Description

Technical Field

[0001] The utility model relates to the field of mobile phone casings, and particularly to a mobile phone casing and a mobile phone. Background Art

[0002] Currently, the mobile phone casing mainly consists of a front shell and a rear shell. To join the front shell and the rear shell, the following common implementation methods are adopted: First, the snap - type method. Specifically, a first snap - fitting part is provided on the front shell, and a second snap - fitting part is provided on the rear shell, so that the front shell and the rear shell are joined by the snap - fitting of the first snap - fitting part and the second snap - fitting part; Second, the fixing method using screws and foam adhesives. Specifically, after the front shell and the middle frame are locked by screws, the rear shell is pasted to the middle frame with foam adhesive, thus assembling the mobile phone.

[0003] When the mobile phone needs to be disassembled for repair, the first step is usually to first disassemble the rear shell to separate the rear shell from the front shell. For the front shell and the rear shell joined by the snap - type method, the repair personnel usually first look for the insertable gap between the front shell and the rear shell of the mobile phone, use a disassembly pick or a pry bar to insert into this gap, and then move along the mobile phone frame to gently pry open the snaps on the mobile phone casing one by one. When prying, too much force cannot be used to avoid damaging the casing or internal components; for the fixing method using screws and foam adhesives, the repair personnel need to use tools such as a mobile phone separator or a heat gun to heat the edge of the rear shell to soften the foam adhesive, and then use a suction cup or a pry bar to disassemble the rear shell. When heating, attention should be paid to controlling the temperature and heating time to avoid overheating and damaging the internal components of the mobile phone. When disassembling the rear shell, attention should also be paid not to use too much force to avoid damaging the mobile phone.

[0004] It can be seen that it is very inconvenient to disassemble the front shell and the rear shell of the mobile phone during mobile phone disassembly and repair, and the operation requirements during the casing disassembly process are also relatively high, resulting in low efficiency of mobile phone disassembly and repair. Summary of the Invention

[0005] Based on this, the purpose of the utility model is to overcome the defects or deficiencies of the prior art, and provide a mobile phone casing, the structure of which can quickly disassemble the mobile phone casing and improve the efficiency of mobile phone disassembly and repair.

[0006] The utility model is realized through the following technical solutions: A mobile phone casing includes a first housing and a second housing. The first housing is provided with a first snap - fitting part, and the second housing is provided with a second snap - fitting part. The first housing and the second housing are assembled by snap - fitting through the first snap - fitting part and the second snap - fitting part, and at least part of the second housing surrounds the first housing. A pry hole is also provided on the side surface of the second housing. The part of the first housing located inside the second housing is provided with a top - pressing force - receiving structure corresponding to the position of the pry hole. The end of the pry bar passing through the pry hole can be abutted against the top - pressing force - receiving structure.

[0007] Compared with the prior art, for the mobile phone shell provided by the present utility model, the first shell and the second shell are connected by buckles. By providing a pry hole and a pressing force receiving structure, when disassembling and repairing the mobile phone, the repair personnel only need to insert a pry bar into the pry hole and make the end of the pry bar abut against the pressing force receiving structure, and based on the lever principle, pry open the buckle, so as to realize the rapid separation of the first shell and the second shell, thereby improving the efficiency of disassembling and repairing the mobile phone.

[0008] Further, the cross-section of the pry hole is quadrilateral. The pry hole with a quadrilateral cross-section is convenient for inserting or removing the pry bar.

[0009] Further, the quadrilateral is a rectangle. The rectangular pry hole itself has good structural stability and can provide a good supporting effect when prying open the buckle. In addition, the rectangular pry hole has a more uniform stress distribution when stressed, which can reduce local stress concentration and avoid excessive deformation or direct damage of the second shell.

[0010] Further, the pressing force receiving structure is a slope surface provided on the side surface of the first shell, and the slope surface is arranged to gradually move away from the back surface of the second shell along the direction close to the side surface of the second shell. Designing the pressing force receiving structure as a slope surface can increase the contact area between the pry bar and the slope surface, increase the friction force between the pry bar and the first shell, prevent the pry bar from sliding during the prying process, and can also effectively disperse the pressure when the first shell is pressed. At the same time, setting the inclination direction of the slope surface to gradually move away from the back surface of the second shell along the direction close to the side surface of the second shell ensures that the direction of the force applied by the pry bar on the slope surface is roughly the same as the direction of movement of the first buckle part away from the second buckle part, making it easier to pry open the buckle.

[0011] Further, a card slot for inserting a SIM card tray is provided on the side surface of the second shell, and the pry hole is arranged in the card slot. Through the above setting, when disassembling the mobile phone, after the repair personnel take out the SIM card, they can directly use the pry bar to insert into the pry hole to pry open the mobile phone shell, which is convenient for disassembly and repair. At the same time, the pry hole is arranged in the card slot, and the card tray for installing the SIM card can cover the pry hole, which can prevent dust and moisture from entering the mobile phone through the pry hole to a certain extent and can also ensure the beauty and cleanliness of the mobile phone.

[0012] Further, the first buckle part includes a support part extending backward from the back surface of the first shell and a first protrusion part extending outward from the support part, and a second protrusion part extending inward is provided on the inner side surface of the second shell. The second buckle part is a recess formed between the second protrusion part and the inner side of the back surface of the second shell, and the recess forms a buckle fit with the first protrusion part. The first shell and the second shell are connected by buckles, which is convenient for the rapid disassembly and rapid assembly of the first shell and the second shell.

[0013] Further, the surface of the first convex portion for contacting the second convex portion is an inclined surface, which is arranged to gradually approach the back surface of the second housing along the extending direction of the first convex portion, and the surface of the second convex portion for contacting the first convex portion is parallel to this inclined surface. When using a crowbar to pry open the buckle, the first buckle portion can easily and quickly slide out of the second buckle portion along the inclined surface, thereby realizing the rapid separation of the first housing and the second housing.

[0014] Further, both the first buckle portion and the second buckle portion are plastic parts, and the pressing force-bearing structure is a metal part. Since the plastic material has good elasticity and toughness, the buckle can deform to a certain extent when subjected to the prying force, reducing the difficulty of prying, and the maintenance personnel can smoothly pry open the buckle with a relatively small force, which is very convenient. Since the pressing force-bearing structure bears most of the prying force, the pressing force-bearing structure is made of metal material and can bear a large force and stress, avoiding deformation or damage of the first housing.

[0015] Further, a groove is provided at the side edge of the second housing, and a third convex portion corresponding to the groove is provided in the area where the side surface of the first housing is attached to the second housing. The third convex portion and the groove are engaged with each other. Through the above settings, it is convenient to position the first housing and the second housing during the buckle assembly, and at the same time, the side edge of the second housing is closely attached to the first housing, improving the sealing performance, and making the appearance of the mobile phone neat and beautiful.

[0016] The present utility model also provides a mobile phone, which has the mobile phone housing as described above.

[0017] For better understanding and implementation, the present utility model will be described in detail below with reference to the accompanying drawings. Description of the Drawings

[0021] In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figure 1 , this embodiment provides a mobile phone shell. Specifically, the mobile phone shell includes a first shell and a second shell. The second shell at least partially surrounds the first shell. The first shell is provided with a first buckle portion 11, and the second shell is provided with a second buckle portion 21 corresponding to the first buckle portion. The first shell and the second shell are assembled by buckling through the first buckle portion 11 and the second buckle portion 21. A pry hole 23 is further provided on the side surface of the second shell. A top pressure stress structure corresponding to the position of the pry hole 23 is provided on the part of the first shell located inside the second shell. The end of the pry bar passing through the pry hole 23 can abut against the top pressure stress structure. In this embodiment, the first shell is the front shell 10, and the second shell is the rear shell 20. Through the above settings, the pry bar can abut against the top pressure stress structure provided on the front shell 10 through the pry hole 23 on the side surface of the rear shell 20, and pry open the mutually engaged first buckle portion 11 and the second buckle portion 21 based on the lever principle, so as to realize the rapid disassembly of the front shell 10 and the rear shell 20.

[0024] The following further details the structure of the mobile phone shell of the present utility model.

[0025] As Figure 1 shown, the rear shell 20 at least partially surrounds the front shell 10. Specifically, the rear shell 20 includes a rear shell body and side portions provided at the four peripheral edges of the rear shell body. The side portions and the rear shell body are integrally designed, and a semi-closed space is formed between the side portions and the rear shell body. The front shell 10 includes a front shell body and side portions provided at the four peripheral edges of the front shell body. A semi-closed space is formed between the side portions and the front shell body. The semi-closed space formed between the rear shell body and the side portions provided at the four peripheral edges of the rear shell body at least partially surrounds the semi-closed space formed between the front shell body and the side portions provided at the four peripheral edges of the front shell body.

[0026] The side portion of the front shell is provided with a first buckle portion 11. The first buckle portion 11 is generally in an inverted "L" shape, and it includes a support portion 111 and a first protrusion portion 112. Specifically, the support portion 111 extends backward from the back surface of the front shell 10, and the first protrusion portion 112 extends outward from the support portion 111. In this embodiment, the support portion 111 and the first protrusion portion 112 are integrally formed, and the support portion 111 is fixedly installed on the back surface of the front shell 10. Of course, in other alternative embodiments, the support portion 111, the first protrusion portion 112 and the front shell 10 are integrally formed.

[0027] The rear shell 20 is provided with a second snap portion 21 corresponding to the first snap portion 11, and the second snap portion 21 is a recess provided on the inner side surface of the rear shell 20. Specifically, a second protrusion 22 extending inward is provided on the inner side surface of the rear shell 20, and a recess is formed between the second protrusion 22 and the inner side of the back surface of the rear shell 20. In this embodiment, the second protrusion 22 is integrally formed with the rear shell 20. Of course, in other alternative embodiments, the second protrusion 22 may be a part fixedly installed on the inner side surface of the rear shell 20.

[0028] Through the above settings, the first snap portion 11 and the second snap portion 21 form a snap fit through the cooperation of the first protrusion 112 and the recess, so that the front shell 10 and the rear shell 20 are convenient for disassembly and assembly.

[0029] Please refer to Figure 1 and Figure 2 , a pry hole 23 for allowing a pry bar to pass through is further provided on the side surface of the rear shell 20. Specifically, a card slot 24 for inserting a SIM card tray is provided on the side surface of the rear shell 20, and the pry hole 23 is provided in the card slot 24. In this embodiment, the cross-section of the pry hole 23 is quadrilateral, preferably rectangular. The pry hole 23 with a rectangular cross-section is convenient for inserting or removing the pry bar. Moreover, when prying open the snap, the pry hole 23 with a rectangular cross-section itself has good structural stability, can provide a good supporting effect. At the same time, the pry hole 23 with a rectangular cross-section has a more uniform stress distribution when stressed, can reduce local stress concentration, and can avoid excessive deformation or direct damage of the rear shell. In addition, since the pry hole 23 is mainly used for the entry and exit of the pry bar, in other alternative embodiments, the cross-section of the pry hole 23 can be circular, elliptical, triangular, pentagonal and other shapes, not limited to quadrilateral.

[0030] A top pressure stress structure corresponding to the position of the pry hole 23 is provided at the part of the front shell 10 surrounded by the rear shell 20, and the end of the pry bar passing through the pry hole 23 can abut against the top pressure stress structure. Specifically, the top pressure stress structure is a ramp surface 12 provided on the side surface of the front shell, and the ramp surface 12 is arranged to gradually move away from the back surface of the rear shell 20 along the direction close to the side surface of the rear shell 20. Designing the top pressure stress structure as the ramp surface 12 can increase the contact area between the pry bar and the ramp surface 12, can increase the friction between the pry bar and the ramp surface 12, prevent the pry bar from sliding during the prying process, and can also effectively disperse the pressure when the front shell 10 is subjected to top pressure. At the same time, setting the inclination direction of the ramp surface 12 to gradually move away from the back surface of the rear shell 20 along the direction close to the side surface of the rear shell 20 ensures that the direction of the force applied by the pry bar on the ramp surface 12 is substantially the same as the direction in which the first snap portion 11 moves away from the second snap portion 21, making it easier to pry open the snap. Of course, in other alternative embodiments, the top pressure stress structure can also be a curved surface or a horizontal surface.

[0031] With the above settings, the crowbar can abut against the slope surface 12 of the front shell 10 through the pry hole 23 on the side of the rear shell 20, and based on the lever principle, pry open the mutually engaged first snap portion 11 and second snap portion 21, thereby realizing the quick disassembly of the front shell 10 and the rear shell 20.

[0032] In addition, a groove 25 is provided at the side edge of the rear shell 20, and a third protrusion 13 corresponding to the groove 25 is provided in the area where the side surface of the front shell 10 fits with the rear shell 20. The third protrusion 13 and the groove 25 are mutually engaged. With the above settings, it is convenient to position the front shell 10 and the rear shell 20 during snap assembly. At the same time, the side edge of the rear shell 20 is closely attached to the front shell 10, improving the sealing performance, and making the appearance of the mobile phone neat and beautiful.

[0033] In order to further realize the quick disassembly of the front shell 10 and the rear shell 20 of the mobile phone. In this embodiment, the surface of the first protrusion 112 for contacting the second protrusion 22 is an inclined surface, and this inclined surface is set to gradually approach the back surface of the rear shell 20 along the extending direction of the first protrusion 112. Correspondingly, the surface of the second protrusion 22 for contacting the first protrusion 112 is parallel to this inclined surface. When using the crowbar to pry open the snap, the first snap portion 11 can easily and quickly slide out of the second snap portion 21 along the inclined surface, thereby realizing the quick separation of the front shell 10 and the rear shell 20. Of course, in other alternative embodiments, the surface of the first protrusion 112 for contacting the second protrusion 22 can be a curved surface, and this curved surface is also set to gradually approach the back surface of the rear shell 20 along the extending direction of the first protrusion 112. The surface of the second protrusion 22 for contacting the first protrusion 112 is a curved surface, and the two curved surfaces are equidistant.

[0034] In this embodiment, both the first snap portion 11 and the second snap portion 22 are plastic parts. The rear shell 20, the second protrusion 22 extending inward on the inner side surface of the rear shell 20, and the first snap portion 11 provided on the front shell 10 are all plastic parts. Since the plastic material has good elasticity and toughness, the snap can deform to a certain extent when subjected to the prying force, reducing the difficulty of prying open, and the maintenance personnel can smoothly pry open the snap with a relatively small force, which is very convenient. The top pressure stress structure is a metal part. Since the top pressure stress structure bears most of the prying force, the top pressure stress structure is a metal part, which can bear a large force and stress, and avoid deformation or damage of the front shell 10.

[0035] Embodiment Two

[0036] This embodiment provides a mobile phone case. The difference between the second embodiment and the first embodiment is that: the first housing is the rear case, and the second housing is the front case. That is, the front case at least partially surrounds the rear case. The rear case is provided with a first snap portion, and the front case is provided with a second snap portion corresponding to the first snap portion. The front case and the rear case are assembled by snapping through the first snap portion and the second snap portion. A pry hole is provided on the side of the front case, and a pressing force receiving structure corresponding to the position of the pry hole is provided on the portion of the rear case located inside the front case. The end of the pry bar passing through the pry hole can be abutted against the pressing force receiving structure. In this embodiment, for the specific structures of each part, please refer to the first embodiment and will not be elaborated here.

[0037] Embodiment Three

[0038] This embodiment provides a mobile phone, which has the mobile phone case as described in the first embodiment or the second embodiment. The mobile phone includes a display screen, a power supply, a control circuit module, a main board, a receiver, a microphone, a camera, a speaker, etc. The display screen is fixedly installed on the front of the front case. The main board and the power supply are arranged on the back of the front case. The control circuit module is integrated on the main board. The receiver, the microphone, the camera, and the speaker are all arranged on the main board and are electrically connected to the control circuit module. The rear case and the front case are connected by snaps, thereby wrapping the above components inside.

[0039] When disassembling and repairing the mobile phone, after the maintenance personnel take out the SIM card, they can directly use a pry bar to pass through the pry hole and abut against the inclined plane provided on the front case, and then apply a force to the hand-held end of the pry bar in a direction perpendicular to and away from the inclined plane, so as to pry out the first protrusion from the recess between the inclined plane and the back of the rear case, realizing the quick separation of the front case and the rear case; when assembling after repair, the maintenance personnel can position the front case and the rear case through the cooperation of the third protrusion and the groove. At the same time, the first protrusion and the recess are snapped together, thus realizing the quick assembly of the front case and the rear case, greatly improving the efficiency of mobile phone repair.

[0040] Compared with the prior art, for the mobile phone case provided by the utility model, the front case and the rear case are connected by snaps. By providing a pry hole and a pressing force receiving structure, when disassembling and repairing the mobile phone, the maintenance personnel only need to insert a pry bar into the pry hole and make the end of the pry bar abut against the pressing force receiving structure, and use the lever principle to pry open the snap, then the quick separation of the front case and the rear case can be realized, thereby improving the efficiency of disassembling and repairing the mobile phone.
