[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0044] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0045] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0046] Example 1

[0047] This embodiment takes a notebook computer among electronic products as an example.

[0048] Combination Figure 1 As shown, an embodiment of the utility model provides a laptop computer protective case, which is at least used to protect the laptop computer shell, such as protecting the upper cover of the laptop computer. It should be understood that the laptop computer protective case can also include protection for the keyboard part. The laptop computer described in the utility model refers to a portable computer, including both a laptop computer with an integrated display screen and a keyboard, a computer with a detachable display screen and a keyboard (such as a combination of a tablet computer and a detachable keyboard), and the tablet computer itself. The laptop computer protective case includes: a protective case body 1, at least one accommodating space is provided at both side edges and the top edge of the protective case body 1; one or more magnetic suction components 2, the magnetic suction component 2 is embedded in each accommodating space and the appearance is completely shielded by the protective case body.

[0049] In the embodiment of the utility model, the protective shell body 1 is sleeved on the upper cover of the laptop computer. By setting the magnetic suction component 2 in the protective shell of the laptop computer, the tightly suction of the adsorbed product (such as a mobile phone) is achieved, and there is no need to consider the gravity balance problem between the upper cover of the laptop computer and the adsorbed product. The magnetic suction component 2 can provide a large magnetic suction force, and multiple accommodating spaces can be set in the protective shell body 1 to place multiple magnetic suction components 2, which is convenient for selecting the position of the adsorbed product and easy to use. The accommodating space is set at the two side edges and the top edge of the protective shell body 1, which can ensure that the camera or most of the display screen of the adsorbed product is not blocked, and it is highly practical.

[0050] In actual application scenarios, users can attach their mobile phones or other electronic products to the laptop protective case while using the computer, that is, attach the electronic products to the laptop cover, making it convenient for users to use other electronic products while using the laptop, such as turning on the rear camera of other electronic products to take pictures.

[0051] Combination Figure 1-2 As shown, the magnetic attraction component 2 is composed of a plurality of magnets 21 .

[0052] In this embodiment, the magnetic attraction component 2 is designed into different shapes according to different needs of users, and multiple magnets 21 are used to conveniently splice into magnetic attraction components 2 of different shapes. Specifically, a magnetic attraction sheet 22 is provided below the magnetic attraction component 2, and the magnetic attraction sheet 22 arranges the magnets 21 in a specified position by adsorption, and magnetic attraction components 2 of different shapes can be combined according to magnetic attraction sheets 22 of different shapes.

[0053] Furthermore, the magnetic attraction component 2 is annular and is composed of a plurality of magnets 21; or the magnetic attraction component 2 is an annular magnet. Preferably, the effect will be better if it is composed of a plurality of magnets 21, because the specifications of annular magnets are unconventional and need to be customized separately, which has a higher production cost.

[0054] In this embodiment, the magnetic attraction component 2 is arranged in a circular ring shape, which can provide the largest adsorption surface when using equal amounts of magnets 21. Specifically, the magnet 21 is in the shape of a fan ring, and the S poles are uniformly located at the periphery, or the N poles are uniformly located at the periphery. When in this arrangement, the magnetic field lines of the magnetic attraction component 2 are concentrated on the side without the magnetic attraction sheet 22. The magnetic attraction sheet 22 is arranged at the end of the magnetic attraction component 2 away from the adsorbed product, thereby enhancing the magnetic attraction force on the adsorbed product. More specifically, the optimal thickness of the magnet 21 is 1-1.5mm, preferably 1.2mm. Increasing the thickness of the magnet 21 can increase the magnetic force, but excessive thickness is not conducive to accommodating the magnetic attraction component 2 in the protective shell body, and is not aesthetically pleasing.

[0055] Considering the application scenarios of the magnetic component 2, when it is used for magnetic mobile phone products, it is necessary to consider the gravity and magnetic effect of the bare phone and the phone with a phone case at the same time; and in order to take into account the aesthetics, the following parameter requirements need to be met during the design:

[0056] a. The magnetic attraction force of the magnetic attraction component needs to reach: bare phone ≥ 0.85kg with phone case ≥ 1.5kg;

[0057] b. The thickness of the first accommodating portion + the second accommodating portion ≥ the thickness of the magnetic attraction component.

[0058] Furthermore, the protective shell body 1 includes: a first protective layer 12, a second protective layer 13 and a third protective layer 14 arranged in sequence from the outside to the inside, the accommodating space includes a first accommodating portion 11 and is arranged on the first protective layer 12, and the second protective layer 13 is provided with a second accommodating portion 131 corresponding to the first accommodating portion 11.

[0059] In this embodiment, the multi-layer protective layer can improve the protective effect of the laptop cover. The first accommodating portion 11 is arranged on the first protective layer 12 and is used to accommodate the magnetic component 2, so that the magnetic component 2 is closer to the adsorbed product and provides a stronger magnetic attraction. The second accommodating portion 131 is arranged to avoid affecting the magnetic component 2, so that the protective shell body 1 can accommodate a thicker magnetic component 2; so that the appearance of the magnetic component 2 is completely covered by the protective shell body 1 or does not protrude from the outer surface of the protective shell body 1. Specifically, a filling block 23 is arranged in the magnetic component 2 to avoid affecting the protective effect of the protective shell body 1 due to the second accommodating portion 131 of the second protective layer 13, fill the accommodating space, and stabilize the magnetic component 2. More specifically, the first protective layer 12 is a carbon fiber layer, the carbon fiber has high strength, can provide surface hardness, and has a good feel. The second protective layer 13 is a glass fiber layer or a PC layer, which can provide hardness support. The third protective layer 14 is an ultra-fiber layer, which can cover the magnetic component 2 and protect the laptop cover. At this time, the area of ​​the second protective layer 13 located in the middle can be smaller than the area of ​​the first protective layer 12, so that the protective shell body 1 is lighter and thinner.

[0060] It can be understood that the protective shell body 1 of this embodiment can also be used to protect the screen of a laptop computer.

[0061] Among them, the third protective layer 14 covers the outer surface of the laptop screen, the second protective layer 13 covers the outer surface of the third protective layer 14, and the first protective layer 12 covers the outer surface of the second protective layer 13. It can be understood that the third protective layer 14 is located in the innermost layer and contacts the laptop screen; the second protective layer 13 is located in the middle layer, mainly to increase the thickness of the first protective layer 12 or the third protective layer 14 to accommodate the magnetic suction component 2; the first protective layer 12 is located in the outermost layer as an external contact surface with an anti-slip design. Preferably, the surface roughness of the first protective layer 12 is greater than the surface roughness of the third protective layer 14. The roughness requirement can increase the firmness of the adsorbed object and prevent displacement.

[0062] Example 2

[0063] This embodiment takes a notebook computer among electronic products as an example.

[0064] Combination Figure 3 As shown, the magnetic attraction component 2 is a strip composed of a plurality of magnets 21 arranged in sequence; or the magnetic attraction component 2 is a strip-shaped magnet. Preferably, the effect will be better if it is composed of a plurality of magnets 21, because the specifications of the strip-shaped magnets are unconventional and need to be customized separately, which has a higher production cost.

[0065] In this embodiment, the magnetic attraction component 2 is configured to be a long strip. The long strip can provide the most adsorption positions when using the same amount of magnets 21 as in Embodiment 1, making it convenient to adjust the position of the adsorbed product on the cover of the laptop computer, and the adjustment is convenient and quick.

[0066] Furthermore, the magnets 21 in the magnetic attraction assembly 2 are arranged in a staggered manner.

[0067] In this embodiment, the magnets 21 are arranged in a staggered manner and form a long strip, which increases the adsorption area of ​​the magnetic component 2, prevents the adsorption surface from being single and causes the adsorbed product to rotate around the adsorption position, and improves the stability of adsorption. For this embodiment, it is particularly suitable when the adsorbed electronic product is a magnetic light bar or a light bulb.

[0068] Furthermore, the magnetic attraction component 2 located at the top edge is connected to the magnetic attraction components 2 at both side edges.

[0069] In this embodiment, the magnetic suction component 2 on the top edge is connected to the magnetic suction components 2 on both side edges, so that both side edges and the top edge of the protective shell body 1 can absorb the adsorbed product, which is convenient for adjusting the adsorbed product on the laptop cover.

[0070] Example 3

[0071] This embodiment takes a notebook computer among electronic products as an example.

[0072] Combination Figure 4As shown, the magnetic attraction component 2 is a spiral composed of a plurality of magnets 21 arranged around each other, or the magnetic attraction component 2 is a spiral magnet. Preferably, the effect will be better if it is composed of a plurality of magnets 21, because the specifications of the spiral magnet are unconventional and need to be customized separately, which has a higher production cost.

[0073] In this embodiment, the magnetic attraction component 2 is arranged in a spiral shape, and the distance between the multiple magnets 21 of the spiral magnetic attraction component 2 is reduced relative to that of embodiment 1. The magnets 21 are more concentrated, and can provide a stronger magnetic attraction force. The adsorption points are uniform and are not easily limited by the shape of the adsorbed product.

[0074] Example 4

[0075] Further improvements are made on the basis of embodiments 1 / 2 / 3 to achieve wireless charging.

[0076] Furthermore, a wireless charging component is provided at a position of the protective shell body 1 corresponding to the magnetic attraction component 2 .

[0077] In this embodiment, the wireless charging component can charge the adsorbed electronic products to improve the endurance of the adsorbed products. Taking embodiment 1 as an example, a wireless coil is embedded in the middle position of the magnetic component 2, and the wireless coil is extended to the outside of the shell through a wire and connected to the power supply. Mobile phones and other electronic products can be charged while being magnetically attracted, which increases the functionality of the laptop protective case. In embodiments 2, 3, etc., the wireless coil can be embedded in the gap or peripheral position of the magnetic component 2.

[0078] Example 5

[0079] Further improvements are made on the basis of embodiments 1 / 2 / 3 to achieve wired charging.

[0080] Furthermore, a PIN pin is provided at or near the position of the protective shell body 1 corresponding to the magnetic attraction component 2. For example, a first PIN pin is provided around the magnet, and a second PIN pin is provided on the shell or itself of a mobile phone or other product, and the first PIN pin extends to the outside of the protective shell body through a wire. When the power is turned on, the current is conducted through the contact between the first PIN pin and the second PIN pin, completing the charging function of the mobile phone or other product.

[0081] In this embodiment, the PIN pin can be connected to and charge the adsorbed electronic product which is also provided with the PIN pin, thereby improving the battery life of the adsorbed product. For some electronic products, they do not have a PIN pin themselves. In this case, the PIN pin can be realized through a matching electronic product protective shell.

[0085] It is understandable that in this embodiment, the first protective layer 12 and the second protective layer 13 can be two separate sheets, or two surfaces of the same sheet. In this case, the area of ​​the first protective layer 12 and the area of ​​the second protective layer 13 can be smaller than the area of ​​the third protective layer 14, making the protective shell body 1 thinner and lighter.

[0086] In this embodiment, the accommodation space includes a first accommodation portion 11 disposed on the side of the third protective layer 14 close to the second protective layer 13, and a second accommodation portion 131 disposed on the second protective layer 13 corresponding to the first accommodation portion 11. The magnetic attraction component 2 is accommodated in the space formed by the first accommodation portion 11 and the second accommodation portion 131.

[0087] In this embodiment, the second accommodating portion 131 penetrates the second protective layer 131.

The magnetic component 2 also includes a sheet-shaped filling block 23, and the filling block 23 is filled into the hollow portion to avoid or reduce the thickness variation of the protective shell body 1 at the magnetic component 2. Preferably, the filling block 23 is tightly connected to the second protective layer 13 as a whole. In the present embodiment, the filling block 23 is formed by stacking a number of thin sheets, and the appropriate number of thin sheets can be selected for stacking according to the thickness requirements. The filling block 23 can be a fiberglass sheet, and the second protective layer 13 can also be a fiberglass sheet, which is convenient for being tightly connected into a whole during the manufacturing process.

[0089] In this embodiment, the magnetic attraction component 2 includes a magnetic attraction sheet 22 and a plurality of magnets 21 disposed on a certain surface of the magnetic attraction sheet 22 . The magnetic attraction sheet 22 is located on a side of the plurality of magnets 21 close to the third protective layer 14 .

[0090] In this embodiment, a visual mark 113 is provided between the first protective layer 12 and the third protective layer 14. The visual mark 113 may be a nameplate or a decorative sheet.
