Description

Technical Field

[0001] The utility model belongs to the field of electronic product accessories, and particularly relates to a door assembly applicable to a storage bin of a vehicle-mounted folding screen. Background Art

[0002] Nowadays, new energy vehicles are generally popular with large-sized screens installed. However, in a carriage with limited space, the large-sized screen has a large volume, which easily occupies the passenger's sitting space, affects the sitting experience, and also causes a certain blockage to the driver's line of sight. Therefore, engineers consider applying the folding screen technology to vehicle-mounted screens. The vehicle-mounted screen can extend out of the receiving cavity and unfold for use; when not in use, the vehicle-mounted screen folds and retracts into the receiving cavity for storage.

[0003] For example, there is a Chinese patent with the publication number CN113335194A, which relates to an intelligent cockpit with a folding screen, and discloses an instrument panel having a receiving cavity; a screen assembly including a first display screen and a second display screen; a driving device, and the screen assembly is converted between a first state and a second state under the action of the driving device; a hanging curtain made of an elastic material is arranged at the opening of the receiving cavity of the instrument panel, and the hanging curtain is used to block the opening of the receiving cavity. Specifically, the hanging curtain is made of a rubber sheet, its upper end is fixed to the upper wall of the opening of the receiving cavity, and the lower end abuts against the lower wall position of the opening of the receiving cavity; when the first display screen and the second display screen enter or extend out of the receiving cavity, when they horizontally move through the opening position, the hanging curtain flips horizontally. When the first display screen and the second display screen are in the first state inside the receiving cavity or the second state outside the receiving cavity, the hanging curtain naturally hangs down to block the opening to prevent dust from falling into the receiving cavity.

[0004] However, in the actual use process, the prior art is prone to the following defects:

[0005] 1. When the display screen extends out or retracts into the receiving cavity, it inevitably comes into contact with the hanging curtain made of elastic material. That is to say, it is easy to generate friction between the display screen and the hanging curtain, which hinders the movement of the display screen and further increases the load of the motor.

[0006] 2. Under accidental touch or the inertia formed by sudden braking of the vehicle, the hanging curtain is very easy to open inward, resulting in the opening of the receiving cavity being exposed, and the probability of dust and other foreign objects falling into the receiving cavity is relatively high. Summary of the Invention

[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an improved door assembly applicable to a storage bin of a vehicle-mounted folding screen.

[0008] To solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A door assembly suitable for a vehicle-mounted folding screen storage bin, which includes a front end plate having a bin opening for the folding screen to enter and exit, a door movably connected to the front end plate and matching the bin opening, and a driving component. The driving component includes a driving wheel, one or more driven wheels, and a transmission belt that sequentially bypasses the driving wheel and the driven wheels. The transmission belt has a connecting section extending along the moving direction of the door. The door is fixedly connected to the connecting section and synchronously opens or closes the bin opening as the transmission belt moves.

[0010] According to a specific implementation and preferred aspect of the present utility model, the door is arranged on the inner wall of the front end plate and reciprocates along the width direction of the bin opening. Here, the door is built-in to improve the simplicity of the external structure and the aesthetics.

[0011] Preferably, two sliding rails are provided on the inner wall of the front end plate on opposite sides in the length direction of the bin opening. The two sliding rails respectively extend along the width direction of the bin opening, and the door is slidably connected to the two sliding rails correspondingly from opposite sides. Here, the opening and closing movement path of the door is short, which is convenient for installation and implementation in a narrow space.

[0012] Preferably, two insertion slots are respectively provided on opposite sides of the door at intervals along the extending direction of the sliding rail. Two sliding blocks corresponding to the two insertion slots are respectively provided on the two sliding rails. The two sliding blocks on each side are correspondingly inserted into the two insertion slots and slide along the sliding rail synchronously as the door moves.

[0013] Preferably, a groove extending outward from the inner wall is formed on the front end plate, the bin opening is located at the bottom of the groove, and the door is movably arranged in the groove. Here, the movement area of the door is limited to prevent the door from excessive displacement.

[0014] According to another specific implementation and preferred aspect of the present utility model, a connection module is fixedly provided on one side of the door. A channel matching the connecting section is formed in the connection module, and the connecting section passes through the channel and is relatively fixed to the channel.

[0015] Preferably, engaging teeth are respectively provided on a corresponding side surface of one side of the channel and the connecting section. Here, the movement of the door is realized through gear transmission, and the transmission is reliable and stable.

[0016] Specifically, a guiding groove extending along the length direction of the connecting section is formed on the other side surface of the channel, and the connecting section is located in the guiding groove. Here, the stability of the connecting section of the transmission belt is improved through the guiding groove.

[0017] Preferably, the driving component further includes a base. Two connecting ears are formed on the base at intervals along the moving direction of the door. There are two driven wheels which are correspondingly rotatably connected to the two connecting ears, and the transmission belt between the two driven wheels forms the connecting section. The connection line between the driving wheel and the two driven wheels forms a triangle.

[0018] Specifically, an adjustment groove extending along a direction perpendicular to the connection section is further formed on the base, and the driving wheel can be adjusted along the adjustment groove in a direction closer to or farther from the connection section and fixed on the base. Herein, it is convenient to adjust the surface tension of the transmission belt to match the wear degree of the transmission belt and extend the service life.

[0019] Due to the implementation of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0020] In the prior art, when the display screen extends out or retracts into the accommodation cavity, it inevitably comes into contact with the hanging curtain made of elastic material. That is to say, it is easy to generate frictional force between the display screen and the hanging curtain, which hinders the movement of the display screen and further increases the load of the motor; when the hanging curtain is accidentally touched or under the inertia formed by the sudden braking of the vehicle, it is very easy to open inward, resulting in the opening of the accommodation cavity being open, and the probability of foreign matters such as dust falling into the accommodation cavity is relatively high. However, the present application conducts an overall design on the door assembly applicable to the vehicle-mounted folding screen storage bin, skillfully solves the deficiencies and defects of the prior art. After adopting this door assembly, when opening the door, through the cooperation of the driving wheel and the driven wheel, the transmission belt is driven to drive, and the door fixed to the connection section on the transmission belt moves synchronously and opens the hatch to allow the folding screen to extend out; when closing the door, again through the cooperation of the driving wheel and the driven wheel, the transmission belt is driven in the reverse direction, so that the door is reset and the hatch is closed. Therefore, compared with the prior art, on the one hand, based on the cooperative transmission of the driving wheel, the driven wheel and the transmission belt, the present utility model realizes the automatic opening or closing of the hatch by the door, thereby avoiding contact with the folding screen, ensuring the smooth extension or retraction of the folding screen, and at the same time greatly improving the sealing degree of the door to the hatch and reducing the probability of foreign matters entering the storage bin; on the other hand, the structure is simple and reliable, which is convenient for installation and implementation in the narrow carriage space.

[0035] As Figures 1 to 4 shown, the door assembly applicable to the in-vehicle folding screen storage bin involved in this embodiment includes a front end plate 1, a door 2 and a driving component 3 arranged at the front end of the storage bin C.

[0036] Specifically, a bin opening 10 for the folding screen to enter and exit is formed on the front end plate 1; the door 2 is movably connected to the front end plate 1 and matches the bin opening 10.

[0037] For the convenience of implementation, the door 2 is arranged on the inner wall of the front end plate 1 and is reciprocally arranged along the width direction of the bin opening 10; two slide rails g are provided on the inner wall of the front end plate 1 on the opposite sides in the length direction of the bin opening 10, and the two slide rails g respectively extend along the width direction of the bin opening 10, and the door 2 is slidably connected to the two slide rails g correspondingly from the opposite sides.

[0038] In some specific embodiments, two insertion slots 20 are respectively provided on opposite sides of the bin door 2 at intervals along the extending direction of the slide rail g. Two sliders k corresponding to and mating with the two insertion slots 20 are respectively provided on the two slide rails g. The two sliders k on each side are correspondingly inserted into the two insertion slots 20 and slide along the slide rail g synchronously with the movement of the bin door 2.

[0039] Meanwhile, a groove 11 extending outward from the inner wall surface is formed on the front end plate 1, and the bin opening 10 is located at the bottom of the groove 11.
