[0060] In the embodiment, the clamping assembly further comprises a power end 2 and a supporting device, the light source assembly 1 is arranged on the supporting device, the second heat-conducting part is arranged on the outer surface of the supporting device, the supporting device is used for mounting the external shooting device 3, and the power end 2 is rotationally connected to the supporting device and used for driving the supporting device to rotate and synchronously driving the light source assembly 1 to rotate, so that the light compensation direction of the light source assembly 1 is consistent with the shooting direction of the external shooting device 3.

[0061] In other embodiments, the light source assembly 1 can also be arranged on the power end 2.

[0062] Specifically, the external shooting device 3 includes a mobile phone, a camera or a tablet computer or other electronic devices with a shooting function. The power end 2 includes a motor, the motor includes a motor shaft 4, a motor stator 5 and a handle 6, the motor shaft 4 is rotationally connected to the supporting device, the motor stator 5 is arranged on the periphery of the motor shaft 4, and the handle 6 is connected to the motor stator 5. A user can hold the handle 6 to drive the supporting device to rotate through the motor shaft 4, so that the light compensation direction of the light source assembly 1 is consistent with the shooting direction of the external shooting device 3, and the stability of the supporting device is ensured.

[0063] The power end 2 is rotationally connected to the supporting device and used for driving the supporting device to rotate and synchronously driving the light source assembly 1 to rotate, so that the light compensation direction of the light source assembly 1 is consistent with the shooting direction of the external shooting device 3, so as to ensure that the light emitted by the light source assembly 1 can accurately illuminate the object to be shot, and the shooting effect, shooting efficiency and image quality are ensured.

[0064] In the embodiment, the supporting device includes a supporting arm 7 and a base 8, the power end 2 is rotationally connected to the supporting arm 7, the supporting arm 7 is connected to the base 8, the light source assembly 1 is arranged on the supporting arm 7, and the second heat-conducting part is arranged on the side of the supporting arm 7 in surface contact with the first heat-conducting part, or the light source assembly 1 is arranged on the base 8, and the second heat-conducting part is arranged on the side of the base 8 in surface contact with the first heat-conducting part. It should be noted that the light source assembly 1 arranged on the supporting arm 7 or arranged on the base 8 is consistent with the shooting direction of the external shooting device 3. Preferably, in the embodiment, the light source assembly 1 is preferably arranged on the supporting arm 7.

[0065] The supporting arm 7 can be integrally made of the second heat-conducting part, so that the heat dissipation area is greatly increased.

[0066] Specifically, the base 8 comprises a quick-mounting plate seat 9 and a quick-mounting plate 10, the quick-mounting plate 10 is installed on the quick-mounting plate seat 9, and the external shooting device 3 is installed on the quick-mounting plate 10.

[0067] In the embodiment, the first heat-conducting part and the second heat-conducting part are made of metal or heat-conducting resin.

[0068] Specifically, the metal includes aluminum alloy, magnesium alloy, stainless steel, copper, titanium, silver or gold, and the heat-conducting resin includes heat-conducting plastic, heat-conducting silica gel or graphite-doped plastic. The first heat-conducting part and the second heat-conducting part can be made of the same material or different materials. In the embodiment, the first heat-conducting part and the second heat-conducting part are made of aluminum alloy. In other embodiments, the first heat-conducting part can be made of heat-conducting plastic, and the second heat-conducting part can be made of magnesium alloy; or the first heat-conducting part is made of stainless steel, and the second heat-conducting part is made of graphite-doped plastic.

[0069] In the prior art, the shell of the light source assembly 1 is generally made of all-plastic material, and the structure in contact with the light source assembly 1 is also plastic. The thermal conductivity coefficient of plastic is only 0.17-0.5 W / mK, which cannot achieve the effect of heat conduction, resulting in poor heat dissipation effect of the device, and the power of the light source assembly 1 is also limited, which makes the light compensation effect of the light source assembly 1 poor, and the effect of the photographed photos is also poor.

[0070] In the embodiment, the thermal conductivity coefficient of aluminum alloy is 155-226 W / mK, the thermal conductivity coefficient of magnesium-zinc alloy reaches 100 W / mK, the thermal conductivity coefficient of stainless steel is 15-18 W / mK, the thermal conductivity coefficient of copper is 377 W / mK, the thermal conductivity coefficient of titanium is 15.24 W / mK, the thermal conductivity coefficient of silver is 412 W / mK, and the thermal conductivity coefficient of gold is 317 W / mK. The thermal conductivity coefficient of heat-conducting silica gel is 200 W / mK. Through the arrangement of the first heat-conducting part and the second heat-conducting part in the embodiment, the heat generated by the light source assembly 1 can be conducted to the clamping assembly and dissipated from the clamping assembly, which greatly improves the heat dissipation efficiency of the light source assembly 1 and increases the power of the light source assembly 1, so that the clamping mechanism can be applied to a light source assembly 1 with higher power and stronger illumination, thereby ensuring the light compensation effect of the external shooting device 3 during shooting and the effect of the photographed photos or videos, and prolonging the service life of the light source assembly.

[0071] Specifically, the light source assembly 1 comprises LED lamp beads 101, a circuit board (not shown in the figure) and a shell 102, the LED lamp beads 101 are arranged at the front end of the shell 102, and the circuit board is electrically connected to the LED lamp beads 101. In the embodiment, the shell 102 is made of the first heat-conducting part, and the shell 102 as a whole provides good heat conduction performance.

[0072] In other embodiments, the shell 102 is composed of a first heat-conducting part and a shell assembly, the first heat-conducting part being arranged at the region of the shell 102 directly contacting the clamping assembly. With the shell 102 composed of parts, on the basis of meeting the basic requirement of heat conduction, different shell assemblies can be selected according to different actual situations. For example, in order to save material cost, the shell assembly can be made of common engineering plastic with low cost; or in order to achieve the effect of partial light transmission, the shell assembly can be made of plastic products with light-transmitting material.

[0073] When the LED lamp is working, it will emit a very high heat. Specifically, the reason why the LED lamp generates heat is that the added electric energy is not all converted into light energy, but a part is converted into heat energy. The light efficiency of the LED lamp is currently only 100 lm / W, and the electric-light conversion efficiency is about 20-30%. That is, about 70% of the electric energy becomes heat energy. Specifically, the generation of the junction temperature of the LED lamp is caused by two factors: one is that the internal quantum efficiency is not high, that is, when the electron and hole are combined, not all of them can produce photons, which is usually called that the recombination rate of the PN region current carriers is reduced due to the "current leakage". The leakage current multiplied by the voltage is the power of this part, that is, converted into heat energy, but this part does not account for the main component, because the internal photon efficiency is close to 90% now. The second is that the internal generated photons cannot all be emitted outside the chip and finally converted into heat, which is the main part, because the external quantum efficiency is only about 30% at present, and most of them are converted into heat. A good heat conduction and heat dissipation system is necessary to ensure the service life of the LED lamp and slow down the light decay.

[0074] By arranging the first heat-conducting part in the shell 102, the heat of the LED lamp beads 101 can be quickly conducted to the clamping assembly and conducted out of the clamping assembly, so that the heat dissipation is more smooth, the heat dissipation efficiency of the light source assembly 1 is enhanced, the illumination of the light source assembly 1 is ensured, and the service life of the light source assembly 1 is prolonged.

[0075] In order to improve the heat dissipation performance, the shell 102 is filled with a heat-conducting filler (not shown in the figure), which is used to conduct the heat energy generated by the LED lamp beads 101. The arrangement of the heat-conducting filler is beneficial to the heat dissipation of the light source assembly 1, increases the power of the light source assembly 1, enhances the light supplementing efficiency of the light source assembly 1, and ensures the light supplementing effect of the light source assembly 1.

[0076] In this embodiment, a counterweight cross beam 11 is further included, the counterweight cross beam 11 being arranged on the support arm 7, and a slide rail 12 being arranged on the side wall of the counterweight cross beam 11 and being matched with the support arm 7, the slide rail 12 being used to move the support arm 7 relative to the counterweight cross beam 11 and synchronously drive the power end 2 to move relative to the counterweight beam.

[0077] Preferably, the counterweight crossbeam 11 is arranged to play the role of counterweight, ensuring the balance of the clamping mechanism, and further ensuring the shooting effect of the external shooting device 3 mounted on the clamping mechanism.

[0078] In this embodiment, the counterweight crossbeam 11 is integrally formed with the shell 102, and the counterweight crossbeam 11 comprises a hollow cavity 111, and the circuit board is arranged in the shell 102 or in the cavity 111.

[0079] In this embodiment, the clamping assembly further comprises an adjusting member 13 and a clamping member (not shown in the figure), the clamping member is arranged on the support arm 7, and the adjusting member 13 is rotatably arranged on the support arm 7, used to contact the clamping member to fix the counterweight crossbeam 11 on the support arm 7, and used to not contact the clamping member to enable the support arm 7 to move relative to the counterweight crossbeam 11.

[0080] Specifically, when the adjusting member 13 is actuated to contact the clamping member, the counterweight crossbeam 11 is fixed in the support arm 7 and the support arm 7 cannot move relative to the counterweight crossbeam 11. When the adjusting member 13 is actuated to disengage the clamping member, the support arm 7 can move relative to the counterweight crossbeam 11, synchronously driving the base 8 and the power end 2 to move relative to the counterweight crossbeam 11, so that the user can adjust the center of gravity of the clamping mechanism. After the user adjusts the center of gravity, the adjusting member 13 can be actuated to contact the clamping member, so that the counterweight crossbeam 11 is fixed in the support arm 7. The adjusting member 13 is preferably a lever.

[0081] In this embodiment, the clamping assembly further comprises a rotating table 14, and the rotating table 14 is arranged on the support device, and the power end 2 is rotatably connected to the support device through the rotating table 14.

[0082] Specifically, the motor shaft 4 is connected to the rotating table 14 in a matched manner, and the motor shaft 4 drives the rotating table 14 to rotate, synchronously driving the support device to rotate.

[0083] In order to enhance the heat conduction performance, other structural components in contact with the support arm, such as the power end 2 and the counterweight crossbeam 11, can be made of the second heat-conducting part.

[0084] A gimbal device comprising the clamping mechanism of any one of the above. Specifically, the gimbal device comprises a circuit control module (not shown in the figure), and the circuit control module is electrically connected to the light source assembly 1 and the clamping assembly. Specifically, the circuit control module is preferably integrated on the circuit board, without the need to additionally arrange a separate circuit control module, further saving the space of the whole gimbal device.

[0085] Compared with the prior art, the clamping assembly, the clamping mechanism and the holder device provided by the embodiment can utilize the large-area structure on the clamping assembly through the surface contact between the light source assembly 1 and the clamping assembly, and can conduct the heat energy generated by the light source assembly to the clamping assembly through the first heat conduction part and the second heat conduction part, and dissipate the heat energy from the clamping assembly, so as to improve the heat dissipation efficiency of the light source assembly 1, increase the power of the light source assembly 1, make the clamping mechanism applicable to a light source assembly 1 with higher power, and have stronger light, so as to ensure the light compensation effect of the external shooting device during shooting and the photo or video effect of the shot photos or videos, and prolong the service life of the light source assembly.

[0086] The power end 2 is rotationally connected to the support device, and is used to drive the support device to rotate, and simultaneously drive the light source assembly 1 to rotate synchronously, so that the light compensation direction of the light source assembly 1 is consistent with the shooting direction of the external shooting device, so as to ensure that the light emitted by the light source assembly 1 can be accurately irradiated to the object to be shot, and ensure the shooting effect, shooting efficiency and photo quality.

[0087] The shell 102 is filled with a heat-conducting filler inside, and the heat-conducting filler is used to conduct the heat energy generated by the LED lamp bead 101. The heat-conducting filler is beneficial to heat dissipation of the light source assembly, increases the power of the light source assembly, and strengthens the light compensation efficiency of the light source assembly, so as to ensure the light compensation effect of the light source assembly.

[0088] In order to improve the heat dissipation effect, the cavity 111 can also be filled with a heat-conducting filler.

The counterweight cross beam 11 can play a role of counterweight, so as to ensure the balance of the clamping mechanism, and further ensure the shooting effect of the external shooting device installed on the clamping mechanism.

[0105] Specifically, the first magnetic attraction assembly 101 and the second magnetic attraction assembly 102 are both magnets; or the first magnetic attraction assembly 101 is a magnet, and the second magnetic attraction assembly 102 is a ferromagnetic metal piece; or the second magnetic attraction assembly 102 is a magnet, and the first magnetic attraction assembly 101 is a ferromagnetic metal piece, and the first magnetic attraction assembly and the second magnetic attraction assembly can be attracted to each other.

[0106] Meanwhile, the first magnetic attraction assembly 101 and the second magnetic attraction assembly 102 have conductivity and can conduct electricity as a live wire.

[0107] In the embodiment, the first clamping arm 21 and the second clamping arm 22 are respectively connected with the bottom plate 20, and the bottom plate 20 is connected with the transmission arm 24, so that the components are connected with each other to form a heat conduction channel. The light source assembly 1 arranged at any position can conduct the generated heat energy, thereby improving the heat dissipation performance.

[0108] In addition, the inside of the bottom plate 20, the first clamping arm 21, the second clamping arm 22 or the transmission arm 24 can be provided with a large number of structural ribs and heat dissipation holes to increase the heat conduction area and enhance the heat dissipation condition.

[0109] The other features of the embodiment are the same as those of the embodiment 1, and will not be described herein.

[0110] The clamping mechanism obtained in the embodiment 1 is tested in a thermostat, and the temperature rise of the LED lamp bead 101 and the surrounding points is collected and tested. 3609 temperature quantities are collected to form a temperature rise curve. The test environment temperature is 30℃, the LED lamp bead 101 works at a power of 6W, a point temperature instrument is used to collect the temperature, and the collection time is 1 hour.

[0111] As Figure 6It can be seen from the figure that the a, b, c and d four temperature rising curves are fast rising temperature trend in the early stage, and are relatively flat temperature change trend in the middle and later stage. Within 1 hour, the highest temperature of the a curve is 50.2℃, the highest temperature of the b curve is 43℃, the highest temperature of the c curve is 39.3℃, and the highest temperature of the d curve is 38.1℃. The difference between the highest temperature of the a curve and the highest temperature of the b curve, c curve and d curve is controlled within more than 10 degrees, and the temperature difference between the temperature of the a curve and the temperature of the b curve, c curve and d curve is also controlled within 20 degrees. It can be concluded that the counterweight cross beam 11, the support arm 7 and the power end 2 can well conduct heat at the temperature of the LED lamp bead 101, conduct the temperature at the LED lamp bead 101, realize the heat dissipation of the light source assembly 1, and improve the heat dissipation efficiency of the light source assembly 1.

[0112] The LED lamp bead 101 in the above test is subjected to aging test, and the aging test is 6 hours. The test results are shown in Table 1:

[0113] Table 1:

[0114]

[0115] From the aging test results of the LED lamp bead 101 in Table 1, it can be concluded that:

[0116] Under high power and long duration, the lamp bead is not damaged. The present scheme can realize the heat dissipation of the LED lamp bead 101, realize the heat dissipation of the light source assembly 1, improve the heat dissipation efficiency of the light source assembly 1, and also ensure the service life of the light source assembly 1.

[0117] The LED lamp bead 101 in the above test is taken out alone for independent temperature test. 1106 temperature quantities are collected to form a temperature rising curve. The test environment temperature is 30℃, the LED lamp bead 101 works at 6W power, a point temperature instrument is used to collect the temperature, and the collection time is 1 hour. The test results are shown in Figure 7As shown, the e curve in the figure is the temperature change trend of the back of the LED lamp bead 101, and the f curve is the temperature change trend of the side of the LED lamp bead 101. As can be seen from the figure, the temperature rise curves of e and f are both rapidly rising in the early stage, and are both relatively flat in the middle stage, and are both rapidly falling in the late stage. Within 1 hour, the highest temperature of the e curve is 83.2°C, and the highest temperature of the f curve is 76.3°C. After working for 1 hour, only the power can be turned off, and the LED lamp bead 101 is naturally cooled. Therefore, it can be concluded that the heat dissipation effect of the LED lamp bead 101 is very poor when it works alone, and the temperature cannot be reduced, which can easily burn the device and cause short circuit and damage to the equipment.

[0118] According to the test results, the heat dissipation effect of the LED lamp bead 101 is good by using the scheme of the embodiment, and the heat dissipation temperature difference reaches 45.1°C. By using the scheme, a good heat dissipation environment can be provided for the LED lamp bead 101, and the lamp bead is prevented from being damaged due to overheating. Therefore, an LED lamp bead 101 with a much larger power than the existing conventional product can be selected, and the light supplementing performance is greatly enhanced. The performance of the LED lamp bead 101 using the scheme is greatly improved, the heat energy generated by the light source assembly 1 can be quickly conducted to the clamping assembly, and dissipated from the clamping assembly, so as to improve the heat dissipation efficiency of the light source assembly 1, increase the power of the light source assembly 1, make the clamping mechanism applicable to a light source assembly 1 with a higher power, have stronger light, ensure the light supplementing effect of the external shooting device 3 when shooting and the photo or video effect of the shot photo or video, and prolong the service life of the light source assembly.
