Description

Technical Field

[0001] The present invention relates to the technical field of projector equipment, and in particular to a vibration absorbing component of a projector and a use method thereof. Background Art

[0002] Currently, projectors on the market are generally installed at high places. After installation, the bottom may sometimes be hit by other objects or affected by external forces, which will cause vibrations and affect the internal parts of the projector.

[0003] To this end, the Chinese patent with publication number "CN213954251U" announced "a vibration reduction device for a projector", whose main structure includes a fixing seat, a groove one, a sponge pad, a groove two, a projector, a threaded groove, a threaded rod, a fixing block, a cutout, a sponge block, a connecting rod and a connecting block. The above device reduces the vibration between the outer shell and the internal components of the projector through the fixing seat, the threaded rod and the fixing block and other components located outside the projector. In addition, due to the elasticity between the sponge block and the sponge pad, the projector will not directly touch other hard objects, thereby reducing the vibration of the projector relative to other objects, thereby reducing the vibration of the projector, and thereby reducing the impact on the internal parts of the projector.

[0004] It is obvious that the above-mentioned vibration reduction device for the projector relies on the elasticity between the sponge block and the sponge pad as the vibration reduction medium. It can only achieve the function of buffering and shock absorption, and cannot absorb kinetic energy. In other words, the kinetic energy caused by impact or vibration will act on the inside of the projector to the maximum extent, and there is still a great safety hazard. Summary of the invention

[0018] 2. By setting up a tooth-type kinetic energy conversion mechanism, when a longitudinal relative displacement occurs between the lower mounting base and the upper mounting base, the longitudinal rack will be driven to move.

First, the bottom of the lower mounting base 1 is fixedly connected to the top of a supporting frame for support, and then the top of the upper mounting base 2 is fixedly connected to the bottom end of the projector electronic device. At the same time, the supporting frame is fixedly installed on the ground or the mounting base.

When a longitudinal relative displacement occurs between the lower mounting base 1 and the upper mounting base 2, the longitudinal rack 66 will be driven to move. Since the longitudinal rack 66 and the gear 64 are meshed through teeth, the gear 64 will drive the rotating wheel 65 to move, thereby converting the kinetic energy from the lower mounting base 1 and the upper mounting base 2 into the kinetic energy required for the rotation of the rotating wheel 65, thereby realizing the conversion between kinetic energy.

[0032] For the specific structure of the tooth-type kinetic energy conversion mechanism 6, please refer to Figure 5 , including two support bases 61 fixedly mounted on the upper surface of the lower mounting base 1 and a No. 1 fixing plate 67 fixedly mounted on the lower surface of the upper mounting base 2, each of the two support bases 61 is provided with a No. 1 shaft body mounting hole 62, and a rotatable horizontal rotating shaft 63 is mounted in the two No. 1 shaft body mounting holes 62 through bearings, a gear 64 that can rotate with the horizontal rotating shaft 63 is mounted in the middle of the horizontal rotating shaft 63, and a rotating wheel 65 is fixedly mounted on the shaft located on both sides of the gear 64 of the horizontal rotating shaft 63, The bottom surface of the No. 1 fixed plate 67 is provided with a longitudinal rack 66 which is an integral structure therewith.

The bottom of the longitudinal rack 66 is provided with a lower limit plate 68 which is an integral structure therewith and can prevent the longitudinal rack 66 and the gear 64 from being separated. In order to have a sufficient range of motion, it is necessary that when the lower mounting base 1 and the upper mounting base 2 are installed accordingly, under the action of gravity, the gear 64 is in the middle area of ​​the longitudinal rack 66.

[0033] In order to convert the kinetic energy required for the rotation of the rotating wheel 65 into heat energy between the arc-shaped friction plate 78 and the rotating wheel 65, thereby achieving the effect of absorbing kinetic energy, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , it is necessary to set up two buffer-type friction mechanisms 7, which are provided with an arc-shaped friction plate 78 that abuts against the bottom of the rotating wheel 65 and generates friction and heat when the rotating wheel 65 rotates, and a No. 1 coil spring 76 that generates upward elastic pressure on the arc-shaped friction plate 78.

[0035] To achieve the effect of cushioning support, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 , it is necessary to set up an elastic buffer mechanism 8, inside which are arranged a No. 2 coil spring 89 that elastically supports the lower mounting base 1 and the upper mounting base 2, as well as a piston plate 86 and a No. 2 gas flow limiting hole 84 that can control the internal gas flow speed. Once the external environment vibrates, the vibration will be transmitted along the support frame to the projection electronic component. At this time, a longitudinal relative displacement will occur between the lower mounting base 1 and the upper mounting base 2, and the No. 2 coil spring 89 will undergo an adaptive change to play a necessary buffering effect.

At this time, a longitudinal relative displacement will occur between the lower mounting base 1 and the upper mounting base 2, and the No. 2 coil spring 89 will undergo an adaptive change to achieve the necessary buffering effect. At the same time, the piston plate 86 will be displaced inside the active cavity 83 of the No. 2 longitudinal component, and the air will adaptively flow along the No. 2 gas flow limiting hole 84 and the No. 2 rod body through-hole 85. Since the No. 2 gas flow limiting hole 84 limits the flow of gas, it can prevent The phenomenon of excessive movement of the stopping parts is prevented, and the necessary gas buffering effect is provided; Step 3: When longitudinal relative displacement occurs between the lower mounting base 1 and the upper mounting base 2, the longitudinal rack 66 will be driven to move. Since the longitudinal rack 66 and the gear 64 are meshed through teeth, the gear 64 will drive the rotating wheel 65 to move, thereby converting the kinetic energy from the lower mounting base 1 and the upper mounting base 2 into the kinetic energy required for the rotation of the rotating wheel 65, thereby realizing the conversion between kinetic energy; Step 4: When the rotating wheel 65 rotates, relative friction will occur between the arc-shaped friction plate 78, thereby converting the kinetic energy required for the rotation of the rotating wheel 65 into heat energy between the arc-shaped friction plate 78 and the rotating wheel 65, thereby achieving the effect of absorbing kinetic energy.

At the same time, the piston plate (86) will be displaced inside the No. 2 longitudinal component active cavity (83), and the air will adaptively flow along the No. 2 gas flow limiting hole (84) and the No. 2 rod body perforation (85). Due to the No. 2 gas flow limiting hole (84) limiting the flow of gas, it can prevent the components from moving too fast, providing the necessary gas buffering effect. Step 3: When longitudinal relative displacement occurs between the lower mounting base (1) and the upper mounting base (2), the longitudinal rack (66) is driven to move. Since the longitudinal rack (66) and the gear (64) are meshed with each other through teeth, the gear (64) drives the rotating wheel (65) to move, thereby converting the kinetic energy from the lower mounting base (1) and the upper mounting base (2) into the kinetic energy required for the rotating wheel (65) to rotate, thereby realizing the conversion between kinetic energy; Step 4: When the rotating wheel (65) rotates, relative friction occurs between the rotating wheel (65) and the arc-shaped friction plate (78), thereby converting the kinetic energy required for the rotation of the rotating wheel (65) into heat energy between the arc-shaped friction plate (78) and the rotating wheel (65), thereby achieving the effect of absorbing kinetic energy.
