[0002] With the rapid development of new energy vehicle technology, the line body designs and functional requirements of each automobile factory are diverse. For example, the PTC heater structure is jointly composed of a radiator, a coolant flow channel, a main control board, a high-voltage connector, a disturbance low-voltage connector, and a housing, etc.

[0003] It is a self-restoring normal type thermistor element. Due to the special structure, the stability and safety during assembly on the vehicle body are particularly concerned. The PTC heater controls the magnitude of the current to adjust the cooling power and temperature, so that the coolant of the vehicle is maintained within a suitable temperature range, ensuring the constant operation of key components such as the engine, motor, and battery.

[0004] However, during actual assembly, when the PCT fixing bracket is connected to the PCT heater, there is a lack of supporting and limiting devices. Not only will the installation of the PCT fixing bracket and the PCT heater be incomplete, but it is also easy for the PCT fixing bracket and the PCT heater to have relative displacement when tightening the fixing bolts, which not only wastes assembly man-hours but also easily causes the PCT fixing bracket to be misaligned.

[0005] The existing patent 201821877795.4 - an installation seat for a PTC heater that is convenient for installation does not clearly provide a technical inspiration for solving the above technical problems.

[0006] Therefore, in order to improve at least one of the above problems, an auxiliary device is needed to assist in realizing the connection between the PCT fixing bracket and the PCT heater. Summary of the Utility Model

[0007] The purpose of the utility model is to provide an assembly device that can ensure the stable position of the PCT heater when the PCT fixing bracket and the PCT heater are installed.

[0010] A fixing mechanism for fixing on the placement table is provided on the placement table.

[0011] The fixing mechanism includes fixing holes provided on the placement table, and fixing bolts are provided in the fixing holes.

[0012] The fixing mechanism includes magnets provided on the placement table.

[0013] The placement table includes an intermediate connection table, one side of the intermediate connection table is connected to a top fixing table, and the other side is provided with a plug-in positioning support table.

[0014] The top fixing table is provided with an inverted trapezoidal groove.

[0015] The placement sink is arranged on the intermediate connection table and the plug-in positioning support table, and the placement sink forms a limiting block at the edge of the intermediate connection table and the plug-in positioning support table.

[0016] Reinforcing trapezoidal platforms are provided between the top fixing table and the intermediate connection table, and between the plug-in positioning support table and the intermediate connection table.

[0017] The advantages of the present utility model are as follows:

[0018] The present utility model discloses an assembly device for a PTC heater.

[0019] Through the setting of the placement table, the present utility model facilitates the placement and positioning of the PTC heater to be assembled, and further facilitates the installation and connection between the subsequent PTC fixing bracket and the PTC heater. Brief Description of the Drawings

[0020] The following briefly describes the content expressed in each drawing of the specification of the present utility model and the marks in the drawings:

[0021] Figure 1 is a schematic structural diagram of the present utility model.

[0022] The marks in the above-mentioned drawings are all:

[0023] 1. Placement table, 2. Placement sink, 3. Fixing hole. Detailed Embodiment

[0024] The following further details the specific embodiments of the present utility model by describing the optimal embodiments with reference to the drawings.

[0025] An assembly device for a PTC heater includes a placement device; the placement device includes a placement table 1, and a placement sink 2 is arranged on the placement table 1; through the setting of the placement table 1, the present utility model facilitates the placement and positioning of the PTC heater to be assembled, and further facilitates the installation and connection between the subsequent PTC fixing bracket and the PTC heater.

[0026] The assembly device disclosed by the present utility model is mainly used for the installation and connection between the PTC heater and the PTC fixing bracket, and the assembly device disclosed by the present utility model mainly plays a role of supporting and limiting.

[0027] In the utility model, the placement device is mainly used to support and position the PTC heater to prevent the PTC heater from being offset and rotated during subsequent assembly.

[0028] At the same time, in the utility model, the placing device includes a placing table 1, which serves as a bottom support, and a placing trough 2 is provided on the placing table 1. The placing trough 2 facilitates the placement operation of the PTC heater to be assembled, and the side of the placing trough 2 plays a good limiting role, thereby preventing the PTC heater from deflecting when it is subsequently installed and locked with other components.

[0029] At the same time, the placement table 1 described in the utility model is provided with a fixing mechanism for fixing on the placement table 1; the fixing mechanism, as the name implies, is used to install and fix the placement table 1. Generally, the placement table 1 is installed and fixed on a workbench to facilitate the stability of the placement position of the PTC heater; there are many types of fixing mechanisms, which can be structures such as snaps and bolts.

[0030] Furthermore, in the utility model, the fixing mechanism includes a fixing hole 3 arranged on the placement table 1, and a fixing bolt is arranged in the fixing hole 3; the fixing hole 3 is generally designed to be a stepped hole structure, and the subsequent fixing bolt passes through the fixing hole 3 to connect with the workbench; thereby achieving stable placement of the placement table 1 on the workbench; in the utility model, a plurality of fixing holes 3 are arranged on the placement table 1, and each fixing hole 3 is passed through by a bolt to achieve the installation and fixation of the placement table 1.

[0031] Furthermore, in the utility model, the fixing mechanism includes a magnet arranged on the placement table 1; the magnet can be a magnet layer or an electromagnet, and the magnet is arranged at the lower end of the placement table 1, and the placement table 1 is adsorbed on the workbench through the magnet; the position of the placement table 1 on the workbench is limited by the adsorption force between the magnet and the workbench.

[0032] Furthermore, in the utility model, the placement table 1 includes an intermediate connecting table 11, one side of the intermediate connecting table 11 is connected to a top fixing table 13, and the other side is provided with a plug-in positioning support table 12; the placement table 1 of the utility model adopts a three-section structure, and such a setting can facilitate the production of the placement table 1; at the same time, in the utility model, the width of the intermediate connecting table 11 is greater than the top fixing table 13 and the plug-in positioning support table 12. Such a design makes it convenient for the PTC heater to be arranged on the plug-in positioning support table 12 in subsequent use, and a part of the structure is in an exposed state, which is convenient for subsequent application of external force to the PTC heater to make it separate from the placement table 1.

[0033] Of course, during actual design, the dimensions of the intermediate connecting platform 11, the top fixing platform 13, and the plug positioning and supporting platform 12 can be structurally and dimensionally changed according to different models and categories of PTC heaters. However, in essence, as long as the support, placement, and limitation of the PTC heater can be achieved, it is feasible.

[0034] Furthermore, in the present utility model, an inverted trapezoidal groove 131 is provided on the top fixing platform 13. Such a setting can limit the position of the lower end of the PTC heater and prevent the PTC heater from shaking laterally.

[0035] Furthermore, in the present utility model, the placement sink 2 is provided on the intermediate connecting platform 11 and the plug positioning and supporting platform 12, and the placement sink 2 forms a limiting block 21 at the edge of the intermediate connecting platform 11 and the plug positioning and supporting platform 12. In the present utility model, the limiting block 21 plays a good role in lateral limitation, preventing the PTC heater from swinging laterally when the PTC fixing bracket is tightened subsequently.

[0036] Furthermore, in the present utility model, a reinforcing trapezoidal platform 14 is provided between the top fixing platform 13 and the intermediate connecting platform 11, and between the plug positioning and supporting platform 12 and the intermediate connecting platform 11. The reinforcing trapezoidal platform 14 plays a good role in increasing the strength, ensuring the strength at the connection between the top fixing platform 13 and the intermediate connecting platform 11, and between the plug positioning and supporting platform 12 and the intermediate connecting platform 11, preventing fracture due to sudden dimensional changes, and also facilitating injection molding during production.

[0037] Specifically:

[0038] The assembly equipment disclosed in the present utility model is mainly used for the installation and connection between the PTC heater and the PTC fixing bracket, and mainly plays a role in supporting and limiting. In the present utility model, the placement device is mainly used for supporting and positioning the PTC heater to prevent the PTC heater from shifting and rotating during subsequent assembly.

[0039] The placement block disclosed in the present utility model is mainly made of plastic to ensure the strength and service life of the equipment and prevent scratches on the surface of the PTC heater.

[0040] The placement block disclosed in the present utility model is generally formed by one-time injection molding.

[0041] Generally, the raw materials are polypropylene (PP), polyethylene (PE), polystyrene (PS), etc. During actual use, the formula design can be carried out according to the requirements of the equipment product.

[0042] In the present utility model, there are two fixing methods: One is that a magnet with relatively high magnetic strength is built inside the bottom of the device, which can adsorb an iron workbench for assembly operations at any time, and can be flexibly arranged. When not in use, it can be used for other purposes. The other is the bolt fixing method. The device is fixed to a workbench made of other materials with three Q1860825 bolts and can also be assembled and used. It is flexible and applicable to different application scenarios in the production and manufacturing site, facilitating the layout of the production line body.

[0043] Specific operation process:

[0044] 1. Fix the placement block on the workbench.

[0045] Generally, there are two fixing methods for the placement block. One is to fix it on the workbench surface with bolts through its three fixing holes 3. The other is that the bottom of the device is equipped with a magnet, which is suitable for an iron workbench and can be directly placed on the tabletop for fixing.

[0046] 2. Place the front of the PTC heater in contact with the top of the placement block so that the placement block and the PTC heater are placed in coincidence and positioned.

[0047] 3. Place the PTC fixing bracket on the PTC heater so that the six mounting holes of the bracket are aligned with the six fixing holes of the PTC.

[0048] 4. Pre-tighten six fixing bolts (Q1860825), and use an electric gun to tighten them diagonally. Tightening torque: 9 ± 1 Nm.

[0049] 5. After the assembly is completed, perform self-inspection of the assembly work, and complete the assembly at one time.

[0050] Obviously, the specific implementation of the present utility model is not limited by the above methods.
