Description

Technical Field

[0001] The utility model relates to the technical field of motor shells, in particular to an end cover of a sonic motor which is easy to disassemble. Background Art

[0002] An acoustic motor is a motor that uses the vibration force generated by sound waves to drive rotation or linear motion. It is usually composed of components such as an acoustic wave generator and piezoelectric ceramics. Mechanical motion is achieved through the vibration force generated by sound waves in the components. When the acoustic wave motor is working, it will generate a large vibration force, so the vibration is more violent. This vibration force can be used to drive the movement of mechanical parts.

[0003] However, when using a removable sonic motor end cover, even if a waterproof ring is used to fix the screws, if the motor is subjected to long-term severe vibration, the screws may rotate in the opposite direction, causing the sealing ring to loosen and eventually lose its sealing and waterproofing function. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In order to solve the problem that under long-term severe vibration, the screw fixing part of the detachable sonic wave motor end cover may rotate in the opposite direction, causing the sealing ring to loosen and then lose the sealing and waterproof function, the utility model provides the following technical solutions: an easy-to-remove sonic wave motor end cover, comprising a cover body, and a locking range for penetrating the screw on the cover body, a sealing ring is provided on the locking range, and cooperates with the screw to fill the gap between the locking range and the sealing ring, characterized in that: the locking range has a first damping area, a second damping area, a third damping area and a fourth damping area, and any damping area is provided with a locking piece, and after tightening the screw, the damping area is squeezed into contact with the surface area of ​​the sealing ring, and the screw is squeezed and frictionally contacted with the sealing ring, so that the sealing ring and the screw are locked in the locking range.

[0006] As a preferred solution of the easily disassembled end cover of the sonic wave motor of the utility model, a locking piece is provided on the damping area, and the locking piece and the plane of the damping area form a concave-convex staggered structure.

[0007] As a preferred solution of the easily disassembled end cover of the sonic motor of the utility model, the locking member is provided with a locking notch, and the locking notch has a sharp protrusion.

[0008] As a preferred solution of the easily disassembled end cover of the sonic wave motor described in the utility model, the locking range includes the first plane, the second plane, the adapter hole, and the recess.

[0009] As a preferred solution of the easily disassembled end cover of the ultrasonic motor described in the utility model, a depression is provided between the first plane and the second plane, an adapter hole is provided at the center of the second plane to connect the through screw to the motor housing, and a sealing ring is clamped in the depression.

[0010] As a preferred solution of the easily disassembled end cover of the sonic wave motor of the utility model, the first plane, the second plane and the depression therebetween jointly form a first damping zone, a second damping zone, a third damping zone and a fourth damping zone.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 5 , which is the first embodiment of the utility model, and provides an end cover of an acoustic wave motor that is easy to disassemble, including a cover body 100, and a locking range 200 for passing a screw is provided on the cover body 100, and a sealing ring 300 is provided on the locking range 200, which cooperates with the screw to fill the gap between the locking range 200 and the sealing ring 300;

[0027] The cover body 100 refers to a detachable assembly with the motor housing, and the locking range 200 can be a groove, a protrusion or other structure opened on the cover body 100, or it can be other components, and its purpose is to cooperate with the sealing ring 300 to squeeze and cover the gap between the sealing ring 300 and the locking range 200 after the screws fasten the cover body 100 and the motor housing to achieve airtightness. At the same time, the sealing ring 300 is installed on the locking range 200, and the locking range 200 has a locking function to prevent the sealing ring 300 from rotating. The friction force generated by the extrusion of the screw and the sealing ring 300 can effectively prevent the reverse rotation of the screw when the sonic motor vibrates during operation, which leads to the problem of loosening the screw. At the same time, the installation of the sealing ring 300 can also play a certain shockproof effect;

[0028] The locking range 200 has a first damping area 200a, a second damping area 200b, a third damping area 200c and a fourth damping area 200e, and any damping area is provided with a locking member 200-1. After tightening the screw, the damping area is pressed and contacted with the surface area of ​​the sealing ring 300, and the screw is pressed and frictionally contacted with the sealing ring 300, so that the sealing ring 300 and the screw are locked on the locking range 200;

[0029] The so-called first damping zone 200a, second damping zone 200b, third damping zone 200c and fourth damping zone 200e mean that any damping zone therein can form friction resistance with the contact area of ​​the sealing ring 300, thereby preventing the sealing ring 300 and the screw from rotating in the opposite direction. The damping zone here does not refer to a single damping zone, but an arbitrary combination of four damping zones. The locking member 200-1 is combined with any damping zone to form a damping that blocks the sealing ring 300 and the screw, which has the effect of enhancing the effect of preventing the sealing ring 300 from rotating.

[0030] Example 2

[0031] Reference Figures 2 to 5 , is an embodiment of the utility model. This embodiment is different from the first embodiment in that a locking member 200-1 is provided on the damping area. The locking member 200-1 and the plane of the damping area form a concave-convex alternating structure. The locking member 200-1 can be a protrusion or a groove provided on the plane of the damping area. In this way, whether it is a protrusion or a groove and the plane, a concave-convex alternating structure can be formed, which can effectively block the sealing ring 300;

[0032] The locking members 200-1 are arranged at equal intervals on the damping area, and the locking members 200-1 are provided with locking notches 200-1a, which have sharp protrusions. When the sealing ring 300 is rotated and squeezed by the screw, the sealing ring 300 is squeezed and rotated to be recessed inside the locking member 200-1 and stuck in the locking member 200-1. At the same time, the locking notches 200-1a pierce the sealing ring 300, and the sealing ring 300 is firmly locked to prevent it from rotating in the reverse direction, thereby preventing the screw from rotating in the reverse direction due to the vibration of the motor.

[0033] like Figure 1As shown, the first plane 201, the second plane 202 and the recess 204 therebetween jointly form the first damping zone 200a, the second damping zone 200b, the third damping zone 200c and the fourth damping zone 200e. The locking range 200 includes the first plane 201, the second plane 202, the adapter hole 203 and the recess 204. A recess 204 is provided between the first plane 201 and the second plane 202. An adapter hole 203 is provided at the center of the second plane 202 to connect the through screw to the motor housing. The sealing ring 300 is clamped in the recess 204. This setting allows the sealing ring 300 and the damping zone to have more contact surfaces, thereby providing more friction resistance and blocking resistance to prevent the screw from rotating in the opposite direction.

[0034] Importantly, it should be noted that the construction and arrangement of the present application shown in a plurality of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and ratio of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present utility model. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure of performing the function described herein, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the present invention is not limited to a specific embodiment, but extends to various modifications that still fall within the scope of the appended claims.

[0035] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0036] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
