Description

Technical Field

[0001] This utility model relates to the field of motor cover technology, and more specifically, to a shock-absorbing motor cover. Background Technology

[0002] A motor cover is a protective device that is placed on the surface of a motor to prevent external factors such as dust and rain from affecting the normal rotation of the motor. When the motor is running, it will vibrate, and the high-frequency vibration of the motor will cause the motor cover to resonate.

[0003] The common method of vibration damping in motor covers is to fix several rubber gaskets inside to isolate vibration. However, the elasticity of the rubber gaskets will decrease after long-term use. Since the rubber gaskets are all located inside the motor cover, it is not easy to detect the degree of aging of the rubber gaskets, thus making it impossible to perform timely maintenance.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shock-absorbing motor cover.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The shock-absorbing motor cover includes a cover body, on the inner wall of the cover body are provided a plurality of alternately arranged buffer strips 1 and 2, the thickness of the buffer strip 1 is greater than the thickness of the buffer strip 2, a sliding groove with a cross-sectional shape of L is opened on the inner wall of the cover body, a prompting rod that abuts against the buffer strip 1 is slidably connected to the inner wall of the sliding groove, the length of the prompting rod is greater than the wall thickness of the cover body, a plurality of receiving grooves located on both sides of the length direction of the buffer strip 1 are opened on the inner wall of the cover body, a covering piece with an arc-shaped cross-section for covering the buffer strip 1 is slidably connected in the receiving groove, the elastic deformation performance of the covering piece is less than the elastic deformation performance of the buffer strip 1, and the radius of the covering piece is less than the thickness of the buffer strip 2.

[0007] The present invention is further configured such that: an elastic element for pushing the covering sheet to slide is provided in the receiving groove, and the cross-sectional shape of the receiving groove is the same as the sliding trajectory of the covering sheet.

[0008] The present invention is further configured such that: limiting plates for limiting the length of the elastic element are fixedly connected to both sides of the buffer strip in the length direction, and the elastic deformation performance of the buffer strip is the same as that of the limiting plates.

[0009] The present invention is further configured such that: the distance between the bottom surface of the limiting piece and the inner wall of the cover is less than the distance between the bottom surface of the buffer strip and the inner wall of the cover; and the supporting force of the limiting piece on the covering piece is greater than the weight of the covering piece and the elastic force of the elastic element.

[0010] The present invention is further configured such that: the adjacent covering pieces disposed on both sides of the buffer strip along a length direction are detachably connected, and the adjacent covering pieces that are close to each other are fixedly connected with magnets.

[0011] The present invention is further configured such that the end of the indicator rod furthest from the buffer strip is colored red.

[0012] In summary, this utility model has the following beneficial effects: In the initial state, several buffer strips abut against the outer peripheral wall of the motor, thereby absorbing and reducing the vibration transmitted to the motor cover. When the buffer strips directly bear the vibration force for a long time and age, their elasticity will decrease. After bearing the vibration force and deforming, their thickness will decrease and they will not rebound. At this time, the second buffer strip will replace the first buffer strip to bear the vibration force generated by the motor, thereby ensuring the shock absorption effect of the motor cover. When the first buffer strip ages, the indicator rod will pass through the sliding groove to remind the worker that the first buffer strip needs to be replaced. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] This shock-absorbing motor cover, such as Figure 1 and Figure 2As shown, the device includes a housing 1. The back plate of the housing 1 has several heat dissipation holes. During operation, the motor continuously generates heat; these holes facilitate heat dissipation, preventing excessive heat buildup inside the housing 1 and potential overheating that could damage internal components. Inside the housing 1, several alternating buffer strips 2 and 3 are arranged in an array. Both buffer strips 2 and 3 are made of rubber, utilizing the properties of rubber to provide them with good elastic deformation performance. This absorbs and disperses the vibration force transmitted from the motor to the housing 1, ensuring good shock absorption. The thickness of buffer strip 2 is greater than that of buffer strip 3. After the housing 1 is fitted onto the motor, the outer perimeter of the motor will... Applying pressure causes the buffer strip 2 to deform under compression and remain in contact with the motor. Therefore, the vibration force generated by the motor during operation is gradually dispersed by the elastic deformation performance of the buffer strip 2 itself, reducing the vibration force that can be transmitted to the cover 1. As the motor operates for longer, the buffer strip 2 will gradually age, and its elastic deformation performance will decrease. This means that after being compressed by vibration, it cannot return to its initial state. Since the thickness of the buffer strip 3 is less than that of the buffer strip 2, the buffer strip 3 bears less vibration force when the buffer strip 2 bears vibration force. Therefore, after the buffer strip 2 ages, the buffer strip 3 can replace the buffer strip 2 in dispersing the vibration force, extending the shock absorption time of the cover 1 during use.

[0017] An L-shaped sliding groove 4 is formed on the inner wall of the cover 1. A prompting rod 5, which abuts against the buffer strip 2, is slidably connected to the inner wall of the sliding groove 4. The side wall of the prompting rod 5 abuts against the side wall of the sliding groove 4, providing stable support for the horizontal sliding of the prompting rod 5. The sliding groove 4 is located on the side wall of the cover 1, which is perpendicular to the ground. Therefore, the side wall of the sliding groove 4 can also provide stable support for the prompting rod 5, preventing the prompting rod 5 from falling out of the sliding groove 4 under its own weight. The length of the prompting rod 5 is greater than the wall thickness of the cover 1. In the initial state, the side of the prompting rod 5 closest to the buffer strip 2 extends out of the sliding groove 4, and the end of the prompting rod 5 away from the buffer strip 2 is completely retracted. The indicator rod 5 is placed inside the sliding groove 4. Since the buffer element 1 can disperse most of the vibration force, the pressure on the indicator rod 5 during this process is not enough to make it pass through the sliding groove 4. When the buffer strip 2 ages, its own buffering effect decreases, so the vibration force transmitted from the motor to the buffer strip 2 increases, thus allowing more pressure on the buffer strip 2 to be transmitted to the indicator rod 5, and pushing the side of the indicator rod 5 closest to the buffer strip 2 completely into the sliding groove 4. At this time, the end of the indicator rod 5 away from the buffer strip 2 will pass through the cover 1. The color of the end of the indicator rod 5 away from the buffer strip 2 is set to red, so as to remind the worker that the buffer strip 2 has aged, making it convenient for the worker to replace it in time.

[0018] The inner wall of the cover 1 is provided with receiving grooves 6 for both sides of the buffer strip 2 along its length. Covering pieces 7 with an arc-shaped cross-section are slidably connected within the receiving grooves 6 to cover the buffer strip 2. The two covering pieces 7 on both sides of the buffer strip 2 completely cover the aging buffer strip 2. As the buffer strip 2 ages, it may crack. Due to the vibration of the motor, the cracked parts of the buffer strip 2 may break or even fall off. Therefore, the covering pieces 7 can catch the debris that is shaken off, preventing it from falling into the motor and causing damage. In the worst-case scenario, the elastic deformation performance of the covering piece 7 is less than that of the buffer strip 2. Therefore, during the sliding process of the covering piece 7, the side wall of the buffer strip 2 can provide good clearance for the sliding of the covering piece 7, preventing the covering piece 7 from being stuck by the side wall of the buffer strip 2 during the sliding process. Since the radius of the covering piece 7 is smaller than the thickness of the buffer strip 3, after the covering piece 7 completes the covering of the buffer strip 2, the covering piece 7 will apply pressure to the buffer strip 2 to reduce its thickness, thereby preventing the covering piece 7 from contacting the motor and causing it to be damaged.

[0019] The cross-sectional area of ​​the receiving groove 6 is arc-shaped, and the opening orientation is the same as the sliding trajectory of the covering piece 7, thereby guiding the sliding direction of the covering piece 7. An elastic element 8 is provided in the receiving groove 6 to push the covering piece 7 to slide. The elastic element 8 is set as a spring. In the initial state, the elastic element 8 is in a compressed state, so that one end of the covering piece 7 is located in the receiving groove 6. When the pressure on the elastic element 8 is removed, the elastic element 8 will reset under the action of its own elastic deformation performance and push the covering piece 7 to slide along the receiving groove 6. Magnet pieces 10 are fixedly connected to the sides of the necklace covering pieces 7 on both sides of the buffer strip 2 along the length direction. The attraction between the magnet pieces 10 is used to realize the detachable connection between adjacent covering pieces 7. Under the action of the magnet pieces 10, even if the pushing force applied by the elastic element 8 to the covering piece 7 is not enough to make the adjacent covering pieces 7 abut against each other, as long as the distance between the adjacent covering pieces 7 allows the adjacent magnet pieces 10 to generate attraction, the two covering pieces 7 can be stably fixed, ensuring the stable use of the structure.

[0020] The buffer strip 2 has integrally formed limiting plates 9 on both sides along its length to restrict the length of the elastic element 8. In the initial state, the covering sheet 7 abuts against the limiting plates 9. At this time, the supporting force of the limiting plates 9 on the covering sheet 7 is greater than the weight of the covering sheet 7 and the elastic force of the elastic element 8, preventing the covering sheet 7 from drooping downwards under the action of gravity. The distance between the bottom surface of the limiting plate 9 and the inner wall of the cover 1 is less than the distance between the bottom surface of the buffer strip 2 and the inner wall of the cover 1. Therefore, the bottom surface of the limiting plate 9 will not abut against the motor and will not bear the load. The large amount of vibration force from the motor ensures the stable support of the limiting piece 9 for the covering piece 7. Since the elastic deformation performance of the buffer strip 2 is the same as that of the limiting piece 9, and the limiting piece 9 is only connected to the buffer strip 2 on one side, when the buffer strip 2 shows signs of aging, its connection strength with the limiting piece 9 will also decrease. At this time, the support strength of the limiting piece 9 for the covering piece 7 will decrease, and the covering piece 7 will pass through the receiving groove 6 under the action of the elastic element 8 and cover the buffer strip 2.

[0021] Working principle: In the initial state, buffer strip 2 abuts against the motor, bearing and dispersing the vibration force from the motor. The end of the indicator rod 5 away from buffer strip 2 is housed in the sliding groove 4. When buffer strip 2 ages, it will not return to its initial state after being subjected to the vibration force that compresses it. At this time, buffer strip 3 will replace buffer strip 2 to bear and disperse the vibration force from the motor. At the same time, the vibration force on indicator rod 5 increases, so it will go along the sliding groove 4 and out of the cover 1, indicating to the worker that buffer strip 2 is aging. Meanwhile, as the connection strength between buffer strip 2 and limiting piece 9 decreases, covering piece 7 will slide under the pushing force exerted by its own weight and elastic element 8 until adjacent covering pieces 7 abut against each other through magnet piece 10, thus covering buffer strip 2.
