[0030] With the rapid development of science and technology, electronic devices have become an indispensable tool in people's daily life. In existing electronic devices, the fixing structure for fixing the mainboard on the shell base occupies the design space of the electronic components of the mainboard, bringing many limitations and inconvenience to the design of the mainboard.

[0031] The following will be described in detail Figures 1-10 The electronic device 100 according to the embodiments of the disclosure will be described in detail.

[0032] It should be noted that in the exemplary embodiments shown, in order to describe the direction, a coordinate system of a first direction X, a second direction Y, and a third direction Z is constructed, and any two of the first direction X, the second direction Y, and the third direction Z intersect, for example, any two of the first direction X, the second direction Y, and the third direction Z are perpendicular. For example, the first direction X can correspond to the length direction of the electronic device, the second direction Y can correspond to the width direction of the electronic device, and the third direction Z can correspond to the thickness direction of the electronic device, but this is only an exemplary description and should not be understood as a limitation on the direction. It should be understood that the first direction X, the second direction Y, and the third direction Z can change as the morphology or use state of the electronic device changes.

[0033] As shown in FIG. 1, the electronic device 100 includes a mainboard 110, a shell 120, and a fixing structure 130. Figure 1 And Figure 2As shown, the electronic device 100 according to the embodiment of the present disclosure can include a mainboard 1, a base 2 and a tray 3.

[0034] Specifically, with reference to the combination of Figure 1 and Figure 2 , the mainboard 1 can have a target surface 11; the base 2 can have a first fixing part 21; the tray 3 can be connected with the mainboard 1, and the tray 3 can be provided with a second fixing part 31 away from the target surface 11; the second fixing part 31 can be adaptively connected with the first fixing part 21 to form a target space with the target surface 11.

[0035] Exemplarily, the electronic device 100 can be a server, a host, a notebook computer, a mobile phone, a tablet computer, a smart wearable device, etc. However, the embodiments of the present disclosure are not limited thereto, i.e., a person skilled in the art can adjust or set according to specific needs.

[0036] Taking the electronic device as a server, the server can be used to provide computing, storage or network services, and the mainboard 1, the base 2 and the tray 3 in the present disclosure can be structural members constituting the server.

[0037] Exemplarily, the mainboard 1 can include a core circuit board of the electronic device, and can integrate a processor unit, a memory unit and a power management unit, etc. In some examples, the integrated processor unit, memory unit and power management unit, etc. can be arranged on the other side opposite to the target surface 11, and the electronic elements (such as pins) of the processor unit, memory unit and power management unit, etc. can pass through the mainboard 1 and extend from the target surface 11 of the mainboard 1, the target surface 11 can include a surface of the mainboard for accommodating the electronic elements (such as pins), and can provide a reference plane for the formation of the subsequent target space, and the geometric parameters such as flatness and surface roughness of the target surface 11 can be adaptively designed according to the performance requirements of the electronic device, for example, if the installation of a high-precision connector is required, the flatness of the target surface 11 can be controlled within ±0.05mm.

[0038] Exemplarily, the base 2 can include a structural component of an external contour, used to accommodate internal components and provide a support basis for the mainboard and the tray, and can have certain mechanical strength and protection function. For example, the base 2 can include the bottom of the shell of the host, which can be made of engineering plastic or aluminum alloy. However, the embodiments of the present disclosure are not limited thereto, i.e., a person skilled in the art can adjust or set according to specific needs.

[0039] Exemplarily, the tray 3 can include a connecting structure for connecting the mainboard 1 to the base 2, and the tray 3 can have certain mechanical strength and can be made of engineering plastic, magnesium alloy or aluminum alloy. One of the ways in which the tray 3 connects the mainboard 1 to the base 2 can include that one side of the tray 3 is connected with the mainboard 1 and the other side of the tray 3 is connected with the base 2.

[0040] Exemplarily, when assembling or connecting each component, the tray 3 can be pre-connected with the main plate 1, so that the tray 3 forms a predetermined spatial posture relative to the target surface 11 of the main plate 1, and then the second fixing part 31 of the tray 3 is adaptively connected with the first fixing part 21 of the base 2. After the second fixing part 31 and the first fixing part 21 are completely matched, the target surface 11 of the main plate 1, the corresponding supporting surface of the base 2 and the corresponding surface of the tray 3 jointly form a closed or semi-closed target space. The role of the target space can include but is not limited to providing a mounting space for electronic components, constructing an electromagnetic shielding environment, planning a heat dissipation channel, etc., and the specific functions can be designed in combination with the application scenarios of electronic devices.

[0041] Exemplarily, the connection mode of the tray 3 and the main plate 1 can include bonding, and can also include connection through a connecting piece, and the connection mode of the tray 3 and the main plate 1 is not limited here.

[0042] Exemplarily, the surface where the main plate 1 and the tray 3 are connected can be the plane where the target surface 11 of the main plate 1 is located. The part where the main plate 1 and the tray 3 are connected protrudes from the target surface, so that a larger space can be formed between the target surface 11 and the tray 3, thereby facilitating the arrangement of electronic components (such as pins) between the target surface 11 and the tray 3.

[0043] Exemplarily, the connection of the tray 3 and the base 2 is achieved by matching the second fixing part 31 and the first fixing part 21. The second fixing part 31 is a connecting structure arranged on the tray 3, and the first fixing part 21 is a connecting structure arranged on the base 2. For example, the second fixing part 31 and the first fixing part 21 can be buckles to each other. For example, the second fixing part 31 and the first fixing part 21 can be plug-in structures, and the matching mode between the second fixing part 31 and the first fixing part 21 is only exemplified here and cannot be understood as a limitation of the present disclosure. In addition to the above examples, those skilled in the art can adjust or set according to specific needs.

[0044] Exemplarily, one of the connection modes of the tray 3 and the base 2 can include that the second fixing part 31 of the tray 3 is plugged into the first fixing part 21 of the base 2. After the second fixing part 31 and the first fixing part 21 are plugged in, the first fixing part 21 is located on the side of the second fixing part 31 close to the target surface 11. Based on this, the components forming the target space with the target surface 11 include the tray 3 and the first fixing part 21 located on the side of the second fixing part 31 close to the target surface.

[0045] Exemplarily, the second fixing part 31 is arranged to be away from the target surface 11, so that after the first fixing part 21 cooperates with the second fixing part 31, the second fixing part 31 can give more space to the first fixing part 21, so that the first fixing part 21 is also away from the target surface 11, thereby making the target surface 11 form a larger target space, and more electronic elements (for example, pins) can be arranged on the target surface 11, or electronic elements with a larger volume can be arranged.

[0046] In the electronic device 100 according to the embodiment of the present disclosure, the tray 3 and the base 2 can be connected together through the adaptive connection of the second fixing part 31 of the tray 3 and the first fixing part 21 of the base 2, and since the tray 3 is connected to the mainboard 1, the mainboard 1 can be connected to the base 2, and based on this, the overall structure of the electronic device 100 is complete, and the basic functions of the electronic device 100 can be realized. The target surface 11 of the mainboard 1 according to the embodiment of the present disclosure can be used to arrange electronic elements, and since the second fixing part 31 is away from the target surface 11, compared with the case where the second fixing part 31 is not treated to be away from the target surface 11, after the first fixing part 21 cooperates with the second fixing part 31, the target surface 11 can form a larger target space, thereby reserving more space for the design of electronic elements, and thus the design convenience of the electronic elements of the mainboard 1 can be improved.

[0047] According to some embodiments of the present disclosure, as Figures 3-6 shown, the second fixing part 31 is slidably connected to the first fixing part 21. As Figure 6 shown, the second fixing part 31 can be in a first position K1 relative to the first fixing part 21, and the tray 3 can be in a first connection state relative to the base 2. In the first position K1 or the first connection state, the mating surface of the second fixing part 31 and the first fixing part 21 can be attached, and the two are relatively fixed through the limiting of the mechanical structure, limiting the free sliding of the tray 3 in the first direction X. As Figure 5 shown, the second fixing part 31 can be in a second position K2 relative to the first fixing part 21, and the tray 3 can be in a second connection state relative to the base 2. In the second position K2 or the second connection state, the second fixing part 31 can partially or completely separate from the limiting structure of the first fixing part 21, so that the tray 3 can freely slide relative to the base 2 in the first direction X.

[0048] In some examples, as Figure 6 shown, the first connection state can be a fixed state of the tray 3 and the base 2, and as Figure 5As shown, the second connection state can be the separated state of the tray 3 and the base 2. The second fixing part 31 can move from the second position K2 to the first position K1 relative to the first fixing part 21 to insert the second fixing part 31 into the first fixing part 21, thereby realizing the switch from the separated state to the fixed state between the tray 3 and the base 2. For example, the second fixing part 31 moves from the second position K2 to the first position K1 along the first direction X, and the structural features of the second fixing part 31 (such as protrusions, guide rails, locking tongues, etc.) can gradually engage with the matching structure of the first fixing part 21 (such as grooves, tracks, lock holes, etc.). Through the guiding and positioning design during the sliding process (such as inclined guides, chamfer alignment), the second fixing part 31 can be smoothly inserted into the first fixing part 21 to complete the mechanical limiting, so that the tray 3 and the base 2 are locked in a fixed state.

[0049] like Figure 5 and Figure 6 As shown, the second fixing part 31 can move from the first position K1 to the second position K2 relative to the first fixing part 21 to remove the second fixing part 31 from the first fixing part 21, thereby switching the tray 3 and the base 2 from a fixed state to a separated state. For example, an external force (e.g., pushing the tray 3 in the opposite direction X) can be applied to move the second fixing part 31 from the first position K1 to the second position K2 along the first direction X. The structural features of the second fixing part 31 (e.g., protrusions, guide rails, locking tongues, etc.) can gradually disengage from the matching structure of the first fixing part 21 (e.g., grooves, tracks, lock holes, etc.). The second fixing part 31 can be removed from the first fixing part 21, and the constraint between the tray 3 and the base 2 is released, thereby switching to the separated state.

[0050] In other words, in the embodiments disclosed herein, the second fixing part 31 is slidably and removably connected to the first fixing part 21, which enables the installation and disassembly of the tray 3 and the base 2. That is, the second fixing part 31 is slidably and removably connected to the first fixing part 21, which facilitates the installation and disassembly of the tray 3 relative to the base 2.

[0051] For example, the first fixing part 21 and the second fixing part 31 may include specific geometric contours to achieve a fit between them. For instance, the first fixing part 21 may include a groove structure, and the second fixing part 31 may include a matching protrusion structure. The cross-sectional shapes of the groove structure and the protrusion structure may match, and the matching shape may include at least one of T-shaped, dovetail-shaped, and rectangular shapes to achieve stability during the sliding process, while providing sufficient mechanical strength to withstand vibrations and impacts during device operation (e.g., connection reliability in electronic device drop test scenarios).

[0052] Exemplarily, the fitting tolerance of the first fixing part 21 and the second fixing part 31 can be designed to ensure the smoothness of sliding and the stability after connection. For example, the fitting gap of the first fixing part 21 and the second fixing part 31 can meet the smooth sliding requirement, for example, the fitting gap of the first fixing part 21 and the second fixing part 31 can be 0.05-0.2mm, to balance the sliding resistance and positioning accuracy.

[0053] Exemplarily, in the locking stage, that is, when the second fixing part 31 is in the first position K1, the pre-tightening force can be achieved by interference fit, elastic deformation (such as elastic engagement of a plastic buckle, extrusion of a metal spring, etc.), and the like, to ensure that the first fixing part 21 and the second fixing part 31 are not loose after connection, and to avoid separation of the tray and the base due to vibration during operation of the electronic device, affecting the stability of the electronic components.

[0054] In the embodiments of the present disclosure, without the help of complex tools or multi-step operations, the insertion locking of the second fixing part 31 and the first fixing part 21 (from the second position K2 to the first position K1) can be completed by sliding the tray 3 in the first direction X, which can improve the assembly efficiency compared with the traditional screw locking, glue bonding and the like. When it is necessary to replace the tray 3 (such as upgrading internal modules, repairing faulty components, etc.), it is only necessary to slide and separate in the reverse direction (from the first position K1 to the second position K2) to disassemble, without the need to disassemble the base 2 or other related components, which can reduce the operation and maintenance cost, and is especially suitable for modularly designed electronic devices, such as electronic devices with replaceable battery trays and expansion interface modules.

[0055] According to some embodiments of the present disclosure, as shown in Figure 1 and Figure 2 The tray 3 can have a tray frame 32, and the tray frame 32 and the target surface 11 can form a first space S1 of the target space. The tray frame 32 can be connected with a plurality of second fixing parts 31. The tray frame 32 and the target surface 11 have a first height H1, and the second fixing part 31 and the target surface 11 have a second height H2, and the first height H1 can be less than the second height H2.

[0056] Exemplarily, as shown in Figure 1 The tray frame 32 can include the main support structure of the tray, be used for connecting with the main board, and be used for arranging the second fixing part 31. In the case where the second fixing part 31 cooperates with the first fixing part 21, the component between the target surface and the tray frame 32 forms the target space, which can be defined as the first space S1, that is, the target space at least includes the first space S1.

[0057] Exemplarily, in combination with Figure 1And Figure 2 The first height H1 between the tray holder 32 and the target surface 11 can be the interval distance between the tray holder 32 and the target surface 11 in the third direction Z, and the second height H2 between the second fixing part 31 and the target surface 11 can be the interval distance between the second fixing part 31 and the target surface 11 in the third direction Z. For example, the first height H1 can be the interval distance between the target surface 11 of the mainboard 1 and the reference surface of the tray holder 32 in the third direction Z, and the second height H2 can be the interval distance between the target surface 11 of the mainboard 1 and the reference surface of the second fixing part 31 in the third direction Z. The first height H1 and the second height H2 can be designed according to the height of the electronic components (for example, the height of the chip package) to ensure that there is enough gap after the electronic components are assembled to avoid interference, while meeting the needs of heat dissipation, electromagnetic compatibility, etc.

[0058] In some exemplary embodiments of the present disclosure, the tray holder 32 and the base 2 can be connected through a plurality of second fixing parts 31 and a plurality of first fixing parts 21, and the structure strength and stability after assembly can be improved through multiple fixing points.

[0059] Exemplarily, as shown in Figure 2 , the first fixing part 21 and the second fixing part 31 can be multiple, and the multiple first fixing parts 21 and the multiple second fixing parts 31 can make the tray holder 32 have multiple fixing points when fixed with the base 2, thereby increasing the fixing strength and stability.

[0060] As shown in Figure 2 , the second fixing part 31 is provided as a plurality of independent structures and is arranged at intervals along the circumferential direction of the tray holder 32. It should be noted that the "circumferential direction" here can mean the contour direction around the fitting area of the tray holder 32 and the base 2, for example, fitting the edge of the mounting groove on the base 2, the periphery of the functional area of the tray holder 32, so that the multiple second fixing parts 31 can be connected with the first fixing part 21 of the base 2 from different spatial orientations. For example, the fitting area of the tray holder 32 and the base 2 can be a rectangular groove, and the multiple second fixing parts 31 can be arranged at both ends of the long side and the middle of the short side of the rectangular groove, or symmetrically distributed, for example, symmetrically distributed two by two in the first direction X and the second direction Y.

[0061] In addition to the circumferentially spaced arrangement, in some other exemplary embodiments of the present disclosure, the arrangement positions of the plurality of second fixing portions 31 can be flexibly adjusted according to requirements. For example, the plurality of second fixing portions 31 can be arranged radially concentratedly, and the cooperation region of the tray holder 32 and the base 2 can be a circular or annular structure, and the second fixing portions 31 can be distributed along the radial direction of the circular or annular structure to adapt to the connection requirements of rotation locking and the like. In combination with the functional modules (for example, the heat-emitting area carrying chips, the interface area connecting high-frequency signals, and the like) on the tray holder 32, the second fixing portions 31 can be arranged at the periphery of the functional area to strengthen the stability of the functional area through structural connection, for example, to reduce the influence of thermal expansion and contraction caused by heat emission on the connection. The plurality of second fixing portions 31 can be arranged equidistantly or non-equidistantly, for example, the spacing between the plurality of second fixing portions 31 can be adjusted according to the mechanical simulation results of the base 2, and the second fixing portions 31 can be arranged densely in the area with large stress and sparsely in the area with small stress to optimize the material utilization rate and the connection reliability.

[0062] When the tray holder 32 is fixed to the base 2, the plurality of second fixing portions 31 can be cooperated with the plurality of first fixing portions 21 of the base 2 synchronously to form multi-fixing-point cooperation. Compared with single-point stress of single fixing portion, multi-fixing-point can disperse the mechanical stress after assembly to multiple connection positions to avoid structural deformation and connection failure caused by local stress concentration, thereby the strength and stability of the overall connection can be improved.

[0063] Exemplarily, as shown in Figure 1 , the tray holder 32 has a first height H1 from the target surface 11, and the second fixing portion 31 has a second height H2 from the target surface 11, and the first height H1 between the tray holder 32 and the target surface 11 is set to be smaller than the second height H2 between the second fixing portion 31 and the target surface 11, which can facilitate the tray 3 to have the second fixing portion 31 away from the target surface 11.

[0064] According to some embodiments of the present disclosure, as shown in Figure 3 , the tray 3 can have a connecting portion 33, one end of the connecting portion 33 can be connected to the tray holder 32, the other end of the connecting portion 33 can be connected to the second fixing portion 31, and the other end of the connecting portion 33 can extend downwardly relative to the tray holder 32.

[0065] Exemplarily, as shown in Figure 3As shown, the connecting portion 33 can be a connecting structure connecting the tray holder 32 and the second fixing portion 31, and the tray holder 32 and the second fixing portion 31 are connected as a whole through the connecting portion 33. In some exemplary embodiments, the connecting portion 33, the tray holder 32 and the second fixing portion 31 can be an integrally formed structure. In other exemplary embodiments, the connecting portion 33, the tray holder 32 and the second fixing portion 31 can also be a split structure. For example, the connecting portion 33 and the tray holder 32 can be integrally formed, and the two are split from the second fixing portion 31, one of the split implementation manners can be that the connecting portion 33 and the second fixing portion 31 are connected through a connecting piece. For example, the connecting portion 33 and the second fixing portion 31 can be integrally formed, and the two are split from the tray holder 32, one of the split implementation manners can be that the connecting portion 33 and the tray holder 32 are connected through a connecting piece. For example, any two of the connecting portion 33, the tray holder 32 and the second fixing portion 31 can be split structures from each other, the connecting portion 33 and the second fixing portion 31 can be connected through a connecting piece, and the connecting portion 33 and the tray holder 32 can be connected through a connecting piece.

[0066] In some exemplary embodiments of the present disclosure, the other end of the connecting portion 33 extends downwardly relative to the tray holder 32, for example, the other end of the connecting portion 33 extends toward the obliquely downward direction of the direction away from the target surface 11 of the tray holder 32, for example, in the direction of the negative direction of the third direction Z and inclined relative to the first direction X and the second direction Y, and the inclination angle here can be designed according to the internal space requirement and structural strength requirement of the device, for example, can be selected within the range of 30°-60°, to balance the space utilization and structural stability. Through the oblique extension design of the connecting portion 33 described above, when the second fixing portion 31 is connected to the other end of the extended connecting portion 33, the distance (for example, H2) between the second fixing portion 31 and the target surface 11 can be greater than the distance (for example, H1) between the tray holder 32 and the target surface 11. That is, as shown in the figure, through the downwardly inclined extension of the connecting portion 33, the first height H1 between the tray holder 32 and the target surface 11 can be less than the second height H2 between the second fixing portion 31 and the target surface 11. Figure 3 As shown, through the downwardly inclined extension of the connecting portion 33, the first height H1 between the tray holder 32 and the target surface 11 can be less than the second height H2 between the second fixing portion 31 and the target surface 11.

[0067] Exemplarily, since the connecting portion 33 extends downwardly and obliquely, a space transition structure is formed between the tray holder 32 and the second fixing portion 31, and the second fixing portion 31 is arranged to sink downwardly away from the target surface 11. The target surface 11 is a reference plane, and the first height H1 between the tray holder 32 and the target surface 11 is determined by the basic space requirement of the electronic device. Through the downward and oblique design of the connecting portion 33, the second fixing portion 31 can obtain more sinking space, thereby meeting the specific space requirement when cooperating with the base and other components. This space layout design can effectively optimize the space utilization efficiency inside the electronic device. For example, when the first fixing portion 21 on the base has a specific height size or installation depth requirement, the space position of the second fixing portion 31 can be accurately controlled by adjusting the inclination angle and extension length of the connecting portion 33, so as to adapt between the first fixing portion 21, while avoiding space interference with other components around the tray holder 32, and ensuring the compactness and rationality of the internal structure of the electronic device. In addition, by means of the oblique extension form of the connecting portion 33, when bearing external force, the stress can be dispersed by using the geometric structure thereof. Compared with the vertical or horizontal extension connecting structure, the oblique extension connecting portion 33 can conduct and decompose the stress along the oblique direction, avoid stress concentration in the local area, thereby improving the structural stability and fatigue resistance of the entire tray 3 and even the electronic device, and effectively prolonging the service life of the product.

[0068] According to some embodiments of the present disclosure, as shown in Figure 3 The tray 3 can have a reinforcing portion 34, one end of the reinforcing portion 34 in the first direction X can be connected to the second fixing portion 31, the other end of the reinforcing portion 34 in the first direction X can be connected to the tray holder 32, and both ends (left and right ends in the first direction X) of the second fixing portion 31 can have a second clamping portion 311 protruding from the reinforcing portion 34 in the second direction Y.

[0069] Exemplarily, as shown in Figure 3 The reinforcing portion 34 can be a structure for reinforcing the strength of the tray 3. For example, the reinforcing portion 34 can reinforce the strength of the second fixing portion 31 by connecting and fixing one end of the second fixing portion 31 connected to the reinforcing portion 34 through the reinforcing portion 34, so that the connection between the second fixing portion 31 and the bottom plate 22 is more stable. For another example, when the second fixing portion 31 is connected to the base, it can bear external forces such as plugging force and vibration load. The reinforcing portion 34, as a rigid connecting bridge between the second fixing portion 31 and the tray holder 32, can disperse the external force borne by the second fixing portion 31 to the large-area structure of the tray holder 32, so as to avoid deformation or fracture of the second fixing portion 31 due to excessive local stress.

[0070] Exemplarily, the second clamping portion 311 can include a structural member connected to the first fixing portion 21.

[0071] Exemplarily, in the case of setting the reinforcing portion 34, the second clamping portion 311 protrudes from the reinforcing portion 34 along the second direction Y, and the protruding portion can be matched with the first fixing portion 21, so as to realize the matched connection of the second fixing portion 31 and the first fixing portion 21. The size of the second clamping portion 311 protruding from the reinforcing portion 34 along the second direction Y can be any size at which the second clamping portion 311 can be engaged with the first fixing portion 21. Here, the specific value of the size of the second clamping portion 311 protruding from the reinforcing portion 34 along the second direction Y is not limited too much.

[0072] For example, the second clamping portion 311 can include structures such as protrusions, hooks, clamping teeth, etc. The protruding second clamping portion 311 can be matched with the recessed structure of the first fixing portion 21 to realize physical connection. The size of the second clamping portion 311 protruding from the reinforcing portion 34 along the second direction Y can satisfy the balance between connection reliability and assembly feasibility. The protruding size of the second clamping portion 311 protruding from the reinforcing portion 34 along the second direction Y needs to ensure the “effective engagement depth” with the first fixing portion 21. If the size is too small, the clamping portion may be caused to come out due to vibration or impact. If the size is too large, the assembly resistance will be increased, and even the structure of the first fixing portion 21 may be damaged. In some exemplary embodiments, the protruding size of the second clamping portion 311 protruding from the reinforcing portion 34 along the second direction Y can be in the range of 0.5 mm-3 mm.

[0073] In the embodiments of the present disclosure, the connection of the reinforcing portion 34 along the first direction X and the protruding connection of the second clamping portion 311 along the second direction Y can form a bidirectional constraint in the X-Y plane, that is, to limit the sliding of the tray 3 in the first direction X and the second direction Y. Compared with a single-direction connection structure, the stability of the connection can be improved.

[0074] According to some embodiments of the present disclosure, as shown in Figure 2 and Figure 4 The base 2 can have a bottom plate 22, and the bottom plate 22 can be connected with the plurality of second fixing portions 31. The bottom plate 22 can be provided with a first accommodating portion 221 and a second accommodating portion 222. The first accommodating portion 221 can be correspondingly arranged with the first fixing portion 21, for example, the corresponding arrangement can be understood as that the first accommodating portion 221 and the first fixing portion 21 are arranged in a straight line in the second direction Y. As shown in Figure 5 and Figure 6 The bottom plate 22 can be connected with the tray holder 32 and located below the tray holder 32. The first fixing portion 21 can be connected with the second fixing portion 31 and located above the second fixing portion 31. The first fixing portion 21 and the target surface 11 can form a second space S2 of the target space. The second space S2 can be arranged adjacent to the first space S1.

[0075] Exemplarily, the bottom plate 22 can be a main support structure of the base, used to accommodate internal components, provide a support base for the main board and the tray, and can have a certain mechanical strength and protection function. For example, the bottom plate 22 can be the bottom of the shell of the mainframe, which can be made of engineering plastic or aluminum alloy. However, embodiments of the present disclosure are not limited thereto, and can be adjusted or set according to specific needs.

[0076] Exemplarily, as shown in Figure 1 , the components forming the target space with the target surface 11 in the case of cooperation between the second fixing part 31 and the first fixing part 21 can include the tray holder 32 and the first fixing part 21 located on the side of the second fixing part close to the target surface. Here, the target space between the target surface and the first fixing part can be defined as the second space S2, that is, the target space can also include the second space S2.

[0077] Exemplarily, as shown in Figure 2 , the one-to-one connection between the plurality of first fixing parts 21 on the bottom plate 22 and the plurality of second fixing parts 31 can increase the fixing strength and stability of the bottom plate 22 and the tray 3.

[0078] Exemplarily, as shown in Figure 5 , the first accommodating part 221 can be an accommodating space corresponding to the first fixing part 21 opened on the bottom plate 22, and the first accommodating part 221 and the first fixing part 21 are linearly arranged in the second direction Y. As shown in Figure 4 and Figure 5 , the second accommodating part 222 can be an accommodating space opened on the bottom plate 22, and the second accommodating part 222 and the first accommodating part 221 can be arranged adjacent in the first direction X. Before the second fixing part 31 is inserted into the first fixing part 21 and after the second fixing part 31 is withdrawn from the first fixing part 21, the second fixing part 31 can be located in the second accommodating part 222. After the second fixing part 31 is inserted into the first fixing part 21, the first accommodating part 221 can provide a mounting space for the second fixing part 31.

[0079] Exemplarily, as shown in Figure 1 , the bottom plate 22 is connected to the tray holder 32 and located below the tray holder 32, which can facilitate the arrangement of the main board 1, the tray 3 and the bottom plate 22. The first fixing part 21 is connected to the second fixing part 31 and located above the second fixing part 31, which can facilitate the tight connection of the tray 3 and the bottom plate 22, and at the same time, due to the second fixing part 31 being away from the target surface 11, the second space S2 is larger, thereby reserving more space for the design of electronic components, thereby improving the design convenience of the electronic components of the main board 1.

[0080] According to some embodiments of the present disclosure, as shown in Figure 6As shown, when the tray 3 is in the first connection state relative to the base 2, the second fixing part 31 is located in the first accommodating part 221, and the second fixing part 31 is fixedly connected with the first fixing part 21; as shown Figure 5 As shown, when the tray 3 is in the second connection state relative to the base 2, the second fixing part 31 is located in the second accommodating part 222, and the second fixing part 31 is movably connected with the first fixing part 21.

[0081] In some examples, as shown Figure 6 As shown, the first connection state can include a fixed state between the second fixing part 31 and the first fixing part 21, in which the second fixing part 31 is fixedly connected with the first fixing part 21, and the fixed connection can be understood as that the second fixing part 31 and the first fixing part 21 can limit each other and be in a static state, as shown Figure 5 As shown, the second connection state can include a separation state of the second fixing part 31 and the first fixing part 21, in which the second fixing part 31 is movably connected with the first fixing part 21, and the movable connection can be understood as that the second fixing part 31 and the first fixing part 21 can move relative to each other. The second fixing part 31 moves from the second position K2 to the first position K1 relative to the first fixing part 21, which can realize the insertion of the second fixing part 31 into the first fixing part 21, so as to realize the switching of the tray 3 and the base 2 from the separation state to the fixed state, that is, the second fixing part 31 moves from the second accommodating part 222 to the first accommodating part 221, the second accommodating part 222 accommodates the second fixing part 31 which is not fixed with the first fixing part 21, and the first accommodating part 221 accommodates the second fixing part 31 which is fixed with the first fixing part 21. The second fixing part 31 moves from the first position K1 to the second position K2 relative to the first fixing part 21, which can realize the separation of the second fixing part 31 from the first fixing part 21, so as to realize the switching of the tray 3 and the base 2 from the fixed state to the separation state, that is, the second fixing part moves from the first accommodating part 221 to the second accommodating part 222, the first accommodating part 221 accommodates the second fixing part 31 which is fixed with the first fixing part 21, and the second accommodating part 222 accommodates the second fixing part 31 which is separated from the first fixing part 21.

[0082] It can be understood that the first accommodating part 221 can enable the bottom plate 22 to provide an adaptive environment for the fixation of the first fixing part 21 and the second fixing part 31, and the second accommodating part 222 can enable the bottom plate 22 to provide a moving environment for the second fixing part 31 before cooperating with the first fixing part 21, that is, through the second accommodating part 222 and the first accommodating part 221, it can be convenient for the second fixing part 31 to move from the second position K2 to the first position K1 on the bottom plate 22 relative to the first fixing part 21 to realize the insertion of the second fixing part 31 into the first fixing part 21, and it can be convenient to move from the first position K1 to the second position K2 to realize the separation of the second fixing part 31 from the first fixing part 21.

[0083] According to some embodiments of the present disclosure, as shown in Figure 4 The first fixing part 21 has first clamping parts 223 protruding from the bottom plate 22 towards the target surface 11, and a first accommodating part 221 is located between the two first clamping parts 223, and the first clamping part 223 has a guide surface 2231 near one end of the second accommodating part 222.

[0084] Exemplarily, the first clamping part 223 can include a structural member connected with the tray. The guide surface 2231 can include a slope suitable for guiding the second fixing part 31 into the first clamping part 223.

[0085] It can be understood that the first clamping part 223 can be connected with the second clamping part 311 in a plug-in manner to complete the cooperation and separation of the first fixing part 21 and the second fixing part 31, and the guide surface 2231 can facilitate the insertion and separation of the second clamping part 311 into the first clamping part 223.

[0086] For example, the first clamping part 223 can include a structural member protruding from the bottom plate 22 towards the target surface 11, for example, the first clamping part 223 can include an L-shaped cantilever structure. The at least two first clamping parts 223 can be symmetrically distributed on both sides of the first accommodating part 221 along the second direction Y. The first clamping part 223 can include a clamping jaw, a boss, a lock tongue, etc. Structure, which can cooperate with the second clamping part 311 of the tray 3 to achieve connection and limiting.

[0087] For example, the guide surface 2231 can include a slope structure, and the included angle between the guide surface 2231 and the bottom plate 22 can be 30°-60°. The guide surface 2231 can include a straight line type slope or a curved line type slope. By using the gradual size of the slope, the guide surface 2231 can provide a guiding and pre-positioning effect when the second clamping part 311 is inserted or separated, so as to reduce the assembly difficulty, and at the same time avoid the structure damage caused by hard impact.

[0088] Exemplarily, when the second clamping portion 311 of the tray 3 approaches the first fixed portion 21 along the first direction X, the front end of the second clamping portion 311 contacts the guide surface 2231. With the guiding effect of the inclined surface of the guide surface 2231, the second clamping portion 311 can be automatically aligned with the clamping area of the first clamping portion 223, and by continuously applying force, the second clamping portion 311 can be slid along the guide surface 2231 into the mating space between the first accommodating portion 221 and the first clamping portion 223, thereby completing the clamping locking. When it is necessary to disassemble the tray 3 and the base 2, the second clamping portion 311 can be slid out along the guide surface 2231. If the first clamping portion 223 is a resilient structure, the guide surface 2231 can assist the first clamping portion to elastically reset, avoiding the failure of the clamping structure due to frequent plugging and unplugging; if the first clamping portion 223 is a rigid structure, the guide surface 2231 can control the size of the separation force through the angle of the inclined surface, preventing damage to the components due to excessive force.

[0089] According to some embodiments of the present disclosure, the tray 3 can be connected with the base 2, the first fixed portion 21 can have a third height H3 from the target surface 11, the bottom plate 22 can have a fourth height H4 from the target surface 11, and the third height H3 can be not greater than the fourth height H4; or the tray frame 32 can have a first height H1 from the target surface 11, and the third height H3 can be not less than the first height H1.

[0090] In some examples, as shown in Figure 7 the third height H3 can be equal to the fourth height H4, in which case the surface of the first fixed portion 21 close to the target surface 11 can be flush with the surface of the bottom plate 22 close to the target surface 11. The first fixed portion 21 can not protrude from the bottom plate 22, so that the second space S2 formed by the first fixed portion 21 and the target surface 11 is larger, facilitating the design of electronic components on the mainboard 1.

[0091] In some examples, as shown in Figure 1 the third height H3 can be less than the fourth height H4, in which case the surface of the first fixed portion 21 close to the target surface 11 can protrude from the surface of the bottom plate 22 close to the target surface 11. The first fixed portion 21 can protrude from the bottom plate 22, and the second fixed portion 31 can be recessed away from the target surface 11, so that the protruding height of the first fixed portion 21 can be designed to be smaller, and the second space S2 formed by the first fixed portion 21 and the target surface 11 can also be larger, facilitating the design of electronic components on the mainboard 1.

[0092] In some examples, as shown in Figure 8As shown, the third height H3 can be equal to the first height H1, in which case the surface of the first fixing portion 21 close to the target surface 11 can be flush with the surface of the tray holder 32 close to the target surface 11. The first fixing portion 21 can not protrude from the tray holder 32, and thus the second space S2 formed between the first fixing portion 21 and the target surface 11 can be large, which is convenient for the design of electronic components on the main board 1.

[0093] In some examples, as shown in FIG. 2A, the third height H3 can be greater than the first height H1, in which case the surface of the first fixing portion 21 close to the target surface 11 can be flush with the surface of the bottom plate 22 close to the target surface 11. The second fixing portion 31 can be inserted into the side of the first fixing portion 21 away from the target surface 11. In this way, the first fixing portion 21 can not protrude from the tray holder 32, and thus the second space S2 formed between the first fixing portion 21 and the target surface 11 can be large, which is convenient for the design of electronic components on the main board 1. Figure 7 In some examples, as shown in FIG. 2B, the third height H3 can be greater than the first height H1, in which case the surface of the first fixing portion 21 close to the target surface 11 can be between the surface of the bottom plate 22 close to the target surface 11 and the surface of the tray holder 32 close to the target surface 11. The second fixing portion 31 can be inserted into the side of the first fixing portion 21 away from the target surface 11. In this way, the first fixing portion 21 can not protrude from the tray holder 32, and thus the second space S2 formed between the first fixing portion 21 and the target surface 11 can be large, which is convenient for the design of electronic components on the main board 1.

[0094] Figure 9 In some examples, as shown in FIG. 2B, the third height H3 can be greater than the first height H1, in which case the surface of the first fixing portion 21 close to the target surface 11 can be between the surface of the bottom plate 22 close to the target surface 11 and the surface of the tray holder 32 close to the target surface 11. The second fixing portion 31 can be inserted into the side of the first fixing portion 21 away from the target surface 11. In this way, the first fixing portion 21 can not protrude from the tray holder 32, and thus the second space S2 formed between the first fixing portion 21 and the target surface 11 can be large, which is convenient for the design of electronic components on the main board 1.

[0095] In some examples, the second fixing portion 31 inserted into the side of the first fixing portion 21 away from the target surface 11 can have two cases, as shown in FIG. 2C, one case is that the end of the second fixing portion 31 inserted into the first fixing portion 21 does not protrude from the bottom of the bottom plate 22, as shown in FIG. 2C, and the other case is that the end of the second fixing portion 31 inserted into the first fixing portion 21 protrudes from the bottom of the bottom plate 22, as shown in FIG. 2D. Figure 9 Figure 10 In some examples, the second fixing portion 31 inserted into the side of the first fixing portion 21 away from the target surface 11 can have two cases, as shown in FIG. 2C, one case is that the end of the second fixing portion 31 inserted into the first fixing portion 21 does not protrude from the bottom of the bottom plate 22, as shown in FIG. 2C, and the other case is that the end of the second fixing portion 31 inserted into the first fixing portion 21 protrudes from the bottom of the bottom plate 22, as shown in FIG. 2D.

[0096] According to some embodiments of the present disclosure, the second fixing portion 31 can include an elastic member. Exemplarily, the elastic member can be a structure with elasticity, and the second fixing portion 31 has elasticity, which can allow the second fixing portion 31 to have an elastic space, and when the second fixing portion 31 is inserted into and separated from the first fixing portion 21, elastic deformation can occur, which can make the process of inserting the second fixing portion 31 into the first fixing portion 21 easier, and also make the process of separating the second fixing portion 31 from the first fixing portion 21 easier.

[0097] ​​According to some embodiments of the present disclosure, the connecting portion 33 and the reinforcing portion 34 can each include an elastic member. Exemplarily, the elastic member can be a structure having elasticity in the third direction Z. Since the connecting portion 33 and the reinforcing portion 34 are respectively connected to the two ends of the second fixed portion 31 in the first direction X, the connecting portion 33 and the reinforcing portion 34 having elasticity in the third direction Z can make the second fixed portion 31 have a certain elastic space in the third direction Z. When the first fixed portion 21 is inserted and separated, elastic deformation can be generated, which can make the process of inserting the second fixed portion 31 into the first fixed portion 21 easier, and also make the process of separating the second fixed portion 31 from the first fixed portion 21 easier.
