Description

Technical Field

[0001] This application relates to the technical field of control ball, and in particular to a control ball. Background Technology

[0002] Within the overall structure of the surveillance sphere, there is a significant gap between the housing and the mounting base. This seemingly small gap becomes a convenient channel for rainwater intrusion during rainy days. When raindrops fall from the sky, they impact the surveillance sphere at various angles and speeds under the influence of wind. Because of this gap between the housing and the mounting base, rainwater easily finds a secret passage and enters the surveillance sphere's interior.

[0003] Once rainwater enters the control sphere, a series of problems arise. The inside of the control sphere is a sophisticated electronic world where numerous components work together, and they have strict requirements for their operating environment. However, it is difficult for the rainwater to drain out. This is because the internal structure of the control sphere is not primarily designed for drainage; its space is limited and its layout is compact, lacking dedicated drainage channels for rainwater. Under the influence of gravity, rainwater may accumulate in low-lying areas or flow along circuit boards, wires, and other components, gradually seeping into every corner. Utility Model Content

[0004] The purpose of this application is to provide a control ball to solve the problem of water ingress between the housing and the mounting base.

[0005] The application provides a control ball with the following technical solution: it includes a mounting base, a housing rotatably connected to the mounting base, and a water-absorbing component disposed in the gap between the mounting base and the housing. When rainwater enters the control ball from the gap between the mounting base and the housing, the rainwater is first absorbed by the water-absorbing component to prevent the rainwater from further entering the control ball.

[0006] By adopting the above technical solution, when raindrops enter through the gap under the action of wind, the water-absorbing component, as the first line of defense, can quickly absorb the rainwater. Regardless of the angle and speed of the raindrops, once they enter the gap, there is a high probability that they will be intercepted by the water-absorbing component, thereby preventing rainwater from contacting the precision electronic components inside the control sphere. By preventing rainwater from penetrating further, the internal components with strict environmental requirements are protected, maintaining their normal working environment, reducing the possibility of short circuits, corrosion, and other malfunctions caused by rainwater, and ensuring the normal use and lifespan of the control sphere.

[0007] Optionally, the housing has a first cavity, the mounting base has a second cavity, the first cavity and the second cavity form a barrier cavity, and both the mounting base and the housing have drainage cavities that communicate with the barrier cavity.

[0008] By adopting the above technical solution, a barrier cavity is formed by the first cavity of the housing and the second cavity of the mounting base. Structurally, this barrier cavity is equivalent to setting up a protective line at a critical part of the control ball (near the connection between the mounting base and the housing). When rainwater attempts to enter the control ball from the outside through the gap between the mounting base and the housing, the barrier cavity can temporarily contain and block the rainwater, preventing it from directly contacting the more delicate electronic components inside the control ball, thus providing initial waterproofing. By cleverly utilizing the structure of the mounting base and the housing itself to set up the barrier cavity and drainage cavity, the limited internal space of the control ball is not excessively occupied. Waterproofing and drainage functions are achieved without affecting the overall compact layout and normal function of the control ball, demonstrating the rationality and efficiency of the structural design.

[0009] Optionally, the drainage cavity is provided with a guide surface.

[0010] By employing the above technical solution, the guiding surface provides specific directional guidance for the flow of rainwater within the drainage chamber. When rainwater enters the drainage chamber, its flow direction may be uncertain due to factors such as uneven surface tension and gravity distribution. The guiding surface overcomes these problems, directing rainwater towards the drain outlet in the designed direction, thereby accelerating the discharge speed and preventing rainwater accumulation within the drainage chamber. The guiding surface also optimizes the drainage path, allowing rainwater to flow more smoothly within the drainage chamber. Especially when the drainage chamber structure is complex or space is limited, the guiding surface ensures that rainwater is discharged along the most advantageous path, reducing the possibility of rainwater meandering or stagnating within the chamber and improving the efficiency of the entire drainage system.

[0011] Optionally, the barrier cavity is provided with a squeezing mechanism for the water-absorbing component, and the output end of the squeezing mechanism abuts against the water-absorbing component;

[0012] The extrusion mechanism includes an extrusion roller, a power source that drives the extrusion roller to press around the water absorption assembly, and connecting parts that connect the extrusion roller and the extrusion roller respectively. The extrusion roller extrudes the water absorption assembly under the combined action of the inner wall of the drainage chamber.

[0013] By adopting the above technical solution, if the water-absorbing component remains saturated for a prolonged period after absorbing rainwater, its water absorption capacity will decrease, potentially even becoming a new water source hazard. The squeezing mechanism within the barrier cavity squeezes the water-absorbing component, expelling the absorbed water and ensuring it maintains good absorption performance, thus better preventing rainwater from entering the control ball. The squeezing rollers, acting in conjunction with the inner wall of the drainage cavity, further compress the water-absorbing component; this design cleverly utilizes the existing structure of the drainage cavity. When the water-absorbing component is squeezed, the squeezed water can be directly discharged through the drainage cavity, achieving a close integration of water absorption and drainage functions and improving the efficiency of the entire waterproofing system.

[0014] Optionally, the connector includes a ring gear rotatably connected between the mounting base and the housing, a limiting part fixedly connected to the ring gear, and a mounting bracket fixedly connected to the ring gear. The power source drives the ring gear to rotate between the mounting base and the housing, and the mounting bracket drives the squeezing roller to squeeze the water-absorbing assembly.

[0015] By adopting the above technical solution, the limiting part is fixedly connected to the ring gear, which can limit and stabilize the movement of the ring gear, ensuring that it does not deviate or wobble during rotation and guaranteeing the accuracy of transmission. The power source drives the ring gear to rotate between the mounting base and the housing, realizing efficient power transmission from the power source to the ring gear. Due to the special ring structure of the ring gear, the power can be evenly distributed on its circumference, thus ensuring that the force in each direction is more balanced during subsequent motion conversion. In conjunction with other waterproof structures such as the drainage chamber, this extrusion mechanism further enhances the reliability of the waterproof system. Even under prolonged or heavy rainfall, the water-absorbing component can continue to function effectively, reducing the possibility of rainwater breaking through the defense line and entering the interior of the control ball due to saturation of the water-absorbing component, thereby better protecting the precision electronic components inside the control ball.

[0016] Optionally, the water-absorbing component abuts against the inner wall of the barrier cavity on three sides.

[0017] By adopting the above technical solution, the water squeezed out by the water-absorbing component under the action of the squeezing mechanism flows down the inner wall of the barrier cavity. The water flow guided by the inner wall provides a stable and predictable water flow path. Compared with disordered water flow diffusion, the water flowing down the inner wall is easier to control and manage, reducing the risk of water turbulence or splashing into other areas inside the control sphere, thus protecting other electronic components inside the control sphere from water flow. When a large amount of rainwater enters or the water-absorbing component is squeezed repeatedly, this stable water flow guidance mechanism can ensure a continuous supply of water to the drainage cavity. There will be no situation where excessive water accumulates in the barrier cavity due to poor water flow, affecting the performance of the water-absorbing component or causing damage to the inside of the control sphere, thus ensuring the waterproof and drainage performance of the control sphere under different rainfall intensities.

[0018] Optionally, the drainage cavity is provided with a drainage outlet communicating with the outside, and a one-way block is fixedly connected inside the drainage outlet, with gaps between the two ends of the one-way block and the two ends of the drainage outlet.

[0019] By adopting the above technical solution, the one-way block is fixedly connected inside the drain outlet, realizing the one-way drainage function. When the water pressure inside the drain chamber is higher than that of the external environment, water can be smoothly discharged through the gap between the one-way block and the drain outlet. When external factors such as wind or splashing water may cause water or foreign objects to tend to flow back into the drain chamber, the one-way block will prevent this reverse flow, effectively preventing external water from re-entering the control ball and further enhancing the waterproof performance.

[0020] Optionally, the unidirectional block has inclined surfaces at both ends, so that the water flow channels at both ends of the unidirectional block gradually narrow from the inside to the outside.

[0021] By adopting the above technical solution, when external water attempts to enter the control ball through the drain outlet, the gradually narrowing channel causes the external water to encounter greater resistance as it approaches the inner end of the one-way block. Furthermore, the narrower outer channel makes it more difficult for external water to penetrate the one-way block and enter the interior. Compared to a channel of equal width, this design significantly enhances the one-way block's ability to block backflow, improving the reliability of waterproofing.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. From the water-absorbing component intercepting rainwater at the gap between the mounting base and the housing, to the barrier cavity containing and blocking rainwater, and then to the one-way block at the drain outlet preventing backflow of external water, multiple lines of defense are formed. Each line of defense effectively protects against rainwater entering the control sphere, greatly reducing the possibility of rainwater contacting the precision electronic components inside the control sphere, and effectively meeting waterproofing requirements under different conditions;

[0024] 2. The guiding surface and the inner wall of the drainage chamber guide the water flow, allowing rainwater to flow along a designed path inside the control sphere, avoiding detours and stagnation. This ensures that rainwater can be discharged quickly and smoothly from the drain outlet, improving the efficiency of the entire drainage system and effectively preventing internal water accumulation caused by poor drainage.

[0025] 3. The compression mechanism ensures that the absorbent component maintains good water absorption performance, avoiding failure due to component saturation. Even under prolonged or heavy rainfall, the absorbent component can operate stably, enhancing the reliability of the entire waterproofing system. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0031] This application discloses a control ball.

[0032] Example 1, referring to Figure 1 and Figure 2 A rainwater trap includes a mounting base 1, a housing 2 rotatably connected to the mounting base 1, and a water-absorbing component 3 disposed in the gap between the mounting base 1 and the housing 2. When rainwater enters the rainwater trap through the gap between the mounting base 1 and the housing 2, the rainwater is first absorbed by the water-absorbing component 3 to prevent further rainwater from entering the rainwater trap. A second cavity 52 is machined at the top of the mounting base 1, and a first cavity 51 is machined at the bottom of the housing 2. When the housing 2 and the mounting base 1 are assembled, the first cavity 51 and the second cavity 52 can form a barrier cavity 5. The water-absorbing component 3 is made of a highly absorbent material, such as a special absorbent sponge or absorbent fiber, and is shaped to match the gap between the mounting base 1 and the housing 2. This ensures that the water-absorbing component 3 can fit tightly against the inner wall of the barrier cavity 5 on three sides. During installation, it is accurately placed in the gap between the mounting base 1 and the housing 2 to effectively intercept rainwater entering through the gap.

[0033] refer to Figure 2 and Figure 3 Both the housing 2 and the mounting base 1 are provided with drainage chambers 4 that connect to the barrier cavity 5. The drainage chamber 4 is machined with an inclined guide surface 43 and has a drain outlet 41. Under the gravity of the rainwater, the guide surface 43 quickly flows to the drain outlet 41. A one-way block 42 is fixedly connected inside the drain outlet 41. The gap between the two ends of the one-way block 42 and the two ends of the drain outlet 41 ensures that water can pass smoothly during normal drainage, while effectively blocking the water flow when there is backflow pressure from the outside.

[0034] refer to Figure 2The barrier cavity 5 contains a squeezing mechanism 6 for the water-absorbing component 3. The output end of the squeezing mechanism 6 presses against the water-absorbing component 3. The squeezing mechanism 6 includes a squeezing roller 61, a power source 64 that drives the squeezing roller 61 to roll around the water-absorbing component 3, and connecting parts that connect the squeezing roller 61 to the squeezing roller 61. The squeezing roller 61 squeezes the water-absorbing component 3 under the combined action of the inner wall of the drainage cavity 4. A suitable small motor is selected as the power source 64. If the water-absorbing component 3 remains saturated for a long time after absorbing rainwater, its water absorption capacity will decrease, and it may even become a new water source hazard. The squeezing mechanism 6 in the barrier cavity 5 can squeeze the water-absorbing component 3, squeezing out the absorbed water, so that the water-absorbing component 3 can maintain good water absorption performance, thereby better preventing rainwater from entering the control ball. The squeezing roller 61 squeezes the water-absorbing component 3 under the combined action of the inner wall of the drainage cavity 4. This design cleverly utilizes the existing structure of the drainage cavity 4. When the water-absorbing component 3 is squeezed, the squeezed water can be directly discharged through the drainage chamber 4, realizing a close combination of water absorption and drainage functions and improving the efficiency of the entire waterproof system.

[0035] refer to Figure 2 The ring gear 63 is rotatably connected between the mounting base 1 and the housing 2, the limiting part 65 is fixedly connected to the ring gear 63, and the mounting bracket 62 is fixedly connected to the ring gear 63. The power source 64 drives the ring gear 63 to rotate between the mounting base 1 and the housing 2, and drives the squeezing roller 61 to squeeze the water absorption assembly 3 through the mounting bracket 62. The limiting part 65 can be a block structure or other form that protrudes from the surface of the ring gear 63. Its function is to limit the axial and radial displacement of the ring gear 63 during rotation and ensure the relative position stability of the ring gear 63 and other components.

[0036] The implementation principle of the control ball according to this application embodiment is as follows: both the housing 2 and the mounting base 1 are provided with a drainage cavity 4 that connects to the barrier cavity 5, and an inclined guide surface 43 is machined inside the drainage cavity 4. When rainwater enters the drainage cavity 4, under the action of gravity, the guide surface 43 provides a specific flow direction for the rainwater. According to the principles of fluid mechanics, the rainwater can flow quickly and smoothly along the guide surface 43 to the drain outlet 41.

[0037] The squeezing mechanism 6 installed inside the barrier cavity 5 is used to squeeze and drain the water-absorbing component 3. After absorbing a certain amount of rainwater, the water-absorbing component 3 will become saturated, and its water absorption capacity will decrease. At this time, it is necessary to discharge the absorbed water. The power source 64 in the squeezing mechanism 6 drives the relevant components to work, and drives the squeezing roller 61 to roll and press the water-absorbing component 3 through the connecting parts.

[0038] The power source 64 of the extrusion mechanism 6 transmits power by driving the ring gear 63 to rotate between the mounting base 1 and the housing 2. The special ring structure of the ring gear 63 allows the power to be evenly distributed on its circumference, thus ensuring a more balanced force in all directions during rotation.

[0039] The limiting part 65 fixedly connected to the ring gear 63 restricts the axial and radial displacement of the ring gear 63 during rotation. In the axial direction, the limiting part 65 cooperates with the corresponding structures on the mounting base 1 and the housing 2 to prevent the ring gear 63 from moving up and down during operation; in the radial direction, the limiting part 65 ensures the relative position stability of the ring gear 63 with other components, avoiding collisions or deviations from the normal movement trajectory caused by external interference or vibrations during movement.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
