DETAILED DESCRIPTION

[0029] To better illustrate the purpose, technical solution, and advantages of this utility model, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] like Figures 1 to 5 The diagram illustrates a stable and easy-to-install car seat backrest tray according to an embodiment of the present invention. The car seat backrest tray includes a mounting base plate 10, a backrest body 20, a connecting rod assembly 30, and a tray body 40. The mounting base plate 10 is used to fix the tray body to the car seat back and provides space for the fixed installation of the backrest body 20 and the tray body 40. The backrest body 20 can be configured to the shape of the car seat backrest, making the car seat more aesthetically pleasing, and can also accommodate the tray body 40. The tray body 40 provides a place for the user to place items and is connected to the backrest body 20 via the connecting rod assembly 30. To make the tray body 40 more robust and stable, the connecting rod assembly 30 is typically configured in two sets, with each set of the connecting rod assembly 30 having two connecting rods.

[0031] To achieve the purpose of this utility model, this embodiment details that the linkage assembly 30 includes a back plate linkage base 31. The two sides of the linkage assembly 30 are respectively hinged to the back plate linkage base 31 and the table body 40. The back plate linkage base 31 is fixedly connected to the back plate body 20. The mounting base 10 is provided with a first mating hole 11 for fixing the mounting base 10 to the back of the car seat. The mounting base 10 is provided with a positioning hole 12, the back plate body 20 is provided with a positioning post 21, and the mounting base 10, back plate body 20, and back plate linkage base 31 are each provided with a second mating hole 50. The positioning hole 12 and the positioning post 21 cooperate with each other so that when the positioning post 21 is inserted into the positioning hole 12, the second mating holes 50 of the mounting base 10, back plate body 20, and back plate linkage base 31 are in a coaxial position, so as to connect the mounting base 10, back plate body 20, and back plate linkage base 31 together with bolts, nuts, and other fasteners.

[0032] It is worth noting that, at the factory, the tabletop body 40 is pre-fixed with the connecting rod assembly 30, and the end of the connecting rod assembly 30 is also pre-fixed to the back panel connecting rod base 31, which is pre-fixed to the back panel body 20. During transportation, the tabletop body 40 can be stored in the rear wall of the back panel body 20 through the connecting rod assembly 30. When installing the small table, the mounting base plate 10 is first fixed to the pre-drilled hole on the back frame using bolts and nuts through the first mating hole 11, thereby fixing the mounting base plate 10 and the car seat together. Then, the integrated back panel body 20 and tabletop body 40 are moved, and the positioning post 21 of the back panel body 20 is aligned and inserted into the positioning hole 12 of the mounting base plate 10, thereby initially fixing the integrated back panel body 20 and tabletop body 40 to the mounting base plate 10. The position of the back panel body 20 can be maintained by simple hand support, and the second mating holes 50 on the mounting base plate 10, the back panel connecting rod base 31, and the back panel body 20 are coaxial. Finally, the table body 40 is unfolded onto the back panel body 20 via the connecting rod assembly 30, exposing the positioning post 21 of the back panel connecting rod base 31. The bolts are then passed through the second mating hole 50 of the back panel connecting rod base 31, the second mating hole 50 of the back panel body 20, and the second mating hole 50 of the mounting base 10, thereby fixing the integrated back panel body 20 and table body 40 onto the mounting base 10, thus completing the installation of the small table behind the car seat.

[0033] Therefore, the small table on the back of the car seat of this utility model, by setting a positioning post 21 on the back panel body 20 and a positioning hole 12 on the mounting base plate 10, allows the back panel body 20 to be initially fixed to the mounting base plate 10. At the same time, the second mating holes 50 respectively set on the back panel connecting rod base 31, the back panel body 20 and the mounting base plate 10 will be coaxial with the positioning post 21 and the positioning hole 12. Then, with the help of bolts and other fasteners, the integrated back panel body 20 and table body 40 can be easily and quickly fixed to the mounting base plate 10. The table body 40 does not need to be disassembled for the convenience of the back panel body 20 installation, reducing the overall installation steps and saving time, effort and labor. After installation, the table body 40 is fixed to both the back panel body 20 and the mounting base plate 10, making the small table more stable.

[0034] For ease of installation, please refer to... Figure 2 and Figure 4Specifically, in this embodiment, the backplate body 20 is provided with two positioning posts 21, and the mounting substrate 10 is also provided with two positioning holes 12, the same number as the positioning posts 21. The two positioning posts 21 are located at the same horizontal position on the backplate body 20, and the two positioning holes 12 are also located at the same horizontal position on the mounting substrate 10. The relative distance between the two positioning posts 21 is equal to the relative distance between the two positioning holes 12. Furthermore, the relative position between the positioning hole 12 on the mounting substrate 10 and its second mating hole 50 is also the same as the relative position between the positioning post 21 on the backplate body 20 and its second mating hole 50.

[0035] For ease of installation, please refer to... Figure 2 and Figure 4 In this embodiment, specifically, the outer diameter of the positioning post 21 decreases from the inside to the end. Therefore, the end of the positioning post 21 can be formed with a pyramidal or conical tip. When the tip of the positioning post 21 is aligned with the positioning hole 12, continuing to push the backplate body 20 allows the positioning post 21 to be inserted into the positioning hole 12. To save material, the positioning post 21 can be configured in a cross shape.

[0036] For ease of installation, please refer to... Figure 2 and Figure 4 In this embodiment, the back panel body 20 is provided with a hook plate 22, which extends inward to the back panel body 20, which is positioned below the mounting base plate 10. During installation, the hook plate 22 of the back panel body 20 can be placed against the crossbeam of the car seat back, and the position can be finely adjusted to align the positioning post 21 with the positioning hole 12, thus making installation easier.

[0037] For ease of installation, please refer to... Figure 2 and Figure 4 In this specific embodiment, the second mating hole 50 of the mounting base 10 is configured as a screw hole. The bolt passes through the second mating hole 50 of the back plate connecting rod base 31 and the second mating hole 50 of the back plate body 20 in sequence, and can be directly connected and fixed to the threaded second mating hole 50 on the mounting base 10.

[0038] To secure the tabletop and back panel, refer to... Figure 5Specifically, in this embodiment, the back panel body 20 and the back panel connecting rod base 31 are each provided with a third mating hole 60. When the third mating holes 60 of the back panel body 20 and the back panel connecting rod base 31 are in a coaxial position, the second mating holes 50 of the back panel body 20 and the back panel connecting rod base 31 are also in a coaxial position, so as to connect the back panel body 20 and the back panel connecting rod base 31 to each other with bolts and nuts, thereby realizing the fixation of the tabletop and the back panel, and the positioning of the second mating hole 50. Specifically, in this embodiment, a positioning groove 23 is provided on the outer side of the back panel body 20. The back panel connecting rod base 31 is embedded into the positioning groove 23, and one third mating hole 60 is configured. Thus, the positioning groove 23 can play an auxiliary role in fixing and installation, and a single bolt can achieve the fixing effect. It is worth noting that the tabletop body 40 and the back panel connecting rod base 31 are already connected to each other at the factory, and the back panel body 20 and the back panel connecting rod base 31 are already connected to each other, so there is no need to disassemble them during installation.

[0039] For a more compact small table, refer to Figure 2 and Figure 4 In this embodiment, specifically, the mounting base 10 is provided with a notch 13 so that the back plate connecting rod base 31 extends from the outside to the inside of the mounting base 10. The notch 13 can avoid the installation of the connecting rod assembly 30, thereby allowing the table body 40 to be better embedded into the back plate body 20.

[0040] For a more compact small table, refer to Figure 1 and Figure 5 Specifically, in this embodiment, a first groove 24 is provided on the outer side of the back panel body 20. Two second grooves 25 are provided within the first groove 24, and a third groove 26 is provided within each of the second grooves 25. The first groove 24 matches the tabletop body 40, allowing the tabletop body 40 to be displaced into the first groove 24 via the movement of the connecting rod assembly 30. Each connecting rod assembly 30 is fixed within its corresponding third groove 26 via a back panel connecting rod base 31. The second mating hole 50 and the third mating hole 60 are located within the third groove 26. The back panel body 20 also includes a cover plate 27, which matches and covers the second grooves 25, thereby concealing the back panel connecting rod base 31 and exposing only the connecting rod.

[0041] The above embodiments mainly describe the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
