Description

Technical Field

[0001] This invention relates to the field of display components for multimedia hosts, specifically a display component for an in-vehicle multimedia host. Background Technology

[0002] The car's central control unit is where you control the car's air conditioning, audio system, and other comfort and entertainment features. It also includes a central locking system, allowing the driver to control all the car's doors and windows.

[0003] Since typical central control devices are fixed and cannot be adjusted in angle, drivers of different heights may need to view the central control screen from different angles. This can lead to some drivers not being able to see the central control screen clearly, resulting in dangerous operations and increasing driving hazards. In addition, when a typical in-vehicle central control screen is damaged, it requires time and effort to remove and repair it. Sometimes, improper operation can damage the central control screen, and the process is inefficient. Furthermore, after prolonged use or exposure to sunlight, the in-vehicle display device may experience a blackout or system crash due to excessive heat, preventing the driver from obtaining useful information while driving. Therefore, it is necessary to cool down the central control screen. Summary of the Invention

The rotating shaft is fixedly connected to the central control screen. A sliding rod is slidably connected inside the rotating shaft. A first limiting groove is provided at the bottom end of the rotating shaft. A gear is fixedly connected to the sliding rod and is slidably connected to the first limiting groove. A second limiting groove is provided at the top end of the rotating shaft and the gear engages with the second limiting groove. A pressing block is fixedly connected to the top end of the sliding rod and is slidably connected to the protective plate. A first spring is fixedly connected between the pressing block and the protective plate. The gear has a convex trapezoidal cross-section, and the second limiting groove has a concave trapezoidal cross-section.

[0008] Specifically, the disassembly structure includes a first insert rod. Two first insert rods are fixedly connected to the side end of the protective plate, and both first insert rods are parallel and symmetrical. Each first insert rod is inserted into the back plate. A locking block is slidably connected to the bottom end of the back plate, engaging with the protective plate. A second spring is fixedly connected between the locking block and the back plate. A first slider is slidably connected inside the protective plate, with a contact block fixedly connected to the bottom end of the first slider. A limit block is slidably connected inside the protective plate, engaging with the locking block. A stop block is fixedly connected to the bottom end of the limit block. A third spring is fixedly connected between the stop block and the protective plate. An adjusting block is fixedly connected to the stop block, slidably connected to the protective plate. The top end of the adjusting block abuts against the first slider. The top cross-sections of both sides of the first slider and the top cross-section of the adjusting block are arc-shaped.

[0009] Specifically, the heat dissipation structure includes an air inlet, the back plate is provided with an air inlet, a second slider is detachably connected inside the back plate, and two second sliders are provided in a parallel and symmetrical relationship. A motor is installed in each of the two second sliders, and a fan blade is fixedly connected to the output end of the motor. A first filter screen is fixedly connected to the second slider.

[0010] Specifically, the filter structure includes a second filter screen, which is detachably connected to the inner side of the back plate. A retaining ring is fixedly connected to the side end of the second filter screen, and a retaining groove is provided in the retaining ring. A retaining rod is fixedly connected to the inner side of the back plate, and two retaining rods are provided in a parallel and symmetrical relationship. The retaining rods engage with the retaining grooves.

[0011] Specifically, the abutting structure includes a fixing block, and the fixing block is fixedly connected inside the back plate. The fixing blocks are arranged in a parallel and symmetrical structure with two blocks. A third slider is slidably connected to each of the two fixing blocks. The third slider engages with the second slider. A fourth spring is fixedly connected between the third slider and the fixing block.

[0012] The beneficial effects of this invention are:

[0013] (1) The display component of the vehicle multimedia host of the present invention has a rotating structure and a limiting structure on the central control screen that can adjust the angle; the viewing angle of the central control screen can be adjusted by the rotating structure, and the angle of the central control screen can be fixed by the limiting structure. That is, pressing the pressing block compresses the first spring, and the sliding rod drives the gear to separate from the second limiting groove of the rotating shaft. When the gear reaches the first limiting groove, the central control screen is rotated. The central control screen rotates on the protective plate through the rotating shaft at the bottom and the rotating shaft at the top, and the angle of the central control screen can be adjusted. The gear also engages with the second limiting groove to fix the central control screen.

[0014] (2) The display component of the vehicle multimedia host of the present invention has a disassembly structure and a contact structure at the bottom of the rotating structure; the central control screen can be disassembled by the disassembly structure, and the heat dissipation structure can be fixed and replaced by the contact structure. That is, when the central control screen needs to be disassembled, the first slider is pressed, and the top of both sides of the first slider will contact the adjustment block, so that the adjustment block drives the stop block to squeeze the third spring. The stop block drives the limit block at the same time, so that the limit block separates from the card block. When the contact block pushes the card block into the back plate, the protective plate slides outward, which drives the central control screen to separate the first plug rod from the back plate, thereby completing the disassembly of the central control screen. Since the first plug rod is separated from the back plate, the third slider slides on the fixed block under the action of the fourth spring and separates from the second slider, so that the second slider can be pulled out from the back plate for cleaning or maintenance of the motor and fan blades.

[0015] (3) The display component of the vehicle multimedia host of the present invention has a heat dissipation structure on the rotating structure; thereby, the heat dissipation structure can dissipate heat on the central control screen, that is: cold air can enter the back panel through the air inlet of the back panel through the second filter screen, and then the hot air is sent to the outside of the back panel through the motor and fan blades of the second slider screen, thereby completing the cooling of the central control screen.

[0016] (4) The display component of the vehicle multimedia host of the present invention has a filter structure installed on the side of the rotating structure; thus, the dust can be filtered out through the filter structure, that is: the dust in the air inlet is filtered out through the second filter screen, and the dust near the bolt can be cleaned to prevent the bolt from being difficult to disassemble due to the accumulation of dust near the bolt. At the same time, the second filter screen can be replaced by the engagement and disengagement of the retaining ring and the retaining rod. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, the display component of an in-vehicle multimedia host according to the present invention includes a central control screen 1, a rotating structure 2 installed on the central control screen 1; a limiting structure 3 is provided inside the rotating structure 2; a disassembly structure 4 is detachably connected inside the rotating structure 2; a heat dissipation structure 5 is detachably connected to one side of the rotating structure 2; a filter structure 6 is detachably connected to the heat dissipation structure 5; and an abutment structure 7 is installed inside the rotating structure 2.

[0027] Specifically, the rotating structure 2 includes a protective plate 201, which is rotatably connected to the central control screen 1. A rotating shaft 202 is rotatably connected to the inner side of the protective plate 201. The rotating shaft 202 is fixedly connected to the bottom end of the central control screen 1. A back plate 203 is slidably connected to the inner side of the protective plate 201. A base 204 is fixedly connected to the side end of the back plate 203. A dustproof pad 205 is fixedly connected to the central control screen 1 and is fixedly connected to the inner side of the protective plate 201. Thus, the angle of the central control screen 1 can be adjusted by the rotating structure 2, that is, by rotating the central control screen 1 on the protective plate 201 via the rotating shaft 202 at the bottom end.

[0028] Specifically, the limiting structure 3 includes a rotating shaft 301, which is rotatably connected to the side end of the protective plate 201. The rotating shaft 301 is fixedly connected to the central control screen 1. A sliding rod 302 is slidably connected inside the rotating shaft 301. A first limiting groove 303 is provided at the bottom end of the rotating shaft 301. A gear 304 is fixedly connected to the sliding rod 302 and is slidably connected to the first limiting groove 303. A second limiting groove 305 is provided at the top end of the rotating shaft 301, and the gear 304 engages with the second limiting groove 305. A pressing block 306 is fixedly connected to the top end of the sliding rod 302 and is slidably connected to the protective plate 201. A first spring 307 is fixedly connected between the pressing block 306 and the protective plate 201. The gear 304 has a convex cross-section. The trapezoidal structure, with the second limiting groove 305 having a concave trapezoidal cross-section; thus, the angle of rotation of the central control screen 1 can be fixed through the limiting structure 3, that is: pressing the pressing block 306 compresses the first spring 307, and the sliding rod 302 drives the gear 304 to separate from the second limiting groove 305 of the rotating shaft 301. When the gear 304 reaches the first limiting groove 303, the central control screen 1 is rotated. The central control screen 1 rotates on the protective plate 201 through the rotating shaft 202 at the bottom and the rotating shaft 301 at the top, which can adjust the angle of the central control screen 1. After the angle is adjusted, the pressing block 306 is released, and the pressing block 306 returns to its original position under the action of the first spring 307. The gear 304 also engages with the second limiting groove 305, fixing the central control screen 1 in reverse.

[0029] Specifically, the disassembly structure 4 includes a first insert rod 401. The protective plate 201 has two first insert rods 401 arranged in a parallel and symmetrical manner. Both first insert rods 401 are inserted into the back plate 203. A locking block 402 is slidably connected to the bottom of the back plate 203. The locking block 402 engages with the protective plate 201. A second spring 403 is fixedly connected between the locking block 402 and the back plate 203. A first slider 404 is slidably connected within the protective plate 201. A contact block 405 is fixedly connected to the bottom of the first slider 404. A limit block 406 is slidably connected within the protective plate 201. The limit block 406 is inserted into a locking block 402. A stop block 407 is fixedly connected to the bottom of the limit block 406. A third spring 408 is fixedly connected between the stop block 407 and the protective plate 201. An adjusting block 409 is fixedly connected to the stop block 407. The adjusting block 409 is slidably connected to the protective plate 201. The top of the adjusting block 409 abuts against the first slider 404. The top sections of both sides of the first slider 404 have an arc-shaped cross-section, and the top section of the adjusting block 409 also has an arc-shaped cross-section. The central control screen 1 can then be disassembled via the disassembly structure 4. That is, when the central control screen 1 needs to be disassembled and replaced, pressing the first slider 404 will cause the top sections of both sides of the first slider 404 to abut against the adjusting block 409. Continuing to press the first slider 404 will allow the adjusting block 409 to abut against the adjusting block 409. Block 409 drives stop 407 to compress the third spring 408. Stop 407 simultaneously drives limit block 406, causing limit block 406 to separate from locking block 402. Locking block 402 will not fall out of the back plate 203 under the action of the second spring 403. When the abutment block 405 pushes locking block 402 into the back plate 203, the protective plate 201 slides outward, causing the central control screen 1 to separate the first insertion rod 401 from the back plate 203, thereby completing the disassembly of the central control screen 1.

[0030] Specifically, the heat dissipation structure 5 includes an air inlet 501, which is provided on the back plate 203. A second slider 502 is detachably connected inside the back plate 203, and two second sliders 502 are arranged in a parallel and symmetrical relationship. A motor 503 is installed inside each of the two second sliders 502. A fan blade 504 is fixedly connected to the output end of each motor 503. A first filter 505 is fixedly connected to each second slider 502. Thus, the heat dissipation structure 5 can dissipate heat from the central control screen 1. That is, the motor 503 and fan blades 504 of the second slider 502 send hot air out through the first filter 505 to the outside of the back plate 203, and then through the air inlet 501 of the back plate 203, cold air can enter the interior of the back plate 203 through the second filter 601. At the same time, the air inlet 501 can also absorb dust near the bolts on the base 204 into the interior of the back plate 203 and filter it out through the second filter 601, preventing the bolts from being difficult to disassemble due to the accumulation of dust near the bolts, thus completing the cooling of the central control screen 1.

[0031] Specifically, the filter structure 6 includes a second filter screen 601, which is detachably connected to the inner side of the back plate 203. A retaining ring 602 is fixedly connected to the side end of the second filter screen 601, and a retaining groove 603 is provided in the retaining ring 602. A retaining rod 604 is fixedly connected to the inner side of the back plate 203, and two retaining rods 604 are provided in a parallel and symmetrical relationship. The retaining rods 604 engage with the retaining groove 603. Thus, the filter structure 6 can filter dust and prevent it from entering the interior of the central control screen 1. That is, the second filter screen 601 filters out dust, preventing the bolts from being difficult to disassemble due to dust accumulation near the bolts. At the same time, the retaining rod 604 slides out from the retaining groove 603 inside the retaining ring 602, thereby removing the second filter screen 601 for cleaning.

[0032] Specifically, the contact structure 7 includes a fixing block 701. The fixing block 701 is fixedly connected inside the back plate 203, and there are two fixing blocks 701 arranged in a parallel and symmetrical structure. A third slider 702 is slidably connected to each of the two fixing blocks 701. The third slider 702 engages with the second slider 502. A fourth spring 703 is fixedly connected between the third slider 702 and the fixing block 701. Thus, the heat dissipation structure 5 can be cleaned, replaced, and fixed through the contact structure 7. That is, under the action of the fourth spring 703, the third slider 702 slides on the fixing block 701 and separates from the second slider 502, so that the second slider 502 can be pulled out from the back plate 203 for cleaning or maintenance of the motor 503 and the fan blade 504. At the same time, the first insert rod 401 abuts against the third slider 702, so that the third slider 702 engages with the second slider 502, thereby fixing the second slider 502.

[0033] In use, the present invention first fixes the display device to the vehicle using bolts on the base 204. A backplate 203 is mounted on the base 204. The motor 503 is started, and through the motor 503 and fan blades 504 of the second slider 502, hot air is delivered to the outside of the backplate 203 via the first filter 50. Then, cool air enters the backplate 203 through the air inlet 501 via the second filter 601. Simultaneously, the air inlet 501 also draws dust near the bolts on the base 204 into the backplate 203, where it is filtered out by the second filter 601, preventing dust accumulation near the bolts from making them difficult to remove. This completes the cooling of the central control screen 1. When the angle of the central control screen 1 needs to be adjusted, the pressing block 3 is pressed. 06. The first spring 307 is compressed, which drives the gear 304 to separate from the second limiting groove 305 of the rotating shaft 301 via the slide rod 302. When the gear 304 reaches the first limiting groove 303, the central control screen 1 is rotated. The central control screen 1 rotates on the protective plate 201 via the rotating shaft 202 at the bottom and the rotating shaft 301 at the top, which can adjust the angle of the central control screen 1. At the same time, the dustproof pad 205 between the central control screen 1 and the protective plate 201 is stretchable, which can protect the inside and rear of the central control screen 1 and prevent dust from entering. After the angle is adjusted, the pressing block 306 is released. Under the action of the first spring 307, the pressing block 306 returns to its original position, and the gear 304 also engages with the second limiting groove 305. Due to the cross-section of the gear 304... The first limiting groove 305 is convex trapezoidal, while the second limiting groove 305 has a concave trapezoidal cross-section. This prevents the gear 304 from failing to engage with the second limiting groove 305 without the action of the first spring 307, thus preventing the central control screen 1 from being fixed at an angle. When the central control screen 1 needs to be disassembled, first press the first slider 404. The tops on both sides of the first slider 404 will abut against the adjusting block 409. Continue pressing the first slider 404, causing the adjusting block 409 to drive the stop block 407 to compress the third spring 408. The stop block 407 simultaneously drives the limiting block 406, causing the limiting block 406 to separate from the locking block 402. The locking block 402 will not fall out of the back plate 203 under the action of the second spring 403. When the abutting block 405 pushes the locking block 402 into the back plate 203... Slide the protective plate 201 outwards, causing the central control screen 1 to separate the first insertion rod 401 from the back plate 203, thus completing the disassembly of the central control screen 1. This eliminates the need to remove bolts to remove the central control screen 1, making the operation simple and convenient. Simultaneously, when the central control screen 1 is removed, due to the separation of the first insertion rod 401 from the back plate 203, the third slider 702 slides on the fixed block 701 under the action of the fourth spring 703, separating from the second slider 502. This allows the second slider 502 to be pulled out of the back plate 203, enabling cleaning or maintenance of the motor 503 and fan blades 504. Simultaneously, the filter structure 6 can also be cleaned. Press the locking rods 604 at both ends of the second filter screen 601, causing the locking rods 604 to tilt, and then pull the retaining ring 602 outwards.This causes the retaining rod 604 to slide out of the retaining groove 603 inside the retaining ring 602, thereby removing the second filter screen 601 for cleaning. When installation is required, the retaining ring 602 is pressed against the retaining rod 604, causing the retaining rod 604 to engage with the retaining groove 603, completing the installation of the second filter screen 601. Then, when installing the second slider 502, the second slider 502 is placed inside the back plate 203, and the retaining block 402 is pressed, causing the retaining block 402 to enter the back plate 203. Then, the protective plate 201 is pushed, causing the first insert rod 401 to insert into the back plate 203. Next, the first insert rod 401 abuts against the third slider 702, causing the third slider 702 to engage with the second slider 502, thereby fixing the second slider 502 and preventing it from moving, thus completing the fixing of the motor 503. Simultaneously, when the first insert rod 401 is inserted into the back plate 203, the locking block 402 moves downward under the action of the second spring 403, and then engages with the limiting block 406, preventing the locking block 402 from moving downward again. This process of fixing the second slider 502 and simultaneously installing the central control screen 1 is simple and convenient.
