Description

Technical Field

[0001] This application relates to the technical field of electronic products. Background Art

[0002] In existing electronic devices such as tablet computers and mobile phones, the fixing methods mainly include screw fixing and adhesive fixing. However, after long-term use or multiple disassembly and assembly, the stability of both methods may decrease. The screw fixing method has good stability, but the strength of the screw holes needs to be considered, so it cannot be set at the outermost edge, but only at a position close to the edge. Using only screws for fixing will result in gaps at the edges of the electronic product. This gap will not only affect the overall aesthetics of the product, but also increase the risk of product damage when dropped or impacted.

[0003] The advantage of the adhesive fixing method is that it can firmly fix the electronic device on the substrate, but the adhesive fixing process is relatively cumbersome and requires a series of steps such as surface cleaning, gluing, and waiting for drying. This process not only increases the production cost, but also brings trouble to users when replacing or repairing the electronic device. In addition, the adhesion of glue to different material surfaces will also vary, making it difficult to maintain consistent adhesive fixing effects. If the electronic device is subjected to vibration or impact during use, the glue layer may crack or peel off, causing the electronic device to lose its fixation. In summary, the existing electronic device fixing methods have obvious problems in terms of stability, ease of use, and production efficiency. Summary of the Invention

[0031] Refer to the attached Figure 1 , the attached Figure 1 is a partial exploded view of the fixing structure at the fixing structure provided in an embodiment of an electronic device with a fixing structure according to the present invention. The electronic device with a fixing structure in the embodiment of the present application includes a first housing 1 and a second housing 3 that is snap-fitted with the first housing 1. The first housing 1 and the second housing 3 are combined with each other, and a support is provided inside the second housing 3, and a movable hook 2 is provided on the support. The movable hook 2 can slide partially so that one end of the movable hook 2 moves to the edge of the second housing 3 and is fixed to the edge of the second housing 3.

[0032] Specifically, a first hole for inserting a screw 4 is provided on the first housing 1, and a stud that cooperates with the screw 4 is provided on the second housing 3. A movable hook 2 is provided between the first hole and the stud. The first housing 1 and the second housing 3 are locked by the screw 4. During the locking process of the screw 4, the movable hook 2 moves in the first direction. After the screw 4 is locked, the movable hook 2 is fixed to the second housing 3. A fixed hook is provided on the side wall of the second housing 3, and the fixed hook extends along a direction parallel to the movable hook 2. When the screw 4 passes through the first hole and is inserted into the stud, one end of the movable hook 2 engages with the fixed hook; when the screw 4 is removed from the screw hole, the movable hook 2 returns to its initial position, and one end of the movable hook 2 is separated from the fixed hook.

[0033] See the attached Figure 2 to the attached Figure 7 , the attached Figure 2 is a perspective view of the installation structure of the movable hook and the first housing in an embodiment of an electronic device with a fixing structure according to the present invention; the attached Figure 3 is a schematic structural diagram when the screw contacts the movable hook in an embodiment of an electronic device with a fixing structure according to the present invention; the attached Figure 4 is a schematic structural diagram of the screw pushing the movable hook to achieve fixation in an embodiment of an electronic device with a fixing structure according to the present invention; the attached Figure 5 is a schematic diagram for explaining the angle between the screw and the inclined plane in an embodiment of an electronic device with a fixing structure according to the present invention; the attached Figure 6Perspective view and A-A cross-sectional view of the inclined plane of the movable catch having a flat surface in an embodiment of the electronic device with a fixed structure according to the present invention; Attachment Figure 7 Perspective view and A-A cross-sectional view of the inclined plane of the movable catch having a curved surface in another embodiment of the electronic device with a fixed structure according to the present invention.

[0034] The movable catch 2 is fixed to the first housing 1 through the first mounting structure and the second mounting structure. The first mounting structure includes a first guide rail 21, and a guide post 11 for cooperating with the first guide rail 21 of the movable catch 2 is provided on the first housing 1. The first guide rail 21 includes a large guide rail section for inserting the guide post and a small guide rail section for the guide post to slide. The small guide rail section of the movable catch 2 is a guide rail structure for cooperating with the guide post 11 of the first housing 1. The second mounting structure includes a mounting and positioning structure 12 provided on the first housing 1 for cooperating with the movable catch 2. In other words, the movable catch 2 can be configured to be disposed on the first housing 1, and the first housing 1 is provided with a mounting and positioning structure 12 for fixing the fixed end 24 of the movable catch 2. There is a first hole on the first housing 1, and a second hole 22 through which a screw can pass is provided at the corresponding position of the movable catch 2. The inclined plane is disposed in the second hole 22. When the screw sequentially passes through the first hole and the second hole 22, the screw pushes the inclined plane to move, and further pushes the movable catch 2 to move, finally engaging the movable catch 2 of the first housing 1 and the fixed catch of the second housing 3 to achieve the purpose of fixing the first housing 1 and the second housing 3 to each other. The inclined plane of the movable catch 2 is disposed beside the second hole 22, and when the screw 4 passes through the first hole and contacts the inclined plane, it will push the inclined plane to move. The locking direction of the inclined plane with respect to the screw 4 forms an acute angle. The inclined plane includes a first vertex angle disposed at the top. When the screw 4 is not inserted, the telescopic deformation portion is in a free state. At this time, the first vertex angle is configured below the first housing 1, rather than below the first hole. Before the screw 4 is inserted, the first vertex angle cannot leak out through the first hole.

[0035] A telescopic deformation portion is disposed between the inclined plane and the fixed end. The telescopic deformation portion is a flexible connection portion 23, which deforms and elongates when subjected to an external tensile force and returns to its original state when the external force disappears. When the screw 4 is inserted, as the flexible connection portion 23 is stretched, one end of the movable catch 2 moves towards the end of the second housing 3 and finally engages with the fixed catch at the end of the second housing 3. In some embodiments, the telescopic deformation portion can be a slider. During the process of the inclined plane moving away from the telescopic deformation portion, the slider slides along the fixed portion and follows the inclined plane to reach the locking position. The inclined plane and the flexible connection portion 23 are respectively disposed on both sides of the first hole. As the screw 4 is inserted into the second hole 22, the screw 4 pushes the inclined plane to move away from the flexible connection portion 23.

[0036] The second installation mechanism is arranged beside the flexible connection part 23. During the process of the inclined surface moving away from the flexible connection part 23, the fixing part 24 beside the flexible connection part 23 is fixedly connected to the installation and positioning structure 12 of the first housing, and the flexible connection part 23 is stretched. The movable hook 2 includes an inner end and an outer end. When the movable hook 2 is in the locked position, the outer end of the movable hook 2 is in contact with the second housing 3, and the inner end is fixedly connected to the installation and positioning structure 12 of the first housing 1 through a fixing part 24. When the screw 4 is not in the locked position, the flexible connection part 23 pulls the outer end of the movable hook 2 back to its original position, and the outer end of the movable hook 2 is separated from the fixed hook of the second housing 3. This fixing device occupies a small space, has a double fixing structure, a small installation space, a large locking ability, and can improve safety.

[0037] A screw hole is provided on the second housing 3 at a position corresponding to the first hole. The screw hole is configured to fix the screw 4 when the screw 4 is inserted. The common fixing method includes providing threads in the screw hole. Of course, it can also be other fixing methods. The fixing method of the screw 4 does not limit the protection scope of this application. The fixed hook of the second housing 3 can be provided on the first side of the second housing 3, and the screw hole is provided on the second side. When the screw 4 is inserted into the screw hole from the second side, the inclined surface near the first hole is pushed by the screw 4 and moves towards the first side, and finally the movable hook 2 installed on the first housing 1 and the fixed hook of the second housing 3 are engaged together to achieve the purpose of fixing the first housing 1 and the second housing 3 to each other.

[0038] See attached Figure 5 , the included angle a between the inclination direction of the inclined surface of the movable hook and the moving direction of the screw 4 is an acute angle. The second hole 22 is provided below the first hole. When the screw 4 is inserted into the second hole 22, the inclined surface is pushed by the screw 4 and moves in a direction substantially parallel to the first housing 1. The inclined surface includes a first apex angle adjacent to the first hole, and the first apex angle is configured to be below the first housing 1 so that the inclined surface contacts the screw 4 when the screw 4 is inserted. This application does not limit the shape of the inclined part. The inclined surface can be a plane (see attached Figure 6 ), or it can be a curved surface (see attached Figure 7 ).

[0039] See attached Figure 3 to attached Figure 5 , the projected length b of the inclined part in the horizontal direction is b = c + d + e + f; where c is the distance from the first apex angle to the first hole; d is the distance between the movable hook and the fixed archaeological object before the screw 4 is installed; e is the distance between the screw 4 and the first hole when the screw 4 is inserted into the first hole; f is the length of the coincidence of the movable hook and the fixed hook after the screw 4 is fixed.
