  Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

  An electronic apparatus 10 according to an embodiment of the present disclosure will be described with reference to FIGS. 1 and 2.

  The electronic device 10 is, for example, a foldable mobile phone, but may be any other device. As an outline, the electronic device 10 includes, for example, an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are connected to each other via a hinge portion 13 so as to be opened and closed. The hinge unit 13 includes, for example, a first hinge holding unit provided at an end of the upper casing 11 on the lower casing 12 side and a second hinge provided at an end of the lower casing 12 on the upper casing 11 side. The holding part and the tilt hinge held by the first hinge holding part and the second hinge holding part may be included. The upper housing 11 may be provided with a display and a receiver, for example. The lower housing 12 may be provided with, for example, a physical key and a microphone. As shown in FIG. 1, the state in which the upper housing 11 and the lower housing 12 are folded is also referred to as a closed state. In the closed state, the angle formed by the upper housing 11 and the lower housing 12 is, for example, approximately 0 °. As shown in FIG. 2, the state in which the upper housing 11 and the lower housing 12 are opened is also referred to as an open state. In the open state, the angle formed by the upper housing 11 and the lower housing 12 is, for example, less than 180 °. The inside of the upper housing 11 and the lower housing 12 in the closed state is also referred to as a front side. The outside of the upper housing 11 and the lower housing 12 in the closed state is also referred to as the rear side. The schematic shape of each of the upper housing 11 and the lower housing 12 may be a hexahedron having a front side surface, a rear side surface, and four side surfaces.

  The electronic device 10 includes various bumpers. As the material of the bumper, for example, an elastomer or the like can be used. By mounting the bumper, for example, durability of the electronic device 10 is improved.

  Specifically, the electronic device 10 includes a bumper at a place where there is a high probability that it will first collide with the ground when it is dropped in the open state. For example, the places where the probability of collision is high are two corners at the end of the upper casing 11 opposite to the lower casing 12 and the end of the lower casing 12 opposite to the upper casing 11 side. And two corners at the end of the lower housing 12 on the upper housing 11 side. For example, as illustrated in FIG. 3, the electronic device 10 includes one first bumper 16 that covers two corners at the end of the upper housing 11 opposite to the lower housing 12 side. . The electronic device 10 includes two second bumpers 27 that cover the two corners of the lower housing 12 at the end opposite to the upper housing 11 side. The electronic device 10 includes two third bumpers 28 that cover two corners of the lower housing 12 at the end of the lower housing 12 on the upper housing 11 side.

  For example, as illustrated in FIG. 1, when the electronic device 10 is in the closed state, each of the one or more third bumpers 28 may protrude outward from the upper housing 11 in the rotation axis X direction of the tilt hinge. With such a configuration, for example, when the electronic device 10 in a closed state falls, damage to the end portion of the upper housing 11 on the lower housing 12 side is reduced. For this reason, for example, damage to the end portion can be reduced without providing a bumper at the end portion of the upper case 11 on the lower case 12 side.

  The electronic device 10 includes a window portion 29, one or more bezel portions 30, and one or more fourth bumpers 31 on the rear surface of the upper housing 11. In the example shown in FIG. 1, there are two bezel portions 30 and two fourth bumpers 31.

  The window part 29 may be comprised with the transmissive member which permeate | transmits the light of a predetermined wavelength band, for example. For example, the user may be able to visually recognize the screen of the sub display provided in the upper housing 11 through the window portion 29.

  Each of the one or more bezel portions 30 may be provided as a separate body from the upper housing 11 or may be provided integrally on the rear side surface of the upper housing 11. Each of the one or more bezel portions 30 surrounds a part of the periphery of the window portion 29. As shown in FIG. 4, each of the one or more bezel portions 30 may protrude outward from the window portion 29 from the rear side surface of the upper housing 11.

  Each of the one or more fourth bumpers 31 surrounds a part of the periphery of the window portion 29. Each of the one or more fourth bumpers 31 may be arranged at equal intervals in the circumferential direction of the window portion 29. Each of the one or more fourth bumpers 31 may be fixed to the upper housing 11 using, for example, an adhesive member and a fastening member. The adhesive member may include, for example, an adhesive and a double-sided tape. The fastening member may include a screw or the like, for example. As shown in FIG. 4, each of the one or more fourth bumpers 31 may protrude outward from the window portion 29 and each bezel portion 30 from the rear surface of the upper housing 11.

  For example, when the electronic device 10 falls, the fourth bumper 31 reduces damage to the window portion 29 and each bezel portion 30. Even when the fourth bumper 31 provided as a separate body from the upper housing 11 is damaged, the operator only needs to replace the fourth bumper 31 in the repair work. Since it is not necessary to disassemble the upper housing 11, the work load of the repair work is reduced.

  The upper housing 11 will be described in detail with reference to FIG. FIG. 5 shows a front end portion of the upper housing 11 opposite to the hinge portion 13. In FIG. 5, electronic components such as a substrate and a display device provided in the upper housing 11 are not shown. As shown in FIG. 5, the upper housing 11 includes a front case 14 and a rear case 15. The front case 14 is located on the front side of the upper housing 11. The rear case 15 is located on the rear side of the upper housing 11. A first bumper 16 is attached to the upper housing 11. As a material of the front case 14 and the rear case 15, for example, a resin containing glass can be used.

  In the assembly process of the upper housing 11, for example, the first bumper 16 is temporarily fixed to the front case 14. Details of the temporary fixing of the first bumper 16 will be described later. After the first bumper 16 is temporarily fixed, the rear case 15 is locked to the front case 14. For example, the front case 14 and the rear case 15 may be locked by locking portions provided in the front case 14 and the rear case 15, respectively. The locking portion may include, for example, a hook shape or a claw shape. After the rear case 15 is locked, the front case 14 and the rear case 15 are fixed by a fastening member such as a screw. In this way, the upper housing 11 is assembled. In a state where the upper housing 11 is assembled, the first bumper 16 covers a part of the side surface of the upper housing 11. For example, the first bumper 16 covers the side surface of the upper housing 11 at the end of the upper housing 11 opposite to the hinge portion 13. The assembly work process of the upper housing | casing 11 is not restricted to the example mentioned above, You may include arbitrary processes.

FIG. 6 c is a bottom view of the first bumper 16. FIG. 6 d is a left side view of the first bumper 16. FIG. 6 e is a right side view of the first bumper 16. FIG. 6 f is a rear view of the first bumper 16.

  The first bumper 16 has, for example, a substantially C shape. The C-shaped inner peripheral surface 17 faces the side surface of the upper housing 11. Hereinafter, the inner peripheral surface 17 of the first bumper 16 is also referred to as a core-side surface of the first bumper 16. The C-shaped outer peripheral surface constitutes a part of the external surface of the electronic device 10. Hereinafter, the outer peripheral surface of the first bumper 16 is also referred to as a cavity-side surface of the first bumper 16. For example, each of the inner peripheral surface 17 and the outer peripheral surface of the first bumper 16 may include one or more planes and one or more curved surfaces. The inner peripheral surface 17 of the first bumper 16 may have a shape that contacts the side surface of the upper housing 11. The first bumper 16 includes a first locking portion 18, a second locking portion 19, and an ear portion 20 that protrude from the inner peripheral surface 17. The numbers of the first locking portions 18, the second locking portions 19, and the ear portions 20 of the first bumper 16 may be arbitrarily determined. In the example illustrated in FIG. 6, the first bumper 16 includes four first locking portions 18, two second locking portions 19, and one ear portion 20.

  The first locking portion 18 has a locking shape for locking to the upper housing 11 at a tip portion protruding from the inner peripheral surface 17, for example. The locking shape may include, for example, a hook shape 18a. The first locking portion 18 having the flange shape 18a is locked to the side wall of the upper housing 11 from the inside of the upper housing 11 as described later. When the first locking portion 18 is locked to the side wall of the upper housing 11, the first locking portion 18 is reduced from coming off the upper housing 11. For example, the four first locking portions 18 may be provided apart along the circumferential direction of the inner peripheral surface 17. For example, two first locking portions 18 may be provided near both ends in the circumferential direction of the inner peripheral surface 17.

  The 2nd latching | locking part 19 is the plate shape which protruded from the internal peripheral surface 17, for example. For example, the direction parallel to the plate-shaped surface of the second locking portion 19 and the circumferential direction of the inner peripheral surface 17 may substantially coincide. The distal end portion of the second locking portion 19 is inserted into a groove portion provided on the side surface of the front case 14 as will be described later. The second locking portion 19 has a locking shape for locking to the upper housing 11 at a root portion protruding from the inner peripheral surface 17, for example. The locking shape may include a through hole 19a, for example. As shown in FIG. 5, a protruding portion 15 a protruding from the surface of the rear case 15 facing the front case 14 is inserted into the through hole 19 a of the second locking portion 19. The 2nd latching | locking part 19 is latched by the protrusion part 15a of the rear case 15 penetrated by the through-hole 19a. Since the second locking portion 19 is locked to the protruding portion 15 a of the rear case 15, it is possible to reduce the removal from the upper housing 11. For example, the two second locking portions 19 may be provided apart along the circumferential direction of the inner peripheral surface 17. For example, two second locking portions 19 may be provided near the center of the inner peripheral surface 17 in the circumferential direction.

  The ear | edge part 20 is the plate shape which protruded from at least one part in the circumferential direction of the internal peripheral surface 17, for example. For example, the direction parallel to the plate-shaped surface of the ear portion 20 and the circumferential direction of the inner peripheral surface 17 may substantially coincide. The ear portion 20 may protrude from the central portion of the inner peripheral surface 17 in the circumferential direction. One surface of the tab shape of the ear portion 20 constitutes a part of the external surface of the electronic device 10. Hereinafter, the one surface of the ear portion 20 is also referred to as a cavity-side surface of the ear portion 20. The other plate-shaped surface of the ear portion 20 faces a second surface opposite to the first surface facing the rear case 15 of the front case 14 as will be described later. Hereinafter, the other plate-shaped surface of the ear portion 20 is also referred to as a core-side surface of the ear portion 20.

  The ear portion 20 has a third locking portion 21 protruding from the rear side surface. The 3rd latching | locking part 21 has the latching shape for latching to the front case 14 in the front-end | tip part which protruded from the surface of the rear side of the ear | edge part 20, for example. The locking shape may include, for example, a hook shape 21a. The 3rd latching | locking part 21 which has the collar shape 21a is latched by the 4th latching | locking part provided in the 2nd surface of the front case 14 so that it may mention later. When the third locking portion 21 is locked to the fourth locking portion of the front case 14, it is possible to reduce the lifting of the ear portion 20 from the front case 14. In the example shown in FIG. 6, the third locking portion 21 extends to the inner peripheral surface 17, but may be provided away from the inner peripheral surface 17.

  The front case 14 will be described in detail with reference to FIG. FIG. 7 a shows a first surface facing the rear case 15 at the tip of the front case 14. Hereinafter, the first surface of the front case 14 is also referred to as a core-side surface of the front case 14. FIG. 7 b shows a second surface opposite to the first surface at the front end portion of the front case 14. Hereinafter, the second surface of the front case 14 is also referred to as a cavity-side surface of the front case 14.

  As shown in FIG. 7 a, the front case 14 has a notch 23 in a part of the side wall 22 protruding from the core-side surface of the front case 14. The side wall 22 of the front case 14 may constitute at least a part of the side wall of the upper housing 11, for example. The notch 23 is provided corresponding to the first locking portion 18 of the first bumper 16 described above. In the example shown in FIG. 7a, there are four notches 23 corresponding to the four first locking portions 18, respectively. As will be described later, when the first bumper 16 is temporarily fixed to the front case 14, the root portion of each first locking portion 18 of the first bumper 16 is disposed in each notch 23 of the front case 14. In a state where the upper casing 11 is assembled, the hook shape 18 a of the first locking portion 18 of the first bumper 16 is locked to the side wall of the upper casing 11 from the inside of the upper casing 11.

  The front case 14 has a first wall portion 24 that surrounds at least a partial region of the core-side surface. The first wall portion 24 has a shape corresponding to the second wall portion surrounding at least a partial region of the surface of the rear case 15 facing the front case 14. In a state where the upper housing 11 is assembled, the first wall portion 24 of the front case 14 and the second wall portion of the rear case 15 are in close contact with each other via a waterproof member. The waterproof member may include, for example, a waterproof double-sided tape and an elastic member. The waterproof member may be provided integrally with the first wall portion 24 or the second wall portion, or may be provided as a separate body.

In the example shown in FIG. 7, there are two groove portions 25 corresponding to the two second locking portions 19. The groove portion 25 extends in the depth direction to, for example, the first wall portion 24 present at the tip portion of the front case 14. The bottom surface of the groove portion 25 is located between the outer peripheral surface and the inner peripheral surface of the first wall portion 24. As will be described later, when the first bumper 16 is temporarily fixed to the front case 14, the distal end portions of the respective second locking portions 19 of the first bumper 16 are inserted into the respective groove portions 25 of the front case 14.

  The front case 14 has a fourth locking portion 26 on the cavity-side surface of the tip portion. The 4th latching | locking part 26 is provided corresponding to the 3rd latching | locking part 21 of the 1st bumper 16 mentioned above. In the example shown in FIG. 7, there are three fourth locking portions 26 corresponding to the three third locking portions 21, respectively. The fourth locking portion 26 has a groove shape extending from the side surface of the front end portion of the front case 14, for example, in the substantially same direction as the depth direction of the groove portion 25. The cross section of the groove shape is a shape corresponding to the flange shape 21 a of the third locking portion 21 of the first bumper 16. As will be described later, when the first bumper 16 is temporarily fixed to the front case 14, the third locking portions 21 of the first bumper 16 are inserted into the fourth locking portions 26 of the front case 14.

  With reference to FIG. 5, the process of temporarily fixing the first bumper 16 to the front case 14 will be described. For example, the assembly operator inserts each second locking portion 19 of the first bumper 16 into each groove portion 25 of the front case 14. The assembly operator inserts each third locking portion 21 of the first bumper 16 into each fourth locking portion 26 of the front case 14. The assembling worker arranges the root portion of each first locking portion 18 of the first bumper 16 in each notch portion 23 of the front case 14.

  In a state where the first bumper 16 is temporarily fixed to the front case 14, at least a part of the through hole 19a formed in the base portion of each second locking portion 19 of the first bumper 16 is as shown in FIG. The front case 14 is exposed from the core side. An operator inserts each protrusion 15a of the rear case 15 into each through hole 19a, and locks the front case 14 and the rear case 15. An assembly worker fixes the front case 14 and the rear case 15 using a fastening member.

  In the upper housing 11 assembled in this way, the first locking portion 18 of the first bumper 16 passes through a hole provided in the side surface of the upper housing 11 and extends to the inside of the upper housing 11. ing. At least a part of the hole may include a notch 23 of the front case 14. The first locking portion 18 is locked to the side wall of the upper housing 11 from the inside of the upper housing 11. The second locking portion 19 of the first bumper 16 is locked to the protruding portion 15 a of the rear case 15 inserted through the through hole 19 a of the second locking portion 19. The third locking portion 21 of the first bumper 16 is locked to the fourth locking portion 26 of the front case 14.

  The lower housing 12, the second bumper 27, and the third bumper 28 may be assembled in the same manner as the upper housing 11 and the first bumper 16 described above. For example, the lower housing 12 may include a front case and a rear case, similarly to the upper housing 11. Each of the second bumper 27 and the third bumper 28 may have, for example, a substantially C shape or a substantially L shape. Each of the second bumper 27 and the third bumper 28 includes one or more having the same configuration as at least one of the first locking portion 18, the second locking portion 19, and the third locking portion 21 described above. A locking portion may be provided.

  As described above, the electronic device 10 according to an embodiment of the present disclosure includes the upper housing 11 including the front case 14 and the rear case 15 and the first bumper 16. The first locking portion 18 of the first bumper 16 extends to the inside of the upper housing 11 and is locked to the side wall of the upper housing 11 from the inside of the upper housing 11. As for the 2nd latching | locking part 19 of the 1st bumper 16, while a front-end | tip part is inserted in the groove part 25 of the front case 14, it is latched by the protrusion part 15a of the rear case 15 penetrated by the through-hole 19a of the root part.

For example, as shown in FIG. 8, a relatively large space for disposing the first locking portion 18 in the internal space excluding the waterproof space of the upper housing 11 is used for locking via the first locking portion 18. Is required. On the other hand, a groove 25 may be provided on the side surface of the front case 14 for locking via the second locking portion 19. For this reason, the space required in the internal space excluding the waterproof space of the upper housing 11 is relatively small for locking via the second locking portion 19. According to the electronic device 10, for example, the first bumper 16 can be installed in a space-saving manner by arranging the second locking portion 19 in a location where a space large enough for locking via the first locking portion 18 cannot be secured. It can be fixed to the upper housing 11. For this reason, the enlargement of the electronic device 10 resulting from mounting of a bumper is reduced.

  For example, in an electronic device that requires waterproof performance, both downsizing of the electronic device itself and expansion of the waterproof region are desired. According to an embodiment of the present disclosure, the groove portion 25 necessary for locking the second locking portion 19 of the first bumper 16 can be provided in the first wall portion 24 that defines the waterproof region of the electronic device 10. . Therefore, even when the first wall portion 24 is provided in a region near the side surface of the upper housing 11, the second locking portion 19 can be locked in the region. For this reason, the configuration of the electronic device 10 according to an embodiment of the present disclosure is particularly suitable for an electronic device that requires waterproof performance, for example.

  As described above, the electronic device 10 according to the embodiment of the present disclosure has the first bumper 16, the second bumper 27, and the third bumper at a place having a high probability of first colliding with the ground when falling in the open state. And a bumper 28. According to such a configuration, the durability of the electronic device 10 is improved without providing a bumper at a location where the probability of first colliding with the ground when the electronic device 10 falls in the open state is low. For example, it is not necessary to cover each side surface of the upper casing 11 and the lower casing 12 with a bumper over the entire circumference. For this reason, the enlargement of the electronic device 10 resulting from mounting of a bumper is reduced.

  Although the present invention has been described based on the drawings and embodiments, it should be noted that those skilled in the art can easily make various changes and modifications based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions and the like included in each means and each step can be rearranged so as not to be logically contradictory, and a plurality of means and steps can be combined into one or divided. .

  In the above-described embodiment, the configuration in which the protruding portion 15a is formed integrally with the rear case 15 has been described. However, for example, a member that performs the same function as the protruding portion 15a may be provided separately from the rear case 15. As the member, for example, a metal columnar member is conceivable. Specifically, the assembly operator may temporarily fix the first bumper 16 to the front case 14 and then insert the member into the through hole 19 a of the second locking portion 19 of the first bumper 16. For example, both ends of the member may be fitted into holes provided in the front case 14 and the rear case 15, respectively. Such a configuration also reduces the increase in size of the electronic device 10 due to the mounting of the bumper, as in the above-described embodiment.

For example, the two first bumpers may cover two corners at the end of the upper casing 11 opposite to the lower casing 12 side.

  In the embodiment described above, the configuration in which the electronic device 10 includes the two second bumpers 27 has been described. However, the electronic device 10 may include one or three or more second bumpers. Each of the one or more second bumpers covers at least a part of the end of the upper casing 11 opposite to the lower casing 12 side. For example, one second bumper may cover two corners at the end of the lower housing 12 opposite to the upper housing 11 side.

  In the above-described embodiment, the configuration in which the electronic device 10 includes the two third bumpers 28 has been described. However, the electronic device 10 may include one or more third bumpers. Each of the one or more third bumpers covers at least a part of the end of the upper housing 11 on the lower housing 12 side. For example, one third bumper may cover two corners at the end of the lower housing 12 on the upper housing 11 side.

  In the embodiment described above, the configuration in which the electronic device 10 includes the window portion 29 in the upper housing 11 has been described. However, the window 29 may be provided in the lower housing 12. For example, a camera module provided inside the lower housing 12 may image light incident from the window 29 provided in the lower housing 12.

  In the above-described embodiment, each second bumper 27 and each third bumper 28 may protrude outward from the rear side surface of the lower housing 12. With this configuration, for example, when the electronic device 10 is left stationary with the rear surface of the lower housing 12 facing downward, the surface on which the electronic device 10 is stationary and the rear surface of the lower housing 12 are Collision is reduced. For this reason, the durability of the electronic device 10 is further improved.
