Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In one aspect, an embodiment of the present invention provides a pedal mounting bracket, and fig. 1 is a schematic view of a pedal mounting bracket structure provided in an embodiment of the present invention.
In order to ensure the stability of the pedal in the using process, the brake pedal and the accelerator pedal are generally required to be installed on the front baffle plate through the pedal installation support, namely, the pedal installation support is fixed on the front baffle plate, and then the pedal base is installed on the pedal installation support, so that the pedal is installed on the front baffle plate. As shown in fig. 1, the pedal mounting bracket of the embodiment of the present invention includes a pedal mounting portion 11 and a bracket fixing portion 12. The pedal mounting portion 11 is used for mounting a pedal base, and the bracket fixing portion 12 is used for fixing the pedal mounting bracket 1 to the front fender 2.
Among them, the bracket fixing part 12 may include a first ear plate 121, a second ear plate 122, a third ear plate 123 and a fourth ear plate 124. The first ear plate 121 and the third ear plate 123 are oppositely disposed, and the second ear plate 122 and the fourth ear plate 124 are oppositely disposed.
In the correlation technique, the pedal installing support only relies on the fixed part of both sides to be connected with preceding baffle, and the intensity that so probably leads to the junction is not enough, and then makes the vibration of preceding baffle very easily transmit accelerator pedal, leads to accelerator pedal's vibration too big, makes driver's foot tingle, influences driver's driving experience, influences driving safety even.
Compared with the related art, the first ear plate 121 and the third ear plate 123 are additionally arranged on the bracket mounting part 12 in the embodiment of the present application to increase the contact area between the pedal mounting bracket 1 and the front baffle 2, so that the pedal mounting bracket 1 can be more firmly fixed on the front baffle 2.
In addition, in the embodiment of the present application, the first ear plate 121 and the second ear plate 122 are both provided with a first welding point M. The first weld points M are two layers of weld points so that the pedal mounting bracket 1 and the front baffle 2 can be connected. The third ear plate 123 and the fourth ear plate 124 are both provided with a second welding point N. The second welding point N is a triple layer welding point, so that the pedal mounting bracket 1, the front baffle 2 and the front baffle cross member 3 can be connected.
The front fender cross member 3 is a first cross member behind the front bumper, and is generally formed by stamping a low alloy steel plate, and the cross-sectional shape thereof is generally a groove shape, or may be a Z-shape or a box shape. The automobile body has certain strength and rigidity, and can play a role in protecting the automobile body during collision.
The pedal mounting bracket 1 is connected with the front baffle 2 and the front baffle beam 3 by utilizing the second welding point N on the third lug plate 123 and the fourth lug plate 124, and the connecting part of the front baffle beam 3 is added, so that the mechanical property advantage of the front baffle beam 3 is exerted, the connecting strength of the pedal mounting bracket 1 is enhanced, and the shaking condition of the pedal can be improved.
The number of the first welding points M and the second welding points N is at least one. The number and distribution of the solder joints are mainly determined by the performance requirements and the size of the ear plate where each solder joint is located. Due to the performance requirements, the size of the pedal mounting bracket 1 needs to be adjusted sometimes, for example, when the whole pedal base to be fixed is large, in order to ensure the connection stability, the size of the whole pedal mounting bracket 1 needs to be increased correspondingly, that is, the size of each ear plate is also increased correspondingly. At this time, it is necessary to increase the number of welding points appropriately to firmly fix the pedal attachment bracket 1 to the front fender 2.
It should be noted that when the first welding point M and the second welding point N are provided as one welding point, it is preferable to provide the welding point at the midpoint of each ear plate to ensure the stability of the connection. When a plurality of solder points are provided, it is preferable that the solder points are arranged symmetrically.
Details of the size and shape of the first ear plate 121, the second ear plate 122, the third ear plate 123, and the fourth ear plate 124 will be further described below.
In terms of the size of the above-mentioned several lugs, each lug is dimensioned to ensure at least a sufficient contact area between the pedal mounting bracket 1 and the front baffle 2. But the size is not required to be set to be too large, and the excessive size can cause waste of materials; secondly, the front baffle 2 is provided with more components and limited installation space. If the pedal mounting bracket 1 is made excessively large, it takes up too much space and interferes with the mounting of other components.
It should be noted, however, that the first and third ear panels 121 and 123 have certain desired longitudinal dimensions. The above-mentioned longitudinal dimension is at least to ensure that the first ear plate 121 and the third ear plate 123 can be overlapped with the front baffle 2 and the front baffle cross beam 3 when the pedal mounting bracket 1 is fixed on the front baffle 2. The three parts can be connected by welding to increase the connection strength of the pedal mounting bracket 1. The length of the overlap can be set accordingly as the case may be.
The shape of the ear plates is not limited to a few, and may be rectangular, for example.
When the ear plate is rectangular in shape, the edges of the rectangle are sharp, so that an operator may be scratched during installation, and the edges are preferably rounded. The size of the chamfer can be adjusted according to specific conditions.
The shape of the oppositely disposed second ear plate 122 and fourth ear plate 124 may be the same or different. Similarly, the first ear plate 121 and the third ear plate 123 may be identical in shape or different in shape. And the first ear plate 121 and the third ear plate 123 are designed according to the position or size of the front fender cross member 3, depending on whether the pedal mounting bracket 1 can be lapped on the front fender 2 and the front fender cross member 3. Therefore, the first ear plate 121 and the third ear plate 123 may not be provided symmetrically. That is, the stent fixing part 12 may have a symmetrical structure or an asymmetrical structure.
In order to avoid the occurrence of stress concentration, it is preferable that the boundaries between the ear plates are rounded. Thus, fatigue cracks are not easy to generate at the junction of the lug plates in the using process, so that the service life of the pedal mounting bracket 1 can be prolonged.
Further, as shown in fig. 2, the pedal mounting portion 11 may include a first inclined plate 111, a first side plate 112, a second inclined plate 113, and a second side plate 114.
The first inclined plate 111 and the second inclined plate 113 are connected to form a gable roof structure. And the first side plate 112 and the second side plate 114 are respectively disposed at both sides of the delta roof type structure, and the first side plate 112 and the second side plate 114 are connected to sides of the first sloping plate 111 and the second sloping plate 113.
And the lower edge of the first inclined plate 111 is connected with the first lug plate 121; the lower edge of the first side plate 112 is connected with the fourth ear plate 124; the lower edge of the second sloping plate 113 is connected with the third ear plate 123; the lower edge of the second side plate 114 is connected with the second ear plate 122;
the first inclined plate 111 is inclined with respect to the plane of the bracket mounting portion 12, and an included angle therebetween is an acute angle. Its main function is to provide a mounting surface for the pedal base, that is, the upper surface of the first sloping plate 111 is used for mounting the pedal base. Second, it also serves to connect the first ear plate 121.
The inclination angle of the first inclined plate 111 depends on the setting angle of the pedal base, and the angle setting of the pedal base mainly takes the habituation and comfort of the driver stepping on the feet during driving into consideration. According to the embodiment of the invention, a large number of man-machine checking experiments show that when the included angle between the first inclined plate 111 and the plane where the bracket fixing part 12 is located is 45-60 degrees, a driver is less strenuous in treading the pedal. By setting the inclination angle of the first swash plate 111 in this way, the driving experience of the driver can be improved.
The second swash plate 113 mainly functions to support the first swash plate 111. It forms a gable roof type structure with the first inclined plate 111, so that the overall structure of the step mounting bracket 1 can be more stable. Second, it also serves to connect the third ear plate 123.
The inclination angle of the second inclined plate 113 is set according to the inclination angle and size of the first inclined plate 111, since it is required to be connected with the first inclined plate 111 to form a roof-type structure.
The first side plate 112 and the second side plate 114 are located on both sides of the gable top structure to support the same. In addition, the first side plate 112 and the second side plate 114 are connected to a fourth ear plate 124 and a second ear plate 122, respectively.
For the first side plate 112 and the second side plate 114, the size of the included angle between the first side plate and the second side plate and the plane of the bracket fixing part 12 has a certain influence on the overall strength of the pedal mounting bracket 1.
When the first side plate 112 and the second side plate 114 are disposed obliquely inward (they are close to each other), the entire strength of the pedal mounting bracket 1 is not high and can withstand only a limited pressure. Therefore, when the pedal receives a large stepping force, the pedal mounting bracket 1 may be crushed.
When the first side plate 112 and the second side plate 114 are perpendicular to the bracket fixing portion 12, the first side plate 112 and the second side plate 114 have the best supporting ability. However, it is difficult to reach 90 ° by one hundred from the viewpoint of molding process, and therefore, the included angle may be set to be between 80 ° and 100 °.
The included angles between the first side plate 112 and the second side plate 114 and the plane of the bracket fixing portion 12 are preferably the same, so that the stability of the pedal mounting bracket 1 is better.
In the embodiment of the present invention, the lower edges of the four components of the pedal mounting portion 11 are respectively connected to the four ear plates of the bracket fixing portion 12. These connecting portions are preferably designed as rounded corners to avoid stress concentrations that would affect the service life of the pedal mounting bracket 1.
A step base is attached to an upper surface of the first swash plate 111, and when a driver steps on a step to apply a predetermined pressure to the step base, the pressure is mainly borne by a roof-shaped structure formed by the first swash plate 111 and the second swash plate 113. When the driver steps on the pedal, the force applied to the second swash plate 113 supporting the first swash plate 111 is the greatest (in the direction opposite to the direction in which the second swash plate 113 is inclined) due to the force transmission, and thus the joint between the second swash plate 113 and the third lug plate 123 is weak.
In view of this, in the embodiment of the present application, the reinforcing rib 13 is disposed between the second sloping plate 113 and the third ear plate 123 to reinforce the strength of the joint between the second sloping plate 113 and the third ear plate 123, so as to bear a larger treading pressure.
As for the specific shape and structure of the reinforcing rib 13, it may be a triangular convex rib, and may also be a circular or elliptical concave rib, which is not limited herein.
Also, similar ribs may be provided between the first side plate 112 and the fourth ear plate 124. Similarly, a stiffener may be disposed between the second side panel 114 and the second ear panel 122. That is, the reinforcing beads can be flexibly arranged according to the requirement for strength.
During the running process of the vehicle, a driver can press a valve pedal to accelerate. Since the pedal is connected to the front fender 2 through the pedal mounting bracket 1, when the driver presses the door pedal downward, the pedal may collide with the first swash plate 111 of the pedal mounting bracket 1 located below. In order to avoid this, in the embodiment of the present invention, an avoidance structure 116 is further provided on the first sloping plate. The avoiding structure 116 is disposed at a connection between the first sloping plate 111 and the first ear plate 121. The shape of the escape structure 116 is designed according to the installation angle of the pedal and the tread locus of the driver's foot.
For example, as shown in fig. 2, the avoiding structure 116 is formed by extending the lower portion of the first sloping plate 111 toward the first ear plate 121. Here, the lower edge of the first inclined plate 111 is in a shape of a notch, and such a shape can ensure that the first inclined plate 111 has a sufficient contact area with the pedal base, and can avoid the motion track of the feet to avoid the collision.
Based on the above structure of the pedal mounting bracket 1, the pedal mounting portion 11 and the bracket fixing portion 12 of the pedal mounting bracket 1 can be integrally formed, and therefore, the forming process of the pedal mounting bracket 1 is simple.
The embodiment of the invention has no limitation on the material of the pedal mounting bracket 1, and the pedal mounting bracket can be a metal piece or a plastic piece.
If the pedal attachment bracket 1 is a metal member, the pedal attachment portion 11 and the bracket fixing portion 12 can be integrally formed by a press process.
When the pedal mounting bracket 1 is a metal member, the thickness of each portion is kept uniform. Typically, the thickness is 1.2mm to 1.5mm, and the maximum thickness will not exceed 2mm, which would result in an excessive overall weight of the pedal mounting bracket 1.
If the pedal mounting bracket 1 is a plastic member, the pedal mounting portion 11 and the bracket fixing portion 12 may be integrally formed by an injection molding process.
The pedal attachment bracket 1 may be made of carbon fiber. Specifically, layering carbon fiber cloth on a mold, then carrying out curing treatment of pressurizing and heating to obtain a preform, finally placing the preform into a mold cavity, and shaping the preform in a resin injection manner to obtain the carbon fiber pedal mounting bracket. It should be noted that the number of carbon fiber cloth layers should be set appropriately so as to ensure the strength of the pedal mounting bracket 1.
In one possible implementation, the first sloping plate 111 is provided with a first through hole 115, and a projection nut (not shown) is provided on the side of the first through hole 115 facing the front baffle 2, that is, the projection nut is welded to the inside of the pedal mounting bracket 1. Correspondingly, the pedal base is provided with a threaded hole which is matched with the first through hole 115. When assembling like this, only need to align the screw hole on the footboard base with the first through-hole 115 of footboard installing support 1 to connect with the bolt, can realize the rapid Assembly of footboard base and footboard installing support 1 through screwing up the bolt.
In a possible implementation manner, the first inclined plate 111 is further provided with a second through hole 117. The second through hole 117 is a jig positioning hole. When welding is performed, a welding jig may be inserted into the second through hole 117 to facilitate the welding operation.
The following describes the installation of the pedal mounting bracket provided in the embodiment of the present application with reference to fig. 4 and 5.
Fig. 4 shows a state in which the accelerator pedal base 4 is fixed to the vehicle body dash 2 by the pedal mounting bracket 1 according to the embodiment of the present invention. Fig. 5 shows the pedal mounting bracket 1 assembled with the integrated pedal base 6. It should be noted that, in practical applications, the brake pedal 7 and the accelerator pedal (not shown in fig. 5) are simultaneously mounted on the integrated pedal base 6, but only the brake pedal 7 (left side) is shown in fig. 5, and the three bolts on the right side are used for mounting the accelerator pedal assembly.
As can be seen from the figures 4 and 5, no matter the split accelerator pedal base 4 or the integrated pedal base 6, the assembly of the pedal mounting bracket 1 of the embodiment of the application can be realized only by arranging corresponding threaded holes on the base body and connecting the base body with bolts. It can be seen that the pedal mounting bracket 1 is highly versatile. Different pedal mounting brackets do not need to be matched with pedal bases in different forms, so that the design cost is saved. And pedal base cooperation to different forms uses the footboard installing support 1 of the same structure, and the easy mistake proofing of installation also is convenient for maintain.
In addition, as can be seen from fig. 4, when the pedal mounting bracket 1 provided by the embodiment of the invention is mounted on the front baffle 2 of the vehicle body, the whole body is similar to an open box, and four 'ears' for sealing are all opened outwards and are reversely buckled on the front baffle. Due to the structural design, the pedal mounting bracket 1 and the front baffle 2 have larger contact area, and the connection strength of the pedal mounting bracket 1 is higher.
In addition, the pedal mounting bracket 1 is small in size and small in occupied space, so that the mounting space of the front baffle can be saved, and other components can be conveniently mounted.
The pedal mounting bracket provided by the embodiment of the invention comprises a pedal mounting part and a bracket fixing part, wherein the bracket mounting part comprises a first lug plate, a second lug plate, a third lug plate and a fourth lug plate. The pedal mounting bracket is additionally provided with the first lug plate and the second lug plate which are used for fixing the pedal mounting bracket, so that the pedal mounting bracket can be more firmly fixed on the front baffle. And first otic placode and second otic placode are connected with preceding baffle and preceding baffle crossbeam, have increased adapting unit to the joint strength of footboard installing support has been improved. Install the footboard on the baffle before the automobile body through this footboard installing support, can show the vibration condition that improves accelerator pedal, and then promote driver's comfort. In addition, this footboard installing support both can be used to above-mentioned integral type footboard base, also is applicable to above-mentioned split footboard base, and the commonality is stronger.
In another aspect, the present invention also provides a vehicle including the pedal mounting bracket of any of the above embodiments. The pedal is fixed on the front baffle of the vehicle body through the pedal mounting bracket, so that the shaking condition of the pedal can be effectively improved.
The shock absorbing capability of the pedal mounting bracket provided by the embodiment of the present invention will be further described with reference to fig. 6, 7 and 8.
In order to verify the shock absorption performance of the pedal mounting bracket provided by the embodiment of the invention, the embodiment of the invention utilizes finite element simulation software to analyze the vibration condition of the pedal.
It should be noted that, if the brake pedal base and the accelerator pedal base are designed as an integral body, the whole body is taken as a research object; if the brake pedal base and the accelerator pedal base are designed separately, the accelerator pedal is taken as a research object.
Fig. 6, 7 and 8 are schematic diagrams of the vibration response of the pedal in the X direction, the Y direction and the Z direction respectively before and after optimization.
In the three diagrams, the abscissa represents frequency and the ordinate represents vibration amplitude. The BASE straight line represents the vibration condition before optimization, and the CASE dotted line represents the vibration condition after optimization.
It should be noted that the frequency is related to the rotation speed of the engine of the automobile, and the rotation speed is about 30 times of the frequency.
As can be seen from FIG. 5, when the frequency is in the range of 130Hz to 140Hz, the solid line and the dotted line substantially coincide; when the frequency is in the range of 140Hz to 150Hz, the solid line is located all the way below the dashed line. This indicates that the vibration conditions in the X direction after pedal optimization are substantially the same as before optimization, and are not improved, at frequencies between 130Hz and 140 Hz; when the frequency is 130 Hz-140 Hz, the vibration condition of the pedal in the X direction is improved to a certain extent.
As can be seen from fig. 6, when the frequency is in the range of 130Hz to 150Hz, the dotted line is always located below the solid line, and the distance between the two lines is large. This shows that the vibration of the pedal in the Y direction is improved significantly at frequencies of 130Hz to 150 Hz.
As can be seen from FIG. 7, when the frequency is in the range of 130Hz to 140Hz, the solid line and the dotted line substantially coincide; when the frequency is in the range of 140Hz to 150Hz, the dotted line is located all the way below the solid line. This shows that the vibration in the Z direction after pedal optimization is substantially the same as before optimization, with frequencies between 130Hz and 140Hz, and is not improved; when the frequency is 140 Hz-150 Hz, the vibration condition of the pedal in the Z direction is improved to a certain extent.
From the above analysis, it can be seen that the pedal is mounted on the front baffle through the pedal mounting bracket, and the vibration of the pedal in the three directions of X, Y and Z is improved in the frequency range of 130Hz to 150 Hz. Among them, the improvement of the Y-direction vibration is most remarkable.
It should be explained here that the above analysis only concerns the vibration of the pedal in the X, Y and Z directions in the range of 130Hz to 150 Hz.
This is because the vehicle is accelerated, the vibration of the engine is significantly increased, and the vibration is transmitted to the pedal through the front fender, so that the feet of the driver are tingled, and the driving state of the driver is affected. Therefore, the pedal is shaken most severely during acceleration, and important attention is required. And the rotating speed of the engine during acceleration generally does not exceed 4000 revolutions, and the frequency corresponding to the rotating speed during acceleration is 130 Hz-150 Hz according to the relationship between the rotating speed and the frequency. Therefore, when the vibration condition before and after pedal optimization is analyzed, only the vibration amplitude of the frequency band needs to be considered.
And as can also be seen from the three figures, in a low frequency band (the frequency is less than 130Hz), the broken lines are basically below the solid lines, which shows that the shaking condition of the pedal is improved in the normal running process (the rotating speed is low and the frequency is low) of the vehicle by mounting the pedal through the pedal mounting bracket. The rotation speed corresponding to the high frequency range (the frequency is more than 150Hz) is not the rotation speed used by the vehicle in normal running and acceleration, so the shaking condition of the pedal in the frequency range can be ignored.
Therefore, the pedal is arranged on the front baffle plate of the vehicle body through the pedal mounting bracket of any embodiment, so that the vibration condition of the accelerator pedal can be improved, and the comfort of a driver is improved.
