Detailed implementation mode

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as up and down, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0033] In the description of the present invention, "a plurality" means more than two. If there is a description of the first and the second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] A notebook computer mainly includes two major parts, a screen part and a main body part. The screen part and the main body part are connected by a rotating shaft, so that the screen part can be flipped relative to the main body part. When the screen part covers the main body part, it can be divided into four shells from top to bottom, and are named A shell, B shell, C shell and D shell in sequence. The C shell and the D shell are assembled to form the main body part, and are used to install the main board and other components inside. More specifically, the C shell is the upper cover of the main body part and is also the shell part surrounding the keyboard, palm rest and touchpad.

[0036] As laptops are becoming thinner and lighter, the thickness of the C case is also gradually decreasing. Even if the C case itself is made of metal materials, such as aluminum alloy, its thickness and large area still make it weak and prone to deformation, affecting the appearance of the laptop. Because the main components of the laptop, such as the motherboard, are assembled between the C case and the D case, and some components are also fixed on the C case due to limited space, if the C case is deformed, there is a risk that the internal components will be displaced and affect the normal operation of the laptop. For example, if the metal parts on the C case are displaced and overlap with the electronic components on the circuit board, it will cause a short circuit.

[0037] Reference Figure 1 As shown, a laptop computer C case according to an embodiment of the present invention includes a C case body 100 , a first reinforcing member 200 , a second reinforcing member 300 and a third reinforcing member 400 .

[0038] The C case body 100 has a plate body 110 , and side plates 120 are arranged around the plate body 110 . The C case body 100 is divided into a first area, a second area and a third area which are adjacent to each other in sequence along the width direction. The second area of ​​the C case body 100 is used to install a keyboard.

[0039] The plate body 110 is the largest part of the C shell body 100, and the keyboard installed in the second area is located at the plate body 110. The plate body 110 is surrounded by side panels 120, which are used to connect to the D shell to assemble the host part. The motherboard of the laptop is set between the C shell and the D shell. At the same time, various holes can also be opened on the side panel 120 for electrical connection between external devices and the motherboard. For example, the side panel 120 is provided with a number of USB interface holes, HDMI interface holes, RJ45 network port holes, power adapter interface holes, etc.

[0040] The width direction of the C-shell body 100 is perpendicular to the direction of the flip axis of the screen part. That is, when the C-shell body 100 is viewed from the front, the width direction of the C-shell body 100 is the up-down direction. On the C-shell body 100, the first area, the second area and the third area are adjacent in sequence along the width direction. Generally, the shaft for connecting the screen part and the host part is set in the first area, the keyboard is set in the second area, and the palm rest and touchpad are set in the third area.

[0041] To increase the structural strength of the keyboard position, a second reinforcing member 300 is attached to the second region of the board body 110. The second reinforcing member 300 is made of plastic material. The purpose is that when installing the keyboard, the keyboard can be heat-melted with the plastic of the second reinforcing member 300 to fix the keyboard on the C-shell main body 100. If the second reinforcing member 300 is made of metal material, although the metal material has higher strength than plastic, the keyboard cannot be heat-melted and installed with the metal material, and the assembly process of the keyboard needs to be changed. For example, screws are used to lock the keyboard on the metal material, which undoubtedly increases the difficulty of the process. At the same time, the installation process of the keyboard that can be completed by one heat-melting has become multiple screw-locking processes, which virtually increases the assembly cost.

[0042] To increase the structural strength of the first region and the third region, the first reinforcing member 200 can be attached to the first region, and the third reinforcing member 400 can be attached to the third region, and it is necessary to ensure that the material strength of the first reinforcing member 200 and the third reinforcing member 400 is higher than that of the second reinforcing member 300.

[0043] The components installed in the first region and the third region do not require heat-melting operations, so the first reinforcing member 200 and the third reinforcing member 400 can both be made of metal materials. It should be understood that the first reinforcing member 200 and the third reinforcing member 400 can be made of the same metal material or different metal materials. For the convenience of production and manufacturing, the first reinforcing member 200 and the third reinforcing member 400 are made of the same metal material. Preferably, the C-shell main body 100 is made of aluminum alloy material, the first reinforcing member 200 is made of magnesium alloy material, the second reinforcing member 300 is made of plastic material, and the third reinforcing member 400 is made of magnesium alloy material.

[0044] Refer to Figure 2 As shown, it can be understood that the board body 110 is provided with a power hole 101, the power hole 101 is located in the first region, the board body 110 is provided with a plurality of keyboard holes 102, and the plurality of keyboard holes 102 are all located in the second region. The board body 110 is provided with a touchpad hole 103, and the touchpad hole 103 is located in the third region. The first reinforcing member 200 is provided with a hole corresponding to the power hole 101, the second reinforcing member 300 is provided with a hole corresponding to the keyboard holes 102, and the third reinforcing member 400 is provided with a hole corresponding to the touchpad hole 103.

[0045] The power hole 101 is used to install the power-on button, and the power-on button controls the startup signal of the main board. To facilitate the user to start the main board to run the system, the power-on button needs to be led to the surface of the C-shell main body 100. Therefore, the power hole 101 penetrates the board body 110, and its structural strength is lower than the complete part of the board body 110. The first reinforcing member 200 is provided with a hole corresponding to the power hole 101, and the first reinforcing member 200 can cover the position around the power hole 101 to enhance the structural strength around the power hole 101.

[0046] The keyboard hole 102 is used to lead the key caps of the keyboard to the surface of the C-shell main body 100 for the user to press the key caps to input content. Similarly, the keyboard hole 102 penetrates the board body 110, and its structural strength is lower than that of the complete part of the board body 110. The second reinforcing member 300 is provided with a hole corresponding to the keyboard hole 102, and the second reinforcing member 300 can cover the position around the keyboard hole 102 to enhance the structural strength around the keyboard hole 102.

[0047] The touchpad hole 103 is used to lead the touch surface of the touchpad to the surface of the C-shell main body 100 for the user to slide on the touch surface to control the cursor. Similarly, the touchpad hole 103 also penetrates the board body 110, and its structural strength is lower than that of the complete part of the board body 110. The third reinforcing member 400 is provided with a hole corresponding to the touchpad hole 103, and the third reinforcing member 400 can cover the position around the touchpad hole 103 to enhance the structural strength around the touchpad hole 103.

[0048] It can be understood that the side plate 120 is provided with at least one groove 104, the groove 104 opens in a direction away from the board body 110, the groove 104 is located in the first region, and the first reinforcing member 200 extends to the periphery of the groove 104.

[0049] The groove 104 on the side plate 120 has lower structural strength compared to the holes on the side plate 120 because the groove 104 needs to open in a direction away from the board body 110, and there is no material restriction at the opening, making it more prone to bending and deformation. Therefore, the first reinforcing member 200 needs to extend to the periphery of the groove 104 to improve the structural strength around the groove 104. Generally speaking, it is preferred to open holes on the side plate 120 to meet the connection between the main board and external devices. However, the interface types of different external devices are different, and their sizes are naturally different. For example, the size of the USB interface is larger than that of the 3.5 mm headphone jack, and the size of the RJ45 network port is larger than that of the USB interface. As laptop computers tend to be thinner and lighter, the height of the side plate 120 gradually decreases, and the sizes of some interfaces are relatively large and cannot continue to be set in the form of holes on the side plate 120. Therefore, it is necessary to open grooves 104 on the side plate 120. In addition, the heat dissipation air outlet of the laptop computer is often designed in the first region. Therefore, at least one groove 104 is provided, and this groove 104 is located in the first region and used as a heat dissipation port. Refer to Figure 3 As shown, the first reinforcing member 200 is synchronously provided with a heat dissipation part 210, the heat dissipation part 210 extends to the heat dissipation port, and a plurality of through heat dissipation channels are provided on the heat dissipation part 210.

[0050] It should be understood that when the groove 104 is used as an interface, it is not limited to the first region. For example, it can also be set in the third region.

[0051] It is understandable that a first positioning structure is provided on the surface of the plate body 110, a second positioning structure is provided on the first reinforcing member 200, the first positioning structure and the second positioning structure are in positioning cooperation, and / or a third positioning structure is provided on the second reinforcing member 300, the first positioning structure and the third positioning structure are in positioning cooperation, and / or a fourth positioning structure is provided on the third reinforcing member 400, and the first positioning structure and the fourth positioning structure are in positioning cooperation.

[0052] In some embodiments, the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 need to maintain a correct relative position with the plate body 110 to be attached to the plate body 110. For example, in this embodiment, a power hole 101 is provided on the plate body 110, and the corresponding hole on the first reinforcing member 200 needs to coincide with the power hole 101; a plurality of keyboard holes 102 are provided on the plate body 110, and the corresponding holes on the second reinforcing member 300 need to coincide with each keyboard hole 102; a touchpad hole 103 is provided on the plate body 110, and the corresponding hole on the third reinforcing member 400 needs to coincide with the touchpad hole 103.

[0053] If the first positioning structure, the second positioning structure, the third positioning structure, and the fourth positioning structure are pre-set at a fixed relative distance, then when assembling the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400, the first positioning structure can be in positioning cooperation with the second positioning structure, the first positioning structure can be in positioning cooperation with the third positioning structure, and the first positioning structure can also be in positioning cooperation with the fourth positioning structure, and all three reinforcing members can be attached to the plate body 110 at the correct positions.

[0054] It is understandable that in one embodiment, referring to Figure 4 as shown, the first positioning structure is a counterbore. The plate body 110 has a fitting surface, the counterbore is provided on the fitting surface, the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 are all attached to the fitting surface. The first reinforcing member 200 is provided with a plurality of first through holes 201, the second reinforcing member 300 is provided with a plurality of second through holes 301, the third reinforcing member 400 is provided with a plurality of third through holes 401, and the counterbore is in positioning cooperation with the first through holes 201, the second through holes 301, and the third through holes 401.

[0055] The above structure can achieve the positioning of the plate body 110 and the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 in two ways.

[0056] In the first method, the C-shell main body 100 is placed on the assembly station. The assembly station is provided with marks. By determining the relative positions of the marks and the counterbores on the C-shell main body 100, the placement position of the C-shell main body 100 is located. Then, when placing the first reinforcing member 200, the placement position of the first reinforcing member 200 is determined by the relative position between the first through-hole 201 and the marks, thereby indirectly determining the position between the first reinforcing member 200 and the C-shell main body 100. Similarly, the positions between the second reinforcing member 300, the third reinforcing member 400 and the C-shell main body 100 can also be indirectly determined.

[0057] In the second method, the C-shell main body 100 is directly placed on the assembly station. The first through-hole 201 is coaxial with the counterbore on the C-shell main body 100. Therefore, by using a positioning post to pass through the first through-hole 201 and embed it into the counterbore, the positioning between the first reinforcing member 200 and the C-shell main body 100 can be achieved. After the first reinforcing member 200 is attached, the positioning post can be removed. Similarly, the positioning between the second reinforcing member 300, the third reinforcing member 400 and the C-shell main body 100 can also be completed.

[0058] It can be understood that the C-shell main body 100 is provided with an installation position for installing a rotating shaft. The installation position is in the first area. The first reinforcing member 200 is provided with a plurality of reinforcing columns 220, and the plurality of reinforcing columns 220 are arranged at the installation position.

[0059] The C-shell and the D-shell are assembled to form the main body of the host. To repair the motherboard inside the main body of the host, the disassembly function needs to be retained. Since the keyboard is installed on the C-shell main body 100 and it is not convenient to disassemble from the C-shell, it is preferably disassembled from the D-shell. At the same time, the rotating shaft for connecting the main body of the host and the screen part is not expected to be disassembled and moved, so the rotating shaft is generally fixed to the C-shell. Therefore, an installation position is provided on the C-shell main body 100 for installing the rotating shaft.

[0060] When rotating the screen part, the force received by the screen part will be transmitted to the part where the rotating shaft is connected to the C-shell main body 100 through the rotating shaft, that is, the two installation positions of the C-shell main body 100 will be subjected to large stresses. To avoid deformation at the installation positions, a plurality of reinforcing columns 220 are provided at the corresponding positions of the first reinforcing member 200 to further improve the structural strength. For example Figure 5 the structure shown.

[0061] It should be understood that in some specific embodiments, preferably, the C-shell main body 100 is provided with two installation positions for installing the rotating shaft. The two installation positions are respectively located at two corners of the C-shell main body 100 and both installation positions are in the first area. The first reinforcing member 200 is provided with a plurality of reinforcing columns 220, and a plurality of reinforcing columns 220 are arranged at each installation position. The two installation positions are used to fix the two ends of the rotating shaft, and the rotating shaft is more balanced in force when rotating.

[0062] It should be understood that the strengthening column 220 can also serve as the installation base for the rotating shaft, that is, the rotating shaft is connected to the strengthening column 220 through the fixing part. For example, screw connection is used, and the screw rotates into the strengthening column 220.

[0063] It can be understood that a plurality of raised reinforcing ribs 230 are provided on the surface of the first reinforcing member 200.

[0064] The reinforcing ribs 230 can further increase the strength of the first reinforcing member 200, that is, the reinforcing ribs 230 can be arranged at positions where the strength needs to be further improved. It should be understood that the second reinforcing member 300 and the third reinforcing member 400 can also be correspondingly provided with reinforcing ribs.

[0065] It can be understood that the plurality of strengthening columns 220 are connected by the reinforcing ribs 230.

[0066] The reinforcing ribs 230 connect the plurality of strengthening columns 220 to form a whole. Compared with the scattered strengthening columns 220, the overall structure of the strengthening columns 220 connected by the reinforcing ribs 230 has higher structural strength.

[0067] It can be understood that the thickness of the first reinforcing member 200 and the third reinforcing member 400 is 0.6 mm to 1 mm, and the thickness of the second reinforcing member 300 is 1 mm to 1.4 mm.

[0068] The first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 should neither be too thick nor too thin. In order to reserve installation space for the remaining components, the thicknesses of the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 cannot be greater than the above ranges. In order to ensure that the C-shell main body 100 has sufficient strength, the first reinforcing member 200, the second reinforcing member 300, and the third reinforcing member 400 cannot be less than the above ranges. It should be understood that since the material strength of the second reinforcing member 300 itself is less than that of the first reinforcing member 200 and the third reinforcing member 400, the thickness of the second reinforcing member 300 can be slightly thicker than that of the first reinforcing member 200 and the third reinforcing member 400. Preferably, the thickness of the first reinforcing member 200 and the third reinforcing member 400 is selected as 0.8 mm, and the thickness of the second reinforcing member 300 is selected as 1.2 mm.

[0069] A notebook computer according to an embodiment of the present invention includes the above-mentioned notebook computer C-shell.

[0070] The laptop shell assembled with the C shell of the present application has high strength and less cost increase. Specifically, the C shell body is divided into three regions. The second region is used to install the keyboard. The second reinforcing member made of plastic material is attached to the plate body to improve the structural strength of the C shell body, and at the same time ensure that the keyboard can still be heat-melted with the second reinforcing member made of plastic material to be fixed on the C shell body, with low process difficulty and low cost. The first region and the third region are respectively attached with the first reinforcing member and the third reinforcing member whose material strength is greater than that of the second reinforcing member to increase the structural strength of the corresponding regions of the C shell body and prevent deformation.

[0071] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains.
