Description

Technical Field

[0001] This invention relates to the field of teaching demonstration equipment technology, and in particular to a mobile demonstration device for legal cases. Background Technology

[0002] Mobile legal case demonstration devices are high-tech portable equipment designed specifically for court trials, legal education, and case discussions. They typically integrate a high-definition touchscreen display, a wireless projection system, and pre-installed legal visualization software. They can present complex case timelines, relationship diagrams, evidence chains, and 3D reconstructions of crime scenes in a dynamic and interactive manner. The device allows lawyers or judges to annotate, zoom, and retrieve electronic case files in real time during trials, effectively solving the pain points of inconvenient access to traditional paper materials and the difficulty in clarifying complex logic with static charts. This greatly improves the efficiency of fact-finding, enhances the persuasiveness of courtroom arguments, and promotes the digital and intelligent transformation of the judicial process.

[0003] Currently, although mobile legal case demonstration devices have been initially applied, their structural design still has significant limitations. Traditional displays are usually fixed to a specific position on a mobile stand, resulting in a single and non-adjustable screen orientation. This makes it difficult to meet the needs of multiple people sitting around for discussions or displaying cases from different standing positions. It can easily cause some observers' lines of sight to be obstructed or cause glare. At the same time, such devices lack a flexible height adjustment mechanism and cannot adaptively adjust to different usage states such as user height differences, standing to explain, or sitting to watch. This not only reduces the efficiency of information transmission and interactive experience, but also easily causes visual fatigue when viewed from an uncomfortable angle for a long time.

[0004] Therefore, there is an urgent need for a new type of mobile legal case demonstration device with adjustable angle and height to overcome the shortcomings of existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile demonstration device for legal cases, which solves the problems of existing mobile legal case demonstration devices, which have fixed screen orientation and lack of flexible height adjustment mechanism, making it difficult to meet the needs of multi-angle display, easily causing obstructed vision and glare interference, and failing to adapt to different user postures, thus reducing information transmission efficiency and causing visual fatigue.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0007] A mobile demonstration device for legal cases, characterized in that it comprises: a base, an angle adjustment mechanism, and a height adjustment mechanism;

[0008] The base includes a slide, which is fitted inside the base;

[0009] The angle adjustment mechanism includes a fixed frame, a connecting frame, a half gear, a sleeve, and a rack;

[0010] The connecting frame is fixedly installed on the fixed frame, and the fixed frame is sleeved on the sleeve rod.

[0011] The angle adjustment mechanism facilitates the adjustment of the display screen on the demonstration device, while the height adjustment mechanism allows for height adjustment of the entire device, making it easier for users to view the device.

[0012] The mounting bracket facilitates the secure installation of the display screen on the demonstration device, ensuring the stability of the screen installation. The bracket can also be mounted on the sleeve rod, and in special circumstances, it can be removed from the sleeve rod. The connecting bracket is fixed to the mounting bracket with bolts and nuts, ensuring the stability of the connecting bracket installation. This also facilitates the installation of the gear rack. The half-gear design allows for angle changes based on the rotation of the gear rack; therefore, the rotation of the half-gear drives the sleeve rod to rotate.

[0013] As an improvement, the sleeve is fixedly installed on the half gear, and the half gear meshes with the rack.

[0014] The rack and pinion mechanism allows for sliding when the handle is pushed, which in turn facilitates the rotation of the half gear. Furthermore, the rack and pinion are self-locking, effectively preventing the half gear from rotating with minimal force.

[0015] As an improvement, the rack is slidably mounted on a connecting frame, and the connecting frame has a groove that matches the rack.

[0016] As an improvement, a handle is installed at the rear end of the rack, and a square groove matching the handle is cut into the connecting frame.

[0017] As an improvement, the angle adjustment mechanism further includes a connector, on which the half gear is rotatably mounted.

[0018] The connector facilitates the rotational installation of the half gear and also makes it easy to connect with the sleeve, allowing the half gear to be associated with the height adjustment mechanism.

[0019] As an improvement, the height adjustment mechanism includes a sleeve, a threaded rod, and a motor.

[0020] As an improvement, the sleeve is fixedly installed under the connector, and the sleeve passes through the slide.

[0021] The sleeve design facilitates the upward movement of the screw rod, thus enabling the operation of the angle adjustment mechanism and the display screen, and effectively adjusting the height of the display screen.

[0022] As an improvement, the sleeve is fixedly mounted on the slide, and the threaded rod is rotatably mounted on the base.

[0023] The threaded rod is designed to rotate according to the rotation of the motor, thus enabling the threaded rod to drive the lifting and lowering of the sleeve.

[0024] As an improvement, the sleeve is fitted onto the threaded rod, and the sleeve matches the threaded rod.

[0025] As an improvement, the motor is fixedly mounted on the base, the motor passes through the base and is connected to the threaded rod, and the base is provided with a limiting groove that matches the slide.

[0026] The beneficial effects of this invention are as follows: by setting up an angle adjustment mechanism and a height adjustment mechanism, the viewing angle and height of the display screen can be flexibly adjusted to meet the viewing needs of different users, avoid obstruction of vision and reflection interference, improve the multi-angle display effect, effectively improve information transmission efficiency, improve interactive experience, reduce visual fatigue, and have a stable structure and convenient operation, making it suitable for various court hearings and teaching scenarios.

[0032] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0033] like Figures 1 to 2 As shown, a mobile demonstration device for legal cases is characterized by comprising: a base 1, an angle adjustment mechanism 2, and a height adjustment mechanism 3; the base 1 includes a slide 101, which is sleeved within the base 1; the angle adjustment mechanism 2 includes a fixing frame 201, a connecting frame 202, a half gear 203, a sleeve rod 204, and a toothed rod 205; the connecting frame 202 is fixedly installed on the fixing frame 201, and the fixing frame 201 is sleeved on the sleeve rod 204.

[0034] The angle adjustment mechanism 2 facilitates angle adjustment of the display screen on the demonstration device, while the height adjustment mechanism 3 allows for height adjustment of the entire device, improving user viewing comfort. The mounting bracket 201 ensures stable installation of the display screen and allows it to be mounted on the sleeve rod 204. In special circumstances, the bracket 201 can be detached from the sleeve rod 204. The connecting bracket 202 is fixed to the mounting bracket 201 with bolts and nuts, ensuring stability and facilitating the installation of the gear 205. The half-gear 203 allows for angle changes based on the rotation of the gear 205, thus rotating the sleeve rod 204.

[0035] The sleeve 204 is fixedly mounted on the half gear 203, and the half gear 203 meshes with the rack 205. The rack 205 is slidably mounted on the connecting frame 202, and the connecting frame 202 has a groove that matches the rack 205. A handle is mounted on the rear end of the rack 205, and the connecting frame 202 has a square groove that matches the handle. The angle adjustment mechanism 2 also includes a connecting member 206, and the half gear 203 is rotatably mounted on the connecting member 206.

[0036] The rack 205 is designed to slide smoothly when the handle is pushed, thus facilitating the rotation of the half gear 203. Furthermore, the rack 205 and half gear 203 are self-locking, effectively preventing the half gear 203 from rotating with minimal force. The connector 206 facilitates the rotatable installation of the half gear 203 and allows for connection to the sleeve 301, enabling the half gear 203 to be associated with the height adjustment mechanism 3.

[0037] The height adjustment mechanism 3 includes a sleeve 301, a threaded rod 302, and a motor 303. The sleeve 301 is fixedly installed under the connector 206 and passes through the slide 101. The sleeve 301 is fixedly installed on the slide 101, and the threaded rod 302 is rotatably installed on the base 1.

[0038] The sleeve 301 is designed to facilitate upward movement based on the rotation of the threaded rod 302, thus enabling the operation of the angle adjustment mechanism 2 and the display screen, and effectively adjusting the height of the display screen. The threaded rod 302 is also designed to rotate based on the rotation of the motor 303, thereby driving the sleeve 301 to rise and fall.

[0039] The sleeve 301 is fitted onto the threaded rod 302, and the sleeve 301 matches the threaded rod 302. The motor 303 is fixedly installed on the base 1, and the motor 303 passes through the base 1 and is connected to the threaded rod 302. The base 1 has a limiting groove that matches the slide 101.

[0040] During implementation, the display screen on the demonstration device is fixedly installed on the mounting bracket 201. If height adjustment is required, the motor 303 is started to drive the threaded rod 302 to rotate. When the threaded rod 302 rotates, it will drive the sleeve 301 to move and rise. Therefore, during the rising process, the height of the display screen and the angle adjustment mechanism 2 will be adjusted. After adjusting to the appropriate position, the motor 303 can be stopped. If the angle of the display screen needs to be adjusted during the case demonstration, the handle on the rack 205 can be manually pushed. Therefore, the rack 205 will slide on the connecting bracket 202. During the sliding process, the rack 205 will drive the half gear 203 to rotate. Therefore, when the half gear 203 rotates, it will drive the sleeve 204. Therefore, the sleeve 204 will drive the mounting bracket 201 to achieve angle adjustment, and thus the display screen will also be angled.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
