Description

Technical Field

[0001] This utility model relates to the field of automotive supplies technology, and in particular to a table structure for a car center armrest. Background Technology

[0002] With the increasing prevalence of automobiles in daily life, people's demands for the convenience and functionality of car interior facilities are rising. Car tray tables, as auxiliary devices that provide passengers with space for placing items, working, and dining, are gradually gaining consumer attention. However, current car tray table structures generally have limitations in use; most can only be fixed to the front or rear seats and cannot be freely rotated or moved to the most convenient position according to the passenger's actual needs. This, to some extent, limits the user experience and practicality of car tray tables.

[0003] For example, Chinese patent application number 202021117511.9 discloses a front center armrest and a car with a rear seat tray table. This tray table is mounted behind the front seats via a fixed bracket, allowing only rear passengers to use it. Its position is fixed and cannot be adjusted to suit the needs of front passengers. When rear passengers do not need the tray table, but front passengers need it for placing items or working, the tray table becomes useless, resulting in a waste of resources. Similarly, Chinese patent application number 202220665914.X discloses a mechanism for a shared tray table between the front and rear seats in the center console and a car. By combining the armrest box and the center console tray table, it achieves the function of a shared tray table for both front and rear passengers, improving the utilization rate of the tray table to some extent. However, this tray table is still fixed to the armrest box. Although it can be adjusted to some extent along the length of the car body by sliding the armrest box, its overall position remains relatively fixed and cannot be freely moved to the most convenient position for passengers, leaving considerable room for improvement in terms of flexibility.

[0004] To address the aforementioned issues, there is an urgent need for a novel tray table structure for automotive center armrests. This structure breaks through the limitations of traditional tray tables, which can only be fixed in the front or rear seats. It allows the tray table to move freely between the front and rear seats and can be freely rotated and adjusted to the most convenient position according to passenger needs. Regardless of whether passengers are sitting in the front or rear seats, or in any seating position or interior space layout, they can easily use the tray table, greatly improving its convenience and practicality, and providing passengers with a more comfortable and efficient travel experience.

Furthermore, a limiting component 1120 is provided on the fixing plate 1100. The limiting component 1120 includes a limiting through hole 1121 provided on the fixing plate 1100 and a limiting fastener 1122 passing through the limiting through hole 1121.

[0061] like Figure 1 and Figure 2 As shown, in this embodiment, the adjustment part 2200 extends downward to form an adjustment guide rod 2201 corresponding to the support guide rod 1130. An adjustment groove 2202 is provided on the adjustment guide rod 2201, and a positioning member 1131 and a fastener 1132 passing through the adjustment groove 2202 are provided on the support guide rod 1130.

[0062] In this embodiment, the mounting base 1000 has a U-shaped cross-section and consists of two symmetrically distributed fixing plates 1100 and an adjusting plate 1200 that slidably connects the two fixing plates 1100. Two adjusting bolts 1210 connecting the fixing plates 1100 are respectively provided at both ends of the adjusting plate 1200, and a limiting groove 1110 for slidably connecting the adjusting bolts 1210 is provided on the fixing plate 1100. Simultaneously, limiting components 1120 are symmetrically provided on both sides of the mounting base 1000. Each limiting component 1120 includes a limiting through hole 1121 provided on the fixing plate 1100 and a limiting fastener 1122 passing through the limiting through hole 1121.

[0063] The main function of the mounting base 1000 is to provide a stable mounting foundation for the entire table structure and fix it to the center armrest of the car. The distance between the two fixing plates 1100 can be controlled by adjusting the plate 1200, adjusting the bolt 1210, and the limiting slide 1110 to adapt to different car models and interior space layouts, improving the versatility and adaptability of the table structure. The limiting component 1120 is used to further secure the mounting base 1000, preventing it from shaking or shifting during vehicle operation.

[0064] Specifically, the "U"-shaped cross-section design allows the mounting base 1000 to better fit the bottom of the car's center armrest, improving installation stability. The structure of the adjusting plate 1200 and the limiting slide 1110 allows for flexible adjustment of the distance between the two fixing plates 1100 to meet the installation requirements of different car models. The addition of the limiting component 1120 enhances the fixing effect of the mounting base 1000, ensuring the safety of the table structure during use.

[0065] In this embodiment, the fixing plate 1100 is a long strip-shaped plate structure made of aluminum alloy, which has high strength and light weight. Its cross-section is L-shaped, with one end contacting the center armrest of the car and the other end connecting to the adjusting plate 1200. One or more limiting through holes 1121 are provided on the fixing plate 1100 for installing limiting fasteners 1122. The adjusting plate 1200 is a rectangular plate structure, also made of aluminum alloy. Connecting portions connecting to the two fixing plates 1100 are provided at both ends of the adjusting plate 1200, and connecting holes corresponding to the limiting through holes 1121 on the fixing plates 1100 are provided on the connecting portions. Two adjusting bolts 1210 are also provided at both ends of the adjusting plate 1200. The adjusting bolts 1210 pass through the limiting grooves 1110 on the fixing plate 1100. By adjusting the position of the adjusting bolts 1210 in the limiting grooves 1110, the distance between the two fixing plates 1100 can be controlled.

[0066] Specifically, the adjusting bolt 1210 can be a hex socket head cap screw with a hex head for easy tightening and loosening with a hex wrench. Hex socket head cap screws offer high tightening force and good anti-loosening performance, making them suitable for applications requiring frequent adjustment. A thread is provided in the limiting through-hole 1121, and the limiting fastener 1122 uses a large-diameter nut for adjusting the tightness of the car's center armrest via a threaded connection; alternatively, a large-diameter bolt can be used directly, eliminating the need for threads in the limiting through-hole 1121.

[0067] In other embodiments, the limiting fastener can be a limiting pin, which is a cylindrical structure with a chamfer at one end for easy insertion into the limiting through hole on the fixing plate. The limiting pin is made of stainless steel, which has high strength and corrosion resistance, and can effectively fix the position of the mounting base. Alternatively, a stop block can be used. The stop block is a rectangular block structure made of rubber. The stop block is adhered to the fixing plate with adhesive and contacts the center armrest of the car.

The coordination of the second guide slider 3320, guide protrusion 3120, and guide groove 3130 provides guidance for the movement of the table body 3200, making it more stable during movement and reducing operational difficulty. The bottom cover housing 3210 protects components such as the adjusting rod 3100 and guide protrusion 3120, and also serves an aesthetic purpose.

[0073] In this embodiment, the flexible adjustment function of the sliding table assembly 3000 allows passengers to adjust the position and angle of the table body 3200 according to their needs, improving comfort and convenience. The guide protrusion 3120 and guide groove 3130 make the movement of the table body 3200 smoother, reducing shaking and jamming, and improving the smoothness of operation. The design of the bottom cover shell 3210 not only protects the internal components but also enhances the overall aesthetics of the table structure.

[0074] Specifically, the adjusting slide rod 3100 has a cylindrical structure and is made of stainless steel, which has high strength and corrosion resistance. A sliding guide groove 3110 is formed on the adjusting slide rod 3100. The sliding guide groove 3110 has a rectangular groove structure and extends along the axial direction of the adjusting slide rod 3100. A guide protrusion 3120 is provided at the lower end of the adjusting slide rod 3100 along the sliding direction of the second guide slider 3320. The guide protrusion 3120 has a cuboid structure and is integrally formed with the adjusting slide rod 3100. The guide protrusion 3120 forms a guide groove 3130 that allows the second guide slider 3320 to slide. The guide groove 3130 has a rectangular groove structure and communicates with the sliding guide groove 3110.

[0075] The table body 3200 has a plate-like structure and is made of high-strength engineering plastic. A bottom cover housing 3210, which is box-shaped and fixedly connected to the table body 3200, is provided at the lower end of the table body 3200. A movable opening 3220 is provided in the bottom cover housing 3210 to allow the passage of an adjusting slide rod 3100 and a guide protrusion 3120. The shape and size of the movable opening 3220 match the cross-sectional shape of the adjusting slide rod 3100 and the guide protrusion 3120. In some embodiments, the table body can be configured as a foldable tabletop structure.

[0076] The second locking device 3300 includes a second locking member 3310 that passes through the table body 3200 and the sliding guide groove 3110. The second locking member 3310 is a hand-tightening screw. The head of the hand-tightening screw has a round structure and the surface is provided with anti-slip texture, making it easy to tighten and loosen by hand. A second guide slider 3320 is threadedly connected to the end of the second locking member 3310 away from the table body 3200. The second guide slider 3320 has a rectangular block structure and is made of stainless steel or high-strength plastic. By tightening the hand-tightening screw, the table body 3200 can be fixed on the adjusting slide rod 3100; by loosening the hand-tightening screw, the table body 3200 can slide on the adjusting slide rod 3100.

[0077] In some embodiments, the second locking element may be a quick-release clamp in addition to a hand-tightening screw. The quick-release clamp is a mechanical clamping device that allows for rapid clamping and releasing via manual operation. It offers advantages such as high clamping force and ease of operation, making it suitable for applications requiring frequent adjustments to the table's position.

[0078] In some embodiments, the second guide slider may employ an eccentric wheel locking device, which includes an eccentric wheel and a locking handle. By rotating the locking handle, the eccentric wheel can be rotated, thereby locking and unlocking the table body. The eccentric wheel locking device has advantages such as reliable locking and convenient operation, and can effectively ensure the stability of the table body.

[0079] When adjusting the position of the table structure used in the center armrest of a car:

[0080] Initial unlocking: The first locking device includes a steering groove disposed on the central plate, a first guide slider slidably connected to the steering groove, and a first locking member passing through the first guide slider and the sliding groove. The second locking device includes a second locking member passing through the table body and the sliding groove, with a second guide slider threadedly connected to the end of the second locking member away from the table body.

[0081] Loosen the first and second locking parts so that the first guide slider can slide in the steering groove and the second guide slider can slide in the guide groove formed by the guide protrusion of the adjusting rod. The table body and the adjusting rod can slide relative to each other.

[0082] Movement and Steering: Pushing the table allows it to move relative to the adjustment platform via a sliding guide, a second locking device, and a first locking device. Due to the presence of a steering track, the table can be steered during movement. For example, when changing from facing the front row passengers to facing the rear row passengers, the table can move and steer along the trajectory of the steering track.

[0083] The guide protrusions and guide grooves on the adjusting slide rod provide guidance for the sliding of the second guide slider, making the table more stable during movement and reducing the difficulty of operation. A sliding opening is provided in the bottom cover of the table to allow the adjusting slide rod and guide protrusion to pass through, ensuring smooth movement of the table.

[0084] Relocking: After the table is moved to the appropriate position (facing the front or rear passengers) and angle, tighten the first and second locking pieces to lock the table to the adjustment platform and the adjustment slide to the table, thus fixing the table in the required position for passenger use.

[0085] In another embodiment, it is basically the same as the above embodiment, except that:

[0086] The first locking device includes a first locking member and a first guide slider that is threadedly connected to the first locking member. The first guide slider is fixedly connected to the central plate and does not have a steering groove. Furthermore, a "T"-shaped sliding guide groove is provided on the adjusting slide rod.

[0087] When the table needs to be moved between the front and rear seats, the position of the table can be adjusted by the first locking element located on the central plate and the "T"-shaped sliding guide groove.

[0088] This utility model has many application scenarios, including but not limited to the following described scenarios:

[0089] During family road trips, rear passengers can move the tray table to a suitable position to place food, drinks, books, tablets, and other items, making it convenient to eat, read, and entertain themselves during the journey, thus improving the comfort and enjoyment of the trip.

[0090] For business people, using a tray table in the back seat of a car makes it convenient to work, such as viewing documents or using a laptop, making full use of travel time to handle work matters and improving work efficiency.

[0091] In long-distance passenger vehicles, passengers can install a tray table structure in the center armrest to place personal items, alleviate fatigue from long journeys, and enhance the travel experience.

[0092] For passengers with special needs, such as those with mobility impairments, the tray table structure can provide convenience by allowing them to place items or perform simple operations, thus improving the convenience and comfort of their travel.
