Description

Technical Field

[0001] This application relates to, but is not limited to, the field of automotive parts technology, and in particular to an assembly tooling and method of using frameless car door glass. Background Technology

[0002] With the development of the automotive industry and the improvement of people's aesthetics, frameless car doors have appeared on the market due to their beautiful appearance. Frameless car door glass usually adopts a curved design and is designed to move up and down. Cars with frameless doors have rubber seals on the door frame. After the door glass moves to the highest point, its upper edge needs to match the rubber seal. Therefore, the installation position of the door glass has strict requirements during the production of frameless car doors. This makes the installation and adjustment of the door glass a difficult point in the design and manufacturing process of frameless car doors. Its assembly structure will directly affect the surface difference and gap of the door glass, affecting the appearance quality and refinement of the vehicle.

[0003] In related technologies, the assembly fixtures for frameless car door glass typically use a glass lifting mechanism to adjust the door glass. The installation position of the door glass in frameless car doors is usually determined by manual observation or by setting up a positioning mechanism. When the door glass is against the positioning mechanism, the installation is complete.

[0004] In related technologies, manually observing the installation position of the car door glass can lead to inaccurate installation, reducing installation precision and the automation level of the assembly tooling. However, if the door glass is positioned using a positioning mechanism, the glass may deform if it rests against the mechanism, affecting the quality of the door glass. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an assembly fixture and method for using frameless car door glass, which improves installation accuracy, enhances the automation level of the assembly fixture, and reduces the possibility of deformation of the car door glass.

[0006] In a first aspect, embodiments of this application provide an assembly fixture for a frameless car door glass, including a base, an adjustment mechanism, and a detection mechanism. The base is used to fix the frameless car door, and a lifting mechanism for connecting the car door glass is fixed on the frameless car door. The adjustment mechanism is fixed on the base and is used to adjust the position of the car door glass relative to the frameless car door. The detection mechanism is disposed on the base and is used to obtain the position of the car door glass relative to the frameless car door along a first direction and a second direction. The adjustment mechanism includes a control module, which is electrically connected to the detection mechanism. The first direction is the thickness direction of the car door glass, and the second direction is the extension direction of the car door glass surface. The first direction and the second direction have an included angle.

[0007] The frameless door glass assembly fixture provided in this application embodiment has a detection mechanism on its base. This detection mechanism can acquire the position of the door glass relative to the frameless door along a first direction and a second direction. The control module is electrically connected to the detection mechanism, and then the adjustment mechanism adjusts the position of the door glass relative to the frameless door until the door glass is installed in the correct position on the frameless door, thus completing the installation. Compared to related technologies that rely on manual observation of the door glass's position on the frameless door, this application embodiment improves installation accuracy and increases the automation level of the assembly fixture by setting up a detection mechanism that is electrically connected to the control module in the adjustment mechanism to adjust the position of the door glass relative to the frameless door until it is installed in the correct position. Compared to related technologies that use a positioning mechanism to snap the door glass into place, allowing the door to be installed in the frameless door position, this embodiment uses a detection mechanism electrically connected to the control module in the adjustment mechanism to adjust the position of the door glass relative to the frameless door until it is correctly installed. The adjustment mechanism is fixed to a base, avoiding the problem of the adjustment mechanism being mounted on the door glass, which would result in poor rigidity and reduce the possibility of deformation. In other words, the frameless door glass assembly fixture provided in this embodiment improves installation accuracy, increases the automation level of the assembly fixture, and reduces the possibility of door glass deformation.

[0008] In one possible implementation provided in this application embodiment, the detection mechanism includes a first detection element and a second detection element. The first detection element is used to obtain the position of the door glass relative to the frameless door along a first direction, and the second detection element is used to obtain the position of the door glass relative to the frameless door along a second direction.

[0009] In one possible implementation provided in this application embodiment, the adjustment mechanism includes a first adjustment member, which is electrically connected to the control module and is used to adapt to the glass adjustment hole on the door glass.

[0010] In one possible implementation provided in this application embodiment, the adjustment mechanism includes a second adjustment member, which is electrically connected to the control module. The second adjustment member drives the threaded fastener of the lifting mechanism fixed on the frameless door to rotate around its own axis, wherein the axial direction of the threaded fastener is the same as the first direction.

[0011] In one possible implementation provided in this application embodiment, the control module is used to electrically connect with the fixing member of the lifting mechanism to drive the fixing member to move in a second direction relative to the lifting guide rail on the lifting mechanism, wherein the fixing member is used to fix the door glass.

[0012] In one possible implementation provided in this application embodiment, a positioning mechanism is provided on the base. The positioning mechanism includes a clamping member and a positioning pin. The clamping member is rotatably connected to the base and is used to clamp the frameless car door between the clamping member and the base. The positioning pin is fixed on the base and is used to extend into the positioning hole of the frameless car door.

[0013] Secondly, embodiments of this application provide a method for adjusting the door glass using the assembly fixture for a frameless door as described in any embodiment of the first aspect, comprising:

[0014] The lifting mechanism connected to the door glass is fixed to the frameless door;

[0015] Secure the frameless door to the base;

[0016] The testing agency obtains the position of the door glass relative to the frameless door.

[0017] The adjustment mechanism adjusts the position of the door glass relative to the frameless door.

[0018] The usage method provided in this application embodiment, by utilizing the frameless door assembly fixture in any embodiment of the first aspect, has the same technical effect. That is, it improves installation accuracy, increases the automation level of the assembly fixture, and reduces the possibility of door glass deformation.

[0019] In one possible implementation provided in this application embodiment, the adjustment mechanism includes a first adjustment member, which is electrically connected to the control module, and a glass adjustment hole is provided on the door glass;

[0020] The steps for adjusting the position of the frameless door include:

[0021] The first adjustment component is adapted to the glass adjustment hole on the door glass.

[0022] In one possible implementation provided in this application embodiment, the lifting mechanism includes two fixing members and a lifting guide rail. The lifting guide rail is fixed to the frameless car door, the fixing members fix the car door glass, and the control module is electrically connected to the two fixing members. The second direction includes the length direction and the width direction.

[0023] After the first adjustment component is fitted with the door glass adjustment hole, the following steps are included:

[0024] Control the two fixed parts to move the same distance along the length direction relative to the corresponding lifting guide rail, so that the door glass moves along the length direction relative to the frameless door.

[0025] Control the two fixed parts to move the same distance along the width direction relative to the lifting guide rail, so that the door glass moves along the width direction relative to the frameless door;

[0026] One of the fixing components is controlled to move a first distance relative to the lifting guide rail along the width direction, and the other fixing component is controlled to move a second distance relative to the lifting guide rail along the width direction, so that the door glass rotates relative to the frameless door around the first direction.

[0027] In one possible implementation provided in this application embodiment, the adjustment mechanism includes a second adjustment member, which is electrically connected to the control module. The lifting mechanism is fixed to the frameless door by four bolt fasteners, the axial direction of the bolt fasteners is the same as the first direction, and the four bolt fasteners are arranged in a rectangular shape.

[0028] Following the step of aligning the first adjusting component with the door glass adjusting hole, the following steps are also included:

[0029] The second adjusting component drives four threaded fasteners to rotate around their own axis to produce the same distance, so that the door glass moves relative to the frameless door in the first direction.

[0030] The second adjusting component drives the two threaded fasteners on the first side to rotate around their own axis to generate a third distance, and drives the two threaded fasteners on the second side to rotate around their own axis to generate a fourth distance. The first and second sides are distributed along the length direction so that the door glass rotates relative to the frameless door around the length direction.

[0031] The second adjusting component drives the two threaded fasteners on the third side to generate a fifth distance around their own axis, and drives the two threaded fasteners on the fourth side to rotate around their own axis to generate a sixth distance. The third and fourth sides are distributed along the width direction so that the door glass rotates relative to the frameless door around the width direction. Attached Figure Description

[0050] This application provides an assembly fixture for frameless car door glass, referring to... Figure 1 Among them, frameless doors 5 have advantages such as beautiful appearance. The door glass 6 installed on the frameless door 5 usually adopts a curved design and is designed to move up and down. Cars using frameless doors 5 have rubber seals on their door frames. After the glass moves to its highest point, its upper edge needs to match the rubber seal. Therefore, the installation position of the door glass 6 is subject to strict requirements during the production of frameless doors 5. This makes the installation and adjustment of the door glass 6 a difficult point in the design and manufacturing process of frameless doors 5. Its assembly structure will directly affect the surface difference and gap of the door glass 6, affecting the appearance quality and refinement of the vehicle.

[0051] Specifically, the assembly fixture for the frameless door glass provided in this application embodiment refers to... Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a base 1, an adjustment mechanism 2, and a detection mechanism 3. The base 1 is used to fix the frameless door 5, and the lifting mechanism 7 of the door glass 6 is fixedly connected to the frameless door 5. The adjustment mechanism 2 is fixed on the base 1 and is used to adjust the position of the door glass 6 relative to the frameless door 5. The detection mechanism 3 is set on the base 1 and is used to obtain the position of the door glass 6 relative to the frameless door 5 along a first direction A and a second direction B. The adjustment mechanism 2 includes a control module, and the control module and the detection mechanism 3 are electrically connected. The first direction A is the thickness direction of the door glass, and the second direction B is the extension direction of the surface of the door glass 6. The first direction A and the second direction B have an included angle.

[0052] Because a detection mechanism 3 is set on the base 1, the detection mechanism 3 can obtain the position of the door glass 6 relative to the frameless door 5. The control module and the detection mechanism 3 are electrically connected, and then the adjustment mechanism 2 is used to adjust the position of the door glass 6 relative to the frameless door 5 until the door glass 6 is installed in the correct position of the frameless door 5, thus completing the installation. This improves the installation accuracy and increases the automation level of the assembly tooling. In addition, without a positioning mechanism, by setting up the detection mechanism 3 and electrically connecting the detection mechanism 3 to the control module in the adjustment mechanism 2, the position of the door glass 6 relative to the frameless door 5 can be adjusted until the door glass 6 is installed in the correct position of the frameless door 5. The adjustment mechanism 2 is fixed on the frameless door 5, which avoids the problem of poor rigidity of the door glass 6 caused by setting the adjustment mechanism 2 on the door glass 6, thus reducing the possibility of deformation of the door glass 6.

[0053] The adjustment mechanism 2 adjusts the position of the door glass 6 relative to the frameless door 5, which requires a drive component to provide power. Specifically, the adjustment mechanism 2 includes a drive component that is electrically connected to the control module. The drive component is used to provide power to adjust the position of the door glass 6 relative to the frameless door 5.

[0054] Based on this, the driving component can be a motor, with the control module electrically connected to the motor. The electricity generated by the motor provides the power to adjust the position of the door glass 6 relative to the frameless door 5. Alternatively, the driving component can be an electromagnet, with the control module electrically connected to the electromagnet. The magnetic force generated by the electromagnet provides the power to adjust the position of the door glass 6 relative to the frameless door 5. Compared to an electromagnet, which suffers from the disadvantages of easily dissipating magnetic force and instability, in one feasible implementation provided in this application embodiment, the driving component is a motor. It should be noted that this application embodiment does not limit the type of driving component.

[0055] In some embodiments provided in this application, reference is made to Figure 1 , Figure 2 and Figure 4The detection mechanism 3 is mounted on the base 1, and the adjustment mechanism 2 is used to adjust the position of the door glass 6 relative to the frameless door 5. The detection mechanism 3, mounted on the base 1, is used to acquire the position of the door glass 6 relative to the frameless door 5 along the first direction A and the second direction B. The adjustment mechanism 2 includes a control module, which is electrically connected to the detection mechanism 3. Here, the detection mechanism 3 should have a theoretical preset position, and the position acquired by the detection mechanism 3 relative to the frameless door 5 along the first direction A and the second direction B should be the actual position. Therefore, the final position of the door glass 6 relative to the frameless door 5 acquired by the detection mechanism 3 should be the difference between the theoretical preset position and the actual position. This error value can be compared with the error value set within the detection mechanism 3 to determine whether the adjustment mechanism 2 should continue to adjust the position of the door glass 6 relative to the frameless door 5. If the difference is within the error value, the adjustment mechanism 2 continues to adjust the position of the door glass 6 relative to the frameless door 5; if the difference is outside the error value, the adjustment mechanism 2 does not adjust the position of the door glass 6 relative to the frameless door 5.

[0056] The testing agency 3 can obtain the position of the door glass 6 relative to the frameless door 5. To obtain the position of the door glass 6 relative to the frameless door 5, it is necessary to obtain the position of the door glass 6 relative to the frameless door 5 along the thickness direction of the door glass 6 and the extension direction along the surface of the door glass 6. Only in this way can the accurate position of the door glass 6 relative to the frameless door 5 be obtained.

[0057] Based on this, the testing mechanism 3 needs to obtain the position of the door glass 6 relative to the frameless door 5 along the thickness direction of the door glass 6 and the extension direction along the surface of the door glass 6. If the testing mechanism 3 only has one testing element, the result of obtaining the position of the door glass 6 relative to the frameless door 5 may be too long and the result may be easily confused. To this end, this application embodiment provides a preferred solution, in which the testing mechanism 3 includes a first testing element 31 and a second testing element 32. The first testing element 31 is used to obtain the position of the door glass 6 relative to the frameless door 5 along a first direction A, and the second testing element 32 is used to obtain the position of the door glass 6 relative to the frameless door 5 along a second direction B. In this way, the testing mechanism 3 can save time in obtaining the position of the door glass 6 relative to the frameless door 5 and avoid confusion in the test results.

[0058] Furthermore, since sensors are miniaturized, digitalized, intelligent, multifunctional, systematic, and networked, in order to accurately obtain the position of the door glass 6 relative to the frameless door 5 and save assembly tooling space, for example, the first detection element 31 and the second detection element 32 can be sensors. A sensor is a detection device that can sense the measured information and transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0059] Furthermore, the second direction B is the extension direction of the door glass 6, which can be divided into the length direction and the width direction of the door glass 6. Similarly, in order to further save the time of the detection mechanism 3 in obtaining the position of the door glass 6 relative to the frameless door 5 and to avoid confusion in the detection structure, this application embodiment also provides a preferred solution. The second detection element 32 may include a first sub-detection element 321 and a second sub-detection element 322. The second direction B is divided into a length direction B1 and a width direction B2. The first sub-detection element 321 is used to obtain the position of the door glass 6 relative to the frameless door 5 along the length direction B1, and the second sub-detection element 322 is used to obtain the position of the door glass 6 relative to the frameless door 5 along the width direction B2.

[0060] In some other embodiments provided in this application, reference is made to... Figure 1 , Figure 2 and Figure 4 The adjustment mechanism 2 includes a first adjustment member 21, which is electrically connected to the control module. The first adjustment member 21 is used to adapt to the glass adjustment hole 61 on the door glass 6.

[0061] Specifically, since the control module is electrically connected to the detection mechanism 3 and the first adjustment member 21 is electrically connected to the control module, the detection mechanism 3 obtains the position of the door glass 6 relative to the frameless door 5 and transmits it to the control module. The control module controls the first adjustment member 21 according to the transmission result so that the first adjustment member 21 is adapted to the glass adjustment hole 61 on the door glass 6 to adjust the position of the door glass 6 relative to the frameless door 5 along the second direction B.

[0062] The first adjusting member 21 can be a pin-like structure or a threaded fastener-like structure; this embodiment of the application does not impose any limitations on this. Compared to setting the first adjusting member 21 as a threaded fastener-like structure, setting it as a pin-like structure can save costs and processing time.

[0063] Specifically, the first adjusting member 21 is adapted to the glass adjusting hole 61 on the door glass 6. This can be achieved through image recognition technology, such as by recognizing the difference in position and color. It can also be achieved through magnetic materials, such as by setting magnetic materials that attract each other on the first adjusting member 21 and the glass adjusting hole 61 on the door glass 6. Of course, the adaptation of the first adjusting member 21 to the glass adjusting hole 61 on the door glass 6 can also be achieved through other methods.

[0064] In order to accurately position the door glass 6 relative to the frameless door 5 along the second direction B, and to avoid the door glass 6 from shaking relative to the frameless door 5 along the second direction B during the positioning process, which would result in a long positioning time for the door glass 6, this application provides a preferred solution. There are multiple first adjustment members 21, and the multiple first adjustment members 21 are used to correspond one-to-one with multiple glass adjustment holes 61 on the door glass 6.

[0065] For example, the adjustment mechanism 2 includes a second adjustment member 22, which is electrically connected to the control module. The second adjustment member 22 drives the threaded fastener of the lifting mechanism 7, which is fixed to the frameless door 5, to rotate around its own axis. The axial direction of the threaded fastener is the same as the first direction A. Specifically, since the control module is electrically connected to the detection mechanism 3, and the second adjustment member 22 is electrically connected to the control module, the detection mechanism 3 obtains the position of the door glass 6 relative to the frameless door 5 and transmits it to the control module. The control module controls the second adjustment member 22 to drive the threaded fastener to rotate around its own axis based on the transmission result, so as to adjust the position of the door glass 6 relative to the frameless door 5 along the axial direction of the threaded fastener.

[0066] For example, the threaded fastener can be a stud or a bolt. This application does not limit the specific type of fastener. In a preferred embodiment of this application, the threaded fastener is a stud. This eliminates the need to consider orientation during assembly, saving assembly time.

[0067] Specifically, before the second adjusting member 22 drives the threaded fastener to rotate around the axis of the threaded fastener, the second adjusting member 22 needs to cooperate with the threaded fastener. This cooperation process can be achieved through image recognition technology, such as by recognizing the difference in position color, or by using magnetic materials, such as by setting magnetic materials that attract each other on the second adjusting member 22 and the threaded fastener for recognition. Of course, the cooperation between the second adjusting member 22 and the threaded fastener can also be achieved through other means.

[0068] It should be further noted that there can be one or more threaded fasteners, and this application embodiment does not impose any limitation on this. If there is only one threaded fastener, only the position of the entire surface of the door glass 6 relative to the frameless door 5 along the first direction A can be adjusted, but the rotation of the entire surface of the door glass 6 relative to the frameless door 5 along the second direction cannot be adjusted. In one possible implementation provided by this application embodiment, there are multiple threaded fasteners, and the second adjusting member 22 adjusts the multiple threaded fasteners to realize the movement of the entire surface of the door glass 6 relative to the frameless door along the first direction A and the rotation around the second direction B. Here, it should be noted that there can be one second adjusting member 22, which adjusts multiple threaded fasteners, or there can be multiple second adjusting members 22, with each of the multiple second adjusting members 22 corresponding to a single threaded fastener.

[0069] For example, there may be four threaded fasteners arranged in a rectangular pattern. The control module controls the second adjusting member 22 to rotate the four threaded fasteners around their own axes to generate the same distance, so that the door glass 6 moves relative to the frameless door 5 along the first direction A. The control module also controls the second adjusting member 22 to rotate the two threaded fasteners on the first side around their own axes to generate a fourth distance. The first and second sides are distributed along the length direction B1, so that the door glass 6 rotates relative to the frameless door 5 around the length direction B1. Furthermore, the control module controls the second adjusting member 22 to rotate the two threaded fasteners on the third side around their own axes to generate a fifth distance, and to rotate the two threaded fasteners on the fourth side around their own axes to generate a sixth distance. The third and fourth sides are distributed along the width direction B2, so that the door glass 6 rotates relative to the frameless door 5 around the width direction B2. Of course, the number and distribution of the threaded fasteners can also be other, and this embodiment does not limit this.

[0070] In some other embodiments provided in this application, the lifting mechanism 7 includes a fixing member 71 and a lifting guide rail 72. The fixing member 71 is used to fix the door glass 6, and the lifting guide rail 72 is fixed on the frameless door 5. The fixing member 71 is electrically connected to the control module, and the fixing member 71 moves relative to the lifting guide rail 22 in the second direction B.

[0071] Specifically, since the control module is electrically connected to the detection mechanism 3 and the fixing member 271 is electrically connected to the control module, the detection mechanism 3 obtains the position of the door glass 6 relative to the frameless door 5 and transmits it to the control module. The control module controls the fixing member 71 according to the transmission result so that the fixing member 71 moves relative to the lifting guide rail 72 along the second direction B to adjust the position of the door glass 6 relative to the frameless door 5 along the second direction B.

[0072] The control module controls the fixing member 71 according to the transmitted results, so that the fixing member 71 moves relative to the lifting guide rail 72 along the second direction B, thereby adjusting the position of the door glass 6 relative to the frameless door 5 along the second direction B. As can be seen from the above embodiment, the second direction B is the extension direction of the door glass 6, including the length direction and the width direction of the door glass 6. Since the fixing member 71 moves relative to the lifting guide rail 72 along the second direction B, the lifting guide rail 72 needs to have a certain displacement along the length direction and the width direction of the door glass 6. The lifting guide rail 72 can be divided into two parts: a first guide rail part along the length direction of the door glass 6 and a second guide rail part along the width direction of the door glass 6. The lifting guide rail 72 can also have a certain tilt angle along the length direction of the door glass 6, so that the lifting guide rail 72 can project a certain displacement along the length direction and a certain displacement along the width direction of the door glass 6. Of course, the lifting guide rail 72 can also be in other specific embodiments, which are not limited in this application.

[0073] Compared to setting the lifting guide rail 72 to have a first guide rail along the length of the door glass 6 and a second guide rail along the width of the door glass 6, setting the lifting guide rail 72 to have a certain tilt angle along the length of the door glass 6 is more beneficial to the time it takes for the fixing member 21 to move relative to the lifting guide rail 72 in the second direction B.

[0074] Since the fastener 21 is used to fix the door glass 6, multiple fasteners 71 can be provided to enhance the stability of the fastener 21 in fixing the door glass 6. All multiple fasteners 71 are used to fix the door glass 6. In addition, since the door glass 6 is a curved surface, in order to ensure that the position of any position on the curved surface relative to the frameless door 5 along the second direction B can be adjusted, multiple lifting guide rails 72 can be provided. The multiple lifting guide rails 72 correspond one-to-one with the multiple fasteners 71. The different positions of the multiple fasteners 21 on the multiple lifting guide rails 22 will enable the door glass 6 to rotate around the first direction A.

[0075] For example, when there are two fixing members 71 and two corresponding lifting guide rails 72, the control module controls the two fixing members 71 to move the same distance along the length direction B1 relative to the corresponding lifting guide rail 72, and controls the door glass 6 to move relative to the frameless door 5 along the length direction B1; the control module controls the two fixing members 71 to move the same distance along the width direction B2 relative to the corresponding lifting guide rail 72, so that the door glass 6 moves relative to the frameless door 5 along the width direction B2; the control module controls one of the fixing members 71 to move a first distance along the width direction B2 relative to the corresponding lifting guide rail 72, and controls the other fixing member 71 to move a second distance along the width direction B2 relative to the corresponding lifting guide rail, so that the door glass 6 rotates relative to the frameless door around the first direction B.

[0076] As can be seen from the above embodiments, the glass lifting mechanism 2 realizes the movement of the door glass 6 along the first direction A and the second direction B, as well as the rotation around the first direction A and the second direction B, thereby realizing the adjustment of the door glass 6 with full degrees of freedom and ensuring the consistency of assembly.

[0077] It should be further noted that the fixing method of the fastener 21 for fixing the door glass 6 can be a non-removable fixing such as adhesive or welding, or a detachable connection such as threaded connection or snap-fit. This application embodiment does not limit this method. In a preferred embodiment of this application, the fastener 71 is a clamping piece, which acts on the surface of the door glass 6 along its thickness direction to clamp the door glass 6.

[0078] In addition, bolt holes are provided on both the fastener 71 and the door glass 6. The axis of the bolt hole on the fastener 71 is collinear with the axis of the bolt hole on the door glass 6 to ensure that the bolt can pass through the bolt hole on the fastener 21 and the bolt hole on the door glass 6 in sequence, thus fixing the door glass 6 to the frameless door 5.

[0079] To further improve the automation level of the assembly fixture for frameless door glass, a bolt tightening arm can be set on the base 1. This bolt tightening arm allows the bolt to pass sequentially through the bolt holes on the fixing component 71 and the bolt holes on the door glass 6, fixing the door glass 6 to the frameless door 5. The positional difference between the door glass 6 and the frameless door 5 can be compared with the error value set in the detection mechanism 3 to determine whether the adjustment mechanism 2 should continue adjusting the position of the door glass 6 relative to the frameless door 5. If the difference is within the error value, the adjustment mechanism 2 stops adjusting the position of the door glass 6 relative to the frameless door 5, and then the bolt tightening arm aligns the bolt with the bolt holes on the fixing component 21 and the door glass 6, performing the bolt tightening action. If the difference is outside the error value, the adjustment mechanism 2 continues adjusting the position of the door glass 6 relative to the frameless door 5 until the difference is within the error value, at which point the bolt tightening arm aligns the bolt with the bolt holes on the fixing component 71 and the door glass 6, performing the bolt tightening action.

[0080] The process of the bolts passing through the bolt holes on the fastener 71 and the door glass 6 in sequence can be achieved through image recognition technology, such as by recognizing the difference in position color, or by using magnetic materials, such as by setting magnetic materials that attract each other on the bolt tightening arm or the bolt and bolt hole. Of course, other methods can also be used to complete the engagement of the bolt tightening arm or the bolt and bolt hole.

[0081] For example, the base 1 is used to fix the frameless car door 5. The base 1 can fix the frameless car door 5 in a non-removable manner such as adhesive bonding or welding, or in a detachable manner such as bolt connection or snap-fit. This application embodiment does not limit this. Compared with non-removable fixing, the use of detachable fixing can realize the reuse of assembly tooling and does not damage the frameless car door 5.

[0082] This application embodiment employs a detachable fixing method and provides a preferred solution. A positioning mechanism 4 is provided on the base 1. The positioning mechanism 4 includes a clamping member 41 and a positioning pin 42. The clamping member 41 is rotatably connected to the base 1 and is used to clamp the frameless car door 5 between the clamping member 41 and the base 1. The positioning pin 42 is fixed to the base 1 and is used to extend into the positioning hole of the frameless car door 5. By clamping the frameless car door 5 between the clamping member 41 and the base 1, and by extending the positioning pin 42 into the positioning hole of the frameless car door 5, the frameless car door 5 is fixed to the base 1 in multiple ways.

[0083] In addition, to further enhance the stability of the frameless door 5 fixed to the base 1, multiple clamping members 41 and positioning pins 42 can be provided, and the positions of the multiple clamping members 41 and positioning pins 42 can be set according to the shape of the frameless door 5. It should be noted that the embodiments of this application do not limit the number and distribution of clamping members 41 and positioning pins 42.

[0084] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 This application also provides a method for adjusting the door glass using an assembly fixture for frameless door glass, specifically including:

[0085] Step S1: Secure the lifting mechanism connected to the door glass to the frameless door;

[0086] Step S2: Fix the frameless door to the base;

[0087] Step S3: The testing agency obtains the position of the door glass relative to the frameless door;

[0088] Step S4: Adjust the position of the door glass relative to the frameless door using the adjustment mechanism.

[0089] Through the electrical connection between the detection mechanism and the adjustment mechanism control module, the adjustment mechanism adjusts the position of the door glass relative to the frameless door according to the structure of the detection mechanism, improving installation accuracy, increasing the automation level of the assembly tooling, and reducing the possibility of door glass deformation.

[0090] Furthermore, referring to Figure 1 , Figure 3 , Figure 4 and Figure 6 The adjustment mechanism also includes a first adjustment component, which is electrically connected to the control module, and a glass adjustment hole is provided on the door glass;

[0091] Step S4, adjusting the position of the door glass relative to the frameless door, includes step S41: controlling the first adjusting member to align with the adjusting hole on the door glass. This allows adjustment of the door glass's position relative to the frameless door along a second direction.

[0092] Furthermore, referring to Figure 1 , Figure 3 , Figure 4 and Figure 7 The lifting mechanism includes two fixing parts and a lifting guide rail. The lifting guide rail is fixed to the frameless door, and the fixing parts fix the door glass. The control module is electrically connected to the two fixing parts. The second direction includes the length direction and the width direction.

[0093] Step S42 is included after step S41, in which the first adjusting member is adapted to the door glass adjusting hole:

[0094] Control the two fixed parts to move the same distance along the length of the lifting guide rail so that the door glass moves along the length of the frameless door.

[0095] Control the two fixed parts to move the same distance along the width direction relative to the lifting guide rail, so that the door glass moves along the width direction relative to the frameless door;

[0096] One of the fixing components is controlled to move a first distance relative to the lifting guide rail along the width direction, and the other fixing component is controlled to move a second distance relative to the lifting guide rail along the width direction, so that the door glass rotates relative to the frameless door around the first direction. In this way, the position of the door glass relative to the frameless door along the second direction and the rotation around the first direction can be adjusted.

[0097] Furthermore, referring to Figure 1 , Figure 3 , Figure 4 and Figure 8 The adjustment mechanism includes a second adjustment component, which is electrically connected to the control module. The lifting mechanism is fixed to the frameless door by four bolt fasteners. The axial direction of the bolt fasteners is the same as the first direction, and the four bolt fasteners are arranged in a rectangular shape.

[0098] After step S41, the first adjusting member is adapted to the door glass adjusting hole, step S43 is included: controlling the second adjusting member to drive the four threaded fasteners to generate the same distance around their own axis, so that the door glass moves relative to the frameless door in the first direction.

[0099] The second adjusting component drives the two threaded fasteners on the first side to rotate around their own axis to generate a third distance, and drives the two threaded fasteners on the second side to rotate around their own axis to generate a fourth distance. The first and second sides are distributed along the length direction so that the door glass rotates relative to the frameless door around the length direction.

[0100] The second adjusting component drives the two threaded fasteners on the third side to rotate around their own axis to generate a fifth distance, and drives the two threaded fasteners on the fourth side to rotate around their own axis to generate a sixth distance. The third and fourth sides are distributed along the width direction so that the door glass can rotate relative to the frameless door around the width direction. In this way, the position of the door glass relative to the frameless door along the first direction and its rotation around the second direction can be adjusted.

[0101] It should be noted that steps S42 and S43 are not in any particular order during the adjustment process, and can be selectively adjusted based on the position of the door glass relative to the frameless door obtained by the testing agency.

[0102] Furthermore, referring to Figure 1 , Figure 3 , Figure 4 and Figure 9 The assembly fixture for the door glass also includes a bolt tightening arm, on which bolts are applied. Bolt holes are provided on both the fastener and the door glass. After completing steps S42 and S43, the following steps are also included:

[0103] Step S5: The control module determines whether the door glass has reached the correct position of the frameless door. If not, proceed to steps S42 and S43.

[0104] Step S6: If so, the bolt tightening lever arm aligns the bolt with the bolt holes on the fastener and the door glass, and the bolt tightening action is performed. In this way, the fully automated adjustment of the door glass is achieved.

[0105] It should be noted that the specific usage method of the frameless door glass assembly fixture listed in the embodiments of this application is only one method of using the frameless door glass assembly fixture, and other specific usage methods are also possible. This application does not limit the specific usage methods. Through the above implementation methods, the installation progress of the door glass is improved, the consistency of assembly is ensured, and the degree of automation is enhanced.

[0106] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
