Description

Technical Field

[0001] This application relates to the field of equipment protection technology, specifically to an equipment heat dissipation adjustment device and a VR device. Background Technology

[0002] The core components of VR devices mainly consist of processors, displays, optical lenses, and sensors, used to present virtual scenes.

[0003] The high-performance processors, displays, and sensors in VR devices generate a lot of heat during operation. Cooling fans can remove the heat from the device through forced convection, preventing problems such as performance degradation, crashes, or even hardware damage caused by overheating.

[0004] To maintain a high level of user immersion, cooling fans should operate as quietly as possible. Higher fan speeds result in better cooling; however, higher speeds also lead to greater noise, negatively impacting the user experience. Therefore, a trade-off must be struck. Current technology typically reduces noise by collecting factory test data (noise levels corresponding to different fan speeds) and then limiting the fan's actual maximum operating speed. However, this approach fails to utilize the fan's full cooling potential. Utility Model Content

[0030] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0031] Please refer to Figure 1 It shows a schematic diagram of the structure of a device heat dissipation adjustment device provided in some embodiments of this application, such as Figure 1 As shown, the heat dissipation adjustment device 10 includes a noise detection module 100 and a heat dissipation control module 200.

[0032] The noise detection module 100 and the heat dissipation control module 200 are communicatively connected. That is, the noise detection module 100 can send the detected data to the heat dissipation control module 200. The specific implementation method is not limited in this application.

[0033] The noise detection module 100 is used to detect the ambient noise of the environment where the equipment is located and the fan noise generated by the cooling fan, and send the ambient noise and the fan noise to the heat dissipation control module 200.

[0034] The cooling fan is installed in the device and is used to dissipate heat from the device, which may be a VR device, smart glasses, etc.

[0035] The heat dissipation control module 200 is used to adjust the speed of the cooling fan based on the ambient noise and the fan noise detected by the noise detection module 100.

[0036] Specifically, the principle by which the heat dissipation control module 200 adjusts the speed of the cooling fan in the device based on the ambient noise and fan noise detected by the noise detection module 100 is as follows:

[0037] When the user is using the VR device normally, the noise detection module 100 and the heat dissipation control module 200 work normally. The noise detection module 100 will collect the ambient noise of the VR device. Assuming the ambient noise threshold is Sh1 (which can be adjusted according to the actual situation), if the current ambient noise is greater than the set ambient noise threshold Sh1, then music may be playing or some other operations may be being performed externally. At this time, due to the large ambient noise, the user is not very able to perceive the fan noise compared to the noise generated by the cooling fan inside the VR device.

[0038] When the collected ambient noise is greater than the set ambient noise intensity threshold Sh1, the current fan speed will be obtained. If the current fan speed is the maximum speed Nmax, the current speed will be kept unchanged; if the current fan speed is less than the maximum speed, the fan speed will be increased to the maximum speed Nmax.

[0039] When the collected ambient noise is less than the set ambient noise intensity threshold Sh1, the VR device acquires fan noise intensity data collected near the fan, assuming the fan noise intensity threshold is Sh2 (which can be set according to actual needs). When the acquired fan noise intensity is less than the threshold Sh2, the current fan speed remains unchanged; when the acquired fan noise intensity is greater than the threshold Sh2, the current fan speed is reduced to decrease fan noise. In other words, when ambient noise is low, users are more sensitive to fan noise; when fan noise exceeds the threshold, the current fan speed is reduced to decrease fan noise and improve the user experience.

[0040] In some embodiments of this application, such as Figure 2 As shown, the noise detection module 100 includes a first noise detection unit 110 and a second noise detection unit 120. Specifically, the first noise detection unit 110 and the second noise detection unit 120 can be microphones.

[0041] The first noise detection unit 110 is disposed on the outer surface of the device and is used to detect the ambient noise of the environment in which the device is located. There can be multiple first noise detection units, and multiple first noise detection units 110 are evenly distributed on the outer surface of the device. For example, three microphones are evenly distributed on the outer surface of the VR device to collect the ambient noise of the environment in which the VR device is located.

[0042] The second noise detection unit 120 is located inside the device and close to the cooling fan, and is used to detect the fan noise generated by the cooling fan.

[0043] In some embodiments of this application, such as Figure 2 As shown, the heat dissipation control module 200 includes: a microprocessor 210 and a heat dissipation control unit 220;

[0044] The microprocessor 210 is used to generate a fan control signal based on the ambient noise and the fan noise, and send the fan control signal to the heat dissipation control unit 210; specifically, the microprocessor 210 can be composed of a microprocessor such as a single-chip microcomputer.

[0045] The heat dissipation control unit 210 is used to adjust the speed of the cooling fan according to the fan control signal.

[0046] Specifically, Figure 2 The principle by which the heat dissipation adjustment device adjusts the speed of the cooling fan in the equipment is as follows: Figure 3 As shown:

[0047] When a user is using the VR device normally, the cooling fan and microphone will work normally. The microphone of the first noise detection unit 110 located on the outer surface of the VR device will collect ambient noise. Assuming the ambient noise threshold is Sh1 (which can be adjusted according to the actual situation), if the current ambient noise is greater than the set ambient noise threshold Sh1, then music may be playing or some other operations may be taking place outside. At this time, due to the large ambient noise, the user is not very able to perceive the fan noise compared to the noise generated by the cooling fan rotating inside the VR device.

[0048] When the microprocessor 210 obtains that the ambient noise collected by the microphone of the first noise detection unit 110 on the outer surface of the VR device is greater than the set ambient noise intensity threshold Sh1, it will obtain the current fan speed. If the current fan speed is the maximum speed Nmax, then the current speed will remain unchanged; if the current fan speed is less than the maximum speed, then the fan speed will be increased to the maximum speed Nmax.

[0049] When the microprocessor 210 detects that the ambient noise collected by the microphone of the first noise detection unit 110 on the outer surface of the VR device is less than the set ambient noise intensity threshold Sh1, it will acquire the fan noise intensity data collected by the microphone of the second noise detection unit 120 near the fan inside the VR device, assuming the fan noise intensity threshold is Sh2 (which can be set according to actual needs). When the noise intensity acquired by the second noise detection unit 120 is less than the fan noise intensity threshold Sh2, the current fan speed remains unchanged; when the noise intensity acquired by the second noise detection unit 120 is greater than the fan noise intensity threshold Sh2, the current fan speed is reduced to decrease fan noise.

[0050] The device heat dissipation adjustment device provided in this embodiment includes: a noise detection module and a heat dissipation control module; the noise detection module and the heat dissipation control module are communicatively connected; the noise detection module detects the ambient noise of the environment in which the device is located and the fan noise generated by the cooling fan, and sends the ambient noise and the fan noise to the heat dissipation control module; the cooling fan is installed in the device to dissipate heat from the device; the heat dissipation control module adjusts the speed of the cooling fan according to the ambient noise and the fan noise. Compared with the prior art, the device heat dissipation adjustment device of this application can adjust the speed of the cooling fan according to the ambient noise of the device and the fan noise generated by the cooling fan, thereby achieving a balance between user experience and heat dissipation noise by dynamically adjusting the speed of the cooling fan, thus providing users with a better experience.

[0051] like Figure 4As shown in the illustration, this application also provides a VR device, including a cooling fan and the device heat dissipation adjustment device 10 described in the above embodiments. The cooling fan is disposed in the VR device and is used to dissipate heat from the VR device, and the device heat dissipation adjustment device is used to adjust the speed of the cooling fan.

[0052] Specifically, the device heat dissipation adjustment device of this application can adjust the speed of the cooling fan according to the ambient noise of the VR device and the fan noise generated by the cooling fan. By dynamically adjusting the speed of the cooling fan, the device can achieve a balance between user experience and heat dissipation noise, thereby enabling users to obtain a better experience.
