Abstract

This invention discloses a method for installing a parking air conditioner. By setting blind holes on the base, the depth of which is greater than the depth of the first threaded section, the first threaded section at the top of the mounting bolt can be fully screwed into the chassis, thus controlling the depth to which the mounting bolt is screwed into the chassis. A limiting nut restricts the effective length L4 of the second threaded section on the mounting bolt. Before installation, the optimal thickness L1 of the waterproof gasket, the height L2 of the roof window or roof bracket, and the height L3 of the lower fixed bracket are measured. By controlling L4 = L1 + L2 + L3, the operator only needs to simultaneously operate the mounting bolt and the limiting nut until the first threaded section is fully tightened into the blind hole. This automatically compresses the waterproof gasket to the optimal thickness L1. The entire installation process relies entirely on data, eliminating the need for the operator to judge the tightening degree of the mounting bolt based on their own experience, making installation more convenient and simple.

Description

Technical Field

[0001] This invention relates to the field of parking air conditioners, and in particular to a method for installing a parking air conditioner. Background Technology

[0002] A parking air conditioner is an air conditioner installed on the roof of a vehicle. It requires a roof window or a sunroof. During installation, the chassis of the parking air conditioner is fixed to the roof, and the waterproof gasket at the bottom of the unit is pressed firmly against the roof. It is then secured to the top of the vehicle body using a lower fixing bracket, and finally bolted to the chassis bottom by passing through the lower fixing bracket and the roof window. The tightness of the waterproof gasket is directly proportional to the depth of the bolts screwed into the chassis. This leads to a problem: because the roof thickness varies between different car models, the bolt depth is not a fixed value. This means the bolt depth relies entirely on the installer's feel, resulting in significant uncertainty and requiring a high level of skill. If the bolt depth is too low, the waterproof gasket will not be compressed enough, leading to water leakage. If the bolt depth is too high, the waterproof gasket will be over-compressed, which can easily damage the gasket and put excessive tension on the parking air conditioner chassis, making it prone to deformation and breakage. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a method for installing a parking air conditioner that digitizes the entire installation process, thereby standardizing the installation process and reducing the experience requirements for installers.

[0004] The technical solution adopted by this invention to solve the problem is: an installation method for a parking air conditioner, wherein the parking air conditioner includes an air conditioner body, a chassis located at the bottom of the air conditioner body, a waterproof sealing gasket located at the bottom of the chassis, a lower fixing bracket, mounting bolts, and a limiting nut. A metal threaded sleeve is provided at the bottom of the chassis, and a threaded blind hole is provided at the bottom of the metal threaded sleeve. The depth of the threaded blind hole is S1. A first operating part is provided at the bottom of the mounting bolt. The mounting bolt includes a second threaded segment at its lower end and a first threaded segment located at the top of the second threaded segment. The length of the first threaded segment is d1, where d1 ≤ S1. The diameter of the first threaded segment is smaller than the diameter of the second threaded segment. A second operating part is provided on the limiting nut. The installation method includes:

[0005] 1. Based on the performance of the waterproof sealing gasket, find out the optimal compression thickness L1 of the waterproof sealing gasket, measure the height of the roof window or the roof bracket L2, and measure the height L3 from the bottom surface of the lower fixing bracket to the position where the lower fixing bracket abuts against the bottom surface of the roof window or the bottom surface of the roof bracket.

[0006] 2. Fit the limiting nut into the second threaded section and adjust the height of the limiting nut on the second threaded section so that the distance between the limiting nut and the top surface of the second threaded section is L4 = L1 + L2 + L3;

[0007] 3. Install the waterproof sealing gasket, chassis, and air conditioning unit on the top of the roof window or the top of the roof bracket. The waterproof sealing gasket surrounds the roof window. Place the lower fixing bracket from inside the vehicle body on the bottom surface of the roof window or the bottom surface of the roof bracket. Pass the mounting bolt through the lower fixing bracket and screw the first threaded section into the threaded blind hole. Use tools to operate the first and second operating parts simultaneously, so that the first threaded section is continuously screwed into the threaded blind hole until the top of the second threaded section abuts and locks against the bottom surface of the metal sleeve.

[0008] As a further improvement to the above technical solution, the first operating part is an external hexagonal head, and the second operating part is an external hexagonal operating surface disposed on the outer periphery of the limiting nut. The external hexagonal operating surface has the same outer periphery size as the external hexagonal head. In the step, after adjusting the height of the limiting nut on the second thread section, it is necessary to finely adjust the angle of the limiting nut so that the outer end face of the external hexagonal head and the external hexagonal operating surface are on the same plane. The tool is a hexagonal socket wrench that can simultaneously fit the external hexagonal head and the external hexagonal operating surface inside it.

[0009] The beneficial effects of this invention are as follows: By ensuring the depth of the blind hole is greater than the depth of the first threaded section, the first threaded section can be fully screwed into the chassis, thereby controlling the depth to which the mounting bolt is screwed into the chassis. The effective length L of the second threaded section is limited by the limiting nut. Before installation, the optimal thickness L of the waterproof gasket, the height L of the roof window or roof bracket, and the height L of the lower fixed bracket are measured. By controlling L = L + L + L, the operator only needs to simultaneously operate the mounting bolt and the limiting nut until the first threaded section is fully tightened into the blind hole, which will automatically compress the waterproof gasket to the optimal thickness L. The entire installation process relies entirely on data, eliminating the need for the operator to judge the tightening degree of the mounting bolt based on their own experience, making installation more convenient and simple.

[0010] The invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0011] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention;

[0012] Figure 2 for Figure 1 A magnified schematic diagram of the structure at point A;

[0013] Figure 3 This is a structural diagram of the mounting bolts. Detailed Implementation

[0014] Reference Figures 1 to 3A method for installing a parking air conditioner, wherein the parking air conditioner includes an air conditioner body, a chassis 10 located at the bottom of the air conditioner body, a waterproof sealing gasket 20 located at the bottom of the chassis 10, a lower fixing bracket 30, mounting bolts 50, and a limiting nut 60. A metal threaded sleeve 40 is provided at the bottom of the chassis 10, and a threaded blind hole with a depth of S1 is provided at the bottom of the metal threaded sleeve 40. The mounting bolt 50 has a first operating part at its bottom, and includes a second threaded section 52 at its lower end and a first threaded section 51 at the top of the second threaded section 52. The length of the first threaded section 51 is d1, where d1 ≤ S1, and the diameter of the first threaded section 51 is smaller than the diameter of the second threaded section 52. A second operating part is provided on the limiting nut 60. The installation method includes the following steps:

[0015] 1. Based on the performance of the waterproof sealing gasket 20, find out the optimal compression thickness L1 of the waterproof sealing gasket 20, measure the height of the roof window or the height of the roof bracket L2, and measure the height L3 from the bottom surface of the lower fixed bracket 30 to the position where the lower fixed bracket 30 abuts against the bottom surface of the roof window or the bottom surface of the roof bracket.

[0016] 2. Fit the limiting nut 60 into the second threaded section 52 and adjust the height of the limiting nut 60 on the second threaded section 52 so that the distance between the limiting nut 60 and the top surface of the second threaded section 52 is L4 = L1 + L2 + L3;

[0017] 3. Install the waterproof sealing gasket 20, chassis 10 and air conditioner body on the top of the roof window or the top of the roof bracket. The waterproof sealing gasket 20 surrounds the roof window. Place the lower fixing bracket 30 from inside the vehicle body on the bottom surface of the roof window or the bottom surface of the roof bracket. Pass the mounting bolt 50 through the lower fixing bracket 30 and screw the first threaded section 51 into the threaded blind hole. Use tools to operate the first operating part and the second operating part simultaneously, so that the first threaded section 51 is continuously screwed into the threaded blind hole until the top of the second threaded section 52 abuts and locks against the bottom surface of the metal threaded sleeve 40.

[0018] In the above scheme, the first operating part is preferably an external hexagonal head 53, and the second operating part is an external hexagonal operating surface disposed on the outer periphery of the limiting nut 60. The external hexagonal operating surface has the same outer periphery size as the external hexagonal head 53. In step 2, after adjusting the height of the limiting nut 60 on the second threaded section 52, it is necessary to finely adjust the angle of the limiting nut 60 so that the outer end face of the external hexagonal head 53 and the external hexagonal operating surface are on the same plane. The tool is a hexagonal socket wrench that can simultaneously fit the external hexagonal head 53 and the external hexagonal operating surface inside it.

[0019] L2 refers to the height of the roof window or the roof bracket because in different car models, some models have the parking air conditioner directly installed on the roof, while other models have a roof bracket installed at the roof window to abut against the waterproof sealing gasket 20 and the lower fixed bracket 30 in order to prevent deformation of the roof sheet metal, thus protecting the roof sheet metal.

[0020] By ensuring the depth of the blind hole is greater than the depth of the first threaded section 51, the first threaded section 51 can be fully screwed into the chassis 10, thus controlling the depth to which the mounting bolt 50 is screwed into the chassis 10. The effective length L4 of the second threaded section 52 is limited by the limiting nut 60. Before installation, the optimal thickness L1 of the waterproof sealing gasket 20, the height L2 of the roof window or roof bracket, and the height L3 of the lower fixed bracket 30 are measured. By controlling L4 = L1 + L2 + L3, the operator only needs to simultaneously operate the mounting bolt 50 and the limiting nut 60 until the first threaded section 51 is fully tightened into the blind hole. This will automatically compress the waterproof sealing gasket 20 to the optimal thickness L1. The entire installation process relies entirely on data, eliminating the need for the operator to judge the degree of tightening of the mounting bolt 50 based on their own experience, making installation more convenient and simple.

[0021] In this solution, the waterproof sealing gasket 20 can be made of various materials such as waterproof sponge and sealing rubber, and no specific restrictions are made here.

[0022] The metal threaded sleeve is preferably made of copper, which combines low cost, high strength, and high stability. In other embodiments, it can also be made of other materials such as iron or stainless steel.

[0023] In other embodiments, the mounting bolt has a screw head at its bottom, and the screw head has two sets of first through holes running vertically through it. The second operating part consists of two sets of second through holes on the mounting bolt. The tool is a screwing claw, which includes a horizontal grip and two claw bars. The claw bars can be simultaneously inserted into the first and second through holes.

[0024] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
