Abstract

The present invention relates to the field of electronic product assembly technology, particularly involving a structural plate and a laptop. The structural plate is mounted in a rear shell of the laptop and snap into a front frame. The structural plate includes a structural plate body. A cantilever is set on the structural plate body. A snap part is set on the cantilever for snapping with the front frame. The structural plate body has a first surface facing the rear shell when installed. An outer surface of the cantilever tapers inward relative to the first surface. This solution makes the hook of the front frame only need to spend a small amount of force to push the cantilever to complete the snap connection with the snap part, thereby reducing the difficulty of mount between the front frame and the structural plate. After the structural plate body is mounted in the rear shell, there is a gap between the outer surface of the cantilever and the inner wall of the rear shell. The gap is the safe displacement generated by the moment, so that the cantilever can be maintained in the elastic stage without breaking.

Description

Structural panels and laptops

An electronic product assembly, especially an electronic product assembly of a structural board and a laptop computer.

When assembling the laptop case, the structural plate is installed in the rear case, and the front frame and rear case are installed together by snapping the hooks on the front frame to the structural plate. The structural plate, front frame and rear case are all aluminum die-casting parts with high hardness, so it is difficult to install the structural plate to the rear case and snap the hooks of the front frame to the structural plate. Each material has an elastic stage and a plastic stage when subjected to force. In the performance of a rigid body, once the force reaches the plastic stage, it will directly break. Therefore, if the force is too large during installation, it may also cause damage to the structural plate or even breakage.

In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a structural board and a laptop computer to solve the problem that the structural board, the front frame and the rear shell are difficult to install and the structural board may be damaged in the prior art.

To achieve the above-mentioned purpose and other related purposes, the present invention provides a structural plate for installation in the rear shell of a laptop computer and clamping with the front frame, the structural plate comprising a structural plate body, a cantilever is provided on the structural plate body, a clamping portion for clamping with the front frame is provided on the cantilever, the structural plate body has a first surface facing the rear shell when installed, and the outer surface of the cantilever is inwardly contracted relative to the first surface.

Optionally, the cantilever is provided with a clamping hole penetrating the cantilever along the thickness direction of the cantilever.

Optionally, the outer surface of the cantilever includes a bottom surface and an arc surface bent toward the front frame, and the snap-in hole is provided on the arc surface.

Optionally, the snap-on hole is a square hole.

Optionally, there is a first gap between the two ends of the cantilever along the first direction and the structural plate body.

Optionally, a first supporting part and a second supporting part are provided on the structural plate body, the outer surface of the first supporting part and the outer surface of the second supporting part are used to abut against the inner wall of the rear shell, and a first gap is respectively formed between the two ends of the cantilever along the first direction and the first supporting part and the second supporting part.

Optionally, there is a second gap between the outer surface of the cantilever and the inner wall of the rear shell.

Optionally, the outer surface of the cantilever is parallel to the first surface.

Optionally, the clamping portion has a second plane facing the same direction as the inner surface of the cantilever, and the second plane is lower than the inner surface of the cantilever.

Optionally, a protrusion is provided along the first direction at the connection between the first surface and the cantilever.

The present invention also provides a notebook computer, including the structural board as described above.

As described above, the structural board and laptop computer of the present invention have the following beneficial effects:

In the existing structure, when the front frame is clamped with the structural plate, the clamping hook of the front frame needs a large force to push the entire structural plate body to move away from the clamping hook, making the installation between the front frame and the structural plate more difficult. In this solution, a cantilever is provided on the structural plate body, and a clamping part for clamping with the front frame is provided on the cantilever, so that the clamping hook of the front frame only needs to spend a small force to push the cantilever to complete the clamping with the clamping part, thereby reducing the difficulty of installation between the front frame and the structural plate. The structural plate body has a first surface facing the rear shell during installation, and the outer surface of the cantilever shrinks inward relative to the first surface, so that after the structural plate body is installed in the rear shell, there is a gap between the outer surface of the cantilever and the inner wall of the rear shell. This gap is the safety displacement generated by the torque of the front frame hook pushing the cantilever outward when the front frame hook is engaged with the cantilever. Under this safety displacement, the cantilever can always maintain the elastic stage without breaking.

Please refer to "Figure 1", "Figure 2", "Figure 4" and "Figure 5". This embodiment provides a structural board, which is installed in the rear shell 2 of the notebook computer and is clamped with the front frame 3. The structural board includes a structural board body 1, a cantilever 11 is provided at the right end of the structural board body 1, a clamping portion 111 for clamping with the front frame is provided at the top of the cantilever 11, and a clamping hook 31 is provided at the bottom of the front frame 3, and the clamping portion 111 cooperates with the clamping hook 31. The structural board body 1 has a first surface facing the rear shell 2 when installed, and the first surface is the outer surface of the structural board body 1. The outer surface of the cantilever 11 shrinks toward the inside of the structural plate body 1 relative to the first surface, that is, the right side of the cantilever 11 shrinks toward the left relative to the outer surface of the structural plate body 1, and the bottom of the cantilever 11 rises upward relative to the bottom plane of the structural plate body 1. The bottom of the cantilever 11 is connected to the structural plate body 1, and the top of the cantilever 11 is a free end.

The rear shell 2 is arranged at the bottom, the structural plate is arranged in the rear shell 2, and the first surface of the structural plate body 1, that is, the outer surface of the structural plate body 1, is mounted on the inner wall of the rear shell 2. The front frame 3 covers the rear shell 2, and the hook 31 on the front frame 3 is engaged with the engaging portion 111, so that the rear shell 2 and the front frame 3 are mounted together. In the existing structure, when the front frame 3 is engaged with the structural plate, the hook 31 of the front frame 3 needs a large force to push the entire structural plate body 1 to move away from the hook 31, making the installation between the front frame 3 and the structural plate more difficult. In this solution, a cantilever 11 is provided on the structural plate body 1, and a clamping portion 111 for clamping with the front frame 3 is provided on the cantilever 11, so that the hook 31 of the front frame 3 only needs to spend a small force to push the cantilever 11 to complete the clamping with the clamping portion 111, thereby reducing the difficulty of installation between the front frame 3 and the structural plate. The structural plate body 1 has a first surface facing the rear shell 2 during installation. The outer surface of the cantilever 11 shrinks inward relative to the first surface, so that after the structural plate body 1 is installed in the rear shell 2, there is a gap between the outer surface of the cantilever 11 and the inner wall of the rear shell 2. When the hook 31 of the front frame 3 is engaged with the cantilever 11, the hook 31 of the front frame 3 pushes the cantilever 11 outward. The gap is a safe displacement generated by the torque. Under this safe displacement, the cantilever 11 can always maintain the elastic stage without breaking.

In one embodiment, as shown in "Figure 1", "Figure 4", "Figure 5" and "Figure 6", a clamping hole 112 is provided on the cantilever 11, which penetrates the cantilever 11 along its thickness direction. The clamping part 111 is provided at the top of the clamping hole 112, and the clamping hook 31 of the front frame 3 moves downward, pushes the clamping part 111 to the right and enters the clamping hole 112. The clamping part 111 is reset after losing the squeeze of the clamping hook 31, and the clamping hook 31 is hooked at the bottom of the clamping part 111, and the clamping installation is completed. The above setting method has simple process, easy installation and clamping, and high efficiency.

In one embodiment, as shown in FIG. 4 , the outer surface of the cantilever 11 includes a bottom surface 114 and a vertically arranged arc surface 115 connected to the bottom surface 114. The arc surface 115 is bent toward the front frame 3 during installation, and the snap-in hole 112 is opened on the arc surface 115.

In one embodiment, as shown in "Figure 5", the clamping hole 112 is a square hole, which is simple and easy to process.

In one embodiment, as shown in "Figure 1" and "Figure 5", there is a first gap 12 between the two ends of the cantilever 11 along the first direction and the structural plate body 1, and the two ends of the cantilever 11 along the first direction are disconnected from the structural plate body 1, so that the cantilever 11 is easier to push and squeeze relative to the right end of the structural plate body 1.

In one embodiment, as shown in FIG. 1 , a first supporting portion 16 and a second supporting portion 17 are provided on the structural plate body 1, and the first supporting portion 16, the cantilever 11 and the second supporting portion 17 are arranged in sequence along the first direction. The outer surface of the first supporting portion 16 abuts against the inner wall of the rear shell 2, and the outer surface of the second supporting portion 17 abuts against the inner wall at the corner of the rear shell 2. The first supporting portion 16 and the second supporting portion 17 support the inner wall of the rear shell 2, so that the outer surface of the cantilever 11 can shrink inward relative to the first surface. The cantilever 11 and the second supporting portion 17 are disconnected at the corner, and the strength at the corner is greater. Disconnection at the corner can further make it easier for the cantilever 11 to be pushed outward. There is a first gap 12 between the rear end of the cantilever 11 along the first direction and the second supporting portion 17, and there is also a first gap 12 between the front end of the cantilever 11 along the first direction and the first supporting portion 16.

In one embodiment, as shown in FIG. 2 and FIG. 3 , there is a second gap 15 between the outer surface of the cantilever 11 and the inner wall of the rear shell 2, that is, between the right side of the clamping portion 111 and the inner wall of the rear shell 2, and between the outer surface of the bottom of the cantilever 11 and the inner wall of the rear shell 2. When the clamping portion 111 is clamped with the hook 31, there is a safety displacement generated by the torque between the right side of the clamping portion 111 and the inner wall of the rear shell 2, so that the cantilever 11 can always be maintained in the elastic stage without breaking. When the structural panel body 1 is installed on the rear shell 2, there is a safe displacement caused by torque between the bottom outer surface of the cantilever 11 and the inner wall of the rear shell 2, and the cantilever 11 can always remain in the elastic stage without breaking.

In one embodiment, as shown in FIG. 1 , the outer surface of the cantilever 11 is parallel to the first plane.

In one embodiment, as shown in "Figure 2" and "Figure 6", the clamping portion 111 has a second plane 1111 facing the same direction as the inner surface of the cantilever 11, and the second plane 1111 is arranged toward the left side. The second plane 1111 is further to the right relative to the inner surface of the cantilever 11, which reduces the difficulty of the hook 31 being clamped into the clamping portion 111.

In one embodiment, as shown in "Figure 1", "Figure 2", "Figure 3" and "Figure 5", a long strip-shaped protrusion 13 is provided along the first direction at the connection between the first surface and the cantilever 11, that is, a long strip-shaped protrusion 13 is provided along the first direction at the connection between the bottom plane of the structural plate body 1 and the cantilever 11. When the cantilever 11 generates a torque, the protrusion 13 can be used as a fulcrum to make the cantilever 11 easier to push and squeeze.

This embodiment also provides a laptop computer, including the structural board as described above.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with this technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by a person with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed by the present invention shall still be covered by the scope of the patent application of the present invention.
