[0002] This disclosure is based on and claims priority to Chinese Patent Application No. 202423096527.7, filed on December 13, 2024, the contents of which are hereby incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of vacuum coating technology, and more particularly to a carrier. Background Technology

[0004] In the production process of photovoltaic cells, the carrier is the core component that supports the transportation and processing of the substrate, and its design directly affects production efficiency and process quality. Summary of the Invention

[0005] This disclosure provides a carrier including a frame and multiple inner frame strips. The inner frame strips are disposed within the frame, and their ends are connected to the frame. The inner frame strips are intersecting in the plane of the frame to form multiple support holes for accommodating a substrate. Each inner frame strip has a support protrusion located within the support hole. Along the circumference of the support hole, multiple support protrusions within the same support hole are sequentially arranged, and the upper end face of the multiple support protrusions is used to support the substrate, so that the substrate is accommodated within the support hole.

[0006] In the carrier provided in this embodiment, the frame provides installation space for the inner frame strips through the above-described configuration. Multiple inner frame strips are intersected within the plane of the frame to form multiple support holes, thus forming the carrier. Since multiple support protrusions located within the support holes are formed on the inner frame strips, the substrate can be placed on the upper surface of the support protrusions to support it, thereby achieving synchronous transport of the carrier and the substrate. Because the support holes for accommodating the substrate are directly formed by the intersection of multiple inner frame strips, and the support protrusions for supporting the substrate are directly formed on the inner frame strips, the carrier structure in this disclosure is simple, and its processing and assembly are relatively convenient.

[0007] In one possible implementation of this disclosure, the upper end face of the bearing protrusion is an inclined surface, the inclined surface forms an acute angle with the axis of the bearing hole, and along the axis of the bearing hole, the inclined surface is close to the edge of the center line of the bearing hole and lower than the edge of the inclined surface away from the center line of the bearing hole.

[0008] This allows the substrate to make line contact with the inclined surface. During the transport process, the substrate and the inclined surface experience line friction, which reduces the wear on the lower surface of the substrate.

[0009] In one possible implementation of this disclosure, the edge of the inclined surface away from the center line of the bearing hole is flush with the upper surface of the inner frame strip. The carrier also includes a limiting member disposed on the upper surface of the inner frame strip, along the edge of the inclined surface away from the center line of the bearing hole, and avoiding the bearing hole; the limiting member is connected to the inner frame strip.

[0010] With the above configuration, since the limiting member is set along the edge of the inclined surface away from the center line of the bearing hole, when the substrate is placed on the inclined surface, the limiting member can limit the substrate and prevent the substrate from moving out of the inclined surface, so that the substrate is stably set in the bearing hole.

[0011] In one possible implementation of this disclosure, the limiting member includes multiple limiting protrusions along the edge of the inclined surface away from the center line of the bearing hole, and the multiple limiting protrusions are arranged sequentially at intervals.

[0012] By setting the limiting component to a structure of multiple limiting protrusions, since the multiple limiting protrusions are arranged sequentially and spaced apart along the edge of the inclined surface away from the center line of the bearing hole, the normal function of the limiting protrusions can be guaranteed, and the material used for the limiting component can be reduced, thus reducing material costs.

[0013] In one possible implementation of this disclosure, multiple intersecting inner frame strips form multiple intersection positions. Each intersection position is formed by the intersection of two inner frame strips, including a first inner frame strip and a second inner frame strip. The first and second inner frame strips are sequentially arranged along a direction perpendicular to the plane of the frame. At the intersection position, the second inner frame strip has a clearance groove on the side opposite to the first inner frame strip. Along the extending direction of the first inner frame strip, the clearance groove penetrates the second inner frame strip, and a portion of the first inner frame strip extends into the clearance groove.

[0014] This design not only facilitates the assembly of the first and second inner frame strips, but also allows the upper surfaces of the first and second inner frame strips to be on the same plane by reasonably setting the depth of the clearance groove. This makes the surface of the grid structure composed of multiple inner frame strips flat, which facilitates the setting of the protrusion and the placement of the substrate.

[0015] In one possible implementation of this disclosure, the carrier further includes a crimping member disposed at an intersection. The crimping member includes a connecting portion and a pressing portion. Along the arrangement direction of the first inner frame strip and the second inner frame strip, the connecting portion passes through the first inner frame strip and is connected to the second inner frame strip. The pressing portion is connected to the end of the connecting portion away from the second inner frame strip and abuts against the first inner frame strip. The pressing portion avoids the bearing hole.

[0016] With the above configuration, the crimping part is connected to the first inner frame strip and the second inner frame strip through the connecting part. Due to the presence of the pressing part, the pressing part can press the first inner frame strip onto the second inner frame strip. In this way, during the transportation of the vehicle, the relative stability between the first inner frame strip and the second inner frame strip can be ensured, the vibration frequency between the first inner frame strip and the second inner frame strip can be reduced, thereby ensuring the overall structural stability of the vehicle.

[0017] In one possible implementation of this disclosure, the first inner frame strip has a receiving groove on the side opposite to the second inner frame strip, and the pressing part is located in the receiving groove.

[0018] By setting a receiving groove on the first inner frame strip, the receiving groove can provide a receiving space for the pressing part. By reasonably setting the groove depth, the upper surface of the pressing part is made close to or flush with the upper surface of the first inner frame strip, so as to avoid the presence of the pressing part affecting the surface flatness of the entire vehicle.

[0019] In one possible implementation of this disclosure, the ends of the inner frame strips are connected to the frame via a first mortise and tenon structure; and / or, the frame includes a plurality of outer frame strips connected end to end in sequence, with adjacent outer frame strips connected via a second mortise and tenon structure.

[0020] This ensures a smooth connection between the inner frame strip and the outer frame, while also simplifying the connection and ensuring high stability. And / or, this ensures a smooth connection between adjacent outer frame strips, while also simplifying the connection and ensuring high stability.

[0021] In one possible implementation of this disclosure, the carrier further includes connectors. A connector is provided at the corner where the inner frame strip connects to the outer frame, and the connector is connected to both the outer frame and the inner frame strip; and / or, a connector is provided at the corner of the outer frame, and the connector is connected to both outer frame strips of the outer frame at the corner.

[0022] With the above configuration, at the corner where the inner frame strip connects to the frame, the connector can be connected to both the frame and the inner frame strip, thereby increasing the structural strength at the corner where the inner frame strip connects to the frame. And / or, the connector can be connected to the two outer frame strips of the frame at the corner, thereby increasing the structural strength at the corner.

[0023] In one possible implementation of this disclosure, the plurality of inner frame strips includes a plurality of first inner frame strips and a plurality of second inner frame strips. The plurality of first inner frame strips are arranged at intervals along a first direction and extend along a second direction. The plurality of second inner frame strips are arranged at intervals along the second direction and extend along the first direction, the first direction intersecting the second direction. The plurality of first inner frame strips and the plurality of second inner frame strips are intersected to form a plurality of bearing holes.

[0024] With the above arrangement, multiple first inner frame strips and multiple second inner frame strips are arranged in an array. This allows for the placement of more inner frame strips within the limited space inside the frame, facilitating the placement of more substrates and increasing the substrate load-bearing capacity per unit area of ​​the carrier. Furthermore, this arrangement of the first and second inner frame strips also simplifies their production and carrier assembly, reducing the processing difficulty of the carrier.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the specific technical solutions of this disclosure will be further described in detail below with reference to the accompanying drawings of the embodiments of this disclosure. The following embodiments are used to illustrate this disclosure, but are not intended to limit the scope of this disclosure.

[0043] In the embodiments of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0044] Furthermore, in the embodiments of this disclosure, directional terms such as "up," "down," "left," and "right" are defined relative to the orientation in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation in which the components are placed in the accompanying drawings.

[0045] In the embodiments disclosed herein, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0046] In embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] In the production process of solar cells, the substrate is transferred between multiple processing stations. To facilitate the transportation of the substrate, it is usually placed on a carrier, which then passes through multiple processing stations in sequence. At each processing station, the substrate on the carrier is processed to ultimately form a solar cell.

[0049] In related technologies, the carrier consists of two parts: a metal frame and a metal carrier plate. Specifically, the metal frame includes a border and a metal wire mesh grid disposed inside it. The metal carrier plate is placed on the metal wire mesh grid, and then grooves are machined on the metal carrier plate to support the substrate. Because this type of carrier consists of two parts, a metal frame and a metal carrier plate, its structure is complex, and its processing and assembly are also relatively complicated.

[0050] Based on this, as shown in Figures 1 to 3, this disclosure provides a carrier 01, which includes a frame 1 and a plurality of inner frame strips 2. The plurality of inner frame strips 2 are disposed within the frame 1, and the ends of the inner frame strips 2 are connected to the frame 1. The plurality of inner frame strips 2 are intersecting in the plane of the frame 1 to form a plurality of bearing holes a, which are used to accommodate a substrate 02. The plurality of inner frame strips 2 have bearing protrusions 21 located within the bearing holes a. Along the circumference of the bearing holes a, the plurality of bearing protrusions 21 within the same bearing hole a are arranged sequentially, and the upper end face 21a of the plurality of bearing protrusions 21 is used to support the substrate 02 so that the substrate 02 is accommodated within the bearing holes a.

[0051] It is understandable that the "up" and "down" of the carrier 01 refer to the side of the carrier 01 facing away from the conveyor line after it is placed on the conveyor line, which is the "up" side and the side of the carrier 01 facing towards the conveyor line, which is the "down" side. Based on this, the substrate 02 is located on the upper side of the carrier 01, so the upper end surface 21a of the bearing protrusion 21 is the surface of the bearing protrusion 21 facing away from the conveyor line.

[0052] The outer contour of border 1 can be a regular shape such as a circle or a square. Of course, the outer contour of border 1 can also be an irregular shape.

[0053] Furthermore, the material of the frame 1 can be composite material, metal, or plastic. For example, composite material can be carbon fiber, and the carbon fiber frame 1 has advantages such as high structural strength, light weight, and corrosion resistance. The material of the inner frame strip 2 can also be composite material, metal, or plastic. For example, composite material can be carbon fiber, and the carbon fiber inner frame strip 2 has advantages such as high structural strength, light weight, and corrosion resistance.

[0054] In some examples, any two adjacent bearing protrusions 21 within the same bearing hole a can be in contact with each other along the circumference of the bearing hole a. Of course, multiple bearing protrusions 21 within the same bearing hole a can be spaced apart along the circumference of the bearing hole a. The number of bearing protrusions 21 within the same bearing hole a can be two, three, or four, etc., depending on the specific requirements.

[0055] In some examples, the carrier hole a can be a regular shape such as a circular hole or a square hole, or it can be an irregularly shaped space, as long as it can accommodate the substrate 02.

[0056] In some examples, along the extension direction of the bearing hole a, the size of the bearing protrusion 21 is the same as the size of the inner frame strip 2 on which it is located; that is, along the extension direction of the bearing hole a, the bearing protrusion 21 extends from one end of the inner frame strip 2 on which it is located to the other end.

[0057] Of course, along the extension direction of the bearing hole a, the size of the bearing protrusion 21 can also be smaller than the size of the bearing hole a.

[0058] In some examples, the supporting protrusion 21 and the inner frame strip 2 are integrally formed, which not only ensures the structural strength between the supporting protrusion 21 and the inner frame strip 2, but also avoids secondary processing.

[0059] In some examples, the cross-section of the inner frame strip 2 perpendicular to its extension direction can be a regular shape such as a square or a circle, or it can be an irregular shape.

[0060] With the above configuration, the frame 1 provides installation space for the inner frame strips 2. Multiple inner frame strips 2 are intersected in the plane of the frame 1 to form multiple support holes a, thereby forming the carrier 01. Since multiple support protrusions 21 located in the support holes a are formed on the inner frame strips 2, the substrate 02 can be supported by placing it on the upper end face 21a of the support protrusions 21, thereby achieving synchronous transportation of the carrier 01 and the substrate 02.

[0061] Since the bearing hole a for accommodating the substrate 02 is directly formed by the intersection of multiple inner frame strips 2, and the bearing protrusion 21 for supporting the substrate 02 is directly formed on the inner frame strips, the carrier 01 in this disclosure has a simple structure and is relatively easy to process and assemble.

[0062] To facilitate the processing of the carrier 01 and to accommodate more substrates 02, the cross arrangement of the multiple inner frame strips 2 needs to be specifically designed.

[0063] In some embodiments, as shown in Figures 1 to 3, the plurality of inner frame strips 2 include a plurality of first inner frame strips 2A and a plurality of second inner frame strips 2B. The plurality of first inner frame strips 2A are arranged at intervals along a first direction X and extend along a second direction Y. The plurality of second inner frame strips 2B are arranged at intervals along the second direction Y and extend along the first direction X, where the first direction X intersects with the second direction Y. The plurality of first inner frame strips 2A and the plurality of second inner frame strips 2B are intersected to form a plurality of bearing holes a.

[0064] It is understandable that the distance between adjacent first inner frame strips 2A should be determined based on the size of the substrate 02 in the first direction X. Similarly, the distance between adjacent second inner frame strips 2B should be determined based on the size of the substrate 02 in the second direction Y. Furthermore, it is known that a bearing hole a is formed by two first inner frame strips 2A and two second inner frame strips 2B.

[0065] In some examples, the angle between the first direction X and the second direction Y can be 80°, 90°, 100° or 110°, etc.

[0066] In some examples, as shown in Figures 1-3, the first direction X is perpendicular to the second direction Y. The frame 1 has a square structure and includes four outer frame strips 11 connected end-to-end. Each outer frame strip 11 includes two opposing first outer frame strips 11A and two opposing second outer frame strips 11B. The first outer frame strips 11A extend along the first direction X, and the second outer frame strips 11B extend along the second direction Y. The first outer frame strips 11A and second outer frame strips 11B are perpendicular to each other. In this way, the entire carrier 01 has a square mesh shape, and the overall structure is regularized, which facilitates the production, processing, and assembly of the frame 1 and the inner frame strips 2.

[0067] In some examples, the dimensions of the first inner frame strip 2A and the second inner frame strip 2B may be the same or different along the extension direction of the bearing hole a.

[0068] With the above arrangement, multiple first inner frame strips 2A and multiple second inner frame strips 2B are arranged in an array. This allows for the placement of more inner frame strips 2 within the limited space inside the frame 1, facilitating the placement of more substrates 02 and increasing the substrate 02 load-bearing capacity per unit area of ​​the carrier 01. Furthermore, this arrangement of the first inner frame strips 2A and second inner frame strips 2B also reduces the manufacturing difficulty of the carrier 01, simplifying its production and assembly.

[0069] Of course, multiple inner frame bars 2 can also be intersected in any other suitable way.

[0070] For ease of illustration, the accompanying drawings in this disclosure will be illustrated using an example of multiple inner frame strips 2 including a first inner frame strip 2A and a second inner frame strip 2B, with the first direction X and the second direction Y being perpendicular.

[0071] After the substrate 02 is placed on the support protrusion 21, in order to ensure that the substrate 02 is stably positioned within the support hole a, the surface on the support protrusion 21 used to support the substrate 02 can be an inclined surface or a plane, etc. This will be described in detail below.

[0072] In some embodiments, as shown in Figures 4 and 5, the upper end surface of the bearing protrusion 21 is an inclined surface. The inclined surface forms an acute angle with the axial direction of the bearing hole a. Along the axial direction of the bearing hole a, the inclined surface is close to the edge of the center line of the bearing hole a and lower than the edge of the inclined surface that is far from the center line of the bearing hole a.

[0073] The inclined surface can be a plane. Alternatively, the inclined surface can be a curved surface; for example, it can be a downwardly concave curved surface or an upwardly convex curved surface.

[0074] In some examples, as shown in Figures 5 and 6, the inner frame strip 2 is a cuboid strip structure. The edge of the inclined surface away from the center line of the bearing hole a coincides with the upper edge of the cuboid strip structure. By reasonably setting the inclination angle of the inclined surface, after the substrate 02 is accommodated in the bearing hole a, the substrate 02 can be avoided from being placed too deep, which makes it easier to put in and take out the substrate 02.

[0075] Of course, as shown in Figure 7, the edge of the inclined surface away from the center line of the bearing hole a can also be lower than the uppermost end of the inner frame strip 2.

[0076] By setting the upper end surface 21a of the bearing protrusion 21 as an inclined surface, the substrate 02 is in line contact with the inclined surface after it is placed on the inclined surface. During the transportation process of the carrier 01, the substrate 02 and the inclined surface experience line friction. This can reduce the wear on the lower surface of the substrate 02, ensure the integrity of the substrate 02, and ensure the structural integrity of the final battery cell after the substrate 02 is coated.

[0077] Of course, in some other embodiments, as shown in FIG8, the upper end surface 21a of the bearing protrusion 21 can also be a plane, and the upper end surface 21a of the bearing protrusion 21 is lower than the uppermost end of the inner frame strip 2, so as to ensure that the substrate 02 is stably accommodated in the bearing hole a.

[0078] In some embodiments, as shown in FIG9, the edge of the inclined surface away from the center line of the bearing hole a is flush with the upper surface of the inner frame strip 2. The carrier 01 also includes a limiting member 3, which is disposed on the upper surface of the inner frame strip 2 and is disposed along the edge of the inclined surface away from the center line of the bearing hole a, and avoids the bearing hole a. The limiting member 3 is connected to the inner frame strip 2.

[0079] In some examples, a bearing hole a is formed by two first inner frame strips 2A and two second inner frame strips 2B. Each of the two first inner frame strips 2A and two second inner frame strips 2B has a bearing protrusion 21, resulting in four bearing protrusions 21 within the bearing hole a. The upper end face 21a of each bearing protrusion 21 is an inclined surface, and the edge of the inclined surface away from the center line of the bearing hole a is flush with the upper surfaces of the first inner frame strips 2A and the second inner frame strips 2B. Therefore, the limiting member 3 can be positioned along the edges of the multiple inclined surfaces away from the center line of the bearing hole a, i.e., the limiting member 3 is positioned circumferentially around the bearing hole a. In this way, when the substrate 02 is placed on the inclined surface, the presence of the limiting member 3 can limit the position of the substrate 02, thereby preventing the substrate 02 from tilting on the inclined surface and causing a large range of horizontal displacement, ensuring that the substrate 02 is stably positioned within the bearing hole a.

[0080] With the above settings, since the limiting member 3 is set along the edge of the inclined surface away from the center line of the bearing hole a, when the substrate 02 is placed on the inclined surface, the limiting member 3 can limit the substrate 02 to prevent the substrate 02 from moving out of the inclined surface, so that the substrate 02 is stably set in the bearing hole a.

[0081] Based on this, in some embodiments, as shown in FIG9, the limiting member 3 includes a plurality of limiting protrusions 31, which are arranged sequentially at intervals along the edge of the inclined surface away from the center line of the bearing hole a.

[0082] In some examples, a carrier hole a is surrounded by two first inner frame strips 2A and two second inner frame strips 2B, and the first inner frame strips 2A and the second inner frame strips 2B are perpendicular to each other. The edge of the inclined surface of a carrier protrusion 21 away from the center line of the carrier hole a corresponds to two limiting protrusions 31. The two limiting protrusions 31 are located near the two ends of the edge of the inclined surface away from the center line of the carrier hole a. Thus, the top corner of a substrate 02 corresponds to two limiting protrusions 31. In this way, the limiting protrusions 31 can limit the substrate 02 while reducing the number of limiting protrusions 31.

[0083] The limiting protrusion 31 can be a columnar structure, for example, a cylindrical structure or a square columnar structure.

[0084] By setting the limiting member 3 to a structure of multiple limiting protrusions 31, since the multiple limiting protrusions 31 are arranged sequentially and spaced apart along the edge of the inclined surface away from the center line of the bearing hole a, the normal realization of the limiting function of the limiting protrusions 31 can be guaranteed, and the material used for the limiting member 3 can be reduced, thus reducing material costs.

[0085] In other embodiments, the limiting member 3 may also extend along the edge of the inclined surface away from the center line of the bearing hole a.

[0086] In some embodiments, as shown in Figures 10 and 11, a plurality of intersecting inner frame strips 2 are formed at multiple intersection positions. Each intersection position is formed by the intersection of two inner frame strips 2, each inner frame strip 2 including a first inner frame strip 2A and a second inner frame strip 2B. Along a direction perpendicular to the plane of the frame 1, the first inner frame strip 2A and the second inner frame strip 2B are sequentially arranged. At the intersection position, the side of the second inner frame strip 2B opposite to the first inner frame strip 2A has a clearance groove b. Along the extending direction of the first inner frame strip 2A, the clearance groove b penetrates the second inner frame strip 2B, and a portion of the first inner frame strip 2A extends into the clearance groove b.

[0087] It is understandable that by setting the clearance slot b, the first inner frame strip 2A and the second inner frame strip 2B can be located in the same plane, and it will not affect the intersecting arrangement of multiple inner frame strips 2 in the plane where the frame 1 is located.

[0088] The portion of the first inner frame strip 2A that extends into the clearance groove b is in contact with the inner wall of the clearance groove b. In other words, the first inner frame strip 2A is inserted into the second inner frame strip 2B. This ensures the relative stability of the first inner frame strip 2A and the second inner frame strip 2B, thus ensuring the overall structural stability of the vehicle 01.

[0089] With the above configuration, when multiple inner frame strips 2 are arranged to intersect, the first inner frame strip 2A can be directly pressed into the clearance groove b along the groove depth direction (perpendicular to the plane where the frame 1 is located), so that the first inner frame strip 2A and the second inner frame strip 2B are arranged to intersect at the intersection position. This configuration not only facilitates the assembly of the first inner frame strip 2A and the second inner frame strip 2B, but also allows the upper end faces 21a of the first inner frame strip 2A and the second inner frame strip 2B to be located in the same plane by reasonably setting the groove depth of the clearance groove b. This makes the surface of the mesh structure composed of multiple inner frame strips 2 flat, which facilitates the setting of the support protrusion 21 and the placement of the substrate 02.

[0090] It is understandable that, since inner frame strip 2 is already connected to outer frame 1, the first inner frame strip 2A and the second inner frame strip 2B can be unconnected at the intersection. Of course, the first inner frame strip 2A and the second inner frame strip 2B can also be connected. Several schemes for connecting the first inner frame strip 2A and the second inner frame strip 2B are provided below.

[0091] In some embodiments, as shown in Figures 10 and 11, the carrier 01 further includes a crimping member 4 disposed at the intersection position. The crimping member 4 includes a connecting portion 41 and a pressing portion 42. Along the arrangement direction of the first inner frame strip 2A and the second inner frame strip 2B, the connecting portion 41 passes through the first inner frame strip 2A and is connected to the second inner frame strip 2B. The pressing portion 42 is connected to the end of the connecting portion 41 away from the second inner frame strip 2B and abuts against the first inner frame strip 2A. The pressing portion 42 avoids the bearing hole a.

[0092] It is understandable that a connecting hole is provided on the first inner frame strip 2A, and the connecting part 41 passes through the connecting hole to the first inner frame strip 2A.

[0093] In some examples, when there is a limiting protrusion 31 on the inner frame strip 2, the limiting protrusion 31 avoids the crimping member 4, which facilitates the installation and removal of the crimping member 4.

[0094] In some examples, the pressing part 42 is a plate-like structure, with its side surface abutting against the side surface of the first inner frame strip 2A. This increases the contact area and ensures the relative stability between the first inner frame strip 2A and the second inner frame strip 2B.

[0095] The connection method between the connecting part 41 and the second inner frame strip 2B can be varied.

[0096] For example, as shown in Figures 10 and 11, the connecting part 41 includes a connecting post 411, a first bolt 412, and a first nut 413. The connecting post 411 passes through the first inner frame strip 2A and extends into the second inner frame strip 2B. Along the direction perpendicular to the second inner frame strip 2B, the connecting post 411 has a first through hole d on its peripheral wall and a second through hole e on the second inner frame strip 2B. After the connecting post 411 extends into the second inner frame strip 2B, the connecting post 411 extends into the second through hole e, and the first through hole d is located in the second through hole e. The first bolt 412 passes through the first through hole d and the second through hole e. Then, the first nut 413 is connected to the tail of the first bolt 412, thereby realizing the connection between the connecting part 41 and the second inner frame strip 2B.

[0097] It should be noted that, in this case, in order to facilitate the setting of the first bolt 412, the bottom surface of the first inner frame strip 2A should be higher than the bottom surface of the second inner frame strip 2B. In this way, at the intersection, the first inner frame strip 2A can avoid the first bolt 412 and will not affect the setting of the first bolt 412.

[0098] Alternatively, the connecting part 41 may directly include a screw, such that the screw extends directly into the second inner frame strip 2B to be threadedly connected to the second inner frame strip 2B.

[0099] With the above configuration, the crimping member 4 is connected to the first inner frame strip 2A and the second inner frame strip 2B through the connecting part 41. Due to the presence of the pressing part 42, the pressing part 42 can press the first inner frame strip 2A onto the second inner frame strip 2B. In this way, during the transportation of the vehicle 01, the relative stability between the first inner frame strip 2A and the second inner frame strip 2B can be guaranteed, and the vibration frequency between the first inner frame strip 2A and the second inner frame strip 2B can be reduced, thereby ensuring the overall structural stability of the vehicle 01.

[0100] Of course, the first inner frame strip 2A and the second inner frame strip 2B can also be directly connected together by screws or other fasteners, or fixed together by adhesive.

[0101] In some embodiments, as shown in FIG10, the first inner frame strip 2A has a receiving groove c on the side opposite to the second inner frame strip 2B, and the pressing part 42 is located in the receiving groove c.

[0102] In some examples, the depth of the receiving groove c is consistent with the size of the pressing part 42 along the groove depth direction, so that when the pressing part 42 is located in the receiving groove c, the surface of the first inner frame strip 2A can be kept flat.

[0103] Of course, along the depth direction of the receiving groove c, the depth of the receiving groove c and the size of the pressing part 4 may not be the same.

[0104] In some examples, as shown in Figures 10 and 11, the receiving groove c extends through the first inner frame strip 2A along the extension direction of the second inner frame strip 2B. After the pressing part 42 is installed into the receiving groove c, a chamfer can be made on the edge of the pressing part 42 to allow it to avoid the bearing hole a. In this case, the chamfered surface on the pressing part 42 can also support the substrate 02.

[0105] By providing a receiving groove c on the first inner frame strip 2A, the receiving groove c can provide a receiving space for the pressing part 42. By reasonably setting the groove depth of the receiving groove c, the upper surface of the pressing part 42 is close to or flush with the upper surface of the first inner frame strip 2A, so as to avoid the presence of the pressing part 42 affecting the surface flatness of the entire vehicle 01.

[0106] In some embodiments, as shown in FIG12, the end of the inner frame strip 2 is connected to the frame 1 by a first tenon structure 5. This makes the connection between the inner frame strip 2 and the frame 1 flat, and the connection method is also relatively simple and the connection stability is high.

[0107] Both ends of the same inner frame strip 2 can be connected to the frame 1 via the first mortise and tenon structure 5. Alternatively, one end of the same inner frame strip 2 can be connected to the frame 1 via the first mortise and tenon structure 5.

[0108] In addition, the ends of multiple inner frame strips 2 can all be connected to the frame 1 via the first mortise and tenon structure 5. Alternatively, only some of the inner frame strips 2 can be connected to the frame 1 via the first mortise and tenon structure 5.

[0109] In some examples, as shown in Figure 12, the first mortise and tenon structure 5 includes a first protrusion 51 and a first recess 52. One of the first protrusion 51 and the first recess 52 is disposed on the end of the inner frame strip 2, and the other of the first protrusion 51 and the first recess 52 is disposed on the side frame 1. The first protrusion 51 extends into the first recess 52, thereby achieving a snap-fit ​​connection.

[0110] In some embodiments, as shown in Figures 13 and 14, the frame 1 includes a plurality of outer frame strips 11 connected end to end in sequence, and adjacent outer frame strips 11 are connected by a second tenon and mortise structure 6. This makes the connection between adjacent outer frame strips 11 flat, and the connection method is also relatively simple and the connection stability is high.

[0111] In this configuration, any two adjacent outer frame strips 11 can be connected by the second mortise and tenon structure 6. Alternatively, any two adjacent outer frame strips 11 can be connected by the second mortise and tenon structure 6.

[0112] In some examples, the border 1 enclosed by multiple outer frame strips 11 can be a regular shape such as a square or a circle, or it can be an irregular shape.

[0113] In some examples, as shown in Figures 13 and 14, the second mortise and tenon structure 6 includes a second protrusion 61 and a second recess 62. One of the second protrusion 61 and the second recess 62 is disposed on one of the two adjacent outer frame strips 11, and the other of the second protrusion 61 and the second recess 62 is disposed on the other of the two adjacent outer frame strips 11. The second protrusion 61 extends into the second recess 62, thereby achieving a snap-fit ​​connection.

[0114] In other embodiments, as shown in Figures 12-14, the ends of the inner frame strip 2 are connected to the frame 1 via a first mortise and tenon structure 5. The frame 1 includes multiple outer frame strips 11 connected end-to-end in sequence, with adjacent outer frame strips 11 connected via a second mortise and tenon structure 6. This ensures a smooth connection between the inner frame strip 2 and the frame 1, while also simplifying the connection and improving stability. Similarly, it ensures a smooth connection between adjacent outer frame strips 11, while also simplifying the connection and improving stability.

[0115] In some embodiments, as shown in Figures 12-15, the carrier 01 further includes a connector 7. A connector 7 is provided at the corner where the end of the inner frame strip 2 connects to the frame 1, and the connector 7 is connected to both the frame 1 and the inner frame strip 2. Alternatively, a connector 7 is provided at the corner of the frame 1, and the connector 7 is connected to both outer frame strips 11 of the frame 1 at the corner.

[0116] In some examples, as shown in Figures 12 to 15, the connector 7 includes a first connecting plate 71 and a second connecting plate 72 that are connected to each other. The first connecting plate 71 and the second connecting plate 72 are set at a certain angle. For the connector 7 at the corner where the end of the inner frame strip 2 and the frame 1 are connected, the corners of the first connecting plate 71 and the second connecting plate 72 are adapted to the corners where the end of the inner frame strip 2 and the frame 1 are connected. Then, the first connecting plate 71 is connected to the inner frame strip 2 that it is attached to, and the second connecting plate 72 is connected to the frame 1 that it is attached to, thereby realizing the connection setting of the connector 7.

[0117] For the connector 7 at the corner of the frame 1, the corners of the first connecting plate 71 and the second connecting plate 72 are adapted to the included angle between the adjacent outer frame strip 11 of the frame 1. Then, the first connecting plate 71 is connected to the outer frame strip 11 it is attached to, and the second connecting plate 72 is connected to the outer frame strip 11 it is attached to, thereby realizing the connection setting of the connector 7.

[0118] For example, the angle between the first connecting plate 71 and the second connecting plate 72 can be 80°, 85°, 90°, 95° or 100°, etc.

[0119] In some examples, connector 7 further includes a second bolt 73 and a second nut 74. First connecting plate 71 includes at least one second bolt 73 and at least one second nut 74, and second connecting plate 72 includes at least one second bolt 73 and at least one second nut 74. For connector 7 at the corner connecting the end of inner frame strip 2 and frame 1, the first connecting plate 71 is connected to the inner frame strip 2 by passing the second bolt 73 through the first connecting plate 71 and inner frame strip 2, and then the second nut 74 is fitted onto the tail of the second bolt 73. Similarly, the second connecting plate 72 is connected to the frame 1 by passing the second bolt 73 through the second connecting plate 72 and frame 1, and then the second nut 74 is fitted onto the tail of the second bolt 73.

[0120] Similarly, at the corner of frame 1, the first connecting plate 71 and one outer frame strip 11 of frame 1 are connected by passing the second bolt 73 through the first connecting plate 71 and then fitting the second nut 74 onto the tail of the second bolt 73. The second connecting plate 72 and the other outer frame strip 11 of frame 1 are connected by passing the second bolt 73 through the second connecting plate 72 and then fitting the second nut 74 onto the tail of the second bolt 73. This completes the connection setup of the connector 7.

[0121] Of course, the connection of connector 7 can also be achieved by welding.

[0122] With the above configuration, at the corner where the end of the inner frame strip 2 connects to the frame 1, the connector 7 can be connected to both the frame 1 and the inner frame strip 2, thereby increasing the structural strength at the corner where the end of the inner frame strip 2 connects to the frame 1. And / or, the connector 7 can be connected to the two outer frame strips 11 of the frame 1 at the corner, thereby increasing the structural strength at the corner of the frame 1.

[0123] The above are merely preferred embodiments of this disclosure and do not limit the patent scope of this disclosure. Any equivalent structural or procedural transformations made using the content of this disclosure and its drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this disclosure.
