In order to further improve the interactive interest of desktop boxing ball, the prior art will arrange a sensor on the desktop boxing ball to detect and obtain the hitting state and effect of the user. For example, an acceleration sensor (G-sensor) is arranged in the ball body, which is used to measure the acceleration of the ball body when it is hit.

DETAILED DESCRIPTION

[0041] The specific embodiments of the utility model are described in detail below in combination with the drawings.

[0042] As Figures 1-8 shown, the utility model discloses a boxing ball in the embodiment, aims at making improvement to the force measuring scheme in prior art, realizes the measurement of the hitting power value produced by the all-around hitting of user, reduces the measurement cost, improves the measurement precision.

[0043] The force measurement scheme for the desktop punching ball in the prior art usually adopts two forms as follows: the first scheme adopts an acceleration sensor to measure the hitting force value, but due to the non-linear measurement and drift of the acceleration sensor, in order to ensure the accuracy of the measurement, a complex algorithm is required for compensation, resulting in an increase in the cost of control measurement; the second scheme adopts a pressure sensor arranged in the ball body to detect the pressure applied on the ball body when the user hits, however, since the installation position of the pressure sensor is fixed, for example, the pressure sensor is installed in the interlayer of the ball body, due to the limitation of the manufacturing cost, the number of pressure sensors is usually limited to 2-3, resulting in a limited detection area on the ball body for detecting the hitting force, making it difficult to effectively measure and feedback the hitting in all directions, thereby limiting the hitting direction of the user, so that the user can only hit the specific area on the ball body in the appropriate hitting direction to obtain effective feedback of the hitting force value, and it is difficult to measure the hitting force value generated by the user in all directions.

[0044] [Desktop punching ball]

[0045] As Figure 1 combined Figure 2 indicated, a desktop punching ball includes a ball body 1, a base 2, a force display device 3, and a first connecting rod 6 and a second connecting rod 7 as shown in Figure 5 The force display device 3 is located between the ball body 1 and the base 2, and is used to display the feedback force value of hitting the desktop punching ball. Among them, the ball body 1 selects a conventional punching ball, and the base 2 selects a suction cup.

[0046] As Figure 3 combined Figure 4 indicated, the force display device 3 includes a shell 31, a main control module, a display screen 32, a light bar 33, and a force measurement structure 34 as shown in Figure 5 Among them, the main control module is not shown in the figure. The shell 31 is sleeved on the outside of the force measurement structure 34. The display screen 32 and the light bar 33 are both installed on the inner wall of the shell 31. The side wall of the shell 31 is provided with a first window 35 for exposing the display surface of the display screen 32, and a second window 36 for displaying the light bar 33. The main control module is used to drive the display screen 32 to display the force value of hitting the desktop punching ball, and is used to drive the light bar 33 to display the interval of the force value of hitting the desktop punching ball.

[0047] As Figure 6 indicated, the force measurement structure 34 includes a force measurement frame 341 and a pressure sensor 342. As Figure 7As shown, the force measuring stand 341 includes a first mounting portion 3411 for connecting the ball 1, a second mounting portion 3412 for connecting the base 2, and a connecting unit. The first mounting portion 3411 is connected to the second mounting portion 3412 through the connecting unit. The connecting unit includes a plurality of connecting columns 3413 arranged in parallel. One end of the connecting column 3413 is connected to the first mounting portion 3411. The other end of the connecting column 3413 is connected to the second mounting portion 3412. In combination Figure 5 As shown, the first mounting portion 3411 of the force measuring stand 341 is connected to the ball 1 through the first connecting rod 6. The second mounting portion 3412 of the force measuring stand 341 is connected to the base 2 through the second connecting rod 7.

[0048] As shown Figure 7 As shown, the side wall of the connecting column 3413 is provided with a detection area. The pressure sensor 342 is installed on the detection area. The output end of the pressure sensor 342 is connected to the input end of the main control module through an amplification circuit. The pressure sensor 342 corresponds to the number of connecting columns 3413. In this way, a pressure sensor 342 is installed on each connecting column 3413, realizing multi-point monitoring and being able to fully capture the pressure changes in different directions and positions, further improving the comprehensiveness and accuracy of measurement, realizing the measurement of the hitting force value generated by the user's all-around hitting, reducing the measurement cost, and improving the measurement accuracy.

[0049] The pressure sensor 342 measures force by using the structural strain-stress relationship. When the user hits the ball 1, the hitting force is conducted along the ball 1, the first connecting rod 6, the force measuring stand 341, and the second connecting rod 7 to the base 2. The hitting force causes the connecting column 3413 in the force measuring stand 341 to deform during the conduction process. The pressure sensor 342 detects the deformation and converts it into an electrical signal. The pressure sensor 342 can be selected according to the needs of the sensor with piezoresistive effect or piezoelectric effect or capacitive effect.

[0050] For example, the pressure sensor 342 selects a piezoresistive strain gauge. The piezoresistive strain gauge is pasted on the connecting column 3413. When the connecting column 3413 is subjected to external force, the strain gauge will deform, causing the resistance value to change. By measuring the change in resistance value, the size of the applied force can be calculated.

[0051] [Force measuring structure]

[0052] As shown Figure 6 In combination Figure 7 As shown, a force measuring structure 34 includes a force measuring stand 341 and a pressure sensor 342. The force measuring stand 341 is used to connect the ball 1 and the base 2. The force measuring stand 341 defines a plurality of detection areas for installing the pressure sensor 342.

[0053] The pressure sensor 342 is arranged on the detection area, and each detection area is provided with a corresponding pressure sensor 342.

[0054] The force frame 341 is arranged to bear and transmit the hitting force of the hitting ball 1, and the pressure sensor 342 converts the deformation into an electrical signal.

[0055] For example, the internal sensitive element of the pressure sensor 342 can be selected from a metal strain gauge, a semiconductor strain gauge, a piezoelectric element, a capacitive element, a resistive element, and an optical fiber sensing element.

[0056] Therefore, no matter from which angle and position the user hits the punching ball, the hitting force of the punching ball will be transmitted from the ball 1 to the force frame 341, and the force frame 341 will be deformed under the action of the hitting force. The internal sensitive element of the pressure sensor 342 detects the deformation and converts it into an electrical signal, thereby realizing the measurement of the hitting force, and realizing the measurement of the hitting force of the user hitting the punching ball from all directions, reducing the measurement cost and improving the measurement accuracy.

[0057] As shown in Figure 7 The force frame 341 includes a first mounting portion 3411 for connecting the ball 1, a second mounting portion 3412 for connecting the base 2, and a connecting unit. The first mounting portion 3411 is connected to the second mounting portion 3412 through the connecting unit. In this way, the force frame 341 is composed of the first mounting portion 3411, the second mounting portion 3412 and the connecting unit, and the overall structure is stable. The first mounting portion 3411 connects the ball 1, and the second mounting portion 3412 connects the base 2, ensuring that the force frame 341 remains stable when subjected to external force impact, and does not shake or shift, thereby improving the reliability of the measurement data.

[0058] The force frame 341 is made of a material with elastic deformation. For example, the force frame 341 is made of plastic with elastic deformation and is integrally injection molded, which is beneficial to reduce the number of molds and reduce the mold cost. For small batch production requirements of dozens of pieces, the force frame 341 can also be integrally formed by 3D printing processing, further saving the mold cost.

[0059] In order to further reduce the difficulty of mold design, the force frame 341 can also be designed in a split structure. For example, the first mounting portion 3411, the second mounting portion 3412 and the connecting unit are separately molded and injection molded, and compared with the above-mentioned integrally injection molded processing method, the structure of the mold is simpler, which is beneficial to improve the processing precision.

[0060] For the split structure design of the force measuring stand 341, the processing technology needs to increase the corresponding assembly process. For example, the first mounting part 3411, the second mounting part 3412 and the connecting unit are assembled by fasteners or are assembled by using a gluing connection. In order to further reduce the assembly difficulty of the force measuring stand 341, the first mounting part 3411 and the second mounting part 3412 are both provided with a limiting structure for assisting the positioning of the connecting unit. The limiting structure is selected from a limiting groove or a limiting hole.

[0061] In order to ensure the overall structural strength of the force measuring stand 341, according to the different selected materials, the thicknesses of the first mounting part 3411 and the second mounting part 3412 are both 6mm-10mm.

[0062] As shown in Figure 7 , the first mounting part 3411 and the second mounting part 3412 are both provided with a connecting through hole. The connecting through hole is used for penetrating the first connecting rod 6 and the second connecting rod 7, so as to facilitate the assembly of the force measuring stand 341 with the sphere 1 and the base 2. For example, the first connecting rod 6 and the second connecting rod 7 are both selected as threaded rods. The threaded rods form the assembly structure of the force measuring stand 341 by being screwed with nuts, or the connecting through hole is provided with an internal thread matched with the threaded rod, and the threaded rod is directly screwed in the connecting through hole to form the assembly structure of the force measuring stand 341.

[0063] As shown in Figure 7 , the connecting unit includes a plurality of parallel arranged connecting columns 3413. One end of the connecting column 3413 is connected with the first mounting part 3411, and the other end of the connecting column 3413 is connected with the second mounting part 3412. In this way, a pressure sensor 342 is installed on each connecting column 3413, realizing multi-point monitoring and being capable of fully capturing the pressure changes in different directions and positions, thereby further improving the comprehensiveness and accuracy of measurement. In addition, the interval space formed between adjacent connecting columns 3413 facilitates reserving an assembly space for the force measuring stand 341, thereby further reducing the assembly difficulty.

[0064] As shown in Figure 8 , the length direction of the connecting column 3413 is defined as the direction perpendicular from the first mounting part 3411 to the second mounting part 3412, the thickness direction of the connecting column 3413 is perpendicular to the detection area, and the width direction of the connecting column 3413 is perpendicular to the length direction and the thickness direction.

[0065] For the length design of the connecting column 3413, considering the structural size of the fist ball and the outer size of the pressure sensor 342, the length of the connecting column 3413 is at least greater than the length of the pressure sensor 342. For example, the length of the connecting column 3413 is 40mm-60mm. The detection area is located in the middle of the connecting column 3413, and the pressure sensor 342 is assembled on the detection area. A certain assembly space is reserved in the length direction of the connecting column 3413, thereby facilitating the assembly of the force frame 341 with the first connecting rod 6 and the second connecting rod 7.

[0066] For the width design of the connecting column 3413, mainly considering the outer size of the pressure sensor 342, the width of the connecting column 3413 is 12mm-20mm.

[0067] For the thickness design of the connecting column 3413, both the support strength of the force frame 341 and the better elastic deformation are ensured. According to the different materials selected by the force frame 341, the thickness of the connecting column 3413 is 2mm-4mm.

[0068] For the interval space formed between adjacent connecting columns 3413, the assembly space of the force frame 341 with the first connecting rod 6 and the second connecting rod 7 is ensured, and the nut and the fastening nut are placed to the inside of the force frame 341.

[0069] If the connecting through hole on the first mounting portion 3411 and the second mounting portion 3412 is a threaded hole, then the nut assembly is not needed, the interval space between the connecting columns 3413 can be further reduced, and even the interval space reserved between the adjacent connecting columns 3413 can be cancelled.

[0070] According to some preferred embodiments of the utility model, as shown in Figure 7 The connecting column 3413 is provided with a limiting boss 3414. The limiting boss 3414 is located on one side of the detection area. In this way, the limiting boss 3414 is used for auxiliary positioning of the installation of the pressure sensor 342, which is beneficial to improve the installation position accuracy of the pressure sensor 342, and further improve the measurement accuracy.

[0071] From the role of the limiting boss 3414, the limiting boss 3414 can be simplified as a mark line on the surface of the connecting column 3413, and the mark line is used for auxiliary positioning of the side edge of the pressure sensor 342. A plurality of mark lines can be designed on the connecting column 3413, which is used for the assembly auxiliary positioning of the pressure sensor 342 of different sizes.

[0072] In order to further improve the installation stability of the pressure sensor 342, as shown in Figure 7As shown, the two sides of the limiting boss 3414 are provided with a stop rib 3416. The stop rib 3416 extends towards the detection area. In this way, the stop rib 3416 is used to guide and limit the side wall of the pressure sensor 342, which is conducive to further improving the installation stability of the pressure sensor 342.

[0073] In order to further improve the sensitivity of the force measuring structure 34, as shown in the figure, Figure 7 As shown, a groove 3415 is arranged on the detection area. The groove 3415 is perpendicular to the arrangement of the connecting column 3413. In this way, the groove 3415 makes the connecting column 3413 form a partial gap in the detection area, which is conducive to reducing the difficulty of deformation of the connecting column 3413, and further improving the sensitivity of the force measuring structure 34.

[0074] Among them, the groove 3415 is equivalent to a thinning structure on the connecting column 3413. According to the connecting column 3413 structure designed by different materials and different thicknesses, the groove 3415 should have a corresponding structure design.

[0075] For example, when the thickness of the connecting column 3413 is 3mm or more, the connecting column 3413 has good support strength, as shown in the figure, Figure 8 The groove 3415 can be designed to penetrate the width direction of the connecting column 3413, and the cross section of the groove 3415 can be selected as a circular arc or a V shape. The depth of the groove 3415 is 0.3mm-1mm. When the thickness of the connecting column 3413 is less than 3mm, in order to ensure the support strength of the connecting column 3413, the groove 3415 can be arranged in a dot array.

[0076] In combination with the structure design of the limiting boss 3414 and the thinning design of the connecting column 3413, the detection area for installing the pressure sensor 342 can also be designed to be sunk as a whole on the connecting column 3413, so that the pressure sensor 342 forms an embedded mounting structure on the connecting column 3413.

[0077] As shown in the figure, Figure 3 The force measuring frame 341 is provided with three pressure sensors 342, which are arranged in a triangle along the central axis of the force measuring frame 341, so as to capture the pressure changes in different directions and positions on the connecting column 3413. According to the detection accuracy or sensitivity requirements, a proper number of pressure sensors 342 are selected, and the corresponding number of connecting columns 3413 are arranged in the structure of the force measuring frame 341. A plurality of pressure sensors 342 can be arranged in a circle along the central axis of the force measuring frame 341. Among them, the number of pressure sensors 342 is preferably 3-6.

[0078] [Force display device]

[0079] As shown in the figure, Figure 1As shown, a force display device 3 for displaying the force value of hitting the punching ball, comprising the force measuring structure 34 and the shell 31 sleeved outside the force measuring structure 34, the shell 31 is defined with a first display area and a second display area; the display screen 32 arranged in the first display area; the light bar 33 arranged in the second display area.

[0080] The main control module in the shell 31, the main control module is used for driving the display screen 32 to display the force value of hitting the punching ball, and is used for driving the light bar 33 to display the interval of the force value of hitting the punching ball. The output end of the pressure sensor 342 is connected with the input end of the main control module through the amplification circuit.

[0081] For example, the display screen 32 and the light bar 33 are both installed on the inner wall of the shell 31. The sidewall of the shell 31 is provided with a first window 35 for exposing the display surface of the display screen 32, and a second window 36 for displaying the light bar 33.

[0082] In the embodiment of the utility model, the force display device 3 in the desktop punching ball realizes the collection of the hitting force value generated by the user hitting in all directions through the force measuring structure 34, amplifies and transmits the output signal of the pressure sensor 342 to the main control module, and feeds back the hitting result in two ways of the display screen 32 and the light bar 33, realizes the real-time detection and display of the hitting force. The display screen 32 and the light bar 33 are exposed through the first window 35 and the second window 36 respectively, and the visual display of the clear force value and the force interval is provided. The display screen 32 is used to represent the force value of the user hitting, and the light bar 33 represents the force interval through different colors and / or brightness, and provides more intuitive visual representation.

[0083] For example, the display screen 32 can select a variety of display devices such as nixie tube, LED, LCD, etc., and the embodiment takes 888 nixie tube as an example. When the pressure sensor 342 detects the trigger force, the nixie tube displays the peak value of the hitting force. If continuous hitting, the maximum peak force of continuous hitting is displayed. Among them, the trigger force of the pressure sensor 342 is 2Kg, and the maximum force is 250Kg. In this example, the representation of the force value can use Lb or Kg as a unit to display to the user.

[0084] As an example, the light bar 33 is arranged below the display screen 32, and the light bar 33 is configured with multiple colors / brightness, and the force is divided into corresponding intervals. In this example, four colors are taken as an example, for example, the detected hitting force is measured in Kg, 10KG-50Kg is green, 51-100Kg is yellow, 101-150Kg is blue, and 151-200Kg is red. In this way, the user can quickly and intuitively understand the hitting effect, so that the force feedback is more rich and diversified.

[0085] As Figure 2 Combining Figure 1 It is shown that the ball 1 and the force display device 3 are also provided with a protective cover 4. The protective cover 4 is connected with the shell 31. In this way, the protective cover 4 is used to form a visual transition between the ball 1 and the force display device 3 on the one hand, and to shield the first connecting rod 6 inside on the other hand, avoiding the user from hitting the first connecting rod 6, and being beneficial to the protection of the user.

[0086] As Figure 5 Combining Figure 2 It is shown that the shell 31 is arranged between the ball 1 and the base 2. The end cover 39 is arranged at the end of the shell 31 close to the ball 1. The end cover 39 is connected with the shell 31 through fasteners. The mounting hole 391 is arranged on the end cover 39. The end cover 39 is used to shield the end of the shell 31, and further shield the components inside the shell 31. In addition to being used for the first connecting rod 6 to pass into the shell 31, the mounting hole 391 is also used to limit the first connecting rod 6 in the radial direction, which is beneficial to avoid excessive external force to cause the measured force value to exceed the measurement range of the pressure sensor 342.

[0087] As Figure 5 It is shown that the decorative strips 5 are arranged on the side wall of the shell 31 close to the base 2. A plurality of decorative strips 5 are arranged in a circular shape along the axis of the shell 31, which is used to decorate the shell 31.

[0088] In order to further improve the portability, a rechargeable battery is arranged in the shell 31. As ​ It is shown that the charging socket 37 is arranged on the side wall of the shell 31. For example, a 500mAh rechargeable battery is arranged in the shell 31, and a TYPE-C charging port is arranged at an appropriate position of the shell 31, which is used to charge the battery.

[0089] In order to further enrich the use function of the desktop boxing ball, the main control module is also connected with a recording module.
