[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1 to 7As shown, this utility model can be implemented through the following embodiments: A life testing device for an electromagnetic brake handle 21 of a mobility scooter includes a base 1 and a brake 2 to be tested. The handle 21 is installed on the brake 2 to be tested. A fixed seat 11 is provided on the base 1. The brake 2 to be tested is installed on the fixed seat 11. A vertical plate 12 is provided on the base 1. A cylinder 3 is installed on the vertical plate 12. A U-shaped plate 4 is connected to the cylinder 3. A push-pull sensor 5 is connected to the U-shaped plate 4. An L-shaped connecting plate is installed at the other end of the push-pull sensor 5. The L-shaped connecting plate and the handle 21 are fixedly connected.

[0015] The fixed base 11 is used to position and place the brake 2 to be tested; the vertical plate 12 is used to install the cylinder 3, so that the cylinder 3 can control the reciprocating motion of the handle 21 through the connection of the U-shaped plate 4, the push-pull sensor 5 and the L-shaped connecting plate; the push-pull sensor 5 is used to record the number of reciprocating motions of the cylinder 3 to ensure data accuracy.

[0016] like Figures 1 to 3 As shown, the brake under test 2 has a groove 22, and the base 1 has a fixing groove 13. Bolt 7 is installed on the groove 22 and the fixing groove 13, and nut 71 is installed on bolt 7. Bolt 7 passes through the fixing groove 13 and the groove 22 on the brake under test 2 to limit the movement of the brake under test 2. At the same time, bolt 7 and nut 71 clamp the fixing groove 13 and the groove 22 to prevent the brake under test 2 from jumping upward during the test and causing it to fall off the fixing base 11.

[0017] like Figure 1 , Figure 3 and Figure 4 As shown, the L-shaped connecting plate 6 has a through hole 61, and the handle 21 has a through hole 211. The connecting rod 8 passes through both the through hole 61 and the through hole 211. The through holes 61 and 211, through which the connecting rod 8 passes, fix the L-shaped connecting plate to the handle 21, so that the reciprocating motion of the cylinder 3 can drive the reciprocating motion of the handle 21, thereby achieving the life test of the handle 21.

[0018] like Figure 1 , Figure 5 and Figure 7 As shown, the connecting rod 8 has a slot 81, and a retaining spring 82 is installed in the slot 81. The slot 81 and the retaining spring 82 cooperate to fix the connecting rod 8 in the through hole 61 and the through hole 211, preventing the connecting rod 8 from falling off during testing, which would prevent the cylinder 3 from driving the handle 21 to reciprocate and cause data errors.

[0019] like Figure 1 , Figure 2 and Figure 6As shown, the vertical plate 12 has a positioning hole 121, and the cylinder 3 has a fixing hole 31. A bolt 2 9 passes through the positioning hole 121 and the fixing hole 31, and a nut 2 91 is installed on the bolt 2 9. The bolt 2 9 passes through the positioning hole 121 and the fixing hole 31 and is used to adjust the position of the cylinder 3, which is convenient for testing various models of brakes 2 under test and improves the versatility of the testing equipment. The detachable structure of the bolt 2 9 and the nut 2 91 facilitates multiple adjustments to the position of the cylinder 3 and also facilitates the disassembly and assembly of the cylinder 3.

[0020] like Figure 1 and Figure 2 As shown, there are two fixed bases 11. Having two fixed bases 11 helps to increase the number of testing stations on the equipment and improve testing efficiency.

[0021] The working principle of this utility model is as follows: Place the brake to be tested 2 on the fixed base 11 and align the groove 22 with the fixed groove 13; pass the bolt 7 through the groove 22 and the fixed groove 13, and at the same time install the nut 71 on the bolt 7 at the fixed groove 13; adjust the position of the cylinder 3, align the fixed hole 31 and the positioning hole 121 on the cylinder 3 and insert the bolt 9, and at the same time install the nut 91 on the bolt 9 to fix the cylinder 3 on the vertical plate 12; at the same time, connect the U-shaped plate 4, the push-pull sensor 5 and the L-shaped connecting plate in this way; finally, align the through hole 61 on the L-shaped connecting plate with the through hole 211 on the handle 21 and insert the connecting rod 8; install the retaining spring 82 on the retaining groove 81 of the connecting rod 8 to fix the handle 21 and the L-shaped connecting plate together.

[0022] The cylinder 3 is started to reciprocate, and the push-pull sensor 5 records the reading of the reciprocating motion of the handle 21 until the handle 21 stops its normal driving function due to metal fatigue and the reading is recorded.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
