Description

Technical Field

[0001] The invention relates to the technical field of electronic equipment accessories, and in particular to a universal assembled multifunctional mobile phone case. Background Art

[0002] With the development of technology and communication, mobile phones have become an indispensable communication tool in people's daily life and work. In related technologies, in order to protect mobile phones from external bumps and impacts, people use an external accessory (i.e., mobile phone case) to wrap the mobile phone to achieve the protective effect.

[0003] However, as the replacement of mobile phones becomes more and more frequent, people change their mobile phones more and more frequently. Mobile phones need to be equipped with exclusive mobile phone cases according to brands, models and sizes, which will cause the following problems: on the one hand, when producing mobile phone cases, in order to cope with the ever-changing shapes and sizes of mobile phones, manufacturers have to frequently change molds, which brings many inconveniences to production; on the other hand, when consumers change their mobile phones, they must re-configure new mobile phone cases, which is bound to cause a lot of waste of mobile phone cases. In addition, as one of the most commonly used accessories for protecting and decorating the appearance of mobile phones, mobile phone cases are very rich in variety. At present, the mainstream mobile phone cases on the market are made of plastic, silicone, metal tempered glass, leather and metal. Among them, plastic and silicone mobile phone cases are widely used due to their easy processing and low cost, but they have a bad grip, poor heat dissipation and durability; metal tempered glass mobile phone cases are comfortable to hold, wear-resistant and scratch-resistant, but have poor anti-slip ability and are easily damaged; leather mobile phone cases are comfortable to hold, but they are expensive, and have poor durability and heat dissipation; metal mobile phone cases are comfortable to hold, dirt-resistant and wear-resistant, and have good heat dissipation performance, but the fully-wrapped metal mobile phone cases in the past were of high quality and would affect the signal of the mobile phone. At the same time, most mobile phone cases on the market can only provide a single protection function, and some mobile phone cases only have the function of serving as mobile phone holders. There are few compatible products for the magnetic function of current mainstream mobile phones. This results in the need to take off the mobile phone case or purchase corresponding magnetic accessories when connecting magnetic chargers, holders, radiators and other magnetic accessories, which greatly reduces the user experience. Moreover, most of these mobile phone cases are full-edge mobile phone cases. When connecting magnetic accessories for wireless charging, the heat dissipation performance of the mobile phone decreases, thereby reducing the charging power of the mobile phone, which runs counter to the original design intention of the mobile phone wireless charging function.

[0004] As mentioned in the review, in order to solve the above-mentioned problems of mobile phone cases currently on the market, it is urgent to develop a mobile phone case that can not only reduce the damage caused by accidental drops of mobile phones and reduce the appearance wear and tear caused by daily use of mobile phones, but also meet the modern users' demands for versatility and high adaptability of mobile phone cases.

DETAILED DESCRIPTION

[0019] The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 21 As shown, the present invention discloses a universal assembled multifunctional mobile phone case, which is applied to a mobile phone. The mobile phone case comprises a support arm 1, a frame 2 and a bracket 3, wherein the support arm 1 is used to support the mobile phone and provide protection, and the shape of the support arm 1 can be adaptively set as required. In one example, as Figure 1 and Figure 2 As shown, the support arm 1 is a rectangular structure. During use, the side of the support arm 1 with a rectangular structure can fit closely with the back of the mobile phone, effectively ensuring the safety of the mobile phone. The frame 2 is arranged at the end of the support arm 1. The frame 2 has a telescopic portion 21 and a fixed portion 22. The fixed portion 22 is slidably connected to the telescopic portion 21 and the support arm 1, so that the frame 2 has adjustable telescopicity, that is, the telescopic portion 21 can be adjusted along the width direction of the mobile phone (such as Figure 1 The fixed part 22 can slide freely in the x direction as shown in the figure. Meanwhile, during use, the fixed part 22 drives the telescopic part 21 to slide along the Figure 1 The bracket 3 is moved in the y direction as shown in the figure, so that the user can adjust the mobile phone according to different models and sizes to ensure that the mobile phone can be firmly mounted in the mobile phone case. The bracket 3 is installed on the support arm 1, and the extension direction of the bracket 3 (as shown in the figure) is Figure 1 The x direction shown in FIG) and the extension direction of the telescopic portion 21 (as shown in FIG Figure 1 The user slides the frame 2 according to the model of the mobile phone and snaps it into the mobile phone, and then moves in the extension direction of the support arm 1 (as shown in the x direction). Figure 1In the y direction shown in the figure, the sliding support arm 1 drives the bracket 3 to engage with the lens module of the mobile phone, thereby adapting to different mobile phone lens modules, and can directly connect magnetic accessories to avoid other restrictions that reduce the heat dissipation performance of the mobile phone. At the same time, the bracket 3 enables the mobile phone case to provide additional support functions. The user can adjust the appropriate angle as needed to support the mobile phone and provide convenience for the user.

[0021] In the assembled state, the user only needs to place the mobile phone at the supporting position of the support arm 1, slide the telescopic part 21 and the fixed part 22 to engage with the mobile phone, that is, Figure 1 The telescopic portion 21 is slidable in the x direction as shown in FIG. 2 to adjust the length of the frame 2 to fit the width of the mobile phone. Figure 1 As shown in the figure, the fixing part 22 is moved in the y direction to adjust the position of the entire frame 2 to adapt to the length of the mobile phone, so that it can firmly clamp the mobile phone, and at the same time, the support arm 1 is slid to drive the bracket 3 to engage with the lens module of the mobile phone, so that the lens module is located between the frame 2 and the bracket 3 and is firmly fixed, thereby adapting to different mobile phone lens modules. In addition, during use, the bracket 3 can also provide additional support to help the mobile phone maintain a vertical or other required angle stable placement plane for users to watch or use, so that it can be easily adapted to different models of mobile phones to ensure the safety and adaptability of the mobile phone. At the same time, different from the previous metal full-edge mobile phone case, the mobile phone case is set to a middle hollow structure through the mutual cooperation and assembly of the frame 2, the support arm 1 and the bracket 3, so that the structure is not only simple and light, comfortable to hold, and does not block the signal of the mobile phone, but also the mobile phone can be directly connected to the magnetic suction accessories without reducing the heat dissipation performance of the mobile phone.

[0022] In some embodiments, Figure 1 and Figure 2 As shown, the telescopic part 21 is slidably connected with the fixed part 22, and one end of the telescopic part 21 has a first groove 23, and a first telescopic member 4 is arranged in the first groove 23. The function of the first telescopic member 4 is to provide a certain elastic force, so that the telescopic part 21 can maintain a certain tension or compression state during the sliding process, so as to effectively clamp the mobile phone. The first telescopic member 4 can be a circular spring or a spring sheet. The fixed part 22 is a hollow structure, and a hole 24 is arranged on the fixed part 22. The hole 24 cooperates with the first block structure 5, wherein the hole 24 can be located at the top of the telescopic part 21 or at the side of the telescopic part 21.

[0023] In one example, if Figure 1 and Fig. 9As shown, the hole 24 is a latch hole and is located on the side of the telescopic part 21, and the first telescopic member 4 is a spring sheet, and the first block structure 5 is a first latch block. When the telescopic part 21 is assembled with the fixed part 22, the first groove 23 of the telescopic part 21 is inserted into the fixed part 22, and the first latch block is placed in the fixed part 22 through the latch hole. There is a notch on the hole 24, which can clamp the spring sheet, thereby realizing the connection between the telescopic part 21 and the fixed part 22. When in use, the telescopic part 21 is slid to compress the spring sheet to increase the length of the frame 2 and adapt to the required mobile phone size. When disassembly is required, it is only necessary to gently push the first latch block with a sharp object to remove it from the fixed part 22, and slide the telescopic part 21 again to release the force of the spring sheet, and remove the mobile phone case from the mobile phone, thereby completing the disassembly. It should be noted that the first telescopic member adopts a spring sheet, which can effectively reduce the overall thickness of the mobile phone case in the assembled state, thereby facilitating the user to carry and improving the user's feel.

[0024] In another example, if Figure 2 and Fig.18 As shown, the hole 24 is a blind hole and is located at the top of the telescopic part 21, and the first telescopic member 4 is a circular spring, and the first block structure 5 is a first convex block, and the first convex block matches the blind hole. In the assembled state, the first groove 23 is inserted into the fixing part 22, and the first convex block is inserted into the blind hole to complete the combination of the telescopic part 21 and the fixing part 22. When the mobile phone case is used, the mobile phone case is arranged along the width direction of the mobile phone (such as Figure 1 The telescopic part 21 is slidably moved in the x direction as shown in the figure to compress the circular spring so as to increase the length of the frame 2 and to fit the required size of the mobile phone for snapping, thereby ensuring that the telescopic part 21 does not slide due to external force when the mobile phone case is adjusted, and can effectively limit the relative movement of the telescopic part 21, so that the frame 2 is firmly snapped and fixed on the mobile phone, ensuring the stability of the mobile phone in the mobile phone case. When disassembly is required, the telescopic part 21 is slid again to release the force of the circular spring and remove the mobile phone case from the mobile phone, thereby adapting to different models of mobile phones, thereby realizing the flexibility and convenience of the mobile phone case.

[0025] In some embodiments, the number of the borders 2 can be adaptively set as needed, and can be two or four. Figures 3 to 7As shown, two frames 2 are provided, and the frame 2 includes a first frame 25 and a second frame 26, which are respectively arranged on both sides of the support arm 1, wherein the first frame 25 has a first telescopic portion 251 and a first fixed portion 252, and the first telescopic portion 251 is connected to the first fixed portion 252 by snap-fitting, and the first telescopic portion 251 has a first groove 23 on one side close to the first fixed portion 252, and the first fixed portion 252 has a hole 24. In the assembled state, the first groove 23 is inserted into the first fixed portion 252, and the first block structure 5 is inserted into the hole 24 on the first fixed portion 252 to complete the combination of the first telescopic portion 251 and the first fixed portion 252. At the same time, it should be noted that along the extension direction of the support arm 1 (such as Figure 3 The length of the first block structure 5 is greater than the length of the first telescopic portion 251. This is because if the first block structure 5 is consistent with the width of the first telescopic portion 251, the first block structure 5 will be a single-sided cantilever structure, which is prone to shear failure. Therefore, the length of the first block structure 5 is greater than the length of the first telescopic portion 251, so that the reaction force of the first telescopic member 4 is better transmitted to the first fixing portion 252, thereby making the structure more durable. At the same time, the first telescopic portion 251 can be limited along the width direction of the mobile phone (such as Figure 2 In order to avoid being pulled out, the first telescopic part 251 is slid to compress the first telescopic member 4 to increase the length of the first frame 25 and to adapt to the size of the required mobile phone for snapping, so that the first frame 25 is firmly snapped and fixed on the mobile phone, thereby meeting the needs of different models of mobile phones. The second frame 26 has a second telescopic part 261 and a second fixed part 262. The connection and use of the second telescopic part 261 and the second fixed part 262 are consistent with the connection and use of the first telescopic part 251 and the first fixed part 252. This will not be described in detail in the present application.

[0026] In another example, if Figures 3 to 21 As shown, the shape of the frame 2 can be set according to the required adaptability. For example, the first frame 25 and the second frame 26 are both L-shaped structures. The L-shaped first frame 25 and the second frame 26 provide better protection at the four corners of the mobile phone, forming a solid protective layer that can effectively absorb external impacts, reduce the risk of damage to the corners, and increase the hollow space in the middle to accommodate larger magnetic accessories. For another example, the first frame 25 and the second frame 26 are both T-shaped structures. The T-shaped first frame 25 and the second frame 26 provide stronger support for the mobile phone case, so that the mobile phone case can not only firmly wrap the mobile phone, but the T-shaped frame can also serve as a support point to improve the stability of the mobile phone case.

[0027] Among them, Figure 7 and Fig.16As shown, the two ends of the support arm 1 have a first protrusion 11 and a second protrusion 12 respectively. The first protrusion 11 is slidably connected to the first fixing portion 252, and the second protrusion 12 is snap-fitted to the second fixing portion 262. In the assembled state, the user moves the first fixing portion 252 along the extension direction of the support arm 1 to adapt to the length of the mobile phone, thereby snapping into the mobile phone and protecting the mobile phone from external collisions.

[0028] In some embodiments, continue to refer to Figure 7 and Fig.16 The first protrusion 11 has a second groove 110 for accommodating the second telescopic member 6, along the extension direction of the support arm 1 (such as Figure 7 The length of the second groove 110 is less than the length of the first protrusion 11 and is aligned with the setting direction of the second telescopic member 6 (as shown in the y direction). Figure 7 In the assembled state, the first protrusion 11 is inserted into the first fixing portion 252, and the moving position of the first fixing portion 252 is limited by the second block structure 7, wherein the second telescopic member 6 can be a circular spring or a spring sheet. In one example, as shown in Figure 7 As shown, the second telescopic member 6 is a spring sheet, the second block structure 7 is a second latch block, the hole 24 is a latch hole and is located on the side of the first fixed part 252. In the assembled state, the first protrusion 11 and the spring sheet are inserted into the first fixed part 252, and the second latch block is located in the first fixed part 252 through the latch hole. The second latch block has a notch to clamp the spring sheet, effectively preventing the latch from slipping off during use, thereby limiting the movement of the first fixed part 252. After use, the second latch block can be removed from the first fixed part 252 by gently pushing with a sharp object, thereby facilitating assembly and disassembly. In another example, as Fig.16 As shown, the second telescopic member 6 is a circular spring, the second block structure 7 is a second protrusion, and the hole 24 is a blind hole located at the top of the first fixed part 252. In the assembled state, the first protrusion 11 is inserted into the first fixed part 252 and is clamped in the blind hole on the first fixed part 252 through the second protrusion, thereby limiting the moving position of the first fixed part 252. The user can move the first fixed part 252 according to the length of the mobile phone and apply tension to the circular spring, so that the length of the support arm 1 matches the length of the mobile phone and is clamped.

[0029] In some embodiments, Figures 7 to 21 As shown, the second protrusion 12 is detachably connected to the second fixing portion 262, for example, Figures 7 to 12As shown, the second protrusion 12 has a limiting groove 120. In the assembled state, the third block structure 8 is placed in the limiting groove 120 and is clamped on the second fixing portion 262. Along the extension direction of the support arm 1, a plurality of holes 24 are provided on the side of the second fixing portion 262. The third block structure 8 is inserted into the corresponding holes 24 as required to achieve the fixation of the support arm 1 and the second fixing portion 262, wherein the third block structure 8 is a third latch block, and the hole 24 can be a latch hole. The second protrusion 12 is inserted into the second fixing portion 262, and the third latch block is inserted into the second fixing portion 262 through the latch hole, so that the third latch block is plugged into the second protrusion 12, thereby completing the connection between the support arm 1 and the second fixing portion 262.

[0030] For example, Figures 15 to 21 As shown, the second protrusion 12 is provided with a square hole 121 for accommodating the third telescopic member 9. The third telescopic member 9 is a circular spring. The setting direction of the circular spring (as shown in FIG. Fig.16 The z direction shown in FIG. 1 ) and the extension direction of the support arm 1 (as shown in FIG. Fig.16 The second fixing portion 262 is perpendicular to the y direction shown in the figure, and a plurality of holes 24 are arranged on the top of the second fixing portion 262 along the extension direction of the support arm 1, wherein the third block structure 8 is a third protrusion, and the hole 24 is a through hole, the third protrusion matches the through hole, and the third protrusion is placed in the through hole as required to adjust the length of the support arm 1. In the assembled state, the second protrusion 12 is inserted into the second fixing portion 262, the square hole 121 is aligned with the required through hole, and the third protrusion is clamped in the square hole 121 of the support arm 1 through the through hole on the second fixing portion 262, thereby completing the connection between the support arm 1 and the second fixing portion 262.

[0031] like Figure 7 and Fig.16 As shown, since most mobile phone lens modules are generally close to the top of the mobile phone, a lens groove 2511 is provided on the first telescopic portion 251 .

[0032] In some embodiments, the bracket 3 is a rectangular structure, and the bracket 3 provides support for the mobile phone. The bracket 3 is composed of multiple sections, which can be two sections or four sections. Figure 3 , Figure 6 and Figure 7 as well as Fig.13As shown, the bracket 3 has two sections, namely the first bracket 31 and the second bracket 32. The first bracket 31 is rotatably connected to the support arm 1 and the second bracket 32 ​​through the connecting member 10. It should be noted that the connecting member 10 can be a pin or bolt with a certain preload force, or a damping hinge or a rotating shaft, etc., as long as the two brackets can be connected, no further elaboration will be given in this application. During use, the first bracket 31 and the second bracket 32 ​​are moved along the extension direction of the support arm 1, so that the first bracket 31 and the second bracket 32 ​​are snapped with the mobile phone lens module, so that the user can directly use the magnetic suction accessories to charge the mobile phone. At the same time, the user can rotate the two sections or one section to achieve the desired angle as needed, so as to serve as the vertical and horizontal support of the mobile phone, which is convenient for watching videos, making video calls or performing other operations.

[0033] In some embodiments, continue to refer to Figure 3 , Figure 6 and Figure 7 as well as Fig.13 , the second bracket 32 ​​can rotate relative to the first bracket 31 along the circumferential direction of the connecting member 10, wherein one side of the first bracket 31 has a third groove 310. In the assembled state, the second bracket 32 ​​is placed in the third groove 310. If the mobile phone needs to connect a magnetic accessory, the bracket 3 can be directly connected by rotating it toward the side away from the mobile phone, which will not affect the heat dissipation of the mobile phone. When the mobile phone is not in use, the second bracket 32 ​​is rotated until it is in the third groove 310, and the first bracket 31 is rotated at the same time so that the first bracket 31 is close to the side wall of the mobile phone. It should be noted that along the thickness direction of the support arm 1 (such as Figure 3 In the z direction shown in FIG, the thickness of the bracket 3 is consistent with the thickness of the frame 2 and the support arm 1, which can reduce the wear and tear and bumps caused by the daily use of the mobile phone lens module.

[0034] In some embodiments, the side wall of the frame 2 is provided with a wrap angle 100 for engaging the edge of the mobile phone. Figures 3 to 21 As shown, the corners of the first telescopic portion 251, the second telescopic portion 261, the first fixing portion 252 and the second fixing portion 262 are all provided with a wrap angle 100, and the wrap angle 100 is arranged along the thickness direction of the support arm 1 (such as Figure 3 In the process of using the mobile phone, the mobile phone can be better protected from external bumps. In another example, continue to refer to Figures 3 to 21 The arc-shaped air cushion 200 is provided outside the wrap angle 100. The arc-shaped air cushion 200 can be connected to the wrap angle 100 by bonding, or can be an integral structure with the wrap angle 100. Figure 3In the z direction as shown in the figure, the height of the arc-shaped air cushion 200 and the height of the wrap angle 100 can be adaptively set as needed. In this regard, the present application does not impose too many restrictions. During use, the arc-shaped air cushion 200 can buffer and absorb energy when the mobile phone accidentally falls, effectively reducing the external impact force, thereby protecting the mobile phone.

[0035] The steps of assembling and using a universal assembled multifunctional mobile phone case in this application are as follows: like Figures 1 to 21 As shown, the mobile phone case is first assembled, and the first telescopic part 251 is connected to the first fixed part 252 by means of a latch. The first telescopic part 251 has a first groove 23 on one side close to the first fixed part 252, and the first fixed part 252 has a hole 24. In the assembled state, the first groove 23 is inserted into the first fixed part 252, and the first block structure 5 is inserted into the hole 24 on the first fixed part 252 to complete the combination of the first telescopic part 251 and the first fixed part 252. The connection method of the second telescopic part 261 and the second fixed part 262 is consistent with the connection method of the first telescopic part 251 and the first fixed part 252 mentioned above.

[0036] Afterwards, the first fixing part 252 is plugged into the support arm 1, that is, the first protrusion 11 on the support arm 1 is inserted into the first fixing part 252 and plugged with the second block structure 7, and the second protrusion 12 on the support arm 1 is inserted into the second fixing part 262 and clamped with the third block structure 8.

[0037] Next, the bracket 3 is rotatably mounted on the support arm 1 through the connecting piece 10, thereby completing the assembly of the mobile phone case.

[0038] When the mobile phone case is used, the support arm 1 is attached to the back of the mobile phone, and the first telescopic portion 251 and the second telescopic portion 261 are extended along the extension direction of the first frame 25 (such as Figure 3The first telescopic portion 251 and the second telescopic portion 261 are slid and stretched to the required width of the mobile phone, the wrapping angle 100 on the first telescopic portion 251 and the second telescopic portion 261 are snapped with the edge of the mobile phone, the first fixing portion 252 is slid and stretched along the extension direction of the support arm 1 to the required length of the mobile phone to snap with the edge of the mobile phone, and the bracket 3 slides along the extension direction of the support arm 1, so that the bracket 3 is snapped with the mobile phone lens module, that is, the position of the bracket 3 exceeds the lower edge of the mobile phone lens module. When the user needs to use the mobile phone in landscape mode, the second bracket 32 ​​of the bracket 3 can be rotated to a suitable angle to serve as a landscape bracket for the mobile phone. When the user needs to use the mobile phone in portrait mode, the second bracket 32 ​​can be rotated to a suitable angle, and the first bracket 31 of the bracket 3 can be rotated to be level with the mobile phone case. At this time, the first bracket 31 and the second bracket 32 ​​jointly serve as a portrait bracket for the mobile phone. At the same time, when the mobile phone needs to be connected to a magnetic accessory, the second bracket 32 ​​is rotated to the maximum angle to increase the hollow area on the back of the mobile phone, that is, the size requirements of most magnetic devices can be met without removing the mobile phone case. When the mobile phone is not in use, the bracket 3 can be placed horizontally, that is, the extension direction of the bracket 3 (such as Figure 3 ) and the extension direction of the frame 2 (as shown in the x direction Figure 3 The x direction shown in the figure is parallel to the x direction), thereby achieving the protection safety and convenience of the mobile phone.
