[0030] In order to better understand the above-mentioned technical scheme, the technical scheme of the embodiments of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the embodiments of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0031] The first aspect of the present application provides a satellite bracket 10, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the satellite bracket 10 includes: a base 100, at least two positioning parts 200 and a fixing part 300, the positioning part 200 is located on the base 100, the positioning part 200 is used to limit the functional component 20, the fixing part 300 is connected to the positioning part 200, and the fixing part 300 is used to snap into the functional component 20, wherein the base 100, the positioning part 200 and the fixing part 300 are processed into an integrated structure by additive manufacturing technology.

[0032] In this embodiment, the satellite bracket 10 is used to support the functional component 20 in the satellite device. For example, the functional component 20 can be a circuit board or a battery pack. The positioning part 200 is arranged at the end of the base 100. The positioning part 200 can cooperate with the functional component 20, so as to limit the functional component 20. The fixing member 300 is located at the end of the positioning part 200. The fixing member 300 extends out of the positioning part 200 and is engaged with the functional component 20. Therefore, the freedom of the functional component 20 is constrained by the positioning part 200 and the fixing member 300, so as to realize the positioning of the functional component 20 and improve the stability of the functional component 20 in the working state.

[0033] The base 100, the positioning part 200 and the fixing part 300 are processed into an integrated structure by additive manufacturing technology. For example, the additive manufacturing technology can be 3D printing technology. First, the base 100 and the positioning part 200 are manufactured by additive manufacturing, and then the functional component 20 is placed on the base 100. During the placement process, the positioning part 200 cooperates with the functional component 20 so that the positioning part 200 can limit the functional component 20. Finally, the fixing part 300 is manufactured at the end of the positioning part 200 by additive manufacturing, so that the fixing part 300 is snapped with the functional component 20 to constrain the spatial position of the functional component 20 and ensure the stability of the functional component 20.

[0034] Additive manufacturing technology is efficient, flexible and integrated. Compared with the manufacturing method of the prior art, it has a high degree of manufacturing freedom, so that the satellite bracket 10 can be embedded with the functional component 20 during the additive manufacturing process, and then the additive manufacturing technology is combined with the automated embedding technology, so that the satellite bracket 10 can constrain the position of the functional component 20 during the additive manufacturing process, and realize the integrated manufacturing of the structure and function of the satellite bracket 10, so that the positioning part 200 and the fixing part 300 can position the functional component 20 more accurately and firmly. In addition, the additive manufacturing technology eliminates the assembly process and improves the manufacturing efficiency of the satellite bracket 10.

[0035] In some embodiments provided in this application, Figure 1 As shown, optionally, the number of the bases 100 is at least two, the two bases 100 are cross-connected, and two ends of any base 100 are respectively connected to two positioning portions 200 .

[0036] In this embodiment, the base 100 extends in a straight line, and two cross-connected bases 100 form an X shape. Two positioning portions 200 are respectively manufactured at both ends of each base 100 by additive manufacturing. The two bases 100 are symmetrically arranged. The base 100 can ensure the relative position of each positioning portion 200, so that a parallel polygon is formed between the multiple positioning portions 200, and the positioning portions 200 are distributed on the vertex angles of the functional component 20.

[0037] The functional component 20 may be a PCB board, such as Figure 2 and Figure 3 As shown, one positioning portion 200 can constrain the translational movement of the functional component 20 along the X and Y directions, as well as the rotation around the X and Y directions. The two diagonally distributed positioning portions 200 can work together to limit the rotation of the functional component 20 around the Z direction. The four positioning portions 200 can ensure the limiting effect of the positioning portion 200 and ensure the smoothness of the embedding process of the functional component 20.

[0038] In some embodiments provided in this application, Figure 2 , Figure 3 and Figure 4 As shown, optionally, the positioning portion 200 can pass through the functional component 20 so that the functional component 20 is located between the fixing member 300 and the base 100 .

[0039] In this embodiment, the outer periphery of the functional component 20 is provided with a through hole, and the positioning part 200 can pass through the through hole. For example, the positioning part 200 can be a cylindrical pin, and the cylindrical pin structure can avoid the step effect of additive manufacturing. The two ends of any positioning part 200 are respectively connected to the fixing member 300 and the base 100, and the fixing member 300 extends out of the positioning part 200 in the horizontal direction, so that the functional component 20 is fixed between the fixing member 300 and the base 100 to hinder the translation and rotation of the functional component 20 in all directions, thereby constraining the spatial position of the functional component 20.

[0040] In some embodiments provided in the present application, optionally, the satellite bracket 10 further includes: a connecting piece, one side of which can be bonded to the functional component 20 , and the other side of which can be connected to the fixing piece 300 .

[0041] In this embodiment, the connecting piece is first bonded to one side of the functional component 20, and then the functional component 20 is placed on the base 100 and connected to the fixing piece 300, so that the connecting piece is located between the functional component 20 and the fixing piece 300. The connecting piece can adjust the friction force and preload force between the fixing piece 300 and the functional component 20, thereby improving the clamping strength and enhancing the reliability of the fixation.

[0042] Exemplarily, the connecting piece may be a masking paper or a double-sided tape, and the connecting piece may be bonded to the fixing piece 300 .

[0043] In some embodiments provided in this application, Figure 6 and Figure 7 As shown, optionally, the positioning portion 200 is a groove, and two grooves are arranged oppositely on the two bases 100, and both ends of the functional component 20 can extend into the two grooves, and the fixing member 300 connects the grooves on both sides.

[0044] In this embodiment, when the functional component 20 is placed vertically, illustratively, the functional component 20 may be a battery pack. Figure 5 As shown, the overhang angle A between the axis of the positioning structure and the vertical direction is too large. Due to the limitation of the additive manufacturing process, the horizontal hole positioning structure cannot be directly printed. Therefore, the satellite bracket 10 of the vertically placed functional component 20 adopts a planar positioning method.

[0045] The positioning portion 200 is a groove, and the groove and the base 100 extend in the same direction. A spacing is provided between the two bases 100 so that the notches of the two grooves are opposite to each other, and the two ends of the functional component 20 are respectively embedded in the grooves on both sides. The fixing member 300 is located on the bottom wall of the base 100 and connects the grooves on both sides. After the functional component 20 moves to the bottom of the base 100 along the extending direction of the groove, it is engaged with the fixing member 300, thereby realizing the spatial positioning of the functional component 20.

[0046] In some embodiments provided in this application, Figure 7 As shown, optionally, the satellite bracket 10 also includes: a support member 400, the support member 400 is connected to the base 100, and the distance between the end face of the support member 400 facing away from the base 100 and the base 100 gradually increases in the direction approaching the bottom, and the bottom end face of the support member 400 is coplanar with the bottom end face of the base 100.

[0047] In this embodiment, the support member 400 is connected to the side of the base 100 where no groove is set, the bottom end surface of the support member 400 is on the same plane as the bottom end surface of the base 100, and the bottom of the support member 400 expands outward, thereby improving the supporting strength of the satellite bracket 10 for the functional component 20 and ensuring the fixing effect of the satellite bracket 10.

[0048] Exemplarily, there may be a plurality of support members 400 , and the plurality of support members 400 are distributed along the circumference of the base 100 .

[0049] In a second aspect of the present application, an embodiment provides a method for manufacturing a satellite bracket, such as Figure 8 As shown, the manufacturing method of the satellite bracket is used to manufacture the satellite bracket provided by any one of the first aspect embodiments above, and the manufacturing method of the satellite bracket includes:

[0050] Step 101, manufacturing a base and at least two positioning parts by additive manufacturing, wherein the positioning parts are located on the base;

[0051] Step 102, matching the functional component with the positioning portion so that the positioning portion limits the functional component;

[0052] Step 103, manufacturing a fixing piece on the positioning portion by means of additive manufacturing, so that the fixing piece is engaged with the functional component.

[0053] In this embodiment, a base and a positioning portion are first manufactured by additive manufacturing, and then a functional component is placed on the base. During the placement process, the positioning portion cooperates with the functional component so that the positioning portion can limit the functional component. Finally, a fixing piece is manufactured at the end of the positioning piece by additive manufacturing, and the fixing piece is snap-fitted with the functional component to constrain the spatial position of the functional component and ensure the stability of the functional component.

[0054] Additive manufacturing technology is efficient, flexible and integrated. Compared with the manufacturing methods of the existing technology, it has a high degree of manufacturing freedom, which enables the satellite bracket to embed functional components during the additive manufacturing process, and then combines additive manufacturing technology with automated embedding technology, so that the satellite bracket can constrain the position of the functional components during the additive manufacturing process, and realize the integrated manufacturing of the structure and function of the satellite bracket, so that the positioning part and the fixing parts can position the functional components more accurately and firmly. In addition, additive manufacturing technology eliminates the assembly process and improves the manufacturing efficiency of the satellite bracket.

[0055] In some embodiments provided in the present application, optionally, the step of manufacturing the base and at least two positioning parts by additive manufacturing specifically includes: manufacturing at least two bases so that the two bases are cross-connected; manufacturing two positioning parts at both ends of any base by additive manufacturing. The step of matching the functional component with the positioning part specifically includes: the positioning part passes through the functional component.

[0056] In this embodiment, the base extends in a straight line, and two cross-connected bases form an X shape. Two positioning parts are respectively manufactured at both ends of each base by additive manufacturing. The two bases are symmetrically arranged. The base can ensure the relative position between the positioning parts, so that a plurality of positioning parts form parallel polygons, and the positioning parts are distributed on the top corners of the functional components. The four positioning parts can ensure the limiting effect of the positioning parts and ensure the stability of the functional component embedding process.

[0057] The outer periphery of the functional component is provided with a through hole, and the positioning part can pass through the through hole. For example, the positioning part can be a cylindrical pin. The two ends of any positioning part are respectively connected to the fixing part and the base. The fixing part extends out of the positioning part in the horizontal direction, so that the functional component is fixed between the fixing part and the base to hinder the translation and rotation of the functional component in all directions, thereby constraining the spatial position of the functional component.

[0058] In some embodiments provided in the present application, optionally, before the step of matching the functional component with the positioning portion, the step further includes: bonding a connecting member to a side where the functional component is connected to the fixing member.

[0059] In this embodiment, the connecting part is first bonded to one side of the functional component, and then the functional component is placed on the base and connected to the fixing part so that the connecting part is located between the functional component and the fixing part. The connecting part can adjust the friction and preload force between the fixing part and the functional component, thereby improving the clamping strength and enhancing the reliability of the fixation.

[0060] In some embodiments provided in this application, Figure 6 As shown, optionally, the step of manufacturing a base and at least two positioning parts by additive manufacturing specifically includes: manufacturing at least two bases and two positioning parts, the positioning parts are grooves, and the two grooves are arranged opposite to each other. The step of matching the functional component with the positioning part specifically includes: extending the two ends of the functional component into the two grooves. After the step of manufacturing a fixing part on the positioning part by additive manufacturing, it also includes: manufacturing a support part on the base by additive manufacturing, the distance between the end face of the support part facing away from the base and the base gradually increases in the direction close to the bottom, and the bottom end face of the support part is coplanar with the bottom end face of the base.

[0061] In this embodiment, the positioning portion is a groove, and the groove and the base extend in the same direction. A spacing is provided between the two bases so that the notches of the two grooves are opposite to each other, and the two ends of the functional component are respectively embedded in the grooves on both sides. The fixing piece is located on the bottom wall of the base and connects the grooves on both sides. After the functional component moves to the bottom of the base along the extending direction of the groove, it is engaged with the fixing piece, thereby realizing the spatial positioning of the functional component.

[0062] The support member is connected to the side of the base where no groove is set, the bottom end surface of the support member and the bottom end surface of the base are on the same plane, and the bottom of the support member expands outward, which improves the supporting strength of the satellite bracket to the functional components and ensures the fixing effect of the satellite bracket.

[0063] In a specific embodiment, the assembly process is eliminated by combining additive manufacturing and automated embedding technology to achieve integrated manufacturing of the product's structure and function. At the same time, in the overall additive manufacturing process, there are no assembly fasteners to constrain the spatial position of the components. The process positions and fixes the functional components, achieving effective constraints on the functional components.

[0064] Under the premise of positioning and fixing the six degrees of freedom of the functional component space, combined with experimental experience and printing technology, the Fig. 9 The idea shown is to design the bracket of the functional component: the fixing form is mainly based on the cooperation of the functional component and the insulating support structure. Referring to the positioning and fixing methods of the workpiece in machining, the positioning and fixing methods of each typical functional component based on the cooperation method are enumerated, and its feasibility is verified through experiments. If the cooperation method can achieve the positioning and fixing functions during the experiment, but there are obvious defects in the fixing effect, try to pre-process the embedded parts, such as sticking masking paper and double-sided tape on the surface of the functional component, to ensure that the bracket can better fix the functional component. If the tolerance cooperation fixing method cannot be achieved due to reasons such as the printing process and the shape of the functional component, other forms and principles are used to redesign the bracket.

[0065] In the design process of the bracket, due to fewer restrictions and higher design freedom, it is necessary to follow certain principles and methods, and adopt the method of "first positioning, then fixing, and then optimizing" to carry out the design work of the bracket. That is, first locate the six degrees of freedom of the space of the functional component, then design the fixing parts based on the positioning form, and then consider the constraints of the additive manufacturing process and the connection method of the conductive line, optimize the positioning and fixing structure, and then obtain the design of the functional component bracket under a working condition, carry out experiments, verify the feasibility of the bracket and carry out corresponding iterations.

[0066] 1. PCB board hole positioning bracket design:

[0067] There are through holes for assembly and fixation around the PCB board. The six degrees of freedom of the PCB board are constrained by means of the through holes on the PCB board, and the method of printing-embedding-reprinting is adopted. In order to ensure the stability of the embedding process, the design of fixing all four through holes can be adopted. The pause program is set in the pause embedding layer. After printing the positioning part, the PCB board is embedded, and then the fixing parts are continued to be printed to complete the fixation of the PCB board. The experimental results show that the satellite bracket can constrain the six degrees of freedom of the PCB board, and the fixing effect is good. The combination of the fixing part and the upper surface of the PCB board is not good. The bonding problem of the fixing part is solved by sticking masking tape around the positioning holes of the PCB board. By increasing the bottom area of ​​the fixing part and increasing the contact area between the fixing part and the masking tape, the warping problem caused by low friction is solved.

[0068] 2. Battery Pack Bracket Design

[0069] The battery pack is assembled and fixed by the PCB board behind it. In the vertical placement condition, after the bracket is printed, the battery pack is inserted between the two positioning plates, and then the fixing parts are printed. Since the center of gravity of the vertically placed battery pack is relatively high, the fixing parts are improved based on the consideration of the stability of the bracket printing, and support structures are added on both sides of the bracket. The experimental results show that the plane fixing method can effectively position and fix the vertically placed battery pack, and the fixing effect is good.
