Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a cover assembly and an electronic equipment. Background Art

[0002] With the development of electronic devices, mobile phones, tablets, computers and other terminal devices are generally equipped with cameras. In some electronic devices, the camera has a telescopic function, which can be extended to the outside of the electronic device or retracted into the electronic device. In order to protect the camera, many cameras are equipped with camera protective covers on the outside. When the camera is extended, the camera protective cover can also be extended with the camera.

[0003] However, when users use electronic devices, the electronic devices often fall or bump into each other. When the camera protective cover is extended to the outside of the electronic device, if the electronic device falls or bumps into each other, the camera protective cover will be hit hard, which may cause damage to the camera protective cover. Summary of the invention

[0004] 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 the outside, the buffer device can play a buffering role, thereby preventing the cover assembly from being damaged.

[0005] In the first aspect, the present application provides a cover assembly, which is arranged 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 arranged 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 body, and the other end is in contact with the driving end of the lifting device.

[0006] When the lifting device drives the cover body to rise, the driving end of the lifting device moves along the first direction. Since the buffer device is arranged between the lifting device and the cover body, the driving end of the lifting device will drive the buffer device and the cover body to move along the first direction together, so that the cover body at least partially extends to the outside of the electronic device. When the cover body in the rising state is subjected to an external force along the second direction, that is, when the cover body is subjected to a force from outside the cover body assembly (such as external pressure, impact force, etc.), the cover body can retract along the second direction relative to the driving end of the lifting device. At this time, the buffer device is squeezed to produce elastic deformation, providing a buffer for the retraction process of the cover body, thereby reducing the impact damage to the cover body from the outside.

[0007] In some implementations of the present application, the buffer device is a wave spring, and when the cover body is subjected to an external force along the second direction, the wave spring is in a compressed state. Exemplarily, 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 body protruding from the electronic device when it rises to the top.

[0008] 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 in a first direction or a second direction relative to the base to drive the cover body to extend and retract relative to the base.

[0009] The present application does not limit the specific structures of the fixed part and the movable part, and 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.

[0010] 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 mutually sleeved. A slide 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 slide groove and can slide along the slide groove. The slide 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 second sleeve can be driven to move in the first direction or the second direction through the inclined section and the slider to drive the movable portion to move.

[0011] In some implementations of the present application, the second sleeve is sleeved on the outside of the first sleeve, the slide groove is provided on the outer wall of the first sleeve, and the slider is provided on the inner wall of the second sleeve. The present application also includes a drive unit, the drive end of the drive unit is connected to the first sleeve, and the drive unit is used to drive the first sleeve to rotate. Exemplarily, the drive unit can be a motor.

[0012] 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, so that the slider and the second sleeve connected to the slider move in the first direction or the second direction to drive the cover body to extend and retract.

[0013] Compared to using a linear 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 get stuck during movement, or causing the moving part and the cover body to be skewed when the cover body is hit by an external force. The present application sets the fixed part and the moving part to a cylindrical shape, arranges the first sleeve and the second sleeve on each other, and drives the second sleeve to move by rotating the first sleeve, so that the moving part can run smoothly and the moving part and the cover body can be prevented from being skewed when the cover body is hit by an external force.

[0014] In some implementations of the present application, the slide also includes a first horizontal section and a second horizontal section, the first horizontal section is connected to one end of the inclined section, and the first horizontal section is parallel to the first plane; the second horizontal section is connected to the other end of the inclined section, and the second horizontal section is parallel to the first plane. Exemplarily, the first horizontal section is arranged on a side away from the base, and when the cover rises to the top, the slider slides into the first horizontal section; the second horizontal section is arranged on a side close to the base, and when the cover descends to the bottom, the slider slides into the second horizontal section.

[0015] The present application sets a first horizontal section and a second horizontal section at both ends of the inclined section, respectively, so that when the cover rises to the top and when it falls to the bottom, the slider can slide into the first horizontal section and the second horizontal section to achieve self-locking, so that the position of the cover when it rises to the top and when it falls to the bottom remains more stable. In addition, when a linear moving device such as an electric push rod is used to drive the moving part to move, although a buffer device is provided between the cover and the moving part, which can play a buffering role when the cover is hit by an external force, even so, the moving part will still be subjected to a certain force in the second direction, and the moving part will directly transmit the force to the electric push rod, which is easy to damage the electric push rod. The present application uses a rotating first sleeve to drive the moving part to move, so that when the cover rises to the top, the slider can slide into the first horizontal section. 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 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 on the first horizontal section along the circumferential direction of the first sleeve, thereby preventing the first sleeve from rotating in the opposite direction, thereby avoiding damage to the drive unit (i.e., the motor) caused by the reverse rotation of the drive unit.

[0016] In some implementations of the present application, a plurality of sliders are provided on the inner wall of the second sleeve, and the sliders are evenly arranged along the circumference of the second sleeve, and a plurality of slide grooves are provided on the outer wall of the first sleeve, and the number of the slide grooves is equal to and corresponds to the sliders. The present application can balance the force on the second sleeve by providing a plurality of sliders and slide grooves, thereby improving the movement stability of the second sleeve.

[0017] 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 the lower wall of the first limiting groove can block the first limiting protrusion from moving axially along the first limiting groove.

[0018] 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 rotation of the second sleeve relative to the base around the axis of the second sleeve.

[0019] In some implementations of the present application, the limiting mechanism includes a third sleeve and a second limiting protrusion. The third sleeve is arranged on the base, and a second limiting groove extending in the first direction is provided on the wall of the third sleeve. The second limiting protrusion is arranged on the second sleeve, and the second limiting protrusion is inserted in 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 side wall of the second limiting groove can block the second limiting protrusion from moving in the circumferential direction of the third sleeve. Exemplarily, the third sleeve coincides with the axis of the mounting hole, and the third sleeve is provided with a plurality of second limiting grooves arranged in sequence along the circumference of the third sleeve, and the second sleeve is provided with a plurality of second limiting protrusions arranged in sequence along the circumference of the second sleeve, and each second limiting groove is inserted with a second limiting protrusion, and each second limiting groove can respectively stop each second limiting protrusion in the circumferential direction of the second sleeve, so that the second sleeve can be subjected to uniform force.

[0020] In some implementations of the present application, the cover includes a cylinder and an end plate. The cylinder extends along a first direction, and the cylinder is sleeved outside the second sleeve and the buffer device. The end plate is arranged on the end surface of the cylinder along a second direction, and one end of the buffer device contacts the end plate, and the other end contacts the second sleeve.

[0021] In some implementations of the present application, a third limiting protrusion is provided on the inner wall of the cylinder, the third limiting protrusion is inserted into each second limiting groove, the third limiting protrusion can slide relative to the second limiting groove along the first direction or the second direction, and the side wall of the second limiting groove can block the third limiting protrusion from moving along the circumferential direction of the third sleeve. Exemplarily, the third sleeve is provided with a plurality of second limiting grooves arranged in sequence along the circumference of the third sleeve, the cylinder is provided with a plurality of third limiting protrusions arranged in sequence along the circumference of the cylinder, each second limiting groove is inserted with a third limiting protrusion, and each second limiting groove can respectively stop each third limiting protrusion along the circumference of the cylinder, so that the cylinder can be subjected to uniform force.

[0022] In some implementations of the present application, along the first direction, the second limiting protrusion is located between the buffer device and the third limiting protrusion. When the second sleeve moves along the first direction, the second sleeve pushes the cover body to move along the first direction through the buffer device; when the second sleeve moves along 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 to move along the second direction.

[0023] In a second aspect, the present application provides an electronic device, which includes 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.

[0024] In some implementations of the present application, the electronic device further includes a camera, and the cover cover of the cover assembly is disposed on the camera.

[0056] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] The 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 impacted by the outside world, the embodiment of the present application can reduce or avoid damage to the cover assembly.

[0058] In this application, the electronic device may be a mobile phone, a tablet, a computer, a PC camera, etc., which is not limited in this application. A mobile phone is used as an example of an electronic device for introduction below.

[0059] Figures 1 to 2B An exemplary structural diagram of an electronic device provided in an embodiment of the present application is shown. Figure 1 This is the appearance diagram of the electronic device. Figure 2A is a schematic diagram of the cover assembly in an extended state, Figure 2B It is a schematic diagram of the cover assembly in a retracted state.

[0060] refer to Figure 2A and Figure 2BThe 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 arranged outside the camera 200 and can be lifted and lowered with the camera 200 to protect the camera 200. For example, referring to Figure 2A When the camera 200 is extended to the outside of the housing 100, the cover 2 rises with the camera 200; Figure 2B When the camera 200 is retracted into the housing 100 , the cover 2 is lowered in coordination with the camera 200 .

[0061] 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 (recorded as the X1 direction, as the first direction), and the opposite direction is the negative direction of the X-axis (recorded 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 falling 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 / falling direction of the camera and the cover may also be other directions, for example, the length direction of the electronic device (such as Figure 1 (shown in the Y direction) etc.

[0062] When a user uses an electronic device, the electronic device often falls or bumps, etc. When the cover 2 extends to the outside of the housing 100, if the electronic device falls or bumps, the cover assembly 300 will be hit hard, which may cause damage to the cover assembly 300.

[0063] The present application provides a cover assembly, which is arranged on an electronic device. Figure 3 and Figure 4 The cover assembly includes: a base 1, a cover 2, a lifting device 3 and a buffer device 6. The cover 2 is arranged on one side of the base 1 along the X1 direction. The lifting device 3 is arranged on the base 1, and the lifting device 3 is used to drive the cover 2 to rise along the X1 direction or to 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 contacts the cover 2, and the other end contacts the driving end of the lifting device 3.

[0064] Figure 4 It is a schematic diagram of the structure when the cover body 2 rises to the top. Figure 5It is a schematic diagram of the structure when the cover 2 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 arranged 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 along the X1 direction, so that the cover 2 at least partially extends to the outside of the electronic device. In this process, the cover 2 may exert its gravity 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.

[0065] When the cover body 2 in the ascending state is subjected to an external force in the X2 direction, that is, when the cover body 2 is subjected to a force from outside the cover body assembly 300 (such as external pressure, impact force, etc.), the cover body 2 can retract in the X2 direction relative to the driving end of the lifting device 3. Figure 6 At this time, the buffer device 6 is squeezed and elastically deformed, providing a buffer for the retraction process of the cover body 2, thereby reducing the impact damage to the cover body 2 from the outside.

[0066] In some implementations of this application, reference Figure 7 and Figure 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. Exemplarily, 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 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.

[0067] In some implementations of this application, reference Figure 4 The lifting device 3 includes a fixed part 4 and a moving part 5. The fixed part 4 is arranged on the base 1. The moving part 5 is the driving end of the lifting device 3. The fixed part 4 can drive the moving part 5 to move along the X direction relative to the base 1 to drive the cover body 2 to extend and retract relative to the base 1.

[0068] 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.

[0069] In some implementations of this application, reference Figures 9 to 12The fixed part 4 includes a first sleeve 41, and the movable part 5 includes a second sleeve 51. The axis of the first sleeve 41 and the axis of the second sleeve 51 are both parallel to the X direction. The first sleeve 41 and the second sleeve 51 are mutually sleeved, and the buffer device 6 is arranged between the second sleeve 51 and the cover body 2. A slide groove 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 slide groove 42 and can slide along the slide groove 42. Among them, the slide groove 42 includes an inclined section 421, and the inclined section 421 is inclined relative to the first plane, and the first plane is a plane perpendicular to the X direction. When the first sleeve 41 rotates around its axis, the second sleeve 51 can be driven to move along the X direction through the inclined section 421 and the slider 52 to drive the movable part 5 to move.

[0070] In some implementations of this application, reference Fig. 9 and Fig.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 driving unit (not shown in the figure), the driving end of the driving unit is connected to the first sleeve 41, and the driving unit is used to drive the first sleeve 41 to rotate. Exemplarily, the driving unit can be a motor.

[0071] When the driving unit drives the first sleeve 41 to rotate, the inclined section 421 of the slide groove 42 rotates with the first sleeve 41. At this time, the inclined section 421 will apply a component force along the axial direction of the first sleeve 41 to the slider 52, so that the slider 52 and the second sleeve 51 connected to the slider 52 move along the X1 direction or the X2 direction to drive the cover 2 to expand and contract. 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 out of the electronic device along the X1 direction. 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 into the electronic device along the X2 direction. In some other implementations, when the X direction is a vertical direction, the gravity of the buffer device 6 and the cover body 2 both act on the second sleeve 51, so the two ends of the buffer device 6 can also be in contact with the cover body 2 and the second sleeve 51 respectively, and do not have to be connected to the cover body 2 and the second sleeve 51. When the second sleeve 51 moves along the X1 direction, the second sleeve 51 will lift the buffer device 6 and the cover body 2 above it and move together along the X1 direction. When the second sleeve 51 moves along the X2 direction, since the buffer device 6 and the cover body 2 are always pressed against the upper surface of the second sleeve 51 under the action of gravity, the buffer device 6 and the cover body 2 will move along the X2 direction with the second sleeve 51.

[0072] Compared with using a linear moving device such as an electric push rod to drive the cover body 2 to move, the present application uses a rotating first sleeve 41 and a moving part 5 sleeved with the first sleeve 41 to drive the cover body 2 to move, 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 easily causes uneven force on the cover body 2, resulting in jamming of the cover body 2 during movement, or causing the cover body 2 to be skewed when impacted by external force. The present application can make the cover body 2 run smoothly and prevent the cover body 2 from being skewed when impacted by external force by sleeve-mounting the first sleeve 41 and the second sleeve 51 with each other, and driving the second sleeve 51 to move by the rotating first sleeve 41.

[0073] In some implementations of this application, reference Fig. 9 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 the first horizontal section 422 is parallel to the first plane; the second horizontal section 423 is connected to the other end of the inclined section 421, and the second horizontal section 423 is parallel to the first plane. Exemplarily, the first horizontal section 422 is arranged at a side away from the base 1, and when the cover 2 rises to the top, the slider 52 slides into the first horizontal section 422; the second horizontal section 423 is arranged at a side close to the base 1, and when the cover 2 descends to the bottom, the slider 52 slides into the second horizontal section 423.

[0074] The present application sets the first horizontal section 422 and the second horizontal section 423 at both ends of the inclined section 421, respectively, so that when the cover body 2 rises to the top and falls to the bottom, the slider 52 can slide into the first horizontal section 422 and the second horizontal section 423 to achieve self-locking, so that the position of the cover body 2 when it rises to the top and falls to the bottom remains more stable. In addition, when a linear moving device such as an electric push rod is used to drive the moving part 5 to move, although a buffer device 6 is provided between the cover body 2 and the moving part 5, which can play a buffering role when the cover body 2 is hit by an external force, even so, the moving part 5 will still be subjected to a certain force in the X2 direction, and the moving part 5 will directly transmit the force to the electric push rod, which is easy to damage the electric push rod. The present application uses the rotating first sleeve 41 to drive the moving part 5 to move, so that when the cover body 2 rises to the top, the slider 52 can slide into the first horizontal section 422. If the cover body 2 is hit by an external force in the X2 direction at this time, the slider 52 on the moving part 5 will apply the external force to the first horizontal section 422. Since the extension direction of the first horizontal section 422 is perpendicular to the axial direction of the first sleeve 41, the slider 52 will not generate a component force 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, thereby avoiding damage to the drive unit (such as a motor) caused by the reverse rotation of the drive unit.

[0075] In some implementations of this application, reference Fig. 9 and Fig.10 The inner wall of the second sleeve 51 is provided with a plurality of sliders 52, and the sliders 52 are evenly arranged along the circumference of the second sleeve 51.
