Electronic device

Technical Field

The application belongs to the technical field of communication equipment, and particularly relates to electronic equipment.

Background

With the advancement of technology, electronic devices (e.g., mobile phones, tablet computers) have been developed. As a powerful tool, the electronic equipment brings great convenience to the life and work of users.

In the related art, the electronic device is usually provided with a camera module, a key module, a receiver and other functional components, so as to realize functions of shooting, controlling, talking and the like of the electronic device.

In the process of implementing the invention, the inventor finds that in the related art, functional components such as the camera module, the key module, the telephone receiver and the like are exposed out of the shell of the electronic device, and because the functional components are exposed, the exposed functional components are easy to damage when the electronic device falls off.

Disclosure of Invention

The embodiment of the application aims to provide electronic equipment, and the problem that exposed functional components are easy to damage in the falling process of the electronic equipment can be solved.

In order to solve the technical problem, the present application is implemented as follows:

an embodiment of the present application provides an electronic device, including:

the shell is provided with an inner cavity and a through hole communicated with the inner cavity;

the functional assembly is positioned in the inner cavity and comprises a driving mechanism, a functional part, a first bracket, a second bracket, a first limiting part and a first elastic part;

the driving mechanism is connected with the first support, the first support is elastically connected with the second support through the first elastic piece, and the functional part is connected with the second support;

the driving mechanism drives the functional part to switch between an extended state and a retracted state through the first bracket, the first elastic piece and the second bracket, wherein when the functional part is in the extended state, at least part of the functional part extends out of the shell through the through hole, and when the functional part is in the retracted state, the functional part retracts into the shell;

the first limiting part is movably arranged in the inner cavity, and under the condition that the functional part is in an extending state, the first limiting part is in limiting fit with the second support to limit the second support to move along a retracting direction; when the functional portion is in the retracted state, the second bracket is separated from the first stopper.

In the embodiment of the present application, the drive mechanism switches the drive function portion between the extended state and the retracted state through the first bracket, the first elastic member, and the second bracket. Under the condition that the functional part is in the extending state, at least part of the functional part extends out of the shell through a through hole formed in the shell; with the functional portion in the retracted state, the functional portion is retracted within the housing. In this aspect, when the functional component operates, the functional portion is in the extended state. When the functional assembly is not operating, the functional portion is in a retracted state. Because the functional components are hidden in the shell under the condition of non-working, the functional components are not easy to expose, so that the functional components are not directly contacted with the ground or external objects in the falling process of the electronic equipment, and the probability of damage of the functional components can be reduced.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

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.

Referring to fig. 1 to 13, an embodiment of the present application discloses an electronic device, which includes a housing 100 and a functional assembly 200.

The housing 100 provides a mounting base for the component parts of the electronic device. In the embodiment of the present application, the housing 100 defines an inner cavity 110 and a through hole communicating with the inner cavity 110.

Specifically, the housing 100 has a frame, and in a general case, the frame is provided with a through hole for the functional assembly 200 to pass through and enter the housing 100. The components of the housing 100 of different configurations that form the bezel are different. For example, the case 100 may include a front case, a rear cover, and a middle frame disposed therebetween. The rim may be formed on the middle frame. In this case, the frame serves as a part of the middle frame. For another example, the housing 100 may include a front cover and a rear cover, and the frame may be formed on the rear cover or the front cover. Of course, the functional assembly 200 can enter and exit the housing 100 through other passages, and is not limited to the through hole formed on the frame.

The functional component 200 is located in the inner cavity 110, and the functional component 200 includes a driving mechanism 210, a functional portion 220, a first bracket 230, a second bracket 240, a first limiting member 250, and a first elastic member 261. The driving mechanism 210 is connected to the first bracket 230, the first bracket 230 is elastically connected to the second bracket 240 by a first elastic member 261, and the functional unit 220 is connected to the second bracket 240. The driving mechanism 210 switches the driving function part 220 between the extended state and the retracted state through the first bracket 230, the first elastic member 261, and the second bracket 240.

Wherein, in case the function part 220 is in the extended state, at least a part of the function part 220 is extended out of the housing 100 through the through hole, and in case the function part 220 is in the retracted state, the function part 220 is retracted into the housing 100.

The first limiting member 250 is movably disposed in the inner cavity 110, and when the functional portion 220 is in the extended state, the first limiting member 250 is in limiting engagement with the second support 240 to limit the second support 240 to move along the retraction direction. At this time, when the functional portion 220 is in the extended state, the first stopper 250 can prevent the second bracket 240 from retracting, so as to maintain the second bracket 240 at the position where the functional portion 220 is in the extended state, so that the functional portion 220 can be maintained in the extended state during normal operation, and prevent the functional portion 220 from retracting and being difficult to operate normally.

When the functional portion 220 is in the retracted state, the second bracket 240 is separated from the first stopper 250. At this time, when the functional portion 220 retracts into the housing 100, the second bracket 240 is separated from the first limiting member 250, so that the limiting of the second bracket 240 is released, and the second bracket 240 can move along the retracting direction of the functional portion 220, thereby driving the functional portion 220 to retract into the housing 100. It should be noted that the second bracket 240 and the first limiting member 250 are already separated during the process of retracting the functional portion 220 into the housing 100, but the functional portion 220 is not separated until it is completely retracted into the housing 100.

In a specific working process, when the functional assembly 200 works, the functional portion 220 is switched from the retracted state to the extended state, at this time, the first limiting member 250 is separated from the second bracket 240, and the driving mechanism 210 drives at least a portion of the functional portion 220 to extend out of the housing 100 through the through hole via the first bracket 230, the first elastic member 261, and the second bracket 240. When at least a portion of the functional portion 220 extends out of the housing 100, the first limiting member 250 is moved, so that the first limiting member 250 is in limiting engagement with the second bracket 240 to limit the movement of the second bracket 240 along the retraction direction. When the functional assembly 200 does not work, the functional portion 220 is switched from the extended state to the retracted state, and at this time, the first limiting member 250 is moved to separate the first limiting member 250 from the second bracket 240, so that the second bracket 240 is released from limiting, so that the second bracket 240 can move along the retraction direction of the functional portion 220, and the functional portion 220 is retracted into the housing 100.

In the embodiment disclosed in the present application, when the functional assembly 200 operates, the functional portion 220 is in an extended state. When the functional assembly 200 is not operating, the functional portion 220 is in a retracted state. Since the functional component 200 is hidden in the housing 100 when the electronic device is not in operation, the functional component 200 is not easily exposed, so that the functional component does not directly contact with the ground or an external object when the electronic device is dropped, the probability of damage can be reduced, and the safety of the electronic device is improved.

In addition, the functional assembly 200 is not easily exposed, so that the area of the functional assembly 200 occupying the appearance surface of the housing is small, the fracture feeling is weak, and the appearance performance of the electronic device is good.

In addition, the first support 230 and the second support 240 are elastically connected through the first elastic member 261, and compared to the rigid connection of the first support 230 and the second support 240, during the process of extending or retracting the functional part 220, the functional part 220 may rub against the inner surface of the through hole, which easily causes the functional part 220 to be jammed in the through hole and is difficult to extend or retract into the housing 100. The first bracket 230 and the second bracket 240 are elastically connected through the first elastic member 261, at this time, when the functional part 220 is jammed by the housing 100, the functional part 220 transmits the acting force to the second bracket 240, and because the first bracket 230 and the second bracket 240 are elastically connected, the second bracket 240 can slightly swing to adjust the angle of the second bracket 240 relative to the axis of the through hole, and when the position where the functional part 220 does not interfere with the housing 100 is adjusted, the functional part 220 can smoothly enter and exit the housing 100.

In addition, the first elastic member 261 may also serve as a buffer for the second bracket 240, so as to prevent the second bracket 240 and the functional portion 220 from being damaged due to rigid collision with other components of the electronic device, thereby improving the reliability of the functional assembly 200.

In the embodiment disclosed in the present application, when the functional portion 220 is in the extended state, the first limiting member 250 can prevent the second bracket 240 from retracting, so as to maintain the second bracket 240 at the position of the extended state of the functional portion 220, so that the functional portion 220 can be maintained in the extended state during normal operation, and prevent the functional portion 220 from retracting, so as to improve the reliability of the electronic device.

The functional component 200 in the above embodiments may be at least one of a camera module, a key module, and a receiver module, and thus the functional portion 220 may be a corresponding camera, a key, and a receiver. Of course, the functional assembly 200 may also be configured in other functional configurations and is not limited herein.

Alternatively, the driving mechanism 210 may be a driving motor, an electromagnetic driving mechanism, a shape memory alloy, or other power structures, which is not limited herein.

In an alternative embodiment, as shown in fig. 1, the driving structure may include a driving motor, and an end of a driving shaft of the driving motor is engaged with the first bracket 230.

Alternatively, in another alternative embodiment, as shown in fig. 2, the driving mechanism 210 may include an electromagnetic assembly and a magnetic member, the electromagnetic assembly may be fixed to the housing 100, the magnetic member may be fixed to the first support 230, and the electromagnetic assembly drives the first support 230 to move through the magnetic member when the electromagnetic assembly is powered on. There are various ways of driving the magnetic member by the electromagnetic assembly, for example, the magnetic member is an electromagnet, and the magnetism of the magnetic member and the electromagnetic assembly is changed by changing the current direction of the magnetic member and the electromagnetic assembly, so as to switch the function portion 220 between the extended state and the retracted state.

For another example, the magnetic member is a permanent magnet, and the electromagnetic assembly includes a first electromagnet and a second electromagnet, when the first electromagnet is powered on, the first electromagnet drives the first bracket 230 to move toward the extending direction of the functional portion 220, that is, the first electromagnet and the magnetic member cooperate to realize the switching of the functional portion 220 from the retracted state to the extended state. When the second electromagnet is energized, the second electromagnet drives the first bracket 230 to move toward the retraction direction of the functional portion 220, that is, the second electromagnet cooperates with the magnetic member to switch the function from the extended state to the retracted state. In this embodiment, a permanent magnet is required to be fixed on the first bracket 230, and in another alternative, the first bracket 230 may be made of a permanent magnet.

Of course, the driving mechanism 210 is not limited to the above-mentioned structures, and may also be other structures, which are not limited herein.

In the above embodiment, a driving motor for driving the first limiting member 250 may be disposed in the electronic device, and certainly, a circuit structure configured with the driving motor needs to be disposed in the electronic device, so that the electronic device has a complex structure and a large layout difficulty. In addition, the first limiting member 250 is driven by a driving motor, which increases the power consumption of the electronic device.

Based on this, in an alternative embodiment, the functional assembly 200 may further include a second elastic member 262, the housing 100 and the first limiting member 250 may be elastically connected through the second elastic member 262, and the first limiting member 250 abuts against the first bracket 230.

In a specific operation process, when the driving mechanism 210 drives the first bracket 230 to move along the retraction direction of the functional portion 220, the first bracket 230 may drive the first limiting member 250 to move along a side away from the second bracket 240, and the first limiting member 250 is separated from the second bracket 240. When the first bracket 230 moves along the retraction direction of the functional portion 220, the first bracket 230 applies an acting force to the first limiting member 250, the first limiting member 250 compresses the second elastic member 262, so that the first limiting member 250 is far away from the second bracket 240, and finally the first limiting member 250 is separated from the second bracket 240, at this time, the limiting of the second bracket 240 is released, so that the second bracket 240 drives the functional portion 220 to retract into the housing 100.

When the driving mechanism 210 drives the first bracket 230 to move along the extending direction of the functional portion 220, the second elastic member 262 drives the first limiting member 250 to move along a side close to the second bracket 240, and the first limiting member 250 is limited and matched with the second bracket 240. When the first bracket 230 moves along the extending direction of the functional portion 220, at this time, the first bracket 230 has no force on the first limiting member 250, and the compressed second elastic member 262 gradually recovers elastic deformation in the moving process of the first bracket 230, so as to drive the first limiting member 250 to move toward the side close to the second bracket 240, and finally, the first limiting member 250 is in limiting fit with the second bracket 240.

In this embodiment, the first support 230 and the second elastic member 262 drive the first limiting member 250 to move, so that the electronic device has a simple structure and a small layout difficulty. In addition, the first limiting member 250 is driven by the first bracket 230 and the second elastic member 262, so that the electric energy of the electronic device is not consumed, and the electronic device is more energy-saving.

A specific structure of the first limiting member 250 is disclosed herein, and of course, other structures are also possible, which are not limited herein, and specifically, the first limiting member 250 may include a limiting protrusion 251, a connecting portion 252 and a sliding protrusion 253, and the limiting protrusion 251 and the sliding protrusion 253 may be located at two ends of the connecting portion 252 and disposed on the same side of the connecting portion 252. The second elastic member 262 and the limiting protrusion 251 may be located on opposite sides of the connecting portion 252. The stopper protrusion 251, the connection part 252, and the sliding protrusion 253 may form a sliding space 254.

A side of the sliding protrusion 253 facing the stopper protrusion 251 may be provided with a first slope inclined in a direction away from the through hole. A first protrusion 231 may extend from one side of the first bracket 230 facing the first limiting member 250.

The first protrusion 231 can extend into the sliding space 254, and the first inclined surface is slidably engaged with the first protrusion 231.

With the functional part 220 in the extended state, the second bracket 240 is in limit-fitting engagement with the limit projection 251 in the retracting direction of the functional part 220. In the case where the function part 220 is in the retracted state, the function part 220 is separated from the stopper projection 251.

In this embodiment, the sliding protrusion 253 is engaged with the first bracket 230, so as to realize the movement of the first limiting member 250. The limiting protrusion 251 is used for limiting and matching with the second bracket 240, and at this time, the matching parts of the first bracket 230 and the second bracket 240 with the first limiting member 250 are different, so that the first bracket 230 and the second bracket 240 are not easy to interfere with each other, thereby further improving the safety of the electronic device.

In addition, the limiting protrusion 251, the connecting portion 252 and the sliding protrusion 253 may form a sliding space 254, the first protrusion 231 may extend into the sliding space 254, and during the moving process of the first bracket 230, the first protrusion 231 is in the sliding space 254, so that the first protrusion 231 is hidden in the sliding space 254, and further, the first protrusion 231 is not easily scratched with other components of the electronic device.

Further, the height of the stopper projection 251 is smaller than the height of the sliding projection 253. The height of the stopper protrusion 251 refers to a distance that the stopper protrusion 251 extends from one side of the connection part 252 toward the second bracket 240, and the height of the sliding protrusion 253 refers to a distance that the sliding protrusion 253 extends from one side of the connection part 252 toward the second bracket 240. At this time, the height of the sliding protrusion 253 is small, so that it is ensured that the sliding protrusion 253 does not interfere with the second bracket 240 after the limiting protrusion 251 is separated from the second bracket 240, thereby ensuring that the functional part 220 can be smoothly retracted into the housing 100, and further improving the reliability of the electronic device.

In another alternative embodiment, a matching protrusion 241 may extend from a side of the second bracket 240 facing the first limiting member 250. In the case where the functional part 220 is in the extended state, the fitting projection 241 may overlap the stopper projection 251. With the functional part 220 in the retracted state, the fitting projection 241 may be separated from the stopper projection 251. In this embodiment, the second frame 240 extends toward one side of the first limiting member 250 to form a fitting protrusion 241 that fits with the limiting protrusion 251 in a limiting manner, and the size of the other portion of the second frame 240 can be designed to be smaller, so that the space occupied by the second frame 240 in the housing 100 is reduced. In addition, the fitting protrusion 241 may be overlapped on the limiting protrusion 251, so that the fitting protrusion 241 is not easily separated from the limiting protrusion 251, and the reliability of the limiting fit between the second bracket 240 and the first limiting member 250 is ensured.

In the above embodiment, when the functional assembly 200 is in the working state, the functional portion 220 may be impacted by a large external force, and the first position-limiting member 250 limits the second bracket 240, so that the functional portion 220 is difficult to retract into the housing 100, and the functional portion 220 is easily damaged.

Based on this, in another alternative embodiment, the functional part 220 may be moved in the axial direction of the through hole with respect to the second bracket 240. When the functional portion 220 moves toward the inner cavity 110, the functional portion 220 may drive the first position-limiting member 250 to separate from the second bracket 240.

In a specific working process, when the functional assembly 200 is in a working state, the functional portion 220 moves toward the inner cavity 110 under the condition that the functional portion 220 is subjected to a large external force, first, the functional portion 220 contacts with the first limiting member 250, and in the process that the functional portion 220 moves toward the inner cavity 110, the first limiting member 250 is driven to move toward a side away from the second bracket 240, so that the second bracket 240 is separated from the first limiting member 250, at this time, since the second bracket 240 is separated from the first limiting member 250, the functional portion 220 drives the second bracket 240 to move toward the inner cavity 110, and the second bracket 240 compresses the first elastic member 261, so that the functional portion 220 can retract into the inner cavity 110. When the external force applied to the functional part 220 is removed, the first elastic member 261 pushes the second bracket 240 to move toward the extending direction of the functional part 220, so that the functional part 220 returns to the extending state, and the second elastic member 262 drives the first limiting member 250 to move to the position where it is limited and matched with the second bracket 240 again.

In this scheme, when the functional portion 220 is impacted by a large external force, the first limiting member 250 can be pushed to move, so as to remove the limitation between the first limiting member 250 and the second bracket 240, thereby playing a role in buffering the functional portion 220, preventing the functional portion 220 from being damaged due to an overlarge stress, and further improving the safety of the electronic device.

In another alternative embodiment, the functional assembly 200 may further include a third elastic member 263, and the functional portion 220 is elastically connected to the second bracket 240 through the third elastic member 263. In this embodiment, during the process of moving the functional part 220 inward, the functional part 220 is prevented from rigidly colliding with the second bracket 240, thereby preventing the functional part 220 and the second bracket 240 from being damaged.

The first elastic member 261, the second elastic member 262 and the third elastic member 263 may be springs, and of course, other elastic structures may be adopted, which is not limited herein.

The present application discloses a specific structure of the functional portion 220, but of course, other structures are also possible, and the present application is not limited thereto. Specifically, the functional unit 220 may include a main body 221 and two extending protrusions 222 extending from the main body 221 toward the inner cavity 110, the two extending protrusions 222 may be located on two sides of the main body 221, an accommodating space is defined by the two extending protrusions 222 and the main body 221, a portion of the second bracket 240 is located in the accommodating space, a clamping protrusion 2221 may be disposed on one side of at least one of the extending protrusions 222 facing the second bracket 240, the second bracket 240 is provided with a clamping groove 243, the clamping protrusion 2221 may be located in the clamping groove 243, the clamping protrusion 2221 may slide in the clamping groove 243 along an axial direction of the through hole, one end of the third elastic member 263 may be connected to the main body 221, and one end of the third elastic member 263 may be connected to the second bracket 240.

In this scheme, two extension protrusions 222 and the main body 221 enclose an accommodation space, a portion of the second bracket 240 is located in the accommodation space, and meanwhile, the clamping protrusion 2221 on the extension protrusion 222 is in clamping fit with the clamping groove 243 on the second bracket 240, so that the functional portion 220 is in clamping fit with the second bracket 240, and at this time, the connection structure of the functional portion 220 and the second bracket 240 is simple and convenient.

In another alternative, one end of the extending protrusion 222 away from the main body 221 and the side of the extending protrusion 222 away from the second bracket 240 may be provided with a chamfer, and the above limiting protrusion 251 may also be provided with a chamfer, and the chamfer of the extending protrusion 222 and the chamfer of the limiting protrusion 251 can slide relatively.

In another alternative embodiment, the functional element 200 may be a key module, the functional portion 220 may be a key, the key module may further include a circuit board element 280, and the circuit board element 280 is disposed on the second support 240.

The function part 220 may have a pressing preset distance, and when the moving distance of the function part 220 is less than or equal to the pressing preset distance in a case where the function part 220 is in the extended state, the function part 220 presses the circuit board assembly 280. When the moving distance of the functional portion 220 is greater than the pressing preset distance, the functional portion 220 drives the first limiting member 250 to separate from the second bracket 240.

In this scheme, when the key module is used, the driving mechanism 210 drives the keys to extend out of the casing 100, so that the keys protrude out of the casing 100, the positions of the keys are more obvious, and in the control process, a user presses the keys by feel, and the keys are also easily positioned, so that the possibility of pressing the keys is reduced. When the key is not used, the key can be retracted and hidden in the housing 100, so that the appearance and normal use of the electronic device are not affected. In the embodiment of the application, the keys can be mainly used as game keys.

In addition, when the pressing force applied to the key is too large, the moving distance of the key exceeds the preset pressing distance, so that the key drives the first limiting member 250 to separate from the second bracket 240, and the key can drive the second bracket 240 to retract, thereby preventing the key from being damaged.

Alternatively, the pressing preset distance of the function part 220 may be 0.7mm, and when the moving distance of the function part 220 is less than 0.7mm, the function part 220 normally operates. When the moving distance of the functional portion 220 is greater than 0.7mm and exceeds the pressing preset distance, the continuous pressing of the functional portion 220 drives the first limiting member 250 to be away from the second bracket 240, and finally contacts the limiting of the second bracket 240, and the functional portion 220 and the second bracket 240 are retracted into the housing 100 together. Of course, in order to secure the safety of the function part 220, the pressing preset distance may be floated upward by 0.2 mm.

In another alternative embodiment, the second bracket 240 may include adjacent first and second sides, and specifically, the first side may be one side of a plane formed by the length and thickness or the width and thickness of the housing 100, and the second side may be one side of a plane formed by the length and width. The first side is disposed opposite to the function part 220.

The circuit board assembly 280 may include a circuit board 281 and a snap tab 283, the circuit board 281 may be disposed on the second support 240 and extend from the second side to the first side, and the snap tab 283 may be disposed on the first side and electrically connected to the circuit board 281.

In this scheme, the circuit board 281 can extend to a side where the key is located, and since the side where the key is located is generally located on a frame of the electronic device, the size is small, and thus the size of the circuit board 281 is small. In the present application, the circuit board 281 can extend from the side with the larger size to the side with the smaller size, so that the area of the circuit board 281 is increased, and the use performance of the key module can be increased.

Alternatively, the circuit board 281 may be a printed circuit board or a flexible circuit board, or a rigid-flex board, although other structures may also be adopted, and this is not limited herein.

In the above embodiment, the snap-dome 283 has stable resilience, and the snap-dome 283 has better conductivity, so that the failure probability of the key module is very low, and the key module has higher reliability.

In another alternative embodiment, the second bracket 240 defines a receiving groove extending from the second side to the first side, and the circuit board 281 may be disposed in the receiving groove.

In order to prevent the third elastic element 263 from being compressed excessively between the functional part 220 and the second bracket 240, which results in the elastic failure of the third elastic element 263. In another alternative embodiment, a side of the functional part 220 facing the second bracket 240 may be provided with a mounting post 223, and a portion of the third elastic member 263 may be sleeved on the mounting post 223. The moving distance of the functional part 220 with respect to the second bracket 240 may be greater than or equal to the distance between the end of the mounting post 223 facing away from the functional part 220 and the second bracket 240. That is, the moving distance of the functional part 220 with respect to the second bracket 240 may be greater than or equal to the distance from the free end of the mounting post 223 to the second bracket 240.

In this embodiment, after the free end of the mounting post 223 contacts the second support 240, the third elastic member 263 is not yet in the extreme compression state, so that the third elastic member 263 is prevented from being compressed excessively, thereby preventing the risk of elastic failure of the third elastic member 263 and improving the reliability of the electronic device.

In the above solution, since the first bracket 230 and the second bracket 240 are elastically connected by the first elastic member 261, when the through hole of the electronic device faces downward, the weight of the second bracket 240 and the functional part 220 is applied to the second elastic member 262, so that the second elastic member 262 is extended, and the second bracket 240 and the functional part 220 are excessively extended.

For this reason, in another alternative embodiment, the functional assembly 200 may further include a second limiting member 270, the second limiting member 270 may be movably disposed in the inner cavity 110, the first bracket 230 drives the second limiting member 270 to move during the moving process, and when the functional portion 220 is in the extending state or the retracting state, the second limiting member 270 is in limiting engagement with the second bracket 240 along the extending direction of the functional portion 220.

In a specific working process, when the functional portion 220 is in the retracted state, the second limiting member 270 is in limiting fit with a position of the second bracket 240 along the extending direction of the functional portion 220, so that the second limiting member 270 is fixed in the inner cavity 110, and the second bracket 240 is prevented from driving the functional portion 220 to extend. When the functional portion 220 is fully extended, the second limiting member 270 is in limiting fit with another position of the second bracket 240 along the extending direction of the functional portion 220, so as to prevent the functional portion 220 from being excessively extended.

In this embodiment, the second stopper 270 limits the second bracket 240 regardless of whether the functional part 220 is in the extended state or the retracted state, so that the second bracket 240 and the functional part 220 can be prevented from being excessively extended.

The application discloses a specific structure of the second limiting member 270, and the second limiting member 270 may also have other structures, which is not limited herein. Specifically, the second limiting member 270 may be provided with a sliding recess 271 penetrating along the axial direction of the through hole, an inner wall surface opposite to the sliding recess 271 may be a second inclined surface and a third inclined surface, the second inclined surface and the third inclined surface may incline toward one side of the through hole, the two opposite sides of the first bracket 230 extend to form a second protrusion 232 and a third protrusion 233, the second protrusion 232 and the second inclined surface may be in sliding fit, and the third protrusion 233 may be in sliding fit with the third inclined surface.

When the driving mechanism 210 drives the first bracket 230 to move along the retraction direction of the functional part 220, the second protrusion 232 slides along the second inclined surface, so that the second limiting member 270 is in limiting engagement with the second bracket 240 when the functional part 220 is in the retracted state.

When the driving mechanism 210 drives the first bracket 230 to move along the extending direction of the functional part 220, the third protrusion 233 may slide along the third inclined surface, so that the second limiting member 270 is in limiting fit with the second bracket 240 when the functional part 220 is in the extending state.

In this embodiment, the inner wall surface of the sliding recess 271 is engaged with the first protrusion 231 and the second protrusion 232 on the first bracket 230, so that the second limiting member 270 is driven to move away from or close to the second bracket 240 during the movement of the first bracket 230 along the extending or retracting direction of the functional unit 220, so as to limit the engagement of the second limiting member 270 and the second bracket 240 at different positions. The scheme has simple and reliable structure and is easy to realize.

Further, the second bracket 240 extends along the thickness direction of the housing 100 to form a first limiting convex part 242, the first limiting convex part 242 is provided with a first limiting surface 2421, a second limiting surface 2422 and a third limiting surface 2423 which are sequentially connected, the first limiting surface 2421 and the third limiting surface 2423 are obliquely arranged along one side of the first limiting convex part 242, which is away from the functional part 220, at this time, the first limiting convex part 242 is of a trapezoid structure, the second limiting surface 2422 is a top surface of the trapezoid structure, and the first limiting surface 2421 and the third limiting surface 2423 are two side surfaces of the trapezoid structure.

Under the condition that the functional portion 220 is in the retracted state, the second limiting member 270 may be lapped on the second limiting surface 2422 and is in limiting fit with the second limiting surface 2422 along the extending direction of the functional portion 220.

When the functional portion 220 is in the extended state, the second limiting element 270 may overlap the first limiting surface 2421 and/or the third limiting surface 2423, and limit-cooperate with the first limiting surface 2421 and/or the third limiting surface 2423 along the extending direction of the functional portion 220.

In this embodiment, the first limiting protrusion 242 has a trapezoid structure, and the two surfaces of the trapezoid structure can limit and cooperate with the functional portion 220 in the retracted state and the extended state, thereby simplifying the structure of the second limiting member 270.

In another alternative embodiment, the second bracket 240 may be provided with a first guide protrusion 244, the first bracket 230 may be provided with a second guide protrusion 234, the first guide protrusion 244 may be provided with a guide groove, the second guide protrusion 234 may be slidably fitted with the guide groove along the axial direction of the through hole, the first elastic member 261 may be provided in the guide groove, and a portion of the first elastic member may be sleeved on the second guide protrusion 234. In this scheme, the guide groove and the second guide protrusion 234 can assist in limiting the moving direction of the second bracket 240, so as to prevent the second bracket 240 from deflecting during the moving process, thereby improving the moving accuracy of the second bracket 240, and further preventing the functional part 220 from scraping against the through hole of the housing 100 during the process of entering and exiting the housing 100.

Alternatively, the second guide protrusion 234 may be provided with a guide groove, the first guide protrusion 244 may be slidably fitted with the guide groove along the axial direction of the through hole, and the first elastic member 261 is disposed in the guide groove, and a part of the first elastic member may be sleeved on the first guide protrusion 244. The effect achieved by this scheme is the same as that achieved by the above scheme, and therefore, the detailed description is omitted.

In another alternative embodiment, two first limiting members 250 and two second limiting members 270 may be provided, and the two first limiting members 250 and the two second limiting members 270 may be symmetrically distributed along the central axis of the through hole. Of course, the first protrusion 231 engaged with the first limiting member 250 and the second protrusion 232 and the third protrusion 233 engaged with the second limiting member 270 may be two, and both are symmetrically distributed along the central axis of the through hole.
