Description
Technical Field
[0001] This invention relates to the field of vehicle technology, and more particularly to a locking device, audio equipment, and vehicle. Background Technology
[0002] To meet users' needs in various scenarios, some existing car audio systems are now detachable, allowing them to be used not only inside the vehicle but also removed from the vehicle's mounting location for use in various external settings such as homes and offices.
[0003] In existing technologies, such detachable speakers are typically mounted in a vehicle mounting box using a locking mechanism, with locking holes on the surface of the mounting box. When the locking mechanism engages with the locking holes, the speaker is securely and reliably fixed in the mounting box; when the locking mechanism disengages from the locking holes, the speaker can be removed from the mounting box. However, in existing structures, removing the speaker usually requires the user to manually pull it out of the mounting box, which is not only inconvenient but also prone to damaging the speaker or mounting structure during the removal process. Furthermore, the locking and unlocking actions of existing locking mechanisms are generally achieved using motor drives, which not only increases the overall cost of the locking mechanism but also increases the failure rate of the mechanism, while reducing the operability and reliability of the locking mechanism in emergency scenarios such as power outages.
[0004] Therefore, there is an urgent need for a locking device, audio equipment, and vehicle to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a locking device, audio equipment, and vehicle that improves the ease of operation, reduces the overall cost and failure rate, and ensures operability and reliability in emergency scenarios such as power outages.
[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, a locking device is provided, comprising: The mounting base has a mounting slot on it, and the speaker body can be installed in the mounting slot; The locking element is movably mounted on the mounting base and has a locked state that engages with the speaker body and an unlocked state that releases it from the speaker body. Both the first linkage component and the second linkage component are movably mounted on the mounting base, and the second linkage component is connected to the locking component; A trigger component and a pusher component are provided. The pusher component is movably mounted on the mounting base and can support at least part of the speaker body. The trigger component is movably connected to both the first linkage component and the pusher component. The first linkage component is activated, moving to contact with the second linkage component and causing the second linkage component to activate. The second linkage component causes the locking element to switch from the locked state to the unlocked state. At the same time, the first linkage component triggers the activation of the triggering component. Once the locking element switches to the unlocked state, the triggering component activates the pushing component, which pushes the speaker body to move a preset distance out of the mounting slot.
[0007] Optionally, the first linkage component is movably disposed on the mounting base along the first direction, and the trigger component includes a trigger member and a first elastic member. The trigger member is movably connected to the push member along the second direction, and the first elastic member is disposed on the mounting base and connected to the push member. When the locking member is in the locked state, the trigger member is engaged with the push member of the mounting base, and the first elastic member accumulates elastic potential energy. The first linkage component is driven to move, which in turn drives the trigger and the second linkage component to move. The second linkage component drives the locking component to switch from the locked state to the unlocked state. The trigger moves until it is disengaged from the push component. Once the locking component switches to the unlocked state, the push component moves under the elastic force of the first elastic component and pushes the speaker body to move. The first direction and the second direction are set at an angle.
[0008] Optionally, the pushing member includes a connecting part and a pushing plate connected together, a first elastic member is connected to the connecting part, the connecting part is provided with a locking hole, the pushing plate can fit against at least a part of the surface of the speaker body, and when the locking member is in the locked state, the trigger member is inserted into the locking hole; The first linkage component is driven to move, and the first linkage component drives the trigger to move to disengage from the locking hole. When the locking component switches to the unlocked state, the connecting part moves under the elastic force of the first elastic component and drives the push plate to push the speaker body to move.
[0009] Optionally, the pusher also includes an auxiliary plate, which is connected to the pusher plate; when the speaker body moves a preset distance from the mounting slot, a portion of the auxiliary plate protrudes relative to the mounting base.
[0010] Optionally, the trigger is provided with an inclined extending guide groove, and the first linkage component is provided with a sliding part, which slides in cooperation with the guide groove; when the first linkage component is driven to move along the first direction, the sliding part can drive the trigger to move along the second direction under the action of the groove wall of the guide groove.
[0011] Optionally, the locking element is rotatably mounted on the mounting base in a third direction, and the second linkage assembly includes a third linkage element and a fourth linkage element. Both the third linkage element and the fourth linkage element are rotatably mounted on the mounting base in a third direction. One end of the third linkage element is connected to one end of the fourth linkage element, and the other end of the fourth linkage element is connected to the locking element. The first linkage component is driven to move, and the first linkage component moves to contact the third linkage component and push the third linkage component to rotate. The third linkage component drives the fourth linkage component to rotate, and the fourth linkage component drives the locking component to rotate. The locking component switches from the locked state to the unlocked state.
[0012] Optionally, the locking device also includes a third elastic element, which is disposed on the mounting base and can contact the speaker body. In the unlocked state, the speaker body can move under the elastic force of the third elastic element, so that at least part of the speaker body is ejected from the mounting slot.
[0013] Optionally, the locking element is provided with a locking groove, and the speaker body is provided with a locking part, which can be engaged or disengaged from the locking groove.
[0014] Secondly, an audio device is provided, including an audio body and a locking device as described in the first aspect.
[0015] Thirdly, a vehicle is provided, including a vehicle body and an audio device as described in the second aspect, wherein the audio unit of the audio device is detachably mounted to the vehicle body by means of a locking device.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a locking device, an audio device, and a vehicle. When the state of the locking component needs to be switched, only the movement of the first linkage component is required to activate the first linkage component, which in turn drives the locking component via the second linkage component. This eliminates the need for a motor or other driving device, reducing the overall cost and failure rate of the locking device and improving its operability and reliability in emergency scenarios such as power outages. The first linkage component can also trigger the movement of a trigger component, which in turn moves a push component. When the locking component releases its hold on the audio device, the audio device can be moved a predetermined distance from the mounting slot under the pushing force of the push component, facilitating easy removal of the audio device by the user and improving the user experience.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.
[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0021] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0022] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.
[0023] Example 1 like Figures 1 to 9 As shown, this embodiment provides a locking device that improves the ease of operation, reduces the overall cost and failure rate, and ensures operability and reliability in emergency scenarios such as power outages.
[0024] See Figure 1 and Figure 2The locking device includes a mounting base 100, a locking member 200, a first linkage component 300, a second linkage component 400, a trigger component 500, and a pusher 600. The mounting base 100 has a mounting groove 111 into which the speaker body 10 can be installed. The locking member 200 is movably mounted on the mounting base 100 and has a locked state where it engages with the speaker body 10 and an unlocked state where it is released from engagement with the speaker body 10. Both the first linkage component 300 and the second linkage component 400 are movably mounted on the mounting base 100, and the second linkage component 400 is connected to the locking member 200. The pusher 600 is movably mounted on the mounting base. The device 100 can support at least part of the speaker body 10. The trigger component 500 is movably connected to the first linkage component 300 and the pusher 600. The first linkage component 300 is driven to move, and the first linkage component 300 moves to contact the second linkage component 400 and drives the second linkage component 400 to move. The second linkage component 400 drives the locking component 200 to switch from the locked state to the unlocked state. At the same time, the first linkage component 300 triggers the trigger component 500 to move. After the locking component 200 switches to the unlocked state, the trigger component 500 drives the pusher 600 to move. The pusher 600 pushes the speaker body 10 out of the mounting slot 111 by a preset distance.
[0025] The locking device provided in this embodiment only requires driving the first linkage component 300 to move when the state of the locking member 200 needs to be switched. This allows the first linkage component 300 to drive the locking member 200 through the second linkage component 400, eliminating the need for a motor or other driving equipment. This reduces the overall cost and failure rate of the locking device and improves its operability and reliability in emergency scenarios such as power outages. The first linkage component 300 can also trigger the trigger component 500 to move, causing the trigger component 500 to move the pusher component 600. When the locking member 200 releases its lock on the speaker body 10, the speaker body 10 can move a preset distance from the mounting slot 111 under the pushing force of the pusher component 600, making it easier for the user to remove the speaker body 10 from the mounting slot 111 and improving the user experience.
[0026] Furthermore, since it does not require the use of motors or other driving equipment, the locking device can still work stably in complex environments such as high temperature, vibration, and humidity, significantly improving its durability and market competitiveness.
[0027] In this embodiment, see Figure 1 and Figure 2 The pusher 600 is along the opening direction of the mounting groove 111 ( Figure 1 The speaker body 10 is movably disposed on the mounting base 100 in the Z direction. After the trigger component 500 is triggered, the pusher 600 pushes the speaker body 10 along the opening direction of the mounting groove 111 so that the speaker body 10 can be moved out of the mounting groove 111 by a preset distance.
[0028] For example, see Figure 1 and Figure 2 The mounting base 100 is a box, and the inner cavity of the box is the mounting groove 111, into which the speaker body 10 can be embedded.
[0029] Optionally, see Figure 1 , Figure 2 and Figure 3 The first linkage component 300 moves along the first direction ( Figure 1 The trigger assembly 500 is movably disposed on the mounting base 100 in the Z direction. It includes a trigger member 510 and a first elastic member 520. The trigger member 510 is positioned along the second direction (Z direction). Figure 1 The first elastic element 520 is disposed on the mounting base 100 and connected to the pusher 600 (in the X direction). When the locking element 200 is in the locked state, the trigger element 510 is engaged with the mounting base 100, and the first elastic element 520 accumulates elastic potential energy, driving the first linkage component 300 to move. The first linkage component 300 drives the trigger element 510 and the second linkage component 400 to move. The second linkage component 400 drives the locking element 200 to switch from the locked state to the unlocked state. The trigger element 510 moves until it is unengaged with the mounting base 100. After the locking element 200 switches to the unlocked state, the pusher 600 moves under the elastic force of the first elastic element 520 and pushes the speaker body 10 to move. The first direction and the second direction are set at an angle. This configuration allows the first linkage component 300 to automatically trigger the trigger component 500 when the user moves the first linkage component 300, and the pusher 600 to move automatically to push at least part of the speaker body 10 out of the mounting slot 111, making it easier for the user to remove the speaker body 10 from the mounting slot 111 and improving the user experience.
[0030] For example, the first direction is the opening direction of the mounting groove 111, and the second direction is perpendicular to the first direction.
[0031] For example, the first elastic element 520 is a spring.
[0032] In this embodiment, see Figure 1 , Figure 4 and 5The pusher 600 includes a connecting part 610 and a pusher plate 620 connected together. The trigger 510 is movably connected to the connecting part 610 along a second direction. The first elastic member 520 is disposed on the mounting base 100 and connected to the connecting part 610. The mounting base 100 is provided with a slot 611. The pusher plate 620 can fit against at least a part of the surface of the speaker body 10. When the locking member 200 is in the locked state, the trigger 510 is inserted into the slot 611. The first linkage component 300 is driven to move. The first linkage component 300 drives the trigger 510 to move until it is disengaged from the slot 611. When the locking member 200 switches to the unlocked state, the connecting part 610 moves under the elastic force of the first elastic member 520 and drives the pusher plate 620 to push the speaker body 10 to move. When the trigger 510 engages with the slot 611, it locks into the mounting base 100, preventing the connecting portion 610 from moving and thus restricting the movement of the pusher 600 as a whole. Even if the locking member 200 is unlocked at this time, the speaker body 10 will not move. When the trigger 510 disengages from the slot 611, the constraint of the mounting base 100 on the trigger 510 is released, and consequently, the constraint on the connecting portion 610 is also released. The connecting portion 610 can then move the pusher plate 620 to push the speaker body 10. Furthermore, while the connecting portion 610 moves the pusher plate 620, it can also move the trigger 510 along with it. The pusher plate 620 can fit against the surface of the speaker body 10, and this surface contact increases the contact area between the pusher plate 620 and the speaker body 10, which helps to improve stability during pushing.
[0033] Specifically, see Figure 4 and Figure 5 The trigger assembly 500 also includes a connecting seat 530 connected to the connecting part 610. The trigger member 510 is movably disposed on the connecting seat 530 along the second direction, and the trigger member 510 is connected to the connecting part 610 through the connecting seat 530. The trigger member 510 includes a trigger body 511, a snap-fit part 512, and an elastic part 513. Both the snap-fit part 512 and the elastic part 513 are disposed on the trigger body 511. The first linkage assembly 300 is movably connected to the trigger body 511. The elastic part 513 is connected to the connecting seat 530. The snap-fit part 512 can snap into the slot 611 under the elastic force of the elastic part 513.
[0034] For example, the elastic part 513 is a spring.
[0035] In some embodiments, see Figure 4 and Figure 5 The snap-fit part 512 is provided with a guide slope 5121. The extension direction of the guide slope 5121 is set at an angle to the second direction. The guide slope 5121 can guide the snap-fit part 512 to smoothly enter the slot 611.
[0036] In some embodiments, see Figure 1 and Figure 5 The mounting base 100 is provided with a groove, and the first linkage component 300, the trigger component 500 and the pusher 600 are all installed in the groove. A protective plate 124 is provided in the groove to seal the groove opening to prevent dust or impurities from entering the groove and affecting the movement of the first linkage component 300, the trigger component 500 and the pusher 600.
[0037] Specifically, see Figure 5 Card slot 611 is located on protection plate 124.
[0038] In some embodiments, see Figure 1 , Figure 2 and 4 The pusher 600 also includes an auxiliary plate 630, which is connected to the pusher plate 620. When the speaker body 10 moves a preset distance from the mounting slot 111, part of the auxiliary plate 630 protrudes relative to the mounting base 100. At this time, the user can move the pusher plate 620 by pulling the auxiliary plate 630. The pusher plate 620 pushes the speaker body 10 to move, and the distance the speaker body 10 moves from the mounting slot 111 increases, further improving the convenience for the user to take the speaker body 10 off the mounting base 100.
[0039] In this embodiment, see Figure 3 and Figure 4 The first linkage component 300 includes a first linkage member 310 and a second linkage member 320 connected together. The first linkage member 310 is slidably engaged with the trigger member 510. Driving the first linkage member 310 to move causes the second linkage member 320 to move along a first direction and causes the trigger member 510 to move along a second direction. When the second linkage member 320 moves to contact the second linkage component 400, it causes the second linkage component 400 to move. The trigger member 510 is released from the mounting base 100, and the pusher 600 moves under the elastic force of the first elastic member 520.
[0040] Specifically, see Figure 3 and Figure 4 Both the first linkage 310 and the second linkage 320 are rods, and the connecting part 610 is a tube. The connecting part 610 has an oblong hole 612 extending along the first direction. One end of the second linkage 320 is connected to the first linkage 310, and the other end passes through the oblong hole 612 and is connected to the second linkage assembly 400. The oblong hole 612 allows the second linkage 320 to connect to the first linkage 310, and the connecting part 610 does not affect the movement of the second linkage 320 along the first direction.
[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The mounting base 100 is provided with a second elastic element 112, which is connected to the second linkage element 320. The second linkage element 320 can drive the first linkage element 310 to move along the first direction under the elastic force of the second elastic element 112, so as to realize the automatic reset of the first linkage component 300 as a whole after the speaker body 10 is removed from the mounting slot 111.
[0042] For example, the second elastic element 112 is a tension spring.
[0043] In this embodiment, see Figure 1 , Figure 2 and Figure 4 The locking device also includes an operating member 700 movably disposed on the mounting base 100 along a first direction, and the operating member 700 is connected to the first linkage component 300. Pressing the operating member 700 causes the first linkage component 300 to move, thereby removing the speaker body 10 from the mounting slot 111, improving the convenience of operation.
[0044] For example, the operating component 700 uses an operating button.
[0045] In this embodiment, see Figure 4 The trigger 510 is provided with an inclined guide groove 5111, and the first linkage assembly 300 is provided with a sliding part 311, which slides in cooperation with the guide groove 5111. When the first linkage assembly 300 is driven to move in the first direction, the sliding part 311 can drive the trigger 510 to move in the second direction under the action of the groove wall of the guide groove 5111. The guide groove 5111 allows the trigger 510 to move in the second direction under the action of the first linkage assembly 300 when it moves in the first direction, so that the trigger 510 can be disengaged from the mounting base 100. The sliding part 311 reduces the friction between the first linkage assembly 300 and the trigger 510, reduces the resistance when the first linkage assembly 300 drives the trigger 510 to move, and improves the user experience.
[0046] Specifically, the inclination direction of the guide groove 5111 is set at an angle to both the first direction and the second direction. (See reference...) Figure 1 and Figure 4 In the orientation, the groove of the mounting slot 111 is located on the upper surface of the mounting base 100, and the locking member is located on the lower surface of the mounting base 100. The first direction is vertical, and the second direction is left and right. Pressing down on the first linkage component 300 causes it to slide relative to the guide groove 5111 and push against the groove wall of the guide groove 5111 to move to the left. The trigger member 510 moves to the left as a whole, and the trigger member 510 gradually disengages from the mounting base 100.
[0047] The sliding part 311 is located at the lower end of the first linkage 310, and the guide groove 5111 is located on the trigger body 511.
[0048] See Figure 1 , Figure 4 and Figure 5 In the orientation of the speaker body 10, when it is necessary to remove it from the mounting slot 111: Press down on the operating member 700, the operating member 700 drives the first linkage member 310 to move downward, the first linkage member 310 moves relative to the connecting part 610 and drives the second linkage member 320 to move downward, the second linkage member 320 gradually contacts the second linkage assembly 400 and drives the second linkage assembly 400 to move, the second linkage assembly 400 drives the locking member to move, and the locking member switches from the locked state to the unlocked state; at the same time, the sliding part 311 of the first linkage member 310 slides along the guide groove 5111, the sliding part 311 drives the trigger body 511 to move to the left, the locking part 512 gradually disengages from the slot 611, and the elastic part 513 deforms; after the locking part 512 disengages from the slot 611 and the locking member switches to the unlocked state, the push plate 620 moves upward under the elastic force of the first elastic member 520, and the push plate 620 drives the trigger member 510, the auxiliary plate 630 and the speaker body 10 to move upward, and the upper end of the speaker body 10 disengages from the mounting slot 111 by a preset distance; then, the auxiliary plate 630 is pulled upward, and the auxiliary plate 630 drives the speaker body 10 to further disengage from the mounting slot 111 through the push plate 620. After the speaker body 10 is removed from the mounting slot 111, the auxiliary plate 630 is pressed down. The auxiliary plate 630 drives the push plate 620 and the connecting part 610 to move down, and the first elastic member 520 deforms. When the connecting part 610 drives the snap-fit part 512 of the trigger member 510 to move to the slot 611, the snap-fit part 512 is snapped into the slot 611 under the elastic force of the elastic part 513, and the push plate 620 no longer moves.
[0049] Optionally, see Figure 1 , Figure 3 and Figure 6 Locking component 200 around a third party ( Figure 3The first linkage assembly 300 is rotatably mounted on the mounting base 100 in the X direction. The second linkage assembly 400 includes a third linkage member 410 and a fourth linkage member 420. Both the third linkage member 410 and the fourth linkage member 420 are rotatably mounted on the mounting base 100 in the X direction. One end of the third linkage member 410 is connected to one end of the fourth linkage member 420, and the other end of the fourth linkage member 420 is connected to the locking member 200. The first linkage assembly 300 is driven to move, and the first linkage assembly 300 moves to contact the third linkage member 410 and pushes the third linkage member 410 to rotate. The third linkage member 410 drives the fourth linkage member 420 to rotate, and the fourth linkage member 420 drives the locking member 200 to rotate. The locking member 200 switches from the locked state to the unlocked state. This configuration allows both the third linkage 410 and the fourth linkage 420 to function as levers, meaning that when one end moves, the other end moves in the opposite direction, thus achieving a linkage effect between the third linkage 410, the fourth linkage 420, and the locking element 200. Compared to existing technologies, the changes in the state of the locking element 200 are entirely achieved through purely mechanical linkages, eliminating the need for motors or other drive devices. This reduces the overall cost and failure rate of the locking device and improves its operability and reliability in emergency scenarios such as power outages.
[0050] In this embodiment, the third direction is parallel to the second direction; in other embodiments, the third direction is set at an angle to the second direction.
[0051] In this embodiment, see Figure 1 and Figure 6 The mounting base 100 is provided with a rotatable first connecting shaft 113, a rotatable second connecting shaft 114, and a rotatable third connecting shaft 115. The first connecting shaft 113, the second connecting shaft 114, and the third connecting shaft 115 all extend in a third direction. The first connecting shaft 113 passes through the third linkage member 410, the second connecting shaft 114 passes through the fourth linkage member 420, and the third connecting shaft 115 passes through the locking member 200, so as to realize the rotatable connection between the third linkage member 410, the fourth linkage member 420, the locking member 200, and the mounting base 100.
[0052] In some embodiments, see Figure 6A first torsion spring 116 is provided on the first connecting shaft 113, a second torsion spring 117 is provided on the second connecting shaft 114, and a third torsion spring 118 is provided on the third connecting shaft 115. When the locking member 200 switches from the locked state to the unlocked state, the first connecting shaft 113, the second connecting shaft 114, and the third connecting shaft 115 rotate, and the first torsion spring 116, the second torsion spring 117, and the third torsion spring 118 all accumulate elastic potential energy. The third connecting shaft 115 can rotate under the elastic force of the third torsion spring 118, and the third connecting shaft 115 drives the locking member 200 to switch from the unlocked state to the locked state. The second connecting shaft 114 rotates under the elastic force of the second torsion spring 117, and the first connecting shaft 113 rotates under the elastic force of the first torsion spring 116.
[0053] Specifically, when the speaker body 10 is removed from the mounting slot 111: see Figure 3 and Figure 6 In the center position, press down on the first linkage component 300. The first linkage component 300 gradually contacts the left end of the third linkage component 410 and pushes down on the left end of the third linkage component 410. The third linkage component 410 rotates and drives the first connecting shaft 113 to rotate, and the first torsion spring 116 deforms. The right end of the third linkage component 410 moves up, and the right end of the third linkage component 410 drives the left end of the fourth linkage component 420 to move up. The fourth linkage component 420 rotates and drives the second connecting shaft 114 to rotate, and the second torsion spring 117 deforms. The right end of the fourth linkage component 420 moves down, and the right end of the fourth linkage component 420 drives the locking component 200 to rotate. The locking component 200 switches from the locked state to the unlocked state. The third connecting shaft 115 rotates, and the third torsion spring 118 deforms. After the locking component 200 switches to the unlocked state, the third torsion spring 118 restores its deformation and drives the third connecting shaft 115 to rotate. The third connecting shaft 115 drives the locking component 200 to rotate, and the locking component 200 drives the right end of the fourth linkage component 420 to move upward. The second torsion spring 117 restores its deformation and drives the second connecting shaft 114 to rotate. The second connecting shaft 114 drives the fourth linkage component 420 to rotate, and the left end of the fourth linkage component 420 moves downward. The left end of the fourth linkage component 420 drives the right end of the third linkage component 410 to move downward. The first torsion spring 116 restores its deformation and drives the first connecting shaft 113 to rotate. The first connecting shaft 113 drives the third linkage component 410 to rotate, and the left end of the third linkage component 410 moves upward. The third linkage component 410 pushes the first linkage assembly 300 to move upward.
[0054] In this embodiment, see Figure 3 The first linkage component 300 includes a first linkage member 310 and a second linkage member 320 connected together. The first linkage member 310 is driven to move, and the first linkage member 310 drives the second linkage member 320 to move to contact the third linkage member 410 and push the third linkage member 410 to rotate.
[0055] In some embodiments, see Figure 3 The second linkage 320 is provided with a contact portion 321, and the contact portion 321 is provided with an arc-shaped surface, which drives the first linkage 310 to move. The first linkage 310 drives the second linkage 320 to move, and the arc-shaped surface contacts and rotates with the third linkage 410. The arc-shaped surface can reduce the friction between the second linkage 320 and the third linkage 410 and prevent the second linkage 320 from affecting the rotation of the third linkage 410.
[0056] Specifically, see Figure 3 The cross-sectional shape of the contact portion 321 is circular, and the arc-shaped surface is the outer surface of the contact portion 321.
[0057] In this embodiment, see Figure 1 , Figure 2 and Figure 3 There are two locking components 200 and two sets of second linkage components 400. The two sets of second linkage components 400 are connected to the two locking components 200 one-to-one. The two locking components 200 are symmetrically arranged on the mounting base 100. This arrangement helps to improve the firmness of the locking components 200 in locking the speaker body 10 and ensures the uniformity of the locking force on the speaker body 10, thus preventing damage to the speaker body 10.
[0058] Specifically, see Figure 3 There are two second linkage components 320. Both second linkage components 320 are connected to the first linkage component 310 and correspond one-to-one with the two sets of second linkage components 400.
[0059] Optionally, see Figure 1 and Figure 2 The locking device also includes a third elastic element 800, which is disposed on the mounting base 100 and can contact the speaker body 10. In the unlocked state, the speaker body 10 can move under the elastic force of the third elastic element 800, so that at least part of the speaker body 10 pops out of the mounting groove 111. The third elastic element 800 allows part of the speaker body 10 to pop out of the mounting groove 111 in the unlocked state, and a gap can be formed between the speaker body 10 and the groove wall of the mounting groove 111. Then, the gravity of the speaker body 10 acts on the pusher 600, so that the pusher 600 can further push the speaker body 10 to move. This not only further improves the convenience of operation, but also effectively avoids accidental damage to the speaker body 10 when it is removed, and extends the service life of the speaker body 10.
[0060] See Figure 1 and Figure 3When the speaker body 10 is removed from the mounting slot 111, after the locking member 200 switches to the unlocked state, the third elastic member 800 first pops the speaker body 10 out of the mounting slot 111 a certain distance; then, the pushing member 600 pushes the speaker body 10 out of the mounting slot 111 a preset distance.
[0061] Specifically, see Figure 1 The groove of the mounting slot 111 is located on the first surface of the mounting base 100, and the third elastic member 800 is disposed on the second surface of the mounting base 100. The first and second surfaces are two surfaces directly opposite each other of the mounting base 100, and the elastic force direction of the third elastic member 800 is the opening direction of the groove of the mounting slot 111. This arrangement allows the elastic force of the third elastic member 800 to be fully used to drive the movement of the speaker body 10, improving the utilization rate of the elastic force.
[0062] For example, the third elastic element 800 is a spring.
[0063] In this embodiment, see Figure 1 Multiple third elastic elements 800 are provided, and the multiple third elastic elements 800 are arranged at intervals along the circumference of the speaker body 10 so that the speaker body 10 can be subjected to uniform elastic force, and thus can be popped out of the mounting groove 111 stably as a whole.
[0064] In this embodiment, see Figure 1 and Figure 7 The mounting base 100 is provided with a mounting hole that communicates with the mounting groove 111. A connector 119 is provided in the mounting hole. A third elastic member 800 is provided on the connector 119. The locking device also includes a pusher 120 that is movably provided on the connector 119. The pusher 120 is connected to the third elastic member 800 and can contact the speaker body 10. In the unlocked state, the pusher 120 moves under the elastic force of the third elastic member 800 and pushes the speaker body 10 to move, so as to realize the automatic pop-out of the speaker body 10 in the unlocked state.
[0065] Optionally, see Figure 2 , Figure 6 and Figure 8 The locking member 200 is provided with a locking groove 210, and the speaker body 10 is provided with a locking part 11. The locking part 11 can engage or disengage from the locking groove 210. When the locking part 11 is engaged in the locking groove 210, the locking member 200 is in a locked state, and the speaker body 10 can be stably installed in the mounting groove 111. When the locking part 11 disengages from the locking groove 210, the locking member 200 is in an unlocked state. At this time, the speaker body 10 can be removed from or installed in the mounting groove 111, which is convenient and quick to operate and improves the user experience.
[0066] For example, see Figure 8The locking part 11 adopts a shaft.
[0067] In this embodiment, the locking member 200 is rotatably disposed on the mounting base 100 in a third direction. When the locking member 200 rotates, the locking part 11 can be engaged or disengaged from the locking groove 210.
[0068] Optionally, see Figure 1 and Figure 2 A flexible pad 121 is provided on the wall of the mounting groove 111, allowing the speaker body 10 to contact the flexible pad 121. This arrangement helps increase the friction between the speaker body 10 and the wall of the mounting groove 111, preventing the speaker body 10 from moving or bumping within the mounting groove 111, extending the service life of the speaker body 10, and improving the stability of the speaker body 10 during installation. Furthermore, the flexible pad 121 can absorb the vibration energy of the mounting base 100, reducing resonance and noise transmission, and improving the sound quality output by the speaker body 10.
[0069] For example, the flexible pad 121 is made of a flexible material such as rubber.
[0070] Optionally, see Figure 1 The mounting base 100 is provided with a vibration damping element 123, which is in contact with the external structure and is used to reduce the transmission of noise by stopping the vibration energy generated when the locking structure moves, thereby improving the quality of the sound output of the speaker body 10 and also improving the stability of the speaker body 10 when mounted on the external structure.
[0071] For example, the damper 123 is made of a flexible material such as rubber.
[0072] Optionally, see Figure 1 , Figure 8 and Figure 9 The speaker body 10 is provided with a charging port 12, and the mounting base 100 is provided with a connection port 122. When the speaker body 10 is installed in the mounting slot 111, the connection port 122 is connected to the charging port 12. An external power source can be connected to the charging port 12 through the connection port 122 to realize the transmission of power and signal between the external structure and the speaker body 10.
[0073] Example 2 like Figures 1 to 9 As shown, this embodiment provides an audio device, including an audio body 10 and a locking device as described in Embodiment 1.
[0074] This locking device not only stably and reliably supports the speaker body, preventing damage and providing protection, but also makes it easy for users to remove the speaker body 10 from the mounting slot 111, improving the user experience.
[0075] Example 3 like Figures 1 to 10 As shown, this embodiment provides a vehicle, including a vehicle body 20 and an audio device of embodiment two. The audio device's audio body 10 is detachably mounted to the vehicle body 20 via a locking device.
[0076] When the user wants to remove the audio unit 10 from the vehicle body 20, they only need to press the operating part 700, which can be used for one-handed operation while driving, improving the convenience of operation and driving safety.
[0077] The mounting base 100 is installed on the vehicle body 20, and the audio unit 10 is electrically connected to the vehicle body 20.
[0078] In this embodiment, see Figure 1 and Figure 10 The mounting bracket 100 is installed in the trunk of the vehicle body 20. Specifically, an installation space 21 is provided on the outer wall of the vehicle body 20 opposite to the trunk position. The mounting bracket 100 is installed in the installation space 21, and the surface of the mounting bracket 100 is flush with the outer wall of the vehicle body 20, so that the user can quickly remove the audio unit from the vehicle body 20, and also ensures the aesthetics of the vehicle body 20.
