Description

Technical Field

[0001] This application relates to the field of automotive component mounting technology, and more specifically, to an automotive component mounting bracket with a shock absorption function. Background Technology

[0002] Automotive parts assembly is one of the most important processes in automotive manufacturing. It involves assembling hundreds or thousands of qualified parts into a complete vehicle, engine, transmission, and other assemblies according to specific technical requirements. During assembly, the parts need to be fixed on mounting bases.

[0003] The patented CN213136654U discloses a mounting base for assembling automotive parts. When the bracket is subjected to force and sinks, the spring can absorb the pressure by contracting, share the force of the bracket, and ensure the shock absorption effect.

[0004] Although the patent can absorb pressure through spring contraction, the spring and the mounting base are fixedly connected in an inseparable manner. While this form can meet the basic load-bearing requirements, it is inconvenient to operate when the spring needs to be replaced due to fatigue failure and elasticity decay after long-term use. Utility Model Content

[0005] To address the aforementioned issues, this application provides a mounting bracket for automotive components with a shock absorption function.

[0006] The technical solution for a car component mounting bracket with buffer and shock absorption function provided in this application is as follows: A shock-absorbing mounting bracket for automotive components includes a mounting plate, a base plate disposed opposite to the mounting plate, and a shock-absorbing assembly disposed between the mounting plate and the base plate. The damping assembly includes multiple damping shock absorbers, each of which is detachably connected to the mounting plate and the base plate at both ends via a connector. A cushioning assembly for providing lateral buffering is also provided between the two base plates.

[0007] With the above technical solution, when the damping shock absorber is subjected to pressure, the piston rod contracts, the internal damping medium generates damping force to attenuate the impact energy, and the return spring drives the mounting plate to return to its original position after the pressure disappears. At the same time, multiple shock absorbers are evenly stressed, ensuring that the mounting plate is horizontal and preventing the components from shifting.

[0008] Furthermore, the buffer assembly includes two slide rods, each of which is fitted with a shock-absorbing spring.

[0009] Furthermore, the buffer assembly also includes two sets of connecting rods, and two sets of fixing plates are provided at both ends of the mounting plate and the shock-absorbing spring. Each set of fixing plates has a rotating shaft connected inside by fixing bolts.

[0010] With the above technical solution, if the mounting plate is subjected to lateral force during assembly, the connecting rod will drive the fixed plate to slide, compressing or stretching the shock-absorbing spring. The spring force of the shock-absorbing spring will counteract the lateral force, and the sliding rod will ensure that the fixed plate slides smoothly, avoiding the failure of the shock-absorbing spring.

[0011] Furthermore, each connecting rod is located between two corresponding rotating shafts and is rotatably connected to the corresponding rotating shafts.

[0012] Furthermore, circular plates are fixedly connected to both ends of the slide rod, and the circular plates are connected to the corresponding base plates by fixing bolts.

[0013] Furthermore, the top of the mounting plate is provided with a placement cylinder, and the bottom of the placement cylinder is fixedly connected to a connecting plate.

[0014] Furthermore, the mounting plate and the connecting plate are connected by fixing bolts.

[0015] In summary, this application includes at least one of the following beneficial technical effects: (1) When the damping shock absorber needs to be replaced due to fatigue failure of the internal reset spring, or the shock absorber spring of the buffer component needs to be maintained due to elastic decay after long-term use, there is no need to disassemble the entire structure of the mounting base. Only the corresponding fixing bolts need to be unscrewed with conventional tools to quickly remove the damping shock absorber or slide bar and shock absorber spring. After the replacement or maintenance is completed, the original position can be reinstalled by fixing bolts. The operation is convenient and time-saving. (2) By setting up the shock absorption components, when the damping shock absorber is subjected to pressure, the piston rod contracts and the internal damping medium generates damping force to attenuate the impact energy. The return spring drives the mounting plate to return to its original position after the pressure disappears. At the same time, multiple shock absorbers are evenly subjected to force to ensure that the mounting plate is horizontal and prevent the components from shifting. (3) If the mounting plate is subjected to lateral force during assembly, the connecting rod will drive the fixed plate to slide, compress or stretch the shock-absorbing spring, and the spring force of the shock-absorbing spring will counteract the lateral force. The sliding rod will ensure that the fixed plate slides smoothly and avoid the failure of the shock-absorbing spring. Attached Figure Description

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] Reference Figures 1-5 A shock-absorbing automotive component mounting base includes a mounting plate 1, a base plate 2 disposed opposite to the mounting plate 1, and a shock-absorbing component disposed between the mounting plate 1 and the base plate 2. The damping assembly includes multiple damping shock absorbers 5, and each damping shock absorber 5 is detachably connected to the mounting plate 1 and the base plate 2 at both ends via a connector 8. A buffer assembly for providing lateral cushioning is also provided between the two base plates 2.

[0020] After the components are placed, their own weight and the longitudinal impact force during assembly (such as hammering and pressing) will act on the mounting plate 1. At this time, multiple damping shock absorbers 5 between the mounting plate 1 and the base plate 2 will start to work: their two ends are detachably connected to the mounting plate 1 and the base plate 2 through connectors 8. When under pressure, the piston rod retracts, and the internal damping medium generates damping force to attenuate the impact energy. The return spring will drive the mounting plate 1 to return to its original position after the pressure is removed. At the same time, multiple shock absorbers are evenly stressed to ensure that the mounting plate 1 is horizontal and prevent the components from shifting.

[0021] The damping coefficient of the damping shock absorber 5 is usually 5000-20000 Ns / m (5000-12000 Ns / m for light load 5-15kg, and 12000-20000 Ns / m for heavy load 30-50kg), the relative damping ratio is controlled at 0.25-0.35, and the compression and extension damping forces are distributed at 1:2.5-1:4. At the same time, the dynamic load of a single shock absorber needs to be calculated to match the total load, ensuring that the ratio of the interference frequency of the components to the natural frequency of the shock absorber is >2, so as to avoid resonance. This value setting can ensure that the damping shock absorber 5 can both attenuate longitudinal impact and drive the mounting plate 1 to return smoothly, without vibration runaway or unstable rigid force transmission.

[0022] When the damping shock absorber 5 needs to be replaced, first unscrew the fixing bolts 13 of the connecting parts 8 at both ends of the shock absorber to the mounting plate 1 and the base plate 2, take out the entire damping shock absorber 5, replace it, and then align the replaced damping shock absorber 5 with the bolt holes and tighten it to fix it.

[0023] Reference Figures 3-5 The buffer assembly includes two slide rods 7, and shock-absorbing springs 11 are fitted on the outside of each slide rod 7. The buffer assembly also includes two sets of connecting rods 10. Two sets of fixing plates 6 are provided at both ends of the mounting plate 1 and the shock-absorbing springs 11. A rotating shaft 12 is connected to the inside of each fixing plate 6 by fixing bolts 13. Each connecting rod 10 is located between the corresponding two rotating shafts 12 and is rotatably connected to the corresponding rotating shaft 12. A circular plate 9 is fixedly connected to both ends of the slide rod 7. The circular plate 9 is connected to the corresponding base plate 2 by fixing bolts 13.

[0024] If the mounting plate 1 is subjected to a lateral force during assembly, the connecting rod 10 will drive the fixed plate 6 to slide, compressing or stretching the shock-absorbing spring 11. The spring force of the shock-absorbing spring 11 will counteract the lateral force in the opposite direction, while the sliding rod 7 will ensure that the fixed plate 6 slides smoothly and prevent the shock-absorbing spring 11 from failing.

[0025] When the shock absorber spring 11 needs to be replaced after long-term use, first unscrew the fixing bolts 13 on the circular plates 9 at both ends of the fixed slide rod 7 on the base plate 2, then unscrew the fixing bolts 13 on the rotating shaft 12 and take out the rotating shaft 12. At this time, the slide rod 7 and the shock absorber spring 11 can be removed. Then, push the fixing plate 6 along the slide rod 7 to make the shock absorber spring 11 separate from the contact surface, pull out the old shock absorber spring 11 and put on the new shock absorber spring 11, and then put the assembly back in its original position and tighten the fixing bolts 13.

[0026] Reference Figures 1-4 The top of the mounting plate 1 is provided with a placement cylinder 3, and the bottom of the placement cylinder 3 is fixedly connected to a connecting plate 4. The mounting plate 1 and the connecting plate 4 are connected by fixing bolts 13.

[0027] Before installation, the parts to be assembled (such as the motor rotor shaft) are placed in the placement cylinder 3 at the top of the mounting plate 1. The inner wall of the cylinder fits against the outer wall of the parts, constraining the parts circumferentially and preventing radial movement during assembly, thus providing a stable reference for subsequent operations. Because the placement cylinder 3 is rigidly connected to the mounting plate 1 by the bottom connecting plate 4 and the fixing bolts 13, when it is necessary to assemble different models of motor rotor shafts, the assembly of different models of motor rotor shafts can be carried out by replacing the appropriate placement cylinder 3.

[0028] Working principle: First, prepare for installation. If assembling different models of motor rotor shafts, first unscrew the fixing bolts 13 of the mounting plate 1 and the bottom connecting plate 4 of the placement cylinder 3, replace with a placement cylinder 3 that matches the inner diameter of the corresponding rotor shaft, then align the connecting plate 4 and the mounting plate 1 with the bolt holes and tighten the fixing bolts 13 to complete the fitting and adjustment of the placement cylinder 3. During installation, place the motor rotor shaft to be assembled into the placement cylinder 3 at the top of the mounting plate 1. The inner wall of the placement cylinder 3 fits against the outer wall of the rotor shaft, constraining the rotor shaft circumferentially and preventing radial movement during assembly, providing a stable reference for subsequent operations. After the components are placed, their own weight and the longitudinal impact force generated by hammering and pressing during assembly act on the mounting plate 1. At this time, multiple damping shock absorbers 5 between the mounting plate 1 and the base plate 2 start to work: the two ends of the damping shock absorber 5 are detachably connected to the mounting plate 1 and the base plate 2 through the connector 8. When under pressure, the piston rod retracts, and the internal damping medium generates damping force to attenuate the impact energy. When the pressure is removed, the return spring in the damping shock absorber 5 drives the mounting plate 1 to return to its original position, and multiple shock absorbers are evenly stressed to ensure that the mounting plate 1 is horizontal and prevent the rotor shaft from deviating.

[0029] During assembly, if the mounting plate 1 is subjected to a lateral force, it will cause the fixed plate 6 in the buffer assembly to slide through the two sets of connecting rods 10. When the fixed plate 6 slides, it compresses or stretches the shock-absorbing spring 11, and the shock-absorbing spring 11 generates a reverse elastic force to counteract the lateral force.

[0030] When components need maintenance or replacement, to replace the damping shock absorber 5, unscrew the fixing bolts 13 of the connector 8 to the mounting plate 1 and the base plate 2, remove the old shock absorber, install the new shock absorber, and tighten the bolts; to replace the shock absorber spring 11, unscrew the fixing bolts 13 of the circular plate 9 to the base plate 2, the rotating shaft 12 to the fixing plate 6, remove the sliding rod 7 and the shock absorber spring 11, push the fixing plate 6 to disengage the spring, replace the new spring, reset the assembly, and tighten the bolts.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
