Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and in particular to a dustproof ventilation mechanism, a carriage, and a vehicle. Background Technology

[0002] For vans, there are three main types of van box structures in the existing technology: van boxes without ventilation, van boxes with ventilation holes, and van boxes with mechanical ventilation valves. Each of these three types of van box structures has certain shortcomings.

[0003] Non-ventilated van-type cargo boxes are mostly used in small-capacity cargo boxes. In small-capacity cargo boxes, the amount of gas compressed at the moment of closing is small, resulting in less pressure and less impact deformation to the box body, as well as less closing resistance. This structure is not suitable for large-capacity cargo boxes. Without a ventilated structure, the closing pressure of a large-capacity cargo box can lead to deformation or excessive closing resistance, making it difficult to close.

[0004] Cargo boxes with vents are mostly used in large-capacity cargo boxes, and the vents are equipped with louvers or baffles. This type of structure offers relatively poor dust and water protection in actual use. Cargo boxes with mechanical vent valves are also commonly used in large-capacity cargo boxes, and the vent valve has a diaphragm valve body structure. This type of structure may be susceptible to problems such as foreign objects being inserted into the valve, causing valve failure. Summary of the Invention

[0005] In view of this, this application provides a dustproof ventilation mechanism, a carriage, and a vehicle, with the aim of solving the above-mentioned technical problems to a certain extent.

[0007] Based on the technical solutions described above, optionally, the closing process is characterized by the closing acceleration of the door component.

[0008] Based on any of the technical solutions described above, optionally, the upper side of the cover member is pivotally connected to the upper side of the ventilator housing, such that the lower side of the cover member can approach and move away from the lower side of the ventilator housing.

[0010] Based on any of the technical solutions described above, optionally, both the drive motor and the transmission structure are mounted on the vent cover.

[0011] Optionally, based on any of the technical solutions described above, the ventilation and dust prevention mechanism further includes a dustproof net, which is disposed within the airflow channel.

[0012] Optionally, based on any of the technical solutions described above, the cover member is further configured to close the airflow channel in response to the door member being in a closed state for a predetermined time.

[0013] Based on any of the technical solutions described above, optionally, the cover member has a recess facing the vent housing, the recess being able to cover the outer edge of the opening of the airflow channel to close the airflow channel.

[0015] According to a third aspect of this application, a van is provided, the van comprising the cargo box as described above.

[0016] Thus, according to the dustproof ventilation mechanism provided in this application, the cover component in the dustproof ventilation mechanism can determine the current ventilation demand of the car body by the action process performed by the door component of the car body, thereby opening the cover component during the closing process of the door component to prevent air pressure from impacting the door component during the closing process.

[0027] According to a first aspect of the embodiments of this application, a dustproof ventilation mechanism is provided, which will be described below in conjunction with... Figs. 1 to 3 Describe in detail the structure and working principle of the dustproof ventilation mechanism.

[0028] Prior to this application, all types of vans, regardless of their volume, faced the problem of air pressure impact when the doors were closed. However, for smaller vans, the air pressure inside was lower, so it did not have a significant impact on the van.

[0029] However, when the volume of the carriage increases, the air pressure often increases due to the increased gas volume. Therefore, when the volume of the carriage increases, ventilation is often carried out using ventilation holes with a certain shielding structure, such as the louvers or baffles mentioned in the background technology above. In short, the ventilation holes of this type of carriage are always open.

[0030] Normally open vents perform particularly poorly in harsh terrain, environments, and weather conditions, especially in terms of waterproofing and protection against foreign objects (such as sand and hail). Louvers or baffles are prone to displacement or even damage when subjected to impacts, which can lead to water and foreign objects entering the carriage and polluting the environment inside.

[0031] Furthermore, even without the threat of harsh terrain, harsh environment, and harsh weather, vehicles operating for extended periods are objectively in an environment with relatively high dust concentrations. The dust prevention effect of the constantly open vents is poor, and dust can easily enter the cabin, polluting the cabin environment. At the same time, it can also accumulate at the vents, clogging them.

[0032] An improvement to the normally open vent is the mechanical vent valve, which is essentially a diaphragm valve body structure that allows for both ventilation and the blocking of water, dust and other blocky foreign objects.

[0033] However, this type of mechanical ventilation valve still has significant drawbacks. On the one hand, although the diaphragm can allow air to pass through, its ventilation capacity is limited due to the need to block water, dust, and other large foreign objects. Even when the carriage doors are closed, the air pressure still exerts a certain impact on the carriage. On the other hand, the diaphragm itself is a passive and non-adjustable structure. Not only is it exposed to the environment inside and outside the carriage, making it susceptible to human damage, but it also cannot automatically open and close to adapt to the opening and closing of the carriage doors. This is a crucial connection between the closed state of the carriage doors and ventilation requirements, a point largely overlooked in existing technologies.

[0034] Based on the above-mentioned shortcomings of the prior art, a ventilation and dust prevention mechanism according to the first aspect of the embodiments of this application is proposed to overcome the above problems.

[0035] According to the dustproof ventilation mechanism provided in the embodiments of this application, the dustproof ventilation mechanism is applied to the compartment of a van, and the dustproof ventilation mechanism includes a ventilation cover 1 and a cover component 2.

[0036] In an embodiment, the ventilation cover 1 is used to be embedded in the carriage, and the ventilation cover 1 has an airflow channel 4, which is used to connect the internal environment of the carriage with the external environment in which the carriage is located.

[0037] In this embodiment, the cover member 2 is movably disposed relative to the ventilated cover 1, and the cover member 2 is capable of closing the airflow channel 4 and adjusting the opening degree of the airflow channel 4; In one embodiment, the carriage further includes a carriage body and a door component, the cover component 2 being configured to open in response to the door component performing a closing process.

[0038] Thus, according to the dustproof ventilation mechanism provided in the embodiments of this application, the cover member 2 in the dustproof ventilation mechanism can determine the current ventilation demand of the carriage according to the action process performed by the door member of the carriage, thereby opening the cover member 2 during the closing process of the door member to prevent air pressure from impacting the door member during the closing process.

[0039] According to the dustproof ventilation mechanism provided in the embodiments of this application, the closing process is characterized by the closing acceleration of the door component.

[0040] In one embodiment, the closing acceleration of the door component can be determined, for example, by installing an acceleration sensor on the door component. The direction of the acceleration sensor's movement (opening or closing, hereinafter the same) and the acceleration value are used to confirm whether the door component is in the closing process. Alternatively, in other examples, the direction of the acceleration sensor's movement can be disregarded; as long as the door component moves, the cover component 2 is opened. This allows the cover component 2 to open during the door component's opening process, opening the airflow channel 4 and causing the internal and external environments of the carriage to have the same pressure, reducing the difficulty of opening the door component.

[0041] In this embodiment, the door component can also be controlled to open and close via an electric strut controlled by the vehicle controller. In this case, an acceleration sensor can be placed on the output end of the electric strut, thereby confirming whether the door component is closing based on the direction of motion and acceleration value received by the vehicle controller from the acceleration sensor. Furthermore, examples of motion direction not relying on an acceleration sensor are as described above.

[0042] In this embodiment, the opening degree of the cover component 2 is determined based on the magnitude of the acceleration value from the accelerometer, i.e., a larger acceleration value corresponds to a larger opening degree, and a smaller acceleration value corresponds to a smaller opening degree.

[0043] According to the dustproof ventilation mechanism provided in the embodiments of this application, the upper side of the cover member 2 is pivotally connected to the upper side of the ventilation cover 1, so that the lower side of the cover member 2 can approach and move away from the lower side of the ventilation cover 1.

[0044] Thus, according to the dustproof ventilation mechanism provided in the embodiments of this application, the cover member 2 can naturally block the outer opening of the airflow channel 4, especially when it is open, it can guide foreign objects and water flow from the outside.

[0045] According to the dustproof ventilation mechanism provided in the embodiments of this application, the dustproof ventilation mechanism further includes a rotating shaft for pivotally connecting the ventilation cover 1 and the cover member 2. The rotating shaft is rotatably disposed on the ventilation cover 1. The dustproof ventilation mechanism further includes a drive motor and a transmission structure. The drive motor is connected to the rotating shaft via the transmission structure. The drive motor is used to drive the rotating shaft to rotate, so as to drive the cover member 2 to pivot relative to the ventilation cover 1.

[0046] As an example, the transmission structure can be a pair of meshing gears, with one gear mounted on the shaft of the drive motor and the other gear mounted on the pivot shaft 3. Furthermore, both ends of the pivot shaft 3 can be mounted to the vent housing 1 via bearings.

[0047] According to the dustproof ventilation mechanism provided in the embodiments of this application, the drive motor and the transmission structure are both mounted on the ventilation cover 1 to achieve integration. A housing can also be further provided on the outside of the drive motor and the transmission structure for protection.

[0048] According to the dustproof ventilation mechanism provided in the embodiments of this application, the ventilation and dustproof mechanism further includes a dustproof net, which is disposed in the airflow channel 4 to further play a role in dust prevention.

[0049] According to the dustproof ventilation mechanism provided in the embodiments of this application, the cover member 2 is further configured to close the airflow channel 4 after a predetermined time when the door member is in a closed state, so as to avoid the airflow channel 4 remaining open after the door is closed. At the same time, the predetermined time also helps to prevent the cover member 2 from closing the airflow channel 4 before the door member is fully closed.

[0050] According to the dustproof ventilation mechanism provided in the embodiments of this application, the cover member 2 has a recess facing the ventilation cover 1. The recess can cover the outer edge of the opening of the airflow channel 4 to close the airflow channel 4, thereby further improving the dustproof, waterproof and foreign object protection effect. A sealing ring can also be embedded in the opening of the airflow channel 4 to form a press seal when the cover member 2 abuts against the sealing ring.

[0051] according to Figs. 1 to 3 The working process of the dustproof ventilation mechanism will be described below.

[0052] When the cargo box (i.e., the truck bed) door is fully open, the dustproof ventilation mechanism is in the following state: Fig. 1 At this time, the dustproof ventilation mechanism is completely closed, and the ventilation volume is 0, which can effectively prevent dust and water.

[0053] like Fig. 2 As shown, when the cargo box door is closing, the electric strut of the door sends its stroke acceleration signal to the dustproof ventilation mechanism. The cover shaft of the dustproof ventilation mechanism rotates, and the cover of the dustproof ventilation mechanism opens. Because the cover of the dustproof ventilation mechanism opens outward, it can reduce the entry of rainwater on rainy days. The dustproof net inside the dustproof ventilation mechanism can effectively prevent foreign objects from entering the cargo box.

[0054] Five seconds after the cargo box is fully closed, the cover shaft of the dustproof ventilation mechanism rotates, closing the cover and effectively preventing dust and water damage. (See attached image.) Fig. 3 .

[0056] According to a third aspect of the embodiments of this application, a van is provided, which includes the above-mentioned cargo box and has the above-mentioned beneficial effects, which will not be repeated here.

[0057] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
