It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1 to 6, an electronic device disclosed in an embodiment of the present application includes a device housing 100 and a device auxiliary accessory 200. The apparatus housing 100 is provided with an inner cavity 100a and an opening 100b communicating with the inner cavity 100a, and the apparatus auxiliary fitting 200 is detachably provided to the apparatus housing 100. The equipment housing 100 is a base member that provides a mounting base for the equipment accessory 200.

The apparatus auxiliary accessory 200 includes a camera module 230, and the apparatus auxiliary accessory 200 is separated from the apparatus housing 100 in a case where the apparatus auxiliary accessory 200 is in the first state, and the apparatus auxiliary accessory 200 is assembled to the apparatus housing 100 in a case where the apparatus auxiliary accessory 200 is in the second state. In this state, the user can complete the assist operation through the device assist accessory 200.

When the auxiliary device 200 is in the second state and is located at the first position, the auxiliary device 200 is located in the cavity 100a, and the shooting direction of the camera module 230 is aligned with the direction of the opening 100b, and the opening 100b faces the length direction or the width direction of the electronic device. In this state, storage of the auxiliary equipment 200 can be achieved. Specifically, the auxiliary accessory 200 is accommodated in the inner cavity 100a, so that portability of the electronic device can be improved, and meanwhile, the auxiliary accessory 200 can be prevented from being pulled and hung with the outside, and the auxiliary accessory 200 can be prevented from being lost.

With the auxiliary equipment 200 in the second state and in the second position, the camera module 230 extends out of the equipment housing 100 at least partially through the opening 100 b. In this state, the image capturing module 230 in the apparatus auxiliary accessory 200 protrudes out of the apparatus housing 100, so that the size of the image capturing module 230 in the photographing direction is not limited by the thickness direction of the electronic apparatus. In addition, the length of the camera module 230 in the view direction is not limited by the length or the width dimension of the electronic device, so that the limitation of the thickness, the length and the width dimension of the electronic device on the type and the shooting performance of the camera module 230 can be avoided.

Further, the camera module 230 may include a zoom lens. In the case that the auxiliary accessory 200 is in the second state and is located in the first position, the zoom lens is adjusted to make the zoom lens in the short focal length state, so as to reduce the length of the camera module 230, and further reduce the space occupied by the auxiliary accessory 200 by the camera module 230. Under the condition that the auxiliary accessory 200 is in the second state and is located at the second position, the camera module 230 can realize focal length adjustment outside the device housing 100 according to shooting requirements, so that the zoom range of the camera module 230 is not limited by the length, width and thickness dimensions of the electronic device, and the camera module 230 with larger zoom ratio is further suitable for being installed. In this embodiment, when the auxiliary accessory 200 is required to be stored in the device housing 100, the length of the auxiliary accessory 200 is reduced by adjusting the focal length of the camera module 230, and after the camera module 230 extends out of the device housing 100, the focal length of the camera module 230 is adjusted, so that the device housing 100 can be prevented from providing a zoom space for the camera module 230, and the internal space of the device housing 100 occupied by the camera module 230 is reduced. Further, the camera module 230 may be configured as a tele camera.

Referring to fig. 6 to 12, the auxiliary equipment 200 may include a first section 210 and a second section 220, the second section 220 being movably connected to the first section 210, the camera module 230 being disposed on the second section 220, the camera module 230 being movable with the second section 220. With this structure, the position of the second section 220 can be adjusted to adjust the shooting direction of the camera module 230.

Referring to fig. 8 to 12, the second section 220 is rotatably connected to the first section 210, and when the auxiliary device 200 is in the second state and is in the second position, the first section 210 is at least partially located in the inner cavity 100a, the camera module 230 protrudes from the device housing 100 through the opening 100b along with the second section 220, and the second section 220 is switchable between a first angle and a second angle with respect to the first section 210. With the second section 220 rotated to the first angle, the second section 220 is coaxial with the first section 210. When the second section 220 is rotated to the second angle, the second section 220 intersects the first section 210, and the photographing direction of the photographing module 230 is consistent with the thickness direction of the electronic device. In particular, there are many ways to rotationally couple the first section 210 and the second section, such as by ball hinges, pivot hinges, memory metal connectors, and the like. The present application is not limited to the specific structure of the rotary connector 240.

Referring to fig. 8 to 13, the apparatus auxiliary fitting 200 may further include a rotational link 240 and a telescopic bracket 270, a first end of the telescopic bracket 270 being connected to the first section 210, a second end of the telescopic bracket 270 being connected to the first end of the rotational link 240, a second end of the rotational link 240 being connected to the second section 220, and the first section 210 being rotatably connected to the second section 220 through the rotational link 240 and the telescopic bracket 270. With the second segment 220 rotated to the first angle, the telescoping support 270 is in a contracted state. With the second segment 220 rotated to the second angle, the telescoping support 270 is in an extended state. The extension of the telescopic bracket 270 increases the gap between the first and second sections 210 and 220, thereby enabling flexibility in rotation between the first and second sections 210 and 220. The telescoping support 270 shortens not only the length of the equipment accessory 200, but also prevents the second section 220 from rotating with the first section 210. Specifically, the telescopic bracket 270 is shortened, and the distance between the end surface of the first section 210 and the end surface of the second section 220 is shortened, thereby preventing the second section 220 from rotating relative to the first section 210.

The telescopic bracket 270 is of various types, and specifically, the telescopic bracket 270 may be a voice coil motor, a hydraulic rod, a pneumatic rod, a screw mechanism, etc. driven by telescopic motion. The present application is not limited to the specific structure of the telescopic bracket 270.

The rotational connection 240 may be a ball hinge, a shaft hinge, a memory metal connection, or the like. The present application is not limited to the specific structure of the rotary connector 240.

There are many ways in which the second end of the swivel connection 240 can be connected to the second section 220. Specifically, the second end of the rotational connector 240 may be fixedly coupled or rotationally coupled to the second segment 220.

Referring to fig. 12, the rotational link 240 may include a first link 242 and a guide rail 243. The first end of the first connecting piece 242 is in rotating fit with the second end of the telescopic bracket 270, and the first connecting piece 242 can rotate around the joint of the telescopic bracket 270 and the first connecting piece 242. The guide rail 243 is fixedly disposed at one end of the second section 220 near the first section 210, the guiding direction of the guide rail 243 is perpendicular to the length direction of the second section 220, the second end of the first connecting member 242 is slidably engaged with one end of the second section 220 near the first section 210 through the guide rail 243, and the first connecting member 242 slides along the guide rail 243. The scheme can shorten the avoidance space between the first section 210 and the second section 220, and increase the bending resistance of the joint of the first section 210 and the second section 220 when the first section 210 and the second section 220 are coaxial. Referring to fig. 13, when it is desired that the second section 220 is deflected toward the first side of the telescopic bracket 270, the second section 220 may be pushed toward the direction away from the first side of the telescopic bracket 270, so that the end surface area of the second section 220 on the first side of the telescopic bracket 270 is reduced, and thus the avoidance space between the first section 210 and the second section 220 may be shortened. When the swivel connector 240 is wrapped with the flexible tubing 250, the connection between the first section 210 and the second section 220 is bent such that the flexible tubing 250 is stretched near the outside portion of the bend and the flexible tubing 250 is compressed near the inside portion of the bend. Sliding the second section 220 effectively reduces the amount of deformation of the flexible hose 250 inside the bend that is compressed, thereby reducing the resistance experienced by the second section 220.

Referring to fig. 12, the guide rail 243 may be provided with a guide groove 2431, the first link 242 is provided with a pulley 2421, and the pulley 2421 is positioned in the guide groove 2431. The pulley 2421 can convert sliding friction between the first link 242 and the guide rail 243 into rolling friction, and thus can greatly reduce resistance between the second end of the first link 242 and the guide rail 243. The guide groove 2431 can function as a guide on the one hand, and the end of the guide groove 2431 can also function as a limit to limit the sliding range of the second end of the first link 242 with respect to the guide rail 243 on the other hand.

Referring to fig. 9 and 10, the rotational coupling 240 includes a first partial gear 244 and a second partial gear 245, the first partial gear 244 being disposed at a second end of the telescopic bracket 270, and the second partial gear 245 being disposed at an end of the second section 220 adjacent to the first section 210. The first partial gear 244 is in driving engagement with the second partial gear 245, and the second partial gear 245 deflects the second section 220 relative to the first section 210. This arrangement can improve the stability of the deflection of the second section 220 relative to the first section 210 and improve the accuracy of the control of the angle of deflection of the second section 220 relative to the first section 210. Further, the first partial gear 244 is fixedly disposed at the second end of the telescopic bracket 270, the second partial gear 245 is in rotation fit with the second section 220, and the second partial gear 245 rotates around the first partial gear 244 and drives the second section 220 to rotate around the first partial gear 244.

The first partial gear 244 includes a first disk 2441 and a first arcuate rack 2442, the first arcuate rack 2442 being circumferentially disposed along a sidewall of the first disk 2441. The second partial gear 245 includes a second wheel 2451 and a second arcuate rack 2452, the second arcuate rack 2452 being circumferentially disposed along a sidewall of the second wheel 2451. With the second section 220 in the first position, the first end of the first arcuate rack 2442 is engaged with the first end of the second arcuate rack 2452. With the second section 220 in the second position, the second end of the first arcuate rack 2442 is engaged with the second end of the second arcuate rack 2452. The scheme utilizes the engagement of the end part of the first arc-shaped rack 2442 and the end part of the second arc-shaped rack 2452 to realize that the second section 220 blocks the relative rotation of the second section 220 relative to the first section 210, so that the positioning deflection of the second section 220 can be realized. Specifically, the length of the first and second arcuate racks 2442, 2452 may be set according to the angle of deflection of the second section 220 relative to the first section 210.

Referring to fig. 10, the rotary link 240 may further include a second link 241, a first end of the second link 241 being in rotary engagement with the telescopic bracket 270, and a second end of the second link 241 being connected to an end of the second segment 220 adjacent to the first segment 210. One of the purposes of the second connection 241 is to ensure the inter-axle spacing of the first partial gear 244 and the second partial gear 245, thereby preventing the first partial gear 244 and the second partial gear 245 from failing in mesh. The second link 241 rotates about the axis of the first partial gear 244 with respect to the telescopic bracket 270. The second connecting piece 241 may be fixedly connected to the second section 220 or may be in a rotational fit. The specific manner of connection of the second connecting member 241 to the second segment 220 is not limited by the present application.

Referring to fig. 6 and 7, the device accessory 200 may further include a flexible hose 250, the flexible hose 250 being sleeved over the swivel connector 240 and/or the telescoping bracket 270, and a first end of the flexible hose 250 being connected to the first section 210 and a second end of the flexible hose 250 being connected to the second section 220. One of the purposes of the flexible hose 250 is to prevent external dust from entering the junction of the first section 210 and the second section 220 and to improve the waterproof and dust-proof properties of the auxiliary fitting 200.

The first and second electrical connections 260 and 120 may be disposed at different positions of the device accessory 200 and the device housing 100, respectively, as desired. The specific positions of the first and second electrical connections 260 and 120 are not limited by the present application.

One of the first electrical connection portion 260 and the second electrical connection portion 120 may be a contact pad, and the other may be a metal spring. In the case that the auxiliary device 200 is in the second state and is located in the second position, the metal spring may elastically abut against the contact pad. Specifically, the first electrical connection portion 260 may be a contact pad, and the second electrical connection portion 120 may be a metal spring sheet, so as to improve the aesthetic property of the auxiliary accessory 200, and also prevent the first electrical connection portion 260 from being pulled from the outside.
