Description

An electronic device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on January 31, 2024, with application number 202410155259.7 and invention name “An Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of laptop computers, and more particularly to an electronic device. Background Art

[0003] A notebook computer is also known as a "portable computer, handheld computer, PDA or laptop computer". Its biggest feature is its compact body. The display screen and body can be folded. Compared with a PC, it is more convenient to carry. It is a small and portable personal computer.

[0004] A laptop typically consists of a display side and a main unit, mechanically connected by a hinge mechanism. The display side's housing rotates relative to the main unit around the hinge's pivot axis, allowing the laptop to be opened and closed. To transmit electrical signals between the display and system sides, the electronic components in the two sides can be electrically connected using a flexible printed circuit (FPC).

[0005] During laptop opening and closing, the display side frequently needs to be extended or closed relative to the main unit, so the flexible cable is typically set to a certain length. During expansion, the display side often pulls the flexible cable out of the main unit, but during closing, it becomes difficult to retract the extended flexible cable back into the main unit. Due to this change in length, the flexible cable extending from the system side can easily arch during opening and closing, potentially causing severe compression and breakage. Summary of the Invention

[0006] An embodiment of the present application provides an electronic device for solving the problem that, during the opening and closing process of a laptop-type electronic device, the connection cable between the display side and the host side cannot be effectively retracted after being pulled out, causing the connection cable to deform during the long-term opening and closing process, thereby affecting its use quality.

[0007] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, the present application provides an electronic device, which includes a first part, a second part, and a flexible cable. The first part and the second part are rotatably connected by a rotating shaft, so that the electronic device can be expanded or closed. The first part generally refers to the display side of the electronic device, and the second part generally refers to the host side of the electronic device. The first part and the second part are also electrically connected by a flexible cable. The second part also includes an elastic bracket, and the flexible cable is wound around the elastic bracket. The elastic bracket is elastic, and when the flexible cable is wound around the elastic bracket, the flexible cable can cause the elastic bracket to deform when pulled.

[0009] When the electronic device is in the process of unfolding, the first part drives the flexible cable to move from the second part to the first part, and the flexible cable drives the elastic bracket to deform. When the electronic device is in the process of closing, the elastic bracket recovers its deformation and retracts the extended flexible cable into the second part. In this technical solution, the electronic device will directly pull the flexible cable to move outward from the second part during the opening and closing process, but cannot push the flexible cable to move inward from the second part. By providing an elastic bracket, the flexible cable drives the elastic bracket to deform when it moves outward during the opening process, and during the closing process, the elastic bracket recovers its deformation to provide elastic force for the flexible cable, pulling it back into the second part. This ensures that the flexible cable can be retracted after being pulled out during the opening and closing process, preventing the flexible cable from having quality problems such as folding and arching during the process, thereby increasing its service life.

[0010] In one possible implementation of the first aspect, the elastic bracket includes a bracket body, a compression piece, and an elastic assembly. The elastic assembly includes a crossbeam, a first connector, and a second connector. The crossbeam is fixedly connected to the bracket body at both ends via the first connector and the second connector. The bracket body is fixedly connected to the second portion. The flexible cable is compressed against the bracket body via the compression piece, and the flexible cable is wound around the crossbeam.

[0011] In this implementation, a compression plate secures one end of the flexible cable, allowing the flexible cable to be pulled, causing the elastic component to deform. The elastic component primarily provides elastic force for the flexible cable. By wrapping the flexible cable around a beam, the flexible cable can drive the beam to move, thereby causing the elastic component to deform. Furthermore, the beam can drive the flexible cable to move, thereby pulling the flexible cable back. In other words, wrapping the flexible cable around a beam allows the flexible cable to move relative to the beam, while also enabling the flexible cable and beam to move together in the same direction.

[0012] In one possible implementation of the first aspect, both the first connector and the second connector are elastic. When the electronic device is extended, the flexible cable is pulled out of the second portion, causing the flexible cable to move the crossbeam, which in turn causes the first and second connectors to deform. When the electronic device is closed, the first and second connectors recover their deformation, causing the crossbeam to move, and the crossbeam retracts the extended flexible cable into the second portion.

[0013] In this implementation, a specific form of providing elastic force for the elastic bracket is provided, that is, deformation is generated by the first connecting member and the second connecting member, and the process of restoring the deformation provides tension for the flexible cable.

[0014] In a possible implementation of the first aspect, the crossbeam includes a first support beam and a second support beam, the first support beam and the second support beam are in contact with each other, the first support beam is a rigid beam, and the second support beam is a flexible beam. When the flexible cable is wound around the crossbeam, the flexible cable contacts the second support beam.

[0015] In this implementation, the first beam is configured as a rigid beam to provide a certain degree of strength for the crossbeam, keeping it straight and preventing deformation that could cause excessive localized stress on the flexible cable. The second beam is placed in contact with the flexible cable, achieving soft contact between the cable and the beam, preventing damage to the flexible cable caused by long-term friction.

[0016] In a possible implementation of the first aspect, the structure of the first connecting member is the same as that of the second connecting member. The first connecting member includes a first crossbar, a first vertical bar, and a second crossbar. The first vertical bar is connected to the first crossbar and the second crossbar at both ends, the first crossbar is connected to the bracket body, and the second crossbar is connected to the crossbeam. The first vertical bar is perpendicular to the first crossbar and the second crossbar, and the first crossbar is also perpendicular to the second crossbar.

[0017] In this implementation, a specific structural design of the first connecting member and the second connecting member is provided. Through different structural designs, the first connecting member can generate deformation and recover deformation better.

[0018] In a possible implementation manner of the first aspect, the first connecting member and the second connecting member are both made of silicone.

[0019] In one possible implementation of the first aspect, the elastic assembly further includes an elastic member disposed on one side of the crossbeam. When the flexible cable is wrapped around the crossbeam, the flexible cable contacts the elastic member. When the electronic device is deployed, the flexible cable is pulled out of the second portion, squeezing the elastic member and deforming the elastic member. When the electronic device is closed, the elastic member recovers its deformation, retracting the extended flexible cable back into the second portion.

[0020] In this implementation, another implementation of the elastic bracket is provided, that is, by providing an elastic member, the flexible cable is squeezed by the elastic member to cause deformation when being pulled out, and the flexible cable is retracted by the elastic member recovering the deformation.

[0021] In a possible implementation of the first aspect, the elastic member is made of foam.

[0022] In one possible implementation of the first aspect, the flexible cable is routed in an S-shaped pattern on the elastic bracket, and the flexible cable contacts the bracket body and the crossbeam, respectively. The surface where the bracket body contacts the flexible cable is a first contact surface, and the surface where the crossbeam contacts the flexible cable is a second contact surface. The first and second contact surfaces are arc surfaces or elliptical surfaces, and the central angles of the first and second contact surfaces are both less than 90°.

[0023] In this implementation, the flexible cable is routed in an "S" shape on the elastic bracket. This is primarily to facilitate securing the flexible cable and enable the flexible cable to deform the elastic component or elastic member on the elastic bracket, thereby retracting the flexible cable through the elastic bracket. Alternatively, the flexible cable can be routed in other shapes on the elastic bracket, such as a "Z" or "U" shape, as long as the elastic component or elastic member on the elastic bracket can be deformed.

[0024] In one possible implementation of the first aspect, the elastic bracket includes a bracket body, an elastic member, and a compression piece. The bracket body is fixedly connected to the second portion, and the elastic member is fixedly connected to the bracket body. A flexible cable is wound around the elastic member, and one end of the flexible cable is compressed against the second portion by the compression piece.

[0025] In this implementation, another specific shape of the elastic bracket is shown, wherein the elastic member can be made of foam.

[0026] In one possible implementation of the first aspect, the flexible cable is routed in a U-shape on the elastic bracket, and the flexible cable contacts the elastic member. The surfaces where the elastic member and the flexible cable contact each other include a first contact surface and a second contact surface. The first contact surface and the second contact surface are arc surfaces or elliptical surfaces, and the central angles corresponding to the first contact surface and the second contact surface are both less than 90°.

[0027] In this implementation, a flexible cable is wound around an elastic support to form a U-shaped arrangement. By pulling the flexible cable, the elastic member within the U-shaped arrangement is deformed. When the elastic member returns to its original shape, the pulled flexible cable can be retracted, thus achieving the function of retracting the flexible cable. After the flexible cable is wound around the elastic support, the flexible cable will bend at least two locations, and the locations where the flexible cable bends form contact surfaces with the elastic support. The entire flexible cable has at least two of these contact surfaces between it and the elastic member. The contact surfaces on the elastic support should be as smooth as possible to prevent the flexible cable from bending too much. Therefore, the first and second contact surfaces are arc-shaped or elliptical surfaces, and the central angles corresponding to the first and second contact surfaces are both set to be less than 90°. This is to ensure that the first and second contact surfaces are as smooth as possible. Of course, the first and second contact surfaces can also be configured as arc-shaped surfaces of other shapes, and the first and second contact surfaces can be configured to be as smooth as possible so that the bending angle of the flexible cable at these contact surfaces is greater than 90°.

[0028] In a possible implementation of the first aspect, the first part further includes a rotation shaft cover, and the rotation shaft cover rotates relative to the second part along with the first part. The flexible cable passes through the rotation shaft cover.

[0029] This implementation provides a specific method for connecting the first and second parts with a flexible cable. Specifically, the flexible cable passes through the first part, then through the hinge cover and into the second part. Of course, other methods are also possible. For example, the flexible cable passes through the first part, then wraps around the hinge cover and is secured to it before entering the second part.

[0030] In a possible implementation of the first aspect, a cable blocking cloth is provided on one side of the flexible cable, and when the electronic device is unfolded or closed, the cable blocking cloth blocks the flexible cable from view.

[0031] In this implementation, by placing the cable blocking cloth on one side of the flexible cable, when the electronic device is unfolded or closed, the cable blocking cloth blocks the flexible cable from view, preventing the flexible cable at the connection between the first part and the second part from being directly exposed to the view, which would affect the aesthetics of the electronic device. At the same time, it protects the flexible cable from contact with external sharp objects, preventing sharp objects from damaging the flexible cable.

[0032] In a possible implementation of the first aspect, a fixing post is provided on the flexible bracket, one end of the wire blocking cloth is fixedly connected to the fixing post, and the other end of the wire blocking cloth is connected to the shaft cover via a clamping device.

[0033] In a possible implementation of the first aspect, the wire blocking cloth is attached to the flexible cable and moves along with the flexible cable. One end of the wire blocking cloth is fixedly connected to the elastic bracket, and the other end of the wire blocking cloth is connected to the shaft cover through a clamping device.

[0034] In this implementation, a specific connection relationship between the wire blocking cloth and the flexible cable is provided, that is, the wire blocking cloth is arranged to be attached to the flexible cable, which can improve the aesthetics of the electronic device while protecting the flexible cable.

[0035] In a possible implementation manner of the first aspect, a rotation angle of the first part and the second part is 0° to 180°.

[0036] In this implementation, by setting the rotation angle of the first part and the second part to 0° to 180°, it can be set to a suitable angle as needed to meet different needs of users. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The present application provides an electronic device, which may be a laptop computer, a notebook computer, or other similar portable computing devices. The embodiments of the present application are described using the notebook computer as an example.

[0076] Referring to Figure 1A, Figure 1A is a schematic diagram of the overall structure of an electronic device provided in an embodiment of the present application. As shown in Figure 1A, the electronic device 100 includes a first part 110 on the display side and a second part 120 on the host side, wherein the first part 110 includes a first shell 111, and a display screen 112 arranged in the first shell 111. The second part 120 includes a second shell 121, a keyboard and a touch panel arranged on the upper side of the second shell 121, and various electronic components arranged inside the second shell 121, such as a motherboard, a processor, a memory, a speaker, etc. The first part 110 and the second part 120 are connected together by a rotating component such as a rotating shaft or a hinge, so that the first part 110 and the second part 120 can achieve relative rotation, so that the laptop computer can be opened or closed.

[0077] The hinge of a laptop computer is typically located at either end of the connection between the first and second housings 111, 121. For aesthetic reasons, a hinge cover 130 is typically positioned outside the hinge, with the hinge positioned within the hinge cover 130. The hinge occupies a portion of the space within the hinge cover 130, leaving the remaining space for wiring or other design options. In the embodiment of the present application, the hinge cover 130 is connected to the first portion 110, meaning that the hinge cover 130 can be positioned at the connection between the first and second housings 111, 121. When the first portion 110 rotates relative to the second portion 120, the hinge cover 130 also rotates relative to the second portion 120.

[0078] In the embodiment of the present application, when the first portion 110 and the second portion 120 rotate relative to each other, the rotation angle between the first portion 110 and the second portion 120 can be between 0° and 180°. When the angle between the first portion 110 and the second portion 120 is 0°, the first portion 110 is attached to the second portion 120, and the electronic device 100 is considered to be in a closed state. When the angle between the first portion 110 and the second portion 120 is 180°, the first portion 110 and the second portion 120 are substantially in the same plane, and the electronic device 100 is considered to be in an extended state. Generally, the closed and extended states of the electronic device 100 refer to the first portion 110 and the second portion 120 being within a certain angular range. For example, when the angle between the first portion 110 and the second portion 120 is between 0° and 45°, the electronic device 100 is considered to be in a closed state; when the angle between the first portion 110 and the second portion 120 is between 45° and 180°, the electronic device 100 is considered to be in an extended state. It should be noted that the expansion process and closing process of the electronic device 100 refer to a dynamic process. The process in which the angle between the first part 110 and the second part 120 becomes larger can be called the expansion process, and the process in which the angle between the first part 110 and the second part 120 becomes smaller can be called the closing process.

[0079] In some electronic devices, data transmission is required between the first portion 110 and the second portion 120 of the electronic device. For example, after data is processed on the host side of a laptop computer, it needs to be transmitted to the display screen 112 in the first portion 110 on the display side for display. Therefore, an electrical connection is required between the first portion 110 and the second portion 120. As shown in FIG1A , a flexible cable 140 is provided between the first portion 110 and the second portion 120. One end of the flexible cable 140 can enter the first portion 110 from a middle position on the side of the first portion 110 near the second portion 120. The other end of the flexible cable 140 can enter the second portion 120 from a middle position on the side of the second portion 120 near the first portion 110.

[0080] In addition, reference may also be made to FIG1B , which is an exploded view of an electronic device provided in an embodiment of the present application. FIG1B mainly shows the approximate position where the flexible cable 140 is connected to the first part 110 and the second part 120. As shown in FIG1B , a connection hole may be provided on the first part 110 and a connection hole may be provided on the second part 120 in the middle position on one side where the first part 110 and the second part 120 are connected to each other, and one end of the flexible cable 140 is passed through the connection hole on the first part 110 into the first part 110, and the other end of the flexible cable 140 is passed through the connection hole on the second part 120 into the second part 120.

[0081] In an embodiment of the present application, the first part 110 includes a first electronic component, the second part 120 includes a second electronic component 122, and the first electronic component and the second electronic component 122 are electrically connected via a flexible cable 140. Referring to Figures 2, 3 and 4, Figure 2 is a three-dimensional structural schematic diagram of a local structure of an electronic device provided in an embodiment of the present application, Figure 3 is a partial cross-sectional view of an electronic device provided in an embodiment of the present application, and Figure 4 is another partial cross-sectional view of an electronic device provided in an embodiment of the present application. Figure 2 is a three-dimensional structural schematic diagram of the first part 110 and the second part 120 in the electronic device in a closed state. Figure 2 mainly shows the connection relationship between the flexible cable 140 and the first part 110 and the second part 120 in the electronic device, the approximate position of the elastic bracket 150, and the connection relationship and routing shape between the flexible cable 140 and the elastic bracket 150. Figures 3 and 4 can both be cross-sectional views obtained after cutting along the dotted line in Figure 1A and perpendicular to the direction of the display screen. The difference between Figures 3 and 4 is that the electronic device in Figure 3 is in a closed state, at which point the angle between the first portion 110 and the second portion 120 is approximately 0°. The electronic device in Figure 4 is in an unfolded state, at which point the angle between the first portion 110 and the second portion 120 is approximately 150°.

[0082] As shown in Figures 2, 3 and 4, the hinge cover 130 is fixedly connected to the first shell 111 of the first part 110, and openings are provided on the connection side of the first shell 111 and the connection side of the hinge cover 130 and the second shell 121, so that one end of the flexible cable 140 can enter the first shell 111 through the opening on the first shell 111 and be electrically connected to the first electronic component (not shown in Figures 3 and 4), and the other end of the flexible cable 140 passes through the hinge cover 130, enters the second shell 121 from the through hole 161 on the second shell 121, and is electrically connected to the second electronic component 122 (not shown in Figure 4).

[0083] In the embodiment of the present application, the flexible cable 140 needs to pass through the hinge cover 130 to connect the first electronic component in the first part 110 and the second electronic component 122 in the second part 120. Since the hinge cover 130 rotates with the first part 110, in order to reduce the pulling of the flexible cable 140 during the rotation of the hinge cover 130, the flexible cable 140 preferably passes through the axis of the hinge cover 130 when passing through the hinge cover 130. This can reduce the length of the flexible cable 140 within the hinge cover 130 and reduce the length of the flexible cable 140 pulled during the rotation of the hinge cover 130. In actual applications, it is difficult to pass the flexible cable 140 through the axis of the hinge cover 130. There may be a certain deviation between the actual exit position and the axis, for example, the deviation from the axis is about 1 mm.

[0084] It should be noted that in the embodiment of the present application, as shown in FIG3 , due to the shape of the hinge cover 130, when the angle between the first portion 110 and the second portion 120 is 0°, the hinge cover 130 does not contact the flexible cable 140. When the first portion 110 rotates relative to the second portion 120 by a certain angle, the hinge cover 130 begins to contact the flexible cable 140. This angle can be referred to as a threshold angle. When the first portion 110 continues to rotate relative to the second portion 120 after reaching the threshold angle, the hinge cover 130 will pull the flexible cable 140 out of the second portion 120. The threshold angle in FIG3 is approximately 120°. That is, in the electronic device shown in FIG3 , when the first portion 110 rotates relative to the second portion 120 by an angle greater than 120°, the hinge cover 130 will pull the flexible cable 140 out of the second portion 120. In FIG4 , the first portion 110 is rotated relative to the second portion 120 by approximately 150°. It can be seen that the hinge cover 130 is in contact with the flexible cable 140 and pulls the flexible cable 140 out of the second portion 120. The scenario in which the first portion 110 rotates relative to the second portion 120 and the flexible cable 140 is pulled out of the second portion 120 in the embodiments of the present application, for example, refers to the relative rotation between the first portion 110 and the second portion 120 when the included rotation angle between the first portion 110 and the second portion 120 is in the range of 120° to 180°.

[0085] In another embodiment of the present application, referring to Figures 5 and 6, Figure 5 is a partial cross-sectional view of another electronic device provided in an embodiment of the present application, and Figure 6 is another partial cross-sectional view of another electronic device provided in an embodiment of the present application. Figures 5 and 6 can both be cross-sectional views obtained by cutting along the dotted line in Figure 1A and perpendicular to the direction of the display screen. The electronic device in Figure 5 is in a closed state, at which time the angle between the first part 110 and the second part 120 is approximately 0°. The electronic device in Figure 6 is in an expanded state, at which time the angle between the first part 110 and the second part 120 is approximately 150°.

[0086] As shown in Figures 5 and 6, the hinge cover 130 is fixedly connected to the first housing 111 of the first portion 110. Openings are provided on both the connection side of the first housing 111 and the connection side of the second housing 121. One end of the flexible cable 140 enters the first housing 111 through the opening in the first housing 111 to be electrically connected to the first electronic device, and the other end enters the second housing 121 through the opening in the second housing 121 to be electrically connected to the second electronic device. In this embodiment of the present application, the flexible cable 140 does not pass through the hinge cover 130, but instead passes through the opening in the first housing 111 and is fixedly connected to the hinge cover 130.

[0087] In the electronic device shown in Figures 5 and 6 , because the flexible cable 140 is fixedly connected to the hinge cover 130, the threshold angle for the rotation of the first portion 110 and the second portion 120 is 0°. That is, when the first portion 110 and the second portion 120 rotate relative to each other from an angle of 0°, the hinge cover 130 pulls the flexible cable 140 out of the second portion 120. In other words, the technical solutions described in the embodiments of this application can also be applied to scenarios where the rotation angle between the first portion 110 and the second portion 120 changes from 0° to 180°.

[0088] As can be seen from the change from Figure 5 to Figure 6 , as the electronic device is unfolded, the flexible cable 140 in the second portion 120 is pulled out, and the elastic bracket 150 disposed in the second portion 120 of the electronic device is compressed, causing deformation. Conversely, as can be seen from the change from Figure 6 to Figure 5 , as the electronic device is closed, there is no external force pulling on the flexible cable 140 in the second portion 120, and the elastic bracket 150 recovers its deformation, pulling the pulled flexible cable 140 back into the second portion 120. It should be noted that the elastic bracket 150 in Figure 5 and the elastic bracket 150 in Figure 3 have certain structural differences, but their functions are the same.

[0089] To ensure smooth opening and closing of the electronic device, the flexible cable 140 is typically long, keeping it loose and flexible. During the unfolding process, the electronic device pulls a portion of the flexible cable 140 out of the second portion 120. If the extended portion of the flexible cable 140 cannot be retracted back into the second portion 120 during the closing process, the extended flexible cable 140 can easily arch during the opening and closing process due to the change in length, potentially causing severe compression and breakage of the flexible cable 140, leading to failure.

[0090] It should be noted that the flexible cable 140 can be any suitable type of cable, including a flexible cable, a flexible printed circuit board, or any suitable mechanism for transmitting electrical signals between the first electronic component and the second electronic component 122. In some embodiments, the flexible cable 140 is a ribbon-shaped single-layer flexible cable. Of course, a multi-layer flexible cable can also be used. A single-layer flexible cable can be used to reduce the stack height (i.e., vertical thickness) of the flexible cable 140. In some embodiments, the flexible cable 140 can also be a flexible printed circuit board.

[0091] In order to avoid the situation where the flexible cable 140 is pulled out of the second part 120 but cannot be retracted during the opening and closing process of the electronic device. In an embodiment of the present application, refer to Figure 7, which is a schematic diagram of the connection structure between the elastic bracket and the second part of an electronic device provided in an embodiment of the present application. As shown in Figure 7, an elastic bracket 150 is provided in the second part 120 of the electronic device, wherein the elastic bracket 150 is fixedly connected to the second shell 121 of the second part 120. The elastic bracket 150 can be connected to the second shell 121 of the second part 120 by gluing or screwing. In an embodiment of the present application, as shown in Figure 7, the two ends of the elastic bracket 150 are respectively fixed to the second shell 121 by screws. The flexible cable 140 is wound around the elastic bracket 150.

[0092] As can be seen from the changes from Figure 3 to Figure 4, when the electronic device is unfolded, the angle between the first part 110 and the second part 120 increases, and the hinge cover 130 on the first part 110 rotates with the first part 110. After the hinge cover 130 contacts the flexible cable 140, the flexible cable 140 is pulled out from the second part 120 to the first part 110. Since the flexible cable 140 is wound around the elastic bracket 150, the flexible cable 140 can drive the elastic bracket 150 to deform.

[0093] As can be seen from the changes in Figure 4 to Figure 3, when the electronic device is in the closing process, the angle between the first part 110 and the second part 120 becomes smaller, and the hinge cover 130 on the first part 110 no longer generates an outward pulling force on the flexible cable 140. At this time, the elastic bracket 150 recovers its deformation, driving the flexible cable 140 wound around the elastic bracket 150 to move toward the inside of the second part 120, and retracting the extended flexible cable 140 into the second part 120.

[0094] It should be noted that in the embodiment of the present application, the flexible cable 140 being wound around the elastic bracket 150 means that the flexible cable 140 forms at least one bending area within the second portion 120, and the elastic bracket 150 is located within the bending area. When one end of the flexible cable 140 within the second portion 120 is fixed, when the other end of the flexible cable 140 is pulled, the bending area of ​​the flexible cable 140 in contact with the elastic portion of the elastic bracket 150 will move in the direction of the force, thereby causing (the elastic portion of) the elastic bracket 150 to deform.

[0095] In one embodiment of the present application, the elastic bracket 150 can be seen in Figures 8 and 9 . Figure 8 is a schematic structural diagram of an elastic bracket 150 in an electronic device provided in an embodiment of the present application, and Figure 9 is an exploded view of an elastic bracket 150 in an electronic device provided in an embodiment of the present application. As shown in Figures 8 and 9 , the elastic bracket 150 includes a bracket body 160, a compression plate 170, and an elastic assembly 180. The compression plate 170 is connected to one side of the bracket body 160, and the elastic assembly 180 is connected to the other side of the bracket body 160. The compression plate 170 is primarily used to secure the flexible cable 140 to the bracket body 160. The elastic assembly 180 can deform relative to the bracket body 160 to provide retraction force for the pulled flexible cable 140. The compression plate 170 and the elastic assembly 180 are respectively arranged on either side of the elastic bracket 150 to facilitate winding the flexible cable 140 around the elastic bracket 150.

[0096] Since the elastic bracket 150 is fixedly connected to the second portion 120, in the embodiment of the present application, the bracket body 160 can be fixedly connected to the second housing 121 on the second portion 120. Specifically, through holes 161 can be provided at both ends of the bracket body 160, and then the bracket body 160 can be fixed to the second housing 121 of the second portion 120 using screws. For example, the bracket body 160 can be fixed to the side of the second housing 121 where the keyboard is provided (also known as the C-shell of a laptop computer) using screws. Of course, other fixing methods can also be used, and the embodiment of the present application does not limit the specific fixing method of the elastic bracket 150.

[0097] In addition, as shown in FIG9 , a fixing column 162 may be provided on the back of the bracket body 160 . When a wire blocking cloth 190 is required in the electronic device, the wire blocking cloth 190 may be fixedly connected to the fixing column 162 on the back of the bracket body 160 .

[0098] As shown in Figures 8 and 9, the elastic assembly 180 includes a crossbeam 183, a first connecting member 181, and a second connecting member 182. The ends of the crossbeam 183 are fixedly connected to the bracket body 160 via the first connecting member 181 and the second connecting member 182, so that a certain gap is formed between the crossbeam 183 and the bracket body 160.

[0099] In one embodiment of the present application, as shown in Figure 9, the crossbeam 183, the first connecting member 181 and the second connecting member 182 can be formed as one piece, and a connecting head is provided at the other end of the first connecting member 181 and the second connecting member 182, and connecting holes or connecting grooves corresponding to the connecting heads can be provided at both ends of the bracket body 160 (not shown in the figure) to achieve a fixed connection between the first connecting member 181 and the bracket body 160, and to achieve a fixed connection between the second connecting member 182 and the bracket body 160.

[0100] When the flexible cable 140 is wound around the elastic bracket 150, the first end of the flexible cable 140 is passed through the gap between the compression piece 170 and the bracket body 160, and the first end is electrically connected to the second electronic component 122 in the second portion 120. The compression piece 170 is then tightened, and the flexible cable 140 is fixed to the bracket body 160 via the compression piece 170. Alternatively, the flexible cable 140 is placed on the side of the bracket body 160 where the compression piece 170 is provided, and then the compression piece 170 is placed on the flexible cable 140 so that the flexible cable 140 is located between the compression piece 170 and the bracket body 160. The compression piece 170 is then fixed to the bracket body 160 so that the flexible cable 140 is fixed between the compression piece 170 and the bracket body 160. The compression piece 170 can be fixed to the bracket body 160 using screws.

[0101] Specifically, regarding the connection between the compression plate 170 and the bracket body 160, please refer to Figures 8 and 9. As shown in Figure 9, at least two positioning posts 163 are provided on the side of the bracket body 160 that contacts the compression plate 170, and positioning holes 171 are provided on the compression plate 170 to correspond to the positioning posts 163. The cooperation between the positioning posts 163 and the positioning holes 171 facilitates the installation of the compression plate 170 on the bracket body 160. Furthermore, two fastening holes are provided at both ends of the compression plate 170, and the positions of the fastening holes correspond to the positions of the two through-holes 161 in the bracket body 160. When the elastic bracket 150 is fixed to the second housing 121, screws can be inserted through the through-holes 161 in the bracket body 160 and the fastening holes in the compression plate 170, respectively. This secures the elastic bracket 150 to the second housing 121 as a whole, while also compressing the flexible cable 140 located between the compression plate 170 and the bracket body 160.

[0102] After tightening the first end of the flexible cable 140, the second end of the flexible cable 140 is passed through the gap between the bracket body 160 and the flexible cable 140, and the flexible cable 140 is wrapped around the crossbeam 183. The second end of the flexible cable 140 passes through the second housing 121 of the second part 120 and is electrically connected to the first electronic component in the first part 110. As shown in Figures 3 and 4, the routing shape of the flexible cable 140 on the elastic bracket 150 is "S"-shaped or "Z"-shaped, that is, the flexible cable 140 forms two bending areas on the elastic bracket 150. For ease of description, the two bending areas are referred to as the first bending area and the second bending area. The first bending area contacts the side of the bracket body 160 of the elastic bracket 150, and the second bending area contacts the side of the crossbeam 183 in the elastic component 180.

[0103] In the embodiment of the present application, the flexible cable 140 is fixed to the bracket body 160 by the compression piece 170 to prevent the connection between the flexible cable 140 and the second electronic component 122 from being loosened when the first portion 110 rotates relative to the second portion 120 and the flexible cable 140 is pulled toward the first portion 110. At the same time, fixing one end of the flexible cable 140 so that the other end of the flexible cable 140 is moved can cause the elastic component 180 in the bending area to deform, so that during the closing process, the elastic component 180 can retract the flexible cable 140 into the second portion 120.

[0104] In the elastic bracket 150 shown in FIG. 8 and FIG. 9 , both the first connecting member 181 and the second connecting member 182 are elastic.

[0105] When the electronic device is unfolded, the hinge cover 130 on the first portion 110 drives the flexible cable 140 to move, causing it to be pulled out of the second portion 120. Because the flexible cable 140 is wrapped around the crossbeam 183, the second bend of the flexible cable 140 drives the crossbeam 183 toward the first portion 110. Since both the first connector 181 and the second connector 182 are elastic, the pull of the crossbeam 183 causes the first and second connectors 181 and 182 to deform.

[0106] When the electronic device is closed, the hinge cover 130 on the first portion 110 no longer exerts tension on the flexible cable 140. In the absence of external forces, the first connector 181 and the second connector 182 recover their deformation, driving the crossbeam 183 to move away from the first portion 110. The crossbeam 183 within the second bending region drives the flexible cable 140 to retract the extended flexible cable 140 into the second portion 120.

[0107] It can be seen from the above description that the elastic bracket 150 shown in Figures 8 and 9 mainly provides elastic force through the first connecting member 181 and the second connecting member 182 to achieve the retraction of the pulled out flexible cable 140 into the second part 120.

[0108] Since the flexible cable 140 is mainly used for transmitting data, the flexible cable 140 will form friction with the crossbeam 183 during the process of being pulled out and pulled back. In order to avoid affecting the quality of the flexible cable 140 during the long-term friction process. In an embodiment of the present application, as shown in Figure 9, the crossbeam 183 includes a first support beam 1831 and a second support beam 1832, wherein the first support beam 1831 and the second support beam 1832 are attached together to form the crossbeam 183. The first support beam 1831 is a rigid beam, and the second support beam 1832 is a flexible beam. When the flexible cable 140 is wound around the crossbeam 183, the flexible cable 140 is in contact with the second support beam 1832. That is, the second bending area of ​​the flexible cable 140 is in contact with the second support beam 1832.

[0109] In this embodiment, as shown in FIG9 , the first connecting member 181, the second connecting member 182, and the second supporting beam 1832 can be integrally formed. Since the first connecting member 181 and the second connecting member 182 need to be elastic, and the second supporting beam 1832 is a flexible beam, the first connecting member 181, the second connecting member 182, and the second supporting beam 1832 can be made of silicone. Of course, other elastic and flexible materials can also be used to make the first connecting member 181, the second connecting member 182, and the second supporting beam 1832. Furthermore, if the first connecting member 181, the second connecting member 182, and the second supporting beam 1832 are made separately, they can also be made of an elastic material and the second supporting beam 1832 of a flexible material, and then the second supporting beam 1832 can be connected to the first connecting member 181 and the second connecting member 182.

[0110] First support beam 1831 can be manufactured using an injection molding process, but it must be made of a material with a certain hardness to ensure a certain strength. Second support beam 1832 can also be manufactured using an injection molding process. When manufacturing crossbeam 183, a two-color injection molding process can be used to simultaneously produce first support beam 1831 and second support beam 1832. Two-color injection molding involves injecting two different materials into the same mold, resulting in a molded part composed of two materials. Some materials may be different colors, or have different hardnesses, thereby improving the product's aesthetics and assembly performance.

[0111] Since the second support beam 1832 is a flexible beam, making the second support beam 1832 contact the flexible cable 140 can achieve soft contact between the flexible cable 140 and the crossbeam 183, avoiding long-term friction that causes damage to the flexible cable 140. At the same time, setting the first support beam 1831 as a rigid beam can provide a certain strength guarantee for the crossbeam 183, so that the crossbeam 183 can remain straight. This prevents the crossbeam 183 from being bent into a "crescent" shape when the flexible cable 140 drives the crossbeam 183 to move, causing the crossbeam 183 to deform and causing the flexible cable 140 to be locally subjected to excessive force. At the same time, it affects the deformation of the first connecting member 181 and the second connecting member 182.

[0112] In one embodiment of the present application, in order to ensure that the flexible cable 140 does not bend at a too small angle after being wound around the elastic bracket 150, which would affect data transmission of the flexible cable 140, when setting the elastic bracket 150, it is necessary to make the contact surface between the elastic bracket 150 and the flexible cable 140 as smooth as possible.

[0113] Referring to FIG10 , FIG10 is a partial cross-sectional schematic diagram of the elastic bracket 150 shown in FIG8 . As shown in FIG10 , the surface where the bracket body 160 contacts the first bending area of ​​the flexible cable 140 is the first contact surface 164, and the surface where the crossbeam 183 contacts the flexible cable 140 is the second contact surface 165. When setting the first contact surface 164 and the second contact surface 165, the first contact surface 164 and the second contact surface 165 can be set as arc surfaces. In order to ensure that the first contact surface 164 and the second contact surface 165 are as smooth as possible, the central angles corresponding to the first contact surface 164 and the second contact surface 165 can be set to be less than 90°. The smaller the central angles corresponding to the first contact surface 164 and the second contact surface 165, the smoother the first contact surface 164 and the second contact surface 165.

[0114] It should be noted that in the embodiment of the present application, when the first contact surface 164 and the second contact surface 165 are standard arc surfaces, the smoothness of the first contact surface 164 and the second contact surface 165 can be described by the size of the central angle. The first contact surface 164 and the second contact surface 165 can also be similar arc surfaces set with reference to the above-mentioned arc surfaces. Accordingly, they should be set as smooth as possible so that after the flexible cable 140 contacts the corresponding contact surface, the bending angle of the flexible cable 140 on the contact surface is greater than 90°. Of course, the first contact surface 164 and the second contact surface 165 can also be set as arc surfaces of other shapes, such as elliptical surfaces, or some non-standard arc surfaces. However, it is necessary to ensure that the first contact surface 164 and the second contact surface 165 are as smooth as possible. Specifically, the standard can be that the bending angle α of the flexible cable 140 is greater than 90° after the flexible cable 140 contacts the first contact surface 164, and the standard can be that the bending angle β of the flexible cable 140 is greater than 90° after the flexible cable 140 contacts the second contact surface 165. The above-mentioned bending angle α and bending angle β can be understood as the angles between the two positions where the flexible cable 140 is tangent to the end surface of the contact surface after the flexible cable 140 is attached to the corresponding contact surface.

[0115] This arrangement ensures that the flexible cable 140 will not generate large bends when it is routed around the elastic bracket 150, ensuring the smooth routing of the flexible cable 140 and avoiding the data transmission of the flexible cable 140 being affected by excessive bends. It should be noted that in a bending area mentioned in the embodiment of the present application, the flexible cable 140 may have two bends. For example, there are two bends in the first bending area of ​​the flexible cable 140 shown in Figure 10, one is the bend generated on the first contact surface 164, and the other is the bend generated from leaving the first contact surface 164 to contacting the beam 183. There are also two bends in the second bending area of ​​the flexible cable 140 shown in Figure 10, one is the bend generated on the second contact surface 165, and the other is the bend generated from the flexible cable 140 just after contacting the beam 183 to before contacting the second contact surface 165. At each of the above-mentioned bends, the bending angle of the flexible cable 140 is greater than 90°.

[0116] In another embodiment of the present application, another elastic bracket 150 is also provided. Referring to Figures 11 and 12, Figure 11 is a structural schematic diagram of another elastic bracket 150 in an electronic device provided in an embodiment of the present application, and Figure 12 is an exploded view of another elastic bracket 150 in an electronic device provided in an embodiment of the present application. As shown in Figures 11 and 12, the elastic bracket 150 also includes a bracket body 160, a pressing plate 170 and an elastic component 180. Among them, the pressing plate 170 is connected to one side of the bracket body 160, and the elastic component 180 is connected to the other side of the bracket body 160. The elastic bracket 150 shown in Figure 11 is similar in structure to the elastic bracket 150 shown in Figure 8, except that the structure of the elastic component 180 is different. It should be noted that there is another difference. In the structure shown in FIG11 , no positioning post 163 is provided on the bracket body 160, and no positioning hole 171 is provided on the pressure plate 170. The positioning post 163 and the positioning hole 171 are provided only to facilitate the installation of the pressure plate 170 on the bracket body 160, and do not affect the nature of the connection between the two. Of course, the positioning post 163 and the positioning hole 171 can also be provided in the structures shown in FIG11 and FIG12 with reference to the structure shown in FIG8 . The connection between the pressure plate 170 and the bracket body 160 in FIG11 and FIG12 can still refer to the connection method between the pressure plate 170 and the bracket body 160 in the elastic bracket 150 introduced in FIG8 and FIG9 , and will not be described in detail here.

[0117] As shown in Figures 11 and 12, the elastic assembly 180 includes a crossbeam 183, a first connecting member 181, and a second connecting member 182. The ends of the crossbeam 183 are fixedly connected to the bracket body 160 through the first connecting member 181 and the second connecting member 182. The difference is that the first connecting member 181 shown in Figures 11 and 12 has a different structure from the first connecting member 181 in Figures 8 and 9, and the second connecting member 182 shown in Figures 11 and 12 has a different structure from the second connecting member 182 in Figures 8 and 9.

[0118] In one embodiment of the present application, in the structure shown in FIG11 , the first connecting member 181 and the second connecting member 182 have the same structure and are symmetrically arranged at both ends of the crossbeam 183. The following uses the structure of the first connecting member 181 as an example to specifically describe the differences between the first connecting member 181 in the structure shown in FIG11 and the first connecting member 181 in the structure shown in FIG8 .

[0119] Referring to Figure 13, Figure 13 is a schematic structural diagram of the first connecting member 181 in the elastic bracket 150 shown in Figure 11. As shown in Figure 13, the first connecting member 181 includes a first crossbar 1811, a first vertical bar 1812, and a second crossbar 1813. The two ends of the first vertical bar 1812 are respectively connected to the first crossbar 1811 and the second crossbar 1813. The other end of the first crossbar 1811 is provided with a connector, and the first crossbar 1811 is fixedly connected to the bracket body 160 via the connector. The other end of the second crossbar 1813 is fixedly connected to the crossbar 183. The first vertical bar 1812 is perpendicular to the first crossbar 1811 and the second crossbar 1813, and the first crossbar 1811 is also perpendicular to the second crossbar 1813.

[0120] The first crossbar 1811, the first vertical bar 1812 and the second crossbar 1813 are all elastic. Through the above arrangement, when the flexible cable 140 drives the crossbar 183 to move, the crossbar 183 will drive the first crossbar 1811, the first vertical bar 1812 and the second crossbar 1813 to deform together. Compared to the first connecting member 181 shown in Figure 8, the first connecting member 181 composed of the first crossbar 1811, the first vertical bar 1812 and the second crossbar 1813 can have a larger deformation amount and is easier to deform when it is deformed. It should be noted that Figures 11 and 8 only show different shapes of the first connecting member 181. Those skilled in the art can also set the first connecting member 181 / the second connecting member 182 to other shapes as needed.

[0121] Continuing with Figures 11 and 12, aside from the aforementioned differences, the elastic bracket 150 shown in Figures 11 and 12 has the same structure as the elastic bracket 150 shown in Figures 8 and 9. For example, in the elastic bracket 150 shown in Figure 12, the crossbeam 183 also includes a first support beam 1831 and a second support beam 1832. The first support beam 1831 is a rigid beam, while the second support beam 1832 is a flexible beam. When the flexible cable 140 is wound around the crossbeam 183, the flexible cable 140 contacts the second support beam 1832. When the flexible cable 140 is wound around the elastic bracket 150 shown in Figure 11, the flexible cable 140 also forms an "S" or "Z" shape on the elastic bracket 150. When the elastic bracket 150 shown in Figures 11 and 12 contacts the flexible cable 140, it also includes a first contact surface 164 and a second contact surface 165. The configuration of the first contact surface 164 and the second contact surface 165 is similar to the description in the previous embodiment and will not be further described here.

[0122] In one embodiment of the present application, another elastic bracket 150 is further provided. Referring to Figures 14, 15, and 16, Figure 14 is a front structural diagram of another elastic bracket 150 in an electronic device provided in an embodiment of the present application, Figure 15 is a rear structural diagram of another elastic bracket 150 in an electronic device provided in an embodiment of the present application, and Figure 16 is an exploded view of another elastic bracket 150 in an electronic device provided in an embodiment of the present application.

[0123] As shown in Figures 14 to 16, the elastic bracket 150 includes a bracket body 160, a compression plate 170, and an elastic component 180. The compression plate 170 and the elastic component 180 are disposed on both sides of the bracket body 160. Regarding the coordination between the compression plate 170 and the bracket body 160, reference can be made to the relevant arrangements in the aforementioned embodiments and will not be elaborated upon here. The elastic component 180 includes a crossbeam 183, a first connecting member 181, a second connecting member 182, and an elastic member 184. The crossbeam 183 is connected to one side of the bracket body 160 via the first connecting member 181 and the second connecting member 182. A gap exists between the crossbeam 183 and the bracket body 160. The elastic member 184 is connected to one side of the crossbeam 183.

[0124] Unlike the structures shown in Figures 8 and 11 , in the elastic bracket 150 shown in Figure 14 , the first and second connectors 181 and 182 are used solely to connect the crossbeam 183 to the bracket body 160. These first and second connectors 181 and 182 are not elastic. Instead, the elastic member 184 is elastic. As shown in Figure 16 , in this elastic bracket 150 , the bracket body 160, the first and second connectors 181 and 182 can be integrally formed.

[0125] The routing shape of the flexible cable 140 wound around the elastic bracket 150 in FIG. 14 may refer to the routing described in the aforementioned embodiment, that is, the routing shape of the flexible cable 140 is set to an “S” shape or a “Z” shape.

[0126] When the flexible cable 140 is wound around the crossbeam 183 shown in Figure 14, the flexible cable 140 contacts the elastic member 184, that is, the elastic member 184 is located in the second bending area formed by the flexible cable 140. When the electronic device is unfolded, the flexible cable 140 is pulled out from the second part 120, and the flexible cable 140 squeezes the elastic member 184, causing the elastic member 184 to deform. When the electronic device is closed, since it is no longer under force, the elastic member 184 recovers its deformation and retracts the extended flexible cable 140 into the second part 120. The elastic member 184 can be made of foam, which has good deformation and recovery capabilities. Foam is a flexible material and is not prone to generating severe friction when in contact with the flexible cable 140, thereby avoiding damage to the flexible cable 140.

[0127] 15 , a fixing post 162 is further provided on the back of the bracket body 160 . When a wire blocking cloth 190 is required to be provided on one side of the flexible cable 140 , one end of the wire blocking cloth 190 may be fixedly connected to the fixing post 162 of the elastic bracket 150 .

[0128] In the above embodiments, three different elastic brackets 150 are introduced. The working principles of the three different elastic brackets 150 are basically the same, and the main differences are: the main difference between the elastic brackets 150 shown in Figures 8 and 11 is that the structures of the first connecting member 181 and the second connecting member 182 are different, that is, there are differences in the structures of the parts providing elasticity; the main difference between the elastic brackets 150 shown in Figures 8 (or 11) and 14 is that the ways of providing elastic force are different. The elastic bracket 150 shown in Figure 8 (or 11) mainly relies on the deformation of the first connecting member 181 and the second connecting member 182 to provide elastic force, and the elastic bracket 150 shown in Figure 14 mainly relies on the deformation of the elastic member 184 (foam) on the beam 183 to provide elastic force.

[0129] In another embodiment of the present application, an elastic bracket 150 is also provided. Referring to FIG17 , FIG17 is a schematic structural diagram of another elastic bracket 150 in an electronic device provided in an embodiment of the present application. As shown in FIG17 , the elastic bracket 150 includes a bracket body 160 and an elastic member 184 fixedly connected to the bracket body 160. In this structure, the elastic member 184 is a flexible object with elasticity, such as foam. Alternatively, the elastic member 184 includes a flexible shell filled with an elastic colloid. Alternatively, a spring is provided within the shell, allowing the entire elastic member 184 to deform and recover. The bracket body 160 is fixed to the second shell 121, and can be fixed by screws or gluing. The connection between the bracket body 160 and the second shell 121 can be seen in FIG5 and FIG6 . The elastic bracket 150 in FIG5 and FIG6 is the elastic bracket 150 shown in FIG17 .

[0130] As shown in Figure 17, the flexible cable 140 is wound around the elastic bracket 150. Specifically, the flexible cable is in direct contact with the elastic member 184, and the flexible cable is wound around the elastic member 184. A bending area is formed on the elastic member 184, and the elastic member 184 is located in the bending area. The routing shape of the flexible cable on the elastic member 184 is "U"-shaped. Among them, the end of the flexible cable 140 connected to the second electronic device is pressed against the second shell 121 by the clamping plate 170, so that when the flexible cable is pulled out of the second part 120, it can squeeze the elastic member 184, causing the elastic member 184 to deform. Therefore, during the closing process, the elastic member 184 in the elastic bracket 150 can restore the deformation and pull back the flexible cable 140 pulled out of the second part 120. The connection between the clamping plate 170 and the second shell 121 can be fixed by screw connection.

[0131] It should be noted that the contact between the elastic member 184 shown in Figure 17 and the bending area of ​​the flexible cable 140 also includes a first contact surface and a second contact surface (the contact surfaces formed at the two corners of the elastic member 184 in Figure 17). The setting of the first contact surface and the second contact surface can be designed according to the relevant requirements in the aforementioned embodiment (making the bending angle of the flexible cable 140 greater than 90°) to avoid the flexible cable 140 from forming a bend with a smaller angle.

[0132] In one embodiment of the present application, a cable blocking cloth 190 is further provided in the electronic device. The cable blocking cloth 190 is provided on one side of the flexible cable 140. When the electronic device is unfolded or closed, the cable blocking cloth 190 shields the flexible cable 140 from view, preventing the flexible cable 140 at the connection between the first portion 110 and the second portion 120 from being directly exposed to the view and affecting the aesthetics of the electronic device. At the same time, the cable blocking cloth 190 protects the flexible cable 140 from contact with sharp objects outside, thereby preventing sharp objects from damaging the flexible cable 140.

[0133] When the wire blocking cloth 190 is set, the wire blocking cloth 190 can be attached to the flexible cable 140 that needs to be shielded. Referring back to Figure 3, as shown in Figure 3, the wire blocking cloth 190 is attached to the flexible cable 140, and the wire blocking cloth 190 can move along with the flexible cable 140. One end of the wire blocking cloth 190 is fixedly connected to the elastic bracket 150. Specifically, as shown in Figure 3, the clamping piece 170 on the elastic bracket 150 can be used to press the wire blocking cloth 190 and the flexible cable 140 together on the bracket body 160. The wire blocking cloth 190 is routed along with the flexible cable 140. After the other end of the wire blocking cloth 190 passes through the second shell 121, it enters the rotating shaft cover 130 of the first part 110, and the other end of the wire blocking cloth 190 is fixedly connected to the rotating shaft cover 130 by the clamping device 191.

[0134] In addition, the cable blocking cloth 190 and the flexible cable 140 may not be attached together, that is, the cable blocking cloth 190 and the flexible cable 140 are in a separated state, and the cable blocking cloth 190 is arranged on one side of the flexible cable 140. The connection method of the cable blocking cloth 190 in the electronic device can be referred to Figure 18, which is another partial cross-sectional view of an electronic device provided in an embodiment of the present application.

[0135] As shown in Figure 18, one end of the wire blocking cloth 190 is fixedly connected to the fixing post 162 on the back of the elastic bracket 150, and the other end of the wire blocking cloth 190 passes through the second shell 121 and enters the shaft cover 130 of the first part 110, and the other end of the wire blocking cloth 190 is fixedly connected to the shaft cover 130 by the clamping device 191. It should be noted that the elastic bracket 150 shown in Figure 18 is the elastic bracket 150 shown in Figure 14. Since the elastic bracket 150 shown in Figures 8 and 11 can also be provided with a fixing post 162 on the back of its bracket body 160, the elastic bracket 150 in Figure 18 can also be replaced with the elastic bracket 150 shown in Figures 8 and 11, and the replacement does not affect the connection of the wire blocking cloth 190 in the second part 120.
