In addition, the terms "first", "second", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] The embodiments of the present application provide a host assembly push slide 1000, a host 2000 and a carrier 3000. In a first aspect, the embodiments of the present application provide a host assembly push slide 1000, as shown in Figure 3 The host assembly push slide 1000 is arranged on the host shell 500 of the host 2000 to guide the assembly of the host 2000, improve the assembly efficiency, and the host assembly push slide 1000 can reduce the assembly resistance of the host 2000, further improve the assembly efficiency of the host 2000; as shown in Figure 1 and Figure 2 The host 2000 is installed on the rack 600 of the carrier 3000, and the host 2000 is assembled to the carrier 3000 through the arranged host assembly push slide 1000.

[0041] As shown in Figure 8 and Figure 9 The host assembly push slide 1000 includes a substrate 100 and an enclosing plate 200.

[0042] As shown in Figure 8 and Figure 9 The substrate 100 includes a first end 110, a second end 120, a third end 130 and a fourth end 140. The substrate 100 is a rhombic plate body structure with one long diagonal and one short diagonal. The first end 110 is located at one end of the short diagonal of the substrate 100, and the third end 130 is located at the other end of the short diagonal of the substrate 100, i.e. the first end 110 and the third end 130 are oppositely arranged. The second end 120 is located at one end of the long diagonal of the substrate 100, and the fourth end 140 is located at the other end of the long diagonal of the substrate 100, i.e. the second end 120 and the fourth end 140 are oppositely arranged.

[0043] As shown in Figure 8 and Figure 9 , the surrounding plate 200 is fixedly arranged on the outer edge of the base plate 100 to form a rhombic shell structure. For example, the surrounding plate 200 is fixedly arranged on the outer edge of the base plate 100 by welding, gluing or one-piece molding.

[0044] As shown in Figure 8 and Figure 9 , the surrounding plate 200 includes a guide end 210 and a mounting end 220. The guide end 210 is arranged at the second end 120 and is used to guide the assembly of the host 2000, thereby reducing the time for the host assembly pusher 1000 to align the carrier 3000 and improving the positioning efficiency and assembly efficiency. The mounting end 220 is arranged at the first end 110 and has a rebound gap 180 between the mounting end 220 and the first end 110. After being extruded, the mounting end 220 deforms back to the rebound gap 180. During the assembly of the host 2000, the surrounding plate 200 will contact the carrier 3000 and be extruded, and the mounting end 220 on the surrounding plate 200 will be deformed after being extruded. This can reduce the interaction force between the surrounding plate 200 and the carrier 3000, thereby reducing the resistance of the surrounding plate 200 and improving the assembly efficiency of the host 2000.

[0045] For example, as shown in Figure 9 , a transition plate body is arranged between the guide end 210 and the mounting end 220. The transition plate body is integrally formed between the guide end 210 and the mounting end 220, so as to fixedly connect the guide end 210 and the mounting end 220.

[0046] The design of the host assembly pusher 1000 can guide the assembly of the host 2000, so that the assembly process is smoother, the blindness and errors during assembly are reduced, and the assembly efficiency is improved.

[0047] The rebound gap 180 between the mounting end 220 and the first end 110 allows the mounting end 220 to deform when extruded, thereby further reducing the interaction force between the surrounding plate 200 and the carrier 3000 and reducing the assembly resistance.

[0048] The surrounding plate 200 is fixedly arranged on the outer edge of the base plate 100 to form a rhombic shell structure. This structure design enhances the overall stability and durability of the mechanical structure, so that the pusher is not easy to be damaged during use.

[0049] As shown in Figure 8 and Figure 9As shown, in one embodiment, the mounting end 220 is a C-shaped protruding structure. The C-shaped protruding structure can provide additional support and strength, making the mounting end 220 more durable and less prone to damage when subjected to pressure. The design of the C-shaped protruding structure allows for controlled deformation when the mounting end 220 is subjected to pressure, which can absorb and distribute the force, thereby reducing the interaction force with the carrier 3000 and further reducing the assembly resistance.

[0050] As shown, in one embodiment, the mounting end 220 is a C-shaped protruding structure. The C-shaped protruding structure can provide additional support and strength, making the mounting end 220 more durable and less prone to damage when subjected to pressure. The design of the C-shaped protruding structure allows for controlled deformation when the mounting end 220 is subjected to pressure, which can absorb and distribute the force, thereby reducing the interaction force with the carrier 3000 and further reducing the assembly resistance. Figure 8 As shown, in one embodiment, the mounting end 220 is a C-shaped protruding structure. The C-shaped protruding structure can provide additional support and strength, making the mounting end 220 more durable and less prone to damage when subjected to pressure. The design of the C-shaped protruding structure allows for controlled deformation when the mounting end 220 is subjected to pressure, which can absorb and distribute the force, thereby reducing the interaction force with the carrier 3000 and further reducing the assembly resistance.

[0051] The protruding end 230 and the mounting end 220 are oppositely arranged and both designed as C-shaped protruding structures, which can better balance the stress during assembly. This helps to reduce stress concentration during assembly and improve the stability and durability of the surrounding plate 200.

[0052] As shown, in one embodiment, the mounting end 220 is a C-shaped protruding structure. The C-shaped protruding structure can provide additional support and strength, making the mounting end 220 more durable and less prone to damage when subjected to pressure. The design of the C-shaped protruding structure allows for controlled deformation when the mounting end 220 is subjected to pressure, which can absorb and distribute the force, thereby reducing the interaction force with the carrier 3000 and further reducing the assembly resistance. Figure 8 Figure 9 As shown, in one embodiment, the mounting end 220 is a C-shaped protruding structure. The C-shaped protruding structure can provide additional support and strength, making the mounting end 220 more durable and less prone to damage when subjected to pressure. The design of the C-shaped protruding structure allows for controlled deformation when the mounting end 220 is subjected to pressure, which can absorb and distribute the force, thereby reducing the interaction force with the carrier 3000 and further reducing the assembly resistance.

[0053] The design of the deformation groove 240 reduces the thickness of the mounting end 220, making it easier for the mounting end 220 to deform when subjected to external force. This design helps to better adapt to the shape and size of the carrier 3000 during installation, reducing the resistance and difficulty during assembly.

[0054] By opening the deformation groove 240, the deformation amount of the mounting end 220 is increased. This means that during installation, the mounting end 220 can absorb more assembly errors, thereby improving the reliability and fault tolerance of the assembly, reducing the number of defective products during production, and reducing production costs. The design of the deformation groove 240 reduces the requirement for precise fitting between the mounting end 220 and the carrier 3000. Even if there is a certain deviation in the shape or size of the carrier 3000, the mounting end 220 can adapt to these deviations through deformation, thereby simplifying the assembly process and improving the assembly efficiency.

[0055] Due to the presence of the deformation groove 240, the mounting end 220 can more evenly distribute stress when subjected to external force, reducing the risk of damage caused by stress concentration. This helps to improve the reliability and service life of the mounting end 220.

[0056] ​The design of the deformation groove 240 enables the mounting end 220 to have a certain fault tolerance during assembly. Even if there is a certain error or deviation during assembly, the mounting end 220 can adapt to these errors by deformation, thereby ensuring the success rate and quality of assembly.

[0057] As shown in Figure 8 and Figure 9 , in one embodiment, the substrate 100 and the surrounding plate 200 form a rhombic shell structure with an internal chamber, so that the substrate 100 has a first end face 150 and a second end face 160, as shown in Figure 8 , the first end face 150 is located in the internal chamber of the rhombic shell, and as shown in Figure 9 , the second end 120 is located outside the internal chamber of the rhombic shell structure. The first end face 150 and the second end face 160 are oppositely arranged, and the second end face 160 is provided with a first pin shaft 310 near the protruding end 230. Exemplarily, the second end face 160 abuts against the host 2000, and the first pin shaft 310 is connected with the host 2000. The first pin shaft 310 can lock the substrate 100 in the moving direction.

[0058] Exemplarily, the substrate 100 is fixedly connected with the host 2000 by a bolt, and the first pin shaft 310 can further cooperate with the bolt to lock the substrate 100 in the moving direction and the rotating direction.

[0059] As shown in Figure 3 and Figure 4 , the rhombic shell structure formed by the substrate 100 and the surrounding plate 200 has an internal chamber capable of accommodating the head of the bolt, so that the head of the bolt is located in the rhombic shell, preventing the head of the bolt from blocking the assembly process of the host 2000 and avoiding reducing the assembly efficiency.

[0060] The design of the rhombic shell structure enhances the stability of the overall structure and can withstand greater external force and pressure. At the same time, the setting of the first pin shaft 310 and the cooperation with the bolt further improve the connection reliability between the substrate 100 and the host 2000, and ensure the stability and safety of the mechanical structure during long-term use.

[0061] The design of the internal chamber not only provides sufficient space for the head of the bolt, but also optimizes the space utilization of the overall structure. This design makes the assembly process smoother and improves the assembly efficiency.

[0062] As shown in Figure 9 , in one embodiment, the second end face 160 is further provided with a second pin shaft 320, and the diameter of the first pin shaft 310 is smaller than the diameter of the second pin shaft 320.

[0063] Through the cooperation of the first pin shaft 310 and the second pin shaft 320, the substrate 100 can be more effectively locked to prevent it from deviating or loosening in the moving or rotating direction. This arrangement improves the overall stability of the mechanical structure and ensures the accurate positioning and fixation of the substrate 100.

[0064] As shown in Figure 9 one embodiment, a matching through hole 170 is formed on the substrate 100, and the axis of the matching through hole 170 is parallel to the axes of the first pin shaft 310 and the second pin shaft 320.

[0065] The matching through hole 170 and the first pin shaft 310 are distributed along a first straight line 410, and the matching through hole 170 and the second pin shaft 320 are distributed along a second straight line 420, and the first straight line 410 and the second straight line 420 are perpendicular.

[0066] The perpendicular distribution of the first straight line 410 and the second straight line 420 enables the substrate 100 to be stably supported and locked in both horizontal and vertical directions, thereby ensuring the accurate positioning and fixation of the substrate 100.

[0067] As shown in Figure 8 and Figure 9 in one embodiment, the second end portion 120 and the fourth end portion 140 are provided with rounded corners, and correspondingly, the guide end portion 210 is also provided with rounded corners, reducing stress concentration and reducing the installation resistance of the guide end portion 210.

[0068] In a second aspect, as shown in Figure 3 and Figure 4 the embodiments of the present application also provide a host 2000, which includes a host shell 500 and a host assembly pusher 1000 according to any of the above embodiments.

[0069] As shown in Figure 7 the host shell 500 is provided with a first threaded hole 510, a first pin hole 520 and a second pin hole 530, the first threaded hole 510 and the first pin hole 520 are distributed along a third straight line 430, and the first threaded hole 510 and the second pin hole 530 are distributed along a fourth straight line 440, and the third straight line 430 and the fourth straight line 440 are perpendicular.

[0070] The host assembly pusher 1000 is installed at the first threaded hole 510 of the host shell 500 by a bolt, and the bolt is threadedly connected with the matching through hole 170, and the head of the bolt is located inside the diamond-shaped shell of the host assembly pusher 1000.

[0071] The first pin shaft 310 is installed in the first threaded hole 510, and the second pin shaft 320 is installed in the second pin hole 530.

[0072] In a third aspect, the embodiments of the present application further provide a carrier 3000, comprising a rack 600 and a host 2000 as any of the above embodiments, the rack 600 comprises a mounting slot 610, and the host assembly push slider 1000 is mounted in the mounting slot 610, the mounting end 220 and the protruding end 230 abut the mounting slot 610.
