[0023] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0024] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0025] The split splicing structure 100 according to the first aspect embodiment of the present utility model will be described below with reference to the drawings.

[0026] As Figures 1 - 5As shown in the figure, the split splicing structure 100 according to the embodiment of the first aspect of the present invention includes: a first split member 1, a second split member 2, and a limit pin. The first split member 1 includes a connected first main body portion 13 and a first splicing portion 11. A first limit structure 111, a second limit structure 112, and a first pin hole are formed on the first splicing portion 11. The first split member 1 and the second split member 2 are independently formed. The second split member 2 includes a connected second main body portion 22 and a second splicing portion 21. A third limit structure 211, a fourth limit structure 212, and a second pin hole are formed on the second splicing portion 21. The third limit structure 211 and the fourth limit structure 212 are respectively connected to the first limit structure 111 and the second limit structure 112. The second pin hole is opposite to the first pin hole. The limit pin is inserted into the first pin hole and the second pin hole.

[0027] Among them, since the first split member 1 and the second split member 2 are independently formed, the processing and forming difficulty of the first split member 1 and the second split member 2 can be reduced. For example, when the structure of the split splicing structure 100 is relatively complex or the size is relatively large, by dividing the split splicing structure 100 into multiple parts that can be independently formed, the structure of each split component such as the first split member 1 and the second split member 2 is relatively simple, and at the same time the size is smaller, which is convenient for the forming of each split component, so as to meet the requirements of the complex shape of the split splicing structure 100, and at the same time improve the processing and forming efficiency of the split splicing structure 100.

[0028] In addition, through the connection between the first limit structure 111 and the third limit structure 211, the connection between the second limit structure 112 and the fourth limit structure 212, and the cooperation between the limit pin and the first pin hole and the second pin hole, the connection between the first splicing portion 11 and the second splicing portion 21 can be realized, so that the first split member 1 and the second split member 2 are connected into an integral structure through the connection between the first splicing portion 11 and the second splicing portion 21. And, through the connection between the first limit structure 111 and the third limit structure 211, a first connection position can be formed between the first splicing portion 11 and the second splicing portion 21. Through the connection between the second limit structure 112 and the fourth limit structure 212, a second connection position can be formed between the first splicing portion 11 and the second splicing portion 21. Through the insertion of the limit pin into the first pin hole and the second pin hole, a third connection position can be formed between the first splicing portion 11 and the second splicing portion 21. That is, there are at least three connection positions in the connection area between the first split member 1 and the second split member 2, so as to realize the multi-lock connection between the first split member 1 and the second split member 2.

[0029] Thus, by connecting the first limiting structure 111 with the third limiting structure 211, connecting the second limiting structure 112 with the fourth limiting structure 212, and matching the limiting pin with the first pin hole and the second pin hole, the connection positions in the connection area between the first split part 1 and the second split part 2 can be increased, thereby enhancing the strength of the splicing position between the first split part 1 and the second split part 2, and further enhancing the overall structural strength of the split splicing structure 100.

[0030] For the split splicing structure 100 according to the first aspect embodiment of the present invention, by connecting the first limiting structure 111 with the third limiting structure 211, connecting the second limiting structure 112 with the fourth limiting structure 212, and matching the limiting pin with the first pin hole and the second pin hole, the connection positions in the connection area between the first split part 1 and the second split part 2 can be increased, thereby enhancing the strength of the splicing position between the first split part 1 and the second split part 2, and further enhancing the overall structural strength of the split splicing structure 100.

[0031] Among them, the limiting pin can be in interference fit with the first pin hole and the second pin hole. Specifically, the diameter of the part of the limiting pin passing through the first pin hole is greater than the inner diameter of the first pin hole, and the diameter of the part of the limiting pin passing through the second pin hole is greater than the inner diameter of the second pin hole, so as to prevent the limiting pin from disengaging from the first pin hole and the second pin hole. In addition, the connection strength between the limiting pin and the first pin hole and the second pin hole can be further increased by gluing. For example, glue can be applied to the outer peripheral surface of the limiting pin and / or the inner peripheral surfaces of the first pin hole and the second pin hole to achieve gluing.

[0032] According to some embodiments of the present invention, the first limiting structure 111 is in snap-fit with the third limiting structure 211, and the second limiting structure 112 is in snap-fit with the fourth limiting structure 212. Among them, the snap-fit has the advantages of simple structure, easy installation and high connection strength. Therefore, the matching difficulty between the first limiting structure 111 and the third limiting structure 211, and the matching difficulty between the second limiting structure 112 and the fourth limiting structure 212 can be reduced, thereby reducing the connection difficulty between the first splicing part 11 and the second splicing part 21, and improving the splicing efficiency of the first split part 1 and the second split part 2.

[0033] According to some embodiments of the present utility model, the first splicing portion 11 further includes a first connecting portion 113. The first connecting portion 113 has a first side surface 1131 and a second side surface 1132 that are arranged at an angle and connected along a first direction e1. A splicing space 1133 is defined between the first side surface 1131 and the second side surface 1132. The second splicing portion 21 further includes a second connecting portion 213. The second connecting portion 213 is located in the splicing space 1133 and is spaced apart from the first side surface 1131 along a second direction e2. The first limiting structure 111 and the second limiting structure 112 are arranged along the first direction e1 on the first connecting portion 113, and the third limiting structure 211 and the fourth limiting structure 212 are arranged along the first direction e1 on the second connecting portion 213. That is to say, the first connection position and the second connection position between the first splicing portion 11 and the second splicing portion 21 are arranged along the first direction e1. Thus, the connection positions between the first splicing portion 11 and the second splicing portion 21 in the first direction e1 can be preferably increased, so that the connection strength between the first splicing portion 11 and the second splicing portion 21 in the first direction e1 can be improved. At the same time, the first connection position and the second connection position can make full use of the space in the first direction e1, thereby saving the space occupied by the first splicing portion 11 and the second splicing portion 21 in the second direction e2, where the second direction e2 is perpendicular to the first direction e1. As Figure 1 shown, the second direction e2 is the thickness direction of the first main body portion 13. By reducing the space occupied by the first splicing portion 11 and the second splicing portion 21 in the second direction e2, interference between the first splicing portion 11 and the second splicing portion 21 and the components located inside the first main body portion 13 and the second main body portion 22 can be avoided.

[0034] According to some embodiments of the present utility model, the side surface of the second connecting portion 213 facing the first side surface 1131 in the second direction e2 is a third side surface 2131. The first limiting structure 111 and the third limiting structure 211 are respectively arranged on the first side surface 1131 and the third side surface 2131 and are both formed as hooks. The first limiting structure 111 and the first side surface 1131 define a first groove 114 that opens away from the second side surface 1132. A second groove 214 that opens towards the second side surface 1132 is defined between the third limiting structure 211 and the third side surface 2131. The free ends of the first limiting structure 111 and the third limiting structure 211 are respectively located in the second groove 214 and the first groove 114. The second limiting structure 112 and the fourth limiting structure 212 are respectively arranged on the first connecting portion 113 and the second connecting portion 213 and are both formed as elastic buckles. The second limiting structure 112 and the fourth limiting structure 212 are clamped and matched along the first direction e1, and the free end of the second limiting structure 112 is located on the side of the free end of the fourth limiting structure 212 facing the third side surface 2131. Wherein, the second direction e2 is perpendicular to the first direction e1.

[0035] That is to say, at least part of the first connecting portion 113 and at least part of the second connecting portion 213 are opposite and spaced apart along the second direction e2, and the first limiting structure 111 and the third limiting structure 211 are located in the region where the first connecting portion 113 and the second connecting portion 213 are opposite in the second direction e2. Wherein, the free end of the first limiting structure 111 refers to the end of the first limiting structure 111 extending in the direction away from the first side surface 1131, the free end of the second limiting structure 112 refers to the end of the second limiting structure 112 extending in the direction away from the first connecting portion 113, the free end of the third limiting structure 211 refers to the end of the third limiting structure 211 extending in the direction away from the third side surface 2131, and the free end of the fourth connecting structure refers to the end of the fourth limiting structure 212 extending in the direction away from the second connecting portion 213.

[0036] It can be understood that both the first limiting structure 111 and the third limiting structure 211 are in the shape of a hook, and the free end of the first limiting structure 111 is bent in the direction away from the first main body portion 13, and the free end of the third limiting structure 211 is bent in the direction close to the first main body portion 13. That is, the bending directions of the first limiting structure 111 and the second limiting structure 112 are opposite, so that the free ends of the first limiting structure 111 and the third limiting structure 211 can be buckled along the first direction e1. Thus, through the cooperation of the first limiting structure 111 and the third limiting structure 211, the degree of freedom of relative movement of the first sub-component 1 and the second sub-component 2 in the second direction e2 can be better restricted. At the same time, the blocking of the first limiting structure by the third limiting structure 211 can prevent the first main body portion 13 from moving in the direction close to the second main body portion 22.

[0037] In addition, through the blocking of the second limiting structure 112 by the fourth limiting structure 212, the first main body portion 13 can be better prevented from moving in the direction away from the second main body portion 22. Thus, under the cooperation of the first limiting structure 111 and the third limiting structure 211 and the cooperation of the second limiting structure 112 and the fourth limiting structure 212, the degree of freedom of relative movement of the first sub-component 1 and the second sub-component 2 in the first direction e1 can be restricted. Therefore, through the cooperation of the first limiting structure 111 and the third limiting structure 211 and the cooperation of the second limiting structure 112 and the fourth limiting structure 212, the degree of freedom of relative movement of the first sub-component 1 and the second sub-component 2 in the first direction e1 and the second direction e2 can be restricted to improve the connection strength between the first sub-component 1 and the second sub-component 2.

[0038] Secondly, through the cooperation of the limit pin with the first pin hole and the second pin hole, the degrees of freedom of relative movement of the first split part 1 and the second split part 2 in the third direction (not shown in the figure) can be restricted, where the third direction is perpendicular to the first direction e1 and perpendicular to the second direction e2. Thus, six-directional limitation between the first split part 1 and the second split part 2 can be achieved to ensure the firm splicing of the first split part 1 and the second split part 2. Specifically, the first pin hole can penetrate the first connecting portion 113 along the thickness direction of the first connecting portion 113, and the extending direction of the second pin hole is the same as that of the first pin hole. Therefore, after the limit pin is inserted into the first pin hole and the second pin hole, through the connection between the limit pin and the first connecting portion 113 and the second connecting portion 213, relative movement in the third direction between the first splicing portion 11 and the second splicing portion 21 can be prevented, thereby restricting the relative movement of the first split part 1 and the second split part 2 in the third direction.

[0039] According to some embodiments of the present invention, at least a support block 2132 that abuts against the third side surface 2131 is further formed on the third side surface 2131. The support block 2132 is located on the side of the first limiting structure 111 and the third limiting structure 211 facing the second side surface 1132. That is to say, the second side surface 1132 abuts against the support block 2132 along the first direction e1. Thus, through the cooperation between the second side surface 1132 and the support block 2132, the movement of the first split part 1 and the second split part 2 in the direction of approaching each other along the first direction e1 can be preferably prevented, thereby further improving the stability of the relative position of the first split part 1 and the second split part 2 in the first direction e1. In addition, through the support block 2132, at least part of the gap between the first connecting portion 113 and the second connecting portion 213 can be preferably filled, facilitating the subsequent adhesive bonding process. In a specific example, the first side surface 1131 can be arranged parallel to the third side surface 2131, which can save the space occupied by the first splicing portion 11 and the second splicing portion 21 in the second direction e2. In addition, the angle between the second side surface 1132 and the first side surface 1131 is an obtuse angle, so that the second side surface 1132 can be preferably set as an inclined surface inclined relative to the first direction e1, thereby increasing the contact area between the second side surface 1132 and the support block 2132 to improve the support stability and strength.

[0040] According to some embodiments of the present utility model, the first pin hole penetrates through the first connecting portion 113 along the direction in which the second side surface 1132 abuts against the support block 2132, and the second pin hole is formed on the side surface of the support block 2132 that abuts against the second side surface 1132. That is to say, both the first pin hole and the second pin hole extend along the direction in which the second side surface 1132 abuts against the support block 2132, and the limit pin sequentially passes through the first pin hole and the second pin hole along the direction in which the second side surface 1132 abuts against the support block 2132, thereby restricting the relative movement of the first split member 1 and the second split member 2 in the third direction. In addition, by arranging the second pin hole on the support block 2132, the difficulty of opening the second pin hole can be reduced, and at the same time, the influence of the second pin hole on the strength of the second splicing portion 21 can be reduced.

[0041] According to some embodiments of the present utility model, the second limiting structure 112 is formed on the first side surface 1131, and the fourth limiting structure 212 is formed on the third side surface 2131. That is to say, the second limiting structure 112 and the fourth limiting structure 212 are located in the area where the first connecting portion 113 and the second connecting portion 213 face each other in the second direction e2. Thus, the second connecting position formed by the second limiting structure 112 and the fourth limiting structure 212 can be better protected from the relative two sides in the second direction e2 by the first connecting portion 113 and the second connecting portion 213. At the same time, the second connecting position can make full use of the space between the first connecting portion 113 and the second connecting portion 213, and the structure of the splicing position of the first split member 1 and the second split member 2 is compact.

[0042] According to some other embodiments of the present utility model, in the second direction e2, the second limiting structure 112 is formed on the side surface of the first connecting portion 113 that faces away from the first side surface 1131, and the fourth limiting structure 212 is formed on the second side surface 1132 and is located on the side of the second connecting portion 213 that is far away from the first side surface 1131. That is to say, the second connecting position formed by the second limiting structure 112 and the fourth limiting structure 212 is located on the side of the second connecting portion 213 that is far away from the first side surface 1131 in the second direction e2. Thus, it is possible to avoid the second connecting position occupying the space between the first side surface 1131 and the third side surface 2131, and provide sufficient space for the arrangement and mating connection of the first limiting structure 111 and the third limiting structure 211. In addition, the second connecting position can be exposed on the outside, so as to facilitate observing the mating condition of the second limiting structure 112 and the fourth limiting structure 212 to ensure the accurate connection of the cooperation between the second limiting structure 112 and the fourth limiting structure 212.

[0043] According to some embodiments of the utility model, the free end of the first limiting structure 111 matches the shape of the second groove 214, and the free end of the third limiting structure 211 matches the shape of the first groove 114. The shape matching here refers to the same shape and size. In other words, the portion of the first limiting structure 111 located in the second groove 214 is the same shape and size as the second groove 214, and the portion of the third limiting structure 211 located in the first groove 114 is the same shape and size as the first groove 114. Therefore, the free end of the first limiting structure 111 can be prevented from shaking in the second groove 214, and the free end of the third limiting structure 211 can be prevented from shaking in the first groove 114, thereby improving the stability of the connection between the first limiting structure 111 and the third limiting structure 211.

[0044] According to some embodiments of the utility model, the first splicing portion 11 also includes a first connecting portion 113, the first limiting structure 111 and the second limiting structure 112 are arranged along the first direction e1 on one side of the first connecting portion 113 in the second direction e2, the first limiting structure 111 and the second limiting structure 112 and the first connecting portion 113 define a snap-in space, the second splicing portion 21 is located in the snap-in space and includes a second connecting portion 213, and the third limiting structure 211 and the fourth limiting structure 212 are formed on the opposite side sides of the second connecting portion 213 in the first direction e1.

[0045] That is to say, the movement of the second splicing part 21 in the first direction e1 can be better limited by the first limiting structure 111 and the second limiting structure 112. The first connection position formed by the first limiting structure 111 and the third limiting structure 211 is located on one side of the second connection part 213 in the first direction e1, and the second connection position formed by the second limiting structure 112 and the fourth limiting structure 212 is located on the other side of the second connection part 213 in the first direction e1, that is, the first connection position and the second connection position between the first split component 1 and the second split component 2 are respectively located on the opposite sides of the second connection part 213 in the first direction e1, so that the first connection position and the second connection position can make full use of the space on the opposite sides of the second connection part 213 in the first direction e1, thereby avoiding interference in the connection process of the first connection position and the second connection position, so as to reduce the difficulty of assembly between the first split component 1 and the second split component 2.

[0046] According to some embodiments of the present utility model, the first limiting structure 111 and the second limiting structure 112 are arranged at intervals and are formed as hooks bent towards the direction of approaching each other. The first limiting structure 111 and the second limiting structure 112 respectively define a first clamping groove 1112 and a second clamping groove 1122 with the first connecting portion 113. The third limiting structure 211 and the fourth limiting structure 212 are formed as clamping protrusions arranged on the opposite side surfaces of the second connecting portion 213 in the first direction e1. The third limiting structure 211 is clamped in the first clamping groove 1112, and the fourth limiting structure 212 is clamped in the second clamping groove 1122. That is to say, the free end of the first limiting structure 111 is bent towards the direction of approaching the second limiting structure 112, the first clamping groove 1112 is open towards the second limiting structure 112, the free end of the second limiting structure 112 is bent towards the direction of approaching the first limiting structure 111, and the second clamping groove 1122 is open towards the first limiting structure 111. The movement freedom of the third limiting structure 211 in the second direction e2 can be restricted through the first clamping groove 1112, and the movement freedom of the fourth limiting structure 212 in the second direction e2 can be restricted through the second clamping groove 1122. Thus, through the cooperation of the first limiting structure 111 and the third limiting structure 211 and the cooperation of the second limiting structure 112 and the fourth limiting structure 212, the movement freedom of the relative movement of the first split part 1 and the second split part 2 in the first direction e1 and the second direction e2 can be restricted, so as to improve the connection strength of the first split part 1 and the second split part 2.

[0047] According to some embodiments of the present utility model, a first guiding surface 1111 is formed on the side surface of the free end of the first limiting structure 111 facing the second limiting structure 112, and a second guiding surface 1121 is formed on the side surface of the free end of the second limiting structure 112 facing the first limiting structure 111. In the direction from the first connecting portion 113 to the second connecting portion 213, the first guiding surface 1111 and the second guiding surface 1121 extend obliquely in the direction of moving away from each other. That is to say, in the direction from the first connecting portion 113 to the second connecting portion 213, the distance between the first guiding surface 1111 and the second guiding surface 1121 increases. Therefore, during the process of the second splicing portion 21 being inserted into the clamping space, it is convenient for the end portion of the second splicing portion 21 facing the first connecting portion 113 to be inserted between the first guiding surface 1111 and the second guiding surface 1121. The insertion direction of the second splicing portion 21 can be better guided through the first guiding surface 1111 and the second guiding surface 1121, thereby reducing the positioning difficulty of the third limiting structure 211 and the fourth limiting structure 212, and being beneficial to improving the splicing efficiency of the first split part 1 and the second split part 2.

[0048] According to some embodiments of the present utility model, in the direction from the second connecting portion 213 to the first connecting portion 113, the side surface of the third limiting structure 211 facing away from the fourth limiting structure 212 and the side surface of the fourth limiting structure 212 facing away from the third limiting structure 211 extend obliquely in a direction approaching each other. That is to say, in the direction from the second connecting portion 213 to the first connecting portion 113, the height at which the third limiting structure 211 and the fourth limiting structure 212 protrude from the second connecting portion 213 gradually decreases, so that the end of the second splicing portion 21 facing the first connecting portion 113 has a smaller size, facilitating the insertion of the end of the second splicing portion 21 facing the first connecting portion 113 into the splicing space 1133. And under the guidance of the side surface of the third limiting structure 211 facing away from the fourth limiting structure 212 and the side surface of the fourth limiting structure 212 facing away from the third limiting structure 211, the installation direction of the second splicing portion 21 can be better corrected, thereby reducing the positioning difficulty of the third limiting structure 211 and the fourth limiting structure 212, and being beneficial to improving the splicing efficiency of the first split member 1 and the second split member 2.

[0049] According to some embodiments of the present utility model, two limiting blocks 12 are further formed on the side surface of the first connecting portion 113 facing the second connecting portion 213. The two limiting blocks 12 are located between the first limiting structure 111 and the second limiting structure 112 and are respectively in abutment with the third limiting structure 211 and the fourth limiting structure 212 along the first direction e1. That is to say, in the first direction e1, one of the limiting blocks 12 is located on the side of the third limiting structure 211 away from the fourth limiting structure 212 and abuts against the third limiting structure 211 along the first direction e1, and the other limiting block 12 is located on the side of the fourth limiting structure 212 away from the third limiting structure 211 and abuts against the fourth limiting structure 212 along the first direction e1. Therefore, the two limiting blocks 12 can hinder the movement of the second splicing portion 21 in the first direction e1, so as to improve the connection reliability between the first split member 1 and the second split member 2. In a specific example, the side surface of the limiting block 12 corresponding to the third limiting structure 211 facing the third limiting structure 211 is parallel to the side surface of the third limiting structure 211 facing away from the second connecting portion 213, and the side surface of the limiting block 12 corresponding to the fourth limiting structure 212 facing the fourth limiting structure 212 is parallel to the side surface of the fourth limiting structure 212 facing away from the second connecting portion 213, so as to increase the fitting area between the limiting block 12 and the third limiting structure 211 and the fourth limiting structure 212.

[0050] According to some embodiments of the present utility model, the limit stop 12 is spaced apart from the first limit structure 111 and the second limit structure 112. Therefore, it is possible to avoid increasing the deformation difficulty of the first limit structure 111 and the second limit structure 112. Specifically, during the connection process of the first split member 1 and the second split member 2, the first limit structure 111 and the second limit structure 112 can elastically deform in the first direction e1 away from the limit stop 12, so as to facilitate the third limit structure 211 and the fourth limit structure 212 to enter the first clamping groove 1112 and the second clamping groove 1122, which is beneficial to reducing the splicing difficulty of the first split member 1 and the second split member 2.

[0051] According to some embodiments of the present utility model, both the first split member 1 and the second split member 2 are integrally formed parts. Among them, integral forming has the advantages of convenient forming, simple manufacturing, high overall strength and stability. Therefore, by setting the first split member 1 and the second split member 2 as integrally formed parts, the manufacturing difficulty of the first split member 1 and the second split member 2 can be reduced, and at the same time, the strength and stability of the first split member 1 and the second split member 2 can be improved.

[0052] In some embodiments, both the first split member 1 and the second split member 2 are 3D printed parts. Among them, 3D printing can ensure the performance of parts while quickly machining complex parts. Therefore, by forming the first split member 1 and the second split member 2 through 3D printing, the performance of the first split member 1 and the second split member 2 can be ensured while shortening the manufacturing cycle of the first split member 1 and the second split member 2, and the manufacturing efficiency of the first split member 1 and the second split member 2 can be improved.

[0053] According to some embodiments of the present utility model, the limit pin is adapted to be inserted into the second pin hole through the first pin hole, and a reinforcing flange 115 surrounding the outer peripheral side of the first pin hole is formed on the first splicing portion 11, and the reinforcing flange 115 is located on the side of the first pin hole away from the second pin hole. Therefore, the structural strength of the area where the first pin hole is provided on the first splicing portion 11 can be better reinforced through the reinforcing flange 115, so as to reduce the influence of the opening of the first pin hole on the structural strength of the first splicing portion 11.

[0054] According to some embodiments of the present utility model, in the direction from the first pin hole towards the second pin hole, the inner diameters of the first pin hole and the second pin hole and the diameter of the limit pin are reduced. That is to say, the diameter of the insertion end of the limit pin is smaller, and the diameter of the end of the first pin hole away from the second pin hole is larger. Therefore, it is convenient for the limit pin to be inserted into the first pin hole, and at the same time, a good guiding effect can be provided for the insertion of the limit pin, so as to reduce the assembly difficulty of the limit pin with the first splicing portion 11 and the second splicing portion 21.

[0055] In some embodiments, the first split member 1 and the second split member 2 are made of thermoplastic materials. The splicing gap between the first split member 1 and the second split member 2 can be filled by pouring materials such as single-sided hot melting, double-sided hot melting or hot melt adhesive to ensure that the splicing seam between the first split member 1 and the second split member 2 is full, so as to increase the connection strength between the first split member 1 and the second split member 2.

[0056] In other embodiments, the first split member 1 and the second split member 2 are made of thermosetting materials. The splicing gap between the first split member 1 and the second split member 2 can be bonded with quick-drying glue to increase the connection strength between the first split member 1 and the second split member 2.

[0057] In addition, during the process of filling the splicing seam between the first split member 1 and the second split member 2, the surface flatness can be improved by grinding after the filling material solidifies, and multiple fillings and grindings can be carried out according to the filling situation, which is not specifically limited here.

[0068] The trim piece according to the second aspect embodiment of the present invention will be described below with reference to the accompanying drawings.

[0069] The trim piece according to the second aspect embodiment of the present invention includes a split splicing structure 100. Therefore, during the production process of the trim piece, the trim piece can be split into a plurality of first split parts 1 and second split parts 2 for independent molding respectively, so as to reduce the production difficulty of the trim piece. At the same time, through the connection between the first limiting structure 111 and the third limiting structure 211, the connection between the second limiting structure 112 and the fourth limiting structure 212, and the cooperation between the limiting pin and the first pin hole and the second pin hole, the connection positions of the connection areas of the first split part 1 and the second split part 2 can be increased, thereby the strength of the splicing position of the first split part 1 and the second split part 2 can be improved, and further the overall structural strength of the trim piece can be improved.

[0070] The trim piece according to the second aspect embodiment of the present invention has a low production difficulty. At the same time, through the connection between the first limiting structure 111 and the third limiting structure 211, the connection between the second limiting structure 112 and the fourth limiting structure 212, and the cooperation between the limiting pin and the first pin hole and the second pin hole, the connection positions of the connection areas of the first split part 1 and the second split part 2 can be increased, thereby the strength of the splicing position of the first split part 1 and the second split part 2 can be improved, and further the overall structural strength of the trim piece can be improved.

[0071] Specifically, during the split production time:

[0072] Step one, according to the size and performance requirements of the decorative parts and the processing size range of the production and processing equipment, select the appropriate part on the decorative parts for splitting and set the split splicing structure 100 on each segment model according to the structural characteristics. The split splicing structure 100 can be designed according to the characteristics of the actual split parts. According to the common segmentation form, the split splicing structure 100 can be designed into an "I" shape, a "T" shape and an "L" shape, which respectively correspond to the splicing requirements of extending the original features of the split parts, T-shaped transitions and right-angle transitions. Changing the angles of the "T"-shaped and "L"-shaped mortise and tenon structures can achieve transitions at different angles.

[0073] Step 2: 3D printing the first split component 1 and the second split component 2 and the required mortise and tenon joint 3;

[0074] Step 3: Clean the surfaces of the processed first split part 1, the second split part 2 and the required mortise and tenon joint 3, remove impurities on the surfaces, and polish the corners to make them smooth.

[0075] Step 4: Assemble and connect the first split component 1, the second split component 2 and the mortise and tenon joint 3.

[0076] Step 5: Splice and reinforce the seams of the first split part 1 and the second split part 2. For the first split part 1 and the second split part 2 printed by 3D printing using thermoplastic materials, use the same material as the parent material for hot-melt splicing. For the first split part 1 and the second split part 2 printed by 3D printing using thermosetting materials, use quick-drying glue to bond them. Screws and other pins can also be used for reinforcement.

[0077] Step 6: When hot-melt splicing single-layer thermoplastic 3D printed parts, the edges of the first and second parts 1 and 2 need to be melted at the same time, and materials need to be filled as needed to ensure that the seams are full. When hot-melt splicing double-layer, the surface of the overlapping part of the plugging structure needs to be melted as well. The pin structure can be spliced ​​in the form of a seam block, or it can be filled with hot melt adhesive and other materials.

[0078] Step 7: When gluing the first and second parts 1 and 2 printed with thermosetting materials, glue and polish them multiple times to fill the gaps to increase the degree of bonding tightness, and add screws and the like for pin tightening as needed.

[0079] Step 8: The joints after splicing are polished and other treatments are performed to make the joints beautiful and smooth, to ensure a smooth transition between the surfaces of the first split component 1 and the second split component 2, and to fill them again if there are any poor splicing.

[0081] A vehicle according to an embodiment of the third aspect of the present utility model includes: a trim piece.

[0082] For the vehicle according to an embodiment of the third aspect of the present utility model, the production difficulty of the trim piece is low. At the same time, through the connection between the first limiting structure 111 and the third limiting structure 211, the connection between the second limiting structure 112 and the fourth limiting structure 212, and the cooperation between the limiting pin and the first pin hole and the second pin hole, the connection positions of the connection area of the first split piece 1 and the second split piece 2 can be increased, so that the strength of the splicing position of the first split piece 1 and the second split piece 2 can be improved, and further the overall structural strength of the trim piece can be improved.
