Description

Technical Field

[0001] The invention relates to the field of counting mechanisms, in particular to a counter and a rope skipping counting detection device. Background Art

[0002] Counting mechanisms are structures used to count and record quantities and are largely described in IPC classification code G06M.

[0003] Accurate counting is necessary during the transportation of items. During the loading and unloading of items into vehicles, it is necessary to ensure that the number of items being loaded and unloaded is correct; however, this process currently usually relies on manual counting, where workers count while moving items, which can easily lead to counting errors. Despite this, the counting mechanism described by the applicant in IPC classification number G06M does not provide an effective solution to the above technical problems.

[0004] In addition, counting is equally important when doing rope skipping exercises. Currently, exercisers use a ropeless rope skipping electronic counter, which can be operated without actually skipping the rope; however, if the exerciser only shakes the counter without actually jumping, the counter will still record one jump, which is obviously inaccurate.

[0005] The present application aims to provide a counting mechanism. Summary of the invention

[0006] The invention provides a counting mechanism and application thereof, and a skipping rope counting detection device, so as to solve the above technical problems.

[0007] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0008] Counting mechanism,

[0009] A base, which is used to make contact with the ground;

[0010] A load-bearing platform, which is located directly above the base;

[0011] An elastic buffer structure, which is installed between the bearing platform and the base;

[0012] A contact sensor is used to detect whether there is any cargo placed on the load-bearing platform; the contact sensor is located between the base and the load-bearing platform, and the contact sensor is fixedly connected to the base;

[0013] Sound-generating element;

[0014] A single chip microcomputer, which is electrically connected to the sound generating element and the contact sensor respectively;

[0015] Among them, in the process of the carrying platform applying and removing gravity in sequence, the carrying platform and the contact sensor switch between disconnection and contact or between contact and disconnection; the microcontroller can receive the contact and disconnection switching actions of the contact sensor, and the microcontroller accumulates the counts, and the accumulated total number plays a specific digital sound through the sound-emitting element.

[0016] Furthermore, a triggering member is fixedly arranged on the lower side of the carrying platform; a supporting member is fixedly arranged on the upper side of the base; and the contact sensor is fixedly connected to the supporting member;

[0017] In the process of the load-bearing platform applying and canceling gravity in sequence, the load-bearing platform and the contact sensor switch between disconnection and contact or between contact and disconnection.

[0018] Further, the detection end of the contact sensor is upward, and the trigger member is located at the upper end of the detection end of the contact sensor;

[0019] When the load-bearing platform applies gravity, the trigger member moves downward to press the detection end of the contact sensor; the material of the trigger member is a flexible rubber material.

[0020] Further, the upper end of the support member is bent to form a bent portion, and the contact sensor is fixed to the bent portion of the support member;

[0021] The lower end of the trigger member is bent to form a trigger portion, and the trigger portion of the trigger member is located directly below the detection end of the contact sensor;

[0022] When the load-bearing platform applies gravity, the detection end of the contact sensor is out of contact with the trigger part of the trigger member; after the load-bearing platform removes gravity and the trigger member rises to the maximum height, the detection end of the contact sensor is in contact with the trigger part of the trigger member again.

[0023] Furthermore, two legs are provided, and the two legs are respectively distributed on the outer sides of the two adjacent sleeves of the counting mechanism; the legs are rotatably connected to the upper side of the base; a roller is installed at the first end of the legs; the other end of the legs is a clamping end and the clamping end is located between the base and the bearing platform;

[0024] The support is fixed to the lower side of the bearing platform; the support is provided with a slideway, and the clamping end can enter the slideway during the rotation of the support leg;

[0025] Among them, the clamping end has a downward pressing inclined surface, and the slide is provided with an entrance inclined surface below its entrance; when the clamping end has not entered the slide, the downward pressing inclined surface is opposite to the entrance inclined surface; when the clamping end enters the slide, the downward pressing inclined surface presses the entrance inclined surface downward, and the bearing platform moves with the trigger member away from the contact sensor detection end; at the same time, when the clamping end enters the slide to a preset position, the locking mechanism locks the support leg and the support together.

[0026] Furthermore, there are two limit springs; one end of the spring is fixedly connected to the base;

[0027] The other ends of the two springs are fixed to the legs respectively;

[0028] When the clamping end does not enter the slideway, the spring always pulls the leg to contact the sleeve.

[0029] Furthermore, the clamping ends are provided with sockets; the support is provided with an unlocking channel, and the unlocking channel is located directly above the slideway;

[0030] The locking mechanism includes a positioning member, a connecting beam, and a positioning spring; the connecting beam is located in the unlocking channel, the upper ends of the two positioning members are fixedly connected to the connecting beam, and the lower ends of the positioning members penetrate into the slideway; the positioning spring always pulls the lower ends of the positioning members into the slideway;

[0031] Among them, the clamping end is located on the upper side of the first extrusion surface and an upward inclined surface is provided; when the clamping end enters the slideway, the upward inclined surface overcomes the elastic force of the positioning spring and squeezes the positioning piece up first, and when the socket moves to just below the positioning piece, the elastic force of the positioning spring pulls the lower end of the positioning piece into the socket, thereby completing the positioning of the clamping end / leg.

[0032] Further, the unlocking structure includes a slide seat, a retaining spring, a sliding rod, and an unlocking member;

[0033] The sliding rod slides through the slide seat, and the slide seat is fixedly connected to the lower side of the carrying platform;

[0034] The unlocking piece is fixed to one end of the sliding rod, and an unlocking surface is provided on one side of the unlocking piece facing the connecting beam, and the unlocking surface can lift the connecting beam upward and pull the positioning piece out of the socket during the process of squeezing the lower side of the connecting beam;

[0035] The two ends of the maintaining spring are respectively fixed to the unlocking piece and the sliding rod; the maintaining spring can maintain the separation of the unlocking surface and the connecting beam.

[0036] The beneficial effects of the present invention are:

[0037] 1. In order to ensure the accuracy of rope skipping counting, the system is designed to count only after the jumper actually jumps into the air. In this way, the counter will increase once each time the jumper leaves the ground and lands again, thus ensuring the accuracy and reliability of the counting results. This design effectively avoids erroneous counting caused by misoperation or other non-jumping actions, allowing jumpers to focus more on their exercise without worrying about the accuracy of the count.

[0038] 2. Since the trigger member 11 is out of contact with the contact sensor 40 during the movement, the problem of vibration and frequent counting of the carrying platform 10 during the movement is prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0059] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0060] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0061] Considering the existing technology, the number of goods loaded and unloaded needs to be counted while being manually carried, which is prone to counting errors; in addition, at present, if the exerciser only shakes the electronic counter of the ropeless skipping rope and does not jump, the counter will still record one skipping, which is obviously inaccurate. Considering the above problems, the counting structure of the present application is in the shape of a platform, and the counting structure will count once only when the object / person presses down the platform for a certain distance; it is used to solve the above problems of the existing technology.

[0062] First, the scenario of loading and unloading goods is described: the vehicle stops at the designated area, and there are porters under and on the vehicle. The porters under the vehicle move the goods to the ground next to the vehicle's compartment, and then the porters under the vehicle lift or raise the goods to help the personnel on the vehicle place the goods in the compartment; at the same time, the personnel on the vehicle record or remember the goods on the vehicle.

[0063] Embodiment 1

[0064] See also Figure 1 , Figure 2 The counting mechanism includes a carrying platform 10, a base 20, an elastic buffer structure 30, a contact sensor 40, a single chip microcomputer 50, and a sound element 60.

[0065] The base 20 is used to contact the ground; that is, when the counting mechanism is in operation, the base 20 is placed on the ground.

[0066] The load-bearing platform 10 is located directly above the base 20; the load-bearing platform 10 is a supporting platform that can support rope skippers or goods; when the counting mechanism is used as a counting structure in the process of loading goods into a vehicle, the counting mechanism is placed on the ground next to the vehicle compartment, and the porters under the vehicle carry the goods to the load-bearing platform 10 of the counting mechanism, and then lift or raise the goods on the load-bearing platform 10 to a height where the people on the vehicle can receive the goods; at the same time, the counting mechanism can record the number of goods on the vehicle. In addition, the process of the porters under the vehicle lifting or raising the goods to a height where the people on the vehicle can receive the goods on the basis of the load-bearing platform 10 is more labor-saving.

[0067] The elastic buffer structure 30 is installed between the carrying platform 10 and the base 20 ; the elastic buffer structure 30 provides a certain descending stroke for the carrying platform 10 and provides a certain buffer.

[0068] The contact sensor 40 is used to detect whether there is any cargo placed on the carrying platform 10 ; the contact sensor 40 is located between the base 20 and the carrying platform 10 , and the contact sensor 40 is fixedly connected to the base 20 .

[0069] The single chip microcomputer 50 is electrically connected to the sound generating element 60 and the contact sensor 40 respectively.

[0070] In the process of the carrying platform 10 applying and removing gravity in sequence, the carrying platform 10 and the contact sensor 40 switch between disconnection and contact or between contact and disconnection; the microcontroller 50 can receive the switching action of contact and disconnection of the contact sensor 40, and the microcontroller 50 accumulates the count, and the accumulated total number plays a specific digital sound through the sound element 60.

[0071] To sum up, when the exerciser lands on the carrying platform 10 and jumps into the air, or when the goods are placed on the carrying platform 10 and transported onto the vehicle, it is the above-mentioned process of "applying and removing gravity in sequence on the carrying platform 10". During this process, the single-chip microcomputer 50 can receive the contact and disconnection switching actions of the contact sensor 40, and the single-chip microcomputer 50 accumulates the counts, and the accumulated total number plays a specific digital sound through the sound-emitting element 60; not only the counting of the goods on the vehicle is realized, but also the effect that the jumper must jump into the air before the counting is achieved.

[0072] Furthermore, a plurality of elastic buffer structures 30 are provided; wherein the elastic buffer structure 30 comprises a sleeve 31, a core shaft 32, and a buffer spring 33;

[0073] The lower end of the sleeve 31 is fixedly connected to the base 20 , and the core shaft 32 slides through the sleeve 31 ; the two ends of the buffer spring 33 are fixedly connected to the upper end of the sleeve 31 and the lower side of the bearing platform 10 , respectively.

[0074] When gravity is applied to the carrying platform 10 , the buffer spring 33 is further compressed, and the carrying platform 10 descends a certain distance; when gravity is removed from the carrying platform 10 , the buffer spring 33 restores the carrying platform 10 to its original height.

[0075] Furthermore, a trigger member 11 is fixedly disposed on the lower side of the carrying platform 10 ; a support member 21 is fixedly disposed on the upper side of the base 20 ; and the contact sensor 40 is fixedly connected to the support member 21 .

[0076] During the process of the carrying platform 10 applying and canceling gravity in sequence, the carrying platform 10 and the contact sensor 40 switch between disconnection and contact or between contact and disconnection.

[0077] Furthermore, there are two arrangement postures of the contact sensor 40, which are described in detail below.

[0078] Embodiment 2

[0079] The first arrangement posture of the contact sensor 40; the difference between the second embodiment and the first embodiment is as follows.

[0080] See also Figure 1 , the detection end of the contact sensor 40 is upward, and the trigger member 11 is located at the upper end of the detection end of the contact sensor 40;

[0081] When the load-bearing platform 10 applies gravity, the trigger member 11 moves downward to press the detection end of the contact sensor 40; the material of the trigger member 11 is a flexible rubber material. However, the arrangement posture of the first contact sensor 40 has the following characteristics: objects of different weights are placed on the load-bearing platform 10, and the trigger member 11 moves downward to different distances, and the force exerted by the trigger member 11 on the contact sensor 40 is different, which is not conducive to improving the service life of the contact sensor 40.

[0082] Embodiment 3

[0083] The second arrangement posture of the contact sensor 40; the difference between the second embodiment and the first embodiment is as follows.

[0084] participate Figure 2 The upper end of the support member 21 is bent to form a bent portion, and the contact sensor 40 is fixed to the bent portion of the support member 21 .

[0085] The lower end of the trigger member 11 is bent to form a trigger portion, and the trigger portion of the trigger member 11 is located directly below the detection end of the contact sensor 40 .

[0086] When the load-bearing platform 10 applies gravity, the detection end of the contact sensor 40 is out of contact with the trigger part of the trigger member 11. After the load-bearing platform 10 cancels gravity, when the trigger member 11 rises to the maximum height, the detection end of the contact sensor 40 just contacts the trigger part of the trigger member 11 again. The gravity application and cancellation process completes the accumulation of counts.

[0087] Compared with the first structure, the second structure has the following advantages: when the supporting platform 10 of the second structure is at the maximum height, the trigger member 11 just triggers the detection end of the contact sensor 40; no matter how the applied gravity is, the effect of just triggering the detection end of the contact sensor 40 can be achieved.

[0088] Furthermore, a piston block 321 is disposed at the lower end of the core shaft 32, and the piston block 321 is located inside the sleeve 31;

[0089] The piston block 321 is smaller than the diameter of the upper end of the sleeve 31 to prevent the piston block 321 from sliding out of the upper end of the sleeve 31 .

[0090] Embodiment 4

[0091] The differences between the fourth embodiment and the third embodiment are as follows.

[0092] See also Figure 5 , 6 There are two legs 70, which are respectively distributed on the outer sides of the two sleeves 31 adjacent to the counting mechanism; the legs 70 are rotatably connected to the upper side of the base 20; a roller 71 is installed at the first end of the legs 70, see Fig. 9 The two rollers are used for the equipment to roll on the ground; the other end of the leg 70 is a clamping end 72 and the clamping end 72 is located between the base 20 and the carrying platform 10;

[0093] The support 80 is fixed to the lower side of the carrying platform 10 ; the support 80 is provided with a slideway 81 , and the clamping end 72 can enter the slideway 81 during the rotation of the support leg 70 .

[0094] Among them, the clamping end 72 has a downward pressing inclined surface 721, and the slide 81 is provided with an entrance inclined surface 811 below its entrance; when the clamping end 72 has not entered the slide 81, the downward pressing inclined surface 721 is opposite to the entrance inclined surface 811; in the process of the clamping end 72 entering the slide 81, the downward pressing inclined surface 721 presses the entrance inclined surface 811 downward, and at the same time, the support 80 moves with the carrying platform 10 toward the base 20, and the carrying platform 10 moves with the trigger member 11 away from the detection end of the contact sensor 40; at the same time, when the clamping end 72 enters the slide 81 to the preset position, the locking mechanism 90 locks the support leg 70 and the support 80 together.

[0095] In summary, it not only fixes the positions of the two legs 70, but also makes the trigger 11 disengage from the contact sensor 40. Some carriages are more than ten meters long. At first, the position where the goods are loaded is the head of the carriage. During the loading process, the position where the goods are loaded gradually moves to the rear of the carriage, that is, the position where the goods are loaded gradually moves from the head of the carriage to the rear of the carriage. In the process of using the counting structure to assist in loading, the counting structure needs to move. After the clamping end 72 enters the slide 81, the leg 70 is locked and cannot rotate relative to the load-bearing platform 10 / base 20, and the counting structure can move by means of the roller 71. Since the trigger 11 is disengaged from the contact sensor 40 during the movement, the load-bearing platform 10 is prevented from vibrating and frequently counting during the movement.

[0096] Furthermore, there are two limit springs 100; one end of the spring 100 is fixedly connected to the base 20;

[0097] The other ends of the two springs 100 are respectively fixed to the legs 70;

[0098] When the clamping end 72 does not enter the slideway 81, the spring 100 always pulls the leg 70 to contact the sleeve 31. That is, when the clamping end 72 is not locked by the locking mechanism 90, the limit spring 100 maintains the position of the two legs 70 stable.

[0099] For further information, see Figure 6 The clamping end 72 is provided with a socket 723 , and the socket 723 is used for positioning by the locking mechanism 90 ; the support 80 is provided with an unlocking channel 82 , and the unlocking channel 82 is located directly above the slideway 81 .

[0100] See also Figure 7 The locking mechanism 90 includes a positioning member 91, a connecting beam 92, and a positioning spring 93; the connecting beam 92 is located in the unlocking channel 82, the positioning member 91 is used to insert into the socket 723 to position the clamping end 72 / leg 70, the upper ends of the two positioning members 91 are fixedly connected to the connecting beam 92, and the lower ends of the positioning members 91 pass through the slide 81; the positioning spring 93 always pulls the lower end of the positioning member 91 into the slide 81.

[0101] The clamping end 72 is located on the upper side of the first extrusion surface 721 and has an upward inclined surface 722; when the clamping end 72 enters the slideway 81 (see Figure 8 ), the upward inclined surface 722 overcomes the elastic force of the positioning spring 93, and pushes the positioning member 91 up first. When the socket 723 moves to just below the positioning member 91, the elastic force of the positioning spring 93 pulls the lower end of the positioning member 91 into the socket 723, thereby completing the positioning of the clamping end 72 / leg 70.

[0102] For further information, see Figure 7 When the leg 70 is unlocked from the locking mechanism 90, the user needs to insert the rod into the unlocking channel 82 and use the rod to lift the connecting beam 92 to pull the positioning member 91 out of the socket 723, and then the leg 70 returns to the initial position under the action of the limit spring 100. However, the rod is not attached to the counting structure, which makes unlocking inconvenient; therefore, a dedicated unlocking structure 110 is designed.

[0103] See also Figure 7 , the unlocking structure 110 includes a slide seat 111, a retaining spring 112, a sliding rod 113, and an unlocking member 114;

[0104] The sliding rod 113 slides through the slide seat 111, and the slide seat 111 is fixedly connected to the lower side of the carrying platform 10;

[0105] The unlocking member 114 is fixed to one end of the sliding rod 113, and an unlocking surface 1141 is provided on the side of the unlocking member 114 facing the connecting beam 92. The unlocking surface 1141 can lift the connecting beam 92 upward and pull the positioning member 91 out of the socket 723 during the process of squeezing the lower side of the connecting beam 92.

[0106] The two ends of the maintaining spring 112 are respectively fixed to the unlocking member 114 and the sliding rod 113 ; the maintaining spring 112 can maintain the unlocking surface 1141 and the connecting beam 92 from being separated.

[0107] Among them, during the unlocking process of the support leg 70 and the locking mechanism 90, the sliding rod 113 moves along the guide of the slide seat 111 to the unlocking channel 82, and the unlocking surface 1141 of the unlocking member 114 can lift the connecting beam 92 and pull the positioning member 91 out of the socket 723 during the process of squeezing the lower side of the connecting beam 92.

[0108] For further information, see Fig. 9 A handle 1131 is fixedly provided at the other end of the sliding rod 113 away from the unlocking channel 82 .

[0109] When the legs 70 are locked, the handle 1131 is grasped so that the device can be pulled forward.

[0110] In summary, the device is not only applicable to truck loading counting but also to rope skipping counting. When the device is used for rope skipping, a rubber layer is provided on the side of the load-bearing platform 10 and the base 20 that are away from each other, so that noise can be reduced when exercising in a space above the second floor; in order to ensure the accuracy of rope skipping counting, it is designed that the counting will only be performed after the rope jumper actually jumps into the air. In this way, the counter will only increase once each time the rope jumper leaves the ground and lands again, thereby ensuring the accuracy and reliability of the counting result. This design effectively avoids erroneous counting caused by misoperation or other non-jumping actions, so that rope jumpers can focus more on their exercise without having to worry about the accuracy of the counting.

[0111] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
