Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a cover assembly and a secondary instrument panel provided thereon. Background Technology

[0002] In related technologies, an elbow rest is typically integrated into the secondary instrument, and the elbow rest housing is usually integrated with the secondary instrument housing as a single unit. The portion of the secondary instrument corresponding to the elbow rest typically includes a housing with a receiving cavity, a cover plate located at the top opening of the housing, and a drive structure for driving the cover plate. Driven by the drive structure, the cover plate can be retracted into the housing and open the top opening, or removed from the housing to close the top opening. However, existing cover plate drive structures are complex, bulky, occupy a large amount of housing space, and are costly, which is detrimental to improving the internal space utilization of the secondary instrument and achieving cost reduction design. Utility Model Content

[0003] In view of this, this application aims to propose a cover assembly that improves the space utilization of the sub-instrument while also facilitating cost reduction design.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows: A cover assembly for use in a vehicle's auxiliary instrument panel includes a cover panel disposed on a housing of the auxiliary instrument panel, and a cover panel drive mechanism and a cover panel transmission mechanism disposed in the housing. The cover plate transmission mechanism includes a pulley block and a cable wound around the pulley block, and the cover plate drive mechanism is connected to the cover plate through the cable; Driven by the cover plate driving mechanism, the cover plate can be switched to a first position covering the top of the housing, or retracted to a second position inside the housing.

[0005] Furthermore, a guide slide is integrated on the inner wall of the housing; a sliding part is provided on the cover plate, and the sliding part slides in cooperation with the guide slide; the guide slide is configured to guide the cover plate to move between a first position and a second position.

[0006] Furthermore, the cover plate includes a first cover plate and a second cover plate, the sliding part includes a first sliding unit and a second sliding unit disposed on the first cover plate, and a third sliding unit and a fourth sliding unit disposed on the second cover plate; the guide slide includes a first sub-guide slide, a second sub-guide slide, and a third sub-guide slide arranged sequentially; the first sliding unit is slidably disposed in the first sub-guide slide, the second sliding unit and the third sliding unit are both slidably disposed in the second sub-guide slide, the fourth sliding unit is slidably disposed in the third sub-guide slide, and a connecting rod is provided between the second sliding unit and the third sliding unit, one end of the connecting rod is hinged to the second sliding unit, and the other end of the connecting rod is hinged to the third sliding unit.

[0007] Furthermore, the pulley assembly includes at least three fixed pulleys disposed in the housing, and the cable is wound sequentially around each of the fixed pulleys.

[0010] Furthermore, the electromagnetic locking mechanism includes an electromagnet assembly disposed on the housing and a locking tongue driven by the electromagnet assembly; when the cover plate reaches the first position, the electromagnet assembly is energized and activated to drive the locking tongue to extend and lock the cover plate.

[0011] Compared with the prior art, this application has the following advantages: (1) The cover plate assembly described in this application uses a combination of pulley blocks and cables to drive the cover plate, so that the cover plate is in a first position that is sealed on the top of the housing or in a second position that is stored in the housing under the drive of the cover plate drive mechanism. This not only facilitates the electric drive of the cover plate and enhances the technological and ceremonial feel of the auxiliary instrument, but also the cable has flexible buffering characteristics that can absorb the impact and vibration during the drive process and reduce noise. At the same time, the structure is simple, which can also help reduce the space occupied in the housing, improve space utilization, and facilitate cost reduction design.

[0012] (2) The use of guide rails and sliding parts together can help improve the stability of the cover plate movement.

By changing the arrangement of each fixed pulley, the direction of the tension force on the cable can be realized, so as to realize the preset drive path of the cover plate, that is, to realize the cover plate being completely stored in the shell on one side. At the same time, the use of fixed pulleys can also ensure the stability of force transmission.

[0016] (6) The cover plate drive mechanism includes a drive motor and a drive wheel. One end of the cable is wound around the drive wheel, which can realize the smooth drive of the cable, reduce friction and wear, and thus help reduce the failure rate.

[0023] In addition, the tea table is height-adjustable, allowing it to be raised to a suitable position for the user when the cover is opened, and then lowered into the housing and concealed by the cover. This improves safety when using the tea table while driving, makes better use of the interior space, and allows the tea table to blend better into the cabin environment, enhancing the technological and ceremonial feel of the instrument panel.

In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides a cover assembly, which is particularly suitable for the auxiliary instrument panel of a vehicle. It not only reduces the space occupied in the housing, improves space utilization, and helps reduce costs, but also has low operating noise and good performance.

[0032] In related technologies, an elbow rest is typically integrated into the secondary instrument panel, and the elbow rest housing is usually integrated with the secondary instrument panel housing as a single unit. The portion of the secondary instrument panel corresponding to the elbow rest typically includes a housing with a receiving cavity, a cover plate located at the top opening of the housing, and a drive structure for driving the cover plate. Driven by the drive structure, the cover plate can be retracted into the housing and open the top opening, or removed from the housing to seal the top opening. The drive structure typically employs a transmission form involving a power wheel and connecting rod assembly, or a balance wheel and balance rod. This makes the existing cover plate drive structure complex, bulky, and occupies a large space in the secondary instrument panel housing, resulting in high costs and hindering the improvement of the internal space utilization of the secondary instrument panel and cost reduction.

[0033] In view of this, in order to overcome the shortcomings of the prior art, the cover plate assembly of this embodiment combines... Figures 1 to 9 As shown, the overall design includes a cover plate 400 disposed on the housing 100 of the auxiliary instrument, and a cover plate drive mechanism 500 and a cover plate transmission mechanism disposed in the housing 100.

[0034] The cover plate transmission mechanism includes a pulley block 504 and a cable 503 wound around the pulley block 504. The cover plate drive mechanism 500 is connected to the cover plate 400 via the cable 503. Driven by the cover plate drive mechanism 500, the cover plate 400 can be switched to a first position covering the top of the housing 100, or retracted to a second position inside the housing 100.

[0035] Therefore, by using the combination of pulley block 504 and cable 503 to drive the cover plate 400, the cover plate 400, driven by the cover plate drive mechanism 500, has a first position covering the top of the housing 100, or a second position stored in the housing 100. This not only facilitates the electric drive of the cover plate 400, enhancing the technological and ceremonial feel of the auxiliary instrument, but also the cable 503 has flexible buffering characteristics, which can absorb the impact and vibration during the drive process and reduce noise. At the same time, the simple structure also helps to reduce the space occupied in the housing 100, improve space utilization, and facilitate cost reduction design, thus making the cover plate assembly have a better performance.

[0036] Based on the above general introduction, specifically, in some exemplary embodiments, the cover assembly of this embodiment is particularly suitable for a vehicle's secondary instrument panel, especially for positioning the secondary instrument panel between the front and rear seats of the vehicle, and in the central tunnel area, thereby facilitating use by the occupants.

[0037] Meanwhile, in some exemplary embodiments, the housing 100 of the auxiliary instrument in this embodiment includes a second housing 102 and a first housing 101 arranged vertically. The first housing 101 can be used to place items or in-vehicle devices such as a tea table 200. A cover plate 400 and a cover plate driving mechanism 500 are disposed on the second housing 102, and will not be described further below.

[0038] It should be noted that the direction-related descriptions in this embodiment are merely illustrative examples. In actual implementation, the direction descriptions in this embodiment will vary depending on the setting direction of the auxiliary instrument; that is, the directions in this embodiment refer to a relative coordinate system with the auxiliary instrument as the reference.

[0039] Combination Figures 2 to 6As shown, in some exemplary embodiments, a guide slide is integrated on the inner wall of the housing 100, and a sliding portion is provided on the cover plate 400, which slidably engages with the guide slide. The guide slide is configured to guide the cover plate 400 to move between a first position and a second position. In the first position, the cover plate 400 covers the top of the housing 100, forming a closed state. In the second position, the cover plate 400 can be completely retracted into the housing 100, forming a retracted state. Thus, the coordinated use of the guide slide and the sliding portion helps to improve the smoothness of the movement of the cover plate 400.

[0040] Meanwhile, in some exemplary embodiments, in the second position, the cover plate 400 of this embodiment is completely housed within one side of the housing 100. This allows for maximizing the capacity of the housing 100 and improving space utilization.

[0041] Furthermore, in some exemplary embodiments, the cover plate 400 of this embodiment includes a first cover plate 401 and a second cover plate 402. The sliding part includes a first sliding unit 4011 and a second sliding unit 4012 disposed on the first cover plate 401, and a third sliding unit 4021 and a fourth sliding unit 4022 disposed on the second cover plate 402. A connecting rod 403 is provided between the second sliding unit 4012 and the third sliding unit 4021. One end of the connecting rod 403 is hinged to the second sliding unit 4012, and the other end of the connecting rod 403 is hinged to the third sliding unit 4021.

[0042] Furthermore, the guide slide includes a first sub-guide slide 1021, a second sub-guide slide 1022, and a third sub-guide slide 1023 arranged sequentially. The first sliding unit 4011 is slidably disposed in the first sub-guide slide 1021, the second sliding unit 4012 and the third sliding unit 4021 are both slidably disposed in the second sub-guide slide 1022, and the fourth sliding unit 4022 is slidably disposed in the third sub-guide slide 1023.

[0043] It is understandable that by configuring the cover plate 400 to include a first cover plate 401 and a second cover plate 402, and based on the cooperative configuration of the first sliding unit 4011, the second sliding unit 4012, the third sliding unit 4021, the fourth sliding unit 4022 and the connecting rod 403, as well as the first sub-guide slide 1021, the second sub-guide slide 1022 and the third sub-guide slide 1023, it is possible to completely house the cover plate 400 in the housing 100.

[0044] Combination Figures 2 to 8 As shown, in some exemplary embodiments, the cover plate drive mechanism 500 drives the first cover plate 401 and the second cover plate 402 to move synchronously via a cable 503, and the housing 100 is provided with a pulley group 504 for supporting and guiding the cable 503.

[0045] Here, the cover plate 400 is driven by a combination of cable 503 and pulley block 504. Compared with the existing scheme of using linkage assembly and drive wheel to drive the cover plate, this not only achieves the purpose of driving the cover plate 400 smoothly, but also makes the structure simpler, occupies less space, and has a lower cost.

[0046] In specific implementations, in some exemplary embodiments, the cable 503 of this embodiment is wound around the pulley block 504, and the cover plate drive mechanism 500 is connected to the first cover plate 401 and the second cover plate 402 via the cable 503. Meanwhile, to prevent interference between the cable 503 and the sliding part, the pulley block 504 includes multiple fixed pulleys disposed in the housing, with the fixed pulleys arranged corresponding to the outer periphery to which the slide is to be reached, and the cable 503 is wound sequentially around each fixed pulley.

[0047] The pulley block 504 includes at least three fixed pulleys. By changing the arrangement of each fixed pulley, the direction of the tension force on the cable 503 can be realized, which is conducive to realizing the preset drive path of the cover plate 400. That is, it is conducive to realizing the complete storage of the cover plate 400 in one side of the housing 100. At the same time, the use of fixed pulleys can also ensure the stability of force transmission.

[0048] In detail, the first sliding unit 4011, the second sliding unit 4012, the third sliding unit 4021, and the fourth sliding unit 4022 of this embodiment all include a support leg and a sliding wheel disposed on the support leg. That is, the sliding wheel in the first sliding unit 4011 is slidably disposed in the first sub-guide slide 1021, the sliding wheels in the second sliding unit 4012 and the third sliding unit 4021 are both slidably disposed in the second sub-guide slide 1022, and the sliding wheel in the fourth sliding unit 4022 is slidably disposed in the third sub-guide slide 1023. The cable 503 is connected to the support leg of the first sliding unit 4011. That is, the cable 503 drives the first cover plate 401 to move through the first sliding unit 4011, thereby driving the entire cover plate 400 to move.

[0049] Furthermore, to ensure that the second cover plate 402 and the first cover plate 401 are sequentially housed in the housing 100, the guide slide in this embodiment, as shown... Figure 5As shown, the first sub-guide slide 1021, the second sub-guide slide 1022, and the third sub-guide slide 1023 are arranged vertically. The first sub-guide slide 1021 is an inclined straight line. The upper half of the second sub-guide slide 1022 is parallel to and close to the first sub-guide slide 1021, while the lower half of the second sub-guide slide 1022 gradually slopes downward. The third sub-guide slide 1023 has a first section, a second section, a third section, and a fourth section arranged sequentially. The first section gradually slopes forward from top to bottom, the second section is horizontal, the third section gradually slopes forward from top to bottom, and the fourth section extends downward from the end of the third section while gradually slopes backward.

[0050] Furthermore, in specific implementations, in some exemplary embodiments, the plurality of fixed pulleys includes a first fixed pulley 5041, a second fixed pulley 5042, a third fixed pulley 5043, a fourth fixed pulley 5044, a fifth fixed pulley 5045, and a sixth fixed pulley 5046. Among them, the first fixed pulley 5041 is located at the rear end of the first sub-guide slide 1021, the second fixed pulley 5042 is located at the front end of the first sub-guide slide 1021, the third fixed pulley 5043 is located behind the rear ends of the second sub-guide slide 1022 and the third sub-guide slide 1023, the fourth fixed pulley 5044 is located in front of the front end of the second sub-guide slide 1022, the fifth fixed pulley 5045 is located behind the bottom of the third section of the third sub-guide slide 1023, and the sixth fixed pulley 5046 is located in front of the fourth section of the third sub-guide slide 1023. In this way, multiple fixed pulleys are arranged around the periphery of the guide slide to avoid interference between the cable 503 and the cover plate 400 during sliding.

[0051] In addition, in some exemplary embodiments, the cover plate driving mechanism 500 of this embodiment includes a drive motor 501 and a drive wheel 502 disposed on the drive shaft of the drive motor 501, with one end of the cable 503 wound around the drive wheel 502. The main advantage of this arrangement is that it enables smooth driving of the cable 503, reduces friction and wear, and thus helps to reduce the failure rate.

[0052] The drive motor 501 can be an electric motor, and the drive wheel 502 can be the traction wheel of the traction cable 503. Of course, to ensure the stability of the movement of the cover plate 400, in this embodiment, the sliding part, guide slide, cable 503 and pulley block 504 can be arranged on opposite sides. For example, guide slides and pulley blocks 504 are provided on the inner sidewalls of both sides of the housing 100 along the width direction of the housing 100. The sliding part is adapted to the guide slide, the cable 503 is adapted to the pulley block 504, and the drive wheel 502 is adapted to the cable 503, etc.

[0053] Meanwhile, in some exemplary embodiments, in this embodiment, the top of the housing 100 is provided with an electromagnetic locking mechanism 600. When the cover plate 400 moves to the first position, the electromagnetic locking mechanism 600 is triggered, which can lock and fix the cover plate 400 to the top of the housing 100, so as to lock the cover plate 400 on the top of the housing 100, prevent the cover plate 400 from being accidentally opened due to pressing, and improve the reliability of the cover.

[0054] In some exemplary embodiments, the electromagnetic locking mechanism 600 includes an electromagnet assembly 601 disposed on the housing 100 and a locking tongue 602 driven by the electromagnet assembly 601. When the cover plate 400 reaches a first position, the electromagnet assembly 601 is energized and activated to drive the locking tongue 602 to extend and abut against the cover plate 400 to lock the cover plate 400. It is understood that the electromagnetic locking mechanism 600, including the electromagnet assembly 601 and the locking tongue 602, results in a simple structure and higher operational reliability.

[0055] Of course, in the specific implementation of this embodiment, the locking tongue 602 is made of a metal material that can magnetically engage with the electromagnet assembly 601. Meanwhile, in addition to the electromagnet assembly 601 and the locking tongue 602, the electromagnetic locking mechanism 600 can also employ other locking mechanisms, such as a cylinder. The locking tongue 602 can be the cylinder rod of the cylinder, or a locking rod connected to the cylinder rod. Preferably, the housing 100 is provided with a locking mounting groove 1024 for mounting the electromagnetic locking mechanism 600.

[0056] It is worth noting that, regarding the cover plate assembly of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 8 As shown, it includes, for example, a cover plate 400 disposed on the housing 100 of the auxiliary instrument, and a cover plate drive mechanism 500 and a cover plate transmission mechanism disposed in the housing 100.

[0057] The cover plate transmission mechanism includes a pulley block 504 and a cable 503 wound around the pulley block 504. The cover plate drive mechanism 500 is connected to the cover plate 400 via the cable 503. Furthermore, under the drive of the cover plate drive mechanism 500, the cover plate 400 can be switched to a first position covering the top of the housing 100, or retracted to a second position inside the housing 100.

[0058] The inner wall of the housing 100 is integrated with a guide slide, and the cover plate 400 is provided with a sliding part, which slides in conjunction with the guide slide. The guide slide is configured to guide the cover plate 400 to move between a first position and a second position.

[0059] In the second position, the cover plate 400 is completely housed within one side of the housing 100.

[0060] The cover plate 400 includes a first cover plate 401 and a second cover plate 402. The sliding part includes a first sliding unit 4011 and a second sliding unit 4012 disposed on the first cover plate 401, and a third sliding unit 4021 and a fourth sliding unit 4022 disposed on the second cover plate 402. The guide slide includes a first sub-guide slide 1021, a second sub-guide slide 1022 and a third sub-guide slide 1023 arranged sequentially. Furthermore, the first sliding unit 4011 is slidably disposed in the first sub-guide slide 1021, the second sliding unit 4012 and the third sliding unit 4021 are both slidably disposed in the second sub-guide slide 1022, the fourth sliding unit 4022 is slidably disposed in the third sub-guide slide 1023, and a connecting rod 403 is provided between the second sliding unit 4012 and the third sliding unit 4021. One end of the connecting rod 403 is hinged to the second sliding unit 4012, and the other end of the connecting rod 403 is hinged to the third sliding unit 4021.

[0061] The pulley block 504 includes at least three fixed pulleys disposed in the housing 100, and the cable 503 is wound around each fixed pulley in sequence.

[0062] The cover plate drive mechanism 500 includes a drive motor 501 and a drive wheel 502 mounted on the drive shaft of the drive motor 501, with one end of a cable 503 wound around the drive wheel 502.

[0063] The top of the housing 100 is provided with an electromagnetic locking mechanism 600. Specifically, when the cover plate 400 moves to the first position, the electromagnetic locking mechanism 600 is triggered, which can fix the cover plate 400 to the top of the housing 100.

[0064] The electromagnetic locking mechanism 600 includes an electromagnet assembly 601 disposed on the housing 100 and a locking tongue 602 driven by the electromagnet assembly 601. When the cover plate 400 reaches the first position, the electromagnet assembly 601 is energized and activated to drive the locking tongue 602 to extend and lock the cover plate (400).

[0065] In the above preferred embodiments, the specific configuration and arrangement of the housing 100, cover plate 400, cover plate driving mechanism 500, guide slide, sliding part, electromagnetic locking mechanism 600, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the housing 100, cover plate 400, cover plate driving mechanism 500, guide slide, sliding part, electromagnetic locking mechanism 600, etc. can also be referred to the descriptions in the above exemplary embodiments.

[0066] The cover plate assembly of this embodiment adopts the above design, which not only facilitates the electric drive of the cover plate 400 and enhances the technological and ceremonial feel of the auxiliary instrument, but also the cable 503 has flexible buffering characteristics, which can absorb the impact and vibration during the driving process and reduce noise. At the same time, the simple structure can also help reduce the space occupied in the housing 100, improve space utilization, and facilitate cost reduction design. Thus, the cover plate assembly has a better performance.

[0067] An embodiment of the second aspect of this application provides a secondary instrument panel disposed on a vehicle, wherein the housing 100 of the secondary instrument panel is provided with the cover assembly as described above.

[0068] Continue to combine Figure 1 and Figure 5 As shown, in some exemplary embodiments, the housing 100 includes a liftable tea table 200, which is specifically disposed within the first housing 101. When the tea table 200 is lowered into the housing 100, the cover plate 400 can enter a first position, and when the cover plate 100 is in a second position, the tea table 200 can be raised from the housing 100.

[0069] The tea table 200 is height-adjustable. When the cover 400 is opened, the tea table 200 can be raised to a position suitable for user use. After the tea table 200 is lowered into the housing 100, the cover 400 can cover and hide the tea table 200, which improves the safety of using the tea table 200 while driving, makes better use of the interior space, and allows the tea table 200 to better integrate into the cabin environment, enhancing the technological and ceremonial feel of the instrument panel.

[0070] In specific implementation, the housing 100 of this embodiment is provided with a tea table driving mechanism 2041 for driving the tea table 200 to rise and fall. When the tea table driving mechanism 2041 drives the tea table 200 to descend to a preset position, the cover plate driving mechanism 500 drives the cover plate 400 to move to the top of the housing 100 and seal the housing 100. When the cover plate driving mechanism 500 drives the cover plate 400 to be stored inside the housing 100, the tea table driving mechanism 2041 drives the tea table 200 to rise to the use position.

[0071] Furthermore, as mentioned above, the cover plate 400 of this embodiment can be completely stored in one side of the housing 100. Compared with the existing solution where the cover plate is partially exposed when stored in one side, the tea table 200 can be directly raised to the top of the housing 100 and cooperate with the annular frame 104 on the top of the housing 100 to eliminate the gap between the edge of the tea table 200 and the housing 100, thereby enhancing the exquisite feel of the tea table 200 when in use.

[0072] In some exemplary embodiments, the tea table 200 is housed within the first housing 101 via a lifting mechanism 204, enabling the tea table 200 to be raised or lowered. Furthermore, the tea table 200 and the lifting mechanism 204 are arranged sequentially, one above the other.

[0073] In some of the exemplary implementations, combined with Figures 10 to 12 The lifting mechanism 204 shown above can adopt a structure commonly used by those skilled in the art. For example, it includes a first base 2042 and a second base 2043 disposed vertically spaced in the first housing 101, a transmission component 2044 disposed between the first base 2042 and the second base 2043, and the tea table driving mechanism 2041 disposed on the second base 2043. The tea table 200 is disposed on the first base 2042, the second base 2043 is fixedly connected to the first housing 101, the tea table driving mechanism 2041 is connected to the transmission component 2044, and when the tea table driving mechanism 2041 drives the transmission component 2044, the transmission component 2044 can drive the first base 2042 to rise and fall, thereby driving the tea table 200 to rise and fall.

[0074] In specific implementations, in some exemplary embodiments, the transmission assembly 2044 of this embodiment includes a first hinge rod 20441 and a second hinge rod 20442 that are hinged to each other. One end of the first hinge rod 20441 is hinged to the first base 2042, and the other end of the first hinge rod 20441 is slidably disposed on the second base 2043. One end of the second hinge rod 20442 is hinged to the second base 2043, and the other end of the second hinge rod 20442 is slidably disposed on the first base 2042.

[0075] Meanwhile, the tea table drive mechanism 2041 includes a drive motor mounted on the second base 2043, a screw 2045 connected to the drive shaft of the drive motor, and a moving component 2046 connected to the screw 2045. The movable component 2046 includes a connecting block 20461 threadedly connected to the screw 2045, and a sliding rod 20462 disposed on the connecting block 20461. The sliding rod 20462 is hinged to the first hinge rod 20441. Both ends of the sliding rod 20462 are slidably disposed on the second base 2043. The axial direction of the screw 2045 is parallel to the sliding direction of the first hinge rod 20441 and the second hinge rod 20442. Thus, the screw 2045 can be driven to rotate by the drive motor, so that the screw 2045 drives the connecting block 20461 to slide along the axial direction of the screw 2045. In this way, the first base 2042 can be raised and lowered with the cooperation of the transmission component 2044, that is, the tea table 200 can be raised and lowered.

[0076] In some exemplary embodiments, the second base 2043 of this embodiment is provided with two second guide rails 20431 arranged opposite to each other along the width direction of the second base 2043. The two ends of the sliding rod 20462 slide in the two second guide rails 20431 respectively through the guide slider 20463, so as to improve the lifting stability of the first base 2042.

[0077] Similarly, in some exemplary embodiments, the second hinge rod 20442 can be slidably mounted on the first base 2042 via a support rod. The first base 2042 is provided with two first guide rails 20421 arranged opposite to each other along the width direction of the first base 2042. The two ends of the support rod slide in the two first guide rails 20421 respectively via guide sliders 20463, thereby improving the stability of the lifting and lowering of the first base 2042.

[0078] Furthermore, in order to further improve the stability of the lifting of the first base 2042, in some exemplary embodiments, a guide component is provided between the first housing 101 and the first base 2042 in this embodiment. The guide component includes a lifting guide rail provided on the first housing 101 and a lifting slider 20422 provided on the first base 2042, and the lifting slider 20422 is slidably provided on the lifting guide rail.

[0079] Of course, in the specific implementation of this embodiment, the number and arrangement of the guide components can be set and adjusted according to the lifting requirements of the tea table 200. For example, guide components are provided at both ends of the length direction of the first base 2042 to improve the stability of the lifting of the first base 2042.

[0080] Meanwhile, in this embodiment, to further ensure the stability of the lifting and lowering of the first base 2042, the number and arrangement of the first hinge rod 20441 and the second hinge rod 20442 in the transmission assembly 2044 can be adjusted accordingly. For example, the first hinge rod 20441 and the second hinge rod 20442 are two sets arranged opposite to each other along the width direction of the first base 2042, and the two sets of first hinge rods 20441 are connected by a sliding rod 20462, and the two sets of second hinge rods 20442 are connected by a support rod, etc.

[0081] In this embodiment, the auxiliary instrument, by setting the above-mentioned cover plate assembly, can improve space utilization and reduce costs. Moreover, the cover plate assembly has low noise during movement and has good performance.
