Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a GNSS vehicle-mounted terminal installation component. Background Technology

[0002] In construction machinery vehicles, tilt sensors are typically used to acquire real-time position information of the robotic arm and bucket, enabling precise calculation of the bucket's spatial coordinates. This position information is then displayed on a terminal in the cab, assisting operators in accurately completing tasks such as excavation, loading, and leveling. This is particularly suitable for scenarios requiring high precision, such as pipeline laying and foundation excavation.

[0003] The display terminal is installed in the cab via a multi-angle adjustable mounting component for easy observation by the driver. However, its fixation at the joints relies solely on friction, and the vibrations generated during excavator operation can easily cause the mounting component to loosen, ultimately altering the orientation of the display terminal and affecting the driver's observation. Utility Model Content

[0004] The purpose of this invention is to solve the problem of easy loosening of installation components in the prior art, and to propose a GNSS vehicle-mounted terminal installation component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A GNSS vehicle-mounted terminal mounting assembly includes an upper housing and a lower housing. A base and a mounting bracket for fixing a display terminal are respectively mounted on both ends of the upper housing and the lower housing via a rotating assembly. The rotating assembly includes a ball head fixed to the surface of the base or the mounting bracket and a ball socket formed at the upper or lower end of the upper housing and the lower housing. The ball head rotates on the surface of the ball socket. Two sets of limiting assemblies are provided inside the upper housing and the lower housing to limit the movement of the two ball heads respectively.

[0007] In some embodiments, the limiting component includes a sliding sleeve that slides on the inner wall of the lower housing and a limiting plug disposed near one end of the sliding sleeve near the ball head. The ball head has a plurality of insertion holes on its surface, and the spacing between the plurality of insertion holes is the same.

[0008] In some embodiments, the limiting assembly further includes a guide rod that slides on the inner wall of the sleeve and a spring sleeved on the surface of the guide rod for pushing the limiting plug into the socket surface, wherein the limiting plug is fixed to one end of the guide rod near the ball head.

[0009] In some embodiments, the limiting plug includes a connecting plate fixed to the end of the guide rod facing the ball head, and a first insert and a plurality of second inserts fixed to the end of the connecting plate facing the ball head. The first insert is located at the center of the connecting plate and corresponds to the center of the ball head. The distance between the plurality of second inserts and the first insert is the same as the spacing between the plurality of sockets. The diameter of the plurality of second inserts is smaller than the diameter of the socket.

[0010] In some embodiments, the limiting component further includes a transmission component for driving the two sets of sliding sleeves to slide. The transmission component includes a threaded rod threaded to the surface of the upper housing and a slider threaded to the surface of the threaded rod. One end of the slider slides on the surface of the sliding rod, and the other end of the slider is hinged to a connecting rod. The other end of the connecting rod is hinged to the end of the sliding sleeve facing the threaded rod.

[0011] In some embodiments, the ball socket surface of the lower housing is provided with a straight groove that mates with the connecting plate, and the ball socket surface of the upper housing is provided with a slot for limiting the position of the connecting plate.

[0012] In some embodiments, two slide rods are fixed inside the upper housing, and the two slide rods slide inside the lower housing. A threaded post is threadedly connected to the middle of the upper housing, and the lower end of the threaded post is rotatably connected inside the lower housing.

[0013] In some embodiments, the base includes a plurality of mounting holes symmetrically formed on the surface of the base and a plurality of grooves formed on the lower surface of the base, for improving the adhesion of the strong 3M adhesive to the base.

[0014] Compared with the prior art, the present invention provides a GNSS vehicle-mounted terminal installation component, which has the following beneficial effects.

[0015] 1. This utility model, by setting a limiting component, before clamping and fixing the ball head, causes the sliding sleeve to drive the limiting plug close to the ball head, so that the spring drives the first plug rod and the second plug rod to be inserted into the plug hole surface, thereby limiting the ball head and preventing the vibration generated when the construction machinery vehicle is working from causing the clamping of the ball head to loosen and the orientation angle of the display terminal to change.

[0016] 2. This utility model provides elasticity to the limiting plug by setting a spring and a guide rod. When the socket does not correspond to the first and second insert rods, the relative position of the limiting plug and the ball head can be finely adjusted by rotating the upper and lower housings or the fixed base, so that the first and second insert rods are inserted into the socket surface.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-6A GNSS vehicle-mounted terminal mounting assembly includes an upper housing 1 and a lower housing 2. A base 3 and a fixing seat 4 are respectively mounted on both ends of the upper housing 1 and the lower housing 2 via a rotating assembly 5. Two sliding rods 7 are fixed inside the upper housing 1 and slide inside the lower housing 2. A threaded post 6 is threadedly connected to the middle of the upper housing 1. The lower end of the threaded post 6 is rotatably connected to the inside of the lower housing 2. A first rotating handle is fixed to the outer end of the threaded post 6. The base 3 includes a plurality of mounting holes 301 symmetrically opened on the surface of the base 3. A plurality of grooves 302 are opened on the lower surface of the base 3. A plurality of fixing holes 401 for fixing the display terminal are opened on the surface of the fixing seat 4.

[0028] The rotating assembly 5 includes a ball head 501 fixed to the surface of the base 3 or the surface of the fixed seat 4, and a ball socket 502 with the upper or lower ends of the upper housing 1 and the lower housing 2. The ball head 501 rotates on the surface of the ball socket 502.

[0029] Understandably, by using strong 3M adhesive to fix the base 3 in the cab, the adhesive effect of the strong 3M adhesive on the base 3 is improved through the mounting holes 301 and grooves 302. Under the action of the fixing holes 401, the display terminal is fixed to the surface of the fixing seat 4 with bolts. The orientation of the display terminal is adjusted by the rolling of the ball head 501 in the ball socket 502, making it easier for the driver to observe. By setting the threaded post 6, the first rotating handle is rotated, thereby driving the upper housing 1 to move closer to the lower housing 2, so that the upper housing 1 and the lower housing 2 are clamped by the ball head 501 through the two ball sockets 502, thereby fixing and limiting the orientation of the display terminal. By setting two sliding rods 7, the stability of the upper housing 1 and the lower housing 2 during relative displacement is improved.

[0030] Specifically, the upper housing 1 and the lower housing 2 are provided with two sets of limiting components 8 that limit the two ball heads 501 respectively. The limiting component 8 includes a sliding sleeve 801 that slides on the inner wall of the lower housing 2 and a guide rod 802 that slides on the inner wall of the sliding sleeve 801. A limiting plug 803 is fixed at one end of the guide rod 802 near the ball head 501. Multiple insertion holes 9 are opened on the surface of the ball head 501. The spacing between the multiple insertion holes 9 is the same. A spring 804 is sleeved on the surface of the guide rod 802 for pushing the limiting plug 803 to be inserted into the surface of the insertion hole 9.

[0031] The limiting plug 803 includes a connecting plate 8031 ​​fixed to the end of the guide rod 802 facing the ball head 501, and a first insert 8032 and a plurality of second inserts 8033 fixed to the end of the connecting plate 8031 ​​facing the ball head 501. The first insert 8032 is located at the center of the connecting plate 8031 ​​and corresponds to the center of the ball head 501. The distance between the plurality of second inserts 8033 and the first insert 8032 is the same as the spacing between the plurality of sockets 9. The diameter of the plurality of second inserts 8033 is smaller than the diameter of the sockets 9.

[0032] Understandably, since the ball head 501 is fixed by the upper housing 1 and the lower housing 2 clamping the ball head 501 through the ball socket 502, the vibration generated during the operation of the construction machinery vehicle can easily cause the clamping of the ball head 501 to loosen, thereby causing the display terminal to loosen. Therefore, a limiting component 8 is set. Before clamping and fixing the ball head 501, the sliding sleeve 801 drives the limiting plug 803 to approach the ball head 501, so that the spring 804 drives the first plug 8032 and the second plug 8033 to abut against the surface of the ball head 501. When the socket 9 does not correspond to the first plug 8032 and the second plug 8033, the limiting plug 803 is fixed by rotating the upper housing 1 and the lower housing 2 or the fixing seat 4. The relative position of the ball head 501 is finely adjusted so that the first insertion rod 8032 and the second insertion rod 8033 are inserted into the surface of the socket 9, thereby limiting the ball head 501 and preventing the vibration generated during the operation of the construction machinery vehicle from causing the clamping of the ball head 501 to loosen and change the orientation angle of the display terminal. When the first insertion rod 8032 corresponds to the socket 9, the orientation of the socket 9 corresponding to the second insertion rod 8033 does not correspond to the axial direction of the second insertion rod 8033. Therefore, by setting the diameter of the second insertion rod 8033 to be smaller than the diameter of the socket 9, the second insertion rod 8033 can be smoothly inserted into the socket 9, avoiding insufficient limiting strength of the ball head 501 by the first insertion rod 8032 alone.

[0033] Specifically, both sets of sliding sleeves 801 are driven to slide by the transmission assembly 805. The transmission assembly 805 includes a threaded rod 8051 threaded to the surface of the upper housing 1 and a slider 8052 threaded to the surface of the threaded rod 8051. The lower end of the threaded rod 8051 is inserted into the inner wall of the lower housing 2, realizing the rotation and sliding of the threaded rod 8051 on the inner wall of the lower housing 2. One end of the slider 8052 slides on the surface of the sliding rod 7, and the other end of the slider 8052 is hinged to a connecting rod 8053. The other end of the connecting rod 8053 is hinged to the end of the sliding sleeve 801 facing the threaded rod 8051. A second rotating handle is fixed to the outer end of the threaded rod 8051.

[0034] It is understandable that the threaded rod 8051 drives the slider 8052 to slide on the surface of the guide rod 802, thereby driving the connecting rod 8053 to adjust its angle, so that the connecting rod 8053 drives the sliding sleeve 801 to slide on the inner wall of the lower housing 2. By inserting the lower end of the threaded rod 8051 into the inner wall of the lower housing 2, the threaded rod 8051 is prevented from affecting the relative displacement between the upper housing 1 and the lower housing 2. At the same time, the lower end of the threaded rod 8051 can be limited, thereby improving the stability of the threaded rod 8051.

[0035] Specifically, the ball socket 502 of the lower housing 2 has a straight groove 10 that mates with the connecting plate 8031, and the ball socket 502 of the upper housing 1 has a slot 11 for limiting the connecting plate 8031.

[0036] Understandably, when the first insertion rod 8032 and the second insertion rod 8033 are both inserted into the insertion hole 9, the connecting plate 8031 ​​is located on the inner wall of the straight groove 10. At the same time, the ball head 501 is clamped by the ball sockets 502 at both ends of the upper housing 1 and the lower housing 2, and the slot 11 is sleeved on the surface of the connecting plate 8031. The connecting plate 8031 ​​is clamped by the slot 11 and the straight groove 10. At the same time, the slot 11 can limit the position of the connecting plate 8031, thereby preventing the connecting plate 8031 ​​from causing the first insertion rod 8032 and the second insertion rod 8033 to disengage from the insertion hole 9 and causing the limiting to fail.

[0037] In this invention, a strong 3M adhesive is used to fix the base 3 in the cab. The mounting holes 301 and grooves 302 enhance the adhesion of the strong 3M adhesive to the base 3. Under the action of the fixing holes 401, bolts are used to fix the display terminal to the surface of the fixing base 4. The orientation of the display terminal is adjusted by the rolling of the ball head 501 within the ball socket 502, facilitating observation by the driver. Then, rotating the second handle causes the threaded rod 8051 to drive the slider 8052 to slide on the surface of the guide rod 802, thereby causing the connecting rod 8053 to drive the sliding sleeve 801 to slide on the inner wall of the lower housing 2. The sliding sleeve 801 then drives the limiting plug 803 closer to the ball head 501, causing the spring 804 to drive the first insertion rod 8032 and the second insertion rod 8033 to abut against the surface of the ball head 501. When the insertion hole 9 does not correspond to the first insertion rod 8032 and the second insertion rod 8033, rotation... The upper housing 1 and the lower housing 2 or the fixed base 4 finely adjust the relative position of the limiting plug 803 and the ball head 501, so that the first plug rod 8032 and the second plug rod 8033 are inserted into the surface of the socket 9, thereby limiting the ball head 501 and preventing the vibration generated during the operation of the construction machinery vehicle from causing the clamping of the ball head 501 to loosen and change the orientation angle of the display terminal. Then, the first rotating handle is rotated, thereby driving the upper housing 1 to move closer to the lower housing 2, so that the upper housing 1 and the lower housing 2 clamp the ball head 501 through the two ball sockets 502. At the same time, the slots 11 and straight grooves 10 on the surface of the upper housing 1 and the lower housing 2 clamp the connecting plate 8031. The slots 11 can limit the position of the connecting plate 8031, thereby preventing the connecting plate 8031 ​​from causing the first plug rod 8032 and the second plug rod 8033 to disengage from the socket 9 and causing the limiting to fail.
