Description

Technical Field

[0001] This utility model relates to the field of smart home, and in particular to an automatic charging base for a vacuum cleaner. Background Technology

[0002] With the improvement of people's living standards and the iterative upgrade of smart home technology, automatic vacuum cleaners have become the mainstream choice for modern home cleaning due to their convenience of being easy to operate without manual operation. These devices use rechargeable batteries as a power source, completely getting rid of the constraints of traditional power cords. They can autonomously plan cleaning paths through a built-in navigation system. However, the limited battery life has become a key factor restricting its continuous operation. As a result, an automatic charging base for vacuum cleaners has emerged.

[0003] The vacuum cleaner has a built-in power sensor that monitors the remaining battery power in real time. When the power is lower than a preset threshold, the vacuum cleaner will send a "charging request" signal to the charging base. After receiving the signal, the charging base will activate the positioning and guidance system, and at the same time, its own power module will enter the standby activation state to prepare to provide charging current. When the vacuum cleaner contacts the charging terminal of the base, the base will first send a low voltage detection signal to confirm that the connection is correct before starting the charging circuit to avoid charging failure caused by loose connection.

[0004] Currently, automatic charging docks for vacuum cleaners are driving the industry's intelligent development, but there are technical pain points regarding docking stability. When the vacuum cleaner returns to its charging dock, factors such as uneven ground, navigation errors, or docking angles can cause the charging contacts to become loose or disconnected, resulting in charging interruption. When infrared guidance is affected by surrounding obstacles, the vacuum cleaner's docking position may shift, leading to poor contact. Therefore, an automatic charging dock for vacuum cleaners is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic charging base for vacuum cleaners, which aims to improve the problem of charging interruption caused by loose or disconnected charging contacts in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic charging base for a vacuum cleaner includes a housing. Two support columns are fixedly connected to the outer wall of the housing. Limiting columns are slidably connected to the inner walls of the two support columns. A protrusion is fixedly connected to the outer wall of each limiting column. A retaining ball is fixedly connected to one side of each limiting column. A spring is sleeved on the outer wall of each limiting column. A charging interface is slidably connected to the inner wall of the housing. A positioning component is fixedly connected to the outer wall of the charging interface. Two slots are formed on the outer wall of the charging interface. An external power supply is fixedly connected to the positioning outer wall of the housing.

[0008] As a further description of the above technical solution:

[0009] The positioning component includes two guide blocks, with one side of each guide block being fixedly connected to the outer wall of the charging interface. The inner wall of the housing has two guide grooves, and a spring pad is fixedly connected to the inner wall of the housing.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the protrusion is slidably connected to the inner wall of the housing, and the outer wall of the ball is slidably connected to the outer wall of the housing;

[0012] As a further description of the above technical solution:

[0013] The outer wall of the ball engages with the inner wall of the slot, and the outer wall of the ball contacts one side of the protrusion.

[0014] As a further description of the above technical solution:

[0015] One side of the spring is fixedly connected to the inner wall of the housing, and the other side of the spring is fixedly connected to one side of the protrusion.

[0016] As a further description of the above technical solution:

[0017] The top of the spring pad is in contact with the bottom of the charging interface, and the outer wall of the retaining ball is slidably connected to the outer wall of the charging interface;

[0018] As a further description of the above technical solution:

[0019] The protrusion has a circular cross-sectional shape, and the guide groove has a rectangular cross-sectional shape.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the outer wall of the charging interface slides along the inner wall of the housing under the guidance of the guide block, it will squeeze the retaining ball and drive the limiting post to move, so that the protrusion compresses the spring to store elastic potential energy. When the charging interface slides to the predetermined position, the retaining ball and the slot are aligned, and the elastic potential energy of the spring is released instantly, pushing the protrusion to drive the limiting post to reset, so that the retaining ball is locked into the slot. This design achieves a tight fixation between the charging interface and the housing through the cooperation of the spring and the retaining ball and slot, reducing the probability of charging interruption caused by poor connection or loosening of the charging contacts, and improving the operating efficiency of the charging base.

[0022] 2. In this utility model, when the charging interface is about to enter the housing for charging, the cooperation between the guide block and the guide groove can accurately guide it to cut into the predetermined position, avoiding docking misalignment. At the same time, the elastic buffer design of the spring pad will be compressed and deformed when the charging interface contacts the housing, absorbing the collision energy between the two. This structure not only ensures that the charging interface is positioned with high precision, but also reduces component wear through the spring pad, so that the housing maintains structural integrity during long-term use. Compared with traditional designs, it can extend the service life of the device and improve the durability of the charging base. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 3This utility model provides an embodiment of an automatic charging base for a vacuum cleaner, comprising a housing 1, which serves as the main structure of the charging base and enables docking and charging with a vacuum cleaner. Two support columns 2 are fixedly connected to the outer wall of the housing 1, and limit columns 3 are slidably connected to the inner walls of the two support columns 2. The limit columns 3 can move within the support columns 2. A protrusion 4 is fixedly connected to the outer wall of the limit column 3, and the protrusion 4 moves with the movement of the limit column 3. A retaining ball 5 is fixedly connected to one side of the limit column 3, and the retaining ball 5 is a key component for fixing. A spring 6 is sleeved on the outer wall of the limit column 3, and the spring 6 stores and releases energy through elastic deformation. A charging interface 9 is slidably connected to the inner wall of the housing 1. The charging interface 9 is used for docking and charging with a vacuum cleaner and can slide within the housing 1 to achieve precise positioning and connection during charging. A positioning component is fixedly connected to the outer wall of the charging interface 9.

[0031] The positioning component ensures that the charging interface 9 slides accurately within the housing 1 and smoothly reaches the charging position. Two slots 10 are provided on the outer wall of the charging interface 9. The slots 10 cooperate with the ball 5 to provide a fixed position for the charging interface 9 and ensure a stable charging connection. An external power supply 12 is fixedly connected to the outer wall of the housing 1. The external power supply 12 provides power input to the charging base and is the energy source for the charging function. The positioning component includes two guide blocks 8, which are fixed to the outer wall of the charging interface 9. Two guide grooves 7 are provided on the inner wall of the housing 1. The guide grooves 7 provide a sliding track for the guide blocks 8 to ensure that the moving path of the charging interface 9 is accurate and avoids deviation. A spring pad 11 is fixedly connected to the inner wall of the housing 1. The spring pad 11 provides cushioning when the charging interface 9 slides into the housing 1 to reduce impact and protect the charging interface 9 and the housing 1.

[0032] Reference Figures 2 to 4The outer wall of protrusion 4 is slidably connected to the inner wall of housing 1, ensuring stable movement of protrusion 4 and driving the limiting post 3 to move synchronously. The outer wall of the retaining ball 5 is slidably connected to the outer wall of housing 1, allowing the retaining ball 5 to slide inside and outside housing 1, realizing engagement and disengagement with the retaining groove 10. The outer wall of retaining ball 5 and the inner wall of retaining groove 10 engage. When charging interface 9 reaches the predetermined position, retaining ball 5 is embedded in retaining groove 10, achieving a firm fixation between the two. The outer wall of retaining ball 5 contacts one side of protrusion 4, ensuring that the movement of protrusion 4 can drive retaining ball 5 to move synchronously. One side of spring 6 is fixedly connected to the inner wall of housing 1, and the other side is fixedly connected to one side of protrusion 4, so that the spring 6 can move synchronously. Spring 6 can effectively apply elastic force to protrusion 4, driving ball 5 to engage or disengage. The top of spring pad 11 contacts the bottom of charging interface 9. When charging interface 9 slides into housing 1, spring pad 11 is compressed and buffered to reduce collision damage. The outer wall of ball 5 is slidably connected to the outer wall of charging interface 9. When charging interface 9 slides, ball 5 is squeezed and moves along its outer wall, triggering the elastic action of spring 6. The cross-sectional shape of protrusion 4 is annular, which provides stronger stability and reduces shaking when sliding with the inner wall of housing 1. The cross-sectional shape of guide groove 7 is rectangular, matching the shape of guide block 8 to ensure accurate guidance and smooth movement of charging interface 9.

[0033] Working principle: When the charging interface 9 is about to enter the housing 1 for charging, thanks to the cooperation of the guide block 8 and the guide groove 7, the guide block 8 slides precisely on the inner wall of the guide groove 7 to guide the charging interface 9 into the predetermined position inside the housing 1 for charging. Thanks to the presence of the spring pad 11, most of the impact force between the charging interface 9 and the housing 1 can be buffered when the charging interface 9 enters the housing 1, which greatly extends the service life of the housing 1. When the outer wall of the charging interface 9 slides on the inner wall of the housing 1 under the guidance of the guide block 8, the retaining ball 5 is squeezed by the charging interface 9, causing the retaining ball 5 to drive the limiting post 3 into the housing 1. The charging interface 9 moves, causing the protrusion 4 to compress the spring 6, resulting in elastic deformation and storage of elastic potential energy. At the same time, the charging interface 9 continues to move until it reaches the predetermined position. At this point, the retaining ball 5 contacts the retaining groove 10, causing the height difference of the retaining ball 5 to disappear. This causes the elastic potential energy of the spring 6 to burst instantly, which in turn causes the spring 6 to push the protrusion 4 to move along with the limiting post 3. This makes the retaining ball 5 firmly engaged with the retaining groove 10, achieving the effect of firmly fixing the charging interface 9 and the housing 1. This greatly reduces the probability of charging interruption caused by loose or disconnected charging contacts, thereby significantly improving the operating efficiency of the housing 1.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
