Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, in particular to an anti-intrusion brake pedal. Background Art

[0002] The brake pedal is the operating unit for braking a car. When braking a car, force is applied to the push rod of the vacuum booster by stepping on the pedal. The push rod pushes the master cylinder to generate high pressure and thus braking force. When a car collides head-on or offsets, the cabin is severely deformed, and the brake pedal connected to it moves backward synchronously, causing injuries to the driver's legs. In order to avoid this injury, the driver's legs are protected when the car collides seriously. The existing technical solution is to set a structure to reduce pedal intrusion at the cantilever to reduce the amount of intrusion of the brake pedal. However, this solution is limited by the structure of the cantilever beam, resulting in the currently used anti-intrusion brake pedal having a bulky structure, a large material requirement, and a high cost. Summary of the invention

[0003] The purpose of the present invention is to provide an anti-intrusion brake pedal, which can effectively reduce the intrusion amount of the brake pedal by changing the connection structure between the brake pedal and the cabin, and has a streamlined structure, which is conducive to reducing costs.

[0004] The present invention provides an anti-intrusion brake pedal, including an anti-intrusion component and a pedal arm. The anti-intrusion component includes a connecting seat, a collision bracket and a collision lever. The connecting seat is fixedly connected to the front panel. The collision bracket is fixedly connected to the instrument tube beam. The collision lever is rotatably connected to the connecting seat and can rotate between a collision position and a safety position relative to the connecting seat. The collision lever has a first end and a second end. When the connecting seat moves toward the collision bracket, the collision bracket pushes the first end to rotate the collision lever from the safety position to the collision position. The pedal arm is hinged to the second end and is detachably connected to the connecting seat. When the collision lever rotates from the safety position to the collision position, the pedal arm is detached from the connecting seat under the push of the collision lever.

[0005] The anti-intrusion brake pedal provided by the present invention prevents the intrusion of a collision lever by means of a collision bracket fixedly connected to an instrument tube beam, and at the same time utilizes the rotation of the collision lever to drive the pedal arm to fall off from a state connected to the cabin, thereby reducing the intrusion amount of the brake pedal, simplifying the structure, and helping to reduce costs.

[0006] In another exemplary embodiment of the anti-intrusion brake pedal, a pin hole and a slot hole open at one end are provided on the top of the connection seat along a first direction. The anti-intrusion assembly includes a first pin shaft and a second pin shaft. The first pin shaft is inserted through the middle of the collision lever and plugged into the pin hole so that the collision lever rotates around the first pin shaft. The second pin shaft is inserted through the second end and is movably placed in the slot hole.

[0007] In another exemplary embodiment of the anti-intrusion brake pedal, a second pin is disposed through the pedal arm, and the pedal arm is driven by the collision lever to separate from the connection seat through the second pin.

[0008] In another exemplary embodiment of the anti-intrusion brake pedal, the anti-intrusion assembly includes a pair of fastening nuts, each of which is respectively connected to two ends of the second pin shaft and abuts against the connecting seat to prevent the second pin shaft from moving along the first direction.

[0009] In another exemplary embodiment of the anti-intrusion brake pedal, the anti-intrusion brake pedal further includes a booster push rod and a hydraulic unit. The hydraulic unit is fixedly connected to the connecting seat. The booster push rod is telescopically connected to the hydraulic unit and is hinged to the pedal arm.

[0010] In another exemplary embodiment of the anti-intrusion brake pedal, the collision bracket is L-shaped along the first direction. An end of the collision bracket along the first direction is connected to the instrument tube beam.

[0011] In another exemplary embodiment of the anti-intrusion brake pedal, the collision lever is V-shaped along the first direction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0019] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0020] Figure 1 FIG. 1 is a schematic diagram of a schematic implementation of an anti-intrusion brake pedal. Figure 1 As shown, the anti-intrusion brake pedal includes an anti-intrusion component 10 and a pedal arm 20. The anti-intrusion component 10 includes a connecting seat 12, a collision bracket 14 and a collision lever 16. The connecting seat 12 is fixedly connected to the front panel 50 so that when the car collides, the front panel 50 drives the connecting seat 12 to move toward the driver. The collision bracket 14 is welded to the instrument tube beam 60 to ensure that when the car collides, the collision bracket 14 can prevent the collision lever 16 from continuing to move toward the driver and provide a rotational force for the collision lever 16. Figure 1 As shown, in this exemplary embodiment, only when the front panel 50 of the automobile is deformed and invades the interior of the vehicle body during a collision, the collision bracket 14 contacts the collision lever 16 and triggers the collision lever 16 to rotate. In this exemplary embodiment, the collision bracket 14 is L-shaped along the first direction D1, but is not limited thereto. The end of the collision bracket 14 along the first direction D1 is fixedly connected to the instrument tube beam 60, thereby increasing the contact area with the collision lever 16 to ensure the stability of the anti-intrusion component.

[0021] Figure 2 It is a schematic diagram of the structure in which the anti-intrusion brake pedal is in a safe position. Figure 3 This is a schematic diagram of the structure of the anti-intrusion brake pedal in the collision position. Figure 2 and Figure 3As shown, the collision lever 16 is rotatably connected to the connection seat 12 and can rotate between the collision position and the safety position relative to the connection seat 12. When the collision lever 16 is in the safety position, a gap is left between the collision lever 16 and the collision bracket 14 to ensure that the collision bracket 14 and the collision lever 16 are independent of each other and do not affect each other during normal working conditions and daily driving of the car; when the collision lever 16 rotates to the collision position, the collision lever 16 contacts the collision bracket 14 and triggers the collision lever 16 to rotate. In this exemplary embodiment, the collision lever 16 is a V-shaped structure, and the collision lever 16 is inclined in the first direction D1. V-shaped, but not limited to this. The collision lever 16 has a first end 162 and a second end 164. When the connection seat 12 moves toward the collision bracket 14, the collision bracket 14 pushes the first end 162 to make the collision lever 16 rotate from the safety position to the collision position in the clockwise direction.

[0022] like Figure 2 and Figure 3 As shown, the pedal arm 20 is hingedly connected to the second end 164 and is detachably connected to the connecting seat 12. When the collision lever 16 is located at the safe position, the pedal arm 20 is connected to the connecting seat 12 so that the pedal arm 20 can operate normally; when the collision lever 16 rotates from the safe position to the collision position, the pedal arm 20 rotates and detaches from the connecting seat 12 via the collision lever 16 to ensure the safety of the driver.

[0023] Figure 4 is a schematic structural diagram of a schematic implementation of a connecting socket. Figure 4 As shown, the top of the connection seat 12 is provided with a through pin hole 121 and a slot hole 123 opened at one end along the first direction D1. Figures 2 to 4 As shown, the anti-intrusion assembly 10 includes a first pin shaft 11 and a second pin shaft 13. The first pin shaft 11 is inserted into the middle of the collision lever 16 and inserted into the pin hole 121 so that the collision lever 16 rotates around the first pin shaft 11. The second pin shaft 13 is inserted into the second end portion 164 and is movably placed in the slot 123. The second pin shaft 13 is inserted into the pedal arm 20, and the pedal arm 20 is driven by the collision lever 16 to detach from the connecting seat 12 through the second pin shaft 13. The structure is simple, and it is easy to maintain later, which effectively reduces the cost.

[0024] like Figure 1 As shown, the anti-intrusion brake pedal further includes a booster push rod 30 and a hydraulic unit 40, the hydraulic unit 40 is fixedly connected to the connection seat 12, and the booster push rod 30 is telescopically connected to the hydraulic unit 40 and is hinged to the pedal arm 20. Figure 2As shown, when the automobile is in a normal working condition, the first pin shaft 11 fixes the collision lever 16 and the connecting seat 12, and ensures that the connecting seat 12 and the collision lever 16 are fixed in relative position, and the pedal arm 20 can rotate relative to the connecting seat 12 and the collision lever 16 with the second pin shaft 13 placed in the slot 123 as the center, and the booster push rod 30 and the hydraulic unit 40 are used to achieve the braking function. In this exemplary embodiment, the anti-intrusion assembly 10 includes a pair of fastening nuts 15. The two fastening nuts 15 are respectively connected to the two ends of the second pin shaft 13 and abut the connecting seat 12 to prevent the second pin shaft 13 from sliding along the first direction D1, causing the second pin shaft 13 to fall off from the connecting seat 12, thereby ensuring that the pedal arm 20 can stably achieve the braking function.

[0025] like Figure 3 As shown, when the car collides, the front panel 50 of the car drives the connecting seat 12 and the collision lever 16 to move toward the collision bracket 14. The collision bracket 14 contacts the collision lever 16, and the first end 162 is pushed by the collision bracket 14, so that the collision lever 16 rotates clockwise with the second pin shaft 13 as the axis, so that the second end 164 drives the first pin shaft 11 to disengage from the slot 123, and then the pedal arm 20 is disconnected from the connection seat 12. In addition, the booster push rod 30 is hinged with the pedal arm 20. Under the action of the booster push rod 30, the pedal arm 20 rotates with the booster push rod 30 and its hinge point as the center of rotation, so that the lower end of the pedal arm 20 rotates toward the front of the vehicle body, thereby reducing the intrusion into the foot and reducing the damage to the driver. In this exemplary embodiment, the booster push rod 30 is made of plastic material, and does not affect the pedal arm 20 from falling off from the connecting seat 12 when a collision occurs. In addition, the anti-intrusion component provided by the present invention has a simple structure and can effectively reduce the weight of the car while protecting the driver, which is conducive to the development of lightweight cars.
