Description

Cover assembly and electronic equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 15, 2023, with application number 202311547599.6 and application name “Cover assembly and electronic device”. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a cover assembly and an electronic device. Background Art

[0003] With the development of electronic devices, cameras are now commonplace on mobile phones, tablets, computers, and other terminal devices. Some electronic devices have retractable cameras, allowing them to be extended or retracted. To protect the cameras, many cameras are equipped with protective covers. When the camera is extended or retracted, the protective cover also moves with the camera.

[0004] However, when users use electronic devices, they often drop or bump into them. When the camera cover is extended outside the electronic device, if the electronic device falls or bumps into something, the camera cover will be hit hard, which may cause damage to the camera cover.

[0005] Summary of the Invention

[0006] The present application provides a cover assembly and an electronic device, wherein a buffer device is provided inside the cover assembly. When the cover assembly is impacted by an external impact, the buffer device can play a buffering role, thereby preventing the cover assembly from being damaged.

[0007] In the first aspect, the present application provides a cover assembly, which is provided on an electronic device. The electronic device can be a terminal device such as a mobile phone, a tablet, a computer, a PC camera, etc. The cover assembly is used to protect the camera on the electronic device. The cover assembly includes: a base, a cover, a lifting device and a buffer device. Among them, the cover is arranged on one side of the base along a first direction. The lifting device is provided on the base, and the lifting device is used to drive the cover to rise in a first direction or descend in a second direction relative to the base, and the second direction is the opposite direction of the first direction. The buffer device extends along the first direction, and the buffer device can produce elastic deformation along the first direction. One end of the buffer device is in contact with the cover, and the other end is in contact with the driving end of the lifting device.

[0008] When the lifting device drives the cover to rise, the driving end of the lifting device moves in a first direction. Since the buffer device is disposed between the lifting device and the cover, the driving end of the lifting device drives the buffer device and the cover to move together in the first direction, so that the cover at least partially extends outside the electronic device. When the cover in the rising state is subjected to an external force in a second direction, that is, when the cover is subjected to a force from outside the cover assembly (such as external pressure, impact force, etc.), the cover can retract in the second direction relative to the driving end of the lifting device. At this time, the buffer device is squeezed and elastically deformed, providing a buffer for the retraction process of the cover, thereby reducing external impact damage to the cover.

[0009] In some implementations of the present application, the buffer device is a wave spring, and when the cover is subjected to an external force along the second direction, the wave spring is in a compressed state. For example, when the wave spring is applied to a camera protective cover of an electronic device, the elastic coefficient of the wave spring can be 0.5-5N / mm. Compared with ordinary linear springs, wave springs have the characteristics of small initial height (the height of the wave spring when not subjected to external force), small compressed height (the height of the wave spring when compressed to the maximum limit) and large elastic coefficient. By adopting a wave spring, the present application can save the installation space of the buffer device along the first direction, thereby reducing the height of the cover protruding from the electronic device when it rises to the top.

[0010] In some implementations of the present application, the lifting device includes a fixed part and a movable part. The fixed part is arranged on the base, and the movable part is the driving end of the lifting device. The fixed part can drive the movable part to move relative to the base in the first direction or the second direction to drive the cover body to extend and retract relative to the base.

[0011] The present application does not limit the specific structures of the fixed part and the movable part. Any mechanism that can drive the cover to move along the first direction or the second direction falls within the protection scope of the present application.

[0012] In some implementations of the present application, the fixed portion includes a first sleeve, and the movable portion includes a second sleeve. The axis of the first sleeve and the axis of the second sleeve are both parallel to the first direction, and the first sleeve and the second sleeve are arranged in a mutually nested manner. A sliding groove is provided on the circumferential surface of one of the first sleeve and the second sleeve, and a slider is provided on the circumferential surface of the other sleeve. The slider is inserted into the sliding groove and can slide along the sliding groove. The sliding groove includes an inclined section, which is inclined relative to a first plane, and the first plane is perpendicular to the first direction. When the first sleeve rotates around its axis, the inclined section and the slider can drive the second sleeve to move in the first direction or the second direction to drive the movable portion to move.

[0013] In some implementations of the present application, the second sleeve is disposed externally of the first sleeve, the slide groove is disposed on the outer wall of the first sleeve, and the slider is disposed on the inner wall of the second sleeve. The present application further includes a drive unit, the drive end of the drive unit being connected to the first sleeve, the drive unit being configured to drive the first sleeve to rotate. For example, the drive unit may be a motor.

[0014] When the driving unit drives the first sleeve to rotate, the inclined section of the slide groove rotates with the first sleeve. At this time, the inclined section will apply a component force along the axial direction of the first sleeve to the slider, causing the slider and the second sleeve connected to the slider to move in the first direction or the second direction to drive the cover to extend and retract.

[0015] Compared to using a linearly moving device such as an electric push rod to drive the movement of the moving part, the present application uses a rotating first sleeve to drive the movement of the moving part, which can increase the thrust on the moving part and make the telescopic movement of the cover body smoother. In addition, when the electric push rod drives the moving part to move, the driving end of the electric push rod is in point contact with the moving part, which can easily cause the moving part to be unevenly stressed, causing the moving part to become stuck during movement, or causing the moving part and the cover body to become skewed when the cover body is impacted by external forces. The present application sets the fixed part and the moving part into a cylindrical shape, arranges the first sleeve and the second sleeve on each other, and drives the movement of the second sleeve by rotating the first sleeve. This can make the moving part run smoothly and prevent the moving part and the cover body from becoming skewed when the cover body is impacted by external forces.

[0016] In some implementations of the present application, the slide further includes a first horizontal section and a second horizontal section, wherein the first horizontal section is connected to one end of the inclined section and is parallel to the first plane; the second horizontal section is connected to the other end of the inclined section and is parallel to the first plane. For example, the first horizontal section is located on a side away from the base, and when the cover rises to its topmost point, the slider slides into the first horizontal section; the second horizontal section is located on a side closer to the base, and when the cover descends to its bottommost point, the slider slides into the second horizontal section.

[0017] By providing a first horizontal section and a second horizontal section at each end of the inclined section, the present application enables the slider to slide into the first and second horizontal sections, respectively, to achieve self-locking when the cover rises to the top and lowers to the bottom, thereby maintaining a more stable position of the cover when it rises to the top and lowers to the bottom. Furthermore, when a linearly movable device such as an electric push rod is used to drive the movement of the movable portion, although a buffer device is provided between the cover and the movable portion to provide a buffering effect when the cover is impacted by external forces, the movable portion will still be subject to a certain force in the second direction, and the movable portion will directly transmit this force to the electric push rod, which can easily damage the electric push rod. By utilizing a rotating first sleeve to drive the movement of the movable portion, the present application enables the slider to slide into the first horizontal section when the cover rises to the top. When the cover body is hit by an external force along the second direction, the slider on the moving part will apply the external force it receives to the first horizontal section. Since the extension direction of the first horizontal section is perpendicular to the axial direction of the first sleeve, the slider will not generate a component force along the circumference of the first sleeve on the first horizontal section, thereby preventing the first sleeve from rotating in the opposite direction, and further avoiding damage to the drive unit caused by the reverse rotation of the drive unit (i.e., the motor).

[0018] In some implementations of the present application, the inner wall of the second sleeve is provided with multiple sliders, each of which is evenly distributed along the circumference of the second sleeve. The outer wall of the first sleeve is provided with multiple chute grooves, each of which is equal in number to each of the sliders and corresponds one-to-one. By providing multiple sliders and chute grooves, the present application can achieve balanced force on the second sleeve, thereby improving the movement stability of the second sleeve.

[0019] In some implementations of the present application, a mounting hole extending along a first direction is provided on the base, a first sleeve is inserted into the mounting hole, a first annular limiting groove is provided on the circumferential surface of the mounting hole, a first limiting protrusion is provided on the outer wall of the first sleeve, the first limiting protrusion is inserted in the first limiting groove, the first limiting protrusion can slide relative to the first limiting groove along the circumferential direction of the first limiting groove, and the upper wall and lower wall of the first limiting groove can block the first limiting protrusion from moving axially along the first limiting groove.

[0020] In some implementations of the present application, a limiting mechanism is provided between the base and the second sleeve, and the limiting mechanism is used to limit the second sleeve from rotating relative to the base around the axis of the second sleeve.

[0021] In some implementations of the present application, the limiting mechanism includes a third sleeve and a second limiting protrusion. The third sleeve is disposed on the base, and a second limiting groove extending in a first direction is provided on the wall of the third sleeve. The second limiting protrusion is disposed on the second sleeve and inserted into the second limiting groove. The second limiting protrusion can slide relative to the second limiting groove in the first direction or the second direction, and the sidewall of the second limiting groove can prevent the second limiting protrusion from moving circumferentially along the third sleeve. For example, the third sleeve coincides with the axis of the mounting hole, the third sleeve is provided with a plurality of second limiting grooves arranged sequentially along the circumference of the third sleeve, and the second sleeve is provided with a plurality of second limiting protrusions arranged sequentially along the circumference of the second sleeve, each second limiting groove having a second limiting protrusion inserted therein, and each second limiting groove can serve as a stop for each second limiting protrusion along the circumference of the second sleeve, thereby ensuring uniform force on the second sleeve.

[0022] In some implementations of the present application, the housing includes a cylindrical body and an end plate. The cylindrical body extends in a first direction and is sleeved onto the exterior of the second sleeve and the buffer device. The end plate is disposed on an end surface of the cylindrical body in a second direction, with one end of the buffer device in contact with the end plate and the other end in contact with the second sleeve.

[0023] In some implementations of the present application, a third limiting protrusion is provided on the inner wall of the cylinder, and the third limiting protrusion is inserted into each second limiting groove. The third limiting protrusion can slide relative to the second limiting groove in the first direction or the second direction, and the sidewall of the second limiting groove can prevent the third limiting protrusion from moving along the circumferential direction of the third sleeve. For example, the third sleeve is provided with a plurality of second limiting grooves arranged in sequence along the circumference of the third sleeve, and the cylinder is provided with a plurality of third limiting protrusions arranged in sequence along the circumference of the cylinder. A third limiting protrusion is inserted into each second limiting groove, and each second limiting groove can respectively serve as a stop for each third limiting protrusion along the circumference of the cylinder, thereby ensuring that the cylinder is subjected to uniform force.

[0024] In some implementations of the present application, the second limiting protrusion is located between the buffer device and the third limiting protrusion along the first direction. When the second sleeve moves in the first direction, the second sleeve pushes the cover body in the first direction via the buffer device; when the second sleeve moves in the second direction, the second limiting protrusion can contact the third limiting protrusion and apply a thrust to the third limiting protrusion to push the cover body in the second direction.

[0025] In a second aspect, the present application provides an electronic device comprising a housing and a cover assembly as in the first aspect, wherein the cover assembly is disposed on the housing, and the cover can extend to the outside of the housing or retract into the inside of the housing.

[0026] In some implementations of the present application, the electronic device further includes a camera, and the cover of the cover assembly is disposed on the camera. For example, the camera can be disposed in the cavity of the first cylinder, and the cover assembly can protect the camera. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0059] An embodiment of the present application provides an electronic device including a cover assembly, which can protect other components (e.g., a camera) in the electronic device. When the cover assembly is subjected to an external impact, the embodiment of the present application can reduce or prevent damage to the cover assembly.

[0060] In this application, the electronic device may be a mobile phone, a tablet, a computer, a PC camera, etc., and this application does not limit this. The mobile phone is used as an example of an electronic device for introduction below.

[0061] Figures 1 to 2B illustrate exemplary structural diagrams of electronic devices provided by embodiments of the present application. Figure 1 is an external view of the electronic device, Figure 2A is a schematic diagram of the cover assembly in an extended state, and Figure 2B is a schematic diagram of the cover assembly in a retracted state.

[0062] 2A and 2B , the electronic device 10 includes a housing 100, a camera 200, and a cover assembly 300. The camera 200 has a lifting function and can be extended to the outside of the housing 100 or retracted into the housing 100. The cover assembly 300 includes a cover 2, which is disposed on the outside of the camera 200 and can be raised and lowered in conjunction with the camera 200 to protect the camera 200. For example, referring to FIG2A , when the camera 200 is extended to the outside of the housing 100, the cover 2 rises in conjunction with the camera 200; referring to FIG2B , when the camera 200 is retracted into the housing 100, the cover 2 descends in conjunction with the camera 200.

[0063] In the various figures herein, the X-axis direction is the thickness direction of the electronic device, the direction from the front of the electronic device to the back of the electronic device is the positive direction of the X-axis (denoted as the X1 direction, as the first direction), and the opposite direction is the negative direction of the X-axis (denoted as the X2 direction, as the second direction). For ease of understanding, hereinafter, the X1 direction is used as an example of the rising direction of the camera and the cover, and the X2 direction is used as an example of the descending direction of the camera and the cover. However, it will be understood that the present application is not limited to this. In other embodiments, the rising / descending direction of the camera and the cover may also be other directions, for example, the length direction of the electronic device (as shown in the Y direction in Figure 1), etc.

[0064] When a user uses an electronic device, the electronic device may often be dropped or bumped. When the cover 2 extends outside the housing 100, if the electronic device is dropped or bumped, the cover assembly 300 may be subjected to a large impact, which may cause damage to the cover assembly 300.

[0065] The present application provides a cover assembly, which is provided on an electronic device. Referring to Figures 3 and 4, the cover assembly includes: a base 1, a cover 2, a lifting device 3 and a buffer device 6. Among them, the cover 2 is arranged on one side of the base 1 along the X1 direction. The lifting device 3 is provided on the base 1, and the lifting device 3 is used to drive the cover 2 to rise along the X1 direction or descend along the X2 direction relative to the base 1. The buffer device 6 extends along the X direction, and the buffer device 6 can produce elastic deformation along the X direction. One end of the buffer device 6 is in contact with the cover 2, and the other end is in contact with the driving end of the lifting device 3.

[0066] Figure 4 is a schematic diagram of the structure of the cover 2 when it rises to the top, and Figure 5 is a schematic diagram of the structure of the cover 2 when it descends to the bottom. When the lifting device 3 drives the cover 2 to rise, the driving end of the lifting device 3 moves along the X1 direction. Since the buffer device 6 is located between the lifting device 3 and the cover 2, the driving end of the lifting device 3 will drive the buffer device 6 and the cover 2 to move together along the X1 direction, so that the cover 2 at least partially extends outside the electronic device. During this process, the cover 2 may exert its weight on the buffer device 6. Since the weight of the cover 2 on the electronic device is generally light, the deformation of the buffer device 6 is small and will not affect the movement of the cover 2 along the X1 direction.

[0067] When the cover 2 in the raised state is subjected to an external force in the X2 direction, that is, when the cover 2 is subjected to a force from outside the cover assembly 300 (such as external pressure, impact, etc.), the cover 2 can retract in the X2 direction relative to the driving end of the lifting device 3, as shown in Figure 6. At this time, the buffer device 6 is squeezed and elastically deformed, providing a buffer for the retraction process of the cover 2, thereby reducing the impact damage to the cover 2 caused by the external environment.

[0068] In some implementations of the present application, referring to Figures 7 and 8, the buffer device 6 is a wave spring, and when the cover body 2 is subjected to an external force along the X2 direction, the wave spring is in a compressed state. For example, when the wave spring is applied to a camera protective cover of an electronic device, the elastic coefficient of the wave spring can be 0.5-5N / mm. Compared with ordinary linear springs, the wave spring has the characteristics of a small initial height (the height of the wave spring when not subjected to external force), a small compressed height (the height of the wave spring when compressed to the maximum limit) and a large elastic coefficient. By adopting a wave spring, the present application can save the installation space of the buffer device 6 along the X1 direction, thereby reducing the height of the cover body 2 protruding from the electronic device when it rises to the top.

[0069] In some implementations of the present application, referring to Figure 4, the lifting device 3 includes a fixed part 4 and a movable part 5. The fixed part 4 is arranged on the base 1, and the movable part 5 is the driving end of the lifting device 3. The fixed part 4 can drive the movable part 5 to move relative to the base 1 along the X direction to drive the cover body 2 to extend and retract relative to the base 1.

[0070] The present application does not limit the specific structures of the fixed portion 4 and the movable portion 5 , and any mechanism that can drive the cover body 2 to move along the X direction falls within the protection scope of the present application.

[0071] In some implementations of the present application, referring to Figures 9 to 12, the fixed portion 4 includes a first sleeve 41, and the movable portion 5 includes a second sleeve 51. The axes of the first sleeve 41 and the second sleeve 51 are both parallel to the X-direction. The first sleeve 41 and the second sleeve 51 are nested together, and the buffer device 6 is disposed between the second sleeve 51 and the housing 2. A chute 42 is provided on the circumferential surface of one of the first sleeve 41 and the second sleeve 51, and a slider 52 is provided on the circumferential surface of the other. The slider 52 is inserted into the chute 42 and can slide along the chute 42. The chute 42 includes an inclined section 421, which is inclined relative to a first plane, which is a plane perpendicular to the X-direction. When the first sleeve 41 rotates about its axis, the inclined section 421 and the slider 52 can drive the second sleeve 51 to move in the X-direction, thereby driving the movable portion 5 to move.

[0072] In some implementations of the present application, referring to Figures 9 and 12 , the second sleeve 51 is sleeved on the outside of the first sleeve 41, the slide groove 42 is provided on the outer wall of the first sleeve 41, and the slider 52 is provided on the inner wall of the second sleeve 51. The present application further includes a drive unit (not shown), the drive end of the drive unit being connected to the first sleeve 41, and the drive unit being configured to drive the first sleeve 41 to rotate. For example, the drive unit may be a motor.

[0073] When the driving unit drives the first sleeve 41 to rotate, the inclined section 421 of the slide 42 rotates along with the first sleeve 41. At this time, the inclined section 421 will apply a component of force along the axial direction of the first sleeve 41 to the slider 52, causing the slider 52 and the second sleeve 51 connected to the slider 52 to move along the X1 direction or the X2 direction, thereby driving the cover 2 to extend and retract. Specifically, in some implementations, the two ends of the buffer device 6 are respectively connected to the cover 2 and the second sleeve 51. When the second sleeve 51 moves along the X1 direction, the second sleeve 51 will apply a thrust along the X1 direction to the buffer device 6, so that the buffer device 6 pushes the cover 2 to extend along the X1 direction to the outside of the electronic device. When the second sleeve 51 moves along the X2 direction, the second sleeve 51 will apply a pulling force along the X2 direction to the buffer device 6, so that the buffer device 6 pulls the cover 2 to retract along the X2 direction into the interior of the electronic device. In some other implementations, when the X direction is vertical, the weight of the buffer device 6 and the cover body 2 both acts on the second sleeve 51. Therefore, the ends of the buffer device 6 can be in contact with the cover body 2 and the second sleeve 51 respectively, and do not necessarily need to be connected to the cover body 2 and the second sleeve 51. When the second sleeve 51 moves in the X1 direction, the second sleeve 51 will lift the buffer device 6 and the cover body 2 above it and move them together in the X1 direction. When the second sleeve 51 moves in the X2 direction, because the buffer device 6 and the cover body 2 are always pressed against the upper surface of the second sleeve 51 due to the action of gravity, the buffer device 6 and the cover body 2 will move along with the second sleeve 51 in the X2 direction.

[0074] Compared to using a linearly moving device such as an electric push rod to drive the movement of the cover body 2, the present application uses a rotating first sleeve 41 and a moving part 5 that is mounted on the first sleeve 41 to drive the movement of the cover body 2, which can increase the thrust on the cover body 2 and make the telescopic movement of the cover body 2 smoother. In addition, when the electric push rod drives the cover body 2 to move, the driving end of the electric push rod is in point contact with the cover body 2, which can easily cause uneven force on the cover body 2, resulting in the cover body 2 being stuck during movement or causing the cover body 2 to tilt when impacted by external forces. The present application makes the cover body 2 run smoothly by mounting the first sleeve 41 and the second sleeve 51 on each other, and drives the second sleeve 51 to move by the rotating first sleeve 41, which can prevent the cover body 2 from tilting when impacted by external forces.

[0075] In some implementations of the present application, referring to FIG9 , the slide 42 further includes a first horizontal section 422 and a second horizontal section 423. The first horizontal section 422 is connected to one end of the inclined section 421 and is parallel to the first plane; the second horizontal section 423 is connected to the other end of the inclined section 421 and is parallel to the first plane. For example, the first horizontal section 422 is located on a side away from the base 1. When the cover 2 rises to its topmost point, the slider 52 slides into the first horizontal section 422. The second horizontal section 423 is located on a side closer to the base 1. When the cover 2 descends to its bottommost point, the slider 52 slides into the second horizontal section 423.

[0076] By providing a first horizontal section 422 and a second horizontal section 423 at each end of the inclined section 421, the present application enables the slider 52 to slide into the first horizontal section 422 and the second horizontal section 423, respectively, to achieve self-locking when the cover 2 rises to the top and descends to the bottom, thereby maintaining a more stable position of the cover 2 when rising to the top and descending to the bottom. Furthermore, when a linearly movable device such as an electric push rod is used to drive the movement of the movable portion 5, although a buffer device 6 is provided between the cover 2 and the movable portion 5 to provide a buffering effect when the cover 2 is impacted by external forces, the movable portion 5 is still subject to a certain force acting in the X2 direction, and the movable portion 5 directly transmits this force to the electric push rod, which can easily damage the electric push rod. By utilizing a rotating first sleeve 41 to drive the movement of the movable portion 5, the present application enables the slider 52 to slide into the first horizontal section 422 when the cover 2 rises to the top. If the housing 2 is struck by an external force in the X2 direction, the slider 52 on the movable portion 5 will apply the external force to the first horizontal section 422. Since the first horizontal section 422 extends perpendicular to the axial direction of the first sleeve 41, the slider 52 will not generate a force component along the circumferential direction of the first sleeve 41 on the first horizontal section 422, thereby preventing the first sleeve 41 from rotating in the reverse direction and thus avoiding damage to the drive unit (e.g., a motor) caused by reverse rotation.

[0077] In some implementations of the present application, referring to Figures 9 and 10 , a plurality of sliders 52 are provided on the inner wall of the second sleeve 51, each slider 52 being evenly distributed along the circumference of the second sleeve 51. A plurality of chute grooves 42 are provided on the outer wall of the first sleeve 41, with an equal number of chute grooves 42 and a one-to-one correspondence between sliders 52. By providing multiple sliders 52 and chute grooves 42, the present application can achieve balanced force on the second sleeve 51, thereby improving the movement stability of the second sleeve 51.
