[0046] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of this application, if the term "a plurality of" appears, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0047] In this application, unless otherwise clearly defined and limited, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited.

If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0050] Refer to Figure 1 , a box assembly provided by an embodiment of this application includes a first box body 100 and a second box body 200. Also refer to Figure 3, the first box body 100 and the second box body 200 are stacked along the first direction. The first box body 100 has a first side wall 110, and the second box body 200 has a second side wall 210. The first side wall 110 and the second side wall 210 are arranged along the second direction, wherein the first direction is perpendicular to the second direction. The seal 300 is located between the first side wall 110 and the second side wall 210, and the seal 300 is configured to be in a deformed state at the contact with the first side wall 110.

[0051] Continue to refer to Figure 3 , in the above embodiment, the seal 300 is located between the first side wall 110 and the second side wall 210, and is configured to be in a deformed state at the contact with the first side wall 110. Therefore, the seal 300 can be squeezed by the first side wall 110 and the second side wall 210 to play a sealing role, inhibiting external liquid from entering the interior of the box assembly through the gap between the first side wall 110 and the second side wall 210. Moreover, there is a frictional force between the deformed seal 300 and the first side wall 110 and the second side wall 210, and this frictional force can inhibit the two box bodies from separating from each other, thereby further ensuring good sealing performance.

[0052] Refer to Figure 2 , in some embodiments, the first direction is parallel to the depth direction of the box assembly, and the second direction is the length direction or the width direction of the box assembly.

[0053] Refer to Figure 2 , in some embodiments, the first direction is the assembly direction of the first box body 100. The seal 300 is configured to be in a state of deforming in the first direction and / or the second direction under the extrusion of the first side wall 110.

[0054] Specifically, in Figure 2 perspective, after the box assembly is completed, the first box body 100 is located above the second box body 200. During the assembly process, the first box body 100 gradually approaches the second box body 200 from top to bottom to complete the assembly. That is, the assembly direction (the first direction) of the first box body 100 is the direction from top to bottom.

[0055] Refer to Figure 3, after the assembly is completed, the seal 300 is squeezed by the first side wall 110 towards the second side wall 210 and is in a deformed state. In some embodiments, during the process of the first housing 100 being assembled in the first direction, the first side wall 110 will scrape the seal 300 in the first direction, causing the seal 300 to deform in the first direction, thereby inhibiting the first housing 100 from moving in the reverse direction along the first direction, that is, inhibiting the separation of the first housing 100 and the second housing 200 and ensuring a stable connection between the two. In some embodiments, after the first housing 100 is assembled, the distance between the first side wall 110 and the second side wall 210 is smaller than the dimension of the seal 300 in the second direction, thereby squeezing the seal 300 in the second direction and causing it to deform in the second direction, so as to form a good seal between the first side wall 110 and the second side wall 210. In Figure 3 In the illustrated embodiment, after the first housing 100 is assembled, the above two methods exist simultaneously, that is, the seal 300 has a deformation in the first direction and also has a deformation in the second direction.

[0056] Refer to Figure 3 , in some embodiments, the seal 300 includes a seal body 310 and a protrusion 320. The protrusion 320 protrudes from the seal body 310, and the seal body 310 is configured to be in a state of deforming in the first direction under the extrusion of the first side wall 110.

[0057] Continue to refer to Figure 3 , specifically, during the process of the first housing 100 being assembled in the first direction, the first side wall 110 will scrape the seal body 310 in the first direction, causing the seal body 310 to deform in the first direction. In this way, the frictional force between the seal body 310 and the first side wall 110 will inhibit the first housing 100 from moving in the reverse direction along the first direction, thereby inhibiting the separation of the first housing 100 and the second housing 200 and ensuring a stable connection between the two.

[0058] Refer to Figure 3 , in some embodiments, the seal 300 includes a seal body 310 and a protrusion 320. The protrusion 320 protrudes from the seal body 310, and the protrusion 320 is configured to be in a state of deforming in the first direction under the extrusion of the first side wall 110.

[0059] Continue to refer to Figure 3 , specifically, during the process of the first housing 100 being assembled in the first direction, the first side wall 110 will scrape the protrusion 320 in the first direction, causing the protrusion 320 to deform in the first direction. In this way, after the assembly is completed, the protrusion 320 can closely fit the first side wall 110, thereby forming a good seal between the first side wall 110 and the second side wall 210 and inhibiting liquid from entering the interior of the box assembly through this place.

[0060] Refer to Figure 4 , in some embodiments, the protrusion 320 has a connecting end 321 connected to the sealing body 310 and a free end 322 facing away from the sealing body 310. The free end 322 is bent in the first direction relative to the connecting end 321.

[0061] Continue to refer to Figure 4 , specifically, during the process of assembling the first box body 100 in the first direction, the first side wall 110 will scrape the protrusion 320 in the first direction, causing the free end 322 to deform and bend in the first direction relative to the connecting end 321. Thus, after the assembly is completed, the protrusion 320 is closely attached to the first side wall 110, forming a good seal between the first side wall 110 and the second side wall 210.

[0062] Refer to Figure 3 , in summary, during the assembly process, the deformation of the sealing body 310 in the first direction is mainly reflected in: it changes its own shape through elastic deformation, thereby suppressing the reverse movement of the first box body 100 in the first direction through the frictional force between it and the first side wall 110, and suppressing the separation of the first box body 100 and the second box body 200. The deformation of the protrusion 320 in the first direction is mainly reflected in: its free end 322 is bent in the first direction relative to the connecting end 321. Thus, after the assembly is completed, the protrusion 320 is closely attached to the first side wall 110, forming a good seal between the first side wall 110 and the second side wall 210.

[0063] Refer to Figure 3 , in some embodiments, the sealing body 310 is installed on the second side wall 210, and a protrusion 320 protrudes from the side of the sealing body 310 facing away from the second side wall 210.

[0064] Continue to refer to Figure 3 , specifically, during assembly, first fixedly install the sealing body 310 on the second side wall 210, and then gradually move the first box body 100 closer to the second box body 200 in the first direction to complete the assembly. During the assembly process, the first side wall 110 scrapes the sealing body 310 and the protrusion 320 in the first direction, causing both of them to deform in the first direction. In this way, the reverse movement of the first box body 100 in the first direction can be suppressed through the frictional force between the sealing body 310 and the first side wall 110, thereby suppressing the separation of the first box body 100 and the second box body 200 and achieving a stable connection between the two box bodies; at the same time, by closely attaching the protrusion 320 to the first side wall 110, a good seal is formed between the first side wall 110 and the second side wall 210, suppressing the entry of external liquid into the interior of the box assembly through this place.

[0065] Refer to Figure 4In some embodiments, the protrusion 320 is protruded from the sealing body 310 toward a third direction, and the third direction is set at an angle to the first direction.

[0066] Continue reading Figure 4 Specifically, the protrusion 320 protrudes along the third direction from the side of the sealing body 310 away from the second side wall 210. The angle between the first direction and the second direction is in the range of 0-180 degrees (including 0 degree and 180 degrees).

[0067] See also Figure 4 Preferably, in some embodiments, the protrusion 320 has a connecting end 321 connected to the sealing body 310, and a free end 322 facing away from the sealing body 310, the orthographic projection of the free end 322 on the second side wall 210 is the first end 323, the orthographic projection of the connecting end 321 on the second side wall 210 is the second end 324, the line connecting the first end 323 and the second end 324 is parallel to the first direction, and the direction in which the second end 324 points to the first end 323 is the first direction.

[0068] exist Figure 4 From the perspective, the direction from the second end 324 to the first end 323 is the direction from top to bottom, that is, the first direction. Figure 3 When the protrusion 320 is set to the above-mentioned inclined extension shape, when the first box body 100 is assembled along the first direction, the protruding direction of the protrusion 320 and the moving direction of the first side wall 110 are facing the same side. Therefore, the protrusion 320 will not hinder the movement of the first side wall 110, and the first box body 100 can be assembled more smoothly.

[0069] See also Figure 4 Preferably, in some embodiments, the side of the sealing body 310 facing away from the second side wall 210 is in a convex curved shape.

[0070] See also Figure 3 Specifically, the side of the sealing body 310 away from the second side wall 210 bulges toward the first side wall 110 to form a curved surface. In this way, the sealing body 310 can have a greater deformation ability when being squeezed by the first side wall 110, thereby further enhancing the sealing between the first side wall 110 and the second side wall 210.

[0071] See also Figure 4 In some embodiments, the sealing body 310 includes a first deformation portion 311 and a second deformation portion 312 which are sequentially arranged and connected along the first direction, and the protrusion 320 is connected to the junction of the first deformation portion 311 and the second deformation portion 312. Along the first direction, the size of the first deformation portion 311 protruding from the first side wall 110 gradually increases, and the size of the second deformation portion 312 protruding from the first side wall 110 gradually decreases.

[0072] Continue to refer to Figure 4 , specifically, the protrusion 320 protrudes along the third direction from the connection of the first deformation part 311 and the second deformation part 312. Figure 4 From a perspective, the dimension of the first deformation part 311 protruding from the first side wall 110 gradually increases from top to bottom, and the dimension of the second deformation part 312 protruding from the first side wall 110 gradually decreases from top to bottom. In this way, the side of the entire sealing body 310 facing away from the second side wall 210 can be in the shape of a smoothly changing curved surface, which is more convenient for manufacturing and less likely to break due to stress concentration.

[0073] Refer to Figure 4 , preferably, in some embodiments, the sealing body 310 includes a third end 313 and a fourth end 314 arranged in sequence along the first direction, and the distance between the connection of the first deformation part 311 and the second deformation part 312 and the third end 313 along the first direction is greater than the distance between the connection of the first deformation part 311 and the second deformation part 312 and the fourth end 314 along the first direction.

[0074] Continue to refer to Figure 4 , specifically, during the assembly process, the first side wall 110 scrapes the side of the first deformation part 311 and the protrusion 320 facing away from the second side wall 210 along the first direction, so as to inhibit the separation of the first box body 100 and the second box body 200 through the frictional force between the first deformation part 311 and the first side wall 110 after the assembly is completed, realizing a stable connection between the two box bodies; at the same time, a good seal is formed between the first side wall 110 and the second side wall 210 through the protrusion 320 closely fitting to the first side wall 110. In Figure 4 From a perspective, the connection of the first deformation part 311 and the second deformation part 312 is located below the midpoint of the entire sealing body 310 along the first direction. In this way, the dimension of the first deformation part 311 along the first direction can be larger, so that it can abut against the first side wall 110 more stably, and more stably inhibit the separation of the first box body 100 and the second box body 200 through the frictional force between the two.

[0075] Refer to Figure 4 , in other embodiments, it is also possible to directly set the side of the sealing body 310 facing away from the second side wall 210 as a hemispherical surface.

[0076] Refer to Figure 3 , in some embodiments, the second side wall 210 is recessed with a groove 211, and the sealing body 310 is embedded in the groove 211.

[0077] Continue to refer to Figure 3Specifically, a portion of the second side wall 210 is recessed toward the side away from the first side wall 110 to form a groove 211, and the size of the groove 211 is adapted to the sealing body 310 to achieve snap-on connection. During the manufacturing process, the sealing body 310 is embedded in the groove 211 to complete the fixed connection between the sealing body 310 and the second side wall 210. Preferably, a backing adhesive is provided on the side of the sealing body 310 away from the protrusion 320. When the sealing body 310 is embedded in the groove 211, it is also bonded to the groove 211 by the backing adhesive, thereby improving the firmness of the sealing member 300 fixed to the second side wall 210.

[0078] See also Figure 3 In some embodiments, the side of the sealing body 310 close to the second side wall 210 is flat. Correspondingly, the groove wall of the groove 211 is also flat. Such a configuration can facilitate processing and installation of the sealing member 300.

[0079] See also Figure 6 In some embodiments, the seal 300 is in the shape of a ring connected end to end. Correspondingly, the aforementioned groove 211 is also configured as a ring connected end to end for mounting the seal 300. When the seal 300 is configured in the above shape, it can form a full circle of sealing between the first side wall 110 and the second side wall 210, and better inhibit external liquid from entering the interior of the box assembly.

[0080] See also Figure 7 In some embodiments, the first box body 100 further has a third side wall 120. Figure 3 The third side wall 120 and the first side wall 110 are arranged at intervals along the second direction, and the second side wall 210 is inserted between the third side wall 120 and the second side wall 210 .

[0081] See also Figure 7 Specifically, the first box body 100 has a base plate 130. Figure 3 The first side wall 110 and the third side wall 120 extend from the substrate 130 in the first direction. The second side wall 210 is inserted between the third side wall 120 and the second side wall 210, so that during the assembly process, the third side wall 120 and the second side wall 210 guide and limit the second side wall 210, which helps to complete the assembly quickly and accurately.

[0082] See also Figure 9 In some embodiments, the second side wall 210 is provided with a blocking member 220 protruding toward the first side wall 110, and the blocking member 220 blocks the first side wall 110. When the first box body 100 is assembled along the first direction, the first side wall 110 will gradually approach the blocking member 220 until it is blocked by the blocking member 220, which indicates that the assembly has been completed, thereby limiting the assembly stroke and reminding the operator that the assembly has been completed.

[0083] Refer to Figure 1 Figure 1 , in some embodiments, the box assembly further includes a locking mechanism 400 for restraining the separation of the first box body 100 and the second box body 200. Thus, on the basis of restraining the separation of the two box bodies by friction as described above, the connection stability of the two box bodies can be further enhanced.

[0084] Refer to Figure 2 Figure 2 , in some embodiments, the locking mechanism 400 includes a hook 410 and a catch 420. One of the hook 410 and the catch 420 is arranged on the first box body 100, and the other is arranged on the second box body 200, and the hook 410 and the catch 420 are snap-connected.

[0085] Refer to simultaneously Figure 5 Figure 5 , specifically, the hook 410 is integrally connected with the first side wall 110, and the hook 410 has a certain elasticity. Refer to simultaneously Figure 6 Figure 6 , the catch 420 protrudes from the second side wall 210. Refer to Figure 5 Figure 5 , during the assembly process, the hook 410 deforms toward the side away from the catch 420 under the extrusion of the catch 420 until the catch 420 snaps into the slot 411 provided on the hook 410. In other embodiments, other types of snap-connection structures in the prior art may also be used. Alternatively, the snap-connection structure may be replaced with a magnetic attraction structure.

[0086] Refer to Figure 2 Figure 2 , in some embodiments, multiple groups of locking mechanisms 400 are symmetrically arranged on both sides of the first box body 100 and the second box body 200 along the second direction.

[0087] Specifically, Figure 2 Figure 2 in the illustrated embodiment, two groups of locking mechanisms 400 are provided, and these two groups of locking mechanisms 400 are symmetrically arranged on both sides of the first box body 100 and the second box body 200 along the second direction. Thus, the separation of the two box bodies can be better restrained. In other embodiments, more groups of locking mechanisms 400 may also be added. For example, more groups of locking mechanisms 400 are arranged at equal intervals in a circumferential circle of the first box body 100 and the second box body 200.

[0088] Refer to Figure 1 Figure 1 , in some embodiments, the depth of the second box body 200 along the first direction is greater than that of the first box body 100. Specifically, the first box body 100 is a box cover, and the second box body 200 is a box main body.
