[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] like Figure 1 and Figure 2 As shown, some embodiments of the present invention provide a fixed plate structure, which is mainly used in magnetic sheet tracks to improve the production efficiency and production quality of the fixed plate structure.

[0039] The fixed plate structure includes a plurality of plate bodies 100. It should be noted that the number of the plate bodies 100 can be two or more than two, and can be specifically set according to actual conditions.

[0040] Along the thickness direction of the plate body 100, a plurality of plate bodies 100 are stacked in sequence to form the fixed plate structure. Specifically, in this embodiment, a plurality of plate bodies 100 are pressed together by in-mold riveting technology to form the fixed plate structure.

[0041] It is worth noting that the in-mold riveting technology is a technology that uses a punching machine and a special connection mold to connect two or more layers of plates of different materials and thicknesses through an instantaneous high-pressure processing process. This technology forms a stress-free internal inlaid dot with a certain tensile and shear strength based on the cold extrusion deformation of the plate material itself, thereby achieving connection. The application of in-mold riveting technology not only improves production efficiency, but also saves riveting equipment, reduces the process of pre-punching and riveting of the wire body, and thus reduces costs. In addition, the implementation of in-mold riveting technology depends on specific tools and processes, including in-mold punching and riveting tools and hydraulic forming equipment. The design of these tools and equipment makes it possible to punch and rivet simultaneously inside the mold, further improving production efficiency. Specifically, the in-mold punching and riveting tool includes a first mold and a second mold that are relatively set, as well as components such as a feeding punch and a riveting punch. These components work together under the control of the control system to realize the process of punching and riveting directly inside the mold without transferring the formed parts, thereby simplifying the production process.

[0042] Specifically, the plate body 100 has a first wall surface 110 and a second wall surface 120 disposed opposite to each other, the first wall surface 110 is parallel to the second wall surface 120, and along the thickness direction of the plate body 100, the first wall surface 110 and the second wall surface 120 overlap, and a plurality of plate bodies 100 overlap each other.

[0043] In addition, a portion of the first wall 110 is arched toward a side away from the second wall 120 to form a plurality of spaced-apart bosses 130, and an installation channel 200 is defined between two adjacent bosses 130. The installation channel 200 extends along the width direction of the plate body 100, that is, the extension direction of the installation channel 200 is parallel to the width direction of the plate body 100. The installation channel 200 is used to install a magnetic sheet to form a magnetic sheet track on the plate body 100.

[0044] It should be noted that a part of the second wall surface 120 is recessed toward one side of the first wall surface 110 to form a plurality of spaced grooves 140. It should be noted that in one plate body 100, the number of the grooves 140 is equal to the number of the bosses 130, and one groove 140 corresponds to one boss 130, that is, along the thickness direction of the plate body 100, the projection of one boss 130 on the first wall surface 110 coincides with the projection of one groove 140 on the first wall surface 110, so that two adjacent plate bodies 100 can be tightly stacked.

[0045] It should be noted that, along the thickness direction of the plate body 100, the distance between the second wall 120 and the bottom of the groove 140 is equal to the distance between the first wall 110 and the side of the boss 130 facing away from the first wall 110, so that in two adjacent plate bodies 100, one of the bosses 130 of one of the plate bodies 100 can be completely accommodated in one of the grooves 140 of the other plate body 100.

[0046] Among them, some of the plate bodies 100 among the multiple plate bodies 100 are provided with through holes 150. It can be understood that at least one of the multiple plate bodies 100 is not provided with a through hole 150. The through hole 150 penetrates the plate body 100 along the thickness direction of the plate body 100 to form a blind hole 160 on one side of the thickness direction of the fixed plate structure, so as to facilitate the installation of the wire in the blind hole 160, so that the blind hole 160 can protect, limit and fix the wire, thereby ensuring the stability of the wire in the blind hole 160.

[0047] It is worth noting that the through hole 150 is disposed at the edge of the board body 100 . In the present embodiment, the through hole 150 is disposed at the top corner of the board body 100 .

[0048] It is difficult to drill the blind hole 160 directly on the fixed plate structure, mainly because the chips are difficult to discharge and the machining accuracy is high, which will cause the chips to accumulate in the chip groove, which may cause burrs to form on the hole wall, affecting the molding quality.

[0049] Based on this, the present application can avoid setting blind holes 160 on the plate body 100 by setting through holes 150 on a part of the multiple plate bodies 100, thereby reducing the difficulty of drilling and avoiding burrs on the hole wall. By connecting multiple plate bodies 100 through riveting to form a fixed plate structure, not only can the production process of the magnetic sheet assembly be simplified, but also the production efficiency of the fixed plate structure can be improved, and the production cost of the fixed plate structure can be reduced.

[0050] By controlling the number of the plates 100 , the thickness of the magnetic sheet assembly can be adjusted, thereby improving the diversity and utilization rate of the magnetic sheet assembly, thereby meeting different needs of users.

[0051] In addition, it can be understood that by controlling the number of plates 100 with through holes 150 to adjust the depth of the blind hole 160, the user's requirements for different depths of the blind hole 160 can be met, so as to further enhance the flexibility of the magnetic sheet assembly during installation or production and improve the utilization rate of the magnetic sheet assembly.

[0052] It should be noted that the blind hole 160 refers to a hole on the board body 100 , which connects the surface layer and the inner layer of the board body 100 but does not penetrate the board body 100 .

[0053] like Figure 2 As shown, in some embodiments of the present invention, there are multiple through holes 150, and the multiple through holes 150 are located on the same side of the thickness direction of the magnetic sheet assembly, and the multiple through holes 150 are connected in sequence to form the blind hole 160 on one side of the thickness direction of the fixed plate structure.

[0054] It should be noted that, in this embodiment, the plurality of through holes 150 means that when a plurality of plates 100 are provided with through holes 150 , at this time, the number of the through holes 150 is plural.

[0055] Specifically, the number of the through holes 150 is less than the number of the plate body 100 , so that the plurality of through holes 150 can be connected to form a blind hole 160 on one side of the fixed plate structure in the thickness direction.

[0056] Exemplarily, the plurality of plates 100 include at least one first plate and at least one second plate, wherein the first plate is provided with a through hole 150 or the second plate is provided with a through hole 150, and the first plate and the second plate are stacked in sequence along the thickness direction of the plate 100 to form a magnetic sheet assembly.

[0057] like Figure 1 As shown, in some embodiments of the utility model, in two adjacent plate bodies 100, the second wall surface 120 of one of the plate bodies 100 is attached to the first wall surface 110 of the other plate body 100, and the boss 130 of one of the plate bodies 100 is completely accommodated in the groove 140 of the other plate body 100, so that the boss 130 is guided and limited by the groove 140, which can not only improve the efficiency of the connection between the two adjacent plate bodies 100, but also improve the tightness of the connection between multiple plate bodies 100.

[0058] like Figures 2 to 4 As shown, in some embodiments of the present invention, the plurality of bosses 130 are arranged at equal intervals along the length direction of the plate body 100, and the length direction of the bosses 130 is parallel to the width direction of the plate body 100, so that a plurality of spaced-apart mounting channels 200 are defined on one side of the thickness direction of the plate body 100 by the plurality of bosses 130.

[0059] It should be noted that the multiple bosses 130 are parallel to each other, so that the axes of each mounting channel 200 are parallel to each other, that is, the multiple mounting channels 200 are arranged at equal intervals along the length direction of the plate body 100, to ensure that a magnetic piece can be installed in each mounting channel 200, and the magnetic pieces installed on the plate body 100 are arranged at equal intervals along the length direction of the plate body 100.

[0060] like Figure 1 and Figure 2As shown, in some embodiments of the present invention, along the thickness direction of the plate body 100, the projection of the boss 130 on the first wall surface 110 coincides with the projection of the groove 140 on the first wall surface 110, that is, the number of grooves 140 and bosses 130 on a plate body 100 is equal, and each groove 140 corresponds to a boss 130.

[0061] It is understandable that when two adjacent plates 100 are stacked on each other, the boss 130 of one plate 100 can be completely accommodated in the groove 140 of the other plate 100, thereby achieving the function of connecting multiple plate bodies 100 to each other, that is, the user can set the number of plate bodies 100 according to actual needs.

[0062] In addition, by allowing the boss 130 to be correspondingly accommodated in the groove 140, the groove 140 can guide and limit the boss 130 to ensure the accuracy of the installation position between two adjacent plates 100, improve the installation efficiency between two adjacent plates 100, and thus improve the production efficiency of the magnetic sheet assembly.

[0063] like Figures 1 to 5 As shown, in some embodiments of the present invention, along the width direction of the plate body 100 , the length of the boss 130 is smaller than the width of the plate body 100 .

[0064] like Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the boss 130 includes a first supporting foot 131, a connecting plate 132 and a second supporting foot 133, and the first supporting foot 131 and the second supporting foot 133 are respectively arranged at both ends of the length direction of the connecting plate 132 to form a trapezoidal structure boss 130.

[0065] In addition, in this embodiment, the groove 140 is a trapezoidal groove, so that the two inclined groove walls of the trapezoidal groove can provide a guiding function for the boss 130, thereby improving the accuracy and efficiency of the connection or installation between two adjacent plates 100.

[0066] There is a gap between the connecting plate 132 and the plate body 100 to form a clearance space between the boss 130 and the plate body 100, which can not only reduce the weight of the plate body 100 but also reduce the production cost of the magnetic sheet assembly.

[0067] In some embodiments of the present invention, the angle between the first supporting leg 131 and the connecting plate 132 is α, wherein 90°<α≤150°.

[0068] It can be understood that the value range of α includes any range of 90°<α≤150°, 95°≤α≤150°, 100°≤α≤150°, 105°≤α≤150°, 110°≤α≤150°, 115°≤α≤150°, 120°≤α≤150°, 125°≤α≤150°, 130°≤α≤150°, 135°≤α≤150°, 140°≤α≤150°, and 145°≤α≤150°, and can be set according to actual conditions.

[0069] The included angle between the second supporting leg 133 and the connecting plate 132 is β, wherein 90°<β≤150°. In addition, α and β satisfy the relationship α=β.

[0070] It can be understood that the first supporting foot 131 and the second supporting foot 133 are symmetrically arranged at both ends of the connecting plate 132 in the length direction, so that along the thickness direction of the plate body 100, the side of the boss 130 away from the second wall 120 is completely overlapped with the side of the boss 130 facing the second wall 120, thereby ensuring that when two adjacent plate bodies 100 are connected, the boss 130 of one plate body 100 can be completely fitted with the groove 140 of the other plate body 100, thereby ensuring the tightness of the connection between the two plate bodies 100 and improving the production accuracy and quality of the magnetic sheet assembly.

[0071] like Figures 1 to 5 As shown, in some embodiments of the present invention, a plurality of spaced apart positioning holes 170 are provided at the edge of the plate body 100 , and the positioning holes 170 penetrate the plate body 100 along the thickness direction of the plate body 100 .

[0072] The number of the positioning holes 170 may be two or more than two, and may be set according to actual conditions.

[0073] It should be noted that, along the width direction of the plate body 100 , the plurality of positioning holes 170 are respectively disposed at both ends of the plate body 100 .

[0074] Specifically, along the width direction of the plate body 100 , the number of the positioning holes 170 disposed on both sides of the plate body 100 is equal, and the plurality of positioning holes 170 on the plate body 100 are arranged at equal intervals along the length direction of the plate body 100 .

[0075] Some embodiments of the utility model provide a magnetic sheet track, including a magnetic sheet and the fixed plate structure, wherein the magnetic sheet is arranged in the installation channel 200, and the side wall of the magnetic sheet is connected to the channel wall of the installation channel 200, so as to form a limiting and fixing effect on the magnetic sheet through two adjacent bosses 130, so as to ensure the stability of the magnetic sheet in the installation channel 200.

[0076] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0077] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
