Detailed Implementation

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] This utility model embodiment provides a chassis 1000, such as Figure 1-3 As shown, the chassis 1000 includes: a housing 100, a partition assembly 200, and a connecting assembly 300. One side of the housing 100 has an opening 101 for placing a function card. The partition assembly 200 is disposed inside the housing 100 and includes a horizontal plate 201 and at least one vertical plate 202. The opposite sides of the horizontal plate 201 are respectively connected to the opposite inner walls of the housing 100. One end of the vertical plate 202 is slidably connected to the horizontal plate 201, and the other end is slidably connected to the inner wall of the housing 100. The connecting assembly 300 is disposed inside the housing 100 and on the horizontal plate 201. The vertical plate 202 is slidably connected to the connecting assembly 300.

[0027] A partition assembly 200 is installed inside the chassis 1000, including a horizontal plate 201 and a vertical plate 202. The two sides of the horizontal plate 201 are connected to the inner walls of the two sides of the housing 100, respectively. One end of the vertical plate 202 is slidably connected to a connecting component 300 on the horizontal plate 201, and the other end is slidably connected to a connecting component 300 on the inner wall of the housing 100. This design ensures a stable connection between the vertical plate 202, the horizontal plate 201, and the housing 100, while also enabling quick installation and disassembly, thus improving the convenience of the chassis 1000. Furthermore, one or more vertical plates 202 can be installed on the horizontal plate 201 to accommodate function cards of different sizes, thereby enhancing the applicability and operability of the chassis 1000 to meet usage requirements in various situations.

[0028] It should be noted that the horizontal plate 201 divides the internal space of the chassis 1000 into upper and lower layers. Therefore, by setting different numbers of vertical plates 202 inside, different numbers of slots can be created to meet the installation requirements of functional daughter cards of different models and sizes. For example, if one vertical plate 202 is set in each layer, it will be divided into four slots; if two vertical plates 202 are set in each layer, it will be divided into six slots; if three vertical plates 202 are set in each layer, it will be divided into eight slots; or if no vertical plates 202 are set, only the horizontal plate 201 will be used to divide the space into upper and lower slots.

[0029] The detachable connection between the horizontal plate 201 and the vertical plate 202 allows for a variety of combinations of the partition assembly 200, providing multiple options for the space division within the chassis 1000. This makes the layout of the functional sub-cards within the chassis 1000 more flexible and improves the applicability of the chassis 1000.

[0030] Specifically, the vertical plate 202 is slidably connected to the horizontal plate 201 and the housing 100, making it easy to install and remove the vertical plate 202. This allows the chassis 1000 to meet different usage conditions and makes the maintenance and repair of the chassis 1000 more convenient. Inspections can be carried out quickly by removing the vertical plate 202, saving installation and maintenance costs.

[0031] refer to Figure 2 The connecting component 300 includes a first rivet 301 and a second rivet 302. The first rivet 301 is disposed inside the housing 100, and the second rivet 302 is disposed on the horizontal plate 201. Sliding grooves 203 are respectively provided on opposite sides of the vertical plate 202, wherein one sliding groove 203 is slidably connected to the first rivet 301, and the other sliding groove 203 is slidably connected to the second rivet 302.

[0032] The first rivet 301 is located inside the housing 100, and the second rivet 302 is located on the horizontal plate 201. Therefore, when the vertical plate 202 needs to be slidably connected with the housing 100 and the horizontal plate 201, the sliding grooves 203 provided on opposite sides of the vertical plate 202 are slidably connected with the first rivet 301 and the second rivet 302 respectively. This ensures quick connection and installation between the vertical plate 202, the horizontal plate 201, and the housing 100, and improves the operability of the overall chassis 1000.

[0033] It is easy to understand that the vertical plate 202 is slidably connected to the first rivet 301 and the second rivet 302 respectively through the sliding groove 203, which makes the assembly and disassembly of the vertical plate 202 more convenient, allows for quick installation or replacement of components, and improves installation efficiency and maintenance convenience.

[0034] refer to Figure 3 The vertical plate 202 is provided with a spring 206, and the opposite sides of the spring 206 are provided with buckles 2061, one buckle 2061 can abut against the first rivet 301, and the other buckle 2061 can abut against the second rivet 302.

[0035] The spring 206 has buckles 2061 on each side. The buckles 2061 are used to abut against the first rivet 301 and the second rivet 302 to limit the movement, which can ensure a stable connection between the vertical plate 202 and the horizontal plate 201, as well as between the vertical plate 202 and the chassis 1000, and enhance the stability of the chassis 1000 structure.

[0036] The buckle 2061 design allows the vertical plate 202 to be restricted to the required position by the connecting component 300, enabling it to move within the design range and preventing the vertical plate 202 from shaking or shifting.

[0037] refer to Figure 4The buckle 2061 is provided with a guide slope 20611, which faces the first rivet 301 and the second rivet 302 respectively. The guide slope 20611 is used to guide the buckle 2061 to move relative to the first rivet 301 and the second rivet 302.

[0038] The guide ramp 20611 can precisely guide the movement of the buckle 2061 relative to the first rivet 301 and the second rivet 302, respectively, ensuring that the buckle 2061 can move relative to the first rivet 301 and the second rivet 302 due to the guidance of the guide ramp 20611, thereby enabling the buckle 2061 to move to the other side of the first rivet 301 and the second rivet 302, achieving the limiting effect between the buckle 2061 and the connecting component 300.

[0039] In actual use, the sliding grooves 203 on opposite sides of the vertical plate 202 are slidably connected to the first rivet 301 and the second rivet 302, respectively. When the first rivet 301 and the second rivet 302 come into contact with the buckle 2061, the first rivet 301 and the second rivet 302 are pressed by manual squeezing, causing the spring 206 to undergo elastic deformation. During this process, the buckle 2061 is guided to move relative to the first rivet 301 and the second rivet 302 by the guide slope 20611 until it moves to the other side of the first rivet 301 and the second rivet 302. At this time, the buckle 2061 restores its elastic deformation and abuts against the first rivet 301 and the second rivet 302, thereby achieving the effect of fixing and limiting the vertical plate 202.

[0040] refer to Figure 3 The vertical plate 202 also includes a first connecting piece 204, a fixing member 207 and a second connecting piece 205 that are connected to each other. The first connecting piece 204 and the second connecting piece 205 are fixedly connected by the fixing member 207. The spring piece 206 is disposed between the first connecting piece 204 and the second connecting piece 205. The sliding groove 203 is located on the opposite side edges between the first connecting piece 204 and the second connecting piece 205.

[0041] The first connecting piece 204 and the second connecting piece 205 are fixedly connected by a fastener 207, which enhances the connection strength between them. A spring 206 is positioned between the first connecting piece 204 and the second connecting piece 205, preventing it from wobbling or shifting during use and ensuring its intended elastic function. A sliding groove 203 is also provided between the first connecting piece 204 and the second connecting piece 205. This arrangement enhances the overall structural strength and stability of the vertical plate 202, ensuring its secure placement within the chassis 1000.

[0042] The position of the spring 206 helps to ensure the stability of the spring 206 on the vertical plate 202, ensure the firmness of the connection, and at the same time ensure the elasticity of the spring 206 to realize the deformation and guidance of the buckle 2061.

[0043] refer to Figure 4 The spring 206 includes a connecting section 2062 and an unlocking section 2063 that are connected to each other. The connecting section 2062 is fixedly connected to the first connecting piece 204. The buckle 2061 is provided on opposite sides of the connecting section 2062. The first connecting piece 204 is provided with a receiving groove 2041. The buckle 2061 is located in the receiving groove 2041. The first connecting piece 204 is provided with a first slot 2042. The second connecting piece 205 is provided with a second slot 2051 corresponding to the first slot 2042. The unlocking section 2063 is located in the first slot 2042 and the second slot 2051.

[0044] The spring 206 is fixedly connected to the connecting section 2062 to ensure the connection stability of the spring 206. A receiving groove 2041 is provided on the first connecting piece 204, and a buckle 2061 is disposed within the receiving groove 2041. The receiving groove 2041 provides a certain amount of movement space for the buckle 2061, allowing for a certain range of movement for the deformation of the spring 206 when the buckle 2061 abuts against the first rivet 301 and the second rivet 302 respectively. A first slot 2042 is provided on the first connecting piece 204, and a second slot 2051 corresponding to the first slot 2042 is provided on the second connecting piece 205. An unlocking section 2063 is disposed within the first slot 2042 and the second slot 2051, allowing the user to press the unlocking section 2063 through the first slot 2042 and the second slot 2051 to unlock the buckle 2061, thereby enabling the vertical plate 202 to slide relative to the housing 100.

[0045] In actual use, during the installation of the vertical plate 202, the vertical plate 202 slides relative to the horizontal plate 201 and the housing 100. When the latches 2061 on opposite sides of the vertical plate 202 abut against the first rivet 301 and the second rivet 302 respectively, the user-applied external force forces the spring 206 to undergo elastic deformation, allowing the vertical plate 202 to move smoothly to the desired position. Then, the first rivet 301 and the second rivet 302 respectively limit and fix the latches 2061. When it is necessary to disassemble the vertical plate 202, the user needs to press the unlocking section 2063 from right to left through the first slot 2042 and the second slot 2051 to move the entire spring 206, thereby disengaging the latches 2061 from the first rivet 301 and the second rivet 302, contacting the limit, and finally allowing the vertical plate 202 to slide relative to it.

[0046] refer to Figure 5The chassis 1000 is also equipped with a stand 400, and the stand 400 is equipped with a limiting post 401. The first connecting piece 204 includes a bent part 2043 and a vertical part 2044 that are connected to each other. The vertical part 2044 is fixedly connected to the second connecting piece 205 through a fastener 207. The bent part 2043 abuts against the end of the second connecting piece 205. The bent part 2043 is provided with a limiting hole 20431 corresponding to the limiting post 401. The limiting post 401 is engaged with the limiting buckle.

[0047] The upright frame 400 is provided with a limiting post 401, and the bent part 2043 is provided with a limiting hole 20431 corresponding to the limiting post 401. The limiting post 401 and the limiting hole 20431 are engaged and connected to each other to limit and fix the vertical plate 202 to a certain extent in case of horizontal shaking or displacement, thereby enhancing the stability of the vertical plate 202 within the chassis 1000.

[0048] On the other hand, the bent portion 2043 and the vertical portion 2044 are connected to each other. The vertical portion 2044 is fixedly connected to the second connecting piece 205. The bent portion 2043 abuts against the end of the second connecting piece 205 at a preset angle with the vertical portion 2044, thereby closing one end of the vertical plate 202, ensuring a stable connection between the first connecting piece 204 and the second connecting piece 205, thereby enhancing the structural strength of the vertical plate 202 to a certain extent and improving the stability of the chassis 1000 structure.

[0049] The limiting hole 20431 corresponds to and engages with the limiting post 401, which can achieve precise positioning and alignment, ensure that each component is in the correct position, avoid assembly errors, and improve the assembly accuracy of the vertical plate 202.

[0050] Specifically, the above design allows for easy assembly and disassembly of the vertical plate 202 and the chassis 1000, simplifying the operation steps and improving the efficiency of assembly and maintenance.

[0051] refer to Figure 5 The upright 400 is also provided with an outward push spring 206, which has a relief groove 4021 for avoiding the limiting post 401. The outward push spring 206 bends toward the side of the vertical plate 202 and can abut against the bending part 2043.

[0052] An outward-pushing spring 206 is provided on the upright frame 400, and the outward-pushing spring 206 bends toward the side of the vertical plate 202. Therefore, the outward-pushing spring 206 abuts against the bent part 2043 of the vertical plate 202, so that the elastic force generated by its own elastic deformation forces the vertical plate 202 to move toward the side of the opening 101. Together with the first rivet 301 provided on the housing 100 and the second rivet 302 provided on the horizontal plate 201, the spring 206 on the vertical plate 202 is limited and fixed. The elastic force of the outward-pushing spring 206 makes the buckle 2061 on the spring 206 abut and clamp with the first rivet 301 and the second rivet 302 respectively, thereby ensuring the limiting and fixing effect of the vertical plate 202, preventing the vertical plate 202 from sliding or loosening in the chassis 1000, and making the overall structure of the chassis 1000 more stable and solid.

[0053] The outward push spring 206 bends toward the side of the vertical plate 202 and can abut against the bending part 2043 to ensure that the outward push spring 206 can apply elastic force to the bending part 2043 to limit and fix the vertical plate 202, thereby enhancing the stability of the internal components of the chassis 1000 and preventing loosening or displacement.

[0054] refer to Figure 2 The housing 100 has multiple slots 102 for placing functional sub-cards. The partition assembly 200 is located at the partition of some of the slots 102, and the partitions of the remaining slots 102 are provided with ear plates 2011.

[0055] Multiple slots 102 can be used to house multiple functional daughter cards, thus providing the chassis 1000 with greater expandability and flexibility to meet different needs. Partition assemblies 200 are located at the partitions of some slots 102 to isolate the functional daughter cards. This arrangement can limit and fix the functional daughter cards to a certain extent. At the same time, it can prevent interference and mutual influence between functional daughter cards, improving the stability and performance of the chassis 1000.

[0056] On the other hand, the ear plate 2011 is set at the separation of the other slots 102 except for the partition assembly 200. The ear plate 2011 can play a role in separation and support, and can firmly fix each functional sub-card, preventing it from shaking or loosening during transportation or use, thereby improving the overall stability and reliability of the chassis 1000.

[0057] It is easy to understand that the partition assembly 200 and the ear plate 2011 can work together to effectively divide and utilize the internal space of the chassis 1000, and the internal space can be freely combined as needed to place functional daughter cards of different models and sizes.

[0058] refer to Figure 3The first connecting piece 204 is provided with a first vent 2045, and the second connecting piece 205 is provided with a second vent 2052 corresponding to the first vent 2045.

[0059] The first connecting piece 204 has a first ventilation opening 2045, and the second connecting piece 205 has a second ventilation opening 2052 corresponding to the first ventilation opening 2045. The first ventilation opening 2045 and the second ventilation opening 2052 cooperate to form a structure that can be used for heat dissipation and ventilation. When the function daughter card is inserted into the chassis 1000, it enhances the heat dissipation and ventilation effect inside the chassis 1000 to ensure the normal use of the function daughter card. The above configuration can enhance the air circulation and heat dissipation inside the chassis 1000, effectively reduce the internal temperature of the chassis 1000, and improve the stability and reliability of the chassis 1000.

[0060] Specifically, the design of the first vent 2045 and the second vent 2052 allows air to flow evenly inside the vertical plate 202, avoiding excessively high or low local temperatures and ensuring temperature balance inside the chassis 1000 and in various areas of the functional daughter cards, which is beneficial to the long-term stable operation of the chassis 1000.

[0061] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
