Abstract
Description
Technical Field
[0001] This utility model relates to a cab heater mounting structure, belonging to the field of excavator technology. Background Technology
[0002] Most current cab heaters are installed in the seat bracket under the seat, or by making a large hole in the cab floor and placing the heater in the hole.
[0003] If the installation layout of the heater installed in the seat bracket under the seat is restricted, due to the limited installation space under the seat, it is often necessary to raise the height of the seat bracket or increase the width of the seat bracket to install the heater. Raising the seat bracket will inevitably lead to a decrease in seat comfort, and increasing the width of the bracket will also create the risk of interference.
[0004] If holes are made in the floor of the cab, there is a risk of reduced floor rigidity and strength. At the same time, the heater's air inlet and outlet and the air conditioner's foot blowing air often enter the cab through the seat bracket. This will not only cause the heater to obstruct the air conditioner's foot blowing air, but also reduce the air heating circulation efficiency because the heater's air inlet and outlet and the air conditioner's foot blowing air are in different directions.
[0005] Therefore, both of the above installation structures can easily obstruct the air conditioning from blowing air into the driver's cab. Summary of the Invention
[0006] To address the shortcomings of existing technologies, this utility model provides a cab heater installation structure that allows for sufficient space to install the heater and makes its arrangement more flexible, while the seat mounting bracket structure remains unchanged. This does not reduce seat comfort or the rigidity and strength of the floor, and it does not obstruct the air conditioning from blowing into the cab, thus improving the air heating circulation efficiency.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, a cab heater mounting structure includes a cab floor plate 6, a heater assembly 10, and a seat mounting bracket 2. The cab floor plate 6 has an air inlet 61 and an air outlet 62. The heater assembly 10 is installed on the lower part of the cab floor plate 6, with its air inlet connected to the air inlet 61 and its air outlet connected to the air outlet 62, forming a cab air heating circulation path. The seat mounting bracket 2 is installed on the upper part of the cab floor plate 6, serving two purposes: firstly, to mount the seat assembly 10, and secondly, to block the airflow between the air inlet 61 and the air outlet 62, preventing the air inlet 61 from drawing in the airflow discharged from the air outlet 62, thus further improving the air heating circulation efficiency. This invention allows for sufficient space to install the heater and makes its arrangement more flexible, while the seat mounting bracket structure remains unchanged, without reducing seat comfort or the rigidity and strength of the floor plate, and without obstructing the air conditioning's foot-blowing air from entering the cab, thus improving the air heating circulation efficiency.
[0027] It should be noted that the cab floor 6 is also equipped with a wiring hole 63.
[0028] Further options, such as Figure 1 , Figure 3 As shown, the cab floor plate 6 has an air intake duct 4 at the air intake 61 for guiding airflow, and an air outlet duct 3 at the air outlet 62 for guiding airflow. The outlet of the air outlet duct 3 faces the driver, so hot air will blow directly on the driver and will not obstruct the air conditioning from blowing into the cab.
[0029] Further options, such as Figure 3 As shown, a sealing sponge 13 is wrapped between the air outlet duct 3 and the air outlet of the heater assembly 10 to enhance the sealing effect between the air outlet duct 3 and the heater assembly 10.
[0030] The following provides a further explanation of the specific structure and installation method of the aforementioned seat mounting bracket.
[0031] Example 1: As Figure 1 , Figure 3As shown, the seat mounting bracket 2 is bolted to the cab floor plate 6. The seat mounting bracket 2 and the cab floor plate 6 form a mounting cavity. The seat mounting bracket 2 is only open on the side facing the driver. The air duct 3 is located in the mounting cavity, dividing the inner and outer space of the seat mounting bracket 2 into an air outlet cavity and an air inlet cavity.
[0032] Further options, such as Figure 1 As shown, the seat mounting bracket 2 is equipped with a front baffle 5 with a grille at the opening surface to isolate the air duct 3 from the driver, so as to prevent the air duct 3 from coming into contact with the driver's body and causing burns to the driver.
[0033] As can be seen from the above, the addition of air intake and exhaust ducts to the cab floor divides the cab into two air chambers by arranging the air intake duct outside the seat mounting bracket and the air exhaust duct inside the seat mounting bracket, thereby improving the air heating and circulation efficiency. The addition of air intake and exhaust ducts to the cab floor also allows for adjustment of the position of the lower heater assembly according to actual conditions, making the arrangement of the heater assembly more flexible.
[0034] Example 2: The seat mounting bracket is bolted to the cab floor, and the seat mounting bracket and the cab floor form a mounting cavity. The seat mounting bracket is only open on the side facing the driver. The mounting cavity is further divided into mounting cavity a and mounting cavity b by a partition. The air inlet is located in mounting cavity a to form an air intake cavity, and the air outlet is located in mounting cavity b to form an air outlet cavity.
[0035] A further solution involves equipping the opening of the seat mounting bracket with a front baffle with a grille to isolate the air duct from the driver, preventing the air duct from coming into contact with the driver's body and causing burns.
[0036] As can be seen from the above, the addition of air intake and exhaust ducts to the cab floor divides the seat mounting bracket into two chambers, with the air intake and exhaust ducts placed in the two chambers of the seat bracket respectively, thereby dividing the cab into two air chambers to improve the air heating and circulation efficiency. The addition of air intake and exhaust ducts to the cab floor also allows for adjustment of the position of the lower heater assembly according to actual conditions, making the arrangement of the heater assembly more flexible.
[0037] The following provides further explanation of the installation method for the aforementioned heater assembly.
[0038] like Figure 1 , Figure 3 As shown, a mounting plate 11 is provided on the bottom surface of the cab floor 6. The heater mounting bracket 7 and the bracket sealing plate 9 are fixed to the mounting plate 11 by bolts 8. The heater assembly 10 is disposed in the storage cavity formed by the heater mounting bracket 7 and the bracket sealing plate 9. The heater assembly 10 can be inspected by disassembling the heater mounting bracket 7 and / or the bracket sealing plate 9.
[0039] Further options, such as Figure 3 As shown, a sealing sponge 12 is provided between the mounting plate 11 and the heater mounting bracket 7 and the bracket sealing plate 9 to enhance the sealing effect between the mounting bracket 7 and the bracket sealing plate 9 and the mounting plate 11.
[0040] In summary, this utility model provides a cab heater installation structure. The cab floor plate 6 has two holes, one of which serves as an air inlet and the other as an air outlet. Air ducts are welded to the two holes, one of which is an air inlet duct 4 and the other is an air outlet duct 3. Air enters the heater assembly 10 from the cab through the left air inlet duct, and hot air is blown out from the right air outlet duct 3 through the seat mounting bracket 2. The seat mounting bracket 2 inside and outside the cab is divided into an air outlet chamber and an air inlet chamber to improve the air heating circulation efficiency. The hot air blows directly on the driver and does not obstruct the air conditioning from blowing into the cab.
[0041] Using the cab heater mounting structure provided by this utility model, the installation of the heater assembly 10 can be made more flexible without raising the seat mounting bracket 2, thus maintaining seat comfort and the structural strength and rigidity of the floor. Furthermore, the cab heater mounting structure also includes a front baffle 5, which is mounted on the seat mounting bracket 2 on the side closest to the driver, isolating the air duct 3 from the driver to prevent contact between the air duct 3 and the driver's body, which could result in burns.
[0042] A sealing sponge 13 is wrapped between the air outlet duct 3 and the air outlet of the heater assembly 10 to enhance the sealing effect between the air outlet duct 3 and the heater assembly 10. Similarly, a sealing sponge 12 is attached to the mounting plate 11 to enhance the sealing effect between the mounting bracket 7 and the bracket sealing plate 9 and the mounting plate 11.
[0043] The heater mounting bracket 7 and the bracket sealing plate 9 are both fixedly connected to the mounting plate 11 on the cab floor 6 by bolts 8. When the heater assembly 10 needs to be inspected, only the bolts 8 of the heater mounting bracket 7 and the bracket sealing plate 9 need to be removed, and the heater assembly can be inspected from the bottom without removing the seat assembly 1, which greatly simplifies the inspection process.
