Description

Technical Field

[0001] The utility model belongs to the field of modular motors, and in particular relates to an anti-miscontact plug of a modular motor. Background Art

[0002] With the rapid development of my country's economy, a large number of equipment using engines have gradually begun to develop in the direction of electrification, such as new energy vehicles and other mobile devices. However, since the position of mobile devices constantly changes during use, it is difficult to power them continuously and uninterruptedly. Therefore, during use, it is usually necessary to connect an external battery pack to the motor to ensure that it can be used normally for a period of time. However, since the battery pack cannot be removed, it needs to be recharged when it is out of power.

[0003] Based on the above problems, the prior art provides a motor with a detachable battery pack. During use, only the fully charged battery pack needs to be replaced with the exhausted battery pack, thereby further reducing the impact of the dead battery pack on the battery life of the device. However, due to the need to repeatedly plug and unplug the battery pack, damage is very likely to occur at the connection between the battery pack and the module motor during the installation process, resulting in the device being unable to be used normally. In addition, since the connection position is directly exposed to the outside, it is very likely to be short-circuited by water, posing a safety hazard. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose an anti-mistouch plug for a module motor. The technical problem to be solved by the utility model is: how to improve the service life and safety of the module motor.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a plug for preventing accidental touch of a modular motor, comprising a shell, a detachable battery pack and a motor, a battery compartment for accommodating the battery pack is provided in the shell, a plug electrically connected to the motor is provided at the bottom of the battery compartment, and contacts are provided on the plug, characterized in that elastic components that can make the battery pack pop out are provided on both sides of the plug, a baffle that can move up and down is fixedly connected to the elastic component, the baffle is located between the battery pack and the elastic component, and the contact can pass through the baffle to be electrically connected to the battery pack.

[0006] The present application is a plug for preventing accidental touch of a module motor, which mainly installs a battery pack in a battery compartment of the module motor and electrically connects the battery pack to the motor through contacts on the plug. When replacing the battery, the battery pack needs to be pushed out through elastic components located on both sides of the plug, wherein a baffle that can move up and down is fixedly connected to the elastic component. When installing the battery pack, the baffle is pressed downward by the influence of the battery pack. While the baffle moves downward, the contact passes through the baffle and is electrically connected to the battery pack. Since the baffle is fixed on the elastic component and moves up and down under the influence of gravity, it can prevent water from contacting the contacts in a non-use environment, thereby improving the safety of use. In addition, due to the presence of the baffle, the contacts in the plug are prevented from bending during the installation of the battery pack, thereby improving the service life.

[0007] In the anti-miscontact plug of the module motor, the baffle is provided with a hole corresponding to the contact, and the cross section of the hole is a trapezoid with a larger bottom and a smaller top. The contact passes through the hole and is electrically connected to the battery pack. Since the cross section of the hole is a square with a larger bottom and a smaller top, it can not only guide and correct the end of the contact during use, thereby improving the service life, but also prevent water from entering the plug and contacting the contact to cause a short circuit, thereby improving the safety of use.

[0008] In the anti-miscontact plug of the module motor, the plug also includes limit strips on both sides of the contact, and the baffle is also provided with a limit slot for the limit strip to pass through, and the upper end surface of the limit strip is flush with the upper end surface of the contact. Since the limit strips are provided on both sides of the contact, and the upper end surface of the limit strip is higher than the upper end surface of the contact, the battery pack can be limited at the same time during the installation process, avoiding the back and forth shaking of the baffle plate and causing the contact and the hole of the baffle plate to be misaligned, thereby improving the service life.

[0009] In the anti-accidental-touch plug of the above-mentioned module motor, the battery pack includes a shell and an interface that cooperates with the plug. The interface is fixedly connected to the shell, and a limit groove is provided between the outer side of the interface and the shell, and the limit strip passes through the limit groove and cooperates with the limit groove.

[0010] In the anti-mistouch plug of the module motor, the baffle is provided with a positioning boss that matches with the top of the elastic component, and the two sides of the interface of the battery pack are provided with concave surfaces that abut against the positioning boss.

[0011] In the anti-miscontact plug of the module motor, a buckle is provided on the side of the battery compartment. When the battery pack is inserted into the battery compartment, the buckle is connected with the clamping part on one side of the battery pack. The buckle prevents the battery pack from being separated or having poor contact due to the elastic component during use, thereby improving the user experience.

[0012] In the anti-mis-touch plug of the module motor, the two side walls of the battery pack are provided with positioning slots that match the battery compartment, the slots include narrow slots and wide slots, and the two sides of the battery compartment are provided with wide ribs and narrow ribs that match the positioning slots. By providing narrow slots and wide slots on the battery pack and making them match the battery compartment, it is possible to further avoid damage to the device due to incorrect installation.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. This application mainly sets a baffle between the battery pack and the elastic component, which can move back and forth with the elastic component, and opens holes on the baffle for contacts to pass through to ensure the stability of the electrical connection between the battery pack and the motor.

[0015] 2. Make the contact pass through the hole with a trapezoidal cross-section, and then electrically connect with the interface on the battery pack, and set limit strips flush with the contacts on both sides of the contacts, so that the limit strips cooperate with the limit grooves on the baffle, so that when installing the battery pack, it can further prevent the baffle from shaking back and forth and causing the hole and contact to be misaligned, thereby improving the service life of the interface and the contact.

[0023] like Figure 1As shown, the module motor 3 includes a motor 3 located at the front end, a shell 1 located on both sides of the motor 3 and a battery compartment 1a located between the two shells 1, an elastic component 5 and a plug 4 are provided at the bottom of the battery compartment 1a, wherein the elastic component 5 is located on both sides of the plug 4, and the upper covers of the two elastic components 5 are provided with baffles 6, and the baffle 6 is provided with a positioning boss 6c formed in cooperation with the elastic component 5, and the elastic component 5 and the baffle 6 are fixedly connected through the positioning boss 6c, and a limiting groove 2d and a hole 6a for the contact 4a on the plug 4 and the limiting strip 4b to penetrate 6a are provided between the two positioning bosses 6c, wherein the cross-section of the hole 6a is a trapezoidal shape with a larger bottom and a smaller top, and a buckle 7 is fixedly connected to the top of the battery compartment 1a to prevent the battery pack 2 from popping out during use.

[0024] like Figure 2 and Figure 3 As shown, the battery compartment 1a is located at the rear end of the motor 3, the elastic component 5 and the plug 4 are both located at the bottom of the battery compartment 1a, and a baffle 6 is fixedly connected to the top head 5a of the elastic component 5. The baffle 6 covers the plug 4, and makes the contact 4a and the limit strip 4b in the plug 4 relatively arranged with the limit groove 2d and the contact 4a on the baffle 6, wherein the hole 6a on the baffle 6 is a trapezoidal shape with a larger bottom and a smaller top. When the battery pack 2 is installed in the battery compartment 1a, the limit strip 4b passes through the limit hole 6b on the baffle 6 and cooperates with the limit groove 2d at the bottom of the battery pack 2, and makes the contact 4a in the plug 4 cooperate with the interface 2b, thereby completing the electrical connection between the motor 3 and the battery pack 2, and the side wall of the battery compartment 1a is provided with a wide rib 1a1 and a narrow rib 1a2.

[0025] like Figure 4 As shown, the battery pack 2 includes a positioning slot 2c, a shell 2a and an interface 2b located on both sides of the battery pack 2, wherein the positioning slot 2c includes a wide slot 2c2 and a narrow slot 2c1 that match the battery compartment 1a, and a concave surface 2a1 that matches the positioning boss 6c is provided on both sides of the interface 2b, and the shell 2a and the interface 2b cooperate to form a limiting slot 2d.

[0026] In summary, the working principle of the present application is as follows: a battery compartment 1a is provided at the rear end of the motor 3 for easy removal of the battery pack 2, and the motor 3 and the battery compartment 1a are covered in the shell 1 to form a module motor 3, so that the designer only needs to select different motor 3 models according to different torque requirements, which reduces the design difficulty, and during use, since the motor 3 is electrically connected to the detachable battery pack 2 in the battery compartment 1a, the dead battery pack 2 can be replaced with the fully charged battery pack 2 during use, so as to further improve the endurance of the motor 3, and an elastic component 5 is provided at the bottom of the battery compartment 1a, and the top head on the elastic component 5a is abutted against the concave surface 2a1 at the bottom of the battery pack 2 through the positioning boss 6c on the baffle 6, and a buckle 7 is provided at the upper end of the battery compartment 1a, so as to prevent the elastic component 5 from ejecting the battery pack 2 during use, and the wide ribs 1a1 and the narrow ribs 1a2 of the battery compartment are matched with the narrow groove and the wide groove to avoid damage to the contacts due to incorrect installation.

[0027] The battery pack 2 is plugged into the plug 4 at the bottom of the battery compartment 1a through the interface 2b at the bottom, and a baffle 6 is arranged between the battery pack 2 and the plug 4 and the elastic components 5 on both sides of the plug 4, and a limiting hole 6b and a hole 6a are arranged on the baffle 6, so that the contact 4a in the plug 4 can be electrically connected to the contact piece of the interface 2b, and the limiting strip 4b in the plug 4 cooperates with the limiting groove 2d between the interface 2b and the shell 2a to avoid poor contact caused by shaking of the battery pack 2 during use, and because the baffle 6 is fixedly connected to the top head 5a on the elastic component 5 through the positioning boss 6c, Thereby, when the battery pack 2 is installed or removed, the baffle 6 can move up and down along with whether the battery pack 2 is removed or not. Since the cross-section of the hole 6a for the contact 4a to pass through is a trapezoid with a larger bottom and a smaller top, the contact 4a can be guided during the passage to avoid the contact 4a from being misaligned and broken. When water enters, the risk of short circuit caused by contact between water and contact 4a can be further reduced due to the tension of the water. Since the limit strip 4b is flush with the upper end surface of the contact 4a, the contact 4a is prevented from being misaligned with the hole 6a during the downward movement of the baffle 6, thereby avoiding damage to the contact 4a.
