[0035] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0036] The disclosed embodiment provides a housing clamping structure, including a hook assembly, a limit assembly and a clamping assembly. When in use, the hook assembly and the limit assembly are arranged on a first housing, and the clamping assembly is arranged on a second housing. When the first housing is connected to the second housing, the first housing is pressed toward the second housing, and the clamping assembly is respectively clamped with the hook assembly and the limit assembly, thereby achieving connection between the first housing and the second housing.

[0037] The structure of each component and the connection relationship between the components are described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 , Figures 2 to 4 As shown, the hook assembly 1 includes a rod body 11 and a hook head 12, one end of the rod body 11 is used to connect with the first shell 51, and the other end is connected with the hook head 12, and the hook head 12 includes two symmetrically arranged clamping protrusions 121; the limiting assembly 2 includes two limiting spring plates located on both sides of the rod body 11, and one end of the limiting spring plates is connected to the first shell 51; the locking assembly 3 includes two rollers 31, the two rollers 31 are used to be rotatably connected with the second shell 52, and the two rollers 31 are arranged at intervals along the radial direction, and the side ends of the rollers 31 are provided with clamping grooves 32 and limiting grooves 33 at intervals along the circumferential direction.

[0039] The rod body 11 is used to drive the hook head 12 to move between the first position and the second position. When the hook head 12 moves from the first position to the second position, the hook head 12 drives the roller 31 to rotate, and the hook head 12 is inserted between the two slots 32. The two slots 32 are respectively engaged with the engaging protrusions 121, and the two limiting slots 33 are respectively engaged with the limiting spring sheets.

[0040] That is, in the second position, under the action of the limiting spring piece, the roller 31 cannot continue to rotate, thereby limiting the roller 31, and the slot 32 on the roller 31 is engaged with the engaging protrusion 121, so that the hook head 12 and the rod body 11 cannot move relative to each other. The roller 31 limits the rod body 11, and the three limit each other, thereby achieving stable engagement of the shell engaging structure.

[0041] In the disclosed embodiment, the shell clamping structure also includes a limit block 4, which is used to connect to the second shell 52, and the limit block 4 includes a first limit surface 41 and a second limit surface 42; the side end of the roller 31 is concave, and the groove includes a third limit surface 34 and a fourth limit surface 35; when the hook head 12 is in the first position, the first limit surface 41 abuts against the third limit surface 34, and when the hook head 12 is in the second position, the second limit surface 42 abuts against the fourth limit surface 35.

[0042] The stopper 4 cooperates with the groove to limit the rotation angle of the roller 31, that is, the roller 31 rotates at a set rotation angle to switch between the first position and the second position. For example, when the hook head 12 moves from the first position to the second position, the hook head 12 drives the roller 31 to rotate at an angle of 30 to 40 degrees. At this rotation angle, the rod body 11 does not need to have an excessively long movement stroke, which is conducive to the ultra-thinness of the product.

[0043] For example, one end of the rod body 11 is fixedly connected to the first shell 51, wherein the driving force of the hook assembly 1 comes from the first shell 51, that is, when the first shell 51 and the second shell 52 are assembled, the first shell 51 and the second shell 52 are pressed together, which can synchronously drive the telescopic movement of the hook assembly 1.

[0044] For example, one end of the rod body 11 is an integral structure with the first housing 51. When the first housing 51 is produced, the hook assembly 1 is simultaneously manufactured and formed. This structure can improve the connection strength between the hook assembly 1 and the first housing 51, thereby improving the use strength of the housing clamping structure.

[0045] like Figure 3 As shown, for example, the limiting spring piece includes a connecting portion 21 and a spring piece portion 22 , one end of the spring piece portion 22 is connected to one end of the connecting portion 21 ; the connecting portion 21 is connected to the first shell 51 , and the other end of the spring piece portion 22 is used to engage with the limiting groove 33 .

[0046] The limiting spring piece has a certain deformation ability, wherein the deformation is achieved through the spring piece part 22. During the connection process between the hook assembly 1 and the locking assembly 3, the hook assembly 1 causes the spring piece part 22 to deform and lock with the limiting locking groove 32 in the deformed state. During the connection process, due to the deformation of the spring piece part 22, it has a certain rebound force. Driven by the rebound force, the hook assembly 1 is locked with the locking assembly 3.

[0047] For example, the limiting spring piece also includes an abutment portion 23, which is connected to the other end of the spring piece portion 22 and is parallel to the connecting portion 21. A protruding clamping portion 24 for clamping with the limiting groove 33 is provided at the connection between the abutment portion 23 and the spring piece portion 22; a side end of the roller 31 is provided with an abutment plane between the clamping groove 32 and the limiting groove 33. When the hook head 12 drives the roller 31 to rotate, the abutment plane rotates and drives the abutment portion 23 to displace, and the abutment portion 23 drives the spring piece portion 22 to deform. When the hook head 12 is clamped with the clamping groove 32, the spring piece portion 22 rebounds to make the clamping portion 24 abut against the limiting groove 33.

[0048] like Figure 4 and Figure 5 As shown, for example, the engaging protrusion 121 includes an arched protrusion including a cut surface; a side wall at one end of the engaging groove 32 includes a veneer that fits the cut surface, and a protrusion beam 36 that abuts against the protrusion is provided on the side wall at the other end.

[0049] When the snap-fitting protrusion 121 is connected to the snap-fitting groove 32, line contact is achieved between the snap-fitting protrusion 121 and the snap-fitting protrusion 121 through the raised beam 36, that is, the raised beam 36 has a certain height, and the snap-fitting groove 32 and the snap-fitting protrusion 121 are in complete surface contact. The line contact method can absorb assembly tolerances and avoid / reduce damage to the shell snap-fitting structure.

[0050] For example, a round chamfer is provided on the surface of the raised beam 36. The surface of the raised beam 36 is smooth and has a certain contact area, which reduces the probability of falling off and separation.

[0051] The present disclosure also provides an electronic product, including a housing and the housing clamping structure. Figure 6 As shown, the shell includes a first shell 51 and a second shell 52, the hook assembly 1 and the limit assembly 2 are connected to the first shell 51, and the snap assembly 3 is connected to the second shell 52. The hook assembly 1 and the limit assembly 2 are snapped with the snap assembly 3 to achieve a stable connection between the first shell 51 and the second shell 52.

[0052] For example, the electronic product is a laptop computer, a tablet computer or a mobile terminal device. The present disclosure provides a shell clamping structure and an electronic product. When in use, the hook head 12 is pressed between the two rollers 31 to be clamped with the clamping protrusion 121 on the hook head 12 through the clamping groove 32, and the roller 31 is restricted from continuing to rotate by the limiting spring sheet, so as to achieve a stable connection between the hook assembly 1 and the clamping assembly 3.

[0053] In the disclosed embodiment, the snap-on structure is arranged inside the shell without being exposed, thus solving the problem of the shell's aesthetics. In addition, the snap-on structure has a simple structure, low cost and occupies a small space. The snap-on and disassembly operations of the product are simple, and the product is universal, so it can be shared by multiple models and has a wide range of applications.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure.
