[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples.

[0035] Reference below Figures 1-8 The following describes a grip ball 100 according to an embodiment of the present invention.

[0036] like Figures 1-8 As shown, the grip ball 100 according to an embodiment of the present invention includes: a housing 10 and a detection device 20. The housing 10 is formed with a cavity 11, and the detection device 20 is disposed in the cavity 11. A pressure sensor 21 is also disposed around the outer wall of the detection device 20. Here, "surrounding" means that the pressure sensor 21 can be an integrated annular structure sleeved on the outer wall of the detection device 20, or the pressure sensor 21 can be strip-shaped and the strip-shaped pressure sensor 21 is wrapped around the outer wall of the detection device 20. When the grip ball 100 is in use, the pressure sensor 21 will contact the inner wall of the outer shell after deformation. In this way, when the outer shell 10 is not deformed, the pressure sensor 21 may be in contact with the inner wall of the outer shell or not in contact with the inner wall of the outer shell. When the pressure sensor 21 is in contact with the inner wall of the outer shell, the outer shell 10 will squeeze the pressure sensor 21 once it is deformed, which makes the grip ball 100 more sensitive to pressure detection. When the pressure sensor 21 is not in contact with the inner wall of the outer shell, the pressure sensor 21 will not be initially subjected to force after the detection device 20 is set in the cavity 11. Pressure detection will only be performed when the outer shell 10 is deformed, which makes the grip ball less susceptible to slight pressure. Preferably, in this embodiment, the pressure sensor 21 is in contact with the inner wall of the outer shell. When the user holds the grip ball 100 and applies force, the outer shell 10 will be deformed by pressure and squeeze the pressure sensor 21. In this way, when the pressure sensor 21 is squeezed, pressure data can be obtained, thereby making the grip ball 100 more sensitive to pressure detection.

[0037] Among them, the pressure sensor 21 in the present application is constructed as an integrated annular structure or a strip structure, so that the pressure sensor 21 in the present application can perform pressure measurement as a whole. Compared with the point pressure sensor in the related technology, the detection range is larger. When the grip ball using a point pressure sensor realizes the detection range in the present application, multiple point pressure sensors need to be set up. In this way, the probability of failure of the grip ball is higher and the installation is more troublesome. The pressure sensor 21 in the present application is easier to install and has a lower failure rate.

[0038] Furthermore, when the surrounding pressure sensor 21 detects pressure, even if multiple pressures act on different positions of the pressure sensor 21 at the same time, the pressure sensor 21 will directly obtain a single pressure data, so that the grip data obtained by the grip ball 100 will not jump. In the prior art, the grip ball uses multiple pressure sensors for measurement. When multiple pressures act on different pressure sensors at different positions, the grip data obtained by the grip ball still requires an analysis and calculation process. That is to say, compared with the prior art in which different pressure sensors are set at multiple points, the pressure data collection and analysis efficiency of this application is higher, the pressure monitoring and analysis cost is low, and the detection accuracy of the pressure sensor of this application is higher and more sensitive.

[0039] Exemplarily, when the pressure sensor 21 is constructed as a flexible thin film capacitive sensor, when it is squeezed and deformed, its capacitance value will change, thereby measuring and obtaining pressure data. When the flexible thin film capacitive sensor is subjected to different pressures at different positions, the pressure sensor 21 will deform at multiple locations. In this way, there will be capacitance changes at the places where the pressure sensor 21 is deformed, that is, the data measured by the pressure sensor 21 is the sum of the capacitance changes, that is, when the pressure sensor 21 is subjected to multiple pressures, it can directly derive the sum of the multiple pressures without further analysis and calculation, thereby making the grip ball 100 more sensitive when performing pressure detection.

[0040] In one embodiment, the pressure sensor 21 can be constructed in a strip shape. When it is arranged around the outer wall of the detection device 20, it can be fixed to the outer wall of the detection device 20 by adhesive. At this time, the part where the inner wall of the outer shell 10 and the pressure sensor 21 are against each other can be regarded as a nearly cylindrical curved surface. In this way, after the detection device 20 is assembled in the outer shell 10, the pressure sensor 21 is in closer contact with the inner wall of the outer shell 10, so that when the outer shell 10 is deformed, it can directly act on the pressure sensor 21, thereby making the grip ball 100 more sensitive during detection.

[0041] Among them, the shell 10 is made of a flexible deformable material, such as silicone, rubber, silicone rubber, polyurethane (TPU), thermoplastic elastomer (TPE), polyvinyl chloride (PVC), polyisobutylene (PIB), etc., so that the shell 10 is more likely to deform when subjected to pressure, thereby squeezing the pressure sensor 21 and enabling it to detect the user's grip force.

[0042] In some embodiments, as Figure 8 As shown, the detection device 20 includes: a housing 22, a PCBA 23, and a battery 24. The housing 22 has a cavity that can accommodate the PCBA 23 and the battery 24. The battery 24 can power the detection device 20, so that both the PCBA 23 and the pressure sensor 21 can be powered to ensure their normal operation. The charging port 231 provided on the PCBA 23 can power the battery 24 through an external power supply device, thus ensuring that the battery 24 can be replenished when it is out of power. The switch 232 can control the opening and closing of the detection device 20. At the same time, the PCBA 23 is also in communication with the pressure sensor 21, so that the pressure data measured by the pressure sensor 21 can be transmitted to the detection device 20 for the grip ball 100 to obtain grip data.

[0043] Furthermore, the shell 22 can be configured to include an upper shell 221 and a lower shell 222. After the upper shell 221 and the lower shell 222 are matched, a accommodating cavity will be formed therein, and the PCBA 23 and the battery 24 are both located in the accommodating cavity. In this way, the detection device 20 is set in the cavity 11 without occupying additional space, and the PCBA 23 and the battery 24 are not easily contacted with the outside world, thereby avoiding external damage to the PCBA 23 and the battery 24.

[0044] Exemplarily, the battery 24 is electrically connected to the detection device 20, so that the entire detection device 20 can be powered by the battery 24 and can operate normally. In this way, the pressure sensor 21 can transmit the pressure data to the detection device 20 after detecting the pressure, and the detection device 20 also has a communication module, so that the detection device 20 can transmit the pressure data to the terminal device through the communication module, thereby obtaining grip strength data. At the same time, a charging port 231 and a switch 232 are provided on PCBA23. When the battery 24 is out of power, the battery 24 can be charged through the charging port 231 of PCBA23, and the switch 232 can control the opening and closing of the detection device 20. In this way, the grip ball 100 can turn off the detection device 20 when it is not needed to save power, thereby increasing the usage time of the grip ball 100.

[0045] The detection device 20 also has a recording module, so that the grip ball 100 can also record the number and time of the user's exercise, and can send it to the terminal device through the communication module.

[0046] In some embodiments, as Figure 1-Figure 5 As shown, a detection area 12 is formed on the surface of the shell 10, and the detection area 12 corresponds to the area projected on the surface of the shell 10 by the pressure sensor 21. In this way, when the grip ball 100 performs grip strength detection, it only needs to press the detection area 12 to obtain grip strength data. The pressure sensor 21 in this application is constructed as an integrated annular structure or a strip structure and is arranged around the outer wall of the detection device 20. In this way, the effective detection area 12 in this application is larger than the effective detection area of ​​the grip ball using a point sensor in the prior art, thereby making the grip strength detection performance better.

[0047] In some embodiments, a plurality of protrusions 14 are arranged at intervals on the surface of the housing 10 , so that the plurality of protrusions 14 arranged on the surface of the housing 10 can massage the user's hands.

[0048] It should be noted that there are various situations when multiple protrusions 14 are provided on the surface of the shell 10. For example, only part of the surface of the shell 10 is provided with multiple protrusions 14, so that the user can perform targeted massage when using the grip ball 100. For example, multiple protrusions 14 are only provided in the area facing the palm of the user, so that the palm of the user can be massaged when using the grip ball 100. Furthermore, multiple protrusions 14 can be provided at intervals in the detection area 12 of the shell 10, so that the user's hands can be massaged while performing grip strength testing, or multiple protrusions 14 are provided throughout the surface of the shell 10, so that the grip ball 100 can also be massaged when not performing grip strength testing, thereby improving the versatility of the grip ball 100.

[0049] Of course, the protrusions 14 may not be provided on the surface of the shell 10, that is, the surface of the shell 10 is a smooth surface, so that the grip ball 100 will not massage the user's hands when holding it.

[0050] Preferably, the protrusions 14 can also be arranged throughout the area of ​​the shell 10 excluding the openings, so that when the grip ball 100 in this embodiment is not needed for grip strength detection, the structure of the protrusions 14 can also be used to massage the hands, thereby increasing the versatility of the grip ball 100 in this embodiment.

[0051] Furthermore, the protrusion 14 can be constructed as a cone, that is, the bottom surface of the cone is located in the detection area 12 on the surface of the shell 10, and the apex of the cone is facing away from the surface of the shell 10. In this way, the cone is more stable when fixed on the shell 10, and the cone has a better effect in massaging the user's hands.

[0052] In some embodiments, as Figure 4As shown, the shell 10 has an opening, and the opening is oriented in the same direction as the charging port 231. The direction of the opening formed on the shell 10 is the same as the direction of the charging port 231 of the PCBA 23. In this way, after the detection device 20 is placed in the shell 10, it can contact the charging port 231 through the opening, so that the grip ball 100 can be charged through the charging port 231 when it is out of power, so that the grip ball 100 can be used for a long time.

[0053] In some embodiments, as Figure 4 As shown, the housing 10 is also formed with a control area 13, which is oriented in the same direction as the switch 232. The switch 232 of the PCBA 23 is oriented in the same direction as the control area 13. Pressing the control area 13 triggers the switch 232, thereby turning the detection device 20 on and off. This allows the grip ball 100 to be turned off when not in use, thereby extending its usability.

[0054] Among them, the charging port 231 and the switch 232 set on the PCBA23 can be set on the same side. At this time, the opening and the control area 13 on the shell 10 are also set on the same side, that is, there is a control area 13 around the opening, or the control area 13 and the opening at least partially overlap, so that the switch can be directly triggered when the end cover is removed to expose the charging port, or the charging port 231 and the switch 232 are not set on the same side, so that the opening and the control area 13 on the shell will be arranged according to the orientation of the charging port 231 and the switch 232. Preferably, the charging port 231 and the switch 232 are respectively provided on both axial sides of the detection device 20 (the axial direction is the axial direction of the surrounding pressure sensor 21). In this way, the opening and the control area 13 on the shell 10 will not affect the detection area 12, and at the same time can improve the aesthetics of the grip ball 100.

[0055] Furthermore, the control area 13 formed on the shell 10 is not provided with a protrusion 14, that is, the control area 13 is a smooth surface, which makes it easier to press the control area 13 and trigger the switch 232, thereby making it easier to open or close the grip ball 100.

[0056] In some embodiments, as Figure 3-Figure 4 As shown, the grip ball 100 further includes an end cap 15 adapted to fit within the opening. When fitted with the opening, the end cap 15 can shield the charging port 231 of the detection device 20, thereby protecting the charging port 231 from moisture, dust, and the like, which could potentially affect or damage the charging port.

[0057] In some embodiments, as Figure 4As shown, the end cap 15 is provided with a first clip 224 on the side facing the housing 10, and a second clip 16 is formed on the end of the housing 22 on the same side as the charging port 231. The second clip 16 engages with the first clip 224. The engagement of the first clip 224 and the second clip 16 secures the end cap 15 to the housing 10, thereby preventing the end cap 15 from falling off the opening after mating with the opening, thereby enabling the end cap 15 to better protect the charging port 231.

[0058] For example, the first clamping member 224 can be configured as a socket, and the second clamping member 16 can be configured as a conical head. Thus, when the first clamping member 224 and the second clamping member 16 are engaged, the conical head extends into and engages within the socket, thereby preventing the end cap 15 from falling out of the opening and better protecting the charging port 231 of the detection device 20. The conical head is made of an elastic material; the diameter of the socket is smaller than the maximum diameter of the conical head; and the conical head is inserted into the interior of the housing 22 through the socket.

[0059] Furthermore, a fixing protrusion is provided on the end cover 15. When the end cover 15 cooperates with the opening, the fixing protrusion will extend into the charging port 231 of the detection device 20, which can assist in fixing the end cover 15, so that the end cover 15 can be better fixed at the opening. At the same time, the fixing protrusion can also protect the charging port 231, so that the end cover 15 can better protect the charging port 231.

[0060] In other embodiments, a boss is formed on one end of the shell 22 facing the charging port 231, and at least a portion of the boss extends into the opening, while a groove that cooperates with the boss is formed on the side of the end cover 15 facing the outer shell 10. In this way, when the end cover 15 cooperates with the opening, the boss on the shell 22 cooperates with the groove on the end cover 15 to ensure the fixing effect of the end cover 15, so that the end cover 15 can better protect the charging port 231 of the detection device 20.

[0061] In some embodiments, the pressure sensor 21 is configured as a flexible thin-film capacitive pressure sensor. The flexible thin-film capacitive pressure sensor itself is highly flexible, making it easier to surround the outer wall of the detection device 20, thereby facilitating the overall assembly of the grip ball 100.

[0062] In some embodiments, as Figure 7As shown, the pressure sensor 21 has a first end and a second end along its length. The first and second ends are close to each other so that the pressure sensor 21 bends and wraps around the outer wall of the detection device 20, with a gap between the first and second ends. After the pressure sensor 21 is constructed in a strip shape, it has a first end and a second end along its length. In this way, when the pressure sensor 21 is installed on the outer wall of the detection device 20, the first and second ends along its length are close to each other, so that the pressure sensor 21 can be installed around the outer wall of the detection device 20. At the same time, after the pressure sensor 21 is installed around the outer wall of the detection device 20, a gap is provided between the first and second ends. This can prevent the formation of inductive capacitance between the ends and ensure the normal use of the pressure sensor 21.

[0063] It should be noted that the pressure sensor 21 will deform to a certain extent during installation or use with the grip ball. The gap between the first and second ends provides sufficient deformation space for the pressure sensor 21, thereby ensuring the normal operation of the pressure sensor 21. That is, the pressure sensor 21 will be pressed and deformed during normal use or installation. Such a gap provides sufficient deformation space for the pressure sensor 21, thereby ensuring the structural stability of the pressure sensor 21. This gap prevents the ends of the installed pressure sensor 21 from touching, avoiding the occurrence of induced capacitance in the pressure sensor 21 and preventing interference from the induced capacitance during the acquisition of pressure data.

[0064] In some embodiments, the pressure sensor 21 includes a stacked electrode layer 1, a dielectric layer, and an electrode layer 2; the dielectric layer is an elastically deformable porous structure. The dielectric layer is sandwiched between the electrode layer 1 and the electrode layer 2. When the pressure sensor 21 is squeezed, the dielectric layer deforms. This deformation changes the capacitance of the pressure sensor, allowing pressure data to be obtained by measuring this change in capacitance.

[0065] Specifically, the dielectric layer is an elastically deformable porous structure layer. By adopting a porous structure dielectric layer, when the dielectric layer is squeezed, the thickness change of the porous structure dielectric layer is more obvious. From the capacitance formula C=εS / 4πkd, it can be seen that the introduction of the porous structure can cause the distance d between the two poles to change more obviously, thereby improving the response sensitivity of the flexible film pressure sensor, and further improving the detection accuracy of the pressure flexible capacitive film pressure sensor, which can improve the detection accuracy of the grip ball 100.

[0066] Among them, when the dielectric layer is constructed as a porous structure layer, there is air in the pores, and when the dielectric layer is squeezed, the air will be discharged from the pores, which will also affect the relative dielectric constant of the dielectric layer, thereby making the detection accuracy of the flexible thin film pressure sensor higher.

[0067] Furthermore, electrode layer one and electrode layer two can be made of conductive fabrics, such as conductive cloth, conductive carbon cloth, etc., so that electrode layer one and electrode layer two themselves also have good flexibility, making it easier to surround the pressure sensor 21 and arrange it on the outer wall of the detection device 20. The conductive fabric has good toughness and is not easily affected by external pulling forces, which may cause its conductivity to be destroyed, thereby ensuring its good structural stability and conductivity.

[0068] In some embodiments, conductive fillers are also dispersed in the dielectric layer. By setting the conductive fillers in the dielectric layer, the dielectric constant of the dielectric layer can be improved. At the same time, when the dielectric layer is compressed, the distance between the conductive filler particles is compressed, and the dielectric constant is further improved, so that the capacitance value becomes obvious, which is beneficial to the monitoring of the sensor, thereby making the measurement accuracy of the pressure sensor 21 higher.

[0069] In some embodiments, an insulating layer is further provided between electrode layer 1 and the dielectric layer or between dielectric layer 2 and the dielectric layer. By introducing the insulating layer, the risk of capacitor breakdown can be reduced. At the same time, the insulating layer is only provided between electrode layer 1 and the dielectric layer, so that the overall structure of the pressure sensor 21 is simple and the cost is low. While reducing the risk of breakdown, it also reduces the problem of reduced capacitance caused by increasing the distance between electrode layer 1 and electrode layer 2 due to the provision of too many insulating layers (the capacitance value is related to the distance between the two electrodes), thereby ensuring the sensitivity of the pressure sensor 21.

[0070] In some embodiments, an insulating layer is provided between electrode layer 1 and electrode layer 2 and the dielectric layer. The insulating layer is provided between electrode layer 1 and the dielectric layer and between electrode layer 2 and the dielectric layer, which greatly reduces the breakdown risk.

[0071] Preferably, in this embodiment, an insulating layer is provided between electrode layer 1 and the dielectric layer or between electrode layer 2 and the dielectric layer. This can reduce the risk of breakdown while avoiding the problem of reduced capacitance caused by increasing the distance between electrode layer 1 and electrode layer 2 due to the provision of too many insulating layers, thereby improving the sensitivity of the pressure sensor 21 and further improving the detection sensitivity of the grip ball 100.

[0072] Among them, the conductive filler includes at least one of a non-metallic conductive filler, a conductive oxide filler and a semiconductor filler. When the conductive filler adopts a non-metallic conductive filler, it is selected from at least one of carbon nanotubes, graphene, carbon powder, PEDOT polymer, polyaniline (PANI), polythiophene (PTh), polystyrene sulfonate (PSS) and polycarbazole (PCz). When the conductive filler adopts a conductive oxide filler, it is selected from at least one of copper oxide, iron oxide, tin oxide, tungsten oxide and manganese oxide. When the conductive filler adopts a semiconductor filler, it is selected from at least one of silicon, germanium, cadmium selenide, gallium arsenide, germanium arsenide and gallium nitride.

[0073] The material of the insulating layer is at least one of PMMA, PI, PE, PET, PPS, PU, ​​FEP, PFA, ETFE, PEEK, polysilazane, alumina, quartz, organic polymer, polycarbonate, silicone resin, fluoride material, rubber, ceramic, high molecular polymer and silicon dioxide.

[0074] In some embodiments, as Figure 8 As shown, reinforcing ribs 223 are formed in the upper shell 221 and the lower shell 222. It should be noted that the reinforcing ribs 223 formed in the upper shell 221 and the lower shell 222 can increase the structural strength of the upper shell 221 and the lower shell 222, thereby improving the overall structural stability of the shell 22. At the same time, the reinforcing ribs 223 can support the PCBA 23 and the battery 24 in the detection device 20, so that the PCBA 23 and the battery 24 are not easily shaken after being placed in the accommodating cavity of the shell 22, thereby making it difficult for the grip ball 100 to produce errors during use.

[0075] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0076] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
