Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a car seat tray with telescopic function. Background Technology

[0002] With the continuous development of the automotive industry, car seat tray tables, as an important feature to enhance the passenger experience, are receiving increasing attention for their design and function. Passengers often need to place items, eat, or work while traveling; therefore, car seat tray tables need sufficient length and stability to meet diverse usage scenarios. Currently, there are two common methods for adjusting the length of existing car seat tray tables on the market, but both have significant drawbacks. One common method is to use a folding structure to increase the tray table's length. While this folding tray table achieves length variation to some extent, it presents several problems. Visually, the folding mechanism is usually exposed, severely affecting the overall craftsmanship and aesthetics of the seat. More importantly, the unlocking mechanism is also exposed, making it easy for rear passengers, especially children, to accidentally activate it, causing the tray table to open unintentionally. This not only interferes with normal use but also poses a safety hazard, significantly impacting the passenger experience. Another method is to use a drawer-type telescopic structure to extend the tray table. However, this structure also has significant shortcomings. When extended, the drawer-type telescopic tabletop has a stepped surface. This unevenness causes items to easily slip when placed on it; it also affects the usability and comfort of using electronic devices such as laptops. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a car seat table with telescopic function, which can effectively adjust the length while ensuring aesthetic appearance, comfort and safety.

[0004] To achieve the above objectives, this utility model proposes a car seat tray with telescopic function, including a frame assembly, a middle section plastic part covering panel, a left side covering panel, and a right side covering panel. The frame assembly includes an upper tray frame assembly and a lower tray frame assembly that are slidably connected front to back. The front outer side of the lower tray frame assembly is covered by a first covering panel, and the rear outer side of the upper tray frame assembly is covered by a second covering panel. The top surfaces of the first and second covering panels are flush, and when their top surfaces are joined, they can form an outer covering panel that completely covers the frame assembly. The left side covering panel and the right side covering panel of the middle section plastic part are respectively contacted and connected to the left and right sides of the middle section plastic part covering panel, and are respectively fixedly connected to the upper tray frame assembly via push-to-close latches.

[0005] When the car seat tray table is in the extended state, the middle plastic part's middle covering panel, left side covering panel, and right side covering panel are all in contact with the top surfaces of the first and second covering panels, and the top surfaces of all three are flush with the top surface of the outer covering panel. When the car seat tray table is in the retracted state, the top surfaces of the first and second covering panels are in contact, and the middle plastic part's middle covering panel, left side covering panel, and right side covering panel can all sink down, thus being hidden inside the outer covering panel.

[0006] In the above scheme: the lower table frame assembly has two first arc-shaped holes arranged opposite each other on the left and right sides. The first arc-shaped holes extend counterclockwise from the front to the rear and upward. The upper table frame assembly has two second arc-shaped holes arranged opposite each other on the left and right sides. The second arc-shaped holes extend counterclockwise from the front to the rear and downward, and their ends extend horizontally to the rear to form a strip-shaped hole segment. The front end of the middle section plastic part covering the middle panel is rotatably connected to a first transverse rotating shaft. The first transverse rotating shaft rotates and slides between the two first arc-shaped holes. The rear end of the middle section plastic part covering the middle panel is rotatably connected to a second transverse rotating shaft. The second transverse rotating shaft rotates and slides between the two second arc-shaped holes.

[0007] When the car seat tray table is in the extended state, the first lateral pivot is located at the end of the two first arc-shaped holes, and the second lateral pivot is located at the front end of the two second arc-shaped holes, so that the middle covering panel, the left covering panel, and the right covering panel of the middle plastic part are all in contact with the top surfaces of the first and second covering panels; pressing the left and right covering panels of the middle plastic part allows them to be pushed-to-close. The upper table frame assembly is pushed forward under the action of the latch, which forces the first lateral pivot to slide forward along the first arc-shaped hole and simultaneously forces the second lateral pivot to slide backward along the second arc-shaped hole. This causes the middle covering panel of the middle section plastic part to sink automatically. When the first lateral pivot slides to the front end of the first arc-shaped hole, the upper table frame assembly is pushed forward again, which forces the second lateral pivot to slide along the strip-shaped hole section of the second arc-shaped hole. This achieves the top face contact between the first covering panel and the second covering panel, thereby hiding the middle covering panel, the left covering panel, and the right covering panel of the middle section plastic part inside the outer covering panel.

[0008] This structure, by setting a first and second arc-shaped hole with a specific orientation, and a first and second lateral pivot that cooperate with it, allows the middle section of the plastic part covering the panel to move smoothly along a predetermined trajectory during the extension and retraction of the small table. This design ensures the smoothness of the extension and retraction operation, reduces jamming and shaking, and improves the user experience.

[0009] In the above solution: the lower tabletop frame assembly has two longitudinally extending slots arranged opposite each other on the left and right sides. The two ends of the upper tabletop frame assembly are slidably connected to these slots via bolts and nuts, with two bolts at each end, spaced apart. This design allows the upper tabletop frame assembly to slide back and forth along the slots, thus enabling the tabletop to extend and retract, meeting the user's needs for tabletop length in different usage scenarios.

[0010] In the above scheme: a rotating shaft mounting bracket is welded on the lower table frame assembly. The rotating shaft mounting bracket has a U-shaped structure, and the two first arc-shaped holes are respectively arranged on both ends of the rotating shaft mounting bracket. This structure is relatively simple and easy to process and manufacture, making it convenient to arrange the first arc-shaped holes.

[0011] In the above solution: the lower table frame assembly includes two lower table side panels arranged opposite each other on the left and right. The front ends of the two lower table side panels are connected by a front-end reinforcing bracket, and the rear ends of the two lower table side panels are connected by a rear-end reinforcing bracket. The middle part of the front-end reinforcing bracket and the middle part of the rear-end reinforcing bracket are connected by a middle-section reinforcing bracket, forming a stable frame structure. This structure can provide users with a safer and more reliable user experience.

[0012] In the above scheme: the rotating shaft mounting bracket is welded to the middle front position of the middle section reinforcing bracket, and the two shaped holes are respectively arranged on the two lower table side plates. The structure is simple and the arrangement is convenient.

[0013] In the above scheme: the upper table frame assembly includes two upper table side panels arranged opposite each other on the left and right, the front ends of the two upper table side panels are connected by a middle reinforcing bracket, and two second arc-shaped holes are respectively arranged at the rear ends of the two upper table side panels. The structure is simple and the arrangement is convenient.

[0014] A bushing is provided between the upper table panel and the lower table panel on the same side, and the bushing is fitted onto the bolt.

[0015] In the above design: Lugs are provided on the inner walls of both upper table side panels. The left-side covering panel of the middle plastic component is fixed to the left lug via a push-to-close latch, and the right-side covering panel of the middle plastic component is fixed to the right lug via a push-to-close latch. Pressing the left and right covering panels of the middle plastic component, i.e., pressing the push-to-close latch, causes them to sink. Pressing the push-to-close latch again causes them to rise, thus making them flush with the outer covering panel when the car seat table is extended.

[0016] Push-to-close latch is an existing technology, an automatic spring-loaded locking device, typically used in situations requiring automatic closing or locking, such as kitchen cabinet doors and drawers.

[0017] The bottom of the front and rear ends of the middle plastic part's middle covering panel, the left side covering panel, and the right side covering panel are all provided with horizontal abutting surfaces for abutting against the inner wall of the outer covering panel, so as to prevent the top surface of the aforementioned covering panels from being higher than the outer covering panel when the car seat table is extended.

[0018] In the above solution: both the first covering panel and the second covering panel are composed of upper and lower covering plates. The upper and lower covering plates are snapped and fixed to the corresponding upper table frame assembly or lower table frame assembly. The covering plate located on the lower side of the upper table frame assembly and the covering plate located on the lower side of the lower table frame assembly have an overlapping area so that the bottom of the small table of the car seat can still be completely covered when it is extended.

[0019] The beneficial effects of this utility model are:

[0020] 1. In the extended state, the middle, left, and right covering panels of the middle plastic section are all connected to the top surfaces of the first and second covering panels, and their top surfaces are flush with the top surface of the outer covering panel. The entire tabletop is flat and smooth, providing passengers with a stable and comfortable platform for placing items, working, dining, or other activities. 2. In the retracted state, the first covering panel connects with the top surface of the second covering panel, and the middle, left, and right covering panels of the middle plastic section all sink down, perfectly concealing themselves within the outer covering panel. The entire tabletop has a flat and simple appearance, without any exposed complex mechanisms. 3. Operation is simple and convenient; users can switch between the tabletop states with a simple extension and retraction motion. Attached Figure Description

[0033] Figure 13 This is a structural diagram of all the covering plates. Detailed Implementation

[0034] like Figure 1 As shown in Figure 13, a car seat tray with telescopic function is mainly composed of a frame assembly, a middle plastic part covering panel 16, a left side covering panel 20, and a right side covering panel 19.

[0035] The frame assembly includes an upper table frame assembly 11 and a lower table frame assembly 10 that are slidably connected front to back. The front outer side of the lower table frame assembly 10 is covered by a first covering panel 12, and the rear outer side of the upper table frame assembly 11 is covered by a second covering panel 13. The top surfaces of the first covering panel 12 and the second covering panel 13 are flush, and when their top surfaces are joined, they can form an outer covering panel 14 that completely covers the frame assembly. The left covering panel 20 and the right covering panel 19 of the middle section plastic part are respectively contacted and connected to the left and right sides of the middle covering panel 16 of the middle section plastic part, and are respectively fixedly connected to the upper table frame assembly 11 by a push-to-close latch 24.

[0036] When the car seat tray table is extended, the middle plastic section covering panel 16, the left side covering panel 20, and the right side covering panel 19 are all in contact with the top surfaces of the first covering panel 12 and the second covering panel 13, and the top surfaces of all three are flush with the top surface of the outer covering panel 14. When the car seat tray table is retracted, the top surfaces of the first covering panel 12 and the second covering panel 13 are in contact, and the middle plastic section covering panel 16, the left side covering panel 20, and the right side covering panel 19 can all sink down, thus being hidden inside the outer covering panel 14.

[0037] Ideally, the lower tabletop frame assembly 10 has two first arc-shaped holes 25 arranged opposite each other on the left and right sides, with the first arc-shaped holes 25 extending counterclockwise from the front to the rear and upward. The upper tabletop frame assembly 11 has two second arc-shaped holes 26 arranged opposite each other on the left and right sides, with the second arc-shaped holes 26 extending counterclockwise from the front to the rear and downward, and their ends extending horizontally to the rear to form a strip-shaped hole segment. The front end of the middle section plastic part covering the middle panel 16 is rotatably connected to a first transverse pivot 17, which rotates and slides between the two first arc-shaped holes 25. The rear end of the middle section plastic part covering the middle panel 16 is rotatably connected to a second transverse pivot 18, which rotates and slides between the two second arc-shaped holes 26.

[0038] When the car seat tray is in the extended state, the first lateral pivot 17 is located at the end of the two first arc-shaped holes 25, and the second lateral pivot 18 is located at the front end of the two second arc-shaped holes 26, so that the middle covering panel 16, the left covering panel 20, and the right covering panel 19 of the middle plastic part are all in contact with the top surfaces of the first covering panel 12 and the second covering panel 13.

[0039] Pressing the left cover panel 20 and the right cover panel 19 of the middle section plastic component causes them to sink under the action of the Push-to-close Latch 24. At this time, pushing the upper table frame assembly 11 forward forces the first transverse pivot 17 to slide forward along the first arc-shaped hole 25, and at the same time forces the second transverse pivot 18 to slide backward along the second arc-shaped hole 26, so that the middle cover panel 16 of the middle section plastic component sinks automatically. When the first transverse pivot 17 slides to the front end of the first arc-shaped hole 25, continuing to push the upper table frame assembly 11 forward forces the second transverse pivot 18 to slide along the strip-shaped hole section of the second arc-shaped hole 26, thereby achieving the top face contact between the first cover panel 12 and the second cover panel 13, and thus hiding the middle cover panel 16, the left cover panel 20, and the right cover panel 19 of the middle section plastic component inside the outer cover panel 14.

[0040] This structure, by setting a first arc-shaped hole 25 and a second arc-shaped hole 26 with specific orientations, and a first transverse pivot 17 and a second transverse pivot 18 that cooperate with them, allows the middle section of the plastic part covering the panel 16 to move smoothly along a predetermined trajectory during the extension and retraction of the small table. This design ensures the smoothness of the extension and retraction operation, reduces jamming and shaking, and improves the user experience.

[0041] Ideally, the lower tabletop frame assembly 10 has two extending slots 2 on its left and right sides, and the two ends of the upper tabletop frame assembly 11 are slidably connected to the two slots 2 by bolts 22 and nuts 21, with two bolts 22 at each end and spaced apart. This design allows the upper tabletop frame assembly 11 to slide back and forth along the slots, thereby realizing the telescopic function of the small tabletop and meeting the user's needs for the length of the small tabletop in different usage scenarios.

[0042] Ideally, a rotating shaft mounting bracket 6 is welded onto the lower table frame assembly 10. The rotating shaft mounting bracket 6 has a U-shaped structure, with two first arc-shaped holes 25 respectively arranged at both ends of the rotating shaft mounting bracket 6. This structure is relatively simple, easy to process and manufacture, and makes it convenient to arrange the first arc-shaped holes 25.

[0043] Ideally, the lower table frame assembly 10 includes two lower table side panels 1 arranged opposite each other on the left and right. The front ends of the two lower table side panels 1 are connected by a front reinforcing bracket 4, and the rear ends of the two lower table side panels 1 are connected by a rear reinforcing bracket 5. The middle part of the front reinforcing bracket 4 and the middle part of the rear reinforcing bracket 5 are connected by a middle section reinforcing bracket 3, forming a stable frame structure. This structure can provide users with a safer and more reliable user experience.

[0044] Ideally, the rotating shaft mounting bracket 6 is welded to the middle of the middle of the reinforcing bracket 3, with two holes 2 respectively arranged on the two lower table side plates 1. The structure is simple and the arrangement is convenient.

[0045] Ideally, the upper table frame assembly 11 includes two upper table side panels 7 arranged opposite each other on the left and right, with the front ends of the two upper table side panels 7 connected by a middle reinforcing bracket 9, and two second arc-shaped holes 26 respectively arranged at the rear ends of the two upper table side panels 7. The structure is simple and easy to install.

[0046] A bushing 23 is provided between the upper table side panel 7 and the lower table side panel 1 on the same side, and the bushing 23 is fitted onto the bolt 22.

[0047] Ideally, each of the inner walls of the two upper table side panels 7 is provided with lugs 8. The left cover panel 20 of the middle plastic part is fixed to the left lug 8 by a push-to-close latch 24, and the right cover panel 19 of the middle plastic part is fixed to the right lug 8 by a push-to-close latch 24. Pressing the left cover panel 20 and the right cover panel 19 of the middle plastic part, i.e., pressing the push-to-close latch 24, will cause the left cover panel 20 and the right cover panel 19 of the middle plastic part to sink. Pressing the push-to-close latch 24 again will cause the left cover panel 20 and the right cover panel 19 of the middle plastic part to rise, so that they are flush with the outer cover panel 14 when the car seat table is extended.

[0048] Push-to-close Latch24 is existing technology and is an automatic spring-loaded locking device, typically used in situations requiring automatic closing or locking, such as kitchen cabinet doors and drawers.

[0049] The bottom of the front and rear ends of the middle plastic part covering panel 16, the left side covering panel 20 and the right side covering panel 19 are all provided with horizontal abutting surfaces for abutting against the inner wall of the outer covering panel 14, so as to prevent the top surface of the covering panel from being higher than the outer covering panel 14 when the car seat table is extended.

[0050] Preferably, both the first covering panel 12 and the second covering panel 13 are composed of upper and lower covering plates 15, which are snapped and fixed to the corresponding upper table frame assembly 11 or lower table frame assembly 10. The covering plate 15 located on the lower side of the upper table frame assembly 11 and the covering plate 15 located on the lower side of the lower table frame assembly 10 have an overlapping area, so that the bottom of the car seat table can still be completely covered when it is extended.
