Description

Vacuum cleaner motor mounting structure Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and more specifically to the motor mounting structure of a vacuum cleaner. Background Technology

[0002] Vacuum cleaners contain motors. To reduce the impact of motor operation on the vacuum cleaner, especially the impact of motor vibration, shock-absorbing structures are installed on the motor. The most common shock-absorbing structure is a shock-absorbing pad.

[0003] Most vacuum cleaners on the market use a split-type structure for motor vibration damping and fixing, rather than a blind-installation method. The main reason for this is that without a visual aid, it is difficult to install the vacuum cleaner motor in the correct position. Therefore, blind installation is difficult and inconvenient for personnel to install, so a split-type structure is the only option for fixing the vacuum cleaner motor vibration damping. Summary of the Invention

[0004] In view of this, the present invention provides a motor mounting structure for a vacuum cleaner.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a motor mounting structure for a vacuum cleaner, comprising: a housing and a motor, the motor having a first end face, a shock-absorbing pad mounted on the first end face, the housing having a mounting cavity, the inner bottom wall of the mounting cavity having a first protruding rib, the first protruding rib being arranged in a ring and protruding towards the opening of the mounting cavity, the first protruding rib forming a slot; the first protruding rib having a locking position;

[0006] The shock-absorbing pad is provided with a first protrusion, which protrudes away from the first end face; the shock-absorbing pad is provided with a locking protrusion;

[0007] The motor is assembled in the mounting cavity, the first boss is inserted into the slot, and the locking protrusion is engaged in the locking position;

[0008] In this technology, during assembly, the shock-absorbing pad is pre-installed on the first end face of the motor. When the motor is installed in the mounting cavity, the end of the motor with the first end face first enters the mounting cavity, the first boss is inserted into the slot for positioning, and the locking protrusion is locked into the locking position, so that the motor is installed in the mounting cavity at the correct angle, realizing the "blind installation" of the motor in the mounting cavity, which is convenient and quick.

[0009] As a preferred embodiment of this utility model, the inner bottom wall of the mounting cavity is further provided with a protruding post, which is located in the slot and protrudes towards the opening of the mounting cavity;

[0010] The first boss is provided with a socket, and the protrusion is inserted into the socket;

[0011] In this technology, the first boss is inserted into the slot and the protrusion is inserted into the socket, allowing them to be plugged into each other, resulting in more stable installation.

[0012] In a preferred embodiment of this utility model, the protruding post is higher than the first protruding bone. In this technology, during assembly, the protruding post first enters the insertion hole, and the shock-absorbing pad rotates while the motor is rotated until the protruding post corresponds to the locking position. Then, the protruding post is pushed into the locking position to complete the installation. At the same time, the motor is assembled in the mounting cavity at the correct angle, making the installation convenient and quick.

[0013] As a preferred embodiment of this utility model, the locking position is opened from the end face of the first protruding bone towards the inner bottom wall. Therefore, during the process of assembling the motor into the mounting cavity, the protruding bone can be pushed into the locking position.

[0014] As a preferred embodiment of this utility model, the card slot is V-shaped; the card protrusion is V-shaped; this technology defines the shape of the card slot and the card protrusion, and the V-shaped design makes it easier for the card protrusion to be inserted into the card slot.

[0015] As a preferred embodiment of the present invention, the shock-absorbing pad is provided with a first surface, and the first boss is provided on the first surface;

[0016] The locking protrusion is disposed on the first surface, or the locking protrusion is disposed on the peripheral side of the first boss; the setting position of the locking protrusion is specifically defined in this technology. Whether it is disposed on the first surface of the shock-absorbing pad or on the peripheral side of the first boss, the locking protrusion can be smoothly locked into the locking position.

[0017] As a preferred embodiment of this utility model, the first protruding bone is symmetrically provided with two locking positions; the shock-absorbing pad is correspondingly provided with two locking protrusions.

[0018] As a preferred embodiment of this utility model, the shock-absorbing pad is installed on the first end face of the motor by at least one of the following methods: snap-fit, plug-in, snap-on, and screw-locking.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] The motor mounting structure of the vacuum cleaner, as shown in Figures 1-4, includes: a housing 100 and a motor 200. The motor 200 has a first end face 201, on which a shock-absorbing pad 300 is mounted. The housing 100 is provided with a mounting cavity 101. The inner bottom wall 1011 of the mounting cavity 101 is provided with a first protrusion 110. The first protrusion 110 is arranged in a ring and protrudes towards the opening of the mounting cavity 101. The first protrusion 110 surrounds and forms a slot 120. The first protrusion 110 is provided with a locking position 111.

[0030] The shock-absorbing pad 300 is provided with a first protrusion 310, which protrudes in a direction away from the first end face 201; the shock-absorbing pad 300 is provided with a retaining protrusion 320;

[0031] The motor 200 is assembled in the mounting cavity 101, the first boss 310 is inserted into the slot 120, and the locking protrusion 320 is engaged in the locking position 111.

[0032] In this technology, the shock-absorbing pad 300 is first installed on the motor 200, and then assembled together with the motor 200 in the mounting cavity 101; the shock-absorbing pad 300 mainly plays a buffering role, reducing the transmission of motor vibration force to the outer shell 100.

[0033] During installation, the first end face 201 of the motor 200 first enters the mounting cavity 101, as shown in Figure 1. The motor 200, together with the shock-absorbing pad 300, is assembled into the mounting cavity 101 from top to bottom; the first end face 201 of the motor 200 faces downward.

[0034] The first protrusion 310 of the shock-absorbing pad 300 is inserted into the slot 120. At this time, if the locking protrusion 320 and the locking position 111 are not aligned, the motor 200 is rotated, and the shock-absorbing pad 300 rotates with the motor 200 until the locking protrusion 320 and the locking position 111 correspond. Then the locking protrusion 320 is locked into the locking position 111, and the motor 200 is installed in the housing 100, realizing "blind installation". It does not require the user to visually align the installation. The locking protrusion 320 and the locking position 111 cooperate to play a guiding and limiting role, so that the motor 200 is installed in the assembly position at the correct angle.

[0035] Furthermore, while rotating the motor 200, a downward thrust is applied to the motor 200 as shown in Figure 4. When the cam 320 and the slot 111 are aligned, the cam 320 is directly pushed into the slot 111 to complete the rapid assembly.

[0036] During the assembly of the motor 200 and the shock-absorbing pad 300 into the mounting cavity 101, the motor 200 and the shock-absorbing pad 300 need to be rotated so that the locking protrusion 320 and the locking position 111 correspond. Therefore, the inner wall surface of the first protrusion 110 is arc-shaped, and the peripheral side surface of the first protrusion 310 is also arc-shaped, so that the first protrusion 310 can rotate in the slot 120.

[0037] Furthermore, the outer casing 100 can be a component of a vacuum cleaner, as long as the inner part of the outer casing 100 can form an mounting cavity 101 for assembling the motor 200. The specific shape and structure of the outer casing 100 are not limited.

[0038] In addition, the outer casing 100 is set to be opaque.

[0039] Furthermore, a mounting cavity 101 is formed within the outer casing 100. The mounting cavity 101 has an opening 1012, as shown in FIG1. ​​The motor 200 enters the mounting cavity 101 through the opening 1012. The mounting cavity 101 is cylindrical, and the motor 200 has a corresponding arc-shaped sidewall. After the motor 200 is assembled into the mounting cavity 101, the arc-shaped sidewall is close to the inner wall of the mounting cavity 101. In this way, after the motor 200 enters the mounting cavity 101, the first boss 310 and the slot 120 can be initially aligned relatively accurately, ensuring that the first boss 310 can be inserted into the slot 120.

[0040] In one embodiment, the inner bottom wall 1011 of the mounting cavity 101 is further provided with a protrusion 130, the protrusion 130 is located in the slot 120, and the protrusion 130 protrudes in the direction of the opening of the mounting cavity 101; the first boss 310 is provided with a socket 311, and the protrusion 130 is inserted into the socket 311.

[0041] This technology achieves bidirectional insertion by inserting the protrusion 130 into the socket 311 and the first protrusion 310 into the slot 120, making the assembly more stable.

[0042] Furthermore, the protruding post 130 is higher than the first protruding bone 110. During the installation process, the protruding post 130 is first inserted into the insertion hole 311, and then the first protrusion 310 is inserted into the slot 120 for initial insertion. Finally, the motor 200 is rotated to drive the shock-absorbing pad 300 to rotate, pushing the locking protrusion 320 into the locking position 111.

[0043] The protrusion 130 is located at the center of the slot 120, and one protrusion 130 is provided. Correspondingly, one insertion hole 311 is provided.

[0044] Optionally, the number of protrusions 130 can be changed. For example, if there are three protrusions 130, then there are three sockets 311 accordingly.

[0045] Optionally, the protrusion 130 can be cylindrical or frustoconical, and the socket 311 can be modified accordingly based on the shape of the protrusion 130.

[0046] In one embodiment, the locking position 111 is opened from the end face of the first protrusion 110 toward the inner bottom wall 1011, and the locking position 111 is V-shaped; the locking protrusion 320 is V-shaped.

[0047] This technology defines the shape of the locking position 111 and the locking protrusion 320, and the V-shaped structure better guides the locking protrusion 320 into the locking position 111.

[0048] In one embodiment, the shock-absorbing pad 300 is provided with a first surface 301, and the first boss 310 is provided on the first surface 301; the locking protrusion 320 is provided on the first surface 301, or the locking protrusion 320 is provided on the peripheral side of the first boss 310.

[0049] In this technology, the protrusion 320 can be set in two ways: the first way is to directly form it on the first surface 301, and the second way is to directly form it on the peripheral side of the first protrusion 310. Both ways are acceptable.

[0050] Both of the above methods can be used to insert the protrusion 320 into the slot 111.

[0051] As shown in Figure 2, there is also a third method, in which the protrusion 320 is disposed on the first surface 301, and the sidewall of the protrusion 320 is connected to the peripheral side of the first boss 310; this method can reduce the deformation of the protrusion 320.

[0052] In one embodiment, the first convex bone 110 is symmetrically provided with two locking positions 111; the shock-absorbing pad 300 is correspondingly provided with two locking protrusions 320;

[0053] This technology designs two locking positions 111 and two locking protrusions 320, which are symmetrically distributed. During installation, if the locking protrusion 320 is not aligned with the locking position 111, the locking protrusion 320 is supported on the end face of the first protrusion 110. During the rotation of the shock-absorbing pad 300, the locking protrusion 320 moves along the end face of the first protrusion 110. The two locking protrusions 320 are symmetrically arranged to ensure the stable rotation of the shock-absorbing pad 300.

[0054] In one embodiment, the shock-absorbing pad 300 is installed on the first end face 201 of the motor 200 by at least one of the following methods: snap-fit, plug-in, snap-on, and screw-locking.

[0055] In this technology, as shown in Figure 1, the first end face 201 of the motor 200 is provided with a protrusion, and the bottom surface of the shock-absorbing pad 300 (the side opposite to the first surface 301) is provided with a corresponding groove, and the protrusion and the groove are inserted into each other.

[0056] The shock-absorbing pad 300 can also be further limited to the motor 200 by tightening screws.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
