[0051] Understandably, resistance bands are a common piece of fitness equipment that is very simple to use and is popular among fitness enthusiasts, primarily used for stretching exercises.

[0052] However, the existing elastic bands cannot count, so how to make the elastic bands have a counting function is a problem that needs to be solved urgently.

[0053] Therefore, in order to solve the above defects, this embodiment provides an elastic band, which can be provided with a counting circuit and a piezoelectric circuit with a piezoelectric part, and the piezoelectric part is arranged at the cross contact point formed by the elastic line, and the piezoelectric circuit is connected to the counting circuit. In actual use, since the two elastic lines will contact, and the pressure generated by the contact is different due to different stretching degrees, the piezoelectric circuit can generate a pressure signal when the elastic lines contact and transmit it to the counting circuit, and the counting circuit can count according to the pressure signal. Compared with the existing elastic band, the elastic band in this embodiment can count.

[0054] For ease of understanding, the following combination Figures 1 to 8 The elastic band provided in the embodiment of the present application is introduced in detail.

[0055] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the elastic band of the present application. The first embodiment of the elastic band of the present application is proposed. Figure 1 As shown, in this embodiment, the elastic band includes:

[0056] At least two elastic lines are cross-wound and form at least one cross-contact point.

[0057] It should be noted that the elastic band provided in this embodiment can be any elastic tension band, specifically an elastic band used in the field of fitness, and of course, it can also be an elastic band used in other fields. This embodiment uses an elastic band in the field of fitness for illustration.

[0058] It should also be noted that the elastic band in this embodiment can be made of a plurality of elastic threads, and the elastic threads can be elastic fiber threads, and the elastic threads can be made of fibers, such as spandex, etc., and this embodiment does not impose any limitation on this.

[0059] It is understandable that the elastic band in this embodiment can be formed by at least two elastic lines being cross-wound, such as Figure 1 As shown, Figure 1 The first elastic wire and the second elastic wire can of course be formed by more elastic wires being crossed and wound, and two are used for illustration in this embodiment. When crossing, it is ensured that there is at least one crossing contact point, that is, there is at least one crossing and the two elastic wires are in contact at the crossing.

[0060] In this embodiment, the elastic band further includes: a piezoelectric circuit provided with a piezoelectric portion, wherein the piezoelectric portion is located at the cross contact point, and the piezoelectric circuit is used to generate a pressure signal when the elastic lines are in contact.

[0061] It should be understood that the piezoelectric part may be a component for detecting the pressure, and may specifically be a piezoelectric material, such as a piezoelectric crystal, a piezoelectric ceramic or a new organic polymer piezoelectric material, etc. This embodiment does not impose any limitation on this.

[0062] It should also be understood that the piezoelectric circuit may be a circuit that outputs a pressure signal when the piezoelectric portion detects pressure. The piezoelectric portion in this embodiment may be disposed at the cross-contact point, such as Figure 1 As shown, when the two elastic lines are in contact, since the piezoelectric part is disposed between the two elastic lines, the piezoelectric circuit can generate a pressure signal.

[0063] Further, in order to facilitate the setting of the piezoelectric portion, refer to Figure 2 , Figure 2 This is a schematic diagram of the position of the piezoelectric part in the first embodiment of the elastic band of this application, as shown in Figure 2 As shown, in this embodiment, the piezoelectric part can be attached to the surface of the cross contact point of one of the elastic ropes (for example Figure 2 The cross contact point 1 in the middle), and then the pressure applied by the other elastic rope can be detected through this position; of course, it can also be set inside the cross contact point of one of the elastic ropes (for example Figure 2 The cross contact point 2 in the middle), the pressure applied by another elastic rope can also be detected through this position. The specific position can be set according to the actual situation, and this embodiment does not limit this.

[0064] In this embodiment, the elastic band further includes: a counting circuit, which is electrically connected to the piezoelectric circuit and is used to count according to the pressure signal.

[0065] Reference Figure 3 , Figure 3 This is a circuit structure diagram of the first embodiment of the elastic band of this application. Figure 3 As shown, in this embodiment, a counting circuit may be further provided on the elastic band, and the counting circuit may be electrically connected to the piezoelectric circuit. The counting circuit may be specifically provided at any position of the elastic band, and this embodiment does not impose any limitation on this.

[0066] It should be noted that the counting circuit may be a circuit that counts according to a pressure signal, and may specifically be a microcontroller unit (MCU). Of course, it may also be other devices that realize similar functions, and this embodiment does not impose any limitation on this.

[0067] In a specific implementation, since the elastic band is woven from at least two elastic threads, the cross-contact points will also be in contact when the user does not stretch it, and the piezoelectric circuit will continue to output a pressure signal, but when the user stretches it, the pressure signal will change with the pressure between the two elastic threads.

[0068] In actual use, when the user stretches the elastic band back and forth, due to elastic deformation, the two elastic ropes will be squeezed toward the middle, and then the pressure at the cross contact point will change. The piezoelectric part can collect the pressure change, and the piezoelectric circuit generates a corresponding piezoelectric signal according to the pressure change and transmits it to the counting circuit. The counting circuit can count according to the change of the piezoelectric signal, thereby realizing the counting function.

[0069] Further, continue as Figure 3 As shown, in this embodiment, the piezoelectric circuit further includes: a detection module; the piezoelectric part includes: a first piezoelectric element;

[0070] The detection module is electrically connected to the first piezoelectric element and the counting circuit respectively, and the first piezoelectric element is arranged on one of the elastic lines;

[0071] The detection module is used to generate a pressure signal when the first piezoelectric element detects the contact of the elastic line.

[0072] It is understandable that the first piezoelectric element can be the piezoelectric material. The first piezoelectric element can be arranged at any cross contact point of the elastic line, specifically on the surface of the elastic line or inside the elastic line, which is not limited in this embodiment.

[0073] It is understandable that the above-mentioned detection module can be a module that generates a pressure signal, that is, a module that generates a corresponding voltage when the first piezoelectric element detects pressure. In actual use, when the first piezoelectric element is set on the surface of the elastic line, the user does not stretch the elastic band, and the first piezoelectric element may also contact another elastic line. The detection module will also generate a corresponding pressure signal and transmit it to the counting circuit. When the user stretches, the pressure between the first piezoelectric element and the other elastic line changes, and the detection module generates a corresponding pressure signal and transmits it to the counting circuit. The counting circuit can count according to the change of the pressure signal;

[0074] When the first piezoelectric element is arranged inside the elastic rope, the principle is similar to that of being arranged on the surface as mentioned above, except that the pressure of the first piezoelectric element comes from the elastic rope on which the first piezoelectric element is arranged after the two elastic ropes come into contact. Therefore, this embodiment will not be described in detail.

[0075] Further, considering that the accuracy of setting a piezoelectric element measurement may be low, continue as Figure 3 As shown, in this embodiment, the piezoelectric part further includes: a second piezoelectric element;

[0076] The second piezoelectric element is electrically connected to the detection module, and the second piezoelectric element is arranged on another elastic wire;

[0077] The detection module is further configured to generate a pressure signal when the first piezoelectric element and the second piezoelectric element detect that the elastic line is in contact.

[0078] It should be understood that the second piezoelectric element can also be a piezoelectric material. In this embodiment, the second piezoelectric element can be arranged on the cross contact point of another elastic rope, which can be the surface of the elastic rope, or the inside thereof, and this embodiment is not limited to this, so that the first piezoelectric element and the second piezoelectric element are in direct or indirect contact.

[0079] Furthermore, both elastic ropes are provided with piezoelectric elements, and the first piezoelectric element on one of the elastic ropes can be set as the positive electrode, and the piezoelectric element on the other elastic rope can be set as the negative electrode. This embodiment uses the first piezoelectric element as the positive electrode and the second piezoelectric element as the negative electrode for explanation, and then in actual use, the user does not stretch, the first piezoelectric element and the second piezoelectric element are in direct or indirect contact, so the first piezoelectric element will also detect pressure, and the detection module can generate a corresponding pressure signal to transmit to the counting circuit; when the user stretches, the first piezoelectric element detects the pressure change, and the detection module can generate a corresponding pressure signal to transmit to the counting module.

[0080] This embodiment may be provided with a counting circuit and a piezoelectric circuit with a piezoelectric part, and the piezoelectric part is arranged at the cross contact point formed by the elastic wire, and the piezoelectric circuit is connected to the counting circuit. In actual use, since the two elastic wires will contact, and the pressure generated by the contact is different due to different stretching degrees, the piezoelectric circuit can generate a pressure signal when the elastic wires contact and transmit it to the counting circuit, and the counting circuit can count according to the pressure signal. Compared with the existing elastic band, the elastic band in this embodiment can count.

[0081] Reference Figure 4 , Figure 4 This is a circuit structure block diagram of the second embodiment of the elastic band of the present application. Based on the above-mentioned first embodiment, the second embodiment of the elastic band of the present application is proposed.

[0082] Furthermore, in order to determine whether the elastic band is currently in a normal state or a stretched state, the present embodiment can set a pressure signal with a corresponding voltage value according to different states for subsequent detection. Therefore, in the present embodiment, the piezoelectric circuit is also used to generate a pressure signal with a voltage value of a first target voltage value when the contact pressure between the elastic lines reaches a first preset pressure threshold;

[0083] The piezoelectric circuit is further configured to generate a pressure signal having a voltage value of a second target voltage value when the contact pressure reaches a second preset pressure threshold;

[0084] The first preset pressure threshold is smaller than the second preset pressure threshold, and the first target voltage value is smaller than the second target voltage value.

[0085] It should be noted that the first preset pressure threshold may be the pressure value of the cross contact point of the two elastic cords when the elastic belt is in a normal state, that is, not stretched, and the second preset pressure threshold may be the pressure value of the cross contact point of the two elastic cords when the elastic belt is in a stretched state. Both the first preset pressure threshold and the second preset pressure threshold may be set according to actual conditions, and this embodiment does not limit this.

[0086] It should also be noted that the above-mentioned first target voltage value and the above-mentioned second target voltage value can be set according to actual conditions, and in this embodiment, the piezoelectric circuit can be set to have a higher voltage value of the pressure signal when the pressure is greater, and thus the first target voltage value can be set to 3.3V and the second target voltage value can be set to 5V.

[0087] Since it is necessary to output pressure signals with different voltage values, the detection module may be a module that outputs pressure signals with corresponding voltage values ​​according to different pressures detected by the first piezoelectric element, and this embodiment does not impose any limitation on this.

[0088] Reference Figure 5 , Figure 5 This is a schematic diagram of the piezoelectric portion contact in the second embodiment of the elastic band of this application. Figure 5 As shown, in actual use, when the elastic rope is not woven into an elastic band, the detection module can output a pressure signal with a voltage value of 0V, that is, Figure 5 The first piezoelectric element and the second piezoelectric element are not in a squeezed state; when the elastic rope is woven into an elastic band, but the user does not stretch the elastic band, the detection module can output a pressure signal with a voltage value of 3.3V and transmit it to the counting module, that is, Figure 5 The first piezoelectric element and the second piezoelectric element are in a normal squeeze state; when the user stretches the elastic band, the detection module can output a pressure signal with a voltage value of 5V and transmit it to the counting module, that is, Figure 5 The first piezoelectric element and the second piezoelectric element are in a heavy squeeze state. The counting module can determine whether it is currently stretched according to the 3.3V pressure signal and the 5V pressure signal, and complete the counting according to the pressure signal.

[0089] Furthermore, in order to complete the counting, Figure 4 As shown, in this embodiment, the counting circuit includes: a comparison module and a processing module;

[0090] The comparison module is electrically connected to the piezoelectric circuit and the processing module respectively;

[0091] The comparison module is used to compare the voltage value of the pressure signal with a preset voltage threshold, and transmit the generated comparison signal to the processing module;

[0092] The processing module is used to count according to the comparison signal.

[0093] It should be noted that the comparison module may be a module with a comparator. The preset voltage threshold may be a threshold for determining whether the elastic band is stretched, and may be between the first target voltage value and the second target voltage value, i.e., between 3.3V and 5V. The preset voltage threshold may be set according to actual conditions, and this embodiment does not limit this.

[0094] It should also be noted that the processing module may be a module with an MCU. And because the comparator outputs a level signal of 1 or 0, the processing module may have a pulse width modulation (PWM) interface connected to the comparison module.

[0095] In actual use, when the user does not stretch the elastic band, the detection module can output a 3.3V pressure signal to the comparison module. The comparison module detects that the voltage value of the pressure signal is lower than the preset voltage threshold, and then the output comparison signal level is low level 0. The processing module can know that it is not stretched at this time. When the user stretches the elastic band, the detection module can output a 5V pressure signal to the comparison module. The comparison module detects that the voltage value of the pressure signal is higher than the preset voltage threshold, and then the output comparison signal level is high level 1. The processing module can know that it is stretched at this time. Therefore, when the user stretches back and forth, the voltage value of the pressure signal output by the detection module jumps back and forth between 3.3V and 5V, and the comparison signal output by the comparison module jumps back and forth between low level 0 and high level 1, forming a pulse voltage transmitted to the processing module. The processing module can count according to the number of high level 1 in the comparison signal as the number of stretching times.

[0096] Furthermore, in order to facilitate the sending of the counting result to the user's terminal device (such as a watch, mobile phone, bracelet, earphone, etc.) for display so that the user can observe, continue as follows Figure 4 As shown, in this embodiment, the counting circuit further includes: a transmission module;

[0097] The transmission module is electrically connected to the terminal device and the processing module respectively;

[0098] The transmission module is used to transmit the counting result generated by the processing module to the terminal device, so that the terminal device prompts the counting result.

[0099] It is understandable that the transmission module can be a module for connecting to a terminal device, which can be a wired connection or a wireless connection. In order to improve the user experience, in this embodiment, a wireless connection is adopted between the transmission module and the terminal device, and the transmission module can be a module supporting wireless fidelity (WiFi) or a module supporting Bluetooth connection, which is not limited in this embodiment.

[0100] It is also understandable that in order to enable the processing module to be connected to the transmission module, the processing module may also be provided with a general purpose input / output (GPIO) interface, and connected to the transmission module through the GPIO interface.

[0101] Reference Figure 6 , Figure 6 This is a schematic diagram of the counting process in the second embodiment of the elastic band of this application. Figure 6 As shown, in actual use, the user stretches the elastic band (i.e. Figure 6 The user uses the elastic band), and the piezoelectric part detects the pressure change (i.e. Figure 6 The cross contact point in the middle is deformed), and the piezoelectric circuit outputs the corresponding piezoelectric signal (i.e. Figure 6 The piezoelectric circuit output voltage jumps), and the comparison module outputs a corresponding comparison signal according to the piezoelectric signal (i.e. Figure 6 The comparator outputs a pulse signal), and the processing module counts according to the comparison signal (i.e. Figure 6 The microprocessor PWM receives the pulse waveform) and transmits the counting result to the user's mobile terminal (i.e. Figure 6 The microprocessor transmits data to the electronic device through the transmission module), so that the mobile terminal can display a prompt after receiving the counting result.

[0102] As another implementation, since mobile terminals generally have speakers, the mobile terminal can also broadcast a prompt after receiving the counting result.

[0103] Furthermore, in order to realize the timing of the exercise duration, in this embodiment, the counting circuit is also used to determine the current exercise duration according to the pressure signal.

[0104] Specifically, since the comparison module can output a comparison signal of low level 0 or high level 1. In actual use, when the processing module detects the comparison signal of high level 1 for the first time, it can determine that the user has started exercising and start timing. When the high level 1 is not received within the preset time after the low level 0 is detected, it can be determined that the exercise is over, and the time between the moment of first receiving the high level 1 and the moment of last receiving the low level 0 is used as the current exercise time. The preset time can be set according to the actual situation, and this embodiment does not limit this.

[0105] Similarly, the current exercise duration can be sent to the mobile terminal through the transmission module, so that the mobile terminal displays the current exercise duration, or makes a broadcast prompt, etc. This embodiment does not limit this.

[0106] Reference Figure 7 , Figure 7 This is a structural schematic diagram of the third embodiment of the elastic band of the present application. Based on the above embodiments, the third embodiment of the elastic band of the present application is proposed.

[0107] like Figure 7 As shown, in this embodiment, the elastic line has a gripping section and a detection section;

[0108] The piezoelectric part is arranged in the detection section, and the counting circuit is arranged in the holding section.

[0109] It should be noted that the detection section may be a section in the elastic band for counting detection, and the holding section may be a section held by the user for stretching. In this embodiment, the piezoelectric part may be disposed in the detection section, and the counting circuit may be disposed in the holding section for user operation.

[0110] For the convenience of users, the present embodiment may mark the holding section, for example, using a color mark different from the detection section, to prevent the user from mistakenly holding the detection section during stretching, thereby affecting the counting result.

[0111] To improve accuracy, continue Figure 7 As shown, in this embodiment, the two opposite ends of the elastic band can be used as gripping sections, and a section between the two gripping sections can be used as a detection section, so there can be two detection sections. Of course, one detection section or more detection sections can also be set, and this embodiment does not limit this.

[0112] Furthermore, in order to facilitate the user's holding and prevent the external influence on the circuit, the elastic band also includes:

[0113] A first shell, wherein the first shell is sleeved on the outside of the gripping section, and the counting circuit is arranged in the first shell;

[0114] The second shell is sleeved on the outside of the detection section, and the piezoelectric circuit is arranged in the second shell.

[0115] It is understandable that in this embodiment, the first housing can be provided at the gripping sections at both ends, and the first housing can be provided in a form that is convenient for the user to hold, and can be provided according to actual conditions, and this embodiment does not limit this. The counting circuit can be provided in any of the housings, thereby preventing the user from affecting the counting circuit when holding the device.

[0116] Similarly, in this embodiment, the second housing mentioned above can be provided outside the two detection sections. The second housing can be in any form for accommodating the piezoelectric circuit, and can be provided according to actual conditions. This embodiment does not limit this. The piezoelectric circuit can be provided in the second housing. Since there are two detection sections, two piezoelectric circuits can be provided in this embodiment, which are respectively provided in the corresponding second housings and are both connected to the counting circuit.

[0117] Furthermore, considering that it may be inconvenient for user training if the piezoelectric circuit in the detection section is connected to the counting circuit in the holding section through a cable, Figure 8 , Figure 8 This is a circuit structure block diagram of the third embodiment of the elastic band of the present application.

[0118] like Figure 8 As shown, in this embodiment, the elastic band further includes: a transmitting circuit and a receiving circuit;

[0119] The transmitting circuit is electrically connected to the piezoelectric circuit, the transmitting circuit is also wirelessly connected to the receiving circuit, and the receiving circuit is also electrically connected to the counting circuit;

[0120] The transmitting circuit is used to transmit the pressure signal to the receiving circuit;

[0121] The receiving circuit is used to transmit the pressure signal to the counting circuit.

[0122] It should be understood that the above-mentioned transmitting circuit and receiving circuit may be circuits for realizing wireless connection, such as a Bluetooth transmitting circuit and a Bluetooth receiving circuit, etc., and this embodiment does not limit this.

[0123] In this embodiment, the transmitting circuit can be specifically connected to the detection module in the piezoelectric circuit, and the receiving circuit can be specifically connected to the comparison module in the counting circuit. The transmitting circuit and the receiving circuit are connected via a wireless connection.

[0124] It should be emphasized that the transmitting circuit may also be disposed in the second housing, and the receiving circuit may be disposed in the first housing provided with the counting circuit.

[0125] In actual use, the detection module can transmit the piezoelectric signal to the transmitting module, and the transmitting module can send the voltage value of the piezoelectric signal to the receiving circuit. The receiving circuit can generate a piezoelectric signal corresponding to the voltage value and transmit it to the comparison module for comparison, which is convenient for user use.

[0126] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
