[0002] In the existing field of vehicle interior decoration, seats generally include headrests to facilitate the driver or passengers to sit. However, the space inside the car is relatively small and compact. In order to further utilize the limited space, a storage space can be set in the seat headrest to store the required items. In the existing technology with storage space, such as Chinese patent CN201510282103.6, the headrest body and the sealing cover are connected and closed by a push-type elastic lock. When the push-type elastic lock is pressed, the sealing cover opens to expose the storage space. However, the above-mentioned scheme of connecting the headrest body and the sealing cover by mechanical connection methods such as elastic locks, once the mechanical connection is damaged, it makes the sealing cover difficult to open, and the storage space cannot be used. In addition, the items stored in the storage space described in the prior art are not fixed, and any scattered items of suitable volume can be placed in the storage space, which makes the storage space relatively messy.

[0003] Therefore, in order to solve the above problems, the present invention provides a seat headrest and a seat including the seat headrest, using a driver to drive the opening and closing of the seat headrest, and placing the required fixed items in the storage space, and extending the fixed items from the storage space when needed.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0034] like Figure 1A seat is shown, which includes a seat headrest 1 and a seat body 2. The seat headrest 1 includes: a headrest body 3, a headrest sub-component 4, a storage space 5 and a driver. The headrest body 3 and the headrest sub-component 4 are combined to form the storage space 5. The headrest body 3 is located at the front part of the headrest, and the headrest sub-component 4 is located at the rear part of the headrest. The storage space formed by the combination has an opening. The opening is located at the top or side of the headrest body. A storage cover (not shown in the figure) is provided at the opening. The storage cover can cover the opening in the first mode and can be opened upward or to the side in the second mode.

[0035] The seat headrest 1 also includes a cover driver connected to the storage cover to drive the storage cover to move relative to the headrest body; in the first mode, the storage cover is located in a closed position, and in the second mode, the storage cover is located in an open position. Figure 1 The headrest body 3 is shown as the front half of the seat headrest 1, and the headrest sub-component 4 is the rear half of the seat headrest 1. The positions of the two can be changed as needed, that is, the headrest sub-component 4 is set as the front half of the seat headrest 1, and the headrest body 3 is set as the rear half of the seat headrest 1. Figure 2 and 3 As shown, the seat headrest 1 further includes at least one telescopic mechanism 6, which is stored in the storage space 5 in the first mode and extends from the storage space 5 in the second mode. A driver can make the telescopic mechanism move between the first and second modes. An applied load 7 is fixedly connected to the front end of the telescopic mechanism 6. When the telescopic mechanism 6 extends from the storage space 5, it avoids obstacles (such as Figure 3 The middle circle shows the head of a user sitting on the seat) so that the applied load 7 is located in front of the user of the seat headrest 1.

[0036] The structure of the telescopic mechanism 6 is described in detail below. Figure 4-7 As shown, it includes: a main arm 8, which has an outer side and an inner side; an outer arm 9, which has an outer arm end 13; an inner arm 10, which has an inner arm end 14; the outer arm 9 is slidably connected to the main arm 8 on the outer side, and the inner arm 10 is slidably connected to the main arm 8 on the inner side; a driving motor 11; a transmission belt 12, which is arranged in the main arm 8 and connected to the driving motor 11, and the transmission belt 12 is connected to the outer arm end 13 of the outer arm 9 and to the inner arm end 14 of the inner arm 10.

[0037] The main arm 8 includes a main body 15 and a cover 16, which are connected by screw connection, interlocking connection or other detachable connection methods, and there is a storage space inside the main body 15. A transmission belt movement limiting part 17 is arranged in the middle of the main body 15, and a driving motor 11 is arranged at one end of the limiting part 17, which can also be selected as other driving and rotating devices. The surface of the driving motor 11 can be provided with a toothed part that matches the inner surface of the transmission belt 12; the other end of the limiting part 17 is provided with a transmission belt sleeve part 18, and the transmission belt sleeve part 18 can be selected as a gear that rotates synchronously with the driving motor 11 or an ordinary fixed end. In this way, the transmission belt 12 is sleeved onto the driving motor 11 and the transmission belt sleeve part 18, and the movement track of the transmission belt 12 is jointly limited by the middle transmission belt movement limiting part 17 and the outer arm 9, the inner arm 10 and the main arm 8. When the driving motor 11 rotates, the teeth on the surface of the driving motor 11 and / or the teeth on the surface of the transmission belt sleeve 18 (when a gear that rotates synchronously with the driving motor is selected) mesh with the teeth on the inner surface of the transmission belt 12, driving the transmission belt 12 to rotate, so that the outer arm 9 and the inner arm 10 move in opposite directions. The present invention is driven by a single driving motor, which reduces the complexity of the extension device.

[0038] The length of the outer arm 9 is equivalent to that of the main arm 8. The outer arm end 13 is located at one end of the outer arm 9. The outer arm 9 is fixedly connected to the transmission belt 12 through the outer arm end 13, so that the outer arm 9 moves with the movement of the transmission belt 12. The fixed connection can be a snap connection, a sleeve connection, or other fixed connection methods. In addition, the outer arm 9 is slidably connected to the main arm 8. The sliding connection can be achieved by setting a groove and a guide rail at the corresponding matching positions of the outer arm 9 and the main arm 8. The inner arm 10 is shorter in length and is fixedly connected to the transmission belt 12 through the inner arm end 14, so that the inner arm 10 moves with the movement of the transmission belt 12. The fixed connection can be a snap connection, a sleeve connection, or other fixed connection methods. In addition, the inner arm 10 is slidably connected to the main arm 8. The sliding connection can be achieved by setting a groove and a guide rail at the corresponding matching positions of the inner arm 10 and the main arm 8.

[0039] The outer arm 9 slides along the outer side of the main arm 8, and the outer side has an outer starting end 19 and an outer terminal 20; the outer arm 9 moves between the outer starting end 19 and the outer terminal 20; the inner arm 10 slides along the inner side of the main arm 8, and the inner side has an inner starting end 21 and an inner terminal 22; the inner arm 10 moves between the inner starting end 21 and the inner terminal 22. The outer starting end 19, the outer terminal 20, the inner starting end 21, and the inner terminal 22 are located at the two ends of the main arm 8, and the outer starting end 19 is on different sides from the inner starting end 21, that is, they are respectively located at the two ends of the main arm 8, and the outer terminal 20 and the inner terminal 22 are also located at the two ends of the main arm 8. The telescopic mechanism 6 of the present invention adopts the above-mentioned two-dimensional movement, which further reduces the complexity of the structure and facilitates manufacturing.

[0040] like Figure 4 As shown, a load fixing portion 23 is provided at one end of the outer arm 9 extending outward, and the load fixing portion 23 is used to fix the application load 7 expected to be carried by the telescopic mechanism 6. Figure 4 The application load 7 shown in the figure is an optical lens, and the application load 7 can be replaced according to the needs of different application occasions. Figure 4 The load fixing part 23 is only schematically listed in the figure, and its specific shape and structure can be adaptively changed according to the application load 7 carried. The inner arm 10 is provided with an application connection part 24 connected to an application device (not shown) on the other side of the inner arm end 14, that is, the side away from the main arm 8, for fixing the telescopic mechanism 6 to the application device. The application connection part 24 is Figure 4 The schematic diagram is a gear, and other convenient connection structures can also be used. On the other hand, the load fixing part 23 can be set on the side of the inner arm 10 facing the inner terminal 22, and the application connection part 24 can be set at the position of the outer arm 9 facing the outer terminal 20 and away from the outer arm end 13.

[0041] The telescopic mechanism 6 also includes a control switch, which is electrically connected to the drive motor 11 and is used to control the forward and reverse rotation of the drive motor 11, that is, to control the extension and retraction movement of the telescopic mechanism 6. The control switch can be set on the application device or other convenient locations. The control switch can also control the opening and closing of the storage cover 4 at the same time, so that when the storage cover 4 is opened, the telescopic mechanism 6 extends from the storage space 5 to the front of the seat headrest 1.

[0042] like Figure 5 As shown, the load fixing portion 23 can be rotated at a certain angle according to the action of the control switch, so that it can be unfolded when the telescopic mechanism 6 is extended and folded when it is retracted, so as to reduce the occupied storage space 5.

[0043] The telescopic process of the telescopic mechanism 6 is described as follows: In the initial state of the telescopic mechanism 6, all components are in a retracted state, such as Figure 6As shown. At this time, the outer arm end 13 of the outer arm 9 is located at the outer starting end 19, and the outer arm 9 basically overlaps with the main arm 8; the inner arm end 14 of the inner arm 10 is located at the inner starting end 21, and the entire telescopic mechanism 6 is in a retracted state relative to the application device, and is fixedly connected to the application device through the application connection part 24. When the telescopic mechanism 6 needs to be used, the user presses the control switch button, the drive motor 11 starts to rotate, and the motor drives the transmission belt 12 to move, which is counterclockwise in the figure, then the inner arm 10 moves from the inner starting end 21 to the inner terminal 22, and the outer arm 9 moves from the outer starting end 19 to the outer terminal 20; the main arm 8 extends outwardly in the direction away from the application device relative to the inner arm 10, and the outer arm 9 extends outwardly in the direction away from the application device relative to the main arm 8. When the fully extended state is reached, one end of the load fixing part 23 extends the length of the outer arm 9 + the main arm 8 relative to the application device, which is equivalent to the length of the two main arms. When the control switch is pressed again (or the control switch has different buttons to control different driving directions of the drive motor 11), the drive motor 11 rotates in the opposite direction, that is, clockwise, and the main arm 8 and the outer arm 9 move toward the direction approaching the application device relative to the inner arm 10 until they are retracted to or close to the application device.

[0044] Conductive components are provided on the outside and inside of the main arm 8, and conductive components are also provided on the side surfaces of the inner arm 10 and the outer arm 9 that are in contact with the main arm 8, so that the inner arm 10 and the outer arm 9 remain energized when they slide relatively on the main arm 8. The conductive components can be specifically provided by coating the side surfaces of the main arm 8, the outer arm 9 and the inner arm 10 that are in contact with each other with conductive materials, or by coating the contact side surfaces of the main arm 8 with conductive materials, and fixing conductive sheets or conductive wires on the corresponding contact surfaces of the outer arm 9 and the inner arm 10, so that the inner arm 10 and the outer arm 9 remain energized when they slide relatively on the main arm 8. In this way, if the application load 7 carried by the telescopic mechanism 6 is an electronic component or requires a current signal, the current signal can be transmitted to the carried application load 7 through the inner arm 10, the main arm 8 and the outer arm 9. The current signal is provided by connecting the application connection part 24 to a power source.

[0045] The application load 7 can be selected as an optical element, communication equipment, display, and / or a device with a camera or video recording function; the optical element can be a lens or glasses, including a reflector, a concave lens, a convex lens or a mirror, or a lens with a magnifying effect, through which the user can see a virtual image. The communication equipment can be an earphone, a speaker and / or a microphone, which is convenient for the user to use when communicating with the outside world; the device with a camera or video recording function can be a camera or a mobile phone, which is convenient for the user to use when recording the image in front of the seat.

[0046] In addition, a sound system may be fixedly placed in the storage space 5 to facilitate the user to listen to music or other audio information during the ride.

[0047] Another aspect of the present invention provides a seat, including a seat body 2 and a seat headrest 1 as described above. The seat can be fixedly installed on a motor vehicle, and of course, can also be used in the furniture field or other application occasions where required.

[0048] In summary, the present invention provides a seat headrest, comprising: a headrest body, a driver, a headrest sub-component and a storage space, wherein the headrest body and the headrest sub-component are combined to form the storage space; further comprising at least one telescopic mechanism, which is stored in the storage space in a first mode and extends from the storage space in a second mode, wherein the driver can enable the telescopic mechanism to move between the first and second modes; one end of the telescopic mechanism is connected to an applied load, and when the telescopic mechanism extends from the storage space, the applied load is located in front of the seat headrest. The present invention also provides a seat including the above-mentioned seat headrest. The present invention places and fixes the required items in the storage space, and controls the items to extend from the storage space when in use, without manual extension and retraction, and is convenient to operate; and uses a driver to drive the closing and opening of the storage cover, so that the closing and opening control of the storage space is reliable and convenient.
