Problems solved by technology

[0003] In China's automobile trend, SUV models are the most representative models. Compared with sedan models, SUV models use more parts, so the probability of abnormal noise is higher. Among them, the abnormal noise of the trunk curtain of SUV models is the most It is typical, especially when the model is driving on a bumpy road, the abnormal noise of the curtain is particularly prominent. At this stage, most OEMs mainly solve the problem of abnormal noise of the curtain by sticking felt. The solution can solve the above problems in the initial stage of the vehicle, but in the long run, due to the wear and tear of the felt, the abnormal noise will reappear repeatedly, causing complaints from customers, and cannot fundamentally solve the problem of abnormal noise of the curtain

Embodiment 1

[0024] Embodiment 1: as figure 2 and image 3 As shown, electromagnetic coil 1 is set on the inner cavity wall of the base opening, and when the covering curtain is in an open state, electromagnetic coil 2 is set on the position of the curtain body corresponding to electromagnetic coil 1, and electromagnetic coil 1 and electromagnetic coil 2 are energized interacting electromagnetic force.

[0025] The adjustable power supply, the first relay, and the electromagnetic coil are connected in series to form a power supply loop, and the adjustable power supply, the second relay, and the electromagnetic coil are connected in series to form a power supply loop. The output terminals of the main controller are respectively connected to the first relay and the second relay for controlling the on-off state of the first relay and the second relay.

[0026] The main controller controls the on-off state of the first relay and the second relay according to the obtained opening state of th...

Embodiment 2

[0031] Embodiment 2: as Figure 4As shown, the electromagnetic coils provided include three groups, the first electromagnetic coil, the second electromagnetic coil, and the third electromagnetic coil. The opening on the base divides the base into an upper base and a lower base. The third electromagnetic coil is arranged on the opening inner cavity wall of the lower base, and the second electromagnetic coil is arranged on the curtain body. The adjustable power supply is connected in series with the first relay and electromagnetic coil one to form a power supply circuit for electromagnetic coil one. Similarly, the adjustable power supply is connected in series with the second relay and electromagnetic coil two to form a power supply circuit for electromagnetic coil two; the adjustable power supply is connected in series with the third relay , The electromagnetic coil three forms a power supply circuit for the electromagnetic coil three. The output terminals of the main controll...

Embodiment 3

[0034] Embodiment 3: as Figure 5 , 6 As shown, for the further improvement of Embodiments 1 and 2, it includes four sets of electromagnetic coils and four relays. The adjustable power supply is connected to the first electromagnetic coil through the first relay, and the adjustable power supply is connected to the second electromagnetic coil through the second relay. The adjustable power supply is connected to the electromagnetic coil three through the third relay, and the adjustable power supply is connected to the electromagnetic coil four through the fourth relay; the main controller controls the on-off of the four relays according to the open state of the curtain collected by the state acquisition module. Electromagnetic coil one is set on the upper base, and can be set on the outer shell or inner cavity wall of the upper base; electromagnetic coil three is set on the outer shell or inner cavity wall of the lower base; electromagnetic coil two is set on the upper surface o...

Abstract

The invention discloses an object sheltering curtain used for a vehicle. The object sheltering curtain comprises a base and a curtain body. An opening is formed in the base. One end of the curtain body is connected with a rotary shaft in a cavity of the base through the opening. The base is provided with a first electromagnetic coil assembly. The curtain body is provided with a second electromagnetic coil assembly. A magnetic field generated when the second electromagnetic coil assembly is powered on and a magnetic field generated by the first electromagnetic coil assembly generate mutual acting forces. The object sheltering curtain has the advantages that magnetic field forces acting with each other are generated through the electromagnetic coil assemblies so that the portion, overlappedwith the position of the opening, of the curtain body can be tightly pressed or the portion, in the position of the opening, of the curtain body can be suspended due to force mutual repulsion, the curtain body cannot collide with the base due to the force effect in the vehicle vibration process, so that produced abnormal sound is reduced, and noise in the vehicle traveling process is reduced.

Description

technical field [0001] The invention relates to an automobile shade, in particular to a shade capable of reducing abnormal noise. Background technique [0002] With the rapid development of China's automobile industry and economic level, automobiles have entered most families in China, and automobiles have become a must-have item for people across the country to travel. Consumers' demand for vehicles is becoming more and more stringent. From the early reliability requirements to the current stage of changes in artificial intelligence and comfort, various comprehensive factors have prompted major automotive R&D centers around the world to devote themselves to Efforts to meet market customer requirements. In the development of vehicle comfort, vehicle abnormal noise is one of the main items. [0003] In China's automobile trend, SUV models are the most representative models. Compared with sedan models, SUV models use more parts, so the probability of abnormal noise is higher...
