Description

Technical Field

[0001] This utility model relates to the field of display screen bracket technology, and in particular to a high-temperature resistant ball head bracket. Background Technology

[0002] Conventional vehicle side mirrors have limitations in size and adjustment angle, creating significant blind spots for the driver and severely impacting driving safety, especially for heavy-duty trucks. Currently, many trucks are equipped with electronic side mirrors to reduce blind spots and improve driving safety. After installing electronic side mirrors, a corresponding display screen is needed inside the vehicle for the driver to view. Currently, the display screen bracket is typically a ball joint bracket for angle adjustment; however, in high temperatures, the ball joint can soften, causing the structure connecting to the display screen to loosen and resulting in the display screen drooping.

[0029] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0030] According to some embodiments of this utility model, refer to Figures 1 to 3 The high-temperature resistant ball head bracket includes a fixed component 100 and a rotating component 200. The fixing assembly 100 includes a fixing base 110, a first housing 121, a second housing 122, a spring piece 160, a first bolt 170, and a tightening nut 180. The first housing 121 is located above the second housing 122. The rear end of the first housing 121 is fixedly connected to the fixing base 110. The first housing 121 and the second housing 122 are detachably connected. The first housing 121 and the second housing 122 can cover each other to form a receiving area 130. The receiving area 130 is located at the front end of the first housing 121 and the second housing 122. The first bolt 170 passes through the second housing 122, the first housing 121, and the spring piece 160 from bottom to top. The tightening nut 180 is located above the spring piece 160. The tightening nut 180 is threadedly connected to the upper end of the first bolt 170. The spring piece 160 is located between the first housing 121 and the tightening nut 180. The tightening nut 180 and the first bolt 170 cooperate to fix the first housing 121 and the second housing 122 relatively. Tightening the nut 180 and the first housing 121 engages to compress the spring 160, ensuring that the spring 160 is always in a compressed state. The spring 160 exerts a force on the first housing 121 toward the second housing 122, causing the receiving area 130 to tend to contract. The rotating assembly 200 includes a rotating ball 210 and a connecting plate 220. The rotating ball 210 is located within the receiving area 130 and is fixedly connected to the connecting plate 220. The rotating ball 210 is capable of rotating within the receiving area 130. The connecting plate 220 is used for connection with the display screen.

[0031] Understandably, during normal operation, the mounting base 110 is installed on the vehicle, the connecting plate 220 is connected to the display screen, and the first housing 121 and the second housing 122 work together to clamp the rotating ball 210, thus fixing the connecting plate 220 and the mounting base 110 relatively. When it is necessary to adjust the angle between the connecting plate 220 and the display screen, the clamping force of the first housing 121 and the second housing 122 on the rotating ball 210 is overcome manually, allowing the rotating ball 210 to rotate within the receiving area 130, thereby adjusting the angle of the connecting plate 220.

[0032] After the rotating ball 210 softens due to high temperature, under the action of the spring piece 160, the first housing 121 continues to move toward the second housing 122, causing the receiving area 130 to contract. This allows the first housing 121 and the second housing 122 to stably press the rotating ball 210, ensuring that the rotating ball 210 is subjected to a sufficiently large clamping force and preventing loosening between the fixed seat 110 and the connecting plate 220.

[0033] According to some embodiments of this utility model, refer to Figures 1 to 3 The fixing assembly 100 also includes an anti-slip pad 190. The first housing 121 is located above the second housing 122. The first bolt 170 passes through the anti-slip pad 190. The lower end face of the anti-slip pad 190 is attached to the first housing 121, and the upper end face of the anti-slip pad 190 is attached to the spring piece 160. The anti-slip pad 190 can prevent the spring piece 160 from sliding, ensuring that the tightening nut 180 can be stably connected with the first bolt 170.

[0034] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The front end of the first housing 121 is provided with a first groove 141, and the front end of the second housing 122 is provided with a second groove 142. When the first housing 121 and the second housing 122 are closed, the first groove 141 and the second groove 142 cooperate to form a receiving area 130 with the opening facing forward, and the rotating ball 210 is located in the receiving area 130.

[0036] Preferred, refer to Figures 1 to 3 The connecting plate 220 is provided with a plurality of second through holes 221, and the rotating assembly 200 also includes a plurality of second bolts 222. The plurality of second through holes 221 correspond one-to-one with the plurality of second bolts 222. The second bolts 222 and the second through holes 221 can cooperate to fix the connecting plate 220 and the display screen relative to each other.

[0037] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The rotating assembly 200 also includes a cylinder 230, the rear end of which is inserted into and fixedly connected to the rotating ball 210, and the cylinder 230 is fixedly connected to the rear end face of the connecting plate 220.
