Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] The support arm assembly provided in the present application is applied to an electric pedal device and includes: a support arm, the support arm includes a first mounting portion, a second mounting portion, and a main body portion connected between the first mounting portion and the second mounting portion. A first recess structure is provided at the connection between the second mounting portion and the main body portion, and the first recess structure is used to fit the pedal assembly in the retracted state; wherein, one end of the support arm is used to be hinged to a mounting seat, and the other end of the support arm is used to be hiddenly hinged to the pedal assembly. In this way, the electric pedal device neither occupies the foot surface area of the pedal assembly nor can achieve a compact contraction, and ensures the self-locking ability during contraction.

[0033] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a vehicle provided by some embodiments of the present application. Existing vehicles such as SUVs and / or MPVs generally need to be equipped with pedals to assist passengers in getting in and out of the cabin due to their relatively high ground clearance of the chassis. Existing pedals generally include fixed pedals and electric pedals. Electric pedals are popular among users because they can automatically extend when the door is opened to assist passengers in getting in and out of the cabin conveniently and comfortably, and can automatically retract when the door is closed to ensure the passing performance and aesthetic appearance of the vehicle. The vehicle 1000 provided in the present application is a vehicle model with a large distance between the chassis and the ground. The vehicle 1000 may include, but is not limited to, an electric pedal device 100 and a vehicle body 200. The electric pedal device 100 is fixed to the vehicle body 200 to assist passengers in getting in and out of the cabin conveniently and comfortably. Among them, the electric pedal device 100 belongs to a side-swing type electric pedal.

[0034] Please refer to Figure 1 and Figure 2 , Figure 2 which is a schematic structural diagram of the electric pedal device in the deployed state provided by some embodiments of the present application. The electric pedal device 100 may include, but is not limited to, a mounting seat 110, a support arm assembly 120, a pedal assembly 130, and a driving device 140. There are at least two support arm assemblies 120. One end of the support arm assembly 120 is hinged to the mounting seat 110. The other end of the support arm assembly 120 is hiddenly hinged to the pedal assembly 130. The driving device 140 is fixed to the mounting seat 110 and is drivingly connected to a support arm assembly 120 to further drive the pedal assembly 130 to extend or retract relative to the vehicle body 200.

[0035] Among them, the hidden hinge between the support arm assembly 120 and the pedal assembly 130 in this application means that when the electric pedal device 100 is in the deployed state, when viewed from the side of the pedal assembly 130 facing away from the vehicle body 200, the hinge connection structure between the support arm assembly 120 and the pedal assembly 130 is not visible.

[0036] In this embodiment, there are three support arm assemblies 120. The three support arm assemblies 120 are arranged along the extending direction of the pedal assembly 130 to enhance the load-bearing capacity of the electric pedal device 100. The driving device 140 is drivingly connected to the support arm assembly 120 located in the middle relative to the other two support arm assemblies 120, so as to reduce the requirement for the self-locking ability of the driving device 140 when the pedal assembly 130 is in the retracted state, and to balance the anti-pinch and anti-collision response sensitivity at each position of the pedal assembly 130.

[0037] In some other embodiments, there may be two support arm assemblies 120. One support arm assembly 120 is hiddenly hinged to one end of the pedal assembly 130, and the other support arm assembly 120 is hiddenly hinged to the other end of the pedal assembly 130.

[0038] Please refer to Figures 3 - 7 , Figure 3 which is a schematic structural view of the electric pedal device in the retracted state provided by some embodiments of this application, Figure 4 which is an exploded schematic view of the electric pedal device provided by some embodiments of this application, Figure 5 which is Figure 4 a partial enlarged view of the electric pedal device at area A, Figure 6 which is a schematic structural view of the support arm assembly provided by some embodiments of this application, Figure 7 which is an exploded schematic view of the support arm assembly provided by some embodiments of this application. The support arm assembly 120 may include but is not limited to a support arm 121, a first rotating shaft 122, a second rotating shaft 123, and a fastener 124. One end of the support arm 121 is hinged to the mounting seat 110 through the first rotating shaft 122 so as to be able to rotate relative to the mounting seat 110. The other end of the support arm 121 is hiddenly hinged to the pedal assembly 130 through the second rotating shaft 123 to drive the pedal assembly 130 to deploy or retract, and at the same time does not occupy the foot surface area of the pedal assembly 130. The first rotating shaft 122 is fixed to one end of the support arm 121 through a fastener 124. The second rotating shaft 123 is fixed to the other end of the support arm 121 through another fastener 124.

[0039] Further, the support arm 121 may include, but is not limited to, a first mounting portion 1211, a second mounting portion 1212, and a main body portion 1213. The main body portion 1213 is connected between the first mounting portion 1211 and the second mounting portion 1212. A first recessed structure 1214 is provided at the connection between the second mounting portion 1212 and the main body portion 1213. When the pedal assembly 130 is in the retracted state, the pedal assembly 130 is fitted into the first recessed structure 1214, so that the pedal assembly 130 is relatively contracted and compact with respect to the mounting base 110, thereby ensuring the self-locking ability of the electric pedal device 100 when it is in the retracted state.

[0040] It can be understood that the driving device 140 includes a link mechanism capable of self-locking. When the pedal assembly 130 is in the retracted state, only when the pedal assembly 130 is contracted sufficiently compactly relative to the mounting base 110 can the link mechanism in the driving device 140 achieve self-locking. However, in the existing side-swing type electric pedal device, when the support arm assembly and the pedal assembly adopt a hidden hinge connection structure, it is difficult for the pedal assembly to achieve a compact contraction. The support arm assembly 120 provided in the present application is provided with a first recessed structure 1214 at the connection between the second mounting portion 1212 and the main body portion 1213, so that on the premise of a hidden hinge between the support arm assembly 120 and the pedal assembly 130, the pedal assembly 130 can still be contracted compactly, thereby ensuring the self-locking ability of the electric pedal device 100 in the retracted state.

[0041] In this embodiment, a second recessed structure 1215 is further provided at the connection between the first mounting portion 1211 and the main body portion 1213. The second recessed structure 1215 has an opposite orientation to the first recessed structure 1214. When the pedal assembly 130 is in the retracted state, a part of the structure of the mounting base 110 is fitted into the second recessed structure 1215, so that the pedal assembly 130 is relatively contracted more compactly with respect to the mounting base 110, thereby further ensuring the self-locking ability of the electric pedal device 100 in the retracted state.

[0042] Optionally, the interior of the support arm 121 may be hollowed out, so that the support arm assembly 120 is lighter, reducing the mass of the electric pedal device 100 as a whole, and at the same time reducing the output power requirement for the driving device 140.

[0043] Further, the first mounting portion 1211 is provided with a first through hole 1211a. The first rotating shaft 122 passes through the first through hole 1211a. The first rotating shaft 122 is fastened to the first mounting portion 1211 by a fastener 124. Both ends of the first rotating shaft 122 are hinged to the mounting base 110. The second mounting portion 1212 is provided with a second through hole 1212a. The second rotating shaft 123 passes through the second through hole 1212a. The second rotating shaft 123 is fastened to the second mounting portion 1212 by another fastener 124. Both ends of the second rotating shaft 123 are hiddenly hinged to the pedal assembly 130.

[0044] Among them, the center lines of the first through hole 1211a and the second through hole 1212a are parallel to each other. When the mounting seat 110 is fixed to the vehicle body 200, the center line of the first through hole 1211a is inclined relative to the horizontal plane. In this way, when the driving device 140 drives the support arm assembly 120, the pedal assembly 130 can swing outward and move downward and / or swing inward and move upward relative to the vehicle body 200 and / or the mounting seat 110. Among them, swinging outward means swinging away from the vehicle body 200 and / or the mounting seat 110. Swinging inward means swinging closer to the vehicle body 200 and / or the mounting seat 110. Moving downward means moving closer to the ground. Moving upward means moving away from the ground.

[0045] Furthermore, boss structures 129 are provided at both ends of the first through hole 1211a, so that the first mounting portion 1211 is in sufficient contact with the bushing at the mounting seat 110. Boss structures 129 are also provided at both ends of the second through hole 1212a, so that the second mounting portion 1212 is in sufficient contact with the bushing at the pedal assembly 130.

[0046] For the support arm assembly 120 connected to a link mechanism with self-locking ability, the support arm assembly 120 further includes a ball head screw 125 and a nut 126. The nut 126 is screwed onto the ball head screw 125. The first mounting portion 1211 is further provided with a third through hole 1211b. The ball head screw 125 passes through the third through hole 1211b. The screw portion 1252 of the ball head screw 125 is screwed onto the nut 126, so that the ball head screw 125 is fixed to the first mounting portion 1211.

[0047] Optionally, the center line of the third through hole 1211b is parallel to the center line of the first through hole 1211a, so as to facilitate improving the force at the hinge joint between the first mounting portion 1211 and the mounting seat 110.

[0048] In particular, for the active support arm assembly (the support arm assembly 120 drivenly connected to the driving device 140), the ball head portion 1251 of the ball head screw 125 is ball-jointed with the driving device 140.

[0049] Furthermore, a boss structure 129 is provided at one end of the third through hole 1211b close to the driving device 140, so that the first mounting portion 1211 is in sufficient contact with the ball head portion 1251 of the ball head screw 125. A groove structure 1211c is provided at the other end of the third through hole 1211b far from the driving device 140. The nut 126 is arranged in the groove structure 1211c to prevent the nut 126 from protruding relative to the first mounting portion 1211 and affecting the retraction of the pedal assembly 130.

[0050] In some other embodiments, the support arm assembly 120 further includes at least one buffer pad. The at least one buffer pad is disposed on the first mounting portion 1211 such that the pedal assembly 130 can be in buffered contact with the mounting base 110 when in the retracted state and / or the deployed state, thereby reducing the noise generated when the pedal assembly 130 retracts and deploys.

[0051] In this embodiment, the support arm assembly 120 includes a first buffer pad 127 and a second buffer pad 128. A first receiving groove 1211d is provided on one side of the first mounting portion 1211. A partial structure of the first buffer pad 127 is received in the first receiving groove 1211d to ensure that the pedal assembly 130 is in place when retracting or deploying while achieving buffered contact. A second receiving groove 1211e is provided on the other side of the first mounting portion 1211. A partial structure of the second buffer pad 128 is received in the second receiving groove 1211e to ensure that the pedal assembly 130 is in place when retracting or deploying while achieving buffered contact.

[0052] The support arm assembly 120 provided in this application is applied to the electric pedal device 100 and includes: a support arm 121, the support arm 121 includes a first mounting portion 1211, a second mounting portion 1212, and a main body portion 1213 connected between the first mounting portion 1211 and the second mounting portion 1212. A first recess structure 1214 is provided at the connection between the second mounting portion 1212 and the main body portion 1213, and the first recess structure 1214 is used to fit the pedal assembly 130 in the retracted state; wherein, one end of the support arm 121 is used to be hinged to the mounting base 110, and the other end of the support arm 121 is used to be hiddenly hinged to the pedal assembly 130. In this way, the electric pedal device 100 neither occupies the foot surface area of the pedal assembly 130 nor can achieve a compact contraction and ensure the self-locking ability during contraction.

[0053] The above are only some embodiments of this application, and thus do not limit the protection scope of this application. Any equivalent device or equivalent process transformation made using the content of the specification and drawings of this application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of this application.
