Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, in particular to a stepping motor driver with a protective structure. Background Art

[0002] A stepper motor driver is an actuator that converts electrical pulses into angular displacement. A stepper motor and a stepper motor driver form a stepper motor drive system. The performance of a stepper motor drive system depends not only on the performance of the stepper motor itself, but also on the quality of the stepper motor driver. The research on stepper motor drivers is almost carried out simultaneously with the research on stepper motors.

[0003] During the use of the motor, due to the diversity of usage scenarios, the motor will be used in different environments. Therefore, the motor driver will also produce certain vibrations in different scenarios, get water ingress or burn out due to long-term operation. Most of the existing drivers do not have sufficient protection structures, which affects their service life. Based on this, we propose a stepper motor driver with a protective structure.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a stepper motor driver with a protective structure, comprising a shell 1, a top plate 2 is fixedly installed on the top of the shell 1, a plurality of first air channels 11 are opened inside the top plate 2, the top of the first air channel 11 is connected with a plurality of second bends 21, the middle of the bottom of the first air channel 11 is connected with a first telescopic tube 13, a plurality of one-way limit valves 12 are arranged inside the first air channel 11, a bottom plate 4 is fixedly installed on the bottom of the shell 1, a plurality of second air channels 15 are opened inside the bottom of the bottom plate 4, the bottom of the second air channel 15 is connected with a plurality of first bends 20, a plurality of metal ring nets 16 are fixedly installed inside the second air channel 15, a second telescopic tube 19 is connected with the top of the second air channel 15, and the outer sides of the second bend 21 and the first bend 20 are A metal mesh plate 5 is fixedly installed through an annular groove, a protective layer 7 is fixedly installed inside the shell 1, a reinforcing support structure 8 is fixedly installed on the inner side of the protective layer 7, an inner frame 22 is fixedly installed on the inner side of the reinforcing support structure 8, a plurality of damping rods 9 are fixedly installed on the top and bottom of the inner cavity of the inner frame 22, a shock-absorbing spring 10 is sleeved on the outer side of the damping rod 9, a driver body 14 is fixedly installed on the opposite side of the damping rod 9, a connecting pipe 18 is connected to the top of the second telescopic tube 19, and the other end of the connecting pipe 18 is connected to a small air pump 17, which is fixedly installed inside the inner frame 22, a connecting socket 3 is provided on one side of the shell 1, a plurality of mounting holes 6 are opened inside the outer sides of the bottom plate 4 and the top plate 2, and the mounting holes 6 are rectangular, symmetrical and evenly distributed on the outer sides of the bottom plate 4 and the top plate 2.

[0020] The working principle of the above technical solution is as follows: when in use, the user installs the device at the use position through the mounting hole 6, ensuring that the bottom plate 4 is at the bottom and the top plate 2 is at the top, and then connects the motor control through the connecting socket 3. When in use, the small air pump 17 is started synchronously, and the airflow passes through the first bend 20 into the second airway 15. The design of the first bend 20 blocks the accumulated water and debris at the bottom, thereby increasing the protection. The airflow is guided into the second telescopic tube 19 through the second airway 15, and is pumped into the inner frame 22 through the second telescopic tube 19 and the connecting tube 18 through the small air pump 17. At this time, positive pressure is formed inside the inner frame 22, and the airflow is exported to the first airway 11 through the first telescopic tube 13, and is guided through the first airway 11 to the outside through the second bend 21.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the first air channels 11 are linearly and evenly arranged inside the top plate 2, and the second air channels 15 are linearly and evenly distributed inside the bottom plate 4. The opposite sides of the first air channels 11 and the second air channels 15 are connected through the air channels.

[0022] The metal mesh plate 5 and the first bend 20 and the second bend 21 can form a protection on the outside of the first air duct 11 and the second air duct 15 to prevent the entry of debris. The one-way action of the one-way limit valve 12 can prevent the entry of accumulated water. Multiple air inlet and outlet points reduce the risk of entry and balance the airflow guidance, so that the heat generated inside the inner frame 22 can be discharged in time, which is convenient for shrinking the air inlet and outlet, reducing the contact area, and ensuring that the air flow does not reduce the flow rate, so as to stabilize the heat dissipation efficiency and reduce the possibility of foreign matter entering.

[0023] In another embodiment, Figure 3 and Figure 4 As shown, the one-way limit valve 12 is located on the opposite side of the second bend 21 and the first telescopic tube 13 , and the metal ring mesh 16 is located on the opposite side of the first bend 20 and the second telescopic tube 19 .

[0024] The one-way limit valve 12 is convenient for limiting the flow direction of the airflow and reducing water ingress, and the multiple settings of the metal ring nets 16 ensure that when water droplets are sucked into the airflow, they can be blocked by the multiple metal ring nets 16 and flow out under gravity, thereby increasing the resistance to water entry and stabilizing the overall use effect.

[0025] In another embodiment, Figure 3 and Figure 4 As shown, the first telescopic tube 13 and the second telescopic tube 19 both movably penetrate the protective layer 7 and the inner frame 22 and extend to the interior of the inner frame 22 .

[0026] The telescopic buffer of the first telescopic tube 13 and the second telescopic tube 19 facilitates the airflow connection of the inner frame 22, and does not block the displacement after the displacement occurs, so it is convenient for coordinated operation without affecting the resistance, and the overall structure has a good use effect.

[0027] In another embodiment, Figure 3 and Figure 4 As shown, the protective layer 7 is located on opposite sides of the housing 1 and the inner frame 22 , and the reinforcement support structure 8 is located on four sides of the inner frame 22 .

[0028] By setting the protective layer 7 and the damping rod 9, the vibration of the motor and the harsh use environment during use can be buffered and protected by the protective layer 7 and the reinforced support structure 8, thereby increasing the protection strength in the working environment. At the same time, the elastic buffering of the damping rod 9 and the shock-absorbing spring 10 can make the driver body 14 always maintain a relative position, reduce large-scale movement, reduce the conduction of vibration, and increase the protection strength. This solution can be used in relatively harsh use environments, thereby increasing the protection strength and indirectly improving the service life.

[0029] In another embodiment, Figure 3 and Figure 4As shown, one end of the shock-absorbing spring 10 is fixedly mounted inside the inner frame 22, and the other end of the shock-absorbing spring 10 is fixedly mounted on the outside of the driver body 14. The damping rod 9 and the shock-absorbing spring 10 are symmetrically distributed in a rectangular shape on opposite sides of the inner frame 22 and the driver body 14, and the inner side of the connecting socket 3 is electrically connected to the connecting end of the driver body 14 through a wire.

[0030] The shock-absorbing spring 10 and the damping rod 9 facilitate stabilizing the driver body 14 in the use position, avoiding large vibrations, reducing the conduction of vibrations, making the overall structure stable, and facilitating increased protection. At the same time, the driver body 14 is connected to the motor via the connecting socket 3, and the output end of the driver body 14 is electrically connected to the input end of the small air pump 17 via a wire, so as to facilitate powering it after startup.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
