Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted cameras, and more specifically, to a vehicle-mounted camera mounting bracket. Background Technology
[0002] As a crucial device for vehicle safety assistance and monitoring, the installation stability and angle adjustability of in-vehicle cameras directly affect their effectiveness. The mounting bracket is a core component for achieving these functions. Existing in-vehicle camera brackets have several shortcomings: Regarding angle adjustment, separate operations are often required in both horizontal and vertical directions, making the adjustment process cumbersome. Furthermore, the fixing structure is prone to loosening, making it difficult to achieve multi-dimensional simultaneous positioning and affecting the precise fixation of the camera angle. In terms of installation and fixation, the bracket relies heavily on adhesive layers adhering to the vehicle's surface. However, the temperature fluctuations in the vehicle environment are significant. High temperatures can cause the adhesive layer to lose its stickiness, while low temperatures can cause it to harden and become brittle. Existing brackets lack specific temperature control measures, making them prone to loosening due to adhesive failure. Utility Model Content

[0018] Example 1
[0019] like Figure 1-2 The vehicle-mounted camera mounting bracket shown includes a base 1 and a support rod 2 mounted on the top of the base 1. A sleeve 3 that rotates around the support rod 2 is sleeved on the outside of the top of the support rod 2. An opening 4 is opened at the top of the sleeve 3. A rotating universal joint 5 is provided inside the opening 4. The universal joint 5 extends to the outside of the sleeve 3 and is used to connect the vehicle-mounted camera. A movable limiting member 6 passes through the outer wall of the sleeve 3. By rotating the limiting member 6, the rotation between the sleeve 3 and the support rod 2 and the rotation of the universal joint 5 in the opening 4 are simultaneously limited.
[0020] Based on the above, the base 1 provides the installation foundation for the whole, and the support rod 2 is fixed to the top of the base 1 as the main support. The sleeve 3 is fitted on the top of the support rod 2 and can rotate freely around the support rod 2 to realize the horizontal angle adjustment of the camera. The universal joint 5 is located in the opening 4 at the top of the sleeve 3 and can rotate flexibly in the opening 4. The part of it extending to the outside of the sleeve 3 is connected to the camera to realize the three-dimensional angle adjustment of the camera such as tilt and tilt. The limiting member 6 penetrates the outer wall of the sleeve 3. By rotating the limiting member 6, the relative rotation of the sleeve 3 and the support rod 2 and the rotation of the universal joint 5 in the opening 4 can be restricted at the same time, thereby fixing the angle of the camera after adjustment. The cooperation between the sleeve 3 and the universal joint 5 realizes the multi-dimensional adjustment of the camera. The synchronous limiting design of the limiting member 6 simplifies the operation, eliminates the need for separate fixing, and improves the adjustment efficiency.
[0021] The support rod 2 is hollow inside, and a recessed limiting groove 7 is provided on the outer wall of the support rod 2 located inside the sleeve 3.
[0022] Based on the above, the hollow design of the support rod 2 reduces the overall weight and reserves space for possible internal wiring, etc. The outer wall of the support rod 2 inside the sleeve 3 is provided with a limiting groove 7. The limiting groove 7 cooperates with the limiting member 6. When the limiting member 6 acts on the limiting groove 7, the rotation of the sleeve 3 around the support rod 2 is restricted by increasing the friction force, thereby improving the stability of the horizontal angle.
[0023] Furthermore, the hollow structure balances lightweight and functionality, and the limiting groove 7 enhances the fixing effect of the limiting component 6, preventing the sleeve 3 from accidentally falling off.
[0024] The limiting component 6 includes a limiting screw 8 and a pressure rod 9 that pass through the sleeve 3. The limiting screw 8 and the pressure rod 9 are parallel. The sleeve 3 has a screw hole 10 that mates with the limiting screw 8 and a through hole 11 that mates with the pressure rod 9. The end of the limiting screw 8 located inside the sleeve 3 abuts against the inner wall of the limiting groove 7. The end of the limiting screw 8 located outside the sleeve 3 is equipped with a knob 12 that is coaxially arranged with the limiting screw 8.
[0025] Based on the above, the limiting component 6 consists of a limiting screw 8 and a pressure rod 9, which are arranged in parallel and pass through the screw hole 10 and through hole 11 on the sleeve 3, respectively. When the knob 12 is rotated, the limiting screw 8 moves axially along the screw hole 10, and its end located in the sleeve 3 abuts against the limiting groove 7 of the support rod 2, limiting the rotation of the sleeve 3 through thread locking and end face friction. The knob 12 and the limiting screw 8 are designed to be coaxial to ensure stable force transmission and facilitate precise control of the limiting force.
[0026] The threaded engagement between the screw and the screw hole 10 enables adjustable limiting force. The parallel limiting screw 8 and pressure rod 9 provide a structural basis for synchronous limiting. The knob 12 is easy to operate and has high adjustment accuracy.
[0027] The end of the pressure rod 9 located inside the sleeve 3 abuts against the universal joint 5, limiting the universal joint 5 within the opening 4. The end of the pressure rod 9 located outside the sleeve 3 is fitted with a rotating ball 13, which is in contact with the outer wall of the knob 12.
[0028] Based on the above, the pressure rod 9 passes through the through hole 11 of the sleeve 3, and its end located inside the sleeve 3 directly abuts against the universal joint 5. By limiting the rotation of the universal joint 5 in the opening 4 through pressure, the three-dimensional angle is fixed. The ball 13 at the outer end of the pressure rod 9 is in contact with the outer wall of the knob 12. When the knob 12 is rotated, the ball 13 rolls with the knob 12, converting the sliding friction between the knob 12 and the pressure rod 9 into rolling friction, reducing wear, and at the same time, enabling the knob 12 to push the pressure rod 9 into the sleeve 3 synchronously when it rotates.
[0029] Furthermore, the ball bearing 13 design reduces frictional loss between the knob 12 and the pressure rod 9, extending the component's lifespan; the pressure rod 9 directly abuts against the universal coupling 5, ensuring reliable fixation of the three-dimensional angle, and works in conjunction with the limit screw 8 to achieve synchronous limiting.
[0030] The pressure rod 9 is fitted with a return spring 14. One end of the return spring 14 is fixed to the outer wall of the sleeve 3 and the other end is fixed to the outer wall of the pressure rod 9. When the knob 12 is released and the limiting screw 8 is removed from the limiting groove 7, the elastic force of the return spring 14 drives the pressure rod 9 to move out of the sleeve 3, releasing the clamping of the universal joint 5, so that the universal joint 5 can resume its rotation ability and make it easy to readjust the angle.
[0031] Furthermore, the return spring 14 enables the pressure rod 9 to automatically reset, eliminating the need to manually pull the pressure rod 9, simplifying the operation process and ensuring adjustment flexibility.
[0032] The universal joint 5 includes a ball bearing 15 that is locked between the inside of the opening 4 and the top of the support rod 2, and a connecting rod 16 connected to the outer wall of the ball bearing 15. The diameter of the ball bearing 15 is larger than the inner diameter of the opening 4. The connecting rod 16 extends to the outside of the sleeve 3. A recessed locking groove 17 is provided at the top edge of the sleeve 3. The locking groove 17 penetrates the sleeve 3 and communicates with the opening 4.
[0033] Based on the above, the ball bearing 15 of the universal joint 5 is locked between the inner side of the opening 4 of the sleeve 3 and the top of the support rod 2. Since the diameter of the ball bearing 15 is larger than the inner diameter of the opening 4, it can prevent the ball bearing 15 from falling out of the opening 4. The ball bearing 15 can rotate freely in the opening 4, driving the connecting rod 16 connected to its outer wall to rotate synchronously. The connecting rod 16 is connected to the camera to realize multi-angle adjustment. The locking groove 17 at the top of the sleeve 3 is connected to the opening 4. When the ball bearing 15 rotates, part of the structure can be embedded in the locking groove 17 to help limit the rotation range of the ball bearing 15 and avoid excessive rotation that could damage the components.
[0034] Example 2
[0035] like Figure 1-3 As shown, based on the first embodiment, this embodiment adds a semiconductor cooling chip 24 and a temperature sensor 25 structure, and sets an H-bridge circuit on the circuit of the semiconductor cooling chip 24. This part of the structure is set inside the base 1, specifically as follows:
[0036] The base 1 includes an outer cover 18 and a copper substrate 19 located at the bottom of the outer cover 18. An adjustment chamber 20 is formed between the copper substrate 19 and the outer cover 18. A turbine fan 21 is installed at the top of the inner cavity of the adjustment chamber 20. The air inlet of the turbine fan 21 faces downward. An air outlet pipe 22 is connected to the air outlet of the turbine fan. The air outlet pipe 22 passes through the base 1 and communicates with the outside. Several air inlet slots 23 communicating with the inside of the adjustment chamber 20 are opened on the outer wall of the base 1.
[0037] Furthermore, the outer casing 18 and the copper substrate 19 together form a closed regulating chamber 20 as the core area for temperature control; the turbine fan 21 is installed on the top of the regulating chamber 20 with the air inlet facing downwards, which can draw in air from the regulating chamber 20; the air outlet duct 22 connects to the air outlet of the turbine fan 21 and passes through the base 1 to exhaust air to the outside; the air inlet slot 23 is opened on the outer wall of the base 1 and communicates with the regulating chamber 20 to replenish fresh air from the outside, forming an airflow circulation channel of "air inlet slot 23 → regulating chamber 20 → turbine fan 21 → air outlet duct 22", providing an airflow basis for heat dissipation.
[0038] The copper substrate 19 is attached to the top of the inner side of the regulating chamber 20 with a semiconductor cooling chip 24 and a temperature sensor 25. The semiconductor cooling chip 24 is located directly below the air inlet of the turbine fan 21. An adhesive layer 26 is attached to the bottom of the copper substrate 19.
[0039] Based on the above, the copper substrate 19 has both load-bearing and heat-conducting functions, and the adhesive layer 26 at its bottom is used to fix the bracket to the vehicle mounting surface; the top of the copper substrate 19 in the regulating chamber 20 is attached to the semiconductor cooling chip 24 and the temperature sensor 25, and the temperature sensor 25 monitors the temperature of the copper substrate 19 and the adhesive layer 26 in real time; the semiconductor cooling chip 24 is located directly below the air inlet of the turbine fan 21 and can absorb or release heat through the copper substrate 19.
[0040] Furthermore, the temperature sensor 25 is connected to the microprocessor, while the thermoelectric cooler 24 is connected to the H-bridge circuit. After receiving the temperature information, the microprocessor controls the thermoelectric cooler 24 according to the preset threshold and program.
[0041] When the temperature is too high, the microprocessor controls the thermoelectric cooler 24 to start the cooling mode. The absorbed heat is drawn in by the turbine fan 21 and discharged through the air outlet duct 22. When the temperature is too low, the microprocessor controls and triggers the H-bridge circuit to work. The H-bridge circuit changes the current direction of the thermoelectric cooler 24, taking advantage of the characteristic that "the current direction determines the working mode", and switches it to the heating mode. The released heat is transferred to the adhesive layer 26 through the copper substrate 19, preventing the adhesive layer 26 from hardening due to low temperature. By changing the current direction flowing through the thermoelectric cooler 24, the stable switching between cooling and heating modes is achieved, ensuring reliable current conversion.
[0042] Once the bracket is installed, the power supply components of the device can be connected to the vehicle's power supply interface via cables to provide power to the device.
