[0004] At present, the housing of the automobile air-conditioning outlet usually adopts a split structure. The automobile air-conditioning outlet disclosed in the Chinese patent with publication number CN220429820U and patent name "A Automobile Air Outlet" includes an outer shell, vertical blades, dampers, and a driving motor. The driving motor is fixed on the outer shell, the driving motor is connected to a cam, a driving rib is arranged on the cam, the driving rib is connected to a blade rack, the blade rack is connected to a blade gear, the blade gear is connected to the vertical blade, the cam is connected to the damper slider through a driving round pin, a rack is arranged on the damper slider and connected to the damper gear, the damper gear drives the damper, an inner shell is arranged in the outer shell, the outer shell includes an upper shell and a lower shell, the driving motor is fixed to the outer shell through a motor bracket, a plurality of vertical blades are connected in series to form a blade group through a blade fixing rod, the driving round pin and the cam can be an integral structure, and can also be set to a split structure, that is, a collar is arranged on the driving round pin, and the driving round pin is sleeved on the cam.

[0005] The above-mentioned automobile air-conditioning outlet divides the shell into an outer shell and an inner shell, and the outer shell is composed of an upper shell and a lower shell. This split structure is mainly convenient for the molding and assembly of the shell, reducing the difficulty of production. However, as the car is used for a longer time, affected by factors such as ambient temperature, humidity and vibration, the split shell is prone to cracks, deformation or loosening, resulting in abnormal noise, affecting the driving experience, and the abnormal noise of the automobile air-conditioning outlet is often difficult to be detected in time, affecting maintenance.

[0006] In addition, the grid plate group is composed of a plurality of horizontal grid plates, vertical grid plates and mounting brackets. Each grid plate is uniformly inserted into the air outlet end of the shell through the mounting bracket and then rotatably connected to the shell. As shown in the Chinese patent with publication number CN220615428U and patent name "A Automobile Air Conditioner Air Outlet", it includes a shell, vertical blades, horizontal blades, a first drive assembly and a second drive assembly. The shell includes an upper shell and a lower shell that are connected to each other. The upper shell and the lower shell are symmetrically arranged and open at both ends. The two ends of the shell form an air inlet and an air outlet. The shell is A panel is connected to the air outlet, a receiving space is formed inside the shell, an air duct is formed in the receiving space, a plurality of semicircular grooves are provided on the sides of the upper shell and the lower shell that are close to each other, the two semicircular grooves are combined into a through hole, so that a plurality of through holes are provided on both sides of the shell, the horizontal blades include an upper horizontal blade and a lower horizontal blade, the upper horizontal blade is located on the side of the receiving space close to the air outlet, the lower horizontal blade is located on the side of the receiving space close to the air inlet, a first rotating shaft and a second rotating shaft are also provided in the receiving space, and the first rotating shaft and the second rotating shaft are rotatably connected to the shell through the through hole The upper horizontal blade is connected to the first rotating shaft, and the lower horizontal blade is connected to the second rotating shaft.

A vertical blade bracket is arranged in the middle of the accommodating space, and the vertical blade bracket is connected to the upper shell and the lower shell. The vertical blade bracket includes a first bracket and a second bracket. The width of the first bracket and the second bracket is the same as the width of the accommodating space, so that the airflow passes through the upper and lower sides of the first bracket and the second bracket. The cross section of one end of the second bracket is Y-shaped, and a through groove is provided at the top of the side of the second bracket close to the first bracket. The second bracket is embedded in the through groove. A circular through hole and an accommodating cavity are jointly provided on the side where the second bracket and the first bracket are close to each other. The first bracket and the second bracket are jointly rotatably connected to multiple rotating shafts through the through holes. The vertical blades are connected to the two ends of the rotating shaft, and the multiple vertical blades located on the same side of the rotating shaft are jointly connected to the vertical blade connecting rod. The vertical blades are used to guide the wind direction. The vertical blades are driven to rotate by the rotation of the rotating shaft, and the multiple vertical blades are driven to rotate synchronously by the vertical blade connecting rod, so that the left and right wind directions can be changed.

[0007] The problem with the above structure is that the bracket of the horizontal blade needs to extend into the air duct of the shell, and the air duct is relatively narrow, which makes it difficult to install the horizontal blade, affecting the installation efficiency of the entire air outlet of the air conditioner. Utility Model Content

[0008] In view of the above situation, in order to overcome the problem that the shell of the automobile air-conditioning outlet in the above-mentioned prior art is a split structure, and as the use time of the car increases, the shell is prone to abnormal noise, affecting the driving experience, and the abnormal noise is often difficult to detect in time, affecting maintenance, and at the same time, the horizontal grid plate of the grid plate group is difficult to install into a narrow air duct, affecting the installation efficiency, the purpose of the utility model is to provide an integrated structure, which has high structural strength and is not prone to abnormal noise as the use time of the car increases, so that the driver has a better driving experience and reduces the maintenance frequency. At the same time, the horizontal grid plate of the grid plate group is easy to install, thereby greatly improving the installation efficiency of the automobile air-conditioning outlet shell.

[0009] In order to achieve the above purpose, the technical solution of the utility model is:

[0010] The invention discloses an automobile air-conditioning air outlet shell with which a horizontal grid plate can be easily installed. The invention comprises a front shell and a rear shell. Both the front shell and the rear shell are hollow tubular structures. The front shell and the rear shell are connected through an opening on the approaching side and are integrally formed. An air duct is formed inside the front shell and the rear shell, and the opposite ends are respectively an air inlet end and an air outlet end. An engaging position for connecting with the horizontal grid plate of the same grid plate group is formed on two opposite side walls in the horizontal direction of the air outlet end. The engaging position comprises an outer card slot and an inner card slot. The outer card slot and the inner card slot are respectively formed on the outer side wall and the inner side wall of the air outlet end and are connected to each other.

[0028] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of simplifying the description, and do not indicate or imply that the directions are specific directions that must be possessed and specific directions, structures, and operations, and therefore should not be understood as limitations on the present utility model.

[0030] like Figures 1 to 3 as well as Figure 5 As shown, the utility model relates to an automobile air-conditioning outlet housing with an easily installed horizontal grid plate, which comprises a front housing 1 and a rear housing 2, both of which are hollow tubular structures, and both ends of the front housing 1 and the rear housing 2 are open, the front housing 1 and the rear housing 2 are connected through the opening of the approach side, and are integrally formed, so that the outer walls of the front housing 1 and the rear housing 2 are continuous without joints, and have higher overall strength and rigidity than the split structure, thereby reducing the negative impact of external factors such as ambient temperature, humidity and vibration on the stability of the overall structure, ensuring that the overall structure can be stable and reliable even when the automobile is driven for a long time, reducing the possibility of abnormal noise, improving the driving experience of the driver, and also reducing the maintenance frequency;

[0031] An air duct is formed inside the front shell 1 and the rear shell 2, and the opposite ends are respectively an air inlet end 101 and an air outlet end 201. The two opposite side walls in the horizontal direction of the air outlet end 201 are formed with a bite position for connecting to the horizontal grid plate 3 of the same grid plate group. More specifically, the bite position is used to connect to the bracket of the same horizontal grid plate 3. The bite position consists of an outer card slot 202 and an inner card slot 203. The outer card slot 202 and the inner card slot 203 are respectively formed on the outer side wall and the inner side wall of the air outlet end 201, and are connected to each other. The bite position also includes a first step surface 204 at the transition between the outer card slot 202 and the inner card slot 203. Correspondingly, two groups of boss structures with height difference matching the outer card slot 202 and the inner card slot 203 are also formed on the bracket of the horizontal grid plate 3, which are respectively plugged into the outer card slot 202 and the inner card slot 203, and step-matched with the first step surface 204. In the mating state, the movement of the horizontal grid plate 3 relative to the entire shell is restricted, the connection stability is improved, and the assembly accuracy is improved. At the same time, there are multiple external card slots 202, and each external card slot 202 is arranged at intervals along the length direction of the outer side wall. It can be understood that this also makes the horizontal grid plate bracket have multiple boss structures for mating with the external card slots 202, and the number and spacing are equal to form a staggered plug-in, thereby increasing the docking area between the shell of the utility model and the horizontal grid plate bracket. When subjected to external force, it is more difficult to separate, and the connection strength is improved. The bite position is located at the opening of the air outlet end 201 of the rear shell 2. When assembling the horizontal grid plate bracket, the plug-in can be completed directly on the outside through relative movement, which simplifies the steps of inserting into a narrow air duct for plug-in, greatly reduces the difficulty of installing the horizontal grid plate, and improves the installation efficiency.

[0032] like Figures 1 to 3 As shown, the engaging position also includes side slots 205 formed at both ends of the inner slot 203, and the width of the side slots 205 is smaller than that of the inner slot 203. As a whole, the side slots 205 are between the outer slot 202 and the inner slot 203. When the housing of the utility model and the bracket of the horizontal grid plate are in the mating state, the docking area between the two is further increased, while better limiting relative movement, so that the stability of the connection is further improved.

[0033] like Figures 1 to 3 As shown, the inner diameter of each outer slot 202 and inner slot 203 close to the rear shell 2 is smaller than the inner diameter of the other opposite side. It can be understood that the inner diameter of the closed end of the outer slot 202 and the inner slot 203 is smaller than the inner diameter of the opening. Correspondingly, the boss structure on the horizontal grid plate bracket has the same shape of the small diameter section and the large diameter section. When plugging and mating, the small diameter section is first embedded in the large inner diameter section, and then through relative movement, the small diameter section is matched with the small inner diameter section, and the large diameter section is matched with the large inner diameter section to complete the plug-in, thereby reducing the difficulty of plug-in.

[0034] like Figure 1 as well as Figures 3 to 5 As shown, the diameter of the rear shell 2 increases gradually from one side close to the front shell 1 to the other side, and the air outlet end 201 forms a bell mouth. Based on the above arrangement, the air outlet volume is increased to cover a wider area, thereby improving the air supply effect, improving the air convection effect in the vehicle, and ensuring that the air is more evenly distributed to various areas in the vehicle, avoiding local overheating or overcooling, and improving the comfort of passengers.

[0035] like Figure 1 as well as Figures 3 to 5 As shown, the outer wall of the docking position of the front shell 1 and the rear shell 2 is formed with a second step surface 206, and the second step surface 206 cooperates with the step of the car dashboard to block and limit the shell of the utility model, so as to avoid over-movement during assembly and improve assembly accuracy.

[0036] like Figure 1 as well as Figures 3 to 5 As shown, first mounting holes 102 which are opposite to each other and which pass through the air duct are formed on the two side walls of the front shell 1, and two ends of the air door 4 are rotatably connected to the two first mounting holes 102. A first mounting position 103 is formed on the outer wall of the front shell 1 around the first mounting hole 102 on either side. The front swing arm 5 of the transmission mechanism is rotatably connected to the first mounting position 103 and is rotatably connected to the air door 4. The rotation of the front swing arm 5 can directly drive the air door 4 to rotate. A second mounting position 207 is formed on the side wall of the rear shell 2 on the same side as the first mounting position 103. The knob 6 is rotatably connected to the second mounting position 207. The rear swing arm 7 is rotatably connected to the front swing arm 5 and the knob 6. The driver first drives the rear swing arm 7 to rotate by rotating the knob 6, and then the rear swing arm 7 drives the front swing arm 5 to rotate, and finally the air door 4 rotates, thereby realizing the opening and closing of the air duct.

[0037] like Figures 1 to 5 As shown, a plurality of external undercuts 208 for connecting and fixing with a car dashboard are formed on the outer wall of the rear shell 2. In the utility model, the external undercuts 208 are distributed on the circumferential outer wall of the air duct outlet end 201 of the rear shell 2, and a multi-point fixing method is used to increase the stability with the connected car dashboard.

[0038] like Figure 1 , Figure 3 and Figure 5 As shown, an upper hinge position 209 and a lower hinge position 210 for connecting to the vertical grid plates 8 of the grid plate group are formed on the upper and lower inner walls of the rear shell 2. There are multiple upper hinge positions 209 and lower hinge positions 210, which are arranged at intervals with each other to avoid interference between the vertical grid plates 8 and ensure that the vertical grid plates 8 can be arranged without interference.

[0039] Combination Figures 1 to 5The automobile air-conditioning outlet shell of the utility model is composed of an integrally formed front shell 1 and a rear shell 2. Compared with the split structure, it has higher overall strength and rigidity, thereby reducing the negative impact of external factors such as ambient temperature, humidity and vibration on the stability of the overall structure, ensuring that the automobile can run for a long time and can also ensure the stability and reliability of the overall structure, reduce the possibility of abnormal noise, improve the driving experience of the driver, and also reduce the maintenance frequency. The rear shell 2 uses the bite position on the air outlet end 201 of the air duct to plug and cooperate with the bracket of the horizontal grid plate 3. The bite position is located at the opening of the air outlet end 201, and can form a step and concave-convex cooperation with the bracket of the horizontal grid plate 3, so that the two can be firmly connected, and the air outlet end 201 is configured as a trumpet to increase the air volume, ensure that the air is more evenly distributed to various areas in the car, avoid local overheating or overcooling, and improve the comfort of passengers. When it is assembled with the automobile dashboard, it also uses the step to improve the assembly accuracy, and uses multiple external undercuts 208 to increase the connection stability by multi-point fixation.

[0040] The above embodiments and descriptions are only for explaining the principle and the best embodiment of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
