Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and in particular to a fixed vehicle accessory lamp. Background Technology

[0002] Lighting technology is rapidly penetrating the automotive field. Fixed automotive accessory lights, as an important carrier for automotive decoration and auxiliary lighting, are widely used in the corners of the car body and the junction of interior trim, such as door panels, front grilles, and dashboards. They can not only enhance the aesthetics of the car's exterior and interior through lighting decoration and meet the personalized needs of car owners, but also help optimize the lighting environment inside the car.

[0003] Among these types of vehicle-mounted lights, longer lights are prone to loosening after installation due to their length. To ensure installation stability, existing technologies typically use elastic clamps to fix both ends of the lights. This fixing method is simple in structure, easy to disassemble, and can quickly complete the installation and maintenance of the lights, meeting the actual usage needs of vehicle-mounted scenarios.

[0004] However, continuous vibrations are inevitable during vehicle operation. These vibrations cause repeated interactions between the headlight and the elastic clamp, leading to wear at the contact points. Over time, this wear widens the gap between the headlight and the clamp, making the headlight wobble more pronounced. This creates a vicious cycle of "vibration—wear—increased wobble," affecting not only the headlight's aesthetics and stability but also potentially causing abnormal noises or even detachment, posing a safety hazard. Summary of the Invention

[0005] Therefore, it is necessary to provide a fixed vehicle accessory light that addresses the problem of wear and sway caused by vibration, which cannot be solved by the current fixing mechanism of vehicle lights.

[0006] The above objectives are achieved through the following technical solutions: A fixed vehicle-mounted accessory light includes a lamp post and two clamping mechanisms. Each clamping mechanism includes an auxiliary seat, an arc plate, and an adjustment component. The auxiliary seat is mounted on the vehicle body and supports the lamp post, located at the end of the lamp post. The arc plate is oscillating on the auxiliary seat about a preset axis parallel to the lamp post. The preset axis is located inside the arc plate and has a gap between it and the arc plate. The concave surface of the arc plate faces the lamp post, and two elastic plates arranged circumferentially along the arc plate and sliding radially along the arc plate are arranged on the concave surface. The elastic plates are connected to the arc plate through elastic elements. The lamp post is located between the arc plate and the... Between the preset axes of the swinging arc plate, the swinging arc plate causes one of its elastic plates to approach and abut against the lamp post; there are three arc plates, which are arranged along the circumferential direction of the lamp post. Two elastic plates on two arc plates that are adjacent in the circumferential direction of the lamp post are grouped together, and the three groups of elastic plates are evenly arranged along the circumferential direction of the lamp post; each arc plate is provided with a top rod that corresponds to one elastic plate. The top rod is located on the side of the corresponding elastic plate away from the lamp post. When the arc plate swings, each top rod can abut against another elastic plate in the same group as the corresponding elastic plate, causing the other elastic plate to restore its deformation.

[0007] The adjustment assembly is used to control the synchronous reciprocating rotation of the three arc plates in the same direction, so that one of the elastic plates in each group of the same arc plate abuts against the lamp post, and the elastic plate that is not abutting against the lamp post abuts against the corresponding top rod.

[0008] Preferably, the adjustment assembly includes a crankshaft, an eccentric sleeve, and a synchronizing element. The crankshaft is mounted on the auxiliary seat and located on one side of the lamp post end. The crankshaft extends along the length of the lamp post and includes three eccentric segments. The axis of each eccentric segment coincides with the preset axis of the swing of one of the arc plates, and the vertical distance between the axis of any eccentric segment and the axes of the other two eccentric segments is equal. Each eccentric sleeve is fitted onto one eccentric segment and rotatably connected to the corresponding eccentric segment. Each arc plate is rotatably mounted on one eccentric sleeve and coaxial with the outer circle of the corresponding eccentric sleeve. The line connecting the two elastic plates on the arc plate is perpendicular to the line connecting the center of the inner hole and the center of the outer circle of the eccentric sleeve, and the elastic plates are located on both sides of the center of the inner hole and the center of the outer circle of the eccentric sleeve. The synchronizing element is used to make the three eccentric sleeves rotate synchronously and in the same direction.

[0009] Preferably, the synchronizing element includes a synchronizing rod. Each eccentric sleeve has multiple through holes that penetrate it along its axial direction. The through holes on the three eccentric sleeves correspond one-to-one and are connected in the radial direction of the crankshaft. The synchronizing rod passes through the interconnected through holes and is slidably connected to the eccentric sleeve along the radial direction of the corresponding eccentric sleeve.

[0010] Preferably, when the lamp post is not in contact with the elastic plate, the outer circles of the three eccentric sleeves are coaxial and the axis of the outer circles of the three sleeves coincides with the center of the axis of the three eccentric segments.

[0011] Preferably, the crankshaft has three scale lines arranged circumferentially along the crankshaft on the eccentric section away from the lamp post. One scale line is the center line, and the other two scale lines are symmetrical about the center line. The eccentric sleeve corresponding to the eccentric section with scale lines is equipped with a pointer. When the pointer points to the center line, the outer circles of the three eccentric sleeves are coaxial. When the pointer points to the other two scale lines, the three sets of elastic plates clamp the lamp post.

[0012] Preferably, each eccentric sleeve is fitted with a connecting cylinder on its circumferential surface. The connecting cylinder is rotatably connected to the eccentric sleeve. The ends of multiple connecting cylinders are flush with the lamp post and extend beyond the crankshaft. Adjacent connecting cylinders have a gap in the radial direction of the lamp post. Each arc plate is rotatably mounted on a connecting cylinder and is coaxial with the corresponding connecting cylinder.

[0013] Preferably, the elastic plate is arc-shaped, and its curvature matches the curvature of the lamp post's circumference. The elastic element connected to the elastic plate is located between the elastic plate and the arc plate and extends and retracts along the radial direction of the arc plate.

[0014] Preferably, each auxiliary seat is provided with a support plate, which is located at the end of the arc plate near the lamp post. The lamp post is placed on the support plate. One of the arc plates is provided with a stop block, which is located on the side of the support plate away from the lamp post and can abut against the support plate when the arc plate rotates relative to the eccentric sleeve.

[0015] Preferably, the arc plate with the stop block is slidably connected to two other arc plates in the circumferential direction of the lamp post and can be engaged with the other two arc plates. After the other two arc plates are engaged with the arc plate with the stop block, they can also abut against each other and engage in the circumferential direction of the lamp post. The arc plates after being engaged with each other are cylindrical, and the three arc plates are relatively fixed in the circumferential direction and can rotate synchronously.

[0016] Preferably, the fixed vehicle accessory light also includes a mounting bracket, which is disposed on the vehicle body and located in the middle of the light pole, and the light pole and the mounting bracket are engaged in the circumferential direction of the light pole.

[0017] The beneficial effects of this invention are: the three arc plates are arranged in an orderly manner along the circumferential direction of the lamp post, and through their cooperation with the lamp post, one side of the arc plate can move closer to or further away from the lamp post during the reciprocating swing of the arc plate. At the same time, the elastic plates on the arc plates are evenly arranged along the circumferential direction of the lamp post to form a symmetrical three-point clamping mechanism, which can apply a uniform radial compressive force to the lamp post, effectively preventing the lamp post from shifting or loosening under force, resisting the shaking caused by the bumpy environment of the vehicle, and ensuring the reliability of the lamp post fixation.

[0018] The elastic plate on the arc plate adopts an elastic abutment structure, which always maintains a stable compressive force on the lamp post, further improving the fixation firmness of the lamp post in the vehicle environment.

[0019] The two elastic plates on the same arc plate can work alternately as the arc plate swings, avoiding fatigue failure caused by long-term pressure on a single elastic plate, effectively extending the service life of the elastic plate and improving the overall durability of the clamping mechanism.

[0020] Each arc plate is equipped with a top rod corresponding to the elastic plate. During the swinging process of the arc plate, the top rod can abut against the elastic plate in the same group that has not yet abutted the lamp post, forming support for the elastic plate that has exited the working state, allowing it to return to its initial state by combining its own elasticity. This ensures that the clamping effect is consistent when the elastic plates work repeatedly. The overall structure is simple, the transmission is reliable, and the adjustment is synchronous, making it suitable for the long-term stable fixing requirements of vehicle accessory lights.

[0026] like Figures 1 to 8As shown, this embodiment of the invention provides a fixed vehicle accessory light, including a lamp post 100 and two clamping mechanisms. Each clamping mechanism includes an auxiliary seat 101, an arc plate 102, and an adjustment assembly. The auxiliary seat 101 is disposed on the vehicle body and is used to support the lamp post 100. The auxiliary seat 101 is located at the end of the lamp post 100. The arc plate 102 is reciprocatingly mounted on the auxiliary seat 101 about a preset axis parallel to the lamp post 100. The preset axis is located inside the arc plate 102 and has a gap between it and the arc plate 102. The concave surface of the arc plate 102 faces the lamp post 100, and two elastic plates 103 are disposed on the concave surface, arranged along the circumferential direction of the arc plate 102 and sliding along the radial direction of the arc plate 102. The elastic plates 103 are connected to the arc plate 102 through elastic elements 104. The lamp post 100 is located on the arc plate 102. Between the preset axis of the swing of the arc plate 102 and the arc plate 102, the arc plate 102 swings so that one of its elastic plates 103 approaches the lamp post 100 and abuts against the lamp post 100; there are three arc plates 102, and the three arc plates 102 are arranged along the circumferential direction of the lamp post 100. Two adjacent elastic plates 103 on two arc plates 102 in the circumferential direction of the lamp post 100 are grouped together, and the three groups of elastic plates 103 are evenly arranged along the circumferential direction of the lamp post 100; each arc plate 102 is provided with a top rod 105 corresponding to one elastic plate 103. The top rod 105 is located on the side of the corresponding elastic plate 103 away from the lamp post 100. When the arc plate 102 swings, each top rod 105 can abut against another elastic plate 103 in the same group as the corresponding elastic plate 103, causing the other elastic plate 103 to recover its deformation.

[0027] The adjustment component is used to control the three arc plates 102 to reciprocate synchronously in the same direction, so that one of the elastic plates 103 in each group of the same arc plate 102 abuts against the lamp post 100, and the elastic plate 103 that does not abut against the lamp post 100 abuts against the corresponding top rod 105.

[0028] Three arc plates 102 are arranged in an orderly manner along the circumference of the lamp post 100. Through their cooperation with the lamp post 100, one side of the arc plate 102 can move closer to or further away from the lamp post 100 during the reciprocating swing of the arc plate 102. At the same time, the elastic plates 103 on the arc plate 102 are evenly arranged along the circumference of the lamp post 100 to form a symmetrical three-point clamping mechanism. This mechanism can apply a uniform radial compressive force to the lamp post 100, effectively preventing the lamp post 100 from shifting or loosening under force, resisting the shaking caused by the bumpy environment of the vehicle, and ensuring the reliability of the lamp post 100's fixation.

[0029] The elastic plate 103 on the arc plate 102 adopts an elastic abutment structure, which always maintains a stable compressive force on the lamp post 100, further improving the fixation firmness of the lamp post 100 in the vehicle environment.

[0030] The two elastic plates 103 on the same arc plate 102 can work alternately as the arc plate 102 swings, avoiding fatigue failure caused by long-term pressure on a single elastic plate 103, effectively extending the service life of the elastic plate 103 and improving the overall durability of the clamping mechanism.

[0031] Each arc plate 102 is provided with a top rod 105 corresponding to the elastic plate 103. During the swinging process of the arc plate 102, the top rod 105 can abut against the elastic plate 103 in the same group that has not abutted against the lamp post 100, and provide support for the elastic plate 103 that has exited the working state, so that it can return to the initial state by combining its own elasticity. This ensures that the clamping effect of the elastic plate 103 is consistent when it repeatedly works alternately. The overall structure is simple, the transmission is reliable, and the adjustment is synchronous, which is suitable for the long-term stable fixing requirements of vehicle accessory lights.

[0032] In this embodiment, the adjustment assembly includes a crankshaft 110, an eccentric sleeve 111, and a synchronizing element. The crankshaft 110 is mounted on the auxiliary seat 101 and located on one side of the end of the lamp post 100. The crankshaft 110 extends along the length of the lamp post 100 and includes three eccentric segments. The axis of each eccentric segment coincides with the preset axis of the swing of one of the arc plates 102, and the perpendicular distance between the axis of any eccentric segment and the axes of the other two eccentric segments is equal. The line connecting the three eccentric segments forms an equilateral triangle, and the three sides of the equilateral triangle... The apex is located on the axis of the three eccentric segments. Each eccentric sleeve 111 is fitted onto one eccentric segment and rotatably connected to the corresponding eccentric segment. Each arc plate 102 is rotatably mounted on one eccentric sleeve 111 and is coaxial with the outer circle of the corresponding eccentric sleeve 111. The line connecting the two elastic plates 103 on the arc plate 102 is perpendicular to the line connecting the center of the inner hole and the center of the outer circle of the eccentric sleeve 111. The elastic plates 103 are located on both sides of the center of the inner hole and the center of the outer circle of the eccentric sleeve 111. The synchronizing element is used to make the three eccentric sleeves 111 rotate synchronously and in the same direction.

[0033] Specifically, the end of the crankshaft 110 furthest from the lamp post 100 is connected to the auxiliary seat 101 by bolts, and the end of the crankshaft 110 near the auxiliary seat 101 is provided with a groove 113. The auxiliary seat 101 is provided with a protrusion 114, which is inserted into the groove 113 to prevent the crankshaft 110 from rotating. The outer diameters of the three eccentric sleeves 111 gradually decrease along the direction close to the lamp post 100, and the outermost arc plate 102 of the lamp post 100 is set on the eccentric sleeve 111 with the largest outer diameter.

[0034] When the eccentric sleeve 111 is rotated, the outer circle of the eccentric sleeve 111 will rotate around the preset axis (i.e., the axis of the corresponding eccentric segment), and at the same time drive the arc plate 102 on it to make cycloidal motion, so that the two elastic plates 103 on the arc plate 102 will move closer to and further away from the lamp post 100 respectively, thus completing the clamping and releasing of the lamp post 100; through the synchronizing element, the three eccentric sleeves 111 rotate synchronously in the same direction, so that the three sets of elastic plates 103 apply force evenly when clamping the lamp post 100, ensuring the stability of the lamp post 100.

[0035] In this embodiment, the synchronizing element includes a synchronizing rod 112. Each eccentric sleeve 111 has multiple through holes 115 extending through itself along its axial direction. The through holes 115 on the three eccentric sleeves 111 correspond one-to-one and are connected in the radial direction of the crankshaft 110. The synchronizing rod 112 passes through the interconnected through holes 115 and is slidably connected to the eccentric sleeve 111 along the radial direction of the corresponding eccentric sleeve 111.

[0036] Specifically, by cooperating with the synchronizing rod 112 and the through hole 115, the eccentric sleeve 111 with the largest outer diameter is rotated. The eccentric sleeve 111 can drive the other two eccentric sleeves 111 to rotate synchronously at a certain angle through the synchronizing rod 112. This allows the three sets of elastic plates 103 to clamp the lamp post 100 at the same time, improving the stability of the lamp post 100 and reducing the number of operation steps.

[0037] In this embodiment, when the lamp post 100 is not in contact with the elastic plate 103, the outer circles of the three eccentric sleeves 111 are coaxial and the axis of the outer circles of the three sleeves coincides with the center of the axis of the three eccentric segments (that is, the center of the equilateral triangle formed by the lines connecting the axes of the three eccentric segments).

[0038] Specifically, the initial position of the three eccentric sleeves 111 when they are coaxial is the initial position of the eccentric sleeves 111. When the eccentric sleeves 111 rotate around their corresponding eccentric segments in the initial position, one of the elastic plates 103 on the upper arc plate 102 will move closer to the lamp post 100, and the other elastic plate 103 will move away from the lamp post 100. The three elastic plates 103 that move closer to the lamp post 100 clamp the lamp post 100. At the same time, when the eccentric sleeves 111 are in the initial position, the relative distances between the three sets of elastic plates 103 and the lamp post 100 are relatively consistent, which can improve the stability of the lamp post 100 during the clamping process.

[0039] In this embodiment, the crankshaft 110 has three scale lines 116 arranged along the circumferential direction of the eccentric segment away from the lamp post 100. One scale line 116 is the center line, and the other two scale lines 116 are symmetrical about the center line. The eccentric sleeve 111 corresponding to the eccentric segment with scale lines 116 is provided with a pointer. When the pointer points to the center line, the outer circles of the three eccentric sleeves 111 are coaxial. When the pointer points to the other two scale lines 116, the three sets of elastic plates 103 clamp the lamp post 100.

[0040] Specifically, the outer diameter of the eccentric sleeve 111 with the pointer is the largest, and its circumference is provided with anti-slip texture for easy rotation. By rotating the eccentric sleeve 111 through the anti-slip texture, the pointer on it points to different scale lines 116, so that the elastic plate 103 is in different positions, making it easy to determine the state of the elastic plate 103 at this time.

[0041] In this embodiment, a connecting cylinder 117 is fitted on the circumferential surface of each eccentric sleeve 111. The connecting cylinder 117 is rotatably connected to the eccentric sleeve 111. The ends of the multiple connecting cylinders 117 close to the lamp post 100 are flush with each other and extend beyond the crankshaft 110. Two adjacent connecting cylinders 117 have a gap in the radial direction of the lamp post 100. Each arc plate 102 is rotatably mounted on a connecting cylinder 117 and is coaxial with the corresponding connecting cylinder 117.

[0042] Specifically, a connecting cylinder 117 is provided to reduce the axial length of the arc plate 102, thereby reducing the amount of sway and cantilever bending moment of the arc plate 102 during rotation, improving motion stability and structural rigidity, and reducing lateral load and wear on the guide components.

[0043] In this embodiment, the elastic plate 103 is arc-shaped, and its curvature is adapted to the curvature of the lamp post 100. The elastic element 104 connected to the elastic plate 103 is located between the elastic plate 103 and the arc plate 102 and extends and retracts in the radial direction of the arc plate 102.

[0044] Specifically, the curvature of the elastic plate 103 is adapted to the curvature of the lamp post 100, which can increase the contact area between the elastic plate 103 and the lamp post 100, improve the friction between the elastic plate 103 and the lamp post 100, and improve the stability of the lamp post 100. The elastic element 104 is used to provide the elastic plate 103 with a force that moves towards the lamp post 100.

[0045] In this embodiment, each auxiliary seat 101 is provided with a support plate 118. The support plate 118 is located at the end of the arc plate 102 near the lamp post 100. The lamp post 100 is placed on the support plate 118. One of the arc plates 102 is provided with a stop block 119. The stop block 119 is located on the side of the support plate 118 away from the lamp post 100 and can abut against the support plate 118 when the arc plate 102 rotates relative to the eccentric sleeve 111.

[0046] Specifically, when the eccentric sleeve 111 is in its initial position, the line connecting the axes of the inner hole and the outer circle of the eccentric sleeve 111 is parallel to the perpendicular bisector of the corresponding arc plate 102, so as to prevent the arc plate 102 from rotating arbitrarily when the eccentric sleeve 111 is in its initial position, which would prevent the elastic plate 103 on the arc plate 102 from moving closer to the lamp post 100 when the eccentric sleeve 111 rotates.

[0047] In this embodiment, the arc plate 102 with the stop block 119 is slidably connected to the other two arc plates 102 in the circumferential direction of the lamp post 100 and can be engaged with the other two arc plates 102. After the other two arc plates 102 are engaged with the arc plate 102 with the stop block 119, they can also abut against each other and be engaged in the circumferential direction of the lamp post 100. The arc plates 102 after being engaged with each other are cylindrical. The three arc plates 102 are relatively fixed in the circumferential direction and can rotate synchronously.

[0048] Specifically, one of the two arc plates 102 slidably connected to the arc plate 102 with the stop block 119 has two clamping plates 120 arranged along the axial direction of the lamp post 100 with a gap. The side of the two clamping plates 120 that is far apart from each other has a protrusion. The clamping plates 120 are elastic in the axial direction of the lamp post 100, and the protrusion has a guide slope. The other arc plate 102 has a slot 121. After the two arc plates 102 abut, the clamping plates 120 are inserted into the slot 121 through their respective guide slopes. The protrusion passes through the slot 121 and abuts against the arc plate 102 where the slot 121 is located under the elastic action of the clamping plate 120, thereby realizing the clamping of the two arc plates 102. At this time, the three arc plates 102 can rotate synchronously. At the same time, the clamping plates 120 can slide in the slot 121 along the radial direction of the lamp post 100 to avoid interference between the arc plates 102 when they swing.

[0049] After the three arc plates 102 rotate and engage, the elastic plates 103 of the same group will overlap in the axial direction of the lamp post 100. The push rods 105 on the arc plates 102 corresponding to the elastic plates 103 will move to the side of the corresponding elastic plate 103 away from the lamp post 100. When the elastic plate 103 moves away from the lamp post 100, it will approach the corresponding push rod 105. The push rod 105 will apply a reverse pushing force to the elastic plate 103, thereby causing the elastic element 104 connected to the elastic plate 103 to stretch and restore its elasticity.

[0050] In this embodiment, the fixed vehicle accessory light also includes a mounting base 122, which is disposed on the vehicle body and located in the middle of the lamp post 100. The lamp post 100 and the mounting base 122 are engaged in the circumferential direction of the lamp post 100.

[0051] Specifically, the mounting base 122 and the lamp post 100 are connected by bolts, with one end of the bolt passing through the mounting base 122 and screwed onto the lamp post 100; the mounting base 122 is installed on the vehicle body by screws, and after the mounting base 122 is screwed onto the lamp post 100, the lamp post 100 will not rotate circumferentially, and its illumination direction is stable.

[0052] The working principle of the fixed vehicle accessory light provided in the above embodiment is as follows: First, install the two auxiliary seats 101 on the vehicle body and rotate the eccentric sleeve 111 so that the pointer on the eccentric sleeve 111 points to the center line. Then, separate the cylindrical and interlocking arc plates 102 on the auxiliary seats 101 to open a notch. Next, install the lamp post 100 on the fixing seat 122. Then, install the fixing seat 122 on the vehicle body so that the lamp post 100 is placed on the support plate 118. The end of the lamp post 100 is located inside the corresponding arc plate 102 through the notch. Then rotate the two interlocking arc plates 102 so that the locking plate 120 on one arc plate 102 approaches the locking groove 121 on the other arc plate 102. The locking plate 120 is inserted into the locking groove 121 through the guide slope and elastically bends towards the other locking plate 120. When the two arc plates 102 abut against each other, the protrusion on the locking plate 120 passes over the locking groove 121 and the locking plate 120 elastically returns to its original position. The locking plate 120 is interlocked with the locking groove 121 in the circumferential direction of the lamp post 100 through the protrusion.

[0053] Then, by rotating one of the eccentric sleeves 111 through the anti-slip texture, the rotation of the eccentric sleeve 111 drives the connecting cylinder 117 on it to rotate around the axis of the corresponding eccentric segment. The connecting cylinder 117 drives the corresponding arc plate 102 to rotate synchronously. One elastic plate 103 on the arc plate 102 moves closer to the lamp post 100 and abuts against the lamp post 100, while the other elastic plate 103 moves away from the lamp post 100. The elastic plate 103 that abuts against the lamp post 100 compresses the corresponding elastic element 104. At the same time, one side of the arc plate 102 moves closer to the lamp post 100, causing one of its push rods 105 to move closer to and abut against another elastic plate 103 in the same group. The push rod 105 pushes the elastic plate 103 to tend to move closer to the lamp post 100 and stretches the elastic element 104 corresponding to the elastic plate 103.

[0054] The rotating eccentric sleeve 111 drives the other two eccentric sleeves 111 to rotate synchronously around their respective preset axes via the synchronizing rod 112. The three arc plates 102, on the same side of the lamp post 100 in the circumferential direction, cause the elastic plates 103 on them to abut against the lamp post 100, thus clamping the lamp post 100. The eccentric sleeve 111 is continuously rotated until the pointer points to another scale line 116. At this time, the elastic elements 104 corresponding to the elastic plates 103 that abut against the lamp post 100 are all compressed, and the lamp post 100 is firmly clamped.

[0055] After a period of use, the eccentric sleeve 111 can be rotated in the reverse direction, causing the pointer to approach the center line and then cross it to point to another scale line 116. The arc plates 102 rotate in the reverse direction around their respective preset axes. The elastic plate 103 that was originally in contact with the lamp post 100 moves away from the lamp post 100, while the elastic plate 103 that was not originally in contact moves closer to the lamp post 100 and comes into contact with it. The two elastic plates 103 in the same group alternately come into contact with the lamp post 100, and the elastic plate 103 that has exited the working state comes into contact with the corresponding push rod 105 on the adjacent arc plate 102, so that the elastic element 104 connected to the elastic plate 103 is stretched and reset, avoiding fatigue failure of the elastic element 104 due to long-term pressure, and ensuring a stable and reliable fixing effect on the lamp post 100 during long-term use.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
