Description

Technical Field

[0001] This utility model relates to the field of connection tool technology, and in particular to a handheld device for preventing incorrect installation of a plug for an automotive temperature control sensor. Background Technology

[0002] In existing technologies, two common methods for preventing assembly errors in temperature control sensor plugs are structural error prevention and tooling error prevention:

[0003] Error-proofing structure: An error-proofing structure is added between the temperature control sensor cover and its mounting mating parts. If incorrect installation occurs, this structure will directly restrict the assembly process, preventing the cover from being installed correctly.

[0004] Error-proofing tooling: In the cap assembly process, a special error-proofing tooling is configured. During assembly, the mating parts of the cap are first fixed to the tooling, and then the cap is installed; if misassembly occurs, the limiting structure on the tooling will prevent the cap from being installed normally.

[0005] However, the above error prevention solutions have the following limitations:

[0006] If the assembly line has already experienced problems with mis-installed caps, adopting a structural error prevention solution for rectification requires simultaneous modification of multiple related molds, such as injection molds, female mold forming molds, and automatic edge-wrapping molds. This not only results in high modification costs but also a long rectification period.

[0007] While tooling error prevention solutions can avoid mold modifications, dedicated error prevention tooling itself has a high purchase cost and a long processing and manufacturing cycle.

[0008] In summary, both existing solutions significantly increase development costs and weaken the product's market competitiveness. Utility Model Content

[0009] To address the aforementioned issues, this utility model provides a handheld device for preventing incorrect installation of a car temperature control sensor cover. Through structural adaptation between the handheld body and the sliding grooves on both sides of the sensor bracket and the limiting groove on the main body of the temperature control sensor cover, as well as structural adaptation between the contoured temperature control head and the reserved hole of the temperature control head, the device effectively prevents incorrect installation of the temperature control sensor cover when it is installed on the lower panel of the dashboard. It is simple in structure, easy to use, and inexpensive.

[0010] To achieve the above objectives, this utility model provides a handheld device for preventing incorrect installation of a car temperature control sensor cover, used to install the temperature control sensor cover on the inside of the lower panel of the dashboard.

[0011] A sensor bracket is pre-installed on the inner side of the instrument panel lower guard plate. Sliding grooves are provided on both sides of the sensor bracket.

[0013] The handheld body adopts a cuboid structure. The width of the handheld body is adapted to the length between the sliding grooves on both sides of the sensor bracket. The thickness of the handheld body is adapted to the width of the sliding groove. Moreover, the width of the handheld body is greater than the diameter of the edge of the annular cover. The thickness of the handheld body is adapted to the width of the body limiting slot.

[0014] The contoured temperature control head is disposed at the end of the handheld body. The contoured temperature control head can be inserted into the reserved hole of the temperature control head to limit the position of the temperature control sensor cover and the anti-misinstallation handheld device. The handheld body is inserted into the main body limiting slot to limit the angle between the temperature control sensor cover and the anti-misinstallation handheld device.

[0015] When the user holds the handheld body to install the temperature control sensor cover on the inside of the lower panel of the instrument panel, the handheld body is inserted into the groove to define the position and angle of the temperature control sensor cover and the sensor bracket.

[0016] In the above technical solution, preferably, the anti-misassembly handheld device further includes a positioning boss, which is disposed at the same end of the handheld body as the contour temperature control head;

The single-sided gap between the positioning boss and the positioning groove is 0.1 to 0.3 mm. The positioning boss is inserted into the positioning groove to limit the position of the temperature control sensor plug and the anti-misinstallation handheld device.

[0018] In the above technical solution, preferably, the positional relationship between the contoured temperature control head and the positioning boss is the same as the positional relationship between the reserved hole of the temperature control head and the positioning groove. The temperature control sensor plug can be positioned and installed on the anti-misinstallation handheld device through the positioning groove, and the contoured temperature control head can be inserted into the reserved hole of the temperature control head.

[0019] In the above technical solution, preferably, when the temperature control sensor plug is installed on the anti-misinstallation handheld device, the height of the profiled temperature control head protrudes at least 2 mm beyond the reserved hole of the temperature control head.

[0020] In the above technical solution, preferably, the lower instrument panel is provided with a cover mounting hole. When the user holds the handheld body to install the temperature control sensor cover on the inside of the lower instrument panel, the temperature control sensor cover is located in the cover mounting hole, and the profiled temperature control head can protrude from the surface of the lower instrument panel.

[0021] In the above technical solution, preferably, the cuboid edge of the handheld body is provided with a limiting guide rib, the overall size of the limiting guide rib is adapted to the slide groove of the sensor bracket, the single-sided gap between the limiting guide rib and the slide groove is 0.1 to 0.3 mm during the insertion of the handheld body along the slide groove, and the slide groove limits the position of the limiting guide rib in the direction perpendicular to the insertion direction.

[0022] In the above technical solution, preferably, when the conformal temperature control head is inserted into the pre-drilled hole of the temperature control head, the single-sided gap between the conformal temperature control head and the pre-drilled hole of the temperature control head is 0.1 to 0.3 mm.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings:

[0036] like Figures 1 to 3 As shown, a handheld device for preventing incorrect installation of a car temperature control sensor plug cover according to the present invention is used to install the temperature control sensor plug cover 1 on the inner side of the lower instrument panel 2.

[0037] A sensor bracket 3 is pre-installed on the inner side of the instrument panel lower guard plate 2. The sensor bracket 3 has sliding grooves 31 on both sides. The temperature control sensor plug 1 has a temperature control head reserved hole 11 in the center. The inner side of the temperature control sensor plug 1 has an annular cover edge 13 with a main body limiting groove 12.

[0038] The anti-misassembly handheld device 4 includes: a handheld body 41 and a contour-following temperature control head 42;

[0039] The handheld body 41 adopts a cuboid structure. The width of the handheld body 41 is adapted to the length between the sliding grooves 31 on both sides of the sensor bracket 3. The thickness of the handheld body 41 is adapted to the width of the sliding grooves 31. Moreover, the width of the handheld body 41 is greater than the diameter of the annular cover edge 13. The thickness of the handheld body 41 is adapted to the width of the body limiting slot 12.

[0040] The contoured temperature control head 42 is located at the end of the handheld body 41. The contoured temperature control head 42 can be inserted into the temperature control head reserved hole 11 to limit the position of the temperature control sensor plug 1 and the anti-misinstallation handheld device 4. The handheld body 41 is inserted into the main body limiting slot 12 to limit the angle between the temperature control sensor plug 1 and the anti-misinstallation handheld device 4.

[0041] When the user holds the handheld body 41 to install the temperature control sensor cover 1 on the inside of the instrument panel lower guard plate 2, the handheld body 41 is inserted into the slide groove 31 to limit the position and angle of the temperature control sensor cover 1 and the sensor bracket 3.

[0042] In this embodiment, the structural adaptation between the handheld main body 41 and the sliding grooves 31 on both sides of the sensor bracket 3 and the main body limiting groove 12 on the temperature control sensor plug 1, as well as the structural adaptation between the contoured temperature control head 42 and the reserved hole 11 of the temperature control head, effectively achieves the angle prevention of incorrect installation when the temperature control sensor plug 1 is installed on the lower guard plate 2 of the instrument panel. The structure is simple, easy to use, and low in cost.

[0043] like Figure 4 As shown, specifically, during the use of the anti-misinstallation handheld device 4, the sensor bracket 3 is first pre-installed on the lower panel 2 of the instrument panel, and then the temperature control sensor cover 1 is assembled onto the anti-misinstallation handheld device 4. Then, the installer holds the anti-misinstallation handheld device 4 to install the temperature control sensor cover 1 onto the lower panel 2 of the instrument panel. As the temperature control sensor cover 1 is assembled in place, the anti-misinstallation handheld device 4 is pushed out to complete the installation of the temperature control sensor cover 1.

[0044] In this process, the positioning of the temperature control sensor plug 1 and the anti-misinstallation handheld device 4 is limited by the structural adaptation of the conformal temperature control head 42 and the pre-drilled hole 11 of the temperature control head, and the handheld body 41 and the main body limiting slot 12. The positioning of the temperature control sensor plug 1 relative to the sensor bracket 3 is limited by the structural adaptation of the handheld body 41 and the sliding groove 31. That is to say, by pre-designing the sliding grooves 31 on both sides of the sensor bracket 3 and the main body limiting slot 12, the handheld body 41, the temperature control sensor plug 1 and the sensor bracket 3 can achieve the above-mentioned limiting method, thereby realizing the anti-misinstallation.

[0045] Moreover, since the width of the handheld body 41 is greater than the diameter of the annular cover edge 13, the handheld body 41 cannot be inserted into the annular cover edge 13 as a whole. It can only be assembled with the temperature control sensor plug 1 through the body limiting slot 12, which can achieve the limitation of the assembly angle.

[0046] like Figure 1 As shown, in the above embodiment, preferably, the anti-misassembly handheld device 4 further includes a positioning boss 43, which is disposed at the same end of the handheld body 41 as the contour temperature control head 42.

[0047] The inner side of the temperature control sensor plug 1 is provided with a positioning groove 14. The positioning boss 43 and the positioning groove 14 adopt a conformal design. The positioning groove 14 is positioned so that when the handheld body 41 is inserted into the main body limiting slot 12, the positioning boss 43 can be inserted into the positioning groove 14. The single-sided gap between the positioning boss 43 and the positioning groove 14 is 0.1 to 0.3 mm. The positioning boss 43 is inserted into the positioning groove 14 to realize the position limitation of the temperature control sensor plug 1 and the anti-misinstallation handheld device 4.

[0048] In this embodiment, based on the initial positioning of the handheld body 41 and the main body limiting slot 12, the positional limitation of the positioning boss 43 and the positioning groove 14 can further improve the assembly accuracy between the temperature control sensor plug 1 and the anti-misassembly handheld device 4, and reduce the shaking of the temperature control sensor plug 1 relative to the anti-misassembly handheld device 4. The single-sided gap between the positioning boss 43 and the positioning groove 14 is preferably 0.2 mm, which can effectively limit the plug while ensuring rapid pre-assembly of the plug and the tool, and prevent the plug from shifting before assembly.

[0049] In the above embodiment, preferably, the positional relationship between the contoured temperature control head 42 and the positioning boss 43 is the same as the positional relationship between the temperature control head reserved hole 11 and the positioning groove 14. The temperature control sensor plug 1 can be positioned and installed on the anti-misinstallation handheld device 4 through the positioning groove 14, and at the same time, the contoured temperature control head 42 can be inserted into the temperature control head reserved hole 11.

[0050] In this embodiment, the same positional relationship can effectively limit the angle of the assembly of the temperature control sensor plug 1 relative to the anti-misassembly handheld device 4, ensuring that there will be no errors in the assembly between the two.

[0051] In the above embodiment, preferably, when the temperature control sensor plug 1 is installed on the anti-misinstallation handheld device 4, the height of the profiled temperature control head protrudes at least 2 mm beyond the pre-drilled hole 11 of the temperature control head, so that after installation, the anti-misinstallation handheld device 4 can be detached from the temperature control sensor plug 1 by pressing the protruding profiled temperature control head 42 in the opposite direction.

[0052] like Figure 5As shown, in the above embodiment, preferably, a plug mounting hole 21 is provided on the lower instrument panel 2. When the user installs the temperature control sensor plug 1 on the inner side of the lower instrument panel 2 by holding the handheld body 41, the temperature control sensor plug 1 is located in the plug mounting hole 21. At the same time, the contoured temperature control head can protrude from the surface of the lower instrument panel 2, providing a convenient force point for thumb pressing. After installation, the anti-misinstallation handheld device 4 can be detached from the rear side of the lower instrument panel 2 by pressing the protruding contoured temperature control head 42 in the opposite direction, without affecting subsequent assembly.

[0053] In the above embodiment, preferably, the cuboid edge of the handheld body 41 is provided with a limiting guide rib 44. The overall size of the limiting guide rib 44 is adapted to the slide groove 31 of the sensor bracket 3. During the insertion of the handheld body 41 along the slide groove 31, the single-sided gap between the limiting guide rib 44 and the slide groove 31 is 0.1 to 0.3 mm. The slide groove 31 limits the position of the limiting guide rib 44 in the direction perpendicular to the insertion direction.

[0054] In this embodiment, the handheld body 41 can achieve basic position and angle limitation relative to the slide groove 31, ensuring that the installation direction will not be incorrect on a large scale. Furthermore, through the setting of the limiting guide rib 44, the conformal structure, and the 0.1–0.3 mm single-sided gap, it is possible to ensure smooth assembly of the tool and the bracket while precisely limiting the tool itself, ensuring correct assembly direction. The single-sided gap between the limiting guide rib 44 and the slide groove 31 is preferably 0.2 mm.

[0055] In the above embodiment, preferably, when the contoured temperature control head 42 is inserted into the temperature control head reserved hole 11, the single-sided gap between the contoured temperature control head 42 and the temperature control head reserved hole 11 is 0.1 to 0.3 mm. The single-sided gap of this assembly structure can not only achieve basic assembly limit, but also ensure that the tool can be smoothly removed from the back of the plug after pressing.

[0056] In the above embodiment, preferably, the two sides of each surface of the handheld body 41 corresponding to the slide groove 31 are provided with limiting guide ribs 44 along the direction of the slide groove 31. The design of providing limiting guide ribs 44 on both sides can improve the stability during the relative sliding process.

[0057] like Figure 6As shown, in the above embodiment, preferably, a fixing buckle 15 is provided on the edge 13 of the annular cover. The fixing buckle 15 is used to fix the temperature control sensor plug 1 to the inner side of the lower instrument panel 2. The fixing buckle 15 is positioned perpendicular to the slotting direction of the main body limiting slot 12. Thus, when the temperature control sensor plug 1 is assembled on the anti-misinstallation handheld device 4 under the limiting of the main body limiting slot 12, the fixing buckle 15 is perpendicular to the width direction of the handheld main body 41. When the user inserts the sensor bracket 3 into the slide groove 31 by holding the handheld main body 41, the fixing buckle 15 is also perpendicular to the direction of the line connecting the two slide grooves 31, which can effectively realize the angle limiting of the temperature control sensor plug 1 during installation and prevent misinstallation.

[0058] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
