DETAILED DESCRIPTION
[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the embodiments of the utility model will be described clearly and completely below in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.
[0030] All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the utility model without creative labor fall within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the disclosure should be understood as the usual meaning by those of ordinary skill in the art to which the utility model belongs.

Similarly, "one", "an" or "the" and similar words do not represent a quantity limit, but represent the existence of at least one. "Include" or "contain" and similar words mean that the elements or objects before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connected" or "connected" and similar words are not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0032] Referring to the drawings Figures 1-3 , an electric suction disc mobile phone shell is shown, the mobile phone shell 1 includes a main shell 2, an electric suction disc 3, the main shell 2 has a back plate 20 and a side wall 21, the side wall 21 extends from the edge of the back plate 20 to the front side, the side wall 21 and the back plate 20 form a containing cavity 22, and the front side of the containing cavity 22 forms a cavity opening; the electric suction disc 3 is installed on the back side of the back plate 20.
[0033] The material of the main shell 2 can be plastic or metal, etc., which has certain deformation capacity, when the mobile phone is put into the containing cavity 22 from the cavity opening, the main shell 2 deforms slightly, so that the mobile phone can be put into the containing cavity 22 more smoothly, and the mobile phone is stabilized in the cavity by the wrapping property of the main shell 2.
[0034] The electric suction disc 3 provides suction force for the mobile phone shell 1, and the mobile phone shell 1 can be stably adsorbed on the wall or other objects through the electric suction disc 3. In the kitchen, bathroom or other environment with water and oil fume, the suction disc 32 can be adsorbed on the adsorption surface such as wall, and the position of the mobile phone shell 1 can be adjusted at any time, without damaging the adsorption surface or leaving marks, and the electric suction disc 3 can be repeatedly used, and the adsorption stability will not rapidly decrease, and the stability of the mobile phone shell 1 can be ensured after repeated use.
[0035] Preferably, the bottom surface of the accommodating cavity 22 can be provided with a flexible protection piece 23. For example, a plurality of sponge pads are bonded to the bottom surface of the accommodating cavity 22, and when the mobile phone is embedded in the accommodating cavity 22, the sponge pads can provide protection function, avoiding excessive friction between the mobile phone and the main shell 2, and damaging the appearance of the mobile phone.
[0036] If the cavity opening of the main shell 2 is not capped, in order to ensure the stability of the mobile phone, the accommodating cavity 22 needs to be matched with the shape of the mobile phone at this time, and the mobile phone is stably placed in the cavity by the wrapping of the main shell 2. In this case, the accommodating cavity 22 can only match the mobile phone of the corresponding model, which limits the universality of the mobile phone shell 1.
[0037] Therefore, in the embodiment, a flip cover is configured for the main shell 2, the flip cover is installed on the front side of the main shell 2, and the cavity opening is opened or closed by operating the flip cover, and the flip cover has a viewing window matched with the cavity opening. When the flip cover is closed on the front side of the main shell 2, the cavity opening is closed, and the mobile phone placed in the accommodating cavity 22 will not fall off, and the user can watch the screen of the mobile phone through the viewing window.
[0038] The cavity opening of the accommodating cavity 22 is closed by the flip cover to form a closed space, and the mobile phone will not fall off at will, so that the shape of the accommodating cavity 22 does not need to be matched with a certain specific model of mobile phone, and only needs to have enough space to accommodate the mobile phone, so that it has universality. The cover can also protect the mobile phone from water and dust, which is conducive to the use of the mobile phone shell 1 in bathroom, kitchen and other application scenarios.
[0039] In order to form a flip cover with a viewing window, there are various forms. For example, the flip cover is matched with the profile of the main shell 2, so as to be closed on the front side of the main shell 2, and the middle region of the flip cover is hollowed out to form a viewing window matched with the screen of the mobile phone. For another example, the flip cover includes a cover frame 4, the cover frame 4 is closed on the outer periphery of the side wall of the main shell 2, a window for observation is arranged in the middle of the cover frame 4, the window corresponds to the cavity opening of the accommodating cavity 22, a transparent plate 40 is installed in the window, the transparent plate 40 is made of resin and is bonded and fixed with the edge of the window, so as to form a viewing window.
[0040] The cover can be tightly fitted to the front side of the main shell 2, and the user can directly apply force to open the cover. Alternatively, a buckle structure can be arranged between the cover and the main shell 2, and the user can open the cover after disengaging the buckle.
[0041] In this embodiment, the following arrangement is adopted: one side of the cover is rotationally connected to the main shell 2, and the cover is rotated along the one side to open and close the cavity opening; the other side of the cover is provided with a matching locking mechanism 5 with the main shell 2.
[0042] Specifically, taking the square main shell 2 shown in the drawings as an example, the bottom side of the cover is rotationally connected to the bottom side of the main shell 2, and the rotational connection portions of the two are provided with matching shafts and shaft holes. The top of the cover is provided with the locking mechanism 5 with the top of the main shell 2. When the cover is closed with the main shell 2, the locking mechanism 5 is operated to be in the locked state, so as to ensure the stability of the closing effect. When the cover needs to be opened, the locking mechanism 5 is unlocked, and the cover is folded to rotate outward along the rotational connection portion with the main shell 2, so that the cavity opening is exposed and opened. After the cover is opened, it is still connected to the main shell 2 as a whole through the rotational connection portion, so the user does not need to hold the cover, which reduces the occupation of the hand and facilitates the operation of taking and placing the mobile phone.
[0043] The locking mechanism 5 is used to lock the cover with the main shell 2, and includes two parts. One part is arranged on the main shell 2 and includes a button 50, a compression spring 51 and a hook 501. The other part is arranged on the cover and includes a hook groove. The hook 501 is connected with the button 50 and moves synchronously with the button 50 under the control of the button 50. The compression spring 51 acts on the button 50, and the elastic force of the compression spring 51 drives the button 50 to move the hook 501, so that the hook 501 is locked with the hook groove, and the cover is locked with the main shell 2 at this time. When the button 50 is pressed, the button 50 is forced and drives the hook 501 to move away from the hook groove, so that the lock between the two is released, and the cover is unlocked with the main shell 2 at this time, and the cover can be opened by rotating along one side.
[0044] Specifically, a groove 24 is formed on the side wall of the main shell 2, for example, the groove 24 is formed on the side wall of the top of the main shell 2. The top of the groove 24 has an opening, and the upper part of the button 50 is exposed through the opening for the user to operate. The lower part of the button 50 is installed in the groove 24, and the assembly mode between the two ensures that the button 50 is installed in the groove 24, and also enables the button 50 to be lifted and lowered within a certain range compared with the groove 24. The compression spring 51 is longitudinally arranged between the button 50 and the main shell 2 in the groove 24. The hook 501 is arranged on the front side wall of the button 50, and the hook 501 has a hook tail 502 extending upward. The hook groove has a slot opening downward to match the hook tail 502 to enter and exit.
[0045] In normal state, the button 50 is held upward by the compression spring 51, driving the catch 501 upward and entering the hook slot through the slot, and the two are locked; the button 50 is pressed to drive the catch 501 downward, and the hook tail 502 of the catch 501 is separated downward from the hook slot through the slot, and the two are unlocked, at this time the compression spring 51 is in a force storage state, and after the external force is removed, it rebounds and resets, and the button 50 and the catch 501 are reset to the locked state again.
[0046] Referring to the drawings Figures 4-5 , two embodiments of the lock mechanism 5 are shown.
[0047] In the first embodiment, a stroke slot 240 is formed along the inner wall of the slot body 24, and the lower part of the button 50 extends horizontally to form a stroke block 503, which is adapted to the stroke slot to limit the button 50 in the slot body 24 and can move up and down within a certain longitudinal range.
[0048] The stroke slot 240 in the slot body 24 can be formed around its circumference at this time, and the stroke block 503 can be a lug (partially horizontally extended from the lower edge of the button 50) or a skirt (horizontally extended from the lower edge of the button 50), and the height of the stroke slot 240 is greater than the thickness of the stroke block 503, so that the stroke block 503 has a certain up and down movement range in the stroke slot 240. When the button 50 goes up, the stroke block 503 goes up in the stroke slot 240, and when it reaches the top end of the stroke slot 240, it is limited, preventing the button 50 from going up and out of the slot body 24.
[0049] The stroke slot 240 in the slot body 24 can be longitudinally extended, and the stroke slot 240 can be two or more, evenly spaced around the inner wall of the slot body 24, and the stroke block 503 is a corresponding number of lugs, each lug is extended into a stroke slot 240, and the longitudinal length of the stroke slot 240 determines the up and down movement range of the button 50. When the button 50 goes up to the lug and the top end of the stroke slot 240, the upstroke of the button 50 is completed and is limited by the end wall of the stroke slot 240, preventing it from escaping from the opening at the top of the slot body 24.
[0050] In the second embodiment, the lower part of the button 50 is connected with an extension foot 504, the side wall of the main shell 2 is provided with a small hole, the extension foot 504 passes downward through the small hole, the extension foot 504 can move up and down along the small hole, and the bottom end of the extension foot 504 is provided with a limiting block 505 to prevent the extension foot 504 from escaping from the small hole.
[0051] The number of the extension legs 504 is preferably two or more, and they are distributed evenly below the key 50 to ensure the balance of the lifting movement of the key 50. Correspondingly, a plurality of small holes are formed in the sidewall of the bottom of the groove body 24, i.e. the top of the main shell 2, and the diameter of the small holes is slightly larger than the diameter of the extension legs 504, so that the extension legs 504 are lifted synchronously in the corresponding small holes when the key 50 is lifted. The limiting block 505 at the bottom end of the extension leg 504 has a size larger than the small hole, and when the key 50 is lifted to the locked state of the hook 501 and the hook groove, the limiting block 505 abuts against the bottom surface of the small hole, thereby limiting the key 50 through the extension leg 504, avoiding the key 50 from being lifted out of the groove body 24.
[0052] Referring to the drawings Figures 6-10 The electric suction disc 3 on the electric suction disc mobile phone shell comprises an outer shell 30, a suction disc 32, a suction system 31 and a power supply module; the outer shell 30 is fixed with the back plate 20; the suction disc 32 is installed on the rear side of the outer shell 30, and the side of the suction disc 32 away from the outer shell 30 has a suction cavity, and the rear end of the suction cavity has an opening; the suction system 31 and the power supply module are installed in the outer shell 30, the suction system 31 is communicated with the suction cavity to adjust the air pressure of the suction cavity and control the suction state of the suction disc 32 and external objects; and the power supply module is electrically connected with the suction system 31 to supply power for the same.
[0053] The outer shell 30 is fixed on the rear side of the back plate 20 to form an installation space therebetween for installing the suction system 31, the power supply module and other structures. The suction system 31 comprises an air pump 210, an air pipe and a pressure relief member, the air pump 210 and the pressure relief member are communicated with the suction cavity through the air pipe, the air pump 210 controls the air pipe to extract air to make the suction cavity in a negative pressure state, and the suction disc 32 has a suction force to be adsorbed on a wall or other adsorption surface through the opening at the rear end.
[0054] The pressure relief member controls the air pipe to communicate the suction cavity with the external environment, balances the air pressure of the suction cavity and the external environment, eliminates the negative pressure environment of the suction cavity and releases the suction force of the suction disc 32. The pressure relief member comprises a pressure relief valve 311 and a pressure relief switch 312, the pressure relief valve 311 is built in the outer shell 30 and communicated with the suction cavity through the air pipe, and the pressure relief switch 312 is connected with the pressure relief valve 311 and exposed outside the outer shell 30 to be operated by a user to start the pressure relief valve 311.
[0055] The power supply module provides electric energy for the suction system 31, which preferably adopts an energy storage battery and is provided with a charging port to charge the energy storage battery. In this way, the mobile phone shell 1 can be used without being limited by a wire body, and the use is more flexible and convenient.
[0056] In some embodiments, the suction system 31 is configured with a starting assembly arranged in the suction cavity and in signal communication with the suction system 31; the starting assembly detects the distance between the suction cup 32 and the suction surface of the external object to start the suction system 31 to perform suction when the suction cup 32 is adsorbed to the external object.
[0057] When the mobile phone shell 1 is used, the opening of the suction cup 32 is aligned and attached to the suction surface, the starting assembly detects the distance between the suction cup 32 and the external object, feeds back the working signal to the suction system 31, the suction system 31 starts the air pump 210 to extract the air in the suction cavity, so that the cavity is in a negative pressure state, and the suction cup 32 generates strong suction force to be adsorbed to the external object.
[0058] In some embodiments, the housing 30 is provided with an air chamber 33, the housing 30 and the suction cup 32 are provided with corresponding through hole parts 35, the suction system 31 is communicated with the suction cavity through the air chamber 33 and the through hole part 35; the starting assembly includes a starting piece 34 and a sensor, one end of the starting piece 34 is arranged in the air chamber 33, the other end of the starting piece 34 reaches the suction cavity through the through hole part 35; the sensor is responsive to the starting piece 34 and is electrically connected with the suction system 31; when the suction cup 32 is adsorbed to the external object, the starting piece 34 is triggered, the sensor is responsive and starts the suction system 31 to extract the suction cavity to a negative pressure state.
[0059] Specifically, the bottom surface of the housing 30 is protruded to form a first convex rib 331 and a second convex rib 332, the first convex rib 331 surrounds the periphery of the second convex rib 332, and a spacing area is formed between the two, and a cover plate 333 is sealed above the first convex rib 331 and the second convex rib 332 to enclose the spacing area to form the air chamber 33. On the bottom surface of the housing 30 and inside the periphery of the second convex rib 332, a first through hole is formed, and a second through hole is formed on the suction cup 32, the two through holes correspond and communicate to constitute the through hole part 35.
[0060] The starting piece 34 includes a column 340 and a cap 341, one end of the column 340 passes downward through the first through hole and the second through hole to reach the suction cavity, and there is an air flow gap between the column 340 and the first through hole and the second through hole, and the other end of the column 340 is connected with the cap 341, the cap 341 has a ring groove 342, and the second convex rib 332 is embedded in the ring groove 342. A gas hole 3320 is formed on the second convex rib 332, which communicates the air chamber 33 and the through hole part 35, and the cap 341 is provided with a gas groove corresponding to the gas hole 3320, so that the one end of the gas hole 3320 corresponding to the air chamber 33 always maintains a communication state, and the other end of the gas hole 3320 away from the air chamber 33 is blocked by the side wall of the ring groove 342.
[0061] When the suction cup 32 is adsorbed to the external object, the external object generates a resisting force to the column 340, so that the cap 341 is deformed towards the shell 30, the side wall of the ring groove 342 deviates from the end of the air hole 3320 away from the air chamber 33, so that the air hole 3320 is open, and the air chamber 33 is communicated with the adsorption cavity through the air hole 3320 and the through hole part 35. At the same time, the external object activates the piece 34, and sends a signal to the suction system 31, and the suction system 31 works to extract the air in the adsorption cavity, so that it is in a negative pressure adsorption state.
[0062] The sensor can be a pressure switch, a mechanical switch, etc., installed in the cavity at the top of the cap 341, and the sensor is a certain distance from the activating piece 34. When the suction cup 32 is adsorbed on the external object, the column 340 moves into the shell 30, and the center position of the cap 341 is lifted to press the sensor, so that it sends a signal to the suction system 31.
[0063] The sensor can also be a gas pressure or gas sensitive element, which is arranged in the cavity at the top of the cap 341. When the column 340 is pressed to deform the cap, the airflow or air pressure near the sensor changes, which generates a feedback signal to the suction system 31, and the suction system 31 starts to work.
[0064] In summary, the improved electric suction cup 3 mobile phone shell 1 at least includes a main shell 2 and an electric suction cup 3. The mobile phone is accommodated by the main shell 2, and the mobile phone shell 1 and the external object are adsorbed and fixed by the electric suction cup 3. The structure of the suction cup is used to fix the mobile phone shell 1, which is convenient for flexible adjustment of the position of the mobile phone shell 1, and will not damage the adsorption surface. At the same time, after multiple uses, the adsorption force effect is still stable and reliable, which can ensure the stability of the installation of the mobile phone shell 1.
