In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0044] Such as Figures 1 to 2As shown, the Z direction shown in the figure is a schematic illustration of the first direction. An embodiment of the first aspect of the present utility model provides a fixing device, which includes a buckle assembly 1 and a socket assembly 2. The buckle assembly 1 includes a first clamping arm 11, a second clamping arm 12, a first pair of claws 13 and a second pair of claws 14. The first clamping arm 11 and the second clamping arm 12 are connected. The first pair of claws 13 are arranged on the first clamping arm 11 and the second clamping arm 12. The second pair of claws 14 are arranged on the first clamping arm 11 and the second clamping arm 12. Both the first pair of claws 13 and the second pair of claws 14 are combined claws each including at least two clamping claws. The first clamping arm 11 and the second clamping arm 12 can respectively support both sides of the first pair of claws 13 and the second pair of claws 14, and can also limit the position and provide protection at the connection position when the first pair of claws 13 and the second pair of claws 14 are connected to the socket assembly 2.

[0045] The socket assembly 2 includes a socket body 21. A first groove 22 is provided on the socket body 21. The first groove 22 extends from the bottom of the socket body 21 towards the top of the socket body 21 along the first direction. The first groove 22 communicates with the bottom of the socket body 21 and penetrates through both side walls of the socket body 21. The first clamping arm 11 and the second clamping arm 12 are sleeved on the socket body 21 along the first direction. The first pair of claws 13 can abut against both sides of the socket body 21 to facilitate limiting the vertical direction perpendicular to the first direction of the buckle assembly 1 and the socket assembly 2. The second pair of claws 14 can be clamped with the first groove 22 to prevent the buckle assembly 1 from detaching from the socket assembly 2 and limit the connection position of the buckle assembly 1 and the socket assembly 2 in the first direction.

[0046] With such a setting, by providing the first groove 22 on the socket body 21, it is not only convenient for the second pair of claws 14 to be clamped and limit the connection position of the buckle assembly 1 and the socket assembly 2 in the first direction, but also the first groove 22 penetrates through the bottom of the socket body 21 and extends from the bottom of the socket body 21 towards the top of the socket body 21, which can make the demolding direction of the socket body 21 consistent with the main demolding direction of the socket assembly 2, eliminating the need for split core pulling for molding, thereby reducing the situation of insufficient demolding stroke, facilitating the simplified design of the mold, reducing costs, improving the yield rate, and solving the problem in the related art that the structure of the buckle and the buckle base is complex and requires multi-directional split core pulling for demolding using sliders, which is prone to the situation of insufficient demolding stroke.

[0047] In this embodiment, the ends of the first clamping arm 11 and the second clamping arm 12 can be directly connected or can be provided with an arc section for transitional connection. The first clamping arm 11 and the second clamping arm 12 can be made of an elastic material to facilitate a certain elastic deformation inwards or outwards, which is convenient for connection and use, reduces damage, and can be connected to external components to be connected such as body plastic parts.

[0048] Such as Figures 1 to 3As shown, in some embodiments, the size of the first groove 22 gradually decreases from the bottom to the top of the seat body 21, so that the groove wall of the first groove 22 forms a certain draft angle, which facilitates the extraction of the core during demolding and improves the yield rate.

[0049] As Figures 1 to 3 shown, in some embodiments, the card holder assembly 2 includes two first protrusions 23, which are arranged on the seat body 21 and on both sides of the seat body 21, so as to facilitate the blocking and limiting of the buckle assembly 1 by the first protrusions 23 on both sides of the seat body 21. The two first protrusions 23 are located on both sides of the first groove 22, the thickness of the first protrusion 23 is greater than the thickness of the seat body 21, the first clamping arm 11 and the second clamping arm 12 can extend between the two first protrusions 23, and the two first protrusions 23 can be respectively arranged on both sides of the first clamping arm 11 and the second clamping arm 12 to limit the first clamping arm 11 and the second clamping arm 12, avoiding the movement of the buckle assembly 1 and the card holder assembly 2 in the vertical direction perpendicular to the first direction, and improving the connection stability between the buckle assembly 1 and the card holder assembly 2.

[0050] In this embodiment, the first protrusion 23 can be a strip-shaped structure. The first protrusions 23 are arranged on the two side walls of the first groove 22 and on the top wall of the seat body 21. The size of the first protrusion 23 gradually decreases from the bottom to the top of the seat body 21, and the size of the seat body 21 can also gradually decrease from its own bottom to its own top, so as to facilitate the formation of a draft angle, facilitate demolding, and improve the yield rate.

[0051] As Figures 1 to 3 shown, in some embodiments, the card holder assembly 2 further includes a second protrusion 24, which is arranged on the first protrusion 23 and extends vertically along the first direction. The second protrusion 24 is arranged at the bottom position of the first protrusion 23. The second protrusion 24 can be connected to an external component to be connected, which facilitates the limiting between the external component to be connected and the card holder assembly 2 during connection, reduces movement, and improves connection stability.

[0052] In this embodiment, the second protrusion 24 can be a block structure. The protruding direction of the second protrusion 24 is the same as that of the first protrusion 23, and the widths of the first protrusion 23 and the second protrusion 24 can also be the same, so as to facilitate demolding.

[0053] As Figures 1 to 3As shown, in some embodiments, the card seat assembly 2 further includes a third protruding portion 25. The third protruding portion 25 is disposed on the seat body 21, and the third protruding portion 25 is located at the side of the first protruding portion 23. The protruding direction of the third protruding portion 25 intersects with the protruding direction of the first protruding portion 23, that is, the protruding directions of the third protruding portion 25 and the first protruding portion 23 are in different directions and have an included angle. For example, the third protruding portion 25 and the first protruding portion 23 are respectively disposed on adjacent side walls of the seat body 21, and the protruding direction of the third protruding portion 25 is perpendicular to the protruding direction of the first protruding portion 23. With such a setting, the third protruding portion 25 can cooperate with the second protruding portion 24 and the first protruding portion 23 to limit the connection between the card seat assembly 2 and an external connection member to be connected in different vertical directions in the first direction, reducing movement.

[0054] In this embodiment, the third protruding portion 25 can be of a long strip structure, and the dimension of the third protruding portion 25 from the bottom of the seat body 21 to the top of the seat body 21 can also gradually decrease, facilitating the formation of a draft angle and demolding. Among them, the third protruding portion 25 can extend from the bottom of the seat body 21 to the top of the seat body 21, and the end of the third protruding portion 25 close to the top of the seat body 21 can be designed as a tip, that is, the top of the third protruding portion 25 can be a slope, facilitating demolding.

[0055] As Figures 1 to 3 shown, in some embodiments, the top of the first protruding portion 23 is an arc surface, which can reduce the setting of sharp corners and facilitate demolding. The top of the seat body 21 is an arc surface, which not only facilitates demolding but also facilitates the extrusion of the first pair of claws 13 and the second pair of claws 14, making the connection process smoother.

[0056] As Figures 1 to 2 and Figure 4 shown, in some embodiments, a second groove 15 is provided on the first clamping arm 11. The second groove 15 penetrates the inner and outer sides of the first clamping arm 11. A third groove 16 is provided on the second clamping arm 12. The third groove 16 penetrates the inner and outer sides of the second clamping arm 12. The second groove 15 and the third groove 16 can provide installation and displacement spaces for the first pair of claws 13 and the second pair of claws 14, reducing the occupation of the internal space between the first clamping arm 11 and the second clamping arm 12 by the first pair of claws 13 and the second pair of claws 14.

[0057] As Figures 1 to 2 and Figure 4As shown, in some embodiments, fourth protrusions 17 are provided at the bottoms of the first clamping arm 11 and the second clamping arm 12. The fourth protrusions 17 extend vertically in a direction perpendicular to the first direction. The fourth protrusions 17 are used for clamping connection with an external component to be connected. Fifth protrusions 18 are provided on the sides of the first clamping arm 11 and the second clamping arm 12. The fifth protrusions 18 extend vertically in a direction perpendicular to the first direction. The fifth protrusions 18 are used for clamping connection with an external component to be connected. That is, after the buckle assembly 1 and the clamping seat assembly 2 are connected to form a fixing device, the entire fixing device can be connected to an external component to be connected. The fourth protrusions 17 and the fifth protrusions 18 on the first clamping arm 11 and the second clamping arm 12 can both be connected to the external component to be connected, forming a multi-point connection, reducing the detachment of the buckle assembly 1 from the external component to be connected, and improving the connection stability.

[0058] In this embodiment, the fourth protrusion can be a long strip-shaped structure extending in the width direction of the first clamping arm 11 and the second clamping arm 12, with a large connection distance.

[0059] As Figures 1 to 2 and Figure 4 As shown, in some embodiments, the first pair of claws 13 includes a first claw 131 and a second claw 132. The first claw 131 is provided on the first clamping arm 11. One end of the first claw 131 is connected to the wall of the second groove 15. The other end of the first claw 131 is provided with a first abutting portion 133. The first abutting portion 133 can abut against the seat body 21. The first claw 131 can undergo elastic deformation under the extrusion of the seat body 21. The second claw 132 is provided on the second clamping arm 12. The first claw 131 and the second claw 132 are arranged opposite to each other. One end of the second claw 132 is connected to the wall of the third groove 16. The other end of the second claw 132 is provided with a second abutting portion 134. The second claw 132 can undergo elastic deformation under the extrusion of the seat body 21.

[0060] In this setting, the first pair of claws 13 can be arranged above the second pair of claws 14. When the first pair of claws 13 are not connected, the first claw 131 and the second claw 132 can extend into the cavity between the first clamping arm 11 and the second clamping arm 12, and the distance between the first claw 131 and the second claw 132 is less than the thickness of the seat body 21. When the seat body 21 extends between the first pair of claws 13, the seat body 21 can squeeze the first claw 131 and the second claw 132. The first claw 131 can use the first clamping arm 11 as a support, and the second claw 132 can use the second clamping arm 12 as a support. The first claw 131 and the second claw 132 can abut and fix both sides of the seat body 21 through the first abutting portion 133 and the second abutting portion 134, improving the connection stability between the buckle assembly 1 and the card seat assembly 2. Moreover, the second groove 15 and the third groove 16 can provide a connection and swing deformation space for the first claw 131 and the second claw 132, reducing the requirements for the chamber space between the first clamping arm 11 and the second clamping arm 12 and the thickness of the two clamping arms, which is convenient for processing.

[0061] Wherein, the surfaces of the first abutting portion 133 and the second abutting portion 134 are arc surfaces, which are convenient for the end of the seat body 21 to enter. Moreover, the arc surfaces of the first abutting portion 133 and the second abutting portion 134 cooperate with the arc surface at the top of the seat body 21, which can reduce extrusion damage and ensure smooth insertion connection.

[0062] In this embodiment, the first claw 131 and the second claw 132 can be made of an elastic material, or the first claw 131 and the second claw 132 can also be made of a rigid material with a smaller thickness at the connection positions with the corresponding first clamping arm 11 and second clamping arm 12, as long as the first claw 131 and the second claw 132 can undergo elastic deformation.

[0063] As Figures 1 to 2 and Figure 4 shown, in some embodiments, the second pair of claws 14 includes a third claw 141 and a fourth claw 142. The third claw 141 is arranged on the first clamping arm 11. One end of the third claw 141 is connected to the groove wall of the second groove 15, and a first clamping portion 143 is arranged at the other end of the third claw 141. The first clamping portion 143 can be clamped with the first groove 22, and the third claw 141 can undergo elastic deformation under the extrusion of the seat body 21. The fourth claw 142 is arranged on the second clamping arm 12. The third claw 141 and the fourth claw 142 are arranged oppositely. One end of the fourth claw 142 is connected to the groove wall of the third groove 16, and a second clamping portion 144 is arranged at the other end of the fourth claw 142. The second clamping portion 144 can be clamped with the first groove 22, and the fourth claw 142 can undergo elastic deformation under the extrusion of the seat body 21.

[0064] With such a setting, when the second pair of claws 14 are not connected, the distance between the third claw 141 and the fourth claw 142 can be smaller than the thickness of the seat body 21. When the seat body 21 extends into the space between the second pair of claws 14, the seat body 21 can squeeze the third claw 141 and the fourth claw 142. The third claw 141 can rely on the first clamping arm 11 as a support, and the fourth claw 142 can rely on the second clamping arm 12 as a support. The third claw 141 and the fourth claw 142 can be clamped with the first groove 22 on the seat body 21 through the first clamping portion 143 and the second clamping portion 144, so that the third claw 141 and the fourth claw 142 can be abutted and clamped on both sides and below the seat body 21, and can cooperate with the first claw 131 and the second claw 132 to perform multi-angle limiting, reducing the disengagement of the buckle assembly 1 from the card seat assembly 2.

[0065] Wherein, the first clamping portion 143 and the second clamping portion 144 are clamping rods or open slots. The clamping rods extend along the vertical direction of the first direction and are arranged towards the seat body 21. The clamping rods can extend into the first groove 22 and abut against the groove wall of the first groove 22. The clamping rods can be clamped with the first groove 22 to reduce the seat body 21 from disengaging from the third claw 141 and the fourth claw 142, and the clamping is flexible and convenient. After the clamping rods extend into the first groove 22, the ends of the third claw 141 and the fourth claw 142 can abut against both sides of the seat body 21, improving the connection stability.

[0066] The open slot can allow a part of the seat body 21 to enter. The groove wall of the open slot can abut against the groove wall of the first groove 22. The third claw 141 and the fourth claw 142 are blocked on both sides of the seat body 21. The open slot can be directly opened at the ends of the third claw 141 and the fourth claw 142. The bottom wall of the open slot can abut against the groove wall of the first groove 22, and the side wall of the open slot can abut against the side wall of the seat body 21. The connection area is large and the connection is stable.

[0067] As Figure 5 shown, an embodiment of the second aspect of the present invention provides a vehicle, including a first component to be connected, a second component to be connected, and the fixing device in any of the above solutions. One of the first component to be connected and the second component to be connected is connected to the buckle assembly 1, and the other is connected to the card seat assembly 2. The first component to be connected and the second component to be connected are both components to be connected. The first component to be connected and the second component to be connected can be, but are not limited to, interior and exterior decorative panels and body panels.

[0068] In use, the card seat assembly 2 can be connected to the first component to be connected, and then the buckle assembly 1 is connected to the card seat assembly 2 to form a combined buckle structure. The second component to be connected has a card slot corresponding to the combined buckle structure. The second component to be connected can be connected to the first clamping arm 11 and the second clamping arm 12 of the buckle assembly 1 and the seat body 21 of the card seat assembly 2, with firm connection. By providing a first groove 22 in the seat body 21, it is not only convenient for the second pair of claws 14 to be clamped, and limits the connection position of the buckle assembly 1 and the card seat assembly 2 in the first direction, but also the first groove 22 penetrates the bottom of the seat body 21 and extends from the bottom of the seat body 21 towards the top of the seat body 21, enabling the demolding direction of the seat body 21 to be consistent with the main demolding direction of the card seat assembly 2, eliminating the need for parting core-pulling molding, thereby reducing the situation of insufficient demolding stroke, facilitating the streamlined design of the mold, reducing costs, and improving the yield rate.
