[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Solid-state hard disks have fast reading and writing speeds, good shock resistance, light weight, and small size. They are an excellent data storage and transfer carrier. For ease of carrying, solid-state hard disks are often placed in hard disk cases. Hard disk cases generally include an inner body and an outer shell. The outer shell limits a housing cavity for placing the inner body. The inner body has a structure for carrying the solid-state hard disk and a structure for snapping with the outer shell. The inner body can be inserted into the housing cavity of the outer shell. In the prior art, in order to enhance the stability of the connection between the inner body and the outer shell, an auxiliary snap-in structure is often provided on the inner wall surface between the two ends of the outer shell. This makes it easy for the inner body to get stuck when being taken out of the housing cavity and installed, and the convenience of installing and removing the inner body is greatly reduced.

[0044] To solve the above technical problems, Figures 1 to 12 The present application proposes a box assembly 100 , which includes a shell 110 and a base 120 .

[0045] like Figure 1 , Figure 2 as well as Figure 3 As shown, the housing 110 defines a housing cavity 111, and the housing 110 is provided with a first opening 112 and a second opening 113 connected to the housing cavity 111, and the inner wall of the housing 110 adjacent to the first opening 112 is provided with a first clamping portion 114. It should be noted that the first clamping portion 114 is arranged at the inner wall of the housing 110 adjacent to the first opening 112, and the adjacent here refers to the distance from the first clamping portion 114 to the first opening 112 along the first direction X, and the distance from the first clamping portion 114 to the first opening 112 is not greater than the distance from the first clamping portion 114 to the second opening 113. The housing cavity 111 between the first opening 112 and the first clamping portion 114 is used to set the end of the base 120 for clamping with the housing 110, and the housing cavity 111 between the first clamping portion 114 and the second opening 113 is used to place the load to be carried. The larger distance from the first clamping end to the second opening 113 helps the box assembly 100 to carry larger items, thereby improving the carrying capacity of the box assembly 100.

[0046] like Figure 3 , Figure 8 as well as Fig.10As shown, the base 120 includes a carrying portion 121 for carrying articles. The base 120 is arranged in the accommodating cavity 111. The base 120 includes a first end 122 exposed at the first opening 112 and a second end 123 exposed at the second opening 113. The first end 122 is provided with a second clamping portion 124 clamped to the first clamping portion 114. Specifically, the carrying portion 121 of the base 120 can be any suitable component such as a clamping slot or a carrying platform. The first end 122 is exposed at the first opening 112, and the second end 123 is exposed at the second opening 113. Specifically, the first end 122 can be inserted into the first opening 112 and abut against the wall surface of the first opening 112 or the end surface of the housing 110. Similarly, the second opening 113 can be inserted into the second opening 113 and abut against the wall surface of the second opening 113 or the end surface of the housing 110.

[0047] Among them, Fig.10 as well as Fig.11 As shown, the direction from the first opening 112 to the second opening 113 is the first direction X, and the base 120 is configured so that when the second clamping portion 124 is separated from the first clamping portion 114, it can be separated from the housing 110 along the first direction X. Along the first direction X, the enclosed area of ​​the wall surface of the accommodating cavity 111 from the first clamping portion 114 to the second opening 113 gradually increases. Specifically, the base 120 can be inserted into the accommodating cavity 111 in the opposite direction of the first direction X. After the base 120 is inserted into the accommodating cavity 111, the first clamping portion 114 and the second clamping portion 124 are clamped, so that the base 120 is clamped to the housing 110. The first clamping portion 114 and the second clamping portion 124 are separated, and the base 120 can be taken out along the first direction X.

[0048] In the technical solution of the present application, the housing 110 is provided with a first opening 112 and a second opening 113 which are connected to the accommodating cavity 111. The inner wall of the housing 110 near the first opening 112 is provided with a first clamping portion 114. One side of the accommodating cavity 111 in the housing 110 is used for clamping with the base 120, and the other side is used for placing the bearing portion 121 of the base 120. The base 120 is configured so that the second clamping portion 124 can be separated from the housing 110 along the first direction X when it is separated from the first clamping portion 114. Along the first direction X, the enclosed area of ​​the wall surface of the accommodating cavity 111 from the first clamping portion 114 to the second opening 113 gradually increases. On the one hand, the base 120 is taken out of the second opening 113 and inserted into the accommodating cavity 111. The clamping structure of the housing 110 and the base 120 is arranged on the side close to the first opening 112, which effectively avoids the interference of the clamping structure on the taking and placing of the base 120. On the other hand, the base 120 is taken out from the second opening 113 along the first direction X, and the wall enclosed area of ​​the accommodating cavity 111 gradually increases from the first clamping portion 114 to the second opening 113. Along the first direction X, the removal space of the base 120 gradually increases, and the risk of the base 120 getting stuck when being taken out is greatly reduced. The base 120 is inserted into the accommodating cavity 111 in the reverse direction of the first direction X, and the wall enclosed area of ​​the accommodating cavity 111 gradually decreases from the second opening 113 to the first clamping portion 114. When the base 120 is installed, the wall of the accommodating cavity 111 can guide the insertion of the base 120, thereby improving the accuracy of the clamping between the first clamping portion 114 and the second clamping portion 124, and reducing the risk of the base 120 being stuck due to deviation from the clamping position.

[0049] The first clamping portion 114 can be configured as any suitable structure such as a clamping slot or a clamping buckle, and the second clamping portion 124 can also be configured as any suitable structure such as a clamping buckle or a clamping slot that is compatible with the first clamping portion 114. Figure 4As shown, in this embodiment, the first clamping portion 114 is configured as a card slot, and the second clamping portion 124 includes a clamping member 1241 and a first elastic member 1242. Along the direction perpendicular to the first direction X, one end of the first elastic member 1242 is connected to the clamping member 1241, and the other end is connected to the bearing portion 121. The end of the clamping member 1241 away from the first elastic member 1242 is inserted into the card slot. The shape of the card slot can be different according to different design requirements. Specifically, the card slot can be a wedge-shaped slot, a rectangular empty slot or an arc-shaped slot. The clamping member 1241 can be any structure that can be inserted into the card slot and abut against the wall of the card slot. The first elastic member 1242 can be any elastic component that meets the requirements, such as a spring, a spring sheet or rubber. It can be understood that, along the direction perpendicular to the first direction X, one end of the first elastic member 1242 is connected to the clamping member 1241, and the other end is connected to the bearing portion 121. When the base 120 is inserted into the accommodating cavity 111 from the second opening 113 along the opposite direction of the first direction X, the end of the clamping member 1241 away from the first elastic member 1242 abuts against the wall of the accommodating cavity 111. As the installation depth of the base 120 in the accommodating cavity 111 increases, the enclosed area of ​​the wall of the accommodating cavity 111 gradually decreases. The compression of the accommodating cavity 111 on the clamping member 1241 causes the clamping force of the clamping member 1241 on the first elastic member 1242 to gradually increase, and the first elastic member 1242 is continuously compressed. When the end of the base 120 is inserted into the first clamping portion 114, the first clamping portion 114 is configured as a clamping slot, and the clamping member 1241 is inserted into the clamping slot. The pressing force of the wall of the accommodating chamber 111 on the clamping member 1241 is reduced or released, and the degree of compression of the first elastic member 1242 is reduced or restored to its original state and can be clamped on the wall of the clamping slot, thereby making the second clamping portion 124 clamped on the first clamping portion 114. When taking out, the clamping member 1241 is separated from the clamping slot and the first elastic member 1242 is gradually released along the first direction X. The inner wall of the housing 110 guides the base 120, and the arrangement of the first elastic member 1242 and the clamping member 1241 makes the removal and installation of the base 120 more stable, and the risk of the base 120 getting stuck when taking out and placing is greatly reduced.

[0050] The base 120 is provided with a first end 122 of a second clamping portion 124 exposed in the first opening 112, and the clamping state of the first clamping portion 114 and the second clamping portion 124 can be controlled through the first opening 112. In order to improve the stability of the second clamping portion 124 being clamped in the clamping slot, as Figure 6 as well as Figure 7As shown, in this embodiment, along the direction perpendicular to the first direction X, the side of the first clamping portion 114 close to the first opening 112 has a first depth a, and the side of the first clamping portion 114 away from the first opening 112 has a second depth b, and the first depth a and the second depth b satisfy: a≤b. That is, the depth of the card slot close to the first opening 112 is less than the depth of the card slot away from the first opening 112. Specifically, the inner wall surface may include a first wall surface and a second wall surface, the first wall surface is perpendicular to the first direction X, the second wall surface intersects with the first wall surface, and the first wall surface and the second wall surface jointly limit the card slot. On the one hand, along the opposite direction of the first direction X, the depth of the card slot gradually decreases, and the second clamping portion 124 is clamped to the wall surface of the card slot. The reduction in the depth of the card slot helps to limit the further movement of the clamping member 1241 in the opposite direction of the first direction X, thereby improving the stability of the second clamping portion 124. On the other hand, along the first direction X, the first clamping portion 114 can be separated from the second clamping portion 124 in any suitable manner. Along the first direction X, the depth of the clamping groove gradually increases, and the space on the side close to the first wall is larger, which helps to separate the clamping component 1241 from the first wall and the second wall, further reducing the risk of the base 120 getting stuck.

[0051] When the base 120 enters the accommodating cavity 111 in the opposite direction of the first direction X and is taken out of the accommodating cavity 111 in the first direction X, there is a certain friction between the clamping member 1241 and the inner wall surface of the shell 110. In order to reduce the friction between the clamping member 1241 and the shell 110, in some embodiments, the end of the clamping member 1241 abutting against the shell 110 can be made of a material with low friction damping such as polytetrafluoroethylene. In some embodiments, the end of the clamping member 1241 abutting against the shell 110 can be provided with a ball. Figure 8 As shown, in this embodiment, the end of the clamping member 1241 away from the first elastic member 1242 has a first guide surface 1243, and the first guide surface 1243 intersects the first direction X. Specifically, the first guide surface 1243 can be set as an inclined surface or a curved surface, and the first guide surface 1243 can be only provided on the side of the clamping member 1241 close to the first opening 112, or can be provided on the side of the clamping member 1241 close to the second opening 113. The provision of the first guide surface 1243 can further improve the stability of the installation and removal of the base 120, and reduce the risk of the base 120 getting stuck.

[0052] The first clamping portion 114 and the second clamping portion 124 can be clamped and separated in any suitable form. In order to improve the convenience of separation of the first clamping portion 114 and the second clamping portion 124, in this embodiment, the base 120 also includes a pushing portion 125, and the pushing portion 125 has a second guide surface 1251, and the second guide surface 1251 intersects with the first direction X. The second guide surface 1251 is used to abut against the clamping member 1241, and the pushing portion 125 can move along the first direction X so that the clamping member 1241 presses the first elastic member 1242. Similarly, the second clamping portion 124 can also be provided with a third guide surface that cooperates with the pushing portion 125, and the third guide surface can be parallel to the second guide surface 1251, and the second guide surface 1251 can also directly abut against any suitable part on the second clamping portion 124. The second guide surface 1251 intersects with the first direction X, and the pushing portion 125 moves along the first direction X. The second guide surface 1251 can continuously press the clamping member 1241 toward the first elastic member 1242, and the first elastic member 1242 is compressed again. When the clamping member 1241 is pressed down by the pushing portion to be out of the clamping slot, the clamping restriction between the base 120 and the shell 110 is released, and the pushing portion 125 is continuously pushed along the first direction X. The pushing portion 125, the bearing portion 121, the clamping portion and the entire base 120 can be taken out from the accommodating cavity 111 along the first direction X. It can be understood that, in order to facilitate resetting, the pushing portion 125 can also be provided with an elastic member abutting against the bearing portion 121. When the external thrust on the pushing portion 125 disappears, the elastic member can restore the pushing portion 125 to the side away from the second clamping portion 124.

[0053] In order to improve the stability of the connection between the clamping member 1241, the pushing portion and the bearing portion 121, and the stability of the connection between the base 120 and the housing 110, the bearing portion 121 may be provided with a channel for guiding the movement of the pushing portion 125 and the clamping member 1241. Figure 8 as well as Fig. 9 As shown, in this embodiment, the bearing part 121 is provided with a first through hole 1211 and a second through hole 1212, the clamping member 1241 is penetrated in the first through hole 1211 along a direction perpendicular to the first direction X, the pushing part is penetrated in the second through hole 1212 along the first direction X and abuts against the clamping member, and a bearing position 1213 for carrying articles is provided on the side of the bearing part 121 away from the pushing part. When the clamping member 1241 moves in the opposite direction of the first direction X, the end of the clamping member 1241 away from the first elastic member 1242 is penetrated in the first through hole 1211, which helps to reduce the shaking of the clamping member 1241, thereby improving the accuracy of the docking of the clamping member 1241 with the slot. The second through hole 1212 guides the movement of the pushing part 125 along the first direction X, which can also reduce the risk of jamming caused by the position offset of the pushing part 125.

[0054] When the base 120 is installed in the accommodating cavity 111, different structures are arranged at the two ends of the base 120. In order to reduce the risk that the second end 123 of the base 120 is inserted into the first opening 112, thereby making the first clamping portion 114 unable to engage with the second clamping portion 124, or the base 120 cannot be removed after being inserted, the sizes of the first end 122, the second end 123, the first opening 112, and the second opening 113 can be set according to the need to prevent the first end 122 and the second end 123 from being misaligned with the first opening 112 and the second opening 113. Fig.12 As shown, specifically, the projection plane 130 is perpendicular to the first direction X. Along the first direction X, the first end 122 has a first projection 1221 on the projection plane 130, the second end 123 has a second projection 1231 on the projection plane 130, the first opening 112 has a third projection 1121 on the projection plane 130, and the second opening 113 has a fourth projection 1131 on the projection plane 130. It can be understood that the first projection 1221 is located in the fourth projection 1131, which means that the fourth projection 1131 covers the first projection 1221, and the area of ​​the first projection 1221 is smaller than the area of ​​the fourth projection 1131. The first end 122 and the second opening 113 have an assembly gap. Preferably, in some embodiments, the first end 122 and the wall surface of the second opening 113 have an assembly gap c, and the assembly gap c satisfies: c ≥ 0.2 mm. Other similar projection position relationships are not repeated here. Specifically, the assembly gap c can be any suitable value such as 0.2 mm, 0.3 mm or 0.5 mm. The assembly gap c refers to the distance between the first end 122 and the wall of the housing 110 at the second opening 113, and can also be understood as the boundary distance between the first projection 1221 and the fourth projection 1131. The setting of the assembly gap c enables the first end 122 to enter the container more accurately and stably, thereby improving the convenience of installing the base 120 and reducing the risk of jamming.

[0055] In some embodiments, the first projection 1221 is located within the fourth projection 1131, and the fourth projection 1131 is located within the second projection 1231. The first projection 1221 is located within the fourth projection 1131, that is, the first end 122 can be inserted into the accommodating cavity 111 from the second opening 113, and the fourth projection 1131 is located within the second projection 1231, that is, the first end 122 is passed through the second opening 113 to the accommodating cavity 111, and the second end 123 can be snapped to the end wall of the housing 110 provided with the second opening 113, and the second end 123 cannot enter the accommodating cavity 111 from the second opening 113. In some embodiments, the third projection 1121 is located within the second projection 1231, that is, the second end 123 cannot be snapped into the accommodating cavity 111 from the first opening 112. In some embodiments, the third projection 1121 is located within the first projection 1221, that is, the first end 122 cannot be inserted into the accommodating cavity 111 through the first opening 112. It should be noted that, in some embodiments, the first projection 1221 is located within the fourth projection 1131, and the fourth projection 1131 may also be equal to the second projection 1231, that is, the first end 122 can be inserted into the accommodating cavity 111 through the second opening 113, and the second end 123 can abut against the inner wall surface of the accommodating cavity 111 on the side of the housing 110 where the second opening 113 is provided. The different sizes of the first end 122, the second end 123, the first opening 112, and the second opening 113 help reduce the risk of the first end 122 and the second end 123 being mistakenly inserted into the first opening 112 and the second opening 113, reduce the risk of the base 120 being stuck, and improve the convenience of installing the base 120.

[0056] In order to further improve the stability of the clamping between the base 120 and the housing 110, the second end 123 may be provided with a component that abuts against the housing 110. Fig. 9 As shown, in this embodiment, the second end 123 is provided with a stopper 1232, and the stopper 1232 is used to abut against the wall surface of the side of the housing 110 where the second opening 113 is provided. The stopper 1232 can be configured as a protrusion or a buckle. In other words, the first end 122 of the base 120 is provided with a second clamping portion 124 clamped with the first clamping portion 114, and the second end 123 can directly abut against the housing 110. The abutment of the base 120 and the housing 110 at both ends makes the box assembly 100 more stable in structure. Whether it is moving or using, the first end 122 and the second end 123 are connected to the housing 110, which can effectively reduce the shaking of the base 120 in the accommodating cavity 111, thereby reducing the possibility of damage to the carried items, such as hard disks. In addition, the clamping of the base 120 and the housing 110 at both ends helps to prevent dust from entering the accommodating cavity 111, and improves the conduction and dissipation of heat on the carried items such as hard disks, so that the hard disk has a longer life.

[0057] In some embodiments, in order to further improve the convenience of installing the base 120, the first clamping portion 114 of the housing 110 may be provided with a plurality of clamping structures clamped with the second clamping portion 124, and the second clamping portion 124 may be clamped with a part of the structure of the first clamping portion 114. The base 120 may be configured as a rectangular parallelepiped, a cylindrical shape, or a cylinder with an elliptical cross section perpendicular to the first direction X. The first clamping portion 114 has a plurality of clamping positions, which enables the base to be inserted into the accommodating cavity 111 at any appropriate angle. Figure 5 as well as Figure 6 As shown, in some embodiments, the first clamping portion 114 includes a first clamping groove 1141 and a second clamping groove 1142. In a direction perpendicular to the first direction X, the second clamping groove 1142 is arranged opposite to the first clamping groove 1141, and the second clamping portion 124 can be inserted into the first clamping groove 1141 or the second clamping groove 1142. When in use, the clamping portion can be matched with the first clamping groove 1141 or the second clamping groove 1142, which greatly reduces the difficulty of the second clamping portion 124 matching with the first clamping portion 114, and the installation of the base 120 is more convenient. In some embodiments, the first clamping portion 114 is configured as a clamping groove arranged around an axis parallel to the first direction X. That is, the base 120 can be inserted into the accommodating cavity 111 by rotating around the circumference parallel to the first direction X at any appropriate angle. The setting of the annular clamping groove can also greatly reduce the difficulty of the second clamping portion 124 matching with the first clamping portion 114, making the installation of the base 120 more convenient. In order to improve the service life and user experience of the box assembly 100, the box assembly 100 may be provided with a colloid protective cover wrapped in the shell 110, which will not be described in detail here.
