Description

Technical Field

[0001] The utility model relates to the technical field of vehicle electric pedals, and in particular to an electric pedal driving structure. The utility model also relates to an electric pedal provided with the electric pedal driving mechanism, and a vehicle provided with the electric pedal. Background Art

[0002] At present, some models on the market, such as SUV (Sport Utility Vehicle), have a chassis that is higher than the ground, making it difficult for drivers and passengers to get on and off the vehicle. Therefore, some SUV vehicles are equipped with side pedals to assist drivers and passengers in getting on and off the vehicle.

[0003] Existing vehicle side pedals mainly include two structures: fixed pedals and electric pedals. Fixed pedals are directly fixed to the side of the vehicle and cannot move relative to the vehicle body. Although they have a simple structure, they also affect the vehicle's passability in some occasions. Electric pedals are installed on the side of the vehicle through an electric drive structure. Driven by the electric drive structure, the pedals can be unfolded and retracted relative to the vehicle body. Not only does it have a good sense of technology and can improve the grade of the vehicle, but it can also avoid affecting the vehicle's passability.

[0004] At present, the electric drive structure of the electric pedal is generally composed of a motor and a connecting rod assembly. The connecting rod assembly usually includes an active connecting rod and a driven connecting rod, and together with the fixed bracket on the vehicle body and the pedal chassis, it forms a four-bar linkage. Although this electric drive structure in the form of a four-bar linkage can realize the drive to expand and retract the pedal, it occupies a large space in the Y direction of the vehicle due to its single cantilever structure (generally more than 200mm). At the same time, the movement form of the pedal can only be a single expansion and retraction of the vehicle in the Y direction, which limits the application effect of the electric pedal. Utility Model Content

[0005] In view of this, the utility model aims to propose an electric pedal driving mechanism, so as to provide a new electric pedal driving structure and improve the application effect of the electric pedal.

[0006] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0007] An electric pedal driving mechanism comprises a driving assembly and a connecting rod assembly connected to the driving assembly;

[0008] The connecting rod assembly includes a first connecting rod, a second connecting rod, a third connecting rod and a transmission connecting rod;

[0009] The first connecting rod is hinged between the vehicle body fixing bracket and the pedal base, one end of the second connecting rod is hinged to the first connecting rod, one end of the third connecting rod is hinged to the pedal base, and the other ends of the second connecting rod and the third connecting rod are hinged to one end of the transmission connecting rod, and the other end of the transmission connecting rod is connected to the driving assembly.

[0010] Furthermore, under the rotation drive of the driving assembly, the transmission connecting rod can drive the second connecting rod and the third connecting rod to rotate and move relative to the vehicle body fixing bracket, the second connecting rod can drive the first connecting rod to rotate, and the first connecting rod and the third connecting rod can jointly drive the pedal base to rotate and move relative to the vehicle body fixing bracket.

[0011] Furthermore, the first connecting rod, the second connecting rod, the third connecting rod and the pedal chassis form a four-bar linkage;

[0016] The transmission connecting rod is located between the second connecting rod and the third connecting rod.

[0017] Further, the first connecting rod has two connecting rod arms arranged opposite to each other;

[0018] One end of the second connecting rod hinged to the first connecting rod, and a portion of the pedal chassis hinged to the first connecting rod, are both located between the two connecting rod arms.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] The electric pedal driving mechanism described in the utility model can form a six-link mechanism together with the vehicle body fixing bracket and the pedal base frame by making the connecting rod assembly include a first connecting rod, a second connecting rod, a third connecting rod and a transmission connecting rod. Therefore, it can not only provide a new type of electric pedal driving structure, but also enable the pedal to move and rotate relative to the vehicle body fixing bracket under the transmission of the six-link mechanism, which helps to reduce the Y-direction layout space of the electric pedal, thereby improving the application effect of the electric pedal.

[0022] In addition, under the rotation drive of the driving assembly, the transmission connecting rod drives the second connecting rod and the third connecting rod to rotate and stretch, the second connecting rod drives the first connecting rod to rotate, and the first connecting rod and the third connecting rod jointly drive the pedal chassis to rotate and stretch, which can specifically realize the stretching and rotation drive of the pedal, so as to achieve the purpose of reducing space occupation on the basis of meeting the use requirements of the electric pedal.

[0023] Secondly, the hinge points of the transmission link and the second link, and the hinge points of the transmission link and the third link are coaxially arranged, which can simplify the hinge structure of the transmission link, the second link and the third link.

The transmission link is located between the second link and the third link, which can improve the stability of the transmission of the transmission link and the stability of the operation of the driving mechanism.

[0024] Furthermore, the first connecting rod has connecting rod arms arranged relatively to each other, and the second connecting rod and the part where the pedal chassis is hinged to the first connecting rod are located between the two connecting rod arms, which can increase the reliability of the hinge between the second connecting rod and the pedal chassis and the first connecting rod, and can also make the relative movement between the first connecting rod, the second connecting rod and the pedal chassis more stable. The driving assembly is composed of a driving motor and a reducer, has a simple structure, low cost, and can achieve reliable driving of the pedal movement.

[0028] An anti-slip structure is arranged on the tread surface of the pedal.

[0029] The electric pedal described in the utility model, by adopting the above-mentioned electric pedal driving mechanism, helps to reduce the Y-direction arrangement space of the electric pedal, which can be beneficial to the arrangement of the electric pedal on the vehicle, thereby improving the application effect of the electric pedal.

[0030] Moreover, by providing a pre-hanging structure that bites together between the pedal and the pedal chassis, the connection assembly can be coordinated to facilitate the connection between the pedal and the pedal chassis, and the stability of the connection between the pedal and the pedal chassis can be improved. Providing an anti-slip structure on the tread surface of the pedal can increase the safety of the driver and passengers when using the electric pedal.

[0031] In addition, the utility model also provides a vehicle, on which the electric pedal as described above is provided.

[0055] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0056] Embodiment 1

[0057] The present embodiment relates to an electric pedal driving mechanism, which is used in an electric pedal on a vehicle and is specifically used to drive the pedal in the electric pedal to move so as to unfold or retract relative to the vehicle body. At the same time, the electric pedal driving mechanism of the present embodiment can provide a new type of electric pedal driving structure and can improve the application effect of the electric pedal.

[0058] In terms of overall structure, combined Figures 1 to 3 As shown in , the electric pedal driving mechanism of this embodiment includes a driving assembly 100 and a connecting rod assembly 200 connected to the driving assembly 100 .

[0059] The connecting rod assembly 200 includes a first connecting rod 8 , a second connecting rod 7 , a third connecting rod 5 and a transmission connecting rod 6 .

[0060] The first connecting rod 8 is hinged between the vehicle body fixing bracket 1 and the pedal base frame 3, one end of the second connecting rod 7 is hinged to the first connecting rod 8, one end of the third connecting rod 5 is hinged to the pedal base frame 3, and the other ends of the second connecting rod 7 and the third connecting rod 5 are hinged to one end of the transmission connecting rod 6, and the other end of the transmission connecting rod 6 is connected to the driving assembly 100.

[0061] At this time, as set above, by making the connecting rod assembly 200 include a first connecting rod 8, a second connecting rod 7, a third connecting rod 5 and a transmission connecting rod 6, it can form a six-link mechanism together with the vehicle body fixing bracket 1 and the pedal base frame 3. In this way, this embodiment is equivalent to the four-link mechanism commonly used in the prior art, and can provide a new type of six-link electric pedal drive structure. At the same time, it can also be driven by the six-link mechanism, so that the pedal 4 can be stretched and rotated in the expansion and retraction directions, which also helps to reduce the Y-direction layout space of the electric pedal.

[0062] Based on the overall introduction above, specifically, it should be pointed out that, for the electric pedal adopting the driving mechanism of this embodiment, the stretching of the pedal 4 mentioned above, that is, under the drive of the driving component 100, the pedal 4 is deployed outward relative to the vehicle body, which is "stretching", and on the contrary, the pedal 4 is retracted to one side of the vehicle body, which is "pulling". Therefore, the stretching of the pedal 4 represents the deployment and retraction of the pedal 4 driven by the driving component 100.

[0063] As for the "rotation" of the above-mentioned pedal 4, under the drive of the driving component 100, the pedal 4 can not only be "stretched" in the unfolding and retracting directions, but also can make the pedal 4 flip over compared to the horizontal plane during the "stretching" process, so that it enters a horizontal state or close to horizontal after unfolding, and forms a certain angle with the horizontal plane after retracting.

[0064] In addition, in this embodiment, based on the connecting rods in the connecting rod assembly 200 described above, and the connection between the vehicle body frame bracket 1 and the pedal base frame 3, under the rotation drive of the driving assembly 100, the transmission connecting rod 6 can drive the second connecting rod 7 and the third connecting rod 5 to rotate and move relative to the vehicle body fixed bracket 1, and the second connecting rod 7 can drive the first connecting rod 8 to rotate, and the first connecting rod 8 and the third connecting rod 5 can jointly drive the pedal base frame 3 to rotate and move relative to the vehicle body fixed bracket 1.

[0065] At this time, the second connecting rod 7 and the third connecting rod 5 move relative to the vehicle body fixing bracket 1, and the pedal base frame 3 moves relative to the vehicle body fixing bracket 1, that is, the second connecting rod 7, the third connecting rod 5 and the pedal base frame 3 are stretched in the direction of the pedal 4 being deployed and retracted. Of course, under the drive of the driving assembly 100, and under the cooperation of the vehicle body fixing bracket 1 and the pedal base frame 3, through the transmission of each connecting rod in the connecting rod assembly 100, this embodiment can realize the driving of the pedal 4 to realize its deployment or retraction.

[0066] At the same time, it can be understood that under the rotation drive of the driving assembly 100, the transmission connecting rod 6 drives the second connecting rod 7 and the third connecting rod 5 to rotate and stretch, the second connecting rod 7 drives the first connecting rod 8 to rotate, and the first connecting rod 8 and the third connecting rod 5 jointly drive the pedal base 3 to rotate and stretch, which can specifically realize the stretching and rotation drive of the pedal 4, so as to achieve the desired purpose of reducing space occupancy on the basis of meeting the use requirements of the electric pedal.

[0067] In this embodiment, the vehicle body fixing bracket 1 is fixed on the vehicle body as the installation base of the electric pedal, and generally speaking, it is combined with Figure 4 As shown, the driving assembly 100 is also mounted and fixed on the vehicle body fixing bracket 1 to realize the setting of the driving assembly 100 on the vehicle. The pedal base 3 is used to install the pedal 4 to realize the connection between the pedal 4 and the driving mechanism, and realize the setting of the pedal 4 in the overall electric pedal.

[0068] In a specific implementation, in order to realize the installation of the vehicle body fixing bracket 1 on the vehicle body, for example, a plurality of mounting holes may be provided on the vehicle body fixing bracket 1, and the vehicle body fixing bracket 1 may be fixedly connected to the vehicle body by bolts passing through the mounting holes. For the fixing installation of the driving component 100 on the vehicle body fixing bracket 1, for example, a plurality of fixing columns 21 may be provided on the vehicle body fixing bracket 1, and a threaded connection hole may be provided at the end of each fixing column 21, and then the driving component 100 may be fixed to each fixing column 21 by screws.

[0069] Continue as Figure 5 and Figure 6 As shown in the figure, in this embodiment, the hinge point b between the transmission link 6 and the second link 7, and the hinge point a between the transmission link 6 and the third link 5 are also coaxially arranged, and in the X direction of the vehicle, the transmission link 6 is located on one side of the third link 5, and the second link 7 is located on the other side of the third link 5 relative to the transmission link 6.

[0070] At this time, it can be understood that the hinge point b between the transmission link 6 and the second link 7 and the hinge point a between the transmission link 6 and the third link 5 are coaxially arranged, which can simplify the hinge structure of the transmission link 6, the second link 7 and the third link 5. In the X-direction of the vehicle, the transmission link 6 and the second link 7 are arranged on two opposite sides of the third link 5, which can make the connecting rod assembly 200 more compact in structure, which is conducive to reducing the space occupied by the connecting rod assembly 200.

[0071] Of course, in addition to making the transmission link 6 and the second link 7 separately arranged on two opposite sides of the third link 5, in other feasible implementation forms, based on the different settings of the drive assembly 100, the transmission link 6 and the third link 5 are separately arranged on two opposite sides of the second link 7, and under the condition that the arrangement requirements of the link assembly 200 are met, the transmission link 6 is located between the second link 7 and the third link 5. It is also possible. In addition, when the transmission link 6 is located between the third link 5 and the second link 7, it can be understood that by making both sides of the transmission link 6 bear force, the stability of the transmission of the transmission link 6 can also be improved, and the stability of the operation of the driving mechanism can be improved.

[0072] In this embodiment, the hinge point c between the first link 8 and the pedal chassis 3, and the hinge point d between the third link 5 and the pedal chassis 3 are arranged at intervals in the width direction of the pedal 4. Figure 8 and Fig. 9 As shown in FIG. 1 , the first connecting rod 8 , the second connecting rod 7 , the third connecting rod 5 and the pedal chassis 3 form a four-bar linkage. Meanwhile, the transmission connecting rod 6 , the second connecting rod 7 , the first connecting rod 8 and the vehicle body fixing bracket 1 also form a four-bar linkage.

[0073] At this time, the first connecting rod 8, the second connecting rod 7, the third connecting rod 5 and the pedal base frame 3 form a four-bar linkage, and the transmission connecting rod 6, the second connecting rod 7, the first connecting rod 8 and the vehicle body fixing bracket 1 form a four-bar linkage. It can be understood that it can form a double cantilever form through the design of a double four-bar linkage. Compared with the single cantilever form formed by the existing four-bar linkage, it can improve the space utilization rate of the connecting rod mechanism, so as to help reduce the space occupied by the driving mechanism of this embodiment and the electric pedal using it.

[0074] In addition, if Figure 7 As shown in the figure, as a preferred implementation form, the first connecting rod 8 of this embodiment is similar to the "door" shape in structure, and has two connecting rod arms 81 arranged oppositely, and one end of the second connecting rod 7 hinged to the first connecting rod 8, and the part where the pedal base 3 and the first connecting rod 8 are hinged, are both located between the two connecting rod arms 81.

[0075] By making the first connecting rod 8 have two connecting rod arms 81 arranged relatively to each other, and making the second connecting rod 7 and the part where the pedal base 3 is hinged to the first connecting rod 8 be located between the two connecting rod arms 81, the reliability of the hinge between the second connecting rod 7 and the pedal base 3 and the first connecting rod 8 can be increased. At the same time, it can also make the relative movement between the first connecting rod 8, the second connecting rod 7 and the pedal base 3 smoother, which helps to improve the use effect of the driving mechanism.

[0076] It is worth noting that in this embodiment, in the specific implementation, the articulation between the transmission link 6 and the second link 7 and the third link 5, the articulation between the third link 5 and the first link 8 and the pedal base 3, the articulation between the second link 7 and the first link 8, and the articulation between the first link 8 and the vehicle body fixing bracket 1, all adopt the existing conventional articulation form, for example, the articulation axis that crosses the components to be articulated can be used for connection. At the same time, in order to reduce the wear between the articulation axis and each link and the vehicle body fixing bracket 1 and the pedal base 3, wear-resistant structures such as bushings can also be set at each articulation position.

[0077] In this embodiment, as a preferred implementation form, the above-mentioned driving assembly 100 may, for example, include a driving motor 2 fixedly connected to a vehicle body fixing bracket 1, and a reducer 9 connected to the driving motor 2, and the transmission connecting rod 6 is also connected to a driving shaft 91 serving as a power output end of the reducer 9.

[0078] In this way, the driving assembly 100 is composed of the driving motor 2 and the reducer 9, which has a simple structure and low cost, and can reliably drive the pedal 4 to move. Figure 4 As shown, based on the multiple fixing columns 21 set on the vehicle body fixing bracket 1, the driving motor 2 and the reducer 9 in the driving assembly 100 can be respectively connected to some of the fixing columns 21 to achieve the fixing of the entire driving assembly 100 on the vehicle fixing bracket 1.

[0079] In addition, for the connection between the transmission connecting rod 6 and the above-mentioned drive shaft 91, a connection hole can generally be set at one end of the transmission connecting rod 6, so that the drive shaft 91 is inserted into the connection hole, and a flat key is set between the drive shaft 91 and the transmission connecting rod 6 to ensure reliable transmission between the two. Of course, in addition to setting the flat key, it is also feasible to make the connection holes on the drive shaft 91 and the transmission connecting rod 6 in a spline matching form to achieve reliable transmission between the two.

[0080] When the electric pedal drive mechanism of this embodiment is working, as mentioned above, when receiving the pedal start signal from the vehicle controller, under the drive of the drive component 100, that is, the drive motor 2, the transmission connecting rod 6 drives the second connecting rod 7 and the third connecting rod 5 to rotate and stretch in the Y direction of the whole vehicle, the second connecting rod 7 drives the first connecting rod 8 to rotate, and the first connecting rod 8 and the third connecting rod 5 jointly drive the pedal base frame 3 to rotate and stretch in the Y direction of the whole vehicle, so that the pedal 4 can be unfolded.

[0081] When the pedal retraction signal is received from the vehicle controller, the drive motor 2 rotates in the reverse direction. Driven by the drive motor 2, the transmission connecting rod 6 drives each connecting rod to move in the reverse direction. Finally, the first connecting rod 8 and the third connecting rod 5 jointly drive the pedal base 3 to rotate and stretch in the Y direction of the entire vehicle, thereby realizing the retraction of the pedal 4.

[0082] When the pedal 4 is unfolded, the state of the entire electric pedal can be as follows: Figure 1 and Figure 3 As shown in FIG. 1 , when the pedal 4 is retracted, the state of the entire electric pedal can be as follows: Figure 2 And, combined with Fig.11 As shown in the figure, the six-link mechanism as described above is adopted. Through relevant verification, after the pedal 4 is retracted, the arrangement space D of the electric pedal in the Y direction of the whole vehicle is located below 150 mm. Compared with the existing 200 mm, the Y-direction arrangement space can be greatly reduced.

[0083] To sum up, the electric pedal drive mechanism of the present embodiment adopts the above design. By making the connecting rod assembly include the first connecting rod 8, the second connecting rod 7, the third connecting rod 5 and the transmission connecting rod 6, it can form a six-link mechanism together with the vehicle body fixing bracket 1 and the pedal base frame 3. It can not only provide a new type of electric pedal drive structure, but also can make the pedal 4 both stretchable and rotated in the Y direction under the transmission of the six-link mechanism, which helps to reduce the Y-direction layout space of the electric pedal, makes it easier to realize installation on vehicles with smaller vehicle body space, and is beneficial to improving the application effect of the electric pedal.

[0086] Among them, still combined Figure 1 As shown, the pedal assembly 300 includes a pedal base 3 and a pedal 4 connected to the pedal base 3 .

[0087] Furthermore, in specific implementation, the pedal 4 can generally be fixedly connected to the pedal chassis 3 through a connecting assembly, and preferably, in this embodiment, a pre-hanging structure that bites together can be provided between the pedal 4 and the pedal chassis 3. In this way, by providing a pre-hanging structure that bites together between the pedal 4 and the pedal chassis 3, it cooperates with the above-mentioned connecting assembly, which can facilitate the connection between the pedal 4 and the pedal chassis 3, and also can improve the stability of the connection between the pedal 4 and the pedal chassis 3.

[0088] like Fig.10 As shown in , as a feasible implementation form, the above-mentioned connection assembly may include, for example, a connection nut 400 and a connection bolt 500. The connection nut 400 is arranged on the pedal 4, and the connection bolt 500 is passed through the connection through hole on the pedal base 3 and is screwed together with the connection nut 400 to achieve a fixed connection between the pedal 4 and the pedal base 3.

[0089] But still Fig.10As shown, as a feasible implementation form, the above-mentioned pre-hanging structure may include, for example, a groove 42 provided at the bottom of the pedal 4, and a protrusion 31 correspondingly provided on the pedal base frame 3. The groove 42 and the protrusion 31 may be designed to be long strips. When the pedal 4 is connected to the pedal base frame 3, the protrusion 31 is firstly inserted into the groove 42 to pre-hang the pedal 4 on the pedal base frame 3, and then the connecting bolt 500 is inserted and fixedly connected with the connecting nut 400.

[0090] In this embodiment, during specific implementation, as a preferred implementation form, the pedal 4 can be made of, for example, an extruded aluminum profile, so as to facilitate the preparation of the pedal 4, while also improving the structural strength of the pedal 4 and helping to achieve its lightweight design.

[0091] In addition, as a preferred implementation form, this embodiment can also provide an anti-skid structure on the tread surface of the pedal 4. The anti-skid structure can be, for example, an anti-skid strip 41 formed on the pedal 4, and by providing the anti-skid structure on the tread surface of the pedal 4, it is obvious that it can increase the safety of the driver and passengers when using the electric pedal.

[0092] The electric pedal of this embodiment, by adopting the electric pedal driving mechanism in the first embodiment, helps to reduce the Y-direction arrangement space of the electric pedal, and can facilitate the arrangement of the electric pedal on the vehicle, thereby improving the application effect of the electric pedal.

[0093] In addition, the present embodiment also relates to a vehicle, on which the above-mentioned electric pedal is provided.

[0094] The vehicle of this embodiment has the technical advantages of the above-mentioned electric pedal, which will not be repeated here.

[0095] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
