Description

Technical Field

[0001] The invention belongs to the technical field of vehicle accessories, in particular to a flip cleaning step and a vehicle. Background Art

[0002] Commercial vehicles are vehicles that are designed and technically used to transport people and goods. Commercial vehicles include all trucks and buses with more than 9 seats, and are divided into five categories: buses, trucks, semi-trailer tractors, incomplete buses, and incomplete trucks. In the entire industry media, the concept of commercial vehicles is mainly defined by their own uses, and commercial vehicles are usually divided into two categories: buses and trucks.

[0003] The cab of a commercial vehicle is relatively high. When the windshield needs to be cleaned before the vehicle is driven, a cleaning step is generally designed at a suitable position at the front end of the vehicle bumper to improve the driver's convenience in operation due to the relatively high position of the windshield of the commercial vehicle.

[0004] In the prior art, in order to improve the ease of use and meet the requirements of space layout, there are usually two ways to design cleaning steps. One is to set a groove on the surface of the bumper, leaving a stepping position on the outer surface of the corresponding height. This design destroys the integrity of the bumper appearance and has high requirements for the rear space. The second is to add a hinge design to the pedal, which can be manually flipped open for people to step on when needed. This method requires the driver to perform manual operation, which affects the driver's experience. However, considering the operating conditions of commercial vehicles, there are poor environments and large bumps, so the pedal will inevitably shake and make abnormal noises during use. Summary of the invention

[0005] In order to solve the problem that the pedal is prone to vibrate and make abnormal noises during use, the present invention provides a flip cleaning step and a vehicle.

[0006] The present invention is achieved through the following technical solutions: A flip cleaning step comprises a mounting base, a movable link mechanism and an anti-skid pedal, wherein the movable link mechanisms are respectively arranged at two ends of the mounting base, and the free ends of the two movable link mechanisms are commonly connected to the anti-skid pedal; The movable link mechanism comprises a driving rod, a movable link 1 and a movable link 2, one end of the driving rod and the movable link 1 are both hinged to the mounting base, and one end of the driving rod and the movable link 1 away from the mounting base are both hinged to the movable link 2; the driving rod is driven by a motor to rotate around the hinge point between the driving rod and the mounting base to realize the extension and retraction of the anti-slip pedal; The driving rod is provided with a locking assembly that cooperates with the movable link one. The locking assembly can lock the movable link one when the driving rod is retracted and swung to the extreme position, and the locking assembly can release the locking state of the movable link one when the driving rod is extended and swung.

[0007] One of the driving rods is driven by a motor to realize the telescopic action of the movable link mechanism through a commonly connected anti-slip pedal; the locking assembly can be locked together with the movable link when the driving rod is in a retracted state, avoiding the jitter caused by the clearance between components and the accompanying abnormal noise problem.

[0008] A further improvement of the present invention is that the locking assembly comprises a driving shaft, a locking plate and a tension spring; the driving shaft is rotatably mounted on the mounting base and fixedly connected to the driving rod; the locking plate is rotatably mounted on the driving rod on one side of the driving shaft; The locking plate is provided with a locking protrusion 2 which can cooperate with the limiting groove 2 on the driving shaft. The limiting groove 2 forms a locking state for the locking protrusion 2 when the driving rod is retracted and swung to the extreme position. The locking plate in the locked state abuts against the movable link 1 to form a relative static state between the movable link 1 and the driving rod. The limiting groove 2 pushes the locking protrusion 2 to the outside of the limiting groove 2 when the driving rod starts to extend and swing, so as to realize the release of the locking state of the movable link 1 by the locking plate.

[0009] A further improvement of the present invention is that a tension spring connecting the locking plate and the driving rod is provided on one side of the driving shaft close to the movable connecting rod 1, and the tension spring pulls the locking protrusion 2 into the limiting groove 2 when the driving rod is about to be retracted and swung to the extreme position.

[0010] A further improvement of the present invention is that the above-mentioned driving shaft is also provided with a limiting groove 1 that can cooperate with a locking protrusion 1 arranged on the locking plate; after the locking protrusion 2 is pushed out to the outside of the limiting groove 2 by the driving shaft, the locking protrusion 1 is snapped into the limiting groove 1 and makes the locking plate and the movable connecting rod 2 in a separated state, and the tension spring in this separated state is in a stretched state to form a state in which the locking protrusion 1 is hooked by the limiting groove 1; when the driving rod of the driving shaft is about to be retracted and swung to the extreme position, the limiting groove 1 releases the hooking state of the locking protrusion 1, and the locking protrusion 2 after the hooking state is released is re-snaps into the limiting groove 2 under the resetting action of the tension spring.

[0011] A further improvement of the present invention is that a locking protrusion three is provided at one end of the locking plate close to the movable connecting rod one, and a limiting groove four is provided on the movable connecting rod one for cooperating with the locking protrusion three when the driving rod is in a retracted limit state.

[0012] A further improvement of the present invention is that a limiting groove five is provided on the driving rod, and the tension spring completely enters into the limiting groove five when the locking protrusion two enters into the limiting groove two.

[0013] A further improvement of the present invention is that a third limiting groove is provided on the driving rod, and the swing amplitude of the locking plate is within the third limiting groove.

[0014] A further improvement of the present invention is that a servo motor is installed at one end of the mounting base, and the output end of the servo motor drives the driving shaft to drive the driving rod to swing.

[0015] A further improvement of the present invention is that the servo motor is electrically connected to a pedal control switch via a motor controller.

[0016] A vehicle comprises the flip cleaning step, wherein a chassis protection plate is connected below the mounting base, an avoidance groove is provided on the chassis protection plate, and the avoidance groove accommodates a movable connecting rod mechanism when the anti-slip pedal is in a retracted state.

[0017] It can be seen from the above technical scheme that the beneficial effects of the present invention are: one of the driving rods, under the drive of the motor, realizes the telescopic action of the movable link mechanism through the commonly connected anti-slip pedal; the locking assembly can be locked together with the movable link when the driving rod is in a retracted state, avoiding the jitter caused by the clearance between components and the accompanying abnormal noise problem.

Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0028] like Figure 1-7 As shown, a flip cleaning step comprises a mounting base 1, a movable link mechanism 2 and an anti-slip pedal 4, wherein the movable link mechanisms 2 are respectively provided at both ends of the mounting base 1, and the free ends of the two movable link mechanisms 2 are commonly connected to the anti-slip pedal 4; The installation base 1 includes a connecting plate 14, a connecting pipe 13, and a connecting base 11; both ends of the connecting plate 14 are respectively connected to the connecting base 11 through the connecting pipe 13, and the two connecting bases 11 are installed on a bearing member to support the connecting plate 14; both ends of the connecting plate 14 are respectively provided with the movable link mechanism 2 and the overall structure is in a U-shaped structure, which helps to improve the overall structural strength; the connecting pipe 13 is also provided with a bent section at an obtuse angle, which helps to improve the structural strength.

[0029] The movable link mechanism 2 includes a driving rod 22, a first movable link 23, and a second movable link 24.
