[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202510005442.3, filed on January 2, 2025, entitled “A Battery Clamp and Baking Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of battery heating technology, and more particularly to a battery clamp and baking device. Background Technology

[0004] During battery manufacturing, moisture can accumulate inside the battery. Therefore, heating is necessary to remove this moisture, thereby improving battery performance and safety. However, in related technologies, the battery clamp consumes a significant amount of heat during heat transfer, resulting in low thermal conversion efficiency. Summary of the Invention

[0005] This disclosure provides a battery clamp and a baking device that can improve the thermal conversion efficiency of the battery clamp.

[0006] This disclosure provides a battery clamp, which includes a clamping member and a heating plate. The clamping member has a receiving space for placing a battery. The bottom of the clamping member has a hollow portion that communicates with the receiving space. The heating plate is placed at the bottom of the clamping member and contacts the battery in the receiving space through the hollow portion.

[0007] The battery clamp provided in this disclosure includes a clamping member and a heating plate. The clamping member has a receiving space for placing a battery. The bottom of the clamping member has a hollow portion that communicates with the receiving space. Thus, when the battery is placed in the receiving space, the bottom of the battery can be exposed through the hollow portion. When the clamping member is placed on the heating plate, the heating plate can contact the battery in the receiving space through the hollow portion, directly transferring the heat generated by the heating plate to the battery. Compared with related technologies where the heating plate heats the battery through a fixed block, the battery clamp provided in this disclosure has a hollow portion at the bottom of the clamping member that communicates with the receiving space. This allows the heating plate to directly transfer heat to the battery through the hollow portion, shortening the heat conduction path, reducing heat loss during the transfer process, and thus improving the thermal conversion efficiency of the battery clamp.

[0008] In some embodiments of this disclosure, a support portion is provided at the bottom of the accommodating space. The support portion is used to support the battery in the corresponding accommodating space. The support portions are spaced apart to form a hollow portion.

[0009] In some embodiments of this disclosure, the heating plate is formed with a protrusion, and when the clamping member is placed on the heating plate, the upper surface of the protrusion is not lower than the upper surface of the support, and the protrusion passes through the hollow portion and contacts the battery in the corresponding receiving space.

[0015] In some embodiments of this disclosure, the limiting spacer is a plate-like structure, and the contour block has a slot, which is used to fix the contour block to the top of the limiting spacer.

[0016] In some embodiments of this disclosure, multiple limiting spacers are evenly spaced along a first direction, with the limiting spacers located on the inner wall of the frame adjacent to the corresponding side.

[0017] In some embodiments of this disclosure, the heating plate includes a housing, a first heating component, and a second heating component. The housing has a heating surface for placing a support member. The heating surface includes a central region and an edge region surrounding the central region. The first heating component and the second heating component are disposed in the housing. The first heating component is disposed corresponding to the central region to provide heat energy to the central region, and the second heating component is disposed corresponding to the edge region to provide heat energy to the edge region. The heating power of the second heating component is greater than the heating power of the first heating component.

[0018] In some embodiments of this disclosure, the central region includes a first region and a second region, and the first heating component includes a first heating element and a second heating element. The first heating element is disposed corresponding to the first region to provide heat energy to the first region, and the second heating element is disposed corresponding to the second region to provide heat energy to the second region.

[0019] In some embodiments of this disclosure, along a first direction, the ratio between the size of the central region and the size of the heating surface is greater than or equal to 0.85 and less than or equal to 0.95; and / or, along a second direction, the ratio between the size of the central region and the size of the heating surface is greater than or equal to 0.85 and less than or equal to 0.95, wherein the first direction is perpendicular to the second direction.

[0020] In some embodiments of this disclosure, the heating plate has a first positioning block and a second positioning block spaced apart along a second direction, and the clamping member has a first limiting plate and a second limiting plate spaced apart along a second direction; when the clamping member is placed on the heating plate, the first positioning block and the second positioning block are located between the first limiting plate and the second limiting plate, and the first positioning block is stopped by the first limiting plate, and the second positioning block is stopped by the second limiting plate.

[0021] In some embodiments of this disclosure, the frame has a limiting rod, the first end of which is connected to a first limiting plate, and the second end of which is connected to a second limiting plate.

The first direction is the length direction of the battery clamp, which is also the spacing direction of the limiting spacers 2; the second direction is the width direction of the battery clamp, which is also the extension direction of the limiting spacers 2; and the third direction is the height direction of the battery clamp. It should be noted that the direction markings are for description purposes only and are not intended to limit the scope of this disclosure.

[0048] Batteries are increasingly used in daily life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. As the application areas of batteries continue to expand, the market demand for them is also constantly increasing.

[0049] During battery manufacturing, moisture can accumulate inside the battery. Therefore, heating is necessary to remove this moisture, thereby improving battery performance and safety. In related technologies, battery clamps include a heating plate and a fixing block, with the fixing block having holes for placing the battery. When heating the battery, the fixing block is placed on the heating plate, which heats the fixing block and transfers heat to the battery in the corresponding hole. However, this process results in the fixing block consuming a significant amount of heat, leading to low thermal conversion efficiency of the battery clamp.

[0050] This disclosure addresses the problems existing in the aforementioned related technologies by proposing a battery clamp. Referring to Figures 1, 2, and 3, the battery clamp includes a clamping member 1 and a heating plate 2. The clamping member 1 forms a receiving space 11 for placing a battery 3. The bottom of the clamping member 1 has a hollow portion 12 that communicates with the receiving space 11. The clamping member 1 is placed on the heating plate 2, and the heating plate 2 contacts the battery 3 in the receiving space 11 through the hollow portion 12.

[0051] In this embodiment of the disclosure, the function of the accommodating space 11 is to place the battery 3. Therefore, the shape design of the accommodating space 11 has many possibilities. For example, the accommodating space 11 can be rectangular, circular, or irregular in shape. This embodiment of the disclosure does not limit this.

[0052] In this embodiment, the function of the cutout portion 12 is to expose the battery 3 placed in the receiving space 11, so that the heating plate 2 can contact the battery 3 in the receiving space 11 through the cutout portion 12. Therefore, the structural design of the cutout portion 12 has many possibilities. For example, the cutout portion 12 can be a circular hole, a strip hole, or an irregularly shaped hole structure. This embodiment does not limit the design of the cutout portion 12.

[0053] In the technical solution provided by this embodiment, the battery clamp includes a clamping member 1 and a heating plate 2. The clamping member 1 has a receiving space 11 for placing a battery 3. The bottom of the clamping member 1 has a hollow portion 12 that communicates with the receiving space 11. Thus, when the battery 3 is placed in the receiving space 11, the bottom of the battery 3 can be exposed through the hollow portion 12. When the clamping member 1 is placed on the heating plate 2, the heating plate 2 can contact the battery 3 in the receiving space 11 through the hollow portion 12, so as to directly transfer the heat generated by the heating plate 2 to the battery 3.

[0054] Compared with the related technologies in which the heating plate 2 heats the battery 3 through a fixed block, in the battery clamp provided in this disclosure, the bottom of the clamping member 1 has a hollow part 12 that communicates with the accommodating space 11, so that the heating plate 2 can directly transfer heat to the battery 3 through the hollow part 12, shortening the heat conduction path, reducing the heat loss during the transfer process, and thus improving the heat conversion efficiency of the battery clamp.

[0055] In this embodiment, when the battery 3 needs to be moved, the clamping member 1 and the heating plate can be moved simultaneously, or the clamping member 1 can be moved alone; this embodiment does not limit this. When moving the clamping member 1 alone, to prevent the battery 3 from falling out of the receiving space 11 through the cutout 12, the size of the cutout 12 can be smaller than the size of the battery, or the inner wall of the receiving space 11 can be in close contact with the outer peripheral surface of the battery 3, so as to use the friction of the inner wall of the receiving space 11 to provide support for the battery 3.

[0056] Referring to Figure 1, in one possible embodiment of this disclosure, a support portion 141 is provided at the bottom of the receiving space 11. The support portion 141 is used to support the battery 3 in the corresponding receiving space 11. The support portions are spaced apart to form a hollow portion. In this way, when it is necessary to move the battery 3, the support portion 141 can provide support for the battery 3 in the corresponding receiving space 11, so that only the clamping member 1 can be moved when moving the battery 3, which facilitates the movement of the battery 3 and improves the flexibility of the battery clamp when using it.

[0057] In this embodiment of the disclosure, when the heating plate 2 contacts the battery 3 in the accommodating space 11 through the hollow part 12, the structural design of the heating plate 2 can be varied. For example, the side of the heating plate 2 where the clamping member 1 is placed can be a plane, and the size of the hollow part 12 is larger than the area of ​​the bottom of the battery 3. When the clamping member 1 is placed on the heating plate 2, the bottom of the battery 3 contacts the heating plate 2 through the hollow part 12.

[0058] Referring to Figure 1, in one possible embodiment of this disclosure, the heating plate 2 has a protrusion 212. When the clamping member 1 is placed on the heating plate 2, the upper surface of the protrusion 212 is not lower than the upper surface of the support portion 141. The protrusion 212 passes through the hollow portion 12 and contacts the battery 3 in the corresponding receiving space 11. In this way, when the clamping member 1 has the support portion 141, the protrusion 212 can pass through the hollow portion 12 and contact the battery 3 in the corresponding receiving space 11, so that there is sufficient contact area between the heating plate 2 and the battery 3, thereby improving the heating efficiency of the heating plate 2 on the battery 3.

[0059] In this embodiment of the present disclosure, referring to FIG1, the clamping member 1 includes a frame 13 and limiting spacers 14. At least two limiting spacers 14 are spaced apart in the frame 13 along a first direction, and an accommodating space is formed between two adjacent limiting spacers 14. The ends of the limiting spacers 14 are connected to the frame 13, and the support portion 141 is disposed at the bottom of the limiting spacers 14. At least two rows of protrusions 212 are spaced apart along the first direction. The protrusions 212 are used to contact the battery 3 through the gap between the support portions 141 of two adjacent limiting spacers 14.

[0060] In this embodiment of the disclosure, the shape design of the frame 13 can be various. For example, the shape of the frame 13 can be a rectangle, a circle, or a triangle. This embodiment of the disclosure does not limit this.

[0061] In this embodiment, the frame 13 can serve to fix the limiting spacer 14. Referring to Figure 4, when the limiting spacer 14 is disposed within the frame 13, the end of the limiting spacer 14 can be integrally connected to the frame 13, such as by welding or integral molding; or, the end of the limiting spacer 14 can also be movably connected to the frame 13, such as by snap-fit ​​or fastener connection. This embodiment does not impose any limitations on this. It should be noted that when the end of the limiting spacer 14 is movably connected to the frame 13, the distance between two adjacent limiting spacers 14 can be adjusted by changing the connection position of the limiting spacer 14 within the frame 13 to accommodate batteries 3 of different sizes, thereby improving the flexibility of the battery clamp.

[0062] In this embodiment, the number of limiting spacers 14 within the frame 13 can be varied. For example, two limiting spacers 14 can be spaced apart within the frame 13; or five limiting spacers 14 can be spaced apart within the frame 13; or even twenty limiting spacers 14 can be spaced apart within the frame 13. The number of limiting spacers 14 within the frame 13 can be set as needed, and this embodiment does not impose any limitations on this.

[0063] In this embodiment, the function of the support portion 141 is to provide support for the battery 3. Therefore, the structure of the support portion 141 can be varied. For example, the support portion 141 can be a strip structure, and the extension direction of the support portion 141 is consistent with that of the limiting spacer 14; or, the support portion 141 can also be a block structure, and multiple support portions 141 are provided at intervals in the extension direction of the limiting spacer 14. This embodiment does not limit the scope of the support portion 141.

[0064] In this embodiment, the space between two adjacent spacer bars 14 serves as a place for the battery 3. Therefore, along the first direction, the distance between two adjacent spacer bars 14 needs to be greater than or equal to the size of the battery 3 to be placed. In addition, to improve the utilization rate of the accommodating space, along the extension direction of the spacer bars 14, i.e., the second direction, as shown in Figure 4, multiple batteries 3 can be arranged and placed in the same accommodating space.

[0065] In this embodiment, the function of the spaced support portions 141 of the two adjacent limiting spacers 14 is to avoid the battery 3, so that the protrusion 212 of the heating plate 2 can contact the battery 3 through the gap between the support portions 141 of the two adjacent limiting spacers 14, so that the heat generated by the heating plate 2 can be directly transferred to the battery 3 through the protrusion 212.

[0066] In this embodiment, the contact form between the protrusion 212 and the battery 3 can be varied. For example, the contact between the protrusion 212 and the battery 3 can be surface contact or line contact, and this embodiment does not limit this. It should be noted that when the contact between the protrusion 212 and the battery 3 is surface contact, the contact area between the protrusion 212 and the battery 3 can be increased, thereby improving the heat conduction efficiency.

[0067] In the technical solution provided by this embodiment, the clamping member includes a frame 13 and limiting spacers 14. The frame 13 provides a fixing base for the limiting spacers 14. At least two limiting spacers 14 are spaced apart along a first direction within the frame 13. The ends of the limiting spacers 14 are connected to the frame 13, so that the limiting spacers 14 divide the frame 13 to form receiving spaces 11 for placing the battery 3. The bottom of the limiting spacer 14 has a support portion 141 for placing the battery 3 in the corresponding receiving space 11. The battery 3 provides support; the heating plate 4 has a heating surface 411 for placing the limiting spacers 14 to heat the battery 3 placed between adjacent limiting spacers 14; the support portions 141 of adjacent limiting spacers 14 are spaced apart to form a gap for avoiding the battery 3; protrusions 212 are formed on the heating surface 411, and at least two rows of protrusions 212 are spaced apart along a first direction, the number of protrusions 212 being the same as the number of hollow portions 12, so that the protrusions 212 correspond one-to-one with the hollow portions 12. In this way, when heating the battery 3, the battery 3 can be placed between adjacent limiting spacers 14 first, and then the clamp holding the battery 3 can be placed on the heating surface 411. At this time, the protrusions 212 contact the battery 3 through the gap between the support portions 141 of adjacent limiting spacers 14. Here, the adjacent limiting spacers 14, while forming a space 11 for accommodating the battery 3, can also reduce the overall weight of the clamp holding 1, thereby facilitating the handling of the clamp holding 1.

[0068] In this embodiment of the present disclosure, when the battery 3 is placed in the accommodating space 11, in order to improve the stability of the battery 3, the distance between two adjacent limiting spacers 14 along the first direction is the same as the size of the battery 3, so that when the battery 3 is placed between two adjacent limiting spacers 14, the outer peripheral surface of the battery 3 can fit with the corresponding limiting spacer 14, thereby limiting the battery 3.

[0069] It should be noted that, to improve the limiting effect on the battery 3, the side of the limiting spacer 14 that is used to contact the battery 3 can be matched with the outer peripheral surface of the battery 3. For example, when the outer peripheral surface of the battery 3 is a convex arc, the side of the limiting spacer 14 can be a concave arc. This increases the contact area between the limiting spacer 14 and the battery 3, thereby improving the limiting effect on the battery 3.

[0070] Referring to Figures 2 and 3, in one possible embodiment of this disclosure, the clamping member 1 further includes a contour block 15 connected to the limiting spacer 14. The contour block 15 has an adaptation notch 151 for fitting against the outer peripheral surface of the battery 3 placed between two adjacent limiting spacers 14. Thus, when the battery 3 is placed in the receiving space, the adaptation notch 151 of the contour block 15 can fit against the outer peripheral surface of the battery 3, thereby limiting the battery 3 and reducing the probability of the battery 3 shaking.

[0071] In this embodiment of the disclosure, the clamping member 1 can be applied to prismatic batteries (such as long blade batteries, short blade batteries, etc.) or cylindrical batteries. This embodiment of the disclosure does not limit the application to either.

[0072] In this embodiment of the disclosure, the function of the adapter notch 151 is to fit against the outer peripheral surface of the battery 3 in the accommodating space. Therefore, the shape design of the adapter notch 151 has a variety of possibilities. For example, referring to FIG3, when the battery 3 is a cylindrical battery, the shape of the adapter notch 151 can be an arc shape; referring to FIG12, when the battery 3 is a square battery, the shape of the adapter notch 151 can be a rectangle. This embodiment of the disclosure does not limit this.

[0073] In this embodiment, the location of the adapter notch 151 on the contour block 15 can be varied. For example, along the first direction, the adapter notch 151 can be provided only on one side of the contour block 15. Referring to Figures 2 and 3, in one possible embodiment of this disclosure, along the first direction, the adapter notch 151 is located on opposite sides of the contour block 15 to respectively conform to the outer peripheral surface of the corresponding battery 3. Here, with the adapter notch 151 located on opposite sides of the contour block 15 in the first direction, the contour block 15 can simultaneously limit the position of the batteries 3 in the accommodating spaces on both sides. In this way, under the condition of limiting a certain number of batteries 3, the number of contour blocks 15 can be reduced, thereby reducing the overall weight of the battery clamp and lowering the production cost of the battery clamp.

[0074] Referring to Figures 2, 3, and 4, in this embodiment of the present disclosure, multiple adapter notches 151 are evenly spaced along the second direction, with the first direction perpendicular to the second direction. Thus, when multiple batteries 3 are arranged in the second direction, the adapter notches 151 can individually limit the movement of each battery 3, reducing the probability of interference between adjacent limiting spacers 14 due to shaking. It should be noted that the number of adapter notches 151 in the second direction can be the same as the number of batteries 3 arranged in the second direction, so that each adapter notch 151 corresponds one-to-one with a battery 3.

[0075] Referring to Figures 2, 3 and 4, in this embodiment of the present disclosure, the number of fitting notches 151 along the second direction can be various. For example, the number of fitting notches 151 along the second direction can be three, six or eight. This embodiment of the present disclosure does not limit this.

[0076] In this embodiment of the disclosure, along the second direction, the distance between two adjacent adapter notches 151 may be the same or different, and this embodiment of the disclosure does not impose any limitation on this. In addition, the distance between the inner wall of the frame 13 and the corresponding adapter notch 151 may be greater than the distance between two adjacent adapter notches 151 or less than the distance between two adjacent adapter notches 151, and this embodiment of the disclosure also does not impose any limitation on this.

[0077] Referring to Figures 4 and 5, in this embodiment of the present disclosure, along the second direction, the distance 'a' between the inner wall of the frame 13 and the corresponding end adapter notch 151 is greater than the distance 'b' between two adjacent adapter notches 151. Thus, when heating the battery 3, because the distance 'a' between the inner wall of the frame 13 and the corresponding end adapter notch 151 is greater than the distance 'b' between two adjacent adapter notches 151, the heat transfer from the battery 3 at the corresponding end adapter notch 151 to the frame 13 can be reduced, thereby improving the heating efficiency of the battery 3.

[0078] In this embodiment of the disclosure, the function of the limiting spacer 14 is to divide the space within the frame 13 to form a space for placing the battery 3. Therefore, the structural design of the limiting spacer 14 has many possibilities. For example, the limiting spacer 14 can be a plate-shaped structure, a block-shaped structure, or a rod-shaped structure. This embodiment of the disclosure does not limit this.

[0079] In this embodiment of the disclosure, the contour block 15 can be set at the limiting spacer 14 in various ways. For example, the contour block 15 can be integrally set at the limiting spacer 14, or the contour block 15 can be detachably set at the limiting spacer 14, such as by snap-fit ​​or fastener connection. This embodiment of the disclosure does not limit this.

[0080] Referring to Figures 2 and 3, in one possible embodiment of this disclosure, the limiting spacer 14 has a plate-like structure, and the contour block 15 has a slot 152. The contour block 15 is fixed to the top of the limiting spacer 14 by engaging the slot 152. Here, the limiting spacer 14 has a plate-like structure, which simplifies the structural design of the limiting spacer 14 and facilitates its processing and manufacturing. The contour block 15 has a slot 152, which is used to fix the top of the limiting spacer 14. Here, the top of the limiting spacer 14 forms a mating part that engages with the slot 152, eliminating the need for separate processing of the limiting spacer 14 and simplifying the processing steps of the limiting spacer 14. The engagement between the contour block 15 and the limiting spacer 14 makes disassembly and assembly more convenient and improves the efficiency of disassembly and assembly of the contour block 15. In addition, the contour block 15 and the limiting spacer 14 are designed to be detachable. When heating different types of batteries 3, only the contour block 15 needs to be replaced, without having to replace the limiting spacer 14 at the same time. This improves the compatibility of the battery clamp and reduces the cost of using the battery clamp.

[0081] In this embodiment of the disclosure, the contact position between the protrusion 212 and the battery 3 can be various. For example, when the protrusion 212 contacts the battery 3, the protrusion 212 can contact the bottom of the battery 3, or it can contact the outer peripheral surface of the battery 3, or it can contact both the bottom and the outer peripheral surface of the battery 3 at the same time. This embodiment of the disclosure does not limit this.

[0082] In this embodiment of the disclosure, the protrusion 212 can be in direct contact with the battery 3 or indirect contact with the battery 3. For example, a buffer pad can be provided on the side of the protrusion 212 facing the battery 3 to reduce the probability of the battery 3 being damaged when the protrusion 212 contacts the battery 3.

[0083] Referring to Figures 2 and 3, in one possible embodiment of this disclosure, along a third direction, the size of the protrusion 212 is the same as the size of the support portion 141. When the limiting spacer 14 is placed on the heating surface, the height of the protrusion 212 is flush with the height of the support portion 141, so that the protrusion 212 contacts the bottom of the battery 3. The first direction is perpendicular to the third direction. Because the size of the protrusion 212 is the same as the size of the support portion 141, when the limiting spacer 14 is placed on the heating surface, the protrusion 212 extends into the gap between the support portions 141 of two adjacent limiting spacers 14 and becomes flush with the height of the support portion 141, so that the protrusion 212 and the support portion 141 jointly contact the bottom of the battery 3. In this way, the protrusion 212 does not occupy space, allowing more batteries 3 to be placed between two adjacent limiting spacers 14, thus improving space utilization.

[0084] In this embodiment of the disclosure, the structure of the protrusion 212 can be varied. For example, multiple protrusions 212 can be spaced apart in the second direction, or the protrusions 212 can be arranged continuously in the second direction. This embodiment of the disclosure does not limit this.

[0085] Referring to Figures 2 and 3, in one possible embodiment of this disclosure, both the protrusion 212 and the support portion 141 extend along a second direction. Along the first direction, the dimensions of the protrusion 212 and the support portion 141 are the same. Along the second direction, the dimensions of the protrusion 212 and the support portion 141 are the same. The first, second, and third directions are perpendicular to each other. Thus, when the limiting spacer 14 is placed at the heating surface 411, the protrusion 212 can fit snugly into the gap between the support portions 141 of two adjacent limiting spacers 14, maximizing the contact area between the protrusion 212 and the bottom of the battery 3, further improving heat conduction efficiency.

[0086] Referring to Figures 2 and 4, in this embodiment of the present disclosure, multiple spacer bars 14 are evenly spaced along the first direction, and the spacer bars 14 are located adjacent to the corresponding sides of the inner wall of the frame 13. Here, the evenly spaced multiple spacer bars 14 allow at least two rows of batteries 3 to be placed within the frame 13 along the first direction, enabling the heating plate 4 to simultaneously heat at least two rows of batteries 3, thus improving the heating efficiency of the batteries 3. The spacer bars 14 located adjacent to the corresponding sides of the inner wall of the frame 13 reduce wasted space within the frame 13, thereby increasing the number of spacer bars 14 arranged within the frame.

[0087] In this embodiment, when the limiting spacer 14 is placed on the heating plate 4, the frame 13 can be placed on the heating plate 4 or suspended in mid-air; this embodiment does not impose any restrictions on this. It should be noted that when the limiting spacer 14 is placed on the heating plate 4, the frame 13 being suspended in mid-air avoids direct contact between the frame 13 and the heating plate 4, thereby reducing the heat loss from the heating plate 2 and helping to improve the evenness of heating the battery 3.

[0088] In this embodiment, the heating plate 4 has a first portion and a second portion surrounding the first portion. The first portion is used to place the limiting spacer 14, and the second portion is used to place the frame 13. Thus, when heating the battery 3, the first portion of the heating plate 4 can provide support for the limiting spacer 14, and the second portion of the heating plate 4 can provide support for the frame 13, improving the reliability of the battery clamp.

[0089] Referring to Figures 1 and 8, in this embodiment of the present disclosure, the limiting spacer 14 is fixedly disposed within the frame 13. The limiting spacer 14 is typically moved through the frame 13. To facilitate the handling of the limiting spacer 14, support plates 14 are provided on opposite sides of the frame 13 in the second direction. Furthermore, to reduce the weight of the support plates 14, weight-reducing holes 115 can be provided at the support plates 114. Referring to Figures 2, 3, and 5, in this embodiment of the present disclosure, the heating plate 2 includes a housing 21, a first heating component (not shown in the figures), and a second heating component (not shown in the figures). The housing 21 has a heating surface 211 for placing the clamping member 1. The heating surface 211 includes a central region 2111 and an edge region 2112 surrounding the central region 2111. The first heating component and the second heating component are disposed in the housing 21. The first heating component is disposed corresponding to the central region 2111 to provide heat energy to the central region 2111, and the second heating component is disposed corresponding to the edge region 2112 to provide heat energy to the edge region 2112. The heating power of the second heating component is greater than that of the first heating component.

[0090] In this embodiment, the heating surface 211 serves to house the battery clamp for heating the battery 3 placed between two adjacent limiting spacers 14. The shape of the heating surface 211 can be varied; for example, it can be rectangular, circular, or triangular. This embodiment does not impose any limitations on this. It should be noted that the shape of the heating surface 211 can be the same as the shape of the frame 13, for example, both the heating surface 211 and the frame 13 can be circular; the shape of the heating surface 211 can also be different from the shape of the frame 13, for example, the heating surface 211 can be rectangular and the frame 13 can be circular. This embodiment also does not impose any limitations on this.

[0091] In this embodiment of the disclosure, the function of the first heating element and the second heating element is to generate heat. Therefore, the structural forms of the first heating element and the second heating element are various possibilities. For example, the first heating element and the second heating element can be electric heating wires, ceramic heating elements, or quartz tube heating elements. This embodiment of the disclosure does not limit these.

[0092] In this embodiment of the disclosure, the outer shell 21 not only accommodates the first heating component and the second heating component, but also needs to conduct the heat generated by the first heating component and the second heating component to the heating surface 211. Therefore, the material of the outer shell 21 needs to have thermal conductivity, such as aluminum, steel, copper, etc. This embodiment of the disclosure does not limit this.

[0093] In the technical solution provided by this embodiment, the heating plate 2 includes a housing 21, a first heating component, and a second heating component. The first and second heating components are disposed within the housing 21 to provide heat to the heating surface 211 of the housing 21. The heating surface 211 includes a central region 2111 and an edge region 2112 surrounding the central region 2111. The first heating component is disposed corresponding to the central region 2111 to heat the battery 3 located in the central region 2111, and the second heating component is disposed corresponding to the edge region 2112 to heat the battery 3 located in the edge region 2112. When the heating plate 2 heats the battery 3, the battery clamp frame 13 consumes some of the heat from the edge region 2112 of the heating plate 2, resulting in a significant temperature difference between the edge region 2112 and the central region 2111 of the heating plate 2, thus affecting the uniformity of heating the battery 3. The heating power of the second heating component is greater than that of the first heating component. In this way, the extra heat generated by the second heating component compared to the first heating component can be consumed by the frame 13, thereby reducing the temperature difference between the edge region 2112 and the center region 2111 of the heating plate 2 and improving the uniformity of heating the battery 3.

[0094] It should be noted that, in this embodiment of the present disclosure, when the first heating component and the second heating component are heating wires, the density of the heating wires at the first heating component and the second heating component can be designed based on factors such as the specific heat capacity of the material, the total mass, and the highest temperature of the metal structural components around the battery clamp. For example, the total heat absorbed by the metal structural components around the battery clamp can be calculated first using the material heat absorption calculation formula Q = cmΔT (Q is the heat absorbed by the material, c is the specific heat capacity of the material, m is the mass of the material, and ΔT is the temperature difference between the initial temperature and the final temperature of the material). Then, the required heating power of the first heating component and the second heating component can be determined based on the total heat absorbed by the metal structural components around the battery clamp. For example, the difference between the heat output of the second heating component and the heat output of the first heating component can be equal to the total heat absorbed by the metal structural components around the battery clamp, so as to reduce the temperature difference between the edge region 2112 of the heating plate 2 and the center region 2111 of the heating plate 2. Finally, according to R = U 2 The resistances of the first and second heating components are calculated using the formula / P (where R is the resistance of the heating component, P is the heating power of the heating component, and U is the voltage), thereby determining the arrangement density of the heating wires at the first and second heating components.

[0095] Referring to Figure 2, in this embodiment of the present disclosure, the heating plate 2 is provided with a power taking component 25, and the heating plate 2 is electrically connected to the power supply device through the power taking component 25 to provide power to the first heating component and the second heating component.

[0096] Referring to Figure 6, in this embodiment of the present disclosure, the central region 2111 includes a first region 21111 and a second region 21112. The first heating component includes a first heating element and a second heating element. The first heating element is disposed corresponding to the first region 21111 to provide heat energy to the first region 21111, and the second heating element is disposed corresponding to the second region 21112 to provide heat energy to the second region 21112. Here, the central region 2111 includes the first region 21111 and the second region 21112, and the first heating component includes the first heating element and the second heating element. The first heating element is used to heat the battery 3 in the first region 21111, and the second heating element is used to heat the battery 3 in the second region 21112. The central region 2111 is divided into the first region 21111 and the second region 21112, so that the first heating element and the second heating element can correspond to a smaller heating area, which is beneficial to improving the control accuracy of the first heating component.

[0097] In this embodiment of the disclosure, the area of ​​the first region 21111 can be the same as, larger than or smaller than, the area of ​​the second region 21112, and this embodiment of the disclosure does not impose any restrictions on this. When the areas of the first region 21111 and the second region 21112 are the same, the heating power of the first heating element and the second heating element can be the same, so as to minimize the temperature difference between the first region 21111 and the second region 21112, thereby improving the uniformity of heating the battery 3; when the area of ​​the first region 21111 is larger than the area of ​​the second region 21112, the heating power of the first heating element can be greater than the heating power of the second heating element, so as to reduce the temperature difference between the first region 21111 and the second region 21112, thereby improving the uniformity of heating the battery 3; when the area of ​​the first region 21111 is smaller than the area of ​​the second region 21112, the heating power of the first heating element can be less than the heating power of the second heating element, so as to reduce the temperature difference between the first region 21111 and the second region 21112, thereby improving the uniformity of heating the battery 3.

[0098] Referring to Figure 7, in this embodiment of the present disclosure, the edge region 2112 may include a third region 21121 and a fourth region 21122. The second heating component includes a third heating element and a fourth heating element. The third heating element is disposed corresponding to the third region 21121 to provide heat energy to the third region 21121, and the fourth heating element is disposed corresponding to the fourth region 21122 to provide heat energy to the fourth region 21122. The edge region 2112 is divided into the third region 21121 and the fourth region 21122, so that the third heating element and the fourth heating element can correspond to a smaller heating area, which is beneficial to improving the control accuracy of the second heating component.

[0099] In this embodiment of the disclosure, the area of ​​the third region 21121 may be the same as, larger than or smaller than, the area of ​​the fourth region 21122. This embodiment of the disclosure does not impose any restrictions on this. When the areas of the third region 21121 and the fourth region 21122 are the same, the heating power of the third heating element and the fourth heating element can be the same, so as to minimize the temperature difference between the third region 21121 and the fourth region 21122, thereby improving the uniformity of heating the battery 3; when the area of ​​the third region 21121 is larger than the area of ​​the fourth region 21122, the heating power of the third heating element can be greater than the heating power of the fourth heating element, so as to reduce the temperature difference between the third region 21121 and the fourth region 21122, thereby improving the uniformity of heating the battery 3; when the area of ​​the third region 21121 is smaller than the area of ​​the fourth region 21122, the heating power of the third heating element can be less than the heating power of the fourth heating element, so as to reduce the temperature difference between the third region 21121 and the fourth region 21122, thereby improving the uniformity of heating the battery 3.

[0100] In this embodiment of the disclosure, the ratio between the size of the central region 2111 and the size of the heating surface can be various. For example, along the first direction, the ratio between the size of the central region 2111 and the size of the heating surface can be 0.7, 0.75, or 0.8; along the second direction, the ratio between the size of the central region 2111 and the size of the heating surface can be 0.7, 0.75, or 0.8. This embodiment of the disclosure does not limit this.

[0101] In one possible embodiment of this disclosure, along a first direction, the ratio between the size of the central region 2111 and the size of the heating surface 211 is greater than or equal to 0.85 and less than or equal to 0.95; and / or, along a second direction, the ratio between the size of the central region 2111 and the size of the heating surface 211 is greater than or equal to 0.85 and less than or equal to 0.95, wherein the first direction is perpendicular to the second direction.

[0102] It should be noted that, in this embodiment of the present disclosure, the ratio between the size of the central region 2111 and the size of the heating surface 211 may be greater than or equal to 0.85 and less than or equal to 0.95 only along the first direction; or, the ratio between the size of the central region 2111 and the size of the heating surface 211 may be greater than or equal to 0.85 and less than or equal to 0.95 only along the second direction; or, the ratio between the size of the central region 2111 and the size of the heating surface may be greater than or equal to 0.85 and less than or equal to 0.95 in both the first and second directions.

[0103] In addition, in this embodiment of the present disclosure, along the first direction, the ratio between the size of the central region 2111 and the size of the heating surface 211 can be 0.85, 0.9, or 0.95; along the second direction, the ratio between the size of the central region 2111 and the size of the heating surface can be 0.85, 0.9, or 0.95, and this embodiment of the present disclosure does not impose any restrictions on this.

[0104] In the technical solution provided by this disclosure, along the first and second directions, the ratio between the size of the central region 2111 and the size of the heating surface 211 is greater than or equal to 0.85 and less than or equal to 0.95, and / or the ratio between the size of the central region 2111 and the size of the heating surface 211 is greater than or equal to 0.85 and less than or equal to 0.95. This allows the central region 2111 to occupy a larger proportion of the heating surface 211, which is beneficial for improving the consistency of heat generation in different areas of the heating surface 211, thereby improving the uniformity of heating the battery 3.

[0105] In this embodiment, when the limiting spacer 14 is placed at the heating plate 2, the protrusion of the heating plate 2 needs to enter the corresponding hollow portion 12. To improve the fitting accuracy between the limiting spacer 14 and the heating plate 2, referring to Figures 8, 9, and 10, the heating plate 2 has a first positioning block 22 and a second positioning block 23 spaced apart along the second direction, and the frame 13 has a first limiting plate 131 and a second limiting plate 12 spaced apart along the second direction. The first positioning block 22 is used to stop and cooperate with the first limiting plate 131 along the second direction, and the second positioning block 23 is used to stop and cooperate with the second limiting plate 12 along the second direction. In this way, during the process of placing the limiting spacer 14 at the heating surface 211, the first positioning block 22 stops and cooperates with the first limiting plate 131, and the second positioning block 23 stops and cooperates with the second limiting plate 12, so that the limiting spacer 14 and the heating plate 2 can be aligned and cooperated in the second direction, thereby improving the fitting accuracy between the limiting spacer 14 and the heating plate 2.

[0106] To further improve the fitting accuracy between the limiting spacer 14 and the heating plate 2, referring to Figures 8, 9, and 10, a limiting rod 13 is also provided at the frame 13. The first end of the limiting rod 13 is connected to the first limiting plate 131, and the second end of the limiting rod 13 is connected to the second limiting plate 12. The first positioning block 22 is provided with a first positioning groove 221, and the second positioning block 23 is provided with a second positioning groove 231. The limiting rod 13 is used to engage with the first positioning groove 221 and the second positioning groove 231. In this way, during the process of placing the limiting spacer 14 at the heating surface 211, the first positioning block 22 and the first limiting plate 131 engage with each other in the second direction, the second positioning block 23 and the second limiting plate 12 engage with each other in the second direction, and the limiting rod 13 engages with both the first positioning groove 221 and the second positioning groove 231. This allows the limiting spacer 14 and the heating plate 2 to be aligned and engaged in the first and second directions, further improving the fitting accuracy between the limiting spacer 14 and the heating plate 2.

[0107] In this embodiment, to ensure smooth engagement between the first positioning block 22 and the first limiting plate 131, and between the second positioning block 23 and the second limiting plate 12, referring to Figures 8, 9, and 10, the first positioning block 22 is provided with a first guide surface 222, and the second positioning block 23 is provided with a second guide surface 232. Thus, when the battery clamp is placed on the heating surface 211, in the second direction, the first positioning block 22, guided by the first guide surface 222, engages with the first limiting plate 131, and the second positioning block 23, guided by the second guide surface 232, engages with the second limiting plate 12.

[0108] In this embodiment, to ensure smooth engagement between the limiting rod 13 and the first positioning groove 221 and the second positioning groove 231, referring to Figure 10, a third guide surface 223 is provided at the opening of the first positioning groove 221, and a fourth guide surface 233 is provided at the opening of the second positioning groove 231. Thus, when the limiting spacer 14 is placed at the heating surface 211, the limiting rod 13 simultaneously engages with the first positioning groove 221 and the second positioning groove 231 under the action of the third guide surface 223 and the fourth guide surface 233.

[0109] Based on this, the present disclosure also provides a baking apparatus, which further includes a baking oven and a battery clamp. The baking oven has a baking cavity, and the battery clamp is used to place the battery 3 in the baking cavity for baking.

[0110] In this embodiment of the disclosure, the battery clamp can be installed in the baking cavity in various ways. For example, the battery clamp can be installed integrally in the baking cavity or it can be detachably installed in the baking cavity. This embodiment of the disclosure does not limit this.

[0111] In this embodiment of the disclosure, the number of battery clamps in the baking cavity can be varied. For example, one, three, or five battery clamps can be provided in the baking cavity. This embodiment of the disclosure does not limit this.

[0112] In this embodiment of the disclosure, the baking cavity serves to accommodate the battery clamp. Therefore, the shape of the baking cavity can be varied. For example, the baking cavity can be a circular cavity or a rectangular cavity. This embodiment of the disclosure does not limit this.

[0113] The baking apparatus provided in this embodiment of the present disclosure, since it includes the battery clamp of this embodiment, also has the same technical effect. That is, it can improve the heat conversion efficiency of the battery clamp.

[0114] The above embodiments are merely illustrative of the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
