Description

Technical Field

[0001] This application relates to the field of displays, and more particularly to a connection mechanism and a display device. Background Technology

[0002] With the rapid development of display technology, there are now many different types of monitors on the market, such as flat screen monitors and curved screen monitors. Due to the different designs of the two types, the connection methods for connecting the printed circuit board to the back panel are also different. In flat screen monitors, the printed circuit board is usually connected horizontally to the display panel and the back panel, while in curved screen monitors, the printed circuit board is generally folded to the back of the back panel for connection.

[0003] Traditional connection devices used to connect printed circuit boards to backplanes can only be used for one type of display. When assembling printed circuit boards and backplanes for different models, different connection devices need to be used. Furthermore, since the flexible cables used to connect the display panel and the printed circuit board have a fixed length, the possibility of switching connection methods between different models is further limited, which greatly affects product applicability and increases assembly difficulty and cost.

[0004] Therefore, how to adapt to the connection between printed circuit boards and backplanes of different models without affecting the connection between flexible cables and printed circuit boards has become an urgent problem to be solved in this field. Summary of the Invention

[0005] This application discloses a connection mechanism and a display device, the purpose of which is to adapt to the connection between printed circuit boards and backplanes of different models without affecting the connection between flexible cables and printed circuit boards, thereby improving product applicability.

[0006] This application discloses a connection mechanism for connecting a display panel, a printed circuit board, and a back panel. The connection mechanism includes a connecting device, a fixing device, and a storage device. One side of the connecting device is connected to the back panel, and the other side is connected to the fixing device. The fixing device is used to fix the printed circuit board. The connecting device includes multiple locking structures connected end-to-end, and adjacent locking structures are rotatably connected. The multiple locking structures rotate relative to each other, causing the fixing device to be parallel to the back panel or folded to the back of the back panel. The storage device is disposed between the display panel and the printed circuit board and is connected to the back panel. The storage device includes a housing and an adjustment component. The adjustment component is disposed within the housing, and a flexible cable portion is stored within the housing. The adjustment component adjusts the length of the flexible cable extending out of the housing according to the distance the fixing device folds relative to the back panel.

[0007] Optionally, the housing includes a top wall and a bottom wall disposed opposite to each other, and four side walls surrounding the top wall and the bottom wall. A first opening is provided on the top wall, and a second opening is provided on the bottom wall. The two ends of the flexible cable extend from the first opening and the second opening, respectively. The adjustment assembly includes multiple adjustment members, a placement structure, and multiple first elastic members. The multiple first elastic members are spaced apart along the side walls from the top wall to the bottom wall. One end of each pair of adjacent first elastic members is connected to the corresponding two side walls. The placement structure supports the adjustment members. The other end of each first elastic member is connected to each adjustment member. The elastic extension / retraction direction of the first elastic member is perpendicular to the adjustment member, and the first elastic member drives the adjustment member to move along the elastic extension / retraction direction of the first elastic member. The multiple adjustment members are staggered along the top wall to the bottom wall. The flexible cable passes sequentially through the side of each adjacent adjustment member away from the first elastic member.

[0008] Optionally, the adjusting member is a tubular structure, and the sidewall includes a first sidewall and a second sidewall that correspond to each other. The first sidewall and the second sidewall are located on both sides of the length direction of the adjusting member. The first sidewall is provided with a plurality of first sliding grooves spaced apart from the top wall to the bottom wall, and the second sidewall is provided with a plurality of second sliding grooves spaced apart from the top wall to the bottom wall. Each first sliding groove corresponds to each second sliding groove in a one-to-one manner. Both the first sliding groove and the second sliding groove are elongated, and the extension direction of the first sliding groove and the second sliding groove is the same as the elastic extension direction of the first elastic member. The placement structure includes a plurality of bearings, and the two ends of each bearing are respectively embedded in the first sliding groove and the second sliding groove arranged in the same layer, and can move along the extension direction of the first sliding groove and the second sliding groove. Each adjusting member is sleeved on the bearing.

[0009] Optionally, the adjusting component includes a telescopic sleeve, which is composed of multiple segments of tubing nested in sequence. Both ends of the telescopic sleeve are telescopic, and the length of the telescopic sleeve when it reaches its maximum elongation is greater than or equal to the width of the first opening and the second opening.

[0010] Optionally, the storage device further includes a control motor, which is disposed inside the housing and connected to the telescopic sleeve to control the telescopic sleeve to extend and retract along the width direction of the flexible cable.

[0011] Optionally, the fixing device includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate being spaced apart, the first clamping plate and the second clamping plate clamping the printed circuit board from both sides in the width direction of the printed circuit board.

[0012] Optionally, the locking structure includes a locking housing and a rotating component. The rotating component is disposed within the locking housing and includes a rotating body and a connecting plate. Both the rotating body and the locking housing are cylindrical. One side of the connecting plate is connected to the outer side of the rotating body. The locking structure includes a first locking structure and a second locking structure arranged adjacent to each other. In the first locking structure, the locking housing has a first through groove corresponding to the position of the connecting plate. One side of the connecting plate is connected to the rotating body, and the other side extends out from the first through groove. In the second locking structure, the locking housing also has a second through groove corresponding to the position of the connecting plate of the first locking structure. The connecting plate of the first locking structure extends into the second through groove and is rotatably connected to the locking housing.

[0013] Optionally, both the first and second locking structures have movable components within their housings. These movable components include an electromagnet, a second elastic element, and a locking element. Within the housing of the second locking structure, the electromagnet is positioned close to the connecting plate of the first locking structure and is rotatably connected to the locking housing. The connecting plate of the first locking structure passes through the second through slot and connects to one side of the electromagnet. The other side of the electromagnet is connected to one end of the second elastic element, and the other end of the second elastic element is connected to the locking element. The locking element is magnetic; when the electromagnet is de-energized, the locking element limits the rotating body in the second locking structure; when the electromagnet is energized, the locking element disengages from the rotating body in the second locking structure.

[0014] Optionally, the locking member has multiple positioning teeth on the side away from the second elastic member, and the rotating bodies of both the first and second locking structures have multiple teeth on their outer surfaces. The positioning teeth engage with the teeth. When the electromagnet is de-energized, the positioning teeth engage with the teeth of the rotating body in the second locking structure. When the electromagnet is energized, the electromagnet attracts the locking member, and the positioning teeth disengage from the teeth of the rotating body in the second locking structure.

[0015] This application also discloses a display device, including a display panel, a back plate, a flexible cable, and a printed circuit board, wherein the back plate encloses the display panel; the display device further includes the aforementioned connecting mechanism, wherein a portion of the flexible cable is housed within a receiving device of the connecting mechanism, one end of the flexible cable is connected to the display panel, and the other end is connected to the printed circuit board, wherein the printed circuit board is fixed on a fixing device of the connecting mechanism and connected to the back plate through a connecting device of the connecting mechanism.

[0016] This application improves the connection mechanism for connecting a printed circuit board (PCB) to a backplane. The connection device connects the PCB to the backplane using a chain-like structure formed by multiple locking mechanisms connected end-to-end. The rotation of these locking mechanisms between movable components allows the entire connection device to be adjusted relative to the backplane. Depending on the type of display device, the fixing device can be moved parallel to the backplane or folded to the back of the backplane. Furthermore, during the adjustment of the fixing device, the distance between the PCB and the display panel changes. Therefore, the length of the flexible cable is adjusted using the adjustment component in the storage device to accommodate the change in distance between the PCB and the display panel. The installed flexible cable is housed in a storage device, which is then fixed to the side of the back panel. One end of the flexible cable extends from the housing of the storage device toward the display panel and is bound to it, while the other end extends from the side away from the display panel and is bound to the printed circuit board. The portion of the flexible cable inside the storage device is folded by the device. When switching from a flat-panel model to a curved-panel model, the storage device is operated to leave a longer flexible cable, the locking mechanism is adjusted to fold the printed circuit board to the back of the back panel, and the storage device is adjusted again to ensure a suitable binding length between the flexible cable and the printed circuit board. This allows for the connection between the printed circuit board and the back panel of different models without affecting the connection between the flexible cable and the printed circuit board, thus improving product applicability.

[0019] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Figure 1 This is a schematic diagram of the first embodiment of the connecting mechanism of this application; as shown Figure 1As shown, this application discloses a connection mechanism 100 for connecting a display panel, a printed circuit board 500, and a back panel 300. The connection mechanism 100 includes a connection device 110, a fixing device 140, and a storage device 150. One side of the connection device 110 is connected to the back panel 300, and the other side is connected to the fixing device 140. The fixing device 140 is used to fix the printed circuit board 500. The connection device 110 includes a plurality of locking structures 111 connected end to end. The first locking structure 111 near the back panel 300 and the two adjacent locking structures 111 are provided with movable components 130. The two adjacent locking structures 111 are connected in sequence. 1. The device is rotatably connected via the movable component 130; multiple locking structures 111 rotate relative to each other, causing the fixing device 140 to be parallel to the back plate 300 or folded to the back of the back plate 300; the storage device 150 is disposed between the display panel and the printed circuit board 500 and is connected to the back plate 300, for partially storing the flexible cable 400; the storage device 150 includes a housing 151 and an adjustment component 170, the adjustment component 170 is disposed inside the housing 151, and the flexible cable 400 is partially stored inside the housing 151; the adjustment component 170 adjusts the length of the flexible cable 400 according to the distance the fixing device 140 folds relative to the back plate 300.

[0021] This application improves the connection mechanism 100 used to connect the printed circuit board 500 to the back plate 300. The fixing device 140 in the connection mechanism 100 first fixes the printed circuit board 500 to the connection mechanism 100 to prevent the printed circuit board 500 from shaking and ensure the stability of the connection. Then, the connection device 110 connects the printed circuit board 500 to the back plate 300. The connection device 110 is a chain-like structure formed by multiple locking structures 111 connected end to end, and adjacent locking structures 111 are rotatably connected by a movable component 130, so that the movable component 130 is integral to the entire connection device 100. The internal structure 10 forms a joint-like function. Multiple locking structures 111, through rotation between the movable components 130, allow the entire connecting device 110 to be adjusted relative to the back panel 300. Depending on the type of display device 10, the fixing device 140 can be moved parallel to the back panel 300 or folded to the back of the back panel 300. Furthermore, during the adjustment of the fixing device 140, the distance between the printed circuit board 500 and the display panel 200 changes. Therefore, the length of the flexible cable 400 is adjusted by the adjusting component 170 in the storage device 150 to accommodate the change in distance between the printed circuit board 500 and the display panel 200. The flexible cable 400 to be installed is housed in the housing 150, and the housing 150 is fixed to the side of the back plate 300 (the housing of the housing 150 can be glued or screwed to the back plate 300). One end of the flexible cable 400 extends from the housing of the housing 150 toward the display panel 200 and is bound to the display panel 200. The other end extends from the side away from the display panel 200 and is bound to the printed circuit board 500. The portion of the flexible cable 400 located inside the housing 150 is... The storage device 150 is folded; when switching from a flat model to a curved model, the storage device 150 is operated to leave a longer flexible cable 400, and the locking structure 111 is adjusted to fold the printed circuit board 500 to the back of the back plate 300. Then, the storage device 150 is adjusted to ensure that the flexible cable 400 and the printed circuit board 500 have a suitable binding length. This can accommodate the connection between the printed circuit board 500 and the back plate 300 of different models without affecting the connection between the flexible cable 400 and the printed circuit board 500, thus improving the applicability of the product.

[0022] Figure 2 This is a schematic diagram of the storage device in the first embodiment of the connection mechanism of this application; Figure 3 This is a side view of the storage device in the first embodiment of the connecting mechanism of this application; Figure 4 This is a schematic diagram of the housing device loading a flexible cable in the first embodiment of the connection mechanism of this application; as shown. Figures 2 to 4 As shown, the housing 151 includes a top wall 154 and a bottom wall 155 disposed opposite to each other, and four side walls 156 disposed between the top wall 154 and the bottom wall 155. A first opening 152 is provided on the top wall 154, and a second opening 153 is provided on the bottom wall 156. The two ends of the flexible cable 400 extend from the first opening 152 and the second opening 153 respectively. The adjustment assembly 170 includes multiple adjustment members 171, a placement structure 173, and multiple first elastic members 175. The multiple first elastic members 175 are spaced apart along the sidewalls 156 from the top wall 154 to the bottom wall 155, with one end of each adjacent first elastic member 175 connected to its corresponding sidewalls 156. The placement structure 173 supports the adjustment members 171, and the other end of each first elastic member 175 is connected to each adjustment member 171. The elastic extension / retraction direction of the first elastic member 175 is perpendicular to the extension / retraction direction of the adjustment member 171, allowing the adjustment member 171 to move along its elastic extension / retraction direction. The length of the first elastic member 175 in its natural state is greater than half the width of the top wall 154 and the bottom wall 155, and the multiple adjustment members 171 are staggered along the direction from the top wall 154 to the bottom wall 155. A flexible cable 400 passes sequentially through the side of each adjacent adjustment member 171 away from the first elastic member 175.

[0023] During the process of inserting the flexible cable 400 into the storage device 150, one end of the flexible cable 400 is first inserted through the first opening 152 of the housing 151, then passes sequentially through the side of each adjusting member 171 away from the first elastic member 175, and finally exits through the second opening 153 of the housing 151. This causes the portion of the flexible cable 400 inside the housing 151 to form a zigzag shape. This allows a longer portion of the flexible cable 400 to be accommodated in the storage device 150, so that the length of the flexible cable 400 can be adjusted by pulling it out or retracting it according to actual usage. Furthermore, because the adjusting members 171 and... When the flexible cable 400 comes into contact, it will exert a force on the flexible cable 400 away from the first elastic element 175 under the elastic action of the first elastic element 175. The flexible cable 400 will exert a relative squeezing force on the adjusting element 171, so that the flexible cable 400 is taut between the multiple adjusting elements 171. When the fixing device 140 is folded to the back of the back plate 300 for fixing, if a longer flexible cable 400 is needed, one end of the flexible cable 400 can be stretched outward. When the fixing device 140 is installed parallel to the back plate 300, the flexible cable 400 can also be directly stored in the housing 151 if it is too long.

[0024] The adjusting member 171 is a tubular structure, and its sidewall 156 includes corresponding first sidewalls 157 and second sidewalls 159. The first sidewalls 157 and second sidewalls 159 are located on opposite sides of the adjusting member 171 along its length. The first sidewall 157 has a plurality of first grooves 158 spaced apart from the top wall 154 to the bottom wall 155, and the second sidewall 159 has a plurality of second grooves 160 spaced apart from the top wall 154 to the bottom wall 155. Each first groove 158 is associated with a second groove 160. The positions of the slide grooves 160 are one-to-one. The first slide groove 158 and the second slide groove 160 are both elongated. The extension direction of the first slide groove 158 and the second slide groove 160 is the same as the elastic extension direction of the first elastic member 175. The placement structure 173 includes multiple bearings 174. The two ends of each bearing 174 are respectively embedded in the first slide groove 158 and the second slide groove 160 arranged in the same layer, and can move along the extension direction of the first slide groove 158 and the second slide groove 160. Each adjusting member 171 is sleeved on the bearing 174.

[0025] By providing multiple first grooves 158 and second grooves 160 on the first sidewall 157 and the second sidewall 159 respectively, the two ends of the bearing 174 are embedded into the first grooves 158 and the second grooves 160. This allows the first sidewall 157 and the second sidewall 159 to stably support the bearing 174 through the first grooves 158 and the second grooves 160, and enables the bearing 174 to move along the extension direction of the first grooves 158 and the second grooves 160. Since the extension direction of the first grooves 158 and the second grooves 160 is the same as the elastic extension direction of the spring, when the adjusting member 171 is fitted onto the bearing 174, during the extension or compression of the spring, the adjusting member 171 moves, and the bearing 174 moves along the extension direction of the spring along with the adjusting member 171. Furthermore, the support of the adjusting member 171 by the bearing 174 prevents the adjusting member 171 from deforming during movement, thus maintaining the structural stability of the adjusting member 171.

[0026] Figure 5 This is a partial schematic diagram of the connecting device in the first embodiment of the connecting mechanism of this application. Figure 6 This is a schematic diagram of the locking element in the first embodiment of the connecting mechanism of this application; Figure 7 This is a schematic diagram of the rotating member in the first embodiment of the connecting mechanism of this application; as shown Figures 5 to 7 As shown, the locking structure 111 includes a locking housing 112 and a rotating member 117. The rotating member 117 is disposed inside the locking housing 112 and includes a rotating body 118 and a connecting plate 120. Both the rotating body 118 and the locking housing 112 are cylindrical. One side of the connecting plate 120 is connected to the outer side of the rotating body 118. The locking structure 111 includes a first locking structure 121 and a second locking structure 122 arranged adjacent to each other. In the first locking structure 121, the locking housing 112 is provided with a first through groove 113 at the position corresponding to the connecting plate 120. One side of the connecting plate 120 is connected to the outer side of the rotating body 118, and the other side extends out from the first through groove 113. The connecting plate 120 in the first locking structure 121 can rotate along the slotting direction of the first through groove 113, and the rotation angle of the connecting plate 120 is greater than or equal to 90°. In the second locking structure 122, the locking housing 112 is also provided with a second through groove 114 at the position corresponding to the connecting plate 120 of the first locking structure 121. The connecting plate 120 of the first locking structure 121 extends into the second through groove 114 and is rotatably connected to the locking housing 112. The connecting plate 120 of the first locking structure 121 can rotate along the slotting direction of the second through groove 114, and the rotation angle of the connecting plate 120 in the second through groove 114 is greater than or equal to 90°.

[0027] Since both the locking housing 112 and the rotating body 118 located within the locking housing 112 are cylindrical in this application, the rotating body 118 can rotate relative to the locking housing 112 within the locking housing 112. When the rotating body 118 rotates, it drives the connecting plate 120 to rotate. The range of rotation of the connecting plate 120 and the rotating body 118 depends on the opening size of the first through slot 113 and the second through slot 114. When the connecting plate 120 in the first locking structure 121 extends out of the first through slot 113 and into the first through slot 114 on the locking housing 112 in the second locking structure 122... After the two-way slot 114 is connected to the locking housing 112 of the second locking structure 122, the connecting plate 120 of the first locking structure 121 not only connects the two adjacent locking structures 111, but also allows the two adjacent locking structures 111 to rotate relative to each other through the connecting plate 120. When the angle of rotation of the connecting plate 120 between the two adjacent locking structures 111 is greater than or equal to 90°, after the multiple locking structures 111 rotate together, the entire connecting device 110 can be more easily folded to the back of the back plate 300 or kept horizontal with the back plate 300.

[0028] Specifically, the movable component 130 is disposed within the locking housing 112 of the second locking structure 122. The movable component 130 includes an electromagnet 131, a second elastic element 133, and a locking element 134. The electromagnet 131 is disposed near the connecting plate 120 of the first locking structure 121, and rotating shafts 132 are provided at both ends of the electromagnet 131. The locking housing 112 is provided with rotating shaft holes 115 corresponding to the positions of the rotating shafts 132. The rotating shafts 132 are inserted into the rotating shaft holes 115, rotatably connecting the electromagnet 131 and the locking housing 112. The connecting plate 120 of the first locking structure 121 passes through the second through groove 114 and is connected to one side of the electromagnet 131. The other side of the electromagnet 131 is connected to the second elastic element 134. One end of the first locking element 133 is connected to the second elastic element 133, and the other end of the second elastic element 133 is connected to the locking element 134. The locking element 134 is magnetic, and a plurality of positioning teeth 135 are provided on the side of the locking element 134 away from the second elastic element 133. A plurality of teeth 119 are provided on the outer surface of the rotating body 118 of the first locking structure 121 and the second locking structure 122. The positioning teeth 135 cooperate with the teeth 119. When the electromagnet 131 is de-energized, the positioning teeth 135 engage with the teeth 119 of the rotating body 118 in the second locking structure 122. When the electromagnet 131 is energized, the electromagnet 131 attracts the locking element 134, and the positioning teeth 135 disengage from the teeth 119 of the rotating body 118 in the second locking structure 122.

[0029] In the adjacent first locking structure 121 and second locking structure 122, the connecting plate 120 of the first locking structure 121 is connected to the electromagnet 131 in the locking housing 112 of the second locking structure 122. The electromagnet 131 is connected through the rotating shaft 132 and the rotating shaft hole 115 on the locking housing 112 of the second locking structure 122, thus realizing the rotatable connection between the connecting plate 120 of the first locking structure 121 and the second locking structure 122.

[0030] Furthermore, this application utilizes the movable component 130 between the first locking structure 121 and the second locking structure 122 to control the rotation and locking of two adjacent locking structures 111. When the printed circuit board 500 needs to be adjusted in position, the movable component 130 is used to allow the two adjacent locking structures 111 to rotate. When the printed circuit board 500 needs to be fixed, the movable component 130 is used to lock the two adjacent locking structures 111 to prevent the locking structures 111 from rotating.

[0031] Furthermore, a power supply can be installed within the connecting mechanism 100 or on the back plate 300 to power the electromagnet 131 and control the electromagnet 131 to generate electromagnetic properties. The specific working principle is as follows: When the electromagnet 131 is energized, an attractive force is generated between the electromagnet 131 and the locking member 134. The locking member 134 is attracted by the electromagnet 131 and moves towards the electromagnet 131. During the movement of the locking member 134, it compresses the second elastic member 133. The positioning teeth 135 of the locking member 134 disengage from the teeth 119 of the rotating body 118 in the second locking structure 122. The first locking structure 121 and the second locking structure 122 can rotate, and the entire connecting device can be adjusted by the mutual rotation of multiple locking structures 111. The relative position between the position 110 and the back plate 300; when the electromagnet 131 is de-energized, there is no attraction between the electromagnet 131 and the locking member 134. At this time, the compressed second elastic member 133 will release the compression amount and push the locking member 134 away from the electromagnet 131 until the positioning tooth 135 of the locking member 134 engages with the tooth 119 of the rotating body 118 in the second locking structure 122, so that the first locking structure 121 and the second locking structure 122 are locked, forming the final fixed shape, and the printed circuit board 500 is connected through the connecting device 110.

[0032] Furthermore, both sides of the locking member 134 are provided with protrusions 136, and the lock housing 112 is provided with a groove 116 corresponding to the position of the protrusions 136. The protrusions 136 are embedded in the grooves 116 and can slide in the extension direction of the grooves 116.

[0033] When electromagnet 131 is energized, an attractive force is generated between electromagnet 131 and locking member 134. Locking member 134 moves along slide groove 116 towards electromagnet 131 using the protrusions 136 on both sides, moving away from rotating body 118 in second locking structure 122. When electromagnet 131 is de-energized, there is no attractive force between electromagnet 131 and locking member 134. At this time, the compressed first elastic member 175 releases its compression, pushing locking member 134 away from electromagnet 131. At this time, the protrusions 136 on both sides of locking member 134 move along slide groove 116 away from electromagnet 131. The movement path of locking member 134 is restricted by the cooperation of slide groove 116 and protrusions 136, making the movement of locking member 134 more stable within housing 151 and less prone to positional displacement.

[0034] Figure 8 This is a schematic diagram of the fixing device in the first embodiment of the connecting mechanism of this application, as shown below. Figure 8 As shown, the fixing device 140 in this application includes a first clamping plate 141 and a second clamping plate 142. The first clamping plate 141 and the second clamping plate 142 are spaced apart and clamp the printed circuit board 500 from both sides in the width direction of the printed circuit board 500.

[0035] When assembling the printed circuit board 500 with the fixing device 140, it is only necessary to embed the printed circuit board 500 between the first clamping plate 141 and the second clamping plate 142, so that the first clamping plate 141 and the second clamping plate 142 clamp the printed circuit board 500 from both sides in the width direction of the printed circuit board 500, and the installation of the printed circuit board 500 with the fixing device 140 can be completed. The installation is simple and convenient, and the printed circuit board 500 can be easily replaced. In addition, the clamping and fixing method makes it difficult for the printed circuit board 500 to fall off the fixing device 140, further improving the stability of the fixed printed circuit board 500.

[0036] Figure 9 This is a schematic diagram of the storage device in the second embodiment of the connecting mechanism of this application, as shown below. Figure 9 As shown, the adjusting member 171 includes a telescopic sleeve 172, which is composed of multiple segments of tubular body nested in sequence. Both ends of the telescopic sleeve 172 can be extended and retracted. When the telescopic sleeve 172 reaches its maximum elongation, its length is greater than or equal to the width of the first opening 152 and the second opening 153.

[0037] When it is necessary to adapt flexible cables 400 of different widths, the extension or retraction of the telescopic sleeve 172 can be adjusted to match the length of the telescopic sleeve 172 with the width of the flexible cable 400. Multiple telescopic sleeves 172 are used to support the flexible cable 400, and the flexible cable 400 is straightened under the action of the first elastic element 175. Since both ends of the flexible cable 400 need to extend from the first opening 152 and the second opening 153, the width of the first opening 152 and the second opening 153 needs to be greater than the width of the flexible cable 400. Therefore, when the length of the telescopic sleeve 172 at its maximum extension is greater than or equal to the width of the first opening 152 and the second opening 153, it can adapt to flexible cables 400 of different widths well and there will be no mismatch.

[0038] Furthermore, the storage device 150 also includes a control motor 180, which is housed within the housing 151 and connected to the telescopic sleeve 172. The control motor 180 controls the telescopic sleeve 172 to extend or retract along the width of the flexible cable 400. By using the forward or reverse rotation of the control motor 180 to drive the extension or retraction of the telescopic sleeve 172, the amount of extension and retraction of the telescopic sleeve 172 can be precisely controlled. This allows for better matching of flexible cables 400 of different widths, effectively utilizing the space of the housing 151 and improving the storage efficiency of the storage device 150 for the flexible cable 400.

[0039] Furthermore, the first elastic element 175 includes a spring connected to the middle of the telescopic sleeve 172, and the spring is perpendicular to the telescopic sleeve 172. When the flexible cable 400 is not installed, the elasticity of the spring itself generates a pulling force perpendicular to the direction of the telescopic sleeve 172, so that the telescopic sleeve 172 can remain relatively stationary within the housing 151. When the flexible cable 400 passes through the staggered telescopic sleeves 172 in sequence, it generates a compressive force on the telescopic sleeve 172 in the direction of the spring. After being compressed, the spring begins to compress, allowing the telescopic sleeve 172 to move along the extension and retraction direction of the spring. Since the spring is connected to the middle of the telescopic sleeve 172, when the spring pulls the telescopic sleeve 172, the elastic force acts on the middle of the telescopic sleeve 172, so that the telescopic sleeve 172 can move smoothly along the extension and retraction direction of the spring.

[0040] Figure 10 This is a schematic diagram of an embodiment of the display device of this application, as shown below. Figure 10As shown, this application also discloses a display device 10, including a display panel 200, a back plate 300, a flexible cable 400, and a printed circuit board 500. The back plate 300 covers the display panel 200. The display device 10 also includes the aforementioned connecting mechanism 100. The flexible cable 400 is partially housed in the receiving device 150 of the connecting mechanism 100. One end of the flexible cable 400 is connected to the display panel 200, and the other end is connected to the printed circuit board 500. The printed circuit board 500 is fixed on the fixing device 140 of the connecting mechanism 100 and connected to the back plate 300 through the connecting device 110 of the connecting mechanism 100.

[0041] The display panel 200 is typically connected to the printed circuit board 500 via a flexible cable 400. The printed circuit board 500 provides drive signals to the display panel 200. After the printed circuit board 500 is connected from the display panel 200, it needs to be fixed. First, the printed circuit board 500 is fixed to the connecting mechanism 100, and then the printed circuit board 500 is connected and fixed to the back plate 300 using the connecting mechanism 100. This makes the printed circuit board 500 stable and less prone to shaking or falling off, thus providing a stable signal output to the display panel 200 and ensuring the quality of the display device 10.

[0042] The usual connection mechanism 100 is fixed and cannot be adjusted for a specific type of display device 10. Therefore, when fixing the printed circuit board 500 in different types of display devices 10, the same connection mechanism 100 often cannot be used. Furthermore, after adjusting the installation position of the printed circuit board 500, the length of the flexible cable 400 connected to the printed circuit board 500 also needs to be adjusted, which increases the complexity of assembly and the assembly cost.

[0043] To address the aforementioned issues, this application improves the connection mechanism 100 in the display device 10 used to connect the printed circuit board 500 to the back plate 300. The fixing device 140 in the connection mechanism 100 first fixes the printed circuit board 500 to the connection mechanism 100, preventing the printed circuit board 500 from shaking and ensuring the stability of the connection. Then, the connection device 110 connects the printed circuit board 500 to the back plate 300. The connection device 110 is a chain-like structure formed by multiple locking structures 111 connected end-to-end. Adjacent locking structures 111 are rotatably connected by a movable component 130, which acts like a "joint" within the entire connection device 110. The rotation of the multiple locking structures 111 between the movable component 130 allows the position of the entire connection device 110 relative to the back plate 300 to be adjusted. Depending on the type of display device 10, the fixing device 140 can be moved parallel to the back plate 300 or folded to the back of the back plate 300. Furthermore, the fixing device... During the adjustment process at 140, the distance between the printed circuit board 500 and the display panel 200 changes. The flexible cable 400 to be installed is then stored in the storage device 150, and the storage device 150 is fixed to the side of the back plate 300. One end of the flexible cable 400 extends from the housing of the storage device 150 towards the display panel 200 and is bound to it. The other end extends from the side away from the display panel 200 and is bound to the printed circuit board 500. The flexible cable 400 is located within the storage device 150. The inner part is folded by the storage device 150. When switching from a flat model to a curved model, the storage device 150 is operated to leave a longer flexible cable 400. The locking structure 111 is adjusted to fold the printed circuit board 500 to the back of the back plate 300. The storage device 150 is then adjusted to ensure that the flexible cable 400 and the printed circuit board 500 have a suitable binding length. This allows for the connection between the printed circuit board 500 and the back plate 300 of different models without affecting the connection between the flexible cable 400 and the printed circuit board 500, thus improving the applicability of the product.
