Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to electronic equipment.

Background

With the explosive growth of electronic devices such as smart phones or tablet computers, the electronic devices are increasingly widely used. Speakers are typically provided in electronic devices. The speaker is a transducer device that can convert an electrical signal into an acoustic signal. The loudspeaker can be a moving-coil sounding monomer. The loudspeaker comprises a vibrating diaphragm, a front cavity and a rear cavity. The vibrating diaphragm can vibrate and sound. One side of the vibrating diaphragm is a corresponding front cavity, and the other side is a corresponding rear cavity. With the light and thin design of electronic devices and the requirement for high sound quality of speakers, speakers generally adopt an open-type sound cavity design, i.e., a rear cavity of the speaker is not a closed structure, but is in communication with an internal space of the electronic device. However, when the diaphragm of the speaker vibrates, the pressure of the internal space of the electronic device may change, resulting in a resonance phenomenon of the housing or the display screen of the electronic device. Under the condition that the user holds the electronic equipment by hands, the user can obviously feel the shock sensation, and the using experience satisfaction degree of the electronic equipment is affected.

Disclosure of Invention

The embodiment of the application provides electronic equipment, which can be beneficial to reducing the possibility of resonance of a covering piece caused by pressure change of an internal space of the electronic equipment.

The application provides an electronic device, which comprises a battery, a covering piece and a shock absorption component.

The covering piece is arranged on one side of the battery. The shock absorbing assembly includes a shock absorbing pad and a pressure control valve. At least a portion of the shock pad is disposed between the battery and the cover. The shock pad includes a first receiving chamber and a shock absorbing medium. The first accommodating cavity is internally provided with a damping medium. The pressure control valve is arranged on the shock pad. The pressure control valve is operable to be opened in response to the pressure in the first receiving chamber reaching a pressure threshold.

The electronic device comprises a battery, a covering piece and a shock absorption component. The shock pad in the shock absorbing assembly may be disposed between the battery and the cover of the battery. The cover may be attached to the middle frame. The battery may provide a supporting force for the shock pad, and the shock pad may provide a supporting force for the cover. Under the condition that a loudspeaker in the electronic equipment is in a working state, and the vibrating diaphragm vibrates, the shock pad can provide larger supporting force for the covering piece, so that the covering piece is not easy to vibrate when the pressure of the internal space of the electronic equipment changes. The mode of setting up the shock pad between battery and the covering of battery is favorable to reducing the pressure in the interior space of electronic equipment and takes place the change and lead to the possibility that the covering takes place resonance, improves the use experience satisfaction of electronic equipment.

In one possible embodiment, the side wall of the shock pad is provided with a pressure control valve.

The pressure control valve is operable to be opened in response to the pressure in the first receiving chamber reaching a pressure threshold. When the damping cushion is extruded to enable the pressure in the first accommodating cavity to be increased and reach the pressure threshold value, the pressure control valve can be opened, so that damping medium in the first accommodating cavity can be discharged through the pressure control valve, and pressure relief is achieved. The pressure control valve may close when the pressure within the first receiving chamber falls below a pressure threshold. Accordingly, the pressure of the first receiving chamber of the shock pad can be maintained relatively stable, so that the shock pad can maintain stability against the supporting force applied to the back cover.

In one possible embodiment, the pressure control valve is a one-way valve.

When the pressure in the first accommodating cavity reaches a preset pressure threshold value, the pressure control valve can be automatically opened to reduce the pressure of the first accommodating cavity. The pressure control valve may automatically close when the pressure in the first receiving chamber falls below a predetermined pressure threshold to maintain the current pressure in the first receiving chamber.

In one possible embodiment, the damping medium is a gas.

When the pressure in the first accommodating cavity reaches a preset pressure threshold value, the pressure control valve can be opened to release part of damping medium in the first accommodating cavity and reduce the pressure of the first accommodating cavity. Since the damping medium is gas, the damping medium can not pollute or corrode parts (such as a main board or an electronic device) in the electronic equipment after being discharged into the internal space of the electronic equipment.

In one possible embodiment, the first receiving cavity comprises a first chamber and a second chamber. More than two first chambers are arranged at intervals. The first chambers are communicated with each other through the second chamber.

The first holding cavity includes the setting mode of a plurality of first cavitys, is favorable to improving the bulk strength of shock pad for the condition that the shock pad is difficult for appearing local subsidence reduces the possibility that the shock pad leads to the supporting effect deviation of shock pad to the back of the body lid because of there is local subsidence in the shock pad. The first chambers are communicated with each other through the second chamber. In the process of filling the shock absorption medium into the shock absorption pad, the shock absorption medium can enter each first cavity through the second cavity, so that the operation of filling the shock absorption medium into each first cavity is not required, and the work efficiency is improved. In addition, as the first chambers and the second chambers are communicated, the positions of the pressure control valves can be flexibly selected, and meanwhile, the pressure relief function can be realized by only arranging one pressure control valve, and the pressure control valve does not need to be arranged corresponding to each first chamber.

In one possible embodiment, more than two first chambers are uniformly distributed, so that it is beneficial to ensure that the supporting force provided by the shock pad to the back cover is relatively balanced, and that the shock pad has a good supporting effect.

In one possible embodiment, at least one of the battery and the cover is connected to the shock pad, so that the shock pad in the electronic device after the assembly is completed can maintain its position relatively stable and is not easily biased.

In one possible embodiment, the material of the shock pad is plastic or rubber.

In one possible embodiment, the shock absorbing assembly further comprises an elastomeric expansion body. The elastic expansion body is provided with a second accommodating cavity. The shock pad is connected with the elastic expansion body, and the first accommodating cavity is communicated with the second accommodating cavity. The first accommodating cavity and the second accommodating cavity are internally provided with damping medium.

In the embodiment of the application, the shock pad is connected with the elastic expansion body. When the cover is pressed, the pressing force applied by the cover to the shock pad increases. The first receiving chamber of the shock pad is relatively reduced in volume and increased in pressure, but since the first receiving chamber and the second receiving chamber are communicated, the shock absorbing medium in the first receiving chamber can enter the second receiving chamber. After the pressure in the second accommodation cavity is increased, the elastic expansion body can expand, so that the pressure in the first accommodation cavity and the pressure in the second accommodation cavity can be stabilized, the pressure in the first accommodation cavity can not exceed a pressure threshold value, and the pressure control valve is prevented from being opened due to the fact that the covering piece is pressed by the outside. After the pressing force acting on the covering part disappears, the covering part can rebound to restore the initial state, the pressure in the first accommodating cavity of the shock pad is relatively reduced, at the moment, the elastic expansion body can shrink and deform, so that the shock absorption medium in the second accommodating cavity flows back into the first accommodating cavity, the pressure in the first accommodating cavity can be ensured to restore to the initial pressure, the pressure reduction of the shock pad to the covering part is effectively reduced, the supporting force of the shock pad to the covering part is reduced, and the possibility of influencing the vibration effect of the shock pad to the covering part is influenced.

In one possible embodiment, the electronic device further comprises a stop. The limiting piece is arranged on one side of the covering piece facing the battery. At least a portion of the resilient expansion body is disposed between the stop member and the cover member.

The limiting piece can play a constraint limiting role on the elastic expansion body, so that the expansion degree of the elastic expansion body can be controlled, the possibility that the elastic expansion body is overlarge in volume due to free expansion deformation of the elastic expansion body is reduced, and the possibility that extrusion is formed to other structural members in electronic equipment or the elastic expansion body is punctured by the other structural members due to overlarge volume of the elastic expansion body after the elastic expansion body is expanded is further reduced.

In one possible embodiment, the shock absorbing assembly further comprises a communication tube. The shock pad and the elastic expansion body are respectively connected with the communicating pipe. The first accommodating cavity is communicated with the second accommodating cavity through a communicating pipe.

The communicating tube itself can have smaller dimensions to the communicating tube can be disposed in a region where space is relatively narrow, so that the elastic expansion body can be selectively disposed in a region where space is relatively large and communicate with the shock pad through the communicating tube.

In one possible embodiment, the communication tube is of flexible construction.

The communicating pipe can be freely bent so as to be convenient for bypassing structural parts in the electronic equipment, and is beneficial to reducing the arrangement difficulty of the communicating pipe in the electronic equipment.

In one possible embodiment, the orthographic projection of the elastic expansion body is located outside the orthographic projection of the battery in the thickness direction of the battery. When the battery expands, the battery does not squeeze the elastic expansion body.

In one possible implementation manner, the elastic expansion body is connected with the covering piece, so that the elastic expansion body in the electronic equipment after assembly can keep the position of the elastic expansion body relatively stable, the elastic expansion body is not easy to deviate, and the possibility that other structural members puncture or scratch the elastic expansion body due to the deviation of the elastic expansion body in the deformation process is reduced.

In one possible implementation, the electronic device further includes a middle frame. The middle frame is provided with an accommodating space. The battery and the damping component are arranged in the accommodating space. The covering piece is connected with the middle frame.

In one possible embodiment, the cover is a back cover or a display screen.

The electronic device in the embodiment of the present application may be referred to as a User Equipment (UE) or a terminal (terminal), and the electronic device may be, for example, a tablet (portable android device, PAD), a personal digital assistant (personal digital assistant, PDA), a handheld device with a wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned (self driving), a wireless terminal in remote medical (remote media), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), or a mobile terminal or a fixed terminal. The form of the terminal device in the embodiment of the application is not particularly limited.

In an embodiment of the present application, fig. 1 schematically shows the structure of an electronic device 10. Referring to fig. 1, an electronic device 10 is illustrated as a handheld device having wireless communication capabilities. The handheld device of the wireless communication function may be a mobile phone, for example.

Fig. 2 schematically shows a partially exploded structure of the electronic device 10. Fig. 3 schematically shows a partially cut-away structure of the electronic device 10. Referring to fig. 1 to 3, an electronic apparatus 10 according to an embodiment of the present application includes a display 20, a housing 30, a main board 40, and an electronic device 50.

The display screen 20 has a display area for displaying image information. The display screen 20 is mounted to the housing 30, and a display area of the display screen 20 is exposed to facilitate presentation of image information to a user. Illustratively, the display screen 20 may include a light transmissive cover plate, a screen body, and a back plate. The light-transmitting cover plate is arranged on the light-emitting side of the screen body. The material of the light-transmitting cover plate can be glass or plastic. The screen body is used for displaying image information. The backboard is arranged on the backlight side of the screen body. The main board 40 is connected to the housing 30 and is located inside the display 20 so that the main board 40 is not easily observed by a user outside the electronic device 10.

The electronic device 50 is disposed on the motherboard 40. The motherboard 40 may be a printed circuit board (Printed Circuit Board, PCB). The electronic device 50 is soldered to the motherboard 40 by a soldering process. The electronic device 50 includes, but is not limited to, a central processing unit (Central Processing Unit, CPU), a smart algorithm chip, or a Power Management chip (PMIC). Because the internal space of the electronic device 10 is relatively small, the electronic device 50 is highly integrated on the motherboard 40, so as to fully reduce the volume of the motherboard 40 and reduce the space occupation rate of the motherboard 40.

Taking the electronic device 10 as an example including a display 20, the housing 30 includes a center 31 and a back cover 32. The display 20 is provided in the middle frame 31. The middle frame 31 has a housing space. The main board 40 may be disposed in the accommodating space. The back cover 32 is connected to the middle frame 31. The display screen 20 and the back cover 32 are respectively disposed on opposite sides of the middle frame 31. The middle frame 31 is located between the display screen 20 and the back cover 32 in the thickness direction of the electronic device 10.

The electronic device 10 also includes a battery 60. The back cover 32 is located on one side of the battery 60. The back cover 32 is a cover member that may cover the battery 60 on one side of the battery 60 to form a barrier to the battery 60. The back cover 32 may be visible outside the electronic device 10, but the battery 60 is not readily visible. The battery 60 is a structural member that can convert chemical energy into electrical energy. The battery 60 is used to provide power to the electronic device 10 to ensure proper operation of the electronic device 10. For example, the battery 60 may supply power to the display 20 to cause the display 20 to display image information or complete corresponding operation instructions, or the battery 60 may supply power to the main board 40 to ensure that the electronic device 50 on the main board 40 is operating normally. The battery 60 may be, for example, a lithium ion battery, such as a lithium iron phosphate battery. The battery 60 includes positive and negative tabs of opposite polarity. Illustratively, the battery 60 may be disposed within the receiving space of the center 31.

The electronic device 10 also includes a speaker 70. The speaker 70 is a transducer device that can convert an electrical signal into an acoustic signal. The speaker 70 may be a moving coil speaker 70 or a moving magnetic speaker 70, which is not particularly limited in the present application. The loudspeaker 70 includes a diaphragm 71, a front chamber disposed on one side of the diaphragm 71, and a rear chamber 72 disposed on the other side of the diaphragm 71. The housing 30 of the electronic device 10 may be provided with sound outlets. Illustratively, the sound outlet may be provided on a front cover or bezel 31 of the electronic device 10. The front cavity of the speaker 70 is disposed facing the sound outlet. The speaker 70 generates sound by vibrating the diaphragm 71. Sound waves generated by vibration of the diaphragm 71 may propagate through the front cavity and the sound outlet of the housing 30 to the outside of the electronic apparatus 10 to be listened to by the user.

The rear cavity 72 of the speaker 70 communicates with the interior space of the electronic device 10 such that the rear cavity 72 of the speaker 70 is of an open design. When the diaphragm 71 of the speaker 70 vibrates, the volume of the rear chamber 72 changes, and thus the pressure of the internal space of the electronic device 10 also changes, resulting in vibration of the back cover 32 as a cover. When the back cover 32 vibrates, on one hand, the connection stability of the components on the electronic device 10 is adversely affected; on the other hand, in the process of using the electronic device 10, the user may have a remarkable shock feeling of the electronic device 10, which affects the use experience of the electronic device 10.

In the electronic device 10 provided by the embodiment of the present application, the shock absorbing member 80 is provided between the battery 60 and the back cover 32 as a cover member. The shock-absorbing assembly 80 can support and buffer the back cover 32, which is beneficial to reducing the possibility of resonance of the back cover 32 as a covering part caused by pressure change of the internal space of the electronic device 10, and improving the use experience satisfaction of the electronic device 10.

The electronic device 10 of the present embodiment also includes a shock absorbing assembly 80. Illustratively, both the battery 60 and the shock assembly 80 may be disposed within the receiving space of the center 31. The shock absorbing assembly 80 of the present embodiment includes a shock pad 81. At least a portion of the shock pad 81 is disposed between the battery 60 and the back cover 32 as a cover member. The battery 60 and the back cover 32 are located on both sides of the shock pad 81, respectively, in the thickness direction Z of the battery 60. The thickness direction of the electronic device 10 is the same as the thickness direction Z of the battery 60. The shock pad 81 can provide a good supporting force for the back cover 32, so that when the internal space pressure of the electronic device 10 changes, the shock pad 81 can effectively inhibit the back cover 32 from vibrating, and reduce the shock feeling of the back cover 32. The shock pad 81 includes a first accommodating chamber 811 and a shock absorbing medium. The first housing chamber 811 has a damping medium therein.

Shock absorbing assembly 80 also includes a pressure control valve 82. The pressure control valve 82 is provided to the shock pad 81. The outlet of the pressure control valve 82 may be in communication with the interior space of the electronic device 10. The pressure control valve 82 is operable to be opened in response to the pressure in the first housing chamber 811 reaching a pressure threshold. When the shock pad 81 is compressed such that the pressure in the first accommodating chamber 811 increases and reaches the pressure threshold value, the pressure control valve 82 may be opened such that the shock-absorbing medium in the first accommodating chamber 811 may be discharged through the pressure control valve 82, thereby realizing pressure relief. When the pressure in the first housing chamber 811 falls below the pressure threshold, the pressure control valve 82 may be closed. Accordingly, the pressure of the first accommodating chamber 811 of the shock pad 81 can be maintained relatively stable, so that the shock pad 81 is maintained stable against the supporting force applied to the back cover 32.

The electronic device 10 of the present embodiment includes a battery 60, a cover, and a shock absorbing assembly 80. The shock pad 81 in the shock absorbing assembly 80 may be disposed between the battery 60 and the cover of the battery 60. The cover may be attached to the center 31. The battery 60 may provide a supporting force for the shock pad 81, and the shock pad 81 may provide a supporting force for the cover. In the case where the speaker 70 in the electronic apparatus 10 is in an operating state such that the diaphragm 71 vibrates, since the shock pad 81 can provide a large supporting force to the cover, the cover is also less prone to vibration when the pressure of the internal space of the electronic apparatus 10 changes. The manner of providing the shock pad 81 between the battery 60 and the cover of the battery 60 is beneficial to reducing the possibility of resonance of the cover caused by the pressure change of the internal space of the electronic device 10, and improving the use experience satisfaction of the electronic device 10.

In the related art, a damping foam may be provided between the battery 60 and the cover of the battery 60. The battery 60 and the cover of the battery 60 press the cushion foam against each other to provide a supporting force to the cover through the cushion foam, thereby being beneficial to buffering the vibration of the cover. However, there are situations where the battery 60 of the electronic device 10 swells during long-term use. If the supporting resilience force of the damping foam in the initial state is larger, that is, when the damping foam is pressed more flatly, after the battery 60 expands, the acting force of the damping foam on the covering member is increased, so that the damping foam jacks up the covering member, and the covering member is raised in a direction away from the battery 60. Therefore, the supporting resilience of the foam in the initial state generally needs to be reserved, so that after the battery 60 expands, the foam can be further extruded to reduce its thickness, so as to reduce the possibility that the foam will jack up the covering member after the battery 60 expands. However, since the supporting rebound force of the damping foam in the initial state needs to be reserved, the supporting force provided by the damping foam to the covering element is relatively small, so that the damping foam is not easy to sufficiently buffer the vibration of the covering element.

In the embodiment of the present application, a shock pad 81 in a shock absorbing assembly 80 is connected to a pressure control valve 82. The greater the pressure of the first accommodating chamber 811 of the shock pad 81, the greater the supporting force the shock pad 81 can provide to the cover. In the initial state, the pressure of the first receiving cavity 811 of the shock pad 81 may be maintained in a relatively large state, so that the shock pad 81 may provide a large supporting force to the cover to effectively buffer the shock of the cover. In the case where the battery 60 of the electronic device 10 swells during long-term use, the swelled battery 60 and the cover exert a larger pressing force on the shock pad 81, resulting in an increase in the pressure of the first accommodation chamber 811. When the pressure of the first accommodating chamber 811 of the shock pad 81 reaches a pressure threshold value, the pressure control valve 82 may be opened to depressurize the first accommodating chamber 811. When the pressure of the first accommodation chamber 811 of the shock pad 81 falls below the pressure threshold value, the pressure control valve 82 may be closed. Therefore, for the shock pad 81 in the initial state or the shock pad 81 after the expansion of the battery 60, the pressure of the first accommodating cavity 811 can be kept relatively stable, so that the shock pad 81 can keep stable to the supporting force acting on the cover, the shock pad 81 can be ensured to effectively buffer the shock of the cover, and meanwhile, the possibility that the shock pad 81 jacks up the cover after the expansion of the battery 60 can be effectively reduced.

The expansion of the battery 60 of the electronic device 10 is generally gradual during long-term use, and accordingly, the pressure control valve 82 may be intermittently opened to ensure that the pressure of the first housing cavity 811 remains relatively stable.

Shock pad 81 has side wall 812. The side wall 812 of shock pad 81 is provided with a pressure control valve 82. The side wall 812 of the shock pad 81 faces the inner space of the electronic device 10, so that the pressure control valve 82 is not likely to interfere with the position of other structural members.

In some examples, the front projection of the battery 60 may be located within the front projection of the shock pad 81 along the thickness direction Z of the battery 60. Illustratively, a portion of the shock pad 81 may extend beyond the battery 60.

In some examples, the front projection of the battery 60 may coincide with the front projection of the shock pad 81 along the thickness direction Z of the battery 60.

In some examples, the orthographic projection of the battery 60 may coincide with the orthographic projection portion of the shock pad 81 along the thickness direction Z of the battery 60. The pressure control valve 82 may be positioned between the back cover 32 and the battery 60 such that the pressure control valve 82 is not prone to collision or positional interference with structural members surrounding the battery 60, which is beneficial to reducing the likelihood of collision and damage to the pressure control valve 82 during assembly.

The pressure control valve 82 may be a one-way valve. When the pressure in the first housing chamber 811 reaches a predetermined pressure threshold, the pressure control valve 82 may be automatically opened to reduce the pressure in the first housing chamber 811. When the pressure in the first housing chamber 811 falls below a predetermined pressure threshold, the pressure control valve 82 may be automatically closed to maintain the current pressure in the first housing chamber 811.

Illustratively, the pressure control valve 82 may be a mechanical check valve. The pressure control valve 82 can be opened or closed according to the pressure change in the first accommodating cavity 811, so that a control unit for controlling the pressure control valve 82 to be opened or closed can be omitted, the number of parts is reduced, and the internal space of the electronic device 10 is saved.

Illustratively, fig. 4 schematically shows a partial structure of a shock absorbing assembly 80. Referring to fig. 4, the pressure control valve 82 includes a valve body 821 and a valve flap 822. A plurality of valve flaps 822 are disposed within the valve body 821. When the pressure in the first housing chamber 811 does not exceed the opening pressure threshold of the valve flaps 822, the plurality of valve flaps 822 are in a closed state. Fig. 5 schematically shows a partial structure of the shock absorbing assembly 80. Referring to fig. 5, when the pressure in the first accommodating chamber 811 exceeds the opening pressure threshold of the valve flaps 822, the plurality of valve flaps 822 are deformed to be in an open state. When the pressure in the first accommodation chamber 811 falls below the opening pressure threshold of the valve flaps 822, the plurality of valve flaps 822 are restored to the original state under the self elastic restoring force, and are in the closed state.

The damping medium in the damping pad 81 may be a gas. A predetermined amount of gas is filled in the first accommodating chamber 811 of the shock pad 81 so that the first accommodating chamber 811 maintains a predetermined pressure. In the case where the expansion of the battery 60 occurs, the battery 60 applies a pressing force to the shock pad 81, so that the volume of the first housing chamber 811 becomes smaller and the pressure in the first housing chamber 811 increases. When the pressure in the first housing chamber 811 reaches a predetermined pressure threshold, the pressure control valve 82 may be opened to release a portion of the damping medium in the first housing chamber 811 and reduce the pressure in the first housing chamber 811. Since the damping medium is a gas, the damping medium does not contaminate or corrode components in the electronic apparatus 10 (e.g., the motherboard 40 or the electronic device 50, etc.) after being discharged into the internal space of the electronic apparatus 10.

In some examples, the damping medium in the damping pad 81 may be air.

Fig. 6 schematically shows a partial structure of the electronic device 10. Fig. 7 schematically shows a partially cut-away structure of the shock pad 81. Fig. 8 schematically shows a partially cut-away structure of the electronic device 10. Referring to fig. 6, 7 and 8, the first receiving chamber 811 of the shock pad 81 may include a first chamber 811a and a second chamber 811b. More than two first chambers 811a are spaced apart. The first accommodating cavity 811 includes a plurality of first cavities 811a, which is beneficial to improving the overall strength of the shock pad 81, so that the shock pad 81 is not easy to partially collapse, and the possibility of deviation of the supporting effect of the shock pad 81 on the back cover 32 due to the partial collapse of the shock pad 81 is reduced. The respective first chambers 811a are communicated with each other through the second chamber 811b. In the process of filling the shock pad 81 with the shock absorbing medium, the shock absorbing medium may enter each of the first chambers 811a through the second chamber 811b, so that an operation of filling each of the first chambers 811a with the shock absorbing medium alone is not required, which is advantageous in improving work efficiency. In addition, since the first chamber 811a and the second chamber 811b are communicated, the position of the pressure control valve 82 can be flexibly selected, and the pressure release function can be achieved by providing only one pressure control valve 82, without providing a separate pressure control valve 82 for each first chamber 811 a.

In some examples, the areas of the shock pad 81 corresponding to the first and second chambers 811a and 811b may provide a supporting force to the back cover 32, and the areas of the shock pad 81 located between adjacent two of the first chambers 811a may have a space from the back cover 32 in the thickness direction Z of the battery 60.

In some examples, the number of the second chambers 811b may be one or more than two, which is not particularly limited in the present application.

In some examples, the first chamber 811a is bar-shaped. The respective first chambers 811a may be disposed parallel to each other. The second chamber 811b may be provided at an end portion of the first chamber 811a or may be provided at an intermediate region of the first chamber 811a in the longitudinal direction thereof, which is not particularly limited in the present application.

In some examples, more than two first chambers 811a may be uniformly distributed, so as to facilitate ensuring that the supporting force provided by the cushion 81 on the back cover 32 is relatively balanced, and ensuring that the cushion 81 has a good supporting effect. Illustratively, more than two first chambers 811a may be uniformly distributed in a determinant.

At least one of the battery 60 and the back case as a cover may be connected to the shock pad 81, so that the shock pad 81 in the electronic device 10 after completion of assembly may keep its position relatively stable and be less prone to be offset.

In some examples, the back shell is coupled to a shock pad 81. The shock pad 81 is filled with a predetermined amount of shock absorbing medium in advance. Then, the shock pad 81 having the shock absorbing medium is coupled with the back shell such that the shock pad 81 is fixed to a predetermined position of the back shell. The back shell and the middle frame 31 are connected, and after the assembly is completed, the back shell and the battery 60 can jointly extrude the shock pad 81. For example, the shock pad 81 may be adhered to the back shell. For example, the shock pad 81 is adhered to the back case using an adhesive or a double-sided adhesive tape.

For example, the back shell and the middle frame 31 may be separated when repair or inspection of the electronic device 10 is required. The back shell may be removed along with the shock pad 81. Because the shock pad 81 and the battery 60 are in the non-fixed connection state, in the process of removing the back shell, the condition that the battery 60 pulls the shock pad 81 does not exist, so that the condition that the shock pad 81 is torn or broken when the back shell is removed due to the fact that the battery 60 applies pulling force to the shock pad 81 is avoided, and the disassembly difficulty is reduced.

In some examples, battery 60 is coupled to shock pad 81. The shock pad 81 is filled with a predetermined amount of shock absorbing medium in advance. Then, the shock pad 81 having the shock absorbing medium is connected to the battery 60 such that the shock pad 81 is fixed to a predetermined position of the battery 60. The back shell and the middle frame 31 are connected, and after the assembly is completed, the back shell and the battery 60 can jointly extrude the shock pad 81. For example, the shock pad 81 may be adhered to the battery 60. For example, the shock pad 81 is adhered to the battery 60 using an adhesive or a double-sided adhesive tape.

For example, the back shell and the middle frame 31 may be separated when repair or inspection of the electronic device 10 is required. The back shell may be removed separately. Because be in the non-fixed connection state between shock pad 81 and the back shell, consequently in the in-process of removing the back shell, there is not the circumstances that the back shell was pulled shock pad 81 to avoid because of the back shell applys the tractive effort to shock pad 81 and when leading to removing the back shell, the shock pad 81 appears tearing or the circumstances of damage, is favorable to reducing the degree of difficulty of disassembling.

In some examples, the back shell and the battery 60 are both connected with the shock pad 81, which is beneficial to improving the connection strength among the back shell, the battery 60 and the shock pad 81, so that the back shell and the battery 60 can form constraint limit on the shock pad 81, and the possibility of position deviation of the shock pad 81 is reduced.

The shock pad 81 itself is a deformable structural member. When the shock pad 81 receives an external force, the shock pad 81 may be deformed so that the volume of the first receiving chamber 811 is reduced. After the external force is removed, the shock pad 81 may return to the original state so that the volume of the first receiving chamber 811 returns to the original state.

In some examples, the material of shock pad 81 may be plastic or rubber. Illustratively, the shock pad 81 may include two sheets disposed in a stacked arrangement. After the two sheets may be processed using the hot pressing process, the first and second chambers 811a and 811b may be formed on the shock pad 81.

Fig. 9 schematically shows a partially cut-away structure of the electronic device 10. Referring to fig. 9, shock absorbing assembly 80 further includes an elastomeric expansion body 83. The elastic expansion body 83 has a second accommodation chamber 831. The shock pad 81 is connected to the elastic expansion body 83, and the first housing chamber 811 is communicated with the second housing chamber 831. The first and second accommodation chambers 811 and 831 have a shock absorbing medium therein. The elastic expansion body 83 is a structural member having deformability. When the internal pressure of the elastic expansion body 83 increases, the elastic expansion body 83 may be expanded and deformed to increase the volume of the second receiving chamber 831. When the internal pressure of the elastic expansion body 83 is reduced, the elastic expansion body 83 may be contracted and deformed to reduce the volume of the second receiving chamber 831.

Since the cover member located on the side of the battery 60 is an exterior structural member, that is, the cover member is visible from the outside of the electronic apparatus 10, there is a possibility that the cover member is pressed from the outside during use of the electronic apparatus 10. When the cover is pressed, the cover is depressed in a direction approaching the battery 60, and the pressing force applied to the shock pad 81 by the cover is increased.

If the pressure in the first receiving cavity 811 of the shock pad 81 increases and the pressure control valve 82 is caused to open to release pressure because the cover is pressed, the cover itself may rebound to the original state after the pressing force acting on the cover is lost, but the pressure in the first receiving cavity 811 of the shock pad 81 is relatively reduced and cannot be restored to the original pressure, thereby causing the pressure of the shock pad 81 to the cover to decrease, the supporting force to the cover to affect the effect of the shock pad 81 to buffer the vibration of the cover.

In the embodiment of the present application, the shock pad 81 is connected to the elastic expansion body 83. When the cover is pressed, the pressing force applied by the cover to the shock pad 81 increases. The first receiving chamber 811 of the shock pad 81 is relatively reduced in volume and increased in pressure, but since the first receiving chamber 811 and the second receiving chamber 831 are communicated, the shock absorbing medium in the first receiving chamber 811 can be introduced into the second receiving chamber 831. After the pressure in the second accommodating chamber 831 increases, the elastic expansion body 83 expands, so that the pressures in the first accommodating chamber 811 and the second accommodating chamber 831 can be stabilized, so that the pressure in the first accommodating chamber 811 can not exceed the pressure threshold value, and the pressure control valve 82 can not be opened due to the external pressing of the cover. After the pressing force acting on the cover member disappears, the cover member itself may rebound to restore the original state, and the pressure in the first accommodating chamber 811 of the shock pad 81 is relatively reduced, at this time, the elastic expansion body 83 may contract and deform, so that the shock-absorbing medium in the second accommodating chamber 831 flows back into the first accommodating chamber 811, to ensure that the pressure in the first accommodating chamber 811 can restore to the original pressure, effectively reducing the pressure reduction of the shock pad 81 to the cover member, reducing the supporting force to the cover member, and affecting the possibility of the shock pad 81 to cushion the effect of the vibration of the cover member.

During the expansion of the battery 60, the battery 60 presses the shock pad 81 to reduce the volume of the first accommodating chamber 811 of the shock pad 81. The damping medium in the first receiving chamber 811 may enter the second receiving chamber 831 so that the pressure in the first receiving chamber 811 may not exceed a pressure threshold value and sufficient supporting force to the cover may be ensured. When the battery 60 expands to a predetermined degree, the elastic expansion body 83 itself expands and deforms to a predetermined degree, so that the pressure in the first housing chamber 811 and the second housing chamber 831 reaches the pressure threshold value, and the pressure control valve 82 can open the pressure release.

In some examples, fig. 10 schematically shows a partial cross-sectional structure of the electronic device 10. Referring to fig. 10, the electronic device 10 further includes a stopper 90. The stopper 90 is provided at a side of the cover facing the battery 60. At least a portion of the elastomeric expansion body 83 is disposed between the stop 90 and the cover. The limiting member 90 can perform a constraint limiting function on the elastic expansion body 83, so as to control the expansion degree of the elastic expansion body 83, and facilitate reducing the possibility of overlarge volume of the elastic expansion body 83 caused by free expansion deformation of the elastic expansion body 83, and further reduce the possibility of extrusion of other structural members in the electronic device 10 or puncture of the elastic expansion body 83 by other structural members due to overlarge volume of the elastic expansion body 83 after expansion.

For example, the elastic swelling body 83 may be integrally provided between the stopper 90 and the cover.

Illustratively, the stop 90 is removably attached to the back cover 32.

Illustratively, the stop 90 and the back cover 32 may be an integrally formed structure. During assembly, the resilient expansion body 83 may be fitted into the space formed between the stopper 90 and the back cover 32.

Illustratively, the material of the elastomeric body 83 may include, but is not limited to, rubber.

Illustratively, the battery 60 may be of rectangular configuration. At least one of opposite sides of the shock pad 81 may be provided with an elastic expansion body 83. Fig. 11 schematically shows a partial structure of the electronic device 10. Referring to fig. 11, an elastic swelling body 83 may be provided at one side of the shock pad 81 along the length direction Y of the battery 60. Alternatively, at least one of opposite sides of the shock pad 81 may be provided with an elastic expansion body 83. Fig. 12 schematically shows a partial structure of the electronic device 10. Referring to fig. 12, elastic swelling bodies 83 may be provided at opposite sides of the shock pad 81, respectively, in the width direction X of the battery 60.

Illustratively, the number of the elastic expansion bodies 83 may be one or two or more, which is not particularly limited in the present application.

The orthographic projection of the elastic swelling body 83 is located outside the orthographic projection of the battery 60 in the thickness direction Z of the battery 60. When the battery 60 expands, the battery 60 does not press the elastic expansion body 83.

The elastic expansion body 83 can be connected with the covering piece, so that the elastic expansion body 83 in the electronic device 10 after assembly can keep its own position relatively stable, and is not easy to deviate, and the possibility that other structural members puncture or scratch the elastic expansion body 83 due to the deviation of the elastic expansion body 83 in the deformation process is reduced.

In some examples, the cushion 81 and the elastic swelling body 83 may be pre-filled with a predetermined amount of the shock absorbing medium. Then, the cushion pad 81 and the elastic expansion body 83 having the shock absorbing medium are respectively connected to the cover such that the cushion pad 81 and the elastic expansion body 83 are respectively fixed to predetermined positions of the cover. After the cover is connected to the middle frame 31, the cover and the battery 60 can be co-extruded with the shock pad 81 after the assembly is completed. Illustratively, the elastomeric body 83 may be bonded to the cover. The elastic swelling body 83 is bonded to the cover using, for example, a bonding adhesive or a double-sided adhesive.

Shock assembly 80 also includes a communication tube 84. The shock pad 81 and the elastic swelling body 83 are connected to the communication pipe 84, respectively. The first receiving chamber 811 of the shock pad 81 is communicated with the second receiving chamber 831 of the elastic expansion body 83 through the communication pipe 84, so that the first receiving chamber 811 and the second receiving chamber 831 can achieve a flow of a shock absorbing medium through the communication pipe 84. The communication pipe 84 itself may have a small size, so that the communication pipe 84 may be disposed in a region where the space is narrow, so that the elastic expansion body 83 may be selectively disposed in a region where the space is large and communicate with the shock pad 81 through the communication pipe 84.

In some examples, one elastic expansion body 83 may be provided with one communication pipe 84 or more than two communication pipes 84, which is not particularly limited in the present application.

In some examples, the communication tube 84 is a flexible structure. The communication tube 84 may be freely bent so as to bypass structural members in the electronic apparatus 10, which is advantageous in reducing difficulty in arranging the communication tube 84 in the electronic apparatus 10. The material of the communication pipe 84 may be rubber, for example.

In some implementations, fig. 13 schematically shows a partial cross-sectional structure of the electronic device 10. Referring to fig. 13, the electronic device 10 may include two display screens 20. Both display screens 20 may be used to display image information. Along the thickness direction Z of the battery 60, two display screens 20 may be provided at intervals. The battery 60 is disposed between the two display screens 20. One display 20 is located on one side of the battery 60, and the other display 20 is spaced from the battery 60 by a center 31. The main difference with the embodiment in which the cover is a back cover 32 is that the cover may be a display screen 20 located on one side of the battery 60. In the related art, when the diaphragm 71 of the speaker 70 vibrates, the display screen 20 as a cover vibrates. When the display screen 20 vibrates, on one hand, adverse effects are caused on the connection stability of the components on the electronic device 10; on the other hand, in the process of using the electronic device 10, the user may have a remarkable shock feeling of the electronic device 10, which affects the use experience of the electronic device 10. The shock pad 81 in the shock absorbing assembly 80 of the embodiment of the present application may be disposed between the display screen 20 and the battery 60 as a cover. The shock pad 81 can provide a good supporting force for the display screen 20 as the cover, so that when there is a shock condition of the display screen 20 as the cover, the shock pad 81 can effectively suppress the shock of the display screen 20 as the cover, reducing the shock feeling of the display screen 20 as the cover.
