Description

Technical Field

[0001] This utility model relates to the field of carrier accessories, specifically to a ceiling screen installation structure, a ceiling screen bracket, and a carrier. Background Technology

[0002] When a vehicle travels on different road surfaces, the varying roughness of the road surface causes unique vibration transmission issues within the vehicle body. For example, on smooth surfaces like asphalt, although the high-frequency resonance between the tires and the road surface is relatively weak, the pumping effect of the tire tread pattern at high speeds still transmits vibrations caused by minor road unevenness to the vehicle body through the suspension system. On rough surfaces, such as gravel roads or damaged roads, the uneven geometric features directly excite large-amplitude radial vibrations in the tires. These low-frequency, high-amplitude mechanical vibrations are transmitted undiminished to the vehicle chassis structure through rigid components of the suspension system, such as shock absorbers and spring supports.

[0003] When the aforementioned vibrational energy is transmitted to the vehicle body, it excites modal resonance in the thin-walled structure of the vehicle body, generating low-frequency noise. This type of noise has significant sound pressure level superposition characteristics, forming a standing wave effect in the enclosed space of the vehicle, causing passengers to experience a noticeable pressure sensation in their ears, the so-called "low-frequency ear pressure phenomenon," which can lead to problems such as driver distraction and motion sickness among passengers.

[0004] In related technologies, additional vibration absorbers are usually added to the vehicle body to improve low-frequency noise generated inside the vehicle. For example, elastic buffer components and counterweights are set on the crossbeams at the top of the vehicle body. The counterweights are connected to the crossbeams through the elastic buffer components. As elastic oscillators, the counterweights can effectively counteract the vibrations generated at the crossbeam positions.

[0005] However, this method of using additional shock absorbers results in a complex interior structure, which is not conducive to the optimization of interior space design and the lightweight design of the vehicle body. Utility Model Content

[0006] This utility model provides a ceiling-mounted screen installation structure, ceiling-mounted screen bracket and carrier to solve or improve the problems of complex vehicle interior structure, unfavorable to vehicle interior space optimization design and vehicle body lightweight design caused by the additional setting of vibration absorbers in related technologies.

[0007] The first aspect of this utility model provides a ceiling-mounted screen installation structure, including a roof assembly and a ceiling-mounted screen assembly;

[0008] The ceiling-mounted screen assembly is connected to the roof assembly via an elastic connection structure, which is capable of elastic deformation in the same direction as the gravity of the ceiling-mounted screen assembly.

[0009] Beneficial effects:

[0010] In this solution, the ceiling-mounted screen assembly is connected to the roof assembly via an elastic connection structure. This configuration allows the ceiling-mounted screen assembly to function as an elastic oscillator for vibration absorption. When vibrations generated by vehicles such as cars, trains, and aircraft are transmitted to the roof, the ceiling-mounted screen assembly on the roof assembly can generate elastic vibrations, thereby counteracting the vibrations generated by the roof assembly and achieving the effect of a vibration absorber. Because this solution uses the ceiling-mounted screen assembly as the elastic oscillator for vibration absorption, there is no need to set up an additional elastic oscillator. This solves or improves the problems in related technologies where additional vibration absorbers lead to complex interior structures, hinder interior space optimization design, and impede lightweight vehicle design.

[0011] According to the ceiling-mounted screen installation structure provided by this utility model, the roof assembly includes a crossbeam;

[0012] The ceiling-mounted screen assembly includes a ceiling-mounted screen body and a support frame, wherein the ceiling-mounted screen body is connected to the support frame;

[0013] The bracket is connected to the crossbeam via the elastic connection structure.

[0014] Beneficial effects:

[0015] The crossbeam is a crucial component of the roof structure, possessing high strength and stability. The bracket connects to the crossbeam, reliably securing the ceiling-mounted screen assembly to the roof, ensuring it won't fall due to shaking or vibration during vehicle operation, providing a stable installation foundation. Utilizing the crossbeam as the mounting base for the ceiling-mounted screen assembly makes efficient use of roof space, avoiding the need for separate installation structures in other locations within the vehicle and thus optimizing the interior space layout. The bracket, acting as the connecting intermediary between the ceiling-mounted screen assembly and the crossbeam, facilitates easier installation and removal of the ceiling-mounted screen. The bracket connects to the crossbeam via an elastic connection structure, allowing the ceiling-mounted screen assembly to function as an elastic vibrator. When the vehicle vibrates during travel, the elastic connection structure allows the ceiling-mounted screen assembly to vibrate elastically within a certain range, effectively absorbing and counteracting vibrations from the crossbeam, thus providing a degree of vibration damping and noise reduction, and improving passenger comfort.

[0016] According to the ceiling screen installation structure provided by this utility model, the crossbeam and the bracket are provided with corresponding connection holes;

[0017] The elastic connection structure includes a connector and an elastic element, with both ends of the connector connected to the connection hole of the crossbeam and the connection hole of the bracket, respectively.

[0018] The elastic element is disposed between the connecting hole of the connector and the crossbeam, and / or the elastic element is disposed between the connecting hole of the connector and the bracket.

[0019] Beneficial effects:

[0020] The crossbeam and bracket have corresponding connection holes. When connecting the ceiling screen assembly to the crossbeam, the connectors are simply inserted into the corresponding connection holes, facilitating installation and improving efficiency. The elastic element in the flexible connection structure is located between the connector and the crossbeam's connection hole and / or between the connector and the bracket's connection hole. During vehicle operation, vibrations are transmitted to the vehicle body, causing the ceiling screen assembly to vibrate up and down. Because the elastic element is located between the connector and the connection hole, it undergoes reciprocating deformation under the force of the ceiling screen assembly, acting as an elastic oscillator to absorb the vehicle body's vibrations. Furthermore, since the elastic element is located between the connector and the connection hole, it can compensate for installation errors between the connector and the connection hole through its own deformation, ensuring smooth installation and stability of the ceiling screen assembly after installation. Simultaneously, during use, temperature changes and other factors may cause thermal expansion and contraction of the crossbeam or bracket; the elastic element adapts well to this deformation, preventing structural damage due to stress concentration.

[0021] According to the ceiling screen installation structure provided by this utility model, the elastic element includes an elastic ring, the outer ring surface of the elastic ring is connected to the inner wall of the connecting hole, and the connecting member extends into the inner ring of the elastic ring and is connected to the elastic ring.

[0022] Beneficial effects:

[0023] In this design, the elastic ring can be a ring-shaped structure made of a material with a certain degree of elasticity, such as rubber or silicone. The elastic ring is fitted inside the connecting hole, and its outer ring surface is connected to the inner wall of the connecting hole. The connector extends into the inner ring of the elastic ring and connects to it. When the elastic ring is positioned within the connecting hole of the bracket, if the ceiling-mounted screen assembly experiences displacement in the direction of gravity, a relative movement in the direction of gravity will occur between the bracket and the connector. At this time, the elastic ring between the bracket and the connector will undergo elastic deformation in the direction of gravity, thereby enabling the ceiling-mounted screen assembly to achieve the effect of an elastic oscillator. Simultaneously, the elastic ring can buffer the ceiling-mounted screen when subjected to vibration or impact, reducing potential component damage or screen shaking caused by vibration, and improving the stability and reliability of the ceiling-mounted screen installation. The connector can also be easily inserted into and connected to the inner ring of the elastic ring, allowing for quick positioning and fixation during installation. When the bracket or beam shifts or deforms due to thermal expansion and contraction or minor changes in the installation environment, the elastic ring can adapt to these changes through its own elastic deformation, avoiding structural damage or loosening caused by rigid connections, and ensuring that the ceiling screen always maintains a good installation condition.

[0024] According to the ceiling screen installation structure provided by this utility model, the elastic ring is connected to the inner wall of the connecting hole through a vulcanization process.

[0025] Beneficial effects:

[0026] The vulcanization process bonds the elastic ring to the inner wall of the connection hole. This connection method is more secure than ordinary physical connections (such as snap-fit ​​and adhesive), which can effectively prevent the elastic ring from loosening and falling off during long-term use and ensure the stability of the ceiling screen installation structure.

[0027] The ceiling-mounted screen installation structure provided by this utility model also includes a rigid ring, the outer ring surface of which is connected to the inner ring surface of the elastic ring, and the connector extends into the inner ring of the rigid ring and is connected to the rigid ring.

[0028] Beneficial effects:

[0029] The introduction of the rigid ring creates a composite structure of "rigid support + elastic buffer" between the connecting hole and the connector. As the primary load-bearing component, the rigid ring's rigid material can directly withstand the installation load of the connectors (such as bolts and clips) and the weight of the ceiling screen, preventing the elastic ring from undergoing plastic deformation or fatigue fracture due to long-term load-bearing. This improves the overall load capacity and deformation resistance of the structure. The elastic ring can also be connected to the outer ring of the rigid ring through a vulcanization process, preserving its elastic properties and allowing the ceiling screen assembly to be used as an elastic oscillator.

[0030] The second aspect of this utility model provides a ceiling screen bracket, including a bracket body, wherein the bracket body is provided with a plurality of connecting holes, and elastic rings are provided in the connecting holes.

[0031] Beneficial effects:

[0032] In this solution, the ceiling-mounted screen body is connected to the ceiling-mounted screen bracket, which is then installed onto the crossbeam. Because the bracket body has elastic rings inside the connection holes, the bracket body can be fixed to the vehicle body's crossbeam by inserting connectors into the connection holes. The elastic rings are located between the connectors and the connection holes, thus forming an elastic connection structure between the ceiling-mounted screen assembly (consisting of the ceiling-mounted screen body and the ceiling-mounted screen bracket) and the connectors. When the vehicle vibrates during travel, the ceiling-mounted screen assembly acts as an elastic oscillator, thus buffering vibrations on the vehicle body. This solves or improves the problems of complex interior structures, unfavorable interior space optimization design, and lightweight vehicle body design caused by additional vibration absorbers in related technologies.

[0033] According to the ceiling screen bracket provided by this utility model, a rigid ring is provided inside the elastic ring.

[0034] According to the ceiling screen bracket provided by this utility model, the elastic ring, the connecting hole, and the rigid ring are connected by a vulcanization process.

[0035] The third aspect of this utility model provides a carrier, including the ceiling screen mounting structure or the ceiling screen bracket described in any of the above claims.

[0036] Beneficial effects:

[0037] The vehicle provided by this utility model, having the aforementioned ceiling-mounted screen mounting structure or ceiling-mounted screen bracket, can solve or improve the problems in related technologies caused by the additional installation of vibration absorbers, such as complex vehicle interior structure, unfavorable interior space optimization design, and lightweight vehicle body design. The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effects brought by the aforementioned ceiling-mounted screen mounting structure or ceiling-mounted screen bracket, and will not be repeated here.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] In related technologies, vibration absorbers are typically installed on the vehicle body to reduce or improve low-frequency noise generated inside the vehicle during operation. The vibration absorber includes an elastic buffer component and a counterweight. The counterweight is connected to the vehicle body via the elastic buffer component and acts as an elastic oscillator, effectively counteracting vibrations generated at the crossbeam location. However, this method of using additional vibration absorbers results in a complex interior structure, which is detrimental to the optimized design of the interior space and the lightweight design of the vehicle body.

[0046] In view of this, the present invention provides a ceiling-mounted screen installation structure, a ceiling-mounted screen bracket and a carrier, to solve or improve the problems in the related art caused by the additional setting of vibration absorbers, which leads to complex vehicle interior structure, is not conducive to the optimization design of vehicle interior space and the lightweight design of vehicle body.

[0047] like Figures 1 to 3 As shown, the ceiling-mounted screen installation structure provided in this embodiment of the present invention includes a roof assembly and a ceiling-mounted screen assembly. In some embodiments, the roof assembly may include a crossbeam 12, longitudinal beams, a sunroof or canopy, etc., and the ceiling-mounted screen assembly is installed on the roof assembly, specifically, on the crossbeam 12. Of course, in other embodiments, it may also be installed on the longitudinal beam or other locations.

[0048] In this design, the ceiling-mounted screen assembly is connected to the roof assembly via an elastic connection structure. This elastic connection structure is capable of elastic deformation aligned with the direction of gravity of the ceiling-mounted screen assembly. In other words, under the influence of the elastic connection structure, the ceiling-mounted screen assembly can generate elastic reciprocating motion in the direction of gravity.

[0049] In this embodiment, the ceiling-mounted screen assembly is connected to the roof assembly via an elastic connection structure. This configuration allows the ceiling-mounted screen assembly to function as an elastic oscillator for vibration absorption. When vibrations generated by vehicles such as cars, trains, and aircraft during operation are transmitted to the roof, the ceiling-mounted screen assembly on the roof assembly can generate elastic vibrations, thereby counteracting the vibrations generated by the roof assembly and achieving the effect of a vibration absorber. Because this solution uses the ceiling-mounted screen assembly as the elastic oscillator for vibration absorption, there is no need to set up an additional elastic oscillator. This solves or improves the problems in related technologies where additional vibration absorbers lead to complex interior structures, hinder interior space optimization design, and impede lightweight vehicle design.

[0050] In a further embodiment, the ceiling-mounted screen assembly includes a ceiling-mounted screen body (not shown) and a bracket 11, the ceiling-mounted screen body being connected to the bracket 11. The bracket 11 is connected to the crossbeam 12 via an elastic connection structure. In some embodiments, the bracket 11 may be made of metal, and the ceiling-mounted screen body is fixed to the bracket 11 by screws, clips, or other components.

[0051] It should be understood that the crossbeam 12 is an important component of the roof structure, possessing high strength and stability. The bracket 11 connects to the crossbeam 12, reliably fixing the ceiling screen assembly to the roof and ensuring that the ceiling screen will not fall off due to shaking or vibration during vehicle operation, thus providing a stable installation foundation for the ceiling screen.

[0052] Using the crossbeam 12 as the mounting base for the ceiling-mounted screen component makes reasonable use of the roof space and avoids occupying extra space by setting up separate installation structures in other locations inside the vehicle, which is conducive to optimizing the interior space layout.

[0053] The bracket 11 serves as a connecting intermediary between the ceiling-mounted screen assembly and the crossbeam 12, making the installation and removal of the ceiling-mounted screen more convenient. The bracket 11 is connected to the crossbeam 12 via an elastic connection structure, allowing the ceiling-mounted screen assembly to function as an elastic oscillator. When the vehicle vibrates during operation, the elastic connection structure allows the ceiling-mounted screen assembly to vibrate elastically within a certain range, effectively absorbing and offsetting vibrations from the crossbeam 12, thus achieving a certain degree of vibration damping and noise reduction, and improving the ride comfort inside the vehicle.

[0054] In a further embodiment, the crossbeam 12 and the bracket 11 are provided with corresponding connecting holes. The elastic connection structure includes a connector 13 and an elastic element 14. The two ends of the connector 13 are respectively connected to the connecting holes of the crossbeam 12 and the connecting holes 111 of the bracket. In some embodiments, the connector 13 may specifically be a bolt. The crossbeam 12 is provided with a boss 121, and the boss 121 is provided with a connecting hole. Specifically, the connecting hole on the boss 121 is a threaded hole.

[0055] It should be noted that the diameter of the bolt head 131 or the circumscribed circle diameter must be greater than the inner diameter of the elastic ring 141 and less than the outer diameter of the elastic ring 141.

[0056] When the bracket 11 is installed on the crossbeam 12, the threaded end of the bolt passes through the connecting hole 111 of the bracket and forms a threaded connection with the connecting hole of the crossbeam 12. The head 131 of the bolt abuts against the end of the elastic ring 141, thereby realizing the connection between the bracket 11 and the crossbeam 12.

[0057] Of course, in other embodiments, the connector 13 can also be of other types, such as a buckle with a barbed structure. The buckle has a rod, one end of which has an end cap. The diameter of the end cap is larger than the diameter of the connecting hole 111 of the bracket, and a barbed structure is provided near the other end. When the bracket 11 and the crossbeam 12 are connected together by the buckle, the barbed end passes through the connecting hole 111 of the bracket and then connects with the connecting hole of the crossbeam 12.

[0058] The elastic element 14 is disposed between the connecting hole of the connector 13 and the crossbeam 12, and / or the elastic element 14 is disposed between the connecting hole 111 of the connector 13 and the bracket, thereby making the connection between the connector 13 and the crossbeam 12 form an elastic connection, and / or the connection between the connector 13 and the bracket 11 form an elastic connection.

[0059] In a preferred embodiment, the elastic element 14 is disposed between the connector 13 and the connecting hole 111 of the bracket. The elastic element 14 can be an elastic ring 141, which is connected to the connecting hole 111 of the connector 13 and the bracket respectively, thereby making the connector 13 and the bracket 11 elastically connected, that is, the connector 13 and the bracket 11 can form an elastic relative movement.

[0060] Of course, in other embodiments, the elastic element 14 is also provided between the connecting hole of the connector 13 and the crossbeam 12, or the above-mentioned elastic element 14 is provided between the connecting hole of the connector 13 and the crossbeam 12, and between the connecting hole 111 of the connector 13 and the bracket.

[0061] With this configuration, the elastic element 14 in the elastic connection structure is positioned between the connecting hole of the connector 13 and the crossbeam 12 and / or between the connecting hole 111 of the connector 13 and the bracket. When the vehicle is in motion, vibrations are transmitted to the vehicle body, and the ceiling-mounted screen assembly vibrates up and down with the vehicle body. Since the elastic element 14 is positioned between the connector 13 and the connecting hole, the elastic element 14 undergoes reciprocating deformation under the force of the ceiling-mounted screen assembly. The ceiling-mounted screen assembly acts as an elastic oscillator, thereby absorbing the vibrations of the vehicle body.

[0062] Furthermore, since the elastic element 14 is located between the connector 13 and the connecting hole, the elastic element 14 can compensate for the installation error between the connecting hole and the connector 13 through its own deformation, thereby ensuring that the ceiling screen assembly can be installed smoothly and remain stable after installation.

[0063] Meanwhile, during the use of the ceiling screen, factors such as temperature changes may cause thermal expansion and contraction of the crossbeam 12 or the bracket 11. The elastic element 14 can also adapt well to this deformation, avoiding structural damage caused by stress concentration.

[0064] In a further embodiment, the elastic member 14 includes an elastic ring 141, the outer ring surface of which is connected to the inner wall of the connecting hole, and the connecting member 13 extends into the inner ring of the elastic ring 141 and is connected to the elastic ring 141.

[0065] In this embodiment, the elastic ring 141 can be a ring-shaped structure made of a material with a certain elasticity, such as a rubber ring or a silicone ring. The elastic ring 141 is fitted inside the connecting hole, and the outer ring surface of the elastic ring 141 is connected to the inner wall surface of the connecting hole. The connector 13 extends into the inner ring of the elastic ring 141 and connects to the elastic ring 141. When the elastic ring 141 is set in the connecting hole 111 of the bracket, if the ceiling screen assembly generates a displacement in the direction of gravity, a relative movement in the direction of gravity will occur between the bracket 11 and the connector 13. At this time, the elastic ring 141 between the bracket 11 and the connector 13 will undergo elastic deformation in the direction of gravity, thereby enabling the ceiling screen assembly to achieve the effect of an elastic oscillator.

[0066] Meanwhile, the elastic ring 141 can buffer the ceiling screen when it is subjected to vibration or impact, reducing the damage to components or screen shaking that may be caused by vibration, and improving the stability and reliability of the ceiling screen installation.

[0067] The connector 13 can also be easily inserted into and connected to the inner ring of the elastic ring 141, allowing for quick positioning and fixation during installation. When the bracket 11 or crossbeam 12 shifts or deforms due to thermal expansion and contraction or minor changes in the installation environment, the elastic ring 141 can adapt to these changes through its own elastic deformation, avoiding structural damage or loosening caused by rigid connections, and ensuring that the ceiling screen always maintains a good installation condition.

[0068] In order to achieve a reliable connection between the elastic ring 141 and the connecting hole, in a preferred embodiment, the elastic ring 141 can be connected to the inner wall of the connecting hole through a vulcanization process.

[0069] The vulcanization process allows the elastic ring 141 to bond together with the inner wall of the connection hole. This connection method is more secure than ordinary physical connections (such as snap-fit ​​or adhesive bonding), which can effectively prevent the elastic ring 141 from loosening or falling off during long-term use and ensure the stability of the ceiling screen installation structure.

[0070] In other embodiments, the elastic ring 141 can also be connected to the connecting hole by snap-fitting, adhesive bonding, or other means.

[0071] In a further embodiment, the ceiling-mounted screen mounting structure also includes a rigid ring 15, the outer ring surface of which is connected to the inner ring surface of the elastic ring 141, and a connector 13 extends into the inner ring of the rigid ring 15 and is connected to the rigid ring 15. In some embodiments, the rigid ring 15 is made of materials such as iron, aluminum, or alloy.

[0072] The introduction of the rigid ring 15 makes the connection structure between the connecting hole and the connector 13 form a composite structure of "rigid support + elastic buffer". As the main load-bearing component, the rigid ring 15 can directly bear the installation load of the connector 13 (such as bolts and buckles) and the weight of the ceiling screen, avoiding the elastic ring 141 from plastic deformation or fatigue fracture due to long-term load, and improving the overall load limit and deformation resistance of the structure.

[0073] The elastic ring 141 can also be connected to the outer ring surface of the rigid ring 15 through a vulcanization process, which not only ensures the reliability of the connection between the rigid ring 15 and the elastic ring 141, but also retains the elastic properties of the elastic ring 141, so that the ceiling screen component can be used as an elastic vibrator.

[0074] An embodiment of this utility model also provides a ceiling screen bracket, including a bracket body with multiple connecting holes and elastic rings 141 disposed within the connecting holes. In some embodiments, the bracket body may have six connecting holes, which are symmetrically distributed on both sides of the bracket body to form a reliable connection with the crossbeam 12, and each connecting hole is provided with an elastic ring 141.

[0075] With this configuration, the ceiling-mounted screen body is connected to the ceiling-mounted screen bracket, and then installed onto the crossbeam 12 via the ceiling-mounted screen bracket. Since the bracket body provided in this solution has an elastic ring 141 inside the connection hole, the bracket body can be fixed to the crossbeam 12 of the vehicle body by inserting a connector 13 into the connection hole. The elastic ring 141 is located between the connector 13 and the connection hole, thus forming an elastic connection structure between the ceiling-mounted screen body and the ceiling-mounted screen bracket assembly and the connector 13. When the vehicle vibrates during travel, the ceiling-mounted screen assembly will act as an elastic oscillator, thereby buffering the vibrations on the vehicle body. This can solve or improve the problems of complex interior structure, unfavorable interior space optimization design, and lightweight vehicle body design caused by additional vibration absorbers in related technologies.

[0076] In a further embodiment, a rigid ring 15 is provided inside the elastic ring 141 of the ceiling-mounted screen bracket. The rigid ring 15 can be made of materials such as iron, aluminum, or alloy. Both the elastic ring 141 and the rigid ring 15 are ring-shaped structures. The rigid ring 15 is sleeved inside the elastic ring 141, and the elastic ring 141 is sleeved inside the connecting hole of the bracket body. The connecting hole, the elastic ring 141, and the rigid ring 15 form a reliable connection. In some embodiments, the elastic ring 141, the connecting hole, and the rigid ring 15 are connected by a vulcanization process.

[0077] When connecting the ceiling screen bracket to the crossbeam 12, bolts can be used as connectors 13. Specifically, the threaded end of the bolt passes through the rigid ring 15 of the ceiling screen bracket and is connected to the connecting hole of the crossbeam 12 via a threaded connection. It should be noted that the diameter of the bolt head 131 or the outer circle diameter needs to be greater than the inner diameter of the rigid ring 15 and smaller than the outer diameter of the elastic ring 141. Preferably, the diameter of the bolt head 131 or the outer circle diameter is equal to the inner diameter of the elastic ring 141.

[0078] When the ceiling screen bracket is installed onto the crossbeam 12, the threaded end of the bolt passes through the rigid ring 15 of the ceiling screen bracket and forms a threaded connection with the connecting hole of the crossbeam 12. The head 131 of the bolt abuts against the end of the rigid ring 15, thereby realizing the connection between the ceiling screen bracket and the crossbeam 12.

[0079] This utility model embodiment also provides a carrier, including the ceiling-mounted screen mounting structure or the ceiling-mounted screen bracket described in any of the above claims. In some embodiments, the carrier may be a vehicle, aircraft, construction machinery, etc.

[0080] The vehicle provided in this embodiment, having the ceiling-mounted screen mounting structure or ceiling-mounted screen bracket described in the above embodiments, can solve or improve the problems in related technologies caused by the additional installation of vibration absorbers, such as complex vehicle interior structure, unfavorable interior space optimization design, and lightweight vehicle body design. The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effects brought by the above-mentioned ceiling-mounted screen mounting structure or ceiling-mounted screen bracket, and will not be repeated here.
