Detailed Description

Fig. 1 is a schematic diagram of an intelligent weight training machine according to an embodiment of the present invention, fig. 2 is a schematic diagram of an installation structure of the training weight detecting device of fig. 1 according to the present invention, fig. 3 is a partially enlarged schematic diagram of the intelligent weight training machine of fig. 1 according to the present invention, fig. 4 is a schematic diagram of the weight detecting latch of fig. 1 according to the present invention, and fig. 5 is a schematic diagram of the weight tag of fig. 1 according to the present invention. Referring to fig. 1-5 together, the intelligent weight training machine 10 includes a weight training machine 102 and a training weight detecting device 100 mounted on the weight training machine 102. The weight training machine 102 is an exercise machine having a plurality of weights 104. A user may select a particular number of weights 104 to determine a training weight for exercise. In fig. 1, the weight training Machine 102 is a Shoulder Press (converting Chest Press Machine), and in other embodiments, the weight training Machine 102 may be an exercise Machine such as a Chest Press Machine (converting Chest Press Machine), a Leg Press Machine (Leg Press Machine), an Abdominal crimper (Abdominal Crunch Machine), or a Leg crimper (Leg Extension Machine), although the invention is not limited thereto.

The training weight detecting device 100 includes a weight detecting pin 110, a plurality of weight tags 120 and a computing device 130. The weight tags 120 are respectively disposed on the weight blocks 104, and each weight tag 120 includes a plurality of reflection areas 122, such as 5 reflection areas 122 in fig. 5, but the invention is not limited to the number of reflection areas 122. The weight label 120 may be attached, adhered, or embedded by magnetic force to each weight 104, and the reflective region 122 is disposed on the outward facing surface S1 of the weight label 120.

The weight detecting pin 110 is used to insert one of the weights 104 to determine a training weight. In detail, the weights 104 in fig. 1 are stacked in the Z direction, and a driving rod (not shown) penetrating the weights 104 is provided inside. Each weight 104 has a through hole H in the Y direction. The base of the weight detecting latch 110 is provided with a rod body 112. The user inserts the shaft 112 of the weight detecting pin 110 into the through hole H of a selected one of the weights 104 and engages with the hole of the inner driving shaft. The drive rod body is connected to a drive element 106, such as a cable or belt. The transmission element 106 is used to move at least one of the weights 104. By means of the transmission element 106, the user can lift the weight 104 inserted by the weight detecting pin 110 and other weights 104 above the weight 104 by pulling force, wherein the total weight of the pulled weights 104 is the training weight mentioned herein.

In fig. 4, the weight detecting bolt 110 includes a plurality of transmitters 114 and a plurality of receivers 116. The emitters 114 are disposed on the surface S2 of the base B along with the receivers 116 and the shaft 112. When the user inserts the weight detecting pin 110 into the weight 104, the surface S2 and the surface S1 are opposite to each other, and the emitters 114 and the reflection areas 112 are arranged in a one-to-one correspondence. More specifically, in this embodiment, a transmitter 114 and a receiver 116 are combined into a set of detecting elements 115, the number of detecting elements 115 matches the number of reflecting areas 122, and the positions of the two are corresponding when the weight detecting pin 110 is inserted into the weight 104. When the weight detecting pin 110 is inserted into the weights 104, the transmitters 114 transmit detecting signals to the weight tags 120 on selected ones of the weights 104, and the reflective areas 122 reflect the detecting signals from the corresponding transmitters 114. The receivers 116 may receive the detection signals reflected by the reflective regions 122.

The detecting element 115 may be an optical sensing element. For example, the transmitter 114 is an infrared transmitter, the emitted sensing signal is infrared, and the receiver 116 is an infrared receiver for receiving the sensing signal of infrared, but the invention is not limited thereto. In other embodiments, the detecting element 115 may also be a Quick Response (QR) code reading device or a detecting element with NFC pairing function.

Although the computing device 130 is disposed above the weight 104 in fig. 1, the position of the computing device 130 is not limited in the present invention. The computing device 130 can be electrically connected to the weight detecting pins 110 by wire or wirelessly, and obtain the training weight value according to the detecting signals received by the receivers 116.

In short, when the weight detecting pin 110 is inserted into one of the weights 104, the weight detecting pin 110 will send a detecting signal to detect the weight tag 120 on the inserted weight 104, and the computing device 130 can obtain which weight 104 is selected according to the detecting signal and automatically record the value of the training weight. The intelligent weight training machine 10 can automatically record the training weight selected by the user without the need for the user to spend additional steps, which can facilitate the user's operation and avoid the possibility of manual miscounting by the user.

Additional implementation details of the intelligent weight training machine 10 are disclosed further below.

In fig. 4 and 5, each weight tag 120 further includes a first magnetic element 124, and the weight detecting pin 110 further includes a second magnetic element 118, wherein the first magnetic element 124 and the second magnetic element 118 are, for example, magnets. First magnetic element 124 may be disposed on the back side (opposite surface S1) of weight label 120, although the invention is not limited thereto. If the weight 104 is an iron block, the weight label 120 may be attracted beside the through hole H of the weight 104 by the magnetic force of the first magnetic member 124. A second magnetic element 118 is also disposed on surface S2 of base B, but on the opposite side of the transmitters 114 from the receivers 116. In fig. 4, the transmitters 114 and the receivers 116 are located on the left side of the stick 112, and the second magnetic element 118 is located on the right side of the stick 112, wherein the second magnetic element 118 and the first magnetic element 124 are magnetically mutually exclusive.

In one embodiment, the reflective area 122 of the weight detecting pin 120 overlaps the first magnetic element 124, so that when the user inserts the weight detecting pin 110 into the weight 104, if the right side of the shaft 112 faces the weight detecting pin 120, the user will perceive that the inserting direction of the weight detecting pin 110 is incorrect because the second magnetic element 118 and the first magnetic element 124 are magnetically repulsive. That is, when the weight detecting pin 110 is inserted into the weight 104, the detecting element 115 is not aligned to the reflective area 122 of the weight label 120. The user may rotate the weight detecting latch 110 to have the side with the transmitter 114 facing the weight tag 120.

Each reflective region of the weight tags 120 has a first encoded state or a second encoded state, so that the reflective regions 122 on each weight tag 120 can be grouped into a set of codes corresponding to the values of the training weight. In the present embodiment, the first encoded state or the second encoded state corresponds to the reflectivity of the reflective region 122. For example, the first encoding state is white, corresponding to high reflectivity, and the second encoding state is black, corresponding to low reflectivity. In fig. 5, from left to right, the encoding states of the 5 reflection regions 122 are sequentially "black, white, black and black" from top to bottom, and may represent a binary code such as "01100" (black represents "0" and white represents "1"). In this embodiment, the encoding method is only an example, and the present invention is not limited thereto, and in some embodiments, the reflective region 122 may have other gray levels to expand the encoding method.

FIG. 6 is a block diagram of a weight detecting pin and computing device according to an embodiment of the invention. Referring to fig. 6, the weight detecting pin 200 and the computing device 300 are used for the weight detecting pin 110 and the computing device 130 of fig. 1.

The weight detecting latch 200 includes a first communication module 210, a magnetic switch 220, a timer 230, a motion detector 240, and a detecting element module 250, wherein the detecting element module 250 includes a plurality of transmitters 114 and a plurality of receivers 116 (fig. 6 shows only one transmitter 114 and one receiver 116 as a representative). The computing device 300 includes a second communication module 310, a memory 320, a control device 330 and a motion detection device 340.

The first communication module 210 and the second communication module 310 can connect the weight detecting pin 200 and the computing device 300 through wireless communication or wired communication. The first communication module 210 and the second communication module 310 are wireless communication modules supporting Bluetooth (Bluetooth) in this embodiment, but the invention is not limited thereto.

The memory 320 may be any type of fixed or removable Random Access Memory (RAM), read-only memory (ROM), flash memory (flash memory), hard disk or other similar device, integrated circuit, and combinations thereof, but the invention is not limited thereto.

The control device 330 includes a hardware device such as a Central Processing Unit (CPU), a Microprocessor (Microprocessor), or a Microcontroller (MCU), for example, but the present invention is not limited thereto.

The first communication module 210 of the weight detecting pin 200 is used for transmitting weight information obtained according to the detection signal to the computing device 300. In this embodiment, the control device 330 can receive a code, such as "01100", of a selected weight 104 from the weight detecting latch 200 via the second communication module 310. The memory 320 may store a look-up table LUT, wherein the look-up table LUT records a value of the code and the corresponding training weight in advance. For example, the code "00001" represents a training weight of 2 kg, the code "00010" represents a training weight of 4 kg, the code "01100" represents a training weight of 48 kg, and so on, without limitation.

In another embodiment, the look-up table LUT can be stored in the weight check pin 200, and the weight check pin 200 directly transmits the training weight value as the weight information to the computing device 300. In other embodiments, the look-up table LUT may also be stored in the cloud server or the host, and the comparison between the pre-recorded code and the corresponding training weight value is performed by the cloud server or the host, and since the operations of storing the look-up table LUT and the operation comparison are both given to the cloud server or the host, the corresponding component cost and operation processing can be reduced in the weight detecting pin 200 or the computing device 300, thereby achieving the effects of saving cost and power.

The magnetic switch 220 electrically connects the transmitters 114 and the receivers 116 for turning on or off the transmitters 114 and the receivers 116. When a user inserts the weight detecting latch 200 into a selected weight 104, the magnetic switch 220 senses the magnetic force of the first magnetic member 124 of the weight tag 120. When the magnetic switch 220 detects that the magnetic force of the first magnetic element 124 is greater than or equal to the activation threshold, the magnetic switch 124 activates the transmitters 114 and the receivers 116, so that the transmitters 114 start to send out detection signals. Then, when the receiver 116 receives the reflected detection signal, the magnetic switch 220 turns off the transmitters 114 and the receivers 116, and after the transmitters 114 and the receivers 116 are turned off, the magnetic switch 220 is automatically turned off. Alternatively, the magnetic switch 200 may be selected to remain on after the receiver 116 receives the reflected detection signal. The magnetic switch 220 may be turned off after the transmitters 114 and the receivers 116 are activated. The magnetic switch 220 is, for example, a reed switch (reed switch) or a hall effect sensor (hall effect sensor), but the invention is not limited thereto. It is added that the magnetic switch 220 does not turn off the transmitters 114 and the receivers 116 if the transmitters 114 and the receivers 116 have not successfully read the numbers on the weight tags 120.

The motion detector 240 is electrically connected to the magnetic switch 220. When the magnetic switch 220 is turned off, the motion detector 240 detects that the weight detecting latch 200 is pulled out of the selected weight 104, and the motion detector 240 activates the magnetic switch 220. Specifically, the motion detector 240 may be a gravity sensor (G-sensor), an acceleration sensor (Accelerometer sensor), or the like. That is, when the user pulls the weight detecting pin 200 out of the through hole H of the weight block 104, the motion detector 240 can detect the pulling motion, so as to restart the magnetic switch 220, so that the magnetic switch 220 can sense whether the user inserts the weight detecting pin 200 into one of the weight blocks 104 again, so as to determine whether to perform the detection motion of the weight tag 120. In one embodiment, the motion detector 240 may remain in an on state at all times.

The timer 230 is electrically connected to the magnetic switch 220, and is configured to start timing the weight detection time since the magnetic switch 220 is activated. When the weight detection time is greater than or equal to the time threshold and the magnetic switch 220 does not detect the magnetic force of the first magnetic element 124, the magnetic switch 220 is automatically turned off. Thereafter, when the motion detector 240 detects that the weight detecting pin 200 is moved, for example, a user inserts the weight detecting pin 200 into the weight 104 again, the motion detector 240 activates the magnetic switch 220 to allow the magnetic switch 220 to detect whether the weight detecting pin 200 is inserted into the weight 104.

In short, the present embodiment controls the weight detecting pin 200 to automatically perform the detecting operation through the two-stage switch, thereby achieving the effects of energy saving and power saving.

The motion detection device 340 of the computing device 300 is coupled to the transmission element 106 of the weight training machine 102 and. When the user exercises, the weight 104 is partially driven by the transmission element 106, and the motion detecting device 340 can measure the movement of the transmission element 106 to generate a movement detecting signal. The control device 330 of the arithmetic device 300 may obtain the number of times of training, the training speed, the training acceleration, the training distance, or the training time from the movement detection signal.

That is, the computing device 300 can obtain the training weight selected by the user through the weight detecting latch 200, and the computing device 300 can monitor the exercise status of the user through the motion detecting device 340, such as the speed, acceleration, distance of the user pulling the weight 104, or the number of times or groups of the user training, or the exercise time of the user. Based on the training data, the computing device 300 can analyze the weight training performance of the user, such as the force curve or the power curve.

In an embodiment, the computing device 300 may also transmit the training data (such as the value of the training weight and at least one of the training times, the training speed, the training acceleration, the training distance and the training time) to the weight training management system 400 through the second communication module 310. The weight training management system 400 is, for example, a cloud server or a host, and the weight training management system 400 analyzes the weight training performance of the user.

In summary, the present invention provides an intelligent weight training machine and a training weight detecting device. The training weight detecting device has a simple structure, is low in production cost and is easy to combine with different weight training machines. In addition, the device has the advantage of simple installation. The training weight detection device can automatically detect the training weight selected by the user after being installed on the weight training machine, and even can further detect the training state of the user and analyze the weight training efficiency of the user. Therefore, the intelligent fitness effect is achieved.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
