Abstract
Description
Technical Field
[0001] The utility model relates to the field of laser radar, and in particular to a laser radar. Background Art
[0002] LiDAR is a high-precision, high-resolution sensor, but due to the particularity of its working principle, it generates heat and needs to be dissipated.
[0003] At present, there are several main ways to dissipate heat for LiDAR: cooling fan, a fan is set inside or outside the LiDAR to cool the heat sink by air to reduce the temperature of the LiDAR. Heat pipe heat dissipation, through the working principle of the heat pipe, the heat inside the LiDAR is transferred to the heat sink, and then the temperature is reduced by cooling the heat sink by air. Liquid cooling heat dissipation, a water cooling system is set inside the LiDAR to reduce the temperature of the LiDAR through water circulation. Peltier element heat dissipation, through the working principle of the Peltier element, heat is transferred from one panel to another to achieve a cooling effect. However, the above-mentioned heat dissipation methods are not conducive to the miniaturization design of LiDAR, and are relatively expensive.
[0004] Another way to dissipate heat is to set up thermal conductive structures such as thermal conductive gel, thermal conductive silicone grease or thermal conductive pad to conduct heat to the shell. This method is low-cost and has little effect on the volume of the laser radar. However, the inventors found that when thermal conductive gel, thermal conductive silicone grease or thermal conductive pad are installed by bonding or other means, the bonding strength of these thermal conductive structures deteriorates and debris easily falls off when they are used for a long time and work under mechanical shock conditions such as vibration, which will cause abnormal noise in the radar, reduce NVH performance, block the effective optical aperture of the optical parts, and many other problems, affecting the normal use of the laser radar.

[0045] Example
[0046] The inventors have discovered that when a heat-conducting structure is used for a long time and is subjected to mechanical shock conditions such as vibration, the bonding strength of the heat-conducting structure deteriorates and debris easily falls off, causing abnormal noise in the radar, reduced NVH performance, and obstruction of the effective optical aperture of the optical components, among other problems, thus affecting the normal use of the laser radar 100.
[0047] Please refer to Figure 1 This embodiment provides a laser radar 100, which can prevent the laser radar 100 from being affected by heat-conducting structure debris, thereby increasing the service life of the laser radar 100.
[0048] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, the laser radar 100 includes a first shell 110, a second shell 130, a transceiver module 150 and a heat conductor 170. The first shell 110 is installed on the second shell 130 and encloses a mounting cavity 120. The transceiver module 150 is installed in the mounting cavity 120. The transceiver module 150 is provided with a first mounting structure 151, and the first shell 110 is provided with a second mounting structure 111. Among them, one of the first mounting structure 151 and the second mounting structure 111 is a groove, and the other is a boss. The heat conductor 170 is installed in the groove and abuts against the boss to limit the heat conductor 170 in the groove.
[0049] In this embodiment, a first mounting structure 151 is provided on the transceiver module 150, and a second mounting structure 111 is provided on the first shell 110. One of the first mounting structure 151 and the second mounting structure 111 is set as a groove, and the other is set as a boss. The heat conductor 170 is installed in the groove and abuts against the boss to confine the heat conductor 170 in the groove, so that the heat on the transceiver module 150 can be conducted to the first shell 110 through the heat conductor 170, and then dissipated through the first shell 110. The heat conductor 170 is confined in the groove, which can reduce mechanical vibration. Most importantly, even if the heat conductor 170 has a reduced bonding force and chips fall off, the chips will be confined in the groove, and the installation cavity will not be formed, thereby preventing the chips from affecting the normal use of the laser radar 100.
[0050] It should be noted that in some embodiments of the present application, one of the first housing 110 and the second housing 130 is an upper housing and the other is a lower housing, and the lower housing is generally mounted on the vehicle frame. The heat of the upper housing can be directly radiated into the air, while the heat of the lower housing is transferred to the vehicle body through the mechanical interface between the radar and the vehicle body, and heat is dissipated through the vehicle body.
[0051] In this embodiment, the first housing 110 is an upper housing, and the second housing 130 is a lower housing. The upper housing and the lower housing are assembled together by means of buckles or screws.
[0052] The operating temperature of the laser radar 100 is -40~+85℃, and the storage temperature is -40~+105℃. The components of the whole machine need to meet this working condition, so it is necessary to actively dissipate heat for high-heat consumption components to ensure normal operation under high-temperature conditions. The transceiver module and the main control circuit board 190, as the most important high-heat consumption components of the laser radar 100, need to set corresponding heat conduction paths to achieve heat conduction.
[0053] It should also be noted that the transceiver module 150 is the most important optical module in the laser radar 100, which is an integration of the transmitting module 153 and the receiving module 155. The transmitting module 153 is used to emit light beams outward, and the receiving module 155 is used to receive echoes from obstacles.
[0054] In this embodiment, the heat conduction path is: the transmitting module 153 and the receiving module 155 can conduct part of the heat to the upper housing and the other part of the heat to the lower housing. The heat of the main control circuit board 190 is conducted to the lower housing. The upper housing and the lower housing then radiate the heat into the air or transfer it to the frame to achieve heat dissipation.
[0055] Please refer to Figure 1-Figure 8 Specifically, the transceiver module 150 includes a mounting seat 152, a transmitting module 153 and a receiving module 155. The transmitting module 153 and the receiving module 155 are both mounted on the mounting seat 152, and the mounting seat 152 is mounted on the second shell 130. The first mounting structure 151 includes a first mounting groove 156, and the first mounting groove 156 is arranged on a side of the transmitting module 153 away from the mounting seat 152. The second mounting structure 111 includes a first heat-conducting boss 113. The first heat-conducting boss 113 is arranged at a position inside the first shell 110 corresponding to the first mounting groove 156. The heat-conducting member 170 includes a first heat-conducting structure 171. The first heat-conducting structure 171 is arranged in the first mounting groove 156, and the first heat-conducting boss abuts against the first heat-conducting structure 171, and the first heat-conducting structure 171 can be restricted in the first mounting groove 156.
[0056] In this embodiment, the first heat-conducting structure 171 is arranged by setting the first installation groove 156 on the top wall of the emission module 153, and the first heat-conducting boss 113 corresponding thereto is arranged on the first housing 110, so that the first heat-conducting structure 171 is confined in the first installation groove 156, and the heat of the emission module 153 can be conducted to the first heat-conducting boss 113 through the first heat-conducting structure 171, and then transferred to the first housing 110 by the first heat-conducting boss 113, and finally radiated into the air by the first housing 110. In this way, part of the heat of the emission module 153 is dissipated through the first object.
[0057] In this embodiment, the mounting seat 152 is provided with a second mounting groove 157 , and a second heat-conducting structure 173 is provided in the second mounting groove 157 . The bottom wall of the emission module 153 abuts against the second heat-conducting structure 173 , and the second heat-conducting structure 173 can be confined in the second mounting groove 157 .
[0058] The present application provides a second mounting groove 157 on the mounting seat 152, and provides a second heat-conducting structure 173 in the second mounting groove 157, so that after the transmitting module 153 is installed on the mounting seat 152, the second heat-conducting structure 173 will be restricted in the second mounting groove 157, thereby preventing its debris from affecting the laser radar 100. The second heat-conducting structure 173 can conduct part of the heat of the transmitting module 153 to the mounting seat 152, and then conduct it to the second housing 130 through the mounting seat 152, so that the heat dissipation of the transmitting module 153 can be better achieved.
[0059] In this embodiment, the receiving module 155 includes a lens holder 154, a binning block 158, a front shielding shell 159, a circuit board and a rear shielding shell 161. The front shielding shell 159 is mounted on the rear shielding shell 161, and the circuit board is mounted between the front shielding shell 159 and the rear shielding shell 161. The binning block 158 is mounted on the front shielding shell 159, and the lens holder 154 is mounted on the binning block 158 and mounted on the mounting seat 152. The top wall of the binning block 158 is provided with a third mounting groove 163, and a third heat-conducting structure 174 is arranged in the third mounting groove 163. The first shell 110 is provided with a second heat-conducting boss 115 at a position corresponding to the third mounting groove 163, and the second heat-conducting boss 115 abuts against the third heat-conducting structure 174, and the third heat-conducting structure 174 can be restricted in the third mounting groove 163.
[0060] The present application sets a third mounting groove 163 on the top wall of the bin block 158, sets a third heat-conducting structure 174 in the third mounting groove 163, and sets a corresponding second heat-conducting boss 115 in the first shell 110, so that the third heat-conducting structure 174 is confined in the third mounting groove 163, and part of the heat of the bin block 158 can be led to the first shell 110 through the third heat-conducting structure 174.
[0061] Of course, in some embodiments of the present application, a mounting groove may be provided on the bottom wall of the bin block 158, and a heat-conducting structure may be provided in the groove. The bottom wall of the bin block 158 is fitted with the mounting structure to confine the heat-conducting structure within the mounting groove, so that a portion of the heat of the bin block 158 is transferred to the mounting seat 152 through the heat-conducting structure, and then transferred to the second shell 130 through the mounting seat 152.
[0062] Please refer to Figure 1-Figure 8In this embodiment, a graphene heat conductive sheet 175 is provided on the outer periphery of the rear shielding shell 161. Since the rear shielding shell 161 is generally far away from the first shell 110 and the second shell 130, heat conduction cannot be achieved. In this embodiment, by providing the graphene heat conductive sheet 175, it can radiate heat into the installation cavity, thereby achieving heat dissipation.
[0063] In this embodiment, a fourth mounting groove 165 is provided at a position corresponding to the mounting seat 152 and the lens seat 154, and a fourth heat-conducting structure 176 is provided in the fourth mounting groove 165. The bottom wall of the lens seat 154 abuts against the fourth heat-conducting structure 176, and the lens seat 154 can confine the fourth heat-conducting structure 176 within the fourth mounting groove 165.
[0064] In this embodiment, the fourth mounting groove 165 and the fourth heat-conducting structure 176 are provided so that the heat of the lens holder 154 can pass through the fourth heat-conducting structure 176 to the mounting seat 152 and finally pass through the mounting seat 152 to the second housing 130 .
[0065] Of course, in this embodiment, the top wall of the lens holder 154 is also provided with a mounting groove, and a heat-conducting structure is also provided in the mounting groove. The heat-conducting structure is confined in the mounting groove by the first shell 110, so that part of the heat of the lens holder 154 is conducted to the first shell 110.
[0066] Secondly, in some embodiments of the present application, the mounting seat 152 and the lens seat 154 can also be integrally formed to form a mounting and heat-conducting carrier for the transmitting module 153 and the receiving module 155, so that heat can be conducted from the whole formed by the mounting seat 152 and the lens seat 154 to the second shell 130.
[0067] Please refer to Figure 1-Figure 8 In this embodiment, a mounting boss 131 is provided on the inner side of the second housing 130, and a mounting portion 164 is provided on the mounting seat 152, and the mounting portion 164 abuts against the mounting boss 131 and is connected to each other. The mounting portion 164 abuts against the mounting boss 131, so that the heat of the mounting seat 152 can be led to the second housing 130 through the mounting boss 131.
[0068] In this embodiment, the laser radar 100 further includes a fixing screw 180 , the mounting seat 152 is made of metal, and fixing holes are provided on the mounting boss 131 and the mounting portion 164 , and the fixing screw 180 is passed through the fixing hole.
[0069] Since the mounting seat 152 made of metal has a good heat conduction effect and is connected to the mounting boss 131 via screws, the screws can also achieve better heat conduction.
[0070] In this embodiment, the laser radar 100 further includes a main control circuit board 190 , which is mounted on the second housing 130 and is located below the mounting seat 152 ;
[0071] The second housing 130 is provided with a third heat-conducting boss 133 , and the third heat-conducting boss 133 is provided with a heat-conducting pad 177 . The heat-conducting pad 177 abuts against the heat-generating components on the main control circuit board 190 .
[0072] In this embodiment, the heat on the main control circuit board 190 can be transferred to the second housing 130 by providing the heat conductive pad 177 .
[0073] Of course, in this embodiment, a mounting groove can be set on the third heat-conducting boss 133, and the thermal pad 177 can be set in the mounting groove. The electrical components on the main control board circuit board can abut against the thermal pad 177 for heat conduction and the thermal pad 177 can also be confined in the mounting groove.
[0074] Please refer to Figure 1-Figure 8 In this embodiment, heat dissipation fins are provided on the first housing 110. The heat dissipation fins can allow the first housing 110 to radiate heat into the air better.
[0075] It should be noted that, in the present embodiment, the heat conducting member 170, the heat conducting structure, the first heat conducting structure 171, the second heat conducting structure 173, and the third heat conducting structure 174 can be one of thermal grease, thermal gel, and thermal pad 177, or other types of thermally conductive filling materials. These thermally conductive materials are filled in the first mounting groove 156, the second mounting groove 157, and other mounting grooves, which are equivalent to a sealed environment and are compressed, and will not overflow due to long-term work. Secondly, considering the tolerance, based on the assembly relationship and manufacturing tolerance, some scenes cannot be completely sealed, but the control of the gap also needs to be within the safety gap, thereby greatly reducing the probability of overflow.
[0076] It should also be noted that in order to effectively reduce the contact thermal resistance, the thermally conductive metal contact surface is generally specially treated and has a higher surface finish than the non-thermal conductive surface.
[0077] In summary, the working principle and beneficial effects of the laser radar 100 provided by the embodiment of the utility model include:
[0078] In this embodiment, a first mounting structure 151 is provided on the transceiver module 150, and a second mounting structure 111 is provided on the first shell 110. One of the first mounting structure 151 and the second mounting structure 111 is set as a groove, and the other is set as a boss. The heat conductor 170 is installed in the groove and abuts against the boss to confine the heat conductor 170 in the groove, so that the heat on the transceiver module 150 can be conducted to the first shell 110 through the heat conductor 170, and then the heat is dissipated through the first shell 110. The heat conductor 170 is confined in the groove, which can reduce mechanical vibration. Most importantly, even if the heat conductor 170 has a reduced bonding force and chips fall off, the chips and blocks of heat-conducting material will be confined in the groove, and the installation cavity 120 will not be carried out, thereby preventing the chips from affecting the normal use of the laser radar 100.
[0079] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
