arm can also be separated from the pressing part and staggered with the pressing part in the second position to reduce interference with the disassembly of the carrier, so that the carrier can be removed more conveniently.

[0019] In some embodiments, the self-locking structure includes a driving member disposed on a base and at least two abutting fingers connected to the driving member, and the driving member is used to drive the at least two abutting fingers to move closer to or away from each other so that the abutting fingers abut or detach from the carrier.

[0020] The technical solution of this embodiment provides some other specific structures of the self-locking structure, where a driving member drives at least two abutting fingers to clamp the bearing member, thereby achieving the effect of fixing the bearing member.

[0021] In some embodiments, the adapting structure includes a holding hole, and the holding hole is opened on a side of the carrier facing the base;

[0022] At least a portion of the abutting finger extends into the clamping hole, and the abutting finger is used to abut against the inner wall of the clamping hole.

[0023] In the technical solution of this embodiment, a clamping hole is opened on the carrier so that the holding finger can be pressed against the inner wall of the clamping hole, thereby fixing the carrier; at the same time, this arrangement can reduce the situation where the holding finger protrudes from the carrier, so that the battery can be placed on the carrier more stably.

[0024] In some embodiments, the heating device further comprises a first support member disposed on the carrier, and the first support member is used to be supported on the base.

[0025] In the technical solution of this embodiment, the first support member is supported on the base and connected to the bearing member, so that the bearing member is supported by the first support member, thereby reducing the pressure on the self-locking structure and improving the stability and service life of the self-locking structure.

[0026] In some embodiments, a receiving groove is provided on the first support member;

[0027] The heating device also includes a supporting block arranged on the base, wherein the supporting block is accommodated in the accommodating groove and abuts against the inner wall of the accommodating groove.

[0028] In the technical solution of this embodiment, the pressure on the bearing member is shared by the support block; at the same time, the support block can also limit the horizontal displacement of the bearing member. When the bearing member is subjected to horizontal pressure, the support block can provide support for the bearing member through the first support member, thereby reducing the pressure on the self-locking structure and protecting the self-locking structure.

[0029] In some embodiments, the support block tapers in a direction away from the base.

[0030] In the technical solution of this embodiment, the support block is gradually contracted in a direction away from the base, so that the support block can be more easily clamped in the receiving groove during the installation of the bearing member.

[0031] In some embodiments, a marking structure is provided on the carrier;

[0032] The heating device also includes an identification device arranged on the base, and the identification device is used to identify the identification structure.

[0033] The technical solution of this embodiment provides a structure for identifying a carrier, and identification structures with different structures can be set on different carriers, or the identification structures can be set at different positions of the carrier, so that the identification device can determine the relevant parameters of the corresponding carrier through the structure or position of the identification structure.

[0034] In some embodiments, at least two installation positions are provided on the carrier, and the identification structure can be installed at any installation position. The identification device is also used to obtain position information of the identification structure.

[0035] The technical solution of this embodiment further provides some methods for identification devices to identify different carriers, so that the identification structure can be installed at different positions of the carrier, so that the positions of the identification structures on different carriers are different, and at the same time enable the identification device to obtain the position information of the identification structure, so that the identification device can determine the relevant parameters of the corresponding carrier through the position information.

[0036] In some embodiments, the heating device further comprises a second support member disposed on the carrier, and the second support member is used to be supported on the base.

[0037] In the technical solution of this embodiment, the second support member is supported on the base and connected to the bearing member, so that the bearing member is supported by the second support member, thereby reducing the pressure on the self-locking structure and improving the stability and service life of the self-locking structure.

[0038] In a second aspect, some embodiments of the present application further provide a battery processing system, comprising the heating device provided by some embodiments of the first aspect.

[0039] The above description is only an overview of the technical solution of the present application.

[0067] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0068] During the production and processing of batteries, the side plates and end plates of the batteries are mostly connected by welding, gluing, etc. During the connection process, gaps and other structures may remain, resulting in loose connections between the components. In addition, some structures in the battery have low charging and discharging efficiency at low temperatures, which may lead to low charging and discharging efficiency of the battery.

[0069] In order to make the connections between the various components in the battery tighter and to improve the efficiency of the battery, the battery is currently heated and pressurized after assembly to increase the tightness of the connection between the various components of the battery, reduce the connection gap, and improve the stability of the battery, thereby improving the battery's charging and discharging efficiency, and discharge water vapor, condensation, etc. in the battery to improve the battery's safety performance.

[0070] During the battery production and processing, heating equipment is often used to heat and pressurize the battery. When the current heating equipment needs to process batteries of different specifications, it is necessary to remove the plates used to support the batteries in the heating equipment and replace them with plates of corresponding specifications. However, the current plates are mostly fixed to the heating equipment with a large number of bolts, which means that when replacing the plates, the screws need to be unscrewed one by one and then the plates need to be removed, and the screws need to be tightened one by one after the plates are replaced. This process is cumbersome, time-consuming, labor-intensive, and inefficient.

[0071] Based on the above considerations, in order to improve the efficiency of panel replacement, an embodiment of the present application provides a heating device, a self-locking structure is provided on the base, and the carrier is fixed to the base through the self-locking structure.

[0072] In such a heating device, when the carrier needs to be replaced, it is only necessary to open the self-locking structure and then lock the self-locking structure after replacing the carrier; compared with the method of loosening and tightening multiple nuts, this setting simplifies the changeover steps and improves the changeover efficiency.

[0073] In order to illustrate the technical solution described in this application, the following is a description with reference to specific drawings and embodiments.

[0074] First, refer to Figure 1 , Figure 2 Some embodiments of the present application provide a heating device 100 for heating a battery.

[0075] Figure 2 In the figure, the direction of the X-axis is the length direction of the heating device 100, the direction of the Y-axis is the width direction of the heating device 100, and the direction of the Z-axis is the height direction of the heating device 100.

[0076] The heating device 100 includes a base 10 and a carrier 30; the carrier 30 is used to carry the battery, the carrier 30 is arranged on the base 10, the base 10 is provided with a self-locking structure 20 for detachably locking the carrier 30, and the carrier 30 is provided with an adapting structure adapted to lock with the self-locking structure 20.

[0077] The base 10 refers to a structure in the heating device 100 that is mainly used to provide a fixed foundation for the self-locking structure 20 and other structures. The shape of the base 10 can be a thin plate, such as a square thin plate, a circular thin plate or a thin plate of other shapes. The base 10 can also be a prism, a truncated cone or other shapes; the material of the base 10 can include metal, plastic or other materials.

[0078] The carrier 30 refers to the structure in the heating device 100 that is mainly used to support the battery. The carrier 30 can be a plate-like structure, such as a square plate, a circular plate, or a plate structure of other shapes. The carrier 30 can also be a columnar structure with a certain thickness, such as a cylinder, a prism, or a column structure of other shapes. The carrier 30 can also be a structure of other shapes; the material of the carrier 30 can include metal, plastic, or other materials.

[0079] The self-locking structure 20 refers to a structure in the heating device 100 that is mainly used to fix the carrier 30. The self-locking structure 20 can lock the carrier 30 on the base 10. For example, the self-locking structure 20 can be locked to fix the carrier 30 on the base 10, and the self-locking structure 20 can also be opened to facilitate the carrier 30 to detach from the base 10.

[0080] The adapter structure refers to a structure on the carrier 30 that is mainly used to cooperate with the self-locking structure 20. When the self-locking structure 20 is locked, the self-locking structure 20 can fix the adapter structure and thereby fix the carrier 30. When the self-locking structure 20 is opened, the adapter structure can be detached from the self-locking structure 20 to allow the carrier 30 to detach from the base 10.

[0081] When the self-locking structure 20 locks the adapter structure, the carrier 30 can be fixed on the base 10; for example, after the carrier 30 is placed at a preset position on the base 10, the self-locking structure 20 locks the adapter structure to fix the carrier 30, and at this time the carrier 30 is not easy to move relative to the base 10; wherein, the preset position of the carrier 30 on the base 10 is the installation position of the carrier 30.

[0082] The cooperation between the self-locking structure 20 and the adapter structure can be achieved in a variety of ways; in some embodiments, the self-locking structure 20 is a rotary clamping cylinder, and the adapter structure is a plate-like structure. When the self-locking structure 20 is locked, it can press the adapter structure to fix the carrier 30, and when the self-locking structure 20 is opened, it can be detached from the adapter structure; in other embodiments, the self-locking structure 20 is an electromagnet, and the adapter structure is a magnet. When the self-locking structure 20 is locked, the electromagnet is energized and absorbs the magnet to fix the carrier 30, and when the self-locking structure 20 is opened, the electromagnet is de-energized, and the adapter structure can be detached from the self-locking structure 20; in some other embodiments, the self-locking structure 20 can be a buckle, and the adapter structure is a card body. When the self-locking structure 20 is locked, it can be clamped on the card body to fix the carrier 30, and when the self-locking structure 20 is opened, it can be detached from the card body; it can be understood that the self-locking structure 20 and the adapter structure can also be other structures and cooperate with each other, not limited to the above-mentioned ones.

[0083] The self-locking structure 20 cooperates with the adapting structure to fix the bearing member 30 to the base 10 , and in this case, there is no need to set additional bolts to fix the bearing member 30 ; when the bearing member 30 needs to be replaced, it is only necessary to open the self-locking structure 20 .

[0084] In this embodiment, the self-locking structure 20 cooperates with the adapting structure of the carrier 30 to fix the carrier 30 on the base 10. When the heating device 100 needs to be replaced, it is only necessary to open the self-locking mechanism and close the self-locking structure 20 after replacing the carrier 30. Compared with the method of loosening and tightening multiple nuts, this setting simplifies the replacement steps and improves the replacement efficiency.

[0085] refer to Figure 1 , Figure 2 In some embodiments, the heating device 100 further includes a heating component 60 disposed on the base 10 . The heating component 60 may be disposed on opposite sides of the carrier 30 to heat the battery placed on the carrier 30 .

[0086] refer to Figures 3 to 6 In some embodiments, the self-locking structure 20 includes a driving member 21 disposed on the base 10 and a clamping arm 22 connected to the driving member 21, and the driving member 21 is used to drive the clamping arm 22 to press on the adapting structure.

[0087] The clamping arm 22 refers to a structure in the self-locking structure 20 that is mainly used to press the adapter structure. The clamping arm 22 can be pressed on the adapter structure to fix the adapter structure, thereby fixing the carrier 30; the clamping arm 22 can also be separated from the adapter structure to facilitate the carrier 30 to be separated from the base 10; the shape of the clamping arm 22 can be cylindrical, prismatic or other columnar structures, the shape of the clamping arm 22 can also be a rectangular plate, an elliptical plate or a plate-like structure of other shapes, the clamping arm 22 can also be L-shaped, U-shaped or other irregular shapes; the material of the clamping arm 22 can include metal, plastic or other materials.

[0088] The driving member 21 refers to a structure in the self-locking structure 20 that is mainly used to drive the clamping arm 22 to move; the driving member 21 can drive the clamping arm 22 to move in a straight line, for example, along the height direction (Z) of the heating device 100, or along other directions. The driving member 21 can also drive the clamping arm 22 to rotate relative to the driving member 21. The driving member 21 can also drive the clamping arm 22 to rotate while moving in a straight line.

[0089] The driving component 21 may include a cylinder, a hydraulic cylinder or other driving components. The driving component 21 may also include a worm gear with a motor, a multi-link with a motor and other structures; the driving component 21 may be connected to the base 10 by screwing, clamping, etc., or by welding, gluing, etc.

[0090] There may be a variety of ways in which the driving member 21 drives the clamping arm 22 to press the adapting structure. In some embodiments, the driving member 21 may drive the clamping arm 22 to contract so that the clamping arm 22 presses the adapting structure onto the housing of the driving member 21. In other embodiments, the driving member 21 may drive the clamping arm 22 to rotate or extend, in which case the adapting structure may be a groove structure, and the clamping arm 22 may be pressed onto the inner wall of the groove structure after movement. It is understandable that the clamping arm 22 may also be pressed onto the adapting structure in other ways, not limited to the above two ways.

[0091] In this embodiment, the driving member 21 drives the clamping arm 22 to press the adapting structure to achieve the effect of locking the adapting structure and fixing the bearing member 30 .

[0092] refer to Figures 3 to 6 In some embodiments, the adapting structure includes a pressing portion 301 connected to the supporting member 30 , and the pressing portion 301 is disposed on a side of the supporting member 30 facing the base 10 ; the clamping arm 22 is used to press on the pressing portion 301 .

[0093] The pressing portion 301 refers to a structure on the carrier 30 that is mainly used to be pressed by the clamping arm 22; the pressing portion 301 can be a plate-like structure, such as a circular plate, a square plate or other plate structures, and the pressing portion 301 can also be other shapes; the pressing portion 301 can be integrally formed with the carrier 30, and can also be connected to the carrier 30 by welding, bonding, screwing, etc.; the material of the pressing portion 301 and the carrier 30 can be the same or different, and the material of the pressing portion 301 can include metal, plastic or other materials.

[0094] The pressing portion 301 is arranged on the side of the carrier 30 facing the base 10. Since the pressing portion 301 is used to cooperate with the clamping arm 22, this arrangement can reduce the situation where the pressing portion 301 and the clamping arm 22 protrude from the surface of the carrier 30 away from the base 10, thereby reducing the situation where the battery collides with the pressing portion 301 or the clamping arm 22 during the process of being placed on the carrier 30, and can also reduce the negative impact on the stability of the carrier 30 carrying the battery.

[0095] There are many ways for the clamping arm 22 to press the pressing portion 301. For example, when the supporting member 30 is placed at a preset position on the base 10, the pressing portion 301 can be located below the clamping arm 22. At this time, the clamping arm 22 can move downward under the drive of the driving member 21 and press the pressing portion 301 on the base 10 to fix the pressing portion 301 and further fix the supporting member 30.

[0096] In this embodiment, the pressing portion 301 is arranged on the side of the carrier 30 facing the base 10, that is, the pressing portion 301 is arranged on the side of the carrier 30 away from the battery cell; because the clamping arm 22 is used to press on the pressing portion 301, the base 10 and the clamping arm 22 need to be on opposite sides of the pressing portion 301. Providing the pressing portion 301 on the side of the carrier 30 facing the base 10 can reduce the occurrence of the clamping arm 22 or the driving member 21 protruding from the carrier 30, thereby allowing the battery to be placed on the carrier 30 more stably.

[0097] refer to Figures 3 to 6 In some embodiments, the driving member 21 can drive the clamping arm 22 to move between a first position and a second position; when the clamping arm 22 is in the first position, the clamping arm 22 is pressed on the pressing portion 301, and the orthographic projection of the clamping arm 22 on the base 10 and the orthographic projection of the pressing portion 301 on the base 10 at least partially overlap; when the clamping arm 22 is in the second position, the clamping arm 22 is separated from the pressing portion 301, and the orthographic projection of the clamping arm 22 on the base 10 and the orthographic projection of the pressing portion 301 on the base 10 are staggered.

[0098] The first position and the second position refer to two positions to which the clamping arm 22 can move, respectively. In addition to the first position and the second position, the driving member 21 can also drive the clamping arm 22 to move to other positions, not limited to the first position and the second position.

[0099] The orthographic projection of the clamping arm 22 on the base 10 refers to the projection formed by the projection line of the clamping arm 22 being perpendicular to the base 10 , and the orthographic projection of the pressing portion 301 on the base 10 refers to the projection formed by the projection line of the pressing portion 301 being perpendicular to the base 10 .

[0100] When the clamping arm 22 is in the first position, the clamping arm 22 can be pressed on the pressing portion 301, and can press the pressing portion 301 on the outer shell of the driving member 21 to fix the pressing portion 301, that is, when the clamping arm 22 is in the first position, the self-locking structure 20 is in a locked state; at this time, the orthographic projection of the clamping arm 22 and the base 10 and the orthographic projection of the pressing portion 301 on the base 10 at least partially overlap, that is, the clamping arm 22 can be above the pressing portion 301 to facilitate pressing the pressing portion 301.

[0101] When the clamping arm 22 is in the second position, the clamping arm 22 is separated from the pressing portion 301 and does not contact the pressing portion 301, so as to facilitate the disassembly and replacement of the carrier 30, that is, the self-locking structure 20 is in an open state when the clamping arm 22 is in the second position; at this time, the orthographic projection of the clamping arm 22 on the base 10 is staggered with the orthographic projection of the pressing portion 301 on the base 10, that is, the clamping arm 22 and the pressing portion 301 are staggered, so as to facilitate the removal of the carrier 30.

[0102] In this embodiment, the clamping arm 22 has a first position and a second position. The clamping arm 22 can press the holding portion 301 against the driving member 21 in the first position to fix the carrier 30. The clamping arm 22 can also be separated from the holding portion 301 and interlaced with the holding portion 301 in the second position to reduce interference with the disassembly of the carrier 30, so that the carrier 30 can be removed more conveniently.

[0103] refer to Figures 3 to 6 In some embodiments, a through hole is opened on the carrier 30, the pressing portion 301 is connected to the inner wall of the through hole, and the clamping arm 22 is rotatably accommodated in the through hole; when the clamping arm 22 is in the first position, the clamping arm 22 is above the pressing portion 301 and pressed on the pressing portion 301; when the clamping arm 22 is in the second position, the clamping arm 22 is staggered with the pressing portion 301 to reduce the obstruction of the clamping arm 22 to the carrier 30.

[0104] In some embodiments, the self-locking structure 20 includes a driving member 21 disposed on the base 10 and at least two abutting fingers (not shown in the figure) connected to the driving member 21. The driving member 21 is used to drive at least two abutting fingers to move closer to or away from each other so that the abutting fingers abut or detach from the supporting member 30.

[0105] The abutting finger refers to the structure in the self-locking structure 20 that is mainly used to abut the carrier 30; the abutting finger can be a columnar structure, such as a cylindrical, prism-shaped or other columnar structure, and the abutting finger can also be a sheet structure or a structure of other shapes; the material of the abutting finger can include metal, plastic or other materials; there can be two, three or more abutting fingers.

[0106] The driving member 21 refers to the structure in the self-locking structure 20 that is mainly used to drive the movement of the supporting finger; the driving member 21 may include a cylinder, a hydraulic cylinder or other driving members, and the driving member 21 may also include a worm gear with a motor, a multi-link with a motor and other structures; the driving member 21 may be connected to the base 10 by means of screw connection, clamping connection, etc., and may also be connected to the base 10 by means of welding, gluing, etc.

[0107] The abutting fingers are arranged on the driving member 21 and driven by the driving member 21. The driving member 21 can drive the abutting fingers to move closer to each other or away from each other. For example, the abutting fingers move closer to each other and can clamp the carrier 30 between the abutting fingers to fix the carrier 30. At this time, the abutting fingers move away from each other and can be detached from the carrier 30 to facilitate the disassembly and replacement of the carrier 30. It can be understood that the abutting fingers can also fix the carrier 30 in other ways.

[0108] This embodiment provides other specific structures of the self-locking structure 20 , where the driving member 21 drives at least two abutting fingers to clamp the carrier 30 , thereby achieving the effect of fixing the carrier 30 .

[0109] In some embodiments, the adapting structure includes a clamping hole, which is opened on the side of the carrier 30 facing the base 10; at least part of the abutting finger extends into the clamping hole, and the abutting finger is used to abut the inner wall of the clamping hole.

[0110] The holding hole refers to a hole structure formed on the carrier 30, and the holding hole is mainly used to accommodate the holding finger and provide the holding finger with abutment; the holding hole can be a blind hole or a through hole; the holding hole can be a circular hole, a square hole or a hole of other shapes.

[0111] Since at least a portion of the abutting finger can extend into the holding hole and the self-locking structure 20 is disposed on the side of the carrier 30 facing the base 10 , the holding hole is opened on the side of the carrier 30 facing the base 10 .

[0112] The holding finger may only partially extend into the holding hole, or may be entirely accommodated in the holding hole; in some embodiments, the inner diameter of the holding hole may be larger than the width of the driving member 21. When the supporting member 30 is placed at a preset position of the base 10, the holding hole is opposite to the driving member 21. At this time, the supporting member 30 is not easy to apply pressure to the driving member 21, thereby being able to protect the driving member 21.

[0113] The driving member 21 can drive at least two abutting fingers to move away from each other so as to abut against the inner wall of the clamping hole. The abutting fingers abutting against the inner wall of the clamping hole can limit the movement of the supporting member 30 on the base 10, thereby playing the role of fixing the supporting member 30; at the same time, the driving member 21 applies pressure to the inner wall of the clamping hole through the abutting fingers to increase the friction between the abutting fingers and the inner wall of the clamping hole, thereby making it difficult for the supporting member 30 to be removed from the base 10, further playing the role of fixing the supporting member 30.

[0114] The driving member 21 can also drive at least two abutting fingers to approach each other so as to break away from the inner wall of the clamping hole, thereby facilitating the disassembly and replacement of the carrier 30 .

[0115] In this embodiment, a clamping hole is opened on the carrier 30 so that the abutting finger can be abutted against the inner wall of the clamping hole, thereby achieving the function of fixing the carrier 30; at the same time, this arrangement can reduce the occurrence of the abutting finger protruding from the carrier 30, so that the battery can be placed on the carrier 30 more stably.

[0116] refer to Figure 2 , Figure 3 , Fig. 9 In some embodiments, the heating device 100 further includes a first support member 32 disposed on the carrier 30 , and the first support member 32 is used to support the base 10 .

[0117] The first support member 32 refers to a structure mainly used to support the carrier 30; the first support member 32 can be a columnar structure, for example, a cylindrical, polygonal column or other columnar structure, the first support member 32 can also be a frame structure, such as a "door" type frame, an "H" type frame or other frame structure, the first support member 32 can also be other shapes; the material of the first support member 32 can include metal, plastic or other materials; the number of first support members 32 can be one, or two or more.

[0118] The first support member 32 is disposed on the carrier 30 . The first support member 32 can be disposed on the carrier 30 by screw connection, clamping connection, etc., or by welding, bonding, etc.

[0119] The first support member 32 is used to support the base 10. When the carrier 30 is placed at a preset position on the base 10, the first support member 32 is placed on the base 10 to support the carrier 30 so that the carrier 30 can be placed on the base 10 more stably. At the same time, it can also reduce the pressure on the self-locking structure 20 and protect the self-locking structure 20.

[0120] In this embodiment, the first support member 32 is supported on the base 10 and connected to the bearing member 30 , so that the bearing member 30 is supported by the first support member 32 , thereby reducing the pressure on the self-locking structure 20 and improving the stability and service life of the self-locking structure 20 .

[0121] refer to Figure 2 , Figure 3 , Figures 7 to 10 In some embodiments, a receiving groove 321 is formed on the first support member 32 ; the heating device 100 further includes a support block 40 disposed on the base 10 , the support block 40 is received in the receiving groove 321 and abuts against the inner wall of the receiving groove 321 .

[0122] The receiving groove 321 refers to a groove structure opened on the first support member 32 . The receiving groove 321 may be a square groove, or a semicircular groove, a trapezoidal groove, or a groove of other shapes.

[0123] The support block 40 refers to a structure in the heating device 100 that is mainly used to limit the displacement of the first support member 32. The accommodating groove 321 can be accommodated in the accommodating groove 321, and the outer wall of the support block 40 can abut against the inner wall of the accommodating groove 321; when the supporting member 30 is placed at the preset position of the base 10, the accommodating groove 321 is opposite to the support block 40. When the supporting member 30 is placed at the preset position of the base 10, the support block 40 is accommodated in the accommodating groove 321.

[0124] The outer wall of the support block 40 abuts against the inside of the accommodating groove 321, which can limit the displacement of the first support member 32 on the base 10, so that the carrier 30 can be more stably located on the base 10; at the same time, the pressure borne by the carrier 30 along the height direction (Z) and the width direction (Y) of the heating device 100 can be transmitted to the support block 40 through the carrier 30 and the first support member 32. At this time, the support block 40 can also play a certain supporting role on the first support member 32 and the carrier 30, so as to share the pressure on the carrier 30 and reduce the pressure on the self-locking structure 20, thereby protecting the self-locking structure 20.

[0125] For example, when the carrier 30 is subjected to pressure from the width direction (Y) of the heating device 100, the pressure will form a displacement tendency between the carrier 30 and the first support member 32. At this time, the outer wall of the support block 40 abuts against the inner wall of the accommodating groove 321 to limit and suppress the displacement tendency and provide support for the first support member 32. That is, at this time, the pressure can partially act on the support block 40 to reduce the pressure acting on the self-locking structure 20, thereby protecting the self-locking structure 20.

[0126] Since the support block 40 can abut against the inner wall of the receiving groove 321 after being received in the receiving groove 321 , the shape of the support block 40 should be the same or substantially the same as the shape of the receiving groove 321 , so that the support block 40 can better provide support for the first support member 32 .

[0127] In this embodiment, the pressure on the carrier 30 is shared by the support block 40; at the same time, the support block 40 can also limit the horizontal displacement of the carrier 30. When the carrier 30 is subjected to horizontal pressure, the support block 40 can provide support for the carrier 30 through the first support member 32, thereby reducing the pressure on the self-locking structure 20 and protecting the self-locking structure 20.

[0128] refer to Figure 2 , Figure 3 , Figures 7 to 10 In some embodiments, the support block 40 tapers in a direction away from the base 10 .

[0129] The support block 40 gradually shrinks in a direction away from the base 10, that is, the size of the support block 40 gradually decreases along the height direction (Z) of the heating device 100 toward the direction away from the base 10; wherein, only the width of the support block 40 can be gradually reduced, that is, only the size of the support block 40 in the width direction (Y) of the heating device 100 can be gradually reduced, or only the length of the support block 40 can be gradually reduced, that is, only the size of the support block 40 in the length direction (X) of the heating device 100 can be gradually reduced, or both the width and length of the support block 40 can be gradually reduced.

[0130] When the pressure on the supporting member 30 is applied to the supporting block 40 through the first supporting member 32, this arrangement can enable the pressure to generate a component force along the direction of gravity and a component force along the horizontal direction. The component force in the direction of gravity can be transmitted to the base 10 or the ground supporting the base 10. At this time, the supporting block 40 only needs to suppress the movement trend generated by the component force in the horizontal direction.

[0131] At the same time, this arrangement can also guide the placement of the first support member 32 , so that the first support member 32 can be placed at a preset position of the base 10 .

[0132] For example, the size of the support block 40 in the width direction (Y) of the heating device 100 is gradually reduced in the direction from the base 10 to the direction away from the base 10; this arrangement enables the support member 30 to be subjected to pressure along the width direction (Y) of the heating device 100 and act on the support block 40 through the first support member 32. The pressure can generate a component force on the first support block 40 toward the base 10. At this time, the support block 40 only needs to suppress the movement trend generated by the component force in the width direction (Y).

[0133] In this embodiment, the support block 40 is gradually reduced in a direction away from the base 10 so that the support block 40 can be more easily clamped in the receiving groove 321 during the installation of the carrier 30, and the support block 40 can better suppress the movement tendency of the first support member 32 and the carrier 30.

[0134] refer to Figure 2 , Fig. 9 In some embodiments, the heating device 100 further includes a second support member 33 disposed on the carrier 30 , and the second support member 33 is used to support the base 10 .

[0135] The second support member 33 refers to a structure mainly used to support the carrier 30; the second support member 33 can be a columnar structure, for example, a cylindrical, polygonal column or other columnar structure, the second support member 33 can also be a frame structure, such as a "door" type frame, an "H" type frame or other frame structure, the second support member 33 can also be other shapes; the material of the second support member 33 can include metal, plastic or other materials.

[0136] The number of second support members 33 may be one, or two or more; for example, there are multiple second support members 33, and the multiple second support members 33 are spaced apart along the length direction of the carrier 30, so that the carrier 30 can be placed on the base 10 more stably, and the carrier 30 can also carry the battery more stably.

[0137] The second support member 33 is disposed on the carrier 30 . The second support member 33 can be disposed on the carrier 30 by screw connection, clamping connection, etc., or by welding, bonding, etc.

[0138] The second support member 33 is used to support the base 10. When the carrier 30 is placed at a preset position on the base 10, the second support member 33 is placed on the base 10 to support the carrier 30 so that the carrier 30 can be placed on the base 10 more stably. At the same time, it can also reduce the pressure on the self-locking structure 20 and protect the self-locking structure 20.

[0139] In the technical solution of this embodiment, the second support member 33 is supported on the base 10 and connected to the carrier 30, so that the carrier 30 is supported by the second support member 33, thereby reducing the pressure on the self-locking structure 20 and improving the stability and service life of the self-locking structure 20.

[0140] refer to Figure 4 , Figures 7 to 10 In some embodiments, an identification structure 31 is provided on the carrier 30 ; the heating device 100 further includes an identification device 50 provided on the base 10 , and the identification device 50 is used to identify the identification structure 31 .

[0144] The identification device 50 refers to a device in the heating device 100 that is mainly used to identify the identification structure 31. The identification device 50 can obtain and identify the shape of the identification structure 31, and can also obtain and identify the position of the identification structure 31; the identification device 50 can include a camera, and can also include structures such as a signal transmission unit and an analysis unit.

[0145] Because the heating device 100 provided in this embodiment can replace carriers 30 of different specifications so that carriers 30 of different specifications can carry batteries of different specifications, and because the heating device 100 requires different heating standards for batteries of different specifications; accordingly, setting identification structures 31 of different shapes or positions on carriers 30 of different specifications can facilitate the heating device 100 to correspond carriers 30 of different specifications with corresponding heating standards, so as to facilitate heating treatment of batteries of different specifications that meets their heating standards.
