[0049] Please refer to Figure 1 , Figure 1 is a perspective view of an embodiment of the boxing robot 10 provided in the present application, and the boxing robot 10 in the embodiment includes a trunk module 20 and a waist driving module 30.

[0050] Please refer to Figure 1 and Figure 2 , Figure 2 is Figure 1The torso module 20 comprises a torso 21, an arm assembly 22 and an arm driving mechanism 23. The arm assembly 22 is movably mounted on the torso 21, and the arm driving mechanism 23 is connected with the arm assembly 22, so that the arm driving mechanism 23 drives the arm assembly 22 to perform a punching action or a fist closing action along a preset trajectory.

[0051] The arm assembly 22 comprises a left arm assembly 22a and a right arm assembly 22b, and the arm driving mechanism 23 is connected with the left arm assembly 22a and the right arm assembly 22b respectively, so that the arm driving mechanism 23 can drive the left arm assembly 22a to perform a punching action or a fist closing action, and drive the right arm assembly 22b to perform a punching action or a fist closing action. In the embodiment, the left arm assembly 22a and the right arm assembly 22b have the same structure, and therefore, the description of the arm assembly 22 below refers to the description of the left arm assembly 22a and the right arm assembly 22b.

[0052] Optionally, the left arm assembly 22a can be connected to one side of the torso 21, and the right arm assembly 22b can be connected to the other side of the torso 21.

[0053] In an optional embodiment, the left arm assembly 22a and the right arm assembly 22b can be symmetrically arranged with a central axis plane when they are in the same state.

[0054] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 3 are Figure 2 a state diagram of the small arm 222 performing a fist closing action, Figure 4 are Figure 3 a state diagram of the small arm 222 performing a punching action, Figure 5 is a perspective structural diagram of another embodiment of the boxing robot 10 provided by the present application, Figure 6 are Figure 5 a perspective structural diagram of the arm assembly 22, Figure 7 are Figure 6 a state diagram of the small arm 222 performing a fist closing action, Figure 8 are Figure 7Fig. 2 is a schematic view of the arm assembly 22 in a state of performing a punching action, the arm assembly 22 comprising a large arm 221, a small arm 222 and a driving member 223, the first end of the large arm 221 being hingedly connected to one side of the torso 21 via a first hinging shaft 201, the first end of the small arm 222 being hingedly connected to the second end of the large arm 221 via a second hinging shaft 202, and the driving member 223 being connected to the torso 21 and the first end of the small arm 222 respectively, so that the torso 21, the large arm 221, the small arm 222 and the driving member 223 jointly form a "four-bar linkage structure".

[0055] In the embodiment, the connection point of the driving member 223 to the torso 21 is arranged at a position spaced apart from the connection point of the first end of the large arm 221 to the torso 21, and the connection point of the driving member 223 to the first end of the small arm 222 is arranged at a position away from the second end of the small arm 222 in the direction of the connection point of the first end of the large arm 221 to the second end of the small arm 222.

[0056] In an optional embodiment, the material density of the small arm 222 is less than the material density of the large arm 221.

[0057] In an optional embodiment, the small arm 222 comprises a main body portion 2221 and a soft layer 2222 sleeved on the main body portion 2221.

[0058] In an optional embodiment, the main body portion comprises a hollow portion, for example, the main body portion can be a hard hollow tube, and the soft layer can be foam or the like, which is not limited here.

[0059] Optionally, by reducing the weight of the small arm 222, the punching speed of the small arm 222 can be effectively improved, so as to improve the training effect and prevent excessive collision with the user and reduce the harm to the user.

[0060] In the embodiment as shown in Figs. 1 and 2, Figure 3 and Figure 4 In an embodiment, the driving member 223 is a hard driving member, which is hingedly connected to the torso 21 and the first end of the small arm 222 respectively, so that when the large arm 221 rotates in the first direction A1, the hard driving member pulls the small arm 222 to perform a punching action.

[0061] Optionally, the hinging shaft of the hard driving member to the torso 21 is parallel to the first hinging shaft 201, and the hinging manner of the hard driving member to the small arm 222 can be a spherical hinge manner or a universal hinge manner.

[0062] Specifically, when the arm driving mechanism 23 drives the large arm 221 to rotate in the first direction A1, i.e. Figure 3When the upper arm 221 rotates upwards, the driving component 223 also rotates in the first direction A1. Since both the upper arm 221 and the driving component 223 are hinged to the torso 21, the pivot positions of the first end of the upper arm 221 and the torso 21 are different. That is, the rotation axis of the upper arm 221 and the rotation axis of the driving component 223 are not in the same position. Therefore, the movement trajectory of the second end of the upper arm 221 and the movement trajectory of the second end of the driving component 223 are also different. This results in the upper arm 221 rotating in the first direction A1 as follows: Figure 4 As shown, the other end of the drive component 223 pulls the forearm 222 to rotate relative to the upper arm 221 in a direction away from the upper arm 221, which is to perform a punching action.

[0063] In such Figure 7 and Figure 8 In another embodiment shown, the drive member 223 is a flexible drive member, so that when the upper arm 221 rotates in the first direction A1, the flexible drive member pulls the lower arm 222 to perform a punching action.

[0064] Specifically, when the boom 221 rotates in the first direction A1, it is in accordance with the above... Figure 3 and Figure 4 The principle is the same as that of the embodiment shown, and the second end of the flexible drive component is as follows: Figure 7 As shown, pulling the forearm 222 to rotate relative to the upper arm 221 in a direction away from the upper arm 221 constitutes a punching motion. In practical applications, flexible drive components such as flexible ropes or flexible belts can be used, which are relatively inexpensive.

[0065] The arm assembly 22 in this embodiment also includes an elastic element 224, which is connected to one of the torso 21 and the forearm 222 and the upper arm 221 respectively, so that when the upper arm 221 rotates in the second direction A2, the forearm 222 performs a fist retraction action under the elastic force of the elastic element 224.

[0066] Specifically, as mentioned above Figure 3 and Figure 4 In one embodiment shown, when the drive member 223 is a rigid drive member, the elastic member 224 is connected to the torso 21 and the upper arm 221 respectively.

[0067] In an optional embodiment, the connection point between the elastic member 224 and the torso 21 can coincide with the connection point between the drive member 223 and the torso 21 on the projection of the first connection surface 21a, thereby reducing the need for drilling holes in the torso 21.

[0068] As described above Figure 7 and Figure 8 In another embodiment shown, when the drive member 223 is a flexible drive member, the elastic member 224 connects the upper arm 221 and the lower arm 222 respectively.

[0069] In an alternative embodiment, the elastic member 224 is connected to the second end of the large arm 221 and the first end of the small arm 222 respectively.

[0070] For example, in the above embodiment shown in Figure 3 and Figure 4 , when the large arm 221 rotates in the first direction A1, the small arm 222 overcomes the elastic force of the elastic member 224, so that the elastic member 224 generates elastic force. Therefore, when the large arm 221 rotates in the second direction A1 as shown in Figure 8 , the elastic force of the elastic member 224 pulls the small arm 222 to rotate relative to the large arm 221 in the direction close to the large arm 221, i.e. to perform the fist closing action.

[0071] Alternatively, when the large arm 221 rotates in the second direction A2 as shown in Figure 8 , it can be driven by the arm driving mechanism 23 to rotate in the second direction A2, or it can rotate in the second direction A2 under the action of gravity after the arm driving mechanism 23 is deactivated, which is not limited here.

[0072] In an alternative embodiment, the elastic member 224 can be a tension spring. Compared with a torsion spring, although the elastic force will also change with the length, the force arm of the elastic member 224 to the rotation axis of the small arm 222 is getting shorter (for example, the distance between the elastic member 224 and the small arm 222 and the large arm is getting shorter when the small arm 222 rotates relative to the large arm 221), so that the torque provided by the elastic member 224 to the small arm 222 actually changes little and does not greatly interfere with the fist closing action of the small arm 222, thereby reducing the influence of the rotation effect of the small arm 222 relative to the large arm 221. Figure 6 In other embodiments, the elastic member 224 can also be a torsion spring, which is not limited here.

[0073] Similarly, in another embodiment shown in

[0074] and Figure 7 , when the flexible belt driving member pulls the small arm 222 to perform the fist closing action, the small arm 222 overcomes the elastic force of the elastic member 224, so that the elastic member 224 generates elastic force. When the large arm 221 rotates in the second direction A1 as shown in Figure 8 , since the flexible belt driving member only has a pushing force but no pulling force, the second end of the flexible belt driving member cannot pull the small arm 222 to perform the fist closing action. In this case, the small arm 222 is pulled relative to the large arm 221 in the direction close to the large arm 221 by the elastic force of the elastic member 224, i.e. to perform the fist closing action. Figure 8

[0075] ​Please refer to the following: Figure 6 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , Figure 9 yes Figure 5 Frontal view of the mid-torso 21 Figure 10 yes Figure 6 A schematic diagram of the trajectory of the second end of the forearm 222 on the top-view projection plane of the torso 21. Figure 11 , Figure 12 and Figure 13 , Figure 11 yes Figure 5 A three-dimensional structural diagram of the midsection. Figure 12 yes Figure 5 Top view of the midsection. Figure 13 yes Figure 12 The diagram shows the central axis surface P1 and the first connecting surface 21a in the M direction. The torso 21 is used to drive the upper arm 221 to rotate during rotation. The torso 21 is defined with a central axis surface P1. The central axis surface P1 includes the rotation axis III of the torso 21 and is perpendicular to the left-looking direction of the torso 21, so that when the torso 21 rotates in the direction toward the central axis surface P1 and the upper arm 221 rotates relative to the torso 21, the second end of the forearm 222 can perform a punching or retracting action along a preset trajectory.

[0076] In this configuration, the central axis I of the first hinge shaft 201 and the central axis II of the second hinge shaft 202 are not coplanar. The axial direction of the second hinge shaft 202, i.e., the extension direction of the central axis II of the second hinge shaft 202, is inclined relative to the extension direction of the rotation axis III of the torso 21. This causes the forearm 222, as shown in Figure 9, to deflect at a predetermined angle relative to the upper arm 221 toward the rotation axis III of the torso 21. Consequently, when the second end of the forearm 222 performs a punching or retracting motion along a predetermined trajectory L1, as shown in Figure 9... Figure 10 As shown, the projection of the preset trajectory L1 onto the defined projection surface in the top view direction of the torso 21 is "straight line" or close to "straight line", which makes the second end of the forearm 222 achieve a "straight punch" effect when performing punching or retracting movements, which is more in line with the human boxing effect and has a better training effect.

[0077] When a person throws a punch, the upper body usually rotates before the fist strikes. Therefore, by setting up the torso 21 in the direction of the central axis plane P1 and the upper arm 221 rotates relative to the torso 21, the second end of the forearm 222 performs a punching or retracting motion along a preset trajectory. In addition to achieving a "straight punch" effect, this can better simulate the punching motion of the human body and achieve the effect of "real person" training.

[0078] It can be understood that the preset angle can be set according to the angle of the central axis II of the second hinge shaft 202 relative to the rotation axis III of the torso 21, for example, the deflection angle of the central axis II of the second hinge shaft 202 is adjusted based on the rotation axis III of the torso 21, that is, the preset angle of the large arm 221 deflected towards the rotation axis III of the torso 21 can be adjusted, so in actual application, the preset angle can be set according to the needs, which is not limited.

[0079] The preset trajectory L1 includes a punching starting point L11. When the large arm 221 rotates relative to the torso 21 and the torso does not rotate, the second end of the small arm 222 can move along the first trajectory L2, the first trajectory L2 includes the punching starting point L11 and the projection on the defined projection plane in the top view of the torso 21 is a first arc shape away from the central axis plane P1. When the torso 21 rotates and the large arm 221 does not rotate relative to the torso 21, the second end of the small arm 222 can move along the second trajectory L3, the second trajectory L3 includes the punching starting point L11 and the projection on the defined projection plane in the top view of the torso 21 is a second arc shape, so when the torso 21 rotates towards the central axis plane P1 and the large arm 221 rotates relative to the torso 21, the movement trends of the first trajectory L2 and the second trajectory L3 are combined, so that when the second end of the small arm 222 performs a punching action or a fist closing action along the preset trajectory L1, as shown in Figure 10 The projection of the preset trajectory L1 on the defined projection plane in the top view of the torso 21 is a straight line or close to a straight line.

[0080] Referring to Figure 6 , Figure 11 , Figure 12 and Figure 13 , one side of the torso 21 includes a first connecting surface 21a, the first end of the small arm 222 includes a second connecting surface 222a, the first end of the large arm 221 is hinged to the torso 21 on the first connecting surface 21a through the first hinge shaft 201, the second end of the large arm 221 is hinged to the small arm 222 on the second connecting surface 222a through the second hinge shaft 202, the driving member 223 is connected to the torso 21 on the first connecting surface 21a and connected to the small arm 222 on the second connecting surface 222a, respectively, and the second connecting surface 222a is inclined relative to the first connecting surface 21a.

[0081] The torso 21 is defined to form a reference surface P2, the angle α1 between the reference surface P2 and the central axis plane P1 is 0-35°, and the angle α2 between the first connecting surface 21a and the reference surface P2 is 10-30°, for example, the angle α1 is 0°, 10°, 30° and 35°, and the angle α2 is 10°, 20°, 30°.

[0082] It can be understood that the central axis plane P1 and the reference plane P2 are both virtual planes defined for the purpose of explaining the first connecting surface 21a.

[0083] Specifically, the reference plane P2 includes the rotation axis III of the trunk 21, the reference plane P2 is arranged in line with the central axis plane P1 relative to the rotation axis III, the first connecting surface 21a and the reference plane P2 respectively include a definition line IV, the first connecting surface 21a and the reference plane P2 are arranged in line relative to the definition line IV, the definition line IV is arranged intersecting the rotation axis III, that is, the central axis plane P1 is deflected by an angle α1 relative to the rotation axis III, and then the reference plane P2 is formed, and then the reference plane P2 is deflected by an angle α2 relative to the definition line IV, and then the first connecting surface 21a is formed.

[0084] Among them, the first hinge shaft 201 is perpendicular to the first connecting surface 21a, and the second hinge shaft 202 is perpendicular to the second connecting surface 222a.

[0085] Please refer to Figure 14 , Figure 14 is Figure 6 The angle between the central axis I of the first hinge shaft 201 and the central axis II of the second hinge shaft 202 is shown in the figure, wherein the included angle α3 between the central axis I of the first hinge shaft 201 and the central axis II of the second hinge shaft 202 is 30-60°, such as the included angle α3 is 30°, 45°, 60°, wherein in the present embodiment, the included angle α3 between the central axis I of the first hinge shaft 201 and the central axis II of the second hinge shaft 202 refers to the included angle between the projection of the central axis I on the defined projection plane in the top view of the trunk and the projection of the central axis II on the defined projection plane in the top view of the trunk. By the setting mode of the included angle α3, when the forearm 222 is curled, the upper arm 221 can be kept vertical as shown, which is more in line with the state of human body curling and more beautiful. Figure 10

[0086] Please refer to Figure 7 and Figure 8 , the trunk 21 is provided with a first limiting portion 21b, which is arranged between the upper arm 221 and the flexible belt driving member, so that when the upper arm 221 is rotated to a first preset position in the first direction A1, the flexible belt driving member is arranged in multiple segments under the stopping action of the first limiting portion 21b, and / or when the upper arm 221 is rotated to a second preset position in the second direction A2, the first limiting portion 21a stops the upper arm 221.

[0087] Specifically, when the upper arm 221 is rotated to a first preset position in the first direction A1, the flexible belt driving member is arranged in multiple segments under the stopping action of the first limiting portion 21b, and / or when the upper arm 221 is rotated to a second preset position in the second direction A2, the first limiting portion 21a stops the upper arm 221. Figure 7 ​When the first arm 221 rotates in the first direction A1 and does not rotate to the first preset position, the flexible driving member is in a straightened state, at this time, the rotation center of the flexible driving member is at the position where the flexible driving member is connected to the trunk 21 at one end, and the other end connected to the small arm 222 rotates around the position as the rotation center of the movement track, that is, the small arm 222 performs a punching action under the pulling action of the movement track; when the first arm 221 rotates to the first preset position, the first limiting portion 21b stops the flexible driving member, so that the flexible driving member is in a state as shown in Figure 8 At this time, under the condition that the first arm 221 continues to rotate, the other end connected to the small arm 222 of the flexible driving member rotates around the first limiting portion 21b as the rotation center of the movement track, that is, compared with Figure 7 As shown in the middle, when the first arm 221 does not rotate to the first preset position, the movement track of the other end connected to the small arm 222 of the flexible driving member changes, so that the movement track of the small arm 222 when performing a punching action also changes. Through this setting mode, on the one hand, the movement track of the small arm 222 when performing a punching action is increased, so that the punching action of the small arm 222 is diversified, on the other hand, the movement range of the small arm 222 is increased, and the punching range of the small arm 222 is improved; and when the first arm 221 rotates to the second preset position in the second direction A1 as shown Figure 7 The first arm 221 is stopped by the first limiting portion 21b, so that the first arm 221 no longer continues to rotate, thereby maintaining the state as shown Figure 7 .

[0088] In actual application, the second end of the small arm 222 can be additionally provided with a boxing glove, when the user fights against the boxing robot 10, the pain caused by the boxing robot 10 hitting the user is reduced.

[0089] Referring to Figure 6 One of the first arm 221 and the small arm 222 is provided with a second limiting portion 222b, the second limiting portion 222b is used to stop the other one of the first arm 221 and the small arm 222 when the small arm 222 performs a punching action to a third preset position and / or stop the other one of the first arm 221 and the small arm 222 when the small arm 222 performs a boxing action to a fourth preset position.

[0090] For example, in the embodiment, the small arm 222 is provided with the second limiting portion 222b, as shown in Figure 6As shown, when the forearm 222 performs the fist closing action to the fourth preset position, the second limiting portion 222b abuts against the upper arm 221, thereby stopping the upper arm 221, so that the forearm 222 cannot continue to perform the fist closing action, thereby keeping the forearm 222 in the fist closing state at the fourth preset position. It can be understood that the principle of the second limiting portion 222b stopping the upper arm 221 when the forearm 222 performs the fist opening action to the third preset position is the same as this, and will not be described here.

[0091] Referring to Figure 6 The arm driving mechanism 23 comprises a driving assembly 23a and a transmission member, the driving assembly 23a is connected with the transmission member to drive the transmission member to reciprocate, and the two ends of the transmission member are respectively connected with the left arm assembly 22a and the right arm assembly 22b, so that when one of the left arm assembly 22a and the right arm assembly 22b performs the fist opening action, the other of the left arm assembly 22a and the right arm assembly 22b performs the fist closing action.

[0092] Specifically, the transmission member comprises a first transmission member 23b and a second transmission member 23c, the driving assembly 23a is respectively connected with one end of the first transmission member 23b and one end of the second transmission member 23c, the upper arm 221 comprises a left upper arm and a right upper arm, the forearm 222 comprises a left forearm and a right forearm, the driving member 223 comprises a left driving member and a right driving member, the other end of the first transmission member 23b is connected with the left upper arm, and the other end of the second transmission member 23c is connected with the right upper arm, the driving assembly 23a is used to drive the first transmission member 23b to drive the left upper arm to rotate when the driving assembly 23a moves along the third direction B1, so that the left forearm performs the fist opening action, and the driving assembly 23a is used to drive the second transmission member 23c to drive the right upper arm to rotate when the driving assembly 23a moves along the fourth direction B2, so that the right forearm performs the fist opening action, through this setting mode, only one driving assembly 23a can complete the fist opening action of the left forearm and the fist opening action of the right forearm respectively, which simplifies the overall structure and reduces the cost.

[0093] In an optional embodiment, the first transmission member 23b and the second transmission member 23c can all be transmission belts, which have the function of one-way transmission, when the driving assembly 23a can first drive the first transmission member 23b to drive the left upper arm to rotate to make the left forearm perform the fist opening action along the third direction B1, then the driving assembly 23a drives the second transmission member 23c to drive the right upper arm to rotate to make the right forearm perform the fist opening action along the fourth direction B2, at this time, the left upper arm will restore the fist closing state under the gravity and / or the elastic force of the elastic member 224 without the force of the first transmission member 23b until the next fist opening, similarly, when the driving assembly 23a drives the first transmission member 23b to drive the left upper arm to rotate to make the left forearm perform the fist opening action along the third direction B1, the right upper arm will also restore the fist closing state under the gravity and / or the elastic force of the elastic member 224 without the driving of the second transmission member 23c, thereby realizing the turn-taking fist opening of the left forearm and the right forearm.

[0094] In other embodiments, the first transmission member 23b and the second transmission member 23c can be a gear set or a synchronous belt, which can realize bidirectional force transmission, so that when one of the transmission members drives the left forearm and the right forearm to perform a punching action through the left driving member and the right driving member, the other of the left forearm and the right forearm performs a fist closing action. It can be understood that in the present embodiment, the left forearm is the forearm of the left arm assembly 22a, the left forearm is the forearm of the left arm assembly 22a, the right forearm is the forearm of the right arm assembly 22b, and the right forearm is the forearm of the right arm assembly 22b.

[0095] It can be understood that in actual application, the specific driving mode of the driving assembly 23a can be set according to actual needs, which is not limited.

[0096] Optionally, the transmission member 23b is a flexible transmission member, such as a flexible transmission belt, which reduces the cost.

[0097] Optionally, the first transmission member 23b and the second transmission member 23c can be integrated or independent of each other.

[0098] Referring to Figure 5 , the torso 21 is formed with a receiving cavity 210a, and the driving assembly 23a, the first transmission member 23b and the second transmission member 23c are arranged in the receiving cavity 210a.

[0099] The first transmission member 23b and the second transmission member 23c are a transmission belt or a gear set connected to the driving assembly 23a; and / or the punching robot 10 further comprises a head assembly 210b rotatably arranged on the torso 21, and the head assembly 210b is connected to the driving assembly 23a through a connecting shaft 210c, so that the driving assembly 23a drives the head assembly 210b to rotate left relative to the torso 21 when moving in the third direction B1, and the driving assembly 21a drives the head assembly 210b to rotate right relative to the torso 21 when moving in the second direction B2. Through this arrangement, when the left forearm performs a punching action, the head assembly 210b looks left, and when the right forearm performs a punching action, the head assembly 210b looks right, which is more consistent with the action of human fist.

[0100] Please refer to Figure 1 , Figure 5 , Figure 15 and Figure 16 , Figure 15 is Figure 1 a perspective view of the waist driving module 30 in Figure 16 is Figure 5A perspective view of the waist driving module 30, wherein the waist driving module 30 is connected with the torso 21, and the waist driving module 30 is used to drive the torso 21 to move in at least the front-rear freedom direction C, the left-right freedom direction D and the rotation freedom direction E, so that when the user exercises or trains through the punching robot 10, not only the user can realize the punching with the user through the arm assembly 22, but also the arm assembly 22 can be driven by the waist driving module 30 to move in at least the above three freedom directions, so as to simulate the dodging, punching in different positions and other operations in the punching process, and improve the exercise or training effect of the user.

[0101] The waist driving module 30 comprises a first driving mechanism 31, a second driving mechanism 32 and a third driving mechanism 33, and at least each of the first driving mechanism 31, the second driving mechanism 32 and the third driving mechanism 33 is used to drive the torso 21 to move in at least each of the front-rear freedom direction C, the left-right freedom direction D and the rotation freedom direction E.

[0102] In an embodiment as shown in the figure, Figure 15 The first driving mechanism 31 is used to drive the torso 21 to move in the front-rear freedom direction C, the second driving mechanism 32 is used to drive the torso 21 to move in the left-right freedom direction D, and the third driving mechanism 33 is used to drive the torso 21 to move in the rotation freedom direction E. One of the first driving mechanism 31, the second driving mechanism 32 and the third driving mechanism 33 is connected with the other two of the first driving mechanism 31, the second driving mechanism 32 and the third driving mechanism 33 respectively, and one of the second driving mechanism 32 and the third driving mechanism 33 is connected with the torso 21. In this embodiment, the first driving mechanism 31 is connected with the second driving mechanism 32 and the third driving mechanism 33 respectively, and the second driving mechanism 32 is connected with the torso 21.

[0103] Optionally, in this embodiment, the first driving mechanism 31, the second driving mechanism 32 and the third driving mechanism 33 have the same structure, and the difference only lies in the driving direction of the movement of the torso 21, so, Figure 15 The structure of the second driving mechanism 32 is taken as an example for description. The second driving mechanism 32 comprises a second motor 321 and a second transmission assembly 322. The second transmission assembly 322 comprises a third transmission wheel 3221 and a fourth transmission wheel 3222. The third transmission wheel 3221 is installed on the output shaft of the second motor 321, and the fourth transmission wheel 3222 is engaged with the third transmission wheel 3221 and connected with the torso 21, so that when the output shaft of the second motor 321 rotates, the torso 21 is driven to move in the left-right freedom direction D through the third transmission wheel 3221 and the fourth transmission wheel 3222 in turn.

[0104] In an embodiment as shown in the figure, Figure 16In another embodiment shown, the waist driving module 30 further comprises a steering mechanism 34, the first driving mechanism 31 and the second driving mechanism 32 are connected with the steering mechanism 34 respectively, one of the steering mechanism 34 and the third driving mechanism 33 is connected with the other one of the steering mechanism 34 and the third driving mechanism 33 and the torso 21 respectively, so that the first driving mechanism 31 and the second driving mechanism 32 are matched with each other and drive the torso 21 to move in the front and back freedom degree direction C and the left and right freedom degree direction D respectively through the steering mechanism 34, and the third driving mechanism 33 drives the torso 21 to move in the rotation freedom degree direction E, in this embodiment, taking the third driving mechanism 33 connected with the steering mechanism 34 and the torso 21 respectively as an example.

[0105] Specifically, the driving mode of the first driving mechanism 31 and the second driving mechanism 32 is linear driving mode, that is, the driving direction of the first driving mechanism 31 and the second driving mechanism 32 is the direction F shown, if there is no steering mechanism 34, then the first driving mechanism 31 and the second driving mechanism 32 can only drive the torso 21 to move linearly in the direction F, therefore, through the setting mode of the steering mechanism 34, the linear driving mode of the first driving mechanism 31 and the second driving mechanism 32 can be steered, so that the torso 21 can move in the front and back freedom degree direction C and the left and right freedom degree direction D. Figure 12

[0106] Optionally, in this embodiment, the first driving mechanism 31 and the second driving mechanism 32 adopt the driving mode of a lead screw motor.

[0107] Please refer to Figure 17 , Figure 17 is Figure 16 the exploded structure diagram of the steering mechanism 34 in

[0108] ​Specifically, when the first driving mechanism 31 and the second driving mechanism 32 drive the connecting piece 342 in the direction F, the connecting piece 342 drives the turning piece 343 to rotate relative to the bearing piece 341, so as to drive the torso 21 to move in the front-back freedom direction C and the left-right freedom direction D. For example, when the connecting piece 342 drives the turning piece 343 to rotate relative to the bearing piece 341 in the front-back freedom direction C, the torso 21 is driven to move in the front-back freedom direction C; when the connecting piece 342 drives the turning piece 343 to rotate relative to the bearing piece 341 in the left-right freedom direction D, the torso 21 is driven to move in the left-right freedom direction D.

[0109] Optionally, in the embodiment, the turning piece 343 is a universal joint.

[0110] Referring to Figure 1 The torso module 20 in the embodiment further comprises a plurality of detection units 24, which are respectively installed at different positions of the torso 21 to detect the hitting force of the punching object of the punching robot 10 at different positions of the torso 21.

[0111] The detection unit 24 comprises a pressure sensor (not shown in the figure) and a protective piece 241. The pressure sensor is installed on the torso 21, and the protective piece 241 covers the pressure sensor. When the user hits, the protective piece 241 is hit, so that the hitting force is transmitted to the pressure sensor. On the one hand, the protective piece 241 plays a protective role on the pressure sensor, and on the other hand, reduces the pain felt by the user when hitting. In actual application, the protective piece 241 can be a flexible protective piece or an elastic protective piece.

[0112] In an optional embodiment, the detection unit 24 can be an air bag pressure piece, which can be covered on the torso 21. The air bag pressure piece is in an inflated state, and after being hit, the internal air pressure changes. By detecting the change of the internal air pressure, the hit situation and area can be determined.

[0113] Optionally, since the air bag pressure piece is flexible, it can be used as a covering piece on the torso 21, and can also reduce the pain felt by the user when hitting. At the same time, the advantages of flexible covering and pressure detection are realized, and the cost is greatly reduced.

[0114] Referring to Figure 18 and Figure 19 , Figure 18 is Figure 1 an enlarged schematic view of the K1 part in Figure 19 is Figure 5The enlarged schematic diagram of part K2 shows that the boxing robot 10 in this embodiment also includes a support module 40. The support module 40 includes a first support mechanism 41 and a second support mechanism 42. The first support mechanism 41 is connected to the waist drive module 30 and the second support mechanism 42 respectively. The first support mechanism 41 and the second support mechanism 42 are adjustable so that the installation height of the torso 21 and the arm assembly 22 can be adjusted through the first support mechanism 41 and the second support mechanism 42 to meet the sparring operation of users of different heights.

[0115] One of the first support mechanism 41 and the second support mechanism 42 is provided with a locking part. The support module 40 also includes a locking mechanism 43. The locking mechanism 43 is used to lock the first support mechanism 41 and the second support mechanism 42 through the locking part. That is, after the first support mechanism 41 and the second support mechanism 42 are adjusted, the locking mechanism 43 locks the first support mechanism 41 and the second support mechanism 42 through the locking part.

[0116] In such Figure 18 In one embodiment shown, one of the first support mechanism 41 and the second support mechanism 42 is provided with a plurality of first locking parts 411, and the other of the first support mechanism 41 and the second support mechanism 42 is provided with a second locking part (not shown in the figure). Figure 14 Both the first locking part 411 and the second locking part are locking holes. During the adjustment process, the locking hole of the second locking part can be aligned with the locking hole of any of the first locking parts 411. Then, the locking mechanism 43 is sequentially inserted into the locking holes of the first locking part 411 and the second locking part to complete the locking operation of the first support mechanism 41 and the second support mechanism 42.

[0117] In such Figure 19 In another embodiment shown, the locking mechanism 43 is sleeved on the first support mechanism 41 or the second support mechanism 42 and threadedly connected to the first support mechanism 41 or the second support mechanism 42. After adjustment, the locking mechanism 43 rotates relative to the first support mechanism 41 or the second support mechanism 42 until it is stacked with the locking part 412, thereby pressing the first support mechanism 41 and the second support mechanism 42 through the locking part 412 to complete the locking operation of the first support mechanism 41 and the second support mechanism 42.

[0118] Please see Figure 20 , Figure 20 This is a three-dimensional structural diagram of an embodiment of the boxing platform 50 provided in this application. The boxing platform 50 in this embodiment includes a platform 51 and a plurality of boxing robots 10 in the above embodiments.

[0119] Multiple boxing robots 10 are respectively installed on the platform 51. When the second end of the forearm 222 of the multiple boxing robots 10 performs a punching action along a preset trajectory, the preset trajectory of at least one boxing robot 10 intersects with the preset trajectory of at least another boxing robot 10, thereby realizing the fighting operation of at least two boxing robots 10.

[0120] In an optional embodiment, the boxing robot 10 can be located within the preset trajectory of an adjacent boxing robot 10. That is, the boxing robot 10 can control the overall movement of its torso 21 and arm assembly 20 through the waist drive module 30. The overall movement trajectory of its torso 21 and arm assembly 20 can intersect with the preset trajectory of the second end of the forearm 222 of the adjacent boxing robot 10, so that it can be hit by the forearm 222 of the adjacent boxing robot 10. The overall movement trajectory can not intersect with the preset trajectory of the second end of the forearm 222 of the adjacent boxing robot 10, so that the boxing robot 10 can dodge through the waist drive module 30 and avoid being hit by the second end of the forearm 222 of the adjacent boxing robot 10, thereby effectively improving the entertainment effect of mutual fighting.

[0121] For example, with Figure 20 Taking two boxing robots arranged opposite each other as an example, the two boxing robots are boxing robot 10a and boxing robot 10b. When the forearm 222 of boxing robot 10a punches towards boxing robot 10b, the forearm 222 of boxing robot 10b also punches towards boxing robot 10a. Since the preset trajectories of the second ends of the forearms of the two boxing robots intersect, the second ends of the forearm 222 of boxing robot 10a and the second ends of the forearm 222 of boxing robot 10b can move to the same position, so the two can perform a fighting operation at that position.

[0122] Optionally, the platform 51 includes a platform body 511 and wheels 512. Multiple boxing robots 10 are respectively installed on the platform body 511, and the wheels 512 are connected to the platform body 511 so that the boxing platform 50 can be adjusted in position by the wheels 512, thereby improving the flexibility of the boxing platform 50.

[0123] The application has the beneficial effect that, different from the prior art, the boxing robot provided by the application comprises a trunk module, an arm assembly and an arm driving mechanism, the arm assembly is movably installed on the trunk, the arm driving mechanism is connected with the arm assembly, so that the arm driving mechanism drives the arm assembly to perform a punching action or a fist closing action along a preset path; a waist driving module is connected with the trunk, the waist driving module is used for driving the trunk to move at least in the front-rear freedom degree direction, the left-right freedom degree direction and the rotation freedom degree direction, so that when a user exercises or trains through the boxing robot, not only can the user realize a fight with the user through the arm assembly, but also can drive the arm assembly to move at least in the three freedom degree directions through the waist driving module, so as to simulate the operation of dodging and punching at different positions in the fight process, and improve the exercise or training effect of the user.

[0124] The above only describes some embodiments of the application, and does not limit the protection scope of the application, and any equivalent device or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the application.
