[0030] New energy vehicles are powered by batteries. While there are various ways to secure batteries to a vehicle, bolts as locks are a common method. Battery replacement in new energy vehicles is primarily performed using battery swapping equipment, which includes a locking gun. This gun unlocks and removes the battery from the vehicle, allowing it to be installed and locked.

[0031] During the process of disassembling and installing the battery, if the concentricity of the sleeve of the locking gun does not match the battery lock body, the battery cannot be accurately positioned, and the sleeve is prone to idling during the battery replacement process, affecting the battery replacement efficiency. Even if the locking and unlocking can be completed, the concentricity mismatch will cause the sleeve and the battery lock body to be easily worn, increasing the maintenance frequency and battery replacement cost. In severe cases, it will cause the battery to be falsely locked, which is very likely to cause safety accidents. Therefore, after the locking and unlocking gun is installed, the installation position of the sleeve needs to be checked to ensure that the sleeve is installed in place to avoid the problem of inaccurate matching with the battery lock body due to poor verticality of the sleeve.

[0032] Since the sleeve of the locking and unlocking gun may wear out after long-term use, which may affect the locking and unlocking efficiency of the battery, after replacing the sleeve, it is also necessary to confirm whether the sleeve is installed in place after maintenance. The battery replacement locking and unlocking gun detection device proposed in the utility model can detect whether the sleeve is installed in place after the locking and unlocking gun is assembled. It can also detect the installation position of the sleeve when the locking and unlocking gun is repaired or parts are replaced after being put into use for a period of time. If it is found that the installation position of the sleeve is deviated, the position of the sleeve can be adjusted according to the detection results, and then detection and confirmation can be performed to ensure that the assembly quality of the locking and unlocking gun meets the use requirements.

[0033] As attached Figure 1As shown, the battery replacement locking and unlocking gun detection device proposed in the utility model includes a supporting part 10, a fixing part 20 and a detecting part 30. The fixing part 20 and the detecting part 30 are installed on the supporting part 10. The locking and unlocking gun includes a gun body 40, a sleeve 41 and a driving part 42. The fixing part 20 is used to install the gun body 40. The position of the sleeve 41 matches the detecting part 30. The detecting part 30 includes a detecting part 31. One end of the detecting part 31 contacts the radial outer wall of the sleeve 41. The sleeve 41 is configured to be rotatable around its own axial direction relative to the detecting part 31. More specifically, the driving part 42 can drive the sleeve 41 to rotate. The detecting part 31 is used to detect the installation position of the sleeve 41 relative to the gun body 40, and then detect the verticality of the installation of the sleeve 41.

[0034] Optionally, the drive member 42 is a servo motor that can adjust the rotation speed of the sleeve 41 according to the detection requirements, so that the operator can observe the detection results of the detection member 31. Since the sleeve 41 needs to be driven by the drive member 42 to rotate around its own axis to achieve the locking and unlocking of the battery lock body, the present invention can directly drive the sleeve 41 through the drive member 42 of the locking and unlocking gun, and cooperate with the detection member 31 to achieve detection, saving investment costs. During the detection process, only the drive member 42 of the locking and unlocking gun needs to be activated.

[0035] The setting of the support part 10 can realize the installation of the fixing part 20 and the detection part 30, and can realize the integration of functions, so as to facilitate the fixing and detection of the locking and unlocking gun; the setting of the fixing part 20 can fix the gun body 40 to the support part 10 to avoid interference with the detection result due to shaking or position displacement of the gun body 40 during the detection process; the setting of the detection part 31 is used to contact the outer wall of the sleeve 41 in the radial direction, so as to detect the position of the outer wall of the sleeve 41 during the rotation of the sleeve 41 around its own axis, and then judge whether the position of the sleeve 41 relative to the gun body 40 is accurately installed, which can avoid the problem of tilting and insufficient verticality of the sleeve 41 due to improper installation, and can prevent the sleeve 41 from being mismatched with the concentricity of the battery lock body during the locking and unlocking process, avoid abnormal noise and wear problems during the locking and unlocking process, ensure the battery replacement efficiency, and ensure the installation quality of the battery on the vehicle, eliminate the safety hazards of false battery locks, and improve the safety of the vehicle.

[0036] Compared with manually measuring the installation position of the sleeve, the battery replacement locking and unlocking gun detection device proposed in the present invention reduces the error of manual measurement. It only needs to install the locking and unlocking gun to be detected and cooperate with the detection part 30, which reduces the difficulty of operation.

[0037] In one example embodiment, Figure 1 and attached Figure 2The supporting part 10 includes a supporting platform 11 and a supporting leg 12. The supporting leg 12 is located below the supporting platform 11 and is connected to the lower end of the supporting platform 11 to play a supporting role. The fixing part 20 and the detecting part 30 are installed on the supporting platform 11.

[0038] For example, the support platform 11 is connected to the four legs 12 by screwing, and the height and number of the legs 12 can be adjusted according to actual needs. The structure is simple and easy to disassemble, assemble and carry.

[0039] Optionally, a reinforcement piece is provided between two adjacent supporting legs 12 , and the reinforcement piece is used to connect the two adjacent supporting legs 12 to increase the stability of the supporting legs 12 .

[0040] Optionally, the supporting platform 11 and the supporting legs 12 are made of aluminum, which is light in overall weight, easy to carry, and has good strength and structural stability.

[0041] In an example scenario, as shown in the attached Figure 2 As shown, the support portion 10 also includes a measuring piece 13, which is installed on the support platform 11. The measuring piece 13 includes a reference detection hole 131, which matches the size of the standard sleeve 41. The sleeve 41 can be inserted into the reference detection hole 131 to detect whether the radial size of the sleeve 41 is qualified.

[0042] Exemplarily, the support portion 10 includes at least two measuring pieces 13 with different apertures of reference detection holes 131, so that appropriate measuring pieces 13 can be selected according to the detection requirements of different specifications of locking and unlocking guns. At least two measuring pieces 13 can also be directly pre-installed on the support platform 11 to select corresponding measuring pieces 13 according to the detection requirements.

[0043] For example, as shown in the attached Figure 2 As shown, the support platform 11 is provided with a mounting hole 111, and the measuring member 13 is accommodated in the mounting hole 111. Optionally, the measuring member 13 is interference-fitted with the mounting hole 111 to prevent the measuring member 13 from moving during the measurement process of the sleeve 41, which is conducive to ensuring accurate measurement results.

[0044] For example, as shown in the attached Figure 2 As shown, the support part 10 also includes a mask part 14, which is detachably arranged above the measuring part 13 and covers the reference detection hole 131 to block the reference detection hole 131 and prevent external dust and impurities from entering the reference detection hole 131 and affecting the detection accuracy.

[0045] Optionally, as attached Figure 2As shown, a connector 141 is provided on one side of the mask 14. Connector 141 contacts and connects to support platform 11. Connector 141 has a first fixing hole, and support platform 11 has a second fixing hole. The first and second fixing holes cooperate to secure mask 14 to support platform 11, preventing mask 14 from falling off measuring member 13. When measuring member 13 is not in use, mask 14 is secured above measuring member 13 to prevent dust. When measuring member 13 is in use, mask 14 can be removed, making operation simple and convenient.

[0046] In one example embodiment, Figure 1 and attached Figure 3 The fixing part 20 includes a fixing seat 21, which is installed on the supporting platform 11. A through-hole 211 is provided on the fixing seat 21, which penetrates the fixing seat 21 in the up and down directions. The gun body 40 is installed below the fixing seat 21. The driving member 42 is located below the fixing seat 21 and the supporting platform 11. The upper part of the gun body 40 is accommodated in the through-hole 211 so that the sleeve 41 passes through the through-hole 211 and cooperates with the detection member 31. The driving member 42 is used to drive the sleeve 41 to rotate around its own axis to cooperate with the detection member 31 to realize the detection of the installation position of the sleeve 41.

[0047] Optionally, the gun body 40 is detachably mounted below the fixing seat 21 by screw connection, and the fixing seat 21 is provided with a screw hole that cooperates with the gun body 40 .

[0048] Optionally, as attached Figure 3 As shown, the fixing seat 21 is detachably mounted on the supporting platform 11 by screw connection, so that the position of the fixing seat 21 can be adjusted according to actual needs, and disassembly, assembly and maintenance are convenient.

[0049] For example, as shown in the attached Figure 3 As shown, the fixing portion 20 also includes a positioning member 22, which is protruding from the lower end of the fixing seat 21. A positioning groove (not shown in the figure) that cooperates with the positioning member 22 is opened on the support platform 11. When the fixing seat 21 is installed on the support platform 11, the positioning member 22 is accommodated in the positioning groove to achieve rapid positioning and installation of the fixing seat 21, reducing the difficulty of installation and helping to improve installation efficiency.

[0050] Optionally, the fixing seat 21 and the positioning member 22 are integrally formed.

[0051] Optionally, the through hole 211 passes through the positioning member 22 in the up-down direction.

[0052] Optionally, as attached Figure 3 As shown, the fixing portion 20 further includes a weight-reducing groove 23 , which is provided on at least one of the fixing seat 21 and the positioning member 22 . The weight-reducing groove 23 is used to reduce the overall weight of the fixing portion 20 , thereby reducing investment costs.

[0053] In an example scenario, as shown in the attached Figure 4 As shown, the detection part 30 includes a support 32, which is installed on the support platform 11 and is used to fix the detection member 31. Figure 1 A functional hole 321 is opened on the support 32, and the detection member 31 includes a probe 311. One end of the probe 311 passes through the functional hole 321 and contacts the outer wall of the sleeve 41 in the radial direction to detect the position of the sleeve 41.

[0054] For example, as shown in the attached Figure 4 As shown, the support 32 includes a bottom support member 322 and a bracket 323. The bottom support member 322 is mounted on the support platform 11. The bracket 323 is located at the upper end of the bottom support member 322 and is connected to the upper end of the bottom support member 322. The functional hole 321 is opened on the bracket 323. The bracket 323 is used to install the detection member 31 and match the position of the detection member 31 with the sleeve 41. Optionally, the bottom support member 322 is detachably mounted on the support platform 11 by screwing.

[0055] For example, at least two functional holes 321 are vertically distributed on the bracket 323. The detection member 31 can be inserted into different functional holes 321 according to the specifications and dimensions of the sleeve 41 to adapt to different locking and unlocking gun detection. Optionally, the bracket 323 and the base member 322 are integrally formed.

[0056] For example, please refer to the attached Figure 5 The support 32 includes at least two brackets 323 of different heights, each of which is detachably mounted on the base member 322. Brackets 323 of corresponding heights can be selected based on the specifications and dimensions of the sleeve 41 to accommodate the detection of different specifications of locking and unlocking guns. Optionally, the brackets 323 and base member 322 are detachably connected by screws.

[0057] Optionally, the detection member 31 uses a dial indicator. If the installation position of the sleeve 41 deviates, there will be different forces when the probe 311 contacts the outer wall of the sleeve 41 in the radial direction during the process of the sleeve 41 rotating about its own axis. The different forces will cause the numerical pointer of the dial indicator to change. The operator can record and analyze the numerical values to determine whether the position of the outer wall of the sleeve 41 relative to the probe 311 changes during the process of the sleeve 41 rotating about its own axis, and then determine whether the installation position of the sleeve 41 meets the usage requirements.

[0058] For example, as shown in the attached Figure 4 As shown, the support 32 further includes a bushing 324, which is installed in the functional hole 321, and the probe 311 is inserted into the bushing 324. Figure 5A fixing hole 325 is opened on the bushing 324, and the fixing hole 325 passes through one side wall of the bushing 324. A fastener is passed through the fixing hole 325, and the end of the fastener contacts the probe 311 to fix the detection member 31 to the support 32.

[0059] Optionally, the bushing 324 is interference fit with the functional hole 321 .

[0060] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
