DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Embodiment:
[0027] Please refer to Figures 1-4, this embodiment provides a shock-absorbing and anti-collision structure for a tubular motor circuit board, including a tubular motor body 1. The tubular motor body 1 includes a steel pipe 2 and a battery pack 3. A detachable shock absorber 4 is installed on the battery pack 3. A circuit board 5 is installed inside the steel pipe 2. The circuit board 5 can be clamped inside the shock absorber 4. The shock absorber 4 is inserted into the inside of the steel pipe 2 and can be fixed on the inner side wall of the steel pipe 2 by rotation. When this tubular motor circuit board shock-absorbing and anti-collision structure is in use, by installing the shock absorber 4 on the battery pack 3 and it can be disassembled. At the same time, one end of the circuit board 5 is installed inside the shock absorber 4. After inserting the shock absorber 4 into one end inside the steel pipe 2 by using the battery pack 3 and then rotating it, the shock absorber is installed on the inner side wall of the steel pipe. When the battery pack collides, the battery pack hits the shock-absorbing part and acts on the inner wall of the steel pipe 2. At this time, it will not affect the solder feet of the circuit board 5, so as to better achieve the effect of shock absorption and anti-collision for the circuit board 5, and avoid motor failures caused by damage to the solder joints of the circuit board 5 due to collision.
[0028] In this embodiment, as Figure 2 shown, a threaded ring 31 is fixedly installed on the top of the battery pack 3. The shock absorber 4 is installed on the top of the battery pack 3 located on the threaded ring 31. An internal thread is opened at the bottom of the inner side surface of the shock absorber 4 and is threadedly connected with the threaded ring 31. When the threaded ring 31 rotates counterclockwise, it is in a tightened state with the shock absorber 4. This structure is to effectively prevent the threaded ring 31 and the shock absorber 4 from loosening during the subsequent rotation of the shock absorber 4 inside the steel pipe 2.
[0029] In this embodiment, as Figure 1 and Figure 2 shown, limiting card slots 41 are symmetrically opened at both ends of the inner side edge of the top of the shock absorber 4. The size of the limiting card slots 41 matches the size of one end of the circuit board 5. Two corners of one end of the circuit board 5 are respectively inserted and clamped inside the two limiting card slots 41. This structure realizes the installation of the circuit board 5 on the shock absorber 4, so that the shock absorber 4 plays a role in shock absorption for the circuit board 5.
[0030] In this embodiment, as Figure 1 and Figure 2 shown, sliding grooves 42 are symmetrically opened on both sides of the outer ring surface of the shock absorber 4. Rotating card slots 43 are respectively opened on one side of the outer ring surface of the shock absorber 4 in the opposite direction of the two sliding grooves 42. The size of the sliding grooves 42 matches the size of the protrusions formed by the inner grooves 21 on the inner side wall of the steel pipe 2. And after the shock absorber 4 is inserted into the inside of the steel pipe 2, the two sliding grooves 42 can be respectively inserted onto the two protrusions. At this time, when the shock absorber 4 is rotated counterclockwise, the protrusions can be squeezed into the rotating card slots 43 and slide to the inner end of the rotating card slots 43, so as to clamp the shock absorber 4 on the inner side wall of the steel pipe 2, realizing that the collision force received by the shock absorber 4 acts on the inner wall of the steel pipe 2.
[0031] In this embodiment, as Figure 3 andFigure 4 As shown, a ring 6 is slidably mounted on the inner side wall of the steel pipe 2. A rubber seat 61 is mounted inside the ring 6. A spring 62 fixedly connected to the inner side surface of the ring 6 is mounted in each of the four vertical directions on the outer ring surface of the rubber seat 61. A support plate 63 is rotatably mounted inside the rubber seat 61. Two clamping blocks are symmetrically mounted at both ends of the top of the support plate 63. The tail end of the circuit board 5 matches the inner size of the rubber seat 61, and two slots matching the size of the clamping blocks are formed at the tail end of the circuit board 5. After the tail end of the circuit board 5 is inserted into the inner side of the rubber seat 61, it fits against the top of the support plate 63 and the slots are respectively clamped on the two clamping blocks. This structure realizes the shock absorption effect on the tail end of the circuit board 5 on the one hand. On the other hand, when the shock absorber 4 is rotated, the circuit board 5 will also rotate. At this time, the tail end of the circuit board 5 will drive the support plate 63 to rotate, thereby reducing the torque received by the circuit board 5 when the shock absorber 4 rotates.
[0032] Working principle: When the tubular motor circuit board shock absorption and anti-collision structure is in use, first insert the two corners at one end of the circuit board 5 into the two limit slots 41 inside the shock absorber 4. Then insert the other end of the circuit board 5 into the inner side of the rubber seat 61, and make the slots respectively form a clamping connection with the two clamping blocks. At this time, insert the shock absorber 4 into the inner side of one end of the steel pipe 2 through the battery pack 3, and align the two rotation slots 43 on the shock absorber 4 with the protrusions formed by the inner grooves 21 on the inner wall of the steel pipe 2 and insert them. At this time, rotate the shock absorber 4 counterclockwise, and the protrusion can be squeezed into the rotation slot 43 and slide to the inner end of the rotation slot 43, thereby clamping the shock absorber 4 on the inner side wall of the steel pipe 2, so that the collision force received by the shock absorber 4 acts on the inner wall of the steel pipe 2. When the battery pack collides, the battery pack collides with the shock-absorbing member and the force acts on the inner wall of the steel pipe 2. At this time, it will not affect the solder feet of the circuit board 5, so that the shock absorption and anti-collision effect on the circuit board 5 can be better achieved, and the motor failure caused by the damage of the solder joints of the circuit board 5 due to collision can be avoided.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
