Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a combination snap-fit. Background Technology

[0002] With the significant increase in car ownership, more and more businesses are developing and selling external devices that can add new functions to cars, aiming to improve the driving experience and comfort for consumers. Although external car devices come in a variety of styles, most of them are fixed to the car body using screws.

[0003] The connector is an external device, and the connecting plate is the car body.

[0004] However, the vibrations generated during vehicle operation can cause relative displacement between the connector and the contact surface when the vibrations are transmitted to the connector mounted on the connecting plate. This leads to the gradual loosening of the screws, resulting in the loss of the bolt connection function and causing the connector to fall off the connecting plate. Furthermore, the screw fixing method requires tools to complete the installation, making the installation process cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide a combined snap-fit ​​that reduces the impact of vehicle vibration on the connection effect and is easy to install.

[0006] The technical solution adopted by the combined buckle disclosed in this invention is:

[0007] For use in connecting a connector and a connecting plate, the device includes a snap-fit ​​component and a connector. The connector has a through hole. The connector and the connector are detachably connected. The snap-fit ​​component is bent to form a cavity. Both ends of the snap-fit ​​component have hanging ears that snap into the edge of one end of the through hole. A limiting piece extends from the outside of the snap-fit ​​component and touches the edge of the other end of the through hole. The snap-fit ​​component is provided with a spring piece that touches the connecting plate.

[0008] As a preferred embodiment, the system also includes a cover plate, which has a first protrusion that is fixed into the cavity. The first protrusion has a hook that engages with the edge of the other end of the through hole.

[0009] As a preferred embodiment, the connecting seat has a recessed groove that communicates with the through hole. The width of the recessed groove is greater than the width of the through hole. The cover plate is placed inside the recessed groove, and the lug is engaged with the bottom of the recessed groove.

[0010] As a preferred embodiment, the sinker is provided with a protrusion that touches the cover plate, the sinker is provided with a positioning groove, the positioning groove is located near the edge of one end of the through hole, and the hanging ear is provided with a recess that is engaged in the positioning groove for fixation.

[0011] As a preferred embodiment, the snap-fit ​​component has a notch, and the spring piece is located within the notch.

[0012] As a preferred embodiment, one end of the spring sheet extends into a horn, and a first contact piece extends from one side of one end of the spring sheet, the first contact piece and the horn contacting a connecting plate.

[0013] As a preferred embodiment, a second contact piece extends from one side of one end of the first contact piece, and the second contact piece touches the connecting plate.

[0014] As a preferred embodiment, the connecting seat extends with a second protrusion, the other end of the through hole passes through the second protrusion, a limiting part is provided on the outer side of the second protrusion, the connecting seat is provided with a sliding groove, a limiting groove is provided in the sliding groove, the second protrusion slides into the sliding groove, and the limiting part is engaged in the limiting groove for fixed connection.

[0015] As a preferred embodiment, the second protrusion has a contact surface corresponding to the limiting piece, the contact surface being close to the edge of the other end of the through hole, and the top of the limiting piece touching the contact surface.

[0016] The beneficial effects of the combined buckle disclosed in this invention are:

[0017] The connector is an external device, and the connecting plate is the vehicle body. The connector and the connecting plate are detachably connected, allowing the external device to be fixed to the connecting plate. The snap-fit ​​component is placed in a through hole on the connecting plate. The snap-fit ​​component is secured to both ends of the through hole by the lugs and limiting pieces on the snap-fit ​​component, thus fixing the snap-fit ​​component to the connecting plate. The snap-fit ​​component passes through the connecting plate, and a spring contact contacts the side of the connecting plate away from the connecting plate, thus firmly fixing the external device to the vehicle body via the connecting plate and the snap-fit ​​component. The snap-fit ​​method makes installation easier and can be done without auxiliary tools. Because this solution uses a snap-fit ​​connection method with a spring contact contacting the connecting plate, it reduces vibration during vehicle operation and reduces the tightening force of the snap-fit.

[0027] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0028] Example 1, please refer to Figures 1-3 .

[0029] The present invention discloses a combined buckle. In this embodiment, the connecting seat 11 is preferably an external device and the connecting plate 21 is a car body.

[0030] Furthermore, it includes a connector 31, a snap-fit ​​component 41, and a cover plate 51.

[0031] Please refer to Figure 1 and Figure 7 .

[0032] The connecting seat 11 is detachably connected to the outer side of the connecting seat 31. A through hole 32 is formed on the connecting seat 31, and a recessed groove 33 is formed on the connecting seat 31, communicating with the through hole 32. The width of the recessed groove 33 is greater than the width of the through hole 32, so that the cross-sections of the recessed groove 33 and the through hole 32 form a step. A protrusion 331 is provided inside the recessed groove 33; preferably, four protrusions 331 are located in four directions within the recessed groove 33, and the protrusions 331 are placed at the bottom of the recessed groove 33. A positioning groove 332 is formed inside the recessed groove 33; preferably, two positioning grooves 332 are provided in this embodiment, and the positioning grooves 332 are arc-shaped. The positioning grooves 332 are located at the bottom of the recessed groove 33, and are near the edge of one end of the through hole 32.

[0033] In this embodiment, the snap-fit ​​component 41 is preferably formed by stamping a single sheet of sheet metal and bending it into a V-shaped structure. The snap-fit ​​component 41 forms a cavity 411 inside through bending. Both ends of the snap-fit ​​component 41 extend with a lug 42. A recess 421 is formed on one side of the lug 42. When the recess 421 is recessed inward on one side of the lug 42, a protrusion is formed on the other side of the lug 42. A limiting piece 43 extends outward from the snap-fit ​​member 41. In this embodiment, two limiting pieces 43 are preferably formed by the snap-fit ​​member 41 during stamping. The two limiting pieces 43 are located on both sides of the snap-fit ​​member 41, and the connection points between the two limiting pieces 43 and the snap-fit ​​member 41 are close to the two ends of the snap-fit ​​member 41, respectively. The connection points between the limiting pieces 43 and the snap-fit ​​member 41 are located in the middle of the snap-fit ​​member 41. The connection points between the limiting pieces 43 and the snap-fit ​​member 41 are bent at a certain angle, so that the middle part and one end of the limiting pieces 43 are close to the two ends of the snap-fit ​​member 41, respectively. This allows the lug 42 to form a clamping area with the limiting pieces 43, which is used to limit the snap-fit ​​member within the through hole 32.

[0034] The snap-fit ​​component 41 is provided with spring tabs 44, and in this embodiment, two spring tabs 44 are preferably provided. One end of the spring tab 44 is inclined outward, and the other end of the spring tab 44 is close to the bend of the snap-fit ​​component 41. The two spring tabs 44 are symmetrical to each other.

[0035] By squeezing the two ends of the snap fastener 41, the elasticity of the snap fastener 41 reduces the distance between the two ends, allowing the two lugs 42 to pass through the through hole 32. After releasing the snap fastener 41, its elasticity causes the two lugs 42 to slide to the bottom of the recess 33 and engage with it. By positioning the limiting piece 43 close to the lugs 42, the connecting seat 31 is engaged between the lugs 42 and the limiting piece 43, making the engagement between the snap fastener 41 and the connecting seat 31 more secure.

[0036] Both limiting pieces 43 abut against the edge of the other end of the through hole 32. This abutting method ensures even force distribution on both sides of the latching member 41. Through the latching of the two hooks 42 and the abutting of the two limiting pieces 43 against the connecting seat 31, the latching member 41 is detachably latched into the through hole 32. The clamping force formed between the hooks 42 and the limiting pieces 43 firmly latches the latching member 41 into the through hole 32, restricting its sliding towards both ends of the through hole 32. The protrusion formed by the recess 421 on the hook 42 engages in the positioning groove 332, positioning the latching member 41 within the through hole 32 and reducing its wobbling within the through hole 32.

[0037] The cover plate 51 is provided with a first protrusion 511, and the first protrusion 511 is provided with a hook 512. In this embodiment, two hooks 512 are preferably provided, and the two hooks 512 are respectively located on both sides of one end of the first protrusion 511. One side of one end of the hook 512 is provided with an angle, and the angles of the two hooks 512 are far apart from each other, and the two hooks 512 are symmetrical to each other.

[0038] By pushing the cover plate 51, the angled hooks 512 deform by contacting the edge of one end of the through hole 32, causing the two hooks 512 to slide on the inner wall of the through hole 32. The two hooks 512 pass through the through hole 32, and their own elasticity causes them to spring back and lock onto the edge of the other end of the through hole 32, fixing the cover plate 51 to the connecting seat 31. The two hooks 512 ensure a more even tension when fixing the cover plate 51 to the connecting seat 31. The cover plate 51 is inserted into the recess 33, with its outer side fitting against the inner wall of the recess 33, reducing the risk of liquid and dust entering the through hole 32 through the recess 33 and corroding the connecting piece 41. The four protrusions 331 contact the cover plate 51, limiting the depth of insertion. The four protrusions 331 ensure that the four corners of the cover plate 51 are subject to limiting force, resulting in a more even distribution of force.

[0039] The first protrusion 511 slides into the cavity 411 of the snap-fit ​​member 41. The outer side of the first protrusion 511 touches the cavity wall of the snap-fit ​​member 41, making the snap-fit ​​member 41 fit more closely to the inner wall of the through hole 32 under the contact of the first protrusion 511. This prevents the two ends of the snap-fit ​​member 41 from getting close, solving the problem that the lug 42 can easily slide out from the bottom of the groove 33, causing the snap-fit ​​member 41 to detach from the connector 31. The cover plate 51 touches the lug 42, making the cover plate 51 the same as the limiting piece 43, improving the stability of the snap-fit ​​member 41 and the connector 31.

[0040] In this embodiment, the connecting plate 21 preferably has a mounting hole 211. The snap-fit ​​member 41 passes through the mounting hole 211. Due to the compression of the mounting hole 211, the two spring pieces 44 deform, reducing the distance between them. After the two spring pieces 44 pass through the mounting hole 211, the spring pieces 44 rebound due to their own elasticity, causing the other end of the spring pieces 44 to touch the other side of the connecting plate 21 away from the connecting seat 31. The snap-fit ​​method of the two symmetrical spring pieces 44 touching the connecting plate 21 improves the stability of the snap-fit ​​member 41 when it is snapped onto the connecting plate 21. This achieves the connection of the connecting seat 11 and the connecting plate 21 using the connecting seat 31 and the snap-fit ​​member 41, and the snap-fit ​​connection method eliminates the need for auxiliary tools during installation, improving the convenience of installation.

[0041] Example 2, please refer to Figures 6-9 .

[0042] Based on the original embodiment 1, the snap-fit ​​component 41 has a notch 412. In this embodiment, two notches 412 are preferably provided. The notches 412 are close to the bend of the snap-fit ​​component 41, and the two notches 412 are symmetrical to each other. The notches 412 communicate with the cavity 411. The spring piece 44 is placed in the notch 412, and the other end of the spring piece 44 is fixedly connected to the edge of the notch 412. The other end of the spring piece 44 is close to the bend of the snap-fit ​​component 41.

[0043] One end of the spring piece 44 extends into a horn 441, preferably two horns 441 in this embodiment. A first contact piece 442 extends from one side of one end of the spring piece 44, extending into the notch 412, and is located between the two horns 441. A second contact piece 443 extends from one side of one end of the first contact piece 442.

[0044] When the snap-fit ​​41 is inserted into the mounting hole 211 of the connecting plate 21, as the spring piece 44 passes through the mounting hole 211, the first contact piece 442 and the second contact piece 443 are pressed into the notch 412 by the mounting hole 211, reducing the distance between one end of the two spring pieces 44, allowing the spring piece 44 to pass through the mounting hole 211. The prongs 441 on the spring piece 44 abut against the other side of the connecting plate 21 away from the connecting seat 31. By having the prongs 441 on the spring piece 44 abut against the other side of the connecting plate 21 away from the connecting seat 31, and one side of one end of the first contact piece 442 abut against the other side of the connecting plate 21 away from the connecting seat 31, the snap-fit ​​41 is detachably snapped onto the connecting plate 21. The second contact piece 443 abuts against the inner wall of the mounting hole 211. Because the spring piece 44 is tilted at a certain angle on the snap-fit ​​member 41, with one end of the spring piece 44 snapping onto the connecting plate 21, when the snap-fit ​​member 41 is pulled by an external force, the other end of the spring piece 44 is pulled by the snap-fit ​​member 41, causing one end of the spring piece 44 to slip and slide on the connecting plate 21, making the angle between the spring piece 44 and the snap-fit ​​member 41 larger until the spring piece 44 breaks and is damaged. The second contact piece 443 contacts the inner wall of the mounting hole 211, limiting the movement of one end of the spring piece 44 and protecting the spring piece 44 from damage when the snap-fit ​​member 41 is pulled by an external force. When it is necessary to remove the snap-fit ​​member 41, by squeezing the two second contact pieces 443, one end of the two spring pieces 44 is driven closer to each other, so that the two spring pieces 44 can pass through the mounting hole 211, and the snap-fit ​​member 41 can be removed and moved away from the connecting plate 21.

[0045] Example 3, please refer to Figure 1 , Figure 2 and Figure 5 .

[0046] Based on the original embodiment 1 or embodiment 2, the connecting seat 31 extends with a second protrusion 311, and the other end of the through hole 32 passes through the second protrusion 311. The second protrusion 311 is provided with two contact surfaces 313, which are close to the edge of the other end of the through hole 32. The limiting piece 43 abuts against the adjacent contact surfaces 313. A limiting part 312 is provided on the outer side of the second protrusion 311. In this embodiment, two limiting parts 312 are preferably provided. The limiting parts 312 are protruding arc-shaped and are located on both sides of the second protrusion 311. The connecting seat 11 is provided with a sliding groove 111, and a limiting groove 112 is provided in the sliding groove 111. In this embodiment, two limiting grooves 112 are preferably provided. The limiting grooves 112 are inwardly concave arc-shaped.

[0047] The second protrusion 311 slides into the slide groove 111, and the slide groove 111 is opened by two arc-shaped limiting parts 312. The arc-shaped limiting parts 312 can be more easily snapped into the slide groove 111 when the connecting seat 11 is installed. The limiting parts 312 slide in the slide groove 111, so that the limiting parts 312 can be detachably snapped into the adjacent limiting grooves 112. The design of the two limiting parts 312 respectively snapping into the two limiting grooves 112 makes the second protrusion 311 more securely snapped into the slide groove 111. When the connecting seat 11 is removed from the connecting seat 31, the arc-shaped limiting parts 312 can easily slide out from the arc-shaped limiting grooves 112, making installation and removal more convenient.

[0048] This invention provides a combined snap-fit ​​fastener. The connecting base is an external device, and the connecting plate is a car body. The connecting base and the connecting plate are detachably connected, allowing the external device to be fixed on the connecting plate. The snap-fit ​​component is placed in a through hole on the connecting plate. The snap-fit ​​component uses a hook and a limiting piece to hold both ends of the through hole, thus fixing the snap-fit ​​component to the connecting plate. The snap-fit ​​component penetrates the connecting plate, and a spring contact contacts the side of the connecting plate away from the connecting plate. This securely fixes the external device to the car body via the connecting plate and the snap-fit ​​component. The snap-fit ​​method facilitates installation without the need for auxiliary tools. Because this solution uses a snap-fit ​​connection method with a spring contact contacting the connecting plate, it reduces vibration during car operation and lowers the fastening force of the snap-fit.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
