Description

Technical Field

[0001] This disclosure relates to the field of vehicle side pedal technology, and in particular to a rotary drive pedal mechanism. Background Technology

[0002] With the rapid development and widespread adoption of automobiles, users are increasingly demanding electric running boards. In particular, electric running boards are becoming more prevalent in vehicles with higher chassis, such as SUVs and off-road vehicles. Furthermore, electric running boards are also becoming an indispensable feature for high-end limousines and other vehicles with special purposes.

[0003] Most existing electric running boards in vehicles are four-link rotating running boards. However, existing electric running boards have the following drawbacks: relatively complex structure; high Z-axis extension, affecting vehicle passability; and unsightly Z-axis rotating extension.

[0004] Therefore, it is necessary to provide a new type of pedal mechanism to adapt to the increasingly congested urban roads of today. Utility Model Content

[0005] In view of the above-mentioned status quo of pedal mechanisms according to the prior art, one of the objectives of this disclosure is to provide a rotary drive pedal mechanism that solves at least one of the above-mentioned existing problems.

[0006] This objective is achieved by disclosing a rotary-driven pedal mechanism of the following form. The rotary-driven pedal mechanism includes a pedal and a drive unit, etc. The drive unit is connected to both the vehicle body and the pedal, and is configured to drive the pedal to switch between a first state away from the vehicle body and a second state adjacent to the vehicle body. The drive unit includes: A first active mounting bracket is fixed to the vehicle body; A connector having a non-coaxial first pivot axis, a second pivot axis, and a third pivot axis, wherein the first active fixing frame and the connector are rotatable relative to each other about the first pivot axis; A second active fixing bracket, fixed to the pedal, and rotatable relative to the connecting member about the second pivot axis; and A telescopic rod, with its two ends pivotally fixed to the pedal and the connecting member, respectively, wherein the telescopic rod and the connecting member are rotatable relative to each other about the third pivot axis. When the telescopic rod extends or retracts, it can cause the pedal to switch between a first state and a second state via the connecting rod and the second active fixing frame.

[0007] Preferably, the connector includes intersecting transverse and longitudinal portions, with the first pivot axis and the second pivot axis formed on both sides of the transverse portion, and the third pivot axis formed at the end of the longitudinal portion.

[0008] Preferably, the connector is T-shaped.

[0009] Preferably, the end of the telescopic rod is pivotally connected to the connector by a universal screw.

[0010] Preferably, the rotary drive pedal mechanism further includes a driven unit, the driven unit comprising: The first driven fixing bracket is fixed to the vehicle body; A second driven fixing bracket is fixed to the pedal; and A connecting plate, the two ends of which are pivotally fixed to the first driven fixing frame and the second driven fixing frame, respectively, so that the driven unit can move with the pedal. The driving unit and the driven unit are arranged at different positions along the length of the pedal.

[0011] Preferably, the drive unit is located at the middle position along the length of the pedal.

[0012] Preferably, the rotary drive pedal mechanism includes a plurality of driven units, and the driven units are arranged at least at both ends of the pedal in the length direction.

[0013] Preferably, the telescopic rod is an electrically operated telescopic rod.

[0014] Preferably, in the direction of the third pivot axis, at least the end portion of the longitudinal portion of the connector is tilted upward or downward, so that the telescopic rod is fitted below or above the connector.

[0015] Preferably, one end of the telescopic rod is pivotally fixed to the pedal via a third active fixing frame.

[0016] Based on common knowledge in the field, the above-mentioned preferred embodiments can be combined arbitrarily to obtain various preferred examples of this disclosure.

[0017] Compared to existing electric pedals, the rotary-driven pedal mechanism designed in this application has at least the following advantages: (1) Without changing the original pedal installation structure and pedal appearance, only the drive unit and driven unit are added to change the original pedal from a fixed type to an electric pedal, without encroaching on the original vehicle's Z-direction space and without affecting the original vehicle's passability. 2. The rotary drive pedal mechanism of this application has a simple and reliable drive unit structure and stable operation. Attached Figure Description

Detailed Implementation

[0020] The present disclosure will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments based on the present disclosure; those skilled in the art will conceive of other ways to implement the present disclosure based on these preferred embodiments, and such other ways also fall within the scope of the present disclosure. In the following detailed description, directional terms such as “up,” “down,” “inner,” “outer,” “longitudinal,” and “transverse” are used with reference to the directions described in the accompanying drawings. Components of embodiments of the present disclosure may be placed in various different orientations; the directional terms are for illustrative purposes and not restrictive.

[0021] In this disclosure, the rotary-driven pedal mechanism 1 is applicable to various types of vehicles, such as family SUVs and sedans, and also to other types of vehicles, such as off-road vehicles. Figure 1-2As shown, the rotary drive pedal mechanism 1 of this disclosure includes a pedal 100 and a drive unit 200, etc. The pedal 100 can be a conventional form in the prior art, and will not be described in detail here.

[0022] See Figure 4-5 and combined Figure 1-2 The drive unit 200 of the rotary drive pedal mechanism 1 is connected to the vehicle body and the pedal 100, and is configured to drive the pedal 100 to switch between a first state away from the vehicle body and a second state adjacent to the vehicle body. The drive unit 200 includes a first active fixing frame 210, a connector 220, a second active fixing frame 230, and a telescopic rod 240, etc. The first active fixing frame 210 is fixed to the vehicle body (not shown). As shown, one end of the first active fixing frame 210 (the end connected to the vehicle body) has two fixing through holes 211 (there may be more or fewer fixing through holes 211) for fasteners such as bolts to pass through for fastening. Generally, one of the two side-by-side fixing through holes 211 is a fixing through hole 211 with an elongated hole interface (see the left through hole at the upper position of the first active fixing frame 210 in 4), which facilitates adjustment of the positioning direction of the first active fixing frame 210 during installation. The other end of the first active fixing frame 210 has an open-type lifting lug 212. An opening is formed between the two lug plates 213 of the open-type lug 212, into which one end of the connector 220 (described in detail below) is inserted. Based on the above description, the surface structure of the first active mounting bracket 210 can be modified accordingly according to the requirements of different vehicle structures.

[0023] See Figure 6 and combined Figure 4-5 The connecting member 220 of the drive unit 200 has a non-coaxial first pivot axis A, a second pivot axis B, and a third pivot axis C. The first active fixing frame 210 and the connecting member 220 can rotate relative to each other about the first pivot axis A. It can be understood that, in the combined state, the axis defined by the two through holes of the pair of lug plates 213 of the first active fixing frame 210 is actually the first pivot axis A.

[0024] Connector 220 can be in the form of Figure 6 As shown in Figure 2, it includes a transverse portion 221 and a longitudinal portion 222 that intersect each other. The first pivot axis A and the second pivot axis B are respectively formed at the two transverse ends of the transverse portion 221. The third pivot axis C is formed at the end of the longitudinal portion 222. The connector 220 is generally T-shaped.

[0025] It is understandable that the T-shaped connector 220 does not mean that the overall shape of the connector 220 is exactly the same as "T". Figure 6The form shown, as well as other forms with intersecting transverse portions 221 and longitudinal portions 222, and where the longitudinal portion 222 does not cross the transverse portion 221, can all be understood as the "T" shape that this disclosure intends to protect.

[0026] As a preferred embodiment, the first pivot axis A, the second pivot axis B, and the third pivot axis C formed on the connector 220 can be defined as being parallel to each other.

[0027] Back to Figure 4-5 and combined Figure 1-2 The second active mounting bracket 230 of the drive unit 200 is fixed to the pedal 100 and is rotatable relative to the connector 220 about the second pivot axis B. Similar to one end of the first active mounting bracket 210, an open-type lug 212 is formed. An opening is formed between the two lug plates 213 of the open-type lug 212 for inserting one end of the connector 220.

[0028] In the assembled state, the two ends of the transverse portion 221 of the connector 220 are respectively inserted into the open-type lifting lugs 212 of the first active fixing frame 210 and the second active fixing frame 230, and then positioned by the fixing pin and bearing.

[0029] The telescopic rod 240 of the drive unit 200 is pivotally fixed at both ends to the pedal 100 and the connector 220, respectively. The telescopic rod 240 and the connector 220 can rotate relative to each other about the third pivot axis C. The telescopic rod 240 is pivotally fixed to the pedal 100 through the third active fixing frame 250.

[0030] Preferably, in the direction of the third pivot axis C, at least the end portion of the longitudinal portion 222 of the connector 220 is tilted upward or downward, so that the telescopic rod 240 can be fitted below or above the connector 220. This will reduce the overall space occupied by the drive unit 200.

[0031] When the telescopic rod 240 extends or retracts, it can cause the pedal 100 to switch between a first state and a second state via the connecting rod and the second active fixing frame 230. Figure 4 For reference, when the telescopic rod 240 extends (corresponding to the direction of arrow A), the connecting piece 220 rotates clockwise around the first pivot axis A, driving the second active fixing frame 230 to rotate clockwise (corresponding to rotation towards the vehicle body), and the pedal 100 retracts (i.e., enters the second state); conversely, when the telescopic rod 240 shortens (corresponding to the opposite direction of arrow A), the pedal 100 moves away from the vehicle body (i.e., enters the first state). Thus, it can be seen that, with the help of the simple drive unit 200 described above, the purpose of rotating the pedal 100 can be achieved without occupying the original vehicle's Z-axis space and without affecting the original vehicle's passability.

[0032] As a preferred option, the end of the telescopic rod 240 is pivotally connected to the connector 220 by a universal screw 223 to reduce rigid wear.

[0033] In addition, see Figure 7 and combined Figure 2 , 3 The rotary-driven pedal mechanism 1 may also include a driven unit 300. The driven unit 300 includes a first driven fixing frame 310, a second driven fixing frame 320, and a connecting plate 330, etc. The first driven fixing frame 310 is fixed to the vehicle body. Similar to the first active fixing frame 210, the first driven fixing frame 310 has an open-type lug for the connecting plate 330 (described below) to be inserted into the opening defined by a pair of lug plates.

[0034] The second driven fixing bracket 320 of the driven unit 300 is fixed to the pedal 100.

[0035] The two ends of the connecting plate 330 of the driven unit 300 are pivotally fixed on the first driven fixing frame 310 and the second driven fixing frame 320 respectively, so that the driven unit 300 can follow the pedal 100.

[0036] Optionally, the drive unit 200 and the driven unit 300 are arranged at different positions along the length of the pedal 100. The drive unit 200 is located at the middle position along the length of the pedal 100. (See attached diagram) Figure 1 , 2 Understandably, the term "middle position" here does not indicate the exact center, but rather a position between the beginning and end of the vehicle. Generally, the drive unit 200 can be positioned directly below or near the B-pillar of the vehicle.

[0037] Generally, the rotary drive pedal mechanism 1 may be provided with multiple driven units 300. Among them, the driven units 300 are arranged at least at both ends of the pedal 100 in the length direction. Without departing from the above-disclosed inventive concept, the structure of each driven unit 300 can be adjusted according to the difference in its docking position with the vehicle body, such as the size and structure of the first driven fixing frame 310.

[0038] As an alternative, the telescopic pole 240 can be configured as an electrically operated telescopic pole 240.

[0039] The scope of protection of this disclosure is defined only by the claims. Thanks to the teachings of this disclosure, those skilled in the art will readily recognize that alternative structures to the structures disclosed herein can be used as feasible alternative implementations, and that the implementations disclosed herein can be combined to produce new implementations, which also fall within the scope of the appended claims.
