[0047] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0048] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0049] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0050] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0052] The transmission assembly 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0053] like Figures 1 to 18 As shown, the transmission assembly 100 according to an embodiment of this application includes a first movable member 10, a mating member 20, and a second movable member 30.

[0054] Specifically, the first movable member 10 is movable along a first direction and a second direction, the first direction being opposite to the second direction. The mating member 20 is movably disposed between the first movable member 10 and the second position 24 and the second position 25. The second movable member 30 is movably disposed on one side of the first movable member 10. The second movable member 30 is provided with a mating part 31 that mates with the mating member 20.

[0055] When the first movable member 10 moves in the first direction, the cooperating member 20 is in the first position 24, the cooperating member 20 cooperates with the cooperating part 31 and drives the second movable member 30 to move. When the first movable member 10 moves in the second direction, the second movable member 30 is static, the cooperating member 20 is in the second position 25, or the cooperating member 20 is driven by the cooperating part 31 from the first position 24 to the second position 25.

[0056] In other words, the transmission assembly 100 according to the embodiments of the present application mainly comprises the first movable member 10, the cooperating member 20 and the second movable member 30. The cooperating member 20 is movably arranged on the first movable member 10, and can move with the first movable member 10 and also can move by itself. The cooperating part 31 is arranged on the second movable member 30, and can move with the second movable member 30. During the movement of the first movable member 10 in the first direction, the cooperating member 20 can cooperate with the cooperating part 31, for example, is clamped, so that the cooperating member 20 can drive the cooperating part 31 to move, and further drives the second movable member 30 to move through the cooperating part 31. During the movement of the first movable member 10 in the second direction, the cooperating member 20 can avoid the cooperating part 31, the cooperating member 20 does not exert force on the cooperating part 31 or the counterforce of the cooperating member 20 on the cooperating part 31 drives the cooperating member 20 to avoid the cooperating part 31, so that the cooperating part 31 is static, and further the second movable member 30 is in a static state.

[0057] The first direction and the second direction are oppositely arranged, that is, the first movable member 10 can move in the first direction or the second direction which are oppositely arranged, for example, the first direction is left, and the second direction is right; or the first direction is up, and the second direction is down, and the like, which are not limited herein.

[0058] Before the first movable member 10 moves in the first direction, the cooperating member 20 on the first movable member 10 can be in the first position 24 or moves from the second position 25 to the first position 24. When the cooperating member 20 is in the first position 24, at least a part of the cooperating part 31 is in front of the cooperating member 20 in the first direction, which hinders the cooperating member 20 to continuously move in the first direction. When the cooperating member 20 continuously moves in the first direction, the cooperating member 20 can exert force on the cooperating part 31 which is sufficient to drive the cooperating part 31 to move, and further drives the second movable member 30 to move through the cooperating part 31.

[0059] When the first movable member 10 moves along the second direction, the engaging member 31 can have been moved from the first position 24 to the second position 25, or can be moved from the first position 24 to the second position 25. When the engaging member 31 is at the second position 25, the engaging member 31 can be away from the engaging member 20 in the second direction, and will not hinder the engaging member 20 from moving forward along the second direction, so that the engaging member 20 will not move the engaging member 31, i.e. the second movable member 30 is in a static state.

[0060] When the first movable member 10 moves along the second direction, the engaging member 20 can always be at the second position 25, or can be moved from the first position 24 to the second position 25 under the action of the reaction force of the engaging member 20 on the engaging member 31. That is, when the first movable member 10 moves along the second direction, the engaging member 20 can be moved from the first position 24 to the second position 25 under the action of the engaging member 31, or can be moved from the first position 24 to the second position 25 under the action of its own gravity, or can be moved from the first position 24 to the second position 25 under the action of other parts such as a return spring, as long as the structure and design that the second movable member 30 remains static when the first movable member 10 moves along the second direction are within the protection scope of the present application.

[0061] The position and movement state of the engaging member 20 when the first movable member 10 moves along the second direction will be described below.

[0062] Case One

[0063] When the movement of the first movable member 10 along the first direction ends, the engaging member 20 can be moved from the first position 24 to the second position 25 under the action of its own gravity or other parts. In this way, the engaging member 20 can be at the second position 25 before the first movable member 10 starts to move along the second direction. Thus, when the first movable member 10 moves along the second direction, the engaging member 20 can always be at the second position 25, and will not hinder the engaging member 20 from moving forward along the second direction.

[0064] Case Two

[0065] When the first movable element 10 stops moving in the first direction, the cooperating element 20 is in the first position 24, i.e. before the first movable element 10 moves in the second direction, the cooperating element 20 is in the first position 24. Thus, when the first movable element 10 moves in the second direction, the cooperating part 31 is in front of the cooperating element 20 in the second direction first, and when the cooperating element 20 moves to abut against the cooperating part 31, the cooperating element 20 exerts a force on the cooperating part 31, and the cooperating part 31 is subjected to a reaction force of the cooperating element 20, and the cooperating element 20 can move from the first position 24 to the second position 25 under the action of the reaction force of the cooperating element 20 on the cooperating part 31. It should be noted that when the first movable element 10 moves in the second direction, the force exerted by the cooperating element 20 on the cooperating part 31 cannot drive the second movable element 30 to move, and the second movable element 30 is in a stationary state, and at this time the reaction force of the cooperating part 31 drives the cooperating element 20 to move to the second position 25.

[0066] That is, when the cooperating element 20 is in the first position 24, the cooperating element 20 can cooperate with the cooperating part 31, and the first movable element 10 moving in the first direction can drive the second movable element 30 to move. When the cooperating element 20 moves from the first position 24 to the second position 25 by its own gravity or cooperation with the cooperating part 31, the first movable element 10 moving in the second direction cannot drive the second movable element 30 to move.

[0067] The working process of the first movable element 10 of one embodiment of the application will be described below.

[0068] First, when the first movable element 10 moves in the first direction, the cooperating element 20 is in the first position 24; then, when the first movable element 10 moves in the second direction or before moving, the cooperating element 20 moves from the first position 24 to the second position 25; then, before the first movable element 10 repeatedly moves in the first direction, the cooperating element 20 moves from the second position 25 to the first position 24, so that when the first movable element 10 moves in the first direction, the cooperating element 20 is in the first position 24. This cycle can realize the one-way movement of the second movable element 30.

[0069] That is, in use, the first movable element 10 can be first driven to move in the first direction to drive the second movable element 30 to move, and then the first movable element 10 can be driven to move in the second direction, and at this time the second movable element 30 is stationary. The first movable element 10 can be driven to move in the first direction repeatedly, and thus the one-way movement of the first movable element 10 can provide driving force for the second movable element 30.

[0070] Thus, according to the transmission assembly 100 of the embodiment of the present application, by adopting the movable cooperating part 20, the first movable part 10 can drive the second movable part 30 to move when the first movable part 10 moves in the first direction, and the second movable part 30 remains stationary when the first movable part 10 moves in the second direction, that is, the first movable part 10 realizes the function of providing driving force in one direction. The transmission assembly 100 of the present application has the advantages of being simple and convenient, and suitable for mass production.

[0071] According to one embodiment of the present application, one side of the first movable part 10 is provided with a mounting portion 40, the first end of the cooperating part 20 is movably connected with the mounting portion 40, and the second end of the cooperating part 20 is rotatable about the first end of the cooperating part 20. That is, the cooperating part 20 is mounted through the mounting portion 40.

[0072] The working principle of the mounting portion 40 and the cooperating part 20 of one embodiment of the present application will be described below.

[0073] The mounting portion 40 is arranged on the upper surface of the first movable part 10, and the lower end of the cooperating part 20 is mounted on the mounting portion 40 and rotatably connected with the mounting portion 40. The upper end of the cooperating part 20 is rotatable clockwise or counterclockwise about the lower end of the cooperating part 20. When the first movable part 10 moves to the left, the lower end of the cooperating part 20 can move to the left synchronously with the first movable part 10. Similarly, when the first movable part 10 moves to the right, the lower end of the cooperating part 20 can also move to the right synchronously with the second movable part 30. In addition, the upper end of the cooperating part 20 can rotate relative to the lower end of the cooperating part 20.

[0074] In the embodiment, by mounting the first end of the cooperating part 20 on the mounting portion 40, the mounting difficulty of the cooperating part 20 can be simplified. The mounting portion 40 and the first movable part 10 can be an integrally formed part or a detachable connecting part, which is not limited herein. Rotatably connecting the cooperating part 20 with the mounting portion 40 can make the cooperating part 20 rotate to the first position 24 and push the cooperating part 31 when the first movable part 10 moves in the first direction, and make the cooperating part 20 rotate in the opposite direction to avoid the cooperating part 31 when the first movable part 10 moves in the second direction, which is beneficial to the first movable part 10 to provide pushing force in one direction.

[0075] Alternatively, the mounting portion 40 and the first end of the cooperating part 20 can be pivotably connected through a rotating shaft 90, for example, the mounting portion 40 and the first end of the cooperating part 20 are respectively provided with mounting holes 45, and the rotating shaft 90 is inserted into the mounting holes 45, and the upper end of the cooperating part 20 can rotate about the axis of the rotating shaft 90.

[0076] Further, the mounting portion 40 protrudes from the surface of the first movable piece 10, for example, is higher than the upper surface of the first movable piece 10. When the first end of the cooperating piece 20 is connected with the mounting portion 40, the first end of the cooperating piece 20 has a certain height, that is, has a certain distance from the upper surface of the first movable piece 10, so that when the second end of the cooperating piece 20 rotates, the cooperating piece 20 and the upper surface of the first movable piece 10 do not interfere with each other. That is, in the present application, by making the mounting portion 40 protrude from the surface of the first movable piece 10, the rotation angle and the movement range of the cooperating piece 20 are expanded, and the distance between the first movable piece 10 and the second movable piece 30 is reduced. The length of the cooperating piece 20 does not need to be designed to be too long, so that the overall structure of the transmission assembly 100 is more compact.

[0077] In the present embodiment, by providing the mounting portion 40 on the first movable piece 10, not only the installation of the cooperating piece 20 can be realized, but also the rotation of the cooperating piece 20 and the control of the rotation angle are facilitated.

[0078] According to one embodiment of the present application, the cooperating piece 20 and the mounting portion 40 are respectively a plurality of mounting portions 40, and the adjacent two mounting portions 40 are spaced apart to form a receiving groove 41. When the cooperating piece 20 is located at the first position 24, a first included angle a is formed between one side surface of the cooperating piece 20 and the bottom surface of the receiving groove 41. When the cooperating piece 20 is located at the second position 25, a second included angle β is formed between the side surface of the cooperating piece 20 and the bottom surface of the receiving groove 41, and the angle of the second included angle β is smaller than the angle of the first included angle a.

[0079] For example, the first movable piece 10 extends in the horizontal direction and in the left-right direction, a plurality of mounting portions 40 are provided on the first movable piece 10, and the cooperating piece 20 is installed on each mounting portion 40. The plurality of mounting portions 40 are distributed in the left-right direction with a gap therebetween, and the gap between the adjacent two mounting portions 40 can serve as the receiving groove 41.

[0080] The two mounting portions 40 can constitute a repeating unit, and for the convenience of description, the two mounting portions 40 are divided into a left mounting portion 42 and a right mounting portion 43. The receiving groove 41 is defined between the left mounting portion 42 and the right mounting portion 43. The number of the cooperating pieces 20 corresponding to the repeating unit can also be two, and the two cooperating pieces 20 are divided into a left cooperating piece 21 and a right cooperating piece 22.

[0081] The lower end of the left engaging member 21 is mounted on the left mounting portion 42, and the upper end of the left engaging member 21 is rotatable clockwise or counterclockwise. The lower end of the right engaging member 22 is mounted on the right mounting portion 43, and the upper end of the right engaging member 22 is also rotatable clockwise or counterclockwise. When the left engaging member 21 is located at the first position 24, there is a first included angle a between the right side surface of the left engaging member 21 and the bottom surface of the accommodating groove 41. When the upper end of the left engaging member 21 is moved clockwise to the second position 25, there is a second included angle β between the right side surface of the left engaging member 21 and the bottom surface of the accommodating groove 41. When the length of the left engaging member 21 is a fixed value, the distance between the upper end of the left engaging member 21 and the engaging portion 31 of the second movable member 30 changes constantly when the upper end of the left engaging member 21 is rotated. The distance between the upper end of the left engaging member 21 located at the first position 24 and the engaging portion 31 of the second movable member 30 is S1, and the distance between the upper end of the left engaging member 21 located at the second position 25 and the engaging portion 31 of the second movable member 30 is S2. Since the second included angle β is smaller than the first included angle a, S1 < S2, which is beneficial to control the second movable member 30 to be in different states respectively when the first movable member 10 is moved in the first direction and the second direction.

[0082] In the present embodiment, by defining the accommodating groove 41 between two adjacent mounting portions 40, the transmission assembly 100 can have a space for accommodating the engaging member 20, avoiding the movement of the previous engaging member 20 being interfered by the next engaging member 20 or the next mounting portion 40, etc., and expanding the movement range of the engaging member 20. In addition, by providing the accommodating groove 41, it is also beneficial to realize the movement of the engaging member 20 from the first position 24 to the second position 25.

[0083] According to one embodiment of the present application, the engaging member 20 is a first engaging tooth, and the engaging portion 31 is a second engaging tooth. When the engaging member 20 is located at the first position 24, the first engaging tooth and the second engaging tooth can be engaged, so as to realize the rotation of the second engaging tooth driven by the first engaging tooth when the first movable member 10 is moved in the first direction.

[0084] In some specific embodiments of the present application, the first movable member 10 and the engaging member 20 form a rack, i.e., the engaging member 20 is a first engaging tooth provided on the rack. The second movable member 30 is a gear, i.e., the engaging portion 31 is a second engaging tooth provided on the gear. The gear is movable in the clockwise or counterclockwise direction around its axis. For example, the rack extends in the horizontal direction and in the left-right direction, the gear is located above the rack, the axis of the gear extends in the horizontal direction, and the axis of the gear can have an included angle with the extending direction of the rack, which can be 90°, etc.

[0085] For the prior art rack and pinion transmission structure, the movement direction of the rack is the movement direction provided to the pinion, and only a limited length of drive can be provided, for example, limited by the length of the rack. The transmission assembly 100 of the present application can repeatedly push the rack to provide the same direction power, and in each back and forth movement of the rack, only the first direction stroke can provide the same direction power to the pinion, which can correspond to the application scene of multi-function and multi-station, and can continuously provide the pushing force to the pinion.

[0086] In the present embodiment, by adopting the rack and pinion cooperation, when the first movable member 10 moves in the first direction, the linear motion of the rack can be converted into the rotation of the pinion, and when the first movable member 10 moves in the second direction, the linear motion of the rack will not cause the rotation of the pinion.

[0087] According to an embodiment of the present application, one side of the first movable member 10 is further provided with a limiting portion 50, and the limiting portion 50 cooperates with the cooperating member 20 to limit the rotation angle of the cooperating member 20. Specifically, the limiting portion 50 can limit the rotation angle of the cooperating member 20 when the first movable member 10 moves in the first direction, so that the cooperating member 20 does not avoid the cooperating portion 31, which is beneficial to the movement of the cooperating portion 31 driven by the cooperating member 20. When the first movable member 10 moves in the second direction, the limiting portion 50 can also limit the rotation angle of the cooperating member 20, so that the cooperating member 20 can avoid the cooperating portion 31, which is beneficial to the static state of the cooperating portion 31.

[0088] Further, the limiting portion 50 is arranged on the mounting portion 40. By arranging the limiting portion 50 on the mounting portion 40, the installation of the limiting portion 50 is facilitated. Further, the limiting portion 50, the mounting portion 40 and the first movable member 10 are integrally formed, which has the advantage of facilitating the processing and production.

[0089] Further, as shown in FIG. 1, the first movable member 10 is provided with a mounting portion 40, and the cooperating member 20 is arranged on the mounting portion 40. Figure 8 and Figure 9As shown, the limiting part 50 is a strip-shaped member, and the limiting part 50 as a whole can be located behind the fitting member 20 in the first direction and in front of the fitting member 20 in the second direction. The lower end of the limiting part 50 is connected with the mounting part 40, and the upper end of the limiting part 50 can be lower than the fitting member 20, and the limiting part 50 as a whole can be parallel to the fitting member 20 in the first position 24. For the convenience of description, the first direction is defined as right, the second direction is defined as left, the left side surface of the fitting member 20 is provided with an avoiding groove 23, and the limiting part 50 is located on the left side of the fitting member 20. When the upper end of the fitting member 20 is counterclockwise rotated, the fitting member 20 is limited by the limiting part 50 and cannot continue to rotate counterclockwise. At this time, the limiting part 50 is located in the avoiding groove 23, which can increase the contact area between the limiting part 50 and the fitting member 20, improve the stability of the fitting member 20 in the first position 24, and also improve the compactness of the structure, so as to avoid that the limiting part 50 and the fitting member 20 occupy too much space when they are matched. In addition, by containing the limiting part 50 in the avoiding groove 23, the limiting part 50 can avoid interfering with the matching part 31 on the second movable member 30. For example, the fitting member 20 on the rack is a first matching tooth, the matching part 31 on the gear is a second matching tooth, when the first matching tooth is in the first position 24, there is only the first matching tooth between the adjacent two second matching teeth, which will not cause at least part of the limiting part 50 to extend between the adjacent two second matching teeth and interfere with the movement of the gear.

[0090] According to one embodiment of the present application, as shown in Figure 7 and Figure 8 The transmission assembly 100 further comprises a first reset member 60, which is arranged on the first movable member 10, and at least part of the first reset member 60 is located between the first position 24 and the second position 25. The first reset member 60 is used to drive the fitting member 20 in the second position 25 to move to the first position 24. By arranging the first reset member 60, when the first movable member 10 ends the movement in the second direction, the fitting member 20 can be restored to the first position 24, so as to prepare for the continuous movement of the first movable member 10 in the first direction.

[0091] In some specific embodiments of the present application, as shown in Figure 8 and Figure 10 The first reset member 60 is a spring. In this embodiment, the spring has the advantages of easy recovery after deformation and balanced force on the fitting member 20.

[0092] According to one embodiment of the present application, as shown in Figure 8 and Figure 15As shown, the first reset member 60 is rotatably connected with the first movable member 10. In installation, the fitting member 20 and the elastic sheet can be sequentially placed into the fixing groove between the two mounting holes 45 of the mounting portion 40, and then the rotating shaft 90 is sequentially passed through a portion of the mounting portion 40, a portion of the fitting member 20, the elastic sheet, another portion of the fitting member 20 and another portion of the mounting portion 40, so as to fix the fitting member 20, the mounting portion 40 and the elastic sheet together.

[0093] According to one embodiment of the present application, as Figure 10 shown, the first reset member 60 comprises a first connecting section 61, an intermediate section 62 and a second connecting section 63, the first end of the first connecting section 61 is rotatably connected with the first movable member 10, the first end of the intermediate section 62 is connected with the second end of the first connecting section 61, the intermediate section 62 is spaced apart from the fitting member 20 and the first movable member 10 when the fitting member 20 is located at the first position 24, the intermediate section 62 abuts against the first movable member 10 when the fitting member 20 is located at the second position 25, the first end of the second connecting section 63 is connected with the second end of the intermediate section 62, and the second end of the second connecting section 63 abuts against the fitting member 20.

[0094] That is, the first connecting section 61 is connected with the first end of the fitting member 20, the intermediate section 62 is bent and protrudes towards the bottom surface of the accommodating groove 41, and the second connecting section 63 is in contact with the fitting member 20. When the fitting member 20 is moved from the first position 24 to the second position 25, the elastic force of the elastic sheet needs to be overcome, and when the fitting member 20 is located at the second position 25, the intermediate section 62 is deformed due to the abutment against the bottom surface of the accommodating groove 41, and the elastic sheet exerts a force on the fitting member 20 towards the first position 24. That is, in this embodiment, the elastic sheet is used to control the fitting member 20 located at the second position 25 to have a movement tendency to move towards the first position 24, and without the obstruction of other parts, the fitting member 20 at the second position 25 can be moved to the first position 24 under the action of the elastic sheet to wait for the first movable member 10 to move again in the first direction.

[0095] In addition, at least a portion of the accommodating groove 41 defined between two adjacent mounting portions 40 can serve as a clearance space, so that when the fitting member 20 is forced to rotate, the elastic sheet is compressed and moves towards the clearance space.

[0096] Further, as Figure 16 shown, the mounting portion 40 is provided with a stepped portion 44, for example, the upper end of the mounting portion 40 is provided with a mounting hole 45 for passing through the rotating shaft 90, the stepped portion 44 is located below the mounting hole 45 and above the first movable member 10, and the end of the stepped portion 44 in the horizontal direction can extend towards the accommodating groove 41. After the elastic sheet, the fitting member 20 and the mounting portion 40 are assembled, the elastic sheet is supported by the stepped portion 44 and presses against the fitting member 20, so that the fitting member 20 is located at the first position 24.

[0097] In some embodiments of the present application, as shown in Figure 1 and 4 The transmission assembly 100 further comprises a bracket 70 and a second reset member 80. The bracket 70 is provided with a limiting groove 71, and the first movable member 10 is installed in the limiting groove 71. The second reset member 80 is arranged in the limiting groove 71 and connected with the first movable member 10 and the bracket 70, so as to exert a force on the first movable member 10 in the first direction or the second direction.

[0098] The cooperation between the first movable member 10 and the second reset member 80 is described below.

[0099] For example, the first movable member 10 is located at the left side of the second reset member 80, the first direction is the right movement, and the second direction is the left movement.

[0100] When the second reset member 80 is in a free state, the second reset member 80 does not exert a force on the first movable member 10. When the first movable member 10 moves to the right, the right end of the first movable member 10 presses the second reset member 80, overcomes the elastic potential energy of the second reset member 80, the first movable member 10 exerts a right force on the second reset member 80, and the second reset member 80 is deformed by extrusion. When the right force on the first movable member 10 is stopped, the second reset member 80 gradually recovers from the extrusion state to the free state, exerts a left force on the first movable member 10, and the first movable member 10 moves to the second direction by itself.

[0101] In this embodiment, by limiting the limiting groove 71 on the bracket 70, the installation of the first movable member 10 is facilitated. By installing the second reset member 80 in the limiting groove 71, the restoring force of the second reset member 80 is utilized, and when it is necessary to drive the first movable member 10 to move in the second direction, external auxiliary action is not required or is reduced, labor intensity is reduced, energy is saved, and intelligent and automatic structure is realized.

[0102] According to one embodiment of the present application, as shown in Figure 1 The second reset member 80 is a spring, which has the advantages of wide source and low price. As shown in Figure 5 A spring limiting column 75 coaxial with the stretching and compression direction of the spring can also be arranged in the limiting groove 71. When installing, the cavity of the spring is sleeved on the spring limiting column 75, and then the rack is slid into the limiting groove 71 from the mouth of the limiting groove 71.

[0103] Further, as shown in Figure 1 and Figure 2As shown, the second movable element 30 is also mounted on the bracket 70, for example, above the upper opening of the limiting groove 71, and the second movable element 30 is located above the limiting groove 71. For example, the gear is put into the positioning groove of the bracket 70 and fixed with the cover plate and two screws, at this time, the rack and the gear are connected in cooperation.

[0104] Further, as shown in Figure 3 In order to avoid the deviation of the first movable element 10 when moving along the first direction or the second direction, a guide groove 72 is defined on the side wall of the limiting groove 71, and a guide part is arranged on the side surface of the first movable element 10 and inserted into the guide groove 72. When the first movable element 10 extends in the horizontal direction and is movable in the left-right direction, as shown in Figure 4 The guide groove 72 can include an upper guide groove 73 and a lower guide groove 74, the upper guide groove 73 is located above the lower guide groove 74, the upper guide groove 73 can extend in the up-down direction and extend to the outside of the bracket 70, and the lower guide groove 74 extends in the left-right direction, which is beneficial to the guide part to pass through the upper guide groove 73 first and then slide to the lower guide groove 74, facilitating the installation of the guide part and avoiding the disengagement between the guide part and the bracket 70. Further, by limiting the length of the guide groove 72 in the horizontal direction, the stroke of the first movable element 10 moving in the left-right direction can be limited.

[0105] According to an embodiment of the present application, as shown in Figure 2 , Figure 17 and Figure 18 A rolling bearing 11 is also mounted on the side surface of the first movable element 10, when the first movable element 10 moves along the extending direction of the limiting groove 71, the rolling bearing 11 can rotate around its own axis and contact the bottom surface of the limiting groove 71, thereby reducing the friction between the first movable element 10 and the bottom surface of the limiting groove 71. The rolling bearing 11 can also serve as a guide part, and when installed, the rolling bearing 11 is clamped in the guide groove 72.

[0106] Further, as shown in Figure 3 The number of rolling bearings 11 is four, and the first movable element 10 is a cube, and when installed, the four rolling bearings 11 are sequentially installed on the rotating shaft of the side surface of the rack, specifically, two rolling bearings 11 are arranged on each of the two length directions of the rack. In this embodiment, the use of rolling bearings 11 facilitates smooth movement of the rack.

[0107] The transmission assembly 100 of the embodiment of the present application will be described in detail below in conjunction with the embodiments.

[0108] The first movable member 10 and the engaging member 20 are engaged as a rack extending in the left-right direction, and the second movable member 30 is a gear located above the rack with its axis perpendicular to the extending direction of the rack. An installation portion 40 is provided above the rack, and the engaging member 20 is a first engaging tooth, the lower end of which is hinged to the installation portion 40. Before the rack is pushed to the right, a limiting portion 50 is provided on the left side of the first engaging tooth, a spring piece is provided on the right side, and a second engaging tooth is provided on the upper right side. A spring is provided on the right side of the rack.

[0109] As shown in Figure 11 , when a rightward force is applied to the left end of the rack, the rack will move rightward against the elastic force of the spring. As the rack moves rightward, the first engaging tooth also moves rightward, and the upper end of the first engaging tooth rotates counterclockwise until the upper end of the first engaging tooth comes into contact with the second engaging tooth. At this time, the upper end of the first engaging tooth cannot continue to rotate counterclockwise under the action of the limiting portion 50, and the first engaging tooth stays at the first position 24, with the upper end of the first engaging tooth meshing with the second engaging tooth. If the second engaging tooth of the gear is further pushed to the right, the first engaging tooth can drive the second engaging tooth to rotate synchronously, and the gear rotates counterclockwise about its own axis, as shown in Figure 13 .

[0110] The following is a force analysis of the first engaging tooth and the second engaging tooth when the rack moves rightward.

[0111] The first engaging tooth is at the first position 24, and the second engaging tooth is on the right side of the first engaging tooth. When the rack is pushed to the right, the first engaging tooth is subjected to a rightward force F1, and when the first engaging tooth pushes the second engaging tooth to the right, the first engaging tooth exerts a force F2 on the second engaging tooth, which in turn exerts a leftward force F3 on the first engaging tooth. The limiting portion 50 exerts a force F4 on the first engaging tooth, which balances the force F3, and the first engaging tooth remains at the first position 24. Since F1 is greater than F2 in the left-right direction, the first engaging tooth moves rightward while remaining at the first position 24.

[0112] As shown in Figure 14 , when the rack moves to the bottom right, the rightward pressing force is removed, and the rack will return to the left to the first position 24 under the push of the spring. Before returning, the second engaging tooth is located above and to the left of the first engaging tooth. During the return process, the first engaging tooth moves to the left until it encounters the second engaging tooth, and the first engaging tooth is subjected to a rightward force exerted by the second engaging tooth, as shown in Figures 15 to 18As shown, the first engaging tooth rotates clockwise because the right side of the first engaging tooth is not limited by a limiting structure. The rotation of the second engaging tooth requires a certain pushing force value to rotate, that is, the first engaging tooth will not exert a pushing force of sufficient size on the second engaging tooth due to the avoidance, that is, the first engaging tooth will not rotate the second engaging tooth in the returning process, until the rack returns to the initial state. That is, when the rack moves to the left, the first engaging tooth will flip over instead of synchronously rotating the second engaging tooth when it encounters the second engaging tooth. When the second engaging tooth needs to rotate again, press the rack to the right again, and the process is repeated, that is, the second engaging tooth is subjected to intermittent and same-direction pushing force.

[0113] It can be seen that the one-way rack in embodiment 1 can be used for cyclic one-way control. When the rack pushes the gear, it is forward movement, and when the rack returns to the original route, it does not push the gear, which is reverse movement. The two movements produce different output effects and can be used in corresponding two different scene-defined environments.

[0114] The electronic device according to the embodiment of the present application comprises the transmission assembly 100 according to any one of the above embodiments. When the transmission assembly 100 according to the present application is used in an electronic device, the electronic device can be a PC, a notebook, a smart wearable device, etc., and the smart wearable device can be a smart watch, smart glasses, etc. In application, the storage and taking out of an article, which can be an electronic component, can be achieved by pressing the first movable member 10 in one direction. For example, a user presses the first movable member 10 in the first direction for the first time, pushes a battery into the storage space through the first movable member 10, drives the second movable member 30, and finally locks the battery in the storage space. When the user presses the first movable member 10 in the first direction for the second time, the first movable member 10 can drive the second movable member 30 to continue to move, and finally unlock the battery in the storage space and take it out. Since the transmission assembly 100 according to the embodiment of the present application can provide intermittent driving force by one-way movement and improve the compactness of the structure, the electronic device according to the embodiment of the present application also has the above advantages, which will not be described here. The electronic device can be a smart wearable device or other electronic product.
