Description

Background board and electronic equipment protective case

Technical field

[0001] The present invention relates to the technical field of electronic equipment accessories, and in particular to a background plate and an electronic equipment protective shell. [Background Technology]

[0002] Current electronic device protective cases can be categorized by material, including PC, leather, silicone, hard plastic, leather cases, and soft plastic. These cases not only serve as decorative elements, adding a touch of elegance to your phone, but also protect it from drops, scratches, water, and shock. These cases are used in a variety of applications. As young people chase fashion trends, they frequently change their cases. However, existing protective cases, which are often integrated, are no longer sufficient for their needs, and frequent replacements waste resources.

[0003] The styles of existing single protective cases are relatively simple. When people need to change the protective case of electronic products to another style, they have to replace the entire protective case. Each replacement of the protective case requires a certain cost, which causes unnecessary waste.

[0004] Therefore, a mobile phone case with a detachable background plate has appeared on the market. However, for mobile phone cases that are also equipped with a lens protection frame, the detachable background plate directly avoids the position of the lens protection frame. The connection of the detachable background plate is not strong enough due to the magnetic attraction alone.

[0053] 1 to 3 , a first embodiment of the present invention provides an electronic device protective case 1 for wrapping an electronic device in the protective case 1 for protection, thereby preventing the electronic device from being damaged, scratching the screen or back, and providing waterproof and shockproof functions.

[0054] The electronic device is, for example, a mobile phone. In other embodiments, the electronic device may also be a tablet computer, etc. In this embodiment, the protective case 1 is a square shape adapted to the shape of the mobile phone. In other embodiments, when the mobile phone is of other shapes and sizes, the protective case 1 may also be a correspondingly adapted shape.

[0055] This embodiment provides an electronic device protective case 1, including a main body 10 and a background plate, the background plate including a lens frame, the main body 10 including a frame 101 and a bottom plate 102, the frame 101 and the bottom plate 102 enclose a receiving groove 13 for accommodating the electronic device, and the background plate 11 is detachably connected to a side of the bottom plate 102 away from the receiving groove 13.

[0056] The frame 101 and the bottom plate 102 are not detachable and are formed in one piece, and the background plate 11 has a pattern layer on the side facing away from the bottom plate 102. The pattern layer is used to set patterns and other various beautiful appearances with a certain style, etc., mainly to make the protective shell 1 have a certain beauty and meet the user's requirements for the style of the protective shell 1.

[0057] The two opposite surfaces of the background plate 11 and the bottom plate 102 are parallel to each other, so that the background plate 11 can be completely fitted with the bottom plate 102, and the connection is more stable without leaving any gaps.

[0058] Furthermore, a magnetic member 1023 is provided on the bottom plate 102 , and a magnetic element 113 magnetically attracted to the magnetic member 1023 is provided on the background plate 11 .

[0059] The magnetic component 1023 is arranged in a surrounding manner. In the present embodiment, the magnetic component 1023 is annular. Furthermore, a groove 1022 is provided on the side of the bottom plate 102 facing the receiving groove 13, and the magnetic component 1023 is arranged in the groove 1022. It can be understood that when the magnetic component 1023 is placed in the groove 1022, the exposed outer surface of the magnetic component 1023 does not protrude relative to the side of the bottom plate 102 facing the receiving groove 13, and can be coplanar, so as to prevent the magnetic component 1023 from affecting the placement of the mobile phone, scratching the back shell of the mobile phone, and so on.

[0060] It should be noted that the magnetic component 1023 can be embedded in the groove 1022, or other methods can be used, such as gluing the magnetic component 1023 in the groove 1022; in other embodiments, other feasible embodiments can also be used for fixation. The present invention does not make specific limitations, as long as the magnetic component 1023 is fixed in the groove 1022.

[0061] The background plate 11 includes a magnetic element 113 that is magnetically coupled with the magnetic element 1023. The magnetic element 113 can be set inside the background plate 11 or on any side of the background plate 11.

[0062] Specifically, in this embodiment, the magnetic element 113 is disposed on a surface of the background plate 11 close to the bottom plate 102 .

[0063] It can be understood that the magnetic element 113 can also be a magnet or a material that can be magnetically attracted by a magnet. It is set on the background plate 11 mainly to cooperate with the magnetic attraction part 1023 set on the base plate 102. The specific shape and structure of the magnetic element 113 are not specifically limited, and it is sufficient to achieve the purpose of adsorbing and connecting the background plate 11 to the base plate 102.

[0064] As an optional embodiment, the background board 11 can be a two-layer structure, wherein the layer close to the bottom plate 102 is a magnetic element 113, which uses a magnet or a material that is magnetically attracted by a magnet, and the other layer is used to set the background appearance such as pattern, shape, etc.

[0065] As a preferred solution, the magnetic element 113 is a ring-shaped magnet, which is used to cooperate with the ring-shaped magnetic attraction part 1023. When wireless charging is used to charge the mobile phone, the ring-shaped magnetic element can assist in charging and speed up the charging efficiency; and the ring-shaped magnet can automatically correct its relative position with the wireless charging coil so that it is just facing the charging area, which is convenient for quick positioning for wireless charging.

[0066] The area surrounded by the magnetic element 113 is a charging area, and the electronic device is charged in the charging area.

[0067] Preferably, the magnetic element is set to the position corresponding to the magnetic attraction part 1023, so as to save materials and achieve the same magnetic attraction force. Moreover, since the positions of the two correspond, the background plate 12 can be automatically adjusted to the appropriate position during magnetic adsorption, avoiding the need for manual adjustment by the user.

[0068] Furthermore, in this embodiment, the groove 1022 is an annular groove, and at least one magnetic member 1023 is provided in the annular groove; when there is one magnetic member 1023 , the shape of the magnetic member 1023 matches that of the groove 1022 to form an annular magnetic member 1023 .

[0069] It can be understood that since the magnet is set in a circular shape, the magnetic attraction part 1023 on the base plate 102 can also be used in conjunction with other accessories, such as a wireless charger, etc., which solves the problem of unstable adsorption caused by the decrease in magnetic force when the electronic device with the protective case 1 is placed on the surface of the wireless charger for charging. In addition, since the magnetic attraction part 1023 is set on the base plate 102 and the base plate 102 is firmly mounted on the frame, when the wireless charger is removed, the background plate 12 adsorbed by the base plate 102 will not be removed due to the magnetic effect.

[0070] In other embodiments, multiple magnetic members 1023 may be disposed within the groove 110. When multiple magnetic members 1023 are provided, the multiple magnetic members 1023 are arranged at equal intervals within the groove 1022. It is understood that such an arrangement can also achieve the same beneficial effects as described above and can also ensure uniform magnetic force.

[0071] Furthermore, in other embodiments, a plurality of grooves 110 can be provided, with the plurality of grooves 110 arranged in a ring-shaped array at intervals, a plurality of magnetic elements 1023 can be provided, and one or more magnetic elements 1023 are provided corresponding to each groove 1022. It is understood that such an arrangement achieves nearly the same effect as the above arrangement, but saves more materials.

[0072] Specifically, in this embodiment, the magnetic part 1023 and the magnetic element 113 are both ring-shaped. When wireless charging is used to charge the mobile phone, the ring-shaped magnetic part 1023 and the magnetic element 113 can assist in charging and speed up the charging efficiency; and the ring-shaped magnet can automatically correct its relative position with the wireless charging coil, making it convenient to quickly locate the mobile phone for wireless charging.

[0073] Furthermore, the area on the bottom plate 102 surrounded by the magnetic element 1023 is defined as an inner area, and a disassembly opening 1024 penetrating the bottom plate 102 is defined in the inner area.

[0074] It can be understood that this arrangement not only makes the appearance better, but also makes it easier to remove the background plate 11 by applying force near the position where the magnetic force is the largest. The purpose is to avoid uneven force on the background plate 11 during disassembly, which will cause the background plate 11 to warp after multiple operations.

[0075] Furthermore, the inner area defines a charging zone.

[0076] The inner area is also the charging area. When the background plate 11 is connected to the bottom plate 102, the two charging areas are opposite to each other. The wireless charging coil is positioned and corrected by the magnetic component 1023 and the magnetic element 113 to charge the electronic device at the corresponding position of the charging area.

[0077] Furthermore, corresponding inner lens holes 1021 and outer lens holes 111 are respectively formed on the bottom plate 102 and the background plate 11 , and the lens frame is arranged at the outer lens holes.

[0078] Furthermore, in this embodiment, the lens frame 12 is detachably connected to the outer lens hole 111. It can be understood that when the user replaces the desired background plate 11, he can only choose to replace the background plate 11 and retain the lens frame 12, saving costs.

[0079] The bottom plate 102 and the background plate 11 are respectively provided with an inner lens hole 1021 and an outer lens hole 111, both of which are used to expose the camera of the mobile phone. The lens frame 12 set on the background plate 11 can protect the lens. When the mobile phone accidentally falls, the lens frame 12 can act as a buffer to prevent the lens from directly contacting the ground and being damaged by the huge impact force.

[0080] Referring to FIG. 4 , further, in this embodiment, a separation structure is provided on the background plate 11 , and the separation structure is used to separate the background plate from the electronic device protective shell.

[0081] Specifically, in this embodiment, the lens frame 12 includes a shield 121 located on one side of the background plate 11 and extending in all directions, and the separation structure is at least one notch 123 or at least two oppositely arranged notches 123 opened on the shield 121.

[0082] Specifically, the eaves 121 are located on the side of the background plate 11 away from the bottom plate 102 .

[0083] Among them, in this embodiment, the notch 123 is set on the outer peripheral side of the eaves 121. The notch can be at the bottom, middle, or upper part of the outer peripheral side for hand buckles to facilitate pulling the background plate away from the bottom plate, thereby making it easy to replace the background plate.

[0084] It can be understood that the eaves 121 extend in all directions to cover a portion of the background plate 11 close to the outer lens frame 12, so that the connection with the background plate 11 is more stable and dust is prevented from entering between the background plate 11 and the base plate 102. The hidden design also makes it possible to see only the background plate 11 from the outside.

[0085] In addition, an opening is provided on the eaves 121, so that when removing the background plate 11, you can directly hold the notch 123 to remove the background plate 11 and the lens frame 12 together, reducing the number of operating steps, and then the background plate 11 and the lens frame 12 can be separated through the notch 123.

[0086] It can be understood that with such a structural setting, there is no need to set the aforementioned disassembly port 1024. Both are for the convenience of disassembly, and both can be set at the same time. In this way, when the background plate 11 is lifted using the notch 123, since there is still a magnetic force in the center of the background plate 11, the force applied through the disassembly port 1024 can prevent the background plate 11 from breaking due to forces from two different directions.

[0087] Further, please refer to Figures 4 and 5. The lens frame 12 also includes a snap-on portion 122, which is located on the side of the eaves 121 close to the background board 11. The snap-on portion 122 is provided with at least one protrusion 124, and a slot 125 is formed between the protrusion 124 and the eaves 121; when the lens frame 12 is connected to the background board 11, the inner wall of the outer lens hole 111 is snapped into the slot 125.

[0088] It can be understood that the card slot 125 formed between the protrusion 124 and the eaves 121 is used to clamp the edge position of the background board 11, so that the clamping is more secure, making it difficult for the lens frame 12 to fall off. When disassembling the lens frame 12, you only need to use the notch 123 to pick out the lens frame 12.

[0089] Furthermore, referring to FIG. 6 , the width of the card slot 125 matches the thickness of the background plate 11 .

[0090] As shown in the figure, the width a of the card slot 125 (such as a in Figure 6) and the thickness c of the background plate 11 (such as c in Figure 6) are equal, so that the card connection between the lens frame 12 and the background plate 11 is more firm and tight, preventing the lens frame 12 from shaking and preventing dust from entering.

[0091] Please continue to refer to Figure 2. The inner wall of one side of the outer lens hole 111 is provided with a limiting structure 112. The bottom plate 102 is provided with a protrusion 1025 or a groove at a position corresponding to the limiting structure 112. When the background plate 11 is connected to the bottom plate 102, the protrusion 1025 is at least partially engaged with the limiting structure 112, or the groove accommodates the limiting structure.

[0092] In this embodiment, a protrusion is provided on the bottom plate 102 , wherein the limiting structure is a notch.

[0093] Understandably, since the base plate 102 is magnetically connected to the background plate 11, it is generally not easy to accurately position the background plate 11, which can easily affect the appearance. Usually, magnetic adsorption still requires manual adjustment by the user. However, in this embodiment, by providing a protrusion 1025 and a limiting structure 112, when the base plate 102 and the background plate 11 are not aligned, the background plate 11 cannot be completely and correctly adsorbed on the base plate 102. The protrusion 1025 is used for limiting the position, and no manual adjustment is required after the connection, and the protrusion 1025 also limits the movement of the background plate 11 during use.

[0094] Further, please refer to Figures 2, 3 and 5, in which a first snap-connecting block 1026 is provided on the side of the protrusion 1025 facing the inner lens hole 1021; the snap-connecting portion 122 is provided with a second snap-connecting block 126 that cooperates with the first snap-connecting block 1026; when the background plate 11 is connected to the base plate 102, the protrusion 1025 is at least partially snapped into the limiting structure 112, and the first snap-connecting block 1026 is correspondingly snapped into the second snap-connecting block 126.

[0095] It can be understood that since the lens frame 12 is clamped on the detachable background plate 11, after the background plate 11 is connected to the base plate 102, the second clamping block 126 on the lens frame 12 also cooperates with the first clamping block 1026 on the base plate 102 to further limit the background plate 11, so that the background plate 11 can be firmly and tightly connected to the base plate 102 at the lens frame 12, and dust is not easily introduced.

[0096] Furthermore, when the lens frame 12 is connected to the background plate 11 , one side of the barrier eaves 121 abuts against the background plate 11 , and the barrier eaves 121 covers the limiting structure 112 .

[0097] It can be understood that the eaves 121 are used to cover the limiting structure 112, which not only maintains the appearance but also prevents dust from entering the limiting structure 112.

[0098] Furthermore, the surfaces of the first clamping block 1026 and the second clamping block 126 are arranged in an arc shape.

[0099] It can be understood that the curved surface allows the second clamping block 126 to move more smoothly from one side of the first clamping block 1026 to the other side, thereby completing the clamping or separation, to prevent the interaction force between the first clamping block 1026 and the second clamping block 126 from causing damage during clamping or separation, and there will be no jamming.

[0100] Continuing with FIG6 , further, the thickness b of the clamping portion 122 (see b in FIG6 ) is less than or equal to the total thickness d of the bottom plate 102 and the background plate 11 (see d in FIG6 ). This prevents the clamping portion 122 from partially protruding into the receiving groove 13, keeps the bottom of the receiving groove 13 flat, and prevents scratches on the lens or back cover of the mobile phone.

[0101] Please continue to refer to Figure 2. Furthermore, the side of the bottom plate 102 facing away from the receiving groove 13 and the frame 101 are enclosed to form a limiting groove 14. When the background plate 11 is connected to the bottom plate 102, the background plate 11 is placed in the limiting groove 14.

[0102] It can be understood that by providing the limiting groove 14 to accommodate the background plate 11 , the hand feel of the protective shell 1 can be maintained better, and the background plate 11 will not protrude, thereby affecting the user experience. At the same time, the limiting groove 14 also limits the translation of the background plate 11 .

[0103] Please refer to FIG. 7 , a second embodiment of the present invention provides an electronic device protective case 2 , which differs from the first embodiment in that a lens protection frame 115 is rotatably connected to the back plate 11 .

[0104] It can be understood that when the lens protection frame 115 is opened, it can be used as a bracket to support the electronic device. At the same time, it can also be used as a separation structure to separate the background plate 11 and the electronic device protective shell; when it is not opened, it is used to protect the camera on the electronic device.

[0105] 8 , an electronic device protective case 3 provided in a third embodiment of the present invention differs from the electronic device protective case 1 provided in the first embodiment in that the separation structure is a bracket 114 rotatably connected to one side of the background plate 11 .

[0112] 11 , an electronic device protective case 6 provided in a sixth embodiment of the present invention differs from the electronic device protective case 1 provided in the first embodiment in that a card holder 116 is further provided on the side of the background plate 11 facing away from the bottom plate 102 .

[0113] It can be understood that the card holder 116 forms a space that can be used to place items such as documents.

[0114] Please refer to Figure 12. An electronic device protective case 7 provided in a seventh embodiment of the present invention is different from the electronic device protective case 1 provided in the first embodiment in that: the electronic device protective case according to claim 1 is characterized in that: a charging and discharging module 117 is provided on the background plate 11.

[0115] It can be understood that the charging and discharging module 117 can be an energy storage battery, which can be used as an emergency power supply to charge electronic devices, etc., which is equivalent to being used as a power bank.

[0116] 1 and 13-14 , the eighth embodiment of the present invention further provides a background plate 11 for installation on any electronic device protective case as described in the previous embodiments.

[0117] A magnetic element 113 is provided on the background plate 11, wherein the magnetic element 113 may also be a magnet or a material that is magnetically attracted to a magnet; as an optional embodiment, the background plate 11 may be a two-layer structure, wherein the layer close to the bottom plate 102 is the magnetic element 113, which is a magnet or a material that is magnetically attracted to a magnet, and the other layer is used to set the background appearance such as patterns and shapes.

[0118] As a preferred solution, the magnetic element 113 is a ring-shaped magnet. When wireless charging is used to charge the mobile phone, the ring-shaped magnetic element can assist in charging and speed up the charging efficiency. Moreover, the ring-shaped magnet can automatically correct its relative position with the wireless charging coil so that it is just facing the charging area, which is convenient for quick positioning and wireless charging.

[0119] The area surrounded by the magnetic element 113 is a charging area, and the electronic device is charged in the charging area.

[0120] Furthermore, an external lens hole 111 is provided on the background board 11, and a lens frame 12 is provided at the external lens hole 111. The lens frame 12 includes a guard eave 121 located on one side of the background board 11 and extending to the surrounding areas; the separation structure is at least one notch 123 or at least two oppositely arranged notches 123 opened on the guard eave 121.

[0121] Specifically, the eaves 121 are located on the side of the background plate 11 away from the bottom plate 102 .

[0122] Among them, in this embodiment, the notch 123 is set on the outer peripheral side of the eaves 121. The notch can be at the bottom, middle, or upper part of the outer peripheral side for hand buckles to facilitate pulling the background plate away from the bottom plate, thereby making it easy to replace the background plate.

[0123] In addition, an opening is provided on the eaves 121, so that when removing the background plate 11, you can directly hold the notch 123 to remove the background plate 11 and the lens frame 12 together, reducing the number of operating steps, and then the background plate 11 and the lens frame 12 can be separated through the notch 123.

[0124] Furthermore, the lens frame 12 is detachably connected to the outer lens hole 111. It can be understood that when the user replaces the desired background plate 11, he or she can simply choose to replace the background plate 11 and retain the lens frame 12, thereby saving costs.

[0125] In other embodiments, the lens frame is rotatably connected to the background plate. It is understood that when the lens protection frame 115 is open, it can serve as a bracket to support the electronic device, and also as a separation structure to separate the background plate from the electronic device protective case; when closed, it is used to protect the camera on the electronic device.

[0126] The lens frame 12 also includes a snap-on portion 122, which is located on the side of the eaves 121 close to the background board 11. The snap-on portion 122 is provided with at least one protrusion 124, and a slot 125 is formed between the protrusion 124 and the eaves 121; when the lens frame 12 is connected to the background board 11, the inner wall of the outer lens hole 111 is snapped into the slot 125.

[0127] It can be understood that the card slot 125 formed between the protrusion 124 and the eaves 121 is used to clamp the edge position of the background board 11, so that the clamping is more secure, making it difficult for the lens frame 12 to fall off. When disassembling the lens frame 12, you only need to use the notch 123 to pick out the lens frame 12.

[0128] In other embodiments, the separation structure may also be a bracket rotatably connected to one side of the background plate 11 .

[0129] The bracket is arranged on a side away from the bottom plate 102. It can be understood that the bracket 114 can be stored or opened. When the bracket 114 is opened, it can support the electronic device. In addition, the bracket can also be used as a handle to pull and remove the background plate 11.

[0130] Furthermore, the width of the slot matches the thickness of the background plate, so that the connection between the lens frame 12 and the background plate 11 is more secure and tight, preventing the lens frame 12 from shaking and preventing dust from entering.

[0131] Compared with the prior art, the background board and electronic device protective case provided by the present invention have the following advantages:

[0132] 1. The background board provided in the embodiment of the present invention has an external lens hole, and a lens frame is provided at the external lens hole; the lens frame includes an eaves located on the side of the background board away from the bottom plate and extending in all directions, the eaves is close to one side of the background board and has at least one notch at the edge of the eaves; by directly snapping the lens frame onto the detachable background board, when removing the background board, only a handle formed by the notch is needed, and the user can complete the removal of the background board by holding it with his hand, and the notch is not obvious and does not affect the aesthetic level of the appearance. In addition, when the background board is installed on the protective case of the electronic device, the handle can also be used to remove the background board.

[0133] 2. An embodiment of the present invention also provides a protective case for an electronic device, in which a side of the bottom plate facing away from the accommodating groove is enclosed with the frame to form a limiting groove. It can be understood that by providing the limiting groove to accommodate the background plate, the feel of the protective case can be maintained better, and the background plate will not protrude, thereby affecting the user experience. At the same time, the limiting groove also limits the translation of the background plate.

[0134] 3. An embodiment of the present invention also provides a protective case for an electronic device. Since the lens frame is clamped on a detachable background plate, after the background plate is connected to the base plate, the second clamping block on the lens frame also cooperates with the first clamping block on the base plate to further limit the background plate, so that the background plate can be firmly and tightly connected to the base plate at the lens frame, and dust is not easily ingressed.
