Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a central control display screen. Background Technology

[0002] Currently, car center console displays are usually equipped with cameras. Cameras generate a lot of heat during operation, so fans are usually installed inside the center console display to dissipate heat from the cameras.

[0003] However, current heat dissipation methods are not very efficient at cooling cameras and cannot meet the heat dissipation requirements of the central control display screen. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low heat dissipation efficiency of cameras in current automotive center console displays. This invention provides a center console display that effectively solves the problem of low heat dissipation efficiency of cameras in current automotive center console displays.

[0005] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a central control display screen, comprising:

[0006] The casing has a notch;

[0007] A connecting plate is fixed to the housing, and the connecting plate and the housing define an accommodating space. The connecting plate is provided with a clearance opening, and the notch and the clearance opening are arranged opposite to each other along the thickness direction of the central control display screen.

[0008] A camera assembly, a portion of which is located within a notch in the connecting plate, with the clearance opening abutting the camera assembly;

[0009] A fan is located within the aforementioned accommodating space;

[0010] An airflow channel has a first end and a second end, with the fan located at the first end of the airflow channel and the camera assembly located at the second end of the airflow channel.

[0011] By adopting the above technical solution, an airflow channel is set between the fan and the camera component. When the fan generates airflow, the airflow can reach the camera component along the airflow channel to cool the camera component. This effectively improves the heat dissipation efficiency of the camera component, increases the utilization rate of the airflow generated by the fan, and reduces the power requirements of the fan for cooling the camera component.

[0012] According to a specific embodiment of the present invention, along the thickness direction of the central control display screen, the housing is provided with a first rib and a second rib on the side facing the connecting plate, and the first rib and the second rib define the airflow channel.

[0013] According to a specific embodiment of the present invention, the accommodating space has an installation area;

[0014] Along the thickness direction of the central control display screen, the housing has a first protrusion, which protrudes in a direction away from the connecting plate, and the first protrusion is used to abut against the center console of the car.

[0015] Along the thickness direction, the first protrusion and the connecting plate define the mounting area of ​​the accommodating space, and the fan is mounted in the mounting area.

[0016] By adopting the above technical solution, the fan is placed in the mounting area corresponding to the first protrusion (i.e., the non-appearance area), thus effectively reducing the size of the appearance area along the thickness direction.

[0017] According to a specific embodiment of this utility model, the central control display screen further includes:

[0018] A PCB board is fixed to the connecting part, and the PCB board is located in the mounting area, with the fan disposed on one side of the PCB board.

[0019] According to a specific embodiment of the present invention, a groove is formed on the outer surface of the first protrusion, the groove is recessed toward the connecting plate along the thickness direction, and an air inlet is formed in the groove, the air inlet being disposed opposite to the fan along the thickness direction.

[0020] Since the first protrusion abuts against the center console when the central control display screen is installed on the center console, the above-mentioned technical solution is adopted to open a groove on the outer surface of the first protrusion and set the air inlet in the groove. The groove can effectively prevent the center console from blocking the air inlet, so that external air can enter the airflow channel through the air inlet.

[0021] According to a specific embodiment of the present invention, it further includes:

[0022] Two second protrusions are respectively provided on both sides of the notch. The two second protrusions protrude in the direction away from the connecting plate along the thickness direction. The two second protrusions are spaced apart along the length direction of the central control display screen.

[0023] A cover plate is disposed between the two second protrusions, the cover plate and the two second protrusions defining a receiving cavity, and the camera assembly is disposed within the receiving cavity.

[0024] According to a specific embodiment of the present invention, along the width direction of the central control display screen, the two second protrusions are located on one side of the first protrusion;

[0025] The cover plate includes a first part and a second part, wherein the second part is set at an angle to the first part;

[0026] Along the thickness direction, the first part is disposed opposite to the notch of the connecting plate, and along the width direction of the central control display screen, the second part is disposed opposite to the first protrusion.

[0027] According to a specific embodiment of the present invention, the first part is provided with a plurality of heat dissipation vents.

[0028] According to a specific embodiment of the present invention, a wire harness groove is formed on the outer surface of the first protrusion along the thickness direction;

[0029] The two second protrusions and the first portion define the wire harness opening, and along the width direction, the wire harness opening is disposed opposite to and communicates with the wire harness groove.

[0030] According to a specific embodiment of the present invention, it further includes:

[0031] The screen is fixed to the connecting plate, which is located between the screen and the housing along the thickness direction of the central control display screen. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0051] refer to Figures 1 to 3 This application provides a central control display screen 100. In order to facilitate a detailed description of the specific structure of the central control display screen 100, the width direction X, length direction Y and thickness direction Z of the central control display screen 100 are defined here first, wherein the width direction X, length direction Y and thickness direction Z are perpendicular to each other.

[0052] For example, the central control display screen 100 of this application embodiment includes a housing 200, a connecting plate 300, a camera assembly 400, a fan 500, a PCB board 600, and a screen 700. The connecting plate 300 is fixed to the housing 200, and the connecting plate 300 and the housing 200 define an accommodating space 220. Along the width direction X, one side of the housing 200 has a notch 210; correspondingly, along the width direction X, one side of the connecting plate 300 has a clearance opening 310. Along the thickness direction Z, the notch 210 and the clearance opening 310 are arranged opposite to each other. Along the thickness direction Z, the screen 700 is fixed to the side of the connecting plate 300 away from the housing 200 by means such as adhesive; that is, along the thickness direction Z, the connecting plate 300 is located between the screen 700 and the housing 200.

[0053] For example, the camera assembly 400 is disposed within the housing 200, and a portion of the camera assembly 400 is located within the notch 210 of the connecting plate 300. The clearance opening 310 avoids the camera assembly 400, and the camera assembly 400 is attached to the screen 700. It should be noted that "attached" here does not mean pasted with glue, but rather that the camera assembly 400 is attached to the screen 700, that is, the camera assembly 400 is in contact with the screen 700.

[0054] refer to Figure 3 and Figure 4 and combined Figure 1 and Figure 2 The fan 500 is located within the housing space 220 and is capable of generating airflow to cool the camera assembly 400.

[0055] Along the thickness direction Z, the housing 200 has a first rib 233 and a second rib 234 on the side facing the connecting plate 300. The first rib 233 and the second rib 234 are spaced apart and define an airflow channel 230. The airflow channel 230 has a first end 231 and a second end 232. The fan 500 is located at the first end 231 of the airflow channel 230, and the camera assembly 400 is located at the second end 232 of the airflow channel 230.

[0056] Current central control displays on the market place fans directly next to cameras, resulting in a significant amount of airflow not reaching the camera and requiring the fans to have high power to meet the camera's cooling requirements. However, the central control display 100 provided in this embodiment addresses this issue by establishing an airflow channel 230 between the fan 500 and the camera assembly 400. This allows the airflow generated by the fan 500 to reach the camera assembly 400 along the airflow channel 230, effectively cooling the camera assembly 400. This significantly improves the heat dissipation efficiency of the camera assembly 400, increases the utilization rate of the airflow generated by the fan 500, and reduces the power requirements of the fan 500 for cooling the camera assembly 400.

[0057] According to the applicant's tests, current market-ready central control displays (i.e., those without airflow channel 230) require a fan PWM (Pulse Width Modulation) value of 100% (i.e., the fan operates at approximately 100% of its rated speed, i.e., full speed) to meet the heat dissipation requirements of the camera. However, in the central control display 100 provided in this application, the fan 500's PWM value only needs to reach 70% (i.e., the fan 500 operates at approximately 70% of its speed) to meet the heat dissipation requirements of the camera component 400, effectively reducing the energy consumption of the fan 500.

[0058] For example, refer to Figures 1 to 5 In this embodiment of the application, the accommodating space 220 has an installation area 221.

[0059] Specifically, along the thickness direction Z, the housing 200 has a first protrusion 240 that protrudes in a direction away from the connecting plate 300 and is used to abut against the center console of the vehicle (not shown). For example, the first protrusion 240 is located at the middle position of the housing 200.

[0060] Along the thickness direction, the first protrusion 240 and the connecting plate 300 define the mounting area 221 of the accommodating space 220. The fan 500 and the PCB board 600 are both mounted in the mounting area 221, and the fan 500 is located on one side of the PCB board 600.

[0061] It should be noted that the first protrusion 240 is also called the non-exterior area 202. That is to say, when the central control display screen 100 is installed on the center console of the car, since the first protrusion 240 is against the center console of the car, the driver, passengers and people outside the vehicle cannot see the first protrusion 240.

[0062] As the current market demands increasingly higher aesthetic standards for the central control display screen 100, it is necessary to reduce the size of the central control display screen 100 along the thickness direction Z to improve its appearance. However, the camera of the central control display screen 100 is usually located at the top of the central control display screen 100 along the width direction X, that is, the camera is located in the appearance area 201 (i.e., the area visible to the driver, passengers, and people outside the vehicle). At the same time, since current central control displays on the market do not have an airflow channel, the fan needs to be placed close to the camera, which results in a relatively thick size of part of the appearance area 201 along the thickness direction Z, reaching 27.2mm, thus affecting the appearance of the central control display screen 100.

[0063] In this embodiment, because an airflow channel 230 is provided, which can guide the airflow generated by the fan 500 to the camera assembly 400, the central control display screen 100 provided in this embodiment can place the fan 500 within the mounting area 221, that is, the fan 500 is placed in a non-exterior area. Therefore, the size of the exterior area along the thickness direction Z can be effectively reduced. For example, the size of the exterior area 201 along the thickness direction Z of the central control display screen 100 provided in this embodiment is 21.62 mm, which is smaller than the size of the exterior area 201 along the thickness direction Z of the current market central control display screen 100, which is 27.2 mm.

[0064] For example, continue to refer to Figure 1 and combined Figure 3The outer surface 241 of the first protrusion 240 has a groove 242 recessed towards the connecting plate 300 along the thickness direction Z. Five air inlets 243 are provided at the bottom of the groove 242, positioned opposite the fan 500 along the thickness direction Z. When the fan 500 is running, air from outside the central control display screen 100 enters the airflow channel 230 through the air inlets 243 under the drive of the fan 500, and flows towards the camera assembly 400 to cool it.

[0065] Furthermore, since the first protrusion 240 abuts against the center console when the central control display screen 100 is installed on the center console, the groove 242 can effectively prevent the center console from blocking the air inlet 243, so that external gas can enter the airflow channel 230 through the air inlet 243.

[0066] It is understood that the number of air inlets 243 is not specifically limited in this application embodiment and can be adapted to product requirements. For example, in some possible implementations, the number of air inlets 243 may be one, two, three, four or six, etc.

[0067] refer to Figures 1 to 5 The housing 200 also has two second protrusions 250 and a cover plate 260. The two second protrusions 250 are located on the side of the housing 200 away from the connecting plate 300 along the thickness direction Z, and the two second protrusions 250 protrude in the direction away from the connecting plate 300 along the thickness direction. Along the length direction Y of the central control display screen 100, the two second protrusions 250 are spaced apart and respectively located in the notch 210. Along the width direction X, the two second protrusions 250 are located on one side of the first protrusion 240.

[0068] For example, a cover plate 260 is disposed between two second protrusions 250, the cover plate 260 and the two second protrusions 250 defining a receiving cavity 264, in which the camera assembly 400 is disposed.

[0069] Specifically, the cover plate 260 includes a first portion 261 and a second portion 262. The second portion 262 is angled to the first portion 261, and the first portion 261 and the second portion 262 form an approximately L-shape. The present application does not impose special limitations on the included angle between the first portion 261 and the second portion 262, and it can be adaptively adjusted according to the actual needs of the product. For example, in some possible implementations, the included angle between the first portion 261 and the second portion 262 is 70°, 80°, 89°, 90°, 95°, 100°, etc.

[0070] For example, along the thickness direction Z, the first portion 261 is disposed opposite to the notch 210 of the connecting plate 300, and along the width direction X, the second portion 262 is disposed opposite to the first protrusion 240. The first portion 261 is provided with seven heat dissipation vents 263, which are spaced apart along the length direction Y. After the fan 500 is started, the airflow flows along the airflow channel 230 to the camera assembly 400 to dissipate heat and cool the camera assembly 400, and then flows out of the housing 200 through the heat dissipation vents 263.

[0071] Exemplarily, along the thickness direction Z, the outer surface 241 of the first protrusion 240 has a wire harness groove 244, and two second protrusions 250 and the first portion 261 define a wire harness opening 265. Along the width direction W, the wire harness opening 265 is opposite to and communicates with the wire harness groove 244. The camera assembly 400 has a wire harness interface 410 for connecting the camera assembly 400 to external electronic devices. Exemplarily, a wire harness (not shown) extends out of the housing 200 through the wire harness opening 265 and is partially accommodated within the wire harness groove 244.

[0072] For example, the housing 200 also provides two first connecting portions 271 and two second connecting portions 272. Along the length direction Y, the two first connecting portions 271 are respectively provided on opposite sides of the first protrusion 240, and the two second connecting portions 272 are respectively provided on opposite sides of the first protrusion 240. And along the width direction X, each first connecting portion 271 is disposed opposite to one second connecting portion 272.

[0073] The central control display screen 100 is fixed to the center console of the vehicle via a first connecting part 271 and a second connecting part 272. Exemplarily, in this embodiment, the first connecting part 271 has a connecting hole, and the first connecting part 271 can be connected to the center console using fasteners such as screws. The second connecting part 272 is connected to the center console by, for example, a snap-fit ​​connection.

[0074] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
