Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle drainage trough structure technology, and in particular to a frost-resistant drainage trough structure. Background Technology
[0002] Car drainage channels are distributed in several key parts of the vehicle body. Their main function is to guide rainwater out of the vehicle and prevent water from entering the internal structure. They generally include windshield drainage channels, door drainage channels, rear pillar drainage channels, sunroof drainage holes, engine compartment drainage holes, and trunk drainage holes.
[0003] Existing windshield drain channels are generally located below the windshield and are made of plastic guide channels. They are responsible for draining rainwater from the glass and directing the water to the underside of the vehicle through drainage pipes. In cold, rainy or snowy weather, or when the drainage holes are blocked by fallen leaves or other foreign objects, water can easily accumulate in the channels. Furthermore, due to weather conditions, the accumulated water is prone to freezing. As the volume increases during the freezing process, the drain channels are compressed and are prone to freezing and cracking, which affects their service life.
[0004] Therefore, an antifreeze and crack-resistant drainage trough structure is provided to solve the above problems. Utility Model Content
[0005] The main purpose of this invention is to solve the problems in the prior art, such as water accumulation in the drain when it is cold and snowy, or when the drain hole is blocked by foreign objects such as fallen leaves. Furthermore, due to the weather, the water is prone to freezing. As the volume increases during the freezing process, the drain is squeezed and is prone to freezing and cracking, which affects its service life.
[0006] This utility model provides a frost-resistant and crack-resistant drainage trough structure, the frost-resistant and crack-resistant drainage trough structure comprising:
[0007] The main body of the drainage trough has a drain hole at its bottom and a first filter mechanism at the upper outlet of the drain hole. An energy storage mechanism is installed on the inner wall of the higher side of the main body of the drainage trough. The interior of the main body of the drainage trough has a power supply structure and a heating structure. The main body of the drainage trough includes a rigid outer shell and a deformable and recoverable inner shell, forming a cavity between the rigid outer shell and the deformable and recoverable inner shell. End caps are provided on both sides of the main body of the drainage trough to cover the cavity.
[0008] Furthermore, the rigid outer shell is a plastic rigid shell, and multiple snap-fit buckles are provided on the outer surface of the plastic rigid shell for snapping with the external vehicle body structure.
[0009] Furthermore, the deformable inner shell is a rubber inner shell, and the rubber inner shell and the plastic hard shell are fixedly connected to form a cavity, and the power supply structure and the heating structure are both disposed in the cavity.
[0010] Furthermore, the energy storage mechanism is a miniature solar panel, and the miniature solar panel is electrically connected to the power supply structure.
[0011] Furthermore, the power supply structure includes a button cell battery, a power management module, a power switch, and a heating structure. The button cell battery and the micro solar panel are simultaneously electrically connected to the power management module, the power management module is electrically connected to the power switch, and the power switch is electrically connected to the heating structure.
[0012] Furthermore, the heating structure is a heating resistance wire, which is disposed inside the cavity and surrounds the side wall of the drain hole.
[0013] Furthermore, the first filtration mechanism is a first filter screen.
[0014] Furthermore, the end cap and the cavity are interference-fitted.
[0015] This utility model utilizes a double-layered water trough design. The inner water trough is made of rubber, so even if the water turns into ice, it will not affect the outer hard shell, thus improving the service life. At the same time, a micro solar panel can be installed to store electrical energy and slightly affect the temperature inside the trough, so as to prevent it from freezing or speed up the melting process.

[0019] This utility model provides a frost-resistant drainage trough structure, comprising: a drainage trough body, a drain hole at the bottom of the drainage trough body, a first filter mechanism at the upper outlet of the drain hole, a power storage mechanism on the inner wall of the higher side of the drainage trough body, a power supply structure and a heating structure inside the drainage trough body, the drainage trough body including a rigid outer shell and a deformable and recoverable inner shell, forming a cavity between the rigid outer shell and the deformable and recoverable inner shell, and end caps on both sides of the drainage trough body for covering the cavity; the main purpose of this utility model is to solve the problems in the prior art, such as water accumulation in the trough during cold rainy or snowy weather, or when the drain hole is blocked by foreign objects such as fallen leaves, and the water easily freezing due to weather conditions. During the freezing process, the volume increases, causing the drainage trough to be compressed, which can easily lead to freezing and cracking, affecting its service life.
[0020] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0021] Example
[0022] Reference manual attached Figure 1-3 This embodiment provides an anti-freeze and crack-resistant drainage trough structure, which includes:
[0023] The main body of the drain trough 1 has a drain hole at the bottom and a first filter mechanism 6 at the upper outlet of the drain hole 3. The main body of the drain trough includes a rigid outer shell and a deformable and recoverable inner shell, and a cavity is formed between the rigid outer shell and the deformable and recoverable inner shell. End caps 4 are provided on both sides of the main body of the drain trough to cover the cavity. The end caps and the cavity are interference fit.
[0024] The rigid outer shell is made of plastic, and multiple snap-fit buckles are provided on the outer surface of the plastic rigid shell for engaging with the external vehicle body structure.
[0025] The deformable inner shell is a rubber inner shell, and the rubber inner shell and the plastic hard shell are fixedly connected to form a cavity.
[0026] The first filtration mechanism is the first filter screen.
[0027] During use, rainwater or snow flows out through the drainage holes inside the main body of the gutter. When the filter screen is blocked by leaves, causing water to accumulate in the gutter and freeze, the rubber inner shell can deform and compress the cavity space, avoiding direct compression of the hard outer shell of the gutter body, thus improving the service life of the gutter body. Since water increases in volume by about 10% when it turns into ice, the cavity does not need to be too large. The problem of the gutter freezing and cracking is solved by utilizing only a small portion of the space.
[0028] Example
[0029] Reference manual attached Figure 1-3 This embodiment provides an anti-freeze and crack-resistant drainage trough structure, which includes:
[0030] The main body of the drainage trough 1 has a drainage hole 3 at its bottom and a first filter mechanism at the upper outlet of the drainage hole. An energy storage mechanism is installed on the inner wall of the higher side of the drainage trough. The interior of the drainage trough has a power supply structure and a heating structure. The drainage trough includes a rigid outer shell and a deformable and recoverable inner shell, forming a cavity between them. End caps are provided on both sides of the drainage trough 1 to cover the cavity. The end caps 4 are interference-fitted with the cavity.
[0031] The rigid outer shell is made of plastic, and multiple snap-fit buckles are provided on the outer surface of the plastic rigid shell for engaging with the external vehicle body structure.
[0032] The deformable inner shell is made of rubber, and the rubber inner shell and the plastic hard shell are fixedly connected to form a cavity. The power supply structure and the heating structure are both set in the cavity.
[0033] The energy storage mechanism is a miniature solar panel 2, which is electrically connected to the power supply structure.
[0034] The power supply structure includes a coin cell battery (5), a power management module, a power switch, and a heating structure. Both the coin cell battery and the micro solar panel are electrically connected to the power management module, which is in turn electrically connected to the power switch. The power switch is also electrically connected to the heating structure. When sunlight is available and the micro solar panel generates electricity, it can continuously heat the cavity, affecting the temperature inside the tank and increasing the melting rate of the ice. It can also slow down the freezing process before ice forms. The power management module switches between the micro solar panel and the coin cell battery as the power source. The power switch can be controlled via Bluetooth or directly connected to the car's controller. The power switching method is similar to the power switching circuit of a calculator with both coin cell battery and solar power.
[0035] The heating structure is a heating resistance wire, which is set inside the cavity and surrounds the side wall of the drain hole.
[0036] The first filtration mechanism is the first filter screen 6.
[0037] During use, rainwater or snow flows out through the drainage holes inside the main body of the gutter. When the filter screen is blocked by leaves, causing water to accumulate in the gutter and freeze, the rubber inner shell can deform and compress the cavity space, avoiding direct compression of the hard outer shell of the gutter body, thus improving the service life of the gutter body. Since water increases in volume by about 10% when it turns into ice, the cavity does not need to be too large. The problem of the gutter freezing and cracking is solved by utilizing only a small portion of the space. Under conditions of light and when the micro solar panel generates electricity, it can continuously heat the cavity, affecting the temperature inside the gutter and increasing the melting rate of the ice. At the same time, it can also slow down the freezing rate before it freezes.
