Description

Technical Field

[0001] The present application relates to the technical field of treadmills, and in particular to a treadmill pedometer. Background Art

[0002] The statements in this section merely provide background technical information related to this application and do not necessarily constitute prior art.

[0003] Methods for detecting the number of steps on a treadmill include using an acceleration sensor or detecting the movement distance of a motion component. Among them, calculating the number of steps using infrared blocking is a relatively simple and reliable detection method.

[0004] For example, the treadmill counter disclosed in utility model patent CN 221309447 U calculates the number of steps by using the number of infrared blocking times. However, this pedometer still has some problems. For example, the user's position on the running board is inconsistent, resulting in inconsistent vibration displacement transmitted to the movable rod, which can easily misidentify normal running as invalid vibration and cause incorrect step counting. At the same time, the large number of infrared beam sensors used increases manufacturing costs. Summary of the Invention

[0005] In order to solve the problems in the background technology, the present application proposes a treadmill pedometer.

[0006] The present application provides a treadmill pedometer, comprising a mounting shell, a limiting boss being provided on the top of the mounting shell, a detection slide groove being provided on the limiting boss and penetrating to the interior of the mounting shell, a detection rod being slidably provided in the detection slide groove, a limiting block being provided on the top of the detection rod, a reset spring being sleeved on the outer periphery of the detection rod, one end of the reset spring being connected to the bottom of the limiting block, and the other end being connected to the top of the mounting shell, an extension cross bar being provided on the top of the limiting block, and a plurality of detection contacts being arranged along the extension direction of the extension cross bar; a PCB transmitting board and a PCB receiving board being symmetrically provided on the inner wall of the detection slide groove, a plurality of opposing infrared sensors being symmetrically provided on the PCB transmitting board and the PCB receiving board from top to bottom, and a CPU controller being provided inside the mounting shell and electrically connected to the PCB transmitting board and the PCB receiving board.

[0011] Preferably, the detection contacts are evenly distributed along the extension direction of the extension cross bar.

[0012] Preferably, an elastic member is provided on the top of the detection contact.

[0013] Preferably, a fixing groove is provided at the bottom of the side wall of the mounting shell, and a fixing hole is provided at the bottom of the fixing groove.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) The present application sets an extension cross bar on the top of the detection rod and sets a plurality of detection contacts on the extension cross bar, so that the maximum vibration stroke at each position of the running board can be detected, thereby eliminating the problem of large differences in the vibration stroke of the detection position caused by the user running at different positions of the running board, and the step counting is more accurate.

[0016] (2) The bottom of the detection rod of the present application is embedded with an electric telescopic rod, which can conveniently adjust the extension position of the bottom end of the detection rod, so as to adjust the extension position of the bottom end of the detection rod according to the different weights of the users, thereby adjusting the sensitivity of the vibration stroke detection, which is beneficial to reducing the number of through-beam infrared sensors.

[0022] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Example 1

[0026] like Figures 1 to 2 As shown, the present application provides a treadmill pedometer, including a mounting shell 1, a limiting boss 2 is provided on the top of the mounting shell 1, a detection slide 21 is provided on the limiting boss 2 and passes through the interior of the mounting shell 1, a detection rod 3 is slidably provided in the detection slide 21, a limiting block is provided on the top of the detection rod 3, a reset spring 4 is sleeved on the outer periphery of the detection rod 3, one end of the reset spring 4 is connected to the bottom of the limiting block, and the other end is connected to the top of the mounting shell 1, an extension cross bar 5 is provided on the top of the limiting block, and a plurality of detection contacts 51 are arranged along the extension direction of the extension cross bar 5, a PCB transmitting board 6 and a PCB receiving board 7 are symmetrically provided on the inner wall of the detection slide 21, a plurality of opposing infrared sensors are symmetrically provided on the PCB transmitting board 6 and the PCB receiving board 7 from top to bottom, and a CPU controller electrically connected to the PCB transmitting board 6 and the PCB receiving board 7 is provided inside the mounting shell 1.

[0027] This application is set under the running board of the treadmill, and the detection contact 51 is in contact with the running board. When the user runs, the running board vibrates, driving each detection contact 51 to descend, and the extended cross bar 5 descends based on the descent of the running board position with the largest deformation detected by the detection contact 51, driving the detection rod 3 to descend to block a preset number of through-beam infrared sensors. The CPU controller receives the signal of the through-beam infrared sensor and then counts the steps. When the number of through-beam infrared sensors blocked by the detection rod 3 when it descends is less than the preset value, it is considered to be invalid vibration and no steps are counted.

[0028] Preferably, an electric telescopic rod 32 is embedded in the bottom end of the detection rod 3, and the electric telescopic rod 32 is electrically connected to the CPU controller so as to reduce the number of used through-beam infrared sensors. Different weights of users cause different vibration strokes of the running board when using the treadmill. By adjusting the position of the bottom end of the detection rod 3 by telescoping the electric telescopic rod 32, the different vibration strokes caused by weight can be offset, thereby avoiding increasing the number of used through-beam infrared sensors to accommodate different weights.

[0029] Preferably, a pressure sensor 31 is embedded in the bottom of the limit block, and the pressure sensor 31 contacts the top of the reset spring 4. The pressure sensor 31 is electrically connected to the CPU controller and is used to trigger the start of the opposing infrared sensor. Initially, each opposing infrared sensor is in a dormant state. When the pressure sensor 31 detects the pressure of the reset spring, each opposing infrared sensor is turned on.

[0030] Preferably, a guide groove 22 is also provided on the limiting boss 2 and passes through the interior of the mounting shell 1. A guide rod adapted to the guide groove 22 is vertically provided at the bottom of the extending cross bar 5. The guide rod is slidably inserted into the guide groove 22. The guide groove 22 and the guide rod are used to guide the lifting and lowering of the detection rod 3.

[0031] Preferably, the extending direction of the extension cross bar 5 is parallel to the extending direction of the running deck of the treadmill, and the detecting contacts 51 are evenly distributed along the extending direction of the extension cross bar 5 .

[0032] In the manufacturing process of treadmills, in order to save costs, the extended length of the running board is greater than its width, and the error of the vibration stroke in the extended direction is also greater than the error in the width direction.

[0033] Preferably, an elastic member is provided on the top of the detection contact 51 , and the elastic member is used to prevent the detection contact 51 from colliding with the rigidity of the running board.

[0034] Preferably, a fixing groove 11 is provided at the bottom of the side wall of the mounting shell 1 , and a fixing hole is provided at the bottom of the fixing groove 11 . The fixing groove 11 is used for fixing in the present application.

[0035] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.

[0036] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it does not limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
