Description

Technical Field

[0001] This application belongs to the field of power tool technology, specifically relating to a tiling device. Background Technology

[0002] The pavers currently on the market mainly use rubber suction cups on the bottom shell to hold the tiles in place, and rely on the motor to drive the eccentric wheel to vibrate continuously to achieve a tight fit between the tiles and the cement surface. Therefore, the vibration of the bottom shell is very large. In addition, the handle and housing of conventional pavers are directly connected to the battery pack. The battery pack is used under high-frequency vibration for a long time, which causes the battery pack structure to loosen, resulting in battery pack failure or poor connection, and also greatly reduces the service life of the battery pack.

[0003] Therefore, it is necessary to provide a tiling device to address the aforementioned technical problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0047] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0050] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0051] Reference Figure 1 , Figure 2As shown, the tiling device in this application may include a housing 1, a battery assembly 2, a connector, a bottom shell 6, a suction cup 7, a striking block, and a motor. The battery assembly 2 is used to fix the battery pack 8, and the battery assembly 2 is separate from the housing 1; the connector elastically connects the housing 1 and the battery assembly 2; the bottom shell 6 is fixedly installed on the end of the housing 1 away from the battery assembly 2; the suction cup 7 is installed on the bottom shell 6; the motor is fixedly installed in the bottom shell 6; the striking block is disposed in the bottom shell 6 and fixedly installed with the output shaft of the motor, and the striking block is driven by the motor to rotate axially along the output shaft of the motor. The striking block in this application may use a structure such as an eccentric wheel. When the striking block rotates axially along the output shaft of the motor, the side wall of the striking block continuously strikes the bottom shell 6, and the bottom shell 6 generates high-frequency vibration. This vibration is transmitted to the suction cup to facilitate tiling.

[0052] By using connectors to elastically connect the housing 1 and the battery assembly 2, the elasticity of the connectors themselves can suppress some of the vibration transmitted from the housing 1 to the battery assembly 2, thereby playing a role in shock absorption. This prevents the battery pack 8 installed on the battery assembly 2 from failing or having poor connections, and at the same time extends the service life of the battery pack 8, thereby improving the service life of the entire machine.

[0053] Specifically, in order to elastically connect the housing 1 and the battery assembly 2 via the connector, refer to Figure 3 , Figure 4 As shown, the connector in this embodiment may include a first connector 3. The first connector 3 may include a first mounting portion 31 fixedly mounted on the inner wall of the housing 1, a second mounting portion 32 fixedly mounted on the inner wall of the battery assembly portion 2, and a first connecting portion 33 connecting the first mounting portion 31 and the second mounting portion 32. The first connector 3 may be a spring sheet, which is formed into a specific shape by stamping.

[0054] In this embodiment, the first connector 3 is a metal connector. Metal has good elasticity and strength, which can effectively suppress vibration. For example, the metal connector can be a spring steel connector, a stainless steel connector, or a copper alloy connector, etc.

[0055] For example, in order to achieve the fixed installation of the first mounting part 31 and the housing 1, and the fixed installation of the second mounting part 32 and the second mounting post 21, refer to Figure 3As shown, in this embodiment, the inner wall of the housing 1 may be provided with a first mounting post 11 that cooperates with the first mounting part 31, and the inner wall of the battery assembly part 2 may be provided with a second mounting post 21 that cooperates with the second mounting part 32. Compared with the first mounting groove that directly mates with the first mounting part 31 on the inner wall of the housing 1 in other embodiments, the second mounting groove that directly mates with the second mounting part 32 on the inner wall of the battery assembly part 2 has a larger contact area between the first mounting post 11 and the first mounting part 31 and the second mounting post 21 and the second mounting part 32 in this embodiment, which can clamp tightly, prevent loosening, and resist shock and loosening.

[0056] It should be noted that, compared to designs where both the first mounting portion 31 and the second mounting portion 32 are straight strips, the cross-section of the first mounting portion 31 and / or the second mounting portion 32 in this application is an open annular. For example, see... Figure 3 As shown, in this embodiment, the cross-sections of the first mounting portion 31 and the second mounting portion 32 are both open annular, while the cross-section of the first connecting portion 33 is straight. The cross-section of the first mounting portion 31 can be C-shaped or U-shaped, etc. The cross-section of the second mounting portion 32 can be C-shaped or U-shaped, etc. According to this design, the first mounting portion 31 and the second mounting portion 32 can form a semi-closed structure, which can achieve radial constraint to generate a continuous clamping force. Through their own structural characteristics, they are reliably and securely installed on the first mounting post 11 and the second mounting post 21, respectively, without the need for additional drilling at both ends of the first connecting member 3 and the use of fasteners for fixed installation.

[0057] To prevent relative rotation between the first connecting piece 3 and the housing 1, refer to... Figure 3 As shown, in this embodiment, the inner wall of the housing 1 may be provided with a first limiting plate 12 connected to the first mounting post 11. The first limiting plate 12 and the first mounting post 11 enclose to form a first limiting groove 100. The first mounting part 31 is fixedly installed in the first limiting groove 100, which can also prevent relative rotation between the first connecting member 3 and the housing 1. It should be noted that when the first limiting groove 100 is provided, the cross-sectional shape of the first mounting post 11 can be any shape and is not limited. Of course, this application is not limited to this. In other embodiments, when the cross-sectional shape of the first mounting post 11 is not circular, the first limiting groove 100 may or may not be provided. Geometric constraints are used to suppress relative rotation between the first connecting member 3 and the housing 1.

[0058] To prevent relative rotation between the first connector 3 and the battery assembly 2, refer to... Figure 3As shown, the cross-sectional shape of the second mounting post 21 in this embodiment can be non-circular. Geometric constraints are used to suppress relative rotation between the first connector 3 and the battery assembly 2. The second limiting groove 200 is not provided. However, this application is not limited to this; see also... Figure 5 As shown, in other embodiments, a second limiting plate 22 connected to the second mounting post 21 may be provided on the inner wall of the battery assembly part 2. The second limiting plate 22 and the second mounting post 21 enclose a second limiting groove 200, and the second mounting part 32 is fixedly installed in the second limiting groove 200, which can also prevent relative rotation between the first connecting member 3 and the battery assembly part 2. It should be noted that when the second limiting groove 200 is provided, the cross-sectional shape of the second mounting post 21 can be any shape without restriction.

[0059] Preferably, in order to further reduce the vibration transmitted from the housing 1 to the battery assembly 2, refer to Figure 3 As shown, in this embodiment, a second shock absorber 9 may be provided between the second mounting portion 32 and the second mounting post 21. Of course, in other embodiments, only the first shock absorber may be provided between the first mounting portion 31 and the first mounting post 11; or, the first shock absorber may be provided between the first mounting portion 31 and the first mounting post 11, while the second shock absorber 9 may be provided between the second mounting portion 32 and the second mounting post 21. The first and second shock absorbers 9 may be made of flexible materials with elasticity, such as latex or silicone.

[0060] To strengthen the connection between the housing 1 and the battery assembly 2 and to further reduce the vibration transmitted from the housing 1 to the battery assembly 2, refer to Figure 2 , Figure 3 As shown, the connector in this embodiment may include a second connector 4. The second connector 4 may include a first main body portion 41 covering the outer wall of the housing 1, a second main body portion 42 covering the outer wall of the battery assembly portion 2, and a second connecting portion 43 connecting the first main body portion 41 and the second main body portion 42. The second connector 4 is a flexible connector. The second connector 4 may be made of rubber, or it may be made of other flexible materials, such as latex, silicone, or other readily available elastic flexible materials.

[0061] Preferably, refer to Figure 3 As shown, in this embodiment, the second connecting portion 43 at least partially extends into the gap between the housing 1 and the battery assembly portion 2, and the second connecting portion 43 abuts against both the housing 1 and the battery assembly portion 2. The high elasticity and buffering performance of the elastic second connecting portion 4 are utilized to absorb vibration energy, achieving a shock absorption effect.

[0062] It should be noted that since both the housing 1 and the battery assembly 2 are plastic shells, they can be injection molded separately or in a single injection molding process. When injection molded separately, the housing 1 and battery assembly 2 are separated from the start. When injection molded in a single process, a runner is provided between the two cavities in the injection mold to allow molten plastic to flow into the two cavities to form the housing 1 and battery assembly 2 respectively. After complete cooling and demolding, the molten plastic in the runner becomes a plastic strip connecting the housing 1 and battery assembly 2. This plastic strip can be removed or retained. When the plastic strip is removed, the housing 1 and battery assembly 2 separate. When the plastic strip is retained, the housing 1 and battery assembly 2 are partially connected through the plastic strip.

[0063] When the housing 1 and the battery assembly 2 are separated, the connector can be the first connector 3, or the second connector 4, or a combination of the first connector 3 and the second connector 4.

[0064] When the plastic strip is retained, it serves as the third connector 5. When vibration is transmitted from the housing 1 to the battery assembly 2, if the connection strength between the housing 1 and the battery assembly 2 formed by the third connector 5 is too low to restrict a stable connection between the housing 1 and the battery assembly 2, only by providing another connector (the first connector 3, or the second connector 4, or a combination of the first connector 3 and the second connector 4) can it be ensured that the housing 1 and the battery assembly 2 will not break.

[0065] When the connection strength between the housing 1 and the battery assembly 2 formed by the third connector 5 is sufficient, the connection between the housing 1 and the battery assembly 2 can be achieved simply by using the third connector 5. Of course, furthermore, to make the connection strength between the housing 1 and the battery assembly 2 even greater, in addition to providing the third connector 5, a first connector 3, a second connector 4, or a combination of the first connector 3 and the second connector 4 can also be provided.

[0066] Reference Figure 3 As shown, when the plastic strip is retained, the connector includes a third connector 5 disposed in the gap between the housing 1 and the battery assembly 2, with both ends of the third connector 5 fixedly installed to the housing 1 and the battery assembly 2, respectively. When the connection strength between the two ends of the third connector 5 and the housing 1 and the battery assembly 2 is sufficient, the housing 1 and the battery assembly 2 can be elastically connected through the third connector 5.
