DETAILED DESCRIPTION

[0022] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

[0023] A horizontal pedal mechanism meets two different displacement output requirements by respectively arranging two transmission stations of a toe and a heel, and meets the footstep operation requirement in a specific space by outputting different displacements in two directions. The horizontal pedal mechanism outputs displacement in a space with a small height and a long horizontal length.

[0024] As shown in Figure 1 , Figure 2 , the horizontal pedal mechanism comprises a support 1, a pedal, a pedal position adjusting mechanism 7, a position adjusting transmission mechanism 28 and a toe transmission mechanism 29.

[0025] The pedal position adjusting mechanism 7 is arranged on the support 1, and the pedal position adjusting mechanism 7 can adjust the position of the pedal.

[0026] The support 1 is provided with a central shaft 5, the pedal position adjusting mechanism 7 is connected with the central shaft 5, the position adjusting transmission mechanism 28 is connected with the pedal position adjusting mechanism 7, the central shaft 5 is rotationally connected with the support 1, and the central shaft 5 is fixedly connected with a first displacement output rocker arm 3. The front of the central shaft 5 is provided with a transmission shaft 18, the transmission shaft 18 is rotationally connected with the support 1, and the transmission shaft 18 is hingedly connected with a second displacement output rocker arm 24.

[0027] The pedal is provided with a toe transmission station and a heel transmission station, and the pedal is provided with a pedal plate. The toe transmission station is located at the front end of the pedal plate, and the heel transmission station is located at the rear end of the pedal plate. The toe transmission mechanism 29 is connected between the toe transmission station and the second displacement output rocker arm 24, and the position adjusting transmission mechanism 28 is connected between the heel transmission station and the first displacement output rocker arm 3.

[0028] When the toe of the driver presses the toe transmission station, the toe transmission mechanism 29 works and drives the second displacement output rocker arm 24 to rotate, and outputs the displacement of the pedal. When the heel of the driver presses the heel transmission station, the heel transmission station works and drives the first displacement output rocker arm 3 to rotate, and outputs the displacement of the pedal.

[0029] The rack is installed inside the footrest position adjusting mechanism 7, and the adjusting pull rod 6 is arranged outside. The adjusting pull rod 6 is connected with the clamping key matched with the rack at the position corresponding to the rack. By pulling the adjusting pull rod 6, the clamping key is inserted into different positions in the rack, so that the footrest position adjusting mechanism 7 can be locked at a certain position. When adjustment is needed, the clamping key is separated from the rack by pulling the adjusting pull rod 6. Under the action of the spring inside the footrest position adjusting mechanism 7, the adjusting pull rod 6 pulls the heel adjusting mechanism to the limit position on the operator side. At this time, the operator steps the footrest to the desired position, and then releases the adjusting pull rod 6 to lock the current position of the footrest. The specific design principle of the footrest position adjusting mechanism 7 is prior art, which will not be described here.

[0030] The positioning holes are arranged on the support 1 and the center shaft 5. During adjustment and inspection, the middle pin needs to pass through three holes at the same time for positioning, so as to ensure the reference position of the center.

[0031] Before driving, the height of the footrest is adjusted by the footrest position adjusting mechanism 7 according to the height of different drivers. When the driver is tall, the position of the footrest is appropriately lowered. When the driver is short, the position of the footrest is appropriately raised. During forward travel, the driver's toes step on the toe driving position of the footrest, driving the toe driving mechanism 29 to work. The toe driving mechanism 29 drives the second displacement output rocker arm 24 on the transmission shaft 18 to swing, outputting the forward displacement of the footrest. During backward travel, the driver's heels step on the heel driving position of the footrest, driving the position adjusting driving mechanism 28 to work. The position adjusting driving mechanism 28 drives the first displacement output rocker arm 3 on the center shaft 5 to swing, outputting the forward displacement of the footrest.

[0032] Due to the limited space of the footrest mechanism below the driver, by arranging the toe driving mechanism 29 and the position adjusting driving mechanism 28, the forward travel transmission and the backward travel transmission can be completed at the same time in a small specific space. The force transmission is stable, the operation is simple, and the demand for foot operation in a specific space is met.

[0033] Preferably, the footrest includes a left footrest 9 and a right footrest 16. The left footrest 9 and the right footrest 16 are symmetrically arranged on both sides of the footrest position adjusting mechanism 7. There are two groups of toe driving positions and heel driving positions. There are two groups of footrest transmission mechanisms and toe transmission mechanisms. Each group of toe driving positions is connected with a group of toe transmission mechanisms, and each group of heel driving positions is connected with a group of position adjusting driving mechanisms 28.

[0034] The two groups of position adjusting driving mechanisms 28 are arranged on both sides of the center shaft 5 and are meshed with each other.

[0035] When the left pedal 9 or the right pedal 16 is stepped on, one set of the position adjusting transmission mechanism 28 is driven to work, and then the other set of the position adjusting transmission mechanism 28 is driven to work through the meshing point, so that the displacement of the two heel transmission mechanisms is output at the same time.

[0036] As shown in Figure 2 , Figure 3 Preferably, the two sets of the position adjusting transmission mechanism 28 respectively include a first position adjusting transmission mechanism and a second position adjusting transmission mechanism.

Preferably, the first position adjusting transmission mechanism is connected to the right pedal 16, and the second position adjusting transmission mechanism is connected to the left pedal 9. When the right pedal 16 works, the first rocker arm 12 and the first pull rod 13 are sequentially swung, the first pull rod 13 drives the central shaft 5 to rotate through the connected pedal position adjusting mechanism 7, the central shaft 5 drives the first displacement output rocker arm 3 to swing, and the displacement transmission of the right pedal 16 is completed. In this process, the second rocker arm 15 swings synchronously. When the left pedal 9 works, the third rocker arm 10 and the second pull rod 8 are sequentially swung, and the central shaft 5 is driven to rotate through the pedal position adjusting mechanism 7, the central shaft 5 drives the other first displacement output rocker arm 3 to swing, and the displacement transmission of the left pedal 9 is completed. In this process, the fourth rocker arm 11 swings synchronously.

[0039] One end of the first rocker arm 12 and one end of the third rocker arm 10 are sleeved on the central shaft 5 and meshed with each other, so that the first position adjusting transmission mechanism and the second pedal transmission mechanism swing synchronously, and the first rocker arm 12 to the fourth rocker arm 11 form a parallelogram structure and work according to the parallelogram principle. Figure 4As shown, when the left pedal 9 is up, the right pedal 16 is down, in the first adjustment position; when the right pedal 16 is up, the left pedal 9 is down, in the second adjustment position; when the left pedal 9 and the right pedal 16 are at the same height, in the neutral position.

The pedal and the pedal are connected by a rotating shaft 20, such as the rotating shaft 20 between the right pedal 27 and the right pedal 16.

[0043] When the toe driving position on the pedal pedal is stepped on, the pedal pull rod 21 is first driven to work, and the force is transmitted to the input end of the pedal rocker arm 22, so as to drive the pedal rocker arm 22 to rotate, and the force is transmitted to the output end of the pedal rocker arm 22, and then the force is transmitted to the driving pull rod 23 by the output end of the pedal rocker arm 22, and then the force is transmitted to the second displacement output rocker arm 24 by the driving pull rod 23, and the second displacement output rocker arm 24 drives the output pull rod 25 to deflect, so as to output the displacement of the pedal to the rear.
