When using the camera device, the user first inputs a trigger operation to turn on the camera assembly 131 to the mobile terminal 100, and the mobile terminal 100 can disconnect the power supply to the first telescopic component 1342 according to the trigger operation, and the first telescopic component 1342 stretches after power off , The first elastic component 1341 stretches accordingly, pushing the camera assembly 131 to extend out of the receiving cavity 101 from the opening 121.

After the use is over, the user can again input a trigger operation to turn off the camera assembly 131 into the mobile terminal 100, and the mobile terminal 100 can convert the trigger operation into an electrical signal and send it to the first retractable part 1342, which shrinks after being powered on , So that the first supporting member 132 is close to the first bottom plate 133, and the first elastic member 1341 is compressed, so that the camera assembly 131 enters the receiving cavity 101.

However, in the above embodiment, in order to maintain the state of the camera assembly 131 in the accommodating cavity 101, the mobile terminal needs to supply power to the first telescopic member 1342 for a long time, which consumes a lot of power, and the first telescopic member 1342 is energized Afterwards, it will generate heat, which may increase the internal temperature of the mobile terminal and affect the performance of the mobile terminal.

To this end, an embodiment of the present application also provides an imaging device. FIG. 8 is a first state diagram of another camera device provided by an embodiment of the application. FIG. 9 is a second state diagram of another camera device provided by an embodiment of the application. FIG. 10 is a third state diagram of another camera device provided by an embodiment of the application. FIG. 11 is a fourth state diagram of another camera device provided by an embodiment of the application. Referring to FIGS. 8, 9, 10, and 11, the camera assembly 131, the first supporting member 132, the first elastic member 1341, and the first telescopic member 1342 in the camera device are all the same as those in the foregoing embodiment. I will not repeat them here. On this basis, the camera device may further include: a buckle 136 disposed in the receiving cavity 101, a second supporting member 137 for supporting the buckle 136, and a second supporting member 137 opposite to the second supporting member 137 The second bottom plate 138.

The embodiment of the application does not limit the position and specific structure of the buckle 136. The buckle 136 can be arranged on any side of the first supporting member 132. The buckle 136 may be, for example, a strip-shaped plate, the buckle 136 and the first support member 132 respectively include a first surface and a second surface opposite to each other, and the buckle 136 and the first support member 132 are engaged with each other. When connected, the second surface of the buckle 136 contacts the first surface of the first supporting member 132.

In order to facilitate the control of the ejection and retraction of the buckle 136, a second elastic member 1391 is provided between the second support member 137 and the second bottom plate 138, and the telescopic member further includes: The second telescopic part 1392 between the second bottom plates. When the second telescopic member is in the first state, the first support member 132 receives a downward force F1, so that the first elastic member 1341 is in a compressed state. When the first state is changed to the second state, the F1 becomes smaller or disappears, so that the first elastic member 1341 returns to a free state, so that the first supporting member 132 drives the camera assembly 131 to move away from the first The direction of the bottom plate 133 moves. The first state of the second telescopic component 1392 is an extended state, and the second state of the second telescopic component 1392 is a contracted state.

For the specific structure and connection mode of the second telescopic component 1392 in the embodiment of the present application, reference may be made to the first telescopic component 1342 in the above-mentioned embodiment, which will not be repeated here.

The first surface of the buckle 136 includes a first guide surface 1361, and the second surface of the first support member 132 includes a second guide surface 1322. The first guide surface 1361 and the second guide surface 1322 are parallel, such that It is advantageous for the first support member 132 to be clamped into the housing 12. When the first elastic member 1341 contracts, the second guide surface 1322 of the first support member 132 is close to the first guide surface 1361 of the buckle 136, Push the buckle 136 away from the clamping position, so that the camera assembly 131 enters the receiving cavity 101, and then the buckle 136 can be ejected under the action of the second elastic member 1392 to limit the camera assembly 131 in the receiving cavity 101 .

The included angle between the first guide surface of the buckle 136 and the second guide surface 1322 of the first support member 132 and the horizontal plane is, for example, 30° to 75°, which facilitates the first support member 132 to be clamped into the housing In the body 12, the included angle between the second surface of the buckle 136 and the first surface of the first supporting member 132 and the horizontal plane is, for example, 0°, which enables the first supporting member 132 to be positioned in the housing 12 The high stability in the medium makes it difficult for the first supporting member 132 to come out.

Therefore, when the camera assembly 131 returns to the receiving cavity 101, the buckle 136 pops out to confine the camera assembly 131 in the receiving cavity 101. There is no need to supply power to the first telescopic member 1342 for a long time, which can save movement. The terminal uses electricity and at the same time prevents the first telescopic component 1342 from heating and affecting the performance of the mobile terminal.

In order to improve the stability of the second support member 137, the second bottom plate 138 is further provided with a guide sleeve 130, the guide sleeve 130 is sleeved on the outside of the second support member 137, and the second elastic member 1391 During expansion and contraction, the second support member 137 can slide along the inner side wall of the guide sleeve 130 toward or away from the second bottom plate 138. Thus, the stability of the second support member 137 can be improved.

An end of the guide sleeve 130 away from the second bottom plate 138 is further provided with a limit plate 1301, and the limit plate 1301 is used to limit the second support member 137 in the guide sleeve 130. The limiting plate is provided with an opening allowing the buckle 136 to pass through. When the second supporting member 137 slides along the inner side wall of the guide sleeve 130 toward or away from the second bottom plate 138, the buckle 136 movably passes through the guide sleeve 130 and can be passed through or retracted from the guide sleeve 130. The guide sleeve can limit the movement of the buckle 136, so that the buckle 136 moves in a straight line in the guide sleeve 130, so that The movement of the buckle 136 is smoother and more stable.

Wherein, the position state of the buckle 136 includes a clamping process, a disconnection process, a clamping position or a disconnection position. The "clamping process" here refers to the process in which the buckle 136 extends from the guide sleeve 130 to the outside of the guide sleeve 130 and is clamped with the first supporting member 132; the "disconnecting process" here refers to the detachment of the buckle 136 The clamping with the first supporting member 132 is the process of retracting the guide sleeve 130 from the outside of the guide sleeve 130; the "clamping position" here refers to the position where the camera assembly 131 is clamped with the first supporting member 132; here The “disconnected position” means that the camera assembly 131 is located in the guide sleeve 130 of the mobile terminal 100.

As shown in FIG. 8, when the buckle is engaged with the first supporting member, the second telescopic member 1392 and the second elastic member 1391 are in a stretched state, and the buckle 136 provides The force F1 of the supporting member 132 toward the first bottom plate 133 causes the first elastic member 1341 to be in a compressed state. At this time, the camera assembly 131 is in the retracted position, and the buckle 136 is in the clamping position.

As shown in FIG. 9, when the second elastic member 1392 is changed from the extended state to the contracted state, the second elastic member 1391 shrinks accordingly, and the second supporting member 137 drives the buckle 136 moves in a direction close to the second bottom plate 138, the first support member 132 is disconnected from the buckle 136, the F1 becomes smaller or disappears, and the first elastic member 1341 returns to a free state , So that the first supporting member 132 drives the camera assembly 131 to move in a direction away from the first bottom plate 133. At this time, the buckle 136 is in the disconnected position, and the camera assembly 131 is in the stretching process.

As shown in FIG. 10, the second elastic member 1392 is changed from the contracted state to the extended state again, the second elastic member 1391 is also restored to a free state, and the buckle 136 pops out. At this time, the camera assembly 131 is in the extended position, and the buckle 136 is in the clamping position.

As shown in Figure 11, the second elastic member 1391 and the first elastic member 1341 are both in a free state, and the first supporting member 132 can drive the first support member 132 after receiving a force F2 toward the first bottom plate 133. The camera assembly 131 moves in a direction close to the first bottom plate 133, so that the buckle 136 is engaged with the first supporting member 132, so that the first elastic member 1341 returns to the compressed state. At this time, the camera assembly 131 is in the shrinking process, and the buckle 136 is in the state of the clamping position.

Wherein, the F2 is, for example, the force applied by the first telescopic component 1342 to the first supporting member 132 when the first telescopic component 1342 is changed from the extended state to the contracted state.

When the user uses the camera device, he first inputs a trigger operation to turn on the camera assembly 131 into the mobile terminal. The mobile terminal can convert the trigger operation into an electrical signal and send it to the second telescopic member 1392. The second telescopic member 1392 is energized and contracted, so that The second supporting member 137 is close to the second bottom plate 138 and compresses the second elastic member 1391, so that the buckle 136 is disconnected from the first supporting member 132 and enters the guide sleeve 130 Inside. After the first supporting member 132 is disconnected from the buckle 136, the first elastic member 1341 is extended accordingly, pushing the camera assembly 131 to extend out of the receiving cavity 101 from the opening 121. When the user uses the camera device, the power supply to the second telescopic component 1392 can be disconnected, so that the buckle 136 extends from the inside of the guide sleeve 130 to the outside of the guide sleeve 130 and reaches the clamping position.
