[0002] As an essential key component of a vehicle, the structure, material, performance, and quality of a tire directly affect multiple aspects such as the driving safety, comfort, and energy efficiency of the vehicle. During the driving process of an electric bicycle, the tire plays a role in shock absorption and noise reduction; An electric bicycle tire puncture strength detection device is a device used to test the ability of a bicycle tire to resist puncture by sharp objects, mainly composed of a puncture mechanism, a pressure detection mechanism, a fixing mechanism, etc.; First, fix the electric bicycle tire to the fixing mechanism, then start the pressure detection mechanism, the puncture mechanism moves towards the electric bicycle tire and pierces it. The pressure detection mechanism detects and collects pressure data in real time until the electric bicycle tire is completely pierced. After the detection is completed, the collected data is analyzed; During the driving process of an electric bicycle, the tire bears the weight and rotates continuously. However, in the prior art, when the puncture strength detection device for an electric bicycle tire detects the puncture strength, it cannot simulate the puncture strength under the condition of the electric bicycle being loaded, resulting in limitations; Therefore, we propose a puncture strength detection device for electric bicycle tires. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a puncture strength detection device for electric bicycle tires, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0005] Preferably, a puncturing block is installed on the detection ring; an installation hole is provided on the puncturing block, and a detection rod is slidably connected to the puncturing block; the puncturing needle is installed in the installation hole; a second pressure sensor is fixedly connected inside the puncturing block; a detection spring is fixedly connected between the second pressure sensor and the detection rod.

[0008] By driving the adjusting rod through the adjusting ring, the adjusting rod pulls the connecting rod, so that the connecting rod fixes the hub and the tire inside the electric bicycle tire. When electric bicycle tires of different specifications are fixed on the installation ring, the connecting rod moves different distances, so as to fix electric bicycle tires of different specifications. At the same time, the first pressure sensor of the present invention detects the pressure between the electric bicycle tire and the detection ring, and 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 under load, so that the puncture strength detection of the electric bicycle tire is more realistic. At the same time, the pressure transmitted to the second pressure sensor through the detection rod is used to detect the depth of the puncturing needle piercing into the electric bicycle tire.

[0009] Preferably, a detection groove is provided on the detection ring; a lifting block is slidably connected in the detection groove; the puncturing block is rotatably connected to the lifting block; a deflecting electric push rod is hinged between the lifting block and the puncturing block.

[0012] Preferably, an electromagnet block is fixedly connected inside the puncturing block.

[0013] After the puncturing needle pierces into the electric bicycle tire, the sealing plate seals the detection groove, so as to prevent the position where the electric bicycle tire is punctured from overlapping with the detection groove during the rotation process, so that the position where the electric bicycle tire is punctured cannot achieve the effect of repeated rolling during actual use, and further makes the detection of the present invention more in line with the actual use situation.

[0014] Advantages of the present invention: 1.

The first 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 is traveling under load, so that the puncture strength detection of the electric bicycle tire is more realistic. At the same time, the pressure transmitted to the second pressure sensor through the detection rod is used to detect the depth of the puncture needle penetrating into the electric bicycle tire.

[0015] 3. After the puncture needle penetrates into the electric bicycle tire in the present invention, the blocking plate blocks the detection groove, thereby preventing the situation where the position where the electric bicycle tire is punctured overlaps with the detection groove during the rotation process, so that the position where the electric bicycle tire is punctured cannot reach the effect of repeated rolling during actual use, and further making the detection of the present invention more in line with the actual use situation.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Refer to the attached drawings of the specification Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , an electric bicycle tire puncture strength detection device, comprising: Base 1, support frame 11, installation ring 12, installation block 13, detection ring 14 and detection mechanism 15; the installation block 13 is installed on the support frame 11; a lifting electric push rod 16 is fixedly connected to the support frame 11; the output end of the lifting electric push rod 16 is fixedly connected to an adjusting block 17; a first pressure sensor 18 is fixedly connected to the adjusting block 17, and a connecting frame 19 is slidably connected to the lifting block 31; the detection ring 14 is rotatably connected to the connecting frame 19; The installation ring 12 is rotatably connected to the support frame 11; a rotating motor 2 is fixedly connected inside the installation block 13; the rotating motor 2 drives the detection ring 14 to rotate; a piercing needle 21 is installed on the detection ring 14.

[0020] In the present invention, a piercing block 22 is installed on the detection ring 14; an installation hole 23 is provided on the piercing block 22, and a detection rod 24 is slidably connected to the piercing block 22; the piercing needle 21 is installed in the installation hole 23; a second pressure sensor 25 is fixedly connected inside the piercing block 22; a detection spring 26 is fixedly connected between the second pressure sensor 25 and the detection rod 24.

[0021] In the present invention, a connecting shaft 37 is fixedly connected to the installation ring 12, and a connecting rod 38 is slidably connected to the detection ring 14; the connecting rods 38 are radially distributed.

[0022] In the present invention, an adjusting ring 39 is rotatably connected to the mounting ring 12; adjusting rods 4 are evenly and rotatably connected to the adjusting ring 39 in the circumferential direction; the adjusting rods 4 are hinged to the connecting rods 38; the adjusting ring 39 is fixed to the mounting ring 12 by bolts.

[0023] In the present invention, an electric bicycle tire is mounted on a wheel hub, and then the wheel hub is passed through the connecting shaft 37. Subsequently, the adjusting ring 39 is rotated, so that the adjusting ring 39 drives the adjusting rods 4, and thus the adjusting rods 4 pull the connecting rods 38, causing the connecting rods 38 to move in a direction away from the connecting shaft 37, so that the connecting rods 38 clamp the wheel hub inside the wheel hub. Subsequently, the detection mechanism 15 is communicated with the valve core of the electric bicycle tire through a connecting interface, and then the electric bicycle tire is mounted on the present invention; 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, causing the detection ring 14 to move upward and contact 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 into the electric bicycle tire. The detection mechanism 15 is communicated with the electric bicycle tire, and the air pressure of the electric bicycle tire is detected in real time, and the first pressure sensor 18 detects the pressure between the detection ring 14 and the electric bicycle tire; In the present invention, the top end of the detection rod 24 is flush with the top end of the puncture needle 21. Therefore, when the puncture needle 21 pierces into the electric bicycle tire, the electric bicycle tire pushes the detection rod 24 downward, so that the detection rod 24 transmits the force to the second pressure sensor 25 through the detection spring 26, and thus the depth at which the puncture needle 21 pierces into the electric bicycle tire is detected according to the magnitude of the pressure received by the second pressure sensor 25. In the present invention, the adjusting ring 39 drives the adjusting rods 4, so that the adjusting rods 4 pull the connecting rods 38, and thus the connecting rods 38 fix the wheel hub and the tire inside the electric bicycle tire. When electric bicycle tires of different specifications are fixed on the mounting ring 12, the connecting rods 38 move different distances, so as to fix electric bicycle tires of different specifications. At the same time, the first pressure sensor 18 of the present invention detects the pressure between the electric bicycle tire and the detection ring 14, and the detection ring 14 can be used to squeeze the electric bicycle tire to simulate the situation when the electric bicycle tire is mounted on an electric bicycle and is carrying a load and driving, so that the puncture strength test of the electric bicycle tire is more realistic. At the same time, the pressure transmitted to the second pressure sensor 25 through the detection rod 24 is used to detect the depth at which the puncture needle 21 pierces into the electric bicycle tire.

[0024] Embodiment 2: On the basis of Embodiment 1, refer to the attached drawings of the specification Figure 1 、 Figure 2 、 Figure 3 、Figure 4 , Figure 5 , Figure 6 and Figure 7 , in the present invention, a detection groove 3 is formed in the detection ring 14; a lifting block 31 is slidably connected in the detection groove 3; a puncturing block 22 is rotatably connected to the lifting block 31; a biasing electric push rod 32 is hinged between the lifting block 31 and the puncturing block 22.

[0025] , 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.

[0026] , in the present invention, a sealing plate 34 is rotatably connected to the detection ring 14; the sealing plate 34 is located at the notch of the detection groove 3, and a sealing electric push rod 35 is hinged between the sealing plate 34 and the detection ring 14.

[0027] , in the present invention, an electromagnet block 36 is fixedly connected to the puncturing block 22.

[0028] The biasing electric push rod 32 drives the puncturing block 22 to rotate, so that the puncturing needle 21 rotates to an inclined state. Thus, when the puncturing needle 21 contacts the electric bicycle tire, the puncturing needle 21 pierces into the electric bicycle tire in an inclined state, so as to detect the puncturing strength of the electric bicycle tire when it is pierced into the electric bicycle tire at different angles; , in the present invention, the electromagnet block 36 on the puncturing block 22 generates a magnetic force to attract the puncturing needle 21 made of metal, thereby preventing the puncturing needle 21 from falling off; , in the present invention, the detection electric push rod 33 pushes the puncturing block 22 out of the detection groove 3, so that the puncturing needle 21 pierces into the electric bicycle tire. Subsequently, the detection electric push rod 33 pulls the puncturing block 22 downward, so that the puncturing needle 21 is separated from the puncturing block 22, and the puncturing block 22 is retracted into the detection groove 3. Subsequently, the sealing electric push rod 35 pushes the sealing plate 34, so that the sealing plate 34 seals 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 puncturing needle 21 pierces into the tire contacts the sealing plate 34, thereby preventing the situation that during the rotation of the electric bicycle tire, the position where the puncturing needle 21 pierces into the tire overlaps with the notch of the detection groove 3, and there is no support at the position where the electric bicycle tire is pierced, and the effect of repeatedly rolling over the punctured position when the electric bicycle tire is actually punctured cannot be achieved; , in the present invention, after the puncturing needle 21 pierces into the electric bicycle tire, the sealing plate 34 seals the detection groove 3, thereby preventing the situation that during the rotation process, the position where the electric bicycle tire is pierced overlaps with the detection groove 3, so that the position where the electric bicycle tire is pierced cannot reach the effect of repeated rolling during actual use, and further making the detection of the present invention more in line with the actual use situation.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present invention.
