Description

Technical Field

[0001] The invention relates to the technical field of fixing brackets. Background Art

[0002] In recent years, with the popularization of smart devices, various electrical components have been installed on vehicles to improve the user's driving experience. There is also a need to fix components on the glass, such as fixing optical sensor components or other sensor components on the windshield, side window glass, and sunroof glass. Since the glass surface is a smooth surface, various components generally cannot be directly fixed on the glass. Therefore, a bracket that can be fixed on the glass surface by bonding or other means is needed to assist in fixing such components on the glass.

[0003] For example, the patent document with the patent number "CN111867888A" discloses a "bracket for attaching a camera to a windshield of a motor vehicle", which can make the camera easily installed on the bracket and easily removed from the bracket. However, when installing the camera in the public document, it is necessary to put the camera into the corresponding slope position on the bracket, and use force on both sides to push the camera down into the slope structure so that the camera is fixed on the bracket. In other words, after the camera is installed on the bracket, it needs to move along the direction of the slope, which results in the assembly solution requiring the bracket to have a larger installation space.

[0004] For the bracket used to fix the components on the glass surface, the upper part of the bracket is generally close to the roof, which results in a small space for installing the components on the bracket. If the bracket structure in the above-mentioned public document is used for installation, there will be a problem of inconvenient installation. In addition, if a fixed bracket in the above-mentioned public document is used, since the slope structure is small and compact, a large downward pressure is required to snap it into place. If the force is uneven during the installation process, it is easy to be skewed, that is, one side is installed in place, while the other side has not been fully inserted into the slope structure. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a bracket and a windshield for fixing components on a glass surface, which are easy to install and labor-saving and do not require a large installation space.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: a bracket for fixing components on a glass surface, wherein the components are provided with a first fixing portion and a second fixing portion for fixing, and the bracket comprises:

[0007] A bottom plate, one side of which is used to connect with the glass surface;

[0008] A limiting structure, the limiting structure is arranged on a side of the bottom plate away from the glass, the limiting structure comprises a slot, and the slot allows the first fixing part to be inserted into the slot after being rotated by a certain angle;

[0009] A stopper, one end of which is connected to the bottom plate, and the other end of which extends to a side away from the glass and is used to abut against the surface of the component;

[0010] A clamping piece, wherein the clamping piece is arranged on a side of the bottom plate facing away from the glass, and the clamping piece is clamped with the second fixing part. After the clamping piece is clamped with the second fixing part, the direction of at least one component force applied to the second fixing part is opposite to the direction of at least one component force applied by the stopper on the component.

[0011] Furthermore, the limiting structure also includes a limiting seat and a cantilever, one end of the cantilever is fixedly connected to the bottom plate, and the other end is located above the slot, and the slot is formed between the limiting seat and the cantilever.

[0012] Furthermore, the slot includes a pre-locking slot for allowing the first fixing part to enter the cantilever and the limit seat at a fixed angle, and the slot also includes a fixing slot for allowing the first fixing part to rotate a certain angle, the pre-locking slot and the fixing slot are connected to each other, the end of the cantilever located above the slot is a supporting end protruding toward the slot direction, the limit seat includes a pre-locking inclined surface and an arc surface, the pre-locking slot is located between the supporting end and the pre-locking inclined surface, and the fixing slot is located between the supporting end and the arc surface.

[0013] Furthermore, the rotation angle range of the first fixing portion in the slot is ε, 20°≤ε≤80°.

[0014] Furthermore, the stopper is an elastic sheet.

[0015] Furthermore, a reinforcing rib is provided at the connection between the stopper and the bottom plate.

[0016] Furthermore, the clamping part includes a supporting part and a clamping part, the supporting part is connected to the base plate, and the clamping part is arranged at one end of the supporting part away from the base plate. When the component is not connected to the bracket, the angle between the supporting part and the base plate is α, 70°≤α≤100°.

[0017] Furthermore, the clamping member also includes a clamping member root, the support portion is fixedly connected to the base plate via the clamping member root, and the angle between the clamping member root and the base plate is γ, 130°≤γ≤180°.

[0018] Furthermore, the clamping portion includes a contact surface, the contact surface contacts the second fixing portion and applies pressure to the second fixing portion, and the angle between the contact surface and the bottom plate is β, 0°≤β≤50°.

[0019] Furthermore, the clamping portion also includes a first inclined surface and a second inclined surface connected in sequence. During the clamping process of the clamping member and the second fixed portion, the first inclined surface contacts the clamping portion before the second inclined surface. The first inclined surface has an inclination angle δ relative to the second inclined surface, 0°≤δ≤40°.

[0020] The beneficial effects of the bracket for fixing components on the glass surface in the present invention are: the installation space required for the components to be installed on the bracket is small; the components can be fixedly installed by rotating in the card slot, which not only makes the installation steps more convenient and simple, but also makes the components less likely to be skewed during installation, thereby improving installation efficiency.

[0032] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0033] Please refer to Figure 1 and Figure 2 As shown, a bracket 1 for fixing a component 2 on a glass surface of the present invention, the component 2 is provided with a first fixing portion 21 and a second fixing portion 22 for fixing, and the bracket 1 comprises:

[0034] A bottom plate 3, one side of which is used to connect with the glass surface;

[0035] A limiting structure 4, which is disposed on a side of the bottom plate 3 facing away from the glass, and includes a slot 41, and the slot 41 allows the first fixing portion 21 to be inserted into the slot 41 after being rotated by a certain angle;

[0036] A stopper 5, one end of which is connected to the bottom plate 3, and the other end of which extends to a side away from the glass and is used to abut against the surface of the component 2;

[0037] The clamping member 6 is arranged on a side of the bottom plate 3 facing away from the glass, and the clamping member 6 is clamped with the second fixing portion 22. After the clamping member 6 is clamped with the second fixing portion 22, the direction of at least one component force applied to the second fixing portion 22 is opposite to the direction of at least one component force applied by the stop member 5 on the component 2.

[0038] Among them, the component 2 can be specifically a sensor component 2 or other components 2 that need to be installed on the glass surface, such as a camera, a laser radar, an ADAS sensor, a recording device, etc. In addition, the component 2 can also be a rearview mirror, etc. sensor, etc. The first fixing portion 21 on the component 2 is specifically a block-shaped structure protruding outward, and the second fixing portion 22 is specifically a block-shaped structure protruding outward or a groove-shaped structure recessed inward. There are at least two first fixing portions 21 and they are respectively arranged on two opposite sides of the component 2. In some preferred embodiments, there are two first fixing portions 21 and they are symmetrically arranged on both sides of the component 2. There are at least two second fixing portions 22 and they are respectively arranged on two opposite sides of the component 2. In some preferred embodiments, there are two second fixing portions 22 and they are symmetrically arranged on both sides of the component 2.

[0039] The side of the bottom plate 3 connected to the glass surface is preferably fixedly connected to the inner surface of the glass by gluing. In some more preferred embodiments, the bottom plate 3 is bonded to the inner surface of the glass by polyurethane glue.

[0040] Among them, the number and position of the limiting structures 4 and the clamping parts 6 correspond to the first fixing part 21 and the second fixing part 22 on the component 2. In some preferred embodiments, there are two limiting structures 4 and they are symmetrically arranged on the bracket 1, and there are two clamping parts 6 and they are symmetrically arranged on the bracket 1. The limiting structures 4 and the clamping structures jointly fix the component 2 on all sides.

[0041] Among them, the process of installing the component 2 on the bracket 1 is to first extend the first fixing part 21 on the component 2 into the groove of the limiting structure 4, and then rotate it at a certain angle to make the second fixing part 22 close to the clamping part 6, until the first fixing part 21 is rotated into place in the groove and cannot continue to rotate, and the clamping part 6 and the second fixing part 22 are also clamped at the same time. At the same time, the side of the stopper 5 facing away from the glass will also rest against the surface of the component 2. Since the direction of at least one component force applied to the second fixing part 22 after the clamping part 6 is clamped with the second fixing part 22 is opposite to the direction of at least one component force applied to the component 2 by the stopper 5, the clamping part 6 and the stopper 5 will clamp the component 2, thereby achieving the purpose of comprehensively fixing the component 2.

[0042] Please refer to Figure 3 and Figure 4As shown, in some embodiments, the limiting structure 4 further includes a limiting seat 42 and a cantilever 43, one end of the cantilever 43 is fixedly connected to the bottom plate 3, and the other end is located above the slot 41, and the slot 41 is formed between the limiting seat 42 and the cantilever 43. The limiting seat 42 can be a part of the bottom plate 3, or a seat structure protruding from the bottom plate 3, and one end of the cantilever 43 is fixed, and the other end is located above the slot 41 and is a support end 431. When the first fixing portion 21 rotates in the slot 41, the support end 431 of the cantilever 43 serves as a rotation fulcrum of the first fixing portion 21 so that it will not separate from the slot 41, and when the first fixing portion 21 rotates to the right position, the cantilever 43 plays a role in limiting the first fixing portion 21.

[0043] Please refer to Figure 4 As shown, in some embodiments, the slot 41 includes a pre-locking slot 411 for allowing the first fixing portion 21 to enter between the cantilever 43 and the limit seat 42 at a fixed angle, and the slot 41 also includes a fixing slot 412 for allowing the first fixing portion 21 to rotate a certain angle, the pre-locking slot 411 and the fixing slot 412 are connected to each other, and the end of the cantilever 43 located above the slot 41 is a supporting end 431 protruding toward the slot 41, and the limit seat 42 includes a pre-locking inclined surface 421 and an arc surface 422, the pre-locking slot 411 is located between the supporting end 431 and the pre-locking inclined surface 421, and the fixing slot 412 is located between the supporting end 431 and the arc surface 422. Among them, the pre-locking groove 411 and the fixed groove 412 can be independent of each other or partially overlap. The pre-locking groove 411 allows the first fixed part 21 to enter between the cantilever 43 and the limit seat 42 at a fixed angle. The first fixed part 21 cannot rotate when moving in the pre-locking groove 411. This can prevent the first fixed part 21 from deflecting during the installation process and causing the installation to be skewed.

[0044] Please refer to Figure 4 As shown, in some embodiments, the rotation angle range of the first fixing portion 21 in the slot 41 is ε, 20°≤ε≤80°. In some preferred embodiments, the rotation angle range of the first fixing portion 21 in the slot 41 is 30°≤ε≤60°. Further, the rotation angle of the first fixing portion 21 in the slot 41 can be specifically 30°, 40°, 50°, 60°, etc.

[0045] Please refer to Figure 2 and Figure 3As shown, in some embodiments, the stopper 5 is an elastic sheet. In some preferred embodiments, the stopper 5 specifically includes a support table and a root of the stopper 5 integrally arranged with the support table. The support table can be elastically swung relative to the root of the stopper 5, so that when the support table contacts the surface of the component 2, the support table can be elastically deformed to squeeze the component 2, so as to play a role in supporting and fixing the component 2. In addition, in some other embodiments, the stopper 5 is not limited to a sheet, but can also be a block or other special-shaped structure. The stopper 5 needs to ensure that after the component 2 is installed in place, at least one part is in contact with the component 2, and provide the component 2 with a torque opposite to the rotation direction when it is installed, and at the same time cooperate with the clamping member 6 to limit the component 2 so that it maintains a torque balance, thereby improving its stability when subjected to vibration.

[0046] Please refer to Figure 3 As shown, in some embodiments, a reinforcing rib 51 is provided at the connection between the stopper 5 and the bottom plate 3. The reinforcing rib 51 is connected between the root of the stopper 5 and the bottom plate 3 at the same time, and its function is to maintain the shape of the support table and share the pressure exerted by the component 2 on the stopper 5, so as to improve the stability of the component 2 after being fixed and prevent the stopper 5 from being damaged by pressure.

[0047] Please refer to Figures 5 to 7 As shown, in some embodiments, the clamping member 6 includes a supporting portion 61 and a clamping portion 62, the supporting portion 61 is connected to the bottom plate 3, and the clamping portion 62 is arranged at one end of the supporting portion 61 away from the bottom plate 3, as shown in FIG. Figure 6 As shown, when the component 2 is not connected to the bracket 1, the angle between the support portion 61 and the base plate 3 is α, 70°≤α≤100°. In some preferred embodiments, the angle between the support portion 61 and the base plate 3 is 80°≤α≤90°. Further, the angle between the support portion 61 and the base plate 3 can be 80°, 83°, 85°, 87°, 90°, etc. Among them, the support portion 61 and the clip 6 are arranged in an L shape. In the process of clipping the clip 6 with the second fixing portion 22, the component 2 will first squeeze the clip 6 to make the support portion 61 swing. When the clip 6 and the second fixing portion 22 are clipped into place, the support portion 61 will return to its original position, so that the clip 6 and the second fixing portion 22 form a stable connection. Among them, as Figure 7 As shown, the swing angle of the support portion 61 is θ, 5°≤θ≤30°, and further, the swing angle of the support portion 61 is 10°≤θ≤20°.

[0048] Please refer to Figures 5 to 7 As shown, in some embodiments, the clamping member 6 further includes a clamping member root 63, and the support portion 61 is fixedly connected to the bottom plate 3 via the clamping member root 63. Figure 6As shown, the angle between the root 63 of the clip and the bottom plate 3 is γ, 130°≤γ≤180°. In some preferred embodiments, the angle between the root 63 of the clip and the bottom plate 3 is γ, 140°≤γ≤150°. Further, the angle between the root 63 of the clip and the bottom plate 3 can be 140°, 142°, 145°, 148°, 150°, etc., wherein the root 63 of the clip can make the support part 61 have at least two swing axes when swinging, one of which is the connection between the root 63 of the clip and the bottom plate 3, and the other is the connection between the support part 61 and the root 63 of the clip. The two swing axes can be parallel to each other or have an acute angle relationship of less than 90° with each other. The two swing axes can not only change the swing direction of the support part 61, but also make the support part 61 have better toughness to avoid damage to the support part 61 during the swinging process due to extrusion.

[0049] Please refer to Figures 5 to 7 As shown, in some embodiments, the clamping portion 62 includes a contact surface 621, and the contact surface 621 contacts the second fixing portion 22 and applies pressure to the second fixing portion 22, such as Figure 5 As shown, the angle between the contact surface 621 and the bottom plate 3 is β, 0°≤β≤50°. In some preferred embodiments, the angle between the contact surface 621 and the bottom plate 3 is 20°≤β≤40°. Further, the angle between the contact surface 621 and the bottom plate 3 can be 20°, 25°, 30°, 35°, 40°, etc. Among them, since the second fixing portion 22 and the clamping member 6 are clamped during the rotation of the component 2, a certain angle between the contact surface 621 and the bottom plate 3 can make the second fixing portion 22 and the clamping member 6 engage more smoothly.

[0050] Please refer to Figure 6 and Figure 7 As shown, in some embodiments, the clamping portion 62 further includes a first inclined surface 622 and a second inclined surface 623 connected in sequence. During the clamping process of the clamping member 6 and the second fixing portion 22, the first inclined surface 622 contacts the clamping portion 62 before the second inclined surface 623. Figure 7As shown, the first inclined surface 622 has an inclination angle δ relative to the second inclined surface 623, 0°≤δ≤40°. In some preferred embodiments, the inclination angle of the first inclined surface 622 relative to the second inclined surface 623 is 20°≤δ≤30°. Further, the inclination angle of the first inclined surface 622 relative to the second inclined surface 623 can be 20°, 22°, 25°, 28°, 30°, etc. In the process of the clamping portion 62 contacting the second fixing portion 22, the inclination amplitude of the first inclined surface 622 is relatively large. Therefore, when the second fixing portion 22 applies a force to the first inclined surface 622, the first inclined surface 622 will be subjected to an outward horizontal component force, so that the clamping member 6 is squeezed outward as a whole, so as to ensure that the second fixing portion 22 can move forward normally until it is clamped with the clamping portion 62, and the second inclined surface 623 is closer to a vertical state than the first inclined surface 622.

[0051] Another embodiment of the present application is a windshield, comprising a bracket 1 as described above for fixing a component 2 on a glass surface. The windshield may be a front windshield or a rear windshield, and in this embodiment, it is preferably a front windshield. The bracket 1 is fixed to the inner surface of the windshield, and the inner surface is the side of the windshield close to the inside of the vehicle after the windshield is installed on the vehicle body. The component 2 is specifically a camera, and the camera is installed on the top of the windshield through the bracket 1.

[0052] The camera has two symmetrical first fixing parts 21 and two symmetrical second fixing parts 22, both of which are convex sheet structures. When installing the camera, the bracket 1 needs to be fixed on the windshield by bonding first, and then the two first fixing parts 21 on the camera are simultaneously inserted into the pre-locking groove 411 on the bracket 1 at a certain angle relative to the plane of the bracket 1. When the first fixing part 21 moves into the fixing groove 412, the camera is rotated at a certain angle as a whole. At this time, the first fixing part 21 uses the support end 431 as a fulcrum and rotates along the arc surface 422 until the second fixing part 22 is engaged with the engaging part 62 of the engaging member 6. At the same time, the supporting table of the stopper 5 fits with the surface of the camera to improve the stability of the camera after being fixed.

Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
