Description

Technical Field

[0001] This utility model relates to the field of vehicle air conditioning technology, specifically to a ventilation and air conditioning component for a vehicle cab. Background Technology

[0002] Currently, there are two main types of air conditioning systems for vehicle cabs, especially truck cabs: one is the air conditioning system that comes with the vehicle, and the other is an air conditioning system that the user purchases and installs. The air conditioning system that the user purchases and installs is a supplement to the air conditioning system that comes with the vehicle, especially since the air conditioning system that comes with trucks often has poor cooling or heating performance.

[0003] There are currently two types of vehicle cabin air conditioners purchased by users: one is an integrated type, which requires a large installation opening in the roof, and the other is a split type, similar to household split air conditioners. Except for a few high-end models, most of these split air conditioners do not have the effect of ventilating and circulating air between the cabin and the outside. In the few high-end air conditioners that do have ventilation and circulation, the ventilation filter is located inside the air conditioner, which is troublesome for users to clean, especially since vehicles are driven outdoors for a long time and come into contact with a lot of dust, so the filter needs to be maintained more frequently. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A ventilation and air conditioning assembly for a vehicle cab includes an air conditioning assembly installed on the vehicle cab body. The air conditioning assembly includes a split-type outdoor unit and a split-type indoor unit. An air conditioning mounting bracket is installed on the rear side of the vehicle cab body. The split-type outdoor unit is installed on the air conditioning mounting bracket, and the split-type indoor unit is installed inside the vehicle cab body. A ventilation assembly is installed above the split-type outdoor unit. The ventilation assembly includes an air outlet duct, a connecting cover, a filter box, an air outlet box, and an air inlet duct that connect the inside and outside of the vehicle cab body. The air outlet duct, connecting cover, filter box, air outlet box, and air inlet duct are connected in sequence. The top of the filter box is open, and a cover is installed at the opening. Multiple equally spaced partitions are fixed inside the filter box, and filter cotton is placed in the filter box between adjacent partitions.

[0006] Furthermore, the air inlet duct has openings at both the front and rear, the air outlet box is installed at the rear opening of the air inlet duct, the filter box is installed at the rear end of the air outlet box, and strip-shaped openings are provided at the middle positions of both the front and rear sides of the filter box. The air outlet box abuts against the strip-shaped opening on the front side of the filter box, and the connecting cover is installed at the strip-shaped opening on the rear side of the filter box. These elements form a continuous structure, providing a complete and relatively enclosed ventilation path.

[0007] Furthermore, a roller is installed inside the air inlet duct, with bearing seats installed at both ends. The roller is mounted to the bearing seats at corresponding positions at both ends, and multiple strip-shaped fan blades are fixed on the roller between the bearing seats. A motor is installed on the outside of the air inlet duct at one end corresponding to the roller, and the motor's output end is fixedly connected to the roller at the corresponding position. The strip-shaped fan blades can be horizontally lengthened to obtain a larger air intake surface. Compared to round fan blades, the strip-shaped blades have a limited volume, making them more suitable for use in vehicle cabs.

[0008] Furthermore, the outer side of the strip-shaped fan blades is close to the inner wall of the air inlet, and a mesh cover is installed at the front opening of the air inlet. When not rotating, the strip-shaped fan blades can provide wind protection and also prevent small insects from entering. Compared with round fan blades, the strip shape has better sealing properties.

[0009] Furthermore, the air conditioner mounting bracket includes two parallel support frames. Support plates are fixedly installed on the top and bottom of the front of each support frame. Fixing plates are mounted on the support plates, and outer support plates are fixed on the fixing plates. Inner support plates are provided inside the outer support plates, and the inner sides of the inner support plates abut against the four corners of the split-type air conditioner outdoor unit to form support. Multiple springs at equal intervals are fixed between the inner and outer support plates. The springs can partially offset the vibration force transmitted to the split-type air conditioner outdoor unit when the cab is bumpy, thereby reducing the vibration of the split-type air conditioner outdoor unit.

[0010] Furthermore, limit strips are fixed at both ends of the outer support plate, and gaps are reserved between the limit strips and the corresponding ends of the inner support plate. This restricts the displacement of the inner support plate and prevents it from detaching from the outer support plate.

[0011] Furthermore, a diagonal brace is fixed to the bottom front of the support frame, and the diagonal brace is fixed to the corresponding support plate. The two support frames are fixed together by multiple connecting plates. This makes the entire mounting frame a whole, while increasing the structural strength of the entire mounting frame and providing reliable installation for split-type air conditioner outdoor units.

[0012] Furthermore, a buffer pad is installed on the support frame at the position corresponding to the inner support plate. The rear side of the inner support plate abuts against the buffer pad at the corresponding position, and a baffle is fixed to the front end of the outer support plate, abutting against the front of the split-type air conditioner outdoor unit. The buffer pad and the baffle can restrain the split-type air conditioner outdoor unit, restrict its movement, and provide better installation stability.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up an independent ventilation component, does not affect the use of existing split-type air conditioners. At the same time, the air filtration cotton of the ventilation component is set in the filter box, which is easy to open, so that the filter cotton can be easily cleaned or replaced.

[0015] 2. In this utility model, external air is drawn into the air inlet duct by rotating strip-shaped fan blades, then filtered and purified before being introduced into the cab. The strip-shaped fan blade structure can control the volume to make it suitable for installation and use in the vehicle cab.

[0016] 3. In this utility model, the outdoor unit of the split air conditioner is supported by inner and outer support plates. The inner support plate abuts against the four corners of the outdoor unit of the split air conditioner, which can provide good support stability.

[0017] 4. In this utility model, by setting a spring between the inner and outer support plates, the spring can partially offset the vibration force transmitted to the outdoor unit of the split air conditioner when the cab is bumpy, thereby reducing the vibration of the outdoor unit of the split air conditioner and providing a certain protection effect for the electrical components inside the outdoor unit of the split air conditioner.

[0025] 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.

[0026] This application provides a ventilation and air conditioning component for a vehicle cab, mainly addressing the problems that some split-type air conditioners used in vehicle cabs lack ventilation for both the interior and exterior, while others that do offer ventilation suffer from inconvenient air filter cleaning and maintenance. The application provides the following technical solution, which will be discussed in conjunction with... Figure 1 - Figure 6 Please provide a detailed explanation:

[0027] A ventilation and air conditioning assembly for a vehicle cab includes an air conditioning assembly 2 and a ventilation assembly 3 installed on the vehicle cab body 1. The air conditioning assembly 2 includes a split-type outdoor air conditioning unit 21 and a split-type indoor air conditioning unit 22. An air conditioning mounting bracket 4 is installed on the rear side of the vehicle cab body 1. The split-type outdoor air conditioning unit 21 is installed on the air conditioning mounting bracket 4. The split-type indoor air conditioning unit 22 is installed above the driver's seat or above the passenger seat inside the vehicle cab body 1. The air conditioning assembly 2 is an existing split-type air conditioning unit. The refrigerant evaporates and absorbs heat in the indoor unit to cool the cab. Then, the outdoor unit condenses the refrigerant after absorbing heat. The condensed refrigerant is then circulated back to the indoor unit to evaporate and absorb heat, forming a cycle of cooling.

[0028] The ventilation assembly 3 is installed above the outdoor unit 21 of the split air conditioner. The ventilation assembly 3 includes an air inlet duct 31 with openings at the front and rear. A mesh cover 310 is installed at the front opening and an air outlet box 32 is installed at the rear opening. A roller 37 is installed inside the air inlet duct 31. A bearing seat 314 is installed at both ends inside the air inlet duct 31. The two ends of the roller 37 are installed with the bearing seat 314 at the corresponding positions. Multiple strip-shaped fan blades 38 are fixed on the roller 37 between the two bearing seats 314. The outer side of the strip-shaped fan blades 38 is close to the inner wall of the air inlet duct 31. A motor 39 is installed on the outer side of the air inlet duct 31 at one end of the roller 37. The output end of the motor 39 is fixedly connected to the roller 37 at the corresponding position.

[0029] A filter box 33 is installed at the rear end of the air outlet box 32, which is away from the air inlet duct 31. A strip-shaped opening 313 is opened in the middle of both the front and rear sides of the filter box 33. The air outlet box 32 is close to the strip-shaped opening 313 on the front side of the filter box 33. The top of the filter box 33 is open, and a box cover 311 is installed at the opening. Multiple spacers 312 with equal spacing are fixed inside the filter box 33. Filter cotton 34 is placed in the filter box 33 between adjacent spacers 312. An air outlet pipe 36 is installed on the rear side of the filter box 33, which is away from the air inlet duct 31. A connecting cover 35 is installed between the front end of the air outlet pipe 36 and the strip-shaped opening 313 on the rear side of the filter box 33. The air outlet pipe 36, the connecting cover 35, the filter box 33, the air outlet box 32, and the air inlet duct 31 connect the inside and outside of the vehicle cab body 1.

[0030] When in use, the existing air conditioning components 2 provide cooling or heating. When ventilation of the cab is required, the control motor 39 is turned. The rotation of the motor 39 drives the roller 37 and the strip fan blades 38 on the roller 37 to rotate. The rotation of the strip fan blades 38 brings in outside air through the mesh cover 310 and then sends it out through the air outlet box 32. The air is sent into the filter box 33 through the air outlet box 32. In the filter box 33, the air is filtered by the filter cotton 34 to remove dust and other foreign objects and then enters the air outlet pipe 36 through the connecting cover 35. The air outlet pipe 36 is connected to the vehicle cab body 1 to provide ventilation. The driver can open some of the cab windows at the same time to obtain a positive pressure ventilation effect in the cab, or keep the cab doors and windows closed and let the air flow out through the inherent gaps in various positions of the cab.

[0031] Meanwhile, due to the structure of the strip fan blades 38 and the air inlet duct 31, when the motor 39 is not working, the external airflow that wants to enter the cab through the ventilation assembly 3 is not only blocked by the filter cotton 34, but also blocked by the strip fan blades 38 near the inner wall of the air inlet duct 31. When there is no ventilation, the entry of external air can be greatly reduced, and in the cold environment outside the vehicle, the penetration of cold air can be greatly reduced.

[0032] In some embodiments, the air conditioner mounting bracket 4 includes two parallel support brackets 41, which are fixed together by multiple connecting plates 42. Support plates 48 are fixedly installed on the top and bottom of the front of the support brackets 41. Fixing plates 47 are installed on the bottom of the top support plate 48 and the top of the bottom support plate 48. An outer support plate 43 is fixed on the fixing plate 47. An inner support plate 44 is provided on the inner side of the outer support plate 43. The inner side of the inner support plate 44 abuts against the four corners of the split air conditioner outdoor unit 21 to form support. Multiple springs 46 at equal intervals are fixed between the inner support plate 44 and the outer support plate 43. A baffle 45 is fixed at the front end of the outer support plate 43 to abut against the front of the split air conditioner outdoor unit 21.

[0033] During installation, holes need to be drilled on the rear side of the vehicle cab body 1, and then bolts are used to fix the support frame 41 to the vehicle cab body 1. First, install the outer support plate 43 and inner support plate 44 at the bottom of the support frame 41, and then install the split air conditioner outdoor unit 21, so that the inner support plate 44 supports the bottom sides of the split air conditioner outdoor unit 21. Then, install the outer support plate 43 and inner support plate 44 at the top of the support frame 41, so that the upper inner support plate 44, together with the lower inner support plate 44, provides a surrounding constraint support for the four sides of the split air conditioner outdoor unit 21. At the same time, when the vehicle cab body 1 is bumpy, the vibration can be partially absorbed by the spring 46, thereby reducing the vibration amplitude of the split air conditioner outdoor unit 21, so as to ensure the installation reliability of the internal electrical components and avoid vibration damage.

[0034] In some embodiments, both ends of the outer support plate 43 are fixed with limit strips 410, and the limit strips 410 at both ends are reserved with the corresponding ends of the inner support plate 44. A diagonal brace 49 is fixed at the bottom of the front of the support frame 41, and the diagonal brace 49 is fixed with the corresponding support plate 48.

[0035] The limiting strip 410 can limit the displacement of the inner support plate 44 when it vibrates, and prevent it from coming off the outer support plate 43. During installation, the weight of the split air conditioner outdoor unit 21 is basically supported by the support plate 48 at the bottom of the support frame 41. Therefore, the diagonal brace 49 is set to increase the stability of the support.

[0036] In some embodiments, a buffer pad 411 is installed on the support frame 41 at the position corresponding to the inner support plate 44, and the rear side of the inner support plate 44 abuts against the buffer pad 411 at the corresponding position. The buffer pad 411 is a rubber pad.

[0037] During installation, the buffer pad 411 is placed against the rear side of the split air conditioner outdoor unit 21, and the baffle 45 is used to restrain the split air conditioner outdoor unit 21 to prevent it from sliding inside the inner support plate 44.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
