Technical Field

[0001] The present application belongs to the technical field of protection of electronic equipment, and specifically relates to a protective cover and an electronic equipment component. Background Art

[0002] In the related art, foldable screen mobile phones are getting thinner and thinner, resulting in a smaller internal thickness space and a smaller water drop shape of the main screen. When in use, one side of the hinge cover of the mobile phone falls to the ground, which can easily damage the main screen. Moreover, after long-term use, sand, dust, sweat, etc. can easily enter the mobile phone from the gap between the hinge cover and the middle frame of the mobile phone, causing corrosion and damage to the flexible printed circuit (FPC), and then the FPC is broken, causing the mobile phone to fail. At present, in order to protect the main screen and the flexible circuit board, a protective case is added for the whole machine. However, when the foldable screen mobile phone is unfolded, the protective case will also unfold and slide on the secondary screen, and there is a risk that the secondary screen is easily scratched. Summary of the invention

[0003] The present application aims to provide a protective cover that at least solves the problem of preventing the secondary screen from being easily scratched.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0026] Combine the following Figure 1 - Fig. 9 The protective cover 10 of the embodiment of the present application is described. The protective cover 10 in the embodiment of the present application can be used to protect an electronic device 80. The electronic device 80 can be a folding screen mobile phone or a folding screen tablet. The electronic device 80 includes a first device body 81, a second device body 82 and a hinge assembly 85. The first device body 81 and the second device body 82 can be rotatably connected by the hinge assembly 85, so that the electronic device 80 can be switched between a folded state and an unfolded state. Figures 1 to 3 As shown, when the electronic device 80 is in the folded state, the first device body 81 and the second device body 82 are stacked, and when the electronic device 80 is in the unfolded state, the first device body 81 and the second device body 82 are laid side by side.

[0027] Specifically, a first display screen 83 is disposed on a first side of the first device body 81 and the second device body 82, and the first display screen 83 is a main screen of the electronic device 80. A second display screen 84 is disposed on a second side of the second device body 82, and the second display screen 84 is a secondary screen of the electronic device 80. The first side and the second side are opposite to each other. When the electronic device 80 is in the folded state, the second display screen 84 can be used for display, and when the electronic device 80 is in the unfolded state, the first display screen 83 can be used for display.

[0028] Furthermore, in order to protect the first display screen 83, a main screen protection film may be attached to the first display screen 83. In order to protect the second display screen 84, a secondary screen protection film may be attached to the second display screen 84.

[0029] like Figures 4 to 6 As shown, according to some embodiments of the protective cover 10 of the present invention, the protective cover 10 includes: a main body 1 and a rotating part 2, the main body 1 and the rotating part 2 can be rotatably connected, when the protective cover 10 is installed on the electronic device 80, the main body 1 can be sleeved on the outside of the first device body 81, and the rotating part 2 can be sleeved on the outside of the hinge assembly 85; a protective member is provided on the edge of the rotating part 2 away from the main body 1, and the protective member is in contact with the second display screen 84 during the unfolding and folding process of the electronic device 80.

[0030] In the embodiment of the present application, the main body 1 and the rotating part 2 can be rotatably connected, so that when the electronic device 80 is folded, the rotating part 2 can be folded relative to the main body 1, and when the electronic device 80 is unfolded, the rotating part 2 can be unfolded relative to the main body 1. The main body 1 is sleeved on the outside of the first device body 81 to protect the first device body 81. When the electronic device 80 is folded, the rotating part 2 can cover the hinge assembly 85. When the electronic device 80 falls, the rotating part 2 can buffer the impact force to prevent the hinge assembly 85 from being directly deformed by force and squeezing the first display screen 83 of the electronic device 80. In addition, it can prevent sand, dust, sweat, etc. from entering the interior of the electronic device 80 from the gap at the hinge assembly 85, and prevent the FPC of the electronic device 80 from being corroded and damaged, thereby ensuring the function of the electronic device 80. In addition, a protective member is provided on the edge of the rotating part 2 away from the main body 1. During the process of unfolding and folding the electronic device 80, the protective member can contact the second display screen 84, so that the protective member can protect the second display screen 84 and prevent the second display screen 84 from being scratched.

[0031] In the embodiment of the present application, the protective cover 10 can be assembled with the electronic device 80, and the protective cover 10 can be deformed along with the deformation of the electronic device 80. Since the main body 1 is assembled with the first device body 81, the main body 1 can be fixed relative to the first device body 81, so that when the second device body 82 is unfolded relative to the first device body 81, the rotating part 2 is driven to unfold relative to the main body 1, and when the second device body 82 is folded relative to the first device body 81, the rotating part 2 is driven to fold relative to the main body 1.

[0032] Furthermore, when the electronic device 80 is in a folded state, the rotating part 2 can be folded relative to the main body 1, and the rotating part 2 can cover the hinge assembly 85. On the one hand, it can cover the gap where the hinge cover 851 is located, and can prevent sand, dust, sweat, etc. from entering the interior of the electronic device 80 through the gap where the hinge assembly 85 is located, thereby preventing sand, dust, sweat, etc. from corroding and damaging the FPC of the electronic device 80, saving after-sales costs, and greatly improving product quality and user experience. On the other hand, the rotating part 2 can buffer the impact force and prevent the hinge assembly 85 from deforming and squeezing the first display screen 83, thereby ensuring the product quality and user experience of the electronic device 80.

[0033] Specifically, when the electronic device 80 is in the unfolded state, the rotating portion 2 can cover at least a portion of the second display screen 84. In this case, when the electronic device 80 falls or is hit, a portion of the second display screen 84 can also be protected.

[0034] Specifically, the main body 1 and the rotating part 2 may have a certain structural strength to better protect the body. For example, the main body 1 and the rotating part 2 may be made of plastic, rubber or silicone.

[0035] In some embodiments, the main body 1 and the rotating part 2 can be connected by a transition part 3, which serves to connect the main body 1 and the rotating part 2. The transition part 3 can be deformed. For example, the transition part 3 can be a flexible part or a shape memory part. Under the deformation function of the transition part 3, the rotating part 2 can be folded or unfolded relative to the main body 1.

[0036] Specifically, the main body 1, the rotating part 2 and the adapter part 3 can be an integrally formed structure, or can be spliced ​​and fixed by means of snap connection, bonding, etc., and the embodiments of the present application do not make specific limitations on this.

[0037] Specifically, the main body 1 can be snap-fitted with the first device body 81, and the shape of the main body 1 can be adapted to the first device body 81. The specific shape and size of the main body 1 can be designed with reference to the shape and size of the first device body 81, and the embodiment of the present application does not specifically limit this. The shape of the rotating part 2 can be adapted to the shape of the hinge assembly 85, and the shape and size of the rotating part 2 can be designed with reference to the hinge assembly 85, and the embodiment of the present application does not specifically limit this.

[0038] Furthermore, since a protective member is provided on the side of the rotating part 2 away from the main body 1, the protective member can contact the second display screen 84 during the process of the rotating part 2 being folded or unfolded relative to the main body 1, thereby reducing friction on the second display screen 84 and thus avoiding damage to the second display screen 84. When a secondary screen protective film is attached to the second display screen 84, the protective member can contact the secondary screen protective film, thereby reducing friction between the protective member and the secondary screen protective film and avoiding scratches or scratches on the secondary screen protective film.

[0039] In some optional embodiments, Fig. 9 As shown, the protective member may include a flexible contact member 42 , and the flexible contact member 42 may be protrudingly disposed at an edge of the rotating portion 2 facing the second display screen 84 .

[0040] In the embodiment of the present application, during the unfolding and folding process of the electronic device 80, the flexible contact member 42 can directly contact the second display screen 84, and the hardness of the flexible contact member 42 can be less than the surface hardness of the second display screen 84. When the flexible contact member 42 contacts the second display screen 84, the second display screen 84 can be prevented from being scratched or scratched.

[0041] Optionally, the flexible contact member 42 may be an elastic rubber structure, which can effectively ensure the flexibility of the flexible contact member 42 and improve the protection effect on the second display screen 84 .

[0042] Specifically, the flexible contact member 42 can be made of soft rubber materials such as polypropylene (PP), polyethylene (PE), and thermoplastic polyurethanes (TPU).

[0043] In some other optional embodiments, Figure 8 As shown, the protective member may include a roller assembly 41, and the roller assembly 41 may include a roller 411 and a roller shaft. A limiting groove 21 is provided on the side of the rotating portion 2 away from the main body 1, and the roller 411 is rotatably connected to the groove wall of the limiting groove 21 through a rotating shaft 412; during the unfolding and folding process of the electronic device 80, the roller 411 can roll along the second display screen 84, effectively reducing the friction between the protective member and the second display screen 84, and preventing the second display screen 84 from being scratched.

[0044] Specifically, at least a portion of the roller 411 may protrude from the rotating portion 2 , so that only the roller 411 may contact the second display screen 84 , thereby greatly reducing the risk of the rotating portion 2 scratching the second display screen 84 .

[0045] Specifically, the number of rollers 411 may be two, three or four, etc., which is not specifically limited in the present embodiment. At least two rollers 411 may be spaced apart along the length direction of the rotating portion 2, and in some cases, the rollers 411 may also contact the frame of the second device body 82, which is not specifically limited in the present embodiment.

[0046] Specifically, the roller 411 may be fixedly connected to the rotating part 2, or the roller 411 may be movably connected to the rotating part 2. When the roller 411 is fixedly connected to the rotating part 2, the roller 411 may slide relative to the second display screen 84; when the roller 411 is movably connected to the rotating part 2, the roller 411 may roll relative to the second display screen 84.

[0047] In the embodiments of the present application, Figure 7 As shown, partially embedding the roller 411 in the limiting groove 21 can improve the convenience of arranging the rotating shaft 412, thereby improving the reliability of realizing the movement of the roller 411.

[0048] Specifically, Figure 7 As shown, a limiting groove 21 is dug on one side of the rotating part 2 away from the main body 1 , and part of the roller 411 is embedded in the limiting groove 21 , so that the two ends of the rotating shaft 412 are respectively connected to the rotating part 2 after passing through the roller 411 .

[0049] Specifically, Figure 8As shown, when the roller 411 rotates clockwise, the rotating part 2 is driven to unfold relative to the main body 1 ; when the roller 411 rotates counterclockwise, the rotating part 2 is driven to fold relative to the main body 1 .

[0050] Specifically, the rotating shaft 412 can be fixedly connected to the rotating part 2, and the roller 411 can roll around the rotating shaft 412. Alternatively, the rotating shaft 412 can be fixedly connected to the roller 411, and both ends of the rotating shaft 412 can be rotatably connected to the rotating part 2 respectively.

[0051] Specifically, part of the roller 411 is embedded in the limiting groove 21 , and the other part may be located outside the limiting groove 21 and in contact with the second display screen 84 .

[0052] In some optional embodiments, the number of the roller assemblies 41 includes two, and the two roller assemblies 41 are symmetrically arranged at two ends of the rotating part 2 .

[0053] In the embodiment of the present application, two roller assemblies 41 are symmetrically arranged at both ends of the rotating part 2, so that the two ends of the rotating part 2 are subjected to force in a relatively balanced manner, thereby ensuring the reliability and stability of the rotating part 2 when folding or unfolding relative to the main body 1.

[0054] Specifically, the two roller assemblies 41 can be respectively arranged at the two ends of the rotating part 2 along the length direction thereof. In this case, the roller 411 in the roller assembly 41 can roll relative to the frame of the second device body 82, that is, the roller 411 can contact the frame of the second device body 82, and the roller 411 does not contact the second display screen 84, which can further avoid the probability of the second display screen 84 being damaged or broken, and ensure the quality of the electronic device 80 displayed through the second display screen 84.

[0055] In other embodiments, the roller assembly 41 may also be located in the middle of the rotating portion 2 along its length direction, so that the roller 411 rolls on the second display screen 84 .

[0056] Optionally, a side of the rotating portion 2 away from the main body 1 is provided with an escape space 22 , and the escape space 22 is located between the two roller assemblies 41 .

[0057] In the embodiment of the present application, an avoidance space 22 is provided on the rotating part 2 , which can further reduce the probability of the rotating part 2 contacting the second display screen 84 , and thus the probability of the rotating part 2 scratching the second display screen 84 .

[0058] Specifically, the middle part of the side of the rotating part 2 away from the main body 1 can be partially hollowed out to form an escape space 22, so that even if the rotating part 2 is squeezed and deformed to a certain extent, it is not easy to contact the second display screen 84, which can reduce the probability of the rotating part 2 scratching the second display screen 84, and facilitate ensuring the quality of the second display screen 84. The depth of the escape space 22 can be designed according to actual needs, and is not specifically limited in the embodiments of the present application.

[0059] In some optional embodiments, the protective cover 10 further includes a protective member 6 , which is filled in the avoidance space 22 and connected to the rotating part 2 .

[0060] In the embodiment of the present application, the protective member 6 is filled in the avoidance space 22. In this way, when the rotating part 2 is subjected to pressure and causes a large deformation, the protective member 6 can contact the second display screen 84 or the secondary screen protective film. The protective member 6 directly contacts the second display screen 84 or the secondary screen protective film to generate sliding friction. The protective member 6 is not easy to scratch the second display screen 84 or the secondary screen protective film, thereby protecting the second display screen 84 or the secondary screen protective film.

[0061] Specifically, when the middle of the rotating part 2 is deformed by force and concave, the protective part 6 can directly contact the second display screen 84 or the secondary screen protective film, and the protective part 6 and the second display screen 84 or the secondary screen protective film generate sliding friction. The material of the protective part 6 can be polypropylene (Polypropylene, PP), polyethylene (polyethylene, PE), thermoplastic polyurethane elastomer rubber (Thermoplasticpolyurethanes, TPU) and other soft rubber materials. The hardness of the protective part 6 is much smaller than the surface hardness of the second display screen 84 or the secondary screen protective film. The second display screen 84 or the secondary screen protective film is not easily scratched or scratched by the protective part 6, and the second display screen 84 or the secondary screen protective film can be effectively protected.

[0062] Specifically, the protective member 6 may be fixedly connected to the rotating part 2 by bonding, or the protective member 6 may be integrally formed with the rotating part 2 by injection molding.

[0063] Specifically, the protective member 6 may completely fill the avoidance space 22, or a layer of the protective member 6 may be coated on the side wall of the avoidance space 22. The amount of the protective member 6 used in the embodiment of the present application is not specifically limited.

[0064] Optionally, the main body 1 has a first accommodating groove 11, which is used to accommodate the first device body 81; the rotating part 2 has a second accommodating groove 23, which is used to accommodate the hinge assembly 85; the notches of the first accommodating groove 11 and the second accommodating groove 23 are oriented in the same direction.

[0065] In the embodiment of the present application, the first device body 81 is placed in the first receiving groove 11, which, on the one hand, facilitates the first device body 81 to be clamped and fixed to the main body 1, and on the other hand, facilitates the main body 1 to provide good protection for the first device body 81. The hinge assembly 85 is embedded in the second receiving groove 23, which facilitates the hinge assembly 85 to be protected by the rotating part 2, and facilitates the rotating part 2 to cover the gap where the hinge assembly 85 is located.

[0066] Specifically, the first device body 81 is placed in the first accommodating groove 11 so that the first device body 81 is relatively fixed to the main body 1. When the electronic device 80 is switched to the unfolded state, the rotating part 2 is unfolded together with the second device body 82, the hinge assembly 85 is hidden, and the rotating part 2 covers at least part of the second display screen 84; when the electronic device 80 is switched to the folded state, the rotating part 2 is folded together with the second device body 82, the hinge assembly 85 appears and can be inserted into the second accommodating groove 23, so that the rotating part 2 can provide good protection for the hinge assembly 85.

[0067] Optionally, the protective cover 10 further includes a magnetic component, which is disposed on the rotating portion 2 , and specifically can be disposed at the bottom of the second accommodating groove 23 , and the magnetic component can be magnetically connected to the hinge assembly 85 .

[0068] In the embodiment of the present application, the magnetic member is magnetically attracted to the hinge assembly 85 , so that the rotating part 2 can be closely attached to the hinge assembly 85 , so as to better protect the hinge assembly 85 .

[0069] Specifically, the hinge assembly 85 includes a hinge and a hinge cover 851. The hinge cover 851 can be hinged to the first device body 81 and the second device body 82 respectively. The hinge cover 851 covers the hinge to protect the hinge. When the electronic device 80 is in a folded state, the rotating part 2 can cover the hinge cover 851. In this case, when the electronic device 80 falls, the rotating part 2 can buffer the force to prevent the hinge cover 851 from squeezing the first display screen 83, thereby preventing the first display screen 83 from being damaged.

[0070] Specifically, when the electronic device 80 is in a folded state, the rotating part 2 is folded relative to the main body 1, and the magnetic part is magnetically attracted to the hinge assembly 85, so that the rotating part 2 and the hinge assembly 85 fit tightly, which has a better protection effect on the hinge assembly 85, and can better cover the gap between the hinge cover 851 and the first device body 81 or the second device body 82, preventing sand, dust and liquid from entering the interior of the mobile phone to corrode and damage the FPC.

[0071] Specifically, the magnetic member may be a magnet or a permanent magnet.

[0072] Specifically, when the electronic device 80 is in a folded state, the magnetic part and the hinge assembly 85 can be used to form a magnetic attraction so that the rotating part 2 is in close contact with the hinge cover 851; when the electronic device 80 is in an unfolded state, the adapter part 3 can be deformed, and the resilience of the adapter part 3 can be used to make the rotating part 2 in close contact with the second device body 82.

[0073] Specifically, the hinge assembly 85 may further include a magnetic portion 852 , which may be connected to the hinge cover 851 , and the magnetic portion 852 on the hinge cover 851 may be magnetically attracted to the magnetic part on the rotating portion 2 to improve the reliability and stability of the close fit between the rotating portion 2 and the hinge assembly 85 .

[0074] In some further optional embodiments, the protective cover 10 further includes a protective frame 5 , which is sleeved on the outer side of the second device body 82 to protect the second device body 82 and reduce the probability of damage to the second device body 82 .

[0075] Specifically, the roller 411 or the flexible contact member 42 can be movably connected to the protective frame 5, and can also prevent the roller 411 or the flexible contact member 42 from contacting the second device body 82, the second display screen 84 or the secondary screen protective film, further reducing the probability of damage to the second device body 82, the second display screen 84 or the secondary screen protective film.

[0076] Optionally, the protection frame 5 is a frame with a hole in the middle.

[0077] In the embodiment of the present application, the protective frame 5 is a frame with a hole in the middle, which is convenient for protecting the circumference of the second device body 82, and the second display screen 84 is exposed through the area of ​​the hole in the middle, so as to ensure the display effect of the electronic device 80 in the folded state.

[0078] In some optional embodiments, the protective member includes a roller 411 , and the protective frame 5 is provided with a guide slope 51 ; when the protective cover 10 is installed on the electronic device 80 , the roller 411 rolls along the guide slope 51 .

[0079] In the embodiment of the present application, the guide slope 51 can play a guiding role, so that the roller 411 can roll along the guide slope 51, which can avoid the roller 411 from getting stuck and improve the smoothness of the folding or unfolding of the rotating part 2 relative to the main body 1.

[0080] Specifically, two guide slopes 51 may be respectively provided at both ends of the protection frame 5, which cooperate with the rollers 411 at both ends of the rotating part 2. Specifically, the roller 411 can roll on the guide slopes 51, which can prevent the roller 411 from being stuck by the protection frame 5, and ensure the smoothness of the rolling of the roller 411. The guide slopes 51 are inclined toward the roller 411, and when the electronic device 80 switches from the unfolded state to the folded state, the roller 411 is in a climbing state.

[0081] For example, rollers 411 are provided at both ends of the rotating part 2, and the rollers 411 are mounted on the rotating part 2 through the rotating shaft 412. The two ends of the protective frame 5 are made into slopes to facilitate the rolling of the rollers 411 and avoid the rollers 411 from moving unsmoothly or unable to move. The rollers 411 are allowed to roll on the slope of the protective frame 5, and rolling friction is formed between the rollers 411 and the protective frame 5.
