[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor should belong to the protection scope of the present application.

As used herein, the articles "a", "an" or "the" preceding an element or item are intended to be construed to mean that there are one or more of such elements present unless the context clearly indicates otherwise.

[0035] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that the embodiments described herein are merely examples from among a great variety of embodiments that can be made.

[0036] The new energy vehicle has a power module, the power module includes a power supply and a space shell for placing the power supply, in the production process of the new energy vehicle, because the power supply of the vehicle needs to be electrically connected with external electrical appliances, therefore, the space shell of the power supply needs to be provided with a through hole for the wire harness to pass through, so as to realize the electrical connection between the power supply of the new energy vehicle and the external electrical appliances.

[0037] In addition, after the wire harness is installed on the power supply of the new energy vehicle, in order to ensure the safety, reliability and performance stability of the vehicle, and at the same time meet the requirements of industry standards and regulations, the power module of the vehicle needs to have air tightness, therefore, correspondingly, the power module is also provided with a wire harness connector, which can not only install the wire harness, but also seal the gap between the wire harness and the through hole of the space shell, so that the power module has air tightness to meet the needs of the vehicle.

[0038] However, due to the existing wire harness installation technology, the power module cannot obtain air tightness to meet the detection needs of the vehicle after the wire harness is installed, thereby causing the wire harness installation work of the power module to be unqualified, which needs to be reworked, or even scrapped, not only delaying the work progress, but also delaying the yield of the product, and affecting the work efficiency of the new energy vehicle production line.

[0039] In order to facilitate understanding why the installation of the wire harness affects the air tightness of the power module during the installation process of the wire harness, the following will be further described. Figures 1-4

[0040] ​In the present application, the first direction Z, the second direction Y and the third direction X are arranged at an angle with each other, but for the purpose of illustration and understanding, the third direction X identified in each drawing is identified with reference to the length direction of the rack 100 in the subsequent drawings, the second direction Y identified in each drawing is identified with reference to the width direction of the rack 100, the first direction Z identified in each drawing is identified with reference to the height direction of the rack 100, and the directions identified in each drawing are kept uniform for the purpose of reference and understanding.

[0041] As can be seen from the drawings, the power module 2 comprises a shell 22 and a wire harness mounting member 23, wherein the wire harness mounting member 23 is provided with a plug-in part 23a and a sealing member 23b, the sealing member 23b is sleeved on the plug-in part 23a, the plug-in part 23a is used to plug the mounting through hole 22b of the shell 22, the plug-in through hole 23c of the plug-in part 23a communicates with the mounting through hole 22b of the shell 22, so that the power module 2 forms a wire harness 3 channel for the wire harness 3 to pass through. After the wire harness 3 is installed, in the ideal state of the wire harness 3 installation, the sealing member 23b seals the inner wall of the through hole 312 and the plug-in part 23a in the power module 2, the wire harness 3 passes through and fills the plug-in through hole 23c of the plug-in part 23a, so that the power module 2 after installing the wire harness 3 can have good air tightness.

[0042] In the existing wire harness 3 installation process, there are various manual operation modes of the user, for example, the first mode is to assemble the power module 2 first, plug the plug-in part 23a of the wire harness mounting member 23 into the mounting through hole 22b, so that the power module 2 forms a wire harness 3 channel, then move one end of the wire harness 3 through the wire harness 3 channel to the internal space of the shell 22 to connect the power supply 21; the second mode is that the user first plugs the wire harness 3 into the plug-in through hole 23c, then plugs the plug-in part 23a into the mounting through hole 22b, so that the sealing member 23b is sealingly connected between the plug-in part 23a and the hole wall of the mounting through hole 22b, at the same time, the end of the wire harness 3 passes through the mounting through hole 22b into the internal space of the shell 22 with the movement of the wire harness mounting member 23.

[0043] However, the existing harness 3 installation operation has a significant defect, which is that when installing the harness 3, due to the length of the harness 3, and the part of the harness 3 located in the external space of the shell 22 needs to be reserved enough length to ensure that the power module 2 can be connected to the external electrical appliance, therefore, when the user does not hold the harness 3, or holds the harness 3 in an undesirable position, the part of the harness 3 located outside the power module 2 will bend downward under its own weight, and since the harness 3 has a part located in the insertion hole 23c, the harness mounting 23 will be driven by the harness 3, so that the insertion part 23a will be offset relative to the installation hole 22b, and since the sealing member 23b is connected to the insertion part 23a, the sealing member 23b will be unevenly deformed due to the movement of the insertion part 23a, and thus, the sealing effect of the sealing member 23b on the gap space between the installation hole 22b and the insertion part 23a will be reduced, although in the subsequent process, the user will fix the harness mounting 23 to the shell 22 by other fixing members, but it will still affect the air tightness of the power module 2, resulting in that the power module 2 cannot pass the subsequent air tightness test, and the user needs to rework and reinstall the harness 3 after disassembling the power module 2.

[0044] In addition, in the process of assembling the power module 2 by the user, in some implementable ways, the user will screw the harness mounting 23 to the shell 22 by screws, so as to strengthen the connection strength between the harness mounting 23 and the shell 22. And in the process of further fixing the harness mounting 23 to the shell 22 by the user, once the user does not hold the harness mounting 23 in time when screwing the screw, or the holding force is not enough, the rotational friction force between the screw and the harness mounting 23 may cause the harness mounting 23 to rotate relative to the shell 22, that is, the harness mounting 23 rotates relative to the shell 22 along the circumference of the installation hole 22b in the installation hole 22b, so that the insertion hole moves relative to the installation hole 22b, that is, the insertion hole deviates from the qualified position of the harness 3 (the qualified position refers to the relative position of the insertion hole in the installation hole 22b after the power module 2 is installed, which meets the air tightness requirement), not only the sealing member 23b will be unevenly deformed due to uneven force, but also the harness 3 will not be able to fill the insertion hole due to the movement of the insertion hole position when the harness 3 is inserted, thereby causing the air tightness of the power module 2 to not meet the vehicle requirements.

[0045] Further, it needs to be explained that the reason why the plug-in hole deviates from the qualified position of the wire harness 3 and causes the wire harness 3 to be unable to fill the plug-in hole is that, in the power supply module 2, the installation position of the power supply 21 in the internal space of the shell 22 is fixed, so the end position of the wire harness 3 that needs to be connected to the power supply 21 is also fixed accordingly. Due to the fixed position of the installation hole 22b, the position of the wire harness mounting member 23 relative to the shell 22 is fixed in an ideal state. Therefore, after the wire harness 3 is installed, the wire harness 3 should be located at a fixed position relative to the shell 22. However, in the above-mentioned manner, the wire harness mounting member 23 rotates relative to the installation hole 22b. At this time, due to the position limitation of the end of the wire harness 3 connected to the power supply 21, the position of the wire harness 3 relative to the plug-in hole 23c changes accordingly. The hard contact between the wire harness 3 and the hole wall of the plug-in hole 23c causes the wire harness 3 to locally deform, and the deformation of the wire harness 3 is uneven. Therefore, the wire harness 3 cannot fill the plug-in hole 23c, which not only affects the overall air tightness of the power supply module 2 after the wire harness 3 is installed, but also affects the service life of the wire harness 3 and the installation difficulty of the wire harness 3.

[0046] In the following, the embodiments of the present application will be further described with reference to the accompanying drawings. Figures 1-12 In the present application, the first direction Z, the second direction Y, and the third direction X are arranged at an angle with respect to each other. For the purpose of illustration and understanding, the third direction X is indicated as a length direction, the second direction Y is indicated as a width direction, and the first direction Z is indicated as a height direction in the drawings. The directions are indicated uniformly in the drawings for the purpose of reference and understanding. However, in the present application, as long as the directions are indicated uniformly, the directions can be indicated in any way.

[0047] In order to improve the above-mentioned problems, the plug-in hole can be first filled with a filler, and then the wire harness 3 can be inserted into the plug-in hole. Figures 4-6 The present application provides a positioning and mounting system 1000, which comprises a wire harness mounting member 23, a shell 22, and a positioning and mounting device 1 for pressing and fixing the wire harness mounting member 23 to the surface of a first mounting plate 22a. It should be understood that the positioning and mounting device 1 can be applied to position the wire harness mounting member on the surface of the first mounting plate 22a of the shell 22, but it can also be applied to other production and processing links that require positioning.

[0048] Please refer to the accompanying drawings again. Figures 4-12 In the installation and processing scene of the wire harness, the positioning and mounting device 1 is used to position the wire harness mounting member 23 on the first mounting plate 22a of the shell 22. The first mounting plate 22a refers to a component plate of the shell 22, which is provided with the above-mentioned installation hole 22b and is used to install at least one wire harness mounting member 23. The shell 22 has at least one first mounting plate 22a.

[0049] The positioning installation device 1 comprises a frame 100, the frame 100 comprises a base assembly 110, a guide assembly 120 and a mounting seat assembly 130, the base assembly 110 is used to position the operation position, or is in contact with the storage surface, to support other component structures and other connecting structures, the guide assembly 120 is used to guide the movement of the related structures of the positioning installation device 1, so that the related structures can be moved to the target position along the direction of the rod body of the guide assembly 120, and the mounting seat assembly 130 is used to provide the mounting position, so as to connect other structures of the positioning installation device 1 to the frame 100.

[0050] Wherein, the guide assembly 120 extends along the first direction Z to guide the related structures to move along the first direction Z, and the base assembly 110 and the mounting seat assembly 130 are arranged on opposite sides of the guide assembly 120 to form a space required for the related structures to move along the first direction Z, and the base assembly 110 and the mounting seat assembly 130 do not interfere with the related structures during the movement of the related structures along the first direction Z.

[0051] The positioning installation device 1 further comprises an adjusting assembly 200, the adjusting assembly 200 is rotationally connected to the mounting seat assembly 130, and has a first position (see Figure 5 ) and a second position (see Figure 6 ) relative to the mounting seat assembly 130, and the positioning installation device 1 can adjust the relative working state thereof by adjusting the position of the adjusting assembly 200 relative to the mounting seat assembly 130.

[0052] The positioning installation device 1 further comprises a positioning assembly 300, the positioning assembly 300 is slidably connected to the guide assembly 120, and the positioning assembly 300 is connected to the adjusting assembly 200 and reciprocally moves along the first direction Z with the rotation of the adjusting assembly 200, that is, the adjusting assembly 200 is used to drive the positioning assembly 300 to reciprocally move along the first direction Z of the guide assembly 120. Along the first direction Z, when the adjusting assembly 200 is located at the first position, the positioning assembly 300 is in an open state, and when the adjusting assembly 200 is located at the second position, the positioning assembly 300 is in a compression state.

[0053] In other words, when the adjusting assembly 200 moves, the positioning assembly 300 is driven to move and moves along the first direction Z, so that the adjusting assembly 200 can adjust the distance between the positioning assembly 300 and the base assembly, that is, when the adjusting assembly 200 is located at the first position, the positioning assembly 300 is located at a first distance from the base assembly 110, and when the adjusting assembly 200 is located at the second position, the positioning assembly 300 is located at a second distance from the base assembly 110, wherein the first distance is less than the second distance.

[0054] Thus, the positioning and mounting device 1 can position and press the wire harness mounting member 23 against the surface of the first mounting plate 22a. In the pressing state of the positioning and mounting device 1, the wire harness mounting member 23 is pressed against the surface of the first mounting plate 22a by the positioning assembly 300 of the positioning and mounting device 1. The positioning and mounting device 1 exerts sufficient force on the wire harness mounting member 23 to enable the wire harness mounting member 23 to be stably positioned on the surface of the first mounting plate 22a. Thus, neither the pressure exerted on the wire harness mounting member 23 by the wire harness 3 nor the rotational friction between the wire harness mounting member 23 and the screws used to attach the wire harness mounting member 23 to the case 22 (or the first mounting plate 22a) can cause the wire harness mounting member 23 to move relative to the first mounting plate 22a.

[0055] Thus, the sealing member 23b can be fixed relative to the first mounting plate 22a during the installation of the wire harness 3. The user can position and press the wire harness mounting member 23 against the surface of the first mounting plate 22a by the positioning and mounting device 1 during the installation of the wire harness 3. The sealing member 23b can be kept in sealing connection between the insertion portion and the wall of the mounting through hole 22b. Then, the user can perform the connection operation (e.g., screwing) of the wire harness mounting member 23. Thus, the sealing member 23b can not be deformed due to uneven force during the installation of the wire harness 3. The wire harness mounting member 23 can not move relative to the first mounting plate 22a due to the friction between the fixing member and the wire harness mounting member 23. Thus, after the installation of the wire harness 3 is completed, the positioning and mounting device 1 can be adjusted to the open state and removed from the power module 2. Since the wire harness mounting member 23 is fixed to the first mounting plate 22a by the fixing member, the wire harness mounting member 23 can not move relative to the first mounting plate 22a due to the pressure exerted by the wire harness 3. Thus, the power module 2 can have the required air tightness after the installation of the wire harness 3 is completed.

[0056] In the present application, the positioning and mounting device 1 can adaptively participate in the installation operation process of the wire harness 3 through the change of its own operation state. When the user needs to perform the wire harness 3 installation operation, the user can fix and position the wire harness mounting piece 23 through the positioning and mounting device 1, so that after the wire harness mounting piece 23 is connected to the first mounting plate 22a of the casing 22, the sealing clamp can seal and fill the gap between the insertion part and the mounting through hole 22b, and in the process of installing the wire harness 3, the wire harness mounting piece 23 will not move relative to the first mounting plate 22a due to the factors such as the drooping action of the wire harness 3, the friction action of other structures, the external force action of the user, etc. Therefore, the position of the insertion through hole 23c relative to the mounting through hole 22b and the position of the sealing piece 23b relative to the first mounting plate 22a are fixed. When the installation of the wire harness 3 is completed, the wire harness mounting piece 23 is fixed to the first mounting plate 22a by the fixing piece, and the force between the wire harness mounting piece 23 and the first mounting plate 22a due to the fixing piece is sufficient to resist the force applied to the wire harness mounting piece 23 by the wire harness 3. Therefore, the wire harness mounting piece 23 can maintain its connection state with the first mounting plate 22a, that is, the sealing piece 23b will not move due to external interference, thereby maintaining the air tightness of the power module 2 after the wire harness 3 is installed.

[0057] It should be understood that the aforementioned positioning and mounting system 1000 refers to an operation system, which is a virtual integrated system, and its purpose is to illustrate the combined use state of the positioning and mounting device 1 and the power module 2. In actual production operation, the positioning and mounting system 1000 can be formed by partial structures of the power module 2 or by all structures of the power module 2.

[0058] Further, the base assembly 110 is provided with a positioning groove 113 extending along the third direction X (the third direction X is arranged at an angle with the plane formed by the first direction Z and the second direction Y), and the first mounting plate 22a is inserted into the positioning groove 113. Thus, when the user uses the positioning and mounting device 1, due to the opening direction of the groove body of the positioning groove 113, the groove side wall of the positioning groove 113 can abut against the first mounting plate 22a. Further, the positioning assembly 300 can move towards the base assembly 110 under the linkage action of the adjusting assembly 200, so as to press the wire harness mounting piece 23 against the surface of the first mounting plate 22a. Correspondingly, the force applied by the wire harness mounting piece 23 to the positioning assembly 300 has a tendency to move the positioning assembly 300 away from the base assembly 110. At this time, the abutting action between the groove side wall of the positioning groove 113 and the first mounting plate 22a can balance the force applied by the wire harness mounting piece 23 to the positioning assembly 300. Thus, when the positioning and mounting device 1 is in the pressing state, the base assembly 110 can be positioned and connected to the first mounting plate 22a due to the positioning groove 113, and the positioning and mounting device 1 can be positioned and connected to the casing 22 due to the positioning and connection of the base assembly 110.

[0059] When the positioning mounting device 1 is in the closed state, the adjusting assembly 200 is in the first position, the first mounting plate 22a is inserted into the positioning groove 113, and the positioning assembly 300 abuts against the wiring harness mounting member 23 on the surface of the first mounting plate 22a. When the positioning mounting device 1 is in the open state, the adjusting assembly 200 is in the second position, and the user can move the positioning mounting device 1 so that the first mounting plate 22a is inserted into the positioning groove 113.

[0060] Further, referring to Figure 9 The base assembly 110 can be composed of a plurality of structures such as the backing plate 111 and the bottom plate 112, so as to reduce the cost of the mold for integrally forming the base assembly 110. The positioning groove 113 can be formed by the mutual structure (such as the position, shape, and other features) between the backing plate 111 and the bottom plate 112.

[0061] Please refer to Figures 7 to 12 In some embodiments, the adjusting assembly 200 further comprises an adjusting handle 210, which is rotationally connected to the mounting seat assembly 130. The user can adjust the position of the adjusting assembly 200 relative to the mounting seat assembly 130 by rotating the adjusting handle 210. When the adjusting assembly 200 is in the first position, the adjusting handle 210 is rotated to the first adjusting position relative to the mounting seat assembly 130. When the adjusting assembly 200 is in the second position, the adjusting handle 210 is rotated to the second adjusting position relative to the mounting seat assembly 130. It should be understood that the first position and the second position refer to the position characteristics of the adjusting assembly 200 relative to the mounting seat assembly 130, and the first adjusting position and the second adjusting position refer to the position characteristics of the adjusting handle 210 relative to the mounting seat assembly 130.

[0062] The adjusting assembly 200 further comprises a linkage 220, one end of which is rotationally connected to one end of the adjusting handle 210, and the other end is connected to the positioning assembly 300. When the adjusting handle 210 is rotated relative to the mounting seat assembly 130, the linkage 220 drives the positioning assembly 300 to move along the first direction Z towards or away from the base assembly 110 together with the adjusting handle 210. In this way, the linkage 220 can synchronize the movement state of the adjusting assembly 200 and the positioning assembly 300. The user can synchronize the movement of the positioning assembly 300 by operating the adjusting handle 210, thereby increasing the timeliness and synchronization of the state switching of the positioning assembly 300 and the positioning mounting device 1.

[0063] The separate arrangement of the positioning assembly 300 and the linkage 220 not only increases the convenience of assembling the positioning mounting device 1, but also reduces the action constraint between the positioning assembly 300 and the adjusting assembly 200 through structural decoupling of the positioning assembly 300 and the linkage 220. Therefore, the arrangement of the linkage 220 increases the convenience between the positioning assembly 300 and the adjusting assembly 200.

[0064] In this embodiment, the user can adjust the position of the positioning component 300 by moving the adjustment handle 210. By providing the adjustment handle 210 to the adjustment component 200, the convenience for the user when using the positioning installation device 1 is increased. The user can adjust the adjustment component 200 by moving the adjustment handle 210. The adjustment component 200 moves the linkage 220, thereby moving the positioning component 300.

[0065] Please refer to Figure 8 and Figure 9 Furthermore, the adjustment handle includes a grip portion 211 and a handle connecting portion 212 connected together. The grip portion 211 and the handle connecting portion 212 have an included angle α, which is less than or greater than 0°. When the user moves the grip portion 211, the handle connecting portion 212 can move accordingly.

[0066] It should be noted that, because the adjustment handle 210 can be positioned relative to the mounting base assembly 130 along... Figure 12 The rotation direction r is shown to reciprocate. To help the reader understand the position of the adjustment handle 210 relative to the mounting base, when the adjustment handle 210 rotates clockwise relative to the mounting base assembly 130 in the rotation direction r (i.e., the adjustment assembly 200 rotates from the first adjustment position to the second adjustment position), the included angle α between the grip portion 211 and the handle connecting portion 212 is set to be greater than 0. When the adjustment handle 210 rotates counterclockwise relative to the mounting base assembly 130 in the rotation direction r (i.e., the adjustment assembly 200 rotates from the second adjustment position to the first adjustment position), the included angle α between the grip portion 211 and the handle connecting portion 212 is set to be less than 0. Thus, the position of the adjustment handle 210 relative to the mounting base assembly 130 is set with different positive and negative values ​​for the included angle α.

[0067] The handle connection portion 212 has a bent connection end 2120 and a handle linkage end 2121 disposed opposite to each other. The handle linkage end 2121 is rotatably connected to the linkage member 220, and the bent connection end 2120 is connected to the grip portion 211. When the user moves the grip portion 211, the bent connection end 2120 and the handle linkage end 2121 move, and the handle linkage end 2121 rotates relative to the linkage member 220 to counteract the torque generated between the adjustment handle 210 and the linkage member 220 when the adjustment handle 210 rotates relative to the mounting base assembly 130.

[0068] The adjusting assembly further comprises at least one support member 230 having oppositely arranged support positioning end 2310 and support linkage end 2311, the support positioning end 2310 is rotationally connected to the mounting base assembly 130 to counteract the torque effect generated when the support member 230 rotates relative to the mounting base assembly 130, and the support linkage end 2311 is rotationally connected to the bent connection end 2120 to counteract the torque effect generated when the adjusting handle 210 rotates relative to the support member 230.

[0069] The positioning mounting device 1 is switched from an open state (as shown in Figure 6 、 Figure 10 ) to a compression state (as shown in Figure 5 、 Figure 7 ), and the adjusting handle 210 is rotated from the first adjusting position to the second adjusting position by an angle β, where 180°≤β<360°.

[0070] When the positioning mounting device 1 is in the open state (as shown in Figure 10 ) or the compression state (as shown in Figure 7 ), that is, when the adjusting handle 210 is in the first adjusting position and the second adjusting position, the support connecting portion 231 and the handle connecting portion 212 extend along the first direction Z, the hand holding portion 211 extends along the third direction X, and the linkage member 220, the support member 230, and the handle linkage end 2121 are all arranged in line along the first direction. In terms of connection, that is, the linkage member 220 is arranged in line with the handle linkage end 2121, the bent connection end 2120, the support positioning end 2310, and the support linkage end 2311.

[0071] Wherein, Figure 12 The state switching of the positioning mounting device 1 is schematically shown. It should be noted that, Figure 12 The adjusting assembly 200 and the positioning assembly 300 are shown in Figure 12 The solid line part of the adjusting assembly 200 and the positioning assembly 300 represents the position of the adjusting assembly 200 and the positioning assembly 300 relative to the rack 100 when the positioning mounting device 1 is in the compression state, and the dashed line part of the adjusting assembly 200 and the positioning assembly 300 represents the position of the adjusting assembly 200 and the positioning assembly 300 relative to the rack 100 when the positioning mounting device 1 is in the open state.

[0072] When the user adjusts and moves the adjusting assembly 200, the adjusting handle 210 can be reciprocally rotated relative to the mounting base assembly 130 along the rotation direction r in the figure, so as to correspondingly adjust the position of the positioning assembly 300 relative to the base assembly 110, so as to switch the positioning mounting device 1 to the compression state or the open state.

[0073] As can be seen from the foregoing, when the adjusting component 200 is in the first or second position relative to the mounting base component 130, the adjusting handle 210 is in the first or second adjusting position. Correspondingly, the positioning mounting device 1 is in a pressed or open state. Moreover, the adjusting handle 210 and the linkage component 220 are rotatably connected through the handle linkage end 2121 and the linkage component 220. The adjusting handle 210 and the support component 230 are rotatably connected through the bent connection end 2120 and the support linkage end 2311. The support component 230 and the mounting base component 130 are rotatably connected through the support positioning end 2310 and the mounting base component 130. Therefore, in the adjusting component 200, the specific rotatable connection points are: the handle linkage end 2121, the bent connection end 2120, the support linkage end 2311, and the support positioning end 2310.

[0074] When the positioning and mounting device 1 is in the pressing state (e.g.) Figure 7 When the positioning and mounting device 1 presses the wire harness mounting component 23, the force exerted by the wire harness mounting component 23 on the positioning component 300 extends along the first direction Z. At this time, due to the transmission effect of the linkage component 220, it is necessary to ensure that the forces between the structures of the adjustment component 200 are collinear and extend along the first direction Z in order to ensure that the adjustment component 200 stably presses the wire harness mounting component 23 onto the first mounting plate 22a. Therefore, the four connection positions of the handle linkage end 2121, the bending connection end 2120, the support linkage end 2311, and the support positioning end 2310 are collinearly arranged so that the constraint effect generated by the adjustment component 200 extends along the first direction Z, thereby stably fixing and pressing the wire harness mounting component 23 onto the first mounting plate 22a.

[0075] Furthermore, since the grip portion 211 and the handle connection portion 212 are set at an angle, when the user rotates the adjustment handle 210, the actual point of force application is at a certain distance from the handle connection portion 212. Therefore, the handle connection portion 212, especially the handle linkage end 2121, generates a certain torque. The user can use a smaller force to move the linkage member 220 that is rotated and connected to the handle linkage end 2121. Therefore, this design can reduce the user's effort to a certain extent, allowing the user to use the positioning installation device 1 better and more conveniently.

[0076] In addition, since the hand holding part 211 and the handle connecting part 212 are arranged at an included angle, the bending connecting end 2120 rotates the supporting positioning end 2311, and the supporting positioning end 2311 rotates the mounting seat assembly 130. Thus, when the positioning assembly 300 moves in the first direction Z, the rotation connection between the multiple points can offset the torque effect between the adjusting handle 210, the supporting member 230, the supporting member 230 and the mounting seat assembly 130, and the adjusting handle 210 and the linkage 220. Therefore, the rotation connection between the supporting positioning end 2310 and the mounting seat assembly 130 can ensure that the bending connecting end 2120 and the supporting linkage end 2311 move relative to the linkage 220 in the third direction X. The bending connecting end 2120 and the supporting linkage end 2311 can move relative to the linkage 220 in the third direction X, avoid the handle linkage end 2121, and enable the handle linkage end 2121 to move in the first direction Z. Thus, the positioning assembly 300 can move back and forth in the first direction Z along with the adjusting assembly 200.

[0077] For further reference, Figure 8 , Figure 9 and Figure 11 , further, the adjusting assembly 200 further comprises a limiting member 232, the limiting member 232 is connected between the two supporting members 230, and the limiting member 232 and the two supporting members 230 jointly form a limiting space. During the process of rotating the adjusting handle 210 from the first adjusting position to the second adjusting position, the handle linkage end 2121 moves towards the limiting space. When the adjusting handle 210 is located at the second adjusting position, the handle linkage end 2121 is located in the limiting space in the first direction Z, and the handle linkage end 2121 abuts against the limiting member 232.

[0078] Thus, when the handle linkage end 2121 abuts against the limiting member 232, it means that the positioning mounting device 1 has reached the pressing state, and the wire harness mounting member 23 has been stably pressed on the first mounting surface. At this time, the positioning mounting device 1 can remind the user that the adjusting handle 210 has been moved to the position. The abutting effect of the handle connecting part 212 and the limiting member 232 can also constrain the movement of the adjusting handle 210 to avoid the user from excessively moving the adjusting handle 210 and damaging the wire harness mounting member 23 and / or the first mounting plate 22a.

[0079] For further reference, Figure 8 , Figure 9 and Figure 11In some embodiments, the mounting base assembly 130 includes a handle base 240 and a mounting base 132, arranged sequentially along a first direction Z. The handle base 240 is disposed on the mounting base 132 and has a first through hole 241. The mounting base 132 has a second through hole 131, and the first through hole 241 is aligned with and communicates with the second through hole 131, in order to eliminate structural interference between the linkage 220 and the mounting base 132 and the handle base 240 when the linkage 220 moves with the adjustment assembly 200.

[0080] The handle connection 212 of the adjustment handle 210 is rotatably connected to the handle base 240 via the support member 230. The linkage member 220 passes through the first through hole 241 and the second through hole 131 and moves back and forth along the hole direction of the first through hole 241 and the second through hole 131.

[0081] The handle base 240 provides a mounting position for the adjustment component 200 and indirectly connects the adjustment component 200 to the frame 100. Since the adjustment component 200 needs to move relative to the mounting base assembly 130, connecting the mounting base 132 via the handle base 240 and then connecting it to the frame 100 via the mounting base 132 not only satisfies the adjustment function of the adjustment component 200, but also avoids wear on the mounting base 132 due to the movement of the adjustment component 200 relative to the mounting base 132 when the adjustment component 200 is directly connected to the frame 100 via the mounting base 132, thus reducing the service life of the frame 100. Since the frame 100 is also connected to the positioning component 300, damage to the frame 100 has a significant impact on the use of the positioning mounting device 1. Therefore, by setting the handle base 240, the service life of the frame 100 can be improved and the positioning function of the positioning mounting device 1 can be maintained.

[0082] like Figures 7 to 12 As shown, the mounting base assembly 130 further includes a fastener 133, which is connected to the handle base 240. The mounting base 132 is sandwiched between the handle base 240 and the fastener 133. The fastener 133 is used to further fix the handle base 240 and the mounting base 132, thereby improving the overall structural stability of the mounting base assembly 130.

[0083] The fixing member 133 is provided with a third through hole 1331, which is aligned with and connected to the first through hole 241 and the second through hole 131 to form a through channel. The linkage member 220 passes through the through channel and moves back and forth along the channel direction of the through channel as the adjusting handle 210 rotates.

[0084] In some embodiments, the fixing member 133 is a screw cap, and the handle base 240 is provided with a threaded connection portion. When the mounting seat assembly 130 is assembled, the threaded connection portion of the handle base 240 at least partially penetrates the second through hole 131 of the mounting seat 132 and is connected to the fixing member 133, so that the fixing member 133 abuts against the surface of the mounting seat 132 away from the side where the adjusting assembly 200 is located.

[0085] Optionally, the handle base 240, the mounting seat 130, and the fixing member 133 are integrally formed by welding, and after being formed by welding, the three can form a penetration channel for the linkage member 220 to penetrate.

[0086] As shown in Figure 9 Further, the adjusting handle 210 further includes a protective layer 213 sleeved outside the gripping portion 211, which can reduce the abrasion of the gripping portion 211 and also reduce the discomfort of the user when holding the adjusting handle 210 by adjusting the material, shape, and other characteristics of the protective layer 213.

[0087] In some embodiments, the linkage member 220 further includes a first sub-linkage member 221 and a second sub-linkage member, and the second sub-linkage member has a body portion 222 and two fastening portions 223, and the two fastening portions 223 are respectively arranged at two ends of the body portion 222. One end of the first sub-linkage member 221 is rotationally connected to the adjusting handle 210, and the other end is connected to the fastening portion 223 of the second sub-linkage member.

[0088] The positioning assembly 300 includes a positioning base 310 provided with an avoidance notch 311 recessed along the second direction Y, and the body portion 222 is inserted into the avoidance notch 311, and the positioning base 310 is clamped between the two fastening portions 223.

[0089] In this way, the second sub-linkage member can be connected to the first sub-linkage member 221 through the fastening portion 223, and can also be clamped and connected to the positioning base 310 through the two fastening portions 223, so that the positioning assembly 300 is connected to the linkage member 220. When the adjusting handle 210 drives the linkage member 220 to move, the positioning assembly 300 can move with the linkage member 220 through the connection relationship between the positioning base 310 and the second sub-linkage member.

[0090] Referring to Figures 4 to 12 Optionally, the positioning and mounting device 1 further includes a moving handle 400 connected to the outer periphery of the rack 100, so as to facilitate the user to move the positioning and mounting device 1 to a target use position, thereby improving the moving convenience of the positioning and mounting device 1.

[0091] Referring to Figures 8 to 12Optionally, the guiding assembly 120 comprises at least one guide rod 121, and the positioning base 310 is provided with one or more connecting through holes 312 corresponding to the guide rod 121, and the guide rod 121 is arranged through the connecting through hole 312 to guide the movement of the positioning base 310. The positioning base 310 is slidingly connected to the guide rod 121, and one end of the linkage 220 is connected to the positioning base 310. When the adjusting handle 210 moves, the positioning base 310 moves back and forth along the first direction Z with the movement of the adjusting handle 210. The positioning assembly 310 further comprises an abutting piece 320 connected to the positioning base 310 and moving back and forth along the first direction Z with the positioning base 310. When the positioning mounting device 1 is in the pressing state, the abutting piece 320 abuts against the wire harness mounting piece 23 and the first mounting plate 22a.

[0092] When the guiding assembly 120 is provided with multiple guide rods 121 and the multiple guide rods 121 are arranged at intervals, the positioning assembly 300 is provided with multiple connecting through holes 312 corresponding to the guide rods 121, and one connecting through hole 312 is used to arrange at least one guide rod 121. In this way, the positioning assembly 300 is arranged with multiple guide rods 121 at the same time, which increases the connection between the positioning assembly 300 and the rack 100. When the positioning assembly 300 moves, the multiple guide rods 121 simultaneously restrict the movement of the positioning assembly 300 to avoid the positioning assembly 300 from swinging or rotating when moving along the first direction Z of the rack 100, thereby improving the positioning effect of the positioning mounting device 1.

[0093] For reference Figures 8 to 12 In some embodiments, the positioning assembly 300 comprises a positioning base 310 and an abutting piece 320. The positioning base 310 is connected to the adjusting assembly 200 and slidingly connected to the guiding assembly 120. When the adjusting assembly 200 moves, the positioning base 310 moves back and forth along the first direction Z with the movement of the adjusting assembly 200. The abutting piece 320 is connected to the positioning base 310 and moves back and forth along the first direction Z with the positioning base 310. When the adjusting assembly 200 is located at the first position, the abutting piece 320 abuts against the wire harness mounting piece 23 on the surface of the first mounting plate 22a, thereby realizing the positioning function of the positioning mounting device 1.

[0094] For reference Figure 8 , Figure 9 and Figure 12 In some embodiments, the abutting piece 320 is provided with an elastic end 321 located at the end of the abutting piece 320 towards the base assembly 110 and used to abut against the wire harness mounting piece 23 on the surface of the first mounting plate 22a. The elastic end 321 can reduce the hard contact between the abutting piece 320 and the wire harness mounting piece 23 by deforming itself, thereby reducing the possibility of the abutting piece 320 damaging the wire harness mounting piece 23.

[0095] It is mentioned that, in some embodiments, when the positioning installation device 1 is in the pressing state, the positioning assembly 300, for example, the base assembly 110, is at a first distance, where the first distance can refer to the distance between the positioning base 310 and the base assembly 110, or the distance between the end of the abutting piece 320 close to the base assembly 110 and the base assembly 110. It should be noted that due to the structural connection relationship between the adjusting assembly 200 and the positioning assembly 300, the first distance here is a fixed value limited by the linkage between the structures, therefore, the wire harness mounting piece 23 needs to maintain a fixed specification to ensure that when the positioning installation device 1 is in the pressing state, the wire harness mounting piece 23 can be just pressed on the surface of the first mounting plate 22a.

[0096] However, due to manufacturing errors between different wire harness mounting pieces 23, and users may use wire harness mounting pieces 23 of similar but different specifications for wire harness installation work for some reason, when the positioning installation device 1 is in the pressing state, the distance between the positioning assembly 300 and the wire harness mounting piece 23 changes. At this time, if the end of the abutting piece 320 is the elastic end 321, the elastic end 321 can compensate for the change in distance caused by the specification of the wire harness mounting piece 23 to a certain extent by deforming itself, thereby increasing the matching accommodation degree between the positioning installation device 1 and the wire harness mounting piece 23, and to a certain extent, the application range of the positioning installation device 1 is increased.

[0097] Further, the elastic end 321 can be integrally formed on the end of the abutting piece 320 by an elastic material, or can be formed by installing a spring or the like on the end of the abutting piece 320, or can be formed by sleeving an elastic sleeve on the end of the abutting piece 320. The material of the elastic sleeve can be rubber, silicone or other elastic materials, which are not restricted here as long as they meet the use conditions.

[0098] For reference Figure 8 , Figure 9 and Figure 11 Optionally, the positioning assembly 300 includes a plurality of abutting pieces 320, and the plurality of abutting pieces 320 are connected to the positioning base 310 in a spaced manner. In the positioning installation system 1000, when the positioning installation device 1 is in the pressing state, the abutting ends of at least two abutting pieces 320 abut against the wire harness mounting piece 23 to the surface of the first mounting plate 22a. In this way, the plurality of abutting pieces 320 can jointly abut at different positions of the positioning assembly 300 to increase the abutting area of the positioning assembly 300 to the wire harness mounting piece 23 and improve the positioning effect of the positioning assembly 300 to the wire harness mounting piece 23.

[0099] Among them, the abutting end of the abutting piece 320 can be the elastic end 321 mentioned in the foregoing embodiments, or can be an end with other physical properties, such as a rigid end, a ductile end, etc.

[0102] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
