Description

Technical Field

[0001] The invention belongs to the technical field of bicycle frame detection, and in particular relates to a simulated drop impact detection device for a bicycle frame front fork assembly. Background Art

[0002] As a widely used means of transportation and sports equipment, bicycles have received great attention for their safety. As the core structural components of bicycles, the strength and impact resistance of the frame and front fork are directly related to riding safety. Therefore, drop impact testing of the frame and front fork assembly is an important part of evaluating its safety.

[0003] Existing drop impact detection devices usually require the frame to be fixed to simulate the impact conditions that may be encountered in actual use. However, these devices have some shortcomings. First, when performing a drop test, the existing devices usually require the frame to be fixed together with the upper fixing device. This means that during the test, the fixing device will fall together with the frame, resulting in the inability to detect the drop impact of the empty frame alone. This test method cannot accurately simulate the impact of the frame under no load.

[0004] Secondly, existing test devices can usually only perform drop impact tests in a single direction or angle, which limits the comprehensiveness of the test. In actual use, bicycles may be impacted in many different directions and angles, so a test device that can simulate multiple drop angles and directions is essential for a comprehensive assessment of the safety of the frame.

[0005] Finally, existing test devices are often not flexible enough when adjusting the drop height and cannot meet different test standards and requirements. The difference in drop height directly affects the magnitude of the impact force and has poor applicability. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0024] Please see attached Figure 1-Figure 14As shown, this embodiment provides a simulated drop impact detection device for a bicycle frame front fork assembly, comprising a main body assembly 10, the main body assembly 10 comprising a chassis assembly 11, a vibration plate 12 is disposed on the chassis assembly 11, and a blocking assembly 13 is disposed on the chassis assembly 11; The test assembly 20 includes a lifting assembly 21 disposed on the chassis assembly 11, a separation assembly 22 is disposed at the bottom of the lifting assembly 21, a suspension assembly 23 is disposed on the lifting assembly 21, an additional assembly 24 is disposed on the chassis assembly 11, and a fixing assembly 25 is disposed below the chassis assembly 11; a frame 30 is disposed below the suspension assembly 23; Among them, after the frame 30 is connected to the suspension assembly 23, the lifting assembly 21 rises along the chassis assembly 11 to lift the frame 30 to a specified height, and the separation assembly 22 is used to release the connection of the lifting assembly 21, so that the frame 30 falls freely; The suspension assembly 23 is used to place the frame 30 at a suitable position, and the fixing assembly 25 is used to connect the frame 30 and the lifting assembly 21 together.

[0025] It should be noted that the vibration plate 12 is a device (not shown in the figure) connected to an external vibration motor, which is intended to use the vibration plate 12 to simulate a vibrating road surface to improve the accuracy and diversity of detection.

[0026] In this embodiment, after the frame 30 is installed on the suspension assembly 23 in a certain direction and angle according to the detection requirements, the lifting assembly 21 starts to work and smoothly lifts the frame 30 to a preset height. At this time, the separation assembly 22 and the mounting part of the lifting assembly 21 are in a locked state to ensure the stability and safety of the frame 30 during the lifting process. When the frame 30 reaches the predetermined position, the driving part of the separation assembly 22 is operated to separate it from the mounting part of the lifting assembly 21, and the frame 30 immediately enters a free fall state. At the same time, the vibration plate 12 is started to simulate a bumpy road surface at a certain frequency, so that the frame 30 experiences a variety of different impacts and vibrations during the falling process, thereby more comprehensively simulating the road conditions in actual riding.

[0027] Next, please refer to Figure 1-Figure 4 The chassis assembly 11 includes a base 111, a support 112 is movably sleeved below the base 111, a spring 113 is fixedly connected to the inner cavity of the support 112, the top of the spring 113 is fixedly connected to the bottom of the base 111, and support rods 114 are fixedly connected to the four corners of the top surface of the base 111, and a top plate 115 is fixedly connected to the top of the support rod 114; The blocking assembly 13 includes a connecting groove 131 opened on the support rod 114, the inner cavity of the connecting groove 131 is movably inserted with a blocking block 132, the front top of the blocking block 132 passes through the connecting groove 131 and is movably sleeved with a fastening block 133, the front contact of the fastening block 133 is connected with a nut 134, and the nut 134 is threadedly connected to the outer ring of the screw on the blocking block 132.

[0028] It should be noted that there are multiple groups of connecting grooves 131, so that the fastening blocks 133 can be connected to appropriate connecting grooves 131 according to the size and orientation of the frame 30, so that when the frame 30 falls, the lifting assembly 21 is stuck in a suitable position, so that the lifting assembly 21 does not contact the frame 30, and when the frame 30 contacts the vibration plate 12, the suspension assembly 23 does not pull the frame 30, so as to achieve the effect of the empty frame falling.

[0029] In this embodiment, the device will generate vibrations during testing, and the buffer structure composed of the movable sleeve support 112 and the spring 113 under the base 111 can effectively absorb these vibrations and maintain the stability and accuracy of the entire device. At the same time, the design of the support rod 114 and the top plate 115 not only provides a stable support, but also facilitates the installation and fixation of other components. The combination of the blocking block 132 and the fastening block 133 allows the device to be flexibly adjusted according to the size of the frame 30 and the test requirements. By connecting the blocking block 132 to different connecting grooves 131 through the nut 134 and the fastening block 133, it can be ensured that when the frame 30 is falling, the lifting assembly 21 will be blocked by the blocking block 132 so that it will not collide with the frame 30, thereby avoiding possible interference and damage.

[0030] Next, please refer to Figure 5-Figure 8 The lifting assembly 21 includes a lifting plate 211 slidably connected to the outer ring of the support rod 114, a hook 212 is fixedly connected to the top of the lifting plate 211, a lifting rod 213 is slidably connected to the top of the top plate 115, a pull rope 214 is fixedly connected to the bottom of the inner cavity of the lifting rod 213, a first motor 215 is fixedly connected to the right side of the top surface of the top plate 115, a wire drum 216 is fixedly connected to the output shaft of the first motor 215, the right end of the pull rope 214 is fixedly connected to the inner ring of the wire drum 216, a first roller group 217 is fixedly connected to the right side of the top surface of the top plate 115, and the middle outer ring of the pull rope 214 is rollingly connected to the inner ring of the first roller group 217; The disengagement assembly 22 includes a collar 221 fixedly connected to the bottom end of the lifting rod 213, a sliding ring 222 is slidably connected to the inner cavity of the collar 221, the sliding ring 222 is sleeved on the hook 212, a tooth groove 223 is provided in the middle of the inner ring of the sliding ring 222, a second motor 224 is fixedly connected to the rear side of the collar 221, a rotating rod 225 is fixedly connected to the output shaft of the second motor 224, the rotating rod 225 is rotatably connected to the top of the inner ring of the collar 221 through a pipe sleeve, a gear 226 is fixedly connected to the outer ring of the middle section of the rotating rod 225, and the outer ring of the gear 226 passes through the collar 221 and meshes in the tooth groove 223; The additional component 24 includes an additional rod 241 fixedly connected to the top surface of the landing plate 211, a scale bar 242 is opened on the outer circle of the support rod 114, and a perspective window 243 is opened in the area outside the scale bar 242 on the right side of the landing plate 211.

[0031] It should be noted that an empty slot is provided on the right side of the lifting and lowering rod 213 so that the pull rope 214 can smoothly pass through the lifting and lowering rod 213; An empty slot is formed at the top of the inner ring of the collar 221 , and the gear 226 meshes with the tooth groove 223 through the empty slot.

[0032] In this embodiment, after the vehicle frame 30 is installed on the suspension assembly 23, the first motor 215 is started, driving the wire drum 216 to rotate, so that the pull rope 214 begins to be wound on the wire drum 216, pulling the lifting rod 213 to slide upward along the track on the top plate 115. In this process, the lifting plate 211 rises synchronously on the outer ring of the support rod 114, thereby driving the vehicle frame 30 to gradually rise. Through the setting of the first roller group 217, the pull rope 214 can roll smoothly during the sliding process, reducing friction and improving the efficiency and stability of lifting. As the vehicle frame 30 gradually rises and reaches a predetermined height, the second motor 224 drives the rotating rod 225 to rotate, and the gear 226 also rotates accordingly. Since the gear 226 is meshed with the tooth groove 223 of the inner ring of the sliding ring 222, the sliding ring 222 begins to slide along the inner cavity of the ring 221 and finally detaches from the hook 212. This action releases the connection between the landing plate 211 and the collar 221, and the landing plate 211 and the frame 30 enter a free fall state. Before falling, a counterweight can be added to the additional rod 241 to meet different test requirements. At the same time, the design of the scale bar 242 and the perspective window 243 allows the user to clearly observe the height of the landing plate 211 to accurately control the lifting height of the frame 30.

[0033] Next, please refer to Figure 9-14The suspension assembly 23 includes a clamping ring 231 sleeved on the outer ring of the frame 30, a fastening bolt 232 is threadedly connected to the middle of the clamping ring 231, a steel wire rope 233 is fixedly connected to the top of the clamping ring 231, a second roller group 234 is fixedly connected to the top surface of the landing plate 211, the steel wire rope 233 is rollingly connected to the middle part of the second roller group 234, a winding rod 235 is fixedly connected to the top surface of the landing plate 211, the outer ring of the middle section of the steel wire rope 233 is wound around the outer ring of the winding rod 235, and the inner cavity of the winding rod 235 is slidably connected to the clamping plate 236 The middle part of the clamping plate 236 is threadedly connected with a first screw rod 237, the top of the first screw rod 237 is rotatably connected to the top of the winding rod 235, the top surface of the lifting and lowering plate 211 is fixedly connected with a positioning tube 238, the inner cavity of the positioning tube 238 is slidably connected with a positioning block 239, the middle part of the positioning block 239 is rotatably connected with a second screw rod 2310, the outer ring of the second screw rod 2310 is threadedly connected to the middle part of the positioning tube 238, the rear end of the wire rope 233 is fixedly connected with a magnetic block 2311, and the magnetic block 2311 is adsorbed on the lifting and lowering plate 211; The fixing assembly 25 includes a guide rail 251 fixedly connected to the bottom of the lifting plate 211, and arc plates 252 are slidably connected to the left and right sides of the inner cavity of the guide rail 251, and the top of the arc plate 252 is threadedly connected to a bidirectional screw rod 253, and the bidirectional screw rod 253 is rotatably connected to the inner cavity of the guide rail 251; The bidirectional screw rod 253, the first screw rod 237 and the second screw rod 2310 are all provided with a rotating handle; A magnetic adsorption plate is provided on the lifting plate 211, and the magnetic block 2311 is adsorbed on the magnetic adsorption plate to prevent the steel wire rope 233 from swinging around during the descent process, thereby affecting the accuracy of the detection.

[0034] It should be noted that the inner rings of the clamping ring 231 and the positioning block 239 are both provided with anti-slip pads, in order to improve the stability of clamping the frame 30 and the wire rope 233 .

[0035] In this embodiment, before testing, the clamping ring 231 is put on the appropriate position of the frame 30, and then the clamping ring 231 is fastened to the outer ring of the frame 30 by using the fastening bolt 232. Then, the steel wire rope 233 is pulled according to the placement requirements of the frame 30. By pulling the steel wire ropes 233 at the four corners, the frame 30 is adjusted to a suitable position and angle. When moving, the steel wire rope 233 passes through the middle of the second roller group 234 and is wound around the outer ring of the winding rod 235. By rotating the first screw rod 237, the clamping plate 236 slides downward along the inner cavity of the winding rod 235 until the clamping plate 236 clamps and fixes the middle section of the steel wire rope 233. At the same time, by rotating the second screw rod 2310, the positioning block 239 slides in the inner cavity of the positioning tube 238 until the steel wire rope 233 is clamped, and then the magnetic block 2311 contacts and adsorbs the magnetic adsorption plate on the landing plate 211 to ensure the stability of the steel wire rope 233 during the detection process. When the counterweight detection is required, the bidirectional screw rod 253 is rotated to make the two arc plates 252 slide inward at the same time on the left and right sides of the inner cavity of the guide rail 251 until the inner rings of the two arc plates 252 clamp and fix the vehicle frame 30. The vehicle frame 30 is connected to the landing plate 211.

[0036] The working principle of the present invention is as follows: before testing, the clamping ring 231 is put on the appropriate position of the frame 30, and then the clamping ring 231 is fastened to the outer ring of the frame 30 by the fastening bolt 232, and then the steel wire rope 233 is pulled according to the placement requirements of the frame 30. By pulling the steel wire ropes 233 at the four corners, the frame 30 is adjusted to a suitable position and angle. When moving, the steel wire rope 233 passes through the middle of the second roller group 234 and is wound around the outer ring of the winding rod 235. By rotating the first screw rod 237, the clamping plate 236 slides downward along the inner cavity of the winding rod 235 until the clamping plate 236 clamps and fixes the middle section of the steel wire rope 233. At the same time, by rotating the second screw rod 2310, the positioning block 239 slides in the inner cavity of the positioning tube 238 until the wire rope 233 is clamped, and then the magnetic suction block 2311 contacts and adsorbs the magnetic adsorption plate on the lifting and lowering plate 211 to ensure the stability of the wire rope 233 during the detection process. When the counterweight detection is required, the bidirectional screw rod 253 is rotated so that the two arc plates 252 slide inward on both sides of the inner cavity of the guide rail 251 at the same time until the inner rings of the two arc plates 252 clamp the frame 30. The frame 30 is connected to the lifting and lowering plate 211, and a counterweight can also be added to the additional rod 241 to meet different test requirements. Then the first motor 215 is started, driving the wire drum 216 to rotate, so that the pull rope 214 begins to be wound on the wire drum 216, pulling the lifting and lowering rod 213 to slide upward along the track on the top plate 115. The lifting and lowering plate 211 and the frame 30 are driven to rise. After reaching the predetermined height, the second motor 224 drives the rotating rod 225 to rotate, and the gear 226 also rotates accordingly. Since the gear 226 is meshed with the tooth groove 223 of the inner ring of the sliding ring 222, the sliding ring 222 begins to slide along the inner cavity of the collar 221, and finally disengages from the hook 212. This action releases the connection between the landing plate 211 and the collar 221, and the landing plate 211 and the frame 30 immediately enter a free fall state until they fall on the vibration plate 12 to complete the free fall impact test. At the same time, the vibration plate 12 can also simulate a bumpy road surface at a certain frequency according to needs, so that the frame 30 experiences a variety of different impacts and vibrations during the falling process. When an empty frame falling detection is required, the blocking block 132 is connected to different connecting slots 131 through the nut 134 and the fastening block 133. It can be ensured that when the frame 30 is falling, the lifting plate 211 will be blocked by the blocking block 132 so that it will not collide with the frame 30, and when the frame 30 contacts the vibration plate 12, the wire rope 233 will not pull the frame 30, thereby realizing the empty frame falling impact test of the frame 30, and the device will generate vibrations during the detection, and the buffer structure composed of the movable sleeve support 112 and the spring 113 under the base 111 can effectively absorb these vibrations and maintain the stability and accuracy of the entire device.

[0037] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
