[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] As the core component of the robot, the robot main control board is responsible for processing and controlling various actions and instructions of the robot. However, during the movement or operation of the robot, the main control board may be subjected to vibration and impact from the external environment, which may damage the main control board or affect its normal operation.

[0040] Currently, it is common to set a special main control board vibration reduction protection device in the robot. However, the existing main control board vibration reduction protection device can often only reduce the vibration received at a certain position, and cannot cope with vibrations in a wider range, resulting in poor vibration reduction effect.

[0041] The invention provides a main control board protection device.

[0042] Please refer to Figure n. In one embodiment of the present invention, the main control board protection device includes a support frame 100, an installation frame 200 and a vibration reduction structure 300. The support frame 100 is provided with a support groove 140; the installation frame 200 is located in the support groove 140, and the installation frame 200 is provided with a mounting groove 210 for mounting and fixing the main control board; the vibration reduction structure 300 is arranged between the support frame 100 and the installation frame 200, and the vibration reduction structure 300 includes a first vibration reduction component 400 and a second vibration reduction component 500 arranged at intervals along the depth direction of the mounting groove 210.

[0043] Specifically, the support frame 100 is provided with a support groove 140, the mounting frame 200 is provided with a mounting groove 210, the mounting frame 200 is arranged in the support groove 140, and the main control board is arranged in the mounting groove 210. It can be understood that the main control board is generally square or rectangular in shape, and correspondingly, the support frame 100 and the mounting frame 200 are also square or rectangular in shape, that is, the support groove 140 and the mounting groove 210 are also consistent with the shape of the main control board, so as to provide a relatively balanced vibration reduction effect in the circumferential direction of the main control board.

[0044] At the same time, a vibration reduction structure 300 is provided between the support frame 100 and the installation frame 200. The vibration reduction structure 300 is used to reduce the vibration transmitted from the support frame 100 to the installation frame 200, and also provides a connection between the installation frame 200 and the support frame 100. It can be understood that under the action of external force, the support frame 100 will inevitably be vibrated, and the vibration will be transmitted inward to the installation frame 200. The setting of the vibration reduction structure 300 reduces the vibration transmitted to the installation frame 200, thereby reducing the vibration transmitted to the main control board, and reducing the impact of the vibration on the main control board.

[0045] In the present invention, the vibration reduction structure 300 includes a first vibration reduction assembly 400 and a second vibration reduction assembly 500 which are arranged at intervals along the depth direction of the mounting groove 210. It can be understood that, for the convenience of explanation, the first vibration reduction assembly 400 is arranged at the first position and the second vibration reduction assembly 500 is arranged at the second position along the depth direction of the mounting groove 210. In this way, in the depth direction of the mounting groove 210, the first vibration reduction assembly 400 can perform vibration reduction processing on the vibration at the first position and the vicinity of the first position, and the second vibration reduction assembly 500 can perform vibration reduction processing on the vibration at the second position and the vicinity of the second position. In this way, by setting the first vibration reduction assembly 400 and the second vibration reduction assembly 500, the vibration at the first position and the vicinity of the second position can be better reduced, thereby improving the vibration reduction effect in the depth direction of the mounting groove 210.

[0046] In one embodiment, along the depth direction of the installation groove 210, the first vibration damping assembly 400 and the second vibration damping assembly 500 are arranged in an overlapping manner. That is, the connection line of the first vibration damping assembly 400 and the second vibration damping assembly 500 is parallel to the axis of the depth direction of the installation groove 210. However, the present design is not limited thereto. In another embodiment, along the depth direction of the installation groove 210, the first vibration damping assembly 400 and the second vibration damping assembly 500 are arranged in an staggered manner. That is, the extension line of the connection line of the first vibration damping assembly 400 and the second vibration damping assembly 500 intersects with the axis of the depth direction of the installation groove 210. In this way, the first vibration damping assembly 400 and the second vibration damping assembly 500 can also achieve the vibration damping effect at the first position and the second position.

[0047] Of course, in other embodiments, the vibration reduction structure 300 may further include a third vibration reduction component, and the first vibration reduction component 400, the second vibration reduction component 500 and the third vibration reduction component are arranged at intervals along the depth direction of the installation groove 210. Correspondingly, along the depth direction of the installation groove 210, the third vibration reduction component is arranged at a third position. The third vibration reduction component can perform vibration reduction processing on the vibration at the third position and the vicinity of the third position. The provision of the third vibration reduction component further improves the vibration reduction range of the vibration reduction structure 300, further improves the vibration reduction capacity of the vibration reduction structure 300, and further improves the vibration reduction effect of the main control board protection device. Here, there is no restriction on the number of vibration reduction components in the vibration reduction structure 300.

[0048] The technical solution of the present invention is to provide a support frame 100 having a support groove 140, a mounting frame 200 located in the support groove 140, and a vibration reduction structure 300 provided between the support frame 100 and the mounting frame 200 in the main control board protection device, wherein the mounting frame 200 is provided with a mounting groove 210 for mounting and fixing the main control board, and the vibration reduction structure 300 includes a first vibration reduction assembly 400 and a second vibration reduction assembly 500 arranged at intervals along the depth direction of the mounting groove 210. Thus, compared with the solution of only providing one vibration reduction assembly, the present invention can perform vibration reduction treatment on vibrations received by multiple positions of the main control board protection device by arranging the first vibration reduction assembly 400 and the second vibration reduction assembly 500 at intervals in the depth direction of the mounting groove 210, and at the same time, can also improve the vibration reduction capacity of the vibration reduction structure 300, thereby improving the vibration reduction range of the main control board protection device and improving the vibration reduction effect of the main control board protection device.

[0049] In an embodiment of the present invention, the first vibration damping assembly 400 includes a first fixed rod 410, a first slider 420, a first elastic member 430 and a first connecting rod 440. The first fixed rod 410 is fixed to the mounting frame 200, the first slider 420 can slide along the first fixed rod 410, the first elastic member 430 is arranged on the first fixed rod 410 and connected to the first slider 420, and the two ends of the first connecting rod 440 are respectively rotatably connected to the first slider 420 and the support frame 100.

[0050] Specifically, in the scheme shown in the figure of the present invention, one end of the first fixing rod 410 is fixed on the installation frame 200, and the other end is a free end. In one embodiment, the installation frame 200 is provided with a first fixing seat 220, the first fixing seat 220 is provided with a first fixing slot, and the first fixing seat 220 is also provided with a first fixing hole connected to the first fixing slot, and one end of the first fixing rod 410 is provided with a second fixing hole, the first fixing rod 410 extends into the first fixing slot, and the first fixing hole corresponds to the second fixing hole, and screws or bolts pass through the first fixing hole and the second fixing hole, so that the first fixing rod 410 is installed on the installation frame 200. In one embodiment, the end of the first fixing rod 410 extending into the first fixing slot is hollow, so that it is convenient to wear the screws or bolts and other structural parts, and it is also conducive to the lightweight of the first fixing rod 410. Of course, in other embodiments, the first fixing rod 410 and the installation frame 200 can also be connected by welding or other methods.

[0051] The first slider 420 is disposed on the first fixing rod 410, and the first slider 420 can slide along the length direction of the first fixing rod 410. At the same time, a first elastic member 430 is also installed on the first fixing rod 410, and one end of the first elastic member 430 is connected to the first slider 420. In this way, when the first slider 420 slides along the first fixing rod 410, the first elastic member 430 is deformed. In one embodiment, the first elastic member 430 can be configured as a spring, a spring sheet, etc., and the specific structure of the first elastic member 430 is not limited here.

[0052] One end of the first connecting rod 440 is rotatably connected to the first slider 420. In one embodiment, a through hole is provided at one end of the first connecting rod 440, and a through hole is also provided on the first slider 420. Connectors such as bolts pass through the two through holes in sequence, thereby connecting the first slider 420 and the first connecting rod 440, and allowing the first slider 420 and the first connecting rod 440 to rotate relative to each other. Of course, in other embodiments, the first slider 420 and the first connecting rod 440 can also achieve relative rotation through a universal joint.

[0053] The other end of the first connecting rod 440 is rotatably connected to the support frame 100. In one embodiment, the support frame 100 is provided with a first hinge seat 132, the first hinge seat 132 is provided with a through hole, and the other end of the first connecting rod 440 is also provided with a through hole, and bolts and other connecting members pass through the two through holes in sequence, thereby connecting the first connecting rod 440 and the support frame 100, and allowing the first connecting rod 440 and the support frame 100 to rotate relative to each other. Of course, in other embodiments, the first connecting rod 440 and the support frame 100 can also achieve relative rotation through a universal joint.

[0054] In this way, the installation frame 200, the first fixing rod 410, the first slider 420, the first connecting rod 440 and the support frame 100 are connected in sequence, thereby realizing a vibration-damping connection between the installation frame 200 and the support frame 100. When the support frame 100 is vibrated, the vibration is transmitted to the first slider 420 through the first connecting rod 440. Since the first connecting rod 440 is rotationally connected with the support frame 100 and the first slider 420, part of the vibration is absorbed; when the vibration is transmitted to the first slider 420, under the action of external force vibration, the first slider 420 will compress the first elastic member 430, causing the first elastic member 430 to deform, thereby absorbing part of the vibration; at the same time, as the first slider 420 slides, the first connecting rod 440 rotates relative to the first slider, thereby further absorbing part of the vibration. In this way, the external force vibration can be transmitted to the main control board after being absorbed and dispersed layer by layer, so that the vibration of the main control board is greatly reduced, thereby improving the vibration reduction effect of the main control board protection device and improving the protection of the main control board.

[0055] Of course, in other embodiments, the first vibration reduction assembly 400 may also be a spring with two ends respectively connected to the support frame 100 and the installation frame 200, which can also achieve a vibration reduction effect.

[0056] In an embodiment of the present invention, a first sliding groove 411 is provided in the first fixing rod 410, a first sliding block 420 is slidably provided in the first sliding groove 411, and a portion of the first sliding block 420 extends out of the first sliding groove 411 to be rotatably connected with the first connecting rod 440; a first elastic member 430 is respectively provided between the two sides of the first sliding block 420 and the two bottom walls of the first sliding groove 411.

[0057] Specifically, in the solution shown in the figure of the present invention, a first slide groove 411 for sliding the first slider 420 is further provided in the first fixed rod 410, and the first slide groove 411 is extended along the length direction of the first fixed rod 410. At the same time, a first opening 412 corresponding to the first slide groove 411 is also provided on the first fixed rod 410, and the first opening 412 is also a notch of the first slide groove 411. The first slider 420 is provided in the first slide groove 411, and at least part of the first slider 420 is exposed from the first opening 412, so as to facilitate the rotation connection between the first slider 420 and the first connecting rod 440. The provision of the first slide groove 411 provides a guide for the deformation of the first elastic member 430, and also provides a guide for the sliding of the first slider 420.

[0058] It can be understood that along the length direction of the first slide groove 411, the first slide groove 411 has two opposite groove bottom walls, and the first slider 420 is arranged between the two groove bottom walls of the first slide groove 411. A first elastic member 430 is respectively arranged between the two sides of the first slider 420 and the two groove bottom walls of the first slide groove 411, that is, a first elastic member 430 is respectively arranged on both sides of the first slider 420. In this way, when the first slider 420 slides under the action of an external force, the first slider 420 will compress one first elastic member 430, and the other first elastic member 430 will stretch. At this time, the deformation of the first elastic member 430 can absorb part of the vibration. As the first elastic member 430 continues to be compressed, when the first elastic member 430 is compressed to the limit, under the action of the deformation force of the first elastic member 430 itself, the first slider 420 will be driven to slide in the opposite direction, and the other first elastic member 430 will be compressed. When the other first elastic member 430 is compressed to the limit, the first slider 420 changes the sliding direction again. This is repeated so that the first slider 420 slides back and forth between the two first elastic members 430 to absorb vibration. At the same time, the two first elastic members 430 are arranged so that when the installation frame 200 vibrates, the two first elastic members 430 on both sides of the first slider 420 can offset each other and absorb vibration, which is conducive to keeping the first slider 420 in the initial position, so that the installation frame 200 can return to a stable state as soon as possible, which is conducive to keeping the main control board in a stable position and preventing the main control board from being displaced or damaged due to vibration.

[0059] It is worth noting that the first elastic member 430 is compressed to the limit, where compression to the limit may be the elastic limit of the first elastic member 430 itself, or the limit to which the first elastic member 430 can be compressed under the action of an external force. Similarly, the compression to the limit of the second elastic member 530 mentioned below will not be described in detail.

[0060] At the same time, compared with the solution in the prior art in which the mounting frame 200 and the supporting frame 100 are hard-connected through the first vibration damping assembly 400, the present invention provides two first elastic members 430 in the first vibration damping assembly 400, so that the first vibration damping assembly 400 can reduce vibration both in the direction close to the mounting frame 200 and in the direction close to the supporting frame 100, thereby improving the vibration damping effect of the first vibration damping assembly 400 and improving the protection strength of the main control board protection device.

[0061] In one embodiment, a plurality of first vibration reduction assemblies 400 are arranged at intervals along the circumference of the support frame 100, thereby further improving the vibration reduction effect of the vibration reduction structure 300, improving the vibration reduction effect of the main control board protection device, and improving the protection of the main control board.

[0062] In the embodiment of the present invention, the first connecting rod 440 is disposed obliquely in the depth direction of the mounting groove 210 .

[0063] Specifically, for the convenience of description, the depth direction of the mounting groove 210 is defined as the up-down direction, and the first fixing rod 410 is disposed at the upper end of the mounting frame 200, that is, the end of the first connecting rod 440 connected to the first slider 420 is located at the upper end, and the end of the first connecting rod 440 connected to the support frame 100 is located at the lower end. In one embodiment, the end of the first connecting rod 440 connected to the support frame 100 is disposed close to the second vibration reduction assembly 500. Here, the inclination angle of the first connecting rod 440 is not limited.

[0064] It can be understood that, compared with the first connecting rod 440 extending in a direction perpendicular to the depth direction of the mounting groove 210, the inclined setting of the first connecting rod 440 allows the first vibration damping assembly 400 to damp vibrations in multiple directions, thereby increasing the vibration damping range of the first vibration damping assembly 400, improving the vibration damping effect of the first vibration damping assembly 400, and improving the protection of the main control board by the main control board protection device.

[0065] In an embodiment of the present invention, the second vibration damping assembly 500 includes a second fixed rod 510, a second slider 520, a second elastic member 530 and a second connecting rod 540. The second fixed rod 510 is fixed to the support frame 100, the second slider 520 can slide along the second fixed rod 510, the second elastic member 530 is arranged on the second fixed rod 510 and is connected to the second slider 520, and the two ends of the second connecting rod 540 are respectively rotatably connected to the second slider 520 and the mounting frame 200.

[0066] Specifically, in the scheme shown in the figure of the present invention, one end of the second fixing rod 510 is fixed on the support frame 100, and the other end is a free end. In one embodiment, the support frame 100 is provided with a second fixing seat 133, the second fixing seat 133 is provided with a second fixing groove, and the second fixing seat 133 is also provided with a third fixing hole connected to the second fixing groove, and one end of the second fixing rod 510 is provided with a fourth fixing hole, the second fixing rod 510 extends into the second fixing groove, and the third fixing hole corresponds to the fourth fixing hole, and screws or bolts pass through the third fixing hole and the fourth fixing hole, so that the second fixing rod 510 is installed on the support frame 100. In one embodiment, the end of the second fixing rod 510 extending into the second fixing groove is hollow, so that it is convenient to penetrate the screws or bolts and other structural parts, and it is also conducive to the lightweight of the second fixing rod 510. Of course, in other embodiments, the second fixing rod 510 and the support frame 100 can also be connected by welding or other methods.

[0067] The second slider 520 is disposed on the second fixing rod 510, and the second slider 520 can slide along the length direction of the second fixing rod 510. At the same time, a second elastic member 530 is also installed on the second fixing rod 510, and one end of the second elastic member 530 is connected to the second slider 520. In this way, when the second slider 520 slides along the second fixing rod 510, the second elastic member 530 is deformed. In one embodiment, the second elastic member 530 can be configured as a spring, a spring sheet, etc., and the specific structure of the second elastic member 530 is not limited here.

[0068] One end of the second connecting rod 540 is rotatably connected to the second slider 520. In one embodiment, a through hole is provided at one end of the second connecting rod 540, and a through hole is also provided on the second slider 520. Connectors such as bolts pass through the two through holes in sequence, thereby connecting the second slider 520 and the second connecting rod 540, and allowing the second slider 520 and the second connecting rod 540 to rotate relative to each other. Of course, in other embodiments, the second slider 520 and the second connecting rod 540 can also achieve relative rotation through a universal joint.

[0069] The other end of the second connecting rod 540 is rotatably connected to the mounting frame 200. In one embodiment, the mounting frame 200 is provided with a second hinge seat 230, the second hinge seat 230 is provided with a through hole, and the other end of the second connecting rod 540 is also provided with a through hole, and bolts and other connecting members pass through the two through holes in sequence, thereby connecting the second connecting rod 540 and the mounting frame 200, and allowing the second connecting rod 540 and the mounting frame 200 to rotate relative to each other. Of course, in other embodiments, the second connecting rod 540 and the mounting frame 200 can also achieve relative rotation through a universal joint.

[0070] In this way, the support frame 100, the second fixing rod 510, the second slider 520, the second connecting rod 540 and the installation frame 200 are connected in sequence, thereby realizing a vibration-damping connection between the support frame 100 and the installation frame 200. When the support frame 100 is vibrated, the vibration is transmitted to the second slider 520 through the second fixing rod 510. Under the action of external force vibration, the second slider 520 compresses the second elastic member 530, causing the second elastic member 530 to deform, thereby absorbing part of the vibration; at the same time, as the second slider 520 slides on the second fixing rod 510, the second connecting rod 540 and the second slider 520 rotate relative to each other, so that part of the vibration is converted into the relative rotation between the second connecting rod 540 and the second slider 520, thereby absorbing part of the vibration; as the second connecting rod 540 and the second slider 520 rotate relative to each other, the second connecting rod 540 and the installation frame 200 also rotate relative to each other, thereby further absorbing part of the vibration. In this way, the external force vibration can be transmitted to the main control board after being absorbed and dispersed layer by layer, so that the vibration of the main control board is greatly reduced, thereby improving the vibration reduction effect of the main control board protection device and improving the protection of the main control board.

[0071] Of course, in other embodiments, the second vibration reduction assembly 500 may also be a spring with two ends respectively connected to the support frame 100 and the installation frame 200, which can also achieve a vibration reduction effect.

[0072] In an embodiment of the present invention, a second sliding groove 511 is provided in the second fixed rod 510, and the second sliding block 520 is slidably provided in the second sliding groove 511, and a portion of the second sliding block 520 extends out of the second sliding groove 511 to be rotatably connected to the second connecting rod 540; a second elastic member 530 is provided between the second sliding block 520 and the bottom wall of the second sliding groove 511.

[0073] Specifically, in the solution shown in the figure of the present invention, a second slide groove 511 for sliding the second slider 520 is further provided in the second fixed rod 510, and the second slide groove 511 is extended along the length direction of the second fixed rod 510. At the same time, a second opening 512 corresponding to the second slide groove 511 is also provided on the second fixed rod 510, and the second opening 512 is also a notch of the second slide groove 511. The second slider 520 is provided in the second slide groove 511, and at least part of the second slider 520 is exposed from the second opening 512, so as to facilitate the rotation connection between the second slider 520 and the second connecting rod 540.

[0074] It can be understood that along the length direction of the second slide groove 511, the second slide groove 511 has two opposite groove bottom walls, and the second slider 520 is arranged at one end of the second slide groove 511 close to the installation frame 200. In the unstressed state, the second slider 520 contacts the groove bottom wall of the second slide groove 511 close to the installation frame 200. A second elastic member 530 is arranged between the second slider 520 and the groove bottom wall of the first slide groove 411 close to the support frame 100, that is, a second elastic member 530 is arranged in the second slide groove 511, and the second elastic member 530 is located at one end of the second slider 520 close to the support frame 100. The arrangement of the second slide groove 511 provides a guide for the deformation of the second elastic member 530, and also provides a guide for the sliding of the second slider 520.

[0075] Thus, when the second slider 520 slides under the action of external force, the second slider 520 will compress the second elastic member 530, and the deformation of the second elastic member 530 can absorb part of the vibration. As the second elastic member 530 continues to be compressed, when the second elastic member 530 is compressed to the limit, the second slider 520 will be driven to slide in the opposite direction under the action of its own deformation force, and at the same time absorb part of the vibration. This is repeated to absorb the vibration.

[0076] At the same time, the second elastic member 530 is arranged at one end of the second slider 520 facing the support frame 100, so that the second connecting rod 540 can provide sufficient support force for the installation frame 200, so that the second vibration reduction assembly 500 can provide vibration reduction for the installation frame 200 while also providing support for the installation frame 200, so as to stably set the installation frame 200 in the support frame 100. In this way, it is beneficial for the second vibration reduction assembly 500 to keep the installation frame 200 in a stable position, and it is beneficial for the main control board to keep a stable position, so as to prevent the main control board from being displaced or damaged due to vibration.

[0077] In one embodiment, a plurality of second vibration reduction assemblies 500 are arranged at intervals along the circumference of the support frame 100, thereby further improving the vibration reduction effect of the vibration reduction structure 300, improving the vibration reduction effect of the main control board protection device, and improving the protection of the main control board.

[0078] In one embodiment, a plurality of first vibration damping assemblies 400 and a plurality of second vibration damping assemblies 500 are respectively arranged at intervals along the circumference of the support frame 100, and the first vibration damping assemblies 400 and the second vibration damping assemblies 500 are arranged at intervals along the depth direction of the mounting groove 210. In this way, the vibration damping effect of the vibration damping structure 300 is further improved, and the protection of the main control board is further improved.

[0079] In one embodiment, multiple first vibration damping assemblies 400 and multiple second vibration damping assemblies 500 are staggered along the depth direction of the mounting groove 210, so that the vibration damping structure 300 can be evenly distributed in the depth direction of the mounting groove 210 and the circumferential direction of the support frame 100, thereby further improving the vibration damping effect of the main control board protection device.

[0080] In the embodiment of the present invention, the second connecting rod 540 is disposed obliquely in the depth direction of the mounting groove 210 .

[0081] Specifically, for the convenience of description, the depth direction of the mounting groove 210 is defined as the up-down direction, and the second fixing rod 510 is disposed at the lower end of the support frame 100, that is, the end of the second connecting rod 540 connected to the second slider 520 is located at the lower end, and the end of the second connecting rod 540 connected to the mounting frame 200 is located at the upper end. In one embodiment, the end of the second connecting rod 540 connected to the mounting frame 200 is disposed close to the first vibration reduction assembly 400. Here, the inclination angle of the second connecting rod 540 is not limited.

[0082] It can be understood that, compared with the second connecting rod 540 extending in a direction perpendicular to the depth direction of the mounting groove 210, the inclined setting of the second connecting rod 540 allows the second vibration damping assembly 500 to damp vibrations in multiple directions, thereby increasing the vibration damping range of the second vibration damping assembly 500, improving the vibration damping effect of the second vibration damping assembly 500, and improving the protection of the main control board by the main control board protection device.

[0083] In the embodiment of the present invention, the support frame 100 includes a fixed outer frame 110 and a support inner frame 130 . The support inner frame 130 is provided with a support groove 140 . An elastic frame 120 is provided between the fixed outer frame 110 and the support inner frame 130 .

[0084] Specifically, the side close to the main control board is defined as the inner side, and the side away from the main control board is defined as the outer side. In the direction from the outside to the inside, a fixed outer frame 110, an elastic frame 120, a supporting inner frame 130 and an installation frame 200 are sequentially provided, and the fixed outer frame 110 is used to connect with other structures, so as to realize the installation and fixation of the main control board protection device. A vibration reduction structure 300 is provided between the supporting inner frame 130 and the installation frame 200, and the supporting inner frame 130 is used to provide support for the installation frame 200. The fixed outer frame 110 and the supporting inner frame 130 are connected through the elastic frame 120. It can be understood that the elastic frame 120 is configured as a material with elastic deformation. In one embodiment, the elastic frame 120 is made of silicone or rubber material, and the specific material of the elastic frame 120 is not limited. In one embodiment, the fixed outer frame 110 and the supporting inner frame 130 are configured as hard materials, such as sheet metal, stainless steel, etc., and the specific materials of the fixed outer frame 110 and the supporting inner frame 130 are not limited.

[0085] In this way, when vibration occurs under the action of external force, the vibration is transmitted to the elastic frame 120 through the fixed outer frame 110, and the elastic frame 120 can absorb and disperse part of the impact, and make the supporting inner frame 130 have a moving deformation or displacement in the fixed outer frame 110, so as to better absorb and release the impact. In other words, part of the impact is converted into kinetic energy of the supporting inner frame 130, which is gradually released under the change of the small displacement of the supporting inner frame 130, thereby reducing the vibration transmitted to the vibration reduction structure 300, and further improving the vibration reduction effect of the main control board protection device.

[0086] In an embodiment of the present invention, corresponding first through holes 111, second through holes and third through holes 131 are respectively provided on the fixed outer frame 110, the elastic frame 120 and the supporting inner frame 130, and the connecting member passes through the first through holes 111, the second through holes and the third through holes 131 in sequence to connect the fixed outer frame 110, the elastic frame 120 and the supporting inner frame 130.

[0087] Specifically, in the solution shown in the figure of the present invention, in the depth direction of the mounting groove 210, the fixed outer frame 110 is provided with a first through hole 111, the elastic frame 120 is provided with a second through hole, and the supporting inner frame 130 is provided with a third through hole 131. When the fixed outer frame 110, the elastic frame 120 and the supporting inner frame 130 are installed together, the first through hole 111, the second through hole and the third through hole 131 correspond to each other, and bolts, fixing rods and other connecting parts pass through the first through hole 111, the second through hole and the third through hole 131, thereby realizing the assembly of the supporting frame 100. In one embodiment, along the circumference of the supporting frame 100, the fixed outer frame 110, the elastic frame 120 and the supporting inner frame 130 are respectively provided with a plurality of corresponding first through holes 111, second through holes and third through holes 131, thereby improving the connection stability of the supporting frame 100.

[0088] Of course, in other embodiments, the fixed outer frame 110 , the elastic frame 120 and the supporting inner frame 130 may also be connected by bonding.

[0089] The present invention also provides a robot, which includes a main control board and a main control board protection device.
