[0002] With rapid economic development, people's demands for a better life are increasing. To meet the growing needs of consumers, various types of gear shifting mechanisms have emerged. In application number 202311299221.9, I proposed a downward-pressing gear shifting controller. By pressing down the gear shift lever and pushing it forward and backward, four gears can be adjusted. The operation is simple, and no left or right adjustment of the gear shift lever is required during gear shifting, effectively reducing the operating space of the gear shift lever during the shifting process. This creates a favorable environment for gear shifting and effectively reduces the safety hazards caused by the large operating space required during gear shifting.

[0003] However, during use, customer feedback indicates that due to the presence of the long slot, dust can easily accumulate and fall into the shift controller, affecting its shifting operation. Additionally, debris may fall into the long slot, affecting the normal operation of the shift controller and posing a certain degree of safety risk. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-type dustproof shift controller that can prevent dust accumulation in the long slot without affecting the forward, backward, up, and down movement of the shift lever, thus avoiding dust accumulation or debris falling into the shift controller and affecting its shifting operation, thereby reducing safety risks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pressure-type dustproof shift controller, including a bracket and a shift lever mounted on the bracket. A central shaft is rotatably mounted through the inside of the bracket. A first rocker arm and a second rocker arm are respectively sleeved and rotatably mounted on both sides of the outer periphery of the central shaft. The top of the first rocker arm and the second rocker arm are both provided with cross grooves. The cross groove on the second rocker arm is located below the cross groove on the first rocker arm, and the two cross grooves are aligned at their centers. A long groove is provided on the top of the bracket. The bottom end of the shift lever passes through the long groove and the two cross grooves in sequence, passes through the central shaft, and is threaded with a nut. A spring is sleeved on the outer periphery of the shift lever. A fixing pin is welded through and fixed to the surface of the shift lever, and the fixing pin is used in conjunction with the cross groove. The two ends of the spring are in contact with the surface of the fixing pin and the surface of the central shaft, respectively.

[0006] The long groove is equipped with flexible dustproof nets in front of and behind the shift lever. The flexible dustproof net has an arc-shaped silicone strip that contacts and fits the shift lever on the side near the shift lever. A spring is provided at the bottom of the flexible dustproof net. One end of the spring is fixedly connected to the corresponding arc-shaped silicone strip, and the other end is fixedly connected to the bracket.

[0007] Preferably, the bracket has guide grooves on both sides of the flexible dustproof net to guide it.

[0008] Preferably, the first rocker arm includes a first arc plate and a first support plate, wherein the first arc plate is welded and fixed to the top of the first support plate.

[0026] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.

[0027] This utility model discloses a downward-pressing dustproof shift controller. For example... Figure 1-4 As shown, the embodiment includes a bracket 1 and a shift lever 5 mounted on the bracket 1. A central shaft 2 is rotatably mounted through the interior of the bracket 1. A first rocker arm 3 and a second rocker arm 4 are respectively sleeved and rotatably mounted on both sides of the outer periphery of the central shaft 2. A cross groove 9 is provided on the top of both the first rocker arm 3 and the second rocker arm 4. The cross groove 9 on the second rocker arm 4 is located below the cross groove 9 on the first rocker arm 3, and the two cross grooves 9 are aligned at their centers.

[0028] As described in detail, the first rocker arm 3 includes a first arc plate and a first support plate, with the first arc plate welded and fixed to the top of the first support plate. The first support plate is sleeved and rotatably mounted on the outer periphery of the central shaft 2, and the cross groove 9 is formed on the top of the first arc plate.

[0029] As described in detail, the second rocker arm 4 includes a second arc plate and a second support plate, with the second arc plate welded and fixed to the top of the second support plate. The second arc plate is positioned below the first arc plate. The second support plate is sleeved and rotatably mounted on the outer periphery of the central shaft 2, and the cross groove 9 is formed on the top of the second arc plate.

[0030] As a preferred embodiment, in order to facilitate the effective cooperation between the shift lever 5 and the bracket 1, the first rocker arm 3 and the second rocker arm 4, the top of the bracket 1 is provided with a long groove, the bottom end of the shift lever 5 passes through the through long groove and two cross grooves 9 in sequence, passes through the central shaft 2 and is threaded with a nut 8, and a fixing pin 11 is welded and fixed through the surface of the shift lever 5, and the fixing pin 11 is used in conjunction with the cross grooves 9.

[0031] As a preferred embodiment, in order to achieve automatic reset of the shift lever 5 structure, a spring 7 is sleeved on the outer periphery of the shift lever 5, and the two ends of the spring 7 are in contact with the surface of the fixing pin 11 and the surface of the central shaft 2, respectively.

[0032] As a preferred embodiment, to ensure the stability of the first and second support plate structures, both sides of the bracket 1 are threaded with a set screw 6. One end of one set screw 6 is used to engage with one side of the first support plate, and the other end of the set screw 6 is used to engage with one side of the second support plate. The surface of the central shaft 2 is provided with a first limiting groove and a second limiting groove. A first retaining spring adapted to the other side of the first support plate is engaged inside the first limiting groove, and a second retaining spring adapted to the other side of the second support plate is engaged inside the second limiting groove.

[0033] As an extension, the first support plate 302 and the second support plate 402 each have two circular grooves on the side near the bracket 1. The front end of the set screw 6 is a small ball embedded in the circular groove, so that when the gear returns to the center position, it gives the operator a damping feeling and thus ensures safe driving.

[0034] When in use, when the spring 7 is not under pressure, the fixing pin 11 is in the cross groove 9 on the first arc plate;

[0035] First gear adjustment: Push the shift lever 5 forward. The shift lever 5 moves forward along the long groove. During the process, the fixing pin 11 drives the first arc plate to move. The first arc plate drives the first support plate to rotate forward around the central axis 2, thereby controlling the first gear.

[0036] Second gear adjustment: Push the shift lever 5 forward. The shift lever 5 moves backward along the long groove. During the process, the fixing pin 11 drives the first arc plate to move. The first arc plate drives the first support plate to rotate backward around the central axis 2, thereby controlling the second gear.

[0037] Third gear adjustment: Press down the shift lever 5, the shift lever 5 drives the fixing pin 11 to move downward, the spring 7 is compressed, so that the fixing pin 11 is inserted into the cross groove 9 of the second arc plate, and then push the shift lever 5 forward, the shift lever 5 drives the fixing pin 11 to push the second arc plate to move, the second arc plate drives the second support plate to rotate forward around the central axis 2, thereby controlling the third gear;

[0038] Fourth gear adjustment: Press down the shift lever 5, the shift lever 5 drives the fixing pin 11 to move downward, the spring 7 is compressed, so that the fixing pin 11 is inserted into the cross groove 9 of the second arc plate, and then push the shift lever 5 backward, the shift lever 5 drives the fixing pin 11 to push the second arc plate to move, the second arc plate drives the second support plate to rotate backward around the central axis 2, thereby controlling the fourth gear;

[0039] When operation stops, the shift lever 5 returns to the neutral position, the groove on the side of the second rocker arm 4 engages with the set screw 6, causing the fixing pin 11 to spring up under the reaction force of the spring 7, pushing the fixing pin 11 into the cross groove 9 on the first arc plate, thus conveniently triggering the return to neutral.

[0040] Based on the original design, flexible dustproof nets 10 are respectively installed before and after the shift lever 5 in the long groove. The flexible dustproof net 10 has an arc-shaped silicone strip that contacts and fits against the shift lever 5 on the side closest to it. A spring is installed at the bottom of the flexible dustproof net 10, with one end fixedly connected to the corresponding arc-shaped silicone strip and the other end fixedly connected to the bracket 1. The bracket 1 has guide grooves on both sides of the flexible dustproof net 10 to guide it. The spring has a low elastic coefficient, resulting in minimal resistance to the movement of the shift lever 5, and ensuring that the flexible dustproof net 10 can be shaped and its size changed.

[0041] When the shift lever 5 is in the neutral position, both springs are compressed. Due to the spring's rebound force, the two arc-shaped silicone strips are tightly attached to both sides of the shift lever 5, and the two sets of flexible dustproof nets 10 are used to cover the long slot. When the shift lever 5 moves forward or backward, one spring rebounds and the other spring is further compressed, so that the two arc-shaped silicone strips are still tightly attached to both sides of the shift lever 5, and the two sets of flexible dustproof nets 10 still completely cover the long slot. When the size and shape of the flexible dustproof nets 10 change, the guide groove guides them.

[0042] It should be noted that the parts not described in detail in the above embodiments are all prior art.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model should be covered within the protection scope of the present utility model.
