Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a door end cover assembly, a door assembly and a refrigeration equipment. BACKGROUND

[0002] At present, in the related art, the door body of a refrigerator generally comprises an end cover structure and a foaming layer, and the foaming layer is connected with the end cover structure. The end cover structure is generally a plastic part, and the foaming layer is generally polyurethane. The thermal expansion coefficient of the foaming layer is much higher than that of the end cover structure connected therewith. When the temperature changes, the expansion or contraction of the foaming layer is easy to cause the deformation of the end cover structure, thereby causing the warping deformation of the door body of the refrigerator. When the warping deformation further increases, it will cause the door seal to be detached, the leakage of cold air, the condensation and other problems. CONTENT OF THE UTILITY MODEL

[0003] The present application aims to at least solve the technical problem in the related art that the foaming layer is connected with the end cover structure in the door body of a refrigerator, and due to the difference in thermal expansion coefficients between the two, the expansion or contraction of the foaming layer is easy to cause the deformation of the end cover structure when the temperature changes, thereby causing the warping deformation of the door body of the refrigerator.

[0004] To this end, the present application provides a door end cover assembly in a first aspect.

[0005] A door assembly is provided in a second aspect of the present application.

[0006] A refrigeration equipment is provided in a third aspect of the present application.

[0007] Therefore, the present application provides a door end cover assembly, which is used in a door assembly. The door assembly comprises a door body and a foaming layer. The door end cover assembly comprises: a first end cover arranged at one end of the door body; a second end cover arranged at the other end of the door body, and the first end cover and the second end cover are wrapped around the edges of the end portions of the door body; a first reinforcing plate arranged on the first end cover and located between the first end cover and the foaming layer, and extending along the length direction of the first end cover; and a second reinforcing plate arranged on the second end cover and located between the second end cover and the foaming layer, and extending along the length direction of the second end cover. The first reinforcing plate and the second reinforcing plate are PC plates, and the cross section of the first reinforcing plate or the second reinforcing plate is E-shaped in the cross section perpendicular to the length direction of the first end cover or the second end cover.

[0008] The door end cover assembly provided by the present application comprises a first end cover, a second end cover, a first reinforcing plate and a second reinforcing plate. The first end cover is arranged at one end of the door body, and the second end cover is arranged at the other end of the door body. The first end cover and the second end cover are wrapped around the edges of the end portions of the door body. That is, the first end cover and the second end cover are respectively mounted on the upper side and the lower side of the door body to realize the surrounding and edge wrapping of the door body, so that the door body and the first end cover and the second end cover are wrapped into a complete face plate of the door assembly.

[0009] The first reinforcing plate is arranged on the first end cover and located between the first end cover and the foaming layer and extends along the length direction of the first end cover. That is, the first reinforcing plate is arranged between the first end cover and the foaming layer to separate the first end cover and the foaming layer and avoid contact between the first end cover and the foaming layer. By extending the first reinforcing plate along the length direction of the first end cover, the length of the first reinforcing plate is lengthened, and the contact area between the first end cover and the foaming layer is further reduced. Similarly, the second reinforcing plate is arranged on the second end cover and located between the second end cover and the foaming layer and extends along the length direction of the second end cover. In this way, by arranging the second reinforcing plate between the second end cover and the foaming layer, the second end cover and the foaming layer are separated, and contact between the second end cover and the foaming layer is avoided. By extending the second reinforcing plate along the length direction of the second end cover, the length of the second reinforcing plate is lengthened, and the contact area between the second end cover and the foaming layer is further reduced.

[0010] Specifically, the first reinforcing plate and the second reinforcing plate are PC plates, and a cross section of the first reinforcing plate or the second reinforcing plate perpendicular to the length direction of the first end cover or the second end cover is in an E shape. By arranging the first reinforcing plate and the second reinforcing plate as PC plates and arranging the first reinforcing plate and the second reinforcing plate between the door body end cover assembly and the foaming layer, the contact area between the foaming layer and the door body end cover assembly is blocked, the deformation of the door body end cover assembly caused by the expansion or contraction of the foaming layer is reduced, and the problem that the door body is easily deformed due to the expansion or contraction of the foaming layer is effectively solved. At the same time, by arranging the cross section of the first reinforcing plate or the second reinforcing plate in an E shape, the moment of inertia of the cross section of the first reinforcing plate or the second reinforcing plate is effectively improved, and the deformation resistance is improved. That is, by arranging the cross section of the first reinforcing plate or the second reinforcing plate in an E shape, effective support is provided for the first end cover and the second end cover, the contact between the first end cover and the second end cover and the foaming layer is effectively blocked, and the probability of deformation of the door body end cover assembly caused by the expansion or contraction of the foaming layer is reduced.

[0013] In the technical solution, the first end cover comprises a first end cover body. One side of the first end cover body is provided with a first bent flange, a first bent groove is formed between the first bent flange and the first end cover body, and the first reinforcing plate is arranged in the first bent groove. In this way, the first end cover body and the first bent flange can be effectively supported by the first reinforcing plate, preventing structural instability caused by external force or material deformation. In addition, the first end cover and the foaming layer can be physically isolated by the first reinforcing plate. This isolation not only reduces the direct contact area between the two and reduces the risk of deformation caused by the difference in material thermal expansion coefficient, but also ensures the stability and durability of the door end cover assembly during long-term use.

One side of the second end cover body is provided with a second bent flange, a second bent groove is formed between the second bent flange and the second end cover body, and the second reinforcing plate is arranged in the second bent groove. The advantage of this layout is that the second reinforcing plate can effectively support the second end cover body and the second bent flange, preventing structural instability caused by external force or material deformation.

The clamping groove is arranged on the second reinforcing plate and corresponds to the clamping jaw, that is, one clamping jaw corresponds to one clamping groove. This design not only simplifies the installation process, but also improves the stability and reliability of the connection. In this way, in the case of installation of the second reinforcing plate and the second end cover, the clamping jaw can easily enter the clamping groove and be clamped on the clamping groove, thereby realizing firm connection between the two.

[0020] In some technical schemes, optionally, the number of buckle parts is multiple, and the multiple buckle parts are uniformly distributed along the length direction of the second end cover.

[0021] In the technical scheme, in order to improve the stability and uniformity of the connection between the second end cover and the second reinforcing plate, the number of buckle parts is set to multiple, and the buckle parts are uniformly distributed along the length direction of the second end cover.

[0055] One embodiment of the present application provides a door end cap assembly 100 for a door assembly 200, the door assembly 200 comprising a door body 210 and a foamed layer 220, the door end cap assembly 100 comprising: a first end cap 110 arranged at one end of the door body 210; a second end cap 120 arranged at the other end of the door body 210, and the first end cap 110 and the second end cap 120 being wrapped around the edges of the end portions of the door body 210; a first reinforcing plate 160 arranged on the first end cap 110, between the first end cap 110 and the foamed layer 220, and extending along the length direction of the first end cap 110; and a second reinforcing plate 170 arranged on the second end cap 120, between the second end cap 120 and the foamed layer 220, and extending along the length direction of the second end cap 120; wherein the first reinforcing plate 160 and the second reinforcing plate 170 are PC plates, and along the length direction perpendicular to the first end cap 110 or the second end cap 120, the cross section of the first reinforcing plate 160 or the second reinforcing plate 170 is E-shaped.

[0056] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 9 , the door end cap assembly 100 comprises the first end cap 110, the second end cap 120, the first reinforcing plate 160 and the second reinforcing plate 170. The first end cap 110 is arranged at one end of the door body 210, and the second end cap 120 is arranged at the other end of the door body 210, and the first end cap 110 and the second end cap 120 are wrapped around the edges of the end portions of the door body 210. That is, the first end cap 110 and the second end cap 120 are respectively mounted on the upper side and the lower side of the door body 210, so as to realize the surrounding and edge covering of the door body 210, so that the door body 210 and the first end cap 110 and the second end cap 120 are surrounded to form a complete face plate of the door assembly 200.

[0057] Specifically, as shown in Figure 3 and Figure 6As shown, the length direction of the first end cover 110 is X, the length direction of the second end cover 120 is Y, the first reinforcing plate 160 is arranged on the first end cover 110 and located between the first end cover 110 and the foaming layer 220, and extends along the length direction of the first end cover 110. That is, the first reinforcing plate 160 is mounted between the first end cover 110 and the foaming layer 220 to separate the first end cover 110 and the foaming layer 220, avoid the contact between the first end cover 110 and the foaming layer 220, and lengthen the first reinforcing plate 160 by extending the first reinforcing plate 160 along the length direction of the first end cover 110, so as to further reduce the contact area between the first end cover 110 and the foaming layer 220. Similarly, the second reinforcing plate 170 is mounted on the second end cover 120 and located between the second end cover 120 and the foaming layer 220, and extends along the length direction of the second end cover 120. In this way, the second reinforcing plate 170 is mounted between the second end cover 120 and the foaming layer 220 to separate the second end cover 120 and the foaming layer 220, avoid the contact between the second end cover 120 and the foaming layer 220, and lengthen the second reinforcing plate 170 by extending the second reinforcing plate 170 along the length direction of the second end cover 120, so as to further reduce the contact area between the second end cover 120 and the foaming layer 220.

[0058] Specifically, the first reinforcing plate 160 and the second reinforcing plate 170 are PC plates, and the cross section of the first reinforcing plate 160 or the second reinforcing plate 170 is E-shaped in the direction perpendicular to the length direction of the first end cover 110 or the second end cover 120. By setting the first reinforcing plate 160 and the second reinforcing plate 170 as PC plates, and arranging the first reinforcing plate 160 and the second reinforcing plate 170 between the door body end cover assembly 100 and the foaming layer 220, the contact area between the foaming layer 220 and the door body end cover assembly 100 can be blocked, and the deformation of the door body end cover assembly 100 caused by the expansion or contraction of the foaming layer 220 can be reduced, effectively solving the problem that the deformation of the door body end cover assembly 100 caused by the expansion or contraction of the foaming layer 220 easily leads to the warping deformation of the door body 210. At the same time, by setting the cross section of the first reinforcing plate 160 or the second reinforcing plate 170 as E-shaped, the moment of inertia of the cross section of the first reinforcing plate 160 or the second reinforcing plate 170 can be effectively improved, and the anti-deformation ability can be improved. That is, by setting the cross section of the first reinforcing plate 160 or the second reinforcing plate 170 as E-shaped, the first end cover 110 and the second end cover 120 can be effectively supported, and the contact between the first end cover 110 and the second end cover 120 and the foaming layer 220 can be effectively blocked, and the probability of the deformation of the door body end cover assembly 100 caused by the expansion or contraction of the foaming layer 220 can be reduced.

[0059] Specifically, at present, in the relevant technology, the refrigerator door body usually includes an end cover structure and a foam layer, and the foam layer is connected to the end cover structure. The end cover structure is generally a plastic part, and the foam layer is generally polyurethane. The thermal expansion coefficient of the foam layer is much higher than that of the end cover structure connected to it. When the temperature changes, the expansion or contraction of the foam layer can easily cause the end cover structure to deform, thereby causing the refrigerator door body to warp and deform. When the warping deformation increases further, it will cause problems such as door seal debonding, cold leakage, and condensation.

[0060] This application addresses this issue. Figure 1 and Figure 2 As shown, a door end cap assembly 100 is proposed, comprising a first end cap 110 and a second end cap 120. The first end cap 110, i.e., an upper end cap, is disposed on the upper side of the door body 210, and the second end cap 120, i.e., a lower end cap, is disposed on the lower side of the door body 210. The door body 210 is enclosed and covered by the upper and lower end caps to form a complete panel of the door body 210. Furthermore, by disposing a first reinforcing plate 160 between the first end cap 110 and the foam layer 220, and a second reinforcing plate 170 between the second end cap 120 and the foam layer 220, contact between the first and second end caps 110, 120, and the foam layer 220 is blocked. In this way, when the temperature changes, the expansion or contraction of the foam layer 220 is not likely to cause deformation of the door end cap assembly 100, nor will it cause warping and deformation of the door assembly 200 of the refrigeration equipment 300, such as a refrigerator.

[0061] Specifically, the first reinforcing plate 160 and the second reinforcing plate 170 are both PC boards, and the PC board, that is, a polycarbonate board (PC), serves as a reinforcing plate supporting the first end cover 110 and the second end cover 120, as well as a partition used to block the contact between the door end cover assembly 100 and the foam layer 220. The PC board not only has high strength, high transparency and good weather resistance, but more importantly, its thermal expansion coefficient is relatively close to that of the foam layer 220. This feature minimizes the thermal expansion difference between the PC board and the foam layer 220 when the temperature changes, thereby effectively reducing the deformation problem caused by thermal expansion and contraction. Compared with other materials, this feature of the PC board enables the door end cover assembly 100 to exhibit higher stability and durability when responding to environmental changes. In addition, the PC board has a lightweight feature. While ensuring strength, the lightweight design helps to reduce the weight of the entire door assembly 200.

[0062] In addition, if Figure 4 and Figure 5 As shown, and Figure 10 and Figure 11As shown, the cross sections of the first and second reinforcing plates 160 and 170 are designed in an E shape, which not only increases their cross-sectional moments of inertia, but also significantly enhances their deformation resistance. The E-shaped cross section increases the distribution area of the material, enabling the structure to better disperse stress when subjected to external forces, thereby improving the overall load-carrying capacity and stability. This allows it to withstand larger bending moments or torques, such as in the door end cap assembly 100, effectively resisting the pressure generated by the expansion or contraction of the foamed layer 220, preventing the door end cap assembly 100 from deforming. Moreover, the E-shaped cross section is not simply an increase in the thickness or width of the material, but rather a design that achieves the goal of improving structural strength while maintaining lightweight. The E-shaped cross sections of the first and second reinforcing plates 160 and 170 can be achieved through precise mold forming processes during manufacturing, which can improve production efficiency and reduce manufacturing costs.

[0063] In some embodiments, as shown in Figure 3 and Figure 4 The first end cap 110 includes a first end cap body 112, one side of which is provided with a first bent flange 114, and a first bent groove 116 is formed between the first bent flange 114 and the first end cap body 112. The first reinforcing plate 160 is arranged in the first bent groove 116 to support the first end cap body 112 and the first bent flange 114 through the first reinforcing plate 160, and to isolate the first end cap 110 and the foamed layer 220 through the first reinforcing plate 160.

[0064] Specifically, as shown in Figure 4 The first end cap 110 includes a first end cap body 112. One side of the first end cap body 112 is provided with a first bent flange 114, and a first bent groove 116 is formed between the first bent flange 114 and the first end cap body 112. The first reinforcing plate 160 is arranged in the first bent groove 116, which not only effectively supports the first end cap body 112 and the first bent flange 114 through the first reinforcing plate 160, preventing structural instability due to external forces or material deformation, but also physically isolates the first end cap 110 from the foamed layer 220 through the first reinforcing plate 160. This isolation not only reduces the direct contact area between the two, reducing the risk of deformation caused by differences in material thermal expansion coefficients, but also ensures the stability and durability of the door end cap assembly 100 during long-term use.

[0065] Specifically, since the first reinforcing plate 160 is embedded into the first bending groove 116, during the installation process, the position and angle of the first reinforcing plate 160 can be more easily controlled, ensuring a close fit between the first reinforcing plate 160 and the first end cover body 112 and the first bending flange 114. This not only improves installation efficiency, but also reduces the risk of performance degradation or damage due to improper installation, thereby enhancing the structural strength of the first end cover 110. With such a spatial layout, an ideal position is provided for the installation of the first reinforcing plate 160. Thus, by providing the first end cover 110 with the first bending flange 114 and the first bending groove 116, and embedding the first reinforcing plate 160 therein, not only the structural strength and stability of the door end cover assembly 100 are improved, but also the risk of deformation due to differences in material thermal expansion coefficients is reduced.

[0066] In some embodiments, as shown in Figure 6 、 Figure 7 、 Figure 9 and Figure 10 , the second end cover 120 includes a second end cover body 122. One side of the second end cover body 122 is provided with a second bending flange 124, and a second bending groove 126 is formed between the second bending flange 124 and the second end cover body 122. A second reinforcing plate 170 is arranged in the second bending groove 126 to support the second end cover body 122 and the second bending flange 124 through the second reinforcing plate 170, and to isolate the second end cover 120 and the foaming layer 220 through the second reinforcing plate 170.

[0067] Specifically, as shown in Figure 7 and Figure 10 , the second end cover 120 includes a second end cover body 122. One side of the second end cover body 122 is provided with a second bending flange 124, and a second bending groove 126 is formed between the second bending flange 124 and the second end cover body 122. A second reinforcing plate 170 is arranged in the second bending groove 126 to support the second end cover body 122 and the second bending flange 124 through the second reinforcing plate 170, and to isolate the second end cover 120 and the foaming layer 220 through the second reinforcing plate 170.

[0068] Specifically, the second end cover 120 is similar in design to the first end cover 110. Since the second reinforcing plate 170 is embedded in the second bending groove 126, the position and angle of the reinforcing plate can be more easily controlled during installation, ensuring a tight fit between the second reinforcing plate 170 and the second end cover body 122 and the second bending flange 124. This not only improves installation efficiency, but also reduces the risk of performance degradation or damage due to improper installation. Moreover, the fit between the second reinforcing plate 170 and the second bending groove 126 has additional stability. For example, when the door end cover assembly 100 is subjected to external forces, the second reinforcing plate 170 can effectively disperse stress and transmit it to the second end cover body 122 and the second bending flange 124, thereby improving the anti-deformation ability of the entire assembly. Therefore, by providing the second bending flange 124 and the second bending groove 126 on the second end cover 120 and embedding the second reinforcing plate 170 in the second bending groove 126, not only the structural strength and stability of the door end cover assembly 100 are improved, but also the risk of deformation due to differences in material thermal expansion coefficients is reduced.

[0069] In some embodiments, as shown in Figures 3 to 10 , the first end cover 110 is fixedly connected to the first reinforcing plate 160 by adhesive bonding, and the second end cover 120 further comprises a buckle portion 130, and the second reinforcing plate 170 is fixedly connected to the second end cover 120 by the buckle portion 130.

[0070] Specifically, as shown in Figure 3 and Figure 6 , the first end cover 110 and the first reinforcing plate 160 are connected by adhesive bonding. This connection method is simple and easy to implement, and can effectively ensure a tight fit between the two, while avoiding stress concentration problems that may be caused by mechanical connections. Adhesive bonding not only provides stable support, but also reduces the risk of performance degradation due to loose connections. As for the connection between the second end cover 120 and the second reinforcing plate 170, a buckle portion 130 is designed, and the second end cover 120 is connected to the second reinforcing plate 170 by the buckle portion 130, i.e. through a buckle connection to achieve a firm connection between the two. This buckle connection method is not only easy to install, but also can resist external impact and vibration to some extent, ensuring the stability and reliability of the door end cover assembly 100 during long-term use.

[0071] Specifically, when the first end cover 110 is fixedly connected with the first reinforcing plate 160, an adhesive with high strength and good weather resistance is usually selected. Such an adhesive can not only ensure the close fit between the two, but also maintain stable performance in extreme environments. The buckle portion 130 can be made of an elastic material and has a certain deformation capacity and recovery. During the clamping process, the buckle portion 130 can be moderately deformed and clamped with the second reinforcing plate 170, thereby achieving firm locking of the second reinforcing plate 170. This not only improves the stability and reliability of the connection, but also can absorb and disperse external force impact to a certain extent, protecting the door body end cover assembly 100 from damage. In addition, the buckle portion 130 is also designed for easy disassembly. When the second reinforcing plate 170 needs to be disassembled or replaced, the buckle portion 130 can be easily released by simple operation, achieving quick disassembly.

[0072] In some embodiments, as shown in Figure 6 、 Figure 7 and Figure 8 , the buckle portion 130 includes a clamping jaw 132 provided on the end face of the second end cover body 122 and extending along the direction perpendicular to the end face of the second end cover body 122, and a clamping groove 134 provided on the second reinforcing plate 170 and corresponding to the clamping jaw 132. When the second reinforcing plate 170 and the second end cover 120 are installed, the clamping jaw 132 is provided in the clamping groove 134 and clamped on the clamping groove 134.

[0073] Specifically, as shown in Figure 6 and Figure 8 , the buckle portion 130 includes a clamping jaw 132 and a clamping groove 134. The clamping jaw 132 is provided on the end face of the second end cover body 122 and extends along the direction perpendicular to the end face of the second end cover body 122, i.e. the clamping jaw 132 extends in the thickness direction of the second end cover body 122. The clamping groove 134 is provided on the second reinforcing plate 170 and corresponds to the clamping jaw 132, i.e. one clamping jaw 132 corresponds to one clamping groove 134. This design not only simplifies the installation process, but also improves the stability and reliability of the connection. In this way, when the second reinforcing plate 170 and the second end cover 120 are installed, the clamping jaw 132 can easily enter the clamping groove 134 and be clamped on the clamping groove 134, thereby achieving firm connection between the two.

[0074] Specifically, the clamping jaw 132 can be made of an elastic material, and has a certain deformation capacity and recovery. During clamping, the clamping jaw 132 can be moderately deformed to pass into the clamping groove 134, and quickly recover to the original state after clamping, thereby achieving firm locking of the second reinforcing plate 170. In this way, not only the stability and reliability of the connection are improved, but also external force impact can be absorbed and dispersed to a certain extent, protecting the door body end cover assembly 100 from damage. By adopting the design of the clamping buckle part 130 combining the clamping jaw 132 and the clamping groove 134, not only the installation process is simplified, but also the stability and reliability of the connection are improved.

[0075] In some embodiments, as shown in Figure 6 , the number of clamping buckle parts 130 is multiple, and the multiple clamping buckle parts 130 are uniformly distributed along the length direction of the second end cover 120.

[0076] Specifically, as shown in Figure 6 , in order to improve the stability and uniformity of the connection between the second end cover 120 and the second reinforcing plate 170, the number of clamping buckle parts 130 is set to multiple, and the clamping buckle parts 130 are uniformly distributed along the length direction of the second end cover 120. In this way, not only the strength and durability of the connection are enhanced, but also the uniformity and stability of the connection are ensured, avoiding the problem of connection failure caused by excessive local stress.

[0077] Specifically, as shown in Figure 6 , the length direction of the second end cover 120 is Y, and the uniform distribution of the multiple clamping buckle parts 130 can ensure that the second reinforcing plate 170 is more firmly fixed on the second end cover 120. Each clamping buckle part 130 bears a certain connection force, and when subjected to external force, these forces will be uniformly dispersed to each clamping buckle part 130, thereby reducing the stress load of a single clamping buckle part 130 and improving the overall connection strength. In addition, since the clamping buckle parts 130 are uniformly distributed in the length direction, the multiple clamping buckle parts 130 can cooperate together to prevent the second reinforcing plate 170 from shifting or deforming in the length direction Y of the second end cover 120. By adopting the uniform distribution of the multiple clamping buckle parts 130 along the length direction Y of the second end cover 120, not only the stability and uniformity of the connection between the second end cover 120 and the second reinforcing plate 170 are improved, but also the overall connection strength and durability are enhanced.

[0078] In some embodiments, as shown in Figure 6 and Figure 7 , the second end cover 120 further includes a positioning part 140, and the number of the positioning part 140 is two. The two positioning parts 140 are arranged along the length direction of the second end cover 120 to position the second reinforcing plate 170 during installation of the second reinforcing plate 170.

[0079] Specifically, as shown in Figure 6 and Figure 7 To further improve the installation accuracy and stability of the second reinforcing plate 170 on the second end cover 120, the second end cover 120 further comprises a positioning portion 140. The number of the positioning portion 140 is two, and it is distributed along the length direction of the second end cover 120, that is, in the length direction of the second end cover 120, the positioning portion 140 is arranged at both ends of the second end cover 120. In this way, not only is it helpful to accurately position the second reinforcing plate 170 during installation, but also ensures the stability and reliability after installation.

[0080] Specifically, the positioning portion 140 serves to provide a clear installation reference for the second reinforcing plate 170. During installation, the operator can easily place the second reinforcing plate 170 to the correct position according to the position and shape of the positioning portion 140, avoiding the risk of performance degradation or damage due to inaccurate installation position. At the same time, the design of the positioning portion 140 also takes into account the convenience and efficiency of installation. Since the positioning portion 140 is distributed along the length direction of the second end cover 120, the operator can easily slide or push the second reinforcing plate 170 along this direction until it is completely aligned and fitted with the positioning portion 140. This design not only simplifies the installation process, but also improves the installation efficiency.

[0081] In addition, the positioning portion 140 can also cooperate with the buckle portion 130 to jointly ensure the firm connection of the second reinforcing plate 170 on the second end cover 120. During installation, the positioning portion 140 first provides a preliminary positioning for the second reinforcing plate 170, and then the buckle portion 130 further locks the second reinforcing plate 170 on the second end cover 120 through the cooperation of the clamping jaw 132 and the clamping groove 134, further improving the stability and reliability of the connection.

[0082] In some embodiments, optionally, as shown in Figure 6 and Figure 7 The positioning portion 140 comprises a positioning sheet 142 arranged on the end face of the second end cover body 122 and extending along a direction perpendicular to the end face of the second end cover body 122, and a positioning groove 144 arranged on the second reinforcing plate 170 and corresponding to the positioning sheet 142, wherein the positioning sheet 142 is clamped in the positioning groove 144 when the second reinforcing plate 170 is installed on the second end cover 120.

[0083] Specifically, as shown in Figure 7As shown, the positioning part 140 includes a positioning sheet 142 and a positioning groove 144. The positioning sheet 142 is arranged on the end face of the second end cover body 122 and extends along the direction perpendicular to the end face of the second end cover body 122, that is, the positioning sheet 142 is arranged protruding on the second end cover body 122, or it can be understood that the positioning sheet 142 is arranged protruding in the thickness direction of the second end cover body 122. The positioning groove 144 is arranged on the second reinforcing plate 170 and corresponds to the positioning sheet 142, so that when the second reinforcing plate 170 is installed with the second end cover 120, the positioning sheet 142 can be clamped in the positioning groove 144, realizing the positioning of the second reinforcing plate 170. In this way, not only the accurate installation of the second reinforcing plate 170 on the second end cover 120 is ensured, but also the convenience and stability of installation are improved.

[0084] Specifically, the positioning sheet 142 is a protruding part arranged on the end face of the second end cover body 122 and extending along the direction perpendicular to the end face of the second end cover body 122. This design enables the positioning sheet 142 to closely cooperate with the positioning groove 144 on the second reinforcing plate 170 during installation, thereby realizing the accurate positioning of the second reinforcing plate 170. The shape and size of the positioning sheet 142 are determined according to the actual size and shape of the second reinforcing plate 170, so as to ensure the close fit and firm connection between them. The positioning groove 144 is a groove structure arranged on the second reinforcing plate 170 and corresponding to the positioning sheet 142. The shape and size of the positioning groove 144 are matched with those of the positioning sheet 142, so as to ensure that the positioning sheet 142 can be smoothly clamped into the positioning groove 144 during installation. In this way, not only the installation process is simplified, but also the accuracy and stability of installation are improved.

[0085] In addition, the cooperation of the positioning sheet 142 and the positioning groove 144 not only ensures the accuracy of installation, but also improves the stability of connection. Since the positioning sheet 142 extends along the direction perpendicular to the end face of the second end cover body 122, it can effectively prevent the movement of the second reinforcing plate 170 in the vertical direction.

[0086] In some embodiments, optionally, as shown in Figure 9 and Figure 10 As shown, the second end cover 120 further includes a fixing part 150 arranged on the second end cover body 122 and located at both ends of the second end cover body 122 in the length direction of the second end cover 120, so as to fix the second reinforcing plate 170 in the length direction of the second end cover 120.

[0087] Specifically, as shown in Figure 10As shown, the second end cover 120 further comprises a fixing portion 150. The fixing portion 150 is arranged on the second end cover body 122 and located at both ends of the second end cover body 122 in the length direction of the second end cover 120. It can be understood that the fixing portion 150 is arranged in the width direction of the second end cover body 122, which can prevent the second reinforcing plate 170 from moving in the length direction of the second end cover 120 and enhance the fixing effect of the second reinforcing plate 170 on the second end cover 120. Such arrangement not only helps to additionally fix the second reinforcing plate 170 in the length direction of the second end cover 120, but also improves the stability and reliability of the overall structure.

[0088] Specifically, the fixing portion 150 serves to provide an additional fixing point for the second reinforcing plate 170 to increase its stability in the length direction of the second end cover 120. During installation, the operator can first place the second reinforcing plate 170 on the second end cover 120 and preliminarily position and fix it through the positioning portion 140 and the buckle portion 130. Then, the second reinforcing plate 170 is further fixed by the fixing portion 150 to ensure its firmness in the length direction of the second end cover 120.

[0089] Specifically, the fixing portion 150 can be specifically arranged as a buckle boss which has a certain deformation ability and recovery. During the fixing of the second reinforcing plate 170, the buckle boss can be moderately deformed to buckle and fix the second reinforcing plate 170, achieving firm locking of the second reinforcing plate 170. Such arrangement not only improves the stability and reliability of the fixing, but also can absorb and disperse external force impact to a certain extent, protecting the door body end cover assembly 100 from damage. At the same time, such design also provides convenience for subsequent maintenance and replacement, reducing maintenance cost and time cost.
