Description

Technical Field

[0001] This invention relates to the field of automotive acoustic warning devices, specifically to an electric car horn. Background Technology

[0002] The car horn is a core acoustic warning component of a vehicle. It generates sound through vibrations produced by an electromagnetic structure inside the horn body, which is then amplified through the horn opening to transmit a warning signal, making it crucial for driving safety. Because the horn opening is constantly exposed to the open environment of the engine compartment or the front of the vehicle, it is susceptible to dust accumulation, rainwater intrusion, and impacts from road stones, requiring regular disassembly and installation for cleaning, inspection, or replacement.

[0003] However, the existing connection structure between the horn mouth and the horn body of car electric horns has obvious defects: First, most use bolt fixing, requiring tools such as wrenches and screwdrivers for disassembly and assembly. However, the installation space for electric horns in the engine compartment is small, making it difficult to reach the tools, resulting in extremely low maintenance efficiency. Second, bolts are prone to corrosion when exposed to high temperature, oil, and moisture for a long time, which not only increases disassembly resistance but may also cause stripping, jamming, or even require damage to the parts to disassemble. Third, although a few snap-fit ​​connections do not require tools, the low precision of the snap-fit ​​and slot fit makes it easy for positioning deviations to occur during disassembly and assembly. After installation, the large sealing gap allows external moisture and dust to easily seep into the horn body, leading to electromagnetic component failure and sound distortion. Fourth, the continuous vibration of the vehicle during driving can easily cause the bolts to loosen or the snap-fit ​​to come off, causing the horn mouth to shift, make abnormal noises, and in severe cases, even fall off, losing the warning function and posing a safety hazard. Therefore, it is necessary to make improvements. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art.

[0005] This application provides an automotive electric horn, including a horn body, a horn mouth, and a disassembly assembly. The disassembly assembly includes a connecting cylinder, a floating cylinder, a pair of floating half-shells, an opening and closing control assembly, a locking assembly, a pair of slots, and a pair of inserts. The connecting cylinder is used to fix the floating cylinder to the horn body. The pair of floating half-shells are floatingly mounted in the inner cavity of the floating half-shells by a pair of elastic elements. The pair of slots are symmetrically arranged on the peripheral wall of the horn mouth. The pair of inserts are respectively fixed on the inner wall of each floating half-shell. The opening and closing control assembly is used to control the opening and closing of the pair of floating half-shells, and the locking assembly is used to fix the opening and closing control assembly.

[0006] The elastic element includes a slide groove, a slide rod, a pair of floating sliders, and a return spring. The slide groove is opened on the inner wall of the floating cylinder and extends along the floating direction of the floating half shell. The slide rod is fixed in the slide groove. The return spring and the pair of floating sliders are slidably sleeved on the slide rod. The pair of floating sliders are respectively fixed to the outer wall of each floating half shell. The return spring is disposed between the pair of floating sliders.

[0007] The opening and closing control assembly includes a rotating ring, which is rotatably sleeved on the outside of a pair of floating half-shells. The inner cross-section of the rotating ring and the floating cylinder is elliptical. When the pair of floating half-shells are closed, the cross-section is circular, and when they are separated, the cross-section is elliptical.

[0008] The opening and closing control assembly also includes a pair of retaining edges, which are fixed to the outer ends of the outer walls of each floating half-shell. The outer end face and inner end face of the rotating ring slide and rub against the pair of retaining edges and the end face of the connecting cylinder, respectively.

[0009] The opening and closing control assembly also includes a pair of arc grooves, a pair of limit sliders, and a pair of thrust components. The pair of arc grooves are symmetrically arranged at the front end of the floating cylinder and concentric with the rotating ring. The pair of limit sliders are slidably installed in each arc groove and fixed to the rotating ring. The pair of thrust components are arranged at one end of each arc groove and are used to apply thrust to the pair of limit sliders when the pair of floating half shells close, thereby improving the locking tightness between the locking assembly and the rotating ring.

[0010] The thrust reverser assembly includes a thrust reverser groove and a torsion spring. The thrust reverser groove is located at the end of the arc groove, and the torsion spring is fixedly installed in the thrust reverser groove. One end of the torsion spring abuts against the end face of the arc groove, and the other end abuts against the other end of the thrust reverser groove and extends into the arc groove.

[0011] The locking assembly includes a convex ring, a pair of notches, a pair of slots, and a pair of rotating connectors. The convex ring is fixed to the outer end of the outer peripheral wall of the floating cylinder. The pair of notches are respectively opened at the upper and lower ends of the convex ring with opposite opening directions. The pair of slots are symmetrically opened on the outer peripheral wall of the rotating ring. One end of the rotating connector is rotatably installed on the outer wall of the floating cylinder, and the other end can be inserted into the slot and then extend out of the slot.

[0012] The rotating connector includes a hollow rotating shell, a plug shell, and a pre-tightening spring. The rear end of the hollow rotating shell is hinged to the outer peripheral wall of the floating shell, and the front bottom is provided with a notch. The plug shell is floatingly installed in the hollow rotating shell by the pre-tightening spring. The front bottom is provided with a locking block that is slidably set in the notch for insertion into the locking slot.

[0013] The rotary connector also includes a limiting groove and a limiting block. The limiting groove is opened on the back of the convex ring, and the limiting block is fixed on the top of the insert housing and is used to engage with the limiting groove when the card block is inserted into the card slot.

[0014] The rotating connector also includes a pair of side slots and a pair of side sliders. The pair of side slots are symmetrically opened on the left and right side walls of the hollow rotating shell, and the pair of side sliders are symmetrically fixed on the left and right side walls of the shell, and slide in cooperation with the corresponding side slots.

[0015] The beneficial effects of this invention are as follows:

[0016] Tool-free quick disassembly and assembly significantly improves maintenance efficiency: This application utilizes the elliptical rotating ring of the opening and closing control component in conjunction with an elastic element. Simply rotating the ring drives the opening and closing of a pair of floating half-shells (the long shaft of the ring drives the closing, and the short shaft, in conjunction with the return spring, drives the separation). Combined with the rotating plug of the locking component (locking / unlocking can be completed by manually pushing the plug), the entire disassembly and assembly process requires no tools, completely solving the problems of inconvenient tool operation and laborious disassembly and assembly of existing bolt fixing methods and snap-fit ​​connections. It is especially suitable for the narrow space of the engine compartment, reducing the disassembly and assembly time of the horn opening by more than 60%.

[0017] Precise assembly and disassembly positioning, and high sealing reliability: The sliding groove and sliding rod of the elastic component provide precise guidance for the floating half-shell, ensuring that the alignment error between the plug and the slot is ≤0.1mm; the torsion spring of the reverse thrust component applies a continuous thrust to the limit slider when the floating half-shell closes, and with the preload of the return spring, the plug is tightly embedded in the slot, with a sealing gap of ≤0.05mm, effectively preventing rainwater and dust from seeping into the speaker body, avoiding corrosion of electromagnetic components and sound distortion, and extending the service life of the electric speaker by more than 30%.

[0018] Excellent vibration resistance and strong operational stability: The locking assembly adopts a dual locking structure of "block-slot" (limiting the circumferential rotation of the rotating ring) and "limit block-slot" (limiting the axial retraction of the insert shell). Combined with the continuous pre-tensioning of the rotating ring by the torsion spring of the reverse thrust assembly, it can withstand the continuous vibration of the vehicle from 10-50Hz (complies with GB / T18411-2019 automotive parts vibration test standard), avoiding horn mouth displacement, abnormal noise or detachment, and ensuring the stability of the driving warning function.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The following description, in conjunction with the accompanying drawings, details the car electric horn provided in this application through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides an electric car horn, including a horn body 1, a horn mouth 2, and a disassembly assembly 3. The disassembly assembly 3 includes a connecting cylinder 31, a floating cylinder 32, a pair of floating half-shells 33, an opening and closing control assembly 4, a locking assembly 5, a pair of slots 34, and a pair of inserts 35. The connecting cylinder 31 is used to fix the floating cylinder 32 to the horn body 1. The pair of floating half-shells 33 are floatingly mounted in the inner cavity of the floating half-shells 33 by a pair of elastic members 6. The pair of slots 34 are symmetrically arranged on the peripheral wall of the horn mouth 2. The pair of inserts 35 are respectively fixed on the inner wall of each floating half-shell 33. The opening and closing control assembly 4 is used to control the opening and closing of the pair of floating half-shells 33. The locking assembly 5 is used to fix the opening and closing control assembly 4.

[0033] In this embodiment of the application, the elastic element 6 includes a groove 61, a slide rod 62, a pair of floating sliders 63, and a return spring 64. The groove 61 is formed on the inner wall of the floating cylinder 32 and extends along the floating direction of the floating half shell 33. The slide rod 62 is fixed in the groove 61. The return spring 64 and the pair of floating sliders 63 are slidably sleeved on the slide rod 62. The pair of floating sliders 63 are respectively fixed to the outer wall of each floating half shell 33. The return spring 64 is disposed between the pair of floating sliders 63.

[0034] like Figures 1 to 7 As shown, due to the above structure, a pair of elastic elements 6 are symmetrically arranged on the upper and lower sides of the inner wall of the floating cylinder 32. The slide rod 62 is fixed in the positioning holes at both ends of the slide groove 61 by interference fit. Its diameter is 0.05-0.1mm smaller than the hole diameter of the floating slider 63, ensuring that the floating slider 63 can slide flexibly without obvious shaking. When the opening and closing control component 4 drives the pair of floating half shells 33 to close, the floating half shells 33 drive the floating sliders 63 on the outer wall to move towards each other. The return spring 64 located between the two sliders is compressed and shortened (storage). The elastic element 6 stores elastic potential energy, allowing the insert 35 to be tightly embedded in the slot 34 of the horn mouth 2. When the opening and closing control component 4 releases the restriction on the floating half shell 33, the return spring 64 releases elastic potential energy, pushing a pair of floating sliders 63 to separate on both sides, thereby driving a pair of floating half shells 33 to move outward synchronously to achieve separation. At this time, the insert 35 disengages from the slot 34, completing the disassembly action of the horn mouth 2. The elastic element 6 precisely controls the opening and closing state of the floating half shell 33 through the cycle of "compression energy storage - release work", ensuring the stability of the disassembly and assembly process.

[0035] Example 2:

[0036] The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the opening and closing control component 4 includes a rotating ring 41, which is rotatably sleeved on the outside of a pair of floating half-shells 33. The inner cavity cross-section of the rotating ring 41 and the floating cylinder 32 is elliptical. When the pair of floating half-shells 33 are closed, the cross-section is circular, and when they are separated, the cross-section is elliptical.

[0037] In this embodiment of the application, the opening and closing control component 4 further includes a pair of retaining edges 42, which are respectively fixed to the outer ends of the outer walls of each floating half shell 33. The outer end face and inner end face of the rotating ring 41 slide and rub against the pair of retaining edges 42 and the end face of the connecting cylinder 31, respectively.

[0038] like Figures 1 to 7 As shown, due to the above structure, the radial clearance between the rotating ring 41 and the floating half-shell 33 is 0.1-0.2mm, ensuring that the rotating ring 41 can rotate flexibly without excessive wobbling. The retaining edge 42 is an annular protrusion structure with an axial width of 3-5mm. The outer and inner end faces of the rotating ring 41 slide and rub against the end faces of the pair of retaining edges 42 and the connecting cylinder 31, respectively. The surface roughness of the contact surface is no greater than Ra1.6μm to reduce frictional resistance. When the rotating ring 41 rotates until its short axis aligns with the mating surfaces of the pair of floating half-shells 33, the elastic potential energy of the return spring 64 in the compressed state is released. The rotating ring 41 pushes the adjacent pair of floating sliders 63 to separate up and down, causing the floating half-shell 33 to separate up and down synchronously (the cross-section is elliptical). When the rotating ring 41 rotates until its long axis is aligned with the contact surface of the floating half-shell 33, the radial thrust of the rotating ring 41 overcomes the elastic force of the return spring 64, forcing the floating sliders 63 to move towards each other and compress the return spring 64, so that the floating half-shell 33 closes (the cross-section is circular). During this process, the elastic element 6 and the opening and closing control component 4 form a counterforce cooperation, and the mechanical thrust of the rotating ring 41 and the elastic force of the return spring 64 form a dynamic balance, realizing the stable switching of the opening and closing state of the floating half-shell 33.

[0039] Example 3:

[0040] The difference from Embodiment 2 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the opening and closing control component 4 also includes a pair of arc grooves 43, a pair of limiting sliders 44, and a pair of reverse thrust components. The pair of arc grooves 43 are symmetrically arranged at the front end of the floating cylinder 32 and concentric with the rotating ring 41. The pair of limiting sliders 44 are slidably installed in each arc groove 43 and fixedly connected to the rotating ring 41. The pair of reverse thrust components are respectively arranged at one end of each arc groove 43 and are used to apply a thrust to the pair of limiting sliders 44 when the pair of floating half shells 33 are closed, thereby improving the locking tightness between the locking component 5 and the rotating ring 41.

[0041] In this embodiment of the application, the thrust reverser assembly includes a thrust reverser groove 45 and a torsion spring 46. The thrust reverser groove 45 is disposed at the end of the arc groove 43, and the torsion spring 46 is fixedly installed in the thrust reverser groove 45. One end of the torsion spring 46 abuts against the end face of the arc groove 43, and the other end abuts against the other end of the thrust reverser groove 45 and extends into the arc groove 43.

[0042] like Figures 1 to 7As shown, due to the above structure, the central angle of the arc groove 43 is 90°, which corresponds exactly to the rotation angle of the rotating ring 41 from closing to separating from the floating half-shell 33. The torsion spring 46 is respectively engaged with the positioning post on the inner wall of the thrust groove 45 and the protrusion on the end face of the arc groove 43 through the end hook. In the natural state, one end of the torsion spring 46 extends into the arc groove 43 by 5-8mm. When the rotating ring 41 rotates, the fixed limiting slider 44 slides along the arc groove 43 at the front end of the floating cylinder 32. When the rotating ring 41 drives the floating half-shell 33 to close (the cross-section is circular), the limiting slider 44 slides to the end of the arc groove 43 and squeezes the torsion spring 46 of the thrust assembly. The torsion spring 46 deforms due to the deformation. A reverse thrust is generated and acts on the limiting slider 44, keeping the rotating ring 41 tightly engaged with the locking assembly 5, preventing the rotating ring 41 from loosening due to vibration or other factors, thereby improving the tightness of the subsequent locking of the locking assembly 5 and the rotating ring 41. When it is necessary to open the floating half shell 33, the locking assembly 5 is operated to release the locking state of the rotating ring 41, and the rotating ring 41 is rotated in the opposite direction. The torsion spring 46 assists the limiting slider 44 to slide along the arc groove 43 to the other end, causing the long axis of the rotating ring 41 to be perpendicular to the contact surface of the pair of floating half shells 33, so that the pair of floating half shells 33 separate. The guiding effect of the arc groove 43 on the limiting slider 44 ensures the precise control of the rotation angle of the rotating ring 41.

[0043] Example 4:

[0044] The difference from Embodiment 3 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the locking assembly 5 includes a convex ring 51, a pair of notches 52, a pair of slots 53, and a pair of rotating connectors 54. The convex ring 51 is fixed to the outer end of the outer peripheral wall of the floating cylinder 32. The pair of notches 52 are respectively opened at the upper and lower ends of the convex ring 51, with opposite opening directions. The pair of slots 53 are symmetrically opened on the outer peripheral wall of the rotating ring 41. One end of the rotating connector 54 is rotatably mounted on the outer wall of the floating cylinder 32, and the other end can be inserted into the slot 53 and then extend out of the slot 53.

[0045] In this embodiment of the application, the rotating connector 54 includes a hollow rotating shell 541, a plug shell 542, and a pre-tensioning spring 543. The rear end of the hollow rotating shell 541 is hinged to the outer peripheral wall of the floating shell, and the bottom of the front end is provided with a notch. The plug shell 542 is floatingly installed in the hollow rotating shell 541 by means of the pre-tensioning spring 543. The bottom of the front end is provided with a card block 544 that is slidably disposed in the notch for insertion into the card slot 53.

[0046] like Figures 1 to 7As shown, due to the aforementioned structure, the rear end of the hollow rotating shell 541 is hinged to the outer peripheral wall of the floating cylinder 32 via a pin with a diameter of 4-6 mm. Lubricant is provided at the hinge to ensure rotational flexibility. One end of the preload spring 543 abuts against the end of the hollow rotating shell 541, and the other end is inserted into the inner cavity of the insert shell 542. In its natural state, it is in a slightly compressed state. After the rotating ring 41 is adjusted to the closed state of the floating half-shell 33, the hollow rotating shell 541 of the rotating insert 54 is rotated so that its front end aligns with the groove 53 on the outer peripheral wall of the rotating ring 41. The preload spring 543 pushes the insert shell 542 to move along the hollow rotating shell 541, causing the insert shell... The locking block 544 at the bottom of 542 passes through the notch of the hollow rotating shell 541 and is inserted into the slot 53. The length of the locking block 544 extending out of the slot 53 is 2-3mm, and it cooperates with the notch 52 of the convex ring 51 (because the opening direction of the notch 52 is opposite, it can limit the upper and lower rotating inserts 54 respectively), thereby achieving mechanical locking of the rotating ring 41 and preventing the rotating ring 41 from rotating accidentally. When unlocking is required, the insert shell 542 is pulled outward to compress the pre-tension spring 543, so that the locking block 544 is disengaged from the slot 53 and the notch 52. Then, the hollow rotating shell 541 is rotated to release the lock. The entire locking process does not require tools, is convenient to operate, and locks firmly.

[0047] Example 5:

[0048] The difference from Embodiment 4 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the rotating connector 54 also includes a limiting groove 545 and a limiting block 546. The limiting groove 545 is formed on the back of the convex ring 51, and the limiting block 546 is fixed on the top of the insert shell 542 for engaging with the limiting groove 545 when the locking block 544 is inserted into the locking groove 53.

[0049] like Figures 6 to 7 As shown, due to the aforementioned structure, the limiting block 546 is a hemispherical protrusion with a diameter of 3-5mm, and the limiting groove 545 is a matching arc-shaped groove with a depth of 1.5-2.5mm. When the locking block 544 of the insert shell 542 is inserted into the slot 53, the limiting block 546 at the top of the insert shell 542 simultaneously engages with the limiting groove 545 on the back of the convex ring 51, forming a double locking structure: the locking block 544 cooperates with the slot 53 to restrict the circumferential rotation of the rotating ring 41, and the limiting block 546 cooperates with the limiting groove 545 to restrict the axial movement of the insert shell 542, preventing the insert shell 542 from retracting due to vehicle vibration and causing the locking block 544 to disengage from the slot 53, further improving the anti-loosening performance of the locking assembly 5. When unlocking, pulling the insert shell 542 causes the limiting block 546 to disengage from the limiting groove 545 while the locking block 544 disengages from the slot 53, ensuring the synchronicity and reliability of the operation.

[0050] Example 6:

[0051] The difference from Embodiment 5 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the rotating connector 54 also includes a pair of side grooves 547 and a pair of side sliders 548. The pair of side grooves 547 are symmetrically opened on the left and right side walls of the hollow rotating shell 541, and the pair of side sliders 548 are symmetrically fixed on the left and right side walls of the insert shell 542, and slide in cooperation with the corresponding side grooves 547.

[0052] like Figure 7 As shown, due to the aforementioned structure, the length of the side groove 547 is 15-20mm, and its width is 0.1-0.2mm larger than that of the side slider 548. The thickness of the side slider 548 is 2-3mm. When the insert shell 542 moves within the hollow rotating shell 541 under the action of the pre-tension spring 543, the side sliders 548 on both sides of the insert shell 542 slide along the side groove 547 of the hollow rotating shell 541. The cooperation between the side groove 547 and the side slider 548 not only guides the movement direction of the insert shell 542, preventing the insert shell 542 from shifting or rotating during movement, but also ensures that the locking block 544 can be accurately aligned and inserted. The insert block 544 is inserted into the slot 53; at the same time, the side groove 547 forms an axial limit on the side slider 548. The length of the side groove 547 is not less than the maximum moving distance of the insert shell 542, ensuring that the side slider 548 is still located in the side groove 547 when the insert block 544 is fully inserted into the slot 53. This can effectively prevent the insert shell 542 from detaching from the hollow rotating shell 541 in the vertical direction, avoiding the insert shell 542 from falling off due to vibration or improper operation. This structural design can also reduce the wear caused by shaking between the insert shell 542 and the hollow rotating shell 541, extend the service life of the components, and further improve the stability and accuracy of the rotating insert 54's movement.
