Description

Technical Field

[0001] The present invention belongs to the technical field of speaker assembly, and particularly relates to a fixture for fixing a speaker housing that is convenient for flipping. Background Art

[0002] A speaker housing is a square housing used to install a speaker. The design of the housing can range from a simple homemade DIY rectangular particleboard box to a very complex and expensive computer-designed high-fidelity speaker box, and these cabinets use composite materials, internal baffles, speakers, bass reflex ports, and sound insulation. The main function of the housing is to prevent the sound waves generated by the rear surface of the diaphragm of an open speaker driver from interacting with the sound waves generated in front of the speaker driver. The housing can also manage the vibrations caused by the movement of air within the driver frame and the housing, as well as the heat generated by the driver voice coil and amplifier (especially woofers and subwoofers).

[0003] When assembling an existing speaker housing and a speaker, it is necessary to first fix the speaker housing on a designated fixing rack to facilitate the assembly of the speaker housing and the speaker. However, since the speaker housing needs to be flipped during the assembly process, when the top of the speaker housing and the speaker are assembled, it is necessary to remove the speaker housing and the speaker from the fixing device and flip them. And after flipping, it is necessary to place the speaker housing back on the fixing rack to complete the assembly operation of the bottom of the speaker housing and the speaker, resulting in a low assembly efficiency of the speaker housing and the speaker.

[0004] Therefore, it is very necessary to invent a fixture for fixing a speaker housing that is convenient for flipping to solve the above problems. Summary of the Invention

Gears are sleeved on the parts of the rotating shaft on the front and rear sides of the receiving plate. Two groups of teeth are symmetrically arranged on the groove wall of the storage groove away from the strip-shaped hole, and the two groups of teeth are respectively engaged with the two gears. Two sliders are rotatably sleeved on the rotating shaft. Vertical sliding holes are formed through the vertical plates at the corresponding positions of the sliders, and the two sliders are respectively slidably inserted through and inserted into the two sliding holes. The ends of the two sliders away from the rotating shaft are fixedly connected to the same connecting plate. A positioning groove is formed in the horizontal direction on the side of the connecting plate away from the vertical plate.

[0008] Further, the power assembly includes two mounting plates respectively located on both sides of the fixed plate, and the mounting plates are fixedly connected to the top of the base. Motors are mounted on the opposite sides of the two fixed plates. The output shafts of the motors are sequentially vertically rotatably inserted through the mounting plates and the strip-shaped holes on the corresponding sides of the fixed plates. The parts of the output shafts of the motors located in the strip-shaped holes are vertically fixedly connected with two strip plates, and the included angle between the two strip plates is an obtuse angle. A dial rod is vertically fixedly connected to the side of the strip plate close to the connecting plate, and the two dial rods are respectively inserted into the positioning grooves of the upper and lower connecting plates. Two positioning pins are slidably inserted into the opposite sides of the fixed plate and the mounting plate, and the two positioning pins are symmetrical about the output shaft of the motor. A first spring is fixedly connected between the end of the positioning pin located inside the fixed plate and the fixed plate. A ball is mounted at the other end of the positioning pin. A spherical positioning hole matching the ball is formed on the mounting plate at the corresponding position of the ball, and the connection line of the two spherical positioning holes is parallel to the base.

[0009] Further, the clamping device includes a clamping plate. A storage groove is formed on the front or rear hole wall of the corresponding fixed hole of the clamping plate, and the clamping plate is located in the corresponding storage groove. Electric telescopic rods are vertically connected to the opposite sides of the two clamping plates. The electric telescopic rods are inserted through the front or rear positions of the fixed plate.

[0011] Further, the support plate is located at the exact bottom position of the fixing hole, and the support plate is in a horizontal state in its natural state.

[0012] Further, the maximum deflection angle of the receiving plate is ninety degrees, and a rubber strip is connected to the side of the receiving plate away from the rotating shaft.

[0013] Further, a bearing is fixedly sleeved on the lever, and the diameter of the bearing matches the size of the positioning groove.

[0014] Further, the frictional force between the ball and the spherical positioning hole is greater than the maximum frictional force generated when the lever pushes the connecting plate along the sliding groove.

[0015] The technical effects and advantages of the present invention:

[0016] 1. During assembly, when it is necessary to flip the speaker housing, start the power assembly, which drives the fixed plate, the speaker housing, and the speaker to rotate 180 degrees together. After the fixed plate rotates 180 degrees, the two receiving devices can still support the flipped speaker housing. After the assembly is completed, reset the clamping device, and at the same time start the power assembly, which drives the two receiving devices to return to a certain angle. Subsequently, the assembled speaker housing and speaker can automatically slide along the top of the unloading device to the base, thereby improving the assembly efficiency of the speaker housing and the speaker.

[0017] 2. When the assembled speaker housing and speaker fall onto the support plate, the support plate starts to slowly deflect downward due to the pressure of the speaker housing and the speaker. During this process, the telescopic column and the second spring start to contract under the pressure of the support plate on the support roller, thereby playing a buffering and protective role for the speaker housing and the speaker. When the telescopic column reaches the maximum contraction amount, the tops of the support plate and the movable plate are in the same plane. At this time, the assembled speaker housing and speaker can slowly slide along this plane to the base, thereby realizing the automatic unloading operation of the assembled speaker housing and speaker while protecting the integrity of the finished speaker.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] The present invention provides Figures 1-6 The illustrated fixture for fixing a speaker housing that is easy to flip comprises a base 1, a fixing plate 2 being provided on the top of the base 1, a square fixing hole being penetrated through the top of the fixing plate 2, receiving devices 3 for supporting the speaker housing being provided on both sides of the top of the fixing hole, strip holes being penetrated through the fixing plate 2 at corresponding positions on one side of the two receiving devices 3, and a power assembly 4 being provided in the strip holes, clamping devices 5 for clamping the speaker housing being provided on the front and rear sides of the fixing plate 2, and a discharge device 6 for transferring the speaker housing being provided at the bottom of the fixing plate 2;

[0029] When assembling the speaker housing and the speaker, first place the speaker housing on the receiving device 3 through the fixing hole on the fixing plate 2. At this time, the speaker housing can be supported by the two receiving devices 3. Then start the clamping device 5 so that the speaker housing can be clamped by the two clamping devices 5. Then put the speaker into the speaker housing and install it. When the speaker housing needs to be flipped over and installed, start the power component 4 to drive the fixing plate 2, the speaker housing and the speaker to rotate one hundred and eighty degrees together. After the fixing plate 2 rotates one hundred and eighty degrees, the two receiving devices 3 can also support the flipped speaker housing. When the assembly is completed, reset the clamping device 5 and start the power component 4 at the same time, thereby driving the two receiving devices 3 to restore a certain angle. Subsequently, the assembled speaker housing and speaker can fall on the top of the unloading device 6 and automatically slide to the base 1 along the top of the unloading device 6 under the action of gravity, thereby improving the assembly efficiency of the speaker housing and the speaker.

[0030] like Figure 4 and Figure 5As shown, the receiving device 3 includes two vertical plates 31. The two vertical plates 31 are symmetrically and fixedly connected to the top and bottom positions of the fixed plate 2. A deflection groove is formed on the side of the vertical plate 31 away from the strip hole. A receiving plate 32 is arranged in the deflection groove. A rotating shaft 33 is fixedly connected to the bottom of the receiving plate 32. Vertical limiting holes are formed through the front and rear side walls of the deflection groove at the corresponding positions of the front and rear ends of the rotating shaft 33. The front and rear ends of the rotating shaft 33 respectively penetrate and are inserted into the corresponding limiting holes. Gears 34 are sleeved on the parts of the rotating shaft 33 on the front and rear sides of the receiving plate 32. Two groups of teeth are symmetrically arranged on the groove wall of the receiving groove away from the strip hole. The two groups of teeth are respectively engaged with the two gears 34. Two sliders 35 are rotatably sleeved on the rotating shaft 33. Vertical sliding holes are formed through the vertical plates 31 at the corresponding positions of the sliders 35. The two sliders 35 respectively slide through and are inserted into the two sliding holes. The ends of the two sliders 35 away from the rotating shaft 33 are fixedly connected to the same connecting plate 36. A positioning groove is formed in the horizontal direction on the side of the connecting plate 36 away from the vertical plate 31. The maximum deflection angle of the receiving plate 32 is ninety degrees. A rubber strip 7 is connected to the side of the receiving plate 32 away from the rotating shaft 33;

[0031] The power assembly 4 includes two mounting plates 41. The two mounting plates 41 are respectively located on both sides of the fixed plate 2. The mounting plates 41 are fixedly connected to the top of the base 1. Motors 42 are respectively installed on the sides of the two fixed plates 2 away from each other. The output shafts of the motors 42 sequentially penetrate and rotate vertically through the mounting plates 41 and the strip holes on the corresponding sides of the fixed plate 2. Two strip plates 43 are vertically fixedly connected to the parts of the output shafts of the motors 42 in the strip holes. The included angle between the two strip plates 43 is an obtuse angle. A dial rod 44 is vertically fixedly connected to the side of the strip plate 43 close to the connecting plate 36. The two dial rods 44 are respectively inserted into the positioning grooves of the upper and lower connecting plates 36. Two positioning pins 45 are slidably inserted into the sides of the fixed plate 2 opposite to the mounting plates 41. The two positioning pins 45 are symmetrical about the output shaft of the motor 42. A first spring 46 is fixedly connected between the end of the positioning pin 45 inside the fixed plate 2 and the fixed plate 2. A ball 47 is installed at the other end of the positioning pin 45. Spherical positioning holes 48 matching the ball 47 are formed on the mounting plates 41 at the corresponding positions of the ball 47. The connection line of the two spherical positioning holes 48 is parallel to the base 1. A bearing 8 is fixedly sleeved on the dial rod 44. The diameter of the bearing 8 matches the size of the positioning groove. The friction force between the ball 47 and the spherical positioning hole 48 is greater than the maximum friction force generated when the dial rod 44 pushes the connecting plate 36 along the sliding groove;

[0032] In the initial state, the two receiving plates 32 located at the bottom of the fixing plate 2 can maintain a horizontal state, and the two receiving plates 32 located at the top of the fixing plate 2 can be received in the corresponding deflection grooves. At the same time, the fixing plate 2 can maintain a horizontal state under the cooperation of the ball 47 and the spherical positioning hole 48;

[0033] During assembly, first place the speaker housing into the fixing hole, and make the bottom of the speaker housing be supported by the two receiving plates 32 located at the bottom of the fixing plate 2. Then start the two clamping devices 5 simultaneously, so that the two clamping devices 5 can clamp the speaker housing from the front and back of the speaker housing at the same time. Subsequently, the speaker can be placed into the speaker housing and assembled;

[0034] When the assembly of the top of the speaker housing and the speaker is completed, start the two motors 42 simultaneously, so that the two strip plates 43 on the output shafts of the motors 42 can start to rotate around the output shafts of the motors 42 under the action of the motors 42. As the two strip plates 43 rotate simultaneously, the two strip plates 43 drive the two lever rods 44 to slide along the positioning grooves on the corresponding connecting plates 36, so that the two connecting plates 36 can drive the two rotating shafts 33 to move upward simultaneously under the cooperation of the corresponding lever rods 44, positioning grooves and sliders 35. As the two rotating shafts 33 move upward, the two rotating shafts 33 located at the bottom can drive the two receiving plates 32 to deflect downward simultaneously and gradually be received into the deflection grooves of the corresponding vertical plates 31 under the cooperation of the gears 34 and the teeth. The rotating shaft 33 located at the top can also drive the corresponding receiving plate 32 to deflect downward and gradually rotate out of the deflection groove of the corresponding vertical plate 31 under the cooperation of the gears 34 and the teeth. When the two receiving plates 32 located at the bottom are completely received into the corresponding deflection grooves, the two receiving plates 32 located at the top are exactly in a horizontal state. At this time, as the motors 42 continue to rotate, the force applied by the motors 42 to the connecting plates 36 through the strip plates 43 and the lever rods 44 gradually increases, so that the ball 47 can compress the first spring 46 through the positioning pin 45 and move out of the spherical positioning hole 48 under the action of this force. And when the positioning pin 45 moves out of the spherical positioning hole 48, the fixing plate 2 and the speaker housing can rotate 180 degrees together driven by the motors 42. Then turn off the motors 42. At this time, the ball 47 on the side of the fixing plate 2 can be reinserted into the corresponding spherical positioning hole 48 after rotation under the action of the first spring 46, so as to realize the re-locking of the fixing plate 2;

[0035] After the fixing plate 2 finishes flipping, the speaker housing also completes the flipping operation along with the fixing plate 2. Compared with the existing fixing bracket, the flipping efficiency of the speaker housing and the speaker is improved, thereby also improving the assembly efficiency of the speaker housing and the speaker. Subsequently, the two clamping devices 5 are slowly reset by a certain distance, so that the speaker housing can fall onto the two receiving plates 32 located at the bottom at this time under the action of gravity, thereby facilitating the assembly of the bottom of the flipped speaker housing and the speaker;

[0036] After the speaker housing and the speaker are assembled, the motor 42 is started again, so that the two receiving plates 32 located at the bottom can deflect downward under the action of the motor 42, and the speaker housing and the speaker can gradually move downward along with the downward deflection of the two receiving plates 32. During this process, when the distance between the two receiving plates 32 is equal to the width of the speaker housing, as the two receiving plates 32 continue to deflect, the rubber strips 7 on the two receiving plates 32 can deform due to the extrusion of the speaker housing and the speaker, thereby softly clamping the two sides of the speaker housing. And as the two clamping devices continue to deflect, the speaker housing and the speaker can finally slowly fall onto the unloading device 6 under the combined action of the two receiving plates 32 and the rubber strips 7, thereby avoiding the speaker housing and the speaker from quickly falling onto the unloading device 6 due to the loss of the support of the receiving plates 32, and further protecting the speaker housing and the speaker from being damaged;

[0037] Subsequently, the speaker housing and the speaker can slowly slide along the top of the unloading device 6 to the base 1, thereby improving the assembly efficiency of the speaker housing and the speaker.

[0038] As Figure 1 and Figure 2 shown, the clamping device 5 includes a clamping plate 51. A receiving groove is formed in the front or rear hole wall of the fixing hole at the corresponding position of the clamping plate 51, and the clamping plate 51 is located in the corresponding receiving groove. Electric telescopic rods 52 are vertically connected to the separated sides of the two clamping plates 51. The electric telescopic rods 52 are inserted through the front or rear position of the fixing plate 2. Limiting rods 53 are arranged on both sides of the electric telescopic rods 52. The limiting rods 53 are vertically slidably inserted through the receiving grooves on the front or rear side of the fixing plate 2, and the limiting rods 53 are fixedly connected to the clamping plates 51;

[0039] When the speaker housing is placed in the fixing hole, the bottom of the speaker housing can be supported by the two receiving plates 32, and then the two electric telescopic rods 52 are started at the same time, so that the two clamping plates 51 can clamp the front and back sides of the speaker housing at the same time under the cooperation of the two electric telescopic rods 52 and the limit rods 53, thereby facilitating the assembly of the speaker housing and the speaker, and in the process of the fixing plate 2 driving the speaker housing to flip, the clamping device 5 can prevent the speaker housing from slipping out of the fixing hole during the flipping process.

[0040] like Figure 1 and Figure 6 As shown, the unloading device 6 includes a support plate 61, both sides of the support plate 61 are rotatably connected to support rods 62, the support rods 62 are fixedly connected to the top of the base 1, the front side of the support plate 61 is hinged with a movable plate 63, the bottom of the support plate 61 is horizontally provided with a support roller 64, both ends of the support roller 64 are rotatably connected to a telescopic column 65, the bottom of the telescopic column 65 is fixedly connected to the top of the base 1, a second spring 66 is sleeved on the telescopic column 65, and when the telescopic column 65 is fully retracted, the top of the support plate 61 and the movable plate 63 are located in the same plane, the support plate 61 is located at the bottom of the fixing hole, and the support plate 61 is in a horizontal state in the natural state;

[0041] When the assembled speaker housing and speaker fall onto the support plate 61, the support plate 61 begins to slowly deflect downward due to the pressure of the speaker housing and the speaker. During this process, as the support plate 61 deflects downward, the movable plate 63 deflects downward together with the support plate 61. At the same time, the telescopic column 65 and the second spring 66 begin to contract under the pressure of the support plate 61 on the support roller 64, thereby providing a buffering protection for the speaker housing and the speaker. When the telescopic column 65 reaches the maximum contraction amount, the top of the support plate 61 and the movable plate 63 are located in the same plane. At this time, the assembled speaker housing and the speaker can slowly slide along the plane onto the base 1, thereby realizing the automatic unloading operation of the assembled speaker housing and the speaker, and avoiding the assembled speaker housing and the speaker from falling from the top of the support plate 61 and the movable plate 63 due to excessive sliding speed, thereby improving the assembly efficiency of the speaker and the speaker housing, and protecting the integrity of the finished speaker.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
