Description

Technical Field

[0001] This utility model relates to the field of camera technology, and more specifically to a vehicle-mounted camera module bracket. Background Technology

[0002] With the rapid development of automotive intelligence and connectivity technologies, in-vehicle cameras, as key perception components for autonomous driving and assisted driving systems, directly impact the overall vehicle safety performance through their installation reliability and environmental adaptability. Currently, in-vehicle camera modules are typically connected and fixed to the vehicle body via brackets. However, in practical applications, this traditional assembly method has many shortcomings.

[0003] Regarding assembly and connection, some existing technologies use a single clip or bolt fixing method. Clip fixing is prone to loosening due to vibration during vehicle movement, causing the camera module to shift position and affecting the accuracy of the captured images. On the other hand, relying solely on bolt connections is not only inefficient in installation, but also prone to stress concentration at the bolt connection points when the vehicle is subjected to impact, reducing the connection strength between the bracket and the vehicle body. In addition, existing assembly processes make it difficult to achieve rapid pre-positioning of the bracket and the vehicle body, increasing assembly time and labor costs.

[0004] In terms of sealing and protection, when the vehicle is in motion, rainwater and dust from the outside can easily seep into the vehicle's cabin through the gaps in the joints, causing malfunctions such as water accumulation inside the vehicle and short circuits, which seriously affect the vehicle's service life and operational stability. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to improve the installation efficiency of vehicle camera module bracket.

[0006] This utility model solves the above-mentioned technical problems through the following technical means: a vehicle camera module bracket, including a module bracket, which is connected to a counter part on the vehicle body by bolts and buckles, and the buckles can position the module bracket in at least one direction around the counter part.

[0007] As a preferred technical solution, the hand component includes a body sheet metal, on which mounting holes adapted to the clips and bolt holes adapted to the bolts are provided.

[0008] As a preferred technical solution, the buckle includes a fixing buckle, and the bottom of the end of the fixing buckle facing the opponent has an arc-shaped surface.

[0009] As a preferred technical solution, the buckle includes a first elastic buckle and / or a second elastic buckle, and the first elastic buckle and the second elastic buckle are detachably fixed to the counters.

[0010] As a preferred technical solution, the end of the module bracket facing the vehicle body is also provided with foam. The circumferential dimension of the foam is the same as that of the module bracket, and its central through hole is adapted to the size of the mounting hole on the accessory.

[0011] As a preferred technical solution, the module bracket is fixedly connected with embedded nuts that are compatible with bolts, and the module bracket is also provided with a limiting platform that is compatible with the hand parts.

[0012] As a preferred technical solution, the module bracket has a boss at the end opposite to the opponent component, and the camera module is detachably fixed at the end of the boss opposite to the vehicle body.

[0013] As a preferred technical solution, a waterproof gasket is provided between the connection surface of the boss and the camera module.

[0014] As a preferred technical solution, the boss and the camera module are fastened together by screws.

[0015] As a preferred technical solution, at least one pair of limiting bosses are provided on the end of the boss facing the camera module.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) In this utility model, the module bracket can be quickly positioned with the vehicle body by means of the buckle, avoiding the time spent on repeated hole alignment and alignment in the traditional assembly process, greatly shortening the installation time of a single module bracket, improving the working rhythm of the vehicle assembly line, and thus improving the overall efficiency of automobile production; the buckle can also restrict at least one of the four degrees of freedom of the module bracket, not only realizing pre-clamping fixation, but also providing support for the alignment and installation of the module bracket and the body sheet metal. The fixation is achieved by combining bolts and buckles, which not only avoids stress concentration at the connection point when the vehicle is subjected to external impact, which can lead to damage to the connection part, but also reduces the installation difficulty and the requirements for the operator's skill level.

[0018] (2) In this utility model, by setting foam between the module bracket and the body sheet metal and setting waterproof rubber pads between the module bracket and the camera module, rainwater can be effectively blocked from entering through the gap between the module bracket and the body sheet metal and the gap between the module bracket and the camera module when driving in the rain or when the vehicle passes through muddy sections.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See Figure 1 A vehicle-mounted camera module bracket is connected to a matching component on the vehicle body. In this embodiment, the matching component is a portion of the vehicle body sheet metal 2. The vehicle-mounted camera module bracket includes a module bracket 5, which is connected to the vehicle body sheet metal 2 via clips and bolts. The vehicle body sheet metal 2 can be a planar structure or a non-planar structure. Compared with the prior art, which only uses bolts for connection, the clips can quickly position the module bracket 5 to the vehicle body sheet metal 2, avoiding the time spent on repeated hole alignment and adjustment in the traditional assembly process. This significantly shortens the installation time of a single module bracket 5, improves the working rhythm of the vehicle assembly line, and thus improves the overall efficiency of automobile production. The clips can also restrict at least one of the four degrees of freedom of the module bracket 5, which not only achieves pre-clamping fixation but also provides support for the alignment and installation of the module bracket 5 and the vehicle body sheet metal 2.

[0028] In this embodiment, only one bolt connection structure is used to connect the module bracket 5 and the body sheet metal 2 using a smaller number of bolt connections. This reduces labor costs and avoids stress concentration at the connection point when the vehicle is subjected to external impact, which could lead to damage to the connection. Combined with snap-fit ​​positioning, compared to the existing technology that uses multiple bolts for assembly, the snap-fit ​​and bolt fixing reduces the skill requirements for workers. It should be noted that "a smaller number" in this embodiment refers to no more than two (inclusive) bolt connection structures. Furthermore, the increased assembly efficiency means that more vehicles can be assembled within the same production time, further distributing production costs.

[0029] See Figure 2 The buckles include elastic buckle 1 (9), elastic buckle 2 (10), and fixed buckle 14. The bolt connection structure includes fastening bolt 1 and nut. The bolt connection structure, fixed buckle 14, elastic buckle 1 (9), and elastic buckle 2 (10) are respectively set at the upper, lower, left, and right parts of the module bracket 5. Here, the upper and lower parts refer to the parts above and below the center line in the height direction of the module bracket 5, and the left and right parts refer to the parts to the left and right of the center line in the width direction of the module bracket 5. Of course, the bolt connection structure can also be adjusted according to the different positions of elastic buckle 1 (9), elastic buckle 2 (10), and fixed buckle 14, such as being set at the lower, left, or right parts.

[0030] In this embodiment, elastic buckle 1 9, elastic buckle 2 10, and fixed buckle 14 are all fixedly connected to the module bracket 5 and are located at the end of the module bracket 5 facing the body sheet metal 2. In order to improve the connection effect between the module bracket 5 and the body sheet metal 2, elastic buckle 1 9, elastic buckle 2 10, and fixed buckle 14 are provided simultaneously in this embodiment. Of course, only elastic buckle 1 9, elastic buckle 2 10, fixed buckle 14, elastic buckle 1 9 and fixed buckle 14, elastic buckle 2 10 and fixed buckle 14, or elastic buckle 1 9 and elastic buckle 2 10 can be provided.

[0031] The left and right sides of the module bracket 5 are respectively fixedly connected to U-shaped limiting platform 11 and limiting platform 22. The limiting platform 11 and limiting platform 22 are symmetrically arranged about the center line in the height direction of the module bracket 5. The top plane of the limiting platform 11 and limiting platform 22 is located below the bottom plane of the elastic buckle 19 and elastic buckle 20. The limiting platform 11 and limiting platform 22 are used for auxiliary positioning.

[0032] See Figure 6The body sheet metal 2 has mounting holes 16 that are compatible with elastic buckle 1 9, elastic buckle 2 10 and fixed buckle 14. The fixed buckle 14 is engaged with the lower edge of the mounting hole 16. The elastic buckle 1 9 and elastic buckle 2 10 can pass through the mounting hole 16 and engage with the left and right edges of the mounting hole 16 due to their elasticity.

[0033] To facilitate the locking and positioning of the fixing buckle 14 with the lower edge of the mounting hole 16, the fixing buckle 14 has a concave arc-shaped surface at one end facing the mounting hole 16. The fixing buckle 14 is inserted into the mounting hole 16 at an angle and aligns with the lower edge of the mounting hole 16. This forms the positioning point at the bottom of the module bracket 5. Then, the module bracket 5 is flipped towards the body sheet metal 2. The arc-shaped surface is used to achieve a smooth transition between the module bracket 5 and the body sheet metal 2 during the flipping process.

[0034] The body sheet metal 2 is provided with bolt holes that are compatible with the fastening bolt 1. Similarly, the module bracket 5 is also provided with bolt holes that are compatible with the fastening bolt 1. The end of the fastening bolt 1 that passes through the bolt holes on the body sheet metal 2 and the module bracket 5 is fastened by a nut. In order to improve assembly efficiency, in this embodiment, an embedded nut 13 is fixedly connected to the end of the module bracket 5 away from the body sheet metal 2. The embedded nut 13 corresponds to the position of the bolt hole on the module bracket 5.

[0035] A foam 3 is also provided between the body sheet metal 2 and the module bracket 5. The size of the foam 3 is at least enough to cover the mounting hole 16 to seal the gap between the body sheet metal 2 and the module bracket 5, thereby improving the sealing effect between the body sheet metal 2 and the module bracket 5. A through hole of the same size as the mounting hole 16 is opened in the center of the foam 3 so that the elastic buckle 1 9, elastic buckle 2 10 and fixing buckle 14 of the module bracket 5 can be inserted and connected to the body sheet metal 2. For easy assembly, before the body sheet metal 2 and the module bracket 5 are installed, the adhesive side of the foam 3 is bonded and fixed to the end of the module bracket 5 connected to the body sheet metal 2. After the body sheet metal 2 and the module bracket 5 are installed, rainwater can be effectively prevented from entering through the gap between the module bracket 5 and the body sheet metal 2 when driving in rainy weather or when the vehicle passes through muddy sections.

[0036] See Figure 2 , Figure 4A hollow boss with an incline is fixedly connected to one end of the module bracket 5 away from the body sheet metal 2. This hollow boss is used to install the camera module 7. The hollow boss is detachably fixed to the camera module 7 by screws 4 or bolts. In this embodiment, the connection with screws 4 is taken as an example. Screw holes adapted to screws 4 are opened on both the hollow boss and the camera module 7. Of course, other detachable connection structures in the prior art can also be used. In order to improve the sealing of the connection between the module bracket 5 and the camera module 7, a waterproof gasket 6 is also provided between the hollow boss and the camera module 7. When assembling the hollow boss of the module bracket 5 and the camera module 7, the waterproof gasket 6 is placed between the connection surface of the hollow boss and the camera module 7. The screws 4 are passed through the hollow boss of the module bracket 5, the waterproof gasket 6, and the camera module 7 in sequence to fix the hollow boss of the module bracket 5, the waterproof gasket 6, and the camera module 7. The hollow boss can be inclined or non-inclined. In this embodiment, it is inclined downward as an example.

[0037] See Figure 3 Two limiting protrusions 15 are fixedly connected to the end of the hollow protrusion facing the camera module 7. The limiting protrusions 15 are used to control the compression of the waterproof gasket 6. The compression of the gasket is controlled by preset height of the limiting protrusions 15. For example, if the protrusion height is 1mm and the waterproof gasket thickness is 1.3mm, the compression is 0.3mm. The specific compression is adjusted according to the design of the product. In this embodiment, the two limiting protrusions 15 are respectively set at a diagonal on the end face of the hollow protrusion facing the camera module 7. The end of the camera module 7 away from the hollow protrusion is detachably connected to a camera decorative cover 8, which protects the camera module 7.
