Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a multi-dimensionally adjustable rear table top for an automobile. Background Art

[0002] The small table on the back of a car seat is a very practical in-car accessory. It is installed behind the front seats of the car. It can not only provide passengers with additional work or dining space, but also be used to place food, mobile phones, laptops and other items. The basic function of the small table is that when not in use, the small table is folded to a state parallel to the back of the car seat through the connecting rod assembly. When in use, the small table is unfolded to a horizontal state facing the rear passengers through the connecting rod assembly. These small tables can usually be pre-installed before leaving the factory or installed later on the back of the front table and chair of the car.

[0003] The backrest angle of the front seat of the car can be adjusted to make the front row riding experience more comfortable. For this reason, the angle of the small table in the back row will also change when it is unfolded, so that it cannot maintain the original horizontal state. Chinese patent CN1186883425A discloses an angle-adjustable small table for car seats, and discloses technical features. A control dial is provided on the small table. By rotating the control dial, the angle control block is driven through the control connecting rod and the angle control slider, so that the angle control block is connected to the upper connecting rod bracket or the lower connecting rod bracket, thereby adjusting the angle of the small table. This solution can only adjust the angle of the small table, and the structure is complicated, and it cannot meet the adjustment needs of other dimensions of the small table.

[0004] After the small table is unfolded, the distance between the small table and the rear passengers is usually fixed and preset to a comfortable distance. However, the small table installed later usually cannot adapt well to the differences in rear space of different cars and cannot achieve the preset comfortable distance. However, when the small table needs to be adjusted in angle, the control dial, control link, angle control slider and angle control block are all configured inside the small table, which cannot adapt to position adjustment in other dimensions.

DETAILED DESCRIPTION

[0033] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] like Figures 1 to 11 As shown in FIG. 1 , a multi-dimensionally adjustable rear table for a car according to an embodiment of the present invention is shown. Figure 1, the small table on the back of the car seat includes a mounting module, a connecting rod assembly 20 and a table body 30. Among them, the mounting module is used to be fixed to the back of the car seat and provide a fixed installation space for the table body 30. In this embodiment, the mounting module is configured as a back panel body 10, and in other embodiments, it can also be a simple mounting bracket. The back panel body 10 can be configured in the shape of a car seat back panel, making the car seat more beautiful, and at the same time, the table body 30 can be stored in conjunction with the connecting rod assembly 20. The table body 30 is used to provide the user with the function of placing items, and it is connected to the back panel body 10 through the connecting rod assembly 20. In order to make the table body 30 more firm and stable, the connecting rod assembly 20 is usually configured with two groups, and each group of the connecting rod assembly 20 is respectively configured with two connecting rods, namely an upper connecting rod 21 and a lower connecting rod 22. The table body 30 includes a panel 33 and a bottom plate 34, and a table connecting rod base 32 is provided on each side of the bottom plate 34 of the table body 30. The two groups of connecting rod assemblies 20 are hingedly connected corresponding to the table board connecting rod bases 32 on both sides. The upper connecting rod 21 and the lower connecting rod 22 cooperate with each other. When the upper connecting rod 21 and the lower connecting rod 22 swing to the lower limit position, the table board body 30 is displaced and stored in the receiving groove. When the upper connecting rod 21 and the lower connecting rod 22 swing to the upper limit position, the upper connecting rod 21 and the lower connecting rod 22 abut against each other, and at the same time, the table board body 30 is displaced and unfolded outside the receiving groove, and maintains a horizontal state facing the passengers.

[0035] To achieve multi-dimensional adjustment, in detail, the upper connecting rods 21 of the connecting rod assemblies 20 on both sides are respectively provided with adjustment sliders 70. The table top connecting rod bases 32 at the positions corresponding to the connecting rod assemblies 20 on both sides are respectively provided with positioning blocks 31. The adjustment slider 70 is configured with a sliding operation portion 71 exposed on the upper connecting rod 21, and the adjustment slider 70 is provided with a wedge portion 72 on the side facing the table top connecting rod base 32. The wedge portion 72 cooperates with the positioning block 31 so that the wedge portion 72 will abut against the positioning block 31 at different positions as the sliding operation portion 71 moves, and the distance between the upper connecting rod 21 and the positioning block 31 is changed accordingly.

[0036] refer to Figures 9 to 11Therefore, when adjusting the small table on the back of the car seat, the user holds the table body 30 with both hands, puts his fingers on the exposed sliding operation part 71, and slides the sliding operation part 71 forward or backward. The wedge-shaped part 72 will change position along with the sliding operation part 71, and the positions of the wedge-shaped part 72 with different thicknesses will abut against the positioning block 31. When the wedge-shaped part 72 moves backward, the thicker position will abut against the positioning block 31. When the wedge-shaped part 72 moves forward, the thinner position will abut against the positioning block 31. The thicker the position abutting against the positioning block 31, the farther the distance between the upper connecting rod 21 and the positioning block 31, and the larger the minimum angle between the upper connecting rod 21 and the table connecting rod base 32, the table body 30 will be adjusted upward relative to the abutment. Similarly, the thinner the position abutting against the positioning block 31, the closer the distance between the upper connecting rod 21 and the positioning block 31, and the smaller the minimum angle between the upper connecting rod 21 and the table board connecting rod base 32, the table board body 30 is adjusted downward relative to the abutment. When in use, the larger the angle of the front seat backrest of the car, the unadjusted front table board body 30 will tilt downward, so it is necessary to move the sliding operation part 71 backward, so that the thicker wedge-shaped part 72 abuts against the positioning block 31, and the table board body 30 is tilted upward, so as to keep the table board body 30 in a horizontal position.

[0037] At the same time, in order to achieve multi-dimensional adjustment, refer to Figure 3 and Figure 3 , the bottom of each table board link base 32 is fixedly connected with a sliding part 40, and the two sides of the bottom plate 34 of the table board body 30 are fixedly connected with guide rails 50, and the table board link base 32 is displaceably installed in the guide rails 50 through the sliding part 40. When the upper link 21 and the lower link 22 swing to the upper limit position, the table board body 30 is unfolded into a horizontal state. The upper link 21, the lower link 22 and the table board link base 32 can maintain the posture when unfolded horizontally, and the table board body 30 and the guide rail 50 can be operated by the user to move towards or away from the front seat, respectively, so as to achieve a corresponding reduction or increase in the distance between the table board body 30 and the rear passengers.

[0038] Therefore, in the present invention, the table top connecting rod base 32 and the table top body 30 can slide relative to each other, so that the unfolded table top can freely extend and retract at different distances to adjust the distance between it and the car table and chair, so that the rear passengers can adjust the appropriate table top distance, and the rear passengers can use the table top comfortably in the rear spaces of cars of different sizes.

[0039] In summary, in this embodiment, the angle adjustment slider 70 is set on the upper connecting rod 21, and the matching positioning block 31 is set on the table board connecting rod base 32, so as to adjust the minimum angle between the table board connecting rod base 32 and the upper connecting rod 21, and realize the angle adjustment of the table board body 30 in the unfolded state. At the same time, a sliding part 40 is set below the table board connecting rod base 32, and a guide rail 50 is set on the table board body 30. Through the cooperation of the sliding part 40 and the guide rail 50, the table board body 30 can be telescopically changed relative to the table board connecting rod base 32 without changing the angle between the table board body 30 and the table board connecting rod base 32. Telescopic adjustment and angle adjustment do not affect each other, and are highly integrated in components such as the connecting rod and the table board connecting rod base 32.

[0040] refer to Figure 4 and Figure 5 In order to make the table top connecting rod base 32 and the table top body 30 move smoothly, in this embodiment, specifically, the sliding part 40 includes a ball 42, a sliding base 41, a brake block 43 and an elastic member 44. The sliding base 41 is provided with a retaining hole, and the ball 42 is rollably disposed in the retaining hole. The ball 42 and the guide rail 50 are abutted and matched to make the sliding part 40 and the guide rail 50 relatively displaced. The brake block 43 is slidably disposed on the sliding base 41 in a vertical direction relative to the guide rail 50, and the two ends of the elastic member 44 are respectively disposed between the brake block 43 and the sliding part 40, so as to push the brake block 43 to abut against the inner wall of the guide rail 50.

[0041] It is worth noting that, in the absence of external force, the brake block 43 will abut against the right inner wall of the guide rail 50 under the elastic force of the elastic member 44, and at the same time, the elastic member 44 will also push the sliding base 41 to abut against the left inner wall of the guide rail 50. The overall width of the sliding base 41 is increased, so that the brake block 43 and the sliding base 41 abut against the guide rail 50 at the same time, and a large friction force is generated between the sliding part 40 and the guide rail 50, so that the rolling displacement of the ball 42 fails.

[0042] When a rightward thrust is applied to the table top body 30, the brake block 43 is displaced toward the inside of the sliding base 41, and the overall width of the sliding base 41 is reduced, so that a gap is maintained between the sliding base 41 and the guide rail 50, so that the friction between the sliding part 40 and the guide rail 50 is less, and the sliding part 40 rolls and displaces on the guide rail 50 through the ball bearing 42.

[0043] It can be seen that the present invention provides a brake block 43 on the sliding portion 40 of the ball bearing 42, so that the table board body 30 can maintain its own telescopic position without the action of a rightward external force, and is not easy to move, so as to achieve telescopic adjustment of any distance within a range. At the same time, when the table board body 30 is subjected to a rightward external force, it can roll and slide, and the position can be adjusted quickly and labor-savingly.

[0044] refer to Figure 4 and Figure 5 Specifically, in this embodiment, the guide rail 50 is provided with a base groove 51 that matches the displacement of the sliding base 41, so that the displacement process is free of obstruction or contact. The sliding base 41 is provided with wedge-shaped protrusions on both sides, and the base groove 51 is provided with wedge-shaped grooves 53 on both sides. The wedge-shaped protrusions of the sliding base 41 are clearance-matched with the wedge-shaped grooves 53, and the end of the brake block 43 is configured as a wedge shape that matches with the wedge-shaped grooves 53. In the absence of external force, the wedge-shaped protrusions and the wedge-shaped grooves 53 will abut against each other under the action of the brake block 43, and a large friction force will be generated. Under the action of external force, the wedge-shaped protrusions on both sides and the wedge-shaped grooves 53 on both sides can maintain a gap distance, and only the brake block 43 contacts the guide rail 50, so that the friction force is greatly reduced, and the ball 42 is used to slide. .

[0045] refer to Figure 4 and Figure 5 Specifically, in this embodiment, the wedge-shaped protrusion of the sliding base 41 is provided with a retaining hole, and the ball 42 is rollably disposed in the retaining hole. The upper and lower sides of the wedge-shaped groove 53 are provided with ball grooves 52, and the ball 42 abuts against the ball grooves 52. The ball 42 is disposed on the wedge-shaped protrusion, extending outside the retaining hole and contacting the ball groove 52. The retaining hole retains the ball 42 in the front-to-back direction, and a certain gap can be set with the ball 42 in the left-to-right direction, so that the sliding base 41 can be displaced in the left-to-right direction to realize the automatic braking function. The ball grooves 52 on the upper and lower sides allow the ball 42 to withstand downward pressure or upward thrust, thereby ensuring that the table board body 30 only displaces along the guide rail 50.

[0046] refer to Figure 4 and Figure 5 Specifically, in this embodiment, four balls 42 are provided, and two balls 42 are respectively distributed in the front and rear of the sliding base 41 along the guide rail 50. The brake block 43 is provided at the bottom of the sliding base 41, and is alternately provided between the balls 42 on the front and rear sides. The balls 42 are provided in front and rear of the brake block 43, which facilitates the stability of the displacement of the sliding part 40 after the brake is released. Each table top connecting rod base 32 is respectively provided with two sliding parts 40, so that the table top body 30 can remain stable when subjected to downward pressure or upward push force.

[0047] refer to Figures 5 to 7Specifically, in this embodiment, the table board body 30 is further provided with a locking block 60 and a limiting vertical plate 62. The limiting vertical plate 62 is provided on the table board body 30 in parallel with the guide rail 50 and located on one side of the guide rail 50. The locking block 60 is fixedly connected to the table board connecting rod base 32 and is located above the limiting vertical plate 62. A locking buckle 61 is elastically and integrally provided on one side of the locking block 60 facing the limiting vertical plate 62. The limiting vertical plate 62 is provided with a limiting groove for limiting the displacement of the locking buckle 61, and a sliding groove for allowing the locking buckle 61 to slide. The sliding groove of the limiting vertical plate 62 is provided in the middle, and at least two limiting grooves are provided on the side of the limiting vertical plate 62 away from the back plate body 10, and one limiting groove is provided on the side of the limiting vertical plate 62 close to the back plate body 10.

[0048] It is worth noting that, in the initial state, the locking block 60 is displaced to the upper part of the first limiting groove away from the side of the back panel body 10, and the locking buckle 61 is fixed in the limiting groove. When the distance of the table board body 30 needs to be reduced, the table board body 30 is pushed so that the locking block 60 is displaced to the upper part of the second limiting groove away from the side of the back panel body 10, and the locking buckle 61 is fixed in the limiting groove, so that the table board body 30 is close to the front car seat. When the distance of the table board body 30 needs to be increased, the table board body 30 is pushed so that the locking block 60 is displaced to the upper part of the slide groove, and the locking buckle 61 cannot be fixed to the slide groove. Under the action of the brake block 43, if there is no external force to the right, the table board body 30 can maintain any position of the slide groove. If there is an external force to the right, the table board body 30 can change its position on the slide groove in a rolling manner. When the table board body 30 needs to be adjusted to the distance of the nearest passenger, the table board body 30 is pulled to the upper part of the limiting groove close to the side of the back panel body 10, and the locking buckle 61 is fixed in the limiting groove.

[0049] It can be seen that in the present invention, it is necessary to simultaneously apply a force perpendicular to the telescopic direction and a force parallel to the telescopic direction. The telescopic adjustment operation is ingenious, and safe and stable telescopic adjustment of the small table can be achieved.

[0050] refer to Figures 5 to 7 At least two limiting plates 62 are provided, and the limiting plates 62 are parallel to each other. The width of the locking buckle 61 matches the overall width of each limiting plate 62, so that the comprehensive strength of the locking block 60 and the limiting plate 62 is improved.

[0051] refer to Figures 5 to 7 The table top body 30 includes a bottom plate 34 and a panel 33, the guide rail 50 and the limiting vertical plate 62 are fixedly arranged on the bottom plate 34, the bottom plate 34 and the panel 33 are surrounded to form an inner cavity, the table top connecting rod base 32 and the sliding part 40 are located in the inner cavity, so as to be more beautiful.

[0052] refer to Figure 3Specifically, in this embodiment, the wedge-shaped portion 72 of the adjusting slider 70 is provided with a plurality of tooth grooves on the side facing the table board body 30. Each tooth groove is distributed along the slope of the bottom of the wedge-shaped portion 72. The top end of the positioning block 31 is configured as a tip, and the tip of the positioning block 31 fits into the tooth groove of the adjusting slider 70. Therefore, when the adjusting slider 70 is moved, the tip of the positioning block 31 will fit into the tooth grooves of different slope heights, and the distance between the upper connecting rod 21 and the positioning block 31 will change accordingly.

[0053] refer to Figure 3 Specifically, in this embodiment, the interior of the wedge-shaped portion 72 is provided with a groove body open toward one side of the table board body 30, and a wedge block 73 made of elastic material is provided in the groove body. The wedge block 73 is also provided with teeth. When in use, the bottom of the wedge block 73 will protrude from the bottom of the wedge-shaped portion 72, and preferentially abut against the tip of the positioning block 31, releasing the elastic force during the contact process, thereby achieving a silent effect.

[0054] refer to Figure 3 Specifically, in this embodiment, the upper connecting rod 21 is provided with an inner cavity, the inner cavity is provided with a strip-shaped opening, and the adjusting slider 70 is provided with a neck 74 connecting the sliding operation part 71 and the wedge-shaped part 72, and the neck 74 can be linearly slidably arranged in the strip-shaped opening.
