Description

Mounting rack for vehicle seat display screen

Technical Field

The present disclosure relates generally to the field of vehicle seats, and more particularly to mounts for vehicle seat display screens.

Background

Under the background of the vigorous development of new energy vehicles, vehicle seats are gradually being electrically, intelligently and digitally implemented. As a main carrier of human-computer interaction, a vehicle seat display screen becomes an increasingly important configuration for embodying high-end performance of a vehicle. Therefore, how to improve the use feeling of the display screen becomes an important development direction.

The mounting structure of the vehicle seat display screen mainly has two practical schemes. One solution is to embed the display screen in a pit of the chair back plate, fasten the display screen to the chair framework by screws, and finally mount a cover on the surface for structural shielding. The other scheme is that a hole is formed in the chair back plate, the mounting support extends out of the hole to be mounted with the display screen, and then the upper cover and the lower cover are used for shielding. The two design schemes can not realize synchronous extension and pivoting of the display screen, so that the use comfort of consumers is weakened, and the luxury and the technological sense of the vehicle seat are reduced.

At present, some designs also provide the concept of utilizing an electric telescopic rod to stretch and retract a display screen and utilizing steel balls to rotate the display screen. However, this concept lacks a shield that moves with the display screen, thereby exposing the telescoping and rotating members to the external environment. This not only makes the telescoping and rotating members susceptible to and damaged by dust or foreign intrusions, but also makes the occupant susceptible to pinching by the telescoping and rotating members. In addition, the rider can see the telescopic member and the rotating member directly, and the attractiveness of the mounting rack is reduced.

The unlocking block 343 is used to urge the two stop sliders 24 laterally away from each other.

The attachment post 342 includes two or more resilient fingers 344 (2 are shown) projecting upwardly from the bottom thereof, and each resilient finger 344 is provided at its upper end with an outwardly projecting protrusion 345. Accordingly, the through-hole 314 of the cartridge body 313 has a radial dimension smaller than the protrusion 345 but larger than the resilient fingers 344. The connection column 342 passes through the through-hole 314 by the radially inward deformation of the resilient fingers 344, after which the resilient fingers 344 resume their original shape, so that the connection column 342 is connected to the through-hole 314 movably up and down by the protrusions 345.

The unlocking piece 343 includes inclined surfaces provided at both left and right ends of an upper surface thereof. Accordingly, the opening 315 of the case 313 has a radial dimension greater than that of the unlocking block 343, so that the unlocking block 343 can freely pass up and down through the opening 315. The two sloped surfaces of the unlocking block 343 can contact the slider legs 242 of the two stop sliders 24 and urge the two stop sliders 24 to move laterally away from each other as shown in fig. 11B.

The stop release button 34 also includes one or more button return springs 346 (2 shown). A button return spring 346 is provided between the base 341 and the top wall of the case 313. The button return spring 346 serves to bias the stopper release button 34 to its non-depressed position in which the protrusion 345 of the connecting post 342 abuts against the periphery of the through hole 314 of the case 313 and the unlocking piece 343 is located below the opening 315 of the case 313. When the occupant presses the base 341 of the stop release button 34 upward through the opening 317 of the case 313, the base 341 moves upward from the un-pressed position to the pressed position against the biasing action of the button return spring 346. As shown in fig. 11B, in the pressed position, the protrusion 345 of the connection post 342 is away from the through hole 314 of the case 313, and the unlocking piece 343 passes through the opening 315 of the case 313 and contacts and pushes the slider legs 242 of the two stopper sliders 24 to move laterally away from each other, thereby releasing the stopper of the slide holder 22 on the support plate 211.

Fig. 12A and 12B show an assembled perspective view and an enlarged view of the sliding cover 32 and the pivoting cover 33, respectively, fig. 13 shows an individual perspective view of the sliding cover 32, and fig. 14 shows an individual perspective view of the pivoting cover 33. As shown, the pivoting cover 33 may be nested within the sliding cover 32 and may be pivotally connected to the sliding cover 32.

The slide cover 32 includes a front cover body 321 and a rear cover body 322 connected to each other, and the front cover body 321 has a smaller outer size than the rear cover body 322. The front side cover 321 is generally square-shaped in cross section and includes a top wall, a bottom wall, and left and right side walls connected to each other. The front side cover 321 is opened in a longitudinal direction to pass the support bracket 21 and the sliding bracket 22 therethrough. The inner surfaces of the left and right side walls of the front cover 321 are provided with fixing recesses 329 to receive the fixing protrusions 229 of the slide bracket 22, thereby removably fixing the front cover 321 to the slide bracket 22. The front cover 321 may be received inside the fixed cover 31. The bottom surface of the front cover 321 is provided with slide rails 326, and the number and the positions of the slide rails 326 correspond to those of the slide rails 316 on the fixed cover 31. The sliding cover 32 can slide back and forth longitudinally within the fixed cover 31 by the sliding engagement of the slide 326 and the slide rail 316.

The rear cover body 322 is generally square-shaped in cross section and includes a top wall, a bottom wall, and left and right side walls connected to each other. The top wall, bottom wall, and left and right side walls of the rear cover body 322 are connected to the top wall, bottom wall, and left and right side walls of the front cover body 321, respectively. The rear cover body 322 is open in the longitudinal direction. The rear cover body 322 receives the pivot cover 33 therein. The rear cover body 322 is provided on its left and right side walls with two or more projections 324, upper and lower, respectively, for the pivoting cover 33 to pivot about a lateral pivot axis in the rear cover body 322.

The pivoting cover 33 is substantially square in cross section and includes a top wall, a bottom wall, and left and right side walls connected to each other. The pivot cover 33 is open in the longitudinal direction. The pivoting cover 33 is provided with two or more arc-shaped grooves 334 vertically aligned on the left and right sidewalls thereof, respectively. The number and location of the grooves 334 correspond to the protrusions 324 of the sliding cover 32. The groove 334 provides an arcuate path for the protrusion 324 to travel in so that the pivoting cover 33 can pivot about a lateral pivot axis within the sliding cover 32 to conceal the connection and pivoting portion between the display screen 8 and the sliding bracket 22. In other embodiments, the protrusions 324 and the grooves 334 may be oppositely disposed on the pivoting cover 33 and the rear cover body 322.

The mounting method of the mount 1 will be described with reference to fig. 15A to 17B. As shown in fig. 15A, the slider legs 242 of the two stop sliders 24 are respectively projected downward through the two sliding through grooves 218 of the fixing bracket 21 while the slider blocks 241 are placed on the two sliding through grooves 218. The outer end portions of the two slider return springs 25 abut against spring seats (which may be, for example, dovetail grooves 213 of the support plate 211) on the support plate 211, respectively, and the inner end portions abut against outer end portions of the slider blocks 241, respectively, so that the two stop sliders 24 are biased toward each other within the sliding through groove 218.

As shown in fig. 15B, while the manual opening stop sliders 24 are moved away from each other, the guide bent portions 222 and the dovetails 223 of the sliding bracket 22 are aligned with the left and right ends of the support plate 211 of the fixed bracket 21 and the dovetail grooves 213, respectively, to slide the sliding bracket 22 onto the support plate 211 of the fixed bracket 21. Thereafter, the stop slider 24 is released, and the tapered inner end portions of the two stop sliders 24 are received in the receiving openings of the two stop seats 228 of the sliding bracket 22, respectively.

As shown in fig. 15C, the attachment bracket 26 is fixed to the attachment plate 212 of the fixing bracket 21 to which the slide bracket 22 is assembled by a fastener such as a screw, and as shown in fig. 15D, the attachment bracket 26 is directly fixed to the frame 91 of the seat back 9 by a fastener such as a screw.

As shown in fig. 16A, the button return spring 346 of the stop release button 34 is placed on the base plate 341 (for example, on a fixed protrusion of the base plate 341). As shown in fig. 16B, the coupling post 342 and the unlocking piece 343 of the stopper release button 34 are aligned with the through hole 314 and the opening 315 of the case 313 of the fixed cover 31, respectively, and the stopper release button 34 is inserted into the case 313 from below to above until the protrusion 345 of the coupling post 342 passes through the through hole 314.

As shown in fig. 16C, the fixing cover 31 is fixed to the back plate 92 of the seat back 9 by welding or the like, and the back plate 92 is connected to the frame 91 of the seat back 9 by snap-fitting or the like, with the slide bracket 22 and the fixing bracket 21 being located inside the fixing cover 31.

Referring to fig. 16D, the pivoting cover 33 is inserted into the rear cover body 322 of the sliding cover 32 until the two protrusions 324 on the rear cover body 322 enter the corresponding grooves 334 of the pivoting cover 33.

Referring to fig. 16E, the fixing concave portion 329 of the front side cover 321 of the slide cover 32 is aligned with and receives the fixing convex portion 229 of the slide bracket 22, thereby connecting the slide cover 32 assembled with the pivot cover 33 to the slide bracket 22.

Referring to fig. 17A and 17B, a display screen fixing piece 231 and a slide bracket fixing piece 232 of the pivot bracket 23 are fixed to the display screen 8 and the fixing hole 226 of the slide bracket 22 by fasteners such as screws, respectively, to pivotally support the display screen 23 on the slide bracket 22. Thereby completing the installation of the mounting bracket 1.

The method of operation of the mounting bracket 1 will now be described with reference to figures 18A to 22B. Fig. 18A and 18B show a side view and a side sectional view, respectively, of the mounting 1 in an initial position. In the initial position, the telescopic pivot assembly 2 and the cover assembly 3 of the mounting 1 are both in a retracted state and the display screen 8 is in a vertical position. The sliding bracket 22 of the telescopic pivot assembly 2 is in its initial position (i.e. longitudinally forwardmost position) relative to the support bracket 21 and is in a rest condition (i.e. the stop slider 24 engages the stop seat 228 of the sliding bracket 22). The sliding cover 32 is in its longitudinally forwardmost position relative to the fixed cover 31.

The occupant releases the stop of the slide bracket 22 on the support bracket 21 by pressing the stop release button 34 of the cover assembly 3 upward. At the same time, the occupant pulls the display screen 8 longitudinally rearward, thereby causing the sliding bracket 22 to slide rearward relative to the support bracket 21 from its initial position until the maximum extended position is reached (as shown in fig. 19A and 19B). Since the sliding cover 32 is fixed to the sliding bracket 22, the sliding movement of the sliding bracket 22 causes the sliding cover 32 to move rearward relative to the fixed cover 31 until the maximum protruding position is reached. After pulling the display screen 8 to the proper longitudinally extended position, the occupant releases the stop release button 34. The stop release button 34 is moved downward to the non-depressed position by the bias of the button return spring 346, thereby re-stopping the slide bracket 22 on the support bracket 21.

In contrast to the back-pulling action described above, the occupant can push the display screen 8 back to the initial position from any longitudinally extended position by pressing the stop release button 34 of the canopy assembly 3 upward and pushing the display screen 8 longitudinally forward.

Fig. 20A and 20B show a side view and a side sectional view, respectively, of the mounting 1 in any longitudinal position, when the display screen 8 is in a vertical position. As shown in fig. 21A and 21B, the occupant can pivot the upper portion of the display screen 8 rearward or pivot the lower portion of the display screen 8 forward. The display screen 8 is pivoted rearward from the upright position by the pivot bracket 23 until a rearward maximum pivot position is reached at which the back of the display screen 8 abuts against the rearward pivot stop piece 227R of the slide bracket 22. The rearward pivoting of the display screen 8 causes the pivoting cover 33 to pivot rearwardly relative to the sliding cover 32 so that the pivoting cover 33 always shields the connection between the display screen 8 and the telescopic pivot assembly 2.

As shown in fig. 22A and 22B, the occupant may push the upper portion of the display screen 8 forward or pull the lower portion of the display screen 8 backward. The display screen 8 is pivoted forward from the upright position by the pivot bracket 23 until a forward maximum pivot position is reached at which time the back of the display screen 8 abuts against the forward pivot stop 227F of the slide bracket 22. The forward pivoting of the display screen 8 causes the pivoting cover 33 to pivot forward relative to the sliding cover 32 so that the pivoting cover 33 always shields the connection between the display screen 8 and the telescopic pivot assembly 2.

A mounting bracket 1001 according to a second embodiment of the present disclosure will be described below with reference to fig. 23A and 23B. The mount 1001 will have the same or similar structure indicated by the reference numeral increased by 1000 in the mount 1. As shown, the mounting bracket 1001 includes a telescoping pivot assembly 1002 and a cover assembly (not shown). Telescoping pivot assembly 1002 provides for telescoping movement of display screen 1008 in a longitudinal direction and/or pivoting movement about a transverse pivot axis. The cover assembly conceals telescoping pivot assembly 1002 in any position of display screen 1008 (including any longitudinal position between the initial position and the maximum extended position, and any rotational position between the forward maximum pivot position and the rearward maximum pivot position) to protect telescoping pivot assembly 1002, protect occupants, and enhance the overall aesthetics of the mount.

The telescopic pivot assembly 1002 includes a slidably connected support bracket 1021 and a sliding bracket 1022. The support bracket 1021 serves to support the sliding bracket 1022 and guide the sliding bracket 1022 to slide thereon. The sliding support 1022 is used to drive the display screen 1008 to move longitudinally and reciprocally relative to the supporting support 1022. The telescoping pivot assembly 1002 also includes a pivot bracket 1023. The pivot bracket 1023 is used to pivot the display screen 1008 back and forth about a transverse pivot axis relative to the sliding bracket 1022.

The support bracket 1021 and the sliding bracket 1022 have substantially the same structure as the support bracket 21 and the sliding bracket 22 except that the support bracket 1021 and the sliding bracket 1022 do not include a stopping member. That is, the support bracket 1021 does not include the slide through slot 218, the stop slider 24, and the slider return spring 25 in the support bracket 21, and the slide bracket 1022 does not include the stop seat 228 in the slide bracket 22. In contrast, the sliding support 1022 is controllably slid relative to the support 1021 by the driving of the motor 1071. In some embodiments, the motor 1071 is fixed to the upper surface of the sliding bracket 1022. The lead screw 1072 is disposed above the upper surface of the sliding bracket 1022 in the longitudinal direction, and is fixed at the rear end thereof to the support bracket 1021 or the connecting bracket 1026. The motor 1071 rotates the nut to travel on the lead screw 1072, so that the sliding support 1022 can slide on the support 1021.

The pivot bracket 1023 has substantially the same structure as the pivot bracket 23. A motor 1073 is provided at the back of the display screen 1008, and an output shaft of the motor 1073 is connected to the pivot bracket 1023 to drive the display screen 8 to controllably pivot back and forth relative to the slide bracket 1022.

As described above, the support bracket 1021 and the sliding bracket 1022 do not include the stop assembly. In correspondence with this, the fixing cover 1031 does not include the box body 313 and the stop release button 34 in the fixing cover 31. Except for this, the structures of the fixed cover, the sliding cover, and the pivoting cover of the cover assembly are substantially the same as those of the fixed cover 31, the sliding cover 32, and the pivoting cover 33 of the cover 3, and will not be described in detail.

In operation, the rider controls the motor 1071 through the controller to effect longitudinal reciprocation of the display 1008. The rider controls the motor 1073 through the controller to effect pivotal movement of the display screen 1008.

In some embodiments, the mounting bracket 1001 may be provided with only the motor 1071 for driving the longitudinal movement and not the motor 1073 for driving the pivotal movement. Thus, the mounting bracket 1001, like the mounting bracket 1, allows the display 1008 to be pivoted manually by the rider. In some embodiments, the mounting bracket 1001 may be provided with only the motor 1073 for driving the pivoting motion, and not the motor 1071 for driving the longitudinal movement. Therefore, the mount 1001, like the mount 1, achieves the longitudinal movement of the display 1008 by the occupant pressing the end stop release button upward and pushing or pulling the display 1008.

According to the mounting bracket of the embodiment of the disclosure, the installation structure scheme of rotation and extension of the display screen of the vehicle seat is realized, the development requirements of customers in a host factory can be well met, and the use comfort of the seat is greatly improved.

The installation frame according to the embodiment of the disclosure can shield the internal structure of the display screen in any position, so that the internal structure is not only protected from being damaged by external invaders, but also the passengers are prevented from being pinched by the internal structure. In addition, the mounting bracket according to the embodiment of the disclosure also improves the aesthetic degree.
