Description

Technical Field

[0001] This invention relates to the field of three-wheeled motorcycle technology, and particularly to a parking lock system and a three-wheeled motorcycle. Background Technology

[0002] When parking or stationary, vehicles such as three-wheeled motorcycles and all-terrain vehicles (ATVs) typically rely on parking lock systems to prevent accidental movement or tipping. In existing technology, the parking lock mechanism for these vehicles usually employs a separate design: the locking mechanism restricting forward and backward movement is separate from the support or locking structure preventing left and right tipping. This separate design results in a large number of locking-related components scattered throughout the vehicle structure, increasing assembly steps and manufacturing costs, and also causing inconvenience for users. Users must perform two or more steps to operate the movement lock and anti-tipping device separately, a cumbersome process that can easily lead to omissions or delays in operation during emergency or quick parking situations, affecting safety and user experience.

[0003] Therefore, there is an urgent need for a parking system that can reliably lock the vehicle's forward and backward movement and left and right tilting simultaneously through single or integrated operation, thereby simplifying the structure, facilitating assembly and use, and improving operational convenience and overall safety. Summary of the Invention

[0004] The purpose of this invention is to provide a parking locking system and a three-wheeled motorcycle that can reliably lock the vehicle's forward and backward movement and left and right tilting through a single operation, simplifying the structure, facilitating assembly and use, and improving operational convenience and overall safety.

[0005] To achieve the above objectives, the present invention provides a parking locking system, comprising:

[0006] The dispenser housing has an internal receiving cavity;

[0007] The movable component, located within the receiving cavity, is movable relative to the dispenser housing;

[0008] The first cable is connected to the driving part of the moving component, and the first cable can drive the moving component to move;

[0009] The second cable is connected to the driven part of the moving part, and the end of the second cable away from the driven part is connected to the left brake assembly;

[0010] The third cable is connected to the driven part of the moving part, and the end of the third cable away from the driven part is connected to the right brake assembly;

[0011] The fourth cable is connected to the driven part of the moving part, and the end of the fourth cable away from the driven part is connected to the yaw assembly.

[0012] In one possible implementation, the dispenser housing includes:

[0013] The distributor seat has a connecting part for connecting to the frame of the three-wheeled motorcycle. The distributor seat has a receiving cavity inside, and one end of the distributor seat has a first opening communicating with the receiving cavity.

[0014] A dispenser cover is connected to one end of the dispenser seat that has a first opening. The dispenser cover is used to close the first opening to restrict the movement of the moving part out of the receiving cavity.

[0015] In one possible implementation, the active part and the driven part are spaced apart in a first direction. The dispenser seat has a second opening and a third opening, which are located at opposite ends of the dispenser seat in the first direction. The active part is located between the second opening and the driven part, and the driven part is located between the third opening and the active part. The first cable passes through the second opening and is connected to the active part. The second cable, the third cable and the fourth cable pass through the third opening and are connected to the driven part.

[0016] In one possible implementation, the movable member is provided with a first sliding surface located on both sides of the movable member in a second direction, and the receiving cavity is provided with a second sliding surface located on the inner side of the cavity wall in the second direction. The second sliding surface is used to contact the first sliding surface so that the movable member slides in the receiving cavity along the first direction, and the second direction is perpendicular to the first direction.

[0017] In one possible implementation, the second opening is used to fix the first protective sleeve sleeved on the first cable, and the third opening is provided with a first protrusion and a second protrusion spaced apart in a second direction to divide the third opening into a first fixing hole, a second fixing hole and a third fixing hole spaced apart in a second direction. The first fixing hole is used to fix the second protective sleeve sleeved on the second cable, the second fixing hole is used to fix the fourth protective sleeve sleeved on the fourth cable, and the third fixing hole is used to fix the third protective sleeve sleeved on the third cable.

[0018] In one possible implementation, the active part is provided with a first mounting groove spaced apart from the second opening in a first direction, and the driven part is provided with a second mounting groove spaced apart from the first fixing hole in a first direction, a third mounting groove spaced apart from the second fixing hole in a first direction, and a fourth mounting groove spaced apart from the third fixing hole in a first direction.

[0019] In one possible implementation, the connecting part is provided with a first connecting hole, and the frame is provided with a second connecting hole. The first connecting hole and the second connecting hole correspond one-to-one. The first connecting member passes through the first connecting hole and is connected to the corresponding second connecting hole, so that the distributor seat is fixedly connected to the frame.

[0020] In one possible implementation, the dispenser base has a third connecting hole at one end facing the dispenser cover, and the dispenser cover has a fourth connecting hole. The third connecting hole and the fourth connecting hole correspond one-to-one. The second connector passes through the fourth connecting hole and connects to the corresponding third connecting hole, so that the dispenser cover and the dispenser base are fixedly connected.

[0021] In one possible implementation, the dispenser cover has a visualization window for observing the position of the moving part.

[0022] Based on the above, this application also provides a three-wheeled motorcycle, including a frame and a parking lock system of any of the above embodiments, with the distributor housing fixed to the frame.

[0023] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: the moving part is installed in the receiving cavity of the distributor housing, the first cable is connected to the active part of the moving part, the second cable with one end connected to the left brake assembly is connected to the driven part of the moving part, the third cable with one end connected to the right brake assembly is connected to the driven part of the moving part, and the fourth cable with one end connected to the sway bar assembly is connected to the driven part of the moving part. When parking is required, the first cable drives the moving part to move relative to the distributor housing, thereby simultaneously driving the second, third, and fourth cables to move synchronously. This allows for simultaneous control of the vehicle's forward and backward movement and left and right tilting. Through a single operation, reliable locking of the vehicle's forward and backward movement and left and right tilting can be achieved simultaneously. This simplifies the structure, facilitates assembly and use, and improves operational convenience and overall safety. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] In the description of this invention, it should be understood that the terms "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this invention.

[0044] The purpose of this invention is to provide a parking locking system and a three-wheeled motorcycle that can reliably lock the vehicle's forward and backward movement and left and right tilting through a single operation, simplifying the structure, facilitating assembly and use, and improving operational convenience and overall safety.

[0045] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0046] Please see Figure 1 and Figure 2 To achieve the above objectives, the present invention provides a parking locking system, including a distributor housing 100, a movable member 200, a first cable 300, a second cable 400, a third cable 500, and a fourth cable 600. The distributor housing 100 has a receiving cavity 110 inside. The movable member 200 is located within the receiving cavity 110 and is movable relative to the distributor housing 100. The first cable 300 is connected to the driving portion 210 of the movable member 200 and can drive the movable member 200 to move. The second cable 400 is connected to the driven portion 220 of the movable member 200, and one end of the second cable 400 away from the driven portion 220 is connected to the left brake assembly 10. The third cable 500 is connected to the driven portion 220 of the movable member 200, and one end of the third cable 500 away from the driven portion 220 is connected to the right brake assembly 20. The fourth cable 600 is connected to the driven part 220 of the moving part 200, and the end of the fourth cable 600 away from the driven part 220 is connected to the yaw assembly 30.

[0047] It should be noted that a locking handle 1200 is located near the handlebars of the tricycle. One end of the first cable 300, away from the moving part 200, is connected to the locking handle 1200. When the tricycle is in normal operation, the locking handle 1200 is in the first position (e.g., Figure 1 (The locking handle 1200 is located on the left side). When the tricycle speed is 0 and parking is required, the locking handle 1200 is moved from the first position to the second position (e.g., the locking handle 1200 is in the middle position). Figure 1The locking handle 1200 is positioned on the right side and held in this position. During this movement, the locking handle 1200 moves the first cable 300, which in turn moves the moving part 200, and pulls the second cable 400, third cable 500, and fourth cable 600 to reliably lock the vehicle's forward and backward movement and left and right tilting. When the three-wheeled motorcycle is released from parking, the locking handle 1200 is moved from the second position to the first position. The second cable 400 and fourth cable 600 are reset by their respective return springs, and the third cable 500 is reset by its return torsion spring, which in turn moves the moving part 200 back to its initial position. The functions of pulling the second cable 400 to move the left brake assembly 10 to restrict the movement of the left rear wheel, pulling the fourth cable 600 to move the right brake assembly 20 to restrict the movement of the right rear wheel, and pulling the cables to restrict the swing of the sway bar are all existing technologies and will not be described further here.

[0048] The movable component 200 is installed within the receiving cavity 110 of the distributor housing 100. A first cable 300 is connected to the driving part 210 of the movable component 200. A second cable 400, one end of which is connected to the left brake assembly 10, is connected to the driven part 220 of the movable component 200. A third cable 500, one end of which is connected to the right brake assembly 20, is connected to the driven part 220 of the movable component 200. A fourth cable 600, one end of which is connected to the yaw assembly 30, is connected to the driving part 210 of the movable component 200. The driven part 220 enables the moving part 200 to move relative to the distributor housing 100 via the first cable 300 when parking is required, thereby simultaneously driving the second cable 400, the third cable 500 and the fourth cable 600 to move synchronously. This allows for simultaneous control of the vehicle's forward and backward movement and left and right tilting. Through a single operation, the forward and backward movement and left and right tilting of the vehicle can be reliably locked simultaneously, simplifying the structure, facilitating assembly and use, and improving operational convenience and overall safety.

[0049] In one possible implementation, the distributor housing 100 includes a distributor seat 120 and a distributor cover 130. The distributor seat 120 is provided with two connecting portions 121, which are spaced apart in a second direction. The connecting portions 121 are used to connect to the frame of a three-wheeled motorcycle. Specifically, the connecting portion 121 is provided with a first connecting hole 1211, and the frame is provided with a second connecting hole. The first connecting hole 1211 and the second connecting hole correspond one-to-one. A first connecting member passes through the first connecting hole 1211 and connects to the corresponding second connecting hole, so that the distributor seat 120 is fixedly connected to the frame. The first connecting hole 1211 and the second connecting hole can be, but are not limited to, threaded holes, and the first connecting member can be, but is not limited to, a screw, to facilitate the installation and removal of the distributor seat 120 from the frame. The dispenser seat 120 is provided with the aforementioned receiving cavity 110 for accommodating the movable member 200 and providing space for the movement of the movable member 200. One end of the dispenser seat 120 is provided with a first opening communicating with the receiving cavity 110 for the movable member 200 to be inserted into the receiving cavity 110.

[0050] The dispenser cover 130 is connected to the end of the dispenser base 120 that has a first opening. Specifically, the end of the dispenser base 120 facing the dispenser cover 130 has a third connecting hole 128, and the dispenser cover 130 has a fourth connecting hole 131. The third connecting hole 128 and the fourth connecting hole 131 correspond one-to-one. The second connecting member 1100 passes through the fourth connecting hole 131 and connects to the corresponding third connecting hole 128, so that the dispenser cover 130 and the dispenser base 120 are fixedly connected. The third connecting hole 128 and the fourth connecting hole 131 can be, but are not limited to, threaded holes, and the second connector 1100 can be, but is not limited to, a screw, to facilitate the installation and removal of the dispenser seat 120 and the dispenser cover 130. Preferably, there are three third connecting holes 128 and three fourth connecting holes 131. One third connecting hole 128 is located on one side of the second opening 122 in the second direction, and the other two third connecting holes 128 are located on both sides of the third opening in the second direction. This satisfies the need for a stable connection between the dispenser seat 120 and the dispenser cover 130, while also reducing space occupation through an integrated design. The dispenser cover 130 is used to close the first opening to restrict the movement of the movable component 200 out of the receiving cavity 110. Furthermore, the dispenser cover 130 is provided with a viewing window 132, such as at least a portion of the dispenser cover 130 being a transparent plate, to facilitate visual observation of the position of the movable component 200 and timely inspection or replacement of the movable component 200.

[0051] In one possible implementation, the active part 210 and the driven part 220 are spaced apart in the first direction. The distributor seat 120 is provided with a second opening 122 and a third opening, which are located at opposite ends of the distributor seat 120 in the first direction. The active part 210 is located between the second opening 122 and the driven part 220, and the driven part 220 is located between the third opening and the active part 210. The first cable 300 passes through the second opening 122 and is connected to the active part 210. The second cable 400, the third cable 500, and the fourth cable 600 pass through the third opening and are connected to the driven part 220. This arrangement ensures that the first cable 300 is located on one side of the moving member 200 in the first direction, and the second cable 400, the third cable 500, and the fourth cable 600 are located on the other side of the moving member 200 in the first direction, thus preventing the first cable 300 from getting tangled with the other cables.

[0052] In one possible implementation, the movable member 200 is provided with a first sliding surface located on both sides of the movable member 200 in the second direction, and the receiving cavity 110 is provided with a second sliding surface 111 located on the inner side of the cavity wall in the second direction. The second sliding surface 111 is used to contact the first sliding surface so that the movable member 200 slides in the receiving cavity 110 along the first direction. When the locking handle 1200 moves from the first position to the second position, the distance the first cable 300 moves is equal to the distance the moving member 200 slides in the first direction. The distance the first cable 300 moves with the locking handle 1200 can be adjusted by adjusting the distance between the first and second positions, thereby adjusting the distance the moving member 200 slides in the first direction. This changes the distance the second cable 400, third cable 500, and fourth cable 600 move when the locking handle 1200 moves from the first position to the second position, ensuring that the distance they move is sufficient to reliably lock the vehicle from forward / reverse movement and from left / right tilting. Alternatively, the lengths of the second cable 400, third cable 500, and fourth cable 600 can be directly adjusted to achieve the parking purpose. In addition, the dispenser seat 120 is also provided with a groove 129. The groove 129 is located at the end of the receiving cavity 110 away from the dispenser cover 130. The groove 129 can reduce the contact area between the side of the moving member 200 away from the dispenser cover 130 and the dispenser seat 120, thereby reducing the friction between the moving member 200 and the dispenser seat 120 when it moves in the first direction. Correspondingly, grease can be provided in the receiving cavity 110 to facilitate the sliding of the moving member 200.

[0053] In one possible implementation, the second opening 122 is used to fix the first protective sleeve 700 sleeved on the first cable 300. The third opening has a first protrusion 123 and a second protrusion 124 spaced apart in a second direction, dividing the third opening into a first fixing hole 125, a second fixing hole 126, and a third fixing hole 127 spaced apart in a second direction. The first fixing hole 125 is used to fix the second protective sleeve 800 sleeved on the second cable 400, the second fixing hole 126 is used to fix the fourth protective sleeve 1000 sleeved on the fourth cable 600, and the third fixing hole 127 is used to fix the third protective sleeve 900 sleeved on the third cable 500. The spaced-apart first fixing hole 125, second fixing hole 126, and third fixing hole 127 allow the second protective sleeve 800, the fourth protective sleeve 1000, and the third protective sleeve 900 to be spaced apart, thereby ensuring that the second cable 400, the fourth cable 600, and the third cable 500 are neatly arranged at the third opening, preventing tangling.

[0054] In one possible implementation, the active part 210 is provided with a first mounting groove 211 spaced apart from the second opening 122 in a first direction, and the driven part 220 is provided with a second mounting groove 221 spaced apart from the first fixing hole 125 in a first direction, a third mounting groove 222 spaced apart from the second fixing hole 126 in a first direction, and a fourth mounting groove 223 spaced apart from the third fixing hole 127 in a first direction. The second opening 122 and the first mounting groove 211 are spaced apart in a first direction such that the extension direction of the first cable 300 between the second opening 122 and the first mounting groove 211 is parallel to the first direction, which is used to prevent the first cable 300 from bending and thus preventing the moving part 200 from moving when parked, while improving the response speed of the moving part 200. The second mounting groove 221 and the first fixing hole 125 are spaced apart in a first direction such that the extension direction of the second cable 400 between the second mounting groove 221 and the first fixing hole 125 is parallel to the first direction, which is used to prevent the second cable 400 from bending and thus preventing the moving part 200 from moving in the reverse direction when the parking is canceled, while improving the response speed of the moving part 200. The third mounting slot 222 and the second fixing hole 126 are spaced apart in the first direction, such that the extension direction of the fourth cable 600 between the third mounting slot 222 and the second fixing hole 126 is parallel to the first direction. This is to prevent the fourth cable 600 from bending, which would prevent the moving part 200 from moving in the reverse direction when the parking brake is released, and at the same time improve the response speed of the moving part 200. The fourth mounting slot 223 and the third fixing hole 127 are spaced apart in the first direction, such that the extension direction of the third cable 500 between the fourth mounting slot 223 and the third fixing hole 127 is parallel to the first direction. This is to prevent the third cable 500 from bending, which would prevent the moving part 200 from moving in the reverse direction when the parking brake is released, and at the same time improve the response speed of the moving part 200.

[0055] Based on the foregoing, this application also provides a three-wheeled motorcycle, including a frame and a parking lock system according to any of the above embodiments, with the distributor housing 100 fixed to the frame. The three-wheeled motorcycle also possesses all the beneficial effects of the parking lock system; the remaining structure of the three-wheeled motorcycle can be referred to in the prior art, and will not be described in detail here.

[0056] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
