Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to rocking devices and children's products. Background Technology

[0002] Currently available children's products with rocking functions, such as baby cradles and rocking beds, mostly use a rod that can swing relative to the ground as the rocker. The rod is fixed to the ground and connected to the children's product. When the rod swings, it will push the main body of the children's product to swing. Therefore, rockers are generally large and heavy, inconvenient to install, and result in a poor user experience. Utility Model Content

[0003] Therefore, it is necessary to address the problem that the rocking devices currently available on the market are large and heavy, making them inconvenient to install and resulting in a poor user experience, and to provide a rocking device and children's products.

[0004] A rocker includes: a housing assembly; a brushless motor disposed in the housing assembly; and a counterweight disposed on the output end of the brushless motor, the center of gravity of the counterweight being offset from the rotation axis of the output end of the brushless motor, the counterweight being configured to rotate relative to the housing assembly under the drive of the brushless motor.

[0005] This application provides a rocker with a brushless motor inside its housing assembly for driving a counterweight to rotate. The center of gravity of the counterweight is offset from the rotation axis of the brushless motor's output end. Therefore, when the brushless motor starts and drives the counterweight to rotate around its output axis, it generates centrifugal force in a direction away from the rotation axis. When the rocker is connected to the rocker body, this centrifugal force causes the rocker to rock the rocker body. This device has a simple structure, effectively reducing the size of the rocker and facilitating installation and use. Furthermore, the use of a brushless motor to drive the counterweight allows for wide-range speed adjustment by adjusting the input voltage, current, or magnetic field strength, ensuring stable operation from low to high speeds. Compared to ordinary brushed motors, it eliminates the mechanical contact between the brushes and the commutator, reducing energy loss and friction noise, making it more suitable for applications with high noise control requirements, such as baby products.

[0006] In one embodiment, the brushless motor includes a stator, a rotor, and a control module. The stator is mounted on the housing assembly, and the rotor is sleeved on the outside of the stator. The rotor is connected to a counterweight, the center of gravity of which is offset from the rotation axis of the rotor. The control module is electrically connected to the stator, thereby driving the rotor to rotate the counterweight around the rotor's axis. When the stator is energized, the rotor can drive the counterweight to rotate around the rotor's axis relative to the fixed stator on its outside. By adopting the above-mentioned external rotor form, on the one hand, it is easier to connect the counterweight to the rotor; on the other hand, the external rotor has a large inertia, a robust structure, and good load-bearing capacity, making it suitable for applications with heavy loads such as those requiring counterweights.

[0007] In one embodiment, the counterweight has an annular connecting portion that is sleeved on the outside of the rotor. By employing this structure, the annular connecting portion engages with the outer peripheral wall of the rotor to create a limiting effect, thereby facilitating rapid positioning and assembly of the counterweight, and ensuring secure installation.

[0008] In one embodiment, a battery assembly is further included, which is electrically connected to the brushless motor. The housing assembly includes an outer shell and a mounting housing, with the mounting housing disposed within the outer shell. The mounting housing has a first mounting cavity, and the outer wall of the mounting housing and the inner wall of the outer shell enclose a second mounting cavity. The brushless motor and the counterweight are disposed in the first mounting cavity, and the battery assembly is located in the second mounting cavity. By adopting the above structure, the brushless motor and the counterweight are disposed within the outer shell via the mounting housing, and the mounting housing separates the battery assembly and other components from the brushless motor and the counterweight. This effectively prevents other components from becoming loose and affecting the operation of the brushless motor and the rotation of the counterweight. Furthermore, the second mounting cavity of the mounting housing surrounds the brushless motor, which helps to block the operating noise generated by the brushless motor during operation, further improving the quietness of the rocker.

[0009] In one embodiment, the stator has a first snap-fit ​​portion, and the mounting housing has a second snap-fit ​​portion. The second snap-fit ​​portion engages with the first snap-fit ​​portion to connect the stator and the mounting housing. By providing compatible first and second snap-fit ​​portions on the stator and mounting housing respectively, the snap-fit ​​engagement of the first and second snap-fit ​​portions facilitates the quick positioning and installation of the brushless motor.

[0010] In one embodiment, the stator has a first connecting hole, and the mounting housing has a second connecting hole. The first connecting hole and the second connecting hole are connected to the stator and the mounting housing by fasteners. By adopting the above structure, the first connecting hole and the second connecting hole can be tightly connected together by fasteners, thereby greatly improving the connection strength between the two.

[0011] In one embodiment, the mounting housing includes a housing body and a mounting cover. The mounting cover is detachably mounted on the housing body. The side of the mounting cover away from the housing body encloses the inner wall of the housing to form a second mounting cavity. The mounting cover and the housing body enclose a first mounting cavity. The stator is mounted on the mounting cover. By providing a detachably connected housing body and mounting cover, and fixing the stator on the mounting cover, it is convenient to place the brushless motor and counterweight in the second mounting cavity.

[0012] In one embodiment, the housing assembly further includes a positioning bracket disposed on the mounting housing and located within the second mounting cavity, with the battery assembly positioned on the positioning bracket. By employing this structure, the positioning bracket allows the battery assembly to be relatively fixed to the mounting housing, thereby ensuring that the battery assembly remains securely mounted during rocking motion and can be stably connected to the brushless motor.

[0013] In one embodiment, the positioning bracket includes an L-shaped bracket and a limiting part. One end of the L-shaped bracket is connected to the mounting housing, and the limiting part is located at the end of the L-shaped bracket away from the mounting housing. Both ends of the battery assembly are connected to the limiting part and the mounting housing, respectively. By utilizing the L-shaped bracket and the limiting part, a simple positioning bracket structure can be formed, facilitating the exposure of components such as the battery assembly. This provides convenience for the wiring connection between the brushless motor, the battery assembly, and the circuit board assembly.

[0014] In one embodiment, the limiting part is provided with a first limiting groove, and the top of the battery assembly is adapted to be inserted into the first limiting groove. The first limiting groove provides a limiting function for the installation of the battery assembly, and helps the battery assembly to remain securely installed when the rocker is swinging, and to be stably connected to the brushless motor.

[0015] In one embodiment, the outer wall of the mounting housing has a second limiting groove on the side facing the second mounting cavity, and the bottom of the battery assembly is adapted to be inserted into the second limiting groove. The second limiting groove provides a limiting function for the installation of the battery assembly, which helps improve installation efficiency and ensures that the battery assembly remains securely installed when the rocker is oscillating.

[0016] In one embodiment, the limiting portion is provided with a third engaging portion, and the mounting housing is formed with a fourth engaging portion. The third engaging portion and the fourth engaging portion engage with each other to connect the limiting portion and the mounting housing. By providing compatible third and fourth engaging portions on the limiting portion and the mounting housing respectively, the engagement of the third and fourth engaging portions facilitates the quick connection between the positioning bracket and the mounting housing.

[0017] In one embodiment, the L-shaped bracket and / or the limiting part is provided with a third connecting hole, and the outer shell is provided with a fourth connecting hole. The third connecting hole and the fourth connecting hole are connected to the L-shaped bracket and / or the limiting part and the outer shell by fastener engagement. By adopting the above structure, the mounting housing can be connected to the outer shell through the positioning bracket, and the third connecting hole and the fourth connecting hole can be tightly connected together by fastener engagement, thereby greatly improving the connection strength between the two.

[0018] In one embodiment, a lighting module is also included, which is disposed on the housing assembly. By incorporating the lighting module, the rocker can also function as a nightlight. Furthermore, the lighting module can have different lighting effects, thereby creating a better sleep environment for infants and young children to aid sleep and improve sleep quality. In addition, the lighting module can also provide lighting prompts, attracting user attention through red light settings or flashing lights to indicate the rocker's operating status to the user or the user.

[0019] In one embodiment, a sound module is also included, which is disposed on the housing assembly. The sound module may be configured to have a white noise mode and / or a sleep-aid music mode to create a better sleep environment for infants and young children, thereby assisting sleep and improving sleep quality.

[0020] In one embodiment, a connecting component is also included, which is disposed on the housing assembly and is used to connect the swing body.

[0021] The second aspect of this application provides a child's product.

[0022] A children's product includes: a fixed support; a rocking body movably mounted on the fixed support; and the aforementioned rocker connected to the rocking body.

[0023] The second aspect of this application provides a children's product that employs a rocker mechanism according to any of the above embodiments. The rocker mechanism contains a brushless motor that drives a counterweight to rotate. The center of gravity of the counterweight is offset from the rotation axis of the brushless motor's output end. Therefore, when the brushless motor starts and drives the counterweight to rotate around its output axis, it generates centrifugal force in a direction away from the rotation axis. This centrifugal force causes the rocker mechanism to rock the main body. This device has a simple structure, effectively reducing the size of the rocker mechanism and facilitating installation and use. Furthermore, using a brushless motor to drive the counterweight eliminates mechanical contact between the brushes and the commutator, reducing energy loss and friction noise, making it more suitable for applications such as baby products where noise control is crucial.

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0037] The rocker device of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0038] like Figures 1 to 4 As shown, this embodiment discloses a rocker, including: a housing assembly 1; a brushless motor 2 disposed in the housing assembly 1; and a counterweight 3 disposed on the output end of the brushless motor 2. The center of gravity of the counterweight 3 is offset from the rotation axis of the output end of the brushless motor 2, and the counterweight 3 is configured to rotate relative to the housing assembly 1 under the drive of the brushless motor 2.

[0039] This application provides a rocker with a brushless motor 2 inside its housing assembly 1 for driving a counterweight 3 to rotate. The center of gravity of the counterweight 3 is offset from the rotation axis of the output end of the brushless motor 2. When the brushless motor 2 starts and drives the counterweight 3 to rotate around its output axis, it generates centrifugal force in a direction away from the rotation axis. When the rocker is connected to the rocker body, this centrifugal force causes the rocker to rock the rocker body. This device has a simple structure, effectively reducing the size of the rocker and facilitating installation and use. Furthermore, the brushless motor 2, which drives the counterweight 3, can achieve a wide range of speed regulation by adjusting the input voltage, current, or magnetic field strength, and can operate stably from low to high speed. Compared with ordinary brushed motors, it eliminates the mechanical contact between the brushes and the commutator, reducing energy loss and friction noise, making it more suitable for applications with high noise control requirements, such as baby products.

[0040] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the brushless motor 2 includes a stator 21, a rotor 22, and a control module. The stator 21 is mounted on the housing assembly 1, and the rotor 22 is sleeved on the outside of the stator 21. The rotor 22 is connected to a counterweight 3, and the center of gravity of the counterweight 3 is offset from the rotation axis of the rotor 22. The control module is electrically connected to the stator 21, thereby driving the rotor 22 to rotate the counterweight 3 around the axis of the rotor 22. When the stator 21 is energized, the rotor 22 can drive the counterweight 3 to rotate around the rotation axis of the rotor 22 relative to the fixed stator 21 on its outside. By adopting the above-mentioned form of an outer rotor 22, on the one hand, it is easier to connect the counterweight 3 to the rotor 22; on the other hand, the outer rotor 22 has a large inertia, a robust structure, and a good load-bearing capacity, making it suitable for occasions with heavy loads such as when a counterweight 3 is installed.

By adopting the above structure, the brushless motor 2 and the counterweight 3 are disposed within the housing 11 via the mounting housing 12, and the mounting housing 12 separates the battery assembly 5 and other components from the brushless motor 2 and the counterweight 3, thereby effectively preventing the operation of the brushless motor 2 and the rotation of the counterweight 3 from being affected when other components become loose; furthermore, the mounting housing 12 having a second mounting cavity 102 surrounding the brushless motor 2 helps to block the operating noise generated by the brushless motor 2 during operation, further improving the quietness performance of the rocker.

The second snap-fit ​​portion 123 engages with the first snap-fit ​​portion 211 to connect the stator 21 and the mounting housing 12. By providing the first snap-fit ​​portion 211 and the second snap-fit ​​portion 123 respectively on the stator 21 and the mounting housing 12, the snap-fit ​​engagement of the first snap-fit ​​portion 211 and the second snap-fit ​​portion 123 facilitates the quick positioning and installation of the brushless motor 2.

The mounting cover 122 and the housing body 121 enclose to form a first mounting cavity 101. The stator 21 is mounted on the mounting cover 122. By providing a detachably connected housing body 121 and mounting cover 122, and by fixing the stator 21 on the mounting cover 122, it is convenient to mount the brushless motor 2 and the counterweight 3 in the second mounting cavity 102.
