It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] The following description, with reference to the accompanying drawings, describes a vehicle-mounted display and operating machinery according to the present invention. Figure 1 The diagram shown is a structural schematic of an in-vehicle display provided according to an embodiment of the present invention.

[0020] The vehicle-mounted display provided in this embodiment is used for operating machinery, and the vehicle-mounted display includes: The front shell 10 has a first mounting groove (not shown in the figure) on one side. Multiple positioning posts are also installed at each vertex of the bottom wall of the first mounting groove, and the top of each positioning post has a first locking hole. The display assembly 20 is covered on the side of the front housing 10 opposite to the first mounting groove. The display assembly 20 includes a touch cover plate, which is made of aluminosilicate glass. The rear housing assembly includes a rear housing 31, which covers the first mounting groove to close the first mounting groove. Multiple positioning posts extend toward the rear housing 31, and multiple positioning holes are provided at multiple vertices of the rear housing 31. The multiple positioning holes are configured to correspond one-to-one with the multiple positioning posts. Multiple locking elements 40, each locking element 40 is used to sequentially pass through the positioning hole and the locking hole to lock the rear housing 31 and the front housing 10.

[0021] In the prior art, vehicle-mounted displays used in construction machinery typically employ a multi-layered assembly structure to ensure their protective performance, thereby enabling the displays to function properly in harsh working environments. However, multi-layered vehicle-mounted displays are excessively heavy, which does not meet the usage requirements of small and medium-sized construction machinery.

[0022] The vehicle-mounted display provided in this embodiment includes a front housing 10, a display screen assembly 20, a rear housing assembly, and multiple locking components 40. The front housing 10 has a first mounting groove on one side, and multiple positioning posts are installed at each vertices of the bottom wall of the first mounting groove. The rear housing 31 of the rear housing assembly covers the first mounting groove, and multiple positioning holes are correspondingly provided at multiple vertices of the rear housing 31, with each positioning hole corresponding to a positioning post. Each locking component 40 passes through a positioning hole and a locking hole in sequence, thereby securely locking the rear housing 31 to the front housing 10. This design not only simplifies the assembly structure but also significantly reduces the overall weight and size of the vehicle-mounted display. Furthermore, the touch cover of the display screen assembly 20 is made of aluminosilicate glass, a material with high strength, high hardness, and relatively light weight, which helps to achieve a lightweight design for the vehicle-mounted display.

[0023] In one embodiment, both the front housing 10 and the rear housing 31 are made of magnesium alloy or plastic. Both magnesium alloy and plastic materials possess excellent shock absorption properties and are relatively lightweight, effectively reducing the overall weight of the vehicle display compared to traditional aluminum alloys, while simultaneously meeting vibration resistance and protection requirements. By employing either of these materials, the vehicle display achieves a lightweight design goal while maintaining high performance. In practical applications, the material selection for the front housing 10 and the rear housing 31 can be flexibly adjusted according to specific usage requirements and cost considerations. For example, magnesium alloy can be chosen for applications requiring higher strength and rigidity, while plastic materials can be selected for cost-sensitive applications. In a specific embodiment, the plastic material can be polyetheretherketone (PEEK) or polyphenylene oxide (PPO).

[0024] In one embodiment, such as Figure 1 As shown, the rear housing assembly also includes a first sealing ring 32 and a second sealing ring 33. The first sealing ring 32 is attached to the inner sidewall and bottom wall of the first mounting groove, and the second sealing ring 33 is attached to the bottom wall of the first mounting groove. The second sealing ring 33 is located inside the first sealing ring 32, and a plurality of clearance rings for clearance positioning posts are formed between the first sealing ring 32 and the second sealing ring 33. The first sealing ring 32 and the second sealing ring 33 are used to seal the gap between the front housing 10 and the rear housing 31. The first mounting groove can be used to install electronic components. Therefore, it is necessary to ensure that the first mounting groove is sealed from the outside world to prevent external dust and water droplets from entering the first mounting groove and damaging the electronic components. In the rear housing assembly of this embodiment, a first sealing ring 32 and a second sealing ring 33 are provided. The first sealing ring 32 is attached to the inner sidewall and bottom wall of the first mounting groove, and the second sealing ring 33 is attached to the bottom wall of the first mounting groove and located inside the first sealing ring 32. A clearance ring for clearance positioning posts is formed between the two, thereby achieving effective sealing of the gap between the front housing 10 and the rear housing 31. This sealing structure not only prevents dust, water droplets, and other external substances from entering the first mounting groove, protecting the internal electronic components from damage, but also enhances the overall protective performance of the vehicle display to a certain extent. In practical applications, the materials of the first sealing ring 32 and the second sealing ring 33 can be selected according to specific needs, such as rubber or silicone, which have good elasticity and sealing performance, to ensure the reliability and durability of the sealing effect.

[0025] In one embodiment, such as Figure 1As shown, both the first sealing ring 32 and the second sealing ring 33 are open-type sealing rings, and their openings are staggered. This staggered arrangement of the openings of the first sealing ring 32 and the second sealing ring 33 further improves the reliability of the seal. Even if one sealing ring has a minor defect or is affected by external forces, the other sealing ring can still provide an effective seal, thus ensuring the stable operation of the vehicle display in harsh working environments. In one specific embodiment, the first sealing ring 32 and the second sealing ring 33 are assembled with a 180° offset.

[0026] In one embodiment, the vehicle display further includes a connector assembly and a circuit board assembly 60. The circuit board assembly 60 is mounted in a first mounting slot. The connector assembly includes a socket 51 and a socket housing 52. The socket 51 is mounted on the side of the circuit board assembly 60 opposite to the front housing 10 assembly. The socket 51 includes a base and terminals located on the base. The socket housing 52 is disposed on the side of the rear housing 31 opposite to the circuit board assembly 60. The socket housing 52 is fitted around the base of the socket 51, and its central portion is open to allow passage of the terminals on the socket 51. The design of the socket 51 ensures a stable connection between the circuit board assembly 60 and external devices, while the socket housing 52 protects the socket 51 and terminals from damage by the external environment.

[0027] In one embodiment, the socket 51 is a multi-pin vertical socket, and the pins of the multi-pin vertical socket are soldered to the circuit board assembly 60.

[0028] In one embodiment, a support rod 11 is also provided in the first mounting slot. The support rod 11 is used to support the circuit board assembly 60 and ensure that the circuit board assembly 60 is snapped into the first mounting slot.

[0029] In one embodiment, a second mounting groove (not shown) is provided circumferentially at the end of the base away from the circuit board assembly 60. A first abutment surface and a second abutment surface are provided at intervals on the inner peripheral wall of the socket housing 52. The connector assembly further includes a third sealing ring (not shown), a plug 53, and a fourth sealing ring (not shown). The third sealing ring is disposed within the second mounting groove and seals against the first abutment surface. The plug 53 is used to connect to the socket 51. A third abutment surface is provided on the side wall of the plug 53, and a third mounting groove (not shown) is provided on the third abutment surface. The fourth sealing ring is installed in the third mounting groove and seals against the second abutment surface.

[0030] To further enhance the protective performance of the connector assembly, this embodiment of the invention includes a third sealing ring within the second mounting groove. The third sealing ring achieves a tight seal with the first contact surface of the inner peripheral wall of the socket housing 52, effectively preventing dust and moisture from entering through the connection between the socket 51 and the socket housing 52, thus protecting the internal circuitry from interference. Simultaneously, when the plug 53 is inserted into the socket 51, the fourth sealing ring contacts the second contact surface, further strengthening the sealing effect at the insertion point. This ensures that the connector assembly can operate stably and reliably in harsh working environments, preventing poor contact or circuit failure due to external factors.

[0031] In one embodiment, such as Figure 1 As shown, the display assembly 20 is bonded to the front housing 10, and a buffer pad 21 is provided between the display assembly 20 and the front housing 10. The adhesive bonding method ensures the stability and reliability of the connection, while avoiding localized stress concentration caused by screws or other fasteners. In a specific embodiment, the front housing 10 has an adhesive groove on the side facing the display assembly 20, containing a highly shear-resistant, unbreakable, elastic, waterproof hot melt adhesive. This adhesive bonding method further reduces the external dimensions of the display assembly 20, thereby reducing the overall size of the vehicle-mounted display. Furthermore, the buffer pad 21 plays a crucial role in shock absorption and cushioning. During the operation of machinery, various vibrations and impacts are inevitable. If these vibrations and impacts are directly transmitted to the display assembly 20, they may cause damage to the display or display abnormalities. The buffer pad 21 effectively absorbs and disperses this vibration and impact energy, reducing the impact on the display assembly 20, extending the lifespan of the display, and ensuring the stability and clarity of the display effect. Furthermore, the display assembly 20 is attached to the front housing 10 from the front using adhesive material, eliminating the need for an additional screen holder and reducing the overall weight. In one specific embodiment, the cushioning pad 21 is made of foam.

[0032] In one embodiment, such as Figure 1As shown, the front housing 10 has an antenna mounting slot (not shown) on the side opposite to the display assembly 20. This slot accommodates the antenna. The vehicle display also includes an antenna cover 22, a sealing cover located on the antenna mounting slot. The antenna cover 22 is made of plastic. As a key component for receiving and transmitting wireless signals, the stability and reliability of the antenna's installation are crucial for the vehicle display. The antenna mounting slot on the front housing 10 provides dedicated space for the antenna, ensuring it is securely installed and preventing displacement or damage due to vibration or impact during machine operation. The antenna cover 22, located on the antenna mounting slot, provides protection. Firstly, it prevents dust, water droplets, and other external substances from entering the antenna mounting slot, protecting the antenna from damage and ensuring stable signal transmission. Secondly, the plastic material of the antenna cover 22 provides excellent elasticity and sealing performance, further enhancing the protection of the antenna. Furthermore, the plastic antenna cover 22 does not interfere with the wireless signal transmission between the antenna and the outside world. In one specific embodiment, the antenna cover 22 is bonded to the back cover with waterproof double-sided adhesive, and there are two antenna mounting slots, two antennas, and two antenna covers 22.

[0033] In one embodiment, multiple reinforcing ribs (not shown in the figure) are provided on the side walls of both the front housing 10 and the rear housing 31. The reinforcing ribs enhance the structural strength of the front housing 10 and the rear housing 31, making them less prone to deformation or damage under external pressure and vibration, thus effectively protecting the normal operation of the internal electronic components and the display assembly 20. On the other hand, they reduce the weight of the front housing 10 and the rear housing 31. Because, while ensuring structural strength, a properly placed set of reinforcing ribs can improve overall rigidity without adding excessive material, thereby contributing to the lightweight design of the vehicle display. In the actual design process, the number, shape, and distribution of the reinforcing ribs can be optimized according to the specific structure of the front housing 10 and the rear housing 31 and the usage requirements to achieve the best strength enhancement effect. For example, more and denser reinforcing ribs can be provided at the edges of the front housing 10 and the rear housing 31 and in areas with higher stress, while the number of reinforcing ribs can be appropriately reduced in areas with relatively lower stress.

[0034] In one embodiment, the vehicle-mounted display further includes a speaker 70, which is mounted in a first mounting slot and electrically connected to the circuit board assembly 60. The speaker 70 provides audio output functionality to the vehicle-mounted display, meeting the needs for playing audio information such as sound prompts and voice navigation during the operation of the machinery.
