Description

Technical Field

[0002] The automobile cable is an important accessory on the car. It can control the actuator of the car remotely. The automobile cables include shift cables, clutch cables, throttle cables, door cables, brake cables, etc. The cables are used to control the tension, friction, load efficiency and other technologies of the automobile cables. Usually the cable is composed of a flexible shaft and a hose. The hose is used to seal and protect the flexible shaft to prevent dust or rainwater from entering the hose and corroding the flexible shaft, affecting the service life of the flexible shaft. On the other hand, the fatigue performance of the flexible shaft itself is also one of the factors affecting the service life of the flexible shaft. Therefore, in the production of the cable, the sealing and fatigue properties of the cable will be tested.

[0003] However, in the existing cable testing process, the cable is tested through a sealing test process and a fatigue test process. This testing method makes the testing efficiency low. In addition, since the sealing and fatigue tests are conducted separately, the testing device cannot simulate the sealing test of the cable in a working state, and can only test the sealing of the cable when it is not working, resulting in inaccurate test results and large errors, which greatly affects the effect.

[0044] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings.

[0045] The embodiment of the present application provides a multifunctional detection device for simultaneously detecting the fatigue and sealing of a cable 20, wherein the cable 20 includes a flexible shaft 21 and a hose 22, wherein the hose 22 is sleeved on the flexible shaft 21, and the multifunctional detection device includes a bearing assembly 11, a first detection assembly 12, and a second detection assembly 13. By way of example, the cable 20 in the present embodiment may be a shift cable 20, a clutch cable 20, a throttle cable 20, a door cable 20, or a brake cable 20, etc. Furthermore, the present application takes a shift cable as an example for explanation, and the shift cable is also called a gearbox cable, wherein the first end of the cable 20 is used to connect to the gearbox end, and the second end of the cable 20 is used to connect to the gear lever in the cockpit.

[0046] It can be understood that the main function of the shift cable 20 is to transmit torque. The first end of the cable 20 is connected to the gearbox, and the second end of the cable 20 is connected to the gear lever in the cockpit. The driver pulls the cable 20 by operating the gear lever to adjust the gear position of the gearbox, thereby realizing the gear shifting operation and changing the vehicle's running speed.

[0047] Please refer to Figure 1 Specifically, the cable 20 includes a soft shaft 21 and a hose 22, the hose 22 is sleeved on the soft shaft 21, the hose 22 includes a hose body 221 and a telescopic sheath 222, the telescopic sheath 222 is sleeved on the hose 22 located at the first end of the cable 20, and one end of the telescopic sheath 222 is connected to the hose body 221, and the other end of the telescopic sheath 222 is connected to the soft shaft 21.

[0048] Please also read Figure 1 and Figure 2The embodiment of the present application provides a multifunctional detection device for simultaneously detecting the fatigue and sealing of the cable 20. The multifunctional detection device includes a load-bearing component 11, a first detection component 12 and a second detection component 13. The load-bearing component 11 is used to fix the first end of the cable 20. The first detection component 12 is connected to the load-bearing component 11 and is detachably connected to the flexible shaft 21 located at the first end of the cable 20. The first detection component 12 is used to drive the flexible shaft 21 to reciprocate to detect the fatigue of the cable 20. The second detection component 13 is connected to the load-bearing component 11 and is used to spray a liquid medium to the first end of the cable 20 to detect the sealing between the hose 22 and the flexible shaft 21.

[0049] In the above-mentioned multifunctional detection device, the first end of the cable 20 is first fixed to the bearing component 11, and then the first detection component 12 is connected to the flexible shaft 21 located at the first end of the cable 20. Then, the first detection component 12 drives the flexible shaft 21 to reciprocate so as to simulate the cable 20 in a working state and realize fatigue detection of the cable 20. Next, the liquid medium is sprayed to the first end of the cable 20 through the second detection component 13 so as to simulate the sealing detection of the cable 20 in a working state. In this way, the fatigue and sealing of the cable 20 are detected at the same time by the multifunctional detection device, which improves the detection efficiency of the cable 20. At the same time, the sealing of the cable 20 in the simulated working state is detected by the second detection component 13, which improves the detection effect, thereby achieving the improvement of the detection effect on the basis of improving the detection efficiency of the cable 20.

[0050] In this embodiment, the liquid medium is not limited. For example, the liquid medium can be clean water or clean water with color. Clean water with color makes it easier to observe whether there is leakage. It can also be kerosene with stronger penetration.

By arranging the telescopic sheath 222 at the first end of the cable 20, the telescopic sheath 222 can be telescoped during the telescopic process of the flexible shaft 21, thereby providing a better sealing performance, thereby achieving better dustproof and waterproof effects. When the first end of the cable 20 pulls the first detection component 12 to drive the flexible shaft 21 to reciprocate, the flexible shaft 21 also drives the telescopic sheath 222 to perform telescopic movement.

At the same time, the second detection component 13 performs sealing detection on the telescopic sheath 222 in a simulated working state, so as to improve the detection effect, thereby improving the detection effect of the telescopic sheath 222 on the basis of improving the detection efficiency of the telescopic sheath 222.

The storage box 113 is connected to a side of the supporting member 111 away from the first detection component 12. The water tank 131 is stored in the storage box 113 so that the water tank 131 can be stored and protected by the storage box 113.

[0058] The present application does not limit the specific structure of the fixing frame 112. Exemplarily, the fixing frame 112 includes an L-shaped vertical plate; a threaded hole is provided on the bottom bending portion of the L-shaped vertical plate to facilitate the L-shaped vertical plate to be fixed to the supporting member 111 by bolts, and a buckle compatible with the cable 20 is provided on the upper end of the L-shaped plate for clamping and fixing the first end of the cable 20; or, the fixing frame 112 includes a vertical plate, the bottom of the vertical plate is welded to the supporting member 111, and a buckle compatible with the cable 20 is provided on the upper end of the vertical plate for clamping and fixing the first end of the cable 20.

[0059] Furthermore, a load-bearing wheel 115 assembly is provided at the bottom of the storage box 113. The load-bearing wheel 115 assembly is composed of a plurality of running wheels.

[0061] In this way, when taking or placing the water tank 131, first open the door of the storage box 113, then push the water tank body 1311 completely into the storage box 113 or leave the storage box 113 along the notch 114, and finally close the door, thereby improving the convenience of taking or placing the water tank 131, and facilitating the storage and discharge of the liquid medium in the water tank 131.

[0062] In this embodiment, the size of the notch 114 is larger than the size of the water tank 131, so as to facilitate the water tank 131 to be completely pushed into the storage box 113 and prevent the water tank 131 from being not completely pushed into the storage box 113 and causing the box door to be unable to close.

[0063] Furthermore, the running wheel assembly 1312 is composed of a plurality of running wheels. The present application does not limit the number of running wheels. For example, the number of running wheels may be 4, 6, or 8, etc.

[0064] See also Figure 3 In some embodiments, the supporting component 11 also includes a water receiving pool 116, which is connected to the side of the supporting component 111 away from the storage box 113, and the fixing frame 112 is fixed to the bottom wall of the water receiving pool 116. The first end of the cable 20 is arranged inside the water receiving pool 116, and the first detection component 12 and the first end of the cable 20 can be movably passed through the side wall of the water receiving pool 116.

[0065] In this way, the liquid medium sprayed by the second detection component 13 is received by the water receiving pool 116 to prevent the liquid medium from splashing out. At the same time, when the water receiving pool 116 receives enough liquid medium, the liquid medium can be directly immersed in the liquid medium in the water receiving pool 116. At this time, there is no need to start the water pump, thereby reducing the energy consumption required for detection, which is conducive to reducing the detection cost.

[0066] Furthermore, a drain outlet is provided at the bottom of the water receiving pool 116, and the drain outlet is connected to the water tank 131 through a connecting pipe, so that the liquid medium can be recovered through the water tank 131, thereby realizing the recycling of the liquid medium, which is beneficial to saving raw materials and reducing detection costs.

[0067] See also Figure 2 In some embodiments, the carrier component 11 also includes a waterproof cover 117, which is connected to the side of the carrier 111 facing away from the storage box 113. The spray ports of the first detection component 12 and the second detection component 13 are both received in the waterproof cover 117 to prevent the liquid medium from splashing out and contaminating other components, thereby preventing the liquid medium from contaminating the environment.

[0068] Please also read Figure 1 and 5 In some embodiments, the cable 20 further includes a sealing bracket 23 and a sealing member 24, the sealing member 24 is embedded in the sealing bracket 23 and used to seal the sealing bracket 23, the bearing assembly 11 includes a detection bracket 118 adjacent to the water receiving pool 116, the detection bracket 118 is provided with a positioning hole 119 for positioning the sealing bracket 23, the sealing bracket 23 is detachably connected to the detection bracket 118, and the second detection assembly 13 is also used to spray a liquid medium toward one side of the sealing member 24 to detect the sealing between the sealing bracket 23 and the sealing member 24.

[0069] During detection, the seal 24 is sprayed upward at an elevation angle of 45° through the nozzle of the second detection component 13, and the spraying direction is that the seal 24 is sprayed toward the side of the first end of the cable 20, and then the side of the seal 24 toward the second end of the cable 20 is detected to seep out whether there is spray medium, and this detection can be carried out simultaneously with the detection of the first end of the cable 20. At this time, the water receiving pool 116 can prevent the liquid medium from splashing onto the sealing structure, that is, the position of the sealing bracket 23 and the seal 24, so as to avoid interfering with the detection of the seal 24.

[0070] In this way, the multifunctional detection device is also used to perform sealing detection on the sealing structure in the cable 20, making the detection of the cable 20 more comprehensive, thereby obtaining a more reliable sealing structure, and further improving the detection effect of the cable 20. At the same time, by combining the detection bracket 118 with the second detection component 13, the detection equipment is optimized and the production cost of the multifunctional detection device is reduced.

[0073] It can be understood that the sealing bracket 23 is welded and fixed to the mounting hole on the bulkhead of the cockpit, and the sealing bracket 23 is sealed by setting a seal 24, so that the sealing of the mounting hole on the cockpit is achieved by the sealing bracket 23 and the seal 24. The detection bracket 118 in the present application is used to simulate the bulkhead of the cockpit, and accordingly, the positioning hole 119 on the detection bracket 118 simulates the mounting hole on the bulkhead.

[0074] The working principle of the above multifunctional detection device is as follows:

[0075] First, the driving member 121 drives the connecting member 122 to drive the flexible shaft 21 and the telescopic sheath 222 of the cable 20 to make reciprocating motion, so as to perform fatigue testing on the flexible shaft 21 and the telescopic sheath 222; then, the water pump is started, and the water nozzle of the water pump sprays liquid medium toward the first end of the cable 20, so as to perform a sealing test while performing fatigue testing on the first end of the cable 20; finally, the liquid medium is sprayed toward the side of the sealing member 24 toward the first end of the cable 20 through the water nozzle at the other end of the water pump, and the sealing test of the sealing member 24 is achieved by detecting whether there is liquid medium leakage from the other end.
