[0010] A push rod is connected to a first buckle, and the push rod is provided with a first receiving groove for accommodating the protrusion of the central control screen housing;

[0011] The first elastic element is located in the first receiving groove. One end of the first elastic element is used to drive the protrusion to abut against the end of the first receiving groove near the second buckle, so that the push rod drives the first buckle away from the second buckle.

[0012] In one possible implementation, the push rod assembly further includes a guide mechanism, which includes:

[0013] A guide hole is formed in the push rod, and the length direction of the guide hole is parallel to the first direction.

[0014] A guide component is connected to the housing of the central control screen. The guide component is located inside the guide hole and can slide relative to the guide hole in a first direction.

[0015] In one possible implementation, the first buckle has a first inclined surface on the side facing the first slot, and the angle between the first inclined surface and the first direction is within the range of (0 degrees, 90 degrees). The first inclined surface is used to abut against the side of the first slot facing the first buckle when the male and female fasteners move towards each other to drive the push rod to move toward the second buckle.

[0016] In one possible implementation, the push rod is provided with a pressing part located at the end of the push rod away from the second buckle, and the central control screen housing is provided with a third through hole extending in the first direction, through which the pressing part passes.

[0017] In one possible implementation, the first buckle includes at least two first buckle bodies, which are spaced apart in a second direction, perpendicular to the first direction, and perpendicular to the direction in which the male and female buckles move toward each other.

[0018] In one possible implementation, the central control screen housing has a first through hole for accommodating the second buckle. The first through hole has guide slopes on both sides in the second direction, so that the first through hole has an flared structure facing the female buckle. The second direction is perpendicular to the first direction and is perpendicular to the direction in which the male buckle and the female buckle move towards each other.

[0019] In one possible implementation, the second latch is movably connected to the central control screen housing via a fixing component, the fixing component including:

[0020] A fixing bracket is connected to the side of the central control screen housing away from the female fastener. The fixing bracket is provided with a second receiving groove, which is used to receive the fixing part of the second buckle.

[0021] The second elastic member is located in the second receiving groove. One end of the second elastic member is used to drive the fixing part to abut against the end of the second receiving groove away from the first buckle, so that the second buckle moves away from the first buckle in the first direction to press against the second buckle groove.

[0022] In one possible implementation, the second buckle has a second inclined surface on the side facing the second slot, and the angle between the second inclined surface and the first direction is within the range of (0 degrees, 90 degrees).

[0025] By providing a second and a first latch spaced apart in a first direction on the male fastener, and a first and a second latch on the female fastener, when the male and female fasteners move towards each other, the second latch engages with the second latch and the first latch engages with the first latch, thus connecting the male and female fasteners. A push rod assembly is fixedly connected to the first latch and can move in the first direction to synchronously drive the first latch to move in the first direction. After the male and female fasteners engage, the push rod assembly drives the first latch away from the second latch in the first direction to press against the first latch, maintaining the engagement between the first latch and the first latch. This allows the central control screen housing to be fixed relative to the fixing device. When the male and female fasteners need to be separated, the push rod assembly can be driven by external force to move towards the second buckle, causing the first buckle to disengage from the first slot. Then, the male fastener can be driven to move away from the female fastener. During the connection and disassembly of the male and female fasteners, the push rod assembly can be used to move the first buckle in the first direction, which can realize the quick installation and disassembly of the male and female fasteners. This facilitates the quick installation and disassembly of the central control screen and effectively improves the problem of the central control screen being dropped due to collision caused by magnetic attraction in the existing technology.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of this utility model, it should be understood that the terms "upper", "lower", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position 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 of this utility model.

[0041] The purpose of this invention is to provide a snap-on quick-release device that facilitates the rapid installation and removal of the central control screen while effectively improving the problem of the central control screen being knocked off by collisions due to magnetic attraction in the prior art.

[0042] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0043] Please see Figures 1 to 5 To achieve the above objectives, this utility model provides a quick-release buckle device, including a male buckle, a female buckle 300, and a push rod assembly 400. The male buckle is used to connect with the central control screen housing 100, and includes a first buckle 210 and a second buckle 220 spaced apart in a first direction. The female buckle 300 is used to be fixedly connected to a fixing device, which can be, but is not limited to, a wall or a seat. The female buckle 300 is provided with a first slot 310 detachably connected to the first buckle 210 and a second slot 320 detachably connected to the second buckle 220. The push rod assembly 400 is fixedly connected to the first buckle 210 and can move in the first direction. After the male buckle and the female buckle 300 move towards each other, causing the first buckle 210 to engage with the first slot 310 and the second buckle 220 to engage with the second slot 320, the push rod assembly 400 drives the first buckle 210 away from the second buckle 220 in the first direction to press against the first slot 310. The first direction can be any direction within the vertical plane, including but not limited to the horizontal direction and the height direction. For example, when the first buckle 210 is arranged on the left side of the central control screen housing 100, the second buckle 220 is arranged on the right side of the central control screen housing 100; when the first buckle 210 is arranged on the lower part of the central control screen housing 100, the second buckle 220 is arranged on the upper part of the central control screen housing 100.

[0044] By providing a second latch 220 and a first latch 210 spaced apart in a first direction on the male fastener, and a first slot 310 and a second slot 320 on the female fastener 300, when the male and female fasteners 300 move toward each other, the second latch 220 engages with the second slot 320 and the first latch 210 engages with the first slot 310, thus connecting the male and female fasteners 300. The push rod assembly 400 is fixedly connected to the first latch 210 and can move in the first direction to synchronously drive the first latch 210 to move in the first direction. After the male and female fasteners 300 are engaged, the push rod assembly 400 drives the first latch 210 away from the second latch 220 in the first direction to press against the first slot 310, thus connecting the first latch 210. The male and female fasteners 300 are engaged with the first slot 310, thus fixing the central control screen housing 100 relative to the fixing device. When the male and female fasteners 300 need to be separated, the push rod assembly 400 is driven by external force to move toward the second fastener 220, so that the first fastener 210 is disengaged from the first slot 310. Then, the male fastener is driven to move away from the female fastener 300. During the connection and disassembly of the male and female fasteners 300, the push rod assembly 400 is used to drive the first fastener 210 to move in the first direction, which can realize the quick installation and disassembly of the male and female fasteners 300. This facilitates the quick installation and disassembly of the central control screen and effectively improves the problem of the central control screen being dropped due to collision caused by magnetic attraction in the prior art.

[0045] The second buckle 220 can be fixedly connected to the central control screen housing 100. By setting the second buckle 220 in a fixed position on the central control screen housing 100, during the connection of the male and female fasteners 300, the second buckle 220 can be engaged with the second slot 320 first, and then the first buckle 210 and the first slot 310 can be engaged, further simplifying the mechanism and saving costs and internal layout space. In addition, when the second buckle 220 is fixedly connected to the central control screen housing 100, at least part of the second buckle 220 is made of elastic material, so that the second buckle 220 can easily deform and recover during the installation and removal of the male and female fasteners 300, which facilitates installation and improves the service life of the second buckle 220.

[0046] In one possible implementation, the push rod assembly 400 includes a push rod 410 and a first elastic member 420. The push rod 410 is connected to a first latch 210 and has a first receiving groove 411 for receiving a protrusion 110 of the central control screen housing 100. The first elastic member 420 is located in the first receiving groove 411, and one end of the first elastic member 420 is used to drive the protrusion 110 to abut against the end of the first receiving groove 411 near the second latch 220, so that the push rod 410 drives the first latch 210 away from the second latch 220.

[0047] It should be noted that the first receiving groove 411 has a first protrusion at the end opposite to the second buckle 220, and the protrusion 110 has a second protrusion at the end facing the first protrusion. One end of the first elastic member 420 is connected to the first protrusion and the other end is connected to the second protrusion. The first elastic member 420 can be, but is not limited to, a compression spring. In the unforced state, the length of the compression spring in the first direction is greater than or equal to the length of the first receiving groove 411 in the first direction, so that the compression spring is always in a compressed state when installed in the first receiving groove 411, driving the protrusion 110 to move away from the first protrusion, that is, driving the protrusion 110 to abut against the end of the first receiving groove 411 near the second buckle 220, so that the push rod 410 drives the first buckle 210 to engage with the second buckle 220. The latch 220 maintains the furthest distance in the first direction. When the male and female fasteners 300 need to be engaged, the first latch 210 can be moved toward the second latch 220 in the first direction by the drive push rod 410 to further compress the compression spring. At this time, the distance between the first latch 210 and the second latch 220 in the first direction is small. After the second latch 220 is engaged with the second slot 320, the external force is removed. Under the action of the restoring force of the further compressed compression spring, the push rod 410 moves toward the direction away from the second latch 220 to engage with the first slot 310. The force that drives the push rod 410 to compress the compression spring can be either the squeezing force of the male and female fasteners 300 moving toward each other or the external force acting directly on the push rod 410.

[0048] In one possible implementation, the push rod assembly 400 further includes a guide mechanism, which includes a guide hole 412 and a guide member 430. The guide hole 412 is formed in the push rod 410, and the length direction of the guide hole 412 is parallel to the first direction. The guide member 430 is connected to the central control screen housing 100, the guide member 430 is located in the guide hole 412, and the guide member 430 is slidable relative to the guide hole 412 in the first direction. The guide member 430 is connected to the central control screen housing 100 via a connector, which can be, but is not limited to, screws or pins. When the guide hole 412 only serves a guiding function, the length of the guide hole 412 in the first direction should be greater than or equal to the maximum stroke of the push rod 410 in the first direction. When the guide hole 412 is also used to limit the movement of the push rod 410 in the first direction, the end of the guide hole 412 near the second latch 220 can be used as the limit position for the push rod 410 to move toward the second latch 220, and the end of the guide hole 412 away from the second latch 220 can be used as the limit position for the push rod 410 to move away from the second latch 220. Through the sliding engagement of the guide member 430 and the guide hole 412, the movement of the push rod 410 can be guided, effectively preventing the push rod 410 from deviating or wobbling under force.

[0049] In one possible implementation, the first buckle 210 has a first inclined surface 230 on the side facing the first slot 310. The angle between the first inclined surface 230 and the first direction is within the range of (0 degrees, 90 degrees). The first inclined surface 230 is used to abut against the side of the first slot 310 facing the first buckle 210 when the male and female fasteners 300 move towards each other to drive the push rod 410 to move toward the second buckle 220. It is understandable that, with the first inclined surface 230 provided on the side of the first buckle 210 facing the first slot 310, when the male and female fasteners 300 move towards each other, the first inclined surface 230 contacts the first slot 310 before the rest of the first buckle 210. Under the push of the outer wall of the first slot 310, the first inclined surface 230 of the first buckle 210 moves toward the second buckle 220 to compress the first elastic member 420. A third inclined surface parallel to the first inclined surface 230 can be provided in the area of ​​the outer wall of the first slot 310 that contacts the first inclined surface 230. This increases the contact area when the outer wall of the first slot 310 presses the first inclined surface 230 of the first buckle 210, thereby reducing the wear when the outer wall of the first slot 310 presses the first inclined surface 230 of the first buckle 210 and improving the service life of the first slot 310 and the first buckle 210.

[0050] In one possible implementation, the push rod 410 is provided with a pressing part 413, which is located at the end of the push rod 410 away from the second buckle 220. The central control screen housing 100 is provided with a third through hole extending in the first direction. The pressing part 413 passes through the third through hole. By driving the pressing part 413 to move in the first direction, the push rod 410 and the first buckle 210 can be driven to move as a whole in the first direction, which facilitates the connection and separation of the male fastener and the female fastener 300 and improves the user experience.

[0051] In one possible implementation, the first buckle 210 includes at least two first buckle bodies 211, which are spaced apart in a second direction. The first slot 310 includes a first slot body that corresponds one-to-one with the first buckle bodies 211. The second direction is perpendicular to the direction in which the male and female fasteners 300 move toward each other. The first buckle 210 also includes a first main structure connecting the two first buckle bodies 211. The first main structure is fixedly connected to the push rod 410. The movement of the push rod 410 in the first direction can drive the first main structure and the two first buckle bodies 211 to move synchronously in the first direction. The two first buckle bodies 211 engage with the first slot bodies at different positions, which can realize the fixing of the male and female buckles 300 at different positions and improve the stability of the male and female buckles 300 after connection. The first buckle bodies 211 and the second buckle 220 should be arranged in a ring to effectively improve the stability of the male and female buckles 300 after engagement. The number of first buckle bodies 211 can be increased or decreased according to actual needs to adapt to different usage scenarios.

[0052] In one possible implementation, the central control screen housing 100 has a first through hole for accommodating the second buckle 220. The first through hole has guide slopes 120 on both sides in a second direction, so that the first through hole has an flared structure facing the female buckle 300. The second direction is perpendicular to the direction in which the male buckle and the female buckle 300 move towards each other. By setting the flared structure, it can play a role in assisting guidance and positioning. Specifically, when the male buckle moves towards the female buckle 300 and the second slot 320 enters the flared structure, it indicates that the second slot 320 and the second buckle 220 are roughly aligned. Then, by applying external force, the male buckle continues to move towards the female buckle 300, and the second slot 320 and the second buckle 220 are engaged.

[0053] In one possible implementation, the second buckle 220 is movably connected to the central control screen housing 100 via a fixing component 500. The fixing component 500 includes a fixing frame 510 and a second elastic member 520. The fixing frame 510 is connected to the side of the central control screen housing 100 away from the female buckle 300. The fixing frame 510 and the central control screen housing 100 are connected by a fixing member, which can be, but is not limited to, screws or pins. The fixing frame 510 is provided with a second receiving groove 511 for receiving the fixing part of the second buckle 220. The second elastic member 520 is located in the second receiving groove 511. One end of the second elastic member 520 is used to drive the fixing part to abut against the end of the second receiving groove 511 away from the first buckle 210, so that the second buckle 220 moves away from the first buckle 210 in a first direction to press against the second buckle groove 320.

[0054] It should be noted that the second receiving groove 511 has a third protrusion at one end near the first buckle 210, and the fixing part has a fourth protrusion at one end facing the third protrusion. One end of the second elastic member 520 is connected to the third protrusion and the other end is connected to the fourth protrusion. The second elastic member 520 can be, but is not limited to, a compression spring. In the unforced state, the length of the compression spring in the first direction is greater than or equal to the length of the second receiving groove 511 in the first direction, so that the compression spring is always in a compressed state when installed in the second receiving groove 511, driving the fixing part to move away from the third protrusion. That is, driving the fixing part to abut against the end of the second receiving groove 511 away from the first buckle 210, so that the second buckle 220 and the first buckle 210 are in contact. 0. Maintaining the furthest distance in the first direction, when the male and female fasteners 300 need to engage, the second fastener 220 is driven to move toward the first fastener 210 in the first direction to further compress the spring. At this time, the distance between the first fastener 210 and the second fastener 220 in the first direction is small. When the second fastener 220 and the second slot 320 can no longer move toward each other, the second fastener 220 moves toward the direction away from the first fastener 210 under the restoring force of the further compressed spring to engage with the second slot 320. The force compressing the spring can be either the squeezing force of the male and female fasteners 300 moving toward each other or an external force acting directly on the spring or the second fastener 220.

[0055] In one possible implementation, the second buckle 220 has a second inclined surface 240 on the side facing the second slot 320. The angle between the second inclined surface 240 and the first direction is within the range of (0 degrees, 90 degrees). The second inclined surface 240 is used to abut against the side of the second slot 320 facing the second buckle 220 when the male and female fasteners 300 move towards each other to drive the second buckle 220 to move towards the first buckle 210. It is understandable that, with the second inclined surface 240 provided on the side of the second buckle 220 facing the second slot 320, when the male and female fasteners 300 move towards each other, the second inclined surface 240 contacts the second slot 320 before the rest of the second buckle 220. Under the push of the outer wall of the second slot 320, the second inclined surface 240 of the second buckle 220 is pressed and moves toward the first buckle 210 to compress the second elastic member 520. A fourth inclined surface parallel to the second inclined surface 240 can be provided in the area of ​​the outer wall of the second slot 320 that contacts the second inclined surface 240. This increases the contact area when the outer wall of the second slot 320 presses the second inclined surface 240 of the second buckle 220, thereby reducing the wear when the outer wall of the first slot 310 presses the second inclined surface 240 of the second buckle 220 and improving the service life of the second slot 320 and the second buckle 220.

[0056] In one possible implementation, the second latch 220 includes at least two second latch bodies, which are spaced apart in a second direction. The second latch 320 includes second latch bodies that correspond one-to-one with the second latch bodies, and the second direction is perpendicular to the direction in which the male and female fasteners 300 move towards each other. The two second latch bodies engage with second latch bodies at different positions, enabling the male and female fasteners 300 to be fixed at different locations. The second latch bodies and the first latch 210 should be arranged in a ring to effectively improve the stability of the male and female fasteners 300 after engagement. The number of second latch bodies can be increased or decreased according to actual needs to adapt to different usage scenarios.

[0057] In summary, this application provides a quick-release buckle device that enables the installation and removal of a central control screen from a fixing device. The specific process of installing the central control screen to the fixing device using the quick-release buckle device involves: grasping the central control screen (including the central control screen housing 100) with both hands; using the flared structure formed by the guide slope 120 for assisted positioning; and forcefully pushing the central control screen towards the fixing device. Under the pushing force, the second buckle 220 contacts the second slot 320, compressing the second elastic element 520. When the second buckle 220 reaches the inside of the second slot 320, the second... Under the rebound force of the second elastic element 520, the second buckle 220 is pushed into the second slot 320. Similarly, under the pushing force, the first buckle 210 contacts the first slot 310 and compresses the first elastic element 420. When the first buckle 210 reaches the inside of the first slot 310, under the rebound force of the first elastic element 420, the first buckle 210 is pushed into the first slot 310, realizing the engagement of the male and female buckles 300, thereby fixing the central control screen housing 100 relative to the fixing device. This mechanism is simple, using the elasticity of the first elastic element 420 and the second elastic element 520 to achieve the mutual engagement and guiding positioning of the buckles and slots, without the need for additional magnets to assist in positioning.

[0058] The process of disassembling the central control screen from the fixing device using the quick-release buckle device is as follows: one hand grasps the central control screen (including the central control screen housing 100), and the other hand presses the push rod 410 to compress the first elastic element 420, causing the first buckle 210 to disengage from the first slot 310. The central control screen is then grasped and slightly flipped, causing the first buckle 210 to move away from the first slot 310. Then, by translating the central control screen, the second buckle 220 can disengage from the second slot 320, thus realizing the function of disengaging the central control screen from the fixing device. The solution is simple, utilizing the elasticity of the first elastic element 420 and the second elastic element 520 to disengage the buckle from the slot, and then slightly flipping the central control screen to achieve complete disengagement. This can be achieved without magnets. No need for multiple pairs of magnets to assist in positioning; the guide slope 120 of the central control screen can be used to achieve assisted positioning, saving costs and internal space. At the same time, the push rod 410 and the compression spring work together to directly drive the first buckle 210 to move up and down in the first direction.
