An operating table

Abstract

This application provides an operating table. The operating table includes a tabletop, a column assembly, and a protective cover assembly. The column assembly is used to drive the tabletop to rise and fall. The protective cover assembly surrounds the outer periphery of the column assembly and includes multiple protective covers that are stacked sequentially and can move relative to each other along the height direction. Each protective cover is formed by splicing a first half-cover and a second half-cover in a first direction, and the protective cover includes a cover body. In two adjacent protective covers, the first half-cover of the outer protective cover includes a first bent portion extending inward from the outer protective cover body, and the second half-cover of the inner protective cover includes a second bent portion extending outward from the inner protective cover body. The first bent portion extends along the first direction between the inner protective cover body and the second bent portion of the inner protective cover, so as to achieve anti-detachment cooperation between the adjacent protective covers in the inward and outward directions. The operating table provided by this application has a relatively simple anti-detachment structure between the protective covers and a low cost.

Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an operating table. Background Technology

[0002] In related technologies, during the raising and lowering of the operating table, the column guards move up and down along with the table surface, protecting the internal structure. The stability of the structure and the smoothness of the raising and lowering are crucial for adjusting the height of the operating table. Anti-detachment structures are installed between each layer of guards to prevent excessive relative movement in the horizontal direction and to prevent the two layers of guards from separating. Current products have relatively complex and costly anti-detachment structures. Summary of the Invention

[0003] In view of this, the present application aims to provide an operating table with a simple and low-cost anti-detachment structure between the protective covers.

[0004] This application provides an embodiment of an operating bed, including:

[0005] mesa;

[0006] The column assembly located below the tabletop is used to drive the tabletop to rise and fall.

[0007] A protective cover assembly surrounds the outer periphery of the column assembly. The protective cover assembly includes multiple protective covers that are nested in sequence and can move relative to each other along the height direction.

[0008] Each of the shields is formed by splicing a first half-shield and a second half-shield in a first direction, and the shield includes a shield body;

[0009] In the two adjacent protective layers, the first half of the outer protective layer includes a first bent portion extending inward from the outer protective layer body, and the second half of the inner protective layer includes a second bent portion extending outward from the inner protective layer body. The first bent portion extends along a first direction to the space between the inner protective layer body and the second bent portion of the inner protective layer, so as to achieve anti-detachment cooperation between the two adjacent protective layers in the inward and outward directions.

[0010] In some embodiments, within the relative movement range of two adjacent protective layers, the orthographic projections of the first bending portion and the second bending portion in the inward and outward directions always have overlapping areas.

[0011] In some embodiments, the first bend of the outer protective cover does not overlap with the projection of the outer protective cover body in the inward and outward directions, and the second bend of the inner protective cover overlaps with the projection of the inner protective cover body in the inward and outward directions; or,

[0012] The first bend of the outer protective cover overlaps with the projection of the outer protective cover body in the inward and outward directions, while the second bend of the inner protective cover does not overlap with the projection of the inner protective cover body in the inward and outward directions.

[0013] In some embodiments, within the relative movement range of two adjacent protective layers, the first bending portion of the outer protective layer and the orthographic projection of the inner protective layer body in the inward and outward directions always have an overlapping area; the second bending portion of the inner protective layer and the orthographic projection of the outer protective layer body in the inward and outward directions always have an overlapping area.

[0014] In some embodiments, the first half-cover is a one-piece structure; and / or, the second half-cover is a one-piece structure.

[0015] In some embodiments, the first half-cover is a one-piece sheet metal part; and / or, the second half-cover is a one-piece sheet metal part.

[0016] In some embodiments, the first bend extends in the height direction, and the extension length of the first bend is not less than the relative movement stroke of the two adjacent protective layers.

[0017] In some embodiments, the second bending portion is disposed on the upper part of the inner protective cover, and within the relative movement range of two adjacent protective covers, both the first bending portion and the second bending portion are hidden inside the body of the outer protective cover.

[0018] In some embodiments, the second bend does not overlap with the orthographic projection of the inner protective cover body in the inward and outward directions.

[0019] In some embodiments, the first half of the outer protective cover is bent inward at least one end where it is joined with the second half to form the first bent portion; and / or, the second half of the inner protective cover is bent outward a portion of the top edge of at least one end where it is joined with the first half to form the second bent portion.

[0020] In some embodiments, the second bend extends in the height direction, and the extension length of the second bend is not less than the relative movement stroke of the two adjacent protective layers.

[0021] In some embodiments, the first bend is located at the lower part of the outer shield, and the second bend is exposed on the outside of the outer shield body, at least when two adjacent shields move to their extreme positions in a direction away from each other.

[0022] In some embodiments, the first bend does not overlap with the orthographic projection of the outer protective cover body in the inward and outward directions.

[0023] In some embodiments, the second half of the inner protective cover is bent outward at least one end of the inner half of the outer protective cover to form the second bent portion, and a portion of the bottom edge of the first half of the outer protective cover is bent inward at least one end of the outer half of the outer protective cover to form the first bent portion.

[0024] The operating table provided in this application embodiment has a first bend and a second bend between adjacent protective covers. The structure of the first bend, the second bend, the inner protective cover body, and the outer protective cover body achieves anti-detachment cooperation in the inward and outward directions. This structure is simple and reliable, easy to assemble, and can reduce manufacturing costs. In addition, the first bend and the outer protective cover body can be formed integrally without relative movement between them, and the second bend and the inner protective cover body can be formed integrally without relative movement between them. The structure has high reliability and is not prone to jamming during the relative movement of the inner and outer protective covers along the height direction of the operating table.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0037] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover 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. Unless otherwise specified, 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. "A plurality of" means two or more.

[0038] This application provides an operating table for supporting a medical patient during surgery. Please refer to [link / reference]. Figure 1 The operating table includes a tabletop, a column assembly 20, and a protective cover assembly 30.

[0039] The operating table supports the patient via its surface.

[0040] The column assembly 20 is disposed below the tabletop and provides support for the tabletop. Exemplarily, in one embodiment, the operating table includes a base 40, which is placed on the ground, and the bottom end of the column assembly 20 is connected to the base 40. In another embodiment, the bottom end of the column assembly 20 is supported and fixed to the ground; that is, in this embodiment, the base 40 can be omitted.

[0041] The column assembly 20 is used to drive the table to rise and fall. Exemplarily, the column assembly 20 includes a lifting column 21 connected to the table. That is, the height of the lifting column 21 is adjustable; by adjusting the position of the lifting column 21, the height of the table can be changed, facilitating surgery. Exemplarily, the column assembly 20 also includes a support column (not shown), the bottom end of which is connected to a base 40, allowing the lifting column 21 to rise and fall relative to the support column.

[0042] The protective cover assembly 30 surrounds the outer perimeter of the column assembly 20. The protective cover assembly 30 constitutes the exterior component of the operating table, separating the external environment, such as the operating room, from the column assembly 20. On the one hand, the protective cover assembly 30 protects the column assembly 20 and the pipelines extending from the column assembly 20 to the table surface, preventing other components from scratching or impacting the column assembly 20; on the other hand, it serves an aesthetic purpose.

[0043] Please see Figure 3 and Figure 4 The protective cover assembly 30 includes multiple protective covers, which are stacked sequentially and can move relative to each other along the height direction D3, thereby following the rise and fall of the column assembly 20 through this relative movement.

[0044] Each protective cover is formed by splicing a first half-cover and a second half-cover in the first direction D1. That is, the first half-cover and the second half-cover are two independent parts that are spliced ​​together to form the protective cover. For example, the first half-cover and the second half-cover are riveted, screwed, glued, welded, etc.

[0045] The first direction D1 is generally horizontal; for example, the first direction D1 can be the head-to-toe direction or the left-right direction of the operating table. For example, the first half-cover is located to the left of the second half-cover, or the first half-cover is located to the right of the second half-cover.

[0046] It should be noted that the first and second halves of the same protective shield can be the same or different, and no restrictions are imposed here.

[0047] The protective shield includes the shield body. The shield body is the main structure of the protective shield.

[0048] It should be noted that the naming of the shield body, the first half-shield, and the second half-shield represents a structural division of the shield from different perspectives. For example, a portion of the first half-shield and a portion of the second half-shield are joined together in the first direction D1 to form the shield body.

[0049] Please see Figure 2 , Figure 4 and Figure 5 In the two adjacent protective layers, the first half of the outer protective layer 31 (denoted as 310A) includes a first bent portion 301 extending inward from the outer protective layer body (denoted as 310), and the second half of the inner protective layer 32 (denoted as 320B) includes a second bent portion 302 extending outward from the inner protective layer body (denoted as 320). For example, in the orthographic projection of a plane perpendicular to the height of the operating table, the orthographic projections of the first bent portion 301 and the second bent portion 302 are both located between the orthographic projections of the outer protective layer body 310 and the inner protective layer body 320. The first bent portion 301 can bend inward first and then extend in a direction parallel to the outer protective layer body 310. The second bent portion 302 can bend outward first and then extend in a direction parallel to the inner protective layer body 320.

[0050] The first bend 301 extends along the first direction D1 to the space between the inner protective cover body 320 and the second bend 302 of the inner protective cover 32, thereby achieving anti-detachment engagement between the two adjacent protective covers in the inward and outward directions. That is, the first bend 301 is confined in the space between the inner protective cover body 320 and the second bend 302 in the inward and outward directions, limiting the displacement of the outer protective cover 31 and the inner protective cover 32 in the inward and outward directions, making it difficult for the two adjacent protective covers to detach from each other in the inward and outward directions. The aforementioned inward and outward directions are perpendicular to the height direction D3.

[0051] It should be noted that the first bending portion 301 extends along the first direction D1 to the space between the inner protective cover body 320 and the second bending portion 302 of the inner protective cover 32. This can be understood as follows: a gap region is formed between the inner protective cover body 320 and the second bending portion 302 of the inner protective cover 32. An opening is formed between the end of the second bending portion 302 in the first direction D1 and the inner protective cover body 320. The opening is connected to the gap region, and the opening is located on the side of the gap region in the first direction D1 closer to the first half cover. The first bending portion 301 passes through the opening and extends into the aforementioned gap region.

[0052] It should be noted that when projected onto the same plane along the inner and outer directions, the projection areas of the second bend 302 of the inner protective cover 32 and the projection area of ​​the inner protective cover body 320 may overlap or not overlap.

[0053] It should be noted that the "protective cover body" refers to the remaining parts of a single protective cover, excluding the first bend 301 and / or the second bend 302. Specifically, when the same protective cover has both a first bend 301 and a second bend 302, then the remaining parts of the protective cover, excluding the first bend 301 and the second bend 302, are collectively referred to as the protective cover body. When a protective cover has a first bend 301 but no second bend 302, then the remaining parts of the protective cover, excluding the first bend 301, are collectively referred to as the protective cover body. When a protective cover has a second bend 302 but no first bend 301, then the remaining parts of the protective cover, excluding the second bend 302, are collectively referred to as the protective cover body.

[0054] The operating table of this application embodiment has a first bending portion 301 and a second bending portion 302 formed between adjacent protective covers. The structure of the first bending portion 301, the second bending portion 302, the inner protective cover body 320, and the outer protective cover body 310 achieves anti-detachment engagement in the inward and outward directions. This structure is simple and reliable, easy to assemble, and can reduce manufacturing costs. In addition, the first bending portion 301 and the outer protective cover body 310 can be formed integrally without relative movement between them, and the second bending portion 302 and the inner protective cover body 320 can be formed integrally without relative movement between them. The structure has high reliability and is not prone to jamming during the relative movement of the inner protective cover 32 and the outer protective cover 31 along the height direction of the operating table.

[0055] The number of shields can be two, three, or more. For example, in an embodiment with two shields, the outer shield 31 is the outermost shield as described above, the inner shield 32 is the innermost shield, and there is no intermediate shield. When the number of shields is three or more, in addition to the outermost shield and the innermost shield, there is at least one intermediate shield.

[0056] It should be noted that the inner and outer protective layers mentioned above refer only to their relative positions in the inward and outward directions. For example, please refer to... Figure 2 and Figure 4Regarding the outermost protective layer, as indicated by F1, the outermost protective layer can only serve as the aforementioned outer protective layer 31, and cannot serve as the inner protective layer 32. Therefore, the outermost protective layer can only have the first bending portion 301, and not the second bending portion 302. Regarding the innermost protective layer, as indicated by F5, the innermost protective layer can only serve as the aforementioned inner protective layer 32, and cannot serve as the outer protective layer 31. Therefore, the innermost protective layer can only have the second bending portion 302, and not the first bending portion 301. Regarding the intermediate protective layer between the outermost and innermost protective layers, as indicated by F2, F3, and F4, the same intermediate protective layer serves as both the inner protective layer 32 and the outer protective layer 31. That is, the same intermediate protective layer has both the second bending portion 302 and the first bending portion 301. Specifically, for the same intermediate layer shield and an adjacent shield located on its outer side (which can be the outermost shield or another intermediate layer shield), the intermediate layer shield is used as the inner shield 32, and the adjacent shield on the outer side is used as the outer shield 31; while for the same intermediate layer shield and an adjacent shield located on its inner side (which can be the innermost shield or another intermediate layer shield), the intermediate layer shield is used as the outer shield 31, and the adjacent shield on the inner side is used as the inner shield 32.

[0057] For example, in one embodiment, please refer to Figure 6 The first half-cover, along the second direction D2, includes a first bending portion 301 at both ends, i.e., the ends where it joins with the second half-cover. The second half-cover, along the second direction D2, also includes a second bending portion 302 at both ends, i.e., the ends where it joins with the second half-cover. The first direction D1, the second direction D2, and the height direction D3 are perpendicular to each other. Adjacent protective covers are secured at both joints between the first and second half-covers to prevent detachment, resulting in more stable relative movement between the covers.

[0058] For example, in one embodiment, please refer to Figure 5 In addition to the innermost protective cover, the first half of the same protective cover also includes a transition section 303. The transition section 303 connects the first bending section 301 and the main body of the protective cover. The transition section 303 bends inward from the edge of the first half of the protective cover. A portion of the second half of the same protective cover overlaps the outer surface of the transition section 303, making the outer surfaces of the second half of the protective cover flush with those of the first half, thus improving the aesthetics of the protective cover. It is understood that the portion of the second half of the protective cover forming the main body of the protective cover partially overlaps the transition section of the first half of the protective cover. This portion of the protective cover body can be joined together using fasteners 50 such as screws or rivets. The location of the seam between the first and second half of the protective cover can be referenced in the attached diagram. Figure 5 A diagram illustrating the dashed line 'm'.

[0059] In some embodiments, the first half-cover is a one-piece structure. One-piece structures are easy to manufacture, have only one component, high structural strength, and can eliminate assembly steps. For example, the first half-cover is a one-piece plastic part, and the first bent portion 301 can be processed by injection molding; or, the first half-cover is a one-piece sheet metal part, and the first bent portion 301 can be processed by bending or stamping. Sheet metal parts have high structural strength, and the structure of the first bent portion 301 is more reliable.

[0060] In some embodiments, the second half-cover is a one-piece structure. One-piece structures are easy to manufacture, have only one component, high structural strength, and can eliminate assembly steps. For example, the second half-cover is a one-piece plastic part, and the second bending portion 302 can be manufactured using injection molding; or, the second half-cover is a one-piece sheet metal part, and the second bending portion 302 can be manufactured using bending or stamping processes. Sheet metal parts have high structural strength, and the structure of the second bending portion 302 is more reliable.

[0061] In some embodiments, please refer to Figure 2 and Figure 6 Within the relative movement range of two adjacent protective layers, the orthographic projections of the first bend 301 of the outer protective layer and the second bend 302 of the inner protective layer in the inward and outward directions always overlap. That is, when the two adjacent protective layers move relative to each other, and the first bend 301 and second bend 302 of the outer protective layer move accordingly, in the inward and outward directions, the first bend 301 of the outer protective layer is at least partially always located within the space between the inner protective layer body 320 and the second bend 302. This allows the second bend 302 to achieve full-stroke anti-detachment cooperation between the two adjacent protective layers in the inward and outward directions, making the relative movement between the protective layers more stable and improving the reliability of the operating table.

[0062] It should be noted that the first bend 301 of the outer protective cover is at least partially located within the space between the inner protective cover body 320 and the second bend 302. This means that at least a portion of the first bend 301 overlaps with the projection of the inner protective cover body 320, and / or at least a portion of the first bend 301 overlaps with the projection of the second bend 302. However, this does not mean that the projections of the inner protective cover body 320 and the second bend 302 must necessarily overlap when projected orthographically onto the same plane in the inward and outward directions.

[0063] For example, the first bend 301 of the outer protective cover does not overlap with the projection of the outer protective cover body in the inward and outward directions, while the second bend 302 of the inner protective cover overlaps with the projection of the inner protective cover body in the inward and outward directions. For example, please refer to... Figure 7The first half-cover 310A has a notch formed at the first bend 301, and the first bend 301 is located at the notch, so that the projections of the first bend 301 and the outer cover body in the inward and outward directions do not overlap. The second bend 302 on the second half-cover 320B of the inner cover extends to the outside of the first half-cover 320A of the inner cover, and the projections of the second bend 302 and the first half-cover 320A in the inward and outward directions overlap.

[0064] Alternatively, the first bend 301 of the outer protective layer overlaps with the projection of the outer protective layer body in the inward and outward directions, while the second bend 302 of the inner protective layer does not overlap with the projection of the inner protective layer body in the inward and outward directions. For example, please refer to... Figure 2 and Figure 3 The first bend 301 on the first half-cover 310A of the outer protective cover is located inside the second half-cover of the outer protective cover, and the projections of the first bend 301 and the second half-cover of the outer protective cover overlap in the inward and outward directions. The second half-cover 320B of the inner protective cover forms a notch at the location of the second bend 302, and the second bend 302 is located at the notch, so that the projections of the second bend 302 and the inner protective cover body do not overlap in the inward and outward directions.

[0065] In some embodiments, within the relative movement range of two adjacent protective layers, the first bending portion 301 of the outer protective layer and the orthographic projection of the inner protective layer body in the inward and outward directions always overlap; the second bending portion 302 of the inner protective layer and the orthographic projection of the outer protective layer body in the inward and outward directions always overlap. Thus, the relative movement between two adjacent protective layers is smoother.

[0066] The following is a brief description of two embodiments of the protective cover assembly 30 with reference to the accompanying drawings.

[0067] First Embodiment

[0068] Please refer to the structure of the first embodiment. Figures 2 to 5The first bend 301 of the outer protective cover 31 extends in the height direction D3, and the extension length of the first bend 301 is not less than the relative movement stroke of the two adjacent protective covers. "Not less than" in this specification includes both "greater than" and "equal to". In this embodiment, the first bend 301 has a guiding function along the height direction D3, and the relative movement direction of the first bend 301 and the second bend 302 is along the extension direction of the first bend 301, making it less prone to jamming and resulting in smoother movement. Furthermore, the extension length of the second bend 302 along the height direction D3 can be smaller, and the mating length with the first bend 301 is also smaller, which can reduce processing accuracy requirements, reduce frictional resistance, and improve smoothness. Furthermore, when two adjacent protective covers move relative to each other in the height direction, a portion of the outer protective cover 31 is located above the inner protective cover 32, and the first bending portion 301 is located inside the outer protective cover body 310, making it less likely to be exposed to the outside of the protective cover assembly 30. This helps to maintain the flatness of the appearance of the outer protective cover body 310 and improves the aesthetics of the protective cover assembly 30.

[0069] In a partial embodiment where the extension length of the first bend 301 is not less than the relative travel distance between the two adjacent protective layers, please refer to... Figure 2 and Figure 5 The second bending portion 302 is disposed on the upper part of the inner protective cover 32. Within the relative movement range of the two adjacent protective covers, both the first bending portion 301 and the second bending portion 302 are hidden inside the outer protective cover body 310. That is, the first bending portion 301 and the second bending portion 302 do not protrude from the outer protective cover body 310 along the height direction D3. In this way, when the first bending portion 301 and the second bending portion 302 move relative to each other, they are not easily exposed to the outside of the protective cover assembly 30, which can improve the aesthetics of the protective cover assembly 30.

[0070] Understandably, in this embodiment, as the two adjacent protective layers move away from each other to their extreme positions, the second bend 302 moves downward relative to the first bend 301, meaning the outer protective layer 31 rises relative to the inner protective layer 32. The second bend 302's placement on the upper part of the inner protective layer 32 helps to shorten the overlap length along the height direction D3 between the two adjacent protective layers, resulting in a more compact structure.

[0071] In some embodiments, please refer to Figure 3 The second bend 302 and the inner protective cover body 320 do not overlap in the inward and outward directions when projected onto each other. That is to say, the second bend 302 is extended from the inner protective cover body 320 by the second half-cover, and the inner protective cover body 320 avoids the second bend 302 at the corresponding positions in the inward and outward directions. This structure has simpler requirements for the blank and is easier to process and manufacture.

[0072] For example, in an embodiment where the second half-cover is a one-piece sheet metal part, the second bent portion 302 can be obtained by cutting or stamping on the basis of the blank.

[0073] In some embodiments, please refer to Figure 2 The first half-cover 310A of the outer protective cover 31, at least one end of which is used to splice with the second half-cover 310B, is bent inward to form a first bent portion 301. That is, the first half-cover 310A of the outer protective cover 31, at each location along the height direction D3, has a first bent portion 301. There can be multiple first bent portions 301, spaced apart from each other along the height direction D3. This results in a relatively long extension length of the first bent portions 301 along the height direction D3, which can meet the requirements of the relative movement range between adjacent protective covers. Alternatively, in some embodiments, the two ends of the first half-cover 310A of the outer protective cover 31, which are used to splice with the second half-cover 310B, are bent inward to form the first bent portion 301, such that the length of the first bent portion 301 along the height direction D3 is equal to the height of the first half-cover 310A.

[0074] In some embodiments, please refer to Figure 3 and Figure 5 The second half-cover 320B of the inner protective cover 32, at least one end of which is used to splice with the first half-cover 320A, has a portion of its top edge bent outward to form a second bent portion 302. That is, only a portion of the top edge of the end of the second half-cover 320B of the inner protective cover 32 used to splice with the first half-cover 320A has the second bent portion 302. Thus, the extension length of the second bent portion 302 along the height direction D3 is small, making it less likely to affect the connection between the second half-cover 320B and the first half-cover 320A, and also less likely to affect the structural strength of the second half-cover 320B. Of course, in some embodiments, portions of the top edges of both ends of the second half-cover 320B of the inner protective cover 32 used to splice with the first half-cover 320A may be bent outward to form the second bent portion 302.

[0075] It should be noted that the aforementioned bending does not specifically refer to a bending process, but rather to a structure that is bent. This bending can be achieved through injection molding or cold forming processes.

[0076] It should be noted that, for ease of understanding, Figure 5 The dark shaded area schematically represents the structure of the second half-cover 320B of the inner protective cover 32, and the light shaded area schematically represents the structure of the second half-cover 310B of the outer protective cover 31.

[0077] Second Embodiment

[0078] Please refer to the structure of the second embodiment. Figure 6 and Figure 7 .

[0079] The second bend 302 extends in the height direction D3, and the extension length of the second bend 302 is not less than the relative movement stroke of the two adjacent protective layers. In this embodiment, the second bend 302 has a guiding function along the height direction D3. The relative movement direction of the first bend 301 and the second bend 302 is along the extension direction of the second bend 302, making it less prone to jamming and resulting in smoother movement. In addition, the extension length of the first bend 301 along the height direction D3 can be smaller to save material, and the mating length with the second bend 302 is also smaller, which can reduce the processing accuracy requirements.

[0080] Of course, in other embodiments, the first bending portion 301 and the second bending portion 302 may both extend in the height direction D3, and their extension lengths are equal and not less than the relative movement stroke of the two adjacent protective layers.

[0081] In a partial embodiment where the extension length of the second bend 302 is not less than the relative travel distance between the two adjacent protective layers, please refer to... Figure 6 and Figure 7 The first bend 301 is located at the lower part of the outer protective cover 31, and the second bend 302 is exposed on the outside of the outer protective cover body 310, at least when the two adjacent protective covers move to their extreme positions in the direction of moving away from each other. This facilitates assembly.

[0082] It is understood that in this embodiment, during the process of the two adjacent protective layers moving away from each other to their extreme positions, the first bending portion 301 moves upward relative to the second bending portion 302, that is, the outer protective layer 31 rises relative to the inner protective layer 32. The first bending portion 301 is located at the lower part of the outer protective layer 31, which helps to shorten the length of overlap between the two adjacent protective layers along the height direction D3, resulting in a more compact structure.

[0083] In some embodiments, please refer to Figure 4 and Figure 5 The first bend 301 and the outer cover body 310 do not overlap in the inward and outward directions when projected onto each other. That is to say, the first bend 301 is extended from the outer cover body 310 by the first half cover, and the outer cover body 310 avoids the first bend 301 at the corresponding positions in the inward and outward directions. This structure has simpler requirements for the blank and is easier to process and manufacture.

[0084] For example, in an embodiment where the first half-cover is an integral sheet metal part, the first bent portion 301 can be obtained by cutting or stamping on the basis of the blank.

[0085] In some embodiments, please refer to Figure 6The second half-cover 320B of the inner protective cover 32 is bent outward at least one end to form a second bent portion 302. This results in a longer extension length of the second bent portion 302 along the height direction D3, which can meet the relative movement range requirements of adjacent protective covers. Alternatively, in some embodiments, the second half-cover 320B of the inner protective cover 32 may be bent inward at both ends to form the second bent portion 302.

[0086] In some embodiments, a portion of the bottom edge of the first half-cover 310A of the outer protective cover 31, at least one end of which is used to splice with the second half-cover 310B, is bent inward to form a first bent portion 301. That is, only a portion of the bottom edge of the first half-cover 310A of the outer protective cover 31, at the end used to splice with the second half-cover 310B, forms the first bent portion 301. Thus, the extension length of the first bent portion 301 along the height direction D3 is small, making it less likely to affect the connection between the first half-cover 310A and the second half-cover 310B, and also less likely to affect the structural strength of the first half-cover 310A. Of course, in some embodiments, portions of the bottom edges of both ends of the first half-cover 310A of the outer protective cover 31, which are used to splice with the second half-cover 310B, are bent inward to form the first bent portion 301.
