Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Examples, such as Figures 1-7As shown, this utility model provides a pipe-type vibration-damping and sound-insulating motor mount, including a motor mount housing 4. The motor mount housing 4 is used to install a motor 3 inside it. A sound insulation cover 5 is provided between the inner wall of the motor mount housing 4 and the motor 3. A support frame 9 is provided inside the sound insulation cover 5 to prevent the sound insulation cover 5 from collapsing. Both the sound insulation cover 5 and the motor mount housing 4 have holes for the output end of the motor 3, i.e., the extension of the transmission rod 2. By setting up the sound insulation cover 5, noise can be reduced; the support frame 9 improves the structural strength of the sound insulation cover 5, ensuring the overall shape of the sound insulation cover 5 and the connection between the upper and lower parts, thus ensuring the sound insulation effect of the sound insulation cover 5 to a certain extent, thereby achieving the purpose of sound insulation.

[0029] For ease of assembly, the motor housing 4 provided by this utility model includes an upper housing 41 and a lower housing 42. The upper housing 41 is inverted U-shaped, and the lower housing 42 is groove-shaped and has an opening that corresponds to and engages with the upper housing 41. The upper housing 41 is fastened to the opening of the lower housing 42 from top to bottom, and the mating surfaces of the upper housing 41 and the lower housing 42 are continuous and closed sealing edges.

[0030] To improve the fit between the upper housing 41 and the lower housing 42, the upper housing 41 of this invention has extensions 8 at both ends that mate with the lower housing 42. The bottom of both sides of the upper housing 41 has protrusions 10, and both sides of the lower housing 42 have slots 11 that mate with the protrusions 10. In this way, the top edge of the lower housing 42 rests against the bottom surface of the extensions 8, and the protrusions 10 are fastened to the slots 11, thus forming a continuous and closed sealing edge and quickly establishing a stable connection, improving the efficiency of installing the device onto the corresponding position on the study desk. Furthermore, the shape design of the upper housing 41 and the lower housing 42, combined with the fit between the protrusions 10 and the slots 11, [further details about the design and fit are needed for a complete translation].

[0031] Furthermore, the longitudinal section of the boss 10 provided by this utility model is semi-circular. During the process of the boss 10 being inserted into the slot 11 from top to bottom, the distance between the two sides of the upper shell 41 undergoes a certain gradual process, thereby generating a certain elastic force until the boss 10 is inserted into the slot 11 and the fastening is completed.

[0032] For ease of assembly, the soundproof cover 5 provided by this utility model includes an upper soundproof felt 51 and a lower soundproof felt 52. Both the upper soundproof felt 51 and the lower soundproof felt 52 can be made of a single open groove with their grooves facing each other. After installation, the upper soundproof felt 51 is attached to the inner wall of the upper shell 41, and the lower soundproof felt 52 is attached to the inner wall of the lower shell 42. The lower end of the upper soundproof felt 51 is attached to the lower soundproof felt 52, thereby forming a sound isolation space that isolates noise.

[0033] To enhance the supporting effect of the support frame 9 on the soundproof cover 5, the support frame 9 provided by this utility model includes at least two end frames 91. The shape of the end frames 91 is adapted to an inner end face of the soundproof cover 5, and multiple connecting rods 92 are provided between adjacent end frames 91. The end frames 91 can adopt a loop-like design, and the endpoints of the connecting rods 92 are connected to the loop-like path of the end frames 91.

[0034] Furthermore, an elastic part 93 is provided at the position corresponding to the connecting rod 92 on the end frame 91. In this embodiment, the elastic part 93 adopts an arc-shaped design, but it can also be designed as a non-linear shape, such as V, [, γ, etc., as needed. This allows part of the pressure borne by the end frame 91 to be converted into local deformation at the location of the elastic part 93, and it has a tendency to recover, thereby ensuring that the support frame 9 can maintain a good support effect inside the upper horizontal tube 1 of the study table.

[0035] To improve the vibration damping performance of this device, the motor 3 provided in this invention is fixedly connected to the motor housing 4 by bolts. The motor housing 4 has a through hole to accommodate the bolt, and a T-shaped motor rubber pad 12 is installed at the through hole. One end of the motor rubber pad 12 extends into the through hole and is used to isolate the through hole from the bolt, while the other end of the motor rubber pad 12 is located outside the through hole and is turned outward to isolate the bolt from contact with the outer end face of the motor housing 4. By setting the motor rubber pad 12, the vibration transmission from the motor 3 to the motor housing 4 can be effectively reduced, and the noise of the bolt thread pair and the vibration of the mating clearance can be reduced, thereby improving the vibration damping performance of this device.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the motor housing 4 provided by this utility model is fixedly installed inside the upper horizontal tube 1 by fixing bolts. A motor housing nut 6, which mates with the fixing bolts, is provided at the bottom of the motor housing 4. A through hole is provided on the upper horizontal tube 1 to accommodate one end of the fixing nut, and a motor housing rubber pad 7, which is I-shaped, is provided at the through hole. By providing the motor housing rubber pad 7, the vibration transmission from the motor housing 4 to the upper horizontal tube 1 can be effectively reduced, as well as the noise and vibration of the threaded pair and clearance between the fixing bolts and the motor housing nut 6. Therefore, by providing the motor rubber pad 12 and the motor housing rubber pad 7, the isolation of the motor 3's vibration can be effectively improved, solving the problem in the prior art where the motor 3 produces significant noise and vibration when working inside the tube, thus reducing the user experience.

[0037] To improve the quick fit between the motor mount rubber pad 7 and the through hole, the outer diameter of one end of the motor mount rubber pad 7 provided by this utility model is larger than the inner diameter of the through hole and smaller than the outer diameter of the other end. This allows the motor mount rubber pad 7 to be quickly inserted into the through hole, achieving a bidirectional snap-fit ​​connection in both the inner and outer directions.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
