DETAILED DESCRIPTION

[0055] In the related art, a socket is provided on the rear side of the front seat of the vehicle so that the user can plug in the bracket of the fixed terminal to fix the terminal and charge the terminal. Generally, in order to prevent the plug socket from being exposed to external dust and impurities when not in use, an openable cover is provided on the plug socket. The existing cover is generally installed by rotating the shaft, and the plug socket is opened by flipping inward.

[0056] However, the existing installation method of the cover requires moving the plug-in terminal back a large distance to form an escape space between the plug-in terminal and the cover for flipping when the cover is opened and closed, resulting in a larger size of the plug socket in the seat thickness direction, affecting layout and installation.

[0057] In view of the above problems, the present invention provides a plug interface and a car seat, which can reduce the size of the plug interface device in the thickness direction of the car seat back, so that the plug interface device can be more conveniently integrated into the seat back.

[0058] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0062] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0063] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0064] The overall structure, working principle and technical effects of the plug-in interface device and the automobile seat provided by the present invention are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0065] Please refer to Figures 1 to 8 The automobile seat includes a seat body and a plug-in interface device 100 installed on the back of the seat body backrest. The plug-in interface device 100 is used to plug and install a terminal bracket, such as a tablet bracket, so as to support and fix the tablet and charge the tablet at the same time. The plug-in interface device 100 can even enable the connected terminal device such as the tablet to establish a connection with the vehicle to control the vehicle.

[0066] Please refer to Figures 1 to 8In this embodiment, the plug interface device 100 includes a plug terminal 110, a shell 130 and a cover plate 150. The shell 130 is provided with a plug interface 131. The plug terminal 110 is arranged on the back of the shell 130 and corresponds to the plug interface 131. Two connecting parts 132 are arranged on the back of the shell 130 on two opposite sides of the plug interface 131. The two connecting parts 132 are respectively provided with a first sliding part 133 and a second sliding part 134. The cover plate 150 is arranged between the two connecting parts 132. The cover plate 150 has a first end 151 and a second end 152 that are arranged opposite to each other. A first matching part 153 is arranged at a position of the cover plate 150 close to the first end 151, and a second matching part 154 is arranged at a position of the cover plate 150 close to the second end 152. The first matching portion 153 is disposed on the first sliding portion 133 , and the second matching portion 154 is disposed on the second sliding portion 134 , so that the cover 150 can move relative to the housing 130 and rotate to open or close the plug-in port 131 .

[0067] In this embodiment, a plug-in port 131 is provided on the housing 130, and the plug-in terminal 110 is provided on the back of the housing 130 and corresponds to the plug-in port 131. Two connecting parts 132 are provided on the back of the housing 130 at the left and right sides of the plug-in port 131, and the first sliding part 133 and the second sliding part 134 are provided on the two connecting parts 132 respectively, and the cover plate 150 is provided between the two connecting parts 132, and the first matching part 153 is provided at the position of the cover plate 150 close to the first end 151, and the second matching part 154 is provided on the cover plate 150 close to the second end 152, and the first matching part 153 is provided on the first sliding part 133, and the second matching part 154 is provided on the second sliding part 134, so that the cover plate 150 can move relative to the housing 130 and rotate to open or close the plug-in port 131, so that the cover plate 150 combines translation and rotation during the opening process, thereby improving the problem that the cover plate 150 takes up a large space during the opening and closing process.

[0068] If the cover plate 150 is installed in the existing rotating manner, a large space needs to be reserved for the cover plate 150 to facilitate its rotation to open and close. In order to avoid interference between the plug-in terminal 110 and the cover plate 150 when flipping open, the terminal needs to be moved backward a large distance, so the length of the bracket needs to be lengthened. The most important thing is that the size of the plug-in interface device 100 in the thickness direction of the seat body backrest will increase significantly, and a large space needs to be reserved when installing the plug-in interface device 100 to the backrest of the seat body, and even the seat back needs to be thickened to achieve this. However, this embodiment can reduce the space occupied by the cover plate 150 when opening and closing by changing the installation method of the cover plate 150, so that the distance between the plug-in terminal 110 and the shell 130 can be closer, thereby reducing the volume and making it easier to install.

[0069] The housing 130 may be a back plate of the seat body backrest, or may be a separate shell structure mounted on the back plate of the seat body backrest by fasteners. In this embodiment, the housing 130 is a separate structure, which is mounted on the inner side of the seat back plate by screws, and the area of ​​the housing 130 corresponding to the plug interface 131 is exposed from the mounting opening of the back plate.

[0070] Please refer to Figures 1 to 8 In this embodiment, the two connecting parts 132 are respectively protruded on both sides of the first direction of the plug-in port 131. The first sliding part 133 is extended in the second direction, and the second sliding part 134 is extended in the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0071] In this embodiment, the first sliding portion 133 is extended in the second direction, and the second sliding portion 134 is extended in the third direction, so that the first end 151 that changes during the opening and closing process of the cover 150 slides along the second direction, and the second end 152 of the cover 150 slides along the third direction, so that the cover 150 can be translated and flipped when opened and closed, thereby saving space.

[0072] In this embodiment, the first direction is the left-right direction of the plug port 131, and the second direction is the up-down direction of the plug port 131. The third direction is the protruding direction of the connection portion 132, that is, the thickness direction of the shell. In this way, the cover 150 slides downward to open and slides upward to close.

[0073] In some other embodiments of the present application, the opening direction of the cover 150 can also be adjusted, for example, the cover 150 is slid upward to open, and slid downward to close. Alternatively, the cover 150 is slid to the left to open and to the right to close. Alternatively, the cover 150 is slid to the right to open and to the left to close. It is only necessary to adjust the setting positions of the two connecting parts 132, and when the opening direction of the cover 150 changes, the directions of the first direction, the second direction, and the third direction can be adaptively adjusted accordingly.

[0074] Please refer to Figures 1 to 8Furthermore, the shape of the plug-in port 131 is roughly rectangular, and the connecting portion 132 is two connecting plates arranged on the left and right sides of the plug-in port 131, and is integrally formed with the shell. The shape of the connecting portion 132 is roughly an "L" structure. The connecting portion 132 includes a vertical section and a horizontal section. The vertical section is connected to the back of the shell 130, while the horizontal section extends in a direction away from the back of the shell 130 and is located in the lower area of ​​the wiring terminal, so that it can form a avoidance with the wiring terminal, allowing the wiring terminal to be arranged closer to the shell 130. The first sliding portion 133 is arranged in the vertical section and extends in the vertical direction. The second sliding portion 134 is arranged in the horizontal section and extends in the horizontal direction, so that the second sliding portion 134 is located in the lower area of ​​the first sliding portion 133. When the cover 150 is opened from the closed position, the second end 152 of the cover 150 (i.e., the lower end of the cover 150) moves backward along the second sliding portion 134, and the first end 151 of the cover 150 (i.e., the upper end of the cover 150) moves downward along the first sliding portion 133, so that the cover 150 is tilted when it moves as a whole to open the plug-in port 131, and when the cover 150 is in the open position, the gravity of the cover 150 can keep the cover 150 in the open position, making it more convenient to plug in the bracket.

[0075] In this embodiment, the first sliding portion 133 is a first sliding groove 135 provided on the connecting portion 132, and the second sliding portion 134 is a second sliding groove 136 provided on the connecting portion 132. The first matching portion 153 is a first sliding shaft 155, and the second matching portion 154 is a second sliding shaft 156. The first sliding shaft 155 is installed in the first sliding groove 135, and the second sliding shaft 156 is installed in the second sliding groove 136; and the first sliding shaft 155 can move and rotate relative to the first sliding groove 135, and the second sliding shaft 156 can slide and rotate relative to the second sliding groove 136.

[0076] In this embodiment, the first sliding portion 133 is set as the first sliding groove 135, and the second sliding portion 134 is set as the second sliding groove 136, the first matching portion 153 is set on the first sliding shaft 155, and the second sliding portion 134 is set as the second sliding shaft 156. This structure is simple, easy to manufacture and install, with low cost and better stability.

[0077] Please refer to Figures 1 to 8Furthermore, first connection seats 157 are provided on both sides of the back side of the cover plate 150 near the first end 151, and second connection seats 158 are provided on both sides of the back side of the cover plate 150 near the second end 152. The first connection seats 157 are provided with first plug holes, and the second connection seats 158 are provided with second plug holes. There are two first sliding shafts 155, which are respectively inserted into the two first plug holes and extend into the first slide groove 135, so that the first sliding shaft 155 can slide in the extension direction of the first slide groove 135 and can rotate. The second sliding shaft 156 is a long shaft, which is inserted into the two second slide grooves 136 and the two second plug holes in a through manner. The first connection seat 157 and the second connection seat 158 ​​can also abut against the two connecting parts 132 to prevent the cover plate 150 from moving in the left and right directions.

[0078] In this embodiment, the first slide groove 135 has a first positioning side 137 and a second positioning side 138 in the length direction, the first positioning side 137 is the top of the first slide groove 135, and the second positioning side 138 is the bottom of the second slide groove 136. The second slide groove 136 has a first limiting side 139 and a second limiting side 141 in the length direction. The first limiting side 139 is the front end of the second slide groove 136, and the second limiting side 141 is the rear end of the second slide groove 136. When the cover plate 150 is in the closed position, the first sliding shaft 155 is close to the first positioning side 137, and the second sliding shaft 156 is close to the first limiting side 139. When the cover plate 150 is in the open position, the first sliding shaft 155 is close to the second positioning side 138, and the second sliding shaft 156 is close to the second limiting side 141. The position of the cover plate 150 relative to the housing 130 in the closed position and the open position can be adjusted by the positions of the two ends of the first slide groove 135 and the second slide groove 136. The first slide groove 135 bends and extends from the first positioning side 137 to the second positioning side 138 and toward the third direction. The second slide groove 136 bends and extends from the first limiting side 139 to the second limiting side 141 and toward the second direction.

[0079] In this embodiment, the first slide groove 135 is bent and extended from the first positioning side 137 to the second positioning side 138 in the third direction. The second slide groove 136 is bent and extended from the first limiting side 139 to the second limiting side 141 in the second direction, so that the cover plate 150 can gradually move away from the housing 130 during the opening process, thereby avoiding interference with the cover plate 150 when the cover plate 150 rotates, and making it more convenient to open and close the cover plate 150.

[0080] Specifically, the first slide groove 135 includes a first section 142 and a second section 143 connected in a smooth transition, the first section 142 is located in the upper area of ​​the first slide groove 135, and the second section 143 is located in the lower area of ​​the second slide groove 136. The first section 142 is inclined from top to bottom toward the plane where the plug-in port 131 is set away from the housing 130, and the second section 143 is parallel to the plane where the plug-in port 131 is set in the housing 130. The length of the first slide groove 135 corresponds to the size of the cover plate 150 in the up and down direction. The second slide groove 136 includes a third section 144 and a fourth section 145 connected in a smooth transition. The third section 144 is located at the front side of the second slide groove 136, and the fourth section 145 is located at the rear side of the second slide groove 136. The third section 144 is horizontally arranged and corresponds to the lower end of the plug-in port 131. The fourth section 145 is inclined downward in the direction away from the housing 130. When the cover 150 is in the closed position, the cover 150 is embedded in the plug-in port 131 , and the outer plane of the cover 150 and the outer plane of the shell 130 where the plug-in port 131 is arranged are substantially in the same plane, which is more aesthetically pleasing.

[0081] When the cover 150 moves from the closed position to the open position, first, the first sliding shaft 155 slides along the inclined first section 142 while the second sliding shaft 156 slides along the third section 144, so that the cover 150 can be removed from the plug-in notch and can also avoid interference between the cover 150 and the housing 130 when the cover 150 rotates. When the cover 150 moves from the open position to the closed position, when the second sliding shaft 156 slides to the third section 144, the cover 150 and the plug-in port 131 can be aligned. After the first sliding shaft 155 slides to the first section 142, it slides along the first section 142 to guide the cover 150 forward so that the cover 150 is engaged with the plug-in port 131.

[0082] On the whole, the setting of the first slide groove 135 and the second slide groove 136 can make it easier for the cover 150 to be inserted into the plug-in notch, so that when the cover 150 is in the closed position, the outer side surface of the cover 150 and the outer side surface of the plug-in interface 131 of the shell 130 are in the same plane, and the gap around the cover 150 and the side wall of the plug-in interface 131 are uniform, thereby making it more beautiful and having a better sealing effect.

[0083] Please refer to Figures 1 to 8 In this embodiment, a limiting protrusion 146 is provided on the side wall of the second slide groove 136 near the first limiting side 139. When the cover plate 150 moves from the open position to the closed position, the second sliding shaft 156 can pass over the limiting protrusion 146 and abut against the limiting protrusion 146 to limit the cover plate 150 to the closed position.

[0084] In this embodiment, a limiting protrusion 146 is disposed on the second sliding groove 136 , so that the second sliding shaft 156 can be clamped when the cover 150 is in a closed state, thereby preventing the cover 150 from being opened unintentionally.

[0085] Specifically, the limiting protrusion 146 is an arc-shaped boss, and is disposed on the side wall of the third section 144. The arc-shaped boss is more convenient for the second sliding shaft 156 to pass over during the movement to form a snap-fit ​​relationship.

[0086] Of course, in some other embodiments of the present application, the limiting protrusion 146 may also be disposed on the side wall of the first section 142 .

[0087] In this embodiment, an operating portion 159 is protruded from the outer side of the cover plate 150. When opening or closing the cover plate 150, the user can move the cover plate 150 through the operating portion 159 to conveniently open and close the cover plate 150.

[0088] In this embodiment, a limiting portion 161 is disposed on the periphery of the cover 150 . When the cover 150 is in the closed position, the limiting portion 161 abuts against the back surface of the housing, and the cover 150 is inserted into the plug port 131 .

[0089] Please refer to Figures 1 to 8 In this embodiment, the limiting portion 161 is arranged on the periphery of the cover plate 150, so that the limiting portion 161 can abut against the back of the housing 130 for limiting and sealing when the cover plate 150 is in the closed position. The thickness of the limiting portion 161 is less than the thickness of the entire cover plate 150, so as to ensure that the area of ​​the cover plate 150 corresponding to the front side wall of the limiting portion 161 can be inserted into the plug-in port 131. Generally, the thickness between the front of the cover plate 150 and the front side wall of the limiting portion 161 is the same as the wall thickness of the part of the housing 130 where the plug-in port 131 is arranged, so as to ensure that the cover plate 150 does not protrude from the front of the housing 130 after being inserted into the plug-in port 131 when the cover plate 150 is in the closed position.

[0090] In this embodiment, the plug interface device 100 further includes a linkage hinge 170, one end of which is hinged to the cover 150, and the other end of which is hinged to the connecting portion 132. When the cover 150 is opened or closed, the linkage hinge 170 can provide auxiliary thrust to the cover 150.

[0091] In this embodiment, a linkage hinge 170 is provided, and the linkage hinge 170 can be used to apply an auxiliary thrust to the cover plate 150, so that the cover plate 150 can be opened and closed conveniently.

[0092] Please refer to Figures 1 to 8In this embodiment, the linkage hinge 170 includes a first hinge block 171, a hinge shaft 172, a second hinge block 173 and a torsion spring 174. One end of the first hinge block 171 is hinged to one end of the second hinge block 173 through the hinge shaft 172. The torsion spring 174 is sleeved on the hinge shaft 172, and one end of the torsion spring 174 is connected to the first hinge block 171, and the other end is connected to the second hinge block 173. The other end of the first hinge block 171 is hinged to the cover plate 150, and the other end of the second hinge block 173 is hinged to the connecting portion 132. When the cover plate 150 moves between the open position and the closed position, the angle between the two ends of the torsion spring 174 gradually decreases and then gradually increases.

[0093] In this embodiment, the linkage hinge 170 is configured as the above-mentioned structure and installation method, and the deformation of the torsion spring 174 can be used to apply an auxiliary thrust to the cover plate 150, thereby facilitating the opening and closing of the cover plate 150.

[0094] Specifically, a first hinge hole is provided at one end of the first hinge block 171, and two first hinge ears are provided at intervals at the other end, and a second hinge hole is provided on each of the two first hinge ears. A third hinge hole is provided at one end of the second hinge block 173, and two second hinge ears are provided at intervals at the other end, and a fourth hinge hole is provided on each of the two second ears. The hinge shaft 172 is sequentially passed through the fourth hinge hole and the second hinge hole to hinge the two first hinge ears and the two second hinge ears. The two second hinge ears are respectively located on the outside of the two first hinge ears. The torsion spring 174 is sleeved on the hinge shaft 172 and is located in the interval between the two first hinge ears. A first clamping groove is provided on the inner side of the first hinge block 171, and a second clamping groove is provided on the inner side of the second hinge block 173. The two ends of the torsion spring 174 are respectively a first support arm 175 and a second support arm 176. The first support arm 175 is clamped in the first clamping groove, and the second support arm 176 is clamped in the second clamping groove. The first hinge block 171 rotates relative to the second hinge block 173 to increase or decrease the angle between the first support arm 175 and the second support arm 176. In other words, the torsion spring 174 can apply both elastic force and tensile force to the first hinge block 171 and the second hinge block 173.

[0095] The second sliding shaft 156 is inserted into the first hinge hole to hinge the first hinge block 171 with the cover plate 150. The two mounting portions are located in the upper area of ​​the second slide groove 136 and the corresponding rotation axis holes 162 are set. The rotation axis hole 162 is set near the front section of the fourth section 145. The third hinge hole is provided with two ends of the rotation axis 177, which are respectively inserted into the rotation axis holes 162. When the cover plate 150 moves, the first hinge block 171 and the second hinge block 173 will rotate relative to the hinge axis 172, and the second hinge block 173 will also rotate relative to the rotation axis 177.

[0096] When the cover 150 moves from the closed position to the open position, the angle between the first support arm 175 and the second support arm 176 of the torsion spring 174 also changes from large to small and then to large. In the process of changing the angle from large to small, it is necessary to provide an external force to push the cover 150 to open and allow the torsion spring 174 to store energy. When the angle changes from small to large, the torsion spring 174 will apply an outward auxiliary thrust to the first hinge block 171, so that the linkage hinge 170 pulls the cover 150 to open. In this process, the torsion spring 174 will apply an outward elastic force to the first hinge block 171 and the second hinge block 173 to assist the cover 150 to open. When the cover 150 is fully opened, the cover 150 relies on its own gravity to remain in the fully opened position. When the cover 150 is in the process of changing from opening to closing, the angle between the first support arm 175 and the second support arm 176 of the torsion spring 174 also changes from large to small and then to large. The specific process will not be repeated.

[0097] Please refer to Figures 1 to 8 In this embodiment, the plug-in terminal 110 is provided with a plug-in channel 111 of a plug-in bracket, and a side of the plug-in terminal 110 located in the second direction is provided with an escape space 112. When the cover 150 is in the open position, the plug-in channel 111 can be exposed to the plug-in port 131, and the cover 150 is partially accommodated in the escape space 112.

[0098] In this embodiment, an escape space 112 is provided on one side of the plug terminal 110 in the second direction, so as to facilitate the receiving of the cover plate 150 when it is opened. In this embodiment, the escape space 112 is located in the lower area of ​​the plug terminal 110.

[0099] In this embodiment, the plug-in terminal 110 includes a terminal body 113, an anti-dropout card 114 and a compression spring 115. The plug-in channel 111 is arranged on the terminal body 113, and the plug-in terminal 110 is provided with a conductive contact corresponding to the bracket. The side wall of the terminal body 113 is provided with a mounting hole 116 connected to the plug-in channel 111. The anti-dropout card 114 is arranged in the mounting hole 116, and the compression spring 115 is installed in the terminal body 113 and abuts against the outer side of the anti-dropout card 114. When the bracket is plugged into the plug-in channel 111, the anti-dropout card 114 can be snapped with the bracket. The compression spring 115 and the anti-dropout card 114 are arranged in this embodiment to prevent the bracket from falling out. A card slot is arranged at the position of the bracket corresponding to the anti-dropout card 114, and the anti-dropout card 114 can be snapped into the card slot under the action of the compression spring 115, and when the bracket is pulled outward by external force, the anti-dropout card 114 can be moved out of the card slot.

[0100] It should be noted that this embodiment only illustrates an implementation method in which the cover plate 150 is opened downward. In other embodiments of the present application, the cover plate 150 can also be opened upward, leftward or rightward, which can be achieved by changing the setting direction of the connecting portion 132. The first sliding portion 133 and the second sliding portion 134 can also be slide rails or other structures with a sliding guide function.

[0101] In summary, in this embodiment, the housing 130 is provided with a plug-in port 131 , and the plug-in terminal 110 is disposed on the back side of the housing 130 and corresponds to the plug-in port 131 . Two connecting parts 132 are arranged on the left and right sides of the plug interface 131 on the back side of the shell 130, and the first sliding part 133 and the second sliding part 134 are correspondingly arranged on the two connecting parts 132, and the cover 150 is arranged between the two connecting parts 132, and the first matching part 153 is arranged at the position of the cover 150 close to the first end 151, and the second matching part 154 is arranged on the cover 150 close to the second end 152, the first matching part 153 is arranged on the first sliding part 133, and the second matching part 154 is arranged on the second sliding part 134, so that the cover 150 can move relative to the shell 130 and rotate to open or close the plug interface 131, so that the cover 150 combines translation and rotation movements during the opening process, thereby improving the problem that the cover 150 occupies a large avoidance space 112 during the opening and closing process.

[0102] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
