Abstract
Description
Technical Field
[0001] This application relates to the field of bolt storage technology, and in particular to a hopper assembly with elastic cushioning for storing automotive bolts. Background Technology
[0002] A silo assembly with elastic cushioning for storing automotive bolts is designed to address the issues of classification and management of automotive bolts during storage, as well as impact damage. In the automotive manufacturing and assembly field, bolts are a critical standard fastener, and their protection during storage and transportation is of paramount importance.
[0003] Currently, most bolt storage silos used in workshops are rigid structures or have only a simple elastic pad at the bottom. This design means that the silo can only slightly mitigate vertical impacts and has almost no buffering capacity for the more frequent lateral swaying and collisions during handling and transportation. This leads to violent collisions between bolts and between bolts and the silo, which can easily cause thread damage, head scratches, or bolt deformation, directly affecting assembly quality and product reliability. Utility Model Content
[0004] To address the issue of silos lacking buffering capacity, this application provides a silo assembly with elastic buffering for storing automotive bolts.
[0005] The present application provides a hopper assembly with elastic cushioning for storing automotive bolts, which adopts the following technical solution:
[0006] A hopper assembly with elastic cushioning for storing automotive bolts includes a frame with a plurality of hoppers disposed on the frame. The hoppers are equipped with a cushioning mechanism for cushioning the bolts. An inner frame is disposed inside the hoppers via the cushioning mechanism, and a connecting plate is fixedly disposed between the inner frame and the hoppers.
[0007] By adopting the above technical solution, the frame and multiple compartments constitute the main frame of the component. The internal buffer mechanism drives the inner frame to float elastically relative to the compartments through the connecting plate, thereby achieving multi-dimensional buffer protection for the storage bolts.
[0008] Preferably, the buffer mechanism includes several connecting devices 1 arranged around the inner frame for horizontal buffering of the inner frame, and the buffer mechanism also includes several connecting devices 2 arranged at the bottom of the inner frame for vertical buffering of the inner frame.
[0009] By adopting the above technical solution, connecting device one is responsible for absorbing the impact energy in the horizontal direction, while connecting device two is responsible for absorbing the impact energy in the vertical direction. Together, they form a composite buffer system that works in concert and can cope with complex impacts.
[0010] Preferably, the connecting device includes a fixed seat fixedly disposed on the inner wall of the compartment, a connecting seat rotatably disposed on one side of the fixed seat, a moving device for realizing horizontal movement of the inner frame disposed on one side of the connecting seat, a connecting seat 2 fixedly disposed at the moving end of the moving device, and a fixed seat 2 rotatably disposed on one side of the connecting seat 2 and fixedly disposed on the outer surface of the inner frame.
[0011] By adopting the above technical solution, the first fixed seat, the first connecting seat, the second fixed seat, and the second connecting seat constitute a rotatable connection end point, enabling the middle moving device to adapt to the horizontal displacement of the inner frame and convert the impact force into its internal compression motion.
[0012] Preferably, the moving device includes a fixed cylinder fixedly disposed on one side of the connecting seat, a movable column fixedly disposed inside the fixed cylinder and fixedly disposed with the connecting seat, and a return spring fixedly disposed between the connecting seat and the connecting seat and the connecting seat and the outer surface of the fixed cylinder and the movable column.
[0013] By adopting the above technical solution, the sliding cooperation between the fixed cylinder and the moving column ensures the guiding accuracy of the horizontal movement, while the return spring provides a restoring force after the horizontal impact force disappears, so that the inner frame automatically returns to the center position.
[0014] Preferably, the second connecting device includes a first fixing plate fixedly disposed at the bottom of the inner frame, a connecting cylinder fixedly disposed inside the first fixing plate, a compression device for longitudinally compressing the inner frame disposed on the outer surface of the connecting cylinder, a second fixing plate fixedly disposed inside the compartment, and a guide device for guiding the inner frame to move longitudinally disposed symmetrically between the first fixing plate and the second fixing plate.
[0015] By adopting the above technical solution, the first fixed plate and the connecting cylinder serve as the installation base of the compression device, and together with the second fixed plate, they form a support structure for vertical buffering. The guiding device in between ensures that the inner frame remains stable and does not tilt during the vertical buffering process.
[0016] Preferably, the compression device includes a ring symmetrically slidably disposed on the outer surface of the connecting cylinder, a second return spring fixedly disposed on the opposite side of the ring and sleeved on the outer surface of the connecting cylinder, and a connecting rod rotatably disposed on the outer surface of the ring and rotatably disposed with the second fixed plate.
[0017] By adopting the above technical solution, the two rings slide towards or away from each other on the connecting cylinder, storing and releasing energy by squeezing or releasing the second return spring. At the same time, the connecting rod converts the vertical movement of the inner frame into compression of the second return spring, achieving efficient vertical buffering.
[0018] Preferably, the guiding device includes a guide cylinder fixed to the top surface of the second fixed plate, a guide post fixedly disposed inside the guide cylinder and fixed to the first fixed plate, a return spring three sleeved between the first fixed plate and the second fixed plate, and a damper one fixed between the first fixed plate and the second fixed plate.
[0019] By adopting the above technical solution, the sliding fit between the guide post and the guide cylinder ensures the linearity and stability of the vertical movement of the inner frame. The return spring three provides the main vertical buffer and return force, while the damper one is used to quickly dissipate the impact energy and suppress the up-and-down reciprocating vibration.
[0020] Preferably, a plurality of dampers are fixed between the hopper body and the inner frame.
[0021] By adopting the above technical solution, the second damper, as an important supplement to the main buffer system, is directly installed between the chamber and the inner frame to further attenuate and suppress residual vibrations in all directions, thereby improving the stability of the entire buffer system.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By utilizing the rotation of connecting seats one and two, and the sliding of fixed cylinder one and moving column one, the entire inner frame can be displaced and deflected in the horizontal direction. Through the design of the damper, it absorbs lateral impacts from all directions. Return spring one is responsible for pulling the inner frame back to the center position. In the vertical direction, through the buffer mechanism composed of fixed plate one, connecting cylinder, ring, return spring two, connecting rod, fixed plate two, damper, guide cylinder, guide column and return spring three, when the inner frame is subjected to vertical impact force, the connecting rod rotates and drives the ring to slide on the connecting cylinder, return spring two and return spring three deform, and at the same time the damper consumes energy, further enhancing the buffering effect and protecting the automotive bolts in all directions.

[0033] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0034] This application discloses a hopper assembly with elastic cushioning for storing automotive bolts.
[0035] Reference Figures 1-3 A hopper assembly with elastic cushioning for storing automotive bolts includes a frame 1. A caster wheel, brand DMK-601, is fixed to the bottom of the frame 1 and features an insert-type brake design. Several hoppers 2 are placed on the frame 1. A cushioning mechanism 5 is installed inside each hopper 2 to cushion the bolts. An inner frame 3 is installed inside each hopper 2 via the cushioning mechanism 5. The outer surface of the inner frame 3 is fixedly connected to a connecting plate 4, and the other side of the connecting plate 4 is fixedly connected to the inner wall of the hopper 2. The connecting plate 4 is made of a flexible, extendable material.
[0036] When the frame 1 moves and causes vibration, the impact force is transmitted to the buffer mechanism 5 through the frame 1 and the chamber 2. The buffer mechanism 5 then starts to work, driving or allowing the inner frame 3 to convert the impact kinetic energy into elastic potential energy and heat energy during the relative displacement with the chamber 2 through the connecting plate 4, thereby protecting the bolts placed in the inner frame 3 from rigid collisions and achieving buffer protection.
[0037] Reference Figure 3 , Figure 4The buffer mechanism 5 includes several connecting devices 1, which are disposed between the outer surface of the inner frame 3 and the inner wall of the chamber 2. Several dampers 2 518 are fixedly connected between the chamber 2 and the inner frame 3. The connecting devices 1 are used to provide horizontal buffering for the inner frame 3. The connecting devices 1 include a fixed seat 1 51, which is fixedly connected to the inner wall of the chamber 2. A connecting seat 1 52 is rotatably connected to one side of the fixed seat 1 51. The connecting seat 1 52 is located on the side away from the chamber 2. A moving device is provided on one side of the connecting seat 1 52. The moving device is used to realize the horizontal movement of the inner frame 3. A connecting seat 2 55 is fixedly provided at the moving end of the moving device. A connecting seat 2 55 is rotatably connected to one side of the connecting seat 2 55. There is a fixed base 56, which is fixedly connected to the outer surface of the inner frame 3. The moving device includes a fixed cylinder 53, which is fixedly connected to one side of the connecting base 52. The fixed cylinder 53 is located on the side away from the fixed base 51. A moving column 54 is slidably connected to the inner wall of the fixed cylinder 53. The moving column 54 is fixedly connected to the connecting base 55, and the moving column 54 is located on the side away from the fixed base 56. A return spring 57 is fixedly connected to one side of the connecting base 52. The return spring 57 is fixedly connected to the connecting base 55 on the side away from the connecting base 52, and the return spring 57 is sleeved on the outer surface of the fixed cylinder 53 and the moving column 54.
[0038] When the inner frame 3 is subjected to a horizontal impact, the force is transmitted to the connecting seat 55 through the fixed seat 2 56, pushing the entire moving device to move in the direction of the connecting seat 1 52. Since the connecting seat 1 52 and the connecting seat 2 55 are both rotatably connected, they can adaptively adjust their angles to ensure that the moving device is subjected to axial compression or tension, avoiding structural jamming and allowing the horizontal buffering process to proceed smoothly. During the horizontal buffering process, the moving column 1 54 slides inside the fixed cylinder 1 53. This is a precise guiding process that prevents unnecessary deflection of the inner frame 3 during horizontal movement. At the same time, the return spring 1 57 and the damper 2 518 are compressed or stretched to store the impact energy. When the impact force disappears, the return spring 1 57 releases its energy, pushing the moving column 1 54 back to its original position, thereby driving the inner frame 3 to return to its initial position.
[0039] Reference Figure 3 , Figure 5The buffer mechanism 5 also includes several connecting devices 2. The connecting devices 2 are located at the bottom of the inner frame 3. The connecting devices 2 are used to provide longitudinal buffering for the inner frame 3. The connecting devices 2 include a fixing plate 1 58, which is fixedly connected to the bottom of the inner frame 3. A connecting cylinder 59 is fixedly connected to the inner wall of the fixing plate 1 58. A compression device is provided on the outer surface of the connecting cylinder 59. The compression device is used to provide longitudinal compression for the inner frame 3. A fixing plate 2 513 is fixedly connected to the bottom surface of the inner wall of the compartment 2. The compression device includes a ring 510, which is symmetrically slidably connected to the outer surface of the connecting cylinder 59. A return spring 2 511 is fixedly connected to the opposite surfaces of the two rings 510. The return spring 2 511 is sleeved on the outer surface of the connecting cylinder 59. A connecting rod 512 is rotatably connected to the outer surface of the ring 510. The connecting rod 512 is away from the outer surface. One side of the ring 510 is rotatably connected to the top surface of the fixing plate 2 513.
[0040] A guide device is symmetrically arranged between the first fixed plate 58 and the second fixed plate 513. The guide device is used to guide the inner frame 3 to move longitudinally. The guide device includes a guide cylinder 516, which is fixedly connected to the top surface of the second fixed plate 513. A guide post 515 is slidably connected inside the guide cylinder 516. The side of the guide post 515 away from the guide cylinder 516 is fixedly connected to the bottom surface of the first fixed plate 58. A return spring 517 is fixedly connected to the bottom surface of the first fixed plate 58. The side of the return spring 517 away from the first fixed plate 58 is fixedly connected to the second fixed plate 513. The return spring 517 is sleeved on the outer surface of the guide post 515 and the guide cylinder 516. A damper 514 is fixedly connected between the first fixed plate 58 and the second fixed plate 513.
[0041] When the inner frame 3 is subjected to a vertical downward impact, the fixing plate 58 moves inward and downward. The fixing plate 58 forces the two rings 510 to slide towards each other through the connecting cylinder 59, thereby strongly compressing the return spring 511 between them. At the same time, the connecting rod 512 rotates, converting the vertical linear displacement into stable compression of the return spring 511. Thus, the impact force can be efficiently and smoothly converted into the elastic potential energy of the spring.
[0042] Furthermore, during vertical movement, the guide post 515 slides stably within the guide cylinder 516, ensuring the guidance of the movement. The return spring 517 is compressed as the guide post 515 goes deeper, providing strong buffering force and storing energy. The damper 514 connected in parallel with it acts rapidly during this process. Its internal damping medium generates huge resistance, converting the impact kinetic energy into heat energy and dissipating it, thereby significantly suppressing the reciprocating bounce of the inner frame 3 in the vertical direction, enabling it to quickly return to stability.
[0043] Among them, damper 1 514 and damper 2 518 are both TaylorDevices dampers.
[0044] In this device, the return springs 1 (57), 2 (511), and 3 (517) all use the alloy spring calculation formula: F = kx, where F is the external force on the spring (unit: N / m), k is the spring constant (unit: N / m), and x is the spring deformation (unit: m). This formula is used to calculate the elastic force of the alloy springs so that they can be used in this device. All three return springs (57), 2 (511), and 3 (517) are made of 60Si2MnA high-grade spring steel, which has excellent elastic recovery properties.
[0045] The ring 510 is made of SUS304 stainless steel, the connecting rod 512 is made of high-strength aluminum alloy, ensuring that the structure is lightweight and has a strong load-bearing capacity, and the moving column 54 and the connecting column 59 are made of 40Cr alloy structural steel.
[0046] The connecting plate 4 is a telescopic cover made of corrugated rubber (EPDM) or multi-fold industrial coated canvas. Its outer edge is sealed to the top edge of the compartment 2 by pressure strip bolts, and its inner edge is sealed to the top edge of the inner frame 3.
[0047] The vertical buffer mechanism used in this invention has nonlinear variable stiffness characteristics. Both the first connecting seat 52 and the second connecting seat 55 in the first connecting device are designed as universal hinge structures with at least two rotational degrees of freedom.
[0048] The implementation principle of a hopper assembly with elastic cushioning for storing automotive bolts according to an embodiment of this application is as follows:
[0049] When the frame 1 vibrates during movement, the inner frame 3 will be subjected to horizontal impact. The force is transmitted to the connecting seat 55 through the fixed seat 56. Since the connecting seat 52 and the connecting seat 55 are both rotatable connections, they can adaptively adjust their angles to ensure that the moving device is subjected to axial compression or tension. During the horizontal buffering process, the moving column 54 slides in the fixed cylinder 53 to prevent unnecessary deflection of the inner frame 3 during horizontal movement. At the same time, the return spring 57 and the damper 518 are compressed or stretched to store the impact energy. When the impact force disappears, the return spring 57 releases the energy and drives the inner frame 3 to return to the initial position.
[0050] When the inner frame 3 is subjected to a vertical downward impact, the fixing plate 58 and the connecting cylinder 59 move downward, thereby causing the two rings 510 to slide towards each other, thus squeezing the second return spring 511. At the same time, the connecting rod 512 rotates, converting the vertical linear displacement into stable compression of the second return spring 511, thereby efficiently and smoothly converting the impact force into the elastic potential energy of the spring.
[0051] Furthermore, during vertical movement, the guide post 515 slides stably within the guide cylinder 516, ensuring the guidance of the movement. The return spring 517 is compressed as the guide post 515 goes deeper, providing strong buffering force and storing energy. The damper 514 connected in parallel with it acts rapidly during this process. Its internal damping medium generates huge resistance, converting the impact kinetic energy into heat energy and dissipating it, thereby significantly suppressing the reciprocating bounce of the inner frame 3 in the vertical direction, enabling it to quickly return to stability.
[0052] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
