Combined with a pressure sensor and transmission plate structure, this ensures the accuracy and stability of the triggering force. The fit between the frame body and the pool wall is adjusted by an adjustment component.
This improves the accuracy and reliability of the triggering force of the swimming timing device, reduces the processing difficulty and cost, and avoids false triggering and suspension problems, thus ensuring the stability and service life of the device.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, and in particular to a swimming timing sensor module and a swimming timing trigger device. Background Technology
[0002] A swimming timing trigger device is a device used to initiate timing during swimming competitions. After the starting gun fires, the timing system begins timing. When the athlete reaches the finish line, they tap or press the touchpad on the timing trigger device. This triggers the two electrodes of the internal pressure sensor to close and output a switching electrical signal. Upon detecting the signal, the timing system stops, thus accurately recording the athlete's result. Due to the prestige and importance of these competitions, swimming timing trigger devices require extremely high sensitivity and reliability. Currently, in prestigious swimming events, the use of swimming timing trigger devices is almost entirely monopolized by the Swiss company Omega.
[0003] According to FINA regulations, swimming timing triggers must be activated by an external force of 2.5-4 kg. If the trigger force is less than 2.5 kg, the timing trigger may malfunction under the impact of water flow, invalidating the result. If the trigger force is greater than 4 kg, the timing trigger may fail to activate under the athlete's tapping or pressing, also invalidating the result. In youth swimming competitions, due to the relatively weak pressing and tapping force of young swimmers, trigger failures are frequent. Some manufacturers have adjusted the trigger force of the timing trigger to a lower level. When the processing precision of the sensor mounting bracket is substandard, the timing system frequently malfunctions under the impact of water flow.
[0004] Currently, existing sensor mounting brackets such as Figure 1 As shown, after one side of the mounting bracket is bent into a first folded edge using a bending machine, due to the large bending angle of the first folded edge, when the other side of the mounting bracket is bent at the same angle to form a second folded edge, the bending blade interferes with the first folded edge after bending to a certain angle. Therefore, the bending blade must be withdrawn first, and then a pressure plate is used to press the second folded edge downwards to achieve the preset bending angle. This operation not only fails to guarantee processing accuracy but also increases processing difficulty and cost. Utility Model Content
[0005] To overcome the shortcomings of the prior art, one objective of this utility model is to provide a sensor module for swimming timing, wherein the first and second folded edges on the mounting bracket can be bent in one stroke by a bending machine, which makes it easy to ensure the processing accuracy, thereby ensuring the accuracy of the triggering force, and the processing difficulty and processing cost are lower. Another objective of this utility model is to provide a swimming timing triggering device with the above-mentioned sensor module, which has high triggering stability and reliability.
[0006] One of the objectives of this utility model is achieved through the following technical solution:
[0007] A sensor module for swimming timing includes a mounting bracket, wherein:
[0008] The mounting bracket includes a base plate portion, the upper and lower sides of which are bent forward to form two first folded edges, and the first folded edges are bent outward to form a second folded edge portion; wherein, the angle at which the base plate portion is bent forward is 'a', the angle at which the first folded edges are bent outward is 'b', and a≤90°, b≤90°;
[0009] The first folded edge and the second folded edge form an elastic folded edge, which is configured to produce elastic deformation when squeezed by the touchpad to control the trigger force of the touchpad.
[0010] As an optional implementation, a pressure sensor is also included, which is disposed on the substrate portion and located between the two elastic folds; the pressure sensor includes a body portion and an elastic protrusion portion disposed on the body portion, a first electrode is provided in the body portion, and a second electrode is provided in the elastic protrusion portion; when the elastic protrusion portion is squeezed and generates elastic deformation until the first electrode contacts the second electrode, the pressure sensor is triggered.
[0011] As an optional implementation, it further includes at least one pressure plate, which is mounted on the base plate and presses and fixes the body portion on the base plate; the front end of the elastic protrusion protrudes from the pressure plate.
[0012] As an optional implementation, a transmission plate is also included, which is mounted on the base plate and located at the front end of the elastic protrusion.
[0013] The transmission plate is movable back and forth relative to the mounting bracket, and the transmission plate is configured to move backward and press the elastic protrusion when pushed by the touch panel.
[0014] As an optional implementation, a limiting sleeve is also included, which is sleeved on the outer periphery of the mounting bracket; the limiting sleeve is used to restrict the transmission plate between the two elastic folds and located in the area directly in front of the elastic protrusion.
[0015] As an optional implementation, the mounting bracket is arranged in a long strip shape; the pressure sensor, the pressure plate, the transmission plate and the limiting sleeve all extend along the length direction of the mounting bracket.
[0016] The second objective of this utility model is achieved by the following technical solution:
[0017] A swimming timing trigger device includes the aforementioned sensor module, a frame body, and several touchpads, wherein:
[0018] The main frame is installed on the pool wall and extends along the width of the pool channel.
[0019] Several of the touch panels are arranged side by side within the frame body along the width direction of the pool channel; the touch panels are movable back and forth relative to the frame body;
[0020] The sensor module is provided in at least two, and the at least two sensor modules are arranged vertically at intervals within the frame body and located behind the several touch panels.
[0021] As an optional implementation, the system also includes a mounting plate, which has a first adjustment hole extending along the width of the pool channel and a second adjustment hole extending along the length of the pool channel. One of the first adjustment hole and the second adjustment hole is connected to the frame body, and the other is connected to the pool.
[0022] As an optional implementation, it also includes a number of adjustment components disposed on the frame body. The adjustment components include at least a threaded hole opened on the rear end face of the frame body and an adjustment screw screwed into the threaded hole. When the adjustment screw is turned, the adjustment screw can move in the front-back direction until its rear end is in contact with the pool wall.
[0023] As an optional implementation, a reinforcing rib plate is also included within the frame body, the reinforcing rib plate abutting against the rear side of the sensor module.
[0024] In summary, this utility model has the following technical effects:
[0025] (1) The swimming timing sensor module of this utility model has a forward bending angle a on the upper and lower sides of the substrate and an outward bending angle b on the first folded edge, both of which are less than or equal to 90 degrees. Therefore, the first folded edge and the second folded edge can be bent into shape in one stroke by a bending machine, and the processing accuracy can be guaranteed, thereby ensuring the accuracy of the touch panel trigger force. At the same time, the processing difficulty and processing cost are lower.
[0026] (2) The swimming timing sensor module of this utility model has a pressure plate on the base plate. The pressure plate can not only press and fix the pressure sensor on the base plate, but also limit the touch plate when the touch plate drives the transmission plate to move backward and squeeze the elastic protrusion until the transmission plate abuts against the pressure plate. This prevents the touch plate from continuing to squeeze the elastic fold and causing the elastic fold to undergo plastic deformation, thereby ensuring the service life of the mounting bracket.
[0027] (3) The swimming timing sensor module of this utility model, by setting a transmission plate, when the athlete presses or pats the touch plate, the touch plate can transmit the force to the transmission plate and then to the elastic protrusion, so that the elastic protrusion is subjected to more uniform force, thereby improving the stability and reliability of triggering.
[0028] (4) The swimming timing sensor module of this utility model has an installation plate that can be moved and adjusted along the length of the pool channel and along the width of the pool channel. This can effectively absorb the error of the installation hole in the swimming pool, so that the frame body can fit better against the pool wall after installation. This avoids the problem of increased triggering force due to suspension, and also avoids the problem of reduced triggering force due to pressure from the pool wall.
[0029] (5) The swimming timing sensor module of this utility model has several adjustment components on the frame body. When the frame body is installed on the pool wall, the rear end of the frame body can be made to fit the pool wall by turning the adjustment screw in the adjustment component, thereby avoiding the gap between the rear side of the frame body and the pool wall, and thus ensuring the accuracy of the triggering force.

[0047] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0048] Example 1
[0049] See Figures 2 to 5This application discloses a swimming timing sensor module 1, which includes a mounting bracket 11 and a pressure sensor 12. The mounting bracket 11 includes a long strip-shaped base plate portion 111 extending along the width of the pool channel. The pressure sensor 12 is mounted on the front end face of the base plate portion 111. The upper and lower sides of the base plate portion 111 are bent forward at an angle α to form two first folded edges 112, and the middle of the first folded edges 112 is bent outward at an angle β to form a second folded edge 113. Both angles α and β are less than or equal to 90 degrees. The first folded edges 112 and the second folded edges 113 form an elastic edge, which is configured to produce a certain elastic deformation when pressed by a touchpad 3 to control the triggering force of the touchpad 3.
[0050] Based on the above structure, when the athlete presses or pats the touchpad 3, it can push the touchpad 3 to move backward and abut against the elastic folded edge. The elastic folded edge will produce elastic deformation after being squeezed. Then the touchpad 3 continues to move backward and abut against the pressure sensor 12. The pressure sensor 12 is triggered and outputs a switching electrical signal. After the timing system detects the signal, the timing ends, thereby recording the athlete's competition results.
[0051] In this embodiment, both angle a and angle b are 45 degrees, thereby arranging the second folded edge 113 vertically (i.e., as shown). Figure 2 (The touchpad 3 is arranged to extend vertically). When the athlete presses or pats the touchpad 3, it can move the touchpad 3 backward and abut against the second folded edge 113. Since the touchpad 3 is also arranged vertically, when it abuts against the second folded edge 113, the contact area between the two is large and the contact reliability is high.
[0052] The sensor module 1 of this utility model forms a first folded edge 112 by bending the substrate 111, and a second folded edge 113 by bending the first folded edge 112. The bending angle a of the substrate 111 and the bending angle b of the first folded edge 112 are both less than or equal to 90 degrees. Therefore, the first folded edge 112 formed by bending the substrate 111 and the second folded edge 113 formed by bending the first folded edge 112 can both be formed by bending in one stroke using a bending machine, which can ensure the processing accuracy and thus ensure the accuracy of the trigger force of the touch panel 3. At the same time, the processing difficulty and processing cost are lower.
[0053] See Figure 4The pressure sensor 12 is also elongated and extends along the length of the substrate portion 111. Specifically, the pressure sensor 12 includes a body portion 121 and an elastic protrusion portion 122 disposed on the body portion 121. The elastic protrusion portion 122 is configured to trigger the pressure sensor 12 after being compressed and undergoing elastic deformation. The body portion 121 contains a first electrode, and the elastic protrusion portion 122 contains a second electrode. When the elastic protrusion portion 122 is compressed and undergoes elastic deformation until the first electrode contacts the second electrode, the pressure sensor 12 is triggered and outputs an electrical signal. Preferably, the first electrode is a copper plate, and the second electrode is a copper strip.
[0054] Furthermore, it also includes two pressure plates 13 arranged vertically at intervals. The two pressure plates 13 are also elongated and extend along the length of the base plate portion 111. The pressure plates 13 are fixedly mounted on the front end face of the base plate portion 111 by several screws. A slot is provided on the rear side of each pressure plate 13, and the pressure plate 13 abuts against the body portion 121 through the slot, causing the body portion 121 to be pressed and fixed to the front end face of the base plate portion 111, thereby fixing the pressure sensor 12. The elastic protrusion 122 of the pressure sensor 12 is located between the two pressure plates 13 and protrudes forward from the pressure plates 13.
[0055] Therefore, by providing a pressure plate 13 on the substrate portion 111, the pressure sensor 12 can be pressed and fixed on the substrate portion 111 to prevent it from shifting, thereby ensuring the reliability of triggering.
[0056] See Figure 4-5 It also includes a transmission plate 14, which is also elongated and mounted on the front end face of the base plate 111. The transmission plate 14 is located at the front end of the pressure sensor 12 and can move back and forth relative to the mounting bracket. Preferably, both ends of the transmission plate 14 are limited to the base plate 111 by first limiting screws 16. The transmission plate 14 is configured to move backward and compress the elastic protrusion 122 when pushed by the touch panel 3.
[0057] Therefore, when the athlete presses or taps the touchpad 3, it can push the touchpad 3 to move backward. The touchpad 3 first abuts against the transmission plate 14 and drives it to continue moving backward. Then the touchpad 3 abuts against the elastic folded edge of the mounting bracket 11. The elastic folded edge is compressed and produces elastic deformation. The touchpad 3 continues to move backward and drives the transmission plate 14 to abut against the elastic protrusion 122 to trigger the pressure sensor 12.
[0058] Therefore, by setting the transmission plate 14, when the athlete presses or pats the touchpad 3, the touchpad 3 can transmit force to the transmission plate 14 and then to the pressure sensor 12, so that the elastic protrusion 122 on the pressure sensor 12 is subjected to force more evenly, thereby improving the stability and reliability of triggering.
[0059] In addition, when the touch panel 3 drives the transmission plate 14 to move backward and presses the elastic protrusion 122 until the transmission plate 14 abuts against the pressure plate 13, the touch panel 3 is limited at this time, thereby preventing the touch panel 3 from continuing to press the elastic fold and causing the elastic fold to undergo plastic deformation, thus ensuring the service life of the mounting bracket 11.
[0060] In addition, it also includes a limiting sleeve 15 made of plastic material, which has openings at both ends. The limiting sleeve 15 can be detachably fitted onto the outer periphery of the mounting bracket 11 through the openings at both ends and is used to limit the transmission plate 14 to the front end area of the elastic protrusion 122.
[0061] Since the transmission plate 14 is long and narrow, and its left and right ends are only limited and fixed by the first limiting screw 16, in order to prevent the middle area of the transmission plate 14 from sagging and detaching from the front end area of the elastic protrusion 122, this application uses a limiting sleeve 15 to limit the transmission plate 14, thereby ensuring the stability and reliability of the triggering.
[0062] In this embodiment, the limiting sleeve 15 is made of PE material.
[0063] Example 2
[0064] See Figure 6-9 This embodiment also provides a swimming timing trigger device, including the sensor module 1, frame body 2, and several touch panels 3 as described in Embodiment 1 above. The frame body 2 is a rectangular frame, installed on the pool wall and extending along the width of the pool channel. Several touch panels 3 are arranged side-by-side within the frame body 2 along the width of the pool channel. The upper end of each touch panel 3 is fixed within the frame body 2 by a second limiting screw 9, and the touch panel 3 can move relative to the frame body 2 in a front-back direction. Additionally, three sensor modules 1 are provided, spaced apart in the upper, middle, and lower parts of the frame body 2 and located behind the touch panels 3. Therefore, when a touch panel 3 is tapped or pressed, it moves backward relative to the frame body 2, triggering the sensor module 1.
[0065] Specifically, the top of the frame body 2 has a notch, through which the touch panel 3 can be inserted into the frame body 2 from top to bottom. The touch panel 3 can then be adjusted by moving it left and right along the width of the pool channel, so that all touch panels 3 can be installed into the frame body 2. In addition, a cover plate 5 is included. After all touch panels 3 are installed, the cover plate 5 can be placed on the notch to seal and limit the movement, while also making the overall structure neater and more aesthetically pleasing.
[0066] In addition, the top edges of the mounting bracket 11 at both ends of the sensor module 1 are bent to form a third folded edge 114 to form a slot. The left and right ends of the frame body 2 are provided with limiting blocks 21. The two ends of the mounting bracket 11 can be hooked onto the limiting blocks 21 through the slot to achieve detachable assembly and fixation.
[0067] Furthermore, it also includes a mounting plate 4, which has a first adjustment hole 41 extending along the width of the pool channel and a second adjustment hole 42 extending along the length of the pool channel. The first adjustment hole 41 is connected to the frame body 2, and the second adjustment hole 42 is connected to the pool.
[0068] Therefore, the frame body 2 is installed on the pool via the mounting plate 4. The mounting plate 4 can be moved and adjusted along the length and width of the pool channel, thereby effectively absorbing the error of the swimming pool mounting hole position. This allows the frame body 2 to fit better against the pool wall after installation, thus avoiding the problem of increased triggering force due to suspension, and also avoiding the problem of reduced triggering force due to pressure from the pool wall.
[0069] Of course, it should be noted that the second adjustment hole 42 can also be connected to the frame body 2, and the first adjustment hole 41 can be connected to the swimming pool, which can also achieve the same technical effect. There are no restrictions here.
[0070] Furthermore, due to certain processing errors in the frame body 2 and the pool wall, the rear side of the frame body 2 cannot fit snugly against the pool wall after installation, resulting in a suspended state and trigger failure. To address this, this application also provides several adjustment components on the frame body 2. These components include threaded holes on the rear end face of the frame body 2 and adjusting screws 7 screwed into the threaded holes. The axis of the threaded holes is set along the front-back direction. When the adjusting screws 7 are turned, they move along the front-back direction until the rear end of the adjusting screws 7 fits against the pool wall, thus eliminating the suspended state and ensuring the accuracy of the trigger force.
[0071] Preferably, several adjustment components are evenly arranged at various positions of the frame body 2, thereby ensuring that all positions of the frame body 2 can fit against the pool wall and avoid the phenomenon of being suspended.
[0072] In addition, to ensure that the adjusting screw 7 will not come loose, this application also screws a locking nut 8 onto the adjusting screw 7. With the locking nut 8 and the double nut locking the threaded hole, it can be ensured that the adjusting screw 7 will not come loose, thereby improving the stability and reliability of the product.
[0073] Additionally, a reinforcing rib plate 6 is provided on the frame body 2. This reinforcing rib plate 6 abuts against the rear side of the sensor module 1 to limit and fix the sensor module 1, preventing the sensor module 1 from shifting when squeezed by the touch panel 3. Preferably, the reinforcing rib plate 6 is arranged vertically in the up-down direction.
[0074] In this embodiment, the reinforcing rib 6 is provided with two ribs arranged at intervals on the left and right.
[0075] In summary, this utility model has the following technical effects:
[0076] (a) The swimming timing sensor module 1 of this utility model forms a first folded edge 112 by bending the substrate 111, and a second folded edge 113 by bending the first folded edge 112. The bending angle a of the substrate 111 and the bending angle b of the first folded edge 112 are both less than or equal to 90 degrees. Therefore, the first folded edge 112 formed by bending the substrate 111 and the second folded edge 113 formed by bending the first folded edge 112 can be formed by bending in one stroke with a bending machine. The processing accuracy can be guaranteed, thereby ensuring the accuracy of the trigger force of the touch panel 3. At the same time, the processing difficulty and processing cost are lower.
[0077] (ii) The swimming timing sensor module 1 of this utility model has a pressure plate 13 on the base plate 111. The pressure plate 13 can not only press and fix the pressure sensor 12 on the base plate 111, but also limit the touch plate 3 when the touch plate 3 drives the transmission plate 14 to move backward and squeeze the elastic protrusion 122 until the transmission plate 14 abuts against the pressure plate 13. This prevents the touch plate 3 from continuing to squeeze the elastic fold and causing the elastic fold to undergo plastic deformation, thereby ensuring the service life of the mounting bracket 11.
[0078] (III) The swimming timing sensor module 1 of this utility model, by setting a transmission plate 14, when the athlete presses or pats the touch plate 3, the touch plate 3 can transmit the force to the transmission plate 14 and then to the pressure sensor 12 through the transmission plate 14, so that the elastic protrusion 122 on the pressure sensor 12 is subjected to more uniform force, thereby improving the stability and reliability of triggering.
[0079] (iv) The swimming timing sensor module 1 of this utility model has an installation plate 4. The installation plate 4 can be moved and adjusted along the length direction of the pool channel and along the width direction of the pool channel, thereby effectively absorbing the error of the swimming pool installation hole. This allows the swimming timing trigger device to fit better against the pool wall after installation, thus avoiding the problem of increased triggering force due to suspension, and also avoiding the problem of reduced triggering force due to pressure from the pool wall.
[0080] (v) The swimming timing sensor module 1 of this utility model has several adjustment components on the frame body 2. When the frame body 2 is installed on the pool wall, the adjustment screw 7 in the adjustment component can be turned to make its rear end fit against the pool wall, thereby avoiding the gap between the rear side of the frame body 2 and the pool wall, and thus ensuring the accuracy of the triggering force.
[0081] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
