Description

Technical Field

[0001] This utility model belongs to the technical field of car sound insulation, and in particular relates to a car wall module, a car, and an elevator. Background Technology

[0002] The elevator car, a crucial component, is a box-shaped space used to carry and transport people and goods. Typically, the car walls have ventilation circuits that facilitate the exchange of air between the inside and outside of the car.

[0003] Traditional elevator car wall structures are relatively simple and have poor sound insulation performance, failing to effectively block noise generated by motor operation and car movement, severely impacting passenger comfort. Currently, existing elevator cars address this issue by arranging sound-absorbing cotton within the ventilation circuits inside the car walls to reduce noise. However, during continuous operation, the airflow within the ventilation circuits causes long-term erosion and scouring of the sound-absorbing cotton, leading to a decrease in its sound insulation performance and consequently affecting both sound insulation effectiveness and car comfort. Utility Model Content

[0004] In view of this, it is necessary to provide a car wall module, car and elevator that can effectively provide high sound insulation for a long time.

[0005] A car wall module, comprising:

[0006] Car wall panels;

[0007] The rear sealing plate is connected to the car wall panel and forms a cavity with the car wall panel. The cavity includes a sound insulation chamber and a ventilation chamber, and the ventilation chamber is located on the periphery of the sound insulation chamber.

[0008] A sound insulation pad is provided corresponding to the sound insulation chamber, and the sound insulation pad is provided in the area where the corresponding sound insulation chamber is located. Furthermore, the sound insulation pad is attached to the car wall panel and the rear sealing plate on both sides of the car wall module in the thickness direction.

[0009] The car wall panel has a first ventilation hole, and the rear sealing plate has a second ventilation hole. The second ventilation hole and the first ventilation hole are connected through the ventilation chamber.

[0010] Understandably, the sound insulation pad is pressed and limited to the car wall panel by the rear sealing plate, and the ventilation chamber around the sound insulation pad is used to provide ventilation for the car wall module. This ensures that the ventilation of the car wall module will not affect the assembly of the sound insulation pad, and reduces the contact area between the sound insulation pad and the air flowing in the ventilation chamber. This ensures the stability of the sound insulation pad assembly between the car wall panel and the rear sealing plate, and delays the aging time of the sound insulation pad, so that the car wall module can effectively provide a high level of sound insulation for a long time.

[0011] In one embodiment, the number of sound insulation pads is configured to be multiple, and the multiple sound insulation pads are arranged sequentially at intervals in the height direction of the car wall module;

[0012] The ventilation chamber includes a main ventilation path, which is located in the spacer between any two adjacent sound insulation pads. The second ventilation hole is located on the rear sealing plate at a position corresponding to the main ventilation path.

[0013] It is understandable that placing the second ventilation hole on the rear panel at the gap between two adjacent sound insulation pads allows the car wall module to have a sufficiently large area to accommodate the sound insulation pads, thereby further improving the sound insulation effect of the car wall module.

[0014] In one embodiment, the first ventilation hole is offset from the sound insulation pad in the height direction of the car wall module.

[0015] In one embodiment, the first ventilation hole is located above the sound insulation pad;

[0016] And / or, the first ventilation hole is located below the sound insulation pad.

[0017] In one embodiment, the sound insulation pad is glued to the car wall panel on one side of the car wall module in the thickness direction, and the sound insulation pad is pressed and limited against the rear sealing plate on the other side of the car wall module in the thickness direction.

[0018] It is understandable that, through the above structural design, the sound insulation pad can be first fixed to the car wall panel by adhesive. Then, when the rear sealing plate is assembled and fixed on the car wall panel, the sound insulation pad can be compacted by the rear sealing plate, which facilitates the assembly of the sound insulation pad in the car wall module.

[0019] In one embodiment, in the height direction of the car wall module, the top and bottom of the car wall panel are respectively sealed with end plates, the end plates are received in the cavity and abut against the rear end plate for sealing.

[0020] It is understandable that using end plates to cover the top and bottom of the car wall module can both reduce noise leakage and improve the aesthetics of the car wall module.

[0021] In one embodiment, the car wall panel has bent side plates formed on both sides of the car wall module in the width direction, and the bent free ends of the bent side plates on both sides extend towards each other. The rear sealing plate is attached to the two bent side plates and is connected to the two bent side plates respectively.

[0022] This application also provides a car, including a plurality of the car wall modules described above, wherein the plurality of car wall modules are connected in sequence to form a car wall.

[0023] In one embodiment, a sealing gasket is provided between any two adjacent car wall modules among the plurality of car wall modules.

[0024] It is understandable that a sealing gasket is placed between two adjacent car wall modules to further ensure the airtightness and sound insulation of the car.

[0025] This application also provides an elevator, including the car described above.

[0026] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0027] The car wall module, car, and elevator for which this application seeks protection use a rear sealing plate to press and limit the sound insulation pad to the car wall panel, and use the ventilation chamber around the sound insulation pad to provide ventilation for the car wall module. This ensures that the ventilation of the car wall module does not affect the assembly of the sound insulation pad, and reduces the contact area between the sound insulation pad and the air flowing in the ventilation chamber. This ensures the stability of the assembly of the sound insulation pad between the car wall panel and the rear sealing plate, and delays the aging time of the sound insulation pad, so that the car wall module can effectively provide a high level of sound insulation for a long time.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] like Figure 1 , Figure 2As shown, the car wall module 100 provided in this application includes a car wall panel 10, a rear sealing panel 20, and a sound insulation pad 30. The rear sealing panel 20 is connected to the car wall panel 10 and forms a cavity (not shown) with the car wall panel 10. The cavity includes a sound insulation chamber 111 and a ventilation chamber 112. The ventilation chamber 112 is disposed around the sound insulation chamber 111. The sound insulation pad 30 is disposed correspondingly to the sound insulation chamber 111 and is disposed in the area of ​​the corresponding sound insulation chamber 111. The sound insulation pad 30 is attached to the car wall panel 10 and the rear sealing panel 20 on both sides in the thickness direction X of the car wall module 100. The car wall panel 10 has a first ventilation hole 101 at the location of the ventilation chamber 112, and the rear sealing panel 20 has a second ventilation hole 102 at the location of the ventilation chamber 112. The second ventilation hole 102 and the first ventilation hole 101 are connected through the ventilation chamber 112. Here, the sound insulation pad 30 is placed in the area where the corresponding sound insulation chamber 111 is located, specifically, the sound insulation pad 30 fills the corresponding sound insulation chamber 111.

[0039] As can be seen from the above, the car wall module 100 of this application uses the rear sealing plate 20 to press and limit the sound insulation pad 30 onto the car wall panel 10, and uses the ventilation chamber 112 around the sound insulation pad 30 to provide ventilation for the car wall module 100. This ensures that the ventilation of the car wall module 100 will not affect the assembly of the sound insulation pad 30, and reduces the contact area between the sound insulation pad 30 and the airflow in the ventilation chamber 112. This ensures the stability of the assembly of the sound insulation pad 30 between the car wall panel 10 and the rear sealing plate 20, and delays the aging time of the sound insulation pad 30, so that the car wall module 100 can effectively provide a high sound insulation effect for a long time.

[0040] It should be noted that, since the ventilation chamber 112 for ventilation in the car wall module 100 of this application is located on the periphery of the sound insulation pad 30, the size of the sound insulation pad 30 in the car wall module 100 can be set as large as possible to fit the size of the car wall panel 10.

[0041] like Figure 1 , Figure 5 As shown, in one embodiment, the car wall panel 10 has bent side plates 11 formed on both sides in the width direction X of the car wall module 100. The bent free ends 110 of the two side plates 11 extend towards each other, that is, they both extend towards the inner center of the car wall panel 10. The rear sealing plate 20 is attached to the two bent side plates 11 and connected to them respectively. Specifically, the rear sealing plate 20 can be fastened to the two bent side plates 11 using bolts, screws or other connecting parts, which facilitates the assembly and connection of the rear sealing plate 20 on the car wall panel 10. It can be understood that in other embodiments, the rear sealing plate 20 and the bent side plates 11 can also be connected by adhesive, welding or other methods, or the bent side plate used to connect the car wall panel 10 and the rear sealing plate 20 can be set on the rear sealing plate 20. This will not be elaborated here.

[0042] like Figure 1 , Figure 2 As shown, in one embodiment, the sound insulation pad 30 is adhesively connected to the car wall panel 10 on one side of the car wall module 100 in the thickness direction X, and the sound insulation pad 30 is pressed and limited by the rear sealing plate 20 on the other side of the car wall module 100 in the thickness direction X. That is to say, when assembling the car wall module 100, the sound insulation pad 30 can be fixed to the car wall panel 10 by adhesive first. Then, when the rear sealing plate 20 is assembled and fixed on the car wall panel 10, the sound insulation pad 30 can be compacted by the rear sealing plate 20. That is, the assembly of the rear sealing plate 20 does not need to consider the presence of the sound insulation pad 30, which facilitates the assembly of the sound insulation pad 30 in the car wall module 100.

[0043] It should be noted that the car wall panel 10 in this application is the basic load-bearing structure in the car wall module 100. Specifically, it can be made of high-strength metal sheet, which has good rigidity and stability to withstand various stresses during the operation of the car 1000. Furthermore, the rear sealing plate 20 in this application can be made of lightweight and high-strength materials, such as aluminum alloy sheet, so that while the rear sealing plate 20 compacts the sound insulation pad 30, it can ensure the overall structural stability of the car wall module 100 and prevent the sound insulation pad 30 from shifting or falling off during long-term use.

[0044] In one embodiment, the sound insulation pad 30 is configured as polyester fiber sound-absorbing cotton. Utilizing the material properties of polyester fiber sound-absorbing cotton, it can effectively absorb sound at different frequencies, converting sound energy into heat energy. This further enhances the sound insulation effect of the car wall module 100. It is understood that in other embodiments, the sound insulation pad 30 may also be configured as rock wool, centrifugal glass wool, mineral wool, etc., which will not be elaborated upon here.

[0045] like Figure 1 , Figure 2As shown, in one embodiment, multiple sound insulation pads 30 are configured, and these pads 30 are arranged sequentially at intervals along the height direction Z of the car wall module 100. The ventilation chamber 112 includes a main ventilation path 1121, which is located in the space between any two adjacent sound insulation pads 30. A second ventilation hole 102 is located on the rear sealing plate 20 at a position corresponding to the main ventilation path 1121. In other words, the second ventilation hole 102 is located on the rear sealing plate 20 in the gap between two adjacent sound insulation pads 30, providing the car wall module 100 with a sufficiently large area to accommodate the sound insulation pads 30, thereby further improving the sound insulation effect of the car wall module 100. Here, two sound insulation pads 30 are configured. It is understood that in other embodiments, the number of sound insulation pads 30 may be three, four, or even more, which will not be elaborated upon here.

[0046] like Figure 1 , Figure 2 As shown, in one embodiment, the first ventilation hole 101 is staggered with the sound insulation pad 30 in the height direction Z of the car wall module 100. Here, the first ventilation hole 101 is located above the sound insulation pad 30; and / or, the first ventilation hole 101 is located below the sound insulation pad 30. That is, the car wall panel 10 has first ventilation holes 101 above and below the sound insulation pad 30 in the height direction Z of the car wall module 100, so that when the car wall module 100 is applied in the car 1000, the car 1000 can be vented from the top and bottom. This prevents the air vented from the first ventilation hole 101 from blowing directly onto the passengers in the car 1000, thereby improving the passengers' riding experience.

[0047] like Figure 1 , Figure 2 As shown, in one embodiment, in the height direction Z of the car wall module 100, the top and bottom of the car wall panel 10 are respectively sealed with end caps 40, which are housed in a cavity and abut against and seal with the rear end cap 20. That is, the end caps 40 not only shield the top and bottom of the car wall module 100 to improve its aesthetics but also reduce noise leakage. Here, the end caps 40 can be made of galvanized steel, and specifically, they can be attached to the car wall panel 10 by adhesive bonding. It should be noted that the portion of the cavity used to house the end caps 40 is separate from the sound insulation chamber 111 and the ventilation chamber 112.

[0048] In summary, during the assembly of the car wall module 100 of this application, the car wall panel 10 is first prepared, and its surface is cleaned and pre-treated to ensure that the adhesive can adhere the sound insulation pad 30 to the car wall panel 10. Next, the sound insulation pad 30 is cut to the specified dimensions, and adhesive is evenly applied to the corresponding mating surfaces of the sound insulation pad 30 and the car wall panel 10. The sound insulation pad 30 is then smoothly adhered to the car wall panel 10, ensuring no air bubbles or wrinkles. Then, the rear sealing plate 20 is placed on the sound insulation pad 30. According to the predetermined bolt installation positions, tools are used to pass the bolts through the bent edge plates 11 of the rear sealing plate 20 and the car wall panel 10, and the bolts are tightened to press the sound insulation pad 30 firmly against the rear sealing plate 20. Finally, the two end plates 40 are adhered to the top and bottom of the car wall panel 10, completing the individual assembly of the entire car wall module 100.

[0049] like Figure 3 , Figure 4 As shown, this application also provides a car 1000, including a plurality of car wall modules 100 as described above, which are connected to form a car wall 1100. Specifically, the connection between two adjacent car wall modules 100 can be achieved by connecting and fixing the bent side plates 11 that are attached to each other on two car wall panels 10 with bolts.

[0050] like Figure 5 As shown, in one embodiment, a sealing gasket 200 is respectively provided between any two adjacent car wall modules 100 in the plurality of car wall modules 100. The sealing gasket 200 is used to assemble and seal the two adjacent car wall modules 100, which can further ensure the airtightness and sound insulation effect of the car 1000. Here, the sealing gasket 200 can be a rubber gasket, silicone gasket, etc.

[0051] In addition, this application also provides an elevator, including the car 1000 described above.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
