[0028] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0029] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0030] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0032] Considering that in order to ensure that the laser radar can operate stably and reliably in a low-temperature environment in the related art, the laser radar and the heating film are generally installed on the mounting bracket at the same time to achieve effective heating of the laser radar and ensure its performance in a low-temperature environment. However, the mounting bracket in the related art often only considers the separate installation of the laser radar or the heating film, and does not optimize the design from the overall perspective, which is not conducive to the layout and design of the vehicle. The present application provides a mounting bracket and a laser radar device, which can optimize the layout between the laser radar and the heating film from the overall perspective, reduce the overall volume occupied in the vehicle space, and improve the compactness of the structural arrangement, which is conducive to the layout and design of the vehicle.

[0033] Please refer to the attached Figure 1 and Figure 2 An embodiment of the present application provides a laser radar device 10, which may include a laser radar 11, a heating film 12, and a mounting bracket 13. Specifically, the present application makes the following improvements to the mounting bracket 13.

[0034] Please continue reading Figure 1 An embodiment of the present application provides a mounting bracket 13, which may include a first bracket 100 and a second bracket 200. Figure 2As shown, the first bracket 100 is provided with a first mounting portion 110 for mounting the heating film 12. The second bracket 200 is provided with a second mounting portion 210 for mounting the laser radar 11. The second bracket 200 is detachably connected to the first bracket 100 in a direction facing the first mounting portion 110. The first mounting portion 110 and the second mounting portion 210 are spaced apart along the width direction X of the first bracket 100, so that the heating film 12 and the laser radar 11 can be arranged to avoid each other along the width direction X of the first bracket 100.

[0035] It should be noted that the above-mentioned laser radar device 10 provided in the present application has a heating film 12 that can be adaptively installed on the first mounting portion 110, and the laser radar 11 is installed on the side of the second mounting portion 210 facing the first bracket 100, and the heating film 12 and the laser radar 11 are arranged to avoid each other along the width direction X of the first bracket 100.

[0036] The above-mentioned mounting bracket 13 and laser radar device 10 are designed to be arranged at intervals along the width direction X of the first bracket 100 by the first mounting portion 110 and the second mounting portion 210. This allows the heating film 12 and the laser radar 11 to be arranged to avoid each other along the width direction X of the first bracket 100. This helps to reduce the volume of the laser radar 11 and the heating film 12 in the height direction where the first bracket 100 and the second bracket 200 are connected to each other, which is beneficial to the spatial layout of the vehicle.

[0037] Please continue reading Figure 3 Optionally, the first mounting portion 110 may be provided with an avoidance hole 1112a. The avoidance hole 1112a is used to be arranged opposite to the lens of the laser radar 11, or the lens of the laser radar 11 is used to pass through the avoidance hole 1112a and be arranged on the side of the first mounting portion 110 away from the heating film 12.

[0038] Specifically, the first mounting portion 110 is provided with an avoidance hole 1112a, so that the lens of the laser radar 11 can be arranged opposite to the avoidance hole 1112a, and then the signal that the laser radar 11 needs to receive, such as the light signal, can be input into the lens of the laser radar 11 through the above-mentioned avoidance hole 1112a, thereby ensuring the working effect of the laser radar 11.

[0039] In addition, the setting of the avoidance hole 1112a also helps to enable the lens of the laser radar 11 to pass through the avoidance hole 1112a and be arranged on the side of the first mounting part 110 away from the heating film 12. This can further optimize the layout of the laser radar 11 and the heating film 12, reduce the overall occupied area of ​​the laser radar 11 and the first mounting part 110 in the width direction X, improve the compactness of the structural arrangement, and enable the lens of the laser radar 11 to be arranged close to the heating film 12 to receive effective heating, thereby ensuring the performance of the laser radar 11 in low temperature environments.

[0040] Optionally, the first bracket 100 and the second bracket 200 may be connected by, but not limited to, snapping, bonding, or welding, which is not limited here.

[0041] See also Figure 1 and Figure 2 In some embodiments, the first bracket 100 and the second bracket 200 may be provided with corresponding holes 100b and are locked together by a locking member 600. Specifically, the locking member 600 and the hole 100b may be, but are not limited to, implemented as a bolt member and a bolt hole.

[0042] Optionally, see Figure 2 The first mounting portion 110 may include a mounting boss 111, the mounting boss 111 having a first mounting surface 1111 and a mounting side surface 1112 connected to each other, and the first mounting surface 1111 is arranged facing the second bracket 200. Figure 3 As shown, the first mounting surface 1111 is used to mount the heating film 12, and the avoidance hole 1112a passes through the mounting side surface 1112. Figure 4 As shown, the first mounting surface 1111 has a cavity 100a on the side facing away from the heating film 12, and the avoidance hole 1112a is connected to the cavity 100a, so that the lens of the laser radar 11 can pass through the avoidance hole 1112a to the cavity 100a. In this way, the heating film 12 can heat the cavity 100a to ensure the uniformity of heating of the lens of the laser radar 11 in the cavity 100a, thereby ensuring the performance of the laser radar 11 in a low temperature environment.

[0043] Understandably, in this embodiment, the laser radar 11 can be installed on the side directly opposite the mounting side 1112. This ensures that the lens of the laser radar 11 is directly opposite and penetrates the avoidance hole 1112a, thereby improving the compatibility of the laser radar 11 with the first mounting portion 110. The heating film 12 can be directly attached to the first mounting surface 1111. In this way, the heating film 12 can heat the first mounting surface 1111 and then transfer the heat to the above-mentioned cavity 100a to heat the laser radar 11.

[0044] Optionally, see Figure 2 The second mounting portion 210 may include a mounting groove 211. The mounting groove 211 may be recessed in a direction away from the first bracket 100. The laser radar 11 is mounted in the mounting groove 211. The mounting groove 211 provides sufficient mounting space for the laser radar 11, thereby avoiding the problem of structural interference. Figure 2 From the perspective shown, the mounting groove 211 is provided on a side of the second mounting portion 210 facing the first bracket 100 and is recessed in a direction away from the first bracket 100 .

[0045] Optionally, see Figure 2 The first bracket 100 may include a bottom surface 120, the first mounting surface 1111 is arranged at a first preset angle with the bottom surface 120, and the mounting groove 211 includes a second mounting surface.

[0046] It should be noted that if Figure 2 As shown, the second mounting portion 210 may include an exposed surface 2113, and the second mounting surface of the above-mentioned mounting groove 211 is a side surface on the second mounting portion 210 that is opposite to the exposed surface 2113. It can also be understood that the side surface is arranged on the side of the second mounting portion 210 facing the first bracket 100, and the second mounting surface is used to abut and install the laser radar 11. The second mounting surface is arranged at a second preset angle with the bottom surface 120, and the first preset angle and the second preset angle are offset in the same direction relative to the bottom surface 120. In this way, the laser radar 11 can maintain the same inclination direction as the first mounting surface 1111 after installation, and then can ensure that the laser radar 11 can smoothly pass its lens through the avoidance hole 1112a of the first mounting portion 110 and pass into the cavity 100a after being installed on the mounting groove 211. This can improve the compactness of the structural arrangement while avoiding structural interference problems and facilitate the installation and adaptation of the laser radar 11.

[0047] Optionally, combine Figure 2 and Figure 3 As shown, a limiting structure can be provided on the first mounting surface 1111, and the limiting structure is used to limit and fix the heating film 12. This helps to improve the installation stability of the heating film 12 on the first mounting surface 1111, reduce the problem of weakening of the heating effect caused by the displacement of the heating film 12, or reduce the problem of heating failure caused by the falling off of the heating film 12.

[0048] Specifically, if Figure 3 As shown, the heating film 12 includes an upper edge 121 , a lower edge 122 , a first convex portion 123 and a second convex portion 124 , wherein the first convex portion 123 and the second convex portion 124 are connected to the lower edge 122 and are spaced apart along the length direction of the lower edge 122 .

[0049] Alternatively, as Figure 2 and Figure 3 As shown, the limiting structure may include a first limiting component 410, a second limiting component 420, and a third limiting component 430. The first limiting component 410 is used to limit the upper edge 121, the second limiting component 420 is used to limit the first protrusion 123, and the third limiting component 430 is used to limit the second protrusion 124. This helps to effectively limit and fix the heating film 12 in all directions along the plane of the first mounting surface 1111.

[0050] Specifically, the first limiting assembly 410 may include two spaced-apart limiting protrusions that can limit the position of the heating film 12 in a direction perpendicular to the upper edge 121 and in the plane of the first mounting surface 1111. The second limiting assembly 420 may include two spaced-apart limiting protrusions that can be respectively engaged on both sides of the first protrusion 123 to limit the position of the heating film 12 in the longitudinal direction of the lower edge 122. Preferably, one of the limiting protrusions of the second limiting assembly 420 can also simultaneously abut against the lower edge 122 of the heating film 12, so that the limiting protrusion can cooperate with the first limiting assembly 410 to limit the position of the heating film 12 in a direction perpendicular to the upper edge 121.

[0051] Optionally, the third limiting assembly 430 may include two spaced-apart limiting protrusions that can be respectively engaged with the two sides of the second protrusion 124 to limit the position of the heating film 12 in the longitudinal direction of the lower edge 122. Preferably, one of the limiting protrusions of the third limiting assembly 430 can also simultaneously abut against the lower edge 122 of the heating film 12, so that the limiting protrusion can cooperate with the first limiting assembly 410 to limit the position of the heating film 12 in a direction perpendicular to the upper edge 121.

[0052] Therefore, according to the above-mentioned embodiments of the present application, by setting the first limiting component 410, the second limiting component 420 and the third limiting component 430, the heating film 12 can be limited and fixed in the directions parallel to the upper edge 121 and perpendicular to the upper edge 121. In other words, through the above-mentioned settings, the heating film 12 is effectively limited and fixed in all directions along the plane of the first mounting surface 1111, thereby improving the installation stability of the heating film 12.

[0053] Optionally, in some embodiments, the heating film 12 may be bonded to the first mounting portion 110 , which helps to improve the installation stability of the heating film 12 .

[0054] Optionally, in some embodiments, glue may be provided on the circumference of the aforementioned limiting structure, and the glue is used to firmly connect the heating film 12 to the limiting structure on the first mounting surface 1111, thereby strengthening the connection strength between the heating film 12 and the first mounting portion 110.

[0055] Optionally, in some embodiments, the heating film 12 may be adhered to the first mounting surface 1111 .

[0056] Specifically, adhesive may also be provided on the first mounting surface 1111. For example, when the heating film 12 is attached to the first mounting surface 1111, pressure may be applied to the surface of the heating film 12 using a press to ensure that the adhesive can fully spread and fill the gap between the heating film 12 and the first mounting surface 1111 as much as possible, thereby improving the bonding strength between the heating film 12 and the first mounting surface 1111. It is understood that in some embodiments, adhesive may be provided both in the circumferential direction of the limiting structure and on the first mounting surface 1111.

[0057] Optionally, the roughness of the first mounting surface 1111 can be set to, but is not limited to, less than or equal to 0.3, such as 0.3, 0.25, 0.2, 0.15, 0.1, or 0.05. This helps improve the flatness of the first mounting surface 1111, thereby improving the fit of the heating film 12 on the first mounting surface 1111. In addition, this setting also helps improve the heating uniformity of the heating film 12 on the first mounting surface 1111, thereby improving the heating effect on the lidar 11.

[0058] Optionally, see Figure 1 and Figure 2 The mounting groove 211 may be provided with a locking portion 2111, the mounting bracket 13 further includes a locking member 300, the laser radar 11 has a fixing portion 11a, the fixing portion 11a is aligned with the locking portion 2111, and the locking member 300 is used to be fixed to the locking portion 2111 on the side of the second mounting portion 210 away from the laser radar 11.

[0059] Optionally, the mounting groove 211 may be designed to be square, and the locking portions 2111 may be, but are not limited to, disposed at four right-angled positions of the mounting groove 211 .

[0060] In this way, in the process of fixing the laser radar 11 on the second bracket 200, you only need to place the laser radar 11 in the direction facing the installation groove 211, and then perform the locking operation of the locking piece 300 from the side of the second installation part 210 away from the laser radar 11, thereby improving the convenience of user operation.

[0061] Optionally, the fixing portion 11a and the locking portion 2111 may be, but are not limited to, implemented as screw holes, and the locking member 300 may be, but are not limited to, implemented as a screw. Of course, in other embodiments, the fixing portion 11a and the locking portion 2111 may be, but are not limited to, implemented as snap-fit ​​holes, and the locking member 300 may be, but are not limited to, implemented as a snap-fit ​​post.

[0062] Optionally, combined Figure 1 and Figure 2 As shown, a reinforcing rib 2112 is provided on the side of the second mounting portion 210 facing away from the laser radar 11, which can strengthen the structural strength of the second mounting portion 210 and also help prevent the second bracket 200 from being deformed when the locking operation of the locking member 300 is performed.

[0063] Optionally, see Figure 4 An adhesive body 500 is provided on the side of the first bracket 100 facing away from the second bracket 200. The adhesive body 500 is used to fix the laser radar device 10 on the vehicle. This can enhance the installation stability of the laser radar device 10 and reduce the shaking of the laser radar device 10 during the driving of the vehicle.

[0064] Preferably, see Figure 4 The adhesive body 500 can be evenly arranged along the blank positions of the circumference of the first bracket 100, which helps to increase the bonding area of ​​the first bracket 100 on the vehicle, thereby improving the installation stability of the laser radar device 10 on the vehicle.

[0065] Optionally, the first bracket 100 may be made of plastic, and the second bracket 200 may be made of metal.

[0066] Specifically, the use of metal for the second bracket 200 helps to improve the structural strength of the second bracket 200, thereby improving the installation stability of the laser radar 11 on the second bracket 200. For example, the second bracket 200 made of metal can provide sufficient strength support for the bolted connection between the second bracket 200 and the laser radar 11. In addition, the combination of the metal material of the second bracket 200 and the plastic material of the first bracket 100 helps to reduce abnormal noise caused by collisions between the first bracket 100 and the second bracket 200, thereby improving the quietness of the laser radar device 10 during operation.

[0067] Optionally, see Figure 3 The heating film 12 also includes an electric wire 125 and a connector 126. A corresponding bayonet 130 for clamping the aforementioned connector 126 is provided on the bottom surface 120 of the first bracket 100. The bayonet 130 is used to fix the connector 126. This can reduce the abnormal noise caused by the shaking of the connector 126 and the electric wire 125, and further improve the stability and quietness of the laser radar device 10 during operation.

[0068] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
