Description

PEDAL STRUCTURE SUITABLE TO DRIVER'S SPHINE AND LEG AND ASSEMBLY THEREOF

The present invention relates to a pedal structure and its pedal assembly capable of changing the position or angle of the pedal to suit a body size that varies from driver to driver.

The seat and pedals of the car have a very important influence on the driver's posture associated with back pain. So far, research and development of the pedals are inadequate compared to the automobile seats in which much ergonomic development has been made.

In the low-body sedan, as well as in the high-body SUV, the driver's knee angle is adjusted according to the pedal position change, so that the erector spinae, the rectus femoris, the tibialis anterior, and the soleus As much as possible, the burden on gastrocnemius and biceps femoris can be reduced.

Since the car is used for a long time as a means of transportation for commuting and leisure, the driver's comfort due to the driver's tax is important. The static posture of driving a car is related to the cause of low back pain. The muscle fatigue from the long driving period is a deterrent to comfort, and the low muscle activity level means that the driver is comfortable. Car seats are a very important factor that impairs comfort. A study was conducted to find the optimal joint angle by analyzing each joint angle for a comfortable driving posture.A study was conducted to find a comfortable posture in sedan and SUV vehicles by dividing 16 joint angles and suggesting the recommended angle for each joint. There was also.

The pedal's mechanical position is also important for comfort. Correct contact of the support surface with the feet in a sitting position also affects even weight distribution, and as the normal somatosensory input can maintain a stable posture, the feet are in a symmetric posture and upright position. It is necessary to balance the trunk muscles.

This symmetrical attitude keeps the tension of lumbar muscles together with the stability of the support surface and achieves harmonious activity.

Maintaining balanced muscle strength and endurance is very important because trunk muscles are essential for maintaining various postures in daily life. Like this, driving is not simply sitting and manipulating the steering wheel, but it consists of balanced and efficient movements of various bodies. Therefore, driver's comfort and comfort are essential factors, and these parts are combined to allow safe and fast movement.

In addition, there may be a variety of body types, from small-sized women to large men, whose only adjustment is the position of the seat and the handle. Depending on the position of the seat and the handle, there may be a proper position and angle of the pedal, but the reality is that the research on the pedal is not done enough.

Accordingly, research on a pedal structure for maximizing endurance of trunk muscles by minimizing muscle activity of the driver is required.

It is an object of the present invention to solve the above and other problems. Another object is to provide a pedal structure and an assembly therefor that can change the pedal position and angle to fit the body of the driver.

Therefore, driver's comfort and comfort are essential factors, and these parts are combined to allow safe and fast movement.

 It is an object of the present invention to create an adjustable seat and pedal that can minimize the low back pain burden of hospital patients using private cars. Patients who come to the hospital due to back pain and disc problems are avoiding public transportation and moving mainly to their own cars, because these cars also act as painful factors. In terms of comfort and comfort, it creates an adjustable seat and pedal to minimize the driver's back pain.

Comfort and comfort are not only the seat adjustment but also the driver's pedal and the lower back muscle activity in the driver's muscles, the difference between the activity of the development began. In this study, we tried to implement pedal position and angle with low activity of erectile muscles and lower extremity muscles.

In addition, the seat angle was applied to 105 °, which was found to lower comfort of the upper and lower body muscles, and the knee angle was 110 ° and the ankle angle was 90 °.

2 is a diagram illustrating a conceptual diagram of a pedal system 100 applied to a vehicle interior according to an embodiment of the present invention.

In the illustrated figure, not all of the pedal system 100 is shown, and some of the pedal system 100 may be integrally formed with other components of the vehicle.

Referring to FIG. 2, a driver 201 is shown sitting in a seat 202 of a vehicle and driving. In addition, the driver 201 of the vehicle operates the vehicle by using the pedal assembly 200 of the pedal system 200 according to the exemplary embodiment of the present invention. For example, the pedal assembly 200 is used as an accelerator pedal.

3 and 4 are front and rear perspective views of the pedal assembly 200 according to an embodiment of the present invention.

The pedal assembly 200 includes a case (for example, a frame, a housing, a cover, etc.) forming an appearance.

These cases may be formed by injecting a synthetic resin, or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti) and the like.

The pedal assembly 200 may be configured such that one case provides the internal space, unlike the above example in which a plurality of cases provide an internal space for accommodating various electronic components. In this case, the unibody pedal system 100 may be implemented in which the synthetic resin or metal extends from the side to the rear.

5 and 6 are exploded views of the pedal assembly 200 according to an embodiment of the present invention. It demonstrates with reference to FIGS. 3-6.

Vehicle pedal assembly 200 according to an embodiment of the present invention, the sliding portion 302 which is slidably movable so as to change the position relative to the driver seat 202; A position adjusting unit capable of adjusting the position of the sliding unit 302; And a pedal 303 pivotally coupled with the sliding part 302.

The position adjusting unit includes a power unit 154 providing power to the sliding unit; And a rail 301 through which the sliding part may slide. The power unit 154 may be controlled by the controller 180.

The controller 180 may control the position adjusting unit based on a user signal input through the user input unit. By controlling the position adjusting unit, the position of the sliding unit 302 described above may be changed to a position desired by the user.

Although not shown in the drawings, the position adjusting unit may further include a locking device to be fixed after the sliding unit 302 is slid. This is because it is possible to drive stably by activating the locking device when driving the vehicle.

The controller 180 may sense an angle at which the pedal (stool) is rotated, and control the vehicle based on the sensing result. In this case, the control unit 180 itself is not sensed, but the sensing unit 153 senses this, and the control unit 180 may receive and utilize it.

In particular, in the case of vehicle control such as Excel or brake, the strength varies depending on how much the pedal is pressed. Acceleration of the accelerator pedal is weak, and vehicle acceleration is weak. Acceleration of the accelerator pedal may be a strong vehicle acceleration. Therefore, it will be apparent that the signal for controlling the vehicle by the controller 180 varies depending on the angle rotated from the basic angle (basic position) of the pedal.

The pedal 303 may include a body 305, a footrest 303, and a footrest support 304. The footrest 303 is pivotally coupled to the body portion 305 to control the vehicle by tilting the footrest 305 as desired by the driver. In addition, the restoring force for restoring the footrest support 304 to the initial position of the footrest 303 may be provided. This restoring force may be provided by a material having elasticity, such as a spring, as shown in the figure.

In addition, the scaffold support 304 according to an embodiment of the present invention may be provided to change the length.

As shown in the figure, the scaffold support 304 may be provided with a length adjusting bar 601 that can change the length. The length adjustment bar 601 forms a tooth 603 at one end, and the length of the entire scaffold support 304 may be changed by adjusting the position of the tooth 603.

On the other hand, it is obvious that the above-described change of the position of the tooth 603 can be made by the control of the controller 180. The scaffold support 304 may be changed in the engagement position of the tooth 603 by the power of the power unit provided inside and outside, and thus the length of the scaffold support 304 may be changed.

One end of the scaffold support 304 may be pivotally coupled to the body portion 305. The other end of the scaffold support 304 may be pivotally coupled to the rear surface of the scaffold 303.

7 is a view showing a detailed view of the footrest 303 according to an embodiment of the present invention.

And the footrest 303 may form a fixing groove 604 is formed long in a predetermined direction. In the illustrated figure, the fixing groove 604 is formed in the same direction as the longitudinal direction of the scaffold 303. In the illustrated figure, two fixing grooves 604 are formed at right and left, but the number is not limited thereto.

The scaffold support 304 may be coupled to a point on the fixed groove 604 formed long, and the basic position (basic inclination) of the scaffold 303 may be determined according to the position where the scaffold support 304 is coupled. That is, in one embodiment of the present invention is proposed to change the basic position of the footrest 303 to be provided to change the position where the other end of the footrest support 304 is coupled to the rear of the footrest 303. Such an embodiment will be described with reference to FIGS. 8 and 9.

8 and 9 illustrate a method of changing a basic position of the footrest 303 according to an embodiment of the present invention.

As described above, one end of the scaffold support 304 may be coupled to one point on the fixing groove 604 formed long, and the basic position (basic inclination) of the scaffold 303 according to the position at which the scaffold support 304 is coupled. May be determined.

Referring to FIG. 8, one end of the scaffold support 304 is fastened to a lower end portion of the fixing groove 604. The length of the scaffold support 304 is relatively long. In this state, the angle of the basic position of the footrest 303 will be formed relatively larger (ie, closer to 90 degrees) than in the case of FIG. In addition, the angular range in which the scaffold can be moved may also be larger than in FIG. 9.

9, one end of the scaffold support 304 is fastened to an upper end portion of the fixing groove 604. And, the length of the scaffold support 304 is in a relatively short state. In this state, the angle of the basic position of the footrest 303 will be formed relatively smaller than that of FIG. 8 (that is, the foothold lays down to the floor). And the angular range in which the scaffold can move can also be formed smaller than in FIG.

That is, the pedal assembly 200 according to an embodiment of the present invention increases the operating range (the range of the angle at which the foot is inclined) when the angle of the basic position is large as shown in FIG. 8, and the basic position as shown in FIG. 9. When the angle of is small, it is suggested to reduce the operating range.

Furthermore, in the present invention, it is proposed that the strength of the restoring force varies depending on the angle of the scaffold 303. As shown in FIG. 8, as the scaffold 303 gets closer to the right angle, the restoring force becomes smaller, and as the scaffold 303 gradually lie down as shown in FIG. 9, the restoring force may be increased. This restoring force will eventually increase the strength of the restoring force automatically shortened the length of the scaffold support (304). This is because the elastic force is determined by the following equation.

Where F is the restoring force (unit: N), k is the elastic modulus, and x is the length of the compressed or extended spring.

That is, when the length of the scaffold support 304 is adjusted by the length adjustment bar 601 described above, the repulsive force as short as it will be applied to the restoring force.

The reason why the restoring force is stronger as the footrest 303 is laid down, the more the angle of the footrest 303 is laid down, the greater the force to press the footrest basically because of the weight of the driver's leg itself. Therefore, the greater the resilience can help the driver to drive more comfortable.

In addition, when the restoring force is large in this manner, it will be difficult to increase the angular range of the footrest 303. Therefore, one embodiment of the present invention proposes to reduce the angular range of the footrest 303 as shown in FIG.

Furthermore, in an embodiment of the present invention, when the position of the pedal is far from the seat, it is proposed to set the basic position of the pedal so as to be close to the right angle as in FIG. The reason for this is that the closer the pedal is to the seat, the smaller the angle between the driver's thigh and calf, since the ankle must be flipped up to maintain the previous pedal angle.

This embodiment will be described with reference to FIGS. 10 and 11.

10 and 11 are diagrams illustrating pedal angle adjustment according to an embodiment of the present invention.

When the pedal is far away, as shown in Figure 10, even if the pedal angle is close to the right angle does not matter much. Because you can stretch your legs straight, you can adjust the angle of the pedal without having to bend your ankle upwards.

However, it is not easy to do so when the pedal is close to the seat as shown in FIG.

First, since the pedal is close in FIG. 11, the height of the driver's seat should be raised slightly under the premise of the same person as in FIG. 10. To raise the foot on the footrest in the raised state, the angle of the thigh and calf will eventually be smaller than in FIG. 10 so that the angle of the sole of the foot at the comfort of the driver will also be reduced to be parallel to the floor. In other words, the driver will be forced to lift the ankle to be able to put the foot on the pedal.

Too much ankle in this way can put a strain on the driver.

Therefore, the controller 180 according to the exemplary embodiment of the present invention may control the angle of the pedal to be smaller when the sliding part 302 approaches the driver's seat.

At this time, the angle of the pedal may be manually changed by the user's input, but the controller 180 may automatically calculate the distance to the seat and automatically change the optimal angle.

Although the embodiment of the pedal system 100 according to the present invention has been described above, it will be described as at least one embodiment, whereby the technical idea and its construction and operation of the present invention are not limited. The scope of the technical spirit of the present invention is not limited or limited by the drawings or the description with reference to the drawings. In addition, the concept and embodiment of the invention presented in the present invention may be used by those skilled in the art as a basis for modifying or designing to other structures for carrying out the same purpose of the present invention. The equivalent structure modified or changed by those skilled in the art to which the present invention pertains is to be bound by the technical scope of the present invention described in the claims, and the spirit or scope of the invention described in the claims. Various changes, substitutions and alterations are possible without departing from the scope of the invention.
