[0002] In the development process of modern cinemas, the audience's demand for the immersive feeling of watching movies is continuously increasing. Traditional fixed seats cannot meet the audience's desire to experience the movie scenes personally. When watching action, science fiction, and adventure movies, the audience expects the seats to have lifting and other motion feedbacks with the plot ups and downs to simulate different scenes and enhance the sense of substitution. At the same time, the competition in the cinema market is intensifying. An immersive cinema with liftable seats can become a selling point to attract audiences, which helps to increase box office and market share. The development of mechanical technology provides a basis for this. The miniaturized and efficient electric push rod technology can achieve large thrust output in a small space and has precise stroke control, and can be used for seat lifting and meet the requirements of the structural space. The advanced bearing technology ensures the stability and low friction of the rotation of the horizontal axis. The high-precision shaft processing technology guarantees the assembly accuracy of components. The mature ratchet and engagement technology precisely controls the rotation position of components through the engagement of the engagement block and the ratchet teeth. The ratchet helical tooth design meets special motion requirements. From the perspective of ergonomics, the seat lifting can adapt to audiences of different heights to obtain a better view and a comfortable posture. In terms of safety, during the seat lifting process, corresponding requirements also need to be met. Content of the Utility Model

[0024] Skeleton 1

[0025] The skeleton 1 is the basic framework of the entire seat lifting structure. It plays a role in supporting and connecting other components. The seat 2 is fixedly installed on the skeleton 1, which indicates that the skeleton 1 has to bear the weight of the seat and passengers, and provides a stable basic platform for the installation of other components.

[0026] Bearing seat 3

[0027] The bearing seat 3 installed on the skeleton 1 provides rotational support for the transverse shaft 4. The interior of the bearing seat 3 is rotatably connected to the transverse shaft 4, enabling the transverse shaft 4 to rotate flexibly within the bearing seat 3. This rotational connection is the key to realizing the relative movement of certain components in the entire structure.

[0028] Transverse shaft 4

[0029] The transverse shaft 4 penetrates through the bearing seat 3 and is fixedly sleeved with a square block 5 outside. The rotation of the transverse shaft 4 can drive the square block 5 to rotate together. It is an important component for transmitting power and realizing motion conversion. The transverse shaft 4 is also fixedly connected to the rotating member 7, and the rotating member 7 is rotatably connected to the electric push rod 8. This means that the telescopic movement of the electric push rod 8 can be converted into the rotational movement of the transverse shaft 4 through the rotating member 7.

[0030] Square block 5

[0031] The square block 5 is sleeved outside the transverse shaft 4, and a guardrail 6 is fixedly connected to its outside. When the transverse shaft 4 rotates, the square block 5 rotates accordingly, thereby driving the guardrail 6 to move. The square block 5 plays a role in connecting the transverse shaft 4 and the guardrail 6, and transmits the rotational movement of the transverse shaft 4 to the guardrail 6 to achieve the movement related to the seat lifting of the guardrail 6.

[0032] Guardrail 6

[0033] The guardrail 6 is fixedly connected to the square block 5, and its movement is associated with the rotation of the square block 5. Although the specific function of the guardrail 6 during the seat lifting process is not clearly stated, it may be related to the safety protection of passengers and the auxiliary positioning during the seat lifting process, etc.

[0034] Rotating part 7

[0035] One end of the rotating part 7 is fixedly connected to the transverse shaft 4, and the other end is rotatably connected to the electric push rod 8. It plays a role in converting the linear movement of the electric push rod 8 into the rotational movement of the transverse shaft 4, and is a key component to realize the drive of the entire structure by the electric push rod 8.

[0036] Electric push rod 8

[0037] One end of the electric push rod 8 is rotatably connected to the frame 1, and the other end is rotatably connected to the rotating part 7. As a power source, the electric push rod 8 drives the rotating part 7 through telescopic movement, thereby driving the transverse shaft 4 to rotate, and finally realizing the movement of the components associated with the transverse shaft 4. It is an important driving component to control the actions related to the seat lifting.

[0038] Mounting plate 9

[0039] The mounting plate 9 mounted on the frame 1 provides a mounting position for the shaft seat 10. It is a basic component for constructing another part of the movement mechanism in the seat lifting structure, and provides a stable mounting foundation for the shaft seat 10 and the subsequent components connected thereto.

[0040] Shaft seat 10

[0041] The shaft seat 10 mounted on the mounting plate 9 is used for rotatably connecting the hand lever 11. The shaft seat 10 provides a rotational support point for the hand lever 11, enabling the hand lever 11 to rotate around the shaft seat 10.

[0042] Hand lever 11

[0043] One end of the hand lever 11 is rotatably connected to the shaft seat 10, and the other end is fixedly connected to the connecting block 12. The rotation of the hand lever 11 can drive the connecting block 12 to move.

[0044] Connecting block 12

[0045] The connecting block 12 is fixedly connected to the hand lever 11, and at the same time, a fixed rod 13 is fixedly connected to the connecting block 12. The connecting block 12 serves to connect the hand lever 11 and the fixed rod 13, and transmits the movement of the hand lever 11 to the fixed rod 13.

[0046] Fixed rod 13

[0047] A spring 14 is sleeved on the fixed rod 13, and a linkage block 15 is fixedly installed. The fixed rod 13 serves to connect and transmit movement between the connecting block 12 and the linkage block 15. At the same time, the spring 14 is sleeved on the fixed rod 13 and interacts with the linkage block 15, participating in the movement and force transmission process of the entire structure.

[0048] Spring 14

[0049] One end of the spring 14 abuts against the linkage block 15, and the other end is on the mounting plate 9. The spring 14 serves as a buffer, a reset device, or an auxiliary force transmission device in this structure. When the linkage block 15 moves, the spring 14 will be compressed or stretched, storing or releasing energy to achieve functions such as the stable movement of certain components or returning to the initial position.

[0050] Linkage block 15

[0051] The linkage block 15 is fixedly installed on the fixed rod 13, one end interacts with the spring 14, and the other end is fixedly connected to the engaging block 16. The linkage block 15 transmits the movement of the fixed rod 13 to the engaging block 16, and under the assistance of the spring 14, controls the movement of the engaging block 16.

[0052] Engaging block 16

[0053] The engaging block 16 is fixedly connected to the linkage block 15 and engages with the ratchet wheel 17 through teeth. The engagement relationship between the engaging block 16 and the ratchet wheel 17 can control the rotation of the ratchet wheel 17, and thus control the movement state of the components associated with the ratchet wheel 17, serving to lock or limit the movement of certain components.

[0054] Ratchet wheel 17

[0055] The ratchet wheel 17 is installed on the outside of the square block 5, and helical teeth are provided on a quarter circular arc surface. The engagement relationship between the ratchet wheel 17 and the engaging block 16, combined with its own helical tooth structure, can accurately control the rotation angle or position of the square block 5, thus serving to position and limit movement in the seat lifting structure.

[0056] Working principle:

[0057] When the electric push rod 8 expands and contracts, since one end of the electric push rod 8 is rotatably connected to the framework 1 and the other end is rotatably connected to the rotating member 7, the expansion and contraction movement of the electric push rod 8 will be converted into the rotational movement of the rotating member 7.

[0058] The rotating member 7 is fixedly connected to the transverse shaft 4, and the transverse shaft 4 passes through the bearing block 3 and rotates within the bearing block 3. Therefore, the rotation of the rotating member 7 drives the rotation of the transverse shaft 4.

[0059] A square block 5 is fixedly sleeved outside the transverse shaft 4, and a guardrail 6 is fixedly connected to the outside of the square block 5. When the transverse shaft 4 rotates, the square block 5 rotates accordingly, thereby driving the guardrail 6 to move up and down.

[0060] Manually operate the hand lever 11, and the hand lever 11 rotates around the shaft seat 10. The shaft seat 10 is installed on the mounting plate 9, and one end of the hand lever 11 is fixedly connected to the connecting block 12. Therefore, the rotation of the hand lever 11 drives the movement of the connecting block 12.

[0061] A fixing rod 13 is fixedly connected to the connecting block 12, and a linkage block 15 is fixedly installed on the fixing rod 13. Therefore, the movement of the connecting block 12 is transmitted to the fixing rod 13 and the linkage block 15.

[0062] One end of the linkage block 15 is fixedly connected to the engaging block 16, and when the linkage block 15 moves, the engaging block 16 moves accordingly.

[0063] The engaging block 16 is connected to the ratchet wheel 17 by teeth, and the ratchet wheel 17 is installed on the outside of the square block 5. When the engaging block 16 moves, the engaging state with the ratchet wheel 17 will change.

[0064] The ratchet wheel 17 has helical teeth on a quarter-circular arc surface. This special tooth profile structure enables the engagement between the engaging block 16 and the ratchet wheel 17 to precisely control the rotation position of the square block 5. For example, when the engaging block 16 engages with the teeth of the ratchet wheel 17, the rotation of the square block 5 can be blocked, thereby realizing the positioning of the components associated with the square block 5.

[0065] In this process, the spring 14 plays an important auxiliary role. One end of the spring 14 abuts against the linkage block 15, and the other end is on the mounting plate 9. When the linkage block 15 moves, the spring 14 will be compressed or stretched.

[0066] As Figure 3 shown, in some embodiments, one end of the electric push rod 8 is rotatably connected to the frame 1; when the electric push rod 8 expands and contracts, since one end is rotatably connected to the frame 1, this provides a stable support point for the electric push rod 8. The frame 1, as the basic frame of the entire seat structure, can withstand the reaction force generated when the electric push rod 8 works.

[0067] As Figure 4As shown, in some embodiments, one end of the spring 14 abuts against the linkage block 15, and the other end of the spring 14 is on the mounting plate 9; when manually operating the hand lever 11, the movement of the linkage block 15 will be caused. Since one end of the spring 14 abuts against the linkage block 15, when the linkage block 15 suddenly moves under force, the spring 14 will be compressed or stretched.

[0068] As Figure 4 shown, in some embodiments, the ratchet 17 is mounted on the outside of the square block 5; in the layout of the entire seat lifting structure, mounting the ratchet 17 on the outside of the square block 5 is a reasonable way to utilize space. It can effectively achieve the control function of the rotation of the square block 5 without occupying too much extra space. This layout helps to maintain the compactness of the entire seat structure while meeting the functional requirements of seat lifting and positioning.

[0069] As Figure 5 shown, in some embodiments, the ratchet 17 has helical teeth on a quarter-circular arc surface; the helical tooth structure on the quarter-circular arc surface is sufficient to meet the control requirements of seat-related components in critical positions or specific operation stages, and can simplify the structural design and operation process.

[0070] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
