Description

Technical Field

[0001] The invention relates to the field of vehicle accessories, in particular to a vehicle heat-insulating front cover and a vehicle. Background Art

[0002] In the layout of commercial vehicles, the vehicle's water tank and other cooling system components are usually installed at the front of the frame, and the front airflow assists in heat dissipation when the vehicle is driving. The front cover of a commercial vehicle is located at the front of the vehicle. In addition to being decorative and anti-collision, it also plays a role in ventilation and heat dissipation. For example, the center of the front cover of a commercial vehicle usually has a large area of ​​ventilation grille, and the vehicle's cooling system is located on the rear inner side of the front cover.

[0003] However, in commercial vehicles, the engine is usually installed naked on the frame and does not have a relatively closed engine compartment. In addition, due to the design requirements of ventilation and heat dissipation of the front cover of commercial vehicles, when the vehicle is in a cold environment and the engine is started in a cold state, the engine heats up slowly during driving, reducing fuel economy and the cab temperature is low, affecting the driving experience.

[0004] Therefore, in cold weather, it is common to see drivers covering the front hood area of ​​the vehicle with a quilt, plastic film or simple insulation cover to improve the insulation effect. However, this external insulation structure is usually weak and easily damaged by road debris during driving. On the other hand, third-party accessories have not been structurally verified, have poor compatibility with the vehicle, and are easy to fall off, especially flexible covering layers such as plastic films, which are easily rolled into the wheels after falling off, posing a major safety hazard. Summary of the invention

[0005] Aiming at the problems that a front cover heat preservation structure installed on a vehicle in a cold environment currently has potential safety hazards and poor aesthetics, the present invention provides a vehicle heat preservation front cover.

[0006] To solve the above problems, the technical solution adopted by the present invention is a vehicle heat-insulating front mask, including a front mask body, a heat-insulating component is provided on the side of the front mask body facing the interior of the vehicle, the heat-insulating component includes an airbag reel, a linear drive device is provided at at least one end of the airbag reel, the driving direction of the linear drive device is perpendicular to the airbag reel, an airbag is provided on the airbag reel, one side of the airbag is connected to the outer peripheral surface of the airbag reel, and the other side of the airbag is connected to the moving end of the linear drive device, and the front mask body is also provided with an inflation and deflation device connected to the airbag. The vehicle front mask provided by the present solution has an insulation component integrated therein. The insulation component adopts a retractable airbag structure. When insulation is needed, a linear drive device unfolds the airbag. After the airbag is inflated, it is filled on the rear side of the front mask body to achieve a windproof effect. The insulation component is located inside the vehicle and does not affect the appearance of the vehicle. It adopts an automatic deployment and recovery design and does not require disassembly and assembly by the driver and passengers. It can be directly fixed on the front mask, eliminating the problem of falling and greatly improving the safety of use. It is designed and manufactured in an integrated manner with the front mask to improve the matching degree with the front mask.

[0007] As a preferred implementation scheme of a vehicle heat preservation front cover, the airbag reel is provided with the linear drive device at both ends, and the two ends of the side of the airbag are respectively connected to the moving ends of the two linear drive devices. The airbag is pulled on both sides, the force is balanced, and the surface is more neat after unfolding.

[0008] As a preferred implementation scheme of a vehicle heat-insulating front cover, the linear drive device includes a synchronous belt assembly, the synchronous belt assembly includes a driving pulley and a driven pulley, a transmission belt is arranged around the driving pulley and the driven pulley, a connector is installed on the straight section of the transmission belt, the connector is connected to the airbag, and the driving pulley is connected to a driving motor. The linear drive device adopts a synchronous belt assembly, and the belt drive can be flexibly arranged, which is more suitable for the inner surface of the vehicle front cover that may be designed to be uneven, and can be flexibly installed.

[0009] As a preferred implementation of a vehicle heat-insulating front cover, the linear drive device further includes a housing, a synchronous belt assembly is arranged inside the housing, a notch is provided on one side of the housing, and one end of the connector extends out of the housing through the notch. The installation space of the synchronous belt assembly is relatively independent to avoid interference with other components of the vehicle frame.

[0010] As a preferred implementation of the vehicle heat-insulating front cover, a roller is installed at one end of the connecting member located in the shell, and the outer periphery of the roller is in rolling contact with the inner side surface of the shell, thereby improving the stability of the connecting member.

[0011] As a preferred implementation scheme of the vehicle heat-insulating front cover, the airbag reel is coaxially connected with the driving pulley or the driven pulley. The airbag reel moves synchronously with the synchronous belt assembly to achieve synchronous pulling and retracting of the airbag.

[0012] As a preferred implementation scheme of a vehicle thermal insulation front mask, the airbag reel is horizontally arranged at the upper or lower part of the side of the front mask body, and the linear drive device is vertically arranged at both sides of the side of the front mask body.

[0013] As a preferred implementation scheme of a vehicle heat-insulating front mask, the area and shape of the airbag are matched with the area and shape of the front mask body, thereby increasing the coverage area and thus improving the heat-insulating effect.

[0014] As a preferred implementation of a vehicle heat-insulating front cover, the connector is connected to the airbag via an elastic cord, which can compensate for a slight change in the linear speed of the airbag during the retraction process due to the thickness of the airbag on the reel, thereby making the deployed airbag more tightly tensioned and allowing the airbag to be more tightly retracted on the reel.

[0015] On the other hand, the present invention also provides a vehicle, which adopts the above-mentioned vehicle heat-insulating front cover. The vehicle adopts the above-mentioned heat-insulating front cover, which has a better heat-insulating effect, saves the driver and passengers from manually installing the heat-insulating structure, and the heat-insulating component of the vehicle is installed more firmly, which greatly improves the safety of the vehicle; at the same time, the appearance of the vehicle is not changed, and it is more beautiful.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are that the vehicle insulation front cover provided by the present invention is an innovative solution designed for commercial vehicles under cold start conditions, and its multiple advantages and use effects are fully reflected in the following aspects: First, the insulation front cover significantly improves the insulation performance of the vehicle through the built-in insulation component, especially the deployable airbag structure. In the cold winter or at night, when the vehicle is parked, this design can effectively maintain the temperature of the engine and its surrounding components, thereby reducing the damage to the engine during cold start. Cold start is a major challenge facing commercial vehicles, because low temperature will increase the viscosity of the engine oil and reduce the lubrication performance, and the design of the present invention helps to alleviate this problem. Secondly, the automatic deployment and recovery function of the insulation front cover greatly improves the safety of use. When it is needed, the airbag can be automatically inflated and deployed, covering the front part of the engine compartment to form an effective insulation layer. When it is not needed, the airbag can be automatically recovered without the need for the driver and passengers to perform complex manual operations, which not only reduces the operation steps, but also avoids the risk of injury caused by improper operation. In addition, the design of the insulation component fully considers the aesthetics and matching of the vehicle. Since the insulation component is located inside the vehicle, it will not affect the appearance design of the vehicle, and it is designed and manufactured in an integrated manner with the front mask, making the vehicle more integrated and more coordinated in appearance. At the same time, the linear drive device of the synchronous belt assembly of the present invention has excellent stability and adaptability, can adapt to the complex structure of the inner surface of the front mask of different models, and the installation space is independent, which reduces the interference with other vehicle components and improves the flexibility and reliability of installation. Furthermore, the area and shape of the airbag are carefully designed to ensure perfect fit with the front mask, maximize the coverage area, and improve the insulation effect. The design of the elastic rope connector ensures the tension state of the airbag after deployment, ensuring the durability of the insulation effect. Finally, the commercial vehicle using the insulation front mask of the present invention not only has a better insulation effect under cold start conditions, the installation is more firm and reliable, and it does not affect the original appearance of the vehicle, and improves the overall safety and aesthetics of the vehicle. This innovative design undoubtedly enhances the market competitiveness of the vehicle, provides a more comfortable and safe use experience for drivers and passengers, and also provides convenience for vehicle maintenance and maintenance.

DETAILED DESCRIPTION

[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] Embodiment 1 The vehicle heat preservation front cover of the present invention is designed to improve the heat preservation performance of the vehicle while ensuring a compact structure and perfect functions. Figure 1-3 As shown, the front mask is mainly composed of a front mask body 1, and a heat preservation component is arranged on one side of the interior thereof (the side facing the vehicle frame). The heat preservation component mainly includes an airbag reel 3, at least one end of which is equipped with a linear drive device 4, the driving direction of which forms a vertical angle with the axis of the airbag reel 3, and an airbag 2 is arranged on the airbag reel 3, one side of the airbag 2 is connected to the outer peripheral surface of the airbag reel 3, and the other side is connected to the moving end of the linear drive device 4. In this way, when the linear drive device 4 is working, it can drive the airbag 2 to unfold. An inflation and deflation device 5 is also arranged on the inner side of the front mask body 1, which is connected to the airbag 2 and is used to control the inflation and deflation of the airbag to achieve a heat preservation effect.

[0024] In order to enhance the driving ability of the airbag reel 3, it is preferred to provide linear drive devices 4 on both sides of the airbag reel, and the two side edges of the airbag 2 are respectively connected to the moving ends of the two linear drive devices 4, ensuring the synchronization and stability of the airbag deployment and winding.

[0025] The linear drive device 4 is composed of a synchronous belt assembly, including a driving pulley 41 and a driven pulley 42. A transmission belt 43 is installed around the driving pulley 41 and the driven pulley 42, and the transmission belt 43 is tightened. A connector 44 is installed on the straight section of the transmission belt 43, and the connector 44 is connected to the airbag 2. The driving pulley 41 is powered by a drive motor 6, which is also installed on the inner side of the front mask body. In order to ensure the reliability and durability of the linear drive device 4, the design also includes a shell 45. The synchronous belt assembly is located inside the shell 45, and a relatively independent operating space is set to prevent other vehicle structures (such as wiring harnesses, etc.) from entering the operating space of the belt drive under the influence of vehicle vibration and causing interference. A notch is provided on one side of the shell 45, so that one end of the connector 44 can pass through the notch and extend to the outside of the shell 45, thereby connecting to the airbag 2. Inside the shell 45, a roller 46 is installed at one end of the connecting member 44, and the outer periphery of the roller 46 maintains rolling contact with the inner surface of the shell 45, thereby reducing friction. At the same time, the contact between the roller 46 and the shell 45 balances the reaction force of the airbag 2 on the connecting member 44, thereby reducing the torsional effect of the reaction force on the transmission belt, making the belt drive assembly run more smoothly and stably, and improving the smoothness of the movement.

[0026] In terms of structural layout, the airbag reel 3 is coaxially connected with the driving pulley 41 or the driven pulley 42. This design simplifies the transmission system and improves the transmission efficiency. The airbag reel 3 is horizontally arranged on the upper or lower side of the front mask body 1, and the linear drive device is vertically arranged on both sides of the front mask body 1. This layout saves space and is convenient for installation and maintenance. The area and shape of the airbag 2 are carefully designed to match the area and shape of the front mask body 1, ensuring the maximum insulation effect.

[0027] When this solution is in operation, the drive motor and the inflation and deflation device can be connected to the vehicle's central control system. When the driver and passengers need to keep the vehicle warm, the drive motor is started, the belt drive assembly and the airbag reel rotate synchronously, the airbag is pulled out to cover the inside of the front cover, and then the inflation and deflation device inflates the airbag, which swells and fills between the front cover, the water tank and other vehicle components to achieve the insulation function.

[0028] Furthermore, due to the thickness of the airbag wound on the airbag reel, during the airbag deployment process, the release linear speed of the airbag changes slightly, while the connector in the belt drive assembly maintains a constant speed, so that there is a speed difference between the upper and lower ends of the airbag. The airbag is relatively loose after being fully released. In order to adapt to the speed difference, the connector 44 is connected to the airbag 2 by an elastic rope, which can tension the airbag when the airbag release speed is accelerated. In addition, after the airbag is inflated, the dimensions of its upper and lower ends will shrink and generate a pullback force. At this time, the elastic rope is stretched to prevent the pullback force from directly acting on the belt drive assembly. In this way, the flexibility of the airbag 2 in motion is guaranteed, and its stability in different states is ensured.

[0029] It should also be noted that the elastic rope is only a preferred embodiment and is not a necessary setting. In other embodiments, if the elastic rope is not provided, the airbag itself becomes a nearly rigid structure with a basically fixed shape after inflation, and can maintain a stable shape without additional tension. At the same time, the transmission belt also has a certain elasticity, which can compensate for the length contraction after inflation.

[0030] Embodiment 2 This embodiment further provides a vehicle, which adopts the vehicle thermal insulation front cover provided by the first embodiment.

[0031] It can be seen from the above embodiments that the beneficial effect of the present invention is that the vehicle insulation front cover provided by the present invention is an innovative solution designed for commercial vehicles under cold start conditions, and its multiple advantages and use effects are fully reflected in the following aspects: First, the insulation front cover significantly improves the insulation performance of the vehicle through the built-in insulation component, especially the deployable airbag structure. In the cold winter or at night, when the vehicle is parked, this design can effectively maintain the temperature of the engine and its surrounding components, thereby reducing the damage to the engine during cold start. Cold start is a major challenge facing commercial vehicles, because low temperature will increase the viscosity of the engine oil and reduce the lubrication performance, and the design of the present invention helps to alleviate this problem. Secondly, the automatic deployment and recovery function of the insulation front cover greatly improves the safety of use. When it is needed, the airbag can be automatically inflated and deployed, covering the front part of the engine compartment to form an effective insulation layer. When it is not needed, the airbag can be automatically recovered without the need for the driver and passengers to perform complex manual operations, which not only reduces the operation steps, but also avoids the risk of injury caused by improper operation. In addition, the design of the insulation component fully considers the aesthetics and matching of the vehicle. Since the insulation component is located inside the vehicle, it will not affect the appearance design of the vehicle, and it is designed and manufactured in an integrated manner with the front mask, making the vehicle more integrated and more coordinated in appearance. At the same time, the linear drive device of the synchronous belt assembly of the present invention has excellent stability and adaptability, can adapt to the complex structure of the inner surface of the front mask of different models, and the installation space is independent, which reduces the interference with other vehicle components and improves the flexibility and reliability of installation. Furthermore, the area and shape of the airbag are carefully designed to ensure perfect fit with the front mask, maximize the coverage area, and improve the insulation effect. The design of the elastic rope connector ensures the tension state of the airbag after deployment, ensuring the durability of the insulation effect. Finally, the commercial vehicle using the insulation front mask of the present invention not only has a better insulation effect under cold start conditions, the installation is more firm and reliable, and it does not affect the original appearance of the vehicle, and improves the overall safety and aesthetics of the vehicle. This innovative design undoubtedly enhances the market competitiveness of the vehicle, provides a more comfortable and safe use experience for drivers and passengers, and also provides convenience for vehicle maintenance and maintenance.
