[0041] See also Figures 1 to 13 As shown, according to an embodiment of the present application, the chassis assembly includes a chassis body 1 and a connecting member 2, a slot 4 and a first connecting hole 5 are provided at a connection position on the chassis body 1, the first connecting hole 5 passes through the slot 4, the connecting member 2 includes a connecting portion 3, the connecting portion 3 is inserted into the slot 4, a second connecting hole 6 is provided on the connecting portion 3, and the first connecting hole 5 and the second connecting hole 6 are provided correspondingly.

[0042] The chassis assembly is divided into two parts, one part is the chassis body 1 formed by an integral mold, and the other part is the separately processed connecting piece 2. After the two parts are formed separately, the connecting piece 2 is installed on the chassis body 1, and the second connecting hole 6 on the connecting piece 2 is aligned with the first connecting hole 5 at the connecting position of the chassis body 1, so that when the chassis assembly and other parts such as the shell are connected, the connecting piece 2 and the chassis body 1 can work together to strengthen the connection, improve the connection strength of the chassis assembly, and achieve a reliable and stable connection; since the connecting piece 2 is processed separately and assembled together after both are formed, rather than added during the mold forming process of the chassis body 1, it is not necessary to put an insert into the chassis body 1 during mold production, which can improve the mold forming efficiency and eliminate the danger of adding the connecting piece 2 during the mold forming process. Since the connecting part of the connecting piece 2 and the chassis body 1 are plug-fitted, the two are in a detachable connection relationship. The connecting piece 2 can be repeatedly installed and disassembled relative to the chassis body 1, so the difficulty of replacing the connecting piece 2 can be reduced, and the replacement cost can be reduced.

[0043] The chassis assembly of the embodiment of the present application is used to connect with other parts to be connected 21, so the connecting member 2 is generally arranged on the periphery of the chassis body 1, so as to facilitate the enhancement of the structural strength of the peripheral connection position of the chassis body 1 and facilitate the connection and fixation between the chassis body 1 and the parts to be connected 21 through the connecting member 2.

[0044] The slot 4 gradually narrows along the insertion direction, and the shape of the connection part 3 is adapted to the slot 4. The slot 4 gradually narrows along the insertion direction, and can form a structure that is larger at the top and smaller at the bottom, which is convenient for guiding the insertion of the connection part 3 into the slot 4, and can effectively avoid the phenomenon of the connection part 3 being stuck, and facilitate the installation and disassembly between the connection part 3 and the chassis body 1. The role of the slot 4 here is mainly to position the connection part 3, prevent the connection part 3 from rotating and the second connection hole 6 from axial displacement, and improve the stability and reliability of the installation structure of the connection part 3. The second connection hole 6 is a bolt hole here, which is used to provide a screw tightening position for the installation and fixation between the connected part 21 and the chassis assembly.

[0045] The slot 4 gradually narrows along the insertion direction. The slot 4 may be gradually narrowed along the length direction of the cross section, or along the width direction of the cross section, or in both directions at the same time.

[0046] In one embodiment, the width of the slot 4 decreases along a direction away from the opening of the slot 4 .

[0047] The angle between the two side walls in the width direction of the slot 4 is α, where 5°≤α≤20°. This can prevent the angle from being too small, which will result in the inclination angle formed between the two side surfaces of the slot 4 being too small and thus failing to play an effective guiding role. It can also prevent the inclination angle from being too small, which will result in the width difference between the opening and the bottom of the slot 4 being too large, thus limiting the depth of the slot 4 and making it impossible to ensure the insertion depth of the connecting part 3 in the slot 4.

[0048] A second folding arm 8 is provided on at least one insertion side of the connecting portion 3, and the shape of the second folding arm 8 is adapted to the shape of the side wall of the slot 4 corresponding to the second folding arm 8. Along the direction away from the slot 4 opening, the width of the second folding arm 8 decreases, so that the second folding arm 8 forms a guiding structure with a larger upper part and a smaller lower part.

[0049] In this embodiment, second folding arms 8 are respectively provided on the two insertion sides of the connecting part 3. On the one hand, their function is to improve the structural strength of the connecting part 3 and enhance the firmness of the connecting part 3 during installation. On the other hand, the second folding arms 8 adopt a structure with a larger upper part and a smaller lower part, which can also play a guiding role during installation, making it convenient to insert the connecting part 3 into the slot 4 of the chassis body 1.

[0050] In one embodiment, the connection portion 3 includes a plurality of folding plates 9 connected in sequence, and the second connection hole 6 is provided on one or more of the folding plates 9. In this embodiment, a bent plate structure is formed by connecting a plurality of folding plates, thereby increasing the contact area between the connection portion 3 and the slot 4 and improving the firmness of the installation.

[0051] In one embodiment, a barb 10 is provided on the side wall of the folding plate 9 , and a hook groove 11 is provided at a corresponding position on the side wall of the slot 4 .

[0052] When the folding plate 9 is inserted into the slot 4, the barb 10 on the folding plate 9 is inserted into the hook groove 11 on the side wall of the slot 4, so that a hooking effect is formed between the folding plate 9 and the side wall of the slot 4, which plays an effective anti-slip effect and can enable the folding plate 9 to be stably maintained in the slot 4.

[0053] In one embodiment, a hook groove 11 is provided on the side wall of the folding plate 9 , and a barb 10 is provided at a corresponding position on the side wall of the slot 4 .

[0054] In one embodiment, a first baffle 22 is provided on one side of the connection part 3 close to the opening of the slot 4, and an anti-slip protrusion 12 is provided on the chassis body 1, and the first baffle 22 stops on one side of the anti-slip protrusion 12 close to the slot 4. After the multiple folding plates 9 of the connection part 3 enter the slot 4, the first baffle 22 located at the top of the connection part 3 is inserted under the anti-slip protrusion 12 on the chassis body 1, and the anti-slip protrusion 12 forms a stopper, so that the connection part 3 can be limited from the top of the connection part 3 to prevent the connection part 3 from slipping out of the slot 4.

[0055] In one embodiment, the connector 2 further includes a mounting portion 13, the connector 3 is fixedly connected to the mounting portion 13, and the mounting portion 13 is fixedly mounted on the chassis body 1. The mounting portion 13 is fixedly mounted on the chassis body 1 in a detachable manner, and since the connector 3 is also detachably mounted on the chassis body 1, the connector 2 including the mounting portion 13 and the connector 3 is still detachably connected to the chassis body 1 as a whole, and can be easily replaced and repaired, thereby improving the replacement and repair efficiency and reducing the replacement and repair costs.

[0056] In one embodiment, the mounting portion 13 includes a mounting plate 14, a mounting groove 15 is provided on the chassis body 1, and the mounting plate 14 is disposed in the mounting groove 15 and is detachably fixedly connected to the chassis body 1. In this embodiment, by providing the mounting groove 15, the mounting groove 15 can be used to limit the installation of the mounting plate 14, and the installation of the mounting plate 14 is conveniently positioned, so that the mounting plate 14 can be quickly and accurately installed on the chassis body 1.

[0057] The mounting groove 15 is provided with an anti-dropout protrusion 12 at the opening position. The anti-dropout protrusion 12 protrudes from the side wall of the mounting groove 15 and forms an anti-dropout slot 16 with the bottom wall of the mounting groove 15. The mounting plate 14 is located in the anti-dropout slot 16 and is limited by the anti-dropout protrusion 12. The anti-dropout protrusion 12 here can be directly formed when the chassis body 1 is molded. During installation, one side of the mounting plate 14 can be first inserted into the anti-dropout slot 16, and the connecting part 3 can be dropped into the slot 4 at the same time. Then, the other side of the mounting plate 14 can also be inserted into the anti-dropout slot 16, so that the connecting part 3 is also installed in place in the slot 4. Since the width of the anti-dropout protrusion 12 is smaller than the width of the mounting plate 14, when the mounting plate 14 is installed in the anti-dropout slot 16, it will be limited by the anti-dropout protrusion 12 and cannot be removed from the mounting groove 15, thereby playing an effective anti-dropout role.

[0058] The mounting portion 13 further includes a first folding arm 7, which is connected to the side of the mounting plate 14 and is bent in a direction away from the bottom wall of the mounting groove 15. The first folding arm 7 is located in the anti-dropping groove 16 and is limited by the anti-dropping protrusion 12. In this embodiment, there are three first folding arms 7, which are respectively located on the other three sides of the mounting portion 13 except the connection side connected to the connection portion 3, which can improve the structural strength of the mounting plate 14 of the mounting portion 13, and at the same time increase the contact area between the mounting portion 13 and the side wall of the mounting groove 15, thereby increasing the firmness of the mounting portion 13 installed on the chassis body 1.

[0059] The height of the anti-dropout protrusion 12 beyond the side wall of the mounting groove 15 is 1.5 mm to 3 mm, and the thickness of the first folding arm 7 is the same as the height of the anti-dropout protrusion 12 beyond the side wall of the mounting groove 15, or slightly less than the height of the anti-dropout protrusion 12 beyond the side wall of the mounting groove 15, thereby ensuring that the first folding arm 7 can be completely located in the anti-dropout slot 16, providing sufficient anti-dropout structural strength. In this embodiment, the height of the first folding arm 7 is equivalent to the height of the anti-dropout slot 16, so that the first folding arm 7 can form a stable matching effect after being inserted into the anti-dropout slot 16, facilitating the installation and assembly between the connector 2 and the chassis body 1.

[0060] In one embodiment, a mounting hole 17 is provided at the bottom of the mounting groove 15, and a third connecting hole 19 is provided on the mounting portion 13. The third connecting hole 19 is provided corresponding to the mounting hole 17, and a bolt 20 is provided in the third connecting hole 19. The bolt 20 is installed in the mounting hole 17. In this embodiment, the mounting portion 13 and the chassis body 1 are both provided with connecting holes, so the mounting portion 13 and the chassis body 1 can be fixedly connected together by the bolt 20. In order to prevent the bolt 20 from rusting due to long-term use, the bolt 20 can be a plastic bolt.

[0061] In one embodiment, the mounting plate 13 is further provided with an adsorption surface, which enables the connector 2 to be grasped by suction as a whole, thereby facilitating automated assembly and improving the assembly efficiency between the chassis body 1 and the connector 2 .

[0062] The third connecting hole 19 serves as a position for screw-fixing the connecting member 2 and provides a place for automated grabbing by automated equipment.

[0063] In one embodiment, a plastic bolt 18 is installed in the mounting hole 17, the plastic bolt 18 is screwed with the mounting hole 17, the plastic bolt 18 has a threaded hole, and the bolt 20 is installed in the threaded hole. In this embodiment, by adding the plastic bolt 18 between the mounting portion 13 and the mounting hole 17 of the chassis body 1, the plastic bolt 18 can be used to form an intermediate transfer function, so that it is convenient to process the structure between the chassis body 1 and the mounting portion 13, and the plastic bolt 18 can be used to protect the chassis body 1, so that the bolt 20 can only directly act on the plastic bolt 18, and will not directly act on the chassis body 1, so that the problem of the chassis body 1 cracking due to the excessive tightening force of the bolt 20 will not occur. In addition, since the bolt 20 is not directly connected to the chassis body 1, the bolt 20 can also be a metal bolt. In this way, even if the bolt 20 is rusted, it only needs to unload the plastic bolt 18 from the mounting hole 17 to realize the unloading of the connecting member 2 from the chassis body 1, and the phenomenon of being unable to be disassembled due to the rust of the bolt can be avoided.

[0064] The plastic bolt 18 has an external thread on the outside and a threaded hole on the inside. The mounting hole 17 has a threaded hole, so it is convenient to achieve a fixed connection between the plastic bolt 18 and the mounting hole 17, and between the mounting portion 13 and the plastic bolt 18.

[0065] In one embodiment, the chassis component is made of a foam material, such as EPP, EPPE or EPO.

[0066] In one embodiment, the connecting member 2 is a metal connecting flap.

[0067] The connecting member 2 is, for example, an L-shaped folded plate structure.

[0068] When assembling the connector 2 and the chassis body 1, the plastic bolt 18 can be first rotated into the mounting hole 17 at the bottom of the mounting groove 15 of the chassis body 1, and then the mounting portion 13 of the connector 2 is installed into the mounting groove 15 of the chassis body 1, and the first folding arm 7 is inserted into the anti-dropping slot 16, and the connecting portion 3 enters the slot 4, so that the connector 2 is installed in place on the chassis body 1. Then the bolt 20 is installed in the third connecting hole 19 and the plastic bolt 18, so that the connecting portion 3 is fixedly connected to the chassis body 1, and the combination between the connector 2 and the chassis body 1 is realized. After that, the component 21 to be connected, such as the housing, can be placed on the chassis body 1, the housing can be fastened to the chassis body 1 with screws, and the screws are fixed to the connector 2, so as to realize the connection and fixation between the chassis assembly and the component 21 to be connected.

[0069] In this embodiment, a plurality of connectors 2 are installed on the circumferential side of the chassis body 1, so that the connection structure between the chassis body 1 and the component to be connected 21 can be strengthened from multiple locations, further improving the connection strength and working performance of the chassis assembly.
