Description

Technical Field

[0001] This utility model relates to a dual-pedal mechanism and a forklift. Background Technology

[0002] Currently, forklifts widely use dual-pedal mechanisms, where one pedal is responsible for forward acceleration and the other for reverse acceleration. In actual operation, these two pedals have an interlocking function, ensuring that only one pedal can be pressed at a time. The specific structure is usually a seesaw-like structure as shown in CN218345103U or CN214141440U, or a linkage-type elastic reset structure as shown in CN207328142U. These structures are complex, especially the structure in CN207328142U, where the seesaw has a short lever arm and multiple springs, making it difficult to reset after wear. In addition, these structures occupy a lot of space, especially the lateral space, making them difficult to adapt.

[0003] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a dual-pedal mechanism to solve the above-mentioned technical problems.

[0005] A dual-pedal mechanism includes a left pedal assembly and a right pedal assembly having an initial position. The left pedal assembly is rotatably configured about a first central axis and includes a rotatably configured first interlocking member and a first reset mechanism.

The first central axis and the second central axis are arranged parallel to each other and spaced apart. The first interlocking member includes a first toothed member, and the second interlocking member includes a second toothed member. The first toothed member and the second toothed member are kept in an engaged state. The first reset mechanism is used to reset the left pedal assembly to the initial position, and the second reset mechanism is used to reset the right pedal assembly to the initial position.

[0006] The first toothed component includes a first toothed surface, and the second toothed component includes a second toothed surface. The first toothed surface and the second toothed surface are in contact with each other, and both the first toothed surface and the second toothed surface are arc surfaces.

[0007] The first reset mechanism includes a first upper holding member, a first lower holding member, and a first elastic element disposed between the first upper holding member and the first lower holding member. A gap space is included between the first upper holding member and the first lower holding member. The first upper holding member includes a first upper holding surface facing the gap space, and the first lower holding member includes a first lower holding surface facing the gap space. The first elastic element is configured to have an elastic force that causes the first upper holding surface and the first lower holding surface to move in the direction of the gap space. The second reset mechanism includes a second upper holding member, a second lower holding member, and a second elastic element disposed between the second upper holding member and the second lower holding member.

[0008] The first interlocking component includes a first lever located within the interval space, comprising an upper side corresponding to the first upper pressing surface and a lower side corresponding to the first lower pressing surface, wherein the upper side is configured to abut against the first upper pressing surface and the lower side is configured to abut against the first lower pressing surface.

[0009] The dual-pedal mechanism further includes a bracket, which includes an upper limit guide hole and a lower limit guide hole. The first upper pressing member includes a first upper limit post passing through the upper limit guide hole, and the first lower pressing member includes a first lower limit post passing through the lower limit guide hole.

[0010] The extension direction of the first lever is opposite to the extension direction of the first toothed member.

[0011] When the left pedal assembly and the right pedal assembly are in their initial positions, the first pressing surface and the second pressing surface are parallel, and the first lever is in contact with both the first pressing surface and the second pressing surface.

[0012] The left pedal assembly further includes a left pedal and a first connecting rod disposed between the left pedal and the first interlocking member. The first connecting rod includes a first forward extension and a first outer extension, and the first forward extension and the first outer extension form an L-shape.

[0013] The right pedal assembly further includes a right pedal and a second connecting rod disposed between the right pedal and the second interlocking member. The second connecting rod includes a U-shaped member and a second extension portion, wherein the second extension portion is flush with the first extension portion. The U-shaped member includes a rear extension portion, a connecting portion, and a second front extension portion, wherein the rear extension portion is flush with the first front extension portion. The U-shaped member includes an enclosing space, and the second upper pressing member, the second lower pressing member, and the second elastic element are located within the enclosing space.

[0014] This utility model also provides a forklift, including the above-mentioned dual-pedal mechanism.

Detailed Implementation

[0018] Please refer to Figures 1-2This utility model provides a dual-pedal mechanism for controlling vehicles such as forklifts. The dual-pedal mechanism includes a left pedal assembly 10 and a right pedal assembly 20.

[0019] It is understood that the left pedal assembly 10 and the right pedal assembly 20 include an initial position, which refers to the position of the left pedal assembly 10 or the right pedal assembly 20 when it is not subjected to external force. Since the left pedal assembly 10 and the right pedal assembly 20 are interlocked, when the left pedal assembly 10 is in the initial position, the right pedal assembly 20 is also in the initial position, and when the right pedal assembly 20 is in the initial position, the left pedal assembly 10 is also in the initial position.

[0020] The left pedal assembly 10 is configured to rotate around a first central axis 1100 and includes a first interlocking member 11. Simultaneously, the right pedal assembly 20 is configured to rotate around a second central axis 2100 and includes a second interlocking member 21. The first central axis 1100 and the second central axis 2100 are parallel and spaced apart. The first interlocking member 11 includes a first toothed member 111, and the second interlocking member 21 includes a second toothed member 211. The first toothed member 111 and the second toothed member 211 are engaged, causing them to rotate in opposite directions during movement. In this embodiment, the first toothed member 111 includes a first toothed surface 1111, and the second toothed member 211 includes a second toothed surface 2111. The first toothed surface 1111 and the second toothed surface 2111 are in contact, thus maintaining the engagement between the first toothed member 111 and the second toothed member 211.

[0021] Furthermore, both the first tooth surface 1111 and the second tooth surface 2111 are arc surfaces. At the same time, the bending directions of the first tooth surface 1111 and the second tooth surface 2111 are opposite, so that the first interlocking member 11 and the second interlocking member 21 can move more smoothly and reduce the damage to the tooth root.

[0022] Furthermore, there are at least two first toothed members 111 and at least two second toothed members 211.

[0023] Furthermore, the left pedal assembly 10 includes a first central shaft 110, and the first interlocking member 11 includes a first central hole, and the first interlocking member 11 is sleeved on the first central shaft 110 through the first central hole. Similarly, the right pedal assembly 20 includes a second central shaft 210, and the second interlocking member 21 includes a second central hole, and the second interlocking member 21 is sleeved on the first central shaft 110 through the second central hole. It can be understood that the first central shaft 110 and the second central shaft 210 are arranged parallel and spaced apart, the first central axis 1100 is the axis of the first central shaft 110, and the second central axis 2100 is the axis of the second central shaft 210.

[0024] The left pedal assembly 10 further includes a first reset mechanism 12, which is configured to reset the left pedal assembly 10 to an initial position. The right pedal assembly 20 further includes a second reset mechanism 22, which is configured to reset the right pedal assembly 20 to an initial position.

[0025] In this embodiment, the first reset mechanism 12 includes a first upper pressing member 121, a first lower pressing member 122, and a first elastic element 123 disposed between the first upper pressing member 121 and the first lower pressing member 122. Specifically, the first upper pressing member 121 is rotatably configured via a first upper pivot 1212, and the first lower pressing member 122 is rotatably configured via a first lower pivot 1222. The rotation directions of the first upper pressing member 121 and the first lower pressing member 122 are opposite. A space 1200 is provided between the first upper pressing member 121 and the first lower pressing member 122. An upper pressing member 121 includes a first upper pressing surface 1211 facing the space 1200, and a first lower pressing member 122 includes a first lower pressing surface 1221 facing the space 1200. The first elastic element 123 is configured to have an elastic force that causes the first upper pressing surface 1211 and the first lower pressing surface 1221 to move toward the space 1200. The first interlocking member 11 includes a first lever 112 located within the space 1200 and includes an upper side corresponding to the first upper pressing surface 1211 and a lower side corresponding to the first lower pressing surface 1221.

[0026] Understandably, when the left pedal 14 is pressed to apply pressure, causing the first interlocking member 11 to rotate, the first lever 112 increases the spacing distance of the interval space 1200, thereby increasing the elastic force of the first elastic element 123. Understandably, when pressure is no longer applied to the left pedal 14, under the action of the elastic force of the first elastic element 123, the first lower pressing member 122 and the first upper pressing member 121 rotate, causing the first lever 112 to return to its original position, thereby causing the first interlocking member 11 to return to its original position and the entire left pedal assembly 10 to reset to its initial position. At the same time, because the first toothed member 111 of the first interlocking member 11 engages with the toothed member of the second interlocking member 21, the right pedal assembly 20 synchronously moves and resets to its initial position.

[0027] It is understood that the second reset mechanism 22 includes a second upper pressing member 221, a second lower pressing member 222, and a second elastic element 223 disposed between the second upper pressing member 221 and the second lower pressing member 222. The structure and arrangement of the second upper pressing member 221, the second lower pressing member 222, and the second elastic element 223 are basically the same as those of the first reset mechanism 12, and will not be described in detail here.

[0028] Furthermore, the dual-pedal mechanism also includes a bracket 30, which includes an upper limit guide hole 301 and a lower limit guide hole 302. The first upper pressing member 121 includes a first upper limit post 1213 passing through the upper limit guide hole 301, and the first lower pressing member 122 includes a first lower limit post 1223 passing through the lower limit guide hole 302. The lower position of the first upper pressing member 121 is limited by the first upper limit post 1213 and the upper limit guide hole 301, and the upper position of the first lower pressing member 122 is limited by the first lower limit post 1223 and the lower limit guide hole 302. Specifically, when the first lever 112 moves downward against the first lower pressing surface 1221, the first upper pressing member 121 is held in a predetermined position due to the position of the first upper limit post 1213 in the upper limit guide hole 301, while the first lower pressing member 122 can rotate downward. This increases the spacing of the interval space 1200 and the elastic force of the first elastic element 123. When the first lever 112 moves upward against the first upper pressing surface 1211, the first lower pressing member 122 is held in a predetermined position due to the position of the first lower limiting post 1223 in the lower limiting guide hole 302. At the same time, the first upper pressing member 121 can rotate upward, thereby increasing the spacing of the interval space 1200 and the elastic force of the first elastic element 123. In this way, the first interlocking member 11 can be reset under the elastic force of the first elastic element 123 when rotating clockwise or counterclockwise, so that the left pedal assembly 10 and the right pedal assembly 20 can be easily reset to their initial positions. In addition, the upper limiting guide hole 301 and the lower limiting guide hole 302 can also guide the movement of the first upper limiting post 1213 and the first lower limiting post 1223.

[0029] Furthermore, the extension direction of the first lever 112 is opposite to the extension direction of the first toothed member 111.

[0030] Furthermore, when the left pedal assembly 10 and the right pedal assembly 20 are in their initial positions, the first upper pressure holding surface 1211 and the first lower pressure holding surface 1221 are parallel to each other.

[0031] Furthermore, when the left pedal assembly 10 and the right pedal assembly 20 are in their initial positions, the first lever 112 is in contact with both the first upper pressing surface 1211 and the first lower pressing surface 1221.

[0032] Furthermore, the first elastic element 123 is a tension spring, and the two ends of the first elastic element 123 are respectively hung on the first upper pressing member 121 and the first lower pressing member 122 by a pair of hook-shaped members. Similarly, the second elastic element 223 is also a tension spring. In other embodiments, the first elastic element 123 and the second elastic element 223 can also be other types of elastic bodies, such as elastic zippers.

[0033] It is understood that the left pedal assembly 10 also includes a left pedal 14 and a first connecting rod 13 disposed between the left pedal 14 and the first interlocking member 11. It is understood that the first connecting rod 13 and the first interlocking member 11 can be fixedly connected, and the first connecting rod 13 and the left pedal 14 are also fixedly connected, so that when the left pedal 14 is pressed, the first connecting rod 13 drives the first interlocking member 11 to rotate around the first central axis 1100. Similarly, the right pedal assembly 20 also includes a right pedal 24 and a second connecting rod 23 disposed between the right pedal 24 and the second interlocking member 21. It is understood that the second connecting rod 23 and the second interlocking member 21 can be fixedly connected, and the first connecting rod 13 and the left pedal 14 are also fixedly connected.

[0034] In this embodiment, the first connecting rod 13 includes a first forward extension 131 and a first outer extension 132, and the first forward extension 131 and the first outer extension 132 form an L-shape.

[0035] Furthermore, the second connecting rod 23 includes a U-shaped member 231 and a second extension portion 232, wherein the second extension portion 232 is flush with the first extension portion 132. The meaning of "flush" is that when the left pedal assembly 10 and the right pedal assembly 20 are in the initial position, the front surface of the first extension portion 132 is coplanar with the front surface of the second extension portion 232, and the lower surface of the first extension portion 132 is coplanar with the lower surface of the second extension portion 232. Alternatively, when the first extension portion 132 and the second extension portion 232 each have a reference axis, the reference axis of the first extension portion 132 is collinear with the reference axis of the second extension portion 232.

[0036] Furthermore, when the left pedal assembly 10 and the right pedal assembly 20 are in their initial positions, the projection of the U-shaped member 231 on the horizontal plane is U-shaped. The U-shaped member 231 includes a rear extension 2311, a connecting portion 2312, and a second front extension 2313. The rear extension 2311 is flush with the first front extension 131. The U-shaped member 231 includes an enclosing space, within which the second upper pressing member 221, the second lower pressing member 222, and the second elastic element 223 are located. This arrangement makes the structure of the entire dual pedal assembly more compact, and the wear levels of the left pedal assembly 10 and the right pedal assembly 20 during use are more similar.

[0037] This utility model also provides a forklift, which includes the aforementioned dual-pedal mechanism.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
