Technical Field

[0001] This utility model relates to a control box and a movable seat unit for a movable seat. Background Technology

[0002] As people's living standards improve, their demands for the comfort and ease of use of sofas and chairs are also constantly increasing. In known designs, movable seating units often integrate multiple functions, such as charging, music playback, and infrared seat heating. However, controlling these functions requires multiple separate control devices. This not only increases the cumbersome steps of retrieving these control devices but also occupies a significant amount of storage space. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a movable seat with more complete control functions and more convenient operation.

[0004] To solve the above-mentioned technical problems, this utility model provides a control box for a movable seat, the control box comprising:

[0005] A base unit mounted on the movable seat;

[0006] A screen unit with a touch screen, the screen unit being pivotally connected relative to the base unit by means of a pivot axis fixedly connected to the base unit;

[0007] A wireless charging unit fixedly arranged relative to the base unit;

[0008] At least one control element mounted on the base unit; and

[0009] An electro-actuating device for driving the pivoting of the screen unit, the electro-actuating device being designed to cause the screen unit to change between an initial position and a flip position, in which the screen unit is against the base unit, and in the flip position, one end of the screen unit is raised relative to the base unit.

[0010] The electro-actuated device includes an anti-pinch mechanism that acts between the screen unit and the electro-actuated device, thereby preventing the screen unit from resetting from the flipped position to the initial position.

[0011] According to this invention, the screen unit is rotatably mounted in the base unit. When in its initial position, the control box has a compact overall structure. When in its flipped position, the screen unit is positioned at an angle that is more conducive to the user's viewing of information and input operations, improving ease of use and comfort. Furthermore, an anti-pinch mechanism is provided for the electro-actuated device. Therefore, during the process of the screen unit returning from the flipped position to the initial position, if it comes into contact with a foreign object or even the user's hand, the downward flipping and resetting action of the screen unit is immediately stopped, thus preventing foreign objects from damaging the control box or causing pinching injuries to the user's hand.

[0012] According to a preferred embodiment of the present invention, the anti-pinch mechanism includes a first clutch portion, a second clutch portion, a drive bracket, and a clutch spring sleeved on the pivot shaft. The first clutch portion is torsionally fixedly connected to the screen unit, and the second clutch portion is torsionally fixedly connected to the drive bracket. The drive bracket can pivot around the pivot shaft under the drive of an electric actuator. The clutch spring can press the second clutch portion relative to the first clutch portion, thereby establishing or releasing torque transmission between the first clutch portion and the second clutch portion.

[0013] According to a preferred embodiment of the present invention, the clutch spring is constructed as a helical spring sleeved on the second clutch portion, wherein one end of the helical spring is connected to the second clutch portion and the other end is connected to the drive bracket.

[0014] According to a preferred embodiment of the present invention, when the screen unit encounters resistance during the process of resetting from the flipped position to the initial position, the clutch spring is compressed to allow the second clutch portion to rotate relative to the first clutch portion, thereby releasing the torque transmission between the first clutch portion and the second clutch portion.

[0015] By employing a clutch spring, reliable torque engagement can be achieved in a simple manner. When there are no foreign objects or the user's hand between the screen unit and the base unit, the screen unit is not subjected to additional external forces. The clutch spring always keeps the second clutch portion pressed against the first clutch portion, thereby transmitting the torque provided by the electro-actuator to the screen unit through the second and first clutch portions. However, when there are foreign objects or the user's hand between the screen unit and the base unit, the screen unit is subjected to external forces. In this case, the second clutch portion overcomes the spring force of the clutch spring and rotates relative to the first clutch portion, releasing the torque transmission between the first and second clutch portions, thus preventing the screen unit from continuing to pivot and reset.

[0016] According to a preferred embodiment of the present invention, the screen unit includes a screen bracket for supporting the touch screen, and the screen unit is fixedly connected to the first clutch portion by means of the screen bracket.

[0017] According to a preferred embodiment of the present invention, one end of the electric actuator is connected to the base unit and the other end is connected to the drive bracket.

[0018] According to a preferred embodiment of the present invention, the drive bracket includes a connector with an elongated hole, wherein the electric actuation device is configured as a linear actuator including a motor head and an actuating rod retractable relative to the motor head, the motor head being fixedly connected to the base unit, and the free end of the actuating rod including a locking pin that is slidably engaged in the elongated hole of the connector.

[0019] According to a preferred embodiment of the present invention, the touch screen is configured as a human-computer interaction interface and includes at least one input element that can be operated by the user.

[0020] According to a preferred embodiment of the present invention, the input element is at least used to control the posture changes of the movable seat.

[0021] According to a preferred embodiment of the present invention, the control element is constructed as a rotary control knob.

[0022] According to a preferred embodiment of the present invention, the control element is used to control the playback of audio.

[0023] According to a preferred embodiment of the present invention, the base unit is constructed to be recessed downward in the region belonging to the wireless charging unit.

[0024] This utility model also provides a movable seat unit, which includes the control box described above.

[0025] According to a preferred embodiment of the present invention, the seat unit includes at least one seat portion and an armrest portion, wherein the control box is fitted into the armrest portion.

[0026] According to a preferred embodiment of the present invention, the seat unit includes at least one seat and a backrest, wherein the control box is rotatably mounted in the backrest.

[0027] According to a preferred embodiment of the present invention, the seat unit includes at least two seats and a shelf arranged between the seats, wherein the control box is fitted into the shelf.

[0028] According to a preferred embodiment of the present invention, the seat unit further integrates one or more of the following modules: a Bluetooth connection module; a voice input module; a lighting module; a cup holder module; a massage airbag module; a sound module; a vibration module; and a drive unit for causing the seat unit to change posture.

[0041] Figures 1 to 3 The movable seat unit 1000 according to the present invention is schematically shown. The seat unit 1000 may include a seat 200, a backrest 300, a leg rest 400, and is configured to be able to switch between a sitting position, a TV position, and / or a reclining position.

[0042] In such Figure 1 In the illustrated embodiment, the seating unit 1000 is designed for two people, comprising two side-by-side seats 200 and a backrest 300 and a leg rest 400 corresponding to each seat 200. A table 500 serving as a coffee table is also provided between the two seats 200, on which a control box 100 is fitted. Figure 2 As shown, the shelf 500 also integrates two cup holder modules 72. Particularly preferably, the cup holder module 72 is equipped with a heater or a cooler to heat or cool the beverage.

[0043] In an embodiment not shown, the control box 100 may also be fitted into the armrest portion 600.

[0044] In another embodiment, not shown, the backrest may include a downward-folding mounting bracket in which the control box 100 is disposed. In this case, when the mounting bracket is folded into the backrest, it is substantially flush with the surface of the backrest facing the user, and the control box 100 is concealed within the backrest and thus not visible from the outside; while when the mounting bracket is folded down, the control box 100 is exposed for user operation.

[0045] In such Figure 3 In the illustrated embodiment, the seat unit 1000 is designed as a single-seat unit. Optionally, one or more of the following functional modules may be integrated into the seat unit 1000: a Bluetooth connectivity module; a voice input module; an illumination module 71 configured as a light strip; a cup holder module 72; one or more massage airbag modules 73; an audio module 74; a vibration module 75; and a drive unit 76 for inducing posture changes in the seat unit. The massage airbag module 73 can be selectively arranged in the seat 200, backrest 300, headrest associated with the backrest, leg rest 400, or armrest 600, depending on the specific product design. The audio module 74 may include a full-range speaker or tweeter 741 and / or woofer 742. It should be noted that if a woofer 742 is provided, it should be exposed to ensure good sound quality. The vibration module 75 is configured to generate corresponding vibrations in response to audio playback and may be installed in the seat 200 or backrest 300 as needed. The drive unit 76 may be configured as one or more linear motors. Depending on the product design requirements, the drive unit 76 can be designed to facilitate the movement of the seat, backrest, and / or leg rest to enable the seat unit to change between different postures.

[0046] Accordingly, depending on the different functional modules equipped in the seat unit, the control box 100 can be designed to control one or more of the following functional modules: Bluetooth connection module; voice input module; lighting module 71 configured as a light strip; cup holder module 72; one or more massage airbag modules 73; audio module 74; vibration module 75; and drive unit 76 for causing the seat unit to change posture.

[0047] However, in any case, the control box 100 according to this utility model can at least realize the control of the audio module 74 and the drive unit 76.

[0048] In such Figure 4 and Figure 5 In the embodiment shown, the base unit 1 includes an upper base 11 and a lower base 12, wherein the upper base 11 and the lower base 12 are fixedly connected, thereby forming a receiving space between the upper base 11 and the lower base 12, and the main control circuit board 13 of the control box 100 is arranged in the receiving space.

[0049] The base unit 1 can be divided into multiple regions according to function. Accordingly, the lower part 12 of the base has a bottom surface that generally extends along a plane, while the upper part 11 of the base is constructed in a stepped manner to meet various functional needs. For example, in this embodiment, the upper part 11 of the base includes a screen area 11a, an audio control area 11b, and a charging area 11c arranged adjacent to each other. The screen area 11a and the charging area 11c are respectively recessed downwards, while the audio control area 11b is arranged between the screen area 11a and the charging area 11c and is constructed as a slope inclined towards the charging area 11c.

[0050] The screen unit 2 is pivotally mounted in the screen area 11a and can be switched between an initial position and a flipped position as needed. In the initial position, the screen unit 2 rests against the base unit 1 as a whole, thus extending substantially parallel to the bottom surface of the base unit 1; in the flipped position, the screen unit 2 pivots upward with its upper end, thereby flipping up relative to the base unit 1 to facilitate the user's viewing of information and implementation of control operations.

[0051] In this embodiment, the screen unit 2 includes a screen bracket 21, a touch screen 22, and a screen circuit board 23 for the screen unit 2. In particular, as shown in... Figures 5 to 7 As shown, the screen bracket 21 includes a frame-like main bracket 21a and a plate-like lower bracket 21b with a fixing tab 21'. The edges of the main bracket 21a and the lower bracket 21b are fixedly connected, thereby clamping and fixing the screen circuit board 23 between the main bracket 21a and the lower bracket 21b. The screen circuit board 23 includes a flexible circuit board for realizing electrical and signal connections between the screen unit 2 and other components of the control box 100. The touch screen 22 is arranged on the top side of the main bracket 21a of the screen bracket 21, and a screen cover layer 22' is arranged on the touch screen 22. When the touch screen 22 is triggered and activated, it can display information to the user. Multiple input elements (not specifically illustrated) are provided on the touch screen 22 for the user to perform control operations. The input elements may be, for example, symbols of various components of the seat unit shown in icon form, such as the seat, backrest, leg rest, or headrest. When the user touches one of the input elements, the component of the seat unit corresponding to that input element moves under the action of the drive unit 76. This controls the posture changes of the seat unit. Of course, the input element can also represent a preset posture mode, such as a sitting posture, a TV posture, or a reclining posture. For example, when the user touches the input element representing a sitting posture, the seat unit directly changes to a sitting position with the backrest upright and the leg rest folded in. Alternatively, the screen unit 2 also includes a speaker 23 arranged in the base unit 1.

[0052] Two pivot brackets 15 are also fixed in the base unit 10, and the pivot shaft 14 passes through the pivot brackets 15. The screen unit 2 is pivotally connected to the base unit 1 via the pivot shaft 14 fixedly connected to the base unit 1. During the process of the screen unit 2 returning from the flipped position to the initial position, it may come into contact with foreign objects or even the user's hand. To prevent foreign objects from damaging the control box or causing pinching injuries to the user's hand, the electro-actuator 5 is equipped with an anti-pinch mechanism 6. The anti-pinch mechanism 6 includes a first clutch part 61, a second clutch part 62, a drive bracket 63, and a clutch spring 64, which are sleeved on the pivot shaft 14. In this embodiment, the first clutch part 61 and the second clutch part 62 include mutually adapted teeth. When the first clutch part 61 and the second clutch part 62 are engaged, torque transmission can be established; when the first clutch part 61 and the second clutch part 62 are decoupled, torque transmission is released. The pivot bracket 15 is fixedly connected between the first clutch portion 61 and the fixing piece 21' of the screen unit 2, thereby providing a torsion-resistant fixed connection between the first clutch portion 61 and the screen unit 2. The second clutch portion 62 is cylindrically constructed and includes a non-circular cross-section. Correspondingly, the drive bracket 63 includes a through hole adapted to the cross-section of the second clutch portion 62, thereby achieving a torsion-resistant fixed connection between the second clutch portion 62 and the drive bracket 63. The clutch spring 64 is constructed as a helical spring fitted onto the second clutch portion 62, wherein one end of the helical spring is connected to the second clutch portion 62 and the other end is connected to the drive bracket 63. The clutch spring 64 presses the second clutch portion 62 relative to the first clutch portion 61.

[0053] The drive bracket 63 also includes a connector 63' with an elongated hole. In this embodiment, the electro-actuating device 5 is configured as a linear actuator and includes a motor head 51 and an actuating rod 52 that is retractable relative to the motor head 51. The motor head 51 is fixedly connected to the base unit 1, and the free end of the actuating rod 52 includes a locking pin 53 that is slidably engaged in the elongated hole of the connector 63'. Thus, when the actuating rod 52 of the electro-actuating device 5 extends or retracts relative to the motor head 51, it causes the drive bracket 63 to pivot about the rotation axis 14, thereby driving the screen unit 2 to pivot about the rotation axis 14 between an initial position and a flip position.

[0054] During the process of screen unit 2 returning to its initial position from the flipped position, when there are no foreign objects or the user's hand between screen unit 2 and base unit 1, screen unit 2 will not be subjected to additional external forces. Since the clutch spring 64 always presses the second clutch part 62 relative to the first clutch part 61 and engages with it, the torque provided by the electro-actuator 5 is transmitted to screen unit 2 through the second clutch part 62 and the first clutch part 61. However, when there are foreign objects or the user's hand between screen unit 2 and base unit 1, screen unit 2 is subjected to external forces and cannot continue to pivot. At this time, the second clutch part 62 overcomes the spring force of the clutch spring 64 and rotates relative to the first clutch part 61 to release the torque transmission between the first clutch part 61 and the second clutch part 62, thereby preventing screen unit 2 from continuing to pivot and return to its initial position.

[0055] The audio control area 11b provides multiple control elements 4 for controlling audio playback. These control elements 4 can be configured as rotary knobs or buttons. In this embodiment, four control elements 4 are provided, respectively controlling the vibration intensity and volume of the full-range speaker or tweeter 741, woofer 742, and vibration unit 75. Furthermore, the audio control area 11b is not limited to arranging the control elements 4 for controlling audio playback. In fact, other functional interfaces can also be provided in the audio control area 11b, such as a Bluetooth control element 4a for controlling the Bluetooth module, a Type-C interface 4b, a microphone 4c for receiving voice commands, and a USB interface 4d.

[0056] Below the upper part 1a of the base unit 1, a knob circuit board 40 for the control element 4 and a backlight device 41 arranged on the knob circuit board 40 are also arranged. The knob circuit board 40 is designed to process input signals from the control element 4 and other control elements mentioned above, such as the Bluetooth control element 4a, and to send output signals to the corresponding functional units. The backlight device 41 is positioned opposite to the control element 4 to emit light when the control element 4 is operated, as visual feedback to the user's operation.

[0057] A wireless charging unit 3 is arranged in the charging area 11c. In this embodiment, two wireless charging units 3 are provided, thereby enabling simultaneous charging of two electronic devices. Figure 4 and Figure 5As shown, the wireless charging unit 3 is arranged side-by-side in the charging area 11c between the upper base 11 and the lower base 12 of the base unit 1. The charging area 11c is recessed and has a relatively large flat surface so that electronic devices such as mobile phones can be placed flat in the charging area 11c. When charging is not required, the charging area 11c can also be used as a regular storage space. The recessed design also prevents items placed in this area from accidentally falling out.
