Description

Technical Field

[0001] The present invention relates to the technical field of tire detection devices, and in particular to a puncture strength detection device for electric bicycle tires. Background Art

[0002] Tires are an indispensable and key component of vehicles. Their structure, materials, performance and quality directly affect the vehicle's driving safety, comfort and energy efficiency. During the driving of electric bicycles, tires play a role in cushioning and reducing noise.

[0003] The electric bicycle tire puncture strength test device is used to test the ability of bicycle tires to resist puncture by sharp objects. It mainly consists of a puncture mechanism, a pressure detection mechanism, and a fixing mechanism. First, the electric bicycle tire is fixed to the fixing mechanism. Then the pressure detection mechanism is activated. The puncture mechanism moves toward the electric bicycle tire and punctures the electric bicycle tire. The pressure detection mechanism detects and collects pressure data in real time until the electric bicycle tire is completely punctured. After the test is completed, the collected data is analyzed.

[0004] When an electric bicycle is in motion, its tires bear weight and rotate continuously. However, conventional tire puncture strength testing devices cannot simulate the puncture strength of electric bicycle tires under load conditions, resulting in limitations.

[0005] To this end, we propose an electric bicycle tire puncture strength detection device. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an electric bicycle tire puncture strength detection device, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for detecting the puncture strength of an electric bicycle tire, comprising:

[0008] A base, a support frame, a mounting ring, a mounting block, a detection ring, and a detection mechanism; the mounting block is mounted on the support frame; a lifting electric push rod is fixedly connected to the support frame; an adjustment block is fixedly connected to the output end of the lifting electric push rod; a No. 1 pressure sensor is fixedly connected to the adjustment block, and a connecting frame is slidably connected to the lifting block; the detection ring is rotatably connected to the connecting frame;

[0009] The mounting ring is rotatably connected to the support frame; a rotating motor is fixedly connected to the mounting block; the rotating motor drives the detection ring to rotate; and a puncture needle is installed on the detection ring.

[0010] Preferably, a puncture block is installed on the detection ring; a mounting hole is provided on the puncture block, and a detection rod is slidably connected to the puncture block; the puncture needle is installed in the mounting hole; a No. 2 pressure sensor is fixedly connected in the puncture block; a detection spring is fixedly connected between the No. 2 pressure sensor and the detection rod.

[0011] Preferably, a connecting shaft is fixedly connected to the mounting ring, and a connecting rod is slidably connected to the mounting ring; and the connecting rods are radially distributed.

[0012] Preferably, the mounting ring is rotatably connected to an adjusting ring; the adjusting ring is rotatably connected to an adjusting rod evenly in the circumferential direction; the adjusting rod is hinged to the connecting rod; and the adjusting ring is fixed to the mounting ring by bolts.

[0013] The adjusting ring drives the adjusting rod, so that the adjusting rod pulls the connecting rod, thereby fixing the wheel hub and tire on the inner side of the electric bicycle tire. When electric bicycle tires of different specifications are fixed on the mounting ring, the connecting rod moves different distances, thereby fixing electric bicycle tires of different specifications. At the same time, the No. 1 pressure sensor of the present invention detects the pressure between the electric bicycle tire and the detection ring. The electric bicycle tire can be squeezed by the detection ring to simulate the situation when the electric bicycle tire is installed on the electric bicycle and travels with a load, thereby making the puncture strength detection of the electric bicycle tire more realistic. At the same time, the pressure transmitted to the No. 2 pressure sensor through the detection rod is used to detect the depth of the puncture needle penetrating into the electric bicycle tire.

[0014] Preferably, a detection groove is provided on the detection ring; a lifting block is slidably connected in the detection groove; the puncture block is rotatably connected to the lifting block; and a biased electric push rod is hinged between the lifting block and the puncture block.

[0015] Preferably, a detection electric push rod is fixedly connected to the detection ring; and an output end of the detection electric push rod is fixedly connected to the lifting block.

[0016] Preferably, a blocking plate is rotatably connected to the detection ring; the blocking plate is located at the notch of the detection slot, and a blocking electric push rod is hinged between the blocking plate and the detection ring.

[0017] Preferably, an electromagnet block is fixedly connected to the puncture block.

[0018] After the puncture needle is inserted into the electric bicycle tire, the sealing plate blocks the detection groove, thereby preventing the punctured position of the electric bicycle tire from overlapping with the detection groove during rotation, so that the punctured position of the electric bicycle tire cannot achieve the effect of repeated rolling during actual use, thereby making the detection of the present invention more in line with actual use conditions.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention drives the adjusting rod through the adjusting ring, so that the adjusting rod pulls the connecting rod, thereby fixing the wheel hub and tire inside the electric bicycle tire. When electric bicycle tires of different specifications are fixed on the mounting ring, the connecting rod moves different distances, thereby fixing electric bicycle tires of different specifications.

[0021] 2. The No. 1 pressure sensor of the present invention detects the pressure between the electric bicycle tire and the detection ring. The detection ring can squeeze the electric bicycle tire to simulate the situation when the electric bicycle tire is installed on the electric bicycle and traveling with a load, thereby making the puncture strength detection of the electric bicycle tire more realistic. At the same time, the pressure transmitted to the No. 2 pressure sensor through the detection rod is used to detect the depth of the puncture needle penetrating into the electric bicycle tire.

[0022] 3. The present invention blocks the detection groove with a sealing plate after the puncture needle is inserted into the electric bicycle tire, thereby preventing the punctured position of the electric bicycle tire from overlapping with the detection groove during rotation. As a result, the punctured position of the electric bicycle tire cannot achieve the effect of repeated rolling during actual use, thereby making the detection of the present invention more in line with actual use conditions.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Refer to the attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , an electric bicycle tire puncture strength detection device, comprising:

[0033] Base 1, support frame 11, mounting ring 12, mounting block 13, detection ring 14 and detection mechanism 15; mounting block 13 is mounted on support frame 11; a lifting electric push rod 16 is fixedly connected to the support frame 11; an adjustment block 17 is fixedly connected to the output end of the lifting electric push rod 16; a No. 1 pressure sensor 18 is fixedly connected to the adjustment block 17; a connecting frame 19 is slidably connected to the lifting block 31; the detection ring 14 is rotatably connected to the connecting frame 19;

[0034] The mounting ring 12 is rotatably connected to the support frame 11 ; a rotating motor 2 is fixedly connected to the mounting block 13 ; the rotating motor 2 drives the detection ring 14 to rotate; a puncture needle 21 is installed on the detection ring 14 .

[0035] In the present invention, a puncture block 22 is installed on the detection ring 14; a mounting hole 23 is opened on the puncture block 22, and a detection rod 24 is slidably connected to the puncture block 22; the puncture needle 21 is installed in the mounting hole 23; a No. 2 pressure sensor 25 is fixedly connected in the puncture block 22; a detection spring 26 is fixedly connected between the No. 2 pressure sensor 25 and the detection rod 24.

[0036] In the present invention, a connecting shaft 37 is fixedly connected to the mounting ring 12 , and a connecting rod 38 is slidably connected to the mounting ring 12 ; the connecting rods 38 are radially distributed.

[0037] In the present invention, the mounting ring 12 is rotatably connected to the adjusting ring 39; the adjusting ring 39 is rotatably connected to the adjusting rod 4 evenly in the circumferential direction; the adjusting rod 4 and the connecting rod 38 are hinged; the adjusting ring 39 and the mounting ring 12 are fixed by bolts.

[0038] In the present invention, the electric bicycle tire is mounted on the wheel hub, and then the wheel hub is passed through the connecting shaft 37, and then the adjusting ring 39 is rotated so that the adjusting ring 39 drives the adjusting rod 4, and the adjusting rod 4 pulls the connecting rod 38, so that the connecting rod 38 moves in a direction away from the connecting shaft 37, so that the connecting rod 38 clamps the wheel hub on the inner side of the wheel hub, and then the detection mechanism 15 is connected to the valve core of the electric bicycle tire through the connecting interface, and then the electric bicycle tire is mounted on the present invention;

[0039] When performing a puncture strength test on an electric bicycle, the rotating motor 2 drives the detection ring 14 to rotate, and at the same time, the lifting electric push rod 16 pushes the mounting block 13 upward, so that the detection ring 14 moves upward and contacts the electric bicycle tire. The detection ring 14 drives the electric bicycle tire to rotate. When it rotates to the position of the puncture needle 21, the puncture needle 21 pierces the electric bicycle tire. The detection mechanism 15 is connected to the electric bicycle tire to detect the air pressure of the electric bicycle tire in real time, and the No. 1 pressure sensor 18 detects the pressure between the detection ring 14 and the electric bicycle tire.

[0040] In the present invention, the top of the detection rod 24 is flush with the top of the puncture needle 21. Therefore, when the puncture needle 21 is inserted into the tire of the electric bicycle, the tire of the electric bicycle pushes the detection rod 24 downward, so that the detection rod 24 transmits force to the second pressure sensor 25 through the detection spring 26. The depth of the puncture needle 21 inserted into the tire of the electric bicycle is detected according to the pressure applied to the second pressure sensor 25.

[0041] The present invention drives the adjusting rod 4 through the adjusting ring 39, so that the adjusting rod 4 pulls the connecting rod 38, so that the connecting rod 38 fixes the wheel hub and tire on the inner side of the electric bicycle tire. When electric bicycle tires of different specifications are fixed on the mounting ring 12, the connecting rod 38 moves different distances, thereby fixing electric bicycle tires of different specifications. At the same time, the No. 1 pressure sensor 18 of the present invention detects the pressure between the electric bicycle tire and the detection ring 14, and can squeeze the electric bicycle tire through the detection ring 14 to simulate the situation when the electric bicycle tire is installed on the electric bicycle and traveling with a load, thereby making the puncture strength detection of the electric bicycle tire more realistic. At the same time, the pressure transmitted to the No. 2 pressure sensor 25 through the detection rod 24 is used to detect the depth of the puncture needle 21 penetrating into the electric bicycle tire.

[0042] Example 2: Based on Example 1, refer to the attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In the present invention, a detection groove 3 is opened on the detection ring 14; a lifting block 31 is slidably connected in the detection groove 3; the puncture block 22 is rotatably connected to the lifting block 31; a biased electric push rod 32 is hinged between the lifting block 31 and the puncture block 22.

[0043] In the present invention, a detection electric push rod 33 is fixedly connected to the detection ring 14 ; the output end of the detection electric push rod 33 is fixedly connected to the lifting block 31 .

[0044] In the present invention, a blocking plate 34 is rotatably connected to the detection ring 14 ; the blocking plate 34 is located at the notch of the detection slot 3 , and a blocking electric push rod 35 is hinged between the blocking plate 34 and the detection ring 14 .

[0045] In the present invention, an electromagnet block 36 is fixedly connected to the puncture block 22 .

[0046] The deflected electric push rod 32 drives the puncture block 22 to rotate, causing the puncture needle 21 to rotate to an inclined state. When the puncture needle 21 contacts the tire of the electric bicycle, the puncture needle 21 penetrates into the tire of the electric bicycle in an inclined state, thereby testing the puncture strength of the electric bicycle tire when the needle is penetrated into the tire at different angles.

[0047] In the present invention, the electromagnet block 36 on the puncture block 22 generates a magnetic force to attract the metal puncture needle 21, thereby preventing the puncture needle 21 from falling;

[0048] In the present invention, the detection electric push rod 33 pushes the puncture block 22 out of the detection groove 3, so that the puncture needle 21 pierces the tire of the electric bicycle. Then the detection electric push rod 33 pulls the puncture block 22 downward, so that the puncture needle 21 is separated from the puncture block 22, and the puncture block 22 is retracted into the detection groove 3. Then the blocking electric push rod 35 pushes the blocking plate 34, so that the blocking plate 34 blocks the notch of the detection groove 3. Therefore, when the diameter of the electric bicycle tire is the same as that of the detection ring 14, the position where the puncture needle 21 pierces the tire contacts the blocking plate 34, thereby preventing the position where the puncture needle 21 pierces the tire from overlapping with the notch of the detection groove 3 during the rotation of the electric bicycle tire. The position where the electric bicycle tire is pierced has no support, and the effect of repeatedly rolling the puncture position when the electric bicycle tire is actually punctured cannot be achieved.

[0049] The present invention blocks the detection groove 3 with the sealing plate 34 after the puncture needle 21 is inserted into the electric bicycle tire, thereby preventing the punctured position of the electric bicycle tire from overlapping with the detection groove 3 during rotation. The punctured position of the electric bicycle tire cannot achieve the effect of repeated rolling during actual use, thereby making the detection of the present invention more in line with actual use conditions.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
