[0039] Based on the problem that the existing receiving structure of automobile parts cannot be installed and maintained due to mutual obstruction of parts and small operating space for tools, the present application provides an installation tool and a receiving device. The installation tool can pass through the receiving device to assemble the receiving device.

[0040] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an installation tool 10 is provided for assembling a receiving device 20. The installation tool 10 may include a fastening assembly 11, a driving connector 13 and a transmission assembly 12. The fastening assembly 11 has a fastening hole 110, and the fastening hole 110 is used to limit the engagement with a fixing bolt 23 or a fixing nut 24 of the receiving device 20. The driving connector 13 is used to connect a power tool. The transmission assembly 12 includes a first transmission member 121 and a second transmission member 122, the first transmission member 121 includes a first transmission shaft 1211 and a first bevel gear portion 1212 fixedly connected to the first transmission shaft 1211, the first transmission shaft 1211 is used to pass through the tool through hole 2121 of the receiving device 20, the second transmission member 122 includes a second transmission shaft 1221 and a second bevel gear portion 1222 fixedly connected to the second transmission shaft 1221, the second transmission shaft 1221 is fixedly connected to the fastening assembly 11, and the first bevel gear portion 1212 is engaged with the second bevel gear portion 1222; the first transmission shaft 1211 is detachably connected to the drive connecting member 13, and when the power tool drives the drive connecting member 13 to rotate, the transmission assembly 12 is driven to rotate the fastening assembly 11.

[0041] When the installation tool 10 is used for assembly, the drive connector 13 can be first removed from the first transmission shaft 1211, the fastening assembly 11 and the transmission assembly 12 can be placed in the receiving device 20, the fixing bolt 23 or the fixing nut 24 of the receiving device 20 can be installed in the fastening hole 110 of the fastening assembly 11, and then the first transmission shaft 1211 is passed through the tool through hole 2121 of the receiving device 20 to be driven and connected with the drive connector 13. In this way, when the drive connector 13 is driven to rotate by the power tool, the drive connector 13 drives the first transmission shaft 1211 to rotate synchronously, and the first transmission shaft 1211 drives the second transmission shaft 1221 to rotate through the cooperation of the first bevel gear portion 1212 and the second bevel gear portion 1222, and the second transmission shaft 1221 drives the fastening assembly 11 to rotate, thereby locking or unlocking the fixing bolt 23 or the fixing nut 24, thereby realizing the assembly or disassembly of the receiving device 20.

[0042] It is understandable that the first transmission shaft 1211 can be connected to the drive connector 13 from the outside of the receiving device 20, so that the power tool can avoid the shielding of the receiving device 20 to output torque to the installation tool 10, and the first bevel gear portion 1212 and the second bevel gear portion 1222 cooperate to change the torque direction of the transmission assembly 12, so that the drive connector 13 can transmit torque from the side of the fixing bolt 23 or the fixing nut 24. In this way, the installation tool 10 can avoid the interference of parts and components, directly enter the narrow space of the receiving device 20 of the car, and directly operate the fixing bolt 23 or the fixing nut 24 without changing the design of the receiving device 20.

[0043] It is worth noting that the first transmission shaft 1211 can also pass through the gaps between the components of the receiving device 20 to enter the receiving device 20 without opening a tool through hole 2121 on the receiving device 20 .

[0044] More specifically, if Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, the driving connection member 13 includes a driving connection shaft 131 and a limiting connection shaft 132 connected to the driving connection shaft 131, the driving connection shaft 131 is used to drive and connect with the power tool, the limiting connection shaft 132 is provided with a limiting groove 1320, the first transmission shaft 1211 includes a transmission shaft body 12111 and a limiting portion 12112 connected to the transmission shaft body 12111, the limiting portion 12112 is inserted into the limiting groove 1320, so that the driving connection shaft 131 is fixedly connected to the first transmission shaft 1211. In this way, through the limiting cooperation of the limiting groove 1320 and the limiting portion 12112, the driving connection shaft 131 and the transmission shaft body 12111 can keep synchronous rotation, so that the power tool can transmit torque to the first transmission member 121 through the driving connection shaft 131.

[0045] Optionally, in some embodiments, there may be multiple choices for the number and shape of the limiting groove 1320 and the limiting portion 12112. When the number of the limiting groove 1320 is one, the shape of the limiting groove 1320 is non-circular to avoid relative rotation when the limiting portion 12112 is inserted into the limiting groove 1320; when the number of the limiting groove 1320 exceeds one, the shape of the limiting groove 1320 is not restricted.

[0046] Preferably, if Figure 6 and Figure 7 As shown, in one embodiment, the limiting connecting shaft 132 is provided with two limiting grooves 1320, and the shapes of the two limiting grooves 1320 are both bow-shaped. The first transmission shaft 1211 includes two limiting portions 12112 connected to the transmission shaft body 12111, and the cross-sectional shapes of the two limiting portions 12112 are both bow-shaped. The limiting portions 12112 are respectively inserted into the limiting grooves 1320.

[0047] Alternatively, if Figure 7 As shown, in one embodiment, the drive connection shaft 131 has a plurality of force-bearing surfaces 1310, which are arranged circumferentially around the drive connection shaft 131, and the force-bearing surfaces 1310 are used to receive the driving force of the power tool so that the drive connection member 13 is driven to rotate. The arrangement structure of the force-bearing surfaces 1310 can be selected according to the structure of the output end of the power tool, for example, arranged in a quadrilateral, hexagonal structure, etc.

[0048] In particular, in one embodiment, the angle between the intersection axes of the first bevel gear portion 1212 and the second bevel gear portion 1222 is 90°, that is, after the first bevel gear portion 1212 and the second bevel gear portion 1222 are meshed, the angle between the first transmission shaft 1211 and the second transmission shaft 1221 is 90°.

[0049] Furthermore, if Figure 5 As shown, in one embodiment, the fastening assembly 11 includes a fastener 111, a base 112 and an elastic member 113, the fastening hole 110 is opened in the fastener 111, the second transmission shaft 1221 is fixedly connected to the fastener 111, the fastener 111 is slidably connected to the base 112, and the elastic member 113 is arranged between the fastener 111 and the base 112, and is used to press the fastener 111. In this way, the fastener 111 is pressed by the elastic member 113, so that when the fastener 111 is locked, the fixing bolt 23 or the fixing nut 24 can be pressed, so that the fixing bolt 23 or the fixing nut 24 can be pressed.

[0050] Alternatively, if Fig. 9 As shown, in some embodiments, the fastening hole 110 can be implemented as a hexagonal hole or a plum blossom hole.

[0051] Preferably, if Figure 5 , Figure 8 and Fig. 9 As shown, in one embodiment, the base 112 includes an annular cylinder wall 1121, a top wall 1122 and a bottom wall 1123, the annular cylinder wall 1121 is connected to the top wall 1122 and the bottom wall 1123, the fastener 111 is slidably disposed in the annular cylinder wall 1121, and the elastic member 113 is a compression spring, which is disposed between the top wall 1122 and the fastener 111. In this arrangement, the compression spring applies a spring force to the fastener 111, so that the fastener 111 can compress the fixing bolt 23 or the fixing nut 24.

[0052] Preferably, if Figure 8 As shown, in one embodiment, the top wall 1122 has a transmission shaft through hole 11220, and the second transmission shaft 1221 penetrates into the annular barrel wall 1121 through the transmission shaft through hole 11220. In other words, the second transmission shaft 1221 passes through the transmission shaft through hole 11220 and is connected to the fastener 111 located in the annular barrel wall. In this way, the second transmission shaft 1221 is restricted by the transmission shaft through hole 11220, the shaking of the second transmission shaft 1221 is reduced, and the stability of the second transmission shaft 1221 is increased.

[0053] Preferably, if Figure 8 As shown, in one embodiment, the bottom wall 1123 is provided with an avoidance hole 11230, and the size of the avoidance hole 11230 is larger than the size of the fastening hole 110. In this way, the avoidance hole 11230 can allow the fixing bolt 23 or the fixing nut 24 to pass through and enter the fastening hole 110 to avoid interference with the bottom wall 1123.

[0054] Preferably, if Figure 8 and Fig. 9 As shown, in one embodiment, at least one slide groove 11210 is provided on the inner side of the annular cylinder wall 1121 and arranged along the axial direction of the annular cylinder wall 1121. The fastener 111 includes a fastening body 1111 and at least one slider portion 1112 protruding from the outer side of the fastening body 1111, and the slider portion 1112 is slidably arranged in the slide groove 11210. In this way, the slider portion 1112 cooperates with the slide groove 11210, which can make the fastener 111 slide more smoothly on the one hand, and on the other hand, the slider portion 1112 and the slide groove 11210 are limited so that the base 112 and the fastener 111 rotate synchronously.

[0055] More preferably, if Figure 8 and Fig. 9 As shown, in one embodiment, two slide grooves 11210 are provided on the inner side of the annular barrel wall, and the fastener 111 includes a pair of sliders 1112, and the sliders 1112 are convexly arranged on both sides of the fastening body 1111. Such a configuration can further strengthen the position limiting of the sliders 1112 and the slide grooves 11210, so that the base 112 and the fastener 111 can rotate more stably.

[0056] Furthermore, if Figure 2 and Figure 3As shown in the figure, the present application provides a receiving device 20, which can be assembled by the installation tool 10 described in any of the above. The receiving device 20 may include: a front window connecting member 21, a suspension connecting member 22, a fixing bolt 23, and a fixing nut 24.

The fixing nut 24 is connected to the fixing bolt 23 to fixedly connect the second fixing portion 213 and the suspension connecting member 22.

[0057] The receiving device 20 can be used to connect the body front window sheet metal and the vehicle suspension. The receiving device 20 can receive the fastening assembly 11 of the installation tool 10 through the U-shaped front window fixing member, and enable the transmission assembly 12 of the installation tool 10 to pass through the tool through hole 2121, so as to facilitate assembly and subsequent maintenance.
