Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile painting equipment, and in particular to an electrophoretic balancing tool for an automobile trunk lid. Background Art
[0002] In the field of automobile production, the anti-corrosion and anti-rust treatment of the car body is of vital importance. The traditional method mainly adopts electrophoresis treatment in the paint shop to achieve anti-corrosion protection of the car body through the movement of charged particles under the action of the electric field. However, this process involves multiple process water tanks. When the car body enters these water tanks for cleaning and electrophoresis operations, the door cover of the car body needs to be limited and fixed to prevent collision and deformation caused by opening; at the same time, the limit angle of the door cover needs to be set reasonably to ensure that the tank liquid can be completely discharged when the vehicle leaves the tank.
[0003] In the related art, when the car body is subjected to electrophoresis process, a corresponding balancing tool is generally used to fix the trunk lid of the car. However, in the existing balancing tool, the elastic arm is fixed to the support rod by welding, so that the tool needs to use welding equipment during the production process, which is inefficient and costly. Utility Model Content
[0004] Based on this, it is necessary to provide a tooling for fixing the elastic arm in a non-welding manner to improve production efficiency and reduce production costs.
[0005] A car trunk lid electrophoresis balancing tool comprises: a connecting rod for connecting a car body; a connecting plate installed at one end of the connecting rod away from the car body; a connecting piece installed on the connecting plate; an elastic piece, comprising an integrally arranged winding section, a first elastic arm and a second elastic arm, the winding section is wound around the connecting piece and is limited to the connecting plate by the connecting piece, the first elastic arm and the second elastic arm are respectively connected to two ends of the winding section, and the first elastic arm and the second elastic arm can undergo elastic deformation in response to external force, and are used to extend into a process hole on the trunk lid and clamp the trunk lid.
[0006] In one embodiment, the connecting member includes a threaded member and a threaded sleeve, a threaded hole is opened on the connecting plate, one end of the threaded member is penetrated by the threaded hole to form a connecting section, and the threaded sleeve is threadedly connected to the connecting section; wherein the elastic member is wrapped around the connecting section and, under the action of the threaded sleeve, abuts against and is limited to the connecting plate.
[0007] It is understandable that the combination of the threaded member and the threaded sleeve makes assembly and disassembly more convenient and quicker.
[0008] In one of the embodiments, a baffle is provided on the circumference of the threaded sleeve, and along the axial direction of the threaded member, one end of the winding section abuts against and is limited at the connecting plate, and the other end abuts against and is limited at the baffle.
[0009] It can be understood that by setting the baffle, the contact area between the threaded sleeve and the winding section can be increased in the radial direction of the threaded sleeve, thereby effectively improving the limiting effect on the elastic part, so that the elastic part can be stably limited on the connecting plate, so as to further improve the stability of the trunk cover supported by the electrophoretic balancing tooling of the automobile trunk cover.
[0010] In one embodiment, the elastic member is configured as spring steel.
[0011] It is understandable that spring steel itself has high tensile strength and elastic limit. Here, by utilizing the properties of spring steel, the elastic member can also have corresponding advantages, so that the elastic member has better stability and longer service life.
[0012] In one of the embodiments, the connecting plate is provided with two spaced-apart stop bars, and the first elastic arm and the second elastic arm both extend through the gap between the two stop bars; and the first elastic arm is limitedly abutted against one of the stop bars, and the second elastic arm is limitedly abutted against the other stop bar.
[0013] It is understandable that the stop bar serves to limit the first elastic arm and the second elastic arm, so as to prevent the first elastic arm and the second elastic arm from being misaligned due to frequent use, thereby affecting the support and fixation of the luggage compartment cover.
[0014] In one embodiment, the minimum distance between an end of the first elastic arm away from the winding section and an end of the second elastic arm away from the winding section is L, and L is ≥ 30 mm.
[0015] It is understandable that when the first elastic arm and the second elastic arm extend into the process hole on the trunk lid, the first elastic arm and the second elastic arm need to be pressed toward each other to deform, so as to ensure that the first elastic arm and the second elastic arm can extend into the process hole. Therefore, the elastic force of the first elastic arm and the second elastic arm actually depends on the deformation of the first elastic arm and the second elastic arm. The larger the deformation, the greater the force of clamping the trunk lid. Therefore, in order to ensure that the first elastic arm and the second elastic arm can better clamp the trunk lid, the present application sets L to L≥30mm.
[0016] In one of the embodiments, a mounting plate is provided at one end of the connecting rod away from the connecting plate, and the mounting plate is used to fit with the vehicle body and be fixed to the vehicle body by fasteners.
[0017] It can be understood that, by fitting and fixing the mounting plate to the vehicle body, the entire electrophoretic balancing tooling for the automobile trunk lid can be stably mounted on the vehicle body, thereby improving the stability of the tooling as a whole in supporting the trunk lid.
[0018] In one embodiment, a mounting hole is formed on the mounting plate, and one end of the fastener passes through the mounting hole and is connected to the vehicle body.
[0019] Wherein, the position of the fastener in the mounting hole can be adjusted.
[0020] It is understandable that the position of the fastener in the mounting hole can be adjusted, so that the position of the mounting plate on the vehicle body can be adjusted, so that the height of the entire automobile trunk lid electrophoresis balancing tooling supporting the trunk lid can be adjusted. In this way, the automobile trunk lid electrophoresis balancing tooling in the present application can adapt to the support of different distances between the process hole and the trunk lid, effectively improving the scope of use of the present application and the compatibility of the product.
[0021] In one embodiment, the mounting hole is configured as a strip-shaped hole, and the fastener can be changed in position along the length direction of the strip-shaped hole.
[0022] In one embodiment, the mounting plate is connected to the connecting rod by welding.
[0023] Compared with the prior art, the electrophoretic balancing tooling for the automobile trunk lid is provided with a connecting piece and a winding section, so that during the assembly process, it is only necessary to sleeve the winding section of the elastic piece on the connecting piece, and then limit the elastic piece as a whole on the connecting plate through the connecting piece, so as to realize the assembly between the elastic piece and the connecting rod. This structure is not only simple and has high assembly efficiency, but also does not require additional welding equipment and has low cost. At the same time, through the provision of the winding section, the elastic piece can be stably connected to the connecting piece, which can not only provide a higher elastic force, but also help to improve the stability of the elastic piece during the clamping process.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.
[0035] like Figure 1 As shown, the present application provides a car trunk lid electrophoresis balancing tool 100, which is mainly used to support the trunk lid in the automobile electrophoresis process so that the gap between the trunk lid and the car body remains unchanged, thereby facilitating the timely discharge of the medium.
[0036] Specifically, combined Figure 2 The electrophoretic balancing tooling 100 for the automobile trunk lid includes a connecting rod 10, a connecting plate 20, a connecting member 30 and an elastic member 40. The connecting rod 10 is used to be connected to the body of the automobile; the connecting plate 20 is installed at the end of the connecting rod 10 away from the body; the connecting member 30 is installed on the connecting plate 20; the elastic member 40 includes an integrally arranged winding section 41, a first elastic arm 42 and a second elastic arm 43. The winding section 41 is wound around the connecting member 30 and is limited to the connecting plate 20 by the connecting member 30. The first elastic arm 42 and the second elastic arm 43 are respectively connected to the two ends of the winding section 41, and the first elastic arm 42 and the second elastic arm 43 can undergo elastic deformation in response to external force, and are used to extend into the process hole (not shown) on the trunk lid and clamp the trunk lid. It is understandable that, by providing the connecting member 30 and the winding section 41, during the assembly process, it is only necessary to sleeve the winding section 41 of the elastic member 40 on the connecting member 30, and then limit the elastic member 40 as a whole on the connecting plate 20 through the connecting member 30, so as to realize the assembly between the elastic member 40 and the connecting rod 10. This structure is not only simple and has high assembly efficiency, but also does not require additional welding equipment and has low cost. At the same time, by providing the winding section 41, the elastic member 40 can be stably connected to the connecting member 30, which can not only provide a higher elastic force, but also help to improve the stability of the elastic member 40 during the clamping process.
[0037] It should be explained that the car body in the present application is subjected to a 360° flip electrophoresis process. The car body is flipped 180° to face the bottom of the car upward when entering the tank, and then flipped to a normal angle after completing the process operation. The present application provides a winding section 41 and a connector 30, which can increase a more stable clamping force, so that the car body can be flipped in time, and can also better ensure that the trunk cover is well supported, preventing the trunk cover from deforming during electrophoresis and preventing the problem of uneven gaps on the trunk cover.
[0038] Please continue to refer to Figure 1 and Figure 2 The connecting rod 10 plays a basic connection and support role, and its purpose is to connect the body of the car and the connecting plate 20.
[0039] The connecting rod 10 can be cut from steel bars and the like, which is convenient for obtaining materials and has high structural strength.
[0040] In one embodiment, a mounting plate 11 is provided at one end of the connecting rod 10 away from the connecting plate 20, and the mounting plate 11 is used to fit with the vehicle body and be fixed to the vehicle body by fasteners (not shown). That is, by providing the mounting plate 11, the contact area between the connecting rod 10 and the vehicle body can be increased, so that the entire electrophoresis balancing tool 100 for the automobile trunk lid can be more stably installed on the vehicle body, thereby improving the overall stability of the trunk lid support.
[0041] Preferably, the mounting plate 11 and the connecting rod 10 can be connected by welding, threaded connection, etc. In this embodiment, the mounting plate 11 and the connecting rod 10 are connected by welding.
[0042] Furthermore, a mounting hole 111 is provided on the mounting plate 11, and one end of the fastener passes through the mounting hole 111 and is connected to the vehicle body; wherein, the position of the fastener in the mounting hole 111 can be adjusted. In this way, the position of the mounting plate 11 on the vehicle body can be adjusted, so that the height of the entire automobile trunk lid electrophoresis balancing tooling supporting the trunk lid can be adjusted. In this way, the automobile trunk lid electrophoresis balancing tooling in the present application can adapt to the support of different distances between the process hole and the trunk lid, effectively improving the scope of use of the present application.
[0043] Preferably, the mounting hole 111 is configured as a strip hole, and the fastener can be changed in position along the length direction of the strip hole. Here, the length direction of the strip hole is the vertical direction of the car. Of course, it is not limited thereto, and the number of mounting holes 111 can also be multiple, and the multiple mounting holes 111 are arranged along the vertical direction of the car, and the fastener can be adjusted in different mounting holes 111.
[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the connecting plate 20 can be made of steel plate, which is convenient to obtain and has high structural strength.
[0045] Optionally, the connection plate 20 and the connection rod 10 can be connected by welding, threaded connection, etc. In this embodiment, the connection plate 20 and the connection rod 10 are connected by welding, and when the connection rod 10 is made of steel such as steel bars, it is more conducive to welding and fixing the connection plate 20 and the connection rod 10.
[0046] In one embodiment, two spaced-apart stop bars 21 are provided on the connecting plate 20, that is, a gap is formed between the two stop bars 21, and the first elastic arm 42 and the second elastic arm 43 both extend through the gap, and the first elastic arm 42 is limitedly matched with one of the stop bars 21, and the second elastic arm 43 is limitedly matched with the other stop bar 21. In this way, the first elastic arm 42 and the second elastic arm 43 can be limited in the stop bar 21, preventing the first elastic arm 42 and the second elastic arm 43 from being misaligned due to frequent use, thereby maintaining the function of supporting and fixing the trunk lid.
[0047] Preferably, the two stop bars 21 can be formed by bending the two sides of the connecting plate 20 to form an integrated structure. In this way, the stop bar 21 and the connecting plate 20 become an integral whole, so that the stop bar 21 can withstand a greater force and has a higher structural strength. Of course, the stop bar 21 can also be set as a separate type from the connecting plate 20, in which case the stop bar 21 can be fixed to the connecting plate 20 by welding, clamping, threading, etc.
[0048] like Figure 1 and Figure 2 As shown, the connecting member 30 includes a threaded member 31 and a threaded sleeve 32. The connecting plate 20 is provided with a threaded hole 22. One end of the threaded member 31 passes through the threaded hole 22 to form a connecting section 311, and the threaded member 31 is threadedly connected to the threaded hole 22. The threaded sleeve 32 is threadedly connected to the connecting section 311, and the winding section 41 is wound around the connecting section 311, and abuts against and is limited to the connecting plate 20 under the action of the threaded sleeve 32. It can be understood that the cooperation between the threaded member 31 and the threaded sleeve 32 makes disassembly and assembly more convenient and quick, and it can quickly realize the positioning of the winding section 41.
[0049] As preferably, the threaded member 31 is set as a bolt. The threaded sleeve 32 is set as a nut, which is convenient for material collection. Of course, the threaded member 31 can also be made by cutting a threaded pipe.
[0050] Furthermore, a baffle 33 is provided in the circumferential direction of the threaded sleeve 32, and along the axial direction of the threaded member 31, one end of the winding section 41 abuts against and is limited to the connecting plate 20, and the other end abuts against and is limited to the baffle 33. That is, a gap is formed between the baffle 33 and the connecting plate 20, so that the winding section 41 is limited in the gap by the baffle 33. It can be understood that, by setting the baffle 33, the contact area between the threaded sleeve 32 and the winding section 41 can be increased in the radial direction of the threaded sleeve 32, thereby effectively improving the limiting effect on the elastic member 40, so that the elastic member 40 can be stably limited on the connecting plate 20, so as to further improve the stability of the automobile trunk lid electrophoresis balancing tool 100 in supporting the trunk lid.
[0051] In one embodiment, the elastic member 40 is configured as spring steel. That is, the elastic member 40 is manufactured by processing spring steel. Here, spring steel itself has high tensile strength and elastic limit. Therefore, by utilizing the properties of spring steel, the elastic member 40 can also have corresponding advantages, so that the elastic member 40 has better stability and longer service life.
[0052] Furthermore, the winding section 41 is arranged in a spiral shape, and can be arranged in multiple turns to improve the stability of the elastic member 40 installed on the connecting member 30.
[0053] like Figure 3 As shown, the minimum distance between the end of the first elastic arm 42 away from the winding section 41 and the end of the second elastic arm 43 away from the winding section 41 is L, and L≥30mm. It should be explained that when the first elastic arm 42 and the second elastic arm 43 extend into the process hole on the trunk lid, the first elastic arm 42 and the second elastic arm 43 need to be pressed toward each other to deform so as to ensure that the first elastic arm 42 and the second elastic arm 43 can extend into the process hole. Therefore, the elastic force of the first elastic arm 42 and the second elastic arm 43 actually depends on the deformation of the first elastic arm 42 and the second elastic arm 43. The larger the deformation, the greater the force of clamping the trunk lid. Therefore, in order to ensure that the first elastic arm 42 and the second elastic arm 43 can better clamp the trunk lid, the present application sets the value of L to L≥30mm.
[0054] Here, the value of L can be 30mm, 40mm, 50mm, 60mm, 70mm, etc. Of course, the value of L needs to take into account operability and cannot be too large. Generally speaking, the value of L is not greater than 100mm, because if it exceeds 100mm, it may require multiple people or two hands to operate, and the convenience of operation will be compromised.
[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0056] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
