[0002] In related technologies, there is only a fixed heating control strategy for the signal transmission area in the vehicle glass assembly, without considering changes in surrounding components. Especially after repeated heating in winter, the cumulative temperature of the support frame is high, causing various precipitates to form in the adhesive between the support frame and the glass substrate. These precipitates block the signal transmission area, causing the detection sensor to malfunction. They also cause deformation of the support frame material, resulting in abnormal noises, and affect the connection performance between the support frame and the glass substrate.

[0003] Meanwhile, the side of the support frame facing the glass substrate is usually provided with an anti-glare film. After repeated heating in winter, the cumulative temperature of the support frame is high, which can easily damage the anti-glare film, reduce its anti-glare performance, and affect the operation of the detection sensor.

[0023] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0024] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0025] For example, the solvent of the adhesive between the support frame and the glass substrate is petroleum ether, which is easily volatilized and condensed on the inner surface of the glass substrate under high temperature conditions to form an oil film. The shape of the oil film radiates inward from the edge of the adhesive.

[0026] For example, the light-blocking paint printed on a light-blocking mask may release impurities under high-temperature conditions. For light-blocking paint, after the paint and hardener are mixed, it is sprayed onto the surface of the material to first form a wet film, and then cured at high temperature to finally form a highly cross-linked network polymer paint film. However, the uncured and incompletely cured paint wet film is a mixture / solution of organic matter, such as composed of alkanolamines, solvents, and isocyanates, which are very easy to precipitate, and alkanolamines, solvents, and isocyanates evaporate at high temperatures to form an oil film.

[0027] In view of this, in order to solve the above problems, please refer to the following: Figures 1-3 This embodiment provides a bracket assembly for mounting a detection sensor 13 to a glass substrate 11. The bracket assembly includes a support frame 12, a first heating element 141, and a temperature sensor 15.

[0028] The glass substrate 11 has a signal transmission area, and the support frame 12 includes a light shield. The support frame 12 protrudes in a direction away from the glass substrate 11 to form the light shield, so that the signal transmission area and the light shield together form the field of view space of the detection sensor 13. The first heating element 141 is disposed on the light shield. The temperature sensor 15 is used to acquire the real-time temperature information of the first heating element 141. When the real-time temperature is not within the preset temperature range, the first heating element 141 is controlled to adjust the real-time temperature so that the real-time temperature is within the preset temperature range.

[0029] Specifically, this embodiment also provides a vehicle window glass assembly 1, which includes a glass substrate 11 and a bracket assembly as described above in this application. The bracket assembly is used to mount a detection sensor 13 to the glass substrate 11.

[0030] Optionally, the glass substrate 11 can be used as the windshield, rear windshield, sunroof, side window, corner window, etc. of a vehicle. Preferably, the glass substrate 11 is used as the windshield of a vehicle.

[0031] Optionally, the glass substrate 11 is a single piece of glass or a laminated glass. When the glass substrate 11 is a laminated glass, the laminated glass includes a first glass plate, an intermediate adhesive layer, and a second glass plate stacked sequentially.

[0032] The support frame 12 serves as a basic support structure, providing a stable mounting platform for the detection sensor 13, the first heating element 141, and the temperature sensor 15, and also for connecting the glass substrate 11. Optionally, the support frame 12 is bonded to the glass substrate 11.

[0033] The support frame 12 is made of plastic. The support frame 12 is a plastic component. For example, the support frame 12 is made of a high-strength plastic material.

[0034] Optionally, the support frame 12 and the glass substrate 11 are bonded together using an adhesive. The shear force of the adhesive is ≥100N. For example, the support frame 12 is bonded to the glass substrate 11 using PU adhesive.

[0035] The detection sensor 13 is used to acquire external environmental information. The detection sensor 13 is used to transmit and / or receive detection signals. The detection sensor 13 is selected from one or a combination of a camera and a lidar. The support frame 12 has a through-hole that extends through the support frame 12 along its thickness direction. The lens of the detection sensor 13 is correspondingly positioned to the through-hole. The detection signal emitted by the detection sensor 13 can pass through the through-hole and the glass substrate 11, and the detection signal reflected from the outside can pass through the through-hole and the glass substrate 11 and be received by the detection sensor 13.

[0036] For example, the detection sensor 13 is directly mounted on the support frame 12, or the detection sensor 13 is indirectly mounted on the support frame 12 through other components. Optionally, the detection sensor 13 and the support frame 12 are detachably connected. Further optionally, the connection method between the detection sensor 13 and the support frame 12 includes, but is not limited to, threaded connection, adhesive connection, snap-fit, etc., and this embodiment does not limit this.

[0037] The first heating element 141 is used for heating.

[0038] Optionally, the first heating element 141 is disposed adjacent to the temperature sensor 15.

[0039] Optionally, the first heating element 141 and the temperature sensor 15 are integrated into one component.

[0040] In one embodiment, the first heating element 141 is a heating film disposed on the light shield, and the heating film is used to emit heat radiation toward the field of view of the detection sensor.

[0041] The heating film is attached to the light shield and covers the detection sensor 13. It provides uniform heating, high thermal efficiency, and reduces ineffective heat loss. The heating film does not take up space and does not affect the assembly of the glass substrate 11 and the support frame 12.

[0042] Optionally, the heating film is attached to the light shield and covers the temperature sensor 15.

[0043] The step of controlling the first heating element 141 includes: controlling the heating film.

[0044] For example, by using a PIN connector to control the on / off state of the heating film in connection with the vehicle wiring harness, defrosting and defogging of the signal transmission area can be achieved.

[0045] Temperature sensor 15 is used to acquire real-time temperature information. Optionally, temperature sensor 15 is selected from NTC thermistors, which are key components that can utilize the negative temperature coefficient characteristics of semiconductor materials for temperature measurement, and whose resistance decreases exponentially with increasing temperature.

[0046] For example, the temperature sensor 15 is directly mounted to the support frame 12, or the temperature sensor 15 is indirectly mounted to the support frame 12 through other components. Optionally, the temperature sensor 15 and the support frame 12 are detachably connected. Further optionally, the connection method between the temperature sensor 15 and the support frame 12 includes, but is not limited to, threaded connection, adhesive connection, snap-fit, etc., and this embodiment does not limit this.

[0047] The detection sensor 13 and the temperature sensor 15 are set in a corresponding manner, which can also be understood as the orthographic projection of the detection sensor 13 on the support frame 12 and the orthographic projection of the temperature sensor 15 on the support frame 12 at least partially coincide.

[0048] Typically, the temperature at the detection sensor 13 within the support frame 12 is higher than the temperature of the surrounding area. Therefore, in this embodiment, the temperature sensor 15 is placed in the corresponding area of ​​the detection sensor 13, enabling real-time monitoring and accurate detection of the temperature in high-risk areas. This provides reliable data support for the precise control of the first heating element 141, which helps to avoid excessively high or low temperatures in high-risk areas and prevents the precipitation of various substances from surrounding components at high temperatures. It also prevents the risk of adhesive precipitation, deformation of the support frame 12, and damage to the light-blocking paint caused by the accumulation of high temperatures in the support frame 12.

[0049] Optionally, this application also provides a method for heating the vehicle window glass assembly 1, comprising: S100, acquire the real-time temperature information of the temperature sensor 15.

[0050] S200, determine whether the real-time temperature is within the preset temperature range.

[0051] Optionally, the preset temperature range is 90℃~93℃, specifically 90℃, 90.5℃, 91℃, 91.5℃, 92℃, 92.5℃, or 93℃, etc.

[0052] S300, if the real-time temperature is not within the preset temperature range, then control the first heating element 141 to bring the real-time temperature within the preset temperature range.

[0053] For example, if the real-time temperature obtained by the temperature sensor 15 is 80°C, then it is determined that the real-time temperature of 80°C is not within the preset temperature range of 90°C to 93°C. Then, the first heating element 141 is controlled to heat the temperature so that the real-time temperature obtained by the temperature sensor 15 reaches 90°C to 93°C.

[0054] In summary, the bracket assembly provided in this embodiment, by setting a temperature sensor 15 at the position corresponding to the detection sensor 13, allows the temperature sensor 15 to monitor the temperature in real time. The first heating element 141 operates according to the real-time temperature, keeping the temperature of the light shield within a preset temperature range. This avoids excessively high or low temperatures, thereby preventing the precipitation of various substances from surrounding components at high temperatures. It also prevents the risk of adhesive precipitation, deformation of the support frame 12, and damage to the matting film caused by the accumulation of high temperatures on the support frame 12. While improving the reliability of the connection between the support frame 12 and the glass substrate 11 and ensuring the normal operation of the detection sensor 13, it also enables rapid defrosting and defogging of the signal transmission area.

[0055] Furthermore, when the real-time temperature is not within the preset temperature range, the window glass assembly 1 satisfies the following conditions: When the real-time temperature is not greater than the minimum value of the preset temperature range, the first heating element 141 heats up to bring the real-time temperature within the preset temperature range.

[0056] When the real-time temperature is not less than the maximum value of the preset temperature range, the first heating element 141 stops heating.

[0057] Alternatively, please refer to Figure 4 The heating method for the vehicle window glass assembly 1 further includes: After step S200, which determines whether the real-time temperature is within a preset temperature range, the method further includes: S310, if the real-time temperature is not within the preset temperature range, then determine whether the real-time temperature is not greater than the minimum value of the preset temperature range, and determine whether the real-time temperature is not less than the maximum value of the preset temperature range.

[0058] In one embodiment, the minimum value of the preset temperature range is 90°C, and the maximum value of the preset temperature range is 93°C.

[0059] This embodiment limits the preset temperature range to a minimum of 90°C and a maximum of 93°C, which can meet the defrosting, defogging, and de-icing requirements of the signal transmission area, while avoiding the risks of adhesive precipitation, matte film damage, aging of support frame 12, and deformation of support frame 12 caused by excessive temperature.

[0060] S320, if the real-time temperature is not greater than the minimum value of the preset temperature range, then control the first heating element 141 to heat up so that the real-time temperature is within the preset temperature range.

[0061] For example, the real-time temperature obtained by the temperature sensor 15 is 80°C. Then, it is determined that the real-time temperature of 80°C is not within the preset temperature range of 90°C to 93°C. Next, it is determined that the real-time temperature of 80°C is less than the minimum value of the preset temperature range of 90°C. Subsequently, the first heating element 141 is controlled to heat the temperature so that the real-time temperature obtained by the temperature sensor 15 reaches 90°C to 93°C.

[0062] S330, if the real-time temperature is not less than the maximum value of the preset temperature range, then control the first heating element 141 to stop heating.

[0063] For example, if the real-time temperature obtained by the temperature sensor 15 is 100℃, then it is determined that the real-time temperature of 100℃ is not within the preset temperature range of 90℃~93℃. Next, it is determined that the real-time temperature of 100℃ is greater than the maximum value of the preset temperature range of 93℃. Subsequently, by controlling the first heating element 141 to stop heating, the signal transmission area is allowed to cool down naturally, so that the real-time temperature obtained by the temperature sensor 15 reaches 90℃~93℃.

[0064] Therefore, this embodiment further optimizes the heating control of the signal transmission area based on real-time temperature by further defining the first heating element 141. When the real-time temperature is not within the preset temperature range, the first heating element 141 is controlled to heat when the temperature is low and to stop heating when the temperature is high. This can both ensure the defogging and de-icing effect when the real-time temperature is low and stop heating when the real-time temperature is high, thus suppressing heat accumulation and preventing the precipitation of various substances in the surrounding components at high temperatures. This also prevents the risk of adhesive precipitation, deformation of the support frame 12, and damage to the matte film caused by the accumulation of high temperature in the support frame 12.

[0065] Furthermore, the first heating element 141 is used to perform the Nth heating, and the preset heating time for the Nth heating is T. N The temperature sensor 15 is also used to obtain the temperature at the Nth time after the Nth heating, and the window glass assembly 1 satisfies the following conditions: When the temperature at the Nth time is within the preset temperature range, the first heating element 141 stops heating.

[0066] When the temperature at time N is not within the preset temperature range, and the temperature at time N is not greater than the minimum value of the preset temperature range, the first heating element 141 performs the (N+1)th heating, and the preset heating time for the (N+1)th heating is T. N+1 .

[0067] Alternatively, please refer to Figure 5 The heating method for the vehicle window glass assembly 1 further includes: Step S320, which controls the heating of the first heating element 141, includes: S321, control the first heating element 141 to perform the Nth heating, the preset heating time of the Nth heating is T. N .

[0068] N is an integer, and N can be specifically represented as one, two, three, four, five, etc.

[0069] Preferably, the total number of heating cycles for the first heating element 141 is less than three until the real-time temperature is within the preset temperature range.

[0070] Optionally, the preset heating time T for the Nth heating is... N The duration is 10s to 30s, and specific examples include 10s, 12s, 14s, 16s, 18s, 20s, 22s, 24s, 26s, 28s, and 30s.

[0071] S322, obtain the temperature of the temperature sensor 15 at the Nth time after the Nth heating, and determine whether the temperature at the Nth time is within the preset temperature range.

[0072] S323, if the temperature at the Nth time is within the preset temperature range, then control the first heating element 141 to stop heating.

[0073] S324, if the temperature at time N is not within the preset temperature range, then determine whether the temperature at time N is not greater than the minimum value of the preset temperature range.

[0074] S325, if the temperature at the Nth time is not greater than the minimum value of the preset temperature range, then control the first heating element 141 to perform the (N+1)th heating, the preset heating time of the (N+1)th heating is T. N+1 .

[0075] Optionally, the preset heating time T for the (N+1)th heating is... N+1 The min time is 10s to 30s. For example, it can be 10s, 12s, 14s, 16s, 18s, 20s, 22s, 24s, 26s, 28s, or 30s.

[0076] In one embodiment, the preset heating time T for the Nth heating is... N The preset heating time for the (N+1)th heating is T. N+1 .

[0077] Preferably, the preset heating time T for the Nth heating is... N The preset heating time for the (N+1)th heating is T. N+1 .

[0078] More preferably, the preset heating time T for the Nth heating is... N For 25s~30s; The preset heating time T for the (N+1)th heating cycle N+1 For 20s~25s; The preset heating time T for the (N+2)th heating cycle N+1 It lasts for 15 to 20 seconds.

[0079] For example, the first heating element 141 is controlled to perform the first heating, and the preset heating time for the first heating is T1, which is 30 seconds. Then, the temperature of the temperature sensor 15 at the first moment after the first heating is obtained, and it is determined whether the temperature at the first moment is within the preset temperature range.

[0080] If the temperature at the first moment is 91℃, which is within the preset temperature range of 90℃~93℃, then the first heating element 141 is controlled to stop heating.

[0081] If the temperature at the first moment is 60℃, which is not within the preset temperature range of 90℃~93℃, then determine whether the temperature at the first moment is not greater than the minimum value of the preset temperature range of 90℃.

[0082] If the temperature at the first moment is 60℃, which is less than the minimum value of the preset temperature range of 90℃, then the first heating element 141 is controlled to perform a second heating, and the preset heating time for the second heating is T2.

[0083] Repeat the above steps until the temperature sensor 15 detects a temperature of 90℃~93℃ at a certain moment.

[0084] Therefore, by using the first heating element 141 to heat in stages, this embodiment not only avoids the problem of local overheating caused by excessively long single heating time and facilitates precise temperature control, but also allows for dynamic adjustment of the number of heating cycles to adapt to different initial temperatures and environmental conditions. This further avoids the precipitation of various substances from surrounding components at high temperatures and prevents the risk of adhesive precipitation, deformation of the support frame 12, and damage to the matte film caused by the accumulation of high temperatures in the support frame 12.

[0085] Furthermore, by controlling the heating time for each cycle and preferably decreasing the heating time in stages, the problem of local overheating caused by excessively long heating times is further avoided, and the temperature is controlled more precisely.

[0086] Furthermore, when the real-time temperature is within the preset temperature range, the heating element at the front-view camera of the window glass assembly 1 is heated; and / or, the heating element at the front side-view camera of the window glass assembly 1 is heated.

[0087] Alternatively, please refer to Figure 6 The heating method for the vehicle window glass assembly 1 further includes: After step S200, which determines whether the real-time temperature is within a preset temperature range, the method further includes: S400, if the real-time temperature is within the preset temperature range, then control the heating part at the front view camera corresponding to the window glass assembly 1 to heat up, and / or control the heating part at the front side view camera corresponding to the window glass assembly 1 to heat up.

[0088] Optionally, prior to the step of controlling the heating element at the forward-looking and / or front-side-looking camera, the method further includes: Determine that temperature sensor 15 is in a non-faulty state, and determine whether the real-time temperature is in an effective state.

[0089] For example, when the NTC temperature sensor 15 is in a non-faulty state and the real-time temperature is in a valid state, the MD calls the cross-domain interface to request front-view and / or side-front-view heating.

[0090] This embodiment first determines the status of the temperature sensor 15 and the real-time temperature to prevent incorrect heating from starting when the sensor malfunctions, thus avoiding overheating or energy waste caused by incorrect heating.

[0091] Optionally, the heating element at the front-view and / or front-side view camera can be controlled by calling a cross-domain interface.

[0092] Therefore, this embodiment uses a temperature sensor 15 located at the corresponding position of the detection sensor 13 to obtain the real-time temperature, determine the heating logic at the front-view and / or front-side view cameras, reuse the temperature sensor 15, save the cost of arranging multiple independent temperature sensors 15, and facilitate the coordinated heating of multiple camera areas in the vehicle glass area, improve the overall field of vision and driving assistance reliability, realize the heating integration of the vehicle, simplify the system logic, and improve the efficiency of the vehicle heating system.

[0093] This embodiment also provides a vehicle window glass assembly 1, which includes a glass substrate 11 and a bracket assembly as described above in this application. The bracket assembly is used to mount a detection sensor 13 to the glass substrate 11.

[0094] The vehicle window glass assembly provided in this application adopts the bracket assembly provided above. The bracket assembly has a temperature sensor 15 set at the position corresponding to the detection sensor 13. The temperature sensor 15 can monitor the temperature in real time. The first heating element 141 works according to the real-time temperature to keep the temperature of the sunshade within the preset temperature range, avoiding excessively high or low temperatures. This prevents the precipitation of various substances from surrounding components at high temperatures and prevents the risk of adhesive precipitation, deformation of the support frame 12, and damage to the matte film caused by the accumulation of high temperature in the support frame 12. While improving the connection reliability between the support frame 12 and the glass substrate 11 and ensuring that the detection sensor 13 can work normally, it can also achieve rapid defrosting and defogging of the signal transmission area.

[0095] In one embodiment, the window glass assembly 1 further includes a second heating element 142, which is disposed in the signal transmission area of ​​the glass substrate 11.

[0096] The second heating element 142 is used to defrost and defog the signal transmission area.

[0097] Optionally, the second heating element 142 is a heating wire.

[0098] The second heating element 142 can apply thermal radiation to heat the glass substrate 11.

[0099] Furthermore, the heating wire is disposed on the inner surface of the glass substrate 11 facing the support frame 12.

[0100] Furthermore, the heating line includes multiple laterally extending lateral heating sections, with adjacent lateral heating sections connected together.

[0101] Optionally, the heating wire is a metal wire selected from at least one of silver wire, copper wire, tungsten wire, or enameled wire.

[0102] Furthermore, the second heating element 142 is arranged around the detection sensor 13 and the temperature sensor 15 of the bracket assembly.

[0103] This embodiment improves the de-icing and defogging effect by providing a second heating element 142, which is located around the detection sensor 13. This results in a more uniform heating temperature, further avoids localized high temperatures, and enhances the de-icing and defogging effect.

[0104] Optionally, the heating method for the window glass assembly 1 further includes controlling at least one of the heating wire and the heating film.

[0105] For example, the heating wire can be controlled separately.

[0106] For example, the heating film can be controlled separately.

[0107] For example, simultaneously controlling the heating wire and the heating film.

[0108] The heating wire and heating film can be controlled individually or in combination, which improves the flexibility of temperature control and can be adapted to different low-temperature working conditions.

[0109] Heating efficiency can be improved by simultaneously controlling the heating wire and the heating film, thereby enhancing the defrosting and defogging effect on the signal transmission area.

[0110] For example, silver paste heating wires are uniformly arranged on the inner surface of the glass substrate 11, except for the area of ​​the detection sensor 13. By welding a PIN connector to control the connection and disconnection with the vehicle wiring harness control logic, composite heating is achieved together with the heating wires and heating film.

[0111] This application also provides a controller for executing the heating method for a vehicle window glass assembly as described above. The controller includes an acquisition unit, a judgment unit, and an adjustment unit. The acquisition unit is used to acquire the real-time temperature of a temperature sensor. The judgment unit is used to determine whether the real-time temperature is within a preset temperature range. When the real-time temperature is not within the preset temperature range, the adjustment unit is used to control a first heating element to bring the real-time temperature within the preset temperature range.

[0112] The controller provided in this embodiment can acquire the real-time temperature of the temperature sensor through an acquisition unit, and then determine whether the real-time temperature is within a preset temperature range through a judgment unit. When the real-time temperature is not within the preset temperature range, the adjustment unit controls the first heating element to bring the real-time temperature within the preset temperature range.

[0113] In summary, through the cooperation between the acquisition unit, the judgment unit, and the adjustment unit, the first heating element operates according to the real-time temperature, maintaining the temperature of the light shield within the preset temperature range. This avoids excessively high or low temperatures, thereby preventing the precipitation of various substances from surrounding components at high temperatures. It also prevents the risk of adhesive precipitation, support frame deformation, and damage to the matting film caused by the accumulation of high temperatures in the support frame. In addition to improving the reliability of the connection between the support frame and the glass substrate and ensuring the normal operation of the detection sensor, it also enables rapid defrosting and defogging of the signal transmission area.

[0114] Optionally, this application also provides a control system for a vehicle window glass assembly, the control system for the vehicle window glass assembly including the controller and the vehicle window glass assembly as provided above in this application.

[0115] This application also provides a vehicle, the vehicle including a body and a window glass assembly as described above, the window glass assembly being disposed on the body.

[0116] The vehicle provided in this application, by adopting the window glass assembly provided above, has a temperature sensor installed at the position corresponding to the detection sensor in the bracket assembly. The temperature sensor can monitor the temperature in real time, and the first heating element works according to the real-time temperature to maintain the temperature of the sunshade within a preset temperature range, avoiding excessively high or low temperatures. This prevents various substances from being released from surrounding components at high temperatures, and prevents the risk of adhesive release, bracket deformation, and damage to the matte film caused by the accumulation of high temperatures in the support frame. While improving the reliability of the connection between the support frame and the glass substrate and ensuring that the detection sensor can work normally, it can also achieve rapid defrosting and defogging of the signal transmission area.
