[0027] The terms "first", "second", "third" and the like are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.
[0028] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.
[0029] See also Figure 1 As shown, the embodiment of the first aspect of the utility model provides an automobile brake pedal bracket, which is used to install the automobile brake pedal bracket connected to the automobile brake pedal on the front of the automobile, and includes a bottom plate 1 for fixed connection with the front, a first side plate 2 fixedly connected to one side of the bottom plate 1 for supporting the brake pedal, a second side plate 3 fixedly connected to the other side of the bottom plate 1 and parallel to the first side plate 2, and a connecting plate 4 fixedly connected between the first side plate 2 and the second side plate 3. It should be noted that the front here refers to the partition between the engine or motor compartment and the car body in the automobile body structure, which is connected to the floor and the front pillar, and is installed under the upper cover of the front to prevent the exhaust gas, high temperature and noise in the engine or motor compartment from entering the car body.
[0030] Generally, the brake pedal of the car is fixedly connected to the end of the brake pedal swing arm so that the driver can step on it. In this embodiment, in order to assemble the brake pedal swing arm, the bracket also includes a pivot 5 rotatably connected between the first side plate 2 and the second side plate 3. Figure 2 As shown, the pivot 5 is cylindrical. When the brake pedal swing arm is fixedly connected to the pivot 5, when the driver steps on the brake pedal, the brake pedal swing arm will rotate with the central axis of the pivot 5 as the rotation axis, thereby driving the vehicle brake booster system to brake the vehicle or release the brake.
[0031] In this embodiment, in order to limit the swing amplitude of the brake pedal swing arm, the bracket further includes a limit plate 6 fixedly connected to the top of the connecting plate 4, one end of which is fixedly connected to the connecting plate 4, and the other end is used to abut against the brake pedal swing arm. When the brake pedal swing arm rotates counterclockwise with the central axis of the pivot 5 as the rotation axis, the limit plate 6 abutting against the brake pedal swing arm is helpful to ensure that the brake pedal swing arm stays in the expected position or area.
[0032] See also Figure 2As shown, the bottom plate 1 includes a main body 11, a first mounting portion 12 arranged at one end of the main body 11, and a second mounting portion 13 arranged at the other end of the main body 11. It should be noted that, in consideration of adapting to the shape of the reinforcing bracket on the front of the automobile, in this embodiment, the main body 11 includes an upper top plate, a lower top plate and a middle top plate connected between the upper top plate and the lower top plate, wherein the angle between the upper top plate and the middle top plate, and the angle between the lower top plate and the middle top plate are both obtuse angles. When the main body 11 is connected to the reinforcing bracket on the front through surface contact, it is not only beneficial to store the reinforcing bracket on the front, strengthen the connection stability between the brake pedal bracket and the front, but also reduce the height of the brake pedal swing arm relative to the front in the direction perpendicular to the ground, thereby overcoming the problem that the bracket is easy to shake during implementation.
[0033] In this embodiment, in order to increase the connection surface area between the base plate 1 and the front enclosure, without being limited by the size of the main body 11 and to ensure the strength of the connection, the first mounting portion 12 extends in a direction away from the main body 11, and the second mounting portion 13 also extends in a direction away from the main body 11, and the extension direction of the first mounting portion 12 relative to the main body 11 is opposite to the extension direction of the second mounting portion 13 relative to the main body 11.
[0034] Furthermore, a first mounting hole 121 is formed at the top of the first mounting portion 12 and assembled with the front panel by means of fastening bolts, and a second mounting hole 131 is formed at the top of the second mounting portion 13 and assembled with the front panel by means of fastening bolts. In some embodiments, the number of the first mounting holes 121 and the number of the second mounting holes 131 can be multiple. In this embodiment, the number of the first mounting holes 121 is two, and the number of the second mounting holes 131 is four.
[0035] In this embodiment, in order to install the brake booster push rod of the automobile, the second mounting portion 13 is further provided with a third mounting hole 132, wherein the third mounting hole 132 and the second mounting hole 131 are coplanar with respect to the second mounting portion 13. It should be noted that the brake booster push rod mentioned here may refer to a brake booster or a part thereof, and is in transmission connection with the brake pedal swing arm. When the driver steps on the brake pedal, the brake pedal swing arm will rotate with the central axis of the pivot 5 as the rotation axis, and drive the brake booster push rod to work in conjunction, thereby braking the vehicle or releasing the brake.
[0036] In this embodiment, the first side panel 2 is roughly in the shape of a door-shaped plate, extending in a direction perpendicular to the ground, and includes a side panel body and an extension protruding from the middle of the side panel body. It should be noted that the extension of the first side panel 2 is in the shape of a semicircular arc, and a through hole for installing the pivot 5 is provided on the side so that the pivot 5 can be rotatably connected to the first side panel 2. For the purpose of weight reduction, preferably, the thickness of the first side panel 2 is 2.0 mm. The second side panel 3 is a symmetrical structure with the first side panel 2, which will not be described in detail here.
[0037] The connecting plate 4 is an S-shaped curved surface structure, which is arranged between the first side plate 2 and the second side plate 3, and fits with the top of the first side plate 2 and the second side plate 3, which not only improves the strength and rigidity of the bracket, but also provides an installation position for the limit plate 6. Through the displacement frequency response test, analysis and verification, when the connecting plate 4 is not set on the bracket, the modal value of the bracket before improvement is 266Hz, and the dynamic stiffness of the brake pedal swing arm installation point on the bracket is 651N / mm; when the bracket is improved, that is, the connecting plate 4 is set, the modal value of the bracket is 454Hz, and the dynamic stiffness of the brake pedal swing arm installation point on the bracket is 2246N / mm. It can be seen that under the action of the connecting plate 4, the ability of the bracket to resist deformation is improved, which can further prevent the occurrence of vibration mode out of control. It should be noted that the mode mentioned here is the natural vibration characteristic of the mechanical structure, and each order mode corresponds to a specific natural frequency, modal vibration shape and damping ratio. The modal vibration shape refers to the form of each order modal vibration. For example, the first-order mode appears when the excitation frequency of the external force is equal to the natural frequency of the object. At this time, the vibration form of the object is called the first-order vibration mode or the main vibration mode.
[0038] In some embodiments, in order to reduce the manufacturing cost and weight of the brake pedal bracket, the material thereof may be cast aluminum and may be made by hand or may be formed by an injection molding process.
[0039] An embodiment of the second aspect of the utility model provides a brake assembly, including a brake pedal of a vehicle and a vehicle brake pedal bracket as described in the above embodiment, wherein the brake pedal is hinged between a first side plate 2 and a second side plate 3 of the vehicle brake pedal bracket, so that the above brake assembly has the characteristics of better structural performance and is not easy to shake.
[0040] An embodiment of the third aspect of the utility model provides a car, comprising a front panel of the car and a brake assembly as described in the above embodiment, wherein the brake assembly is fixedly connected to the front panel, so that the above car has better NVH (noise, vibration and harshness) performance.
