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

As shown in fig. 1 to 5, an embodiment of the present application discloses an electronic device, which includes a device housing 100, a lens 200, a magnetic attraction positioning mechanism 300, and a driving mechanism 400.

The device case 100 is an outer frame portion of the electronic device, has a certain accommodation space to accommodate an internal structure of the electronic device, and plays a role of protecting the internal structure of the electronic device. The lens 200 is a functional structure of the electronic apparatus such that the electronic apparatus has a function of photographing, and the electronic apparatus includes a camera including the lens 200. The magnetic attraction positioning mechanism 300 can assist the electronic device to perform the attraction positioning function of the respective components, and the driving mechanism 400 can drive the lens 200 to perform the zooming function in the embodiment of the present application to meet different user requirements.

The driving mechanism 400 is provided in the apparatus case 100, and the driving mechanism 400 is connected to the lens 200 so that the driving mechanism 400 can exert a driving action on the lens 200. The magnetic attraction positioning mechanism 300 includes a first structure 310 and a second structure 320, the first structure 310 is disposed on the lens 200, and the second structure 320 is disposed on the device housing 100, in which case, the first structure 310 and the second structure 320 cooperate to enable the lens 200 and the device housing 100 to generate a corresponding cooperating relationship.

The driving mechanism 400 is an electromagnetic driving mechanism, and when the driving mechanism 400 is powered on, the lens 200 operates, that is, the electromagnetically driven driving mechanism 400 can generate a certain driving force, and the driving force drives the lens 200 to move in the optical axis direction of the lens 200. Under the condition that the driving mechanism 400 is powered off, the lens 200 is not limited by the driving mechanism 400, and at this time, the lens 200 is fixedly connected with the device housing 100 through the magnetic attraction between the first structural member 310 and the second structural member 320, so that abnormal noise caused by the movement of the lens 200 in the device housing 100 or the influence on the service life of the electronic device can be avoided.

The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, and the magnetic attraction positioning mechanism 300 including the first structural member 310 and the second structural member 320 is additionally arranged in the electronic device, and the first structural member 310 is arranged on the lens 200, and the second structural member 320 is arranged on the device housing 100, so that the energized driving mechanism 400 can drive the lens 200, and the lens 200 moves in the optical axis direction thereof to realize the zoom camera effect of the lens 200.

Under the condition that the driving mechanism 400 is powered off, the magnetic adsorption positioning effect between the first structural member 310 and the second structural member 320 is displayed, the lens 200 is adsorbed on the device shell 100 through the magnetic adsorption between the first structural member 310 and the second structural member 320, so that the lens 200 is fixed on the device shell 100 under the condition that the driving mechanism 400 is powered off, and therefore the lens 200 can be prevented from colliding with components inside the electronic device due to the fact that the limiting acting force of the driving mechanism 400 is lost, and further sound is generated. The electronic device disclosed in the embodiment of the application can undoubtedly solve the problems that the sound of collision can occur inside the electronic device and the service life of the electronic device is influenced by the collision inside the electronic device in the background art.

In the electronic device disclosed in the embodiment of the present application, the first structural member 310 may be a first permanent magnet, the second structural member 320 may be a second permanent magnet, and polarities of the first structural member 310 and the second structural member 320 are opposite, in this case, the first structural member 310 and the second structural member 320 have an attractive effect, and the permanent magnet has magnetism without being energized, so that a complicated circuit structure can be avoided from being disposed in the electronic device, an internal structure of the electronic device can be simplified, and production and manufacturing of the electronic device are facilitated. It should be noted that the types of the permanent magnets are various, and the first permanent magnet and the second permanent magnet may be alloy permanent magnets or ferrite permanent magnets.

In other aspects, the first structural member 310 may be a first metal piece, and the second structural member 320 may be a second permanent magnet; alternatively, the first structural member 310 may be a first permanent magnet, and the second structural member 320 may be a second metal member, and various schemes can achieve the adsorption positioning effect between the first structural member 310 and the second structural member 320.

In the electronic device disclosed in the embodiment of the present application, the first structural member 310 may be a first permanent magnet, the driving mechanism 400 may include a first electromagnetic coil 410 and a third permanent magnet 420, the first electromagnetic coil 410 is disposed on the device housing 100, and the third permanent magnet 420 is disposed on the lens 200. In this case, for the same reason, since the first electromagnetic coil 410 is disposed on the device housing 100 and the third permanent magnet 420 is disposed on the lens 200, the device housing 100 and the lens 200 can have a corresponding fitting relationship in the process of the first electromagnetic coil 410 and the third permanent magnet 420 cooperating with each other. Of course, the two parts magnetically attracted to each other above may also be interchanged in position.

Specifically, when the driving mechanism 400 is powered on, the first electromagnetic coil 410 is powered on, and at this time, a magnetic force that is mutually adsorbed exists between the first electromagnetic coil 410 and the third permanent magnet 420, so that the cooperation between the first electromagnetic coil 410 and the third permanent magnet 420 is converted into driving movement of the driving mechanism 400 on the lens 200, and thus a function of zooming and shooting of the lens 200 in the electronic device is realized. In a more specific scheme, the third permanent magnet 420 may be a first permanent magnet, that is, the first permanent magnet may serve as the third permanent magnet 420, so that multiplexing of the first permanent magnet is realized in the electronic device, and thus materials can be saved, cost can be reduced, and the internal structure of the electronic device can also be simplified.

In a further embodiment, the second structural member 320 may be a second electromagnetic coil, and the electronic device may further include a control module, wherein the control module is connected to both the second electromagnetic coil and the first electromagnetic coil 410. The control module controls the first electromagnetic coil 410 to be powered on and the second electromagnetic coil to be powered off simultaneously, so that when the lens 200 needs to move to work, the magnetic adsorption positioning mechanism 300 is disconnected from adsorbing and positioning the lens 200, thereby being beneficial to exerting the driving effect of the driving mechanism 400 on the lens 200, preventing the driving of the driving mechanism 400 on the lens 200 from being blocked by the magnetic adsorption acting force between the first structural member 310 and the second structural member 320, so that the driving mechanism 400 can drive the lens 200 to move when having smaller driving force, further enabling the power of the driving mechanism 400 to be smaller, further saving the energy consumption of the electronic device, and simultaneously improving the electrification performance of the electronic device.

In other embodiments, both the first electromagnetic coil 410 and the second electromagnetic coil may be charged, and when the lens 200 needs to move, the control module may control both the first electromagnetic coil 410 and the second electromagnetic coil to be charged, only that the driving mechanism 400 needs to generate a larger acting force capable of overcoming the acting force other than the acting force of the magnetic attraction positioning mechanism 300 to drive the lens 200 to move at this time, compared with the above scheme, the scheme may consume a relatively large amount of electric energy, but the control mode of the control module is relatively simple, and the embodiment of the present application does not specifically limit the structural function of the control module.

In an optional scheme, in the electronic device disclosed in the embodiment of the present application, the electronic device may further include a light sensing chip 500, and the light sensing chip 500 may convert the received optical signal into a digital signal. The first structural member 310 is disposed on a first end surface of the lens 200 facing the photosensitive chip 500, and the second structural member 320 is disposed on a first inner sidewall of the apparatus case 100 adjacent to the photosensitive chip 500. In this case, the driving mechanism 400 is in the power-off state, and the suction positioning function between the first structural member 310 and the second structural member 320 is fully exerted, that is, the lens 200 is suction-fixed on the device housing 100, and the lens 200 is immovable due to being fixed and is closer to the photo sensor chip 500, so that the lens 200 is in the short-focus image capturing state in the electronic device.

In another alternative, in the electronic device disclosed in the embodiment of the present application, the electronic device may further include a photosensitive chip 500, the first structural member 310 is disposed on a second end surface of the lens 200 facing away from the photosensitive chip 500, and the second structural member 320 is disposed on a second inner side wall of the device housing 100 away from the photosensitive chip 500. In this case, the suction force between the first structural member 310 and the second structural member 320 causes the lens 200 to be positioned away from the photosensitive chip 500, thereby causing the lens 200 to be in a telephoto imaging state in the electronic apparatus.

In the electronic device disclosed in the embodiment of the present application, the number of the first structural members 310 may be at least two, and the first structural members 310 are symmetrically disposed on two sides of the optical axis of the lens 200, and the number of the second structural members 320 may also be at least two, so that the absorption force between the first structural members 310 and the second structural members 320 may be matched in a one-to-one correspondence manner. In the power-off state of the driving mechanism 400, the absorption positioning actions between the at least two first structural members 310 and the at least two second structural members 320 can be evenly distributed on two sides of the optical axis of the lens 200, so that the lens 200 is in a more balanced position in the device housing 100, and the lens 200 can be better prevented from colliding inside the electronic device.

In the electronic device disclosed in the embodiment of the present application, the device housing 100 may be provided with a limiting protrusion 110, the lens 200 may be provided with a limiting groove 210, and the limiting protrusion 110 and the limiting groove 210 may be in limiting fit in the moving direction of the lens 200. In the case where the driving mechanism 400 is powered off and the lens 200 is fixedly connected to the device housing 100 by magnetic attraction between the first structural member 310 and the second structural member 320, the limiting protrusion 110 is in limiting contact with the limiting groove 210 at the first sidewall far from the second structural member 320, and in this case, the limiting contact between the limiting protrusion 110 and the limiting groove 210 can prevent excessive squeezing caused by excessive approach between the lens 200 and the device housing 100, thereby ensuring safety of the lens 200 when functioning as a short-focus camera.

In a further embodiment, the limiting groove 210 may have a second side wall adjacent to the second structure 320, and the limiting protrusion 110 is in limiting contact with the second side wall in a direction in which the first structure 310 is away from the second structure 320, in which case, the limiting contact between the limiting protrusion 110 and the second side wall can avoid a problem that the internal structure of the electronic device is damaged due to excessive distance between the lens 200 and the device housing 100.

In summary, the arrangement and the cooperation of the limiting protrusion 110 and the limiting groove 210 can limit the distance between the lens 200 and the device housing 100 within a proper range, so as to avoid the problem of failure caused by excessive movement between the lens 200 and the device housing 100, and further improve the use safety and the service life of the electronic device.

The device housing 100 may be formed with a light inlet hole. The photosensitive chip 500, the lens 200, and the reflective member 600 are sequentially disposed in an optical axis direction, which intersects with a through direction of the light inlet hole, and the light inlet hole extends in a thickness direction of the electronic device. In a general case, an electronic device includes a display screen, and a direction perpendicular to the display screen may be considered as a thickness direction of the electronic device. In this case, the external light may enter the reflection member 600 through the light inlet hole to reflect the light, in a specific embodiment, the reflection member 600 may be a prism or a plane mirror, the light processed by the reflection member 600 enters the lens 200, and finally the light enters the photosensitive chip 500, thereby achieving the photosensitive of the photosensitive chip 500.

The setting of reflection piece 600 makes during light can get into electronic equipment from a plurality of directions, and sensitization chip 500, camera lens 200 and reflection piece 600 set gradually in the optical axis direction to crossing with electronic equipment's thickness direction, and then can make electronic equipment form periscopic camera structure, and periscopic camera structure can make full use of electronic equipment's the space of length and width direction form the structure of shooing of longer burnt, also is favorable to electronic equipment's frivolousization development simultaneously.
