[0007] To achieve the above and other related objectives, the present utility model provides an auxiliary fixture for installing a front-engine front-wheel-drive electric vehicle engine compartment bracket, including a clamping assembly and an adjustment assembly. The clamping assembly fixes the engine compartment bracket, and the adjustment assembly adjusts the position of the clamping assembly.

[0030] The following individual embodiments are only for illustration. Combinations can be made between individual embodiments, and it is not limited to the content shown in the following single embodiments.

[0031] Please refer to Figure 1, the present utility model provides an auxiliary fixture for installing a front-wheel drive electric vehicle engine compartment bracket. Similar to the existing process technology, the installation auxiliary fixture includes a clamping assembly 1 and an adjustment assembly 2. The clamping assembly 1 is used to fix the engine compartment bracket, and the adjustment assembly 2 adjusts the position of the clamping assembly 1, so as to achieve the function of adjusting the position of the engine compartment bracket. Different from the prior art, the adjustment assembly 2 includes a rotating shaft component 21, a power component 22 and a limiting component 23; the rotating shaft component 21 is fixedly connected to the clamping assembly 1, and the power component 22 drives the rotating shaft component 21 to rotate circumferentially; this design enables the operator to drive the power component 22 to drive the rotating shaft component 21 to rotate according to the specific installation components, that is, to drive the engine compartment bracket to rotate to a position suitable for operation and installation. Compared with the prior art of adjusting the entire fixture, the operator is more labor-saving.

[0032] As Figure 2 shown, the limiting component 23 includes a turntable 231 and a plug shaft 232. The turntable 231 rotates simultaneously with the rotating shaft component 21; a plurality of limiting holes 233 are formed on the turntable 231, and the plurality of limiting holes 233 are arranged along the circumferential direction of the turntable 231; the plug shaft 232 is movably installed, and the plug shaft 232 cooperates with any one of the limiting holes 233, and the clamping assembly 1 is fixed; when the engine compartment bracket rotates to a suitable position, the operator can drive the plug shaft 232 to cooperate with the corresponding limiting hole 233 to fix the engine compartment bracket. This operation does not require the operator to have proficient operation skills. The operator only needs to drive the plug shaft 232 to move according to the hole positions set in the process document, and the engine compartment bracket can be fixed accurately and stably; the number and position arrangement of the limiting holes 233 are selected according to the model of the actually installed engine compartment bracket, for example Figure 2 shown. The number of the limiting holes 233 is 18, and they are circumferentially arranged on the turntable 231 at equal intervals.

[0033] The above two designs solve the problems in the prior art that in the process of installing various components of a front-wheel drive electric vehicle on the engine compartment bracket, the workload of the operator is large and the requirement for the proficiency of the operator's operation skills is high.

[0034] In another embodiment, please refer to Figure 1 and Figure 2 , the power component 22 includes a power member and a speed reducer 222. The power member is connected to the rotating shaft component 21 through the speed reducer 222. The power member drives the input shaft of the speed reducer 222 to rotate, and the output shaft of the speed reducer 222 is connected to the rotating shaft component 21. The operator can change the input direction of the power member by the speed reducer 222 according to the actual production situation, so as to enhance the applicability of the installation auxiliary fixture.

[0035] In another embodiment, please refer to Figure 2, the power component is a hand crank 221, which enables the operator to move this installation auxiliary tool to a suitable position for work without considering power supply problems, enhancing the applicability of this installation auxiliary tool.

[0036] In another embodiment, please refer to Figure 2 , the hand crank 221 and the turntable 231 are fixedly connected.

Compared with the design that the hand crank 221 and the rotating shaft component 21 are connected to the opposite surfaces of the speed reducer 222, this design not only occupies less space, but also is more convenient for the operator to observe the rotation position of the engine nacelle bracket when rotating the hand crank 221. In this embodiment, the rotation axis line 211 of the hand crank 221 and the rotation axis line 211 of the rotating shaft component 21 are perpendicular to each other, which is achieved by changing the rotation direction of the hand crank 221 through the speed reducer 222. The internal structure of the speed reducer 222 is as Figure 3 shown. Since the structure of the speed reducer 222 has been fully disclosed in the prior art, it will not be described in detail here.

[0038] In another embodiment, the power component is a motor. Compared with the design where the power component is a hand crank 221, the technical solution of this embodiment is more labor-saving for the operator. The TV can select a servo motor with button control, which will not be described in detail here.

[0039] In another embodiment, please refer to Figure 1 , it further includes a bracket 3. The rotating shaft component 21 is rotatably installed on the bracket 3 through a bearing 4. A moving component is installed on the bracket 3. The operator can move this installation auxiliary tool to a suitable position at any time according to needs by moving the bracket 3. The design of the bearing 4 enhances the stability of the rotating shaft component 21 during operation; at the same time, the moving component can select four universal wheels 5.

[0040] In another embodiment, please refer to Figure 2, the limiting member 23 further includes a limiting seat 234 and a limiting handle 235. The limiting seat 234 is fixedly installed on the bracket 3. The insertion shaft 232 is slidably installed on the limiting seat 234. The limiting handle 235 drives the insertion shaft 232 to slide along the axis direction of the turntable 231. The limiting handle 235 can convert the rotation of the handle into the translation of the insertion shaft 232 through a curved rod coupling structure, which is convenient for the operator to operate.

[0041] In another embodiment, please refer to Figure 1 , the clamping assembly 1 includes a plurality of cross beams 11 and a plurality of clamping members 12. The rotating shaft member 21 passes through a plurality of the cross beams 11, and the rotating shaft member 21 is fixedly connected to the cross beams 11. The clamping members 12 are installed on the cross beams 11; there are at least two cross beams 11, and at least three clamping members 12, and at least three of the clamping members 12 are not on the same cross beam 11, that is, the three clamping members 12 determine a working surface. Through the cooperation of the cross beams 11 and the clamping members 12, the stability of the engine room bracket during rotation is fully ensured. The clamping members 12 can be of the gravity clamping type, which will not be elaborated here.

[0042] In other embodiments, such as Figure 2 shown, the rotating shaft member 21 includes a rotating shaft 211 and a shaft sleeve 212. The rotating shaft 211 passes through a plurality of the cross beams 11; the shaft sleeve 212 is sleeved on the rotating shaft 211 and is installed between two of the cross beams 11. The two ends of the shaft sleeve 212 are respectively fixedly connected to an adjacent cross beam 11. Through the design of the shaft sleeve 212, the strength of the entire rotating shaft member 21 is enhanced, and the working reliability of this installation auxiliary tool is improved.

[0043] In summary, in the present utility model, the rotating shaft member 21 and the clamping assembly 1 are fixedly connected. The power member 22 drives the rotating shaft member 21 to rotate in a full circumferential direction. The design of the simultaneous rotation of the turntable 231 and the rotating shaft member 21 enables the operator to drive the power member 22 to drive the rotating shaft member 21 to rotate according to the specific installation component, that is, to drive the engine room bracket to rotate to a position suitable for operation and installation. Compared with the prior art of adjusting the entire fixture, the operator is more labor-saving; at the same time, through a plurality of limiting holes 233 opened on the turntable 231, the plurality of limiting holes 233 are arranged along the circumference of the turntable 231, the insertion shaft 232 is movably installed, and the insertion shaft 232 cooperates with any one of the limiting holes 233, and the design of the fixed clamping assembly 1.

This operation does not require the operator to have proficient operation skills. The operator only needs to drive the insertion shaft 232 to move according to the hole positions set in the process document to accurately and stably fix the engine room bracket. Therefore, the present utility model effectively overcomes the shortcomings in the prior art and has high industrial utilization value.
