Description

Technical Field

[0001] This utility model relates to the field of LCD instrument connection cable technology, and in particular to an intelligent LCD instrument with a stable connection cable. Background Technology

[0002] With the continuous development of intelligent technologies, intelligent LCD instruments, with their advantages of high-precision data display and multi-functional integration, are widely used in many fields such as automobiles, industrial control, and smart homes. Intelligent LCD instruments need to be connected to external devices such as power supplies, sensors, and control modules via connecting cables to achieve functions such as power supply and data transmission. The stability of these connecting cables directly affects the reliability of the instrument's operation.

[0003] However, most smart LCD instruments currently on the market still use traditional plug-in connections or simple snap-on connection cables. These methods pose significant risks in complex usage scenarios. Plug-in connections rely solely on the connection between interfaces. When an electric vehicle travels on bumpy roads, the vibrations from the road surface constantly impact the connection cable. The mechanical stress generated by prolonged vibration gradually weakens the friction between the interfaces, causing the connection cable to loosen frequently, and in severe cases, detach completely. This results in power outages, abnormal data transmission, and affects the normal operation of the device. Therefore, it is necessary to design a smart LCD instrument with a stable connection cable.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a smart LCD instrument with a stable connection cable to solve the problem that most smart LCD instruments use traditional plug-and-play fixed connection cables, which are prone to loosening and falling off in scenarios such as bumps and vibrations in electric vehicles.

[0006] This utility model embodiment adopts the following technical solution: a smart LCD instrument with a stable connection via a connecting cable. It mainly includes a smart LCD instrument body, which includes a control box with terminals on its side; a reinforcement component, which is disposed on the side of the control box, the reinforcement component including a connector mounted on the side of the control box, the vertical section of the connector having a detachable limiting part, the limiting part being a concave structure, two sets of hooks mounted at the opening of the limiting part, a rotating shaft rotatably disposed within the two sets of hooks, vertically distributed contact protrusions on a localized portion of the hook surface, a handle fixed on the rotating shaft, and a portable component installed on the limiting part to prevent damage to the connecting cable harness and cable ends from pulling.

[0007] Furthermore, openings are provided on all three sides of the limiting part.

[0008] Furthermore, the portable component is embedded on both sides of the inner wall of the symmetrically arranged opening slot. The portable component includes guide rods embedded on both sides of the inner wall of the opening slot. Hollow T-shaped sliding grooves are opened on the opposing surfaces of the guide rods. A sliding part is slidably arranged in the T-shaped sliding groove. One end of the sliding part is connected to a connecting rod. The connecting rod has a downwardly extending protrusion. A notch is opened at the corresponding position of the control box.

[0009] Furthermore, a handle is fixedly connected to the protrusion.

[0010] Furthermore, the limiting part adopts a concave structure.

[0011] Furthermore, the limiting part has two sets of right-angled parts on the side near the connector. The right-angled parts are L-shaped, and a precise installation distance is formed between the two sets of right-angled parts, which constitutes a sliding guide rail structure.

[0012] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0013] A smart LCD instrument with a stable connection cable utilizes a concave limiting part in conjunction with a hook holding part, a rotating shaft, and a handle structure. By rotating the handle, the anti-slip textured contact protrusions encircle the connecting cable, employing both mechanical limiting and frictional force to resist external vibration and prevent loosening and detachment. The anti-detachment closed-loop structure of the hook holding part ensures the stability of the rotating shaft. Simultaneously, the portable component on the limiting part applies uniform external force to the connecting cable connector via the handle during insertion and removal, preventing damage to the cable harness and cable ends. The opening slot also serves as an operating and heat dissipation function. Attached Figure Description

Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-4 As shown, this embodiment of the present invention provides an intelligent LCD instrument with a stable connection via a connecting cable, including an intelligent LCD instrument body 1. The intelligent LCD instrument body 1 consists of a control box 11 and a display 12, which are tightly integrated through an integrated design. The control box 11 houses core components such as a main control chip, sensor interfaces, and data processing circuits, undertaking information acquisition, processing, and command transmission functions; the display 12 uses a high-definition LCD screen to intuitively display operating data such as vehicle or equipment speed, battery level, and fault alarms.

[0026] Furthermore, a terminal block 13 is provided on the side of the control box 11. This terminal block 13 is designed for connecting the cable 15 and adopts a standardized interface specification, supporting the connection of various cables 15 such as power cables and data cables.

[0027] A reinforcing component 2 is provided on the side of the control box 11 at the terminal 13 to improve the stability of the connecting wire 15. The reinforcing component 2 includes a connector 21 fixedly installed on the side of the control box 11, and a limiting part 22 is fixedly installed on the vertical section of the connector 21. The limiting part 22 has two sets of right-angled parts 27 integrated on the side of the connector 21. The right-angled parts 27 are L-shaped and form a precise installation distance between each pair, forming a sliding guide rail structure.

[0028] To ensure that the limiting part 22 can slide smoothly along the vertical direction of the connector 21, during installation, the height and position of the limiting part 22 on the connector 21 can be flexibly adjusted according to the actual needs such as the thickness of different specifications of the connecting wires 15 and the wiring position, so as to achieve a fit. After the limiting part 22 is adjusted to the ideal position, the limiting part 22 and the connector 21 can be firmly locked by fasteners such as bolts and nuts through the mounting holes reserved in the right angle part 27, so as to ensure that the limiting part 22 will not be displaced due to vibration during equipment operation, and continuously provide reliable limiting and protection for the connecting wires 15;

[0029] The limiting part 22 has a concave structure and is aligned linearly with the terminal 13, effectively guiding the insertion path of the connecting wire 15 and preventing deviation. The concave design of the limiting part 22 perfectly fits the connection area between the terminal 13 and the connecting wire 15, providing initial positioning for the connecting wire 15. Two sets of hook-holding parts 23 are integrally formed at their openings, with the curvature of the hook-holding parts 23 forming a robust anti-detachment closed-loop structure. A rotating shaft 24 is rotatably installed within the two sets of hook-holding parts 23. Vertical contact protrusions 241 are vertically distributed on a portion of the surface of the hook-holding parts 23, made of wear-resistant and anti-slip material with a serrated texture to enhance friction with the connector surface of the connecting wire 15.

[0030] A handle 25 is vertically fixed on the rotating shaft 24, featuring an ergonomic design and a surface covered with anti-slip rubber. During use, the operator first passes the connecting cable 15 through the concave channel of the limiting part 22, guiding it to the connector 13 for insertion. Then, by gently gripping the handle 25 and rotating it along the axis, the rotating shaft 24 rotates accordingly, and the regularly distributed contact protrusions 241 on the surface gradually approach the side of the connector 15. These contact protrusions 241 are made of wear-resistant silicone material with a wavy anti-slip texture, allowing them to adaptively deform and conform to the diameter of the connecting cable 15.

[0031] As the handle 25 continues to rotate, the contact protrusion 241 forms a wrap-around clamp on the connecting cable 15. This not only counteracts the tension generated by external vibration through mechanical limiting, but also utilizes the friction between the protrusion and the connecting cable 15 to achieve a double anti-loosening effect, ensuring that the connecting cable 15 remains firmly connected under extreme working conditions such as vibration and severe bumps, eliminating the risk of loosening and falling off.

[0032] To address the issue of damage to the wire harness and wire ends when connecting cable 15 is plugged in or unplugged from terminal 13, refer to... Figures 3-5 As shown, opening slots 26 are provided on three sides of the limiting part 22, which not only provide heat dissipation channels for the connecting line 15, but also facilitate the reservation of operating space. For the symmetrical opening slots 26, portable components 3 are embedded on both sides of the inner wall of the opening slots 26. The portable components 3 include guide rods 31 embedded on both sides of the inner wall of the opening slots 26, and hollow T-shaped sliding grooves are opened on the facing surfaces of the guide rods 31.

[0033] Furthermore, a sliding part 33 is slidably provided in the T-shaped slide groove, wherein the T-shaped slide groove provides guidance, the sliding part 33 is adapted to the T-shaped slide groove and can slide smoothly, one end of the sliding part 33 is connected to a connecting rod 34, the connecting rod 34 is provided with a downwardly extending protrusion 35, and the control box 11 is provided with a notch 14 at the corresponding position to accommodate the protrusion 35, ensuring that the overall structure of the equipment is compact.

[0034] The protrusion 35 can fit into the connector of the connecting wire 15 to achieve flexible positioning. A handle 36 is fixedly connected to the protrusion 35. When it is necessary to pull out the connecting wire 15, the operator holds the handle 36 fixed to the protrusion 35 and drives the protrusion 35 to slide in a straight line along the T-shaped groove. The protrusion 35 applies a uniform external force to help pull out the connected wire 15 smoothly, avoiding damage to the wire harness and wire ends due to uneven force application, and improving the safety and convenience of the insertion and removal operation.

[0035] Working principle: During the equipment installation phase, the operator slides the limiting part 22 vertically along the connector 21 according to the specifications of the connecting wire 15 and the actual wiring requirements. Using the sliding guide rail structure formed by the right-angle part 27 and the connector 21, the limiting part 22 is adjusted to a suitable position. Then, the limiting part 22 and the connector 21 are locked by fasteners passing through the reserved holes of the right-angle part 27.

[0036] Subsequently, the connecting cable 15 is passed through the concave channel of the limiting part 22 and inserted into the wiring terminal 13 on the side of the control box 11. At this time, rotating the handle 25 drives the rotating shaft 24 to rotate, and the contact protrusions 241 with serrated texture and wavy anti-slip texture on the surface of the rotating shaft 24 gradually approach the side of the connector of the connecting cable 15. As the handle 25 continues to rotate, the contact protrusions 241 surround the connecting cable 15, using mechanical limiting and friction to double offset the external forces generated by vibration and bumps during equipment operation, ensuring that the connecting cable 15 is stable and does not fall off. At the same time, the anti-detachment closed-loop structure of the hook part 23 prevents the rotating shaft 24 from accidentally falling off, ensuring the reliability of the fixing structure. In this application, the end of the connecting cable 15 has a step. It is worth noting that the protrusion 35 moves synchronously during the insertion of the connecting cable 15, closely fitting the step structure of the end of the connecting cable 15 and embedding it into the notch 14 of the control box 11. The protrusion 35 is in close contact with the upper surface of the step without applying additional pressure, which serves as an auxiliary positioning function and does not affect the electrical connection between the connecting line 15 and the terminal 13, thus ensuring the normal operation of the equipment.

[0037] When it is necessary to remove the connecting wire 15, the operator holds the handle 36 connected to the connecting rod 34. Since the hollow T-shaped groove of the guide rod 31 provides precise guidance for the sliding part 33, pulling the handle 36 causes the protrusion 35 to slide linearly along the groove. The protrusion 35 moves accordingly, fitting against the connector of the connecting wire 15 and applying uniform external force, smoothly pulling the connecting wire 15 out of the terminal 13, avoiding damage to the wire harness and wire ends due to uneven force application. During the insertion of the connecting wire 15, the concave structure of the limiting part 22 provides initial positioning for the connecting wire 15, and the open slot 26 not only provides operating space but also assists in heat dissipation of the connecting wire 15, ensuring safe and convenient insertion and removal operations without affecting the normal operation of the equipment.

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.
