Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical transmission, and specifically relates to a transmission mechanism. Background Art

[0002] With the development of the times and the development of people's aesthetic concepts, the requirements for the external structure of various products have become increasingly high. At the same time, the requirements for the transmission components under the external structure of the products have also become higher. It has become an urgent problem to be solved to be able to complete the transmission without occupying more space within a limited space. For example, when household appliances are in use, due to the limited space in the home and the limited external shape of the electrical products themselves, it is urgent to improve the transmission part of the electrical products.

[0003] Chinese Patent with application number CN200820141240.3 discloses a multi-gear telescopic hinge link, including an outer sheath, a telescopic link, a positioning bolt, and a gear tooth. A gear position device is provided at the inner end of the telescopic link, including a fixed gear elastic piece, a reverse gear slider, and an elastic member. One end of the fixed gear elastic piece is a connection end, and the other end is a free end. The elastic member is arranged between the fixed gear elastic piece and the telescopic link. The positioning bolt is fixedly arranged at the free end of the fixed gear elastic piece. A hollow bolt groove is provided in the reverse gear slider, which consists of a horizontal chute and a sloping chute. The reverse gear slider is sleeved on the positioning bolt through the bolt groove.

[0004] Chinese Patent with application number CN201611081707.5 discloses a limiting mechanism, including a chute, a slider, a stop block, an upper locking block, a link, and a spring. One end of the upper locking block is hinged to the link, and the other end is movably connected to the slider. The stop block is installed on the slider, and the slider is installed in the chute and can slide along the chute. One end of the spring is connected to the slider, and the other end is connected to the stop block. The stop block can slide relative to the slider along the telescopic direction of the spring. At the same time, an angle is formed between the upper locking block and the slider. When the spring is in a compressed state, its elastic force causes the slider, the stop block, and the chute to generate a squeezing force to prevent the slider from sliding freely.

[0005] The above-mentioned prior art has proposed technical solutions regarding the transmission mechanism, but the hinge link transmission is relatively complex, and the limiting mechanism cannot well achieve functions such as transmission. Therefore, the above-mentioned prior art still has deficiencies.

[0006] Therefore, it is necessary to improve the deficiencies and defects of the prior art, and provide a transmission mechanism. By setting the running track of the transmission mechanism, the movement power of the first slider is transmitted to the second slider, and a mechanism capable of converting linear motion into rotational motion is provided on the second slider. While meeting the transmission function, the space occupied by the transmission mechanism is reduced, and the space utilization efficiency is improved.

[0007] In view of this, the present invention is specifically proposed. Summary of the Invention

[0012] a first slider and a second slider movably arranged on the connecting rod assembly and capable of sliding corresponding to the first chute and the second chute;

[0013] wherein, the sliding of the first slider in the first chute drives the second slider to slide synchronously in the second chute through the connecting rod assembly.

[0014] In addition, the sliding of the first slider and the second slider in the first chute and the second chute is a linear motion;

[0019] Meanwhile, the connecting rod assembly includes a first connecting rod and a second connecting rod;

[0020] The first connecting rod is matched with a rotating shaft and can rotate around the rotation center;

[0021] When the first connecting rod rotates around the rotation center, the second connecting rod can extend into or out of the first connecting rod along the length direction of the first connecting rod.

[0022] Further, one end of the first connecting rod is matched with the first slider, and a position near the other end is matched with the rotating shaft arranged at the rotation center;

[0023] The first connecting rod is provided with a connecting rod groove that can at least accommodate the second connecting rod to extend into or out of;

[0024] A first opening that is elongated and arranged along the length direction of the first link is further provided in the link groove of the first link.

[0026] When the first link rotates around the rotation center, the first guiding post of the first slider slides in the first opening under the action of the first link.

[0027] Still further, one end of the second link is rotatably fitted with the second slider, and the other end is provided with a second guiding post.

[0028] The second guiding post cooperates with the first opening of the first link.

[0029] When the first link rotates around the rotation center, the second guiding post of the second slider slides in the first opening under the action of the first link.

[0030] Still further, the second link is provided with a second opening that cooperates with the rotating shaft.

[0031] The second opening is a long strip opening arranged along the length direction of the second link.

[0032] And one end of the second slider is fitted with the second link, and an installation portion is provided at a position near the other end.

[0033] The installation portion is a cylindrical structure with a through hole in the center.

[0034] In one embodiment, a rotating portion cooperates with the through hole in the center of the installation portion.

[0059] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0060] Figures 1 to 4These are the first and second schematic views of the side of the transmission mechanism shaft of the present invention and the first and second schematic views of the front view of the transmission mechanism. As can be seen from Figures 1 to 4 this, the main body of the transmission mechanism is a base 1. The connecting rod assembly 2 rotates around the rotation center 3 on the base 1. The base 1 is also provided with a first slider 4 and a second slider 5 that cooperate with both ends of the connecting rod assembly 2. The connecting rod assembly 2 forms a pendulum-like motion around the rotation center 3 on the base 1. Under the action of the connecting rod assembly 2, the movement trajectories generated by the first slider 4 and the second slider 5 are parallel. In one embodiment, the movement trajectories of the first slider 4 and the second slider 5 are linear movements. In practical applications, the movement trajectories of the first slider 4 and the second slider 5 can be set as arcs according to needs. In addition, a first chute 101 and a second chute 102 are also provided on the base 1, corresponding to the first slider 4 and the second slider 5 respectively. The first slider 4 and the second slider 5 form their movement trajectories under the action of the first chute 101 and the second chute 102.

[0061] Furthermore, the connecting rod assembly 2 includes a first connecting rod 201 and a second connecting rod 202. The first connecting rod 201 cooperates with the rotating shaft 301 and rotates around the rotation center 3. In Figure 1 、 3 and 4, the rotating shaft 301 and the rotation center 3 are marked at the same position. In practical applications, a rotating shaft 301 will be installed at the rotation center 3 to position the first connecting rod 201. Here, for the convenience of observation, the two are marked as one body. On the side of the first connecting rod 201 facing the base 1, a connecting rod groove 203 is provided in the length direction of the first connecting rod 201. When the connecting rod assembly 2 rotates, the second connecting rod 202 can extend into or out of the range of the connecting rod groove 203 in the length direction of the first connecting rod 201. The first connecting rod 201 is also provided with a first opening 204 in its length direction. A first guiding column 401 that cooperates with the first opening 204 is provided on the first slider 4. When the connecting rod assembly 2 rotates, the first guiding column 401 drives the first slider 4 to slide along the first chute 101 under the action of the first opening 204. At the same time, the second connecting rod 202 is provided with a second guiding column 205 that cooperates with the first opening 204.

The second connecting rod 202 is also provided with a second opening 206 that cooperates with the rotating shaft 301. When the second connecting rod 202 extends into or out of the length direction of the first connecting rod 201, the second opening 206 of the second connecting rod 202 also plays a guiding role and at the same time prevents the second connecting rod 202 from deviating from the connecting rod groove 203.

[0062] Further, a first limiting portion 103 and a second limiting portion 104 are provided on the base 1, and the first slider 4 is respectively engaged with the first limiting portion 103 and the second limiting portion 104 to realize the rotational movement of the link assembly 2 within a certain range.

[0063] Still further, one end of the second slider 5 is rotatably engaged with the second link 202, and the other end is provided with a mounting portion 501. The mounting portion 501 is a hollow cylindrical structure, and a rotating portion 6 is also provided in cooperation with the mounting portion 501. A first baffle 502 is provided on the mounting portion 501, and a second baffle 601 is provided on the rotating portion 6. A torsion spring 7 is provided outside the mounting portion 501 and is engaged with the first baffle 502 and the second baffle 601. Figure 10 As can be seen, a guiding portion 105 is provided. The torsion spring 7 is engaged with the guiding portion 105 provided inside the base. The torsion spring 7 and the guiding portion 105 realize the switching between linear motion and rotational motion. The guiding portion 105 is an arc-shaped guiding structure. After the linear motion is converted into rotational motion, the torsion spring 7 provides a restoring force. With this setting, the rotational motion of the link assembly 2 is converted into the linear motion of the second slider 5, and then the linear motion of the second slider 5 is converted into the rotational motion of the rotating portion 6, providing various application scenarios of the transmission mechanism.

[0064] Figure 5 is a schematic diagram of the first link 201 of the transmission mechanism of the present invention. In Figure 5 As can be seen, a link groove 203 is provided in the length direction of the first link 201. The link groove 203 cooperates with the second link 202 to form a channel for the second link 202 to slide within the first link 201. A first opening 204 is also provided on the first link 201. The first opening 204 cooperates with the first guiding column 401 and the second guiding column 205. In addition, a rotation center 3 and a rotation shaft 301 are provided on the first link 201. During actual installation, the rotation center 3 needs to pass through a rotation shaft 301, and the first link 201 rotates around the rotation shaft 301. For the convenience of observation, in Figure 5 the rotation shaft 301 is omitted, and the rotation center 3 and the rotation shaft 301 are marked together.

[0065] Figure 6 is a schematic diagram of the second link 202 of the transmission mechanism of the present invention. In Figure 6 As can be seen, a second opening 206 and a second guiding column 205 are provided on the second link 202. The second opening 206 cooperates with the rotation shaft 301 to form a guide for the second link 202 to extend into and out of the first link 201. The second guiding column 205 cooperates with the first opening 204 of the first link 201. The other end of the second link 202 is engaged with the second slider 5. As can be seen from Figure 6 the cooperation between the second link 202 and the second slider 5 is a rotational cooperation.

[0066] Figure 7 and Figure 8 are schematic diagrams of the first slider 4 and the second slider 5 of the transmission mechanism of the present invention. As can be seen from Figure 7 and Figure 8 , the first slider 4 is provided with a first guide post 401, and the second slider 5 is provided with a rear mounting portion 501 and a first baffle 502.

[0067] Figure 9 and Figure 10 are schematic diagrams of the rotating part 6 and the guiding part 105 of the transmission mechanism of the present invention. As can be seen from Figure 9 , the rotating part 6 is provided with a second baffle 601, which cooperates with the first baffle 502 of the second slider 5 to cooperate with the torsion spring 7. The torsion spring 7 cooperates with the guiding part 105 provided inside the base 1. The torsion spring 7 and the guiding part 105 realize the switching between linear motion and rotational motion. The guiding part 105 has an arc-shaped guiding structure. After the linear motion is transformed into rotational motion, the torsion spring 7 provides a restoring force to realize the conversion of the linear motion of the second slider 5 into the rotational motion of the rotating part 6.

[0068] Generally speaking, in the present invention, the base 1 cooperates with the link assembly 2, and the movement trajectories of the two sliders connected to the link assembly 2 are defined, ensuring that under the action of the link assembly 2, the movement power of the first slider 4 is transmitted to the second slider 5, and the movement trajectories of the two sliders are parallel. At the same time, the transmission mechanism has the characteristics of small occupied space and small movement amplitude; by setting the link assembly 2 to a structure that can expand and contract during rotation, the direction and amplitude of the movement trajectory of the slider during movement are controlled, ensuring that while the transmission mechanism transmits motion, the space problem caused by its too large size is avoided; a rotating part 6 and a torsion spring 7 are provided at one end of the second slider 5. The torsion spring 7 cooperates with the guiding part 105 provided inside the base to convert the linear motion of the slider into rotational motion, improving the adaptation range of the device and expanding the space for the application of the device in products.

In addition, a first chute 101 and a second chute 102 are further provided on the base 1, corresponding to the first slider 4 and the second slider 5 respectively. The first slider 4 and the second slider 5 form their movement trajectories under the action of the first chute 101 and the second chute 102.

[0086] Further, the link assembly 2 includes a first link 201 and a second link 202, wherein the first link 201 is engaged with the rotary shaft 301 and rotates around the rotation center 3. In Figure 1 、 3In FIGS. 3 and 4, the rotation axis 301 and the rotation center 3 are marked at the same position. In actual applications, a rotation axis 301 is installed at the rotation center 3 for positioning the first link 201. Here, for the convenience of observation, the two are marked as one entity. The first link 201 faces the base 1. A link groove 203 is provided in the length direction of the first link 201.

The first opening 204 cooperates with the first guide post 401 and the second guide post 205. In addition, the first link 201 is also provided with a rotation center 3 and a rotation axis 301. During actual installation, the rotation center 3 needs to pass through a rotation axis 301, and the first link 201 rotates around the rotation axis 301. For the convenience of observation, in Figure 5 the rotation axis 301 is omitted, and the rotation center 3 and the rotation axis 301 are marked together.

[0088] Figure 6 is a schematic diagram of the second link 202 of the transmission mechanism of the present invention. In Figure 6 it can be seen that the second link 202 is provided with a second opening 206 and a second guide post 205. The second opening 206 cooperates with the rotation axis 301 to form a guide for the second link 202 to extend into and out of the first link 201. The second guide post 205 cooperates with the first opening 204 of the first link 201. The other end of the second link 202 cooperates with the second slider 5. From Figure 6It can be seen that the cooperation between the second connecting rod 202 and the second slider 5 is a rotational cooperation.
