Description

Technical Field

[0001] This utility model relates to the field of automotive roof positioning technology, and more specifically, to a multifunctional roof positioning device. Background Technology

[0002] The car roof is made of a composite of a base material and a fabric. Generally, after the injection-molded semi-finished base material is processed, a layer of decorative fabric is attached to its lower surface. At both ends of the roof base material and at the sunroof opening, the edges need to be wrapped. That is, the decorative fabric attached to the inner surface of the sunroof frame of the interior roof semi-finished product needs to be flipped from the inner surface of the sunroof frame to the outer surface of the sunroof opening and bonded to the outer surface of the sunroof frame.

[0003] After the automotive headliner is finished, it typically requires multiple data checks, necessitating stable positioning for these checks. Currently, there are various methods for headliner positioning, one of which involves pre-installed plastic pins. This involves a positioning device with corresponding positioning holes, where the headliner is positioned by inserting multiple plastic pins into these holes. This method requires pre-installing plastic pins into the headliner's connector; the assembly of the connector and the plastic pins is called a connector assembly. However, this positioning structure is too limited in function, unable to detect the position of the connector holes for inserting the plastic pins. Currently, detecting the position of these holes requires additional tooling, increasing testing costs. Therefore, developing a multi-functional positioning device that can not only position the headliner but also detect the position of the connector holes is essential. Summary of the Invention

[0004] The problem solved by this utility model is to overcome at least one defect in the prior art and provide a multifunctional ceiling positioning device that can not only realize the insertion and positioning of the ceiling, but also be used for the detection of the insertion hole position of the insertion seat on the ceiling. One structure with two functions reduces the detection cost.

[0005] To address the aforementioned problems, this utility model provides a multifunctional roof positioning device, comprising a base plate on which multiple positioning components are respectively provided, each corresponding to a plurality of plug-in components on a car roof. Each positioning component includes a positioning base and two positioning blocks. The two positioning blocks are connected to the upper end of the positioning base and can move closer to each other and further away from each other. The outer wall of the opposite side of the two positioning blocks is provided with an inner groove. When the two positioning blocks move closer to each other to a first position, the two inner grooves form a positioning hole for the plastic pins of the plug-in components to be inserted and mated. The lower end of the positioning base is provided with a guide channel for a scribing pin to pass through. When the two positioning blocks move further away from each other to a second position, the scribing pin can pass through the guide channel and the gap between the two positioning blocks from bottom to top to scribble on the plug-in seat of the plug-in components to determine whether the plug-in hole position of the plug-in seat has shifted.

[0006] Compared with the prior art, the advantages of this multifunctional ceiling positioning device are: This utility model discloses a multi-functional roof positioning device, which is a special positioning tool mainly used for the detection and positioning of automotive roofs. When the roof needs to be positioned and fixed, plastic pins are inserted into the plug-in base on the roof, and the two positioning blocks in the positioning device are adjusted to the first position. At this time, the roof can be inserted and positioned by the plastic pins and the positioning holes. When it is necessary to detect the position of the plug-in hole of the plug-in base on the roof, the roof needs to be placed on the positioning device with the plastic pins not installed, and the two positioning blocks are adjusted to the second position. Then, the scribing pin passes through the guide channel and the gap between the two positioning blocks from bottom to top and abuts against the plug-in base of the plug-in assembly. Then, the scribing pin is rotated, and the sharp part on the top of the scribing pin scribing line is used to scribing on the lower end face of the plug-in base. The corresponding scribing line is used to determine whether the position of the plug-in hole of the plug-in base is offset. That is, when the two positioning blocks are in the second position, the positioning device can be used to detect whether the position of the plug hole on the plug socket is offset, that is, to detect the position accuracy of the plug hole. If the position of the plug hole is offset too much, the plastic plug and the positioning plug hole cannot be accurately plugged in after the plastic plug is installed.

[0007] Furthermore, it also includes a drive shaft. A positioning partition is provided in the middle of the upper end of the positioning base. Movable plates are provided on the left and right sides of the positioning partition. Threaded through holes are provided on both movable plates, and the threads of the two threaded through holes are in opposite directions. A connecting hole coaxial with the threaded through hole is provided on the positioning partition. One end of the drive shaft is rotatably inserted into the threaded through hole and the connecting hole. Threaded segments that match the two threaded through holes are spaced apart on the outer wall of the drive shaft. A limiting member is provided on the positioning partition to restrict the axial movement of the drive shaft. By rotating the drive shaft in both directions, the two movable plates can be brought closer together or moved away from each other. The two positioning blocks are respectively connected to the two movable plates.

[0008] As an improvement, the positioning partition is also provided with a guide shaft extending in the left-right direction, and both movable plates are provided with guide holes for sliding cooperation with the two ends of the guide shaft respectively.

[0009] Preferably, there are two guide shafts, and the two guide shafts are symmetrically arranged on the upper and lower sides of the drive shaft.

[0010] In a further improvement, the front wall of the positioning partition is connected to two first positioning screws for respectively abutting against the outer walls of the two guide shafts.

[0011] In a further improvement, an annular positioning groove is provided on the outer wall of the drive shaft between the two threaded segments, and the limiting member is a second positioning screw connected to the front wall of the positioning partition, with the inner end of the second positioning screw fitting into the positioning groove.

[0012] In a further improvement, the other end of the drive shaft is equipped with a manual adjustment knob.

[0013] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0016] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0017] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] See appendix Figures 1-6 This utility model provides a multifunctional roof positioning device, which includes a base plate 1. The base plate 1 is provided with a plurality of positioning components that correspond one-to-one with a plurality of plug-in components on a car roof. Each positioning component has the same structure, including a positioning base 2 and two positioning blocks 3. The two positioning blocks 3 are connected to the upper end of the positioning base 2, and the two positioning blocks 3 can move closer to each other and further away from each other. In addition, the outer wall of the opposite side of the two positioning blocks 3 is provided with an inner groove. When the two positioning blocks 3 move closer to each other to the first position, the two inner grooves form a positioning hole 5 for the plastic pins 4 of the plug-in components to be inserted and fitted. That is, when the two positioning blocks 3 are in the first position, the positioning device is used to realize the connection and positioning of the roof. Specifically, the connection and positioning are realized by the cooperation of the plurality of plug-in components on the roof with the plurality of positioning holes 5.

[0020] Furthermore, in the above structure, a vertically extending guide channel 6 is provided at the lower end of the positioning base 2. When the two positioning blocks 3 move away from each other to the second position, the scribing pin can pass through the guide channel 6 and the gap between the two positioning blocks 3 from bottom to top, and then abut against the plug-in seat 7 of the plug-in assembly. Then, the scribing pin is rotated, and the sharp part 18 on the top of the scribing pin scribing pin scribing lines on the lower end surface of the plug-in seat 7. The corresponding scribing lines are used to determine whether the position of the plug-in hole 19 of the plug-in seat 7 is offset. That is, when the two positioning blocks 3 are in the second position, the positioning device can be used to detect whether the position of the plug-in hole 19 on the plug-in seat 7 is offset, that is, to detect the positional accuracy of the plug-in hole 19. If the positional offset of the plug-in hole 19 is too large, the plastic plug 4 cannot be accurately plugged into the positioning plug-in hole 5 after being fitted. In this structure, the scribing pin can be fixed to the base plate 1 by a pull rope to prevent loss. In addition, in this embodiment, the marking pin includes a cylindrical pin 17. A sharp part 18 is provided on the top surface of the cylindrical pin 17 near the outer edge. When the inspector holds the cylindrical pin 17 and rotates it one revolution, the sharp part 18 can walk a circular trajectory on the plug seat 7. If the position of the plug hole 19 is completely consistent with the set fixed position, then the circular trajectory is almost completely coincident with the position of the plug hole 19, and the marking is almost invisible on the outer wall of the plug seat 7. If the position of the plug hole 19 is deviated, a partial marking will be formed on the outer wall of the plug seat 7. The degree of deviation of the marking position from the position of the plug hole 19 is observed to determine whether the processing position of the plug hole 19 meets the requirements.

[0021] For more details, please see the appendix. Figure 2 , 3 In addition to the positioning device structure of embodiment 5, the positioning device structure also includes a drive shaft 8. A positioning partition 9 is provided in the middle of the upper end of the positioning base 2, and the partition extends along the front-back direction of the positioning base 2. Movable plates 10 are provided on the left and right sides of the positioning partition 9, and threaded through holes are provided on both movable plates 10. The threads of the two threaded through holes are opposite in direction. A connecting hole coaxial with the two threaded through holes is provided on the positioning partition 9, that is, the two threaded through holes and the connecting through hole are concentrically arranged. One end of the drive shaft 8 is rotatably inserted into the threaded through holes and the connecting hole. Threaded segments 11 for matching the two threaded through holes are provided at intervals on the outer wall of the drive shaft 8. A limiting member for restricting the axial movement of the drive shaft 8 is provided on the positioning partition 9. By rotating the drive shaft 8 in both directions, the two interactive plates can move closer or further apart under the driving action of the two threaded segments 11. The two positioning blocks 3 are respectively connected to the two movable plates 10, thereby realizing the switching of the two positioning blocks 3 between the first position and the second position. That is, the positioning device can be used as a ceiling connection to achieve positioning function, and it can also be used as a detection function to detect the position of the insertion hole 19 of the insertion seat 7 on the ceiling. One structure with two functions, diversified functions, and reduced ceiling inspection tool cost.

[0022] In the above structure, the two positioning blocks 3 are detachably connected to the two movable plates 10. When the shape and specifications of the plastic pins 4 on the ceiling change, the positioning blocks 3 with the corresponding positioning holes 5 can be replaced, which is very convenient.

[0023] For others, see Appendix Figure 3 To better ensure the stability of the two movable plates 10 during relative movement, a guide shaft 12 extending in the left-right direction is also provided on the positioning partition 9. Specifically, both ends of the guide shaft 12 protrude from both sides of the positioning partition 9, and each of the two movable plates 10 has guide holes for sliding engagement with the two ends of the guide shaft 12. That is, when the two movable plates 10 move relative to each other, the position can be limited by the cooperation between the guide holes and the guide shaft 12, ensuring that the movement will not be skewed. In this embodiment, preferably, there are two guide shafts 12, and the two guide shafts 12 are symmetrically arranged on the upper and lower sides of the drive shaft 8.

[0024] In this embodiment, two first positioning screws 13 are connected to the front wall of the positioning partition 9 to abut against the outer walls of the two guide shafts 12 respectively, so as to ensure the stability of the connection structure between the two guide shafts 12 and the positioning partition 9.

[0025] On the other hand, see Appendix Figure 2 and 5 An annular positioning groove 14 is provided on the outer wall of the drive shaft 8 between two threaded sections 11. The limiting component is a second positioning screw 15 connected to the front wall of the positioning partition 9. When the drive shaft 8 is fitted into the two threaded through holes and the connecting hole, the second positioning screw 15 is screwed in along the front wall of the positioning partition until its inner end fits into the positioning groove 14. Here, the inner end of the second positioning screw 15 does not contact the bottom wall of the positioning groove 14, or it slides in contact, to ensure that the drive shaft 8 can rotate normally, but will not move axially. In this way, it can be ensured that when the drive shaft 8 is rotated, the two interactive plates are driven to move relative to each other under the action of the two threaded sections 11.

[0026] In this embodiment, a manual adjustment knob 16 is provided at the other end of the drive shaft 8 to facilitate rotation. More specifically, anti-slip textures can be provided on the outer wall of the manual adjustment knob 16, or an anti-slip rubber sleeve can be fitted over the manual adjustment knob.

[0027] In this embodiment of the invention, unless otherwise explicitly specified and limited, the "upper end" and "lower end" of the first feature and the second feature can refer to direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Furthermore, the "lower end" and "lower side" of the first feature and the second feature can refer to the first feature being directly below or diagonally below the second feature, or simply indicating that the horizontal height of the first feature is less than that of the second feature. Additionally, terms such as "front and back," "left and right," and "both ends," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention.

[0028] In the description of this utility model, the reference to terms such as "this embodiment," "some embodiments," etc., indicates that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
