Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to a middle bridge and air vent assembly device. Background Technology

[0002] After the air vents of a car air conditioner are manufactured, a central bridge is usually installed in the middle area of ​​the vent to improve its aesthetics. The central bridge is used as a decorative strip.

[0003] Currently, when assembling the middle bridge and the air outlet, first place the middle bridge in the middle position at the top of the air outlet. Then, align the threaded holes at both ends of the middle bridge with the threaded holes on both sides of the air outlet. Next, the operator presses down on the top of the middle bridge with one hand, and uses the other hand to connect the opposite ends of the middle bridge to the opposite sides of the air outlet with screws.

[0004] The existing technical solutions mentioned above have the following drawbacks: when relying solely on manual assembly of the bridge and air outlet, the assembly efficiency and accuracy are low. Summary of the Invention

[0005] To improve the assembly efficiency and accuracy of assembling the middle bridge and the air outlet, this application provides an assembly device for the middle bridge and the air outlet.

[0006] This application provides a middle bridge and air outlet assembly device, which adopts the following technical solution: A middle bridge and air outlet assembly device, comprising: frame; A swivel mount is rotatably mounted on the top of the frame, with the top surface used to support the air outlet; The first driver is mounted on the top of the frame, and its output is connected to one end of the rotary base to drive the rotary base to rotate. The pressure rod can rotate and move up and down; The pressure head is installed at the bottom of one end of the pressure rod. It can rotate with the pressure rod and move up and down with the pressure rod so that the bottom end of the pressure head presses against or disengages from the top of the middle bridge. The second driver is installed on the top of the rotating base, and its output end is connected to the end of the pressure rod away from the pressure head. It is used to drive the pressure rod to rotate and move up and down. When the second actuator drives the pressure rod to rotate and move downward, the pressure head rotates and moves downward with the pressure rod to press the middle bridge against the center of the top of the air outlet.

[0007] By employing the above technical solution, the second actuator drives the pressure rod to rotate and move downwards, causing the pressure head to rotate and move downwards, thereby pressing the bottom end of the pressure head against the top of the middle bridge. Then, the first actuator drives the rotating seat to rotate 90° counterclockwise, and then installs screws from above to connect one end of the middle bridge to one side of the air outlet. Next, the first actuator drives the rotating seat to rotate 180° clockwise, and then installs screws from above to connect the other end of the middle bridge to the other side of the air outlet. Then, the first actuator drives the rotating seat to rotate 90° counterclockwise. Then, the second actuator drives the pressure rod to rotate and move upwards, causing the pressure head to rotate and move upwards, thereby detaching the pressure head from the middle bridge. Compared to relying solely on manual labor, this method can assist in the manual assembly of the air outlet and the middle bridge, improving assembly efficiency. During assembly, the middle bridge does not rotate or move relative to the air outlet, maintaining a relatively stable position, thus improving assembly accuracy and preventing deformation and tilting of the middle bridge. Furthermore, because the pressure rod is rotatable, when it reaches directly above the air outlet, it is positioned horizontally to prevent other structures at the top of the air outlet from interfering with the descent of the pressure rod and pressure head, ensuring effective pressure. This also prevents the pressure rod from obstructing the opposite sides of the air outlet, facilitating screw installation by the operator. Once the pressure head detaches from the middle bridge, the pressure rod and pressure head can avoid obstructing the air outlet and middle bridge, making it easy to place and remove the air outlet and middle bridge.

[0008] This application further includes: The first limiting component is installed on one side of the top of the frame; And / or, a second limiting component, mounted on the other side of the top of the rack.

[0009] By adopting the above technical solution, the first limiting component is used to limit the rotation amplitude when the rotating seat rotates clockwise, and the second limiting component is used to limit the rotation amplitude when the rotating seat rotates counterclockwise.

[0010] This application further specifies that the first limiting component includes: The first limit seat is installed at the top of the frame; The buffer is mounted on the first limit seat; When the rotating seat rotates, it can press against the top of the buffer to limit the rotation of the rotating seat; The structure of the second limiting component is the same as that of the first limiting component.

[0011] By adopting the above technical solution, the buffer can absorb and mitigate the impact force of the rotating seat, reduce the degree of damage caused by the impact, and extend its service life.

[0012] The application further specifies that: a second limiting seat is formed on the top surface of the rotating seat; the second limiting seat can be detachably connected to the bottom end of the air outlet.

[0013] By adopting the above technical solution, the second limiting seat can restrict the movement of the air outlet within the plane where the second limiting seat is located, thereby improving the stability of the air outlet position and thus helping to ensure assembly accuracy.

[0014] This application further includes: The positioning sensor, installed on the top of the rotating base, is used to detect whether the air outlet is in position.

[0015] By adopting the above technical solution, the positioning detection sensor is used to detect whether the air outlet is in position and can send the detection signal to the controller.

[0016] This application further includes: The controller is mounted on the rack and is connected to the first driver, the second driver, and the position detection sensor.

[0017] This application further includes: There are two support bases, which are respectively installed at opposite ends of the top of the frame; one support base is rotatably connected to one end of the rotating base, and the other support base is fixedly connected to the fixed end of the first driver.

[0018] This application is further configured such that: a limiting protrusion is formed at the bottom of the pressure head; and the top of the pressure head and the bottom of the pressure rod are detachably connected by bolts.

[0019] By adopting the above technical solution, when the bottom end of the pressure head presses against the top end of the middle bridge, the limiting protrusion and the limiting groove cooperate to effectively restrict the rotation or movement of the middle bridge, thereby ensuring the stability of the middle bridge position and helping to ensure assembly accuracy and assembly efficiency.

[0020] This application further specifies that a limiting protrusion is formed at the bottom of the pressure head; Also includes: The hinge assembly is connected to the bottom end of the pressure rod and the top end of the pressure head, respectively; Multiple locking components are installed on the pressure head and can press against the top of the middle bridge to adjust the position of the middle bridge.

[0021] By adopting the above technical solution, when the pressure head is pressed down with the pressure rod, the limiting groove, limiting protrusion, and pressure head deflect at a certain angle to cooperate with the limiting groove, thereby initially restricting the position of the middle bridge. Then, multiple locking components are used to fine-tune the position of the middle bridge, further restricting its position. This further improves the assembly accuracy.

[0022] This application further includes: Multiple elastic pressure components are installed on the pressure head, and their bottom ends can press against the top of the middle bridge. Multiple locking components are installed on the pressure head and can press against the top of the middle bridge to adjust the position of the middle bridge.

[0023] By adopting the above technical solution, multiple elastic pressing components are used to initially restrict the position of the middle bridge, and then multiple locking components are used to fine-tune the position of the middle bridge, thus restricting its position again. In this way, the assembly accuracy is further improved.

[0024] In summary, the beneficial technical effects of this application are as follows: 1. The second actuator drives the pressure rod to rotate and move downwards, causing the pressure head to rotate and move downwards, thereby pressing the bottom end of the pressure head against the top of the middle bridge. Then, the first actuator drives the rotating seat to rotate 90° counterclockwise, and then installs screws from above to connect one end of the middle bridge to one side of the air outlet. Afterwards, the first actuator drives the rotating seat to rotate 180° clockwise, and then installs screws from above to connect the other end of the middle bridge to the other side of the air outlet. Afterwards, the first actuator drives the rotating seat to rotate 90° counterclockwise. Then, the second actuator drives the pressure rod to rotate and move upwards, causing the pressure head to rotate and move upwards, thereby disengaging the pressure head from the middle bridge. Compared to relying solely on manual labor, this assembly method assists in the manual assembly of the air outlet and the middle bridge, improving assembly efficiency. During assembly, the middle bridge does not rotate or move relative to the air outlet, maintaining a relatively stable position, thus improving assembly accuracy and preventing deformation and tilting of the middle bridge. Furthermore, because the pressure rod is rotatable, when it reaches directly above the air outlet, it is positioned horizontally to prevent other structures at the top of the air outlet from interfering with the descent of the pressure rod and pressure head, ensuring effective pressure. This also prevents the pressure rod from obstructing the opposite sides of the air outlet, facilitating screw installation by the operator. Once the pressure head detaches from the middle bridge, the pressure rod and pressure head can avoid obstructing the air outlet and middle bridge, making it easy to place and remove the air outlet and middle bridge.

[0025] 2. The first limiting component is used to limit the rotation amplitude when the rotating seat rotates clockwise, and the second limiting component is used to limit the rotation amplitude when the rotating seat rotates counterclockwise.

[0026] 3. When the bottom end of the pressure head presses against the top end of the middle bridge, the limiting protrusion on the pressure head cooperates with the limiting groove, which can effectively restrict the rotation or movement of the middle bridge, thereby ensuring the stability of the middle bridge position and helping to ensure assembly accuracy and assembly efficiency.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0030] Reference Figure 1 , Figure 2 and Figure 3This application discloses a middle bridge and air outlet assembly device, including a frame 110, a rotating base 120, a first driver 130, a pressure rod 140, a pressure head 150, and a second driver 160. The rotating base 120 is rotatably mounted on the top of the frame 110, and its top surface supports the air outlet 210. The first driver 130 is mounted on the top of the frame 110, and its output end is connected to one end of the rotating base 120 to drive the rotating base 120 to rotate. The pressure rod 140 is rotatable and can move up and down. The pressure head 150 is mounted on the bottom of one end of the pressure rod 140, and can rotate with the pressure rod 140 and move up and down with the pressure rod 140, so that the bottom end of the pressure head 150 presses against or disengages from the top of the middle bridge 220. The second driver 160 is mounted on the top of the rotating base 120, and its output end is connected to the end of the pressure rod 140 away from the pressure head 150, to drive the pressure rod 140 to rotate and move up and down. When the second actuator 160 drives the pressure rod 140 to rotate and move downward, the pressure head 150 rotates and moves downward with the pressure rod 140 to press the middle bridge 220 against the center of the top of the air outlet 210. First, the air outlet 210 of the car air conditioner is placed on the top surface of the rotating seat 120. Then, the middle bridge 220 is placed in the middle position of the top of the air outlet 210. Next, the second actuator 160 drives the pressure rod 140 to rotate and move downward, so that the pressure head 150 rotates and moves downward, thereby causing the bottom end of the pressure head 150 to press against the top of the middle bridge 220. Then, the first actuator 130 drives the rotating seat 120 to rotate 90° counterclockwise (e.g., Figure 2 As shown), during this process, the pressure rod 140, pressure head 150, and second actuator 160 rotate with the rotating base 120. Next, screws are installed from above to connect one end of the middle bridge 220 to one side of the air outlet 210. Afterwards, the first actuator 130 drives the rotating base 120 to rotate 180° clockwise (as shown). Figure 3As shown in the diagram, during this process, the pressure rod 140, pressure head 150, and second actuator 160 rotate with the rotating base 120. Next, screws are installed from above to connect the other end of the middle bridge 220 to the other side of the air outlet 210. Then, the first actuator 130 drives the rotating base 120 to rotate 90° counterclockwise. Then, the second actuator 160 drives the pressure rod 140 to rotate and move upward, causing the pressure head 150 to rotate and move upward, thereby disengaging the pressure head 150 from the middle bridge 220. Finally, the air outlet 210 and the middle bridge 220 are disengaged from the rotating base. Compared to relying solely on manual labor, this method assists in the manual assembly of the air outlet 210 and the middle bridge 220, improving assembly efficiency. During assembly, the middle bridge 220 does not rotate or move relative to the air outlet 210, maintaining a relatively stable position, thus improving assembly accuracy and preventing deformation and tilting of the middle bridge 220. Furthermore, because the pressure rod 140 is rotatable, when it reaches directly above the air outlet 210, it is positioned horizontally. This prevents other structures at the top of the air outlet 210 from interfering with the descent of the pressure rod 140 and the pressure head 150, ensuring a strong pressure effect. It also prevents the pressure rod 140 from obstructing the opposite sides of the air outlet 210, facilitating the installation of screws by the operator. After the pressure head 150 disengages from the middle bridge 220, the pressure rod 140 and the pressure head 150 can avoid obstructing the air outlet 210 and the middle bridge 220, making it easier to place and remove the air outlet 210 and the middle bridge 220.

[0031] Preferably, the first driver 130 is a pneumatic motor, using compressed air as the working medium, which is readily available. By precisely controlling the input and output of compressed air, the rotation angle of the pneumatic motor's output end can be precisely controlled, which helps improve assembly accuracy. Of course, the first driver 130 can also be a stepper motor, which is less expensive. The first driver 130 can also be a servo motor, which offers higher precision.

[0032] Preferably, the second actuator 160 is a lifting rotary cylinder with rotation and lifting functions, using compressed air as the working medium, which is readily available. By precisely controlling the input and output of compressed air, the lifting amplitude and rotation angle of the lifting rotary cylinder can be precisely controlled, which helps to ensure the clamping effect.

[0033] Preferably, the output end of the second driver 160 is fixedly connected to one end of the transmission rod 161. The other end of the transmission rod 161 is fixedly connected to the end of the pressure rod 140 away from the pressure head 150. The length direction of the transmission rod 161 is perpendicular to the length direction of the pressure rod 140, which is beneficial for the pressure rod 140 to be positioned laterally when it reaches directly above the air outlet 210.

[0034] In one embodiment, the middle bridge and air outlet assembly device further includes a first limiting component 171. The first limiting component 171 is installed on one side of the top of the frame 110 and is used to limit the rotation range of the rotating seat 120 when it rotates clockwise.

[0035] In another embodiment, the middle bridge and air outlet assembly device further includes a second limiting component 172. The second limiting component 172 is mounted on the other side of the top of the frame 110 and is used to limit the rotation range of the rotating seat 120 when it rotates counterclockwise.

[0036] In yet another embodiment, reference is made to... Figure 1 The assembly device for the middle bridge and the air outlet also includes a first limiting component 171 and a second limiting component 172. The first limiting component 171 is installed on one side of the top of the frame 110 and is used to limit the rotation range of the rotating seat 120 when it rotates clockwise. The second limiting component 172 is installed on the other side of the top of the frame 110 and is used to limit the rotation range of the rotating seat 120 when it rotates counterclockwise.

[0037] Preferably, there are two first limiting components 171, which are installed on the same side of the top of the frame 110.

[0038] Preferably, there are two second limiting components 172, which are installed on the same side of the top of the frame 110.

[0039] Reference Figure 3 and Figure 4 In one embodiment, the first limiting component 171 includes a first limiting seat 1711 and a buffer 1712. The first limiting seat 1711 is mounted on the top of the frame 110. The buffer 1712 is mounted on the first limiting seat 1711. When the rotating seat 120 rotates, it can press against the top of the buffer 1712 to limit the rotation of the rotating seat 120. The buffer 1712 can absorb and mitigate the impact force of the rotating seat 120, reduce the degree of damage caused by the impact, and extend its service life. The structure of the second limiting component 172 is the same as that of the first limiting component 171.

[0040] Preferably, the first limiting seat 1711 is detachably mounted to the top of the frame 110 by bolts, so as to facilitate the disassembly, replacement and installation of the first limiting assembly 171 and the second limiting assembly 172.

[0041] Preferably, the buffer 1712 can be a spring buffer 1712, which has a simple structure and low cost. The buffer 1712 can also be a hydraulic buffer 1712, which provides smooth buffering, no rebound, long service life, and low maintenance requirements. The buffer 1712 can also be a polyurethane buffer 1712, which is lightweight, easy to install, and absorbs impact energy by means of material deformation.

[0042] Reference Figure 1 A second limiting seat 121 is formed on the top surface of the rotating base. The top surface of the second limiting seat 121 is adapted to the bottom surface of the air outlet 210. The second limiting seat 121 can be detachably connected to the bottom end of the air outlet 210. This facilitates the installation and removal of the air outlet 210. When the air outlet 210 is installed on the second limiting seat 121, the second limiting seat 121 can restrict the movement of the air outlet 210 within the plane of the second limiting seat 121, improving the stability of the position of the air outlet 210, and thus helping to ensure assembly accuracy.

[0043] Preferably, the second limiting seat 121 and the air outlet 210 can be detachably connected by means of snap-fit ​​or screw connection.

[0044] Reference Figure 1 The assembly device for the middle bridge and air outlet also includes a solenoid valve, an air inlet pipe, a first air supply pipe, a first air return pipe, a second air supply pipe, a second air return pipe, a position detection sensor 173, a controller 174, and multiple operation buttons. One end of the air inlet pipe is connected to an air source, and the other end is connected to the solenoid valve. One end of the first air supply pipe is connected to the solenoid valve, and the other end is connected to the first actuator 130, used to supply compressed gas to the first actuator 130. One end of the first air return pipe is connected to the first actuator 130, and the other end is connected to the solenoid valve, used to output compressed gas from the first actuator 130. One end of the second air supply pipe is connected to the solenoid valve, and the other end is connected to the second actuator 160, used to supply compressed gas to the second actuator 160. One end of the second air return pipe is connected to the second actuator 160, and the other end is connected to the solenoid valve, used to output compressed gas from the second actuator 160. The position detection sensor 173 is fixedly installed on the top of the rotating base, used to detect whether the air outlet 210 is in position, and can send the detection signal to the controller 174. The controller 174 is mounted on the rack 110 and is electrically connected to the first driver 130, the second driver 160, the position detection sensor 173, and the solenoid valve, respectively, to control their operation. Multiple operation buttons are mounted on the top of the rack 110 and are electrically connected to the controller 174, so that the operator can control the first driver 130 and the second driver 160 to operate.

[0045] Preferably, there are two position detection sensors 173, which are fixedly installed at opposite ends of the top surface of the rotating base to improve detection accuracy. Simultaneously, they enable one-to-one detection and verification.

[0046] Preferably, each position detection sensor 173 can be a magnetoelectric position sensor, photoelectric position sensor, ultrasonic position sensor, Hall position sensor, inductive position sensor, laser position sensor, or contact plate position sensor, etc.

[0047] Reference Figure 3 and Figure 4 The assembly of the middle bridge and air outlet also includes two support seats 181 and two adapter plates 182. The two support seats 181 are fixedly installed at opposite ends of the top of the frame 110. One end of the rotating seat 120 is rotatably connected to one of the support seats 181 via one of the adapter plates 182, and the other end is fixedly connected to the output end of the first driver 130 via the other adapter plate 182. The fixed end of the first driver 130 is fixedly connected to the other support seat 181. Two limiting blocks 1821 are formed at the top of each adapter plate 182. One limiting block 1821 cooperates with the buffer 1712 of the first limiting component 171 to limit the rotation amplitude of the rotating seat 120 when rotating clockwise. The other limiting block 1821 cooperates with the buffer 1712 of the second limiting component 172 to limit the rotation amplitude of the rotating seat 120 when rotating counterclockwise.

[0048] Reference Figure 5 In one embodiment, the surface of the pressure head 150 is perpendicular to the length direction of the pressure rod 140. A limiting protrusion 151 is formed at the bottom of the pressure head 150, which matches the limiting groove at the top of the middle bridge 220. When the bottom end of the pressure head 150 presses against the top end of the middle bridge 220, the limiting protrusion 151 and the limiting groove cooperate to effectively restrict the rotation or movement of the middle bridge 220, thereby ensuring the stability of the middle bridge 220's position and facilitating assembly accuracy and efficiency. The pressure head 150 is made of a flexible material such as rubber or silicone to prevent damage to the middle bridge 220. The top end of the pressure head 150 and the bottom end of the pressure rod 140 are detachably connected by bolts to facilitate the assembly, use, disassembly, and replacement of the pressure head 150 and the pressure rod 140.

[0049] Reference Figure 6 , Figure 7 and Figure 8In another embodiment, the surface of the pressure head 150 is perpendicular to the length direction of the pressure rod 140. A limiting protrusion 151 is formed at the bottom of the pressure head 150, which is adapted to the limiting groove at the top of the middle bridge 220. When the bottom end of the pressure head 150 presses against the top end of the middle bridge 220, the limiting protrusion 151 and the limiting groove cooperate to effectively restrict the rotation or movement of the middle bridge 220, thereby ensuring the stability of the position of the middle bridge 220 and helping to ensure assembly accuracy and efficiency. The middle bridge and air outlet assembly device also includes a hinge assembly 191 and a locking assembly 192. The hinge assembly 191 is connected to the bottom end of the pressure rod 140 and the top end of the pressure head 150, respectively. Multiple locking assemblies 192 are respectively installed on the pressure head 150 and can press against the top end of the middle bridge 220 to accurately adjust the position of the middle bridge 220. It should be noted that when the middle bridge 220 is placed at the top of the air outlet 210, its position may have shifted. The pressure head 150 is made of a rigid material such as copper or stainless steel. When the pressure head 150 is pressed down with the pressure rod 140, the limiting groove, the limiting protrusion 151, and the pressure head 150 are deflected at a certain angle to cooperate with the limiting groove, thereby initially restricting the position of the middle bridge 220. Then, the position of the middle bridge 220 is finely adjusted by multiple locking components 192, so that the limiting protrusion 151 faces directly downwards, and the position of the middle bridge 220 is restricted again. In this way, the assembly accuracy is further improved.

[0050] Preferably, such as Figure 7 and Figure 8 As shown, the hinge assembly 191 includes a first connecting rod 1911, a spherical groove 1912, a connecting ball 1913, and a second connecting rod 1914. The first connecting rod 1911 is fixedly connected to the bottom end of the pressure rod 140, and its bottom end is fixedly connected to the protruding side of the spherical groove 1912. The connecting ball 1913 is rotatably mounted within the spherical groove 1912. The top end of the second connecting rod 1914 is fixedly connected to the connecting ball 1913, and its bottom end is fixedly connected to the top end of the pressure head 150. Thus, when the pressure head 150 is pressed down with the pressure rod 140, the limiting groove, the limiting protrusion 151, and the pressure head 150 can be deflected relatively flexibly to cooperate with the limiting groove, thereby initially restricting the position of the middle bridge 220.

[0051] Preferably, such as Figure 7 and Figure 8As shown, there are two locking assemblies 192, respectively installed at both ends of the pressure head 150. Each locking assembly 192 includes a bushing 1921, a locking rod 1922, a first tightening spring 1923, a tightening block 1924, two tightening balls 1925, a tightening ring 1926, a handle 1927, and two ball bearings 1928. The bushing 1921 is fixedly installed inside the pressure head 150. An internal thread is formed on the upper inner wall of the bushing 1921. The lower part of the locking rod 1922 is inserted into the bushing 1921. An external thread matching the internal thread is formed on the lower outer wall of the locking rod 1922. The tightening block 1924 is movably installed in the bushing 1921. The top end of the first tightening spring 1923 abuts against the bottom end of the locking rod 1922, and the bottom end abuts against the top end of the tightening block 1924. The lower part of the clamping block 1924 has a circumferentially inclined surface. Two clamping balls 1925 are both disposed within the bushing 1921 and located below the clamping block 1924. On the opposite side walls of the lower part of the bushing 1921, clearance holes 19211 are formed for the clamping balls 1925 on the corresponding sides to pass through and exit. The clamping ring 1926 is slidably fitted onto the bottom end of the bushing 1921. Relief grooves 19261 are formed on the inner walls of the opposite sides of the clamping ring 1926. The handle 1927 is fixedly mounted on the top of the locking rod 1922. When the human hand drives the handle 1927 to rotate, it drives the locking rod 1922 to rotate. This, in turn, causes the first tightening spring 1923 to move the tightening block 1924 downwards. The inclined surface at the bottom of the tightening block 1924 drives two tightening balls 1925 through the corresponding clearance holes 19211 and into the corresponding clearance grooves 19261 of the tightening ring 1926. This causes the tightening ring 1926 to tend to move downwards, resulting in a tight fit between the bottom end of the tightening ring 1926 and the top end of the middle bridge 220. The two locking components 192 achieve precise adjustment of the middle bridge 220's position and further restrict its movement or rotation. To ensure the tightening ring 1926 can move smoothly up and down along the axial direction of the bushing 1921 and to prevent the tightening ring 1926 from spontaneously detaching from the bushing 1921... Sliding grooves are formed on the outer walls of opposite sides of the lower part of the bushing 1921, and rolling grooves are formed on the inner walls of opposite sides of the clamping ring 1926. One ball bearing 1928 is installed in one of the sliding grooves and rolling grooves on one side. The other ball bearing 1928 is installed in the sliding groove and rolling groove on the other side.

[0052] Reference Figure 9 , Figure 10 and Figure 11The assembly device for the middle bridge and air outlet also includes multiple elastic pressing members 193 and multiple locking components 192. The multiple elastic pressing members 193 are respectively mounted on the pressure head 150, with their bottom ends capable of pressing against the top of the middle bridge 220. When the pressure head 150 moves downward with the pressure rod 140, the bottom ends of the multiple elastic pressing members 193 press against the top of the middle bridge 220. Since the axial length of each elastic pressing member 193 can change, the multiple elastic pressing members adaptively adjust their axial length according to the structure of the top of the middle bridge 220. The multiple locking components 192 are respectively mounted on the pressure head 150 and can press against the top of the middle bridge 220. It should be noted that when the middle bridge 220 is placed at the top of the air outlet 210, its position may have shifted. The multiple elastic pressing members 193 initially restrict the position of the middle bridge 220, and then the multiple locking components 192 fine-tune the position of the middle bridge 220, further restricting its position. This further improves assembly precision.

[0053] Preferably, such as Figure 10 and Figure 11 As shown, the bottom end of the pressure head 150 has multiple mounting slots 152. These mounting slots 152 are arranged in a rectangular array, each corresponding to one of the multiple elastic abutment members 193. Each elastic abutment member 193 includes a push rod 1931 and a second tightening spring 1932. The second tightening spring 1932 passes through the mounting slot 152, its top end fixedly connected to the top end of the mounting slot 152, and its bottom end fixedly connected to the bottom end of the push rod 1931. When the multiple elastic abutment members 193 move downwards with the pressure head 150, each elastic abutment member 193 adaptively adjusts its length extending out of the mounting slot 152 to initially restrict the position of the middle bridge 220.

[0054] Preferably, such as Figure 10 and Figure 11As shown, there are three locking components 192 arranged in a triangular pattern. Each locking component 192 includes a bushing 1921, a locking rod 1922, a first tightening spring 1923, a tightening block 1924, two tightening balls 1925, a tightening ring 1926, a handle 1927, and two ball bearings 1928. The bushing 1921 is fixedly installed inside the pressure head 150. An internal thread is formed on the upper inner wall of the bushing 1921. The lower part of the locking rod 1922 is inserted into the bushing 1921. An external thread matching the internal thread is formed on the lower outer wall of the locking rod 1922. The tightening block 1924 is movably installed in the bushing 1921. The top end of the first tightening spring 1923 abuts against the bottom end of the locking rod 1922, and the bottom end abuts against the top end of the tightening block 1924. The lower part of the clamping block 1924 has a circumferentially inclined surface. Two clamping balls 1925 are both disposed within the bushing 1921 and located below the clamping block 1924. On the opposite side walls of the lower part of the bushing 1921, clearance holes 19211 are formed for the clamping balls 1925 on the corresponding sides to pass through and exit. The clamping ring 1926 is slidably fitted onto the bottom end of the bushing 1921. Relief grooves 19261 are formed on the inner walls of the opposite sides of the clamping ring 1926. The handle 1927 is fixedly mounted on the top of the locking rod 1922. When the human hand drives the handle 1927 to rotate, it drives the locking rod 1922 to rotate. This, in turn, causes the first tightening spring 1923 to move the tightening block 1924 downwards. The inclined surface at the bottom of the tightening block 1924 drives two tightening balls 1925 through the corresponding clearance holes 19211 to abut against the corresponding clearance groove 19261 of the tightening ring 1926. This causes the tightening ring 1926 to tend to move downwards, resulting in a tight fit between the bottom end of the tightening ring 1926 and the top end of the middle bridge 220. The three locking components 192 achieve precise three-point adjustment of the middle bridge 220's position and further restrict the movement or rotation of the middle bridge 220. To ensure the tightening ring 1926 can move smoothly up and down along the axial direction of the bushing 1921 and to prevent the tightening ring 1926 from spontaneously detaching from the bushing 1921... Sliding grooves are formed on the outer walls of opposite sides of the lower part of the bushing 1921, and rolling grooves are formed on the inner walls of opposite sides of the clamping ring 1926. One ball bearing 1928 is installed in one of the sliding grooves and rolling grooves on one side. The other ball bearing 1928 is installed in the sliding groove and rolling groove on the other side.

[0055] The implementation principle of this embodiment is as follows: First, the air outlet 210 of the car air conditioner is placed on the top surface of the rotating base 120. Then, the middle bridge 220 is placed at the middle position of the top of the air outlet 210. Next, the second driver 160 drives the pressure rod 140 to rotate and move downward, so that the pressure head 150 rotates and moves downward, thereby causing the bottom end of the pressure head 150 to press against the top of the middle bridge 220. Then, the first driver 130 drives the rotating base 120 to rotate 90° counterclockwise. During this process, the pressure rod 140, the pressure head 150, and the second driver 160 rotate with the rotating base 120. Next, screws are installed from above to connect one end of the middle bridge 220 to one side of the air outlet 210. Afterward, the first driver 130 drives the rotating base 120 to rotate 180° clockwise. During this process, the pressure rod 140, the pressure head 150, and the second driver 160 rotate with the rotating base 120. Next, screws are installed from above to connect the other end of the middle bridge 220 to the other side of the air outlet 210. Then, the first actuator 130 drives the rotating base 120 to rotate 90° counterclockwise. Then, the second actuator 160 drives the pressure rod 140 to rotate and move upward, causing the pressure head 150 to rotate and move upward, thereby disengaging the pressure head 150 from the middle bridge 220. Finally, the air outlet 210 and the middle bridge 220 are disengaged from the rotating base. Compared to relying solely on manual labor, this assembly method assists in the manual assembly of the air outlet 210 and the middle bridge 220, improving assembly efficiency. During assembly, the middle bridge 220 does not rotate or move relative to the air outlet 210, maintaining a relatively stable position, thus improving assembly accuracy and preventing deformation and tilting of the middle bridge 220. Furthermore, because the pressure rod 140 is rotatable, when it reaches directly above the air outlet 210, it is positioned horizontally. This prevents other structures at the top of the air outlet 210 from interfering with the descent of the pressure rod 140 and the pressure block, ensuring a strong pressure effect. It also prevents the pressure rod 140 from obstructing the opposite sides of the air outlet 210, facilitating the installation of screws by the operator. When the pressure head 150 disengages from the middle bridge 220, the pressure rod 140 and pressure head 150 can avoid obstructing the air outlet 210 and the middle bridge 220, making it easier to place and remove the air outlet 210 and the middle bridge 220.
