Description

Technical Field

[0001] The invention relates to the field of sports equipment, and in particular to a ball launching device. Background Art

[0002] Basketball is one of the most popular ball sports in the world. In basketball, shooting training is very important. Through training, athletes can improve their shooting skills and increase their scores in basketball games. In traditional training, athletes need to collect the basketballs scattered on the court after shooting many times in a row, and then continue training, or they need other people to practice with them and help pass the ball. Traditional training methods are not only time-consuming and manpower-consuming, but also affect training efficiency. A basketball serving machine is a training device used to train basketball players' shooting techniques. It can save the ball picking process in training and help athletes improve their reaction speed and accuracy in catching and shooting. By using a basketball serving machine, training efficiency can be improved, thereby improving shooting skills.

[0003] For example, the invention patent with publication number CN107050817A discloses a basketball serving machine, including: a base, a serving mechanism connected to the base, a supporting mechanism connected to the base, a net connected to the supporting mechanism, and a lower ball mechanism connected to the supporting mechanism and connected to the net; the serving mechanism includes: a base, a ball guide channel, and a serving assembly; the serving assembly includes: a mounting frame, a first friction wheel, a second friction wheel, a first serving motor, and a second serving motor; the first friction wheel is located above the second friction wheel.

The frame includes a base frame and a vertical pole. The lifting frame is installed on the vertical pole to form a liftable structure. An inclined brace is connected between the lifting frame and the base frame to form a reinforced fixing structure for the lifting frame through the inclined brace; the lower ball rack is installed on the lifting frame.

[0005] The utility model patent with publication number CN215538303U discloses a youth basketball sports equipment, including a base part, a horizontal swing mechanism, an elevation adjustment fixing mechanism, a serving assembly, a lifting support mechanism, a ball lowering mechanism, a ball receiving net frame part and a backboard part. The horizontal swing mechanism is installed on the base part, the elevation adjustment fixing mechanism is installed on the horizontal swing mechanism, and the serving assembly is installed on the elevation adjustment fixing mechanism, so that the serving assembly forms a structure that can simultaneously adjust the horizontal direction and the elevation angle.

[0006] The above schemes can collect dropped basketballs and launch them back to athletes, thereby improving the efficiency of basketball training. However, the serving methods are fixed. For example, the ball is launched corresponding to the position of the lower body of the human body. The operation is cumbersome, the overall size is large, and it is not convenient to carry and transport, which affects the popularization and use.

[0007] Therefore, there is an urgent need for a ball launching device that is more intelligent, simple to operate, and easy to use. Summary of the invention

[0020] Beneficial effects: Generally speaking, in ball sports, teammates will serve from a specific position and a specific direction. For example, in basketball, whether teammates serve on or off the court, they serve to a specific person and push their hands outward from the chest position of the body to serve (i.e., the standard serving posture). However, the serving mechanism of existing basketball serving devices is located at the bottom of the device, and the firing direction is fixed. If the firing direction is to be adjusted, the entire device can only be driven to adjust the firing direction, and the standard serving posture of manually serving from the chest cannot be simulated. If the height of the entire device is increased so that the serving mechanism can serve from the position corresponding to the chest, the size and weight of the entire device will increase, making the device bulky and inconvenient to carry around in the stadium.

[0021] In view of this, the present invention provides a new ball launching device, which makes the basketball launching position more consistent with the standard serving posture by setting a liftable serving mechanism, for example, the serving mechanism is raised to a certain height (such as corresponding to the chest position of the human body) by the lifting mechanism before serving. Furthermore, an angle adjustment mechanism is also provided to adjust the launching angle of the serving mechanism, so that not only can the ball be served from a higher position (such as corresponding to the chest position), but also the launching direction of the serving mechanism can be adjusted according to the actual launching direction, without the need to lift the height of the entire device as a whole, and without driving the entire device to rotate to adjust the launching angle, that is, by setting a liftable and rotatable serving mechanism.

[0022] Furthermore, the present invention adopts a redesigned serving mechanism, which makes the overall volume of the serving mechanism smaller and lighter than the traditional serving mechanism, so that the entire device can be lightweight and miniaturized. Compared with the traditional large and bulky serving mechanism, the redesigned serving mechanism also makes the design and strength requirements of the lifting mechanism lower, thereby further realizing the miniaturization and lightweight of the entire device.

[0023] Generally speaking, it is relatively simple to achieve the lifting of one target. However, to achieve the synchronous lifting of multiple targets at the same time and to achieve it in a limited space as much as possible, it is necessary to consider the reasonable space division and the distribution and coordination between the components. The present application provides a multi-stage lifting mechanism, which uses a power source to synchronously drive the synchronous lifting of multiple targets, so that there is no need to manually lift and adjust the positions of multiple targets separately, making the operation more convenient and helping to achieve the miniaturization and portability of the equipment.

[0024] Existing grid mechanisms are all implemented with telescopic rods, which require manual extension and retraction, and are inconvenient to operate, especially for users with short stature. If multiple electric telescopic rods such as hydraulic cylinders are used, not only is the cost high, but also the weight and cost of the entire device increase. The present application implements a foldable grid mechanism through a multi-link mechanism, and it can realize the contraction and extension of the entire grid with only one driving source, which is more convenient to operate than the traditional telescopic rod type.

DETAILED DESCRIPTION

Obviously, the described embodiments are 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 making creative work are within the scope of protection of the present invention.

[0034] In order to facilitate storage and serve from a standard position (e.g., corresponding to the human chest position, or a specified height), the present application provides a liftable serving mechanism. When it is not needed, the serving mechanism can be lowered to a first position (e.g., inside the storage housing 101), and when it is needed, the serving mechanism is raised to a second position (e.g., outside the storage housing 101 and corresponding to the human chest position; of course, users of different heights can be lifted to different heights to correspond to the chest position of users of different heights). Further, the serving mechanism of the present invention can also adjust the launch angle according to actual needs. Specifically, the launch angle of the serving mechanism can be adjusted separately by an angle adjustment component, without the need to rotate the angle of the device to achieve the adjustment of the launch angle. Furthermore, the device of the present invention also realizes a foldable grid frame through a multi-link mechanism, so that there is no need for manual operation to unfold or retract the grid frame. Furthermore, by setting a multi-stage lifting mechanism, the synchronous lifting of the three targets of the serving mechanism, the ball storage mechanism and the grid frame is achieved, which further simplifies the operation and helps to achieve the miniaturization and lightness of the entire device. The following will be described in detail in conjunction with specific embodiments and structural drawings.

[0035] Example 1: See Figure 1 , is a schematic structural diagram of an embodiment of a ball launching device provided by the present invention. Specifically, the basketball intelligent launching device comprises: a ball serving mechanism 2, a ball storage mechanism 3, a net frame mechanism 4 and a lifting mechanism 5.

[0036] See also Figure 1 and Figure 3 In this embodiment, the lifting direction in the figure is the Z-axis direction, also called the longitudinal direction, and the width direction and length direction of the entire device are respectively the X-axis and the Y-axis to construct a three-dimensional coordinate system. The subsequent embodiments will also use this coordinate system as a reference to describe the relationship between the various components.

[0037] In some embodiments, the ball launching mechanism 2 includes a launching assembly and an angle adjustment assembly. Figure 6a-Figure 7 The launching assembly includes a fourth mounting seat 208, a launching drive mechanism 206, a hitting mechanism 204, a connecting seat 207 and a transmission mechanism, and the angle adjustment assembly includes a rotating platform 209; wherein the launching drive mechanism 206, the hitting mechanism 204 and the connecting seat 207 are all arranged on the fourth mounting seat 208, and the end of the connecting seat 207 away from the fourth mounting seat 208 is hinged to the hitting mechanism 204, the launching drive mechanism 206 is driven to connect the hitting mechanism 204 through the transmission mechanism, the fourth mounting seat 208 is arranged on the rotating platform 209, and the rotating platform 209 is used to drive the fourth mounting seat 208 to rotate, thereby controlling the change of the launching angle.

[0038] Preferably, the rotating platform 209 is disposed at the bottom of the fourth mounting seat 208 and is driven to connect to the fourth mounting seat 208. In actual use, the rotating platform 209 can drive the fourth mounting seat 208 to rotate at multiple angles, thereby changing the hitting direction of the hitting mechanism 204 and achieving precise adjustment and control of the basketball launch angle. Preferably, the rotating platform 209 uses a rotary motor, which can be mounted on the first mounting seat 106, and its rotation output shaft is connected to the fourth mounting seat 208.

[0039] In other words, the connecting seat 207 is firmly arranged on the fourth mounting seat 208, ensuring the stability and reliability of the structure, and the end of the connecting seat 207 away from the fourth mounting seat is hinged to the striking mechanism 204, so that the striking mechanism 204 (for example, a rod) can flexibly swing or rotate within a certain range to meet the force requirements of the striking action.

[0040] See also Figure 6a-Figure 7 The transmission mechanism includes an electromagnetic clutch 210, a torque output shaft 211, a crank 212 and a connecting rod 205; the electromagnetic clutch 210 is rotationally connected to the launch drive mechanism 206 through the torque output shaft 211, the crank 212 is rotationally connected to the side of the electromagnetic clutch 210 away from the launch drive mechanism 206, and is installed on the torque output shaft 211, one end of the connecting rod 205 is rotationally connected to the crank 212, and the other end of the connecting rod 205 is transmission-connected to the striking mechanism 204.

[0041] Preferably, the connection point (or hinge point) where the connecting rod 205 is rotatably connected to the ball striking mechanism 204 is close to the middle of the ball striking mechanism 204, so that the connecting rod 205 plays a role in both conducting force and limiting position, and there is also a sufficient contact area between the ball striking mechanism 204 and the ball, so that the ball can be struck efficiently and accurately. Of course, the connection point where the connecting rod 205 is rotatably connected to the ball striking mechanism 204 may not be close to the middle, and can be adjusted according to actual needs, for example, according to the torque required by different balls, the launch speed, the ball outlet angle, etc., adaptive adjustment can be made.

[0042] In this embodiment, the electromagnetic clutch 210 can adopt the electromagnetic clutch commonly used in the art, specifically, it includes an active end and a driven end. When the electromagnetic clutch 210 is not energized, its active end can rotate along with the launching drive mechanism 206, while the driven end does not rotate, and the connection point between the crank 212 and the connecting rod 205 arranged on the driven end is always located at the initial position under the action of gravity and the pressure of the striking mechanism 204; and when the electromagnetic clutch 210 is energized, the active end and the driven end are instantly attracted under the action of the electromagnetic field, so that the crank 212 rotates under the drive of the driven end, so that the hinge point between the connecting rod 205 and the crank 212 rotates and drives the striking mechanism 204 to complete the striking, such as Figure 6c Correspondingly, if the power is off at this time, under the action of gravity and the pressure of the striking mechanism, the crank drives the connecting rod to reset, that is, the connection point between the two is reset to the initial position, such as Figure 6b shown.

[0043] Of course, in other embodiments, in order to adjust the strength of the serve, before the electromagnetic clutch 210 is energized, the launch drive mechanism 206 can be used to drive the active end along the hitting direction ( Figure 6b The electromagnetic clutch 210 is then powered on to rotate the crank and the connecting rod in the direction of hitting the ball by a certain angle, thereby providing a greater explosive force to achieve a longer serving distance. Of course, if the serving force is to be reduced, the launching drive mechanism 206 first drives the active end to rotate in the direction of hitting the ball by a certain angle, and then the electromagnetic clutch 210 is powered on to rotate the crank and the connecting rod in the direction of hitting the ball by a smaller angle, thereby providing a smaller hitting force. Of course, in other embodiments, a spring or other structure can be added to change the initial position to achieve a change in force.

[0044] It can be seen that when the launch drive mechanism 206 receives the control signal and starts to operate, the generated power is transmitted to the electromagnetic clutch 210 through the torque output shaft 211; when the electromagnetic clutch 210 receives the control signal and is energized, the power from the launch drive mechanism 206 is transmitted to the striking mechanism 204 through the crank 212 and the connecting rod 205, so that the striking mechanism 204 completes the striking action at the set speed and force.

[0045] The design of the transmission mechanism not only realizes the efficient transmission of driving force, but also ensures the accuracy and stability of hitting the ball. Through the coordinated action of the electromagnetic clutch 210, the torque output shaft 211, the crank 212 and the connecting rod 205, the hitting mechanism 204 can continuously and stably complete the hitting and launching tasks.

[0046] In this embodiment, one end of the transmission mechanism is driven and connected to the launch drive mechanism 206 to ensure the stable input of the power source, while the other end is driven and connected to the striking mechanism 204 to achieve effective conversion and transmission of power. The transmission mechanism is used to drive the striking mechanism 204 to launch and reset under the drive of the launch drive mechanism 206.

[0047] In some embodiments, the launch drive mechanism 206 includes a launch drive motor, so that the launch drive mechanism 206 not only has a strong driving force and stable operating performance, but can also accurately adjust the rotation speed and torque according to control instructions, ensuring that the striking mechanism 204 can complete the striking action at the set speed and strength.

[0048] In some embodiments, the rotating platform 209 includes a rotary motor, which serves as a driving component and has precise angle control and stable operating performance. It can flexibly adjust the rotation angle of the fourth mounting seat 208 according to control instructions, thereby achieving precise control of the launch angle.

[0049] Furthermore, in some embodiments, the transmission mechanism also includes a reset mechanism. When the striking mechanism 204 completes the striking action, the transmission mechanism can automatically (for example, after the electromagnetic clutch is powered off, the crank and the connecting rod can automatically reset under the action of gravity and the pressure of the striking mechanism) or under corresponding control instructions (for example, after the electromagnetic clutch is powered off, the electromagnetic clutch is first reset by the launch drive mechanism and then the power is cut off) guide the striking mechanism 204 to return to the initial position, so as to be fully prepared for the next launch, thereby making the entire launching process smoother and more efficient.

[0050] In some embodiments, the serving mechanism 2 also includes a shell 201, which is connected to the side of the fourth mounting seat 208 away from the rotating platform 209, and the shell 201 has an opening facing the fourth mounting seat 208 away from the rotating platform 209. The shell 201 effectively protects the various components inside the serving mechanism.

[0051] See also Fig.10 and Fig.11 In other embodiments, the ball serving mechanism 2 further includes a ball holding mechanism 216 and a protective cover 215, the protective cover 215 is detachably connected to the ball holding mechanism 216, or the protective cover 215 and the ball holding mechanism 216 are integrally formed, the protective cover 215 covers the outside of the launching drive mechanism, and the protective cover 215 is detachably connected to the fourth mounting seat 208.

[0052] The protective cover 215 provides necessary protection for the launch drive mechanism 206, ensuring the safety and stability of the entire ball-serving mechanism during operation. The protective cover 215 and the fourth mounting seat 208 are connected in a detachable manner, so that the user can easily remove the protective cover 215 when necessary to perform maintenance and repair on the launch drive mechanism 206. In actual applications, the protective cover 215 can be set as a separate structure from the ball-serving mechanism 216 according to actual needs, or it can be set as an integrated structure of the protective cover 215 and the ball-serving mechanism 216.

[0053] Specifically, in some embodiments, participating Figure 8As shown, the ball holding mechanism 216 is separately provided from the protective cover 215, and the ball holding mechanism 216 is located on a side of the control module 213 away from the fourth mounting seat 208, and is firmly connected to the fourth mounting seat 208. Moreover, the ball holding mechanism 216 is hinged to a side of the ball striking mechanism 204 away from the launch drive mechanism 206, so that the ball holding mechanism 216 can provide necessary support and stability when the ball striking mechanism 204 performs a ball striking action.

[0081] Example 2: See Figure 7 The present invention also provides another ball launching device, which includes the various components described in the above embodiments. The difference is that the ball launching mechanism 2 in the launching device of this embodiment also includes a control module 213, and the control module 213 is electrically connected to the launching drive mechanism 206 and the rotating platform 209, respectively, for issuing launching related instructions.

[0082] Preferably, the control module 213 can be implemented by a single chip microcomputer or a control chip. Of course, a wireless communication module can also be provided in the control module 213, so that data communication can be performed with the intelligent mobile terminal through the wireless communication module to receive control instructions sent by the intelligent mobile terminal, such as a smart phone or iPad, including power on / off instructions, specific launch angle instructions, etc., and then forwarded to the corresponding launch drive mechanism 206 and the rotating platform 209, etc.

[0084] Specifically, the photographic component 202 is disposed on the outer surface of the housing 201 at the end along the direction of hitting the ball, and the shooting direction of the photographic component 202 is consistent with the direction of hitting the ball.

[0085] In some embodiments, the photographic component 202 has a range finding and shooting function, and can detect the position and distance of the athlete in real time. The control module 213 controls the launch drive mechanism 206 and the rotating platform 209 according to the photographic results, thereby accurately controlling the direction and distance of the basketball, simulating the passing situation in a real game, and improving the training effect. In other words, when the launch drive mechanism 206 receives an instruction from the control module 213, the driving force of the launch drive mechanism 206 is efficiently transmitted to the hitting mechanism 204 through the transmission mechanism, driving it to complete the hitting action at a set speed and strength, and accurately launching the basketball.

The display assembly not only improves the intelligence level of the launch mechanism, but also provides users with a more intuitive and convenient operation experience. Specifically, when in use, the display assembly 203 can receive and display the picture captured by the photography assembly 202 in real time, and can also receive various instructions and data from the control module 213, such as launch parameters, basketball status, etc., which improves the visualization of the launch process, provides users with more comprehensive and accurate launch information, and makes the entire launch process more controllable and efficient.

Specifically, when the sensor 214 detects that there is a ball on the hitting mechanism 204, and the photographic component 202 receives a user's ball request instruction from the control module 213 or a ball-serving instruction according to a preset mode, the sensor 214 sends a signal to the control module 213, and the control module 213 gives an instruction to start the launch drive mechanism 206, thereby driving the hitting mechanism 204 to launch the basketball to the user's location. Not only is the accuracy and efficiency of the launch improved, but also the launch failure caused by misoperation or missing basketball is effectively avoided.
