[0019] Specifically, the telescopic rotary vehicle-mounted table device of the embodiment is fixedly installed on the back of the automobile seat 1; when the vehicle-mounted table device is not used, that is, the flexible pull rope 4 is not wound on the storage roller 3, the flexible pull rope 4 is in a relaxed state, the first table plate 61 and the second table plates 62 and the adjacent two second table plates 62 are connected by the tension of the buffer springs 63 themselves, so that the first table plate 61 and the second table plates 62 and the adjacent two second table plates 62 are in a flexible connection, which is convenient for storage and can reduce the harm to the user.

[0020] When the vehicle-mounted table device needs to be used, the storage roller 3 is rotated, so that the flexible pull rope 4 is wound on the storage roller 3, and the first table plate 61 moves towards the storage roller 3 until the flexible pull rope 4 is completely tensioned, and the buffer spring 63 is in a completely compressed state, so that the first table plate 61 and the second table plates 62 and the adjacent two second table plates 62 are rigidly connected, thereby facilitating the user to use.

[0021] The telescopic rotary vehicle-mounted table device of the embodiment is fixedly installed on the back of the automobile seat 1; when the vehicle-mounted table device is not used, that is, the flexible pull rope 4 is not wound on the storage roller 3, the flexible pull rope 4 is in a relaxed state, the first table plate 61 and the second table plates 62 and the adjacent two second table plates 62 are connected by the tension of the buffer springs 63 themselves, so that the first table plate 61 and the second table plates 62 and the adjacent two second table plates 62 are in a flexible connection, which is convenient for storage and can reduce the harm to the user.

[0022] The telescopic rotary vehicle-mounted table device provided by the embodiment has the storage roller 3 provided with a storage groove 31 for storing the flexible pull rope 4. Through the above arrangement, the flexible pull rope 4 can be conveniently wound and stored.

[0027] When storage is needed, the unlocking pin 91 pushes the one-way fixed block 82 to overcome the action of the fixed spring 81 through the unlocking slope 83, so as to separate from the one-way groove 32. At this time, under the action of the gravity of the first table plate 61, the gravity of the second table plate 62, the gravity of the baffle 5 and the reset action of the flexible pull rope, the storage roller 3 automatically resets and rotates, so as to restore the overall connecting structure to a flexible connection, thereby facilitating storage.
