Low noise pop-up pedal device

The present invention relates to a footrest device, and more particularly to a low noise pop-up footrest device.

For the convenience of the rear seat passengers, the general locomotive will have a rear footrest on both sides of the vehicle body for the passenger's foot to be placed, and the rear footrest is mostly used by the passenger by hand or foot. It is more inconvenient to use it when it is opened.

Referring to Figures 1 and 2, there is a conventional automatic opening device for a locomotive of a locomotive. The locomotive has a vehicle body (not shown), and the automatic opening device for the pedal includes two devices disposed on both sides of the vehicle body. The pivoting seat 11 and the two foot levers 12 respectively pivotally connected to the pivoting seats 11 and a wire device 13 connected to the pivoting seats 11 .

Each of the pivoting seats 11 includes a housing 111, a shaft 112 disposed on the housing 111, a slider 113 slidably disposed in the housing 111, and a compression spring 114. Each of the sliders 113 has a protruding portion 1131 protruding from the corresponding housing 111, and the opposite ends of the compression springs 114 are respectively abutted against the corresponding slider 113 and the housing 111. And having an elastic restoring force that causes the protrusions 1131 to protrude outside the housings 111.

Each of the pedals 12 includes a rod body 121, a through hole 122 extending through the rod body 121 and sleeved on the corresponding shaft 112, a torsion spring 123, and a recess formed in the rod body 121. The card slot 124 of the surface. The rod bodies 121 are pivotally connected to the pivoting seats 11 by the through holes 122, and are rotatable between a folding position and an opening position. In the folding position, the rods are rotated. The bodies 121 are substantially parallel to one another, and in the open position, the rod bodies 121 are unscrewed in a direction opposite to each other as shown in FIG. The torsion springs 123 are respectively looped on the shafts 112, and the opposite ends are respectively fastened to the corresponding shafts 112 and the rod body 121, and the torsion springs 123 are constant to make the rod bodies 121 returns to the elastic restoring force of the open position.

The wire device 13 includes a main line portion 131 and two tap portions 132 extending outward from the main line portion 131. The tap portions 132 are respectively connected to the sliders 113. At the folding position, the protruding portions 1131 of the sliders 113 are engaged in the card slots 124, so that the rod bodies 121 can be stably maintained at the folding position. Pulling the main line portion 131 can drive the tap portions 132, and further moving the sliders 113 in the direction indicated by the arrow in FIG. 1 and compressing the compression springs 114, and the protrusions 1131 are returned to the same. Inside the housing 111, the elastic restoring forces of the torsion springs 123 then function, causing the lever bodies 121 to automatically rotate to the open position and for the passenger's feet to be placed. By pulling the main line portion 131, the rod bodies 121 can be rotated to the open position, so that the passenger does not have to open the rod bodies 121 by themselves, which is more convenient in use.

However, since the rod bodies 121 are rotated to the open position by the elastic restoring force of the torsion springs 123, the rotational force is large, and the rod bodies 121 hit the shells at the moment when they reach the open position. The body 111 emits an audible sound, and in addition, the sliders 113 are pulled back into the housings 111. At the time of the point, it is inevitable that due to the error of the line length of the tapping portion 132, or slightly unsynchronized by the internal structure of the vehicle body, the time when the rod body 121 is unscrewed and hits the casing 111 Slightly different, so that the impact sound is not synchronized, may give people a poor perception of the texture, so the aforementioned locomotive pedal automatic opening device still has room for improvement.

Accordingly, it is an object of the present invention to provide a low noise pop-up footrest device that reduces impact noise.

Therefore, the low-noise pop-up pedal device of the present invention is suitable for being mounted on a locomotive, the locomotive includes a frame, and a mount coupled to the frame. The low noise pop-up pedal device includes a foot unit.

The pedal unit includes a fixed seat, a footrest, and a lowering member. The fixing base is coupled to the mounting base, the fixing base comprises a body, a base wall coupled to one side of the body, a cover plate detachably disposed on the other side of the body, and a base wall facing away from the base The cover extends a shaft column for pivoting the foot lever. The foot lever is pivotally disposed on the fixing seat, and is rotatable relative to the fixing seat between a folding position and an ejecting position. In the folding position, the foot lever is close to the frame, and When the position is ejected, one end of the foot lever is away from the frame. The sound reducing member is located between the fixing seat and the foot bar, and the sound reducing member is bent inwardly by the cover plate and attached to the body.

On the other hand, the sound-reducing member of the present invention may also be a bump or a ridge formed by the cover plate inwardly or made of an elastic material, and disposed on the body.

The effect of the present invention is that by the setting of the sound reducing member, when the pedal is When the rod is ejected, it will not directly hit the fixing seat, which can reduce the impact sound, and the look and feel is better when used.

As shown, the cover plates 43 are respectively inwardly protruded, and the buffer protection effect can also be achieved. Furthermore, the number of the pedal units 3 is two, and is respectively coupled to the mounting bases 22 on the left and right sides, and the actuation of the pedal units 3 is controlled by the two sub-wirings 71 of the wire device 7, respectively. In order to facilitate the placement of the two legs of the rear seat passenger, but of course, depending on the special needs, the pedal unit 3 may also have only one, and the wire device 7 only includes the main line 72 to control the operation of the single pedal unit 3, Not limited to this.

The low-noise pop-up foot device of the present invention is disposed between the footrests 5 and the fixed seats 4 by the sound-reducing members 6, so that when the foot-operating bars 5 are ejected to the ejecting position When it does not directly collide with the fixing seats 4, it causes an audible sound. In addition, since the force of the pedals 5 ejecting and striking the sound-reducing members 6 is relatively large, the combination between the mounts 22 and the mounts 4 is inevitably loosened after a long period of use, The design of the axle posts 44 protruding from the cover plates 43 against the second side plates 222 prevents the sound generated by the collision between the cover plates 43 and the second side plates 222 due to looseness. Therefore, the noise generated during use can also be reduced, thereby improving the texture during use.

Referring to Figure 10, a second preferred embodiment of the low noise pop-up foot device of the present invention is substantially the same as the first preferred embodiment, except that each of the sound-reducing members 6 is made of an elastic material. A ridge is formed and attached to one of the bodies 41.

In the preferred embodiment, the sound reducing members 6 are made of elastic rubber. And the ridges are of course, but of course the sound-reducing members 6 may also be in the form of bumps, or attached to the footrest 5 as shown in FIG. 11, and since the pedals 5 are Rotating around the shaft column 44 of the fixing base 4, when the sound reducing members 6 are attached to the footrest 5, it should be noted that when the footrests 5 are in the ejecting position, the sound reducing members 6 The position needs to be as shown in Fig. 12, and it can be resisted on the fixed seats 4.

In addition to the advantages of the first preferred embodiment, the present preferred embodiment is made of an elastic material, so that the noise damping effect is better.

In summary, the low-noise pop-up pedal device 3 of the present invention, by the design of the sound-reducing members 6, prevents the pedal members 5 from directly hitting the fixed-points when they are ejected to the ejecting position. Block 4, thus reducing the impact noise. And the axles 44 protrude from the cover plates 43 and abut against the design of the second side plates 222, so as to avoid the vibration when the pedal bars 5 hit the sound-reducing members 6, which may cause the fixing bases. 4 The sound that is struck by the impact between the mounts 22 and the mount 22 also reduces noise and improves the texture of the use. Furthermore, the sound-reducing members 6 may also be ridges or bumps made of an elastic material, and may be attached to the body 41 of the fixing base 4 or the footrest 5, thereby damping noise. The above effect is better, so the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
