Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cockpit central control screen protection technology, and specifically to an intelligent cockpit central control screen pressure preservation device and a use method. Background Art

[0002] Most new energy vehicle smart cockpits are equipped with 12.8-inch multimedia central control displays. According to production requirements, the central control display needs to remain stable and firm during vehicle operation, without shaking, and have a good appearance. Therefore, the assembly method of the LCD screen module and the panel decorative frame is very important. The pressure and time of the pressure holding are necessary process links to ensure the firmness of the LCD screen.

[0003] In the related art, the commonly used pressure holding mode is to press down the LCD screen and the panel decorative frame at the same time through a pressure holding device, and take the average value of the pressure holding pressure to ensure the pressure holding effect. However, the decorative frame of the 12.8-inch multimedia central control display screen is divided into a wide side part located in the screen area and a narrow side part located at the edges of the screen. If the pressure is held at the same time, it is easy to cause an imbalance in the distribution of the pressure holding pressure of the wide side decorative frame located in the screen area and the narrow side decorative frame located at the edge of the screen. If the pressure holding pressure is too large, the pressure holding stress of the wide side decorative frame located in the screen area is easy to concentrate, which may easily cause dark damage to the LCD module. The insufficient pressure holding pressure of the narrow side decorative frame located at the edge of the screen may easily cause the VHB glue layer to not be fully activated, thereby causing the LCD screen module and the panel decorative frame to fall apart when the entire vehicle shakes on bumpy roads.

[0021] Example 1: like Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides a smart cockpit central control screen pressure maintaining device, comprising: The mounting frame 7 is used to install a pressure-maintaining device, and includes a lower mounting surface 702, an upper mounting surface 703 provided above the lower mounting surface 702, and a connecting surface 701 for connecting the lower mounting surface 702 and the upper mounting surface 703. The first driving member and the second driving member are both provided on the upper mounting surface 703. The lower mounting surface 702, the connecting surface 701, and the upper mounting surface 703 are integrally provided. The split pressure-maintaining assembly includes a central pressure-maintaining profiling member 1 and a peripheral pressure-maintaining profiling member 2 provided on a mounting frame 7. The central pressure-maintaining profiling member 1 includes a central pressure-maintaining profiling block 101 and a first mounting member 102 provided on the central pressure-maintaining profiling block 101. The peripheral pressure-maintaining profiling member 2 includes a peripheral pressure-maintaining profiling block 202 and a second mounting member 201 provided on the peripheral pressure-maintaining profiling block 202.

[0022] It should be noted here that the peripheral pressure-keeping profiling block 202 is used to maintain the pressure of the narrow side decorative frame part located at the edges of the screen, that is, peripheral pressure-keeping, while the middle pressure-keeping profiling block 101 is used to maintain the pressure of the wide side decorative frame located in the screen area, that is, middle pressure-keeping.

[0023] A driving assembly, the driving assembly includes a first driving member and a second driving member provided on the mounting frame 7, the first driving member being connected to the first mounting member 102, and the second driving member being connected to the second mounting member 201; Specifically, the first driving member includes a middle driving cylinder 3 provided on the upper mounting surface 703, the output end of the middle driving cylinder 3 is detachably connected to the first mounting member 102, and the middle driving cylinder 3 is detachably mounted on the upper mounting surface 703; The second driving member includes a circumferential driving cylinder 5 arranged on the upper mounting surface 703 and located on both sides of the central driving cylinder 3.

[0024] When in use, the middle driving cylinder 3 is started to drive the first mounting part 102 to move downward, so that the middle pressure-maintaining profiling block 101 can be moved downward, thereby maintaining the pressure of the wide-side decorative frame located in the screen area; and the peripheral driving cylinder 5 is started to drive the second mounting part 201 to move downward, which can drive the peripheral pressure-maintaining profiling block 202 to move downward, thereby maintaining the pressure of the narrow-side decorative frame located at the edges of the screen.

[0025] The sample placement assembly is provided on the lower mounting surface 702 and is used to place the semi-finished central control screen to be pressure maintained.

[0026] See also Figure 4 In this embodiment, a pressure detection assembly is provided on both the first mounting member 102 and the second mounting member 201. The pressure detection assembly includes a central pressure sensor 103 and a circumferential pressure sensor 204. The central pressure sensor 103 is provided on the first mounting member 102, and the central pressure-maintaining profiling block 101 is connected to the detection end of the central pressure sensor 103. A connecting block 203 is also provided on the second mounting member 201, and the circumferential pressure sensor 204 is provided at the bottom of the connecting block 203. The circumferential pressure-maintaining profiling block 202 is connected to the detection end of the circumferential pressure sensor 204.

[0027] Specifically, if Figure 2 and Figure 5 As shown, a U-shaped mounting block is integrally provided on the first mounting member 102, and the output end of the middle driving cylinder 3 is fixedly or detachably connected to the mounting block, while the middle pressure sensor 103 is detachably mounted in the mounting block, and its detection end passes through the first mounting member 102 and is fixedly or detachably connected to the middle pressure-maintaining profiling block 101; There are preferably two connecting blocks 203, which are located on both sides of the central pressure-maintaining profiling block 101 respectively. The connecting block 203 and the second mounting member 201 are also integrally arranged. The circumferential pressure sensor 204 is detachably installed in the connecting block 203, and the circumferential pressure-maintaining profiling block 202 is located on the second mounting member 201 and is detachably connected to the circumferential pressure sensor 204.

[0028] It should be noted that there are preferably two circumferential pressure sensors 204 to synchronously detect the holding pressure on both sides of the circumferential pressure-maintaining profiling block 202 to ensure the stability of the pressure. At the same time, there can also be four circumferential pressure sensors 204, which are respectively set at different positions around the circumferential pressure-maintaining profiling block 202 and can be adjusted as needed.

[0029] like Figure 5 As shown, in this embodiment, a floating adjustment component 4 is provided between the first mounting member 102 and the central pressure-maintaining profiling block 101, and between the second mounting member 201 and the peripheral pressure-maintaining profiling block 202. The floating adjustment component 4 includes a plurality of spring rods arranged on the first mounting member 102 and the second mounting member 201. The ends of the spring rods pass through and extend above the first mounting member 102 and the second mounting member 201. The ends of the spring rods are provided with limiting bolts.

[0030] Specifically, there are multiple spring rods arranged in different positions on the upper surfaces of the central pressure-maintaining profiling block 101 and the peripheral pressure-maintaining profiling block 202 in steps. The spring rods, the central pressure-maintaining profiling block 101 and the peripheral pressure-maintaining profiling block 202 are all integrated. The upper end surface of the spring rod passes through the corresponding first mounting member 102 and the second mounting member 201. A threaded groove is also provided on its upper end surface, and a limiting bolt is screwed through the threaded groove. The limiting bolt is mainly used to limit the central pressure-maintaining profiling block 101 and the peripheral pressure-maintaining profiling block 202 so that they are not easily separated from the first mounting member 102 or the second mounting member 201. At the same time, it can also ensure that the gravity of the central pressure-maintaining profiling block 101 and the peripheral pressure-maintaining profiling block 202 still acts on the central pressure sensor 103 or the peripheral pressure sensor 204 when the device is not in use, thereby improving the service life of the central pressure sensor 103 and the peripheral pressure sensor 204.

[0031] In this embodiment, a plurality of guide grooves are further provided on the upper mounting surface 703 , and a plurality of guide rods 6 slidably connected to the corresponding guide grooves are provided on both the first mounting member 102 and the second mounting member 201 .

[0032] The guide rod 6 is fixedly connected to the first mounting member 102 or the second mounting member 201 or is detachably connected to the first mounting member 102 or the second mounting member 201 .

[0033] By providing the guide groove and the guide rod 6 , the middle pressure-maintaining profiling block 101 and the peripheral pressure-maintaining profiling block 202 are made more stable during the pressure-maintaining operation.

[0034] In this embodiment, both the first driving member and the second driving member are provided with a pressure regulating assembly, and the pressure regulating assembly includes multiple pressure regulating valves, which are respectively arranged on the air inlet ends of the central driving cylinder 3 and the peripheral driving cylinder 5.

[0035] Specifically, the pressure regulating valve can adjust the air intake volume of the central drive cylinder 3 and the peripheral drive cylinder 5, thereby realizing the adjustment of the output pressure. This is a technical solution that has been disclosed in the prior art. The present application can respectively detect the holding pressure of the wide side decorative frame located in the screen area and the narrow side decorative frame located at the edge of the screen through the central pressure sensor 103 and the peripheral pressure sensor 204. The holding pressure of different areas can be adjusted to an appropriate range through the pressure regulating valve, so that the holding pressure of different positions of the central control screen to be held can meet the actual needs, which not only ensures the product production requirements, but also protects the product, and at the same time improves the quality after holding.

[0036] See also Figure 6 and Figure 7 In this embodiment, the sample placement assembly includes a workpiece placement plate 8 arranged on the lower mounting surface 702, and a placement groove 9 is provided on the workpiece placement plate 8. Limit blocks 10 are provided at the four edges of the placement groove 9. The side of the limit block 10 that contacts the central control screen to be pressurized is rounded, and waist openings 11 are also provided on both sides of the placement groove 9.

[0037] Among them, the placement groove 9 is used to place the central control screen to be pressurized, and the limit blocks 10 are fixed at the four edges of the placement groove 9. The multiple limit blocks 10 are used to limit the central control screen, so that it is not easy to offset during the pressure holding process, resulting in pressure holding failure. The waist opening 11 is set to facilitate the placement of the central control screen to be pressurized in the placement groove 9.

[0038] In addition, a soft pad is provided on the side of the placement groove 9 that contacts the screen of the central control screen to be pressurized to protect the screen from being damaged under the pressurization pressure. The material of the soft pad is preferably anti-static polyurethane material with a hardness of Shore A70.

[0039] This embodiment also provides a method for using the intelligent cockpit central control screen pressure maintaining device, comprising the following steps: Place the semi-finished central control panel to be pressurized into the placement slot 9 and limit it with the limit block 10; Set the pressure holding order to first hold the periphery and then the center, and set the pressure holding time for each; Start the circumferential drive cylinder 5 to drive the second mounting part 201 to move downward, and first maintain pressure on the narrow decorative frame of the edge part of the semi-finished central control screen to be pressurized through the circumferential pressure-maintaining profiling block 202. The circumferential pressure sensor 204 can monitor the pressure-maintaining pressure in real time, and start the corresponding pressure-regulating valve to adjust the output pressure of the circumferential drive cylinder 5 so that the circumferential pressure-maintaining pressure is maintained at an appropriate position. After the pressure-maintaining time is reached, the circumferential drive cylinder 5 drives the second mounting part 201 to reset. At the same time, the central drive cylinder 3 drives the central pressure-maintaining profiling block 101 to maintain pressure again on the wide side decorative frame of the screen area of ​​the semi-finished central control screen to be pressurized. The central pressure sensor 103 can monitor the pressure-maintaining pressure in the middle in real time, and start the corresponding pressure-regulating valve to adjust the output pressure of the central drive cylinder 3 so that the central pressure-maintaining pressure is maintained at an appropriate position. After the pressure-maintaining time is reached, the central drive cylinder 3 drives the central pressure-maintaining profiling block 101 to reset. Take out the central control screen after pressure holding is completed.

[0040] Example 2: The difference from the first embodiment is that the order of pressure holding is different. Specifically: Place the semi-finished central control panel to be pressurized into the placement slot 9 and limit it with the limit block 10; Set the pressure holding sequence to first hold the center and then the periphery, and set the pressure holding time for each; Start the middle driving cylinder 3 to drive the middle pressure-holding profiling block 101 to maintain pressure on the wide side decorative frame of the screen area of ​​the semi-finished central control screen to be pressurized. The middle pressure sensor 103 can monitor the pressure-holding pressure in the middle in real time, start the corresponding pressure-regulating valve to adjust the output pressure of the middle driving cylinder 3 so that the middle pressure-holding pressure is maintained at an appropriate position. After the pressure-holding time is reached, the middle driving cylinder 3 drives the middle pressure-holding profiling block 101 to reset, and then starts the circumferential driving cylinder 5 to drive the second mounting part 201 to move downward, and the narrow side decorative frame of the peripheral edge part of the semi-finished central control screen to be pressurized is maintained again through the circumferential pressure-holding profiling block 202. The circumferential pressure sensor 204 can monitor the pressure-holding pressure in real time, start the corresponding pressure-regulating valve to adjust the output pressure of the circumferential driving cylinder 5 so that the circumferential pressure-holding pressure is maintained at an appropriate position. After the pressure-holding time is over, the circumferential driving cylinder 5 drives the circumferential pressure-holding profiling block 202 to reset; Take out the central control screen after pressure holding is completed.
