[0044] As shown in Figure 1 and Figure 3 , it is the motion detection device 10 for fitness equipment provided by the first embodiment of the utility model, including weight module 11, distance detection module and control electronic watch.Distance detection module is connected with weight module 11, for detecting the moving distance and moving speed of weight module 11;Simultaneously distance detection module is connected with control electronic watch, and the parameters obtained by distance detection module can be displayed through control electronic watch.Control electronic watch is connected with weight module 11, identifies the weight size selected by user at this time, and displays.

[0045] Please refer to Figure 1 , Figure 3 , Figure 6The weight module 11 comprises a movable rod 111, a plurality of weight blocks 112 stacked on the movable rod 111, and a pin 113. When the pin 113 is connected to the weight blocks 112 and the movable rod 111, and the movable rod 111 is driven to move vertically upward, the weight blocks 112 and the pin 113 move vertically upward synchronously. During the exercise, the user selectively connects the pin 113 to the weight blocks 112 and the movable rod 111 to adjust the exercise resistance weight. At this time, the greater the weight selected, the more the pin 113 is inserted downward. Specifically, the weight blocks 112 are provided with horizontally arranged first insertion holes 1121, and the movable rod 111 is provided with a plurality of second insertion holes 1111 matched with the first insertion holes 1121. When the weight is selected, the pin 113 is selectively inserted into the first insertion holes 1121 and the second insertion holes 1111, so that the inserted weight blocks 112 and the weight blocks 112 above can move synchronously with the movable rod 111.

[0046] Further, the pin 113 comprises a rotatingly connected pin handle 114 and a pin head 115. The outer wall of the pin handle 114 is provided with a first clamping arm 1141, and the pin head 115 is provided with a second clamping arm 1151 at the end extending towards the pin handle 114. When the pin handle 114 and the pin head 115 are relatively rotated, the first clamping arm 1141 and the second clamping arm 1151 are relatively rotated synchronously, thereby adjusting the angle difference between the first clamping arm 1141 and the second clamping arm 1151. In addition, the first insertion hole 1121 extends radially with a first clamping groove 1123 and a second clamping groove 1122. When the first clamping arm 1141 and the first clamping groove 1123 are matched, and the second clamping arm 1151 and the second clamping groove 1122 are matched, the pin 113 can be inserted into the first insertion hole 1121.

[0047] As shown in Figure 3 The angle difference between the first clamping groove 1123 and the second clamping groove 1122 of the first insertion hole 1121 of each weight block 112 is different. When the weight is selected, the pin handle 114 and the pin head 115 need to be relatively rotated to adjust the angle difference between the first clamping arm 1141 and the second clamping arm 1151, so as to be inserted into the first insertion hole 1121 of the specific weight block 112. Therefore, the weight of the weight block 112 can be identified according to the angle difference between the first clamping arm 1141 and the second clamping arm 1151, that is, the angle difference between the first clamping arm 1141 and the second clamping arm 1151 corresponds to the total weight of the weight block 112.

[0048] In addition, the plug-in 113 is electrically connected to the control electronic watch, the plug-in 113 has current passing through, at this time, the angle difference between the first clamping arm 1141 and the second clamping arm 1151 will affect the resistance value, and then affect the current size; from the above, the current size and the total weight of the counterweight block 112 are one-to-one corresponding. Therefore, the control electronic watch can obtain the total weight of the counterweight block 112 at this time according to different current sizes, and display.

One end of the positioning assembly 116 abuts against the positioning groove 1143, so as to limit the rotation of the plug-in head 115 and the plug-in handle 114. In the embodiment, the positioning assembly 116 includes a connecting cover 1161, a spring 1162 and a positioning bead 1163; the connecting cover 1161 is fixed at one end of the through hole 1153 away from the plug-in head 115, one end of the spring 1162 is fixedly connected with the connecting cover 1161 by welding, glue dispensing or other connecting methods, and the positioning bead 1163 is fixed at the other end of the spring 1162; under the elastic force of the spring 1162, the positioning bead 1163 always abuts against the positioning groove 1143, so as to avoid that the plug-in handle 114 and the plug-in head 115 automatically rotate relative to each other without external force. It can be known that the position of the positioning groove 1143 determines the angle difference between the first clamping arm 1141 and the second clamping arm 1151; and the number of the positioning groove 1143 determines the number of the angle difference with gears. In the embodiment, 16 grooves are arranged, and correspondingly, the first clamping arm 1141 and the second clamping arm 1151 have 15 kinds of angle differences, which also determines that the weight module 11 of the embodiment includes 15 counterweight blocks 112.

During the movement, the gyroscope 12a detects the movement speed and movement distance, so as to obtain the movement speed and movement distance of the counterweight blocks 112. Meanwhile, the gyroscope 12a is connected with a control electronic watch, the control electronic watch receives the movement speed and movement distance and displays them on the control electronic watch. It is further explained that the connection mode of the gyroscope 12a and the control electronic watch can be selected as a wireless connection mode such as Bluetooth and Internet, and can also be a wired connection.
