Description

Technical Field

[0001] This utility model relates to a product life testing device, and more specifically, to a durability testing device for rocker switches. Background Technology

[0002] A rocker switch, also known as a rocker switch, is a type of circuit switch hardware product. It features a rocker handle design and is widely used in products such as electric vehicles, motorcycles, and household appliances.

[0003] Motorcycle ignition switches often use rocker switches. Although most rocker switches that have passed safety certification have undergone lifespan testing, the durability of different batches of products can vary significantly. Therefore, it is essential to conduct durability testing on purchased motorcycle ignition switches. Previously, durability testing of motorcycle ignition switches was conducted manually by motorcycle manufacturers. The timing and frequency of these tests could not be guaranteed, making it difficult to accurately reflect the durability quality of the ignition switch. Furthermore, manual testing was costly and labor-intensive.

[0004] Existing rocker switch life testing devices are often quite complex in structure. During testing, the rocker switch is typically triggered by various mechanisms, including swing-triggered, lever-triggered, and roller-triggered structures. Swing-triggered structures, such as the "Rocker Switch Life Testing Device" disclosed in Chinese Patent Publication No. CN209400672U, utilize a motor to drive a contact rod to swing back and forth, thus switching the rocker switch. Lever-triggered structures, such as the "Rocker Switch Fixture for a Durability Testing Bench" disclosed in Chinese Patent Publication No. CN220710177U, have a rotatable lever mounted on the upper part of the rocker switch. A connecting rod drives the lever to rotate back and forth, thereby switching the rocker switch. Roller-triggered structures, such as the "Rocker Switch Life Testing Device" disclosed in Chinese Patent Publication No. CN220542411U, utilize a roller rolling back and forth on the rocker switch to switch it. These testing devices have a relatively complex structure and are not flexible and efficient enough for toggling rocker switches. Therefore, it is necessary to develop a durability testing device that is easy to manufacture and convenient to use to address the above problems and meet the durability testing needs of motorcycle manufacturers for ignition switch. Summary of the Invention

[0005] 1. Technical problem to be solved by the utility model

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology, such as complex structure, and to provide a durability testing device for rocker switches. The technical solution of this invention utilizes two needle cylinders that alternately extend and retract to achieve the rocker switch's toggle operation. The structure is simple and compact, and it is flexible and convenient to use. Furthermore, the two needle cylinders are controlled only by the energization and de-energization of a solenoid valve, resulting in a simple control circuit, stable operation, and low testing cost. It also ensures the toggle frequency of the rocker switch, improving testing efficiency. In particular, it can meet the durability testing needs of motorcycle manufacturers for engine kill switches in a simpler way.

[0034] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0035] [Example]

[0036] Combination Figure 1 and Figure 2As shown, this embodiment of a durability testing device for a rocker switch includes a switch clamp 1, a switch actuation mechanism, and a control box 6. The switch clamp 1 is used to fix the rocker switch, thereby fixing the rocker switch to be tested. The switch actuation mechanism includes a needle cylinder A2 and a needle cylinder B3, which are respectively positioned opposite to the two ends of the button on the rocker switch on the switch clamp 1. The needle cylinders A2 and B3 are respectively connected to a solenoid valve 5 through an air pipe 4. The solenoid valve 5 controls the needle cylinders A2 and B3 to alternately extend and retract to actuate the button of the rocker switch. The control box 6 contains a counting circuit for controlling the operation of the solenoid valve 5. During operation, the air circuit is connected, and the rocker switch to be tested is mounted and clamped on switch fixture 1. Then, a counting circuit controls the energization or de-energization of the solenoid valve, thereby controlling the alternating extension and retraction of needle cylinders A2 and B3. This alternating action presses both ends of the rocker switch button, repeatedly driving the rocker switch to switch positions. Each switch is counted, allowing the maximum number of times the rocker switch can be toggled to be determined. Alternatively, the rocker switch can be connected to a test circuit for live testing. When the rocker switch reaches its lifespan and fails, an alarm will sound and the test and counting will stop automatically. This durability testing device utilizes the alternating extension and retraction of two needle cylinders to achieve the rocker switch's toggle operation. It features a simple and compact structure, is flexible and convenient to use, and the two needle cylinders are controlled only by the energization and de-energization of the solenoid valve. The control circuit is simple, the operation is stable, and the testing cost is low. It also ensures the rocker switch's toggle frequency, improving testing efficiency. In particular, it provides a simpler way to meet the durability testing needs of motorcycle manufacturers for turn-off switches.

[0037] Reference Figure 1 As shown, in this embodiment, the switch clamp 1 is mounted on the control box 6, with the rocker switch button facing upwards. Needle cylinders A2 and B3 are fixedly mounted on the control box 6 via brackets 7, with the piston rods of both cylinders facing downwards. Integrating the switch clamp 1 and the switch actuation mechanism onto the control box 6 provides a strong overall structure and facilitates the movement and use of the testing device. Furthermore, the lower ends of the piston rods of both cylinders A2 and B3 are equipped with protective sleeves made of soft rubber. These sleeves contact the rocker switch, preventing damage and making the testing process more closely resemble a finger-pressing operation, thus closely mimicking the real-world use of the rocker switch and improving the accuracy of the test data.

[0038] catch Figure 1As shown, the aforementioned bracket 7 includes a vertical rod 7-1, a horizontal rod 7-2, and a right-angle connector 7-3. The vertical rod 7-1 is fixedly installed on both sides of the control box 6. The two ends of the horizontal rod 7-2 are respectively fixedly connected to the corresponding ends of the vertical rod 7-1 via the right-angle connector 7-3. Needle cylinders A2 and B3 are respectively fixed to the horizontal rod 7-2. The vertical rod 7-1, horizontal rod 7-2, and right-angle connector 7-3 can all be made of aluminum. The vertical rod 7-1 is fixed to the control box 6 with bolts, and the right-angle connector 7-3 is also fixed to the vertical rod 7-1 and the horizontal rod 7-2 with bolts. The bracket 7 has an overall assembled gantry structure, which is simple in structure, easy to manufacture, and reduces manufacturing costs.

[0039] Further reference Figure 1 As shown, in this embodiment, the switch clamp 1 includes an L-shaped fixed base 1-1, a movable clamping block 1-2, an adjusting screw 1-3, and an adjusting handwheel 1-4. The movable clamping block 1-2 is positioned opposite to the vertical portion 1-1a of the L-shaped fixed base 1-1, forming a clamping space for holding the rocker switch. The adjusting screw 1-3 is threadedly connected to one end of the L-shaped fixed base 1-1 away from the vertical portion 1-1a. One end of the adjusting screw 1-3 is rotatably engaged with the movable clamping block 1-2, and the other end of the adjusting screw 1-3 is connected to the adjusting handwheel 1-4. By rotating the adjusting handwheel 1-4, the movable clamping block 1-2 moves relative to the vertical portion 1-1a of the L-shaped fixed base 1-1, thereby changing the size of the clamping space. In use, the rocker switch is placed in the clamping space, and the adjusting screw 1-3 is rotated by the adjusting handwheel 1-4, causing the adjusting screw 1-3 to move axially together with the movable clamping block 1-2, thereby clamping and fixing the rocker switch. The clamp has a simple structure, can stably clamp the rocker switch, and the clamping operation is convenient and quick.

[0040] like Figure 2As shown, in this embodiment, the counting circuit includes an AC-DC power module 8, a dual-time relay 9, a counter 10, and an intermediate relay 11. The AC-DC power module 8 is electrically connected to the solenoid valve 5 via the dual-time relay 9, and is used to control the solenoid valve 5 to be energized or de-energized. The counter 10 is connected in parallel with the dual-time relay 9, and the intermediate relay 11 is connected in parallel with the solenoid valve 5, and the intermediate relay 11 is communicatively connected to the counter 10. The AC-DC power module 8, the dual-time relay 9, the counter 10, and the intermediate relay 11 are all commercially available products. The AC-DC power module 8 can convert 220V AC power to 12V DC power, and the operating voltage of the dual-time relay 9, the counter 10, and the intermediate relay 11 is all 12V. The above circuit structure is simple, requires no chip control, and operates stably and reliably. During operation, the AC-DC power module 8 is powered on, converting AC power into DC power. The dual-time relay 9 has two independent timing units. When timing unit A is energized, the solenoid valve 5 controls the needle cylinder A2 to extend; when timing unit B is energized, the solenoid valve 5 controls the needle cylinder B3 to extend. Simultaneously, when either timing unit A or timing unit B is energized, the intermediate relay 11 is energized and outputs a signal. The counter 10 counts once upon receiving the signal from the intermediate relay 11, and this cycle repeats. When the rocker switch malfunctions, the test stops, and the value on the counter 10 is recorded. Specifically, in this embodiment, solenoid valve 5 includes solenoid valve A and solenoid valve B, and air pipe 4 includes air pipe A and air pipe B. The air inlet pipe is connected to solenoid valve A and solenoid valve B respectively through a three-way connector. Solenoid valve A is connected to needle cylinder A2 through air pipe A, and solenoid valve B is connected to needle cylinder B3 through air pipe B. Both needle cylinder A2 and needle cylinder B3 are self-rebound needle cylinders. Solenoid valve A and solenoid valve B are alternately energized, thereby realizing the alternating extension and retraction of needle cylinder A2 and needle cylinder B3. With the above design, the air circuit connection is simple and the action response is fast.

[0041] like Figure 1 As shown, in this embodiment, the counting circuit also includes a power switch 12 and a pause switch 13 mounted on the control box 6. The power switch 12 is used to control the circuit switching of the entire testing device and can be connected to the input terminal of the AC-DC power module 8. The pause switch 13 is used to interrupt the testing process and can be connected to the control terminal of the solenoid valve 5. Both the power switch 12 and the pause switch 13 are mounted in easily accessible locations on the control box 6, facilitating pauses or shutdowns for debugging during the testing process, and making the use safer.
