Description

Technical Field

[0001] The utility model relates to the technical field of automobile door pedals, in particular to a door pedal suitable for a business car with an electric side sliding door, which can automatically slide out or retract horizontally along the side direction following the opening and closing of the electric side sliding door. Background Art

[0002] Business cars are equipped with lateral pedals for assisting stepping, which are generally retractable. Under the control of the main control system, when the door is opened, the power mechanism of the lateral pedal drives the pedal to extend, and when the door is closed, the power mechanism drives the pedal to retract.

[0003] For example, the technical solution recorded in the utility model patent with publication number CN206914239U and name “Automobile with Electric Retractable Pedal” is configured by setting an active four-bar mechanism that is cantilevered mounted on the vehicle chassis and driven by a motor, and a follower four-bar mechanism, so that the movement trajectory of the pedal surface is matched with the diagonal of the rectangle formed by the unfolded size and the sunken size. In other words, the pedal can be swung out from under the vehicle chassis or swung back under the chassis.

[0004] In this solution, the vertical cantilever swing occupies the deployment / retraction space and the motor installation space, so that the electric telescopic pedal occupies a total height of no less than 8 cm at the bottom of the vehicle, which greatly affects the vehicle's passability. On the other hand, in order to reduce the height occupied by the vertical swing of the pedal, the width of the pedal is relatively narrow, making it inconvenient and unstable to step on the pedal.

DETAILED DESCRIPTION

[0047] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0048] Embodiment: The follow-up side-sliding telescopic pedal provided in this embodiment is suitable for business cars with electric side-sliding doors. Figure 1-3 The structure of the follow-up side-sliding telescopic foot pedal of this embodiment in three states is shown as a whole. As a whole, the follow-up side-sliding telescopic foot pedal of this embodiment includes a foot pedal 3 installed on the vehicle body frame beam 1 through a guide system 4, a track 6 installed on the foot pedal 3, and a transmission system 5 installed on the door inner panel of the side sliding door 2. The vehicle body frame beam 1 has a length extending along the y-axis direction, and the side sliding door 2 is located outside the vehicle body frame beam 1 in the x-axis direction. The transmission system 5 can transmit the sliding action of the side sliding door 2 to the pedal 3 through the track 6 to drive the pedal 3 to slide out and recover. Preferably, in order to strengthen the structural strength and improve the support strength that the foot pedal 3 can improve (that is, the allowable supporting weight of the foot pedal 3), the guide system 4 is installed on the vehicle body frame beam 1 through a mounting bracket 9. Further preferably, the follow-up side-sliding telescopic pedal can also include a door side guard plate 7 and a guard plate pedal 8, and the guard plate pedal 8 can extend the stepping width and increase the stepping width after the foot pedal 3 slides out.

[0049] The foot pedal 3 can be any feasible plate structure in the prior art. When the side sliding door 2 is in a closed state, the foot pedal 3 is located on the inner side of the side sliding door 2 in the x-axis direction and on the lower side of the vehicle body frame beam 1 .

[0050] The guide system 4 includes a set of parallelogram four-bar mechanisms 41 configured to mount the footrest 3 on the vehicle body frame 1. The parallelogram four-bar mechanisms 41 can limit the movement of the footrest 3 within the plane where its own width is located. In other words, the parallelogram four-bar mechanisms 41 allow the footrest 3 to slide out or be retracted in a swinging manner only within the plane where its own width is located.

[0051] The transmission system 5 includes a pull rod 51 installed at the bottom of the side sliding door 2 and a transmission component 52 arranged at the free end of the pull rod 51 .

[0052] The track 6 is installed on the foot pedal 3. The path formed by the extension of the track 6 is the same as the movement trajectory formed by the transmission component 52 during the opening of the side sliding door 2. The track 6 is configured to cooperate with the transmission component 52 so that the foot pedal 3 is extended or retracted relative to the vehicle body frame 1 as the transmission component 52 moves.

[0053] Reference Figure 4As shown, the follow-up side-sliding telescopic foot pedal of the above technical solution can be matched with any electric side sliding door of a commercial vehicle in the prior art. The sliding action of the side sliding door 2 includes three action sections: (1) a straight line tilting sliding out that can form two sub-motions in the x-axis direction and the y-axis direction, (2) an arc tilting sliding out that can form two sub-motions in the x-axis direction and the y-axis direction, and (3) a translational sliding along the y-axis direction. Therefore, the track 6 has a straight line tilting section 6a that is the same as the first section of the motion trajectory, a arc tilting section 6b that is the same as the second section of the motion trajectory, and a straight line section 6c that is the same as the third section of the motion trajectory. Figure 4 , the motion trajectory of the sliding door (transmission component 52 ) and the guide trajectory of the track 6 are roughly shown.

[0054] As the side sliding door 2 performs the first and second movements, the transmission component 52 can transmit the movement of the side sliding door 2 to the foot pedal 3 by cooperating with the track 6, and under the limitation of the parallelogram four-bar mechanism 41, the foot pedal 3 slides out laterally along a partial arc trajectory in the xy plane. As the third movement is performed, the transmission component 52 can translate along a guide path parallel to its movement trajectory without causing displacement of the foot pedal 3.

[0055] The sliding out and retracting movement of the follow-up side-sliding telescopic foot pedal provided in this embodiment is limited to the xy plane, so there is no need to reserve height space at the bottom of the frame to match the swing arm in the height direction. At the same time, this follow-up side-sliding telescopic foot pedal is not equipped with a motor, so there is no need to reserve height space at the bottom of the frame to install the motor. With the above two improvements, the total thickness (or the total occupied height at the bottom of the frame) of the follow-up side-sliding telescopic foot pedal provided in this embodiment is only 3-4 cm, which can reduce the impact of the setting of the telescopic foot pedal on the vehicle's passability to a certain extent.

[0056] In the following, a follow-up side-sliding telescopic pedal provided in this embodiment is specifically described in the order of first explaining the structure and assembly relationship of the guide system 4, the foot pedal 3, and the track 6 installed on the vehicle body frame 1, then explaining the structure and assembly relationship of the transmission system 5 installed on the door inner panel of the side sliding door 2, and finally explaining the transmission relationship between the transmission system 5 and the foot pedal 3.

[0057] Reference Figure 5 , Figure 6 As shown, the guiding system 4 includes a set of parallelogram four-bar mechanisms 41 , and in some preferred cases, also includes an auxiliary hinge mechanism 42 and a pair of elastic limiters 43 .

[0058] The parallelogram four-bar mechanism 41 can be any feasible structure in the prior art, for example, including a pair of crank connecting rods. One end of the crank connecting rod is hinged to the bottom surface of the vehicle body frame beam 1, and the other end is hinged to the bottom surface of the foot pedal 3, so that the parallelogram four-bar mechanism 41 can limit the movement of the foot pedal 3 to the swing within the plane where its own width is located (xy plane).

[0059] The auxiliary hinge mechanism 42 is located between a pair of crank links of the parallelogram four-bar mechanism 41. The auxiliary hinge mechanism 42 includes a first auxiliary link 421 and a second auxiliary link 422 that are hinged to each other, the mounting end of the first auxiliary link 421 is hinged to the bottom surface of the vehicle body frame beam 1, and the mounting end of the second auxiliary link 422 is hinged to the bottom surface of the footrest 3, so that the support of the parallelogram four-bar mechanism 41 to the footrest 3 can be strengthened.

[0060] The elastic limiting member 43 is screwed to the bottom surface of the vehicle body frame beam 1 and is disposed on both sides of the parallelogram four-bar mechanism 41 to limit the horizontal swing amplitude of the parallelogram four-bar mechanism 41 .

[0061] Preferably, in order to enhance the structural strength and improve the support strength that the footrest 3 can improve (i.e., the weight allowed to be supported by the footrest 3), the follow-up side-sliding telescopic footrest further includes a mounting bracket 9 configured to provide installation space and support for the guide system 4, and a secondary mounting bracket 95 that cooperates with the mounting bracket 9. Specifically, the mounting bracket 9 includes a bracket vertical plate 91, a bracket horizontal plate 92 formed by bending from the bottom of the bracket vertical plate 91, and a bracket L-shaped extension plate 93 formed by bending from one side of the bracket horizontal plate 92 toward the side opposite to the bracket vertical plate 91. The secondary mounting bracket 95 includes a secondary bracket horizontal plate 951 and a secondary bracket L-shaped extension plate 952 formed by bending from the side of the secondary bracket horizontal plate 951.

[0062] Generally, the side and bottom surfaces of the vehicle body frame beam 1 are provided with reserved holes. The bracket vertical plate 91 is provided with a plurality of mounting holes corresponding to the reserved holes on the side surface of the vehicle body frame beam 1. The bracket vertical plate 91 is bolted to the side surface of the vehicle body frame beam 1 through the matching mounting holes and the reserved holes. Preferably, the bracket vertical plate 91 includes four mounting holes.

[0063] The bracket cross plate 92 and the auxiliary bracket cross plate 951 are provided with several mounting holes corresponding to the reserved holes on the bottom surface of the vehicle body frame beam 1, and the bracket cross plate 92 is molded to form three hinge cavities. The bracket cross plate 92 and the auxiliary bracket cross plate 951 are screwed and installed on the bottom surface of the vehicle body frame beam 1 through the matching of the mounting holes and the reserved holes. After assembly, the bracket L-shaped extension plate 93 and the auxiliary bracket L-shaped extension plate 952 are overlapped, and the three hinge cavities and the bottom surface of the vehicle body frame beam 1 are surrounded to form three hinge spaces. The mounting ends of the crank connecting rod and the first auxiliary connecting rod 421 of the parallelogram four-bar mechanism 41 extend into the hinge space and are respectively hinged to the bracket cross plate 92 and the auxiliary bracket cross plate 951.

[0064] In this preferred embodiment, the elastic limiting member 43 is threadedly mounted on the auxiliary mounting bracket 95 .

[0065] The setting of the mounting bracket 9 can make full use of the original reserved holes on the bottom of the vehicle body and decompose the pedaling force on the foot pedal 3 to seven connection points (four screw connection points on the side of the vehicle body frame 1 and three hinged connection points on the bottom), thereby increasing the maximum allowable load-bearing weight of the foot pedal 3 and improving the stability of the foot pedal 3 during the pedaling process.

[0066] Reference Figure 7 , Figure 8 As shown, the pedal 3 includes a pedal bottom plate 31 and a pedal surface plate 32 fixedly covered on the surface of the pedal bottom plate 31 by a clamping method. Compared with the technical solution in the prior art in which the surface plate is fixedly covered on the bottom plate by screwing, the clamping method can further reduce the thickness of the pedal 3 and the overall thickness of the telescopic pedal, thereby reducing the height space occupied by the telescopic pedal at the bottom of the vehicle. By means of the clamping assembly method, the overall thickness of the telescopic pedal of this embodiment can be further reduced to 3 cm.

[0067] Specifically, a plurality of snap-in holes 33 are provided on the pedal bottom plate 31, and snap-in blocks 35 cooperating with the snap-in holes 33 are provided on the bottom surface of the pedal top plate 32. The snap-in holes 33 are "convex" through holes, including a flared opening and a narrow opening that are connected. The snap-in blocks 35 are T-shaped snap-in blocks, which can be inserted into the flared opening of the snap-in holes 33, and snap into the narrow opening of the snap-in holes 33 as the pedal top plate 32 and the pedal bottom plate 31 slide relative to each other.

[0068] Preferably, two rows of engaging holes 33 are formed on the pedal bottom plate 31 , and the two rows of engaging holes 33 are arranged alternately.

[0069] In order to further prevent the pedal bottom plate 31 from being separated from the pedal surface plate 32, a plurality of plug holes 34 are provided on the pedal bottom plate 31, and a slot piece 36 matching the plug holes 34 is provided on the bottom surface of the pedal surface plate 32. The plug holes 34 are quadrilateral holes, and the slot piece 36 is an "L"-shaped insert piece, which can be inserted into the plug holes 34, and as the pedal surface plate 32 and the pedal bottom plate 31 slide relative to each other, the pedal bottom plate 31 on one side of the plug hole 34 is inserted into the slot of the slot piece 36.

[0070] The plugging holes 34 may be selected as parallelogram holes 341 or rectangular holes 342 . In other words, the plugging holes 34 may be composed entirely of parallelogram holes 341 or rectangular holes 342 . The plugging holes 34 provided in this embodiment include several parallelogram holes 341 and several rectangular holes 342 .

[0071] When the plug hole 34 is a parallelogram hole 341, the corresponding slot plate 36 also has a groove top that is a parallelogram and has a groove bottom that is parallel to the hole wall of the parallelogram hole 341, so that after plugging and mating, the hole wall of the plug hole 34 and the groove bottom of the slot plate 36 can abut against each other.

[0072] When the plug hole 34 is a rectangular hole 342 , the corresponding slot plate 36 also has a rectangular top and a slot bottom parallel to the hole wall of the rectangular hole 342 , so that after plugging and mating, the hole wall of the plug hole 34 and the slot bottom of the slot plate 36 can abut against each other.

[0073] Generally, a bottom plate drainage hole is opened on the pedal bottom plate 31, and a surface plate drainage hole is opened on the pedal surface plate 32. When the pedal bottom plate 31 and the pedal surface plate 32 are assembled, the bottom plate drainage hole and the surface plate drainage hole are connected to form a drainage hole 37 of the foot pedal 3.

[0074] Generally, a plurality of anti-slip strips 38 are provided on the surface of the pedal surface plate 32 .

[0075] Generally, a protection strip 39 is mounted on the outer edge of the pedal surface plate 32 in a snap-fit ​​manner.

[0076] Preferably, a pedal light bar 11 is provided at the outer edge of the pedal 3. For example, a mounting groove having the same shape as the light strip of the pedal light bar 11 is provided on the protection bar 39, and the pedal light bar 11 is embedded in the mounting groove and fixed by screwing. The space between the pedal 3 and the vehicle frame beam 1 and the mounting bracket 9 can be suitable for wiring so that the pedal light bar 11 is connected to a power source. The pedal light bar 11 is controlled by the vehicle main control system.

[0077] Reference Fig. 9As shown, the track 6 is screwed and mounted on the bottom surface of the footboard 3, that is, mounted on the bottom surface of the pedal base plate 31. The path formed by the extension of the track 6 is the same as the motion track formed by the transmission component 52 during the opening of the side sliding door 2, so that the track 6 can be divided into a straight inclined section 6a, an arc inclined section 6b, and a straight section 6c in sequence along its guide path. The track 6 is preferably a guide groove type track, so that the structure of the track 6 is composed of a first inner wall surface 61 arranged close to one side of the side sliding door 2, a second inner wall surface 62 arranged relatively far from the side sliding door 2, and a top wall surface 63 connecting the first inner wall surface 61 and the second inner wall surface 62.

[0078] Reference Figure 10-12 As shown, the transmission system 5 includes a pull rod 51 installed at the bottom of the side sliding door 2 and a transmission component 52 arranged at the free end of the pull rod 51. Preferably, the transmission system 5 is installed at the bottom of the door inner plate of the side sliding door 2 and is located at the front end of the side sliding door 2. The transmission component 52 can abut against the first inner wall surface 61 of the track 6, and there is a gap between the transmission component 52 and the second inner wall surface 62. Due to the abutting contact relationship between the transmission component 52 and the first inner wall surface 61, the transmission component 52 can slide out in a straight line and in an arc shape as the side sliding door 2 is opened, and can also move relative to the track 6 along the straight line inclined section 6a and the arc inclined section 6b. During the relative movement of the transmission component 52 and the track 6, the transmission component 52 can pull the foot pedal 3 to extend as it slides sideways, until the transmission component 52 completes the arc inclined section 6b and the foot pedal 3 is fully extended. When the transmission member 52 moves on the straight segment 6c, since the trajectory of the straight segment 6c is parallel to the translational sliding path of the transmission member 52, the transmission member 52 no longer causes the displacement of the footrest 3 until the side sliding door 2 is fully opened. During the extension process, the movement trajectory of the footrest 3 is a partial arc trajectory toward the side and rear, for example, a 35-38° arc trajectory.

[0079] During the closing process of the side sliding door 2, the transmission component 52 moves along the straight section 6c, and the foot pedal 3 remains extended until the transmission component 52 completes the straight section 6c. The transmission component 52 enters the arc inclined section 6b and the straight inclined section 6a, and the transmission component 52 is in contact with the first inner wall surface 61, so that the transmission component 52 can pull the foot pedal 3 to be retracted as it slides sideways. Until the transmission component 52 completes the straight inclined section 6a, the foot pedal 3 is completely retracted, and the side sliding door 2 is completely closed.

[0080] In the above-mentioned matching relationship, the setting of the second inner wall surface 62 and the setting of the gap between the transmission component 52 and the second inner wall surface 62 can allow a certain degree of errors caused by processing, assembly and long-term use.

[0081] The transmission component 52 can be any feasible structure in the prior art, as long as it can move relative to the track 6 with relatively small resistance. The transmission component 52 provided in this embodiment includes a roller 521 that can move along the first inner wall surface 61 of the track 6, and a roller shaft 522 configured to install the roller 521 on the free end of the pull rod 51. Preferably, an adaptation hole 523 is provided on the wheel body of the roller 521, and the setting of the adaptation hole 523 makes it easier for the wheel body of the roller 521 to deform to adapt to possible processing or assembly errors. The top of the transmission component 52 has a wear-resistant component 524 that cooperates with the top wall surface 63. The wear-resistant component 524 is a spherical protrusion of hard plastic, which is suitable for abutting against the top wall surface 63.

[0082] As a preferred embodiment, the pull rod 51 is installed on the side sliding door 2 through a torsion spring hinge structure. The torsion spring hinge structure can be any feasible structure in the prior art, for example, a fixing plate 54 is screwed on the outer facade of the door inner plate, a pair of hinged sheets are integrally formed at the bottom of the fixing plate 54, and another pair of hinged sheets are integrally formed at the top of the pull rod 51. The two pairs of hinged sheets are hingedly connected, and a torsion spring is sleeved on the hinge shaft, and the two ends of the torsion spring are respectively fixed on the hinged sheet of the fixing plate 54 and the hinged sheet of the pull rod 51. The torsion spring is provided with a movement tendency to make the pull rod 51 move closer to the side sliding door 2 so that the transmission component 52 can always abut against the first inner wall surface 61 and the top wall surface 63, so as to prevent the transmission component 52 from being separated from the abutting relationship with the track 6.

[0083] Furthermore, a limiting portion 53 is integrally formed on the mounting end of the pull rod 51, and the limiting portion 53 is driven by the torsion spring hinge structure to abut against the lower side wall surface of the door inner plate of the side sliding door 2. By cooperating with the limiting portion 53 and the door inner plate of the side sliding door 2, the minimum angle between the wheel surface of the roller 521 and the side sliding door 2 can be limited, so that the outer edge of the wheel body of the roller 521 always abuts against the first inner wall surface 61 and the wear-resistant component 524 always abuts against the top wall surface 63, while avoiding interference. The minimum angle between the wheel surface of the roller 521 and the side sliding door 2 that can be limited by the limiting portion 53 depends on the vehicle model, for example, the angle is 85°.

[0084] In some preferred implementations, the foot pedal 3 provided in this embodiment can cooperate with the door edge guard plate 7, and the door edge guard plate 7 is a structure of the prior art.

[0087] A plug-in slot 81 is provided near the outer edge of the bottom surface of the guard pedal 8, and a wear-resistant gasket 82 is mounted in the plug-in slot 81 by snapping or screwing. The outer side edge of the bottom surface of the wear-resistant gasket 82 has ridges. In order to match the ridges of the wear-resistant gasket 82, the axial direction of the anti-slip strip 38 provided in this embodiment is parallel to the line connecting the displacement starting point and the displacement end point of the foot pedal 3, so that during the side sliding and retracting process of the foot pedal 3, the wear-resistant gasket 82 and the anti-slip strip 38 always have a relative movement of linear contact.

[0088] Replay Figure 1-3 In some preferred embodiments, a protective plate 10 may be provided on the bottom surface of the foot pedal 3 to prevent flying stones and mud from entering the telescopic foot pedal and causing the foot pedal 3 to be stuck when being telescopic. The protective plate 10 is fixedly mounted on the bracket cross plate 92 by screwing and plugging.

[0089] As a preferred embodiment, refer to Fig.16 , Fig.17 As shown, the bottom of the door inner plate of the side sliding door 2 is installed with a guard plate inner plate 12 by screwing and / or clamping, which is suitable for protecting the bottom of the side sliding door 2. The guard plate inner plate 12 provided in this embodiment includes an inner plate vertical plate 121, an extended horizontal plate 122 and an extended vertical plate 123, and the extended horizontal plate 122 and the extended vertical plate 123 form a retreat avoidance cavity, which is suitable for avoiding the foot pedal 3 during and after the closing process of the side sliding door 2. Specifically, a fixed plate mounting hole 124 is provided on the side of the inner plate vertical plate 121, and a corner connector 55 is screwed on it, and the other side of the corner connector 55 is screwed to the fixed plate 54. A connecting rod avoidance hole 125 is provided on the extended horizontal plate 122 and the extended vertical plate 123, which is suitable for the pull rod 51 to be hingedly connected to the fixed plate 54 through the pull rod avoidance hole 125.
