Description

Technical Field

[0002] Car speakers are double-conical, two-way, subwoofer-type external speakers commonly found on the front doors of cars. Car speakers are the common name for car speakers, and are an indispensable and important device in a sound system. As the only device that converts electrical energy into "sound energy", the quality and characteristics of car speakers play a decisive role in the sound quality of the entire sound system. Due to the particularity of cars, it is impossible to install universal speakers like home theaters in cars. Instead, each car speaker is directly installed on the car. A high-end car can even be equipped with more than ten car speakers.

[0003] In order to adapt to the different designs of vehicles, there are many types of vehicle speakers, and there are many specifications, such as round, square, diamond, etc., and in the process of processing vehicle speakers, it is necessary to weld and connect the connection parts between the voice coil and the lead, the connection parts between the diaphragm and the voice coil, the connection parts between the basin and the terminal, and the connection parts between the crossover and the speaker unit, and perform auxiliary positioning and fixing to help the welding operation. The existing vehicle speaker welding positioning device has a single functionality and only realizes the positioning function, and cannot adapt to speakers of various specifications. When replacing vehicle speakers of different models for welding, it is cumbersome to readjust the positioning structure, the manual operation is cumbersome, and detection assistance cannot be performed. Based on this, a multifunctional positioning device for vehicle speaker welding is proposed. Summary of the invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the device is in use, the sealing nut is installed into the top of the positioning adjustment mechanism, and the vehicle-mounted horn to be positioned is placed on the top of the support plate. At this time, pressure is applied to the horn, and the positioning adjustment mechanism is squeezed downward. After the deformation caused by the squeezing of the conical soft suction cup and the silicone column, the gas inside the conical soft suction cup and the silicone column is discharged, so that the inner sealing column is adsorbed by the air pressure to maintain the position, thereby forming a raised positioning adjustment mechanism and a flat positioning adjustment mechanism around the horn to form a limiting shape surrounding the horn, thereby playing a role in positioning vehicle-mounted horns of different shapes, thereby achieving the effect of plane movement adjustment of different positions, facilitating welding auxiliary operations for different operation needs of the vehicle-mounted horn, increasing the multi-functional effect, and increasing the use efficiency of the structure, convenient adjustment, and high adaptability;

[0018] 2. In this scheme, when the electric telescopic rod is extended or retracted, the convex slide plate can be driven to extend and slide inside the concave outer plate, and the convex position of the convex slide plate and the corresponding positions of the concave outer plate form a sliding support effect. When the convex slide plate and the concave outer plate are extended or retracted, the distance between them is shortened, which causes the rotating support mechanism to move relative to each other, and the force is applied to the inverted T-shaped arc slider. Through the rolling movement of the rolling ball and the movement of the inner side of the T-shaped arc slide groove, and through the rotation effect of the movable turntable, the mobile rail mechanism is horizontally mounted at the semicircular position on the top of the support plate to move, thereby ensuring the smooth operation of the mobile welding mechanism and not hindering the movement trajectory of the mobile welding mechanism.

[0019] 3. This solution can cooperate with the clamping and positioning operations of the position, and can assist in adapting to the positioning operations of vehicle-mounted speakers of different specifications, facilitating clamping and positioning to meet the positioning adjustment requirements for different shapes. The dense distribution dimensions of the positioning adjustment mechanism can adapt to the shape positioning of finished and semi-finished products of various vehicle-mounted speakers, facilitating adjustment.

Detailed implementation manner

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 14, the present invention provides a technical solution: a multi-functional positioning device for vehicle-mounted horn welding, including a support plate 1, a telescopic positioning mechanism 6, a positioning detection mechanism 9 and a plug nut 10. A cavity 101 is provided inside the support plate 1. A T-shaped arc chute 2 is provided on the outer side of the top of the support plate 1. A T-shaped arc slider 3 is slidably installed inside the T-shaped arc chute 2. A support plate 301 is fixedly installed on the top of the T-shaped arc slider 3. A rotating support mechanism 4 is installed on the top of the support plate 301. A moving rail mechanism 5 is installed on the top of the rotating support mechanism 4. A moving welding mechanism 11 is movably installed on the top of the moving rail mechanism 5. A number of positioning adjustment mechanisms 7 are installed inside the cavity 101. The bottom of the cavity 101 communicates with a pressure adjustment mechanism 8.

[0037] The positioning adjustment mechanism 7 includes an outer seal sleeve 701. The outer seal sleeve 701 is fixedly penetrated through the support plate 1 and communicated to the inside of the cavity 101. An inner seal column 702 is movably sleeved inside the outer seal sleeve 701. A threaded groove 703 is provided inside the top end of the inner seal column 702. A sealing ring 707 is movably sleeved on the outer side of the inner seal column 702 through a groove. A silica gel column 704 is fixedly installed at the bottom of the inner seal column 702. A conical soft suction cup 705 is fixedly sleeved on the outer side of the bottom end of the silica gel column 704. A number of air holes 706 are provided inside the conical soft suction cup 705.

[0038] A threaded column 1002 is fixedly installed at the bottom of the plug nut 10. An internal hexagonal groove 1001 is provided on the top of the plug nut 10. A sealing gasket 1003 is fixedly installed at the bottom of the plug nut 10.

[0039] Working principle of the above technical solution: During use, the plugging nut 10 is installed on the top of the positioning and adjusting mechanism 7, and the vehicle-mounted speaker to be positioned is placed on the top of the support plate 1. At this time, pressure is applied to the speaker, squeezing the positioning and adjusting mechanism 7 to move downward. The conical soft suction cup 705 deforms under pressure, causing the silicone column 704 to contact the bottom of the inner cavity of the cavity 101. Then, the air pressure adjusting mechanism 8 is pushed. At this time, the air pressure inside the cavity 101 increases, prompting the inner sealing column 702 except for the part pressed by the speaker. At this time, air flows through the air permeation holes 706 into the conical soft suction cup 705 and the inside of the conical soft suction cup 705, pushing the inner sealing column 702 to rise inside the outer sealing sleeve 701, and remaining relatively stable under the sealing and squeezing action of the sealing ring 707 and the action of the air flow. For the positioning and adjusting mechanism 7 pressed by the speaker, at this time, due to the deformation caused by the extrusion of the conical soft suction cup 705 and the silicone column 704, part of the gas inside the conical soft suction cup 705 and the silicone column 704 is discharged. Thus, the inner sealing column 702 is held in position by the air pressure adsorption effect, forming a limiting shape that encloses the speaker with the raised positioning and adjusting mechanism 7 and the flat positioning and adjusting mechanism 7 around the speaker, thereby playing a role in positioning vehicle-mounted speakers of different shapes. Then, by rotating the support mechanism 4 to expand and contract, and adjusting the telescopic positioning mechanism 6 to adjust the position of different parts of the speaker, auxiliary operations are carried out. Then, the mobile welding mechanism 11 moves on the top of the mobile rail mechanism 5, and the mobile rail mechanism 5 itself expands and contracts to cooperate with the adjustment of the position of the mobile welding mechanism 11, thereby achieving the effect of adjusting the movement on different position planes, facilitating the welding auxiliary operations for different operation requirements of the vehicle-mounted speaker, increasing the multi-functional effect, and increasing the use efficiency of the structure. The adjustment is convenient and the adaptability is high.

[0040] In another embodiment, as Figures 1 - 9 shown, both the T-shaped arc chute 2 and the T-shaped arc slider 3 are inverted T-shaped. The bottom of the support plate 301 is in sliding contact with the top of the support plate 1. A number of bolts are threadedly connected inside the support plate 301. A number of rolling beads 302 are installed on both sides of the T-shaped arc slider 3 through ball grooves. The rolling beads 302 are linearly symmetrically distributed on both sides of the T-shaped arc slider 3, and the outer sides of the rolling beads 302 are in rolling contact with the inner side of the T-shaped arc chute 2.

[0041] The bottom of the T-shaped arc slider 3 contacts the inner cavity of the T-shaped arc chute 2. The contact surface is a smooth surface, and grease is applied to reduce the friction coefficient. The rolling beads 302 are used to reduce the lateral extrusion shear force on the contact surface between the T-shaped arc slider 3 and the T-shaped arc chute 2. When a force is applied to the T-shaped arc slider 3, the T-shaped arc slider 3 can slide unobstructed inside the T-shaped arc chute 2. The screws of the support plate 301 can be tightened to squeeze the top of the support plate 1, so as to assist in positioning the T-shaped arc slider 3 at a fixed position, thereby adjusting between movement and fixation, and assisting in the movement adjustment of the rotating support mechanism 4 and the moving rail mechanism 5.

[0042] In another embodiment, as Figures 1 - 9 shown, the positioning and adjusting mechanisms 7 are densely distributed on the surface and inside the cavity 101 of the support plate 1. A number of positioning and adjusting mechanisms 7 are evenly and regularly arranged in the area of the support plate 1 at a small spacing, forming a tight and orderly layout array.

[0043] The positioning and adjusting mechanisms 7 are evenly distributed in a circle inside the support plate 1, and on the effective bearing surface of the circular base support plate 1, the positioning and adjusting mechanisms 7 are arranged in a densely packed form. Their distribution density is optimized to meet the positioning and adjusting requirements for different shapes. The densely distributed size of the positioning and adjusting mechanisms 7 can adapt to the shape positioning of finished and semi-finished products of various vehicle-mounted speakers, facilitating adjustment.

[0044] In another embodiment, as Figures 1 - 13 shown, both the inner sealing column 702 and the silica gel column 704 are cylindrical hollow structures. The specifications of the threaded column 1002 and the plugging nut 10 are adapted to the specifications of the threaded groove 703 and the inner sealing column 702. A silica gel ring 708 is fixedly sleeved inside the conical soft suction cup 705. The air pressure adjusting mechanism 8 includes an air duct 801 and an adjusting piston column 802. The air duct 801 communicates with the inside of the cavity 101, and the adjusting piston column 802 is movably sleeved inside the air duct 801.

[0045] The hollow channels of the inner sealing column 702 and the silica gel column 704 are air flow channels, which are also the channels for installing the plugging nut 10 in cooperation with the threaded groove 703. The threaded column 1002 is screwed into the threaded groove 703, and then the top of the inner sealing column 702 is extruded by the sealing gasket 1003 to seal the connection part to avoid air leakage. When the silica gel column 704, the conical soft suction cup 705 and the silica gel ring 708 are extruded to the bottom of the inner cavity of the cavity 101, deformation occurs to discharge the internal air pressure, so as to achieve the suction effect of the suction cup, and then stabilize the position. After the inner sealing column 702 and the plugging nut 10 are installed, the lowered position is set to be the same as the size of the outer sealing sleeve 701, so as to keep the top of the support plate 1 flat. To lift the positioning and adjusting mechanism 7 at the pressing position, just unscrew the plugging nut 10 to release the plugging and limiting of the inner sealing column 702 and the threaded groove 703, and the air is released. When the adjusting piston column 802 is pushed inside the air guide tube 801, the adjusting piston column 802 pushes out the air pressure inside the air guide tube 801, so as to increase the pressure inside the cavity 101. Then the air flows into the inner side of the conical soft suction cup 705 through the gap of the air permeable hole 706, and then through the hollow channels of the silica gel column 704 and the inner sealing column 702, the plugging and sealing position of the plugging nut 10 is lifted, so as to realize the limiting function outside the pressing position and facilitate adjustment.

[0046] In another embodiment, as Figures 1 - 9 shown, the rotating support mechanism 4 includes two movable turntables 401. The bottoms of the two movable turntables 401 are fixedly installed on the top of the support plate 301. Electric telescopic rods 402 are rotatably installed on the inner sides of the tops of the two movable turntables 401. The output ends of the two electric telescopic rods 402 are fixedly installed with T-shaped mounting brackets 404. Side mounting plates 403 are fixedly installed on both sides of the two electric telescopic rods 402.

[0047] The movable turntable 401 is a structural component with rotational support, such as a rolling turntable and a bearing support, used to realize the rotational support of the electric telescopic rod 402, so as to reduce the rotational effect generated by the telescopic movement of the moving rail mechanism 5 on the T-shaped arc slider 3, thereby ensuring the smooth operation of the structure. The inverted T structure of the T-shaped mounting bracket 404 can fixedly support the end faces and bottom surfaces of the convex slide plate 501 and the concave outer plate 502, increase the stress intensity of the convex slide plate 501 and the concave outer plate 502, and increase the relative stability of the structure, so as to ensure the smooth operation of the connection structure.

[0048] In another embodiment, as Figures 1 - 11As shown in the figure, the moving rail mechanism 5 includes a convex slide plate 501 and a concave outer plate 502. The convex slide plate 501 is movably sleeved inside the concave outer plate 502. The opposite ends of the convex slide plate 501 and the concave outer plate 502 are fixedly installed on the opposite sides of the top of the T-shaped mounting bracket 404. A number of long rubber pads 505 are fixedly installed on the top of the convex slide plate 501. A number of short rubber pads 504 are fixedly installed on both sides of the top of the concave outer plate 502. An electric control telescopic rod 503 is sleeved inside the concave outer plate 502. The fixed end of the electric control telescopic rod 503 is fixedly installed on the inner wall of one end of the concave outer plate 502. The output end of the electric control telescopic rod 503 is fixedly installed on one side of the convex slide plate 501. The convex slide plate 501 is convex, and the specifications and dimensions of the concave outer plate 502 are adapted to those of the convex slide plate 501. There is a gap on the opposite sides of the tops of the convex slide plate 501 and the concave outer plate 502.

[0049] When the electric control telescopic rod 503 expands and contracts, it can drive the convex slide plate 501 to expand and contract and slide inside the concave outer plate 502. The two sides of the convex position of the convex slide plate 501 form a sliding support effect with the corresponding positions of the concave outer plate 502. When the convex slide plate 501 and the concave outer plate 502 expand and contract, the distance shortens, prompting the rotation support mechanism 4 to move relatively, and applying this force to the T-shaped arc slider 3. Through the rolling movement of the rolling beads 302 and the movement inside the T-shaped arc chute 2, and through the rotation effect of the movable turntable 401, the moving rail mechanism 5 can move horizontally at the semi-circular position on the top of the support plate 1, thereby changing the position, providing a planar moving position for the moving welding mechanism 11, facilitating auxiliary movement. When assembling, a stop block needs to be set on the top of the support plate 1 to limit the moving position of the T-shaped arc slider 3 within the semi-circular interval of the support plate 1, so as to achieve semi-circular planar movement. The long rubber pads 505 and the short rubber pads 504 are used to increase the friction force on the moving parts of the moving welding mechanism 11, thereby ensuring the smooth operation of the moving welding mechanism 11 and not hindering the movement track of the moving welding mechanism 11.

[0050] In another embodiment, as Figures 1 - 11 shown, the telescopic positioning mechanism 6 includes two outer sliding sleeves 602. Activity hoops 603 are movably sleeved on the outer sides of the two outer sliding sleeves 602. A clamping electric telescopic rod 604 is fixedly installed at the bottom of the activity hoop 603. An arc-shaped positioning clamping plate 605 is fixedly installed at the bottom end of the clamping electric telescopic rod 604. The activity hoop 603 is fixed on the outer side of the outer sliding sleeve 602 through a setscrew. Inner sliding rods 601 are movably sleeved on the inner sides of both ends of the two outer sliding sleeves 602. One end of the inner sliding rod 601 away from the outer sliding sleeve 602 is fixed on the opposite sides of the side mounting plate 403 through bolts.

[0051] When adjusting the positions of the clamping electric telescopic rod 604 and the arc-shaped positioning clamping plate 605, it is only necessary to slide the position of the movable hoop 603 outside the outer sliding sleeve 602 and fix it with a setscrew. When installing, it is fixed by bolts passing through the side mounting plate 403. When the relative position of the rotating support mechanism 4 changes, the movable socket position of the inner sliding rod 601 and the outer sliding sleeve 602, so as to cooperate with the moving rail mechanism 5 for movement. However, the restricted movement range is larger, which is convenient for fixing the top position of the horn.

[0052] In another embodiment, as Figures 3 - 12 shown, the positioning and detecting mechanism 9 includes a hollow disk 901 and a horn terminal 907. A positioning seat 902 is fixedly installed at the top of the hollow disk 901. An audio signal generator terminal block 904 is fixedly installed at the top of the hollow disk 901 by bolts. The output end of the audio signal generator terminal block 904 is electrically connected to two connecting wires 906. The output ends of the two connecting wires 906 are electrically connected to a conductive placement seat 916. A flexible adjustable support frame 903 is fixedly installed at the bottom of the conductive placement seat 916. The flexible adjustable support frame 903 is fixedly installed at the top of the hollow disk 901. Two support sleeves 908 are fixedly sleeved on one side of the top of the hollow disk 901. The bottoms of the two support sleeves 908 communicate with the inside of the hollow disk 901. Two piston rods II 909 are movably sleeved inside the two support sleeves 908. A positioning pin 913 is fixedly installed on one side of the piston rod II 909. Positioning grooves 911 are formed at the tops of the two support sleeves 908. Downward movement grooves 910 are formed on the fronts of the two support sleeves 908. The specification and size of the positioning pin 913 are adapted to the specification and size of the downward movement grooves 910 and the positioning grooves 911. Connecting ropes 915 are fixedly connected to the bottoms of the two support sleeves 908. The other ends of the connecting ropes 915 are fixedly connected to a flexible diaphragm 914. The flexible diaphragm 914 is fixedly sleeved inside the hollow disk 901. The connecting ropes 915 are symmetrically distributed on the top of the flexible diaphragm 914. A silica gel pad 905 is fixedly installed at the bottom of the hollow disk 901. Suction cup holes 912 are formed inside the hollow disk 901 and the silica gel pad 905. The two ends of the suction cup holes 912 communicate with the inside of the hollow disk 901 and the bottom of the silica gel pad 905 respectively. The horn terminal 907 is movably placed inside the conductive placement seat 916.

[0053] When sound detection of the speaker is required, the positioning and detection mechanism 9 is placed on the top of the positioning and adjusting mechanism 7 and the support plate 1. The installation method is the same as that for placing the speaker. Then, press the hollow disc 901 and pull up the piston rod two 909. The piston rod two 909 reduces the pressure inside the hollow disc 901, and pulls the connecting rope 915 through the piston rod two 909, thereby causing the flexible diaphragm 914 to deform, reducing the air pressure inside the hollow disc 901, and then generating an adsorption effect through the silica gel pad 905 and the suction cup holes 912 at the contact positions with the top of the support plate 1 and the plugging nut 10, so as to fix the hollow disc 901 on the top of the support plate 1. Then, rotate the piston rod two 909 to make the positioning pin column 913 disengage from the lower moving groove 910 and rotate to the inside of the positioning groove 911 for support, thereby stabilizing the position of the piston rod two 909, and then playing a role of air pressure fixation. Then, place the speaker inside the positioning seat 902, make the port of the speaker wiring contact with the conductive placement seat 916, and insert the output wire of the audio signal generator into the wiring terminal of the audio signal generator wiring seat 904. Then, the audio signal is transmitted to the conductive placement seat 916 through the connecting wire 906, and then the sound detection of the speaker is carried out, assisting in the detection, and being able to play a certain limiting effect, and being able to cooperate with the telescopic positioning mechanism 6 for stable operation, facilitating multi-faceted operation and welding.

[0054] In another embodiment, as Figures 1 - 11 shown, the mobile welding mechanism 11 includes a reduction motor 1101 and a concave mounting frame 1103. The output end of the reduction motor 1101 is drivingly connected with a moving roller 1102 through a reducer. The moving roller 1102 is installed through the bearing inside the concave mounting frame 1103. The reduction motor 1101 is fixedly installed on the outside of the concave mounting frame 1103 through a bracket. One end of the moving roller 1102 away from the reduction motor 1101 is fixedly connected with a reduction mounting disc 1107. A reduction disc frame 1106 is sleeved on the outside of the reduction mounting disc 1107. A number of reduction magnets 1111 are installed in a groove-embedded manner on the relative sides of the reduction disc frame 1106 and the reduction mounting disc 1107. A number of rubber cushion strips 1110 are fixedly installed on the outside of the moving roller 1102. Two limiting rollers 1108 are movably installed through the shaft seats inside the concave mounting frame 1103. Limiting chucks 1109 are fixedly sleeved on the outside of both ends of the two limiting rollers 1108. The concave mounting frame 1103 is movably sleeved on the outside of the moving rail mechanism 5. The outside of the moving roller 1102 and the limiting rollers 1108 are in rolling contact with the outside of the convex sliding plate 501 and the concave outer plate 502. The limiting chucks 1109 are movably inserted into the gaps at the top ends of the convex sliding plate 501 and the concave outer plate 502. An electric telescopic rod two 1104 is fixedly installed at the bottom of the concave mounting frame 1103. A welding head 1105 is fixedly installed at the bottom end of the electric telescopic rod two 1104.

[0055] When welding is required, the reduction motor 1101 rotates at this time, driving the moving roller 1102 to rotate. The moving roller 1102 contacts the rubber cushion strip 1110 with the short rubber cushion 504 and the long rubber cushion 505, and thus rolls on the top of the convex slide plate 501 and the concave outer plate 502, thereby adjusting the moving position. The concave mounting frame 1103 rolls on the top of the convex slide plate 501 and the concave outer plate 502 with the limiting roller 1108, and assists in maintaining the position with the moving roller 1102, forming the effect of triangular rolling support, which is convenient for maintaining the relative stability of the concave mounting frame 1103. And when moving, the limiting chuck 1109 rolls at the convex gap of the convex slide plate 501 and the concave outer plate 502. One side of the limiting chuck 1109 contacts the concave inner side of the concave outer plate 502, and the other side of the limiting chuck 1109 contacts both sides of the convex top of the convex slide plate 501, thereby performing lateral limiting on the moving positions of the moving roller 1102 and the concave mounting frame 1103, thus maintaining relative stability and facilitating the relative stability of the structural operation. After the lateral movement, the extension of the second electric telescopic rod 1104 prompts the welding head 1105 to perform auxiliary operations on the structure, which is convenient for movement and welding.

[0056] In another embodiment, as Figure 11 、 Figure 13 and Figure 14 shown, the deceleration magnets 1111 are evenly distributed in a circle on the opposite sides of the deceleration mounting plate 1107 and the deceleration plate frame 1106.

[0057] When the moving roller 1102 rotates accordingly, it promotes the relative rotation of the deceleration mounting plate 1107 and the deceleration plate frame 1106, and generates a magnetic adsorption resistance at the opposite ends of the limiting roller 1108. And the metal materials of the deceleration plate frame 1106 and the deceleration mounting plate 1107 will generate electromagnetic resistance. According to Lenz's law, when a rotating conductive material makes a cutting magnetic induction line movement in the magnetic field of the circumferentially distributed magnets, an induced electromotive force and an induced current will be generated, and then an Ampere force opposite to the rotation direction of the rotating shaft will be generated, forming electromagnetic damping. This electromagnetic damping will additionally increase a torque that hinders the rotation of the rotating shaft, and jointly act with the deceleration torque generated by the interaction between the original magnets, so that the total deceleration effect is enhanced, thereby cooperating to keep the rotation position of the moving roller 1102 stable, playing a role in maintaining relative stability, avoiding shaking, and increasing the relative stability of the structure.
