DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0025] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0026] The quick shift mechanism structure provided by the embodiment of the utility model is as follows Figures 1 to 4As shown, it includes a pull rod 1 and a sleeve 2; the sleeve 2 has a hollow insertion cavity 21, a stop sleeve 3 is fixed at the upper end of the sleeve 2, and a mounting seat 23 is fixed on the outside of the sleeve 2. The mounting seat 23 can be integrally formed with the sleeve 2, or the mounting seat 23 and the sleeve 2 can be fixedly connected by assembly, and a circuit board 24 is fixed on the mounting seat 23, and a Hall element 25 is provided on the circuit board 24; the pull rod 1 passes through the stop sleeve 3, and the lower end of the pull rod 1 is inserted into the insertion cavity 21 and fixed with a magnet 11; the pull rod 1 is provided with a spring reset component, and the spring reset component provides a spring reset component along the upper and lower sides. The elastic force in the direction of the pull rod 1 is generated, and the spring return assembly resets the pull rod 1 after the external force on the pull rod 1 is removed; when the pull rod 1 is installed and used, the elastic return assembly is compressed when it is subjected to tension or pressure, and at the same time, the positions of the magnet 11 and the Hall element 25 change relative to each other, and then the circuit board 24 outputs a corresponding signal to the vehicle control system, so that the response speed of the shifting system is greatly improved, and feedback can be generated immediately when the driver operates the shift lever, thereby improving the rapidity of the shifting action and high reaction sensitivity. When the tension or pressure on the pull rod 1 is removed, the pull rod 1 moves and resets under the action of the reset elastic force of the spring return assembly.

[0027] The Hall element 25 is preferably configured as a programmable Hall element, so that parameters can be flexibly set according to the user's actual vehicle needs, thereby improving flexibility and adaptability.

[0028] like Figure 3 As shown, the spring return assembly is in the insertion cavity 21, and the sleeve 2 can protect the spring return assembly and make the shift mechanism structure compact. The pull rod 1 is provided with an upper limit portion 12 and a lower limit portion 13 at intervals, and the spring return assembly is sleeved on the pull rod 1 and limited between the upper limit portion 12 and the lower limit portion 13; the upper end of the spring return assembly abuts against the lower end of the stop sleeve 3, and the lower end of the spring return assembly abuts against the limit stop 22 on the sleeve 2, so that it can play an axial limiting role on the pull rod 1 and prevent the pull rod 1 from moving up and down at will. When the pull rod 1 is subjected to an upward pulling force, the spring return assembly is compressed under the cooperation of the lower limit portion 13 and the stop sleeve 3. When the pull rod 1 is subjected to downward pressure, the spring return assembly is compressed under the cooperation of the upper limit portion 12 and the limit stop 22.

[0029] Furthermore, the spring return assembly includes an elastic member 5 (such as a spiral compression spring) and a lower spring seat 6 which are sleeved on the upper spring seat 4. The elastic member 5 is located between the upper spring seat 4 and the lower spring seat 6. Under the elastic force of the elastic member 5, the upper spring seat 4 and the lower spring seat 6 are respectively against the upper limit portion 12 and the lower limit portion 13. The spring return assembly is arranged in this way, with a simple structure and good feasibility.

[0030] like Figure 3As shown, the upper spring seat 4 is provided with a support portion 7 extending downward, and the support portion 7 is used to limit the movable distance between the upper spring seat 4 and the lower spring seat 6, thereby controlling the up and down movable range of the pull rod 1, and preventing the pull rod 1 from moving up and down too much and affecting the performance. When the pull rod 1 moves to the lowermost position, the lower end of the support portion 7 is against the lower spring seat 6; as a modified implementation scheme, an upward extending support portion 7 can also be provided on the lower spring seat 6, and when the pull rod 1 moves to the lowermost position, the upper end of the support portion 7 is against the upper spring seat 4.

[0031] In some embodiments, the support portion 7 is a tubular structure, and the elastic member 5 is located on the inner side of the support portion 7; the upper limit portion 12 and the lower limit portion 13 can be set as a retaining spring, a retaining ring or a step formed on the pull rod 1, so that the upper limit portion 12 and the lower limit portion 13 respectively form an effective resistance limit for the upper spring seat 4 / lower spring seat 6.

[0032] like Figure 3 and Figure 4 As shown, as a preferred solution, a guide ring 14 is fixed to the lower end of the pull rod 1, and a sliding fit is formed between the outer peripheral wall of the guide ring 14 and the inner wall of the insertion cavity 21. The setting of the guide ring 14 can provide good guidance for the pull rod 1 when it moves up and down, so that the pull rod 1 and the sleeve 2 can be flexible and stable in telescopic activities, and the control accuracy can be improved.

[0033] In some embodiments, the magnet 11 is annular and is sleeved on the lower end of the pull rod 1. The outer diameter of the magnet 11 is smaller than the outer diameter of the guide ring 14 to prevent friction between the magnet 11 and the inner wall of the insertion cavity 21 when the pull rod 1 moves up and down.

[0034] like Figure 3 and Figure 4 As shown, a mounting groove 26 is provided on the side of the mounting base 23 facing away from the sleeve 2. The circuit board 24 is fixed in the mounting groove 26 and covered with a sealant. The circuit board 24 is covered with the sealant to prevent water from contacting the circuit board 24. The Hall element 25 is arranged toward the inside of the sleeve 2 to ensure the sensing sensitivity of the Hall element 25.

[0035] In some embodiments, a sealing ring 9 is provided between the pull rod 1 and the stop sleeve 3. The sealing ring 9 can prevent water and dust from entering the sleeve 2 through the gap between the pull rod 1 and the stop sleeve 3, thereby ensuring the stability of the shifting mechanism; the stop sleeve 3 and the sleeve are screwed and fixed, so that the stop sleeve 3 and the sleeve are reliably connected.

[0036] In order to better adapt to the installation of the shift mechanism, such as Figure 1 and Figure 3As shown, the upper end of the pull rod 1 is an external threaded column structure, and the lower end of the sleeve 2 is an internal threaded hole structure. In actual operation, the lower end of the sleeve 2 can also be set to an external threaded column structure to adapt to the fixed connection with the external component.

[0037] like Figure 3 As shown, a wire protection sleeve 8 is fixed on the mounting seat 23, and a wire hole is provided on the wire protection sleeve 8 for the wire to pass through. The wire connected to the circuit board 24 passes through the wire hole. The wire protection sleeve 8 can protect the wire. A clip 81 is installed on the outside of the wire protection sleeve 8. After the wire passes through the wire protection sleeve 8, the wire protection sleeve 8 is clamped from the outside by the clip 81 so that the hole wall is close to the outer wall of the wire after the wire hole is reduced. On the one hand, it can fix the wire and prevent the wire from being easily loosened by external force. On the other hand, it can prevent water from entering the inside of the mounting seat 23 through the wire hole. The wire protection sleeve 8 can be a rubber sleeve or a silicone sleeve.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
