[0003] An electric trolley case is a trolley case that achieves automatic movement by adding an electric assist device. For related structures, please refer to Chinese Utility Model Publication No. CN209346219U, entitled "Dual-Wheel Electric Trolley Case," which describes: "A dual-wheel electric trolley case includes at least: a retractable trolley rod, a trolley case body, an electric control chip, and rollers disposed on both sides of the rear of the trolley case body; a control handle with a control switch is disposed above the retractable trolley rod; the electric control chip includes: a central control module for main control, a status monitoring module for detecting the status of the trolley case, a status display module disposed above the trolley case for displaying the status, a motor drive module for controlling the motor, a status control module for receiving signals from the motor drive module to control the trolley case, and a power supply module for supplying power to the above modules." The control handle is disposed at the upper end of the retractable trolley rod, and the control handle needs to be connected to the main control module via a wire. However, since the tie rod is a telescopic component, when it is installed inside, the wires are not telescopic and are prone to positional interference and friction with the tie rod. This not only affects the smoothness of the tie rod's extension and retraction but also causes wear on the wires, resulting in a relatively short service life. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a steering signal transmission guide rail mechanism and an electric luggage case that can avoid interference between the wire and the pull rod, ensure smooth extension and retraction of the pull rod, and have higher electrical connection reliability.

[0005] The technical solution adopted in this application is as follows:

[0006] A steering signal transmission guide mechanism includes a tie rod sleeve, a tie rod, and a steering control plate. The tie rod is inserted into the tie rod sleeve, and the two slide vertically together.

[0007] A probe plate is fixed on the outer wall of the pull rod, and a probe is provided on the probe plate. The probe is electrically connected to the steering control board.

[0008] An electrical contact rail extending along its length is fixed on the inner wall of the pull rod sleeve. The electrical contact rail corresponds to and abuts against the probe. The electrical contact rail is electrically connected to the main control board.

[0009] The probe moves with the pull rod, causing the probe to slide onto the electrical contact rail.

[0010] Furthermore, it also includes a handle, which is fixed to the upper end of the pull rod, the steering control plate is disposed inside the handle, and the handle is provided with a steering control device electrically connected to the steering control plate.

[0011] Furthermore, a strip-shaped guide rail extending along its length is fixed on the inner wall of the pull rod sleeve, and the electrical contact rail is disposed on the strip-shaped guide rail and extends along the length of the strip-shaped guide rail.

[0012] Furthermore, a wire is threaded through the pull rod, and the wire is electrically connected between the probe and the steering control panel.

[0013] Furthermore, the outer wall of the pull rod is provided with a first receiving groove, and the probe plate is fixed in the first receiving groove.

[0014] Furthermore, the inner wall of the pull rod sleeve is provided with a second receiving groove extending along its length, and the strip guide rail is embedded in the second receiving groove.

[0015] Furthermore, the probe plate is fixed to the lower end of the pull rod.

[0016] Furthermore, the probe plate is provided with two probes that are electrically connected to the steering control board, and there are two electrical contact rails, which correspond one-to-one with the probes.

[0017] An electric luggage case includes the steering signal transmission guide rail mechanism described in any one of the above claims.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] The steering signal transmission guide rail mechanism provided in this application includes a pull rod sleeve, a pull rod, and a steering control plate. The pull rod is inserted into the pull rod sleeve, and the two slide vertically together, thus realizing the basic structure of the telescopic pull rod. On this basis, this application provides an electric contact rail on the inner side wall of the pull rod sleeve, and the electric contact rail is electrically connected to the main control plate. Correspondingly, a probe plate is fixed on the outer wall of the pull rod. The probe on the probe plate keeps in contact with the electric contact rail. Since the probe is electrically connected to the steering control plate, an electrical connection path is formed between the steering control plate and the main control plate. The user can send a steering control signal to the main control plate by operating the steering control device. At the same time, since the electric contact rail extends along the length of the pull rod sleeve, the probe can keep in contact with the electric contact rail in real time when the user pulls the pull rod. Compared with the connection method using wires in the prior art, this application can avoid positional interference between the excessively long wire and the pull rod, which can not only ensure the smooth extension and retraction of the pull rod, but also make the electrical connection more reliable, thus better meeting the application requirements.

[0026] The technical solutions in 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 protection scope of the present invention.

[0027] The present application will now be discussed in detail with reference to Figures 1 to 5 and specific embodiments.

[0028] This application discloses a steering signal transmission guide mechanism, which can be applied to electric luggage boxes, scooters, and other structures involving steering. Referring to Figures 1 to 5, it includes a pull rod sleeve 1, a pull rod 2, and a handle 3. The pull rod 2 is inserted into the pull rod sleeve 1, and the two slide vertically together. The handle 3 is fixed to the upper end of the pull rod 2. A steering control plate 30 is provided inside the handle 3, and a steering control device 31 electrically connected to the steering control plate 30 is provided on the handle 3. A probe plate is fixed to the outer wall of the pull rod 2. 4. The probe plate 4 is located at the lower end of the pull rod 2. The probe plate 4 has two probes 40 electrically connected to the steering control board 30. A strip-shaped guide rail 5 is fixed to the inner wall of the pull rod sleeve 1. The strip-shaped guide rail 5 extends along the length of the pull rod sleeve 1. Two electrical contact rails are provided on the strip-shaped guide rail 5, extending along the length of the strip-shaped guide rail 5. The probes 40 correspond one-to-one with the electrical contact rails and abut against each other. The electrical contact rails are electrically connected to the main control board of the electric luggage compartment. It should be noted that this application does not limit the specific structure of the handle 3. For example, the handle 3 can be a straight rod symmetrically arranged on both sides of the pull rod 2, or it can be a steering wheel or other structures. This application uses the example of a handle 3 being a straight rod symmetrically arranged on both sides of the pull rod 2 for illustration.

[0029] In the above structure, the handle 3 is fixed to the upper end of the pull rod 2, and the lower end of the pull rod 2 is inserted into the pull rod sleeve 1, with the two sliding together vertically, thus realizing the basic mechanism of the telescopic pull rod. Based on this, a strip guide rail 5 is fixed to the inner wall of the pull rod sleeve 1. Two electrical contact rails on the strip guide rail 5 are electrically connected to the main control board of the electric luggage compartment. Correspondingly, a probe plate 4 is fixed to the outer wall of the pull rod 2. Two probes 40 on the probe plate 4 abut against the two electrical contact rails respectively. Because the two probes 40 are electrically connected to the steering control board 30, an electrical connection path is formed between the steering control board 30 and the main control board of the electric luggage compartment. The user can send a steering control signal to the main control board by operating the steering control device 31. Because the strip guide rail 5 extends along the length of the pull rod sleeve 1, when the user holds the handle 3 and pulls the pull rod 2... The two probes 40 can maintain contact with the two electrical contact rails in real time. Compared with the connection method using wires in the prior art, this application can avoid positional interference between the excessively long wires and the pull rod 2, which can not only ensure the smooth extension and retraction of the pull rod, but also make the electrical connection more reliable, thus better meeting the application requirements.

[0030] In this embodiment, a wire is threaded through the pull rod 2, and the wire is electrically connected between the two probes 40 and the steering control plate 30. The wire inside the pull rod 2 is unaffected by the extension or retraction of the pull rod 2 and is only used to connect the two probes 40 and the steering control plate 30.

[0031] To ensure a smooth outer surface of the pull rod 2, this embodiment preferably hides the probe plate 4. As shown in Figure 1, the outer side wall of the pull rod 2 has a first receiving groove 20, and the probe plate 4 is fixed within the first receiving groove 20.

[0032] Please refer to Figure 3. To prevent the strip guide rail 5 from protruding outward, in this embodiment, a second receiving groove 10 is provided on the inner sidewall of the pull rod sleeve 1, and the strip guide rail 5 is embedded in the second receiving groove 10. In practical applications, both electrical contact rails run longitudinally through the upper and lower ends of the strip guide rail 5. The electrical contact rails can be copper-clad plates printed on the strip guide rail 5, or they can be metal conductive strips embedded in the strip guide rail 5.

[0033] To achieve the limiting engagement function between the pull rod 2 and the pull rod sleeve 1, in this embodiment, the top of the handle 3 is provided with an elastic button 32, the lower end of the elastic button 32 is connected to a limiting rod 33, the lower end of the pull rod 2 is fixed with a support 21, the support 21 is provided with a slider 22 that can slide elastically laterally, the end of the slider 22 is provided with a limiting end 23, the limiting end 23 passes through the support 21 and the side wall of the pull rod 2 in sequence, the pull rod sleeve 1 is provided with a limiting hole 11 for the limiting end 23 to pass through, the top of the slider 22 is provided with a wedge-shaped notch 24, the lower end of the limiting rod 33 is fixed with a wedge-shaped tongue 34, the wedge-shaped tongue 34 and the wedge-shaped notch 24 are vertically aligned and their inclined surfaces are opposite each other, when the elastic button 32 is pressed, the limiting rod 33 and the wedge-shaped tongue 34 are driven to move downward. The inclined surface of the wedge tongue 34 contacts the inclined surface of the wedge recess 24, causing the slider 22 to retract into the support 21. When the elastic button 32 is released, the slider 22 elastically slides outward so that the limiting end 23 passes through the limiting hole 11.

[0034] Furthermore, the support 21 is provided with a spring 25, which elastically abuts against the end of the slider 22 away from the limiting end 23.

[0035] In the above mechanism, when the user does not press the elastic button 32, the spring 25 applies a lateral elastic force to the slider 22, causing the slider 22 to slide outward. The limiting end 23 can abut against the inner recess of the pull rod sleeve 1. When the pull rod 2 is stretched to the end and the limiting hole 11 is aligned with the limiting end 23, the limiting end 23 passes through the limiting hole 11 and achieves the limiting function. When the user presses the elastic button 32, the wedge tongue 34, through its cooperation with the wedge recess 24, drives the slider 22 to slide inward, and the limiting end 23 exits from the limiting hole 11. At this time, the pull rod 2 can slide up and down. Based on the above principle, this application implements the telescopic limiting function of the pull rod 2 with a simple and reliable component.

[0036] In practical applications, the pull rod sleeve 1 is provided with two limiting holes 11, which allow the pull rod 2 to be locked at two different length positions, thus satisfying the purpose of pull rod retraction and extension.
