Description

Technical Field

[0001] This utility model relates to the field of performance testing technology for fitness equipment, specifically a foot pedal impact testing device for fitness equipment. Background Technology

[0002] The foot pedals of fitness equipment are core load-bearing and motion-transmitting components. Structural safety is a fundamental performance requirement for foot pedals, necessitating compliance with stringent standards such as load-bearing capacity, impact resistance, and anti-fall-off properties to prevent breakage, deformation, and other safety hazards during exercise. Therefore, it is necessary to test the impact resistance of the foot pedals. (See attached image) Figure 1 The diagram shows the structure of one of the posts in a common fitness equipment, the elliptical trainer, including its foot pedal structure. Currently, impact tests on the foot pedals typically involve setting up a support platform at a specified height, fixing the post to the support frame, and then pushing a weight of a specified amount from the upper surface of the platform onto the foot pedal to conduct the impact test.

[0003] The existing experimental setup has the following shortcomings:

[0004] 1. After the hammer hits the foot pedal, it will bounce off randomly, posing a certain safety hazard. Appropriate safety protection facilities need to be installed.

[0005] 2. When testing again, the hammer needs to be manually picked up and lifted onto the upper surface of the support platform, which is quite laborious.

[0006] 3. The position of the hammer landing on the foot pedal is unstable, which affects the accuracy and comparability of the test results. If the pushing technique is incorrect, the hammer may not even hit the foot pedal directly. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a foot pedal impact testing device for fitness equipment.

[0008] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is: a foot pedal impact testing device for fitness equipment, comprising:

[0009] Base;

[0010] A vertical support is fixedly installed on one side of the base;

[0011] A pile fixing mechanism is installed at the lower part of the vertical support, and the pile fixing mechanism is used to fix the pile of the fitness equipment being tested;

[0012] An upper horizontal support is fixedly installed on the upper part of the vertical support. The upper horizontal support is provided with a horizontally arranged slide rail assembly, which includes a slide rail and a slider movably installed on the slide rail.

[0013] The upper slide is mounted on the slider of the slide rail assembly;

[0014] A lifting frame, which is vertically and retractably installed through the upper sliding table;

[0015] A lifting drive mechanism is used to drive the lifting frame to move up and down relative to the upper slide table;

[0016] An impact hammer is mounted on the lifting frame in a height-adjustable manner, and the impact hammer is located below the upper slide table;

[0017] A weight lifting seat is mounted on the lifting frame in a height-adjustable manner, and the weight lifting seat is located between the upper slide and the impact weight;

[0018] A lifting mechanism is installed on the upper slide platform, and the lifting mechanism is used to drive the weight lifting seat to be lifted upward along the lifting frame;

[0019] A release mechanism is installed on the hammer lifting seat, and the release mechanism is used to control the connection and release between the impact hammer and the hammer lifting seat.

[0020] By employing the technical solution of this utility model, the impact hammer is mounted on a lifting frame in a height-adjustable manner, ensuring that the lifting and impact process of the hammer always follows the guide of the lifting frame. This effectively avoids the problem of the hammer falling irregularly after impact in traditional tests, significantly reducing safety hazards. With the cooperation of the lifting and releasing mechanisms, the impact hammer can be automatically lifted and precisely released, eliminating the need for manual picking up and carrying of the hammer to a designated height, significantly saving labor costs and improving test efficiency. At the same time, the horizontal position of the upper slide and the lifting frame can be adjusted through the slide rail assembly, and the vertical height of the lifting frame can be adjusted in conjunction with the lifting drive mechanism. This allows for precise control of the relative position of the impact hammer and the foot pedal, ensuring the consistency of the impact point for each test. This greatly improves the accuracy of test results and the comparability of different batches of tests, solving the problem of unstable impact point in traditional push-down methods.

[0021] Furthermore, the pile fixing mechanism includes a mounting panel and a circular clamp. The mounting panel is fixedly installed on the lower side of the vertical support. The circular clamp includes a first semicircular clamp ring and a second semicircular clamp ring. The first semicircular clamp ring is fixedly installed on the side of the mounting panel by bolts. A D-section is provided at the point where the first semicircular clamp ring abuts the mounting panel. The first semicircular clamp ring and the second semicircular clamp ring are detachably connected by a locking member.

[0022] The above-mentioned preferred scheme adopts a circular clamp structure design that is adapted to the structural characteristics of a circular pile. By splitting and combining the first and second semicircular clamps, it is convenient to quickly clamp and disassemble the pile, thereby improving the efficiency of test preparation. The D-section can increase the contact area between the first semicircular clamp and the mounting panel, ensuring the stability of the pile fixation.

[0023] Furthermore, it also includes a square clamp, which includes a base plate, a left side plate, a right side plate, and an outer pressure plate. The base plate is detachably connected to the open end face of the first semi-circular hoop by bolts. The left side plate and the right side plate are respectively vertically installed on the left and right sides of the base plate. The outer pressure plate is detachably connected to the ends of the left side plate and the right side plate by bolts.

[0024] By adopting the above-mentioned preferred scheme, the detachable connection structure of the square clamp and the round clamp allows the device to flexibly switch the fixing components according to the cross-sectional shape (round or square) of the pile being measured, without having to replace the entire pile fixing mechanism, which significantly improves the applicability of the device; the square clamp forms a stable square clamping space through the combination of the base plate, left and right side plates and the outer pressure plate, and can be firmly fixed to the square pile by locking with bolts.

[0025] Furthermore, a first oblique reinforcing connecting rod is provided between the lower part of the vertical support and the base, and a second oblique reinforcing connecting rod is provided between the top of the vertical support and the upper horizontal support.

[0026] By adopting the above-mentioned preferred scheme, the first oblique reinforcing connecting rod can enhance the structural strength of the connection between the vertical support and the base; the second oblique reinforcing connecting rod can improve the connection stability between the vertical support and the upper horizontal support, prevent the upper horizontal support from bending due to bearing the weight of the impact hammer and the test impact force, ensure the structural rigidity of the entire device, provide a stable support foundation for the accurate conduct of the test, and extend the service life of the device.

[0027] Furthermore, the lifting frame includes a top connecting plate, a bottom connecting plate, a first main column, and a second main column. The top ends of the first and second main columns are fixedly connected to the top connecting plate, and the bottom ends of the first and second main columns are fixedly connected to the bottom connecting plate. The first and second main columns are movably installed through the upper sliding table via guide sleeves.

[0028] Furthermore, the lifting drive mechanism includes a lifting platform mounting plate, a worm gear screw jack, and a motor. The lifting platform mounting plate is horizontally fixedly installed on one side of the upper surface of the upper slide. The worm gear screw jack is fixedly installed to the lifting platform mounting plate. The output shaft of the motor is connected to the input shaft of the worm gear screw jack via a coupling. The top end of the screw of the worm gear screw jack is connected to the top connecting plate of the lifting frame. Below the top connecting plate, there are also a first and a second auxiliary guide column extending vertically downward. The first and the second auxiliary guide columns are respectively movably installed through the lifting platform mounting plate via guide sleeves. The first and the second auxiliary guide columns are located on both sides of the screw of the worm gear screw jack.

[0029] By adopting the above-mentioned preferred solution, the worm gear screw jack has the characteristics of high transmission accuracy and good self-locking performance. With the motor drive, it can achieve precise lifting and lowering of the lifting frame, thereby accurately adjusting the bottom height of the lifting frame to adapt to the height position of the foot pedals of different fitness equipment. The auxiliary guide columns on both sides effectively prevent the lifting frame from deflecting or shaking during the lifting process, further improving the stability and accuracy of the lifting action and ensuring the consistency of the impact landing point.

[0030] Furthermore, the impact hammer includes a hammer block, an impact head, and an upper connecting head. The two ends of the hammer block are slidably mounted on the first and second main guide columns. The impact head is located below the hammer block and between the first and second main guide columns. The upper connecting head is located above the hammer block and has a first horizontal connecting hole. The bottom connecting plate of the lifting frame has a lower through hole for the impact head to pass through downward.

[0031] By adopting the above-mentioned preferred scheme, the sliding fit design between the hammer block and the main column ensures that the impact hammer always moves along the guide of the main column during the lifting and impact process, thus improving the safety of the test. The impact head is set between the two main columns, which can ensure that the impact head accurately acts on the designated position of the foot pedal and avoid impact deviation. The design of the lower through hole of the bottom connecting plate provides sufficient space for the impact action of the impact head, avoids the bottom connecting plate from interfering with the impact process, ensures that the impact energy is transferred to the foot pedal, and improves the accuracy of the test results.

[0032] Furthermore, the hammer lifting base includes a lifting base body and an upper connecting block. The two ends of the lifting base body are slidably mounted on the first and second main guide columns. The upper connecting block is located above the lifting base body. The lifting base body and the upper connecting block are provided with slots for the upper connector of the impact hammer to be inserted upwards. The upper connecting block is also provided with a second horizontal connecting hole. The release mechanism includes an angle seat, a linear actuator, and a connecting shaft. The angle seat is fixedly mounted on the lifting base body. The base of the linear actuator is horizontally mounted on the angle seat. The connecting shaft is connected to the telescopic rod of the linear actuator. The linear actuator is used to drive the connecting shaft to move axially along the second connecting hole. After the upper connector of the impact hammer is inserted into the slot of the upper connecting block, the connecting shaft is inserted into the first and second connecting holes to connect the impact hammer to the hammer lifting base.

[0033] By adopting the above-mentioned preferred scheme, the slot design enables the upper connector and the counterweight lifting seat to be quickly positioned and inserted, and the linear driver drives the connecting shaft to realize the automated control of the counterweight release, making the release action more precise and stable.

[0034] Furthermore, a proximity switch is installed on the lifting base. When the proximity switch abuts against the counterweight block, the first connecting hole of the upper connector and the second connecting hole of the upper connecting block are in a coaxial state.

[0035] Using the above-mentioned preferred scheme, the proximity switch can detect the relative position of the counterweight block and the lifting seat in real time. When the two come into contact, a signal is sent in time to indicate that the first and second connecting holes are in a coaxial state. At this time, the connecting shaft of the control release mechanism can be moved to achieve precise insertion and realize the automated positioning and detection of the docking process between the counterweight lifting seat and the impact counterweight.

[0036] Furthermore, the lifting mechanism includes a reduction motor, a take-up reel, a guide pulley, and a traction steel rope. The base of the reduction motor is fixedly installed on the upper slide platform. The take-up reel is fixedly connected to the output shaft end of the reduction motor. The guide pulley is rotatably installed on the upper slide platform via a bearing seat. One end of the traction steel rope is wound around the take-up reel, passes through the guide pulley, and then passes down through the upper slide platform to connect with the counterweight lifting seat.

[0037] By adopting the above-mentioned preferred scheme, the geared motor can provide a stable driving force, which, together with the rotation of the take-up reel, enables the winding and unwinding of the traction steel rope, thereby driving the lifting seat of the hammer to rise and fall, ensuring precise control of the lifting speed and lifting height, meeting the requirements of different test standards for the initial height of the impact hammer, and greatly improving test efficiency.
