Detailed Description

The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Please refer to fig. 1 to 18 in combination, which illustrate a skipping rope handle provided by an embodiment of the present invention, wherein the skipping rope handle includes a key switch structure thereof. Wherein, fig. 1 to 3 show that the skipping rope handle comprises a handle main body 1, a key component 2 and a rope end rotating shaft component 3.

In the present specification, the front-rear relationship is defined by the cord end rotation shaft assembly 3 being located in front of the key assembly 2, that is, the upper end structure in fig. 1 to 3 is shown at the rear, and the lower end structure is shown at the front, which are also described herein.

Fig. 1 shows a state of the handle for a skipping rope in which the key assembly 2 is plugged in the rear end opening of the inner cavity of the handle body 1.

Fig. 2 shows another state of the jump cord handle in which the main body portion of key assembly 2 is taken out from the rear end opening of the inner cavity of handle body 1.

Fig. 3 shows the exploded structure of the rope skipping handle, and it can be seen that the rope end rotating shaft assembly 3 comprises a bearing seat 31, a bearing 32, a rope end rotating shaft 33 and a cover 34.

The rear end of the handle body 1 is provided with a section of chamfer angle to form a contraction part. The rear end face of the handle body 1 has an end opening (not labeled) similar to an ellipse. That is, the handle body 1 has a chamfered contraction portion (not shown) at the rear end thereof, and the opening at the rear end of the handle body 1 is formed in an elliptical shape (in a front view, see fig. 2).

As can be seen from fig. 1 to 3, the key switch structure of the skipping rope handle provided in this embodiment is disposed on the handle main body 1 of the skipping rope handle, wherein fig. 3 shows that the key switch structure includes:

a key assembly 2, wherein the key assembly 2 is used for pressing a circuit switch 41 (refer to the following contents) in the inner cavity of the handle body 1; the key assembly 2 comprises a key plug 21 and a key base 22;

the key plug 21 includes a connection portion 2111, and the connection portion 2111 is movably connected to the key base 22 (refer to the following contents);

at least part of the structure of the key plug 21 is flexible, so that the key plug 21 can be plugged in and taken out conveniently from the rear end opening of the inner cavity of the handle body 1;

the key base 22 has a base hole 2220, please refer to fig. 11 and 12 in combination;

the key plug 21 has a plugged state for plugging the port of the inner cavity of the handle body 1, as shown in fig. 1, in the plugged state, the rear surface of the key plug 21 seals the port of the inner cavity of the handle body 1;

the key plug 21 has a removal state of being removed from the port of the inner cavity of the handle body 1, as shown in fig. 2, in the removal state, the connection portion 2111 keeps movably connected with the key seat 22 in the inner cavity of the handle body 1; in the removed state, the port and the seat hole 2220 of the internal cavity of the handle body 1 expose the charging port 42 in the internal cavity of the handle body 1.

As can be seen from the above, in the key switch structure of the skipping rope handle provided in this embodiment, the key plug 21 can be conveniently taken out from the inner cavity of the handle body 1. When the key plug 21 is taken out, the connecting portion 2111 is still connected to the inner cavity of the handle body 1, so as to prevent the key plug 21 from falling or losing. In the state where key plug 21 is removed, charging port 42 in the inner cavity of handle body 1 is exposed through seat hole 2220 of key seat 22, and at this time, charging can be performed easily. When the key plug 21 is plugged into the rear opening of the inner cavity of the handle body 1 (i.e. when the key plug 21 is plugged into the groove of the key base 22), the key plug 21 can seal the rear opening of the inner cavity of the handle body 1, so as to protect the circuit structure inside the handle body 1. Meanwhile, when the key plug 21 is plugged into the rear end opening of the inner cavity of the handle body 1, the key base 22 and the key plug 21 are matched to form the key assembly 2, which can also be used as a pressing structure for the circuit switch 41, and the circuit switch 41 is controlled along with the pressing of the key plug 21 by a human hand. Therefore, the whole key switch structure realizes the integration of multiple functions, and has reasonable and ingenious structural design, convenient use and durability.

In this embodiment, the moving direction formed by the movable connection may be an axial direction of the handle body 1, and this direction is also a direction in which the user can press and release the key plug 21 (the release may include a natural rebound of the circuit switch after pressing). Wherein the circuit switch 41 may be a tact switch that springs back a small distance each time it is pressed when the pressure is removed, wherein the spring back distance for opening and closing the two different presses is typically slightly different. In other embodiments, other switches may be used, and the present invention is not limited thereto.

In this embodiment, referring to the subsequent content (see fig. 11 and 12), the front view shape of the seat hole 2220 may be a racetrack shape, which is the same as the front view shape of the charging interface 42 on the circuit board 4, and the charging interface 42 may be a currently commonly used round hole charging interface, such as a USB Type-C interface.

Fig. 3 shows that the key plug 21 includes a key cap 211 and a key body 212, and the key plug 21 and the key base 22 are commonly included in the key assembly 2.

Fig. 3 shows that connecting portion 2111 is part of key cap 211. With further reference to fig. 4, 5, and 6, connecting portion 2111 extends downward from an edge of keycap 211, connecting portion 2111 having a chute 21110.

Fig. 4 shows that key cap 211 has cap holes 2110, and cap holes 2110 penetrate through inner and outer surfaces of key cap 211. The key cap 211 also has side edges 2112, the side edges 2112 enclosing a recess (not labeled) of the key cap 211 for the assembly of the key body 212, the bottom of the recess being penetrated by a cap hole 2110.

In this embodiment, the key cap 211 is a silica gel structure, which is a good flexible structure, so that the key cap 211 can be plugged (plugged and taken out) more conveniently, that is, the whole key plug 21 can be plugged conveniently. It should be noted that in other embodiments, the key cap may also be a flexible structure made of other materials.

Referring to fig. 5, and other corresponding angle views, keycap 211 has corner notch 2113. The corner notch 2113 is designed to facilitate removal of the key plug 21 from the port in the interior cavity of the handle body 1.

Referring to fig. 6, it is shown that a portion of the outer side surface of the side edge 2112 is curved and another portion of the outer side surface is flat, and the connecting portion 2111 is located at a position other than the outer side surface of the side edge 2112 which is flat. In the angle shown in fig. 6, the connecting portion 2111 is like a tail extending downward from the edge of the key cap 211, and the sliding groove 21110 therein is also a section of groove extending upward and downward.

Referring to fig. 7, the key body 212 has a boss 2121 having a cylindrical shape, and the outer surface of the boss 2121 has a switch icon.

Referring to fig. 8, a concave structure 2120 is formed behind the boss 2121 of the key body 212, and the concave structure 2120 is also circular and concave.

Referring to fig. 9 and 10, when the key body 212 and the key cap 211 are assembled together, the boss 2121 is fitted in the cap hole 2110 to become the key plug 21.

Referring to fig. 9, 10 and the previous figures, in the plugged state, in the present embodiment, the outer surface of the boss 2121 seals the cap hole 2110, and the outer surface of the boss 2121 and the outer surface of the cap hole 2110 form the back surface of the key plug 21. The rear surface of the key plug 21 seals the port of the inner cavity of the handle body 1, i.e. the outer surface of the key cap 211 and the surface of the boss 2121 of the key body 212 are combined together and exposed to the outside, and the plugged state is as shown in fig. 1.

Referring to fig. 11 and 12, the key base 22 has a protrusion 2222. As mentioned above, the connecting portion 2111 has the sliding slot 21110, and the protrusion 2222 is snapped into the sliding slot 21110, and the sliding slot 21110 can slide while being limited by the protrusion 2222, so as to achieve the movable connection, which can be referred to in conjunction with fig. 15 and 2. The connection portion 2111 is part of the key cap 211, and therefore, it also has flexibility, thereby making the corresponding movable connection more flexible.

That is, protrusions 2222 snap into slots 21110, so that even when key base 22 is stationary, the entire key assembly 2 can move back and forth, substantially within the dimension of slots 21110 minus protrusions 2222, ensuring the articulation. Meanwhile, the key base 22 itself can move within a distance range from the front to the back, which further increases the moving range of the movable connection, thereby further ensuring that the plugging and removing operations of the key plug 21 have sufficient moving margin, and therefore, it can be known that the movable connection realized by the cooperation of the protrusions 2222 and the sliding slots 21110 can enable the key plug 21 to be plugged and removed more conveniently.

Fig. 11 also shows that the key base 22 includes a side wall 221, an inner partition 222, and a pressing portion 2221, and the outer surface of the side wall 221 has a curved portion and a flat portion (not labeled), so that the front shape of the side wall 221 is a quasi-elliptical shape having a straight edge, and the protrusion 2222 is just the flat portion on the outer surface of the side wall 221.

Referring to fig. 11, in the present embodiment, the pressing portion 2221 is located on the front surface of the inner partition 222. The pressing portion 2221 has a rectangular parallelepiped convex shape in the present embodiment, and may have other shapes in other embodiments. The pressing portion 2221 can be used to achieve a better pressing operation of the circuit switch 41.

In the present embodiment, in the plugged state, the pressing portion 2221 abuts against the switch contact of the circuit switch 41, and referring to fig. 18, the section of fig. 18 shows that the pressing portion 2221 abuts against the switch contact of the circuit switch 41.

In this embodiment, the pressing portion 2221 abuts against the switch contact of the circuit switch 41 in the axial direction of the handle body 1. Note that, when the key plug 21 is removed, the pressing portion 2221 may be still held against the switch contact of the circuit switch 41. In other embodiments, when the key plug 21 is removed, the pressing portion 2221 does not have to abut against the switch contact of the circuit switch 41, and the pressing portion and the circuit switch can be separated from each other.

Fig. 13, 14 and 15 show the structure of the key assembly 2 at three different angles for a better understanding of the structure of the key assembly 2. After the three structures included in the key assembly 2 are assembled, in the plugged state, they are in the form shown in fig. 13 to 15, and they are an integrated body.

Fig. 16 shows a state in which protective housings (not labeled) including an upper portion 6 and a lower portion 5 are put together to protect the circuit board 4, and the circuit board 4 is located in an inner space surrounded by the upper portion 6 and the lower portion 5.

Fig. 17 shows that the circuit board 4 has two indicator lights 43 (in other embodiments, one indicator light may be used), and the indicator lights 43 are disposed at the rear end of the circuit board 4. In this embodiment, the key base 22 is configured to be a light-transmitting structure (i.e., the key base 22 is made of a light-transmitting material), and similarly, the key body 212 is configured to be a light-transmitting structure. This configuration is to better fit the indicator light 43. Because, in the case of the indicator light 43, the key base 22 and the key body 212 are both made of a light-transmitting material, which is beneficial for the light of the indicator light 43 to better penetrate through the whole key assembly 2, so that the corresponding required indication state (for example, the state of the skipping rope counting in progress, or the different states of the electric quantity, etc.) is displayed to the user through the outer surface (rear surface) of the key assembly 2.

The indicator 43 may be an LED lamp, may be a single color, may be different colors, may have a single brightness, or may have different brightnesses.
