[0137] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with the present disclosure. On the contrary, they are only examples of the devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0138] An embodiment of the first aspect of the present disclosure provides an installation structure for a terminal accessory, and the installation structure 100 includes:

[0139] The first housing 220;

[0140] The first bracket 110;

[0141] The first limiting member 230, connected to the first housing 220;

[0142] The gear 120 has a first tooth 121 and a rotating shaft 122 at both ends, and the rotating shaft 122 connects the first bracket 110 and the fitting 300;

[0143] The driving member is mounted on the first housing 220 and connected to the first bracket 110, and is used to drive the first bracket 110 to drive the gear 120 to move in a preset direction;

[0144] The linkage member 140 includes a first part 141 and a second part. The first part 141 has a second tooth meshing with the first tooth 121, and the second part has a limiting hole 142 for accommodating the first limiting member 230;

[0145] The first bracket 110 has at least a first position and a second position along the preset direction;

[0146] When the first bracket 110 is in the first position, the first limiting member is at one end of the limiting hole close to the first part, restricting the linkage member from moving in the direction opposite to the preset direction;

[0147] When the first bracket 110 is in the second position, the first limiting member 230 is at the other end of the limiting hole 142 away from the first part 141, restricting the linkage member 140 from moving in the preset direction.

[0148] As Figure 3 、 Figure 9 、 Figure 17 、 Figure 20 、 Figure 23 、 Figure 26 、 Figure 29 、 Figure 32 and Figure 60 As shown in, the first housing 220 serves as a fixing member for carrying components such as the first bracket 110, the driving member, and the linkage member 140.

[0149] When applied to the terminal 200, the first housing 220 can be the rear case of the terminal 200, and the mounting structure 100 is a part of the terminal 200. Alternatively, the first housing 220 is an external housing independent of the terminal 200. For example, the first housing 220 is a protective case, and the protective case can be mounted on the rear case of the terminal 200.

[0150] The first bracket 110 is movable relative to the first housing 220. The moving directions include moving along a preset direction and moving along a direction opposite to the preset direction.

[0151] As Figures 1 to 6 , and Figure 19 shown, the first position is the position when there is no relative movement between the first bracket 110 and the first housing 220, and can also be referred to as the initial position. The second position is the position where the first bracket 110 is located when a relative displacement occurs between the first bracket 110 and the first housing 220 and this relative displacement is at its maximum.

[0152] In the embodiment of the present disclosure, when the driving member is used to drive the first bracket to move along the preset direction, the first bracket drives the accessory to move along the preset direction through the gear, and the gear also drives the linkage to move along the preset direction through meshing with the linkage, realizing the change of the accessory at different positions driven by the first bracket through the gear. Using this change in position, the accessory can be hidden inside the terminal housing when not in use, or the accessory can be ejected out of the terminal housing when the accessory is needed. When the accessory is hidden inside the terminal housing, the terminal housing has a protective effect on the accessory.

[0153] According to some other alternative embodiments, as Figure 65 shown, the first bracket 110 has an avoidance hole 112;

[0154] The rotating shaft 122 is located inside the avoidance hole 112;

[0155] The first bracket 110 further has a third position along the preset direction, and the third position is located between the first position and the second position;

[0156] When the first bracket 110 is located at the first position, the gear 120 is located at the first end of the first part 141, and the accessory 300 has a first posture;

[0157] When the first bracket 110 is located at the third position, the gear 120 is located at the first end of the first part 141, and the first limiting member 230 is located at the other end of the limiting hole 142 away from the first part, and the accessory 300 has the first posture;

[0158] When the first bracket 110 is located at the second position, the gear 120 is located at the second end of the first part 141, and the accessory 300 has a second posture; wherein, the second end is the opposite end of the first end, and the second posture is the posture after the first posture rotates a preset angle.

[0159] There are multiple positions between the first position and the second position, where the third position is one of them. The first bracket 110 is located at the third position. The linkage 140 cannot continue to move in the preset direction. However, under the driving force of the driving member, the first bracket 110 continues to drive the gear 120 to move in the preset direction towards the second position. Different from the movement process from the first position to the third position, when the first bracket 110 moves from the third position to the second position, the gear 120 generates a linear displacement in the preset direction while rotating. At the same time, the rotating shaft 122 of the gear 120 drives the accessory 300 to rotate, realizing the transformation of the accessory 300 from the first posture to the second posture.

[0160] Without limitation, the preset angle is 60°, 90°, 180°, etc.

[0161] During the movement in the preset direction, taking the movement of the first bracket 110 from the first position through the third position to the second position as an example, the installation structure will be further explained.

[0162] The first bracket 110 is located at the first position. If the driving member does not provide driving force or the driving force provided by the driving member is overcome, the first bracket 110 will remain at the first position, as Figure 3 , Figure 20 , Figure 23 and Figure 65 shown. Part of the gear 120 is located at the first end of the first part 141. If the driving member provides a driving force towards the preset direction, the first bracket 110 leaves the first position. At this time, the first bracket 110 drives the gear 120 to move in the preset direction, and the gear 120 drives the linkage 140 to also move in the preset direction. The first limiting member 230 does not restrict the movement of the linkage 140.

[0163] When the first bracket 110 moves to the third position, part of the gear 120 is still located at the first end of the first part 141. However, at this time, the end of the limiting hole 142 away from the first part 141 abuts against the first limiting member 230, and the first limiting member 230 begins to restrict the linkage 140 from continuing to move in the preset direction.

[0164] When the first bracket 110 moves from the third position to the second position, since the first bracket 110 and the gear 120 are not restricted, under the driving force of the driving member, the first bracket 110 will still drive the gear 120 to continue to move in the preset direction. At this time, because the linkage 140 cannot move, the gear 120 will rotate and move relative to the first part 141 of the linkage 140 and drive the accessory 300 to rotate. When the first bracket 110 reaches the second position, part of the gear 120 moves to the second end of the first part 141, and the accessory 300 completes the transformation from the first posture to the second posture. The driving member can stop driving, or the first bracket 110 stops continuing to move in the preset direction.

[0165] In practical applications, taking the terminal 200 as a mobile phone and the accessory 300 as a flash light as an example, when the preset angle is 180°, if the first posture means that the light-emitting surface of the flash light faces the display screen 260 side of the terminal 200, then the second posture means that the light-emitting surface of the flash light faces the back shell direction of the terminal 200, realizing that one flash light can be used to supplement light for both the front camera 270 and the rear camera 210 at the same time, without separately equipping flash lights for the front camera 270 and the rear camera 210 respectively, reducing the number of flash lights and being beneficial to saving the space of the terminal 200.

[0166] When applied to the terminal 200, the first position can be the position where the first bracket 110 is hidden inside the shell of the terminal 200. At this time, the accessory 300 generally will also be hidden inside the shell of the terminal 200 to protect the accessory 300. The second position can be the highest position where the first bracket 110 exposes outside the shell of the terminal 200. At this time, the accessory 300 will be completely exposed outside the terminal 200.

[0167] The avoidance hole 112 on the first bracket 110 is used to avoid the rotating shaft 122 of the gear 120, so that the first bracket 110 can drive the gear 120 to move along the preset direction or the direction opposite to the preset direction through the contact between the hole wall of the avoidance hole 112 and the rotating shaft 122, but does not rotate with the rotation of the gear 120.

[0168] The avoidance hole 112 can be a closed hole, such as a circular hole, an oval hole or a hexagonal hole, etc., or can be an unclosed hole. For example, the avoidance hole 112 is a semi-circular hole or a rectangular notch.

[0169] As Figure 65 shown, the avoidance hole 112 on the first bracket 110 is a rectangular notch, and the hole wall of the avoidance hole 112 abuts against the rotating shaft 122.

[0170] Compared with a relatively closed hole, when the avoidance hole 112 is an unclosed hole, the rotating shaft 122 of the gear 120 can be assembled with the first bracket 110 from the axial direction or the radial direction, making the assembly of the first bracket 110 and the gear 120 more flexible.

[0171] The first limiting member 230 is fixed on the first housing 220 and can be regarded as a whole with the first housing 220. The first limiting member 230 and the first housing 220 can be integrally formed by injection molding or machining and other methods.

[0172] Without limitation, as Figure 3 、 Figure 23 、 Figure 29 、 Figure 60 and Figure 66As shown, the first limiting member 230 is a cylindrical structure protruding from the first housing 220 towards the first bracket 110, and the first limiting member 230 is inserted into the limiting hole 142 of the linkage member 140. During the movement of the linkage member 140, the first limiting member 230 will be located at different positions in the limiting hole 142.

[0173] In practical applications, taking the terminal 200 as a mobile phone for example, assume that the preset direction is the direction towards the top of the mobile phone, that is, the upward direction. As Figure 3 , when the first limiting member 230 is located at one end of the limiting hole 142 close to the first part 141, it means that the first limiting member 230 is located at the top of the limiting hole 142. When the first limiting member 230 is located at the other end of the limiting hole 142 away from the first part 141, it means that the first limiting member 230 is located at the bottom of the limiting hole 142. When the first limiting member 230 is located at the top of the limiting hole 142, it can prevent the linkage member 140 from continuing to move downward; when the first limiting member 230 is located at the bottom of the limiting hole 142, it can prevent the linkage member 140 from continuing to move upward. When the first bracket 110 is located between the top and the bottom of the limiting hole 142, the linkage member 140 can move upward or downward.

[0174] The length of the limiting hole 142 is approximately equal to the maximum distance that the linkage member 140 can move.

[0175] As Figure 3 shown, the limiting hole 142 is generally strip-shaped and is generally parallel to the preset direction.

[0176] When the first bracket 110 drives the gear 120 to move in the preset direction through the hole wall of the avoidance hole 112, the first tooth 121 drives the linkage member 140 to move in the preset direction by meshing with the second tooth on the first part 141 of the linkage member 140 until the first limiting member 230 restricts the linkage member 140 from continuing to move in the preset direction.

[0177] The driving member can be driven by electricity or by mechanical force.

[0178] In some embodiments, the driving member includes a motor and a lead screw assembly. The lead screw assembly is respectively connected to the driving shaft of the motor and the first bracket 110. The lead screw assembly is used to convert the rotational motion of the motor into a linear motion, thereby realizing that the lead screw assembly drives the first bracket 110 to move in the preset direction.

[0179] In some embodiments, the driving member includes: a first elastic member 130;

[0180] The first bracket 110 is located at the first position, and the first elastic member 130 is in an elastically deformed state storing the first elastic force; wherein, the first elastic force is used to drive the first bracket 110 to move in the preset direction.

[0181] The first elastic force stored by the first elastic member 130 can also drive the first bracket 110 to move in a preset direction.

[0182] In practical applications, one end of the first elastic member 130 is fixed to the first housing 220, and the other end of the first elastic member 130 is fixed to the first bracket 110. This structure that uses the first elastic force to drive the first bracket 110 to move can reduce the power consumption of the installation structure and is also more conducive to reducing the production cost of the installation structure.

[0183] According to some other optional embodiments, the first elastic member 130 includes a tension spring 131 and / or a compression spring 132.

[0184] The first elastic member 130 can be a compression elastic member, or a tension spring 131. Alternatively, the first elastic member 130 can include both a compression spring 132 and a tension spring 131.

[0185] As Figure 3 、 Figure 23 、 Figure 29 and Figure 60 shown, the first elastic member 130 includes two compression springs 132 and two tension springs 131.

[0186] According to some other optional embodiments, as Figure 3 、 Figure 20 、 Figure 23 、 Figure 29 and Figure 60 shown, the linkage member 140 further has a receiving hole 143, and the receiving hole 143 is located between the first portion 141 and the second portion;

[0187] The installation structure 100 further includes:

[0188] A second limiting member 150, connected to the first bracket 110 and at least partially located in the receiving hole 143;

[0189] When the first bracket 110 is in the first position, as Figure 3 、 Figure 20 and Figure 23 shown, the second limiting member 150 is located at one end of the receiving hole 143 close to the second portion, restricting the rotation shaft 122 and the first portion 141 from disengaging in a direction opposite to the preset direction;

[0190] When the first bracket 110 is in the second position, as Figure 29 shown, the second limiting member 150 is located at the other end of the receiving hole 143 away from the second portion, restricting the rotation shaft 122 and the first portion 141 from disengaging in the preset direction.

[0191] If the preset direction is the upward direction, the second limiting member 150 is located at one end of the receiving hole 143 close to the second part, which means the second limiting member 150 is located at the bottom end of the receiving hole 143. As shown in Figure 3 and Figure 20 and Figure 23 shown, at this time, the first bracket 110 may be located at the first position, the third position, or any position between the first position and the third position.

[0192] The second limiting member 150 is located at the other end of the receiving hole 143 away from the second part, which means the second limiting member 150 is located at the top end of the receiving hole 143. As shown in Figure 29 shown, at this time, the first bracket 110 is located at the second position.

[0193] As shown in Figure 60 shown, when the second limiting member 150 is located between the top end and the bottom end of the receiving hole 143, the first bracket 110 is located between the third position and the second position.

[0194] Since the second limiting member 150 is fixed on the first bracket 110, if there is a large frictional force between the second limiting member 150 and the first limiting member 230, when the first bracket 110 moves from the first position to the third position, in addition to driving the linkage member 140 to move through the rotating shaft 122, the first bracket 110 can also utilize the frictional force between the second limiting member 150 and the hole wall of the receiving hole 143 to drive the linkage member 140 to move along the preset direction.

[0195] The cooperation between the receiving hole 143 and the second limiting member 150 not only helps to ensure that the gear 120 and the first part 141 of the linkage member 140 remain in the meshing state, but also helps to further ensure the linkage between the first bracket 110 and the linkage member 140.

[0196] When the first bracket 110 returns from the second position to the first position, the first bracket 110 can also drive the linkage member 140 to move in the direction opposite to the preset direction through the abutment between the second limiting member 150 and the hole wall of the receiving hole 143.

[0197] According to some other alternative embodiments, as shown in Figures 7 to 11 shown, the first bracket 110 has a protrusion 111, and the protrusion 111 protrudes in a direction away from the first housing 220;

[0198] The mounting structure 100 further includes:

[0199] A button 190, including a limiting portion 191 and a triggering portion 192 for the acting pressing force, and the limiting portion 191 has a limiting surface 1911 for docking with the protrusion 111;

[0200] The shaft rod 193 is installed on the first housing 220, connected to the button 190, and located between the limiting portion 191 and the triggering portion 192;

[0201] The second elastic member 170 has two ends respectively connected to the first housing 220 and the limiting portion 191;

[0202] When the first bracket 110 is in the first position, the limiting surface 1911 abuts against the protrusion 111, restricting the first bracket 110 from moving along the preset direction; the second elastic member 170 is in an elastically deformed state storing the second elastic force; wherein, the second elastic force is used to maintain the state where the limiting surface 1911 abuts against the protrusion 111;

[0203] When the first bracket 110 is in the second position, the limiting surface 1911 is disengaged from the protrusion 111.

[0204] Take the structure as shown in Figure 9 For example, when the driving member includes the first elastic member 130, through the second elastic force provided by the second elastic member 170, and the abutment of the limiting surface 1911 of the limiting portion 191 of the button 190 against the protrusion 111, the first elastic force of the first elastic member 130 can be overcome to restrict the first bracket 110 from moving along the preset direction, so that the first bracket 110 is maintained in the first position.

[0205] When a pressing force acts on the triggering portion 192, the second elastic force of the second elastic member 170 can be overcome, causing the button 190 to rotate clockwise around the shaft rod 193, the limiting surface 1911 to disengage from the protrusion 111, and the first bracket 110 to get rid of the limitation of the button 190 and move along the preset direction under the drive of the driving member. At this time, when the pressing force is withdrawn, under the action of the second elastic member 170, the driving member will rotate counterclockwise. When the first bracket 110 has not returned to the first position, due to the obstruction of the first bracket 110, the limiting portion 191 will abut against the first bracket 110. If the first bracket 110 returns to the first position, under the action of the second elastic force of the second elastic member 170, the limiting surface 1911 of the limiting portion 191 will abut against the protrusion 111 again, and the first bracket 110 and the button 190 will return to the Figure 9 shown state.

[0206] According to some other alternative embodiments, the mounting structure further includes:

[0207] The second housing 180 is installed on the first housing 220, and the first bracket 110 is located between the first housing 220 and the second housing 180;

[0208] The second housing 180 has a through hole 1801, and the trigger portion 192 is located within the through hole 1801.

[0209] As Figure 9 and Figure 14 shown, the first bracket 110 moves within the accommodation space jointly formed by the second housing 180 and the first housing 220. A part of the second housing 180 can serve as a pressing block 181 to restrict the first bracket 110 from disengaging from the accommodation space and ensure the stability of the movement of the first bracket 110.

[0210] In some embodiments, as Figure 9 shown, the mounting structure 100 further includes a covering member 182, and the covering member 182 is located between the second housing 180 and the key 190. The covering member 182 can cover internal structures such as the second elastic member 170 and the limiting portion 191, further ensuring the neatness of the appearance of the mounting structure.

[0211] According to some other alternative embodiments, as Figure 3 , Figure 23 , Figure 29 , Figure 60 , Figures 66 to 69 , Figures 71 to 72 , and Figure 74 shown, the mounting structure further includes:

[0212] A guide member 240, located on the first housing 220, and the guide member 240 includes a first inclined surface 241;

[0213] A sliding member 161, connected to the linkage member 140, and includes a second inclined surface 1611 that abuts against the first inclined surface 241;

[0214] A third elastic member 164, with two ends respectively connected to the linkage member 140 and the sliding member 161, or with two ends respectively connected to the first housing 220 and the guide member 240;

[0215] As Figure 29 shown, when the first bracket 110 is in the second position, the second inclined surface 1611 abuts against the first inclined surface 241;

[0216] As Figure 3 shown, when the first bracket 110 is in the first position, the second inclined surface 1611 is separated from the first inclined surface 241, and the third elastic member 164 is in an elastically deformed state.

[0217] When the first bracket 110 returns from the second position to the first position, by the abutment of the first inclined surface 241 and the second inclined surface 1611, the resistance of the linkage 140 moving in the direction opposite to the preset direction can be increased, so that the gear 120 part of the gear 120 can move from the second end of the first part 141 to the first end, and the fitting 300 is restored from the second posture to the first posture.

[0218] As Figure 29 and Figure 66 shown, when the first bracket 110 drives the linkage 140 to move in the direction opposite to the preset direction, the linkage 140 will drive the second inclined surface 1611 of the slider 161 to move along the first inclined surface 241 of the guide 240. The force exerted by the slider 161 on the first inclined surface 241 through the second inclined surface 1611 is decomposed by the first inclined surface 241 into two component forces in different directions. One is the lateral component force offset by the compression of the third elastic member 164; the other is the vertical separation that hinders the linkage 140 from moving in the direction opposite to the preset direction, realizing the rotation of the gear 120.

[0219] During the movement of the second inclined surface 1611 along the first inclined surface 241, the degree of compression of the third elastic member 164 gradually increases, and the resistance received by the linkage 140 also becomes greater and greater.

[0220] In practical applications, the third elastic member 164 can be connected to the linkage 140 and the slider 161 respectively. At this time, the third elastic member 164 can drive the slider 161 to expand and contract; Figures 66 to 74 Exemplarily shown is a partial structural schematic diagram of the installation structure when the third elastic member 164 can be connected to the linkage 140 and the slider 161 respectively.

[0221] Alternatively, the third elastic member 164 can also be connected to the first housing 220 and the guide 240 respectively. At this time, the third elastic member 164 can drive the guide 240 to expand and contract.

[0222] In some embodiments, the installation structure further includes a slider cover 162 and a third limiting member 163. Among them, the slider 161 is located between the slider cover 162 and the linkage 140. The third elastic member 164 is connected to the slider 161 and / or the linkage 140 respectively. The slider cover 162 has an adjustment hole 165. The third limiting member 163 is installed on the slider 161 and passes through the adjustment hole 165. When the third elastic member 164 is in the elastic deformation state and the non-elastic deformation state, the third limiting member 163 is located at both ends of the adjustment hole 165 respectively to limit the expansion and contraction range of the third elastic member 164 and protect the elastic force of the third elastic member 164.

[0223] Without limitation, the included angle between the second inclined surface 1611 and the horizontal plane is less than 45°. Both the second inclined surface 1611 and the first inclined surface 241 are relatively smooth and have small frictional forces, and can slide when contacting the first inclined surface 241 of the guiding member 240; under the action of the third elastic member 164, the sliding member 161 reaches moment balance after contacting the first inclined surface 241 of the guiding member 240.

[0224] Taking the preset direction as the upward direction as an example. When an external force pushes the flash downward (i.e., during the process of the first bracket 110 returning from the second position to the first position), a part of the driving force is offset by the first elastic member 130, and the other part is decomposed into a component force perpendicular to the inclined surface and a component force along the downward direction of the inclined surface; the component force perpendicular to the inclined surface is offset; the component force along the downward direction of the inclined surface is offset by the frictional force between the two inclined surfaces. Only when the driving force downward on the flash reaches a certain threshold can the first bracket 110 move downward; the automatic locking function is achieved according to this principle. When there is a small external force, or vibration shock, etc., even if the first elastic member 130 undergoes elastic deformation, it will not cause the overall flash to move downward and oscillate; affecting the performance and user experience.

[0225] According to some other alternative embodiments, the guiding member 240 further includes: a first guiding surface 242 adjacent to the first inclined surface 241; the first guiding surface 242 is parallel to the preset direction;

[0226] The sliding member 161 further includes a second guiding surface 1612 docked with the first guiding surface 242;

[0227] When the first bracket 110 is in the first position, and when the first bracket 110 is between the first position and the second position, the first guiding surface 242 abuts against the second guiding surface 1612.

[0228] As Figure 23 、 Figure 29 and Figure 66 shown, the second guiding surface 1612 is used to guide the linkage member 140 to move in the preset direction or in the direction opposite to the preset direction, ensuring the stability of the linkage member 140 during the movement process.

[0229] An embodiment of the second aspect of the present disclosure provides an accessory 300 module, and the module includes:

[0230] The mounting structure according to the embodiment of the first aspect;

[0231] An accessory 300, connected to the rotating shaft 122 of the mounting structure.

[0232] In the embodiments of the present disclosure, when the driving member drives the first bracket 110 to move in a preset direction, the first bracket 110 drives the accessory 300 to move in the preset direction through the gear 120, and the gear 120 also drives the linkage member 140 to move in the preset direction through meshing with the linkage member 140. When the first limiting member 230 is located at one end of the limiting hole 142 away from the first part 141 of the linkage member 140, the first limiting member 230 will limit the linkage member 140 from continuing to move in the preset direction. However, affected by the driving force of the driving member, the first bracket 110 will still drive the gear 120 to rotate relative to the first part 141 of the linkage member 140, realizing the transformation of the accessory 300 from the first posture to the second posture. By using the transformation from the first posture to the second posture, the function of the accessory 300 can be used in different directions of the terminal 200, serving multiple purposes with one component. There is no need to set multiple accessories 300 in different directions of the terminal 200, reducing the number of accessories 300, which is beneficial to saving the space of the terminal 200 and realizing the thin and light of the terminal 200. Moreover, the first bracket 110 of the accessory 300 drives the accessory 300 to first move in the preset direction and then rotate through the gear 120. This function of moving in the preset direction can also hide the accessory 300 in the terminal 200, playing a protective role for the accessory 300.

[0233] According to some other optional embodiments, the accessory 300 includes at least one of the following:

[0234] A structured light component, a camera or a light sensor; wherein, the structured light component includes a flash.

[0235] The light sensor can be an ambient light sensor for sensing the ambient light intensity. Alternatively, the light sensor can be an infrared light sensor.

[0236] The camera can be a depth camera module based on TOF (Time Of Flight), but is not limited thereto.

[0237] According to some other optional embodiments, the accessory 300 includes:

[0238] A third housing, connected to the rotating shaft 122 of the mounting structure, having an accommodation cavity;

[0239] A circuit board 340, located in the accommodation cavity;

[0240] Functional devices, located in the accommodation cavity and electrically connected to the circuit board 340;

[0241] A connecting wire 310, electrically connecting the circuit board and the central processing unit of the terminal 200 respectively; wherein, the connecting wire 310 is wound around the rotating shaft 122.

[0242] Such as Figures 15 to 17As shown, the connecting wire 310 wound around the rotating shaft 122 of the gear 120 can increase the length of the connecting wire 310 to adapt to the rotation of the gear 120.

[0243] Without limitation, the connection line 310 includes a flexible printed circuit board.

[0244] The accessory 300 takes a flash as an example. Figures 12 to 14 As shown. The third housing of the flashlight may be composed of a third bracket 320, a lampshade 360 and a cover plate 330, wherein the third bracket 320 constitutes the side wall of the accommodating cavity, the cover plate 330 constitutes the bottom of the accommodating cavity, and the lampshade 360 covers the cover plate to constitute the top of the accommodating cavity. The circuit board 340 of the flashlight may be mounted on the cover plate 330. The functional components of the flashlight include a plurality of LED lamps 350, and the plurality of LED lamps 350 are electrically connected to the circuit board 340. The circuit board 340 may be a printed circuit board.

[0245] The third aspect of the present disclosure provides a terminal 200, wherein the terminal 200 includes:

[0246] The accessory 300 module described in the second aspect of the embodiment.

[0247] The terminal 200 includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a television or a wearable device.

[0248] In a specific example, the terminal 200 is a mobile phone, the accessory 300 is a flashlight, and the preset direction is upward. The maximum distance that the first bracket 110 moves upward (also called upward pop-up) is the total elevation, and the maximum distance that the first bracket 110 moves downward is the total return stroke. The installation structure is further described below by taking the upward pop-up process and the downward return process as examples.

[0249] The first bracket 110 is in an initial state, that is, the first bracket 110 is in a first position. Figure 1 , Figure 35 and Figure 37 shows a side view of the terminal 200 when the first bracket 110 is in the first position, Figure 7 , Figure 12 , Figure 15 , Figure 18 , Figure 33 and Figure 34 The structural schematic diagrams of the back side of the terminal 200 (ie, the side of the rear shell of the terminal 200) are respectively shown. Figure 36It shows a schematic structural diagram of the front side (i.e., the display screen side) of the terminal 200. The light-emitting surface of the flash faces the back side of the terminal 200 (i.e., the first posture), and is used to supplement light for the rear camera 210 of the terminal 200. It can be seen from this that when the first bracket 110 is in the first position, the top surface of the flash will not be higher than the top surface of the housing of the terminal 200. Even, the flash can be hidden inside the housing to reduce damage to the flash caused by collisions and the like.

[0250] As Figure 3 shown, the first bracket 110 is in the first position, the first limiting member 230 is located at the other end of the limiting hole 142 close to the first part 141, a part of the gear 120 is located at the first end of the first part 141, and the second limiting member 150 is located at the end of the receiving hole 143 close to the second part. The second guiding surface 1612 of the sliding member 161 contacts the bottom end of the first guiding surface 242 of the guiding member 240.

[0251] As Figures 7 to 11 shown, the first bracket 110 is in the first position, the limiting surface 1911 of the limiting part 191 of the button 190 abuts against the protrusion 111 on the first bracket 110, restricting the first elastic member 130 from driving the first bracket 110 to move upward.

[0252] After pressing the triggering part 192 of the button 190, the limiting surface 1911 of the limiting part 191 of the button 190 disengages from the protrusion 111 on the first bracket 110, and the first limiting member 230 drives the first bracket 110 to move upward.

[0253] As Figure 38 , and Figures 42 to 45 shown, the first bracket 110 is in the state of popping up 1 / 2 of the total elevation. At this time, the position where the first bracket 110 is located is between the first position and the second position. The light-emitting surface of the flash faces the back side of the terminal 200, the first limiting member 230 leaves the other end of the limiting hole 142 close to the first part 141, and moves upward about 1 / 2 of the total length of the limiting hole 142; a part of the gear 120 is located at the first end of the first part 141, and the second limiting member 150 is located at the end of the receiving hole 143 close to the second part. The second guiding surface 1612 of the sliding member 161 moves upward a part of the distance along the first guiding surface 242 of the guiding member 240, and the second guiding surface 1612 is located at approximately the middle position of the first guiding surface 242.

[0254] As Figures 21 to 36 , Figure 39 and Figures 46 to 49As shown, the first bracket 110 is in a state of popping up 2 / 3 of the total elevation (i.e., the first bracket 110 is in the third position). At this time, the position of the first bracket 110 is also between the first position and the second position. The light-emitting surface of the flash still faces the back of the terminal 200. Part of the gear 120 is still located at the first end of the first part 141, and the second limiting member 150 is still located at one end of the receiving hole 143 close to the second part. Different from the state of popping up 1 / 2 of the total elevation, the upward movement distance of the flash and the first bracket 110 is greater, and the first limiting member 230 is located at one end of the limiting hole 142 away from the first part 141, restricting the linkage member 140 from continuing to move upward. The second inclined surface 1611 of the sliding member 161 abuts against the first inclined surface 241 of the guiding member 240.

[0255] As Figure 40 , and Figures 50 to 53 shown, the first bracket 110 is in a state of popping up 5 / 6 of the total elevation. At this time, the position of the first bracket 110 is also between the first position and the second position. Part of the gear 120 is located between the first end and the second end of the first part 141. The flash rotates approximately 90°. The linkage member 140 and the sliding member 161 still maintain the same state as when the first bracket 110 is in a state of popping up 2 / 3 of the total elevation.

[0256] As Figures 27 to 32 , Figure 40 , Figure 41 , and Figures 54 to 57 shown, the first bracket 110 pops out completely, that is, the first bracket 110 is in the second position. At this time, the light-emitting surface of the flash faces the front of the terminal 200 (the second posture). Part of the gear 120 is located at the second end of the first part 141, and the second limiting member 150 is located at the other end of the receiving hole 143 away from the second part. The linkage member 140 and the sliding member 161 still maintain the same state as when the first bracket 110 is in a state of popping up 2 / 3 of the total elevation.

[0257] During the downward return process of the first bracket 110, a driving force can be applied downward to the mounting structure or the flash. The first bracket 110 drives the linkage member 140 to move downward through the second limiting member 150. The second inclined surface 1611 of the sliding member 161 at the lower end of the linkage member 140 moves downward along the first inclined surface 241. Subject to the resistance of the first inclined surface 241, the downward force of the linkage member 140 is decomposed into two component forces in different directions. One lateral component force is offset by the compression of the third elastic member (which can be a shrapnel); the other is an upward component force, which is used to hinder the downward movement of the linkage member 140, causing the gear 120 to rotate, synchronously rotating the flash, and moving downward. As Figure 64 shown, until the first bracket 110 returns to the first position, the limiting surface 1911 of the limiting part 191 of the key 190 and the protrusion 111 on the first bracket 110 also resume the abutting state. Figure 64The direction of the arrow in the figure indicates the direction of the driving force. Without limitation, the driving force can be manual or electrically driven.

[0258] Figures 58 to 63 Exemplarily, a schematic structural diagram of the terminal 200 is shown when the first bracket 110 returns downward by 1 / 6 of the total stroke and the fitting 300 rotates 90°.

[0259] In the embodiment of the present disclosure, when the flash is fully popped up, at this time, the first limiting member 230 limits the linkage member 140, so that the whole linkage member 140 no longer moves upward; at the same time, under the action of the first elastic force of the first elastic member 130, the overall structure of the flash reaches a force balance upward, so that the whole remains stationary.

[0260] The cooperation of the sliding member 161, the third limiting member 163 and the guiding member 240 can form an automatic locking mechanism. When there is a small external force, or vibration shock, etc., even if the first elastic member 130 undergoes elastic deformation, it will not cause the overall flash to displace and oscillate downward; affecting performance and user experience.

[0261] The installation structure mechanism of the embodiment of the present disclosure is delicate and has a small volume. It can be driven without electricity, reducing power consumption. The opening function can be quickly and conveniently realized through a button; the installation structure can not only provide a protection function for the accessories of the mobile phone, but also add new functions to provide the application of front and rear conversion of the accessories.

[0262] The features disclosed in several product embodiments provided by the present disclosure can be arbitrarily combined without conflict to obtain new product embodiments.
